Description

Technical Field

[0001] The present invention relates to a partition outer frame structure and an installation method thereof.

Background Art

[0002] In order to provide a sliding door that serves as an entrance and exit for the inside and outside or the partitioned space inside a building, a partition outer frame is provided in an opening provided in an indoor wall portion or the like. As one of the installation methods of the partition outer frame, there is a method of fixing the vertical frames to the left and right wall portions of the opening and then fixing the horizontal frame. Alternatively, there is a method of separately fixing a vertical frame adjacent to the vertical frame on which the partition is installed and then fixing the horizontal frame. In any case, the opening requires a width dimension of approximately two panels, specifically around 2 m, in the state where the entrance and exit is closed with a sliding door and in the state where the sliding door is stored in a door pocket and the entrance and exit is open. Since the horizontal frame of the partition is provided across substantially both ends of the opening for installing the sliding door, it has a length of around 2 m. Moreover, since the horizontal frame may be used to hang a sliding door or install a shoji window or the like above, it is provided robustly and has a relatively large load. As methods for fixing the horizontal frame to the vertical frame, various methods have been developed (for example, Patent Documents 1 and 2 below). Any of the inventions described in Patent Documents 1 and 2 is a method of covering the upper end of the vertical frame with the horizontal frame and fixing it with a fixing member.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since any of the inventions described in Patent Documents 1 and 2 has a structure in which a horizontal frame is installed at the uppermost end of the vertical frame, it cannot be adopted when it is desired to fix a horizontal frame below (the middle part in the vertical direction) the upper end of the vertical frame. Further, since it is configured to tighten the screws from the back side of the vertical frame, it cannot be adopted when fixing the horizontal frame after fixing the vertical frame to the building body or an adjacent vertical frame. Furthermore, since all of the conventional methods for fixing a horizontal frame to a vertical frame are complicated, there has been a problem that in installing a horizontal frame for installing a sliding door, work by a plurality of people is inevitable to ensure stability. Therefore, the present invention provides a partition outer frame structure and an installation method thereof that enable easy installation and temporary installation of a horizontal frame on a vertical frame, and enable work by a single person for final fixing.

Means for Solving the Problems

[0005] The partition outer frame structure of the present invention includes a pair of left and right vertical frames that are erected and fixed in openings formed in wall portions that partition a space, and a horizontal frame provided horizontally between the pair of vertical frames. The horizontal frame is formed surrounded by at least four sides of a top wall portion, a bottom wall portion, and side wall portions. Locking portions having fixing pieces extending from the bottom wall portion and locking pieces extending vertically from the tips of the fixing pieces are provided at both longitudinal ends of the horizontal frame. A notch that opens downward is formed in the locking piece, and an insertion hole is formed in the vertical frame at a position corresponding to the notch at the installation position of the horizontal frame. The insertion hole is provided with a screw that can be tightened, and the horizontal frame is placed above the screw so that the notch is locked to the screw, and the screw is tightened so that the horizontal frame can be tightened to the vertical frame. According to this configuration, the horizontal frame can be temporarily installed on the vertical frame by positioning the horizontal frame above the screw of the vertical frame, lowering the horizontal frame, and hanging the notch of the locking piece on the screw. Therefore, an operator can perform the temporary fixing work of lifting the horizontal frame and lowering it while checking both ends from below alone.

[0006] The horizontal frame of the partition outer frame structure of the present invention may be covered with a cover member including at least a part of the locking portion. According to this configuration, when a member such as a hanger rail is fixed to the lower surface of the bottom wall portion of the middle horizontal frame, the fixed state can be reinforced.

[0007] The inner side surface of the opening of the vertical frame of the partition outer frame structure of the present invention is formed in a U-shaped cross-section with a recess continuously extending in the vertical direction at the intermediate portion in the lateral direction of the inner side surface, and the locking piece may be formed with a width dimension corresponding to the recess of the recess so as to fit into the recess, and may be provided at positions protruding from both ends of the bottom wall portion. According to this configuration, since the horizontal frame can be lowered with the locking piece accommodated in the recess, the horizontal frame can be more easily attached to the screws of the vertical frame by using the recess as a so-called guide groove.

