Description

[Technical Field]

[0001] The present invention relates to an access opening forming device for a structure. [Background technology]

[0002] An example of a structure for fixing frame materials when forming an opening in a building skeleton is the structure disclosed in Patent Document 1. In the following description of the background art, the figure numbers, symbols, and paragraph numbers are those described in Patent Document 1.

[0003] This structure is a fixing structure for frame material 11 when a steel plate frame body is attached to an opening in a building framework via base material 21, and includes a pair of mounting members 22a, 22a fixed to the side surface of base material 21 facing the frame material 11, a fixing rib 11a of the frame material formed to protrude toward base material 21, and connection plates 23 corresponding to each of a plurality of fixing plates 12 that cross the opening portion of frame material 11 on the base material 21 side at a predetermined pitch. The fixing rib 11a is screwed to one side of the mounting material, and each connecting plate 23 is configured to engage with the corresponding fixing plate 12 and also screwed to the other side of the mounting material.

[0004] The frame material 11 forms the inner side surface of the opening, and the fixing rib forming one end of the frame material 11 has a fixing rib bent toward the base material 21, or has a fixing rib formed by combining separate angle pieces. The fixing rib is configured to be directly screwed to one side of the mounting material.

[0005] In contrast, the other end portion of the frame material 11 is not directly screwed to the other side of the mounting material, but is configured to use the fixing plates 12 and the connecting plates 23 corresponding to the fixing plates 12, and the connecting plates 23 engaged with the corresponding fixing plates 12 are screwed to the other side of the mounting material.

[0006] Therefore, the structure according to Patent Document 1 has the following problems. (1) The other end of the frame material 11 is not directly screwed to the other side of the mounting material, but the connecting plate 23, which is engaged with the fixing plate 12, is screwed to the mounting material. Therefore, when using the structure of Patent Document 1, the fixing plates 12 must be attached to the frame material 11 so that they cross at a predetermined pitch (paragraph 0018), and the connecting plate 23 must be locked to the corresponding fixing plate 12. As shown in Figure 5, this locking requires alignment and insertion / locking operations, in which a required portion of the side edge of the corresponding fixing plate 12 is inserted into the deepest part of the locking groove 23b (Figure 4) provided in the connecting plate 23 to lock it (paragraph 0022). After that, the connecting plate 23 must be screwed to the other side of the mounting plate. For this reason, when the structure of Patent Document 1 is used, for example, to form an entrance and exit opening in a partition, as described above, the fixing plates 12 must be welded in multiple stages (for example, 5 to 6 stages) at required intervals in the extension direction of the frame material 11, at a required pitch of, for example, 450 mm or less, and since the connecting plate 23 requires precise positioning and locking work, it takes a lot of time to screw the other end of the frame material 11 to the other side of the mounting material, resulting in a problem of poor workability on site.In addition, there is also the problem that the connecting plate 23 cannot be precisely positioned, which easily causes the vertical and horizontal accuracy of the frame material 11 to be distorted.

[0007] (2) Furthermore, if the work of engaging the connecting plate 23 to the fixed plate 12 is carried out by inserting a required portion of the side end of the fixed plate 12 into the engaging groove 23b of the connecting plate 23, as described above, there is a risk that the engagement may loosen due to earthquake vibrations, for example, and the strength of the entrance and exit opening may become unstable.

[0008] (3) Furthermore, the structure described in Patent Document 1 requires at least the fixing plate 12 and the connecting plate 23 in addition to the frame material 11, resulting in a large number of components. This necessitates the production of a mold for each component, and the manufacturing process is labor-intensive, resulting in increased manufacturing costs. Furthermore, the large number of components at the construction site creates the problem of labor-intensive handling.

[0009] (4) In addition, when constructing the entrance opening, as shown in Figure 1 of Patent Document 1, wall materials are attached to both the front and rear sides of the base material 21, but as mentioned above, the connection plates 23, which also serve to support the edge portions of the wall materials from the back side, are not attached over the entire length of the frame material 11, but are attached at a predetermined pitch in the length direction. Therefore, the edge portions of the wall materials are not supported between adjacent connection plates 23, 23, which causes a problem of unstable support of the edge portions.

