[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-resistant wall structure using a heat-insulating board, and easily fixes a heat-insulating board in which a structural material is laminated on a heat-insulating material of a soft material such as a synthetic resin foam from the heat-insulating material side. This is particularly suitable for mounting a heat insulating board in an external heat insulating method.

[0002]

2. Description of the Related Art In a building such as a house, a heat insulating material is used to keep a room comfortable. However, in order to prevent decay and rust due to dew condensation, a wooden or steel building structure is used. While the external insulation method of attaching insulation to the outdoor side (outdoor side) of the building is becoming popular, social demands for improving the seismic resistance of buildings are increasing, and the structural panel is installed on the outdoor side of the frame to withstand the strength. It has been practiced to mount a heat insulating material on the structural face material constituting the load-bearing wall as a wall.

[0003] In order to eliminate the trouble of separately mounting the structural face material and the heat insulating material, for example, a heat insulating board 1 as shown in FIG. 3 is used. Are laminated and integrated by bonding them in advance with an adhesive layer 4 or the like.

As shown in FIG. 1, such a heat insulating board 1 is attached to the heat insulating material of the structural face material 2 at a portion corresponding to the mounting position of the heat insulating board 1 to the frame (building structural material). 3 is formed without molding, or is cut after molding to remove the heat insulating material 3, and the structural side material 2 side of the heat insulating board 1 is placed on the outdoor side A of a frame such as a pillar 5 or a stud 6. Then, the structural face material 2 in a portion without the heat insulating material 3 is fixed to a building structural material which is a shaft set such as the pillar 5 or the stud 6 with a short nail 7. Then, a body edge 8 higher than the thickness of the heat insulating material 3 is attached to a portion of the connection portion of the heat insulating board 1 from which the heat insulating material 3 has been removed, or a heat insulating material having the same dimensions as the heat insulating material 3 removed. After preparing and attaching with metal fittings, the body edge is further attached with metal fittings.
The exterior material 9 is located through the “0”. In addition,
In the figure, reference numeral 11 denotes an interior material attached to a shaft set such as the pillar 5 and the stud 6 on the indoor side B.

In this heat insulating board 21, the heat insulating material 2
3, a sheet of paper, synthetic resin, or the like is stuck as a face material 23a.

When such a heat insulating board 21 is attached to a pillar 5 or a stud 6 which is a building structural material to form a heat-resistant wall structure, the structural face material 22 of the heat insulating board 21 is used for the pillar 5 or the stud 6. The screw 30 is tightened from the outdoor side A of the heat insulating material 23 with the electric tool 31 while being in close contact with the outside A.

Then, after the screw 30 rotated at a high speed breaks the face material 23a of the heat insulating material 23 at the tip of the screw portion 32,
The threaded portion 32 advances while cutting through the cut-out portion of the heat-insulating material 23, and the screw head 33 moves to the outdoor side A of the structural face material 22 of the heat-insulating board 21.
Is directly adhered to the surface without interposing a small piece of the heat insulating material 23 or the like, and is fixed to the pillar 5 or the stud 6.

By using such a screw 30, the heat insulating material 23 and the adhesive layer 24 are blown off around the screw 30 by the frictional force and the shearing force due to the rotation of the screw 30.
Is pressed against the side surface of the concave portion 34 formed by the forward movement of the screw 30, so that no foreign matter which impairs the load-bearing wall performance is caught between the screw head 33 of the screw 30 and the structural face material 22, and the screw 30 Thus, the structural face material 22 of the heat insulating board 20 can be easily fixed, and the heat insulating board 21 can construct a heat-resistant wall.

If a convex ridge is provided on the lower surface of the screw head 33 of the screw 30, the effect of removing the heat insulating material is enhanced.

Thus, the heat insulating board 21 is
When the heat-insulating wall is constructed by attaching the heat-insulating member, a concave portion 34 corresponding to the size of the screw head 33 of the screw 30 is formed in the heat insulating material 23. This makes it possible to close the air in the concave portion 34 in a closed state, thereby contributing to the heat insulation as a heat-insulating air layer. Insulated performance can be obtained.

An exterior member 26 is attached to the outdoor side A of the rim 25, and an interior member 27 is attached to the indoor side B of the pillar 5 or the stud 6, as in the prior art.

Further, in the heat-resistant wall structure 20 using the heat-insulating board, no special tools or materials are required for mounting the heat-insulating board 21, so that the construction is easy and the construction period can be shortened.

Further, since there is no need to remove the heat insulating material 23 at the mounting portion of the heat insulating board 21, the heat insulating board 21 can be easily manufactured and can be manufactured at low cost.

In the above embodiment, the case where the heat insulating board has an external heat insulating structure has been described. However, the present invention is not limited to this case. Can be applied.

As described above, according to the first embodiment of the present invention, according to the heat-insulating load-bearing wall structure of the heat-insulating board according to the first aspect of the present invention, the heat-insulating board is formed using screws from the heat-insulating material side. Since the surface material is screwed to the building structural material, the heat insulating material is separated by the rotating screw part and the screw head, so that a piece of heat insulating material is inserted between the screw head and the structural surface material. The heat insulation board can be firmly fixed without any intervening member, and a load-bearing wall can be easily constructed, and the heat insulation performance is excellent because there is no cut-off portion of the heat insulation.

Thus, it is not necessary to remove the heat insulating material from the mounting portion of the heat insulating board, and the manufacture of the heat insulating board is easy and inexpensive.

Further, according to the heat-insulating wall structure of the heat-insulating board according to the second aspect of the present invention, since the recess formed in the soft material and separated by the screw is closed by the closing material, the air in the recess is moved. Can be eliminated to form a heat insulating air layer by air, and the heat insulating performance can be further improved.
