Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a building wall suitable for forming an outer wall of a building.

[Prior art] When constructing the exterior wall of a building by attaching panels to a steel frame, the panels are made of, for example, gypsum board, so if they are left as they are, rainwater may enter the building through the panels or through gaps between the panels. There is a possibility that For this reason, waterproof paint is sprayed on the outside surfaces of the panels, and silicone caulking is applied between the panels.

However, when constructing a new building close to a neighboring building, the space between the building and the neighboring building is too narrow for workers to get into the space. You may not be able to perform work such as applying caulk.

[Object of the Invention] An object of the present invention is to provide a wall of a building that does not require spraying waterproof paint onto the panels or applying caulk between the panels.

[Summary of the Invention] The present invention comprises panels that are arranged adjacent to each other vertically and horizontally, and a waterproof board that is attached to the outer surface of the panel so as to cover it, and a waterproof board that extends vertically on one side of the waterproof board. A concave plug-in part that extends narrower on the lower end side than the upper end side is bent, and an insertion part is bent on the other side, so that the waterproof plates of the left and right adjacent panels are connected to each other. By inserting the insertion part inside the inserted part of the other waterproof board, the waterproof boards of the vertically adjacent panels are connected, and the inserted part of the upper waterproof board is connected to the inserted part of the lower waterproof board. The lower end of the upper waterproof plate is overlapped with the front side of the upper end of the lower waterproof plate so as to fit inside the lower waterproof plate.

[Embodiment of the Invention] An embodiment of the present invention will be described below based on the drawings. Figure 6 shows the entire building, and the walls that make up the outer wall are panel 1 as shown in Figure 5.
are arranged adjacent to each other vertically and horizontally, and a waterproof plate 2 is attached to the outer surface of each panel 1.

The panel 1 is made of aerated concrete, generally called ALC, and has a vertically elongated rectangular shape. As shown in FIG. 1, a recessed step 3 is formed on one side of the left and right edges of the outer surface of the panel
are formed therein, and substantially semicircular grooves 4 are formed on both left and right side surfaces.

On the other hand, the waterproof plate 2 is made of metal such as aluminum, and has a rectangular shape that is slightly larger than the panel 1. On one side of the left and right sides of the waterproof board 2 corresponding to the stepped part 3 of the panel 1, a mounting part 5 is bent toward the back side so as to be substantially perpendicular to the surface of the waterproof board 2. is formed,
Small holes 6 are formed intermittently in this attachment portion 5. Reference numeral 7 denotes a concave insertion portion formed on the waterproof plate 2 near the mounting portion 5, which is separated from the mounting portion 5 by a substantially U-shaped protrusion 8, and is It is separated from the surface of 2 by a substantially U-shaped protrusion 9, and is laterally opened through a gap between both protrusions 8 and 9. and,
This inserted part 7 extends in the vertical direction as shown in FIG.
For example, the dimensions A, B, and C at the lower end of the waterproof plate 2 are smaller than those at the upper end, so that the gap dimension C between 9 and 9 becomes smaller as it goes downward.
It is formed so that it is approximately twice as small as the plate thickness. Reference numeral 10 denotes an insertion portion formed on the other side of the waterproof plate 2, which is approximately L-shaped and separated from the surface of the waterproof plate 2 by a bent portion 11 bent at a substantially right angle. The vertical lengths of the panel 1 and the waterproof board 2 are set to be equivalent to the height of one floor of the building.

FIG. 4 shows the installation structure of the panel 1 on the steel frame of a building. In this figure, 12 is a steel frame provided on the outermost side of the part corresponding to the floor of each floor of the building. A support plate 13 is fixed to this by welding or the like at a predetermined pitch interval. This support plate 13 is for supporting the ends of adjacent panels 1 on the left half and the right half, and has a relatively large hole 14 in the center and small holes 15 on both sides of this hole 14. A reinforcing bar 16 of a predetermined length is fixed to the reinforcing bar 14 by welding or the like so as to protrude vertically with equal length.

Next, the procedure for attaching the panel 1 and the waterproof board 2 to the steel frame and constructing the wall will be explained. First, one panel 1 is placed between the four support plates 13 on the top, bottom, left and right, which are fixed to the steel frame 12 on each floor.
A nail 17 is driven into the panel 1 through one of the small holes 15 on both sides of the panel 3 to fix it. Next, the waterproof board 2 is placed on the outer surface of the panel 1 so as to cover it, and the inserted part 10 is placed on the stepped part 3 of the panel 1.
Attach the mounting part 5 to one side of the panel 1 so that it is located inside. Then, nails 18 are driven into the panel 1 through the small holes 6 of the attachment part 5 to fix the waterproof board 2 to the panel 1. In this way, one panel 1
After installing the panel 1 and attaching the waterproof board 2 thereto, place the next panel 1 next to and adjacent to the previously installed panel 1, and attach the panel 1 to the supporting board in the same manner as described above. Fixed at 13. After this,
Move the waterproof plate 2 from the side of the panel 1 that was attached later to the panel 1 that was attached earlier so as to follow the outer surface of the panel 1, and then insert the insertion part 10.
is inserted into the inserted portion 7 of the waterproof plate 2 previously attached through the gap between the protrusions 8 and 9, and is coupled.
Incidentally, mortar 19 is poured into a substantially circular hole formed by the groove 4 between adjacent panels 1. As described above, the panels 1 are attached vertically and horizontally, and each time one panel 1 is attached, the waterproof plate 2 is attached to the panel 1 so as to cover it.

