Description

The present invention relates to an opening configuration device for entrance and exit to a structure.

The structure disclosed in Patent Document 1 is provided as an example of a structure for fixing frame materials when constructing an opening in a building structure. In the following description of the background art, the figure numbers, symbols, and paragraph numbers are those described in Patent Document 1.

This structure is a fixing structure for the frame material 11 when a steel plate frame body is attached to an opening in a building structure via a base material 21, and includes a pair of mounting members 22a, 22a fixed to the side surface of the base material 21 on the frame material 11 side, a fixing rib 11a of the frame material formed to protrude toward the base material 21, and connection plates 23 corresponding to each of the multiple fixing plates 12 that cross the opening part of the 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 of the connection plates 23 is configured to engage with the corresponding fixing plate 12 and to be screwed to the other side of the mounting material.

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.

In contrast, the other end of the frame material 11 is not screwed directly to the other side of the mounting material, but is configured to use the fixing plates 12 and the connection plates 23 that correspond to the fixing plates 12, and to screw the connection plates 23 that are engaged with the corresponding fixing plates 12 to the other side of the mounting material.

Therefore, the structure described in Patent Document 1 has the following problems.
(1) The other end portion of the frame material 11 is not directly screwed to the other side of the mounting material, but the connection plate 23 engaged with the fixing plate 12 is screwed to the mounting material.
Therefore, when using the structure of Patent Document 1, the fixing plate 12 must be attached to the frame material 11 so as to cross it at a predetermined pitch (paragraph 0018), and the connection plate 23 must be locked to the corresponding fixing plate 12. As shown in Figure 5, this locking requires a positioning operation and an entry/locking operation in which a required portion of the side end of the corresponding fixing plate 12 is inserted into the deepest part of the locking groove 23b (Figure 4) provided in the connection plate 23 to lock it (paragraph 0022). After that, the connection 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 configure an entrance and exit opening for a partition, as described above, the fixing plates 12 must be welded in a plurality of 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 precise alignment and locking work for the connection plate 23 is required, 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 poor workability on site. In addition, there is also the problem that the vertical and horizontal accuracy of the frame material 11 is easily disturbed if the connection plate 23 is not precisely aligned.

(2) Furthermore, if the work of engaging the connection plate 23 with the fixed plate 12 is performed by inserting a required portion of the side end of the fixed plate 12 into the engaging groove 23b of the connection plate 23, as described above, there is a risk that the engagement may become loose due to, for example, earthquake vibrations, which may destabilize the strength of the entrance and exit opening.

(3) Furthermore, when using the structure described in Patent Document 1, in addition to the frame material 11, at least the fixing plate 12 and the connection plate 23 are required, and the number of parts is large. This necessitates the production of a mold for each part, and there is a problem that a lot of manufacturing work is required, leading to an increase in manufacturing costs. In addition, there is a problem that the large number of parts requires a lot of work to handle at the construction site.

(4) In addition, when constructing the entrance opening, as shown in FIG. 1 of Patent Document 1, wall materials are attached to both the front and back of the base material 21. However, as described above, the connection plate 23, which also plays a role in supporting the edge portion of the wall material from the back side, is not attached over the entire length of the frame material 11, but is attached at a predetermined pitch in the length direction. Therefore, the edge portion of the wall material is not supported between adjacent connection plates 23, 23, which causes the support of the edge portion to become unstable.

Patent Publication 2014-218839

The present invention was developed in consideration of the above-mentioned conventional problems, and has as its object to provide an entrance/exit opening configuration device for a structure which can improve productivity by reducing the number of parts, improve workability by simplifying construction, and also improve the strength of the entrance/ exit opening .

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 a screw to a base member of the entrance/exit opening, and a frame member fixed with a screw to the base member. The base member is configured by bending a single metal plate and extending linearly with the same cross-sectional shape, and a base piece fixed with a screw to the base member has a first short-length connecting piece with a small protruding length protruding toward the entrance/exit opening at one side edge of both side edges of the base piece fixed with a screw in the entrance/exit opening direction, and a first long-length connecting piece with a large protruding length protruding from the other side edge. The frame member is configured by bending a single metal plate and extending linearly with the same cross-sectional shape, and a frame member main body forming an inner side surface of the entrance/exit opening has a side piece of equal length protruding toward the base member bent at each of both side edges of the frame member main body as viewed in the entrance/exit opening direction. At the tip edge of each side piece, an inner piece of equal length is bent so as to protrude in the opposite direction and be 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 with a larger protruding length is bent and formed so that its tip portion overlaps with the outer surface of the small-length first connecting piece, and at the other edge, a small-length second connecting piece with a smaller protruding length is bent and formed so that its tip portion overlaps 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 and the small-length second connecting piece are each fixed with a screw.

When using the entrance/exit opening configuration device for a structure according to the present invention, the base member and the frame member are each integrally configured by bending a single metal plate, which can improve productivity by reducing the number of components. In addition, since the frame member is integrally configured, there is no need to precisely align the members or to lock them together, as in Patent Document 1. This can reduce the amount of construction work required and improve workability. In addition, since the entrance/exit opening is configured using a series of integral frame members configured by bending a single metal plate, an entrance/exit opening with high dimensional accuracy, such as vertical accuracy, and high strength can be configured.

In Figures 1 to 5, the entrance/exit opening configuration device 1 for a structure according to the present invention comprises a base member 4 that is fixed with screws to a base material 3 of an entrance/exit opening 2 for the structure, and a frame member 5 that is fixed with screws to the base member 4. In this embodiment, as shown in Figure 1, the entrance/exit opening 2 can be opened and closed with a hinged door 6.

