[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a hut set above a top floor of a building and a reinforcing metal used in the method of structuring the hut.

[0002]

2. Description of the Related Art Hitherto, when building a hut of a building such as a house, members such as beams, bundles, purlins, purlins, and rafters have been assembled at high places. However, since the work position is at a high place, workability is poor, and the construction takes time and effort.

[0003] Therefore, a method of reducing the work at high places by assembling the hut assembly in advance on the ground and then mounting the hut assembly on a roof portion by lifting it with a crane or the like is considered.

[0004]

However, in an urban area or the like, in order to effectively use land, a building that uses almost the entire site is often constructed. Therefore, it is difficult to secure the room for assembling the hut assembly on the ground outside the building to be constructed in the site as described above. Alternatively, a method of assembling a hut in advance at a location outside the site and transporting it to a building construction site is also conceivable. However, since the assembled hut has a plane dimension almost equal to or larger than the plane of the building, it is difficult to transport the building to a building construction site using a narrow road in an urban area.

[0005] An object of the present invention is to assemble a hut assembly mainly inside the outer wall line of a building when constructing the building on a site in an area where the buildings are densely packed, and greatly reduce dangerous work at high places. It is an object of the present invention to provide a method of constructing a hut group, which can reduce the labor and time required for construction with a minimum.
