Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint cover for buildings that covers joints formed between adjacent buildings.

Conventional joint covers of this type have difficulty following the shaking when adjacent buildings shake in different directions due to earthquakes, strong winds, etc. There was a risk that the building could be damaged or the joint cover itself could be damaged. In order to solve this problem, we filed Utility Model Application No. 53-36627. As shown in FIG. 1, the application proposes a method in which a joint cover is divided into two parts, first and second cover plates a and b, and one side edge of both of the divided cover plates is overlapped by a predetermined amount. and the other side edges are rotatably attached to fixtures c fixed to mutually adjacent buildings,
In order to maintain the overlapping state of both cover plates, a cover plate support member d is attached to one of the fixtures, and the first cover plate a is placed between the second cover plate b and the second cover plate b.
It is structured to sandwich the . However, with this configuration, there is a problem in terms of wind pressure resistance.In particular, when the width of the joint part becomes wider due to the increase in the height of buildings, and the cover plates a and b become wider, a large wind pressure is applied and both cover plates The cover plate rotates as shown by the two-dot chain line in Figure 1, and as a result, the problem remains unsolved that the cover plate is plastically deformed into a large curve.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a joint cover for buildings that can follow the different shaking of buildings and has high wind pressure resistance.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

First, in FIG. 2, reference numerals 1 and 2 are a first building and a second building that are adjacent to each other, and these are close to each other, and a joint portion 3 of a predetermined width is formed between them.
Reference numerals 4 and 5 denote a first support body and a second support body made of aluminum or stainless steel, which are positioned on both the left and right sides of the joint 3 to support the outer wall surface of each of the first and second buildings 1 and 2. It is attached to the wall and extends vertically along its outer wall surface. The supports 4 and 5 are formed into a substantially L-shaped cross section, and fixing plate portions 4a and 5a forming one side are attached to screws 7 to hole-in anchors 6 implanted in the outer wall surfaces of the respective buildings 1 and 2. It is fixed in place. The fixing plate portions 4a, 5a of each of the supports 4, 5 are integrally provided with a vertically extending pivot portion 8 having a substantially C-shaped cross section. Note that the partition plate portions 4b and 5b forming the other side of each support body 4 and 5 are as follows:
This is to prevent the mortar from flowing into the fixed plate parts 4a, 5a when finishing the outer wall surfaces of the buildings 1, 2 with mortar 9. Reference numerals 10 and 11 designate a vertically elongated first connecting body and a second connecting body formed by extrusion molding or the like of aluminum.
0b to 10d, 11b to 11d, and has a substantially E-shaped cross section with auxiliary plate parts 10e and 11e flush with the holding plate parts 10d and 11d on the other side, and the outer surfaces of the holding plate parts 10d and 11d have A rotating protrusion 12 with a circular cross section extending vertically is integrally provided. Such first and second connected bodies 10, 11
By fitting the rotating protrusion 12 into the pivot portion 8 of each of the supports 4 and 5,
It is rotatably mounted on the Reference numerals 13 and 14 denote a first cover plate and a second cover plate which are vertically elongated and made of aluminum or stainless steel. Plate parts 10b, 11b and auxiliary plate part 1
0e and 11e with screws 15, and the other side is extended toward the other building to form a predetermined amount of gap 16 therebetween. Note that the other sides of both cover plates 13 and 14 are bent into a substantially F-shape. Reference numeral 17 denotes a reinforcing body, which consists of two long links 18 and 19 and two short links 2 made of aluminum or stainless steel, etc., as shown in Fig. 3.

