CONSTITUTION:The vertical frames la and lateral frames of an outer wall panel 1 are formed into a groove form opened inward, and an outer wall throating 2 and an open cell throating material 3 are provided on the horizontal joint between the upper frame 1a of the lower panel 1 and the lower frame 1a of the panel 1 so as to be orthogonal to the vertical joint between the laterally arranged panels 1. The throating 2 is placed on the upper surface of the upper frame 1a of the lower panel 1, a suspended piece 2a and a raised part 2b are provided on the outdoor side and the indoor side, respectively, and a watertight material 4 is mounted between the suspended piece 2a and the facing material 1b of the panel 1. The throating material 3 is placed on the upper surface of the throating 2 and mounted in the state compressed by the upper side panel 1. Thus, the watertight material 3 easy to expand and contract together with the throating 2 is continuously provided between the upper and lower frames 1a, whereby watertightness can be ensured.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of an outer wall.

[0002]

2. Description of the Related Art In a conventional joint structure, as shown in FIGS. 5 to 7, the upper and lower frames 50a of the outer wall panel 50 are h.
In the case of the shape, the L-shaped metal 51 is fixed to the upper frame 50a of the lower outer wall panel 50 forming the horizontal joint together with the outer wall drainage 53, and the outer wall drainage 53 and the lower frame 5 of the upper outer wall panel 50 are fixed.
The watertight materials 52, 52 were interposed between the 0a and 0a. A watertight material 54 is also provided between the outer wall drain 53 and the outer surface of the outer wall panel 50.
Is installed. The configuration of the vertical joints of the outer wall panel 50 is shown in FIG. An outer wall joiner 55 is attached across the outer surfaces of the outer wall panels 50, 50 arranged side by side. Two recesses are formed on the back side of the outer wall joiner 55,
An open-cell watertight material 56 is mounted in this.

[0003]

However, when the upper and lower frames 50a of the outer wall panel 50 are changed to the groove shape, the above construction cannot deal with the lateral joint. Therefore, an object of the present invention is to provide a joint structure capable of ensuring water tightness when the upper and lower frames of the outer wall panel are groove-shaped.

[0004]

The joint structure of the present invention comprises:
Outer wall panels are arranged side by side vertically and horizontally, and in a joint structure in which a vertical joint between the outer wall panels arranged side by side is provided with a watertight material and an outer wall joiner covers the watertight material, the upper and lower frames of the outer wall panel face inward. It has an open groove shape, and is characterized in that an outer wall drainer and a continuous cell watertight material are provided in the horizontal joint between the upper and lower frames so as to be orthogonal to the vertical joint.

[0005]

According to the construction of the present invention, when the upper and lower frames of the outer wall panel forming the lateral joint are groove-shaped and open inward, the continuous cell watertight material which is easily expanded and contracted together with the outer wall drain is connected between the upper and lower frames. The watertightness can be secured by providing the above. In this case, no hardware or the like is required to attach the open-cell watertight material, and the construction becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A joint structure according to a first embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 is an outer wall panel, which is arranged in parallel in the vertical and horizontal directions. Upper and lower frames 1a of this outer wall panel 1
The left and right frames (see FIG. 7) are groove-shaped and open inward. A vertical joint between the outer wall panel 1 in which the outer wall drainer 2 and the open-cell drainage material 3 are arranged side by side in a horizontal joint between the upper frame 1a of the lower outer wall panel 1 and the lower frame 1a of the upper outer wall panel 1. It is provided so as to be orthogonal to.

The outer wall drainer 2 is made of vinyl chloride steel plate or the like and is placed on the upper surface of the upper frame 1a of the lower outer wall panel 1. Also, the hanging piece 2a on the outdoor side and the rising portion 2 on the indoor side.
b are formed respectively. A watertight material 4 is attached between the hanging piece 2a and the exterior material 1b of the lower outer wall panel 1,
The rising portion 2b is brought into contact with the outer surface of the flange of the lower frame 1a of the outer wall panel 1 on the upper side. The open-cell watertight material 3 is made of a material that can easily expand and contract, is mounted on the upper surface of the outer wall drainer 2 and is attached in a compressed state by the upper outer wall panel 1. The watertight material 4 is also an open cell.

Further, a closed-cell watertight material 5 is provided in the vertical joint. The closed-cell water-tight material 5 is placed on the open-cell water-tight material 3, and the outer exposed portion is covered with an outer wall joiner 6. The lower end of the outer wall joiner 6 extends to the upper end of the outer wall drainer 2. In this embodiment, in the case where the upper and lower frames 1a of the outer wall panel 1 forming the horizontal joint are in the shape of a groove having an inward opening, the continuous wall watertight material 3 which can easily expand and contract together with the outer wall drain 2 is continuously provided between the upper and lower frames 1a. Water tightness can be secured by providing it. In this case, no metal or the like is required to attach the open-cell watertight material 3, and the construction becomes easy. In addition, the vertical joint is the same as in FIG.
6 is mounted inside the back surface of the outer wall joiner 55. Even when the upper and lower frames of the outer wall panel 1 are changed to the groove shape as described above, the scaffold-free dry joint construction method can be realized.

The joint structure of the second embodiment is shown in FIGS.
Shown in. That is, the sealing material 7 is provided only at the joint intersection. The sealing material 7 is provided adjacent to the open-cell watertight material 3 on the indoor side of the horizontal joint. Therefore, the water tightness is further improved. Other configuration effects are the first
It is similar to the embodiment of.

[0010]

According to the joint structure of the present invention, in the case where the upper and lower frames of the outer wall panel forming the lateral joints are groove-shaped and open inward, the open-cell watertight material which easily expands and contracts together with the outer wall drain is provided between the upper and lower frames. Watertightness can be secured by continuously providing the above. In this case, no hardware or the like is required to attach the open-cell watertight material, and the construction becomes easy.
