Description

Technical Field

[0001] The present invention relates to a configuration of a partition ceiling installed using a partition wall.

Background Art

[0002] In building ceiling structures, suspended ceilings are often used. A suspended ceiling has a configuration in which a ceiling frame consisting of a soffit support and a soffit is suspended from a predetermined structure (such as a ceiling slab or an H-shaped steel) in the building ceiling via a large number of suspension bolts, and a ceiling panel (such as a decorative board) is attached to the lower surface of the ceiling frame (see, for example, the configuration of Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, even in the case of a building where the depth of the ceiling, such as in a gymnasium or a concert hall, is deeper than a predetermined level, for example, in a hospital corridor where the ceiling depth is shallow, both sides are partitioned by partitions, the interval between them is narrow, and moreover, in the ceiling space where various equipment and a large number of pipes are concentrated in the ceiling space, there is a problem that these various equipment and a large number of pipes interfere with each other, and it is impossible to suspend a large number of suspension bolts from the ceiling slab portion.

[0006] The present invention has been made to solve such problems, and uses a pair of left and right partition walls, spans a predetermined connecting member between predetermined upper positions considering the installation spaces for equipment and piping between these partition walls, and uses the connecting member to directly form a ceiling frame or indirectly attach it via suspension bolts, with the aim of providing a partition ceiling.

Means for Solving the Problems

[0007] The partition ceiling of the present invention is configured with the following problem-solving means in order to solve the above problems.

[0008] (1) The first problem-solving means of the present invention First, the partition ceiling in the first problem-solving means of the present invention uses a pair of left and right partition walls, spans a predetermined connecting member at a predetermined upper position considering the installation spaces for equipment and piping between these partition walls, and installs a ceiling frame composed of a field edge receiver and a field edge using the connecting member. The pair of left and right partition walls consists of a partition base composed of a predetermined runner, a predetermined stud, and a predetermined anti-vibration device, and a gypsum board integrally provided via a predetermined metal plate at a predetermined upper position on the mutually facing surface sides of the partition base. On the other hand, the connecting member is composed of a predetermined shaped steel, and both end sides of the connecting member composed of the predetermined shaped steel are connected and fixed to a predetermined metal plate of the partition wall via a predetermined connecting and fixing fitting, and the ceiling frame is installed using the connecting member connected and fixed to the predetermined metal plate of the partition wall.

[0009] As a result, according to the above configuration, it is possible to connect and integrate the pair of left and right partition walls composed of a partition base composed of a predetermined runner, a predetermined stud, and a predetermined anti-vibration device and a gypsum board integrally provided via a predetermined metal plate at a predetermined upper position on the mutually facing surface sides of the partition base into a portal structure as a whole by the connecting member.

[0010] Moreover, the connecting member is made of a predetermined section steel with high sectional strength, and both ends of the connecting member made of the predetermined section steel with high sectional strength are firmly connected and fixed to the predetermined metal plates of a pair of left and right partition walls via predetermined connecting and fixing fittings. Therefore, the pair of left and right partition walls can be more firmly connected and integrated into a portal structure as a whole. For this reason, compared with the conventional structure in which the ceiling frame is suspended from the ceiling slab portion via suspension bolts between the pair of left and right partition walls, the strength and seismic resistance of the pair of left and right partition walls serving as support walls for supporting the ceiling frame are effectively improved.

[0011] As a result, in the case of the same structure, the connecting member itself for connecting the pair of left and right partition walls is also securely and firmly supported by the pair of left and right partition walls, and becomes a cross beam member with sufficiently high supporting strength for directly or indirectly installing the ceiling frame. And in the case of the same structure, since the ceiling frame is directly or indirectly installed using such a connecting member with high supporting strength, compared with the conventional structure in which the ceiling frame is only suspended from the ceiling slab portion via suspension bolts between the pair of left and right partition walls, the strength of the installed ceiling frame portion is also effectively improved, and as a result, the rigidity and load-bearing capacity of the entire ceiling portion can be greatly improved.

[0012] And in the case of the same structure, different from the conventional structure in which the ceiling frame is suspended from the ceiling slab portion via a large number of suspension bolts between the pair of left and right partition walls, the connecting member is spanned at a predetermined upper position considering the installation space of equipment and piping between the pair of left and right partition walls, and the ceiling frame is installed from the same position to the lower side.

[0013] Therefore, in the case of the same structure, there is nothing in the space from the connecting member to the ceiling slab on the upper side, and a completely free space can be realized. As a result, the installation of equipment and piping between the partition walls also becomes free, and the restrictions based on the installation of the ceiling frame are completely eliminated. Therefore, both workability and maintainability are improved.

[0014] Generally, as described above, a partition wall is composed of a pair of runners positioned vertically, a plurality of studs positioned between these runners and standing upright at predetermined intervals from each other, and a plurality of anti-sway members arranged at predetermined vertical intervals and connecting the plurality of studs to each other. The runners are made of metal members having a U-shaped cross section, and the upper one is fixed under the ceiling slab and the lower one is fixed on the floor slab by driving pins (or concrete nails) with their open sides facing each other. Generally, channel members (light channel steel) are adopted for the studs, and a plurality of through holes for inserting anti-sway members are provided at predetermined positions in the vertical direction. The anti-sway members are inserted through these through holes in a cross state and fixed to the studs using spacers respectively. Thereby, a plurality of studs are connected to each other and the anti-sway function is realized.

[0015] Therefore, the pair of partition bases on the left and right that constitute the main body of the partition wall are not structurally strong by themselves, and as a building structure for supporting the ceiling frame, they do not necessarily have sufficient strength and seismic resistance. In particular, there is a weakness that it is easily bent as a whole. Therefore, by connecting and integrating their vertical intermediate (midway) portions with connecting members having a high cross-sectional strength as described above at predetermined intervals in the longitudinal direction (front-rear direction) and securely supporting them at three points: the ceiling slab side, the intermediate portion side, and the floor slab side, configuring it into a rigid body with a high flexural strength in the form of a portal structure is extremely effective in improving the seismic resistance of the building structure.

[0016] (2) The second problem-solving means of the present invention Next, in the partition ceiling of the second problem-solving means of the present invention, in the configuration of the first problem-solving means, a predetermined connecting and fixing fitting for connecting and fixing both end sides of the connecting member to a predetermined metal plate of the partition wall is a U-shaped receiving portion that fits and receives both end sides of the connecting member from above downward, and a connecting and fixing fitting body including the receiving portion is adopted which has a pair of left and right mounting pieces for connecting and fixing to the partition wall side. The pair of left and right mounting pieces are provided by being preliminarily connected and fixed to a predetermined metal plate which is on the back side of the gypsum board and is attached to the partition base side using a predetermined screwing and fixing means.

[0017] In the partition ceiling of the second problem-solving means of the present invention, a connecting and fixing fitting is adopted which has a pair of left and right mounting pieces for connecting and fixing a connecting and fixing fitting body including a U-shaped receiving portion that fits and receives both end sides of a connecting member for connecting a pair of left and right partition walls to each other from above downward to each partition wall side. The connecting and fixing fitting is provided by being preliminarily connected and fixed to a predetermined metal plate which is on the back side of the gypsum board and is attached to each partition base side using a predetermined screwing and fixing means for the pair of left and right mounting pieces thereof.

[0018] Therefore, according to such a configuration, when connecting a pair of left and right partition walls to each other by a connecting member, it becomes a connectable state just by fitting both ends of the connecting member into the U-shaped receiving portions of the connecting and fixing fittings on each partition wall side from above downward. If the U-shaped receiving portion part is just screwed and fixed by a predetermined screwing and fixing means, finally, a pair of left and right partition walls can be connected and fixed, so the connecting and fixing work is extremely easy.

[0019] Moreover, in the case of such a configuration, the pair of left and right mounting pieces of the connecting and fixing fitting are attached to a predetermined metal plate which is on the back side of the gypsum board and is attached to the partition base side in advance using a predetermined screwing and fixing means, so the mounting and fixing strength is high, and the connecting and fixing strength after connection is also high. The connecting strength is high in any direction of up and down, left and right, and axial direction of the connecting member. Therefore, the earthquake resistance is also improved.

[0020] (3) Third problem-solving means of the present invention Next, in the partition ceiling in the third problem-solving means of the present invention, in the configuration of the first or second problem-solving means, a predetermined connecting and fixing fitting is attached to a predetermined metal plate on the partition base side via a predetermined metal plate for attaching the connecting and fixing fitting between the partition base side gypsum board and the partition base side predetermined metal plate.

[0021] According to such a configuration, the strength of the mounting surface of the gypsum board with insufficient strength as the connecting and fixing fitting mounting surface is sufficiently reinforced by the predetermined metal plate for attaching the connecting and fixing fitting, and the connecting and fixing fitting can be attached more firmly and stably. As a result, the connection strength between the connecting member and the partition base is also improved.

[0022] In particular, in the case of the mounting structure via the predetermined metal plate for attaching the connecting and fixing fitting, compared with the case of directly attaching to the board surface of the gypsum board, the seismic resistance against the horizontal seismic force acting parallel to the wall surface of the partition base (the board surface of the gypsum board) is greatly improved, and the seismic resistance against the horizontal seismic force acting in the direction perpendicular to the wall surface of the partition base (the board surface of the gypsum board) is also greatly improved.

[0023] (4) Fourth problem-solving means of the present invention Next, the partition ceiling in the fourth problem-solving means of the present invention is as described above First or second In the configuration of the problem-solving means, a connecting member that connects a pair of left and right partition walls to each other is configured as a soffit receiver of a ceiling frame composed of a soffit receiver and a soffit, and a soffit is directly attached to the lower surface side to form a flat ceiling.

