Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall structure in a building such as a house of a panel construction method.

[0002]

2. Description of the Related Art Conventionally, as the exterior design of a two-story house, the color pattern of the outer walls of the first and second floors is changed, and the joint is raised above the floor level of the second floor so that the color pattern of the outer wall of the first floor is at a high position. Some have been extended to. Such an appearance is called a waist-high design, and is preferred as an appearance with a sense of weight. There are the following two methods for adopting the exterior design in a panel construction house. One is a method of attaching the exterior surface material on site after building the outer wall panel without the exterior surface material for finishing. The other one is to build the outer wall panel on the 2nd floor with the exterior surface material on the lower side not attached, and then attach the exterior surface material on the spot between the outer wall panel on the 1st floor and the upper and lower horizontal joints. It is a method of sealing.

[0003]

However, the above-mentioned method of sticking all the exterior facing materials on site has the problems that it takes time and labor for the on-site construction and the construction period becomes long. In addition, the above-mentioned method of pasting the part to be pasted on-site is performed by sealing the upper and lower horizontal joints of the on-site pasted part, so that the horizontal joint at the lower end of the on-site pasted part is the sealing on the colored pattern part of the outer wall on the first floor Therefore, there is a problem in that the appearance of a waist-high design that is full of weight is damaged.

An object of the present invention is to easily realize an outer wall having an outer appearance in which the color pattern of the outer wall of the lower floor is extended to a high position in a panel construction method, and in which the horizontal joint is not conspicuous in the portion of the same color pattern, and the waterproof property is obtained. Is also to provide an excellent outer wall structure.

[0005]

The present invention is applied to an outer wall in which the color pattern of the exterior surface material is different for the upper floor outer wall panel and the lower floor outer wall panel which are vertically arranged. Both exterior surface materials may be different only in color or pattern, or may be different in both color and pattern. The pattern as used herein includes a three-dimensional pattern, and the color pattern also includes a material feeling. At the lower part of the outer wall panel of the upper floor and the upper end of the outer wall panel of the lower floor, a sticking-back portion in which the exterior surface material is sticked out and the base material is exposed is provided. Further, a field-applied exterior surface material having the same color pattern as the exterior surface material of the first-floor outer wall panel and having upper and lower end portions respectively covering the pasting prevention portions of the outer wall panels on the upper and lower floors is provided. A waterproof tape is interposed between the lower surface of the bottom surface of the exterior surface material to be stuck on site and the base material of the sticking part. The lower end of the exterior surface material attached on site and the upper end of the exterior surface material of the lower floor outer wall panel are intermeshed with each other by the concave portion and the ridge along the lateral width direction, and the waterproof material is interposed on the engagement surface.

[0006]

According to this outer wall structure, the exterior surface material applied on site and the exterior surface material of the outer wall panel of the lower floor are joined by the engagement of the recess and the ridge along the lateral width direction, and no wet seal is provided. Therefore, the horizontal joint is not noticeable. For this reason, a so-called waist-high appearance design in which the exterior surface material of the lower floor outer wall panel continuously extends to the site-applied exterior surface material can be favorably obtained. In addition, at the joint portion at the lower end of the exterior surface material to be pasted on site, a sealing material is provided at the engaging portion and a waterproof tape is provided between the exterior surface material and the base material, so double waterproofing is achieved. The structure makes it possible to carry out reliable rain-fighting.
