Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall insulation structure for buildings.

[0002]

2. Description of the Related Art A conventional heat insulating structure for a wall has a heat insulating material (2) arranged outside a wall body (1) as shown in FIG.
The furring strip (3) is brought into contact with the outside of (2), and fasteners (4) such as nails and screws are driven from the furring strip (3) through the heat insulating material (2) to the wall frame (1). An outer wall material (6) is stretched on the outside of the furring strip (3) through a mounting bracket (5).

[0003]

As the heat insulating material (2) used in the heat insulating structure, a plastic foam such as polystyrene foam or a glass fiber board is used, but it is a porous body. The internal structure strength is small,
When the external shearing force indicated by arrow a is exerted on the outside, the nail (4)
The larger moment is applied to the head of the and the holding force is reduced as a result of the nail being twisted. If the heat insulating material is thickened to increase the heat insulating effect, the nail (4) becomes longer, the moment acting on the head becomes larger, and the twisting of the nail becomes remarkable. If a gap for inserting the furring strip is provided in the heat insulating material, and if the furring strip is inserted in the gap and directly fixed to the wall body with a nail, the nail becomes shorter and the moment applied to the nail head can be reduced. In this case, the gap of the heat insulating material becomes a heat insulating defect portion, and the heat insulating effect is deteriorated.

[0004]

As a means for solving the above-mentioned conventional problems, the present invention provides a through hole (13) at a predetermined portion of a heat insulating material (12), and the through hole (13) is hard. A plug body (14, 24) made of a material and having a height greater than the thickness of the heat insulation material (12) is fitted, and the heat insulation material (12) is attached to the wall frame (at the position of the plug body (14, 24). Fasten using the fastener (18) to 1),
The outer wall member (6) is attached to the outer end surface of the outer wall member (6) by attaching a mounting bracket (19) of the outer wall member (6) and fixing the end of the outer wall member (6) to the mounting bracket (19). It provides a heat insulating structure for the wall stretched outside the material (12). The through hole (13) is preferably cylindrical, and the plug body (14, 24) is preferably a truncated cone shape in which the minimum diameter is set substantially equal to the diameter of the through hole (13). The material (12) is preferably a foamed plastic plate.

[0005]

[Function] The plugs (14, 24) are fitted into the through holes (13) of the heat insulating material (12). If the through hole is cylindrical and the plug has a truncated cone shape with a minimum diameter set substantially equal to the diameter of the through hole,
The plugs (14, 24) are tightly fitted in the through holes (13), and the gap between the through holes (13) and the plugs (14, 24) does not impair the heat insulating property.

The heat insulating material (12) is fixed to the wall body (1) at the location of the plugs (14, 24) by using fasteners (18) such as nails. Since the stoppers (14, 24) are made of a hard material and hold the fastener (18), even if a shearing external force is applied to the head of the fastener (18), the fastener (18) The twist is prevented. The stopper (14,
Since the height of 24) is larger than the thickness of the heat insulating material (12), the plugs (14, 24) project beyond the outer surface of the heat insulating material (12).
Therefore, the outer wall member (6) is fixed to the outer end surface of the plug body (14, 24) through the fitting (19) without attaching the furring strip.
