Description

[Detailed description of the invention] This invention relates to a joint cover that is attached across a predetermined gap (hereinafter simply referred to as a joint) between the inner or outer walls of two adjacent buildings and covers the joint. .

The purpose of this invention is to prevent damage to the cover plates that make up the joint covers even when both buildings shake in different directions due to earthquakes or strong winds, and to prevent damage to the cover plates that form the joint covers. To provide a joint cover having excellent durability and capable of always satisfactorily closing a joint part that has been damaged.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, numerals 1 and 2 are two adjacent buildings separated by a joint S, and their inner wall surfaces IA and IB are on the same plane.

Reference numeral 3 denotes a mounting member having a Z-shaped cross section that is fastened via screws 4 to the wall corner of the building 1 on the left side of the drawing, and the supporting piece 3A at the tip thereof is attached to the side wall surface 1B of the building. A long screw-shaped connecting rod 5 for attaching a cover plate 9, which will be described later, is loosely inserted through the center of the supporting piece 3A.

Further, a washer 6 for a spring receiver is inserted through the tip of the shaft portion 5A of the connecting rod 5, and a nut 7.7 is screwed thereto. A spring 8 made of a compression coil spring is interposed in the shaft portion 5A of the connecting rod 5 between the two.

Reference numeral 9 denotes a cover plate made of a metal plate such as a stainless steel plate or an aluminum plate that covers the joint portion S, and is mounted and supported across the joint portion S via the connecting rod 5.

That is, an inner plate 10 is attached to the inner surface of the cover plate 9 with screws 1.
A recess 11 having an inverted U-shape in cross section is formed on the left side of the inner plate 10, which is fastened through the inner plate 10 and the connecting rod 5. The shaft portion 5A of the connecting rod 5 is inserted through the connecting rod 5, and the head portion 5B of the connecting rod 5 is engaged to be connected and supported.

Further, both side edges of the inner plate 10 are bent oppositely to have an arcuate cross section along the inner wall surfaces of both buildings, and holding pieces 10A and 10B are formed.
are formed, respectively, while outside of the holding pieces 10A and 10B, both side edges of the cover plate 9 are bent and held in an inverted cross-sectional shape along the inner wall surfaces IA and 2A of both buildings. Pieces 9A and 9B are formed, respectively.

Then, the holding pieces 9A and 9B of the cover plate 9 and the inner plate 10
Between the holding piece 10A and the IOB, there is a flexible synthetic resin,
Seal members 13 and 14 each made of an elastic member such as synthetic rubber are interposed.

The sealing members 13 and 14 have distal ends that are connected to both holding pieces 9.
It protrudes from between A, 10A, 9B, and 10B, and due to the biasing force of the spring 8, the inner wall surface IA of both buildings
, are pressed against IB.

Subsequently, the operation of this example configured as described above will be explained.

If both buildings 1 and 2 shake in different directions due to an earthquake or strong wind, for example, as shown in Figure 1, one building 1 may be swayed relative to the other building 2. R, R
When the cover plate 9 swings in the direction of the arrow, the cover plate 9 is still supported via the connecting rod 5 to the mounting member 3 of one of the buildings 1, and the cover plate 9 is supported by the biasing force of the spring 8.
The sealing members 13 and 14 on both side edges are pressed against the inner wall surfaces I A and 2A of both buildings to seal the joint S.

Further, as shown in FIG. 2, when one building 1 swings relative to the other building 2 in the direction of the arrow P shown in the figure, the cover plate 9 is moved by the biasing force of the spring 8 into the mounting member. The support piece 3A of the cover plate 9 is tilted and supported as shown in the figure via a connecting rod 5 that is loosely fitted, and both seal members 13 and 14 of the cover plate 9 are attached to the inner wall surfaces IA and 2A of both buildings. They are pressed together to seal the joint S.

Further, as shown in FIG. 3, when one building 1 swings relative to the other building 2 in the direction of the arrow Q shown in the figure, the cover plate 9 is moved by the biasing force of the spring 8 as described above. , is tilted and supported in the opposite direction to the above-mentioned direction with respect to the mounting member 3 via the connecting rod 5, and both seal members 13 and 14 of the cover plate 9 are pressed against the inner wall surfaces of both buildings to form the joint portion S. is sealed.

In this way, in this example, even when both buildings shake in different directions, the cover plate 9 is not damaged and can straddle the joint S formed between the two buildings. is retained.

In the above example, joint covers were attached to the inner wall surfaces IA and 2A of both buildings 1 and 2 adjacent to each other across the joint, spanning the joint S. It is also possible to attach a joint cover to the wall surface, spanning the joint as described above, and in this case, it is also possible to prevent infiltration of rainwater and the like.

That is, this invention consists of a mounting member that is fixed to the wall end of one of the two buildings that are adjacent to each other across a joint, and a connecting rod that is movably attached by being loosely fitted to this mounting member. a cover plate that is attached to the outer end of the connecting rod and covers the joint portion; and a cover plate that is interposed between the mounting member and the connecting rod and biases the cover plate toward the wall surfaces of both buildings. This joint cover is characterized in that it also includes springs that press both ends of the cover plate into pressure contact with the walls of both buildings.

Therefore, if both buildings shake in different directions due to an earthquake or strong wind, the connecting rod can move relative to the mounting member, and the cover plate attached to the outer end of this connecting rod can move against both buildings. can be followed.

Therefore, the cover plate, the connecting rod, and the mounting member can be prevented from being damaged, resulting in excellent durability.

Moreover, the end edges of the cover plate are brought into pressure contact with the wall surfaces of both buildings by the biasing force of the spring, so that the joint portion can always be well sealed.
