Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated building used for shelters installed on stairs, roofs and the like.

[0002] In this specification, "aluminum" includes aluminum alloy.

[0003]

2. Description of the Related Art Conventionally, a prefabricated building used as a shelter is provided with a rectangular aluminum roof frame and a pair of aluminum columns supporting the roof frame, and the lower ends of the columns are embedded in a concrete foundation. Things are known.

[0004]

In the above-mentioned conventional building, it was not possible to install it on stairs, rooftops, etc. where a concrete foundation cannot be newly installed.

An object of the present invention is to provide a prefabricated building which has sufficient rigidity without being embedded in a concrete foundation and can therefore be used as a shelter installed on stairs, rooftops, etc. is there.

[0006]

A prefabricated building according to the present invention is a prefabricated building having a rectangular aluminum roof frame and at least a pair of aluminum columns supporting the roof frame, and corner pieces are provided at four corners of the roof frame. Is placed
Each roof frame member and the corner piece are fixed to each other. The roof frame and pillars are usually hollow extruded profiles having a substantially rectangular cross section, and the corner pieces are made of metal extruded profiles such as aluminum, for fixing each roof frame member and the corner piece. In, for example, in the corner piece, insert portions that are respectively fitted into the two roof frame members that are butted against each other are formed, and these insert portions are integrally formed with vertical female thread portions that extend in the extrusion direction, Screws penetrating the roof frame member are screwed into these female screw portions.

It is preferable that the upper end of the pillar is cut out in an L shape, and the middle portion of the roof frame member is fitted in the cutout and fixed to the pillar. To fix the roof frame member and the pillar, for example, a vertical female screw portion extending in the extrusion direction is integrally formed on the pillar, and a screw penetrating the roof frame member is screwed into these female screw portions, and Screws are also screwed in from the side of the pillar.

[0008]

In the assembled building according to the present invention, the corner pieces are arranged at the four corners of the roof frame, and each roof frame member and the corner
Since the piece is fixed, the roof has a solid structure and can stand on its own without the bottom end of the pillar being embedded in the concrete foundation.

In the case where the upper end of the pillar is cut out in an L shape and the middle portion of the roof frame member is fitted into this cutout portion and fixed to the pillar, the roof frame is formed only by the pillar from below. Instead, it is supported from both sides, increasing the rigidity of the joint between the roof frame and the pillar.

The connecting portions between the left and right roof frame members (73) and the columns (72) are almost the same as those shown in FIGS. 4 to 6, but the notches (79) of the columns (72) are The only difference is that the bottom slopes according to the slope of the stairs. With such a configuration, in the conventional one in which the roof frame and the pillar are joined by welding using the force bone, the force bone according to the inclination angle needs to be made each time, whereas the pillar It becomes easy to make the mounting angle of the roof frame (71) to the (72) correspond to the inclination angle of the stairs.

The prefabricated building according to the present invention is also used when a smoking room is installed indoors, for example. In this case, it is preferable to install an air conditioner on the roof frame (1). Since each roof frame member (3) (4) and corner piece (5) are fixed by screws (17) and the roof frame (1) is reinforced by braces (7), the roof frame (1) Can withstand the load of an air conditioner.

[0025]

According to the prefabricated building of the present invention, the roof has a rigid structure and can stand on its own without embedding the lower end portion of the column in the concrete foundation. It can be used as a shelter installed on a rooftop or the like.

In the case where the upper end of the pillar is cut out in an L shape and the middle portion of the roof frame member is fitted into this cutout and fixed to the pillar by screws, the roof frame is fixed from below by the pillar. Not only is it supported from both sides, the rigidity of the joint between the roof frame and the pillars is increased, so the roof frame can be supported by two pillars.
