SOLUTION: A horizontal brace 50 arranged between the head parts of columns 21 positioned on the diagonal line of a ceiling horizontal plane of structure is arranged at a standard building unit 11 and a column elimination building unit 12. A mounting member 51 of the brace 50, a column fixing plate 52 and a brace fixing plate 53 are constituted through integral forming structure by welding and fixed by a bolt 54B welded to the side of the head part of a column 21A mounting piece 50A of the brace 50 is attached to a brace fixing plate 53 by a bolt 56. When a horizontal force is exerted on the horizontal plane of structure arranged at the brace 50 of a ceiling by effecting setting such that the extension line of the brace 50 coincides with the core of a column 21, a column 21 is prevented from being twisted by the tensile force of the brace 50 and a given strength for the units 11 and 12 is ensured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit and a unit building, and more particularly to a building unit and a unit building in which a horizontal brace is provided on a horizontal construction surface of the building unit.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Patent Publication No. 61-42061, as a building unit that constitutes a unit building, columns, floor beams, and ceiling beams are joined in a box shape, and they are located on a diagonal line of a horizontal construction surface. A horizontal brace is provided between the ends of the pillar. Further, in the prior art, as a mounting member to the column end portion of the horizontal brace, one using a brace fixing plate fixed around the column and having its plate surface arranged in the vertical plane is adopted. Further, in the prior art, in order to improve the strength of the building unit, a reinforcing frame body, in which the vertical members facing each other are joined to the rigid frame structure by the horizontal members, is attached between the beams facing each other at the top and bottom of the box-shaped frame. ing.

[0003]

However, the prior art has the following problems. The extension line of the horizontal brace is off the core of the column. Therefore, when a horizontal force acts on the horizontal structure of the ceiling or floor of the building unit where the horizontal brace is installed, the column core is not on the extension line of the horizontal brace, so the column is twisted by the tensile force of the horizontal brace, The torsional deformation of the column is transmitted to the beam, and it is impossible to secure a predetermined strength in the building unit.

In the case where the reinforcing frame is provided between the beams facing each other on the upper and lower sides of the building unit, the presence of the reinforcing frame narrows the degree of freedom in the plan of the building.

Since the brace fixing plate as the horizontal brace mounting member has its plate surface arranged in the vertical plane, the brace fixing plate closes the side of the ceiling beam joined to the pillar head. There is. Therefore, as proposed by the applicant in order to improve the strength of the building unit without narrowing the degree of freedom of the plan of the building, in the case where a reinforcing beam is to be attached to the side surface of the ceiling beam, The presence of the brace fixing plate hinders the use of stiffener mounting tools. For this reason, the horizontal brace attachment member is attached after the reinforcing beam is solidly attached to the ceiling beam, which increases the number of on-site work steps and reduces the factory production rate of the building.

An object of the present invention is to provide a horizontal brace on a building unit without adversely affecting the structural strength of the building unit.

Another object of the present invention is to prevent the horizontal brace mounting member from obstructing the mounting of the reinforcing beam on the side surface of the ceiling beam.

[0008]

According to a first aspect of the present invention, a column, a floor beam, and a ceiling beam are joined in a box shape, and a horizontal brace is provided between column end portions located on a diagonal line of a horizontal construction surface. In the building unit to be provided, the extension line of the horizontal brace is made to coincide with the pillar core.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, the mounting member of the horizontal brace comprises a column fixing plate and a brace fixing plate, and the column fixing plate is provided on the side surface of the column. Attached and fixed, the brace fixing plate is fixed to the column fixing plate and its plate surface is arranged in the horizontal plane,
A brace mounting hole is provided.

The present invention according to claim 3 is such that, in a unit building constructed by installing a plurality of building units adjacent to each other, the building unit according to claim 1 or 2 is used. .

According to a fourth aspect of the present invention, in addition to the third aspect of the present invention, the ceiling beams on one side to the other side of the ceiling beams on one side located in the same plane of the adjacent building units as each other. Reinforcement beams extending over the side surfaces of the ceiling beams are fixed to those ceiling beams.

According to a fifth aspect of the present invention, in the present invention according to the third aspect, at least one column omission corner portion defined in each of the adjacent building units is mutually connected by a column omission joint portion. Reinforcing beams that are butt-positioned and that extend from the side surface of the ceiling beam on one side to the side surface of the ceiling beam on the other side located in the same plane including the column omitted joints of the adjacent building units are fixed to those ceiling beams. It was made to do so.

According to the present invention described in claims 1 to 5, the following effects are obtained. The extension of the horizontal brace is aligned with the pillar core. For this reason, when a horizontal force acts on a horizontal structural surface on which the horizontal braces of the ceiling and floor of the building unit are installed, the column is not twisted by the tensile force of the horizontal brace, and the building unit can have a predetermined strength. Therefore, it is possible to obtain a building unit having a required strength without significantly restricting the degree of freedom of the building plan.

According to the present invention described in claims 2 to 5, the following effects are obtained. Since the brace fixing plate as the horizontal brace mounting member has its plate surface arranged in the horizontal plane, the brace fixing plate does not block the side of the ceiling beam joined to the pillar head. Therefore, when a reinforcing beam is to be attached to the side surface of the ceiling beam in order to further improve the strength of the building unit, the presence of the brace fixing plate does not prevent the use of the reinforcing beam installation tool. For this reason, the horizontal brace attachment member can be attached before fixing the reinforcing beam to the ceiling beam, which can reduce the number of on-site work steps and improve the production rate of the building factory.
