Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated building having an approach, a porch such as a vehicle approach, and an arched roof such as an arcade.

In this specification, the term "aluminum" includes aluminum alloy as well as pure aluminum.

[0003]

2. Description of the Related Art For example, an arch-shaped roof used for a porch such as a car approach is considerably large and requires a considerable amount of strength. Therefore, a steel material such as a shaped steel is usually used as the structural material. ing. Therefore, the right and left lateral frame members having a convex arc shape and a plurality of horizontal rails that are supported between the pair of horizontal front and rear vertical frame members to support the edge of the roof plate are formed by bending the steel material. Needed to be formed.

[0004]

However, as the thickness and thickness of the steel material increase in order to secure the strength, it becomes difficult to accurately bend the steel material, which causes a problem in manufacturing.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a prefabricated building in which it is easy to manufacture a convex arc-shaped structural material forming a part of the frame of an arch-shaped roof. Has an aim.

[0006]

In order to achieve the above-mentioned object, the present invention has an arch-shaped roof, and the roof is fixed between a pair of horizontal front and rear vertical frame members. In a prefabricated building that has both right and left lateral frame members in the shape of a convex arc that supports the edge of the roof plate and a plurality of horizontal bars of the same shape, the left and right lateral frame members and each horizontal bar are made of aluminum profile. In addition, a convex arcuate reinforcing member made of steel is joined to the lower portions of the left and right lateral frame members and all or some of the horizontal rails.

According to the above-mentioned prefabricated building, with respect to the lateral frame members on both sides and the horizontal rails, due to the presence of the reinforcing members, sufficient strength can be obtained without increasing the thickness or thickness of the lateral frame members and the steel members. Since it is made of an aluminum profile that is easier to bend compared to, it is easier to bend into a convex arc shape and the dimensional accuracy is also improved. Similarly, since the reinforcing member is also used in combination with the horizontal frame member and the horizontal crosspiece, its thickness and thickness do not have to be so large, and there is no difficulty in bending. It is also possible to form a fireproof structure by applying a fireproof coating such as a glass mat on the surface of the reinforcing member made of steel.

From the standpoint of the strength of the roof, it is preferable that the reinforcing member is joined to the lateral frame members on both sides and all the horizontal rails. However, since it is necessary to reduce the weight of the roof, the strength and weight of the roof are required. In consideration of the balance with the above, the reinforcing member may be joined to both lateral frame members and an appropriate part of the horizontal rails.
