Description

[Technical Field]

[0001] The present invention relates to a ceiling structure that uses simple components (ceiling materials and retaining components) and that can be installed extremely easily. [Background technology]

[0002] A roof structure in which a tight frame is fixed to a cross beam (body) made of a steel frame and folded plates are laid on the tight frame is widely known. In this type of roof structure, the folded plates are laid perpendicular to the longitudinal direction of the cross beams. Furthermore, because the cross beams are constructed at intervals of 3 to 5 meters due to the shape of the roof material, etc., space is required to set up scaffolding inside the building when installing the tight frame and laying the roof material. In this case, the ceiling structure is generally constructed separately from the roof structure. Therefore, if you try to install a ceiling in a gymnasium or similar building after installing a roof, scaffolding is required just for the ceiling installation.

[0003] For example, Patent Document 1 proposes a structure in which a vertically long exterior material holding member 4 is fixed to an upper flange 21 of a structural member 2, and a decorative member 3 is installed between the structural members 2, 2. Furthermore, Patent Document 2 proposes a structure in which a support for attaching the side edge of a ceiling material and a support for attaching an exterior material are fixed in a two-story manner at approximately the same position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-19557 [Patent Document 2] Patent No. 5973749 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned Patent Document 1, for example, a vertically elongated exterior material holding member 4 is required, and in the above-mentioned Patent Document 2, a two-story fixed support is required, even though these are both complex components. In addition, because the connection positions of the exterior material and the ceiling material are connected vertically, there is also the problem that construction is extremely difficult.

[0006] Therefore, an object of the present invention is to propose a ceiling structure that uses simple components (retaining components and ceiling materials) and that can be installed extremely easily. [Means for solving the problem]

[0007] The present invention has been proposed in view of the above, and is a ceiling material comprising: a holding member having a horizontal support base portion; rising portions that rise upward on the left and right sides of a face plate portion; support surface portions that extend outward from the upper ends of the rising portions and are placed on the support base portions; and folded-down portions where the tips of the support surface portions are folded down. Using The support surface portions of the ceiling materials adjacent to each other on the left and right sides of the holding member are connected in an overlapping manner on the support base portion of the holding member, Applicable Support surface part On the top side of This relates to a ceiling structure characterized by having a roof structure installed.

[0008] The present invention also proposes a ceiling structure as described above, characterized in that the face plate portion of the ceiling material is porous. [Effects of the Invention]

[0009] The ceiling structure of the present invention is A structure including a roof structure,The ceiling material and the holding member used are extremely simple, and the support surface parts formed on the adjacent ceiling materials on either side of the holding member are simply connected to the support base part of the holding member in an overlapping state, so construction can be easily carried out from the roof side, for example, and this has extremely high practical value. In particular, since construction can be carried out from the roof side, no scaffolding is required on the indoor side, so there is no need for a huge space for scaffolding or huge costs for scaffolding construction. In addition, the ceiling Material construction Since there is no restriction on the roof structure, it can be easily applied to the direction along the flow direction and the direction perpendicular to the flow direction, and can be easily applied to various roof structures. Moreover, the support of the ceiling material surface Department Top side of The roof structure is constructed on the roof, so the direction of the ceiling material is determined appropriately according to the slope of the base, etc. Material construction There are no restrictions on the type of roofing, so you can choose either vertical or horizontal roofing as appropriate.

[0010] Furthermore, if the panel portion of the ceiling material is porous, that portion (panel portion) can be formed, for example, from punched metal, which means that it is possible to either use insulating material or functional material or not, and it also takes into consideration sound absorption, light weight, etc. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] The ceiling structure of the present invention is a ceiling material comprising: a holding member having a horizontal support base portion; rising portions that rise upward on the left and right sides of a face plate portion; support surface portions that extend outward from the upper ends of the rising portions and are placed on the support base portions; and folded-down portions where the tips of the support surface portions are folded down. Using The support surface portions of the ceiling materials adjacent to each other on the left and right sides of the holding member are connected in an overlapping manner on the support base portion of the holding member, Applicable Support surface part On the top side of It is characterized by the construction of a roof structure.

