Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for coating a refractory material on a building, and more particularly to a method for coating a refractory material on a main structural material such as a pillar or a beam of a building unit constituting a unit building. The present invention relates to a refractory material coating method.

[0002]

[Background Art] In recent years, the unit construction method, which has come to be widely used in the construction of houses and the like, uses a modular building unit such as a living room unit and a roof unit in which various parts constituting the building are assembled in advance. A unit building is constructed by factory-manufacturing and arranging a plurality of living room units at predetermined positions on a foundation and arranging a plurality of roof units on these living room units at a construction site.
Such a unit construction method has the advantages of simplifying the work at the construction site and shortening the construction period.

In the case of constructing a unit building of three or more floors using such a building unit, the main structural material of the pillars and beams of the building unit is coated with a fireproof 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 portion 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 to cover the refractory material is a complicated and labor-intensive cause of delaying the construction period. 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 easily cracked.

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 fireproof material coating method 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]

According to the present invention, in the factory, a protective piece is attached to one end of the plate-shaped refractory material to cover the outer surface of the one end.
Therefore, 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, so that the periphery of the main structural material is covered. Therefore, the work of connecting the refractory materials to each other is facilitated, and one end portion and the other end portion of the coated refractory material are covered and protected by the connecting fittings.

Embodiments of the method for coating a refractory material for a building according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view of a refractory material and a connecting fitting used in a method for coating a refractory material for a building according to an embodiment of the present invention. FIG. FIG. 3 is a schematic plan view of a case where a part of the pillar is covered, and FIG. 3 is a cross-sectional view of a main part showing the relationship between the refractory material and the pillar of FIG.

As shown in FIG. 1, the refractory material 10 of the present embodiment.
On the outer surface of the one end portion 10A, the connecting fitting 12 is attached vertically with screws 14. The connecting fitting 12 is
The protective piece 12A has a substantially U-shaped cross section and a connecting piece 12B, and the protective piece 12A is attached so as to cover the one end 10A of the refractory material 10, thereby covering the outer surface of the one end 10A. ..

The connecting piece 12B is formed so as to project from the end face of the one end 10A of the refractory material 10. The other end 10B of the adjacent refractory material 10 is fixed to the connecting piece 12B when the refractory material 10 is covered, and has a role of connecting the two refractory materials 10 to each other.

On the other hand, a unit building constructed by the unit construction method is constructed by sequentially stacking a plurality of building units 16 at a construction site, as shown in FIG. The building unit 16 is formed in a box shape by vertically arranging columns 18 at four corners and erection beams 20 between upper ends and lower ends of the columns 18.

As shown in FIG. 2, between the four building units 16 after the placement, there are places where four pillars 18, which are the main structural members, gather close to each other. This part could not be covered with the refractory material at the time of manufacturing the building unit 16 in the factory, and the work had to be performed at the construction site. When the refractory material 10 of FIG. 1 is used to cover the pillars 18 and the refractory material 10 is covered, the procedure is as follows.

First, in a factory, as shown in FIG. 1, a connecting metal fitting 12 is attached to one end 10A of a refractory material 10 with screws 14 in the vertical direction. And this connecting fitting 12
The plurality of refractory materials 10 attached with are transported to a construction site together with materials necessary for constructing a unit building such as a building unit 16. Next, as shown in FIG. 2, the building unit 16 is arranged at a predetermined position, the construction work of the unit building is sequentially advanced, and adjacent building units 16 are connected by a connecting means (not shown).

As a result, the four pillars 18 are in close proximity to each other at the boundary of the four building units 16 after the arrangement. Then, as shown in FIG. 3, the refractory materials 10 are sequentially arranged around the pillars 18, and a total of four refractory materials 10 are connected in a toe-like shape to cover the surface of the pillars 18.

These two adjacent refractory materials 10 are connected to each other by connecting one end portion 10A of one refractory material 10 and the other end portion 10B of the other refractory material 10 to each other. That is, the end face of the other end portion 10B of the other refractory material 10 is brought into contact with the connecting piece 12B of the connecting metal fitting 12 attached to the one end portion 10A so as to face the screw piece 22B from the surface of the connecting piece 12B.
The other refractory material 10 is fixed to the other refractory material 10 by driving.

Then, the refractory materials 10 are sequentially connected like a toe, and the refractory materials 10 are coated around the four pillars 18. The other end 10B of each refractory material 10 after connection is covered by the connecting piece 12B of the connecting fitting 12, and one end portion 1 of each refractory material 10 is covered.
0A and the other end 10B are protected by the connecting fitting 12.

As described above, according to the building fireproof material coating method of the present embodiment, the one end portion 10A of the fireproof material 10 is protected by attaching the connecting fitting 12 in advance at the factory. For this reason, the refractory material 10 is prevented from vibration during transportation.
Can be prevented from cracking. In addition, after coating the refractory material 10, one end portion 10 of each coated refractory material 10
A and the other end 10B are covered by the connecting fitting 12, and the refractory material 10 can be protected from the impact applied to the one end 10A and the other end 10B. Furthermore, the connecting piece 12B
Since the adjacent refractory materials 10 are connected to each other through the connection, there is an advantage that the connection operation of the refractory materials 10 can be facilitated as compared with the conventional case where the screws are directly driven and fixed to the pillar.

In this embodiment, the protective piece 12A of the connecting fitting 12 has a substantially U-shaped cross section, but the invention is not limited to this, and the L-shaped cross section may be used to replace the adjacent refractory material 10. The end face of the end portion 10B may be brought into direct contact with the one end portion 10A of the refractory material 10 to be connected. Further, although the present embodiment has described the case where the refractory material 10 is covered over the four pillars 18, the number of covered pillars may be any number, and the main structural material to be covered is not limited to the pillars. Anything such as a beam may be used.
