Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure for unit buildings having a plurality of floors.

[0002]

2. Description of the Related Art In a conventional joint structure of a unit building, Japanese Unexamined Patent Publication No. 1-33332 discloses that an anchor bolt installed on a foundation is inserted into an anchor bolt drilled on the bottom of a lower-floor building unit. The lower-floor building unit is installed on the foundation through the hole, and then the upper-floor building unit is placed on the lower-floor building unit, and the building units on the upper and lower floors are connected to each other by connecting bolts.

In the conventional joint structure of unit buildings described in Japanese Patent Application Laid-Open No. H10-280552, a connecting bolt is fixed to a pulling hardware provided on a wall panel or a pillar of a lower-floor building unit. The building units on the upper and lower floors are connected by being tied to floor hardware stored inside the floor structure of the upper floor building unit.

[0004] However, in the above-mentioned conventional joint structure of unit buildings, when building units are stacked on a plurality of floors of two or more floors, connection work is performed for each floor, so that the connection work is troublesome. is there.

Therefore, the present applicant has previously filed Japanese Patent Application No. Hei 10-3
No. 08500 proposes a method for joining unit buildings that does not require much time for connecting work. In this method of joining unit buildings, the building units on the upper and lower floors are laminated on the foundation with guide pins, and then vertically connected with a long connecting material (wire rope, reinforcing bar, etc.) from the foundation to the top of the upper building unit. The building units on the floor are tied together.

[0006]

However, in the method of joining unit buildings described in Japanese Patent Application No. 10-308500, the connecting material is passed through the narrow gap between the adjacent building units on the left and right. In order to secure a predetermined joining strength, the number of connecting members must be increased, and there is a limit in simplifying the joining operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a joint structure of a unit building which can further simplify the joining operation.

[0008]

According to the first aspect of the present invention,
A unit of one or more upper-floor building units stacked on a lower-floor building unit installed on a foundation. A long connecting material extending from the top-floor building unit to the foundation or the lower part of the lower-floor building unit. A joint structure of unit buildings in which building units on floors are tied together, wherein the connecting members are provided inside building units on upper and lower floors.

According to a second aspect of the present invention, in the joint structure of the unit building according to the first aspect, the building unit comprises:
A wall panel or a pillar is erected on the floor structure, and the pulling hardware is fixed to the wall panel or the pillar of the top floor building unit, and one end of the connecting member is placed inside the floor structure of the foundation or the lower floor building unit. It is characterized in that it is fixed to the stored floor hardware and the other end of the connecting member is tied to the pull hardware.

(Operation) According to the first aspect of the present invention,
Since the connecting members are provided inside the building units on the upper and lower floors, the outer size of the connecting members is not limited. For this reason, it is not necessary to increase the number of connecting members in order to secure a predetermined joining strength, and the joining operation can be further simplified.

According to a second aspect of the present invention, the metal fitting is further fixed to a wall panel or a pillar of the top floor building unit, and one end of the connecting member is stored inside the foundation or the floor structure of the lower floor building unit. Since the other end of the connecting member is fixed to the pulled-in hardware, the joining strength between the building units on the upper and lower floors can be further improved.
