BACKGROUND OF THE INVENTION
The present invention relates to a method for mounting a dry joint gasket for performing joint treatment on an outer wall of a building with a dry joint gasket .
[0002]
[Prior art]
When building a building such as a house, panel construction methods are being introduced to increase the completeness of parts as much as possible at the factory and reduce the number of work items at the construction site. For example, the outer wall of a building by the panel method is formed by arranging a plurality of wall panels at predetermined positions. And the outer wall formed in this way needs to waterproof the joint between each adjacent outer wall panel.
[0003]
As a waterproof treatment for joints, there is a method in which caulking material is filled in the joints at the site. In this method, first, a backup material made of foamed urethane rubber or the like is pressed into the joint from the joint surface side to a predetermined position, then the caulking material is filled from the joint surface side, and finally the front side of the caulking material is shaped with a spatula or the like. To 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 holds the adjacent wall panel with elasticity, absorbs the impact on the facet, and secures the two surfaces of the caulking material, and prevents the caulking material from flowing out to the joint back side.
[0004]
The technology for filling joints with caulking material as described above requires many operations such as press-fitting of backup material, filling of caulking material, and shaping of caulking material, and high construction efficiency. I could not get sex. In particular, for the press-in operation of the backup material, if the backup material is pushed too far in the thickness direction of the outer wall panel, it may fall off from the joint joint, and skill is required.
[0005]
In addition to the method of filling the joint with the caulking material, there is a technique of inserting a dry joint gasket, which is formed in advance of a synthetic resin or the like, into the joint in order to perform the joint treatment more easily. The dry joint gasket has an engaging portion whose width is larger than the joint width, and the joint is filled by press-fitting the engaging portion into the joint. Thus, since the dry joint gasket can be waterproofed at the joint simply by being inserted into the joint, the workability can be improved without requiring skill.
[0006]
In conventional joint processing, work is performed from the front side of the wall panel even when caulking material is used or when a dry joint gasket is used. It was necessary to secure. However, with the recent increase in the density of buildings, particularly in urban areas, there is a problem that the location interval between buildings is narrow and it is difficult to secure a work space on the front side. Further, in order to perform joint processing work on the upper floor of the building, a larger space is required for constructing a work scaffold on the front side of the outer wall or arranging a movable work scaffold.
[0007]
[Problems to be solved by the invention]
In order to solve the above problem, a joint structure as shown in FIG. 9 is proposed in JP-A-5-31770. The joint structure shown in FIG. 9 includes a joiner A, a panel B, a base material α, and a fixture β. The joiner A installs the installation piece 101 on the columnar base material α, and extends downward from the installation piece 101 at a right angle. The fixing pieces 102 and 103 formed by bending to the base material α are fixed to the base material α by the fixing tool β, and are arranged on the base material α.
[0008]
Further, the joiner A is formed with a rising piece 104 in which the central portion of the installation piece rises at a right angle upward, and the rising piece 104 is provided with a packing body 105 having elasticity. In this way, the panel B is suspended from the base material α to which the joiner A is attached by using a gondola, a crane, a winch or the like, and the panel B is fixed so that the end face B1 thereof is in close contact with the packing body 105 to form a joint portion. To do.
[0009]
According to the above prior art, the panel B is arranged on the packing body 105 formed in advance to form the outer wall, so that waterproofing at the joints can be performed without working from the outside of the building for joint treatment. Can be secured. However, when the panel B is erected, there is a problem that it is necessary to arrange the panel B accurately so that the panel B comes into close contact with the packing body 105, and it takes time to install the panel. In addition, since it is necessary to attach the joiner A to the base material α with the fixture β, there is a problem that the installation work is troublesome.
[0010]
In addition to the above-described conventional technique, in Japanese Patent Application Laid-Open No. 5-133067, as shown in FIG. 10, a covering portion 111 that covers the joint, an insertion portion 112 that is connected to the covering portion 111 and is inserted into the joint, The joint processing material 130 which has the engaging part 113 formed in the part 112 and press-fitted in the joint, and can be installed from the indoor side of the building is presented. The joint treatment material 130 is configured such that the insertion portion 112 is inserted into the joint, is pulled in from the joint back side, the engagement portion 113 is press-fitted into the joint, and is fixed on the inner wall side by a retaining member.
[0011]
However, in the above prior art, when the joint treatment material 130 is disposed on the joint, the joint treatment material 130 is first suspended from above the outer wall, the covering portion 111 and the engagement portion 113 are disposed on the front side of the joint, and then inserted. Since the portion 112 is inserted into the joint and pulled in from the inside, there is a problem that it is necessary to raise the joint treatment material to a position higher than the outer wall, which takes time. Further, after the joint treatment material 130 is disposed, the insertion portion 112 protrudes from the joint, and there is a problem in appearance because the insertion portion 112 is fixed with a retaining member. Or when the insertion part 112 is cut | disconnected, since it was set as the structure filled with a caulking material from the inner side, there existed a problem that a man-hour increased and work could not be performed efficiently.
[0012]
