Description

[Detailed explanation of the idea] This invention relates to a joint cover.

When constructing a three-story prefabricated house in a residential area, it is difficult to assemble scaffolding, so there are some models that allow joint covers between exterior wall panels to be constructed from the inside. 1 and 2 show a joint structure formed using such a conventional joint cover A. That is, a joint cover A is prepared in which a pair of elastic watertight materials 2 are disposed along both sides of the back side of a groove-shaped joint cover main body 1 and a threaded rod 3 is erected in the middle thereof, and adjacent outer wall panels 4 and 5 are prepared. Place the joint cover main body 1 on the front side of the joint space 6 formed between the two, pass the threaded rod 3 through the joint space 6, pass the washer 7 through the threaded rod 3 from the back side of the joint space 6, and tighten with a nut 8. By this,
The washers 7 are attached to the panel frames 4a of the outer wall panels 4 and 5,
The elastic watertight material 2 is attached to the indoor surfaces 4c, 5c of the outer wall panels 4, 5, and the outdoor surface panels 4b, 5b of the outer wall panels 4, 5
comes into elastic contact with the edge of the However, there was a problem in that a portion 2a of the elastic watertight material 2 protruded from between the ends of both sides of the joint cover body 1 and the outdoor surface boards 4b and 5b, impairing the aesthetic appearance. In addition, the elastic watertight material 2 is attached only to both sides of the joint cover main body 1, so that the contact area with the outdoor surface plates 4b, 5b is small, and furthermore, due to capillary action, rainwater flows between the elastic watertight material 2 and the outdoor surface plates 4b, 5b. Since the water enters the joint space 6 side through the contact surface, there is a problem in that sufficient waterproof performance cannot be obtained.

Therefore, the purpose of this invention is to provide a joint cover that is excellent in aesthetic appearance and rain protection performance.

An embodiment of this invention will be described with reference to FIGS. 3 and 4. That is, as shown in Figure 3,
This joint cover B has a substantially groove-shaped cover main body 9 with a Fuji-shaped projecting strip 9b protruding from the center of the back surface of the web 9a and both side pieces 9c expanding outward, and a band-shaped cover on the back surface side of the web 9a. An elastic watertight material 10 is attached so that the rear surface 10a projects outward from the tips of the both side pieces 9c, and both side surfaces 10b are spaced apart from the inner surfaces of the both side pieces 9c, and a plurality of threaded rods 11 ( Only one is shown in Figure 3)
are provided protruding from the center of the back surface of the web 9a at predetermined intervals in the longitudinal direction, and penetrate the band-shaped elastic watertight material 10. In this case, the threaded rod 11 is
The screw head 11a is clamped and fixed between the web 9a of the cover body 9 and the Fuji-shaped protruding strip 9b.

To install this joint cover B, as shown in FIG. 4, the cover main body 9 is placed on the outdoor side of the wall panels 4 and 5, and the threaded rod 11 is passed through the joint space 6 between the wall panels 4 and 5. At the same time, both sides of the watertight material 10 are placed in contact with the surface edges of the surface plates 4b and 5b of the wall panels 4 and 5, and the washer 7 is attached to the threaded rod 11 from the indoor side.
Through the panel frame interior surface 4c of the wall panels 4 and 5,
5c, then screw the nut 8 onto the threaded rod 11, and tighten the nut 8 until the tips of the side pieces 9c of the cover main body 9 abut against the surface plates 4b, 5b of the wall panels 4, 5. This brings the elastic watertight material 10 into pressure contact with the surface plates 4b and 5b.

In this way, both side surfaces 10b of the elastic watertight material 10 are separated from the inner surfaces of the both side pieces 9c of the cover main body 9 to form an elastic watertight material expansion space 12 between them, as shown in FIG. Even after the joint cover B is attached to the wall panels 4 and 5, the elastic watertight material 10 can be prevented from protruding from between the side pieces 9c and the wall panels 4 and 5, and the external beauty of the building can be improved. In addition, since the elastic watertight material 10 was formed into a band shape and was continuously attached to the back side of the web 9a of the cover body 9, the rear surface 10a of the elastic watertight material 10 and the surface plates 4b, 5b of the wall panels 4, 5 are connected. The contact area is also increased compared to the conventional example, and as a result, rain protection performance can be improved. Moreover, after the joint cover B is installed, rainwater that has entered from between the both side pieces 9c and the panel surface plates 4b and 5b due to capillary action will be cut off in the space 12 and will no longer enter the interior. It is possible to improve the rain protection performance. Furthermore, since the screw head 11a of each threaded rod 11 is clamped and fixed between the web 9a of the cover main body 9 and the Fuji-shaped protruding strip 9b on the inner surface thereof, the threaded rod 11 does not penetrate through the cover main body 9. Watertightness is improved, and the screw head 11a is not visible from the outside, giving a good appearance.

As described above, the joint cover of this invention includes a substantially groove-shaped cover main body with both sides expanded outward;
A band-shaped elastic watertight material is attached to the back surface of the web of the cover main body and has both sides separated from the inner surface of the both sides, and a band-shaped elastic water-tight material is attached to the inner surface of the web of the cover main body and is protruded at predetermined intervals in the longitudinal direction from the center of the inner surface of the web of the cover main body. Equipped with multiple threaded rods that penetrate watertight material, it has excellent aesthetics and rain protection performance. In addition, since the screw head of each threaded rod is clamped and fixed between the web of the cover body and the Fuji-shaped protruding strip on its inner surface, the threaded rod does not penetrate the cover body, improving watertightness. The screw head is not visible from the outside and has the effect of looking good.
