Abstract

The seam (1) is made of a hat-shaped connector (10) and a seam cover (20), and the hat-shaped connector (10) is composed of a base plate (11) fixed to the building skeleton side, and a base plate (11) from the base plate (11). ) constitutes a convex portion (12) protruding toward the surface side. The seam cover (20) has a seam groove (21) that covers the top surface (12c) of the convex portion (12) during construction, and extends downward from its lower end to be crimped on the outer wall panel (30B) during construction. ) the lower edge portion (23) of the surface, the back side of the lower edge portion (23) is pasted with an elastic water cut-off piece (26). Thereby, it is possible to provide a seamed material having a low manufacturing cost, easy construction, and a seam portion capable of forming a design property and a high water-cutting property.

Description

technical field [0001] The present invention relates to a joint that is fixed between upper and lower adjacent outer wall panels when the outer wall panels are installed on the outer wall of a building. Background technique [0002] In order to improve the design of the building's outer wall, external wall panels such as ceramics, which have been subjected to surface pattern treatment such as natural stone style / brick tile style, are often attached to the outer wall of the building. The installation method of the outer wall panel includes the horizontal installation method of attaching the longitudinal direction of the outer wall panel to the frame side as the horizontal direction (horizontal direction), and the vertical installation method of attaching the longitudinal direction of the outer wall panel to the frame side as the longitudinal direction (vertical direction) . Usually, the upper and lower end faces of the outer wall panels adopting the longitudinal installation...

AI Technical Summary

Problems solved by technology

[0008] in such as Figure 7 In the construction structure shown, the durability of the sealing material 97 is a problem, and the sealing material 97 may be peeled off due to the infiltration of rainwater.

In addition, since the sealing material 97 is filled between the upper and lower outer wall panels 30A and 30B, a joint groove having a certain depth cannot be formed, which causes a slight problem in the design of the joint portion.

[0009] in such as Figure 8 In the construction structure shown in a, it is necessary to adjust the distance between the ends of the upper and lower outer wall panels 30A, 30B, that is, it is necessary to adjust the positions of the outer wall panels 30A, 30B to make the joint width a desired width, so the construction is very difficult. trouble

In addition, the dripping portion 53 of the middle dripping groove 50 covers the front surface of the upper end portion of the lower outer wall panel 30B, and the joint groove cannot be in a straight line in the horizontal direction, but the surface patterns of the upper and lower outer wall panels 30A, 30B are restricted Appearance of the drip part 53 separated

[0010] in such as Figure 8 In the construction structure shown in b, the shape of the middle drip channel 60 is complicated, and in order to support the weight of the upper outer wall panel 30A, the middle drip channel 60 needs to be made of an aluminum molded product, etc., resulting in an increase in cost.