[0024] With such a configuration, no hanging bolts are required, and no upper and lower spans for installing hanging bolts are needed either. Therefore, even in a ceiling space where the ceiling depth is shallow, both sides are partitioned by partition walls, the interval between them is narrow, and various equipment and a large number of pipes are concentrated in the ceiling space, such as in a hospital corridor, the ceiling frame can be appropriately installed with sufficient clearance without causing interference with these various equipment and a large number of pipes.

[0025] Also, in the case of such a configuration, since the connecting member and the ceiling frame are integrally formed, a pair of left and right partition walls are integrated in a portal shape via the ceiling frame. Therefore, the strength of the building structure including the entire ceiling frame and partition walls is further improved, and it becomes more earthquake-resistant.

[0026] (5) The fifth problem-solving means of the present invention Next, the partition ceiling in the fifth problem-solving means of the present invention is characterized in that, in the configuration of the fourth problem-solving means, the edge is made of a square steel pipe, a predetermined-diameter opening for screwing is provided on the lower surface of the edge, and the edge is attached by screwing the upper surface to the lower surface of the connecting member through the opening.

[0027] According to such a configuration, the strength of the edge itself is increased, and by screwing the edge with high strength to the lower surface of the connecting member with high strength that functions as an edge support and connects a pair of left and right partition walls, the edge can be easily and firmly attached.

[0028] As a result, orthogonal clips and the like become unnecessary, and the attachment work of the edge becomes very easy. Also, since the edge is formed of a square steel pipe with high strength and is directly integrated with the lower surface of the connecting member with extremely high strength connected to a pair of left and right partition walls, its attachment strength is sufficiently high.

[0029] (6) The sixth problem-solving means of the present invention Next, the partition ceiling in the sixth problem-solving means of the present invention is as described above First or secondIn the configuration of the problem-solving means, the gypsum board is characterized by being composed of a plurality of sheets laminated together.

[0030] In this way, when a plurality of gypsum boards are laminated together, the thickness of the gypsum board portion for fixing the connecting and fixing fittings to a predetermined metal plate on the partition base side becomes thicker, making the screw-fastening operation of the connecting and fixing fittings to the predetermined metal plate on the partition base side easy and stable.

[0031] (7) The seventh problem-solving means of the present invention Next, in the partition ceiling in the seventh problem-solving means of the present invention, in the configuration of the above First or second problem-solving means, a connecting member for connecting a pair of left and right partition walls to each other is configured as a cross beam for suspending the ceiling frame, and a ceiling frame composed of a field edge receiver and a field edge is configured to be suspended from the connecting member via a suspension bolt.

[0032] With such a configuration, even in the case of, for example, a hospital corridor, specifically when the depth of the ceiling is deep, it becomes possible to realize a suspended ceiling structure using suspension bolts (short) according to the case while sufficiently ensuring the strength of the portal structure by the connecting member.

[0033] (8) The eighth problem-solving means of the present invention Next, in the partition ceiling in the eighth problem-solving means of the present invention, in the configuration of the above First or second problem-solving means, the studs of the partition base constituting a pair of left and right partition walls are square studs, and the connecting member for connecting a pair of left and right partition walls to each other is configured by a square steel pipe.

[0034] In the case of such a configuration, the strength and rigidity of the partition base and the connecting member are greatly improved, and the ceiling frame support strength of the ceiling frame support portion composed of the portal structure and the seismic resistance of the building structure are respectively greatly improved.

[0035] (9) The ninth problem-solving means of the present invention Next, the partition ceiling in the ninth problem-solving means of the present invention is as described above First or second In the configuration of the problem-solving means, the studs of the partition base that form the pair of left and right partition walls are grooved studs with lips, and the connecting members that connect the pair of left and right partition walls to each other are composed of lip grooved steel.

[0036] In the case of such a configuration, although inferior to rectangular studs and rectangular steel pipes respectively, both have lip portions and have a cross-sectional strength close to that of rectangular studs and rectangular steel pipes. Therefore, the strength and rigidity of the partition base and the connecting members are effectively improved, and the ceiling frame support strength of the ceiling frame support portion composed of the portal structure and the seismic resistance of the building structure are effectively improved. Also, compared with rectangular studs and rectangular steel pipes, relative weight reduction and cost reduction can be achieved.

Effect of the Invention

[0037] As a result, according to the present invention, the strength, rigidity, and seismic resistance of the partition ceiling including the partition wall can be effectively improved. Also, in the case of a flat ceiling structure without using suspension bolts, as well as in the case of a suspended ceiling using suspension bolts, as short suspension bolts as possible are sufficient, and a facility space as wide as possible can be secured above the ceiling, so the engagement with necessary facilities and piping is also good.

Embodiments for Carrying Out the Invention

[0039] Hereinafter, with reference to the attached FIGS. 1 to 56, some specific embodiments for implementing the configuration of the partition ceiling of the present invention, which uses a pair of left and right partition walls and is installed between the pair of left and right partition walls via a connecting member, will be described in detail.

[0040] <Regarding the configuration of the partition ceiling according to Embodiment 1 of the present invention: FIGS. 1 to 12> First, FIGS. 1 to 3 show the overall configuration of a predetermined length portion of the partition ceiling according to Embodiment 1 of the present invention installed using a pair of left and right partition walls. FIG. 1 is a perspective view of the entire predetermined length portion, FIG. 2 is a front view of the entire predetermined length portion, and FIG. 3 is a bottom view (lower surface view) of the entire predetermined length portion.

[0041] As described above, the partition ceiling according to Embodiment 1 of the present invention is installed, for example, in a building having a pair of partition walls on both the left and right sides, such as a hospital corridor. By directly connecting and fixing the left and right end sides of a connecting member that forms a base edge receiver at a predetermined upper position of the left and right partition walls using the left and right partition walls on both sides, it is firmly attached.

[0042] That is, in FIGS. 1 to 3, first, reference numerals 1, 1 indicate a pair of partition walls installed on the left and right sides of the corridor in the hospital or the like.

[0043] These pair of left and right partition walls 1, 1 respectively consist of a pair of runners 11, 11 positioned vertically, a plurality of studs (intermediate columns) 12, 12 ··· positioned between the runners 11, 11 and erected at a predetermined interval from each other, a plurality of anti-sway members 13, 13 ··· arranged at a predetermined vertical interval and connecting the plurality of studs 12, 12 ··· to each other to form a partition base (reference numeral omitted), zinc-plated steel plates (hot-dip galvanized steel plates) 14, 14 with a predetermined vertical width firmly screwed to the portions of the studs 12, 12 ··· of the partition base (the length in the front-rear direction corresponds to the length of the runners 11, 11, the length of the anti-sway members 13, 13 ···, and the width between the front and rear end-side studs 12, 12), and gypsum boards 15, 15 (with a thickness of about 12.5 mm) attached to the opposing surface sides of the pair of left and right partition bases via the zinc-plated steel plates (with a thickness of about 0.8 mm) 14, 14 (the width in the front-rear direction corresponds to the length of the runners 11, 11, the length of the anti-sway members 13, 13 ···, and the width between the front and rear end-side studs 12, 12, and the height in the vertical direction corresponds to the dimension between the upper and lower runners 11, 11 via the studs 12, 12, that is, the height of the partition base).

[0044] The runners 11, 11 of each of the left and right partition bases are each formed of a channel member (light channel steel) with a U-shaped cross-section, and the upper one and the lower one are fixed by driving driving pins (or concrete nails) into the lower surface of the ceiling slab and the upper surface of the floor slab respectively with their open sides facing each other (illustration omitted). Also, in the case of this embodiment, the studs 12, 12 ··· are formed of square studs with a cross-sectional structure having a large dimension in the left-right direction and a small dimension in the front-rear direction (it is also possible to adopt square steel pipes similar to the connecting member 31 described later), and a plurality of through holes for inserting anti-sway members (penetrating coaxially at the same position in the parallel arrangement direction) are provided at predetermined positions in the vertical direction respectively.

[0045] This through-hole for anti-vibration insertion, as shown in FIG. 4 for example, has an anti-vibration fixing groove 12a provided with clamping ribs (protrusions) 12b, 12b on the lower side, and a finger insertion port 12c through which a finger can be inserted inside the upper side. An anti-vibration fixing piece (U-shaped cutting plate) 17 that can be bent and opened and closed like a door is provided in the middle between them. The anti-vibration fixing piece 17 can be bent (opened and closed) in both the inner and outer directions around its base portion (the portion without a cutting groove) 17a like a door. For example, when the finger is inserted into the finger insertion port 12c of the fixing piece main body portion in the closed state as shown in FIG. 4 and bent 90 degrees or more to the left from the tip side to the front side, the entire area from the upper-side finger insertion port 12c to the lower-side anti-vibration fixing groove 12a is greatly opened. Therefore, in this open state, for example, the anti-vibrations 13, 13... with a channel structure are inserted with the non-web side (flange portion side) facing downward. And when the whole is inserted, then the anti-vibrations 13, 13... are continuously pushed downward and pushed into the anti-vibration fixing groove 12a, and the flange portions on both the left and right sides are clamped by the clamping ribs 12b, 12b on both the left and right sides. Thereby, the movement of the anti-vibrations 13, 13... in the left-right direction is surely fixed. After that, the fixing piece main body portion of the anti-vibration fixing piece 17 bent to the left is returned to the original closed state as shown in FIG. 4. As a result, the anti-vibrations 13, 13... that are pushed into the anti-vibration fixing groove 12a, clamped by the left and right clamping ribs 12b, 12b and fixed left and right are further surely fixed up and down by the anti-vibration fixing piece 17. Therefore, in the case of such a configuration, there is no need for an accessory fitting (separate member) for anti-vibration fixing as in the case of fixing using a spacer, and the anti-vibration fixing work becomes significantly easier. Also, the accessory fitting for anti-vibration fixing does not come off due to the occurrence of an earthquake, and a reliable fixed state can be maintained.

[0046] Thereby, the plurality of studs 12, 12... are interconnected by the anti-vibrations 13, 13..., and a reliable anti-vibration function is realized.