[0010] [Patent Document 1] Patent Publication No. 2014-218839 Summary of the Invention [Problem to be solved by the invention]

[0011] The present invention was developed in consideration of the above-mentioned conventional problems, and aims to provide an entrance / exit opening configuration device for a structure that can improve productivity by reducing the number of parts, improve workability by simplifying construction, and also improve the strength of the door opening. [Means for solving the problem]

[0012] In order to solve the above problems, the present invention employs the following means. That is, the device for forming an entrance / exit opening in a partition according to the present invention is a device for forming an entrance / exit opening in a structure, and includes a base member fixed with screws to a base member for the entrance / exit opening, and a frame member fixed with screws to the base member. The base member is configured by bending a single metal plate and extending it linearly with the same cross-sectional shape, and a base piece fixed with screws to the base member has a first short-length connecting piece with a smaller protruding length that protrudes toward the entrance / exit opening on one side edge of the base piece, as viewed in the entrance / exit direction of the entrance / exit opening, and a first long-length connecting piece with a larger protruding length that protrudes from the other side edge. The frame member is configured by bending a single metal plate and extending it linearly with the same cross-sectional shape, and a frame member body forming the inner side surface of the entrance / exit opening has side pieces of equal length that protrude toward the base member on each of the two side edges, as viewed in the entrance / exit direction of the entrance / exit opening, bent and formed. At the tip edge of each side piece, an inner piece of equal length is bent and formed, protruding in the opposite direction and capable of abutting the tip surface of the wall board, and at one of the tip edges of both inner pieces, a large-length second connecting piece of greater protrusion length is bent and formed, overlapping at its tip end portion with the outer surface of the small-length first connecting piece, and at the other edge, a small-length second connecting piece of less protrusion length is bent and formed, overlapping at its tip end portion with the inner surface of the large-length first connecting piece, and the overlapping portions of the small-length first connecting piece and the large-length second connecting piece and the large-length first connecting piece are fixed with screws, respectively. [Effects of the Invention]

[0013] When using the entrance / exit opening forming device for a structure according to the present invention, the base member and the frame member are each integrally formed by bending a single metal plate, thereby improving productivity by reducing the number of components. Furthermore, because the frame member is integrally formed, there is no need for precise alignment or interlocking of the components, as in Patent Document 1. This reduces construction labor and improves workability. Additionally, because the entrance / exit opening is formed using a series of integral frame members formed by bending a single metal plate, an entrance / exit opening with high dimensional accuracy, such as vertical accuracy, and high strength can be formed.

DETAILED DESCRIPTION OF THE INVENTION [Example]

[0015] 1 to 5, the device 1 for forming an entrance opening for a structure according to the present invention comprises a base member 4 fixed with screws to a base material 3 of an entrance opening 2 of the structure, and a frame member 5 fixed with screws to the base member 4. In this embodiment, as shown in FIG. 1, the entrance opening 2 can be opened and closed by a hinged door 6.

