Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is arranged in the uppermost part of an industrialized house constructed by assembling a plurality of housing units, and is provided between housing units with pitched roofs adjacent to above and below water. Regarding waterproof structure,
It can be used for industrialized housing built using the unit construction method.

[Background technology]

Recently, unit construction methods have been increasingly used to shorten the construction period for housing on site. This unit construction method involves manufacturing modular housing units in advance at a factory, transporting these housing units to the site by truck, etc., and then assembling them on a foundation for construction.

By the way, in houses, waterproofing treatment is applied to the roof. In manufactured housing using the unit construction method described above, each unit is waterproofed at the factory, but waterproofing between units must be done on site.

The roof of this house includes a housing unit with a sloped roof and a housing unit with a sloped roof arranged below the water (on the side of the eaves) of this housing unit. This type of roof is waterproofed by applying caulk to the joints between the units, or by attaching waterproof sheets to both units.

[Problem to be solved by the invention]

However, in conventional methods of applying caulking between units or attaching waterproof sheets to each unit, waterproofing is done through a so-called wet process, which requires a long curing time for the caulking to dry. There is a problem. Additionally, the method of using caulking requires skill, so there is a problem in that not just anyone can perform waterproofing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a waterproof structure for an industrialized house that can quickly and easily perform waterproofing between a housing unit having a roof and a housing unit for the roof.