[0047] In this way, a partition base of a lattice structure (a top and bottom two-point support structure) composed of runners 11, 11, studs 12, 12··, and restraints 13, 13·· is formed, with the upper side fixed to a ceiling slab (not shown) and the lower side fixed to a floor slab (not shown). And on this partition base, zinc-plated steel plates (about 0.8 mm thick) 14, 14 with the predetermined vertical width are first screwed to the ceiling attachment parts on the opposing surfaces of each other, and further, gypsum boards (about 12.5 mm thick) 15, 15 are pasted on the zinc-plated steel plates 14, 14 as described above, and finally, a pair of left and right partition walls 1, 1 as shown in FIGS. 1 to 7 are formed.

[0048] In this case, the zinc-plated steel plates 14, 14 with the predetermined vertical width are screwed to the inner opposing surfaces of a plurality of studs 12, 12·· that make up the partition base. However, in the case of this embodiment, square studs are adopted for the studs 12, 12··, so their cross-sectional strength is high and the mounting strength of the zinc-plated steel plates 14, 14 is also high. Also, in the same sense, the pasting strength of the gypsum boards 15, 15 is high. Further, each of the plurality of studs 12, 12·· is securely connected and fixed in both the vertical and horizontal directions without looseness by a plurality of restraints 13, 13·· with high connection and fixing strength as described above, so the flatness accuracy of the gypsum board mounting surface is high, and the entire gypsum board 15, 15 is pasted to the inner surface of the partition base surely and uniformly without steps. As a result, the connection accuracy of the connecting and fixing fittings 2, 2 via the gypsum board 15, 15 to the zinc-plated steel plates 14, 14 described below is also high, and the fixing strength after connection is improved.

[0049] Next, the pair of left and right partition walls 1, 1 formed in this way are connected and fixed in a portal structure (H-shaped structure) by connecting members 31, 31, 31 for installing the ceiling frame at positions corresponding to the galvanized steel plates 14, 14. In the case of this embodiment, the connecting members (hereinafter simply referred to as connecting members) 31, 31, 31 for installing the ceiling frame are made of square steel pipes in particular (in this example, as an example, for example, a square steel pipe with a corner caulking type and a plate thickness of about 0.8 mm shown in FIG. 2 of Japanese Patent Application Laid-Open No. 2020-7882 related to the development of the applicant of this case, which has particularly high cross-sectional strength is adopted).

[0050] On the other hand, at the connection positions (ceiling frame installation positions) on the side of the partition walls 1, 1 corresponding to the left and right ends of the connecting members 31, 31, 31, for example, as shown in FIGS. 4 to 7, connecting and fixing brackets (end fixing brackets) 2, 2, 2, 2, 2, 2 for connecting and fixing the left and right end portions 31a, 31a of the connecting members 31, 31 to the partition walls 1, 1 are attached.

[0051] This connecting and fixing fitting 2 (described by taking one out of the six shown in the figure as an example) is, for example, as shown in FIGS. 8 to 10, a metal plate body 21 bent into a U shape in the horizontal left-right direction as a whole. A rear end side portion is cut out from the middle portion in the front-rear direction of a pair of left and right parallel side plates 21a, 21a over a predetermined width (a width approximately 1 / 3 of the overall dimension in the up-down direction), and the cut plate portion is integrally extended left and right in a substantially flat state with the rear end side back plate 21b portion, thereby forming a pair of left and right mounting flange portions (a pair of left and right ear-shaped mounting pieces) 21c, 21c. The mounting portion of this pair of left and right mounting flange portions 21c, 21c to the partition wall 1, 1 side is formed into a rib surface structure with a reinforcing effect (step) by being press-formed forward by a predetermined height except for a predetermined width portion of its outer peripheral edge. Further, at the lower ends of the pair of left and right side plates 21a, 21a, end support pieces 21d, 21d of a pair of left and right connecting members 31 of a predetermined width bent inward in the horizontal direction are provided over the length from the front end side to the middle portion position in the rearward side (the portion on the rearward side of the middle portion position is configured on the mounting surface of the field edge 32: refer to the cross-sectional view of FIG. 4). And thereby, a U-shaped receiving portion for fitting and receiving both end portions 31a, 31a of the connecting member 31 from above is formed. Further, on the upper and lower portions of the pair of left and right side plates 21a, 21a on the front side of the cutout openings 21e, 21e, four screw holes 21g, 21g, 21g, 21g are respectively provided, on the upper and lower portions of the rear end side back plate 21b portion, two screw holes 21h, 21h are respectively provided, and further, on the pair of left and right mounting flange portions 21c, 21c, two screw holes 21i, 21i, 21i, 21i are provided at a predetermined interval from each other. In fact, only the outer screw holes are used among these two screw holes 21i, 21i, 21i, 21i on each side.

[0052] Furthermore, on the upper and lower sides of the pair of left and right side plates 21a, 21a on the front side of the cutout openings 21e, 21e, four screw holes 21g, 21g, 21g, 21g are respectively provided, on the upper and lower portions of the rear end side back plate 21b portion, two screw holes 21h, 21h are respectively provided, and further, on the pair of left and right mounting flange portions 21c, 21c, two screw holes 21i, 21i, 21i, 21i are provided at a predetermined interval from each other. In fact, only the outer screw holes are used among these two screw holes 21i, 21i, 21i, 21i on each side.

[0053] Further, at the upper and lower middle portions of the back plate 21b of the connecting and fixing fitting 2 and at the middle portions of the ends of the pair of left and right mounting flanges 21c, 21c, there are provided V-shaped grooves 2a, 2b, 2c, 2d (two sets each for the upper, lower, left, and right) which are marks for attaching the connecting and fixing fitting 2 to an appropriate mounting position in alignment with the marking line of the gypsum board 15. Based on these, it is accurately attached to the front side of the gypsum board 15 (see the perspective view in Fig. 7).

[0054] And the connecting and fixing fitting 2 configured in this way is first attached and integrated firmly to the galvanized steel plates 14, 14 in the middle of the partition wall 1, 1 through the gypsum boards 15, 15 by screws 21j, 21j, 21k, 21k using the screw holes 21h, 21h in the back plate 21b portion on the rear end side, the screw holes 21i, 21i, 21i, 21i in the pair of left and right mounting flanges 21c, 21c, as shown in Figs. 4 to 7 for example.

[0055] Then, afterwards, the end portions 31a, 31a, 31a, 31a, 31a, 31a of the connecting members 31, 31, 31 for installing the ceiling frame are fitted and connected to the pair of left and right connecting and fixing fittings 2, 2, 2, 2, 2, 2 on the partition wall 1, 1 side. The fixing of the end portions 31a, 31a, 31a, 31a, 31a, 31a of the connecting members 31, 31, 31 to the connecting and fixing fittings 2, 2, 2, 2, 2, 2 is performed by screwing screws 21n, 21n into only any two sets of screw holes 21g, 21g in the diagonal direction out of the four sets of screw holes 21g, 21g, 21g, 21g in each of the pair of left and right side plates 21a, 21a. In this case, a configuration is adopted in which the diagonal positions are changed and screwed on the left and right side plates 21a, 21a.

[0056] Incidentally, in the case of the partition ceiling structure of this embodiment, the connecting members 31, 31, 31 that connect between the pair of left and right partition walls 1, 1 using the pair of left and right connecting and fixing brackets 2, 2, 2, 2, 2, 2 as described above are configured as edge receivers that are themselves part of the ceiling frame 3. A plurality of edges 32, 32... are directly attached to the lower surface side of the connecting members 31, 31, 31 in a state of intersecting in the orthogonal direction, and a ceiling board (gypsum board) 4 made of a predetermined material is further attached to the lower surface side of these edges 32, 32... to form a partition ceiling.

[0057] In the case of this embodiment, the connecting members 31, 31, 31 that constitute the edge receivers of the ceiling frame 3 are square steel pipes with particularly high cross-sectional strength (square steel pipes with a corner caulking type plate thickness of about 0.8 mm) as described above, and moreover, they have a cross-sectional structure with a large vertical dimension and a small horizontal dimension and high load strength.

[0058] And in this fixation, each end portion 31a, 31a of the connecting member 31 made of the square steel pipe is inserted (fitted downward from the upper side) between the pair of left and right side plates 21a, 21a of the connecting and fixing metal fittings 2, 2 that have been attached to the partition walls 1, 1 side in advance as described above, as shown in FIGS. 4 and 5, and temporarily fixed. Then, screws 21n, 21n, 21n, 21n are screwed through the diagonal screw holes 21g, 21g, 21g, 21g in the diagonal directions where the positions of the pair of left and right side plate portions 21a, 21a are different from each other to finally and firmly fix. As a result, the intermediate portions in the vertical direction (the intermediate portion between the ceiling slab fixing portion and the floor slab fixing portion via the runners 11, 11) of the pair of left and right partition walls 1, 1 are connected and integrated with each other in a portal (H-shaped) by the connecting members 31, 31, 31 made of the square steel pipe having high cross-sectional strength and load strength. Therefore, the support strength of the pair of left and right partition walls 1, 1 is enhanced from the two-point support state only of the ceiling slab fixing portion and the floor slab fixing portion via the conventional upper and lower runners 11, 11 to a three-point support state including the support of the intermediate portion thereof. As a result, the rigidity and the deflection strength are greatly improved. Moreover, this connecting portion is formed uniformly over the whole in a form that continues at a predetermined interval in the front-rear direction (longitudinal direction) of the pair of left and right partition walls 1, 1 by a plurality of connecting members 31, 31, 31 ···. Therefore, the rigidity and strength of the pair of left and right partition walls 1, 1, which are basically composed of the runners 11, 11, the studs 12, 12 ···, the anti-sway members 13, 13 ···, and the gypsum boards 15 and are not necessarily high in strength, are effectively reinforced.

