2. Description of the Related Art In recent years, a unit construction method which has been frequently used for construction of a building such as a house is based on a method in which a modular building unit such as a living room unit, a roof unit or the like, in which various components constituting the building are assembled, is previously prepared. A factory is produced, and at a construction site, a plurality of living room units are arranged at predetermined positions on a foundation, and a plurality of roof units are arranged on these living room units to construct a unit building.
Such a unit construction method has the advantage of simplifying the work on the construction site and shortening the construction period.

In the case of constructing a unit building on the third floor or higher using such a building unit, the main structural material of the pillars and beams of the building unit is coated with a refractory material such as calcium silicate plate from the viewpoint of disaster prevention. Is required. Conventionally, of the refractory material coated on the main structural material of the building unit, the part that can be coated at the time of manufacturing the building unit has been coated with the refractory material at the building unit manufacturing plant.

On the other hand, two or more columns and beams are in close proximity to each building unit after the building units are arranged.
Since these columns and beams cannot be coated with the refractory material at the factory in advance, it was unavoidable to coat the refractory material after arranging the building unit at the construction site. Therefore, the refractory material was transported to the construction site together with the building unit, and coating work was performed at the construction site.

[0005]

However, since the refractory material is made of a brittle material such as calcium silicate plate, cracking occurs due to vibration during transportation to the construction site or impact during unloading from the truck. It has the drawback of being easy. In addition, driving nails and screws into main structural materials such as pillars and beams at the construction site in order to coat the refractory material is complicated and causes a delay in the construction period due to heavy labor. Further, even after the main structural material was coated with the refractory material, the exposed corner portions of the refractory material were likely to be impacted and cracked easily.

The present invention has been made in view of the above circumstances, and when the refractory material is coated on the main structural material of the building, the refractory material is not cracked during transportation and after the coating, and the refractory material is formed. An object of the present invention is to provide a refractory material coating structure for a building, which can easily and quickly coat the main structural material of the building.

[0007]

According to the present invention, in a factory, at one end of a plate-shaped refractory material, a protective piece covering the outer surface of the one end and from the protective piece along the end face of the one end,
In addition, a connecting metal fitting having a connecting piece formed to a length projecting from the end face is attached, and a plurality of refractory materials with the connecting metal fittings are transported to a construction site, and around the main structural material of the building at the construction site. A plurality of refractory materials are sequentially arranged along the tongue-like shape so that the end surface of the other end portion of the other refractory material faces the inner surface of the one end portion of the adjoining one refractory material, and the connecting piece of each refractory material. The other end of the refractory material adjacent to this is fixed to each other.

[0008]

In the present invention, a protective piece covering the outer surface of one end of a plate-shaped refractory material is attached to one end of the plate-shaped refractory material.
For this reason, one end of the refractory material is protected from vibration, impact, etc. when the refractory material is transported to the construction site and is not cracked. In addition, this protective piece is provided with a connecting piece formed to have a length protruding from the end surface of one end, and at the construction site, the connecting piece of one refractory material is fixed to the other end surface of the other refractory material. Each refractory material is arranged in a tongue-like shape in order to cover the periphery of the main structural material. Therefore, the work of connecting the refractory materials is facilitated, and one end and the other end of the coated refractory material are covered and protected by the connecting fittings.
