Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous unit building in which a plurality of unit buildings are connected through a joint member.

[0002]

2. Description of the Related Art Conventionally, a living room or the like constituting a building in a factory is manufactured as a building unit, these building units are transported to a site, and a plurality of building units are combined in a horizontal and vertical direction to construct a building. A unit building is being constructed. The joint between the outer wall materials of the building units adjacent to each other in the horizontal and vertical directions is filled with a caulking material as a joint material and a backup material for caulking.

When building a unit-type building on site, a caulking backup material is usually provided for joints in the vertical direction between outer wall members of horizontally adjacent building units. Filling caulk with gun. On the other hand, as shown in FIG.
An expansion joint of one unit building 12A, 12B to obtain a housing complex using 11A, 11B
A plurality of units, for example, a unitary building 14 that is a series of two connected units is proposed via 13.

[0004]

In the case of constructing a unit type building for one building, the caulking material filling operation can be easily performed from the outside even for the joints in the vertical direction. On the other hand, in the case of the unit building 14 of the above-mentioned multi-story building, at the time when only one unit building 12A of the unit buildings 12A and 12B to be opposed is installed, the other building unit 12B does not exist. Therefore, the caulking material can be filled from the outside to the joint 21 in the vertical direction between the outer wall panels 15 which are the outer wall materials of the adjacent building units 11A and 11B of the one unit building 12A.

However, after the other unit type building 12B facing the one unit type building 12A is also installed, the vertical direction between the outer wall panels 15 of the adjacent building units 11A, 11B of the other unit type building 12B. The task of filling caulking material into the joint 21 is a problem. That is, it is very difficult or impossible to perform the caulking material filling work in the joints 21 in the vertical direction from the outdoor side, because the one unit building 12A is an obstacle.

In view of the above, the present invention provides a continuous unit building in which caulking material can be provided without any trouble at joints between a plurality of outer wall members forming opposite outer wall surfaces of unit buildings adjacent to each other. The purpose is to provide the construction method.