[0059] Next, on top of that, using orthogonal clips 33, 33... as shown in FIGS. 11 and 12, edge members 32, 32... made of square steel pipes with the same high strength as the connecting member 31, which is the edge receiver, are attached in the crossing direction to the lower side of the connecting member 31. The orthogonal clips 33, 33... are, for example, of a single type (single clip) where the attachment part 33b for the lower side edge member 32 shown in FIG. 11 is only on either the left or right side, and a double type (double clip) where the lower side attachment part 33b shown in FIG. 12 is on both the left and right sides straddling the connecting member 31 which is the edge receiver. There are two types of these, but in reality, depending on the case, one of these types is adopted. In the illustrated example (for example, FIGS. 1 and 2), for the sake of convenience, these two types of clips are combined and used to show the attachment state of each for reference. However, in the actual attachment state (construction state), it is unified with one type of clip according to the application.

[0060] Both the single clip in FIG. 11 and the double clip in FIG. 12 are configured with an engaging part 33a with a hook structure on the upper side for engaging with the upper part of the connecting member 31 and an edge attachment part 33b with an inverted U - shaped structure on the lower side. They are respectively configured with screw holes 33c, 33c and screw holes 33d, 33d on the contact surface with the connecting member 31 and the contact surface with the edge member 32. And, as shown in FIGS. 1 to 7 for example, by screwing screws 33e, 33e, 33f, 33f through these screw holes 33c, 33c, 33d, 33d, the edge members 32, 32... are attached to the connecting member 31 which is the edge receiver. And in this case, the edge members 32, 32... are also composed of square steel pipes with high strength like the connecting member 31. Therefore, the strength of the edge members 32, 32... part is also high like the connecting member 31.

[0061] Incidentally, in the case of this embodiment, a field edge 32 is also attached to the lower surface portion of the connecting end 31a of the connecting member 31 connected and fixed to the connecting and fixing fitting 2. However, since there are the side plates 21a, 21a of the connecting and fixing fitting 2 with a thick plate thickness on the left and right of this portion, common orthogonal clips 33 as shown in FIGS. 11 and 12 cannot be used (there are also reinforcing ribs 21f, 21f and the dimensions do not match). Moreover, the field edge 32 is a square steel pipe and its entire body has a closed cross-section.

[0062] Therefore, in this portion, for example, as shown in FIGS. 4 and 5, a large-diameter hole (reference numeral omitted: see FIG. 5) for screwing is drilled on the lower surface side of the field edge 32 made of the square steel pipe with a hole saw, and the upper surface side is screwed through the large-diameter hole using a screw 21m to the lower surface of the central portion in the width direction of the connecting side end 31a of the connecting member 31.

[0063] As a result of these, according to the above configuration, first, galvanized steel plates 14, 14... extending in the front-rear direction are screwed to the square stud 12, 12... portions of the partition base consisting of channel-structured runners 11, 11..., high-strength square studs 12, 12..., and channel-structured anti-vibration members 13, 13.... By this, a plurality of square studs 12, 12... arranged in parallel at a predetermined interval in the front-rear direction are connected and fixed to each other by the galvanized steel plates 14, 14... and do not relatively slide between the upper and lower slab side runners. As a result, the seismic resistance in the wall surface direction of the partition base can be greatly improved. Then, gypsum boards 15, 15... are attached to such a partition base, and a pair of left and right partition walls 1, 1 are formed. Therefore, the seismic resistance in the wall surface direction of the partition walls 1, 1 is improved, and at the time of an earthquake, the partition walls 1, 1 do not swing in the wall surface direction and their front and rear both end sides do not collide with the fixed walls of the building and get damaged.

[0064] And in the case of the above configuration, a plurality of connecting members 31, 31 ··· for forming the ceiling frame 3 are arranged at a predetermined interval in the front-rear direction (wall surface direction) between the pair of left and right partition walls 1, 1, and each of their end portions 31a, 31a ··· is fixed by connecting fixing brackets (end fixing brackets) 2, 2 ··· as shown in FIGS. 8 to 10, via the gypsum boards 15, 15 ···, to the galvanized steel plates 14, 14 ··· screwed to the square studs 12, 12 ··· on the partition base side, and are connected and fixed by screwing.

[0065] As a result, the pair of left and right partition walls 1, 1 with improved strength in the wall surface direction are firmly connected and fixed to each other by a plurality of connecting members 31, 31 ··· arranged in the wall surface direction, and are integrally connected in a portal (H-shaped) as a whole. Moreover, square steel pipes with particularly high cross-sectional strength, such as corner caulking steel pipes, are adopted for the connecting members 31, 31 ···. Therefore, the connecting and fixing strength is sufficiently high. For this reason, the pair of left and right partition walls 1, 1 also greatly improve the seismic resistance strength in the direction orthogonal to their respective wall surfaces. Therefore, the pair of left and right partition walls 1, 1 also have sufficient strength as a building structure for supporting the ceiling frame 3, and are optimal as the partition walls of the present embodiment in which the ceiling is installed with walls.

[0066] Furthermore, in the above configuration, the ceiling frame 3 composed of the edge receivers and the edges uses a plurality of connecting members 31, 31 ··· that connect the pair of left and right partition walls 1, 1 as edge receivers, and a plurality of edges 32, 32 ··· are attached to the lower portions of the plurality of connecting members 31, 31 ···.

[0067] That is, in the case of the partition ceiling of this embodiment, a plurality of edge members 32, 32... are directly connected to a plurality of high-strength connecting members 31, 31... that connect the pair of left and right partition walls 1, 1 to each other to form a ceiling frame 3. The plurality of high-strength connecting members 31, 31... substantially constitute the edge receivers of the ceiling frame 3. Therefore, in the case of the same configuration, it can also be considered that the ceiling frame 3 itself is attached in a structure directly connected to the pair of left and right partition walls 1, 1. Moreover, not only the connecting members 31, 31... that constitute the edge receivers of the ceiling frame 3, but also the edge members 32, 32... are formed of high-strength square steel pipes. Therefore, the rigidity, strength, and seismic resistance of the ceiling frame 3 itself are also high. Therefore, finally, the partition ceiling of this embodiment that is integrated with the pair of left and right partition walls 1, 1 and constructed in a portal (H-shaped) form is extremely strong and excellent in seismic resistance.

[0068] Therefore, different from the conventional configuration in which a ceiling frame having a single structure composed of an edge receiver and an edge is suspended from the ceiling slab portion via a suspension bolt between the pair of left and right partition walls 1, 1, there is fundamentally no swinging portion, and the strength and seismic resistance of the ceiling frame 3 and the ceiling frame support portion (support wall) are much higher.

[0069] Also, in the case of the same configuration, different from the conventional configuration in which a ceiling frame is suspended from the ceiling slab portion via a large number of suspension bolts between a pair of left and right partition walls, the plurality of connecting members 31, 31... are connected in a form that spans at a predetermined upper position considering the installation space for equipment and piping between the pair of left and right partition walls 1, 1, and the ceiling frame 3 is configured at the same upper position.

[0070] Therefore, in the case of the same configuration, there is nothing in the space up to the ceiling slab above the connecting members 31, 31..., and a completely free space can be realized. As a result, the installation of equipment and piping between the partition walls 1, 1 becomes completely free, and the constraints based on the installation of the ceiling frame 3 are completely eliminated. Therefore, both the workability and maintainability of the installation work are improved.

[0071] Furthermore, in the case of the above configuration, the connecting and fixing fittings (end fixing fittings) 2, 2... for connecting and fixing both ends of the above connecting members 31, 31... to the galvanized steel plates 14, 14... of the above partition walls 1, 1 have a U-shaped cross-section receiving part for fitting and receiving both end parts 31a, 31a of the connecting members 31, 31... from above downward, and a pair of left and right mounting flange parts 21c, 21c for securely and firmly connecting and fixing the connecting and fixing fitting main bodies 21, 21 including the same receiving part to the partition wall 1, 1 side. The connecting and fixing fittings are configured to be securely and firmly connected and fixed to the galvanized steel plates 14, 14 which are located on the back side of the gypsum boards 15, 15 and are attached to a plurality of square studs 12, 12... of the partition base via screwing means such as screws 21k, 21k.

[0072] Therefore, the connection work between the pair of left and right partition walls 1, 1 and the plurality of connecting members 31, 31... is extremely easy, and the workability is also excellent.

[0073] As described above, when a plurality of square studs 12, 12... are adopted for the partition base 1, 1, the strength of the studs themselves is higher than that of the channel structure (groove structure) studs, and the support parts of the anti-vibration members 13, 13... are four-point supported. Therefore, if the fixed side 17 of the above-described door structure is closed, a strong fixed structure can be realized, and the strength and seismic resistance of the partition base 1, 1 itself are also improved. In addition, in the case of the above-described fixing piece (spacer) 17 of the door structure, since the fixing piece 17 itself is integrated with the studs 12, 12... at the base part 17a, there is no risk of falling due to an earthquake or other vibrations like a spacer with a separate member structure, so the above strength can be maintained permanently.

[0074] In this case, instead of the so-called square studs as described above, it is also possible to adopt high-strength square steel pipes (corner caulking steel pipes) similar to the above-described connecting members 31, 31... for the plurality of studs 12, 12.... When such square steel pipes are adopted, the strength of the stud 12, 12... part is further improved, and the strength and seismic resistance of the partition base and the partition wall 1, 1 parts are further improved.

[0075] Therefore, it can be sufficiently applied not only to, for example, the corridors of the hospital described above, but also to the ceilings of high-ceiling buildings such as warehouses, etc., where there are partitions on the left and right, at the ceilings of the partitioned parts.

[0076] In addition, in the above description, a plurality of studs 12, 12... are described as being of the square type, but it is also possible to change them to the groove type.

