Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing plate and a unit building provided with the reinforcing plate.

[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]

However, since the reinforcing beam as described above has a length of two units, there is a problem that it is difficult to transport the beam from a factory to a building site. In addition, since a reinforcing beam having a length of two units must be attached to a large space building unit at a building site, site construction is difficult.

An object of the present invention is to provide a reinforcing plate and a unit-type building that can be easily transported and that can be easily attached to a large space building unit.

[0006]

The reinforcing plate and the unit-type building of the present invention have the following arrangements in order to achieve the above object. More specifically, referring to the accompanying drawings, the reinforcing plate according to claim 1 is a rectangular parallelepiped skeleton in which the upper and lower ends of pillars 31 erected at four corners are connected by ceiling beams and floor beams, respectively. Unit building 1 which includes a normal building unit 3A (3B) having a plurality of large space building units 4A (4B) in which some pillars 42 are omitted from the framework of the normal building unit. When a plurality of large-space building units 45 having columns omitted are arranged adjacent to each other in order to form a large space without pillars in the inside of the space, the adjacent large-space building units are connected and reinforced. The reinforcing plate 7 connects the portions of the adjacent large-space building units where the columns are omitted.

According to the present invention, when a plurality of large space building units are arranged adjacent to each other in order to form a large space without pillars inside the unit type building, the pillars of these adjacent large space building units are omitted. The reinforced parts are connected and reinforced by a reinforcing plate. The reinforcing plate only needs to have a length capable of connecting the portions of the large space building unit where the pillars are omitted (length spanning each large space building unit), so that the conventional two-unit length is used. This makes it easier to transport to the construction site than when a reinforcing beam having the following is used, and also facilitates attachment to a large space building unit at the site.

A reinforcing plate according to a second aspect of the present invention is the reinforcing plate according to the first aspect, wherein the reinforcing plate has a size that straddles a portion of the adjacent large space building unit from which columns are omitted.
Further, it is characterized in that it is formed to have substantially the same size as the contour shape 5 connecting the outside of these portions. According to the present invention, the reinforcing plate has a size that extends between the portions where the pillars are omitted, and has substantially the same size as the contour shape that connects the outsides of these pillar portions, that is, connects the large space building units to each other. Since it is formed in a size sufficient and small enough to reinforce, it is possible to sufficiently connect and reinforce each large space building unit, and to economically configure a reinforcing plate.

A unit building according to a third aspect of the present invention is an ordinary building unit having a rectangular parallelepiped skeleton in which the upper and lower ends of pillars erected at four corners are connected by ceiling beams and floor beams, respectively. A unit-type building comprising a plurality of large-space building units in which some pillars are omitted from the framework of a normal building unit, and a plurality of large-space buildings in order to form a large space without pillars inside. A portion of the large space building unit adjacent to the large space building unit where the columns are omitted is connected and reinforced by a reinforcing plate. According to this invention, the same operation and effect as the first aspect can be expected. That is, when forming a large space inside the unit-type building, the transport of the constituent members can be facilitated and the construction work at the building site can be facilitated as compared with the case where the conventional long reinforcing beams are used.

According to a fourth aspect of the present invention, in the unit type building according to the third aspect, the large space without pillars is formed on the adjacent upper and lower floors, respectively, and the adjacent large space building on the upper floor. Reinforcing plates are provided at substantially the same position in plan view on the inner floor side of the unit 4B and on the ceiling side of the adjacent large space building unit 4A on the lower floor. According to the present invention, when large spaces are respectively formed on the adjacent upper and lower floors, the reinforcing plates are respectively provided at substantially the same positions in plan view on the frameworks of the large space building units installed on the upper and lower floors. In other words, since the structure in which the columns of the large space building units installed on the upper and lower floors are sandwiched from above and below, the connection of the large space building units in which the columns are omitted can be more firmly connected.

According to a fifth aspect of the present invention, in the unit type building according to the fourth aspect, a large space vertically and horizontally adjacent between the large space building units installed on the upper and lower floors. The shear plate 6 for positioning the building unit is provided at substantially the same position as the reinforcing plate in plan view. According to this invention, the connection strength between the large-space building units can be further improved by connecting the portions of the large-space building units where the pillars are omitted in the shear plate in addition to the reinforcing plate.

According to a sixth aspect of the present invention, there is provided the unit-type building according to any one of the third to fifth aspects, wherein the reinforcing plate omits columns of the adjacent large space building unit. It is characterized in that it is sized so as to straddle between the parts and has substantially the same size as the contour shape connecting the outsides of these parts. According to this invention, the same operation and effect as those of the second aspect can be expected. In other words, the building units for large spaces can be sufficiently connected and reinforced, and a large space can be economically formed in the unit building.