[0013] The holding member used in the ceiling structure has a horizontal support base as described above, and preferably has legs and fixing parts that extend horizontally from the lower ends of the legs as in the illustrated embodiment described below. This holding member may be of approximately the same length as the ceiling material, or may be in the form of pieces. The size (width) of the support base is not limited, and it is sufficient if it can be fitted with fixing devices such as screws while the support surface of the adjacent ceiling material is placed on it. Therefore, as the holding member, a steel section such as a C-shaped steel may be used as shown in the illustrated embodiment described later, or a plate-shaped material may be bent appropriately and used.

[0014] In addition, various types of roof structures can be constructed above the ceiling structure as appropriate, but in principle there are no restrictions on these ceiling and roof structures, so there are no restrictions on their respective structures, installation types, or installation methods. In the illustrated embodiment of the present invention shown in Figures 3 and 4 described below, the roof structure is constructed using the portion where the support surfaces of the ceiling material are connected together in an overlapping manner on the support base portion of the retaining member as the mounting base surface.

[0015] Furthermore, the base (main body) to which this retaining member is fixed is a cross beam in the illustrated embodiment described below, but this is not particularly limited, and the fixing portion can be aligned along the base and fixed with an appropriate fixing device.

[0016] The ceiling material used in the ceiling structure comprises, as described above, a face plate portion, and on the left and right sides thereof, rising portions that rise upward, a support surface portion that extends from the upper end of the rising portion toward the support base portion and is placed on the support base portion, and a folded-down portion where the tip of the support surface portion is folded down. Note that, since this ceiling material is one of the interior materials, unlike the roof structure, it is a member that essentially forms a flat ceiling surface, and its arrangement direction may be either along the flow direction of the roof slope or perpendicular to the flow direction.

[0017] The face plate portion is a portion that forms the ceiling surface and may be flat or corrugated, and may have a heat insulating material or various functional materials disposed on its upper surface. Alternatively, it may be a porous face plate having many holes, in which case the face plate portion may be formed of, for example, punched metal, and may or may not have a heat insulating material or various functional materials disposed thereon, but should be designed with consideration given to sound absorption, light weight, etc.

[0018] The raised portions are portions where the left and right sides of the face plate portion are raised upward, and may be substantially vertical or inclined, or may have an appropriate engaging portion formed near the base end. This engaging portion may be a portion that engages with a holding member, or may be a portion that protrudes inward in a V-shape to attach a decorative material, a hanging metal fitting, or the like.

[0019] The support surface portion extends outward from the upper end of the rising portion and is placed on the support base portion of the retaining member, and is also the point where adjacent ceiling materials are connected in a superimposed manner, so mounting holes for driving in fixing devices may be formed in advance. This support surface portion is placed on top of the support base portion of the holding member, so if one of the left and right sides is located lower and the other is located upper, the lower support surface portion should be formed slightly larger than the width of the support base portion, and the upper support surface portion should be formed larger than that (the width of the lower support surface portion).

[0020] The folded-down portion is the area where the tip of the support surface portion is folded down, and there is no particular limitation on its length (folded-down length), but if, as mentioned above, one of the left and right support surface portions is located lower and the other support surface portion is located upper, the folded-down portion where the tip of the lower support surface portion is folded down is folded down so as to follow the inner surface side of the rising portion, and there is no such limitation on the folded-down portion where the tip of the upper support surface portion is folded down.

[0021] The ceiling structure of the present invention uses extremely simple ceiling materials and holding members, and simply connects the support surface portions formed on adjacent ceiling materials on the left and right sides to the support base portion of the holding member in an overlapping manner, so construction can be easily carried out even from the roof side, making it of extremely high practical value. In particular, since construction can be carried out from the roof side, no scaffolding is required inside the room, so there is no need for a huge space for scaffolding or huge costs for building scaffolding.

