[Problems to be solved by the invention]
However, in such a unit building of the above publication, the overhang member provided on the lower floor unit has a structure that individually supports only the overhang portion of the corresponding upper floor unit. When the floor units are arranged adjacent to each other, there is no linkage between the support structures of the adjacent overhang parts, so when a horizontal force acts on the unit building, the adjacent overhang parts There is a problem that a displacement displacement is likely to occur between the front end portions.
[0006]
In addition, when the structure of joining the end of the horizontal brace material to the pillar of the lower floor unit as a reinforcement of the overhang part as a reinforcement of the pillar of the lower floor unit and the lower beam of the upper floor unit, There was a problem that these were mixed to form a complicated structure.
[0007]
Furthermore, when the lower floor unit's wife joint piece is joined to the upper floor unit, it becomes impossible to join from the outside of the building unit, so it becomes necessary to cut out the floor board directly above the joint part. There was a problem that allocation was complicated.
[0008]
Accordingly, an object of the present invention is to provide a building unit joint fitting that can solve the above-described problems and can simplify the structure and facilitate the floorboard assignment.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problem, in the invention described in claim 1, a building unit that joins a lower-floor building unit and an upper-floor building unit placed in an overhanging state on the upper portion of the lower-floor building unit. A lower metal column joint that can be bonded to the upper end side surface of the unit column of the lower floor building unit, and an upper floor lower beam joint that can be bonded to the lower beam of the upper floor building unit, It is characterized by a joint fitting for a building unit that is integrally provided with a brace material joint that can join the end of the brace material.
[0010]
According to the invention concerning Claim 1 comprised in this way, three joining functions, the joining function with a lower floor pillar, the joining function with an upper floor lower beam, and the joining function with a brace material, are made into one metal fitting. By summarizing, the delivery is simplified and the cost can be reduced. Further, since the joining work from the outside of the building unit is possible, it is not necessary to cut out the floor board immediately above the joining part, and the floor board assignment becomes easy.
