Description

[Detailed Description of the Invention] The present invention relates to a prefabricated building consisting of columns, beams, and girder structures using steel pipes.

Conventionally, when buildings such as cattle sheds and garages were constructed with steel frames, fixed structures were used in which members such as columns, beams, and girders made of C-shaped steel or H-shaped steel were connected by welding or rivets. is used.

In the fixed steel structure mentioned above, disassembly,
It is difficult to move, and even if it is forcibly dismantled and moved, each member is heavy, and efficiency in terms of workability and transportability is poor, and a large amount of expense is required. Therefore, if the user wants to move the device, it is necessary to leave it as it is and construct a new building at the new location, which also poses problems such as requiring a large amount of expense.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to form lightweight and strong steel pipes so that columns, beams, girders, etc. can be connected and assembled, and to assemble, disassemble, and To provide a prefabricated building that is easy to move, has excellent workability, transportability, etc., and is inexpensive to construct.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3 show a prefabricated building 11 according to an embodiment of the present invention.

In the figure, a prefabricated building 11 includes a pair of support frames 1 made of steel pipes (hereinafter referred to as single steel pipes), that is, single steel pipes, and formed in an inverted L shape.
a, 1b, a girder frame 7a, 7b made of single steel pipes of a required length, a cane 8 made of a single steel pipe, a corrugated roof plate 9 as a roof member, and a floor. Earthen floor unit 1 as a component
Equipped with 0 etc.

Then, each member is transported to the construction site and the prefabricated building 1 is assembled while connecting each joint part with bolts.
It is assembled as 1.

Figures 2 and 3 show an inverted L-shaped support frame 1.
A portal support frame with joints a and 1b connected is shown. The support frames 1a, 1b have a joint flange 2 fixed to one end of the upper horizontal part, a receiving plate 3 fixed to the lower end of the vertical part, and cane joints 4, 4 fixed to both sides near the upper end. . Further, a girder locking piece 5 made of a pair of opposing plate pieces is provided protruding from the upper end of the vertical portion so as to intersect with the upper horizontal portion and lock the girder frames 7a, 7b. The joint flanges 2, 2 at the upper horizontal parts of the above-mentioned support frames 1a, 1b are connected with bolts to assemble a portal support frame.

As shown in FIGS. 1 and 2, girder frames 7a,
7b has a plurality of single steel pipes in which joint flanges 2, 2 at both ends are connected to each other with bolts, and each of the single steel pipes has a pair of cane joints 4, 4 on its lower surface symmetrical to its center. is provided, and a corrugated receiver 6 is fixed to the upper surface.

When assembling the prefabricated building 11, a plurality of gate-shaped support frames in which the support frames 1a and 1b are connected by joints are erected on the floor, and protrusions are installed at both ends of the upper horizontal part of each gate-type support frame. The center portions of the single steel pipes of the girder frames 7a, 7b, each of which is a jointed single steel pipe, are inserted into the girder locking pieces 5, 5, which are provided, and are locked with bolts.

Next, both ends of the braces 8, 8 are connected with bolts to the brace joints 4, 4 on the vertical part of the portal support frame and the brace joints 4, 4 on the lower surface of the single steel pipes of the girder frames 7a, 7b. A corrugated roof plate 9 is fitted into the corrugated receiver 6 on the upper surface of the girder frames 7a, 7b and secured with bolts.

Furthermore, a rectangular earthen floor unit 1 made of concrete is installed on the upper surface of the receiving plate 3 at the lower end of the vertical part of the gate-shaped frame.
0 is inserted sequentially.

Therefore, in the prefabricated building 11 of the present invention, each member such as the support frames 1a and 1b, the girder frames 7a and 7b, and the cane 8 is made of a single steel pipe that is lightweight and easy to handle. Not only can it be easily transported to the site in a disassembled state, but
Furthermore, since joint flanges and bolts are used to connect each member, assembly and disassembly work itself is easy.

In addition, the single steel pipe as each member is made resistant to rust by hot-dip galvanizing, and in areas near the coast, corrosion of each member due to salt damage can be prevented. Further, if the roof plate 9 is also made of galvalume steel plate and the ceiling surface is covered with a heat insulating material such as hard urethane, the service life can be further increased and a sufficient heat insulating effect can be obtained in the summer.

The earthen floor unit 10 acts as a load plate on the receiving plate 3 at the lower end of the vertical part of the gate-shaped support frame, and can prevent the building from floating up during strong winds.

Although a corrugated roof plate 9 is shown as an example of the roof plate, the roof plate is not limited to this, and various types of roof plates may be used.
Alternatively, it can be used inexpensively as a building that can be assembled, dismantled, and moved, such as in a warehouse.
