Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary reinforcing structure for a building unit by applying a wall type construction method, and more particularly, to a building unit that is damaged or deformed during transportation or lifting at a construction site. So as not to exist, it relates to a temporary reinforcement structure for adding reinforcement to the building unit until the installation on the foundation is completed.

[0002]

2. Description of the Related Art Generally, a wall type construction method is known in which a structural panel is struck on each frame of a floor and a wall to form a floor panel and a wall panel, and the floor panel and the wall panel are assembled into a box-shaped structure. . According to this wall type construction method, an external force is evenly supported on the entire floor and the entire wall, and high structural strength can be obtained, as compared with the case of the frame construction method consisting of columns and beams. . A unit building method is known as one method for increasing the industrial production rate of a building. In the case of applying the above wall type construction method to a unit building, a plurality of building units each having a wall panel erected on the side edge of the floor panel should be constructed so that one building has an appropriate size for transportation. ,
After each building unit is divided into a roof unit joined to the upper part and each unit is produced in a factory, these units are transported to a construction site and installed on a foundation prepared in advance.

By the way, in a unit building to which the wall construction method is applied, generally, a plurality of building units are connected to each other on a foundation so that a plurality of floor panels are combined to form one unit. Since it is a room, at least one side surface of the building unit is not provided with a wall panel and is normally an open surface. That is, this type of building unit is generally a U-shaped wall unit in which wall panels are erected on three side edge portions of a floor panel,
An L-shaped wall unit in which a wall panel is erected on two side edges of a floor panel that intersect each other, or a two-shaped wall in which a wall panel is erected on two opposite side edges of a floor panel. It is formed as a unit or the like, and there are one open surface in the U-shaped wall unit and two open surfaces in the L-shaped wall unit and the two-shaped wall unit. Therefore, the wall panel and floor panel that intersect the open surface lack structural stability, and the wall panel and floor panel may be deformed or damaged by a large external force applied during transportation or lifting at the construction site. There is a fear of doing it.

As a means for improving such inconvenience, a temporary reinforcing structure for a building unit as described in JP-A-60-33959 has been known. As shown in FIG. 9, the temporary reinforcement structure described in the above publication discloses a vertical side edge portion of a wall panel 1 forming a vertical side of an open surface of a building unit and a horizontal side edge of a floor panel 2 forming a bottom side of the open surface. The truss reinforcement body is assembled by diagonally bridging the temporary reinforcement member 3 between the wall part and the part, and the wall panel 1 falls inward or outward until the installation on the foundation is completed. Etc. are prevented. Here, in order to avoid interference between building units arranged adjacent to each other on the foundation, the upper end portion of the reinforcing member 3 is a side surface of the vertical frame 4a forming the vertical side edge portion of the wall panel 1. It is internally attached by nailing to a portion facing the adjacent vertical frame 4b, while the lower end portion is a side surface of the side joist 5 forming the horizontal side edge portion of the floor panel 2 and adjacent to the joist 6 next. It is designed to be internally attached to the facing part by nailing.

[0005]

However, in the structure described in the above publication in which the end portions of the reinforcing member 3 are nailed to the inner surfaces of the side edge portions of the wall panel 1 and the floor panel 2 for internal attachment, It is necessary to find a working clearance in the wall panel 1 or floor panel 2 for nail removal or the like. Therefore, conventionally, between the vertical frame 4a and the adjacent vertical frame 4b, and between the side joist 5 and the adjacent joist 6 at the factory stage, the (inner) wall material 7 and floor material 8 are not attached. After opening the work clearance, the reinforcing member 3 is removed at the site, and then the wall material 7 and the floor material 8 are provided at the places that were left as the work clearance.
Since it was supposed to be attached, it caused a burden of on-site construction labor. In addition, as described above, since there is a portion where the wall surface material 7 and the floor surface material 8 are not partially adhered to the inner surface of the wall panel 1 or the upper surface of the floor panel 2 as the work clearance, there is a certain amount of clearance. There was also an inconvenience that fabrication (for example, bringing in a system kitchen and assembling storage furniture) could not be done at the factory stage. Furthermore, when the reinforcing member is temporarily installed, it is difficult to carry in the system kitchen or the like.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to sufficiently attach the floor surface material and the wall surface material in advance at the factory, and further, to carry in the bus unit or to assemble the storage furniture. The purpose is to provide a temporary reinforcement structure for a building unit that does not hinder the situation.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 is such that a wall panel is erected on one of two side edges of the floor panel which intersect each other and an open surface is provided on the other. A temporary reinforcement structure of a building unit in which the floor panel outermost edge forming the bottom of the open surface and the vertical frame of the wall panel outermost edge forming the standing side of the open surface are formed. In addition, the reinforcing member is laid across diagonally, and the upper end of the reinforcing member is externally attached by being joined by a fixture to the side surface of the outermost edge of the wall panel on the side surface of the vertical frame and the rear surface of the adjacent vertical frame. On the other hand, the lower end portion of the reinforcing member is detachably tightly connected to an externally attached bracket which is joined by a fixing tool to a portion of the floor panel outermost edge which is the side surface of the joist and is behind the adjacent joist. It is characterized by being.

[0008]

According to the structure of the present invention, the upper end of the reinforcing member is externally attached to the vertical side edge of the wall panel forming the vertical side of the open surface, and similarly, the lower end of the reinforcing member has the base of the open surface in advance. Since it is tightly connected to the bracket externally attached to the horizontal side edge of the eggplant floor panel, it is not necessary to obtain a working clearance in the wall panel or floor panel for nailing or pulling nails. Therefore, it becomes possible to sufficiently attach the wall surface material and the floor surface material in advance in the factory. As a result, it is possible to carry out production such as carrying in bus units and building storage furniture at the factory, so overall, while increasing the industrial production rate of the unit building, reduce the on-site construction labor. Can contribute to. Furthermore, since it is possible to place the receiving object externally on the horizontal side edge portion of the floor panel in advance, after that, between the line stage (workbench in the factory) and the work (floor panel). Even if there are no gaps or steps,
For example, it becomes easy to temporarily install the reinforcing member immediately after carrying in the system kitchen or the like.