[0022] Furthermore, in the case where the face plate portion of the ceiling material is a porous face plate, this portion (face plate portion) can be formed of, for example, punched metal, which takes into consideration sound absorption, light weight, and the like. Furthermore, the roof structure is constructed on the support base of the ceiling material, and the direction of installation of the ceiling material is determined appropriately according to the slope of the base, etc. However, since there are no restrictions on the roof structure, either vertical or horizontal roofing can be selected as appropriate. [Reference example]

[0023] The ceiling structure of the present invention is a structure including a holding member 2 having a horizontal support base 21, and rising portions 12, 12' on the left and right sides of a face plate 11, as shown in the reference example of FIG. 1(a) or (2). The outside of each and a ceiling material (1) including support surface portions (13, 13') extending to the support base portion (21) and placed on the support base portion (21), and folded-down portions (14, 14') at the tips of the support surface portions (13, 13') folded down, and on the support base portion (21) of the holding member (2), Holding member 2 The supporting surface portions 13, 13' of adjacent ceiling materials 1, 1 on the left and right are connected in an overlapping manner. The rising portions, support surface portions, and folded portions formed on the left and right sides of the panel portion 11 are distinguished as 12, 13, and 14 on the side that will become the upper surface when stacked (left side in the drawing), and as 12', 13', and 14' on the side that will become the lower surface (right side in the drawing).

[0024] The face plate portion 11 of this ceiling material 1 is a flat punched metal plate with many circular holes formed therein, and a heat insulating material 6 such as a glass wool board is placed on the upper surface thereof. Furthermore, the rising portions 12, 12' and supporting surface portions 13, 13' of this ceiling material 1 are formed by raising the side ends of the panel portion 11 and extending them further outward, and the edges are further folded down to form locking pieces 14, 14'. That is, in this reference example, the support surface portions 13, 13' and the folded-down portions 14, 14' form narrow grooves (U-shaped) that are open at the bottom on the left and right sides of the face plate portion 11, so that it can be fitted into the support base portion 21 of the holding member 2 from above. Also, the face plate portion 11 and the rising portions 12, 12' form wide grooves that are open at the top, so that the heat insulating material 6 can be fitted into the support base portion 21 by dropping it in from above.

[0025] The retaining member 2 used in the ceiling structure is a piece of material made by bending a strip of steel material into an approximately Z-shape, as shown on the right side of Figure 2(b), with the upper horizontal cross piece being the support base part 21 and the lower horizontal cross piece being the fixing part 22 to the base 3, and the two being connected by the vertical vertical piece, the leg part 23. As shown in FIG. 2(b), the support base portion 21 is formed with a fixing hole 211 in advance for driving the fixing tool 1b therein.

[0026] Next, the support member 4, which is erected on the base 3 in the same manner as the holding member 2, and the exterior material 5, which is supported by the support member 4 and forms the roof surface, will be described with reference to FIG. 2(a). The base 3 is a structural body of cross beams, and is made of H-shaped steel or the like.

[0027] As shown in FIG. 2(b), the support member 4 is made up of a tight frame 4A located below, a receiving metal fitting 4B located above, and a connecting metal fitting 4C that connects the two. Of these, the tight frame 4A has long leg-like portions 42, 42 on either side of a horizontal top 41, the lower ends of which have fixing portions 43, 43 for attachment to the base 3, the receiving bracket 4B has an engaging portion 44 with which the exterior material 5 can be engaged and attached, and the connecting bracket 4C is a bolt and nut that connects the receiving bracket 4B to the top 41 of the tight frame 4A.

[0028] The exterior material 5 attached to this support member 4 is a vertically-roofed exterior material in which both side ends of a flat face plate portion (valley portion) 51 rise at an incline (rising portion 52), the upper end of which is bent outward in a bulging shape and then folded back, and the side edge is crimped and connected to the side edge of an adjacent exterior material 5, as shown in Figures 1(a) and 2(c). In the figure, reference numeral 53 simply indicates the portion that engages with the support member 4 (receiving metal fitting 4B), i.e., the engaged portion, but this engaged portion 53 is specifically a combination of a lower L-shaped portion 53a and an upper L-shaped portion 53b formed in the portion that bulges outward as shown in Figure 2(c). Reference numeral 54 indicates a mounting portion that is attached to the upper surface of the receiving metal fitting 4B, and reference numerals 55 and 56 indicate portions (crimping portions) where the side edges are overlapped and crimped (wrapped). Furthermore, the face plate portion 51 forms a valley-shaped portion, but the rising portions 52, 52 of adjacent exterior materials 5, 5 form a mountain-shaped portion.

