As shown in the figure, a large number of ventilation holes 221 communicating with the back of the hut similar to the above embodiment are formed.
A fire damper (not shown) that closes in the event of a fire is attached. The arrow indicated by the symbol K is a ventilation path.

The roof units Y11 to Y14 of this embodiment
At the time of on-site construction, in which the unit is installed above the room unit A and connected, the so-called eaves-free operation is performed, so that even a small site can be handled. In addition, since the roofing material 1 is attached at a building site by retrofitting and forms an eaves part protruding to the outside from the wall of the room unit, the eaves part has a good raining behavior.

[0026]

According to the roof unit of the present invention, the head joint joined to the wall of the room unit is attached directly below the fascia, so that the eaves are formed in the room like the conventional roof unit. It can be used on a small site without protruding from the unit. In addition, the conventional roof unit has to be transported upright because the eaves protrude, so the plane area is larger than the room unit, but the roof unit of the present invention can be transported while lying down. The turning work at the installation stage is unnecessary, which is convenient.

According to a second aspect of the present invention, in the roof unit according to the first aspect, a ventilation hole is formed in the fascia, so that the back of the cabin can be ventilated through the ventilation hole. Furthermore, this through hole can be used as a joining space when joining the head tie and the wall of the lower room unit.

The third aspect of the present invention is the first or second aspect.
In the described roof unit, a roofing material is attached to the roof unit at the construction site, and the eaves protruding to the outside from the wall of the room unit is formed. .
