Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing material for improving the fire resistance of face materials such as ceiling plates and wall plates.

[0002]

2. Description of the Related Art For ceiling boards, wall boards and the like in buildings, cheap and easily workable surface materials such as gypsum board and rock wool sound absorbing board are often used. However, these face materials are generally thin and have problems in fire resistance and strength. For example, in the case of gypsum board, when the temperature rises due to a fire or the like, the heat-shielding effect is exhibited by the endothermic reaction accompanying the release of crystal water, but once the crystal water is released, the strength drops significantly. As a result, cracks may occur or some of them may fall off, and the heat shielding effect and even the flame shielding effect may be significantly impaired. Also, in the case of rock wool sound absorbing board, cracks and falling off at high temperature like gypsum board are unlikely to occur, and a flame shielding effect at the time of fire can be expected, but since the strength of itself is low, people and things often When it is used for a wall or the like that comes into contact with, it is easily damaged, and therefore the use site is limited to the non-contact site such as the ceiling.

[0003]

Conventionally, as a fireproof structure of a building, by improving the fireproof performance of a face plate such as a ceiling plate or a wall plate, the steel frame structure can be protected from the heating of a fire or the face plate can be protected. There is a thing that suppresses the fire from spreading and spreading the fire, but when trying to improve the fire resistance performance of the plaster board or rock wool sound absorbing plate described above, it is possible to stack them in layers or to increase the thickness. The method of making it sufficiently thick was adopted, resulting in poor workability and soaring material costs.

In view of the above, it is an object of the present invention to provide a face material reinforcing structure which can improve the fire resistance performance of the face material at low cost and without impairing the workability.

[0005]

In order to solve the above-mentioned problems, the present invention is designed so that the joints of face materials adjacent to each other, to which thin metal plates having fire resistance are adhered, extend between these metal plates. A joint material having fire resistance, and by fixing this joint material with the metal plate from the face material side or fixing it to the face material with a fixing tool, the adjacent metal plates are made continuous through the joint material. It is characterized by that.

Further, a joint material having fire resistance is attached to joints of face materials adjacent to each other on which thin metal plates having fire resistance are adhered, and a joint material having fire resistance is attached between the metal plates. It is characterized in that the metal plates adjacent to each other are connected through the joint material by fixing the metal plate and the joint material to the base material with a fixing tool that is driven in or screwed in from the side of the face material.

Further, the joint member is made of a steel plate on which a positioning projection that fits into the joint portion is formed, and the metal plate is made of a zinc iron plate foil having a thickness of about 60 microns.

[0022]

As is apparent from the above description, according to the present invention, a thin metal plate is attached to a face material so that the flame shielding effect is particularly enhanced. It is possible to easily and inexpensively improve the fire resistance of the face material without overlapping the layers and making the thickness sufficiently thick. In addition, depending on the position where the metal plate is attached, it is possible to prevent the face material, whose strength has deteriorated due to fire heating, from falling off. The performance can be further improved. Moreover, since the metal plates of adjacent face materials are integrally connected through the joint material having fire resistance, it is possible to reliably prevent the intrusion of flame from the joint portion of the face material. With this, the reliability of the fire resistance performance can be increased.

Further, since the joint material is formed with a positioning protrusion, the joint material can be easily positioned on the joint portion only by fitting the joint material along the joint portion. It is possible to improve workability. Furthermore, by constructing the metal plate from a zinc iron plate foil having a thickness of about 60 μm, the metal plate can be easily cut and processed, and the workability can be improved.
