DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for waterproofing an industrialized house constructed by combining a plurality of house components.

[0002]

2. Description of the Related Art In recent years, unit construction methods have been frequently used in order to shorten the construction period of houses on site. In this unit construction method, a plurality of housing units such as a box unit, a roof unit, a terrace unit, and a balcony unit are manufactured from a housing component such as a frame and a panel at a factory or the like, and these housing units are combined on a site basis. Construction is performed by building.

[0003] In an industrialized house by the unit construction method, a waterproof portion may be formed on adjacent housing components in the same manner as a general house, but a waterproof treatment is provided between adjacent housing components of the waterproof portion. It has been subjected. For example, in an industrialized house by the unit construction method, the roof unit has a structure in which an inner wall panel is provided on the indoor side of the frame and a roof panel is provided on the outdoor side of the frame in an inclined manner. A floor panel constituting a terrace is provided below the frame because of the necessity of forming a large area, and a waterproof treatment is applied between the floor panel and the inner wall panel in a factory or the like. Also, at the site, waterproof treatment is performed between the floor panel of the roof unit and the floor panel of a terrace unit adjacent to the roof unit.

[0004] The conventional waterproofing process is performed, for example, by applying a caulking agent between housing components adjacent to a waterproofing portion between a floor panel and an inner wall panel constituting a roof unit. In addition, waterproofing of floor panels of the roof unit and the terrace unit is performed by attaching a waterproof sheet on the entire floor at the site.

[0005]

However, in a conventional waterproofing method in which a caulking agent is applied between housing components adjacent to a waterproofing portion, after the caulking agent is applied, curing is performed until the caulking agent is dried. There is a problem that it takes time. In an industrialized house in which it is desired to shorten the construction period, it takes a long time to dry the caulking agent, especially at the site.

[0006] Furthermore, waterproofing treatment with a caulking agent
There is also a problem that skill is required and waterproofing cannot always be performed sufficiently. Further, in the conventional example in which a waterproof sheet is attached to the front surface of the floor panel, since the waterproof sheet is attached to the panel using an adhesive or the like at the site, there is a problem in that it takes a long time to construct the site.

[0007] It is an object of the present invention to provide a waterproofing method for an industrialized house that can quickly and easily perform a waterproofing process on house components adjacent to a waterproofing portion.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention aims at achieving the above object by polymerizing waterproof sheets provided on each of the housing components adjacent to the waterproof portion, and welding the polymerized portions. is there. Specifically, the waterproofing method for an industrialized house according to the present invention is a waterproofing method for an industrialized house in which waterproofing is performed on a waterproof portion of an adjacent house constituent member in an industrialized house built by combining a plurality of house constituent members. A housing unit is formed from a plurality of the housing components, a waterproof sheet is attached to each of the housing components adjacent to the waterproof unit of the housing unit in the factory, and these waterproof sheets are polymerized. Parts are welded and waterproofed.
First waterproofing is applied to the housing components that make up the waterproof part of
A second sheet is attached between these first waterproof sheets.

A waterproofing method for an industrialized house in which a waterproofing part of an adjacent house constituent member is waterproofed in an industrialized house built by combining a plurality of house constituent members, wherein a waterproof sheet is provided on each of the house constituent members adjacent to the waterproof part. Then, these waterproof sheets are superposed, a superposed portion of these waterproof sheets is welded, and a covering member is attached to the housing component so as to cover the welded superposed portion.

In the present invention having such a configuration, a waterproof sheet is attached to each of the housing components adjacent to the waterproof portion in advance, and after the waterproof sheets are polymerized, the polymerized portion is heated and ultrasonically irradiated. Welding. Therefore, in the present invention, it is not necessary to use a caulking agent or the like that requires a long curing time, so that the waterproofing treatment of the housing component adjacent to the waterproofing portion can be performed quickly and easily. In particular, since the polymerized portion of the waterproof sheet is welded, the welded portion has high hermeticity, so that a sufficient waterproof effect can be obtained. Moreover, in the present invention, a housing unit is provided from a plurality of the housing constituent members, the housing unit itself is waterproofed at the factory, and the waterproofing process between adjacent housing units is performed at the site. A well-equipped factory can reliably perform waterproofing of the housing unit itself, and can quickly perform waterproofing between units on site. Moreover, in the field, the first waterproof sheet was applied directly respectively adjacent housing component and the
2 Polymerize the waterproof sheet and melt the polymerized part of these sheets.
Since it is worn, the distance between the adjacent housing components is long, and the overlapping area of the first waterproof sheet is at least at least at the site, and the second waterproof sheet covers the space between the first waterproof sheets, so that the waterproof treatment can be reliably performed. . Moreover, at the site, an intervening member such as a backup material is interposed between adjacent housing components,
Since the waterproof sheet is provided so as to cover the interposed member, even if the interval between the adjacent housing components is large, the back surface of the overlapping portion of the waterproof sheets is supported by the interposed member, so that the waterproof sheet in the waterproof portion is provided. Welding can be performed easily and reliably. In addition, by attaching a covering member to the housing component so as to cover the welded overlapped portion, the waterproof effect can be further improved.