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, which is fixed to the base material 3 with screws, has a small-length first connecting piece 10 with a small protruding length on one side edge 9a of the two side edges 9, 9 when viewed in the entry/exit direction of the entrance/exit opening 2, and a large-length first connecting piece 11 with a large protruding length is provided on the other side edge 9b. 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 side pieces 16, 16 of equal length that protrude toward the base member 4 are bent and formed on each of the two side edges 15, 15 of the frame member main body 13 that forms the inner side surface portion 12 of the entrance/exit opening 2, when viewed in the entrance/exit direction of the entrance/exit opening 2, and inner pieces 20, 20 of equal length are bent and formed on the tip edges 17, 17 of each of the side pieces 16, 16, which protrude in the opposing direction and can abut against the tip surface 19 of the wall board 18. A large-length second connecting piece 24 having a larger protruding length is bent and formed on one 21a of the tip edges 21, 21 of the inner pieces 20, 20, the tip portion 23 of which overlaps with the outer surface 22 of the small-length first connecting piece 10, and a small-length second connecting piece 27 having a smaller protruding length is bent and formed on the other 21b of the tip edges 21, 21a of the inner pieces 20, 20, the tip portion 23 of which overlaps with the outer surface 22 of the large-length first connecting piece 10, and a small-length second connecting piece 27 having a smaller protruding length is bent and formed on the other 21b of the inner surface 25 of the large-length first connecting piece 11, and 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.

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

The base member 4 is constructed 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 Figures 1 to 4. The base piece 7, which is fixed to the bottom surface portion 29 of the base member 3 with a screw, is bent at both side edges 9, 9 of the base piece 7 in the entrance/exit opening 2 in the entrance/exit direction F (Figures 2 to 4) to form the short-length first connecting piece 10 with a small protruding length and the large-length first connecting piece 11 with a large protruding length, which protrude toward the entrance/exit opening 2 side. The thickness is set to, for example, 2.3 mm. In Figures 1 to 4, the short-length first connecting piece 10 is arranged on the side where the hinged door 6 is attached, and the large-length first connecting piece 11 is arranged on the opposite side to the side where the hinged door 6 is attached.

The frame member 5 is constructed by bending a single metal plate (e.g., a steel plate) to extend 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 is formed by bending the side pieces 16, 16 of equal length that protrude toward the base member 4 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 when viewed in the entrance/exit direction of the entrance/exit opening 2, and the inner pieces 20, 20 of equal length that protrude in the opposite direction 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 leading edge 21a of one of the inner pieces 20, 20, overlapping the leading end portion 23 of the outer surface 22 of the small-length first connecting piece 10 and screw-fixed to the small-length first connecting piece 10. The small-length second connecting piece 27 is bent and formed on the leading edge 21b of the other of the inner surfaces 25 of the large-length first connecting piece 11 and screw-fixed to the large-length first connecting piece 11. In this embodiment, the door stop 28 of the hinged door 6 is bent and formed on the frame member main body 13.

As shown in FIG. 5, the base piece 7, the long first connecting piece 11, and the long second connecting piece 24 have screw holes 36 pre-formed at the screw fixing locations, and as shown in FIGS. 2 to 4, the screw fixing is performed using drill screws 37 inserted through the screw holes 36.

Figures 6 and 7 show the process of attaching the frame member 5 to the base member 4, which is fixed with screws to the base material 3. The frame member 5 is moved laterally (in the direction indicated by the arrow in Figure 6) from the left side of Figure 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 Figure 7. When overlapping in this way, appropriate inward and outward adjustments are made.

Such lateral movement is possible because the protruding length of the short-length first connecting piece 10 is set small, which prevents the short-length second connecting piece 27, which moves in the lateral direction, from colliding with the short-length first connecting piece 10.

After the lateral movement is complete, 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. 2-4), 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. 2-4). This allows the frame member 5 to be attached to the base member 4 with the screws.

Figure 8 shows a U-shaped frame body 39 formed by connecting the upper ends 38, 38 of the left and right frame members 5a, 5a extending vertically of the entrance/exit opening 2 with an upper frame member 5b extending horizontally of the entrance/exit opening 2. The method of fixing the U-shaped frame body 39 to a U-shaped base material 4 formed by fixing the base material 4 with screws to the left and right vertical base materials 3, 3 (Figures 2-3) and the horizontal base material 3 (Figure 4) located above is the same as that explained based on Figures 6-7. That is, by moving the U-shaped frame body 39 laterally from the left side to the right side 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 making appropriate adjustments to the ingress and egress, the U-shaped frame body 39 is fixed to the U-shaped base member 4 with screws in the same manner as shown in FIGS. 2 to 4. This makes it possible to construct an ingress/egress opening 2 with high dimensional accuracy and high strength with good workability.

After the U-shaped frame body 39 is attached by screws in this manner, the wall board 18 is abutted against the inner piece 20 on both sides of the U-shaped frame body 39 as viewed in the ingress/egress direction F, as shown in Figures 2 to 4, and appropriately fixed to the base material 3 by screws. Since the large-length second connecting piece 24 and the small-length second connecting piece 27 are continuously provided in the vertical and horizontal directions, the entire edge portion 41 of the wall board 18 is supported from the back side. Therefore, the wall board 18 is stably supported at the edge portion 41 as well, and a wall body 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 is in contact with the base piece 7.

The present invention is by no means limited to the above examples, and it goes without saying that various design modifications are possible within the scope of the claims. One example is as follows.

(1) Figure 9 shows an opening part forming device 1 for a structure in which the base material 3 is made of wood, and the 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.

(2) The entrance opening 2 may be opened and closed with a sliding door or a folding door. In this case, the door stop 28 in Figures 2 and 3 is not provided.

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

(4) In the present invention, the entrance/exit opening 2 may be configured as an entrance/exit for a structure, or as an entrance/exit for a structure such as a garage.