In this case, the panels 1 are installed sequentially from the first floor to the upper floors, and the waterproof panels 2
The insertion part 7 of the upper waterproof plate 2 is fitted inside the inserted part 7 of the lower waterproof plate 2, and the lower end of the upper waterproof plate 2 is placed downward as shown in FIG. It is attached so as to overlap the surface of the upper end of the waterproof board 2. Therefore, at both the upper and lower end portions of the panel 1, four waterproof plates 2 overlap each other on both the left and right sides, as shown in FIG. Even if the four waterproof plates 2 overlap in this way, the width dimensions A and B of the inserted part 7 and both protrusions 8 and 9
Since the interval dimension C between the waterproof plates 2 is formed so as to become smaller as it goes downward, it will not become impossible to connect the waterproof plates 2 to each other.

According to the above configuration, since the outer surface of the waterproof panel 1 is covered with the waterproof board 2, rainwater does not enter the building through the panel 1. Further, the left and right waterproof plates 2 are connected to each other by inserting the insertion part 10 into the recessed inserted part 7, and the upper and lower waterproof plates 2 are connected to each other by connecting the lower end of the upper waterproof plate 2 to the lower waterproof plate. Since the boards 2 are joined to overlap with each other on the front side of the upper end, rainwater will not enter the building through the gaps between the waterproof boards 2.

In this case, in this embodiment, the protrusion 8 is particularly formed between the attachment part 5 and the inserted part 7, so even if rainwater enters the inserted part 7, the protrusion 8 will prevent the rainwater from entering the inserted part 7. Since rainwater is prevented from further intruding into the mounting portion 5 side, the intrusion of rainwater can be more reliably prevented.

In addition, in this embodiment, when the plug-in part 10 is inserted into the plug-in part 7, spaces 20 and 21 are formed on both left and right sides of the plug-in part 10 in the plug-in part 7. Even if the panels 1 move relative to each other vertically and horizontally when the object shakes, the relative movement can be absorbed by the spaces 20 and 21.

As mentioned above, since the waterproof board 2 can prevent rainwater from entering the building through the wall, waterproofing paint can be sprayed on the outer surface of the wall, or caulking can be applied to the gaps between the panels 1. There is no need to paint it in. Moreover, since the waterproof board 2 has a mounting part 5 on one side for fixing it to the side of the panel 1, after one panel 1 is mounted, the waterproof board 2 is attached to the side of the panel 1. The waterproof board 2 is installed at the end by taking the waterproof board 2 out from the unclosed area and shifting it laterally along the outer surface of the panel 1.
The work procedure is to insert the waterproof board 2 into the inserted part 7 of the panel 1, and then fix the mounting part 5 on one side of the unclosed side to the side of the panel 1 with nails 18. Therefore, the waterproof board 2 can be installed inside the building. Therefore, even if a new building is constructed very close to an adjacent building, there is no risk that the installation of the waterproof board 2 will become impossible.

In the above embodiment, the waterproof plate 2 was attached to the panel 1 after the panel 1 was attached to the steel frame 12, but in this case, the waterproof plate 2 was first attached to the panel 1, and then the waterproof plate 2 was attached to the panel 1. The panel 1 may be attached to the steel frame 12, and in this case, the attachment portion 5 of the waterproof plate 2 does not need to be particularly formed on the side portion. In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, the panels are not limited to aerated concrete, but may be made of earth and stone gypsum boards, and the waterproof panels may also be made of plastic or the like. Furthermore, the shapes of the insertion part and the inserted part are not limited to the specific shapes shown in the embodiments, and can be modified in various ways without departing from the spirit of the invention.

[Effects of the Invention] As explained above, the present invention allows the left and right waterproof plates to be connected to each other by inserting the insertion part of one waterproof plate inside the inserted part of the other waterproof plate, and also to connect the left and right waterproof plates to each other by inserting the inserted part of the other waterproof plate inside the inserted part. The waterproof plates of the panel are connected by stacking the lower end of the upper waterproof plate on the front side of the upper end of the lower waterproof plate, and the concave insertion part is wider on the lower end than on the upper end. By fitting the inserted part of the upper waterproof plate inside the inserted part of the lower waterproof plate so that the lower end of the upper waterproof plate is narrower than the upper end of the lower waterproof plate. Since the waterproof board can be stacked on the front side of the panels without any gaps, the waterproof board can prevent rainwater from entering through the panels and through the gaps between the panels. There is no need to spray paint or apply caulking into the gaps between panels, and even when constructing a new building very close to an existing building, installing waterproof panels is a breeze. This has an excellent effect in that there is no possibility that it will become impossible.