[0016] 2 is a cross-sectional view taken along line AA in FIG. 1, FIG. 3 is a cross-sectional view taken along line BB in FIG. 1, FIG. 4 is a cross-sectional view taken along line CC in FIG. 1, and FIG. 5 is a perspective view of each member. The base member 4 is constructed by bending a single metal plate and extending it in a straight line with the same cross-sectional shape, and a base piece 7 is fixed to the base material 3 with screws. On one side edge 9a of the two side edges 9, 9 viewed in the entrance / exit direction of the entrance / exit opening 2, a short-length first connecting piece 10 with a small protruding length is provided, which protrudes toward the entrance / exit opening 2, and on the other side edge 9b, a long-length first connecting piece 11 with a large protruding length is provided. The frame member 5 is constructed by bending a single metal plate and extending it in a straight line with the same cross-sectional shape, and the frame member main body 13 which forms the inner surface portion 12 of the entrance / exit opening 2 has side pieces 16, 16 of equal length bent and formed on each of the both side edges 15, 15 when viewed in the entrance / exit direction of the entrance / exit opening 2, and inner pieces 20, 20 of equal length bent and formed on the tip edges 17, 17 of each of the side pieces 16, 16 which protrude in the opposite direction and can abut against the tip surface 19 of the wall board 18. A large-length second connecting piece 24 having a large protruding length is bent and formed on one 21a of the tip edges 21, 21 of the inner pieces 20, 20, and overlaps an outer surface 22 of the small-length first connecting piece 10 at a tip-side portion 23 thereof. A small-length second connecting piece 27 having a small protruding length is bent and formed on the other 21b of the tip edges 21, 21a of the inner pieces 20, 20, and overlaps an inner surface 25 of the large-length first connecting piece 11 at a tip-side portion 26 thereof. The overlapping portions of the small-length first connecting piece 10 and the large-length second connecting piece 24 and the overlapping portions of the large-length first connecting piece 11 and the small-length second connecting piece 27 are fixed with screws, respectively.

[0017] This will be explained in detail below. 1 to 4, the base material 3 extends linearly in the vertical direction or horizontal direction of the entrance / exit opening 2. In this embodiment, as shown in the figures, the base material 3 is configured as a channel material with a lip with a bottom surface 29 facing the entrance / exit opening 2, and its thickness is set to, for example, 2.3 mm.

[0018] The base member 4 is formed by bending a single metal plate (e.g., a steel plate) and extending linearly with the same cross-sectional shape in the vertical or horizontal direction of the entrance / exit opening 2 shown in FIGS. 1 to 4 . The base piece 7, which is fixed with screws to the bottom surface portion 29 of the base member 3, has a first short-length connecting piece 10 with a short protruding length and a first long-length connecting piece 11 with a long protruding length, which protrude toward the entrance / exit opening 2, bent at both side edges 9, 9 of the base piece 7, as viewed in the entrance / exit direction F (FIGS. 2 to 4) of the entrance / exit opening 2. The thickness of each piece is set to, for example, 2.3 mm. In FIGS. 1 to 4 , the first short-length connecting piece 10 is located on the side where the hinged door 6 is attached, and the first long-length connecting piece 11 is located on the opposite side from the side where the hinged door 6 is attached.

[0019] The frame member 5 is formed by bending a single metal plate (e.g., a steel plate) and extending linearly with the same cross-sectional shape in the vertical direction of the entrance / exit opening 2 shown in Figures 1 to 3, and its thickness is set to, for example, 1.6 mm. The frame member 5 has side pieces 16, 16 of equal length that protrude toward the base member 4 bent and formed on both side edges of the frame member main body 13 that forms the inner side surface portion 12 of the entrance / exit opening 2, as seen in the entrance / exit direction of the entrance / exit opening 2, and inner pieces 20, 20 of equal length that protrude in opposing directions and can abut against the tip surface 19 of the wall board 18 are bent and formed on the tip edges 17, 17 of each of the side pieces 16, 16. The large-length second connecting piece 24 is bent and formed on the tip edge 21a of one of the inner pieces 20, 20, overlapping at a tip side portion 23 with the outer surface 22 of the small-length first connecting piece 10 and fixed with a screw to the small-length first connecting piece 10. The small-length second connecting piece 27 is bent and formed on the other tip edge 21b, overlapping at a tip side portion 26 with the inner surface 25 of the large-length first connecting piece 11 and fixed with a screw to the large-length first connecting piece 11. In this embodiment, a door stop 28 of the hinged door 6 is bent and formed on the frame member main body 13.

[0020] As shown in Figure 5, screw holes 36 are pre-formed in the base piece 7, the long first connecting piece 11, and the long second connecting piece 24 at the screw fixing locations, and the screw fixing is performed using a drill screw 37 inserted through the screw hole 36, as shown in Figures 2 to 4.