Both ends of the cover plates 13 and 14 can be rotated in the vertical direction along the plate surfaces of the cover plates 13 and 14, and when the first and second buildings 1 and 2 swing in the left and right directions, the reinforcing body 17 is free to move in the left and right directions. expands and contracts. In this case, short link 2
0 and 21 are connected to the long links 18 and 19 approximately in the center in the longitudinal direction, and both short links 2
The shaft 24 connecting the shafts 0 and 21 is always located at the center of the straight line connecting the shafts 26, regardless of the expansion and contraction of the reinforcing body 17. The reinforcing bodies 17 as described above are provided in multiple stages in the vertical direction between the two connecting bodies 10 and 11. Reference numeral 27 denotes a vertically elongated third cover plate made of aluminum or stainless steel, and the third cover plate 27 overlaps the first and second cover plates 13 and 14 by a predetermined amount on both left and right sides. The first cover plate 13 is arranged between the cover plates 13 and 14 and the reinforcing body 17 in this manner.
and the second cover plate 14 is closed. The third cover 27 is attached to a shaft 24 that connects the short links 20 and 21 of the reinforcing body 17 together with a holding frame 28 facing the reinforcing body 17 side. And the first cover plate 13 and the second cover plate 1
4 are connected to the reinforcing body 17 via the first connecting body 10 and the second connecting body 11, respectively, and rotate in a direction to maintain a state parallel to the reinforcing body 17 against the longitudinal shaking of the building. Due to this regulation, the third cover plate 28 is always connected to the first cover plate 13.
and is configured to maintain the overlapping state with the second cover plate 14. In addition, 29 is both connected body 1
This is a sheet-like sealing member installed between the fitting grooves 10f and 11f formed at the tips of the holding plate parts 10d and 11d of 0 and 11. It is made of neoprene rubber or the like so that it can be expanded and contracted, and it prevents rainwater, etc. This is to prevent it from penetrating into the joint portion 3. Further, reference numerals 30 and 31 indicate highly flexible materials filled in the gaps between the mortar 9 and the supports 4, 5 of the buildings 1, 2 and the gaps between the supports 4, 5 and the connecting bodies 10, 11. It's a sticker.

In this embodiment configured as described above, when both the buildings 1 and 2 shake differently in the vertical direction due to an earthquake or a strong wind, the first cover plate 13 and the second cover plate 14 are connected to the buildings 1 and 2, respectively. 2 and move up and down. At this time, both ends of the reinforcing body 17 are attached to the shaft 26.
The third cover plate 27 rotates in the vertical direction around the center, and is tilted as shown in FIG. Slide relatively up and down. Incidentally, even when both buildings 1 and 2 settle unevenly, each member moves in the same manner as described above.

Furthermore, when both buildings 1 and 2 swing differently in the left-right direction, the first cover plate 13 and the second cover plate 14 move in the left-right direction following the buildings 1 and 2, respectively, as shown in FIG. . On the other hand, the reinforcing body 17 expands and contracts in the left-right direction as both buildings 1 and 2 swing in the left-right direction, and the first cover plate 13 and the third cover plate 27 attached to the reinforcing body 17 The two cover plates 14 relatively slide in the left and right direction while maintaining their overlapping state.

Furthermore, when both buildings 1 and 2 swing differently in the front-back direction, the first cover plate 13 and the second cover plate 14 are in a parallel state with the reinforcing body 17, and thus with the third cover plate 27, as shown in FIG. While maintaining the overlapping state, the connecting bodies 10 and 11 rotate around the rotating protrusions 12, respectively, and follow the swinging of both buildings 1 and 2 in the front-rear direction.

By the way, especially during a storm, each cover plate 13,1
On April 4, 27, a large wind pressure was applied. however,
A reinforcing body 1 is provided between the connecting bodies 10 and 11 corresponding to the rotation bases of the first cover plate 13 and the second cover plate 14.

7, and there is no risk of the cover plate being deformed.

Next, FIGS. 7 and 8 show other examples of different configurations of the reinforcing body. First, the reinforcing body 31 shown in FIG. A pinion 35 is inserted into and supported by the shaft 36 and engages with rack portions 32a and 33a formed in the case 34 on the rods 32 and 33, respectively.
The end portions of the rods 32 and 33 are connected to the connecting bodies 10 and 11 by a shaft 37, and a third cover plate 27 is attached to the shaft 36 of the pinion 35. Further, the reinforcing body 38 shown in FIG. A long hole 44 extending in the horizontal direction is formed in the holding body 41 and protrudes from each of the rods 39 and 40.
A pin 45 protruding outward from the pivot plate 42 is inserted into a longitudinally extending elongated hole 46, and the tips of the rods 39, 40 are connected to each connecting body 10, 11 by a shaft 47. Shaft 4 of the rotating plate 42
3, a third cover plate 27 is attached to the third cover plate 27.

As explained above, the present invention rotatably attaches the first cover plate and the second cover plate to supports fixed to adjacent buildings, and also connects both ends of the expandable reinforcing body to the first cover plate. Since the third cover plate is rotatably connected to the plate and the second cover plate, and the third cover plate is attached to the reinforcing body to close the gap between the first cover plate and the second cover plate, both buildings Each cover plate can slide or rotate relative to each other in response to different shaking in the vertical, horizontal, and front-back directions, and can follow the shaking of both buildings, preventing damage to the building or cover plate, etc. It has excellent durability. Moreover, the wind pressure applied to each cover plate is absorbed by the reinforcing body, so even if each cover plate becomes wider as buildings become taller, it will be able to withstand large wind pressure and prevent deformation. That will no longer be the case.