[0029] The ceiling structure of this reference example is extremely simple, both in terms of the ceiling material 1 and the holding member 2 used, and simply connects the support surface portions 13, 13' formed on adjacent ceiling materials 1, 1 on the left and right in an overlapping manner to the support base portion 21 of the holding member 2, so construction can be easily carried out from the roof side, and work can be carried out without the need for measures such as forming scaffolding on the indoor side, making it extremely practical.

[0030] The reference example of Fig. 1(a) does not limit the construction procedure, but as shown in Fig. 1(b), after the retaining member 2 and supporting member 4 of the above-mentioned configuration are fixed by welding or the like onto the base 3, which is the cross beam (body), the left and right ceiling materials 1, 1 may be arranged, and then the insulating material 6 may be arranged, or as shown in Fig. 2(a), the insulating material 6 may be arranged in advance on the face plate portion 11, and the ceiling material 1 may be arranged between the retaining members 2, 2. During this work, workers perform the work from the roof side, specifically standing on the base 3 or the insulating material 6 attached to the base 3, and no scaffolding is required inside the room, so there is no need for a huge space for scaffolding or the enormous cost of building it. The exterior material 5 having the above-described configuration is then laid between the support members 4, 4, and adjacent exterior materials 5, 5 on the left and right are connected to form the roof structure, but of course, all construction of this roof structure is carried out from the roof side (above).

[0031] In Figure 1(a), the exterior material 5 that makes up the roof structure is a vertically laid exterior material, and the left-right direction of the drawing is a direction perpendicular to the flow direction (slope gradient), so the ceiling structure of this reference example also has ceiling material 1 arranged in a direction perpendicular to the flow direction. [Example]

[0032] Figure 3(a) shows an example in which a roof structure different from that of the reference example is constructed on top of the ceiling structure of the reference example. The components that make up the ceiling structure, the ceiling material 1, the retaining material 2, the base material 3, and the insulating material 6, are given the same symbols as those in the reference example and will not be described. The portions where the support surface portions 13, 13' of the ceiling materials 1, 1 are connected together in an overlapping manner on the support base portion 21 of the holding member 2 serve as mounting base surfaces for different roof structures.

[0033] The different roof structure in this Example 1 is formed by a horizontal roofing exterior structure shown in FIG. 3(b) and a base layer shown in FIG. 3(c). The horizontally laid exterior structure is constructed by arranging exterior material 7A, which is a horizontally laid exterior material with backing material 7c on its back side, together with backup material 7B, and is constructed by engaging the belowwater side molding portion 72 and the abovewater side molding portion 73 formed on the belowwater side and abovewater side, respectively, of the face plate portion 71 of adjacent exterior materials 7A, 7A in the flow direction (left and right direction in the drawing). The base layer is composed of continuous support material 8A arranged along the flow direction, insulating material 8B arranged between the continuous support materials 8A, and fixing brackets 8C, and is attached with retaining clips 7d fixed to the top surface of the continuous support material 8A. The continuous support material 8A is a continuous material with an inverted U-shaped cross section, and is fixed to the mounting base surface (the portion on the support base portion 21 of the holding member 2 where the support surface portions 13, 13' of the ceiling material 1, 1 are connected together in an overlapping manner) with fixing brackets 8C arranged to straddle it. Note that this fixing bracket 8C is fixed using (or is reused from) fixing bracket 1b that connects the support surface portions 13, 13' of the ceiling material 1, 1.

[0034] In this Example 1, the roof structure is constructed on the support surface portions 13, 13' of the ceiling material 1", so there are no restrictions on the ceiling structure at all with respect to the roof structure. As described above, a horizontal roofing exterior structure can be constructed, and vertical roofing can also be selected as appropriate.

