Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

First, the basic structure of the wall-type building unit constituting the wall-type building will be described with reference to FIG. 3. Reference numeral 1 is a floor panel, and the wall panels 2 and 3 are attached to each side of the floor panel 1. The wall-type building unit 4 is assembled. The floor panel 1 and the wall panels 2 and 3 are made to have strength as a bearing wall by sticking a face material 7 such as a hard wood chip cement board or plywood to a frame body 6 made of a frame material 5 by nailing or the like. It is configured. The wall panels 2 and 3 form a girder wall and a gable wall of the building unit 4, and the gable wall wall panel 3 is arranged so as to be orthogonal to the end portion of the girder wall wall panel 2.

Then, in order to join the adjacent wall panels 2 and 3 to each other at their upper end portions, a metal joining member 8 formed in a glazing shape as shown in FIG. 2 is used. It is arranged so as not to interfere with a joint plate 9 described later and is provided so as to straddle the upper ends of the wall panels 2 and 3. Specifically, the joining member 8 is formed by bending a metal rod into a U shape and sharpening both ends. As shown in FIG. 1, a pair of joint members 8 are provided on both sides of the joint plate 9 so as to straddle the upper ends (upper frame members) of the frame bodies 6 of the adjacent wall panel 2 for girder wall and the wall panel 3 for gable wall. Joining plate 9 to be positioned
It is struck and fixed in parallel with the girder wall at an interval of at least the width of. As shown in FIG. 4, the joining member 8 not only joins the girder wall 2 and the gable wall 3, but also joins the girder wall 2 and the gable wall 12,
It is also applicable to joining the partitions 13 and the like.

The building unit 4 is assembled in the factory with the above-described joint structure of the wall panels 2 and 3, and then joined appropriately in the horizontal direction and the vertical direction on the foundation of the construction site so that a predetermined building is formed.
