Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for constructing a hut set installed above the top floor of a building.
[0002]
[Background technology]
In the past, when building a hut of a building such as a house, members such as beams, bundles, purlins, purlins, rafters were assembled at high places. However, since the work position is high, workability is poor, and the construction takes time and effort.
[0003]
Therefore, a method of reducing work at a high place is conceivable by pre-assembling the roof set on the ground and then lifting it with a crane or the like and attaching it to the roof portion.
[0004]
[Problems to be solved by the invention]
However, in urban areas and the like, in order to use land effectively, there are many cases where a building that uses almost the entire surface of the site is constructed. Therefore, it is difficult to secure room for assembling the hut assembly on the ground outside the building to be constructed on the site.
In addition, a method of transporting to a building construction site after pre-assembling a cabin set in a place outside the site is also conceivable. However, since the assembled hut has a plane dimension approximately equal to or exceeding the plane of the building, it is difficult to transport it to the building construction site using a narrow road in an urban area.
[0005]
The problem of the present invention is that when building a building in an area where the buildings are densely packed, the assembly work of the hut is performed exclusively inside the outer wall line of the building, and dangerous high place work is greatly reduced. The purpose is to provide a method for constructing a hut that can reduce the labor and time required for construction.
[0006]
