Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is arranged in the uppermost part of an industrialized house in which a plurality of housing units are assembled and built, and the housing units between a pitched roof and above and below This is a waterproof structure and can be used for industrialized houses built by the unit construction method.

[Background technology]

Recently, the unit construction method is being widely used in order to shorten the construction period of houses on site. In this unit construction method, modular housing units are manufactured in advance in a factory, these housing units are transported to the site by a truck or the like, and then combined on a foundation for construction.

By the way, in a house, the roof is waterproofed. In the industrialized housing by the unit construction method described above, each unit is waterproofed at the factory, but it is necessary to perform waterproofing between the units at the site.

In some of the roofs of this house, a house unit having a pitched roof and a house unit for pitched roof are arranged below the water (eave side) of the house unit. The waterproofing of this type of roof is performed by applying caulking material to the joints between the units or by attaching a waterproof sheet to both units.

[Problems to be Solved by the Invention]

However, in the conventional example in which caulking material is applied between units or a waterproof sheet is attached to each unit, since waterproofing is performed by a so-called wet treatment, a long curing time is required until the caulking material or the like is dried. There is a problem. In addition, the method of using caulking material has a problem that no one can easily carry out waterproofing because skill is required.

An object of the present invention is to provide a waterproof structure for an industrialized house, which can quickly and easily carry out waterproofing between a housing unit having a roof and a roof housing unit.

[Means for solving the problem]

A waterproof structure for an industrialized house according to the present invention forms a step at a joint portion of units which are adjacent to each other in a roof inclination direction among housing units constituting a roof, and a flexible waterproof member is interposed between the steps. This simplifies waterproofing.

A specific configuration of the present invention is a waterproof structure between a housing unit having a pitched roof of an industrialized house in which a plurality of housing units are assembled and built, and a housing unit for pitched roofs arranged under water of the housing unit. A flexible waterproof member is interposed between the lower surface of the eaves end of the housing unit having a pitched roof and the upper water side upper surface of the housing unit for a pitched roof.

Here, as the waterproof member, butyl-impregnated urethane foam, ethylene / propylene / polypolymer (EPDM)
Water-tight materials such as

[Action]

In the present invention having such a configuration, the first-floor housing unit,
After assembling a plurality of housing units such as a second-floor housing unit by hanging them with a crane on site, a pitched roof housing unit is placed on the top floor of these units. Here, a waterproof member is previously attached to the upper water side upper surface of the house unit for pitched roof at a factory or the like.

After that, a housing unit having a pitched roof next to the pitched roof housing unit is hung with a crane and lowered.
As a result, the waterproof member is compressed between the upper water side upper surface of the pitched roof housing unit and the eaves tip lower surface of the housing unit having the pitched roof, and the waterproofing process is completed. In this state, even if the surface of the water upper end of the pitched roof housing unit and / or the water lower end (roof eaves) of the housing unit having a pitched roof is slightly distorted due to processing error, assembly error, etc., this distortion is absorbed. As described above, the waterproof member is deformed to close the gap between both units, and rainwater does not enter between the units.
