[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure behind a hut,
In particular, the space between the building unit and the roof panel is the back of the hut,
This hut can be used to make a fireproof space.

[0002]

2. Description of the Related Art A unit building such as a house carries a plurality of building units and roof units manufactured in advance in a factory to a construction site, where they are combined and built. In such a unit-type building, the space formed by the building unit and the roof unit is often used as the back of a hut.

[0003] By the way, in unit-type buildings that are condominiums, it is legally required that each dwelling has a fireproof structure. Therefore, the wall panels that partition each house are also made to have a fireproof structure. Here, when the back of the hut is formed in the unit-type building as described above, the boundary wall panel that partitions each hut must also have a fire-resistant structure. Japanese Patent Application Laid-Open No. 2-272123 is an example of such a back wall structure of a building unit.
According to the technology disclosed in this publication, a wall panel for eaves is mounted on an extension of the eaves side of a wall panel that partitions the back of the hut, and the back wall of the hut is partitioned by the two wall panels. It has been.

[0004]

Generally, in order to make the back of a hut partitioned by a partition wall panel a fireproof space, the upper surface of the building unit is covered with a fireproof material, and the roof panel is provided with a fireproof material. Requirements such that the gap between the upper end of the outer wall of the building unit and the back of the roof panel is closed with a refractory material. In the hut backside wall structure shown in the above-mentioned publication, the eaves backside wall panel is provided on an extension of the hut backside wall panel, and the fire between the adjacent hut backsides is provided by the two wall panels. Prevents intrusion. But,
The gap between the upper end of the outer wall of the building unit and the back of the roof panel is not closed with fireproof material, that is, the hut does not constitute a fireproof space surrounded by fireproof material. However, there is a fear that the fire may erupt from the gap to the outside and the fire may be burned to other objects, or a fire from the outside may enter the gap and cause a fire in the back of the cabin.

Therefore, it is conceivable to close the gap between the upper end of the outer wall of the building unit and the back of the roof panel with a refractory material. However, with such a structure, a normal roof panel is constructed by attaching a fire-resistant roof material to the surface of a plurality of core materials, so that a fire-resistant material that closes a gap is provided at every core material interval. It has to be formed in an uneven shape according to the material, and there is a new problem that processing is troublesome.

[0006] It is an object of the present invention to provide an easy-to-work process, to prevent fire in the back of a hut from escaping to the outside even in the event of a fire and to prevent external fire from entering the inside of the hut. It is to provide a structure.