[0077] <Regarding the structure of the partition ceiling according to the first modification of the first embodiment: FIGS. 13 and 14> In the case of the above-described embodiment, as described above, the connecting and fixing fitting 2 uses each of the back plate 21b portion and the pair of left and right mounting flange portions 21c, 21c, and any one of the screw holes 21h, 21h and the screw holes 21i, 21i, and is screwed and fastened to the galvanized steel plates 14, 14 on the back side of the gypsum boards 15, 15 by screws 21j, 21j and screws 21k.

[0078] That is, in the case of the same configuration, there are galvanized steel plates 14, 14 on the back side of the fastening portion, but there is no steel plate on the front side where the connecting and fixing fitting 2 abuts, and the board surfaces of the gypsum boards 15, 15 serve as the direct mounting surfaces. Moreover, the mounting surface on the side of the corresponding connecting and fixing fitting 2 is a fastening surface with a narrow corresponding area of only the back plate 21b portion and the mounting flange portions 21c, 21c. Moreover, the same portion is also press-molded for reinforcement, and the central portion side bulges, so the width of the abutting surface on the outer periphery is narrower. Therefore, if it is strongly screwed at a predetermined level or more, there is a concern that these mounting surfaces will bite into the board surfaces of the gypsum boards 15, 15 and it will not be possible to maintain a stable mounting state.

[0079] Therefore, in this Modification 1, assuming such a case, for example, as shown in FIG. 13, on the connection and fixing fitting attachment surfaces of the gypsum boards 15, 15, a rectangular galvanized steel plate (about 0.8 mm thick) 6 of a size capable of covering the entire back plate 21b portion and the pair of left and right mounting flange portions 21c, 21c of the connection and fixing fitting 2 as shown in FIG. 14 is pre-attached, and the connection and fixing fitting 2 is configured to be attached via this galvanized steel plate 6. The same galvanized steel plate as the above-described galvanized steel plate 14 on the back side is adopted for this galvanized steel plate 6.

[0080] That is, as shown in FIG. 14, the galvanized steel plate 6 is provided with small-diameter screw holes 61, 61 ··· for screwing and fixing the galvanized steel plate 6 to the galvanized steel plate 14 on the back side via the gypsum board 15 with the same screws (not shown) as above, and large-diameter screw insertion holes (over-sized holes) 62, 62 ··· through which screws 21j, 21j and screw 21k for attaching the back plate 21b and the pair of left and right mounting flange portions 21c, 21c of the connection and fixing fitting 2 are passed after screwing and fixing to the front surface of the gypsum board 15.

[0081] Therefore, when the connection and fixing fitting 2 is attached to the front side of the gypsum board 15 via such a galvanized steel plate 6, even if it is strongly screwed at a predetermined level or higher, the back plate 21b portion and the pair of left and right mounting flange portions 21c, 21c of the connection and fixing fitting 2 will not bite into the board surface of the gypsum board 15, and it can be firmly attached in a stable state. That is, the galvanized steel plate 6 functions as a reinforcing plate for increasing the strength of the board surface (connection and fixing fitting 2 attachment surface) of the gypsum board 15.

[0082] As a result, the connection and fixing strength of the end portion 31a of the connecting member 31 and the connection strength of the left and right partition walls 1, 1 by the connecting member 31 are also improved. In particular, in the case of such an attachment structure via the galvanized steel sheet 6, compared with the case of directly attaching to the board surface of the gypsum board 15, the seismic resistance against the horizontal seismic force acting parallel to the wall surface of the partition wall 1 (the board surface of the gypsum board 15) is greatly improved, and the seismic resistance against the horizontal seismic force acting in the direction orthogonal to the wall surface of the partition wall 1 (the board surface of the gypsum board 15) is also greatly improved. Therefore, it is possible to contribute to the stronger integration of the pair of left and right partition walls 1, 1 and the connecting member 31 and the improvement of the seismic resistance.

[0083] In addition, when attaching the galvanized steel sheet 6 to the front surface of the gypsum board 15, V-shaped grooves 6a, 6b, 6c, 6d serving as marks for the vertical and horizontal attachment positions are provided in the middle of each of the upper, lower, left, and right sides on the galvanized steel sheet 6 side. Then, the galvanized steel sheet 6 is attached at an appropriate position by attaching it in accordance with the lines marked with ink vertically and horizontally on the front surface side of the gypsum board 15.

[0084] On the other hand, as already described, similar V-shaped grooves 2a, 2b, 2c, 2d for attaching itself in accordance with the inked lines of the gypsum board 15 are provided in the upper and lower middle portions of the back plate 21b of the connecting and fixing fitting 2 and the middle portions of the ends of the pair of left and right mounting flanges 21c, 21c. Therefore, when the galvanized steel sheet 6 is provided, it is similarly attached at an appropriate position by attaching the V-shaped grooves 2a, 2b, 2c, 2d in accordance with the V-shaped grooves 6a, 6b, 6c, 6d of the galvanized steel sheet 6.

[0085] <Regarding the structure of the partition ceiling according to Modification Example 2 of Embodiment 1: Figures are omitted> The galvanized steel sheet 6 is not limited to the rectangular shape individually provided corresponding to the connection surfaces of the individual connecting fittings 2, 2 ··· as in Modification Example 1, and can be changed to, for example, a horizontally long shape with the same shape and dimensions as the galvanized steel sheet 14 on the back surface side of the gypsum board 15 described above.

[0086] With such a configuration, the pair of galvanized steel sheets 14 and 15 on the front and back of the gypsum board 6 , 14 firmly connect the square studs 12, 12... that were only fixed by fitting at the upper and lower runners 11, 11 and engagement at the anti-sway members 13, 13... As a result, the longitudinal strength (wall surface direction) of the pair of partition walls 1, 1 composed of the gypsum board 15 and the partition base is greatly improved, and the connection strength (axial direction and direction perpendicular to the axis) of the plurality of connecting members 31, 31... that connect them and the ceiling frame support strength (load-bearing strength) are also greatly improved. As a result, the seismic resistance of each of these parts is also greatly improved.

[0087] <Configuration of the partition ceiling according to Embodiment 2 of the present invention: FIGS. 15 to 22> First, FIGS. 15 to 22 show the overall configuration of a predetermined length portion of a partition ceiling according to Embodiment 2 of the present invention installed using a partition base. FIG. 15 is a perspective view of the entire predetermined length portion, FIG. 16 is a front view of the entire predetermined length portion, FIG. 17 is a bottom view of the entire predetermined length portion, FIG. 18 is an enlarged perspective view of a main part as seen from the partition wall side (partition base side) showing the configuration of a pair of left and right partition walls and connecting members connecting these partition walls to each other in the partition ceiling of this Embodiment 2, and the configuration of ceiling frame portions configured with these connecting members as eaves receivers, FIG. 19 is an enlarged perspective view of a main part as seen from the connecting member side (ceiling frame side) showing the configuration of a pair of left and right partition walls and connecting members connecting these partition walls to each other in the partition ceiling, and the configuration of ceiling frame portions configured with these connecting members as eaves receivers, FIG. 20 is an enlarged front view of a main part at one end side of the connecting member showing the configuration of the connecting member connecting a pair of left and right partition walls to each other in the partition ceiling and the ceiling frame portion configured with this connecting member as an eaves receiver, FIG. 21 is an enlarged bottom view of a main part at one end side of the connecting member showing the configuration of the connecting member connecting a pair of left and right partition walls to each other in the partition ceiling and the ceiling frame portion configured with this connecting member as an eaves receiver, and FIG. 22 is an enlarged perspective view showing the configuration of a modified example in which the eaves connecting metal fitting used for connecting the connecting member constituting the eaves receiver of the ceiling frame and the eaves in the partition ceiling is changed from a double clip type orthogonal clip to a single clip type orthogonal clip.

[0088] The partition ceiling according to Embodiment 2 of this invention is characterized in that the square studs 12, 12... in the partition base of the partition ceiling according to Embodiment 1 are changed to channel members (grooved steel with lips) 12, 12... having lip portions, and the overall shape of the through holes 12a to 12c of the anti-sway members 13, 13... is made into a mountain shape, and the upper part of the anti-sway members 13, 13... having a channel structure inserted and fitted with the flange portion side to the lower end 12a portion of the through hole with a small opening diameter is fixed by a spacer 17 via a pressing piece 16.

[0089] In the second embodiment, for example, as shown in FIGS. 15 to 20, when attaching the edge members 32, 32,... to the connecting members 31, 31,... which are the edge receivers, the double clip type orthogonal clips 33, 33,... described above are used, but all of these can be changed to, for example, the single type orthogonal clips 33, 33,... shown in FIG. 22.

[0090] All other configurations are the same as those of the partition ceiling according to the first embodiment described above, and the same operations and effects can be achieved.

[0091] In this way, even when the square studs 12, 12,... constituting the partition base are changed to channel members having a lip portion, for example, light channel steel with a lip, in exactly the same manner as in the first embodiment, a pair of left and right partition walls 1, 1 can be connected and integrated into a portal (H-shaped) by the connecting members 31, 31,... made of a plurality of square steel pipes. Therefore, the same operations and effects as in the first embodiment can be achieved.

[0092] <Regarding the configuration of the partition ceiling according to the third embodiment of the present invention: FIGS. 23 to 26> FIGS. 23 to 26 show the configuration of the main part of the partition ceiling according to the third embodiment of the present invention installed using the partition base. FIG. 23 is an enlarged front view of the main part showing the configuration of a pair of left and right partition walls and the connecting members connecting these partition walls, and the configuration of the ceiling frame parts formed by using the connecting members as edge receivers. FIG. 24 is an enlarged perspective view of the main part seen from the partition wall side (partition base side) showing the configuration of a pair of left and right partition walls and the connecting members connecting these partition walls, and the configuration of the ceiling frame parts formed by using the connecting members as edge receivers. FIG. 25 is an enlarged perspective view of the main part seen from the connecting member side (ceiling frame side) showing the configuration of a pair of left and right partition walls and the connecting members connecting these partition walls, and the configuration of the ceiling frame parts formed by using the connecting members as edge receivers. FIG. 26 is an enlarged perspective view showing the configuration of the mounting bracket (clip) for attaching the edge to the connecting member which is the edge receiver in the partition ceiling.