[0008] An insertion hole for inserting a screw that can be tightened may be formed in the locking piece of the partition outer frame structure of the present invention, and a screw hole for screwing the screw may be formed in the vertical frame. According to this configuration, the screw can be inserted into the insertion hole and the screw hole and tightened to reinforce the fixing of the locking piece to the vertical groove.

[0009] The fixing piece of the partition outer frame structure of the present invention may be fixed to the lower surface of the bottom wall portion. According to this configuration, it becomes easy to fix the fixing piece to the bottom wall portion.

[0010] An insertion hole for inserting a screw is formed in the fixing piece of the partition outer frame structure of the present invention, and a long hole is formed at an end portion of the bottom wall portion at a position corresponding to the insertion hole of the fixing piece when the fixing piece is applied. The fixing piece may be fixed to the bottom wall portion in a state where the screw is inserted through the insertion hole and the long hole and tightened. According to this configuration, the fixing piece can be temporarily fixed to the bottom wall portion, and the horizontal frame can be temporarily installed on the screws of the vertical frame. Therefore, after finely adjusting the position of the horizontal frame in the horizontal direction, the fixing piece can be fixedly attached to the bottom wall portion.

[0011] The installation method of the partition outer frame of the present invention uses any one of the partition outer frame structures described above. Insert the screw through the insertion hole such that the head of the screw and a part of the shank of the screw protrude from the vertical frame. Hook the notch of the locking piece onto the shank of the screw, place the horizontal frame between the pair of vertical frames, and tighten the screw to fix the horizontal frame to the vertical frame. According to this configuration, it becomes easy to temporarily install the horizontal frame to the vertical frame.

[0012] The installation method of the partition outer frame of the present invention uses a partition outer frame structure in which an insertion hole for inserting a screw that can be tightened is formed in the locking piece, and a screw hole for screwing in the screw is formed in the vertical frame. Insert the screw through the insertion hole such that the head of the screw and a part of the shank of the screw protrude from the vertical frame. Hook the notch of the locking piece onto the shank of the screw, place the horizontal frame between the pair of vertical frames, tighten the screw, and further insert and tighten the screw into the insertion hole formed in the locking piece and the screw hole formed in the vertical frame to fix the horizontal frame to the vertical frame. According to this configuration, the horizontal frame can be more firmly fixed to the vertical frame.

[0013] The installation method of the partition outer frame of the present invention uses a partition outer frame structure in which an insertion hole for inserting a screw is formed in the fixing piece, and a long hole is formed at the end of the bottom wall portion at a position corresponding to the insertion hole of the fixing piece when the fixing piece is applied. Insert the screw through the insertion hole formed in the fixing piece and the long hole formed in the bottom wall portion to temporarily fix the locking portion to the bottom wall portion. Insert the screw through the insertion hole such that the head of the screw and a part of the shank of the screw protrude from the vertical frame. Hook the notch of the locking piece onto the shank of the screw protruding from the vertical frame, place the horizontal frame between the pair of vertical frames, and after tightening the screw inserted through the vertical frame, completely tighten the screw inserted through the fixing piece and the bottom wall portion for temporary fixing to fix the horizontal frame to the vertical frame. According to this configuration, after finely adjusting the horizontal position of the horizontal frame to the vertical frame, the fixing piece can be fixed to the bottom wall portion.

Advantages of the Invention

[0014] The partition outer frame structure of the present invention has the effect that after temporarily installing the horizontal frame on the vertical frame easily, final fixing can be performed, enabling a single operator to install the outer frame structure.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, with reference to the drawings, one embodiment of the partition outer frame structure of the present invention and the installation method of the partition outer frame will be described.

