Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating exterior plate mount for fixing a heat insulating exterior plate having a noncombustible material layer surface to a concrete surface.

Conventionally, as a method for attaching a heat insulating exterior plate having a surface of a noncombustible material layer, there is a method for constructing a heat insulating wall body disclosed in, for example, JP-A-55-111546.

In this construction method, a heat insulating exterior board made of glass fiber reinforced cement board and hard foam resin board is fixed to the formwork installed at required intervals using connecting rods, and ready-mixed concrete is placed between the exterior board and the formwork. When constructing a poured heat insulating wall, the part or all of the connecting rod penetrating the heat insulating sheath plate is replaced with a synthetic resin connecting member after the concrete hardens, but the heat insulating sheath plate When a fire occurs outside, even if a noncombustible material layer is formed on the outer surface of the heat insulating exterior board, the part of the noncombustible material surface where the connecting member is attached will be eroded by the flames and the function as a noncombustible material layer will be lost. Problems have been pointed out.

In view of these problems, the present invention devises and improves a fixture for a heat insulating exterior plate having a noncombustible material layer on its surface.

The gist of the present invention is to attach a shaft rod extending from the head to a cone provided on a concrete outer wall, and to create a heat insulating exterior board having a noncombustible material layer surface with the head positioned on the noncombustible material layer surface. Or, for a fixture whose head is positioned within a layer of noncombustible material and fixed to a concrete surface, the fixture is made of metal and has a synthetic resin covering part or all of its surface. The reason lies in the fact that it takes advantage of the

To explain the details of the present invention based on illustrated embodiments, Fig. 1 is a cross-sectional explanatory view of a state in which concrete is poured using a heat insulating exterior plate with a noncombustible material layer surface as a formwork to which the present invention is applied. In the figure, 1 is a heat insulating exterior board, 2 is a non-combustible material layer such as GRC provided on the surface of the heat insulating exterior board, and a separator 3 is set between this heat insulating exterior board 1 and other formwork.
A cone 4 fixed at one end is fixed with a fitting 5, and the heat insulating exterior plate 1 is used as a formwork for pouring concrete, and after pouring is used as the outer surface material of the concrete, At this time, the fixture 5 is the first
As shown in the figure, the head 6 is made relatively large,
A shaft rod 7 extending from the head 6 is screwed into a butterfly hole of the cone 4 to fix the heat insulating exterior plate 1. In this invention, in order to prevent condensation and to prevent the insulation performance of the wall from being impaired, some or all of the
In the illustrated example, the entire exposed surface of the noncombustible material layer 2 is coated with a synthetic resin 8. At this time, when a fire occurs on the outer surface of the heat insulating exterior plate 1, the fire comes into contact with the surface of the noncombustible material layer and at the same time
If the grip fitting 5 is made of synthetic resin as mentioned above (Japanese Unexamined Patent Publication No. 55-111546), this part will melt and the internal insulation board will burn or melt. In some cases, it may become impossible to keep the heat insulating exterior plate fixed on the concrete surface. The present invention was completed by using an outer covering of 8.

Here, the head of the fixture 5 is preferably relatively large in order to firmly fix the heat insulating exterior plate 1 having the surface of the non-combustible material layer 2 as described above. This is to ensure complete fixation at the fixture part even when warpage occurs in the fixture. Moreover, the one shown in FIG. 2A is one in which the entire fixture 5 is coated with a synthetic resin 8. In addition, in Fig. 2B, when the head 6 of the fixture 5 is positioned within the surface of the noncombustible material layer 2 of the heat insulating exterior plate 1, a resin 9 or the like is buried on the surface to bury the head. It is something.

As described above, the heat insulating exterior plate attachment device according to the present invention attaches the shaft rod extending from the head to the cone provided on the concrete outer wall, and attaches the heat insulating exterior plate having the surface of the noncombustible material layer to the head on the surface of the noncombustible material layer. In a fixture that is fixed to a concrete surface by positioning the head part or positioning the head within a layer of noncombustible material, the fixture is made of metal and a part or all of its surface is made of synthetic material. Since the metal is coated with resin, the fire resistance of the fittings is improved, and in the event of a fire, the fittings may melt and damage the non-combustible material layer on the surface of the heat insulating exterior plate. These can be fixed to the wall without compromising their non-combustible properties, and since they are made of metal, their shearing force is strong, increasing the installation strength.Furthermore, the surface of the fixture is coated with synthetic resin. This also makes it possible to prevent condensation.