[0093] The partition ceiling according to Embodiment 3 of the present invention changes the square studs 12, 12... in the partition base of the partition ceiling according to Embodiment 1 above to channel members 12, 12... having a lip portion, and the overall shape of the through-holes 12a to 12c of the anti-sway members 13, 13... is made into a mountain shape, and the upper part of the inserted anti-sway member 13, 13... of the channel structure is fixed by a spacer 17, and a plurality of connecting members 31, 31... for connecting the pair of left and right partition walls 1, 1 to each other are changed from the above-mentioned square steel pipes to lip groove-shaped steel. Other configurations are the same as those of the partition ceiling according to Embodiment 1 above, and the same operations and effects can be achieved.

[0094] In this way, even when the square studs 12, 12... constituting the partition base are changed to channel members having a lip portion, for example, light channel steel with a lip, and a plurality of connecting members 31, 31... for connecting the pair of left and right partition walls 1, 1 to each other are changed from the above-mentioned square steel pipes to lip groove-shaped steel, similar to the case of Embodiment 1 above, a pair of left and right partition walls 1, 1 can be connected and integrated into a portal (H-shaped) by the plurality of connecting members 31, 31... made of lip groove-shaped steel, and its strength can be improved. Therefore, the same operations and effects as in the case of Embodiment 1 above can be achieved.

[0095] In the case of such a configuration, although both are inferior in strength to the square studs and square steel pipes respectively, both have a lip portion and have a cross-sectional strength close to that of the square studs and square steel pipes. Therefore, the strength and rigidity of the partition base and the connecting members 31, 31... are effectively improved, and the ceiling frame support strength of the ceiling frame support portion composed of the portal structure (H-shaped structure) and the seismic resistance strength of the building structure are effectively improved. Also, compared with the square studs and square steel pipes, there is a relatively merit in that weight reduction and cost reduction can be achieved relatively.

[0096] In the case of this embodiment, the clip 34 for attaching the edge 32 to the connecting member 31 which is an edge receiver, for example as shown in Fig. 26, the structure of the connecting portion 34b with the lower edge 32 is the same as that of the orthogonal clips 33, 33 in Figs. 11 and 12 described above. On the other hand, the hook portion 34a on the upper end side has a flat cross-sectional U-shaped structure that appropriately engages with the lower lip portion of the lip groove-shaped steel. And screw holes 34c, 34d, 34d similar to the orthogonal clips 33, 33 are provided in these respective portions.

[0097] Also, in the same configuration, one side wall portion 21a of the connecting and fixing fitting 2 is also connected using the upper and lower lip portions of the connecting member 31 made of lip groove-shaped steel (the other side uses the web portion). Therefore, it is possible to maintain a connection strength substantially the same as that of a square steel pipe (refer to the connection states in Figs. 23 to 25).

[0098] Also, in the above description, a plurality of studs 12, 12·· of the groove type with lips have been described, but it is also possible to change this to studs of the square type as in Embodiment 1.

[0099] <Configuration of the partition ceiling according to Embodiment 4 of the present invention: Figs. 27 to 33> Next, Figs. 27 to 33 show the configuration of the partition ceiling according to Embodiment 4 of the present invention installed using a partition base.

[0100] FIG. 27 is a perspective view of the entire predetermined length portion of the partition ceiling, FIG. 28 is a front view of the entire predetermined length portion of the partition ceiling, FIG. 29 is an enlarged front view showing the connection portion between the partition wall and the connecting member of the partition ceiling and the structure of the ceiling frame suspension portion, FIG. 30 is an enlarged perspective view showing the engagement structure of the upper end of the suspension bolt for suspending the ceiling frame with respect to the connecting member of the partition ceiling, FIG. 31 is an enlarged perspective view showing the structure of the engaging member (upper side hook portion) at the engaging portion of the upper end of the suspension bolt for suspending the ceiling frame with respect to the connecting member of the partition ceiling, FIG. 32 is an enlarged perspective view showing the engagement structure of the lower end of the suspension bolt for suspending the ceiling frame with respect to the edge of the partition ceiling, and FIG. 33 is an enlarged perspective view showing the attachment state of the edge to the edge receiver of the partition ceiling.

[0101] In the configuration of this Embodiment 4, similar to the case of the above-described Embodiment 1, a plurality of connecting members 36, 36... for connecting the pair of left and right partition walls 1, 1 to each other use the same square steel pipe. However, in the case of this embodiment, instead of directly connecting the edges 32, 32... to the connecting members 36, 36..., suspension bolts 38, 38... of a predetermined length are used to suspend the ceiling frame 3 composed of edge receivers 35, 35... and edges 32, 32... at a predetermined height for installation.

[0102] Also in this case, the above-described connecting and fixing fittings 2, 2... are used for connecting the pair of left and right partition walls 1, 1 and the plurality of connecting members 36, 36..., and they are connected and fixed in a manner spanning between the pair of left and right partition walls 1, 1 in exactly the same way. The configurations of the pair of left and right partition walls 1, 1 are also exactly the same. Therefore, it is also exactly the same that the wall surface strength of the pair of left and right partition walls 1, 1 themselves is improved, and they are connected and integrated into a portal structure (H-shaped structure) by a plurality of connecting members 36, 36..., thereby improving the ceiling frame support strength and seismic resistance.

[0103] However, in the case of this embodiment, as shown in FIG. 33, the ceiling frame 3 is configured as a normal ceiling frame, and is composed of edge receivers 35, 35... and edges 32, 32... both made of channel-shaped steel (C-shaped steel) with a channel structure, and is integrally connected by orthogonal clips 41, 41... and 42, 42... The edge receiver 35, 35... portion of the ceiling frame 3 having the same configuration is suspended by a first hanger 37 on the upper side and a second hanger 39 on the lower side via suspension bolts 38, 38... having a predetermined length.

[0104] The first hanger 37 on the upper side, for example, as shown in FIGS. 30 and 31, has a hook-shaped hook member body 37a that is open downward, a screw hole 37c for screwing to a connecting member 31 provided on the side wall of the hook-shaped hook member body 37a, a suspension bolt engaging piece 37b formed by bending the lower end side of the same side wall in the horizontal direction, and a nut member 37d that screw-engages and locks the upper end side of the suspension bolt 38 provided at the suspension bolt engaging piece 37b portion in a height-adjustable state. And the side wall portion of the hook member body 37a is screwed and fastened to the connecting member 31 by a predetermined screw 37e through the screw hole 37c and fixed, for example, as shown in FIG. 30. Then, after that, the upper end side screw portion of the suspension bolt 38 is screwed into the nut member 37d to suspend the suspension bolt 38 at a predetermined length.

[0105] On the other hand, on the lower end side of the same suspension bolt 38, for example, as shown in FIG. 32, the second hanger 39 on the lower side is screw-engaged, and the edge receiver 35 portion of the ceiling frame 3 is engaged through the second hanger 39. As shown in the figure, this second hanger 39 has a hook-shaped hook member body 39a that is open upward, opposite to the first hanger 37, a suspension bolt engaging piece 39b formed by bending the upper end side of the side wall portion of the hook member body 39a in the horizontal direction, and a nut member 39c that screw-engages and locks the lower end side of the suspension bolt 38 provided at the suspension bolt engaging piece 39b portion in a height-adjustable state. And the suspension bolt engaging piece 39b portion is screw-engaged with the lower end of the suspension bolt 38 having a screw portion by the nut member 39c.

[0106] Then, using the first and second hangers 37 and 39 and the suspension bolts 38, the ceiling frame 3 (see FIG. 33) composed of the soffit supports 35, 35... and the soffits 32, 32... is suspended at a desired height as shown in FIG. 29, for example.

[0107] In the case of such a configuration, even in the case of, for example, a hospital corridor, or when the depth of the ceiling is specifically deeper than a predetermined level, while sufficiently ensuring the strength of the portal structure (H-shaped structure) by the connecting members 31, 31... described above, it becomes possible to realize a suspended ceiling structure using suspension bolts (short) 38, 38... according to the case. And in the case of this embodiment, even if it is a suspended ceiling structure, since the lengths of the suspension bolts 38, 38... are short enough, the possibility of restricting the installation space for equipment, piping, etc. is small. In addition, since the strength of the connecting members 31, 31... as the crossbeam structure for connecting the pair of left and right partition walls 1, 1 to each other is sufficiently high, the suspension strength and seismic resistance of the ceiling frame 3 can be sufficiently ensured.

[0108] Note that the soffits 32, 32... constituting the ceiling frame 3 include a double type with a large web width and a single type with a narrow web width. Therefore, when actually attaching the soffits 32, 32..., for example, as shown in FIG. 29, according to the dimensions of those soffits 32, 32..., either a double type clip 41 or a single type clip 42 for attachment is properly used.

[0109] <Configuration of the partition ceiling according to Embodiment 5 of the present invention: FIGS. 34 to 36> Next, FIGS. 34 to 36 show the configuration of the partition ceiling according to Embodiment 5 of the present invention installed using the partition base.

[0110] Fig. 34 is an enlarged front view showing the connection part between the partition wall and the connecting member of the partition ceiling and the structure of the ceiling frame suspension part, Fig. 35 is an enlarged perspective view showing the engagement structure of the upper end of the suspension bolt for suspending the ceiling frame with respect to the connecting member of the partition ceiling, and Fig. 36 is an enlarged perspective view showing the engagement structure of the lower end of the suspension bolt for suspending the ceiling frame with respect to the edge receiver on the ceiling frame side of the partition ceiling.