[0017] As shown in Fig. 1, the outer frame structure 1 of the partition of the present invention includes, for example, vertical frames 2, 2 fixed to both left and right ends of an opening W1 formed in a side wall W of a building, and a middle horizontal frame (horizontal frame) 3 arranged at a position spaced apart from the uppermost end of the vertical frames 2, 2.

[0018] Specifically, in the opening W1 of the side wall W of the building, a pair of left and right vertical frames 2, 2, an upper horizontal frame 4, and a middle horizontal frame 3 are provided, and shoji windows 5, 5, etc. are installed between the upper horizontal frame 4 and the middle horizontal frame 3. Slide doors 6, 6 are installed between the vertical frames 2, 2, the middle horizontal frame 3, and the floor surface F (or, in some cases, a plain lower horizontal frame). The specific application object of the present invention is an outer frame for installing partitions such as school classrooms and entrances to each room in a building.

[0019] Hereinafter, the structures of each component will be described in detail. The vertical frame 2 has a length from the upper end to the lower end of the opening W1 of the building body, and is a rail member fixed to the left and right inner end faces of the opening W1 with screws or the like.

[0020] As shown in Fig. 2 or Fig. 3, the vertical frame 2 projects into the opening W1, fixes the upper horizontal frame 4 and the middle horizontal frame 3 shown in Fig. 1, and includes a main body portion 2a for receiving the slide door 6, and an anchor portion 2b that is fitted into the wall portion (or building body) forming the opening W1 and fixed with screws or the like. The main body portion 2a and the anchor portion 2b are integrally formed.

[0021] As shown in Fig. 3, the main body portion 2a forms a recess 7 penetrating in the longitudinal direction (the depth direction of the paper surface of Fig. 3) in the middle portion leaving both end portions in the short hand direction (arrow y direction) of the surface facing the opening W1. Thereby, the main body portion 2a is formed in a substantially U shape when viewed in the longitudinal direction. The recess 7 is surrounded by three surfaces and formed in a substantially rectangular shape. The surface facing the opening W1 is the groove bottom surface 7b.

[0022] In the recess 7, a reinforcing plate 8 is provided on the back surface of the groove bottom surface 7b corresponding to two notches 9 (see Fig. 4(a)) of the middle horizontal frame 3 described later, and two screw holes 10 are formed. Another screw hole 11 is further formed between the two screw holes 10. In the screw hole 10 formed at a position corresponding to the notch 9, a screw 12 with a part of its head 12a and body 12b protruding toward the opening W1 side is screwed in. As the screw 12, a bolt, a screw, or the like can be preferably used.

[0023] The protruding dimension of the head 12a of the screw 12 is equal to or greater than the thickness dimension of the locking piece 23 described later. The anchor part 2b extends substantially parallel to each other from both ends of the plate member forming the main body part 2a, and is a part that covers the wall part (body) and is fixed to the wall part with screws or the like.

[0024] As shown in FIG. 1, the upper horizontal frame 4 is attached so as to face the upper surface of the opening W1 by fixing both ends to the upper ends of the vertical frames 2 or the like. The middle horizontal frame 3 is a long bar member that is fixed to the left and right vertical frames 2 with a space between it and the upper horizontal frame 4. On the lower surface of the upper horizontal frame 4 and the upper surface of the middle horizontal frame 3, the illustrated upper and lower shoji rails are respectively fixed, and the shoji windows 5, 5 are fitted between the upper and lower shoji rails.

[0025] As shown in FIG. 4(a), when viewed in the longitudinal direction (i.e., the depth direction of the paper surface in FIG. 4(a)), the middle horizontal frame 3 is formed in a substantially rectangular C-shape. The middle horizontal frame 3 may be formed in a closed rectangle. In this embodiment, the middle horizontal frame 3 has top wall portions 15, 15 with their plate surfaces facing the vertical direction, arranged in parallel with a central portion in the short side direction left open, side wall portions 16, 16 that bend downward from both ends of the top wall portions 15, 15, and a bottom wall portion 17 that closes the space between the side wall portions 16, 16. The material constituting the middle horizontal frame 3 is a steel plate or the like having a predetermined thickness.

