Embodiments of the present invention will be specifically described below with reference to the drawings. Basically, the assembly structure of the assembled house unit according to the present invention has a structure in which the ceiling surface 3 and the bottom surface 4 of each of the assembled house units 1 and 2 are provided with a downward projecting piece 5 facing the bottom surface and the ceiling surface of the other side. An upper projecting piece 6 is provided, and these are connected in a horizontal direction with a connecting fixture 7 such as a bolt and a nut, in this embodiment, a bolt 7A and a nut 7B.

The projecting pieces 5 and 6 have a cylindrical, L-shaped or U-shaped cross-sectional shape having joint side surfaces facing each other in at least two directions, and are connected by the connecting fixture 7 on each joint side surface. There is. In particular, in this embodiment, the projecting pieces 5 and 6 have the joining side surfaces 5 facing each other in the four directions.
It has a rectangular tubular shape having A to 5D and 6A to 6D and is sized to fit with each other.

The projecting pieces 5 and 6 are equipped with mounting base plates 5E and 6E located on the ceiling surface of the assembled house unit 1 and the bottom surface of the assembled house unit 2 and welded to the frame of each unit. Further, the cut portions 5F and 6F are formed at the respective corner portions of the rectangular tube so that the joint side surfaces form independent plate-shaped portions.

Further, in this embodiment, in order to facilitate the fitting of the projecting pieces to each other, the upper edges of the independent joint side surfaces 5A to 5D are bent inward. Further, the protruding piece 6 is located at the center thereof, and the upper assembled house unit 2 is temporarily received by the lower assembled house unit 1,
Further, in order to determine the height of the protruding pieces, a column piece 8 having a predetermined length is attached downward.

The projecting pieces 5 and 6 are provided with mounting holes 9 and 10 which are located on the respective joint side surfaces and through which the bolts 7A of the connecting fixture 7 are inserted. Has been formed. The nut 7 </ b> B of the connecting fixture 7 is welded to the protruding piece 5 on the back side of each joint side surface (inside the protruding piece 5) at a position corresponding to the mounting hole 9.

With such a construction, when the upper assembly house unit 2 is suspended by a construction machine such as a crane and placed on the ceiling surface of the lower assembly house unit 1, the projecting piece 6 is replaced by the projecting piece 5.
And the pillar pieces 8 are abutted against the ceiling surface, whereby the upper assembly house unit 1 is temporarily received, and the upper and lower positions of the protruding pieces are determined, and in that state, the mounting holes 9 and 10 are set. The bolt 7A is screwed into the nut 7B via the screw.

In this case, since the joint side surfaces are independent by the notches 5F and 6F, they can be bent by tightening the connecting fixture 7, and the protrusions formed for fitting in advance. The mutual clearance can be eliminated. With this clearance left,
In FIG. 3, it is shown by the connecting portion on the left side of the joint of the protruding piece.

Further, in this embodiment, the respective coupling structures are arranged / configured in at least four corners of the assembled house unit. Therefore, since the mounting base plates 5E and 6E are directly connected and fixed to the columns 11 and 12, sufficient strength can be secured.

In this embodiment, the projecting piece has a cylindrical shape, but as described above, it is of course possible to employ an L-shaped cross section or a U-shaped cross section. . Further, it is preferable to form a plurality of engaging side surfaces that are coupled by the connecting fixture 7 in at least two directions, for example, the front-rear direction and the left-right direction of the assembled house unit. When the lower projecting piece 5 and the upper projecting piece 6 are formed in a cylindrical shape that can be inserted into each other, the tip portion of the inner projecting piece is tapered or the tip portion of the outer projecting piece is tapered. By making the diameters, they are guided to each other to facilitate the insertion and connection work.
