Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water stop structure of a vertical joint between outer wall panels.
[0002]
[Prior art]
The water stop between the adjacent left and right outer wall panels is conventionally done after the outer wall panel is erected, and the outer wall surface material of the adjacent outer wall panel is wet-sealed, or between the outer wall surface materials is dry. This was done by fitting a gasket.
[0003]
[Problems to be solved by the invention]
However, with the above-mentioned water-stopping method, water installation will be troublesome because water will enter the building unless the water-stopping work is done immediately after the construction of the outer wall panels. There was a problem of being.
[0004]
In view of the conventional problems as described above, the present invention can make the part between the adjacent left and right outer wall panels water-stopped at the same time by constructing the outer wall panels, so that construction on the site is easy. It is an object of the present invention to provide a waterstop structure for a vertical joint between outer wall panels that can be made.
[0005]
[Means for Solving the Problems]
The above-mentioned problem is that a pillar of a building frame is provided behind the left and right outer wall panels, and a vertical water stop spacer extending in the vertical direction is provided on the vertical panel frame on the side of each outer wall panel. The spacer is sandwiched between the vertical panel frame and the column so as to be in a water-stopped state, the vertical panel frame and the column are separated from each other, and a drainage space extending in the vertical direction is formed between the spacers. And,
In each of the outer wall panels, the problem is solved by the water-stopping structure of the vertical joint between the outer wall panels, wherein the space between the vertical panel frame and the outer wall surface material is stopped by a second water-stopping material.
[0006]
In this water stop structure, the adjacent left and right outer wall panels consist of a water stop with a second water stop material between the vertical panel frame and the outer wall surface material. For example, at the same time, the spacers of each outer wall panel are in contact with the back pillar in a water-stopped state, and a drainage space extending in the vertical direction between the spacers is formed, so that the portion between the outer wall panels is in a water-stopped state. It is no longer necessary to immediately stop the water between the outer wall panels after erection of the panels, and the construction at the site can be facilitated.
[0007]
In the water stop structure, the outer wall surface material of each outer wall panel is composed of a plurality of face members, and the second water stop material is formed of a waterproof sheet, and the waterproof sheet is provided in each outer wall panel. It is preferable that the back side of the material is covered and connected to the spacer in a water-stopped state between the outer wall surface material and the vertical panel frame.
[0008]
In this case, the waterproof sheet can prevent water that has entered the interior through the face materials constituting the outer wall material of each outer wall panel from further entering the indoor side. Since the structure has a function of stopping water between the wall surface material and the vertical panel frame, it is possible to stop water between the outer wall surface material and the vertical panel frame with a simple structure. In addition, this waterproof sheet is directly connected to the spacer in a water-stopped state between the outer wall surface material and the vertical panel frame, so that water penetration between the outer wall surface material and the vertical panel frame is ensured. It can be blocked with high sexuality.

The spacer 5 is attached. The spacer 5 is made of, for example, a hydrophobic urethane foam.
[0012]
On the other hand, the other side of the angle member constituting the vertical panel frame 4 is directed in the indoor direction, and a face material holding hardware 7 is attached to the other side via an auxiliary material 6. The outer wall surface material 3 is held by the vertical panel frame 4 by holding the upper and lower edges of the wall surface material 3. In the present embodiment, although the outer wall surface material 3 is not shown in detail, the outer wall surface material 3 is composed of a plurality of surface materials arranged in an adjacent state in the vertical direction, and the upper and lower edges of each surface material are the surface material holding hardware 7. The structure is held by
[0013]
Further, as shown in FIG. 3, a waterproof sheet 8 as a second water stop material, for example, a moisture permeable waterproof sheet, is provided on the back side of each outer wall panel 1. Covers the back side and stops water entering the inside through the face materials constituting the outer wall surface material 3, and the spacer 5 is in a water-stopped state between the outer wall surface material 3 and the vertical panel frame 4. It is connected to.
