Abstract

PURPOSE:To obtain an assembly type construction where columns constituting a unit type steel frame material are not exposed inside of a building constructed with the unit type iron frame member of a specific size which is transportable. CONSTITUTION:Supports 36 of reinforcing frames 11 of outer peripheral parts 60A of a base face 60 of a construction are installed. The upper end part of these supports 36 is made in a rahmen structure connected with beam materials 38, 40. Thereafter, unit type steel frame materials 10 are laid in order on the base face 60. At least one of columns constituting the unit type steel frame materials 10 is to be a temporary support 30. Accordingly, the temporary support 30 can be removed after a ceiling frame 12 of the unit type steel frame material is fixed on the beam material 40 and the ceiling frame 12 is supported by the beam material 40. Additionally, the position and the number of the temporary support 30 of the unit type steel frame materials 10 are considered of in accordance with the position arranged on the base face 60. Consequently, it is possible to construct a large indoor space where no column is positioned inside a building by removing the temporary support 30 positioned inside the building after assembling it.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention relates to a prefabricated building in which a building space is constructed by assembling unit type steel frame members shaped into a box shape at a construction site.

0002

[Prior Art] Currently, in order to speed up construction work,
A unit-type building has been proposed in which a building is constructed by assembling unit-type steel frame materials manufactured in a factory at a construction site (for example, Japanese Patent Laid-Open No. 63-544).

As shown in FIG. 8, this unit type steel frame member 80 has a box-shaped space having a predetermined strength by connecting steel members constituting a ceiling frame 82 and a floor frame 84 with pillar members 86. It is formed.

[0004] Therefore, at a construction site, a frame for constructing a building of a desired size can be easily completed by simply connecting a large number of unit type steel frame members 80 transported from a factory with bolts, etc. I will do it.

[0005]

However, in order to construct the box-shaped unit type steel frame member 80, it is necessary to provide pillar members 86 that support the four corners or at least three locations of the ceiling frame 82. For this reason, a large number of unit type steel frame members 80
When assembled to form a large building, the pillars will inevitably be located inside the building space, making it impossible to construct a functional indoor space.

[0006] To deal with this, even if the empty volume of each unit type steel frame member 80 is increased, there is a load limit on the vehicle that transports it, so it is not possible to transport it from the factory. It is realistically impossible. Therefore, with the conventional unit type steel frame material 80, it has not been possible to construct a prefabricated building in which columns are not exposed inside the building.

[0007] In consideration of the above facts, the present invention provides a prefabricated building in which the columns constituting the unit type steel frame are not exposed inside the building, which is constructed of a unit type steel frame of a certain size that can be transported. The purpose is to provide

[0008]

[Means for Solving the Problems] The prefabricated building according to claim 1 includes a box-shaped unit type steel frame material constructed by connecting a ceiling frame and a floor frame with pillar materials; at least 1
A temporary pillar material whose both ends are temporarily fixed to the ceiling frame and floor frame and can be removed, a pillar erected at the outer edge of the foundation surface on which the unit type steel frame material is laid, and a pillar of this pillar. The reinforcing frame has a rigid frame structure composed of a beam that connects the upper end, and a connecting means that connects the ceiling frame and/or floor frame of the unit type steel frame material and the reinforcing material frame. It is a feature.

The prefabricated building according to the second aspect of the present invention is characterized in that a support plate for temporarily placing the ceiling frame is provided on the beam material constituting the reinforcing frame.

0010

[Operation] In the prefabricated building constructed as described above, first, the supports of the reinforcing frame are installed at the outer edge of the foundation surface of the building. The upper ends of these columns are connected by beams, and the reinforcing frame has a rigid frame structure. Therefore, the vertical load acting on the reinforcing frame is transmitted to the plurality of support columns via the beam members, and they collectively support the applied load. next,
Unit-type steel frame materials are arranged on the foundation surface to construct the framework that forms the building space. Next, the beams of the reinforcing frame and the ceiling frame of the unit type steel frame are connected, and the ceiling frame is supported by the reinforcing frame. After that, the temporary support members are removed from the ceiling frame and floor frame. This eliminates the presence of temporary support materials inside the building, making it possible to secure a large indoor space without pillars located inside the building. By performing this work on each floor, it is possible to easily construct a prefabricated building having a large space.

Furthermore, when constructing a relatively large building using a large number of unit type steel frames, only the ceiling frame is temporarily placed on support plates provided on the beams of the reinforcing frame, and then the beams are By connecting these ceiling frames, it is possible to construct a building with a large space without having to provide temporary struts to support the ceiling frames and remove them after assembly.
