DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for efficiently installing a heat-insulating material, such as a soft mat made of non-combustible fibers, on the back side of a base plate attached to a building frame.

[0002]

2. Description of the Related Art Conventional construction methods for attaching a heat insulating material to the back side of a base plate of a roof include, for example, Japanese Utility Model Laid-Open No. 3-991.
As disclosed in Japanese Patent Application Laid-Open Publication No. 18-1994 and Japanese Patent Application Laid-Open No. 4-70441, there is a type in which a heat insulating board is fixed to a rafter with special fittings. However, this construction method is rock wool,
It is difficult to apply a soft mat-like heat insulating material made of glass wool or the like to the back surface of the base plate. This is because fixing the soft heat insulating material only at the rafter portion causes the central portion of the heat insulating material to hang down.

Therefore, as shown in FIG. 4, when attaching the soft heat insulating material 1 to the back surface of the base plate 2, a plurality of nail-shaped fasteners 3 are previously bonded to the back surface of the base plate 2 with an adhesive. After that, a construction method is employed in which the heat insulating material 1 is inserted into each fastener 3 and the stopper 4 is press-fitted and fixed to the tip of each fastener 3.

[0004]

However, in the above-mentioned conventional construction method, the work of bonding a large number of fasteners 3 to the back surface of the base plate 2 with an adhesive is extremely troublesome, and the adhesive is dried. Until the work of attaching the heat insulating material 1 must be waited for, the construction efficiency is poor and the construction period is long. Further, when the heat insulating material 1 is inserted into the attachment 3, the heat insulating material 1 is easily inserted in a shifted state, or the heat insulating material 1 is easily loosened partially. There is a drawback that it is impossible to correct it later, and the finished condition of the construction tends to deteriorate.

[0005] The present invention has been made in view of such circumstances, and accordingly, the object thereof is to be able to efficiently attach a soft mat-like heat insulating material to the back surface of a base plate, thereby shortening the construction period and Another object of the present invention is to provide a method of constructing a heat insulating material that can also improve the finishing condition of the construction.

[0006]

According to a first aspect of the present invention, there is provided a method for constructing a heat insulating material, comprising the steps of: providing a base plate having a back surface to which a cloth is bonded via an elastic bonding layer in advance; Then, a soft heat insulating material made of incombustible fiber is applied to the cloth on the back surface of the base plate, a nail having a hook at the tip is pierced into the heat insulating material, and the hook at the tip of the nail is inserted into the cloth. The heat insulating material is attached to the back side of the base plate by piercing and engaging with the base plate.

In this construction method, there is no need to previously bond the nail to the back surface of the base plate, and the construction can be performed by merely applying the nail material to the back surface side of the base plate and piercing the nail at an arbitrary portion of the heat insulation material. Installation of thermal insulation is extremely simple. In addition, it is possible to adjust the position of the heat insulating material freely before nailing the heat insulating material addressed to the back side of the base plate, and at the same time, select the slack part of the heat insulating material during the construction. The nail can be pierced there and engaged, and the construction can be performed with a good finish without displacement or looseness of the heat insulating material.

According to a second aspect of the present invention, an adhesive is applied to the entire surface or a part of the cloth on the back surface of the base plate, and the heat insulating material is adhered to the cloth with the adhesive. Can be attached firmly.

According to a third aspect of the present invention, the non-combustible fibers constituting the heat insulating material are inorganic fibers such as slag wool, rock wool, glass wool, and ceramic wool. Thereby, heat insulation and fire resistance are improved.
