Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an inner gutter type roof unit, and can be used for roofs of unit houses, etc.

[Background technology]

Traditionally, rain gutters have been installed on the roofs of houses to collect and drain rainwater. Rain gutters installed in ordinary houses are called outer fences, which are attached along the edge of the eaves of the roof.

On the other hand, in consideration of appearance, etc., a structure called an inner gutter, in which a rain gutter is installed inside the end of the roof, is also adopted.

Incidentally, a unit house is constructed by assembling living room units, roof units, etc. that are prefabricated in a factory at a construction site. In such unit houses, because it is necessary to arrange the rain gutters so that they go around almost the entire roof, outer fences that are installed after each unit is assembled have been used exclusively.

[Problem to be solved by the invention]

By the way, in the above-mentioned outer fence, since the eave side edge of the roof is located at a high position, 1. Installation work is troublesome. especially,
Scaffolding, which is basically unnecessary in unit housing, is required, and there is a problem in that on-site work becomes complicated, such as the need for protection for walking on the roof during work.

An object of the present invention is to provide an inner gutter type roof unit that can facilitate work at a construction site.

[Means to solve the problem]

The present invention provides a plurality of internal gutters arranged along the edge of the eaves on the roof of a unit house, and allows the ends of the internal gutters of adjacent roof units to be connected to each other.

[For production]

According to the present invention, a roof unit in which inner gutters are pre-assembled is assembled at a construction site, and the rain gutters are formed by connecting the inner gutters to each other. Therefore, most of the installation of the rain gutter can be done in advance at the factory, eliminating the need for on-site installation work. In particular, since connecting the inner gutters of roof units is a partial task, it can be easily done using a stepladder, etc., and there is no need for large-scale scaffolding around the unit housing or preparatory work such as protecting the roof. , these achieve the above objective.
