DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry joint gasket mounting method and a dry joint gasket for joint treatment of a building outer wall using a dry joint gasket.

[0002]

2. Description of the Related Art When constructing a building such as a house,
At the factory, panel construction methods are being introduced to increase the degree of component completion as much as possible and reduce the number of work items at construction sites. For example, an outer wall of a building by a panel construction method is formed by arranging a plurality of wall panels at predetermined positions. The outer wall thus formed needs to be waterproofed at the joint between the adjacent outer wall panels.

As a waterproofing treatment for joints, there is a method of filling a joint with a caulking material on site. In this method, first, a backup material formed of urethane foam rubber or the like is press-fitted into the joint from a surface side of the joint to a predetermined position, then a caulking material is filled from the surface side of the joint, and finally, the front side of the caulking material is shaped with a spatula or the like. Is what you do. The backup material has a cross section wider than the width dimension of the joint, and is compressed and deformed by being press-fitted into the joint to perform self-holding. The backup material elastically holds the adjacent wall panel, absorbs the impact at the fore-edge surface, secures the two-sided adhesion of the caulking material, and prevents the caulking material from flowing out to the joint back side.

[0004] As described above, the technique of filling a joint with a caulking material and performing the joint treatment requires many operations such as press-fitting a backup material, filling a caulking material, and shaping a caulking material. High construction efficiency could not be obtained. In particular, in the press-fitting work of the backup material, if the backup material is pushed too far in the thickness direction of the outer wall panel, the backup material may fall off from the back of the joint, and skill is required.

In addition to the method of filling the joint with a caulking material, there is a technique of inserting a dry joint gasket formed of a synthetic resin or the like into the joint in order to perform joint processing more easily. The dry joint gasket has an engaging portion having a width dimension larger than the joint width, and the joint is filled by pressing the engaging portion into the joint. As described above, since the dry joint gasket can be subjected to waterproof treatment at the joint only by being inserted into the joint, workability can be improved without requiring skill.

In the conventional joint treatment, even when a caulking material is used or a dry joint gasket is used, since the work is performed from the front side of the wall panel, at least a worker can work on the front side of the outer wall. Work space needed to be secured. However, in recent years, with the density of buildings particularly in urban areas, there has been a problem that the space between buildings is narrow, and it is difficult to secure a work space on the front side. Further, in order to perform the joint processing work on the upper floor of the building, a larger space is required for installing a work scaffold on the outer side of the outer wall or arranging a movable work scaffold.
