Abstract

PROBLEM TO BE SOLVED: To provide a reinforcing beam and a such unit type building that building units for a large space can be surely positioned relative to each other. SOLUTION: Reinforcing members 64 are provided at the intersection of a reinforcing beam body 61 and a shear plate and at the connected intersection of a stiffener 62 and the shear plate 63. Thereby the strength of the parts of the shear plate 63 can be increased and the rate of curving of the shear plate 63 can be reduced. Because the reinforcing members 64 are provided along the longitudinal direction of the reinforcing beam body 61, the strength of the overall reinforcing beam 6 can be increased. Therefore, use of such a reinforcing beam 6 assures positioning of the large space building units 4A and 4B relative to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a reinforcing beam and a unit-type building provided with the reinforcing beam.

[0002]

2. Description of the Related Art Conventionally, there has been known a unit-type building constructed by combining a plurality of box-shaped building units manufactured in a factory at a building site. As a building unit forming a unit-type building, a building unit having a rectangular parallelepiped frame in which upper and lower ends of pillars erected at four corners are connected by ceiling beams and floor beams, respectively, is generally used. If a plurality of such building units are combined to form one large living room, a large space without pillars cannot be formed because a plurality of pillars are concentrated at the center.

[0003] For this reason, a method has been adopted in which a large space is created by combining a plurality of building unit units (hereinafter referred to as large space building units) in which some of the columns are omitted from the framework of a normal building unit. However,
When such a large space building unit is used, since the columns are partially omitted, the rigidity of the frame is reduced, and there is a possibility that the load of the building unit or the like placed above cannot be supported. In order to solve this, the space between the upper ends of the columns of the large space building units arranged on both sides is set to be two spans, that is, the length of the two units, with the part where the part of the column is omitted as the center. It has been proposed to connect and reinforce with a reinforcing beam (see Japanese Patent Application Laid-Open No. 8-277580).

[0004] When a unit-type building is constructed, it is necessary to position each adjacent building unit. In a normal building unit, one metal plate (hereinafter referred to as a "shear plate") having holes corresponding to these positioning pins is formed on positioning pins protruding from the corners of the building units. This is done by plugging in from above. Here, when forming a large space without pillars inside a unit-type building, it is conceivable to connect and reinforce adjacent large space building units while using the conventional positioning technology described above. Specifically, it is conceivable to attach a shear plate to a reinforcing beam having a length of two units.

[0005]

When the shear plate is attached to the reinforcing beam as described above, the joining between the reinforcing beam and the shear plate is performed by joining one side of the shear plate to the reinforcing beam by welding or the like. There is. In such a case,
The shear plate may bend due to the load of a building unit or the like placed above. Further, if the shear plate is curved, there is a problem that the positioning of the large space building units cannot be performed reliably.

SUMMARY OF THE INVENTION An object of the present invention is to provide a reinforcing beam and a unit-type building capable of reliably positioning a large space building unit.

According to the present invention, the reinforcing member is provided at each intersection of the reinforcing beam main body and the stiffener of the shear plate. That is, since the reinforcing member is provided at each of the two joining portions of the shear plate, the joining strength thereof can be further improved. Further, for example, if a reinforcing member is provided at each intersection having a certain length, the shear plate can be provided in at least two directions (a direction along the longitudinal direction of the reinforcing beam main body and a direction along the stiffener). Since the degree of curvature can be reduced, the positioning of the large space building units by the reinforcing beams can be more reliably performed.

According to a third aspect of the present invention, in the reinforcing beam according to the first or second aspect, the reinforcing member is arranged so as to be located between the adjacent large space building units. It is a reinforcing beam characterized by the following.

Further, since the reinforcing member 64 is provided at the intersection having a certain length, the degree of curvature of the shear plate 63 can be reduced. Further, since the reinforcing members 64 are provided along the longitudinal direction of the reinforcing beam main body 61, the strength of the entire reinforcing beam 6 can be improved. Therefore, by using such a reinforcing beam 6, the large space building unit 4 can be used.
Positioning between A and 4B can be reliably performed.

A reinforcing member 64 is provided at each intersection of the reinforcing beam main body 61 and the stiffener 62 of the shear plate 63.

In the above-described embodiment, the reinforcing beam main body 61 is formed in a plate shape. However, the reinforcing beam main body according to the present invention is not limited to this. It may be formed. However, if the reinforcing beam main body is formed in a plate shape, the weight of the reinforcing beam main body can be reduced, and interference with the framework of the large space building unit can be prevented.

In the above embodiment, the reinforcing beams 6 are installed between the short side ceiling beams 43A and the floor beams 44A where the large space building units 4A and 4B are brought together. It may be installed between the beams 44B. However, reinforcing the short side ceiling beams 43A with the reinforcing beams 6 can ensure higher rigidity than reinforcing the long side ceiling beams 43B.

In the above embodiment, the reinforcing beam deformation preventing means 7
Is provided, but the case where it is not provided is also included in the present invention. However, if such reinforcing beam deformation preventing means is provided, the bending of the reinforcing beam main body can be prevented.
