2. Description of the Related Art Conventionally, in a general garage, for example, at a site where a house is newly constructed, a predetermined portion of a residential land facing a road is dug up, a reinforcing bar is assembled at the dug-up portion, and concrete is cast on site to form a section box. A reinforced concrete garage was constructed.

[0003]

Such a reinforced concrete garage requires time and labor to assemble a formwork at the site, assemble the reinforcing steel, pour concrete, and after the concrete has solidified, disassemble the formwork. A complicated process is required, the construction period is long, and there is no flexibility in the size and the like. Therefore, not only the construction cost is increased, but also concrete is cracked and water leaks (such as rainwater into the inside). Intrusions), and it is difficult to repair water leaks.

[0004] The present invention has been made in view of the above-mentioned circumstances, and simplifies on-site work, allows an object of any size to be installed in a short time, and greatly reduces the installation cost. yet as it can, on difficult to water leakage, very easy to cope with emergency water leak occurs
The purpose of the present invention is to provide a steel garage capable of repairing water leakage and having extremely excellent durability.