[0021] 6 and 7 show the process of attaching the frame member 5 to the base member 4 fixed with screws to the base material 3, and show the process of moving the frame member 5 laterally (in the direction shown by the arrow in FIG. 6) from the left side of FIG. 6 (the side where the hinged door 6 is attached) to the right side, so that the tip end portion 23 of the large-length second connecting piece 24 overlaps the outer surface 22 of the small-length first connecting piece 10, and the tip end portion 26 of the small-length second connecting piece 27 overlaps the inner surface 25 of the large-length first connecting piece 11, as shown in FIG. 7. When achieving this overlapping state, appropriate adjustment is made to move in and out.

[0022] Such lateral movement is possible because the protruding length of the small-length first connecting piece 10 is set to a small value, which prevents the small-length second connecting piece 27 moving in the lateral direction from colliding with the small-length first connecting piece 10.

[0023] After the lateral movement is completed, the tip end portion 23 of the overlapping large-length second connecting piece 24 is fixed to the small-length first connecting piece 10 with a screw (Figs. 2 to 4), and the tip end portion 26 of the small-length second connecting piece 27 is fixed to the large-length first connecting piece 11 with a screw (Figs. 2 to 4). This allows the frame member 5 to be attached to the base member 4 with screws.

[0024] Figure 8 shows a U-shaped frame body 39 formed by connecting upper ends 38, 38 of left and right frame members 5a, 5a extending in the vertical direction of the entrance / exit opening 2 with an upper frame member 5b extending in the horizontal direction of the entrance / exit opening 2. The method for fixing the U-shaped frame body 39 to a U-shaped base material 4 formed by fixing the base member 4 with screws to left and right vertical base materials 3, 3 (Figures 2 and 3) and a horizontal base material 3 (Figure 4) disposed above is the same as that explained based on Figures 6 and 7. That is, by moving the U-shaped frame body 39 laterally from left to right as shown in Fig. 6, the tip end portion 23 of the large-length second connecting piece 24 is overlapped with the outer surface 22 of the small-length first connecting piece 10, and the tip end portion 26 of the small-length second connecting piece 27 is overlapped with the inner surface 25 of the large-length first connecting piece 11, and after adjusting the entrance and exit as appropriate, the U-shaped frame body 39 is fixed with screws to the U-shaped base member 4 in the same way as shown in Figs. 2 to 4. This makes it possible to form an entrance and exit opening 2 with high dimensional accuracy and high strength and with good workability.

[0025] After the U-shaped frame 39 is attached with screws in this manner, the wall boards 18 are fixed to the base material 3 with appropriate screws on both sides of the U-shaped frame 39 as viewed in the entry / exit direction F, with their leading end surfaces 19 abutting against the inner pieces 20, as shown in Figures 2 to 4. Because the long-length second connecting pieces 24 and the short-length second connecting pieces 27 are continuously provided in the vertical and horizontal directions, the entire edge portion 41 of the wall board 18 is supported from the backside. Therefore, the wall board 18 is stably supported at its edge portion 41 as well, and a wall 42 (Figure 1) with a stable structure can be formed, including the edge portion 41. In this embodiment, a base board 43 is disposed so as to overlap the rear surface of the wall board 18, and a tip surface 45 of the base board 43 abuts against the base piece 7. [Example]

[0026] The present invention is by no means limited to the above-described embodiments, and it goes without saying that various design modifications are possible within the scope of the claims. Examples of such modifications are as follows.

[0027] (1) Figure 9 shows an entrance / exit opening forming device 1 for a structure in which the base material 3 is made of wood, and other configurations are the same as in Figure 2. The base member 4 has its base piece 7 fixed to the base material 3 with a screw 46.

[0028] (2) The entrance opening 2 may be made openable and closable by a sliding door or a folding door. In this case, the door stop 28 in Figs. 2 and 3 is not provided.

[0029] (3) The entrance opening 2 may be configured as a simple entrance without a hinged door, sliding door, or folding door.

[0030] (4) In the present invention, the entrance opening 2 may be configured as an entrance to a structure, or may be configured as an entrance to a structure such as a garage. [Explanation of symbols]
