Description

[Detailed description of the invention] The present invention is a steel plate suitable for use as a peripheral wall of a simple assembly house such as a steel plate pet house, a small steel plate storage shed, a civil engineering building, a temporary small building such as a temporary toilet installed at a construction site, etc. It provides a peripheral wall.

When assembling a rectangular peripheral wall that can be assembled and disassembled freely using the front, rear, left and right side walls made of steel plates, etc. and pillars installed at the four corners of these walls, the connections between each side wall and the pillars are made using bolts and nuts. This is usually done by screwing, etc.

However, in the past, screws were fastened on site, which required tools, making assembly and disassembly complicated and time-consuming, and when disassembled, small parts such as bolts and nuts were removed. Since they fall apart, it is troublesome to store them, and bolts, nuts, etc. are easily lost when disassembled or transported to the site.

The present invention eliminates these drawbacks and develops a peripheral wall made of steel plate that looks good and prevents rainwater from penetrating.The present invention is designed to eliminate these drawbacks and develop a peripheral wall made of steel plate that looks good and prevents rainwater from penetrating. , on the inner side of each pillar, an inwardly bent piece of one of the side walls adjacent to each other at right angles is bolted, and a gap is formed between the head of the bolt and the inwardly bent piece. A hole with a diameter larger than that of the bolt head and a hole with a smaller diameter connected above the bolt head are provided in the other side wall. It is characterized in that a small diameter hole portion of the hole is fitted and locked to the bolt within the gap.

According to the above configuration, if the inwardly bent piece of one side wall and the inner surface of the column are tightened and fixed in advance with bolts, no tools are required for subsequent assembly and disassembly, making it easy and quick. Since it can be assembled and disassembled and the bolts do not come apart, it is easy to store and there is no risk of losing the bolts.

Moreover, the inwardly bent piece of one side wall is tightened and fixed to the inner side surface of the column with a bolt, and the small diameter hole of the different diameter hole formed in the other side wall is connected to the inwardly bent piece and the head of the bolt. Since the bolt is fitted and locked within the gap between the bolt and the side wall, the head of the bolt and the side edge of the side wall are not exposed to the outside, making it possible to assemble the peripheral wall with an attractive appearance. Since the end of the other side wall overlaps the inside of the inwardly bent piece formed on the side, there is no risk of wind and rain blowing straight through this overlapping part, and rainwater can be prevented from penetrating.

Therefore, it is suitable as a peripheral wall of a simple assembly house.