[0111] The structure of the partition ceiling according to this Embodiment 5 is configured to suspend the ceiling frame 3 by using a plurality of connecting members 36, 36... that connect a pair of left and right partition walls 1, 1 to each other, as shown in Fig. 34, for example, in the same manner as in the case of the above Embodiment 4. However, instead of the square steel pipes as in the above Embodiment 4, a plurality of connecting members 36, 36... that serve as cross beam members for connecting a pair of left and right partition walls 1, 1 to each other and suspending the ceiling frame 3 use, for example, a lip groove-shaped steel (groove-shaped steel with a lip) provided with a lip portion on the open end side of each flange portion, as shown in Fig. 35.

[0112] Correspondingly, the structure of the first hanger 46 on the upper end side of the suspension bolt 38 is changed to a structure suitable for engaging with the lip portion of the lip groove-shaped steel. That is, the first hanger 46 is composed of an inverted V-shaped hook piece 46a that engages with the lip portion of the connecting member 36 made of lip groove-shaped steel and a horizontal engaging piece 46b provided with a nut portion 46c that engages with the upper end of the suspension bolt 38 in a screwed state. On the other hand, on the lower end side of the suspension bolt 38, the second hanger 47 on the lower end side that engages with the edge receiver 35 of the ceiling frame 3 is composed of a U-shaped hook piece 47a that engages with the edge receiver 35 of the ceiling frame 3 from below and a horizontal engaging piece 47b provided with a nut portion 47c that engages with the lower end of the suspension bolt 38 in a screwed state.

[0113] The structure of the other parts is basically the same as the structure of the above Embodiment 4.

[0114] <Regarding the structure of the partition ceiling according to Embodiment 6 of the present invention: Figs. 37 and 38> Next, FIGS. 37 and 38 show the configuration of the main part of the partition ceiling according to Embodiment 6 of the present invention installed using a partition base.

[0115] The partition ceiling according to Embodiment 6 is characterized in that, in the partition ceiling according to Embodiment 4 using connecting members 36, 36,... made of square steel pipes, the structure of the first hanger on the upper end side of the suspension bolt 38 is changed. The configuration of other parts is the same as that of Embodiment 4.

[0116] That is, as shown in FIGS. 37 and 38, the first hanger 50 on the upper end side of the suspension bolt 38 in this embodiment includes a fitting piece body having a U-shaped cross-section that is fitted into the connecting member 36 from the side, and a bolt insertion groove portion interposed between the upper end portion of the upper piece 50a and the lower end portion of the lower piece 50b of the fitting piece body. It consists of a connecting support member 50c having a hat-shaped cross-section, and nuts 50d, 50d for screwing the upper end portion of the suspension bolt 38, which are integrally provided on the upper surface side of the end portion of the upper piece 50a and the lower surface side of the end portion of the lower piece 50b of the fitting piece body, respectively.

[0117] The upper and lower ends of the flange portion along the side wall portion of the connecting member 36 of the connecting support member 50c having a hat-shaped cross-section are bent at right angles to the upper and lower surfaces of the connecting member 36 so as to engage with the connecting member 36 in a U-shaped cross-section. As a result, the fitting piece body having a U-shaped cross-section and the connecting support member 50c having a hat-shaped cross-section are both set so as to face each other and wrap the connecting member 36 (in a state where the positions of the bolt insertion groove of the connecting support member 50c and the screwing holes of the nuts 50d, 50d of the upper piece 50a and the lower piece 50b of the fitting piece body are aligned).

[0118] Then, in the same set state, the connecting support member 50c is fixed to the side wall surface of the connecting member 36 with screws 51, 51. Then, as shown in the figure, the upper end side of the suspension bolt 38 is inserted and screwed upward from below by a predetermined dimension and securely fixed by two sets of upper and lower nuts 50d, 50d.

[0119] With such a configuration, the upper end of the suspension bolt 38 can be securely and firmly connected to the entire circumferential surface of the connecting bolt 36 by the first hanger 50, enabling more stable suspension of the ceiling frame 3. As a result, the seismic performance is also improved.

[0120] <Configuration of the partition ceiling according to Embodiment 7 of the present invention: FIGS. 39 and 40> Next, FIGS. 39 and 40 show the configurations of two types of orthogonal clips (single type, double type) in the partition ceiling according to Embodiment 7 of the present invention installed using the same partition base as in Embodiment 1 above.

[0121] The orthogonal clip (single type) 33 in FIG. 39 and the orthogonal clip 33 (double type) in FIG. 40 used in the partition ceiling according to this Embodiment 7 respectively correspond to the orthogonal clip (single type) 33 in FIG. 11 and the orthogonal clip 33 (double type) in FIG. 12 used in the partition ceiling according to Embodiment 1 above. However, in the orthogonal clip (single type) 33 in FIG. 39 and the orthogonal clip 33 (double type) in FIG. 40 of this embodiment, on the engaging portion 33a of the hook structure to the connecting member 31 made of square steel pipe from the top surface portion through the side contact surface to the mounting portion 33b of the edge 32 across the entire top surface portion, reinforcing bead portions 33g, 33g are provided in a state of being continuous with each other on both the left and right sides thereof. The configurations of the other parts are the same as those of Embodiment 1 above.

[0122] According to such a configuration, the strength of the orthogonal clips (single type and double type) 33, 33 for attaching the edge 32 to the high-strength connecting member 31 connected to the pair of left and right partition walls 1, 1 via the connecting and fixing fittings (end fixing fittings) 2, 2·· itself is effectively improved, and the attachment strength of the edge 32 to the high-strength connecting member 31 is further effectively improved.

[0123] Incidentally, the beaded orthogonal clip (double type) 33 with the configuration shown in FIG. 40 in this embodiment can also be used in place of the beadless orthogonal clip (double type) 33 in the second embodiment.

[0124] <Regarding the configuration of the partition ceiling according to Embodiment 8 of the present invention: FIG. 41> Next, FIG. 41 shows the configuration of the orthogonal clip (single type) in the partition ceiling according to Embodiment 8 of the present invention installed using the same partition base as in the second embodiment.

[0125] The orthogonal clip (single type) 33 in FIG. 41 in this embodiment is configured in place of the orthogonal clip 33 (single type) in FIG. 22 in the second embodiment. Similar to the orthogonal clip (single type) 33 in FIG. 39 in the seventh embodiment, the engaging portion 33a of the hook structure engaged with the connecting member 31 extends from the top surface portion through the side contact surface to the mounting portion 33b of the edge 32 on the top surface, and the reinforcing bead portions 33g, 33g are provided continuously on both the left and right sides thereof. The configuration of other parts is the same as that of the second embodiment.

[0126] According to such a configuration, the strength of the orthogonal clip (single type) 33 itself for attaching the edge 32 to the connecting member 31 is effectively improved, and the attachment strength of the edge 32 to the connecting member 31 made of a high-strength square steel pipe is also effectively improved.

[0127] <Regarding the configuration of the partition ceiling according to Embodiment 9 of the present invention: FIGS. 42 to 48> Next, FIGS. 42 to 48 show the configuration of the partition ceiling according to Embodiment 9 of the present invention installed using the same partition base as in the first embodiment.

[0128] First, Fig. 42 is a perspective view showing the overall configuration of the partition ceiling installed with a wall structure using a pair of left and right partition walls. Fig. 43 is a front view showing the overall configuration of the partition ceiling. Fig. 44 is a bottom view showing the overall configuration of the partition ceiling. Fig. 45 is an enlarged front view of the main part on one end side (left end side) of the connecting member showing the configuration of the connecting member that connects a pair of left and right partition walls to each other in the partition ceiling and the ceiling frame part configured with the connecting member as a field edge receiver. Fig. 46 is an enlarged perspective view of the main part seen from above of the side of the connecting member (ceiling frame side) showing the configuration of a pair of left and right partition walls in the partition ceiling, the connecting member that connects these partition walls to each other, and the ceiling frame parts configured with the connecting member as a field edge receiver. Fig. 47 is a perspective view seen from the lower side of Fig. 46 showing the attachment structure of the field edge where the connecting member that connects a pair of left and right partition walls to each other in the partition ceiling is attached as a field edge receiver. Fig. 48 is a bottom view seen from the lower side of Fig. 46 showing the attachment structure of the field edge where the connecting member that connects a pair of left and right partition walls to each other in the partition ceiling is attached as a field edge receiver.

[0129] As described above, in the case of the configuration of the first embodiment, the field edge 32 is also attached to the lower surface portion of the connecting end portion 31a of the connecting member 31 connected and fixed to the connecting and fixing fitting 2. However, since there are side plates 21a, 21a of the connecting and fixing fitting 2 with a thick plate thickness on the left and right of this portion, orthogonal clips 33, 33 as shown in Figs. 11, 12, 39, and 40 cannot be used (there are also reinforcing ribs 21f, 21f and the dimensions do not match). Moreover, the field edge 32 is a square steel pipe and its entire body has a closed cross-section.

[0130] Therefore, in this portion, as shown in Figs. 4 and 5, a large-diameter hole (reference numeral omitted: see Fig. 5) for screwing is drilled on the lower surface side of the field edge 32 made of the square steel pipe with a hole saw, and the upper surface side is screwed to the lower surface of the central portion in the width direction of the connecting side end portion 31a of the connecting member 31 made of the square steel pipe through the large-diameter hole using a screw 21m. In this case, preferably, a small-diameter pilot hole is drilled on the upper surface side.

[0131] In this embodiment, the same screw-fastening structure is applied not only to the edge 32 at the lower part of the connecting and fixing fitting 2 as described above, but also to all the edges 32, 32... attached across both ends of the connecting member 31. The configurations of the other parts are the same as those in the first embodiment.

