BACKGROUND ART In recent years, a unit construction method that is capable of reducing the on-site work and shortening the on-site construction period is being widely used. In this unit construction method, a box-type housing unit is usually stacked to build a building, and each housing unit is manufactured with an appropriate steel material and structure so as to obtain sufficient rigidity and proof stress. Then, each of these housing units is stacked on site, the units installed in the vertical direction are connected by bolts, and the units installed in the horizontal direction are positioned and connected via a plate that is horizontally arranged. It was

[0003]

However, the joints between the housing units, particularly the horizontal joints which are joined through the plates, are mainly used for positioning the housing units and do not transmit force. Therefore, for example, four pillars of each housing unit will be gathered at the corner where four housing units are gathered. However, each pillar is structurally independent, and the rigidity and the yield strength are large for the large amount of steel used. There was a problem that was small. In other words, even if you are using a housing unit that has sufficient rigidity and proof strength by itself,
In the unit housing that combines these, there is a problem that rigidity and proof stress are small compared to the usage amount of the steel material.

An object of the present invention is to provide a unit housing consisting of a plurality of housing units with a rigidity with respect to the amount of steel used,
It is to provide a joint reinforcement structure for a housing unit that can improve the yield strength.

[0005]

SUMMARY OF THE INVENTION The present invention is a joint reinforcing structure for housing units constituting a unit house,
The columns of the adjacent housing units are fixed to each other via a joint piece that is long in the column direction. At this time, the pillars of the horizontally adjacent housing units may be fixed to each other via the joint pieces, or the pillars of the vertically adjacent housing units may be fixed to each other. Also,
You may arrange | position in the joint part of a housing unit of a horizontal direction and an up-down direction, and fix the pillars of both directions via one joint piece.

[0006]

In the present invention as described above, since the columns of the adjacent housing units are fixed to each other by using the joint piece which is long in the column direction, the joint strength is improved as compared with the case where the columns are joined by bolts or only horizontal plates. Then, the respective pillars become the pillars which are substantially integrally combined. Therefore, the rigidity and proof stress for the amount of steel used are significantly improved, and the rigidity and proof stress of the entire unit house are also improved.