[0026] As shown in FIG. 2, a hanger rail 20 for hanging a sliding door is fixed to the lower surface 18 of the bottom wall portion 17 of the middle horizontal frame 3 using screws 13. The hanger rail 20 is arranged along the longitudinal direction leaving both end portions 17b of the bottom wall portion 17. As shown in FIG. 5, the hanger rail 20 is fixed in parallel in two in the width direction of the middle horizontal frame 3, and is provided so that the sliding doors 6 shown in FIG. 1 can be arranged on the inner side S1 side and the outer side S2 side of the partitioned space (such as a room), respectively.

[0027] As shown in FIG. 6, a locking portion 21 is fixed to the lower surface 18 of the bottom wall portion 17 on the extension line of the hanger rail 20. As shown in FIGS. 4 and 6, the locking portion 21 has a fixing piece 22 fixed to both longitudinal ends of the bottom wall portion 17 and a locking piece 23 hanging down from the fixing piece 22.

[0028] The fixing piece 22 is fixed to the lower surface 18 of the bottom wall portion 17. A part of the fixing piece 22 is provided so as to protrude from both ends 16a of the side wall portion 16 and the end surfaces 27a of the side plate portions 27 of the cover member 25. The protruding dimension is set to be approximately the same as the depth d of the recess 7 of the vertical frame 2. When the surface facing the opening W1 of the vertical frame 2 is formed as one flat surface, the fixing piece 22 may be formed so as not to protrude with its tip aligned with both ends 16a (in the longitudinal direction) of the side wall portion 16 of the middle horizontal frame 3.

[0029] The fixing piece 22 and the locking piece 23 are formed in a substantially L-shape in a cross-sectional view cut in the thickness direction by bending a steel plate or the like. As shown in FIG. 4(a), the locking piece 23 is formed in a substantially rectangular shape having a notch 9 downward. The width dimension of the locking piece 23 is formed slightly smaller than the groove bottom surface 7b, and the locking piece 23 is formed so that its plate surface faces the groove bottom surface 7b and can be accommodated in the recess 7.

[0030] Further, the locking piece 23 hangs downward from the lower surface 18 of the bottom wall portion 17 and protrudes further downward than the lower plate portion 28 of the cover member 25 described later. Two notches 9 of the locking piece 23 are formed at intervals along the lower end edge 23c of the locking piece 23.

[0031] The notch 9 extends downward from the middle portion in the vertical direction of the locking piece 23, and opens so as to spread more toward the lower end edge 23c in the vicinity of the lower end edge 23c. An insertion hole 24 for the screw 12 is formed between the notches 9.

[0032] The middle horizontal frame 3 having the above configuration can be temporarily installed with respect to the vertical frame 2 by hooking the notches 9, 9 of the locking portions 21 fixed to both end portions of the bottom wall portion 17 from above onto the screws 12, 12 protruding from the recesses 7 of the left and right vertical frames 2.

[0033] As shown in FIG. 5, the middle horizontal frame 3 and the hanger rail 20 are entirely covered with a cover member 25. The cover member 25 has an upper plate portion 26 that covers the top wall portions 15, 15 of the middle horizontal frame 3, side plate portions 27, 27 that hang down from both end edges in the short side direction of the upper plate portion 26 and cover the side wall portions 16, 16 of the middle horizontal frame 3, and plate portions 28, 28 that extend under the hanger rail 20.

[0034] A sliding door 6 shown in FIG. 2 is suspended from the hanger rail 20 via a hanger roller (not shown) so as to be movable in the longitudinal direction of the rail.

[0035] Next, a method for installing the partition outer frame structure 1 of the present invention and a method for installing a partition using the same will be described. To install the partition outer frame structure 1, as shown in FIG. 3 or FIG. 4(b), first, the screws 12 are inserted into the screw holes 10, 10 formed in the recesses 7 of the vertical frames 2 until the heads 12a of the screws 12 and a part of the heads 12a protrude from the groove bottom surface 7b of the recesses 7. As shown in FIG. 6, the hanger rail 20 and the locking portion 21 are fixed to the middle horizontal frame 3 in advance. Then, the cover member 25 is put on the middle horizontal frame 3 and the hanger rail 20.

