Description

Detailed Description of the Invention 【Technical field】

The present invention relates to a joint structure of an outer wall, and more particularly to a joint structure of an outer wall of a steel-framed house.

[Background technology]

As shown in FIG. 2, even in a steel-framed house having a steel-framed column 6 in which a panel is used as the outer wall material 7, joint treatment has conventionally been performed by wet caulking with a mortar 8 or the like. In addition to having problems in terms of quality stabilization, the outer wall is often soiled, and the time required for joint treatment is inevitably long.

[Object of the Invention]

The present invention has been made in view of the above points, and an object of the present invention is to provide a joint structure of an outer wall that can obtain joint treatment of stable quality under good workability. .

DISCLOSURE OF THE INVENTION

Thus, the present invention provides an inorganic plate on the surface of a steel column through a heat insulating material, and a pair of adjacent exterior materials is provided on the front surface side of the inorganic plate, and the back surface side of the exterior material and the inorganic plate. And a caulking material between them to form a gap between the end faces of the two exterior materials facing each other, and the joint subsurface watertight material and the joint cover held by the joint subsurface watertight material are provided in the gap. The feature is that they are arranged. The present invention will be described in detail below with reference to the illustrated embodiments.
As shown in the figure, an inorganic plate 3 such as a calcium silicate plate is attached to the surface of the steel column 6 via a heat insulating material 2 made of foam. This attachment is performed by an adhesive provided on both sides of the heat insulating material 2. When arranging the exterior material 1 composed of the plywood 11 and the inorganic board 12 so that the joint is located at the portion of the steel column 6, the caulking material 9 is provided between the back surface of the inorganic board 12 and the inorganic board 3. And a space is provided between the side end surfaces of the exterior material 1, and a water-sealing material 4 for the underground soil and a joint cover 5 made of a synthetic resin are arranged in the space. To do. The joint cover 5, which has a T-shaped cross section and has a serration-like retainer on a piece to be inserted into the subterranean watertight material 4, is held by the subterranean watertight material 4, and the edges of both side pieces are The side end surface of the exterior material 1 is elastically contacted. Although the caulking material 9 is used together, the caulking material 9 is for secondary waterproofing to be filled between the back surface of the exterior material 1 and the inorganic plate 3, and the gap portion between the exterior materials 1 and 1 is The joint treatment is performed by a dry treatment using the water-sealing material 4 for the joint ground and the joint cover 5, and since only the joint cover 5 is exposed to the outside, the filling work of the caulking material 9 is concerned with the appearance. It can be carried out quickly without any action, and the presence of the inorganic plate 3 contributes to ensuring fire resistance.

【The invention's effect】

As described above, in the present invention, although the caulking material is used, the caulking material is filled between the back surface of the exterior material and the inorganic plate for ensuring the fire resistance provided on the surface of the steel column through the heat insulating material. It is for secondary waterproofing, and the gap between the facing end faces of the exterior material is treated by dry treatment with the water-sealing material for the underground soil and the joint cover, so the caulking material is not exposed to the outside. Therefore, when filling caulking material, it can be installed quickly without paying attention to its appearance. The workability is good, and since only the joint cover is exposed to the outside, the quality is stabilized and the outer wall is not contaminated during the work.

Claims (1)

[Claims] 1. An inorganic plate is arranged on the surface of a steel column via a heat insulating material, and a pair of adjoining exterior materials is arranged on the surface side of the inorganic plate, and the back side of the exterior material and the inorganic plate are provided. A caulking material is filled in between the outer casings to form a gap between the opposite end faces of the two exterior materials, and the joint underground watertight material and the joint cover held by the joint underground watertight material are arranged in this gap. The joint structure of the outer wall is characterized by being installed.
