Description

[Detailed description of the invention] This invention is a curtain that is formed by arranging a large number of panels made of metal plates or the like, or panels made of panels fitted into a pre-framed frame on one plane. Concerning the water structure between panels in a wall.

Conventionally, the method of maintaining watertightness between panels in this type of curtain wall was to fill the vertical and horizontal joints between each installed panel with caulking material, but due to aging of the caulking material, It had the disadvantage of peeling off and allowing rainwater to seep in.

The present invention provides a watertight structure that can maintain water tightness even if the caulking material peels off. Examples thereof will be described below with reference to the drawings.

In Fig. 1, a rectangular plate-shaped panel 1 made of aluminum alloy...
・Vertical joint 2... and horizontal joint 3... in the vertical and horizontal directions
Open them and arrange them in a grid pattern, each joint 2... 3...
・Each is sealed watertight.

As shown in the second figure, the vertical joint 2 is formed between the opposing panel side end surfaces 4, 4a formed by bending the left and right ends of the left and right adjacent panels 1, 1 toward the indoor side. A pair of elastic packings 5, 5a made of rubber, plastic, or the like are placed on opposing side end surfaces 4, 4a at the back of the indoor side of the vertical joint 2.
is attached over the entire vertical length of the panels 1, 1, a seal backer material 6 is inserted on the outdoor side of the elastic packings 5, 5a, and a caulking material 7 is filled on the outdoor side.

The elastic packings 5, 5a have the same shape, and include a substrate 8 fixed to the side end surfaces 4, 4a with an adhesive, a hollow seal portion 9 protruding from the intermediate portion of the substrate 8, and a A fin seal portion protruding from the indoor end and a seal bucker material receiving portion 10' protruding from the outdoor end of the substrate 8 are separated, and the seal bucker material 6 is connected to the seal bucker material receiving portion of the elastic packings 5, 5a. The hollow seal parts 9, 9 are pressed against each other, and the fin seal parts 10, 10 are overlapped in a press-contact state, thereby making the indoor side of the vertical joint 2 double. At the same time, the hollow seal portion 9 is closed within the vertical joint 2.
, 9 and the seal bucker material 6, between the hollow seal parts 9, 9 and the fin seal parts 10 and 10, and the hollow seal parts 9,
A vertical flow passage 11 that communicates in the vertical direction is formed within the hollow space of 9.

Each vertical joint 2 . . . is sealed by a watertight structure similar to that described above.

The horizontal joint 3 is formed between the upper and lower end surfaces 15, 15 3 of the panels 1, 1, which are vertically adjacent to each other, by bending their upper and lower ends toward the indoor side, as shown in the third figure. The upper end surface 15 of one panel extends inward to a position corresponding to the fin seal portion 10 of the elastic packing 5, and an upward rear wall 16 extends from the extended end.
In addition, caulking material 17 is filled on the indoor side of the horizontal joint 3, thereby forming a substantially channel-shaped horizontal flow passage 18 that communicates in the horizontal direction and is made up of the panel upper end surface 15, the rear wall 16, and the caulking material 17 within the horizontal joint 3. are doing.

Each horizontal joint 3... is sealed by a watertight structure similar to that described above.

At the intersection of the vertical joint 2 and the horizontal joint 3, each fin seal portion 1 of the elastic packing 5, 5a is inserted as shown in the fourth figure.
Guide plates 12, 12 and 13, 13 having the same width as the fin seal portion extend in the vertical direction from the upper and lower ends of the fin seal portion, respectively. 12. Guide plate 13. on the outside of the room. 13 are stacked on top of each other, and the side ends of the guide plates 12, 12 are in contact with the back surfaces of the rear walls 16, 16, as shown in the fifth figure.

Therefore, rainwater that has entered the vertical joint 2 due to the peeling of the caulking material 7 does not leak into the interior of the room, and the vertical flow passage 11.
Rainwater flows down into the lower vertical passageway 11... and rainwater that has entered the horizontal joint 3 due to the peeling of the caulking material 17 flows through the horizontal passageway without leaking to the indoor side. 18 and flows into the vertical flow passages 11...

In order to drain rainwater flowing down the vertical flow passages 11 to the outside, an appropriate drainage means is added, such as providing a drainage port at the bottom of the lowest vertical flow passage, for example.

14 is a steel reinforcing plate attached to the back side of the panel 1.

According to the vertical and horizontal joint watertight structure of the curtain wall of this invention, even if the caulking material filled in the vertical joints peels off over time and allows rainwater to infiltrate into the vertical joints, there is a The elastic packing presses the hollow seal part and the fin seal part against each other to form a double seal part and form a plurality of vertical flow passages, so that all the rainwater is drained before it reaches the room and no more water is left. Furthermore, since the guide plates of the upper and lower packings are polymerized at the intersection of vertical and horizontal joints, even if the caulking material peels off, further infiltration of rainwater can be prevented. It has excellent watertight and airtight effects, and the elastic packing has the same and symmetrical shape, and the hollow seal part, fin seal part, and seal backer material receiving part are integrally formed, making it easy and inexpensive to manufacture. It is extremely effective in practical terms, as it can significantly reduce the number of construction steps on site.