[0036] Specifically, leaving both end portions 17b of the lower surface 18 of the bottom wall portion 17, the hanger rail 20 is fixed to the lower surface 18 of the bottom wall portion 17 by screws 12. Locking portions 21 are fixed to both end portions 17b of the lower surface 18 of the bottom wall portion 17 by welding or the like so that locking pieces 23 project from both ends. Then, the middle horizontal frame 3 with the hanger rail 20 fixed inside the cover member 25 is inserted. Further, hanger rollers (not shown) are accommodated in the hanger rail 20. Depending on the structures of the hanger rail 20 and the hanger rollers, the hanger rollers may be attached after the middle horizontal frame 3 is fixed to the vertical frames 2, 2.

[0037] As shown in FIG. 5, the hanger rail 20, the locking portion 21, and the middle horizontal frame 3 to which the hanger rails 20, 20 are attached are lifted above the screws 12 of the vertical frame 2 as shown in FIG. 6, and the locking pieces 23 projecting from the bottom wall portion 17 with the opening of the notch 9 facing downward are positioned between the recesses 7. In this way, the middle horizontal frame 3 is arranged between the left and right vertical frames 2. With the middle horizontal frame 3 in the above state, it is lowered so that the locking piece 23 moves downward within the recess 7. At this time, since the recess 7 can serve as a guide groove for the locking piece 23, the temporary installation of the middle horizontal frame 3 can be facilitated.

[0038] When the middle horizontal frame 3 is lowered as described above, the middle horizontal frame 3 further descends while passing the body portion 12b of the screw 12 through the notch 9 of the locking piece 23. The locking piece 23 is in a state of being hung on the screw 12 at the upper end of the notch 9 as shown in FIG. 5, and the middle horizontal frame 3 is in a temporarily installed state on the vertical frame 2.

[0039] Once the notch 9 is hooked on the screw 12, the screws 12 protruding inside the locking piece 23 are tightened respectively. Then, as shown in FIG. 2, since the head portion 12a of the screw 12 strongly presses the locking piece 23 against the groove bottom surface 7b of the vertical frame 2, the middle horizontal frame 3 is fixed to the vertical frame 2 via the locking portion 21. Thereby, the fixing of the middle horizontal frame 3 to the vertical frame 2 is completed.

[0040] Also, when the notch 9 of the locking piece 23 catches on the screw 12, the insertion hole 24 formed in the locking piece 23 shown in Fig. 4(a) and the screw hole 11 formed in the vertical frame 2 coincide. Therefore, a bolt 12 is screwed into these insertion hole 24 and screw hole 11, and the fixing of the locking piece 23 to the vertical frame 2 is strengthened. After that, a slide door 6 shown in Fig. 1 is attached to a hanger roller (not shown) so as to be movable along a hanger rail 20, and the installation of the partition is completed.

[0041] Thus, according to the outer frame structure 1 of the partition of the present invention, it is possible to easily hook the vertical frame 2 on the screw 12 while looking from below the middle horizontal frame 3 with the locking piece 23 lifted upward from the lower surface 18 of the bottom wall portion 17.

[0042] That is, since the middle horizontal frame 3 is arranged above the screw 12 of the vertical frame 2, the locking piece 23 is stored in the recess 7, and the middle horizontal frame 3 is simply lowered along the recess 7, even if the middle horizontal frame 3 has a length of about 2 m and a load including the hanger rail 20 and the like, an operator can easily perform the above work alone.

[0043] Further, the locking piece 23 extends downward from the lower surface 18 of the middle horizontal frame 3 in a substantially vertical direction, and the tip thereof extends below the lower plate portion 28 of the cover member 25. That is, the tip of the locking piece 23 is more likely to hit the vertical frame 2 before the middle horizontal frame 3 and the cover member 25. As a result, it is possible to easily arrange both ends of the middle horizontal frame 3 between the vertical frames 2 while searching for the recess 7 with the tip of the locking piece 23.