[0132] That is, in the case of the edges 32, 32... made of square steel pipes in this embodiment, as shown in FIGS. 47 and 48, large-diameter holes 32b, 32b... for screw-fastening are drilled on the lower surface side with a hole saw, while small-diameter lower holes 32a, 32a... for screw threads are drilled on the upper surface side. Then, after aligning the coaxial large-diameter holes 32b, 32b... and small-diameter lower holes 32a, 32a... of those edges 32, 32... with the center of the lower surface of the connecting member 31 respectively, screws 21m, 21m... are screwed in from the lower side to fasten and fix them.

[0133] As a result, a neat partition ceiling base, such as that shown in FIGS. 42 to 46, without any of the orthogonal clips 33, 33... as described above, is realized.

[0134] In the case of such a configuration, a large number of orthogonal clips 33, 33... become unnecessary, and the component cost is greatly reduced. Also, the installation work becomes very simple. There are many advantages such as the structure of the ceiling frame part being simplified and the weight being reduced.

[0135] Regarding the mounting strength of the ceiling board 4 as well, as described above, since the strength of the connecting member 31 part made of square steel pipes is very high, and the edges 32, 32... themselves are also made of square steel pipes and have very high strength, by using screws 21m, 21m... with sufficient strength, a structure with sufficient strength can be realized. In particular, in the case of the same configuration, the strength of the mounting part is common in all 360-degree directions, which is also advantageous in that there are no weak points.

[0136] In addition, in the same configuration, in addition to the same configuration, predetermined parts, for example, the above-mentioned orthogonal clips (single type and double type) 33, 33... can be arbitrarily provided at positions separated by a predetermined interval to further improve the attachment strength.

[0137] <Regarding the structure of the partition ceiling according to Embodiment 10 of the present invention: FIGS. 49 to 50> Next, FIGS. 49 to 50 show the structure of the partition ceiling according to Embodiment 10 of the present invention installed using the same partition base (grooved steel with a lip on the stud 12, square steel pipe on the connecting member 31) as in the above Embodiment 2.

[0138] And, in the partition ceiling of the same configuration, it is characterized in that the attachment structure of the edge frames 32, 32... made of square steel pipes, which is exactly the same as that in the above Embodiment 9, is adopted for the connecting member 31 made of square steel pipe. All other configurations are the same as those in the above Embodiment 2.

[0139] Even in such a configuration, the same operational effects as those in the above Embodiment 9 can be achieved.

[0140] <Regarding the structure of the partition ceiling according to Embodiment 11 of the present invention: FIGS. 51 to 52> Next, FIGS. 51 to 52 show the structure of the partition ceiling according to Embodiment 11 of the present invention installed using the same partition base (channel member with a lip portion on the stud 12, lip grooved steel on the connecting member 31) as in the above Embodiment 3.

[0141] And, in the partition ceiling of the same configuration, it is characterized in that the attachment structure of the edge frames 32, 32... made of square steel pipes, which is exactly the same as that in the above Embodiment 9, is adopted for the connecting member 31 made of lip grooved steel. All other configurations are the same as those in the above Embodiment 3.

[0142] Even in such a configuration, the same operational effects as those in the above Embodiment 9 can be achieved.

[0143] <Configuration of the partition ceiling according to Embodiment 12 of the present invention: FIGS. 53 to 54> Next, FIGS. 53 to 54 show the configuration of the partition ceiling according to Embodiment 12 of the present invention, which is installed using the same partition base (square steel pipes for the studs 12 and square steel pipes for the connecting members 31) as in Embodiment 1 above.

[0144] In the configuration of this embodiment, for example, as shown in FIGS. 53 to 54, instead of the single gypsum board 15 in Embodiment 1 above, two gypsum boards 15a and 15b, namely the first and the second, are used, and the attachment structure of the edge strips 32, 32... similar to that in Embodiment 9 above is adopted.

[0145] In the case of this embodiment, the galvanized steel plate 14 is directly screwed to the studs 12, 12, and two gypsum boards 15a and 15b, namely the first and the second, are provided behind it, and the connecting fitting (end fixing fitting) 2 is screwed to the galvanized steel plate 14 via the two gypsum boards 15a and 15b. In the figure, 21p is the screw for fixing the galvanized steel plate 14 to the stud 12, and 21k is the screw for fixing the connecting fitting (end fixing fitting) 2 to the galvanized steel plate 14.

[0146] Thus, when adopting the configuration of stacking two gypsum boards 15a and 15b, namely the first and the second, as the gypsum board part, the plate thickness of the gypsum board part for fixing the connecting and fixing fitting (end fixing fitting) 2 to the galvanized steel plate 14 becomes thicker (12.5 mm × 2 = 25 mm), and the screwing operation of the connecting and fixing fitting (end fixing fitting) 2 to the galvanized steel plate 14 on the stud 12 side becomes easy and stable.

[0147] On the other hand, when the gypsum board part is configured by overlapping a plurality of gypsum boards in this way, the thickness of the gypsum board part increases, and the problems in the installation of the connecting and fixing fitting 2 described in the part of Modification 1 of Embodiment 1 above also increase.

[0148] Therefore, when adopting a structure in which a plurality of gypsum boards are laminated as described above, if necessary, use a galvanized steel plate 6 for attaching the connecting and fixing fitting 2 similar to the first modification of the first embodiment described above to attach the connecting and fixing fitting 2. By doing so, when a plurality of gypsum boards are laminated to achieve ease and stability in the attachment work, it is possible to simultaneously achieve stable attachment strength and durability of the attached connecting and fixing fitting 2.

[0149] Note that the configuration in which the gypsum board portion is composed of a plurality of gypsum boards can be similarly adopted when the connecting member 31 portion is a square steel pipe and the stud 12, 12 portions are channel members with a lip portion, and also when the connecting member 31 portion is a lip groove-shaped steel and the stud 12, 12 portions are channel members with a lip portion.

[0150] <Configuration of the partition ceiling according to the thirteenth embodiment of the present invention: FIGS. 55 to 56> Next, FIGS. 55 to 56 show the configuration of the partition ceiling according to the thirteenth embodiment of the present invention installed using a partition base (square steel pipes for the studs 12 and square steel pipes for the connecting members 31) similar to that of the first embodiment described above.

[0151] In the configuration of this embodiment, for example, as shown in FIGS. 55 to 56, instead of the single gypsum board 15 in the first embodiment, two gypsum boards 15a and 15b, the first and the second, are used, and the attachment structure of the edge strips 32, 32... similar to that of the ninth embodiment described above is adopted.

[0152] In the case of this embodiment, the galvanized steel plate 14 is screwed to the studs 12, 12 via the first gypsum board 15a, and behind it, two second gypsum boards 15b are provided, and a connecting fitting (end fixing fitting) 2 is screwed to the galvanized steel plate 14 via the second gypsum board 15b. In the figure, 21p is a screw for fixing the galvanized steel plate 14 to the stud 12, and 21k is a screw for fixing the connecting fitting (end fixing fitting) 2 to the galvanized steel plate 14.

[0153] When adopting the configuration in which two gypsum boards 15a and 15b of the first and second are stacked in this way, similar to the case of the above-described Embodiment 12, the plate thickness of the gypsum board portion for fixing the connecting and fixing fitting (end fixing fitting) 2 to the galvanized steel plate 14 becomes thick (12.5 mm × 2 = 25 mm), and the screw fastening work of the connecting and fixing fitting (end fixing fitting) 2 to the galvanized steel plate 14 becomes easy and stable.

[0154]

[0153] Moreover, in the case of this embodiment, different from the configuration of the above-described Embodiment 12, the galvanized steel plate 14 serving as the mounting substrate of the connecting and fixing fitting (end fixing fitting) 2 is positioned and arranged in the middle of the two gypsum boards 15a and 15b of the first and second. Therefore, although the overall thickness of the gypsum board portion does not change, the galvanized steel plate 14, which is the direct mounting substrate, corresponds to the connecting and fixing fitting (end fixing fitting) 2 only through the second gypsum board 15b (one sheet).

[0155] Therefore, while maintaining the easiness and stability of the screw fastening work similar to the case of the above-described Embodiment 12, a relatively high connecting strength can be realized as compared with the above-described Embodiment 12. As a result, in the case of the same configuration, even when attaching a handrail or the like to the partition wall 1, 1 portion, it can be made easy to attach.

[0156] When the gypsum board portion is configured by a plurality of gypsum boards with the galvanized steel plate 14 sandwiched therebetween in this way, although there is one gypsum board between the galvanized steel plate 14 and the connecting and fixing fitting 2, problems in the attachment of the connecting and fixing fitting 2 still occur in the same way as in the case described in the partial modification example 1 of the above-described Embodiment 1.

[0157] Therefore, even when adopting the same configuration, if necessary, the zinc-plated steel plate 6 for attaching the connecting and fixing fitting 2 similar to the first modification of the above-described Embodiment 1 is used to attach the connecting and fixing fitting 2. By doing so, when two gypsum boards are superposed as a whole to achieve ease and stability in the attachment work, it is possible to simultaneously achieve stable attachment strength and durability of the attached connecting and fixing fitting 2.

[0158] In this case, since there is one gypsum board between the stud 12 and the zinc-plated steel plate 14 and one gypsum board between the zinc-plated steel plate 14 on the stud 12 side and the zinc-plated steel plate 6 on the connecting and fixing fitting 2 side, even if it is said that they are connected via the gypsum board, the connection strength between the stud 12 and the zinc-plated steel plate 14 and between the zinc-plated steel plate 14 and the zinc-plated steel plate 6 (connecting and fixing fitting 2) is maintained at a sufficiently high level.

[0159] Note that the configuration in which the gypsum board portion is composed of a plurality of gypsum boards and the zinc-plated steel plate 14 is interposed therebetween can be similarly adopted even when the connecting member 31 portion is a square steel pipe and the stud 12, 12 portions are channel members provided with a lip portion, and also when the connecting member 31 portion is a lip groove-shaped steel and the stud 12, 12 portions are channel members provided with a lip portion.
