Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof structure, and in particular, it can be used to cover a main structural material of a building unit or a space between adjacent main structural materials of a unit building with a fireproof material.

[0002]

BACKGROUND ART As shown in FIGS. 1 and 2, a unit building 4 is constructed by combining a plurality of building units, for example, first floor, second floor, and third floor building units 1, 2, and 3 at a construction site. Here, each building unit 1 and the like includes four columns 10 at four corners and upper and lower beams 11 and 12 connecting the upper ends and the lower ends of the columns 10 with each other.
A ceiling material, a floor material, a wall material 14 and the like are preliminarily attached to a skeleton 13 made up of in a factory to have a substantially box shape.

Among such unit buildings, three-story or more buildings for use in apartment houses, hospitals, hotels, etc., have main structures such as columns, beams, floors, walls, and roofs in accordance with the Building Standards Act. It is required that the part has a fireproof structure having a predetermined fireproof performance. Therefore, in general, floor materials, ceiling materials, and wall materials are made of refractory materials,
The roof is covered with refractory material, and the pillars and beams are covered with refractory material to meet the above requirements.

Among these, particularly as a refractory structure in which a main structural material of a building unit or a space between adjacent main structural materials of a unit building is covered with a refractory material, asbestos as a refractory material corresponding to the shape of the main structural material is used. It is known that cement calcium silicate (silica plate) is directly attached and covered between the main structural materials by nailing or the like.

[0005]

However, when a silica plate is directly attached between the main structural materials of the building unit or between the adjacent main structures of the unit building, especially between the lower beams of the building units, there is a gap between the lower beams. Therefore, when a large load is applied to the calcareous plate, it may be cracked from the gap. Then, when a fire occurs, the fire penetrates through the damaged portion and the fireproof structure cannot be fulfilled.

It is an object of the present invention to increase the strength of the refractory material so that the refractory material can be attached without damage to the main structural material of the building unit or between adjacent main structural materials of the unit building. To provide.

[0007]

Therefore, the present invention is a fire resistant structure in which a main structural material of a building unit or a space between adjacent main structural materials of a unit building is covered with a fire resistant material, and the inner surface of the fire resistant material is provided with the fire resistant material. A fireproof structure is provided in which a reinforcing member having a size covering the entire area where the material and the main structural material contact each other is attached.

[0008]

According to the present invention as described above, the refractory material having the reinforcing member formed on the inner surface of the main member of the building unit or between the adjacent main members of the unit building is sized to cover the entire area in contact with the main member. Covered by. Since the inner surface of the refractory material is reinforced by the reinforcing member, the strength of the refractory material is increased and damage to the refractory material can be prevented.
