[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for a house frame structure which can easily connect two house frame structures which are independently constructed.

[0002]

2. Description of the Related Art In recent years,
For example, as schematically shown in FIG. 13, a plurality of pillars a ...
A building e such as an apartment house which is constructed as a single building by connecting two house frame structures c and d having beam members b ...

However, as shown in the same figure, such a building e has heretofore been a pillar a1 ..., Of each house frame structure c, d.
Since the house frame structures c and d are integrally built by sharing the beam members b1 ..., the structure of the house frame structures c and d is greatly affected, and it is difficult to construct each house independently. The degree of freedom of building the frame structures c and d is reduced, and the building positions of the house frame structures c and d are the pillars a1 ...
There is a problem to be solved such as being largely restricted by the sharing of the beam members b1, ... As a result, the building e is largely restricted in its designing stage.

The present invention is based on the fact that the wall frame structures of the two house frame structures are arranged in parallel and at intervals, and the two house frame structures are connected by a connecting metal fitting that extends over the interval. The purpose of the present invention is to provide a connection structure of house frames that can increase the degree of freedom by independently constructing the frames.

[0005]

In order to achieve the above-mentioned object, a connecting structure for a house frame structure of the present invention comprises a plurality of pillars standing on a straight line at a constant pitch and a horizontal beam connecting the pillars. Two house frame structures including a wall frame structure made of wood are arranged in parallel with the wall frame structures in parallel and at intervals and columns are displaced, and one of the house frame columns and the other The beam member of the house frame structure is connected to the pillar at one end, and the other end is bolted to a mounting piece that is provided on the beam member and is parallel and perpendicular to the beam member. Are connected.

[0006]

[Operation] Two house frame structures having a wall frame structure composed of a plurality of pillars standing upright in a straight line and beam members connecting the pillars,
The wall frame structures are arranged in parallel and at intervals. Therefore,
It is possible to construct the two house frame structures independently of each other, and it is possible to increase the degree of freedom in building each house frame structure. Moreover, since the two house frame structures are independently configured, it is possible to appropriately change the relative position in the horizontal direction at the design stage.

Further, since the pillar of one house frame structure and the beam member of the other house frame structure are connected with each other by using the connecting metal fittings that straddle the above-mentioned gap using the bolts, one building structure from two house frame structures. Can be easily formed without impairing the workability.