[0044] In addition, since the screw 12 can be tightened from the opening W1 side in a state where the locking piece 23 is hooked on the screw 12, an operator can easily perform the tightening work alone.

[0045] In addition to the screw 12 protruding from the notch 9, since the screw 12 can be inserted into the insertion hole 24 and the screw hole 11 and tightened, the fixing of the middle horizontal frame 3 to the vertical frame 2 becomes more reliable.

[0046] In addition, in the above-described embodiment, although the locking portion 21 and the vertical frame 2 through which the screw 12 can be further inserted into the insertion hole 24 and the screw hole 11 have been described, these are not essential. Also, the cover member 25 is preferably provided but not essential.

[0047] In addition, in the above-described embodiment, the fixing piece 22 is fixed to the lower surface 18 of the bottom wall portion 17, but it is also possible to fix it to the upper surface of the bottom wall portion 17.

[0048] In the above-described embodiment, the case where welding fixation is performed in fixing the locking portion 21 to the lower surface 18 of the bottom wall portion 17 has been illustrated, but the locking portion 21 may be fixed by the following method. That is, as shown in FIG. 7, an insertion hole 30 having a female screw hole through which the screw 14 is inserted into the fixing piece 22 of the locking portion 21 is formed, and a long hole �1 extending in the longitudinal direction of the bottom wall portion 17 is formed in the bottom wall portion 17 of the middle horizontal frame 3 corresponding thereto.

[0049] Then, the screw 14 is screwed into the insertion hole 30 and the long hole 31 to temporarily fix the locking portion 21 to the bottom wall portion 17. Then, the middle horizontal frame 3 is lifted above the screw 12 of the vertical frame 2, and in the same manner as the above-described method, the middle horizontal frame 3 is lowered along the recess 7, and with the notch 9 caught on the screw 12, the horizontal position of the middle horizontal frame 3 is determined after adjustment.

[0050] At the position where the horizontal position of the middle horizontal frame 3 is determined, the screw 14 inserted through the fixing piece 22 is tightened to fix the locking piece 23 to the bottom wall portion 17. The subsequent procedure is the same as the above-described fixing method of the middle horizontal frame 3. By fixing the locking piece 23 of the locking portion 21 to the bottom wall portion 17 as described above, it is possible to finely adjust and then position the horizontal position between the vertical frames 2 of the middle horizontal frame 3.

[0051] Note that the vertical frame 2 may be welded to the ceiling portion (body) C forming the upper surface of the opening W1 via the anchor member 40 as shown in FIG. 8. The anchor member 40 specifically includes an L-shaped steel plate member 41 and a connecting member 42.

[0052] The connecting member 42 has a dimension larger than the dimension between the steel plate member 41 and the ceiling portion C. The connecting member is not particularly limited, but is formed of a welding material such as iron in a cylindrical or prismatic shape. In fixing the vertical frame 2 to the ceiling portion C, first, the steel plate member 41 is fixed to the vertical frame 2 such that one piece portion 41a of the steel plate member 41 faces horizontally at the upper end portion of the vertical frame 2 and the other piece portion 41b rises upward.

[0053] The connecting member 42 is arranged with one end 42a in contact with the steel plate member 41 and the other end 42b in contact with the ceiling portion C, and the respective contact portions P, P are fixed by welding. The welding portion may be, for example, about 10 mm in diameter.

[0054] In this way, by fixing the vertical frame 2 to the ceiling portion C via the anchor member 40, there is an effect that the vertical frame 2 can be fixed to the building body more stably. In particular, when the vertical frame 2 is fixed to the vertical frames 2 of the adjacent partitions, there is an effect that the stability can be further improved.

[0055] Note that the anchor member 40 may be composed of a material to which a strong adhesive can be used in addition to weldable materials, as long as it can be surely fixed to the vertical frame 2 and the building body.