[0035] In Figure 3(a), the exterior material 7A that constitutes the roof structure is a horizontally laid exterior material, and the left-right direction of the drawing is the flow direction (slope gradient), so the ceiling structure in this example is one in which the ceiling materials 1 are arranged adjacent to each other in the flow direction. [Example]

[0036] In the ceiling structure of Example 2 shown in Figure 4(a), the retaining member 2C is a C-shaped steel (a channel steel with a lip), and the ceiling material 1C has engaging portions 171, 171' near the base ends of the left and right rising portions 17, 17' of the approximately horizontal panel portion 16. That is, the ceiling material 1C in this Example 2 has left and right rising portions 17, 17' of the panel portion 16 as described above, support surface portions 18, 18' extending from the upper ends of the rising portions 17, 17' toward the retaining member 2C and placed on its upper flange 2d, and folded portions 19, 19' in which the tips of the support surface portions 18, 18' are folded down. As described above, the retaining member 2C in this Example 2 is a C-shaped steel, and therefore its upper flange 2d is a support base portion which is a horizontal horizontal piece, the web 2e is a leg portion which is a vertical longitudinal piece, and the lower flange 2f is a fixed portion which is a horizontal horizontal piece, but it may be a continuous material or a short width material. Additionally, a decorative material 9 is attached to the holding member 2C to hide the lower flange 2f from the indoor side.

[0037] In this embodiment 2, the ceiling material 1C has support surface portions 18, 18' with dimensions approximately the same as those of the support base portion 2d, as shown in Figure 4(d), so that when the support surface portions 18, 18' fit along the support base portion 2d, the rising portions 17, 17' fit along the leg portion 2e, and the folded-down portions 19, 19' fit along the lip 2g or the leg portion 2e, so that it can be installed very easily from the roof side in a snug, fitted state without any shifting to the left or right.

[0038] 4(c), the decorative material 9 in Example 2 is a joint cap including a decorative lower surface 91 that covers the lower flange 2f, opening, and upper flange 2d of the retaining member 2C, a decorative vertical surface 92, and an insertion portion 93. If the retaining member 2C is a continuous material, the decorative material 9 is also a continuous material, and if the retaining member 2C is a short width material, the decorative material 9 is also a short width material. Note that the tip of the decorative lower surface 91 is provided with an upward engaging piece 911 that engages with the base end of the lower flange 2f of the retaining member 2C, and the decorative vertical surface 92 is provided with an outwardly bulging pressing portion 921. Therefore, when installing the decorative material 9, if the bottom end of the decorative vertical surface 92 and the pressing portion 921 are held down with fingers and pressed from the side, the engaging piece 911 engages with the base end of the lower flange 2f and the insertion portion 93 is inserted along the upper flange 2d. That is, since the pressing portion 921 is formed to bulge outward, the decorative material 9 can be placed in the appropriate position without causing deformation of the decorative material 9.

[0039] The ceiling structure of this Example 2 is also extremely simple, both in the ceiling material 1C and the retaining member 2C used, and the support surface portions 18, 18' formed on adjacent ceiling materials 1C, 1C on the left and right can be connected to the support base portion 2d of the retaining member 2C in an overlapping manner, so construction can be easily carried out from the roof side, and work can be carried out without the need for measures such as forming scaffolding on the indoor side, making it extremely practical. In particular, in this second embodiment, C-shaped steel is used as the holding member 2C, so the support strength is extremely high, and the stability of the roof structure formed on this ceiling structure is also high.

[0040] FIG. 4(b) shows an example in which the horizontal roofing exterior structure shown in FIG. 3 is constructed on top of the ceiling structure of the second embodiment, and the same reference numerals as those in FIG. 4 are used in the drawing and the description thereof will be omitted. The portion where the support surface portions 18, 18' of the ceiling materials 1C, 1C are connected together in an overlapping manner on the upper flange (support base portion) 2d of the holding member 2C serves as a mounting base surface for the horizontally laid exterior structure.

[0041] In this Example 2, the roof structure is constructed on the support surface portions 18, 18' of the ceiling material 1C, so there are no restrictions on the ceiling structure with respect to the roof structure, and as mentioned above, a horizontal roofing exterior structure can be constructed, and vertical roofing can also be selected as appropriate. Furthermore, the engaging portions 171, 171' of this ceiling material 1C are not portions that engage with the holding member 2C as described above, nor are they portions to which decorative material or hanging hardware, etc. are attached, but are pressing portions that press the rising portions 17, 17' from the side against the holding member 2C. In other words, like the pressing portion 921 of the decorative material 9, these engaging portions 171, 171' function to prevent deformation when strongly pressed from the side.
