BACKGROUND ART In recent years, a unit-type building constructed by combining a plurality of building units manufactured in a factory in advance at a construction site has been widely used as a building to be used for a house or the like. The building unit is equipped with steel frames for pillars and beams, and has floor materials, wall materials, ceiling materials, etc. pre-installed at the factory.After being transported to the construction site, it is combined and combined with other building units. Be done. As described above, in the unit type building, since most of the construction work of the floor material, the wall material, the ceiling material and the like is performed in the factory, the work at the construction site can be reduced, so that the construction period can be shortened.

In the unit type building as described above, a continuous living room space may be formed over a plurality of building units. In this case, in the factory, floor materials, wall materials, ceiling materials, etc. are used between the building units.

At the construction site, after combining building units, the floor between the building units,
A wall, a ceiling or the like is covered with a connecting face material or the like and finished (conventional example: JP-A-8-21024).

[0004]

In the above-mentioned conventional example, the connecting face member is set to have a width dimension that covers a space between a pair of adjacent beams, and must be directly screwed and fixed to the steel beam forming the frame. Therefore, the work at the construction site is complicated and time-consuming. In addition, since the connecting face material is set to have a width dimension corresponding to the space between the pair of beams, the connecting face material has a narrow width dimension, which makes it difficult to process or handle.

It is an object of the present invention to provide a connecting structure for a planar structure which facilitates the processing and handling of the connecting face material and improves workability at a construction site.

[0006]

Therefore, the connecting structure of the planar structure according to the present invention as set forth in claim 1 will be described with reference to the drawings. The planar structures 20 having the face material main body 15 to be attached are made to face each other so that their substantially linear connection side edges face each other so as to be on substantially the same plane, and are connected across the planar structures. In the connection structure of the planar structures which are connected by attaching the face plate 30, the frame member is arranged at least along the connection side edge, and the frame member is inwardly spaced at a predetermined distance from the frame member. A base material 17 for attaching the connecting face material is provided substantially in parallel with the connecting side edge, and the connecting side edge of the face material main body is located on the base material or inside the base material. And

In the present invention having the above construction, the base material is provided at a position distant from the frame material, and the planar structures are connected by attaching the connecting face material to the base material. Therefore, the width dimension of the connecting face material is not restricted by the dimension between the pair of adjacent frame members, and the width can be set to an appropriate width, so that the connecting face material can be easily processed and the handleability is improved. Will be possible. Moreover, since the connecting face material is attached to the base material, it is not necessary to directly fix the connecting face material to a steel beam or the like with screws. Therefore, the connecting face material can be easily attached, and the workability at the construction site can be improved.

It is characterized by being an auxiliary joist that is erected between 16. In this way, since the base material is erected by using the adjacent joists, the base material can be easily created and does not require much labor. Further, the planar structure can be made stronger by connecting the base material with the joists that are laid only in one direction.

According to a fourth aspect of the present invention, there is provided a planar structure connecting structure according to any one of the first to third aspects, wherein the base material 17 has the surface structure. It is characterized in that the edge of the material body 15 is fixedly joined. By doing so, it is economical because it is not necessary to separately provide a member for attaching the face material main body, and the attachment of the face material main body can be made more reliable as compared with the case where it is fixed only to the joists.

According to a fifth aspect of the present invention, there is provided a planar structure connecting structure according to any one of the first to fourth aspects, wherein the planar structure 20 is It is characterized as being configured as a part of a building unit 1 having a steel frame 10 configured by combining a pillar 11 and beams 12, 13 in a substantially rectangular parallelepiped shape. In this way, when a planar structure is used as a part of the construction of building units, the steel frames of columns and beams are exposed at the connecting parts due to the combination of building units. Therefore, it becomes possible to connect the continuous planar structures across the building units.
