Description

[Detailed description of the invention] This invention involves laminating and pasting a synthetic resin foam (hereinafter simply referred to as foam) of an appropriate thickness on the back side of plywood such as plywood, and placing it at an appropriate position, for example, in the center. For example, a dovetail groove that fits into the frame (truck rim, rafter) is formed, and the side surface and back surface (back surface) for forming the dovetail groove of the form including the dovetail groove are covered with a waterproof sheet, and the waterproof sheet This invention relates to a base plate with a heat insulating material (hereinafter simply referred to as a base plate) whose back surface (rear surface) is formed of aluminum foil.

In particular, its purpose is to create a dovetail structure in the form of the gap formed between the frame and the base plate when the hard part of the base plate comes into contact with the frame when the base plate is installed on the frame of a roof or external wall. This method not only improves insulation by using the dovetail grooves as a guide, but also makes it easier to install the base plate by using the smooth surface of the aluminum foil to guide it and the foam's excellent cushioning properties. .

Generally, in order to improve the insulation properties of roofs and exterior walls, it was common to construct a base plate made of plywood and insulation boards laminated together on top of the structure, and then construct roofing materials and exterior wall materials on top of that. .

When using such a base board, although it is easy to install, it has the disadvantage that the heat insulating board is partially compressed by snow accumulation in winter, creating unevenness on the base and breaking the connection of roofing materials, etc. .

Furthermore, as a base plate that eliminates this drawback, there is also known a base plate that is cut out in advance at the position where the heat insulating plate contacts the building frame, so that the plywood and the rafters etc. come into direct contact.

However, in this case, the width of the notch groove is usually set to a width that can absorb manufacturing errors during the manufacturing of the frame.
Therefore, it is technically impossible to prevent the difference between the width of the notch groove and the width of the frame of the rafters, etc., and because the dimensions change over time, it will gradually occur even if there is no gap during construction. It was common to do so.

As a result, large gaps will be created between the side walls of the rafters and trunk edges and the fitting groove side walls, which will not only significantly reduce the insulation properties of the base as a whole, but also cause fog to form and the base to deteriorate. It had the disadvantage of corrosion.

Further, although the foam has cushioning properties, it is brittle and easily breaks if it is forcefully inserted between the frames.

- In order to eliminate these drawbacks, the present invention forms a dovetail groove with an opening narrower than the width of the frame so that it reaches from the back side of the foam to the back side of the plywood, and also utilizes the cushioning properties of the foam. There is no gap formed between the dovetail grooves of the rafters and the foam, which is improved by the synergistic effect of the insulation between the rafters and the rafters, the insulation of the foam, the thermal radiation of aluminum, and the airtightness between the rafters. It can significantly improve the corrosion of the base due to condensation, soundproofing, and moisture proofing, and when installing the baseboard on the frame, it has a synergistic effect of waterproofing, guiding to the frame due to the ease of sliding on the sheet surface, and cushioning properties of the foam. To provide a base board that is easy to install without damaging the form.

Hereinafter, an embodiment in which the base plate according to the present invention is used for a roof will be described in detail with reference to the drawings.

1 is a plywood board made of a commercially available rectangular plywood board with a thickness of 7 to 12 TIrIrL1 and a size of 900 x 180 mm.

2 is a dovetail groove 3 which has a foam and has cushioning properties, and is used to insert rafters, etc., which will be described later, at appropriate positions on the back side of the plywood 1.
It is pasted to form a .

For adhesion of the foam 2, the laminated body can be adhered to the back side of the plywood 1 through an adhesive, or the waterproof sheet and plywood 1 described later can be attached.
In between, the foam raw material is discharged, reacted and foamed in the mold, and cured, and the self-adhesive property generated during the reaction is used to form a base plate that integrates the plywood 1 and the waterproof sheet. This method is used.

A specific example of the foam 2 is one of polystyrene foam, polyurethane foam, polyisocyanurate foam, and phenol foam, and its thickness is about 10 to 1001.

It should be noted that the plywood 1 and the form 2' are formed in the same large square increments.

3 is a dovetail groove, and when the form 2 is attached to the back side of the plywood 1, a cross section with an opening narrower than the width of the frame is placed in the center of the form 2 or at an appropriate position parallel to the side edge of the plywood 1. The cutout portion or □ is a portion of form 2 that does not exist.

In particular, the dovetail groove 3 forms a cross section that widens from the opening toward the back surface of the plywood 1, which is 11>1□ when the opening width on the back surface (rear surface) is 1□ and the width of the bottom surface of the opening is 1□. In addition, the above-mentioned 11 is equivalent to or somewhat larger than the width of the rafters or the rim.

Also, 1112=2Δ1, and Δl is 2~sTrgI&
The width difference Δ1 is the expansion/contraction width of the form 2 for closing the gap between the rafter and the dovetail groove 3, which will be described later.

4 is a waterproof sheet that is made by laminating aluminum foil with a smooth surface and other sheet-like materials, and is mainly used for heat radiation, protection of foam 2, and when attaching a base plate to a building frame, etc. It functions as a sliding material and a mold release material.

This waterproof sheet 4 is made by fixing the back surface of the foam 2 and the side surface forming the dovetail groove 3 together with an adhesive or using the self-adhesive property at the time of forming the foam as described above, and fixing the above-mentioned portions of the foam 2 together. It is something to cover.

In addition, the fourth waterproof sheet structure is made of aluminum foil laminated with one or more sheet materials such as asbestos paper, kraft paper, lead foil, asphalt felt, and synthetic resin sheets, and has a certain degree of rigidity. It is.

Next, a construction example will be explained.

Assume that the base plate shown in FIG. 1 is to be constructed as shown in FIG. 2.

When the dovetail groove 3 is inserted onto the rafter A having a width of W, the structure shown in FIG. 2 is obtained.

In this case, dimensionally W>12 and Δ of form 2
It is compressed by rafter A by 1.

Therefore, the elasticity of the form 2 acts on the rafter A by an amount of Δ1, and no gap is created between the rafter A and the dovetail groove 3, so that the heat insulation property does not deteriorate.

Further, during construction, the surface of the waterproof sheet was easily slippery due to the aluminum foil, so construction was quick and the form 2 at the end of the dovetail groove 3 was not damaged.

What has been described above is only one embodiment of the present invention, and inorganic foamed particles can also be dispersed in the foam 2.

As mentioned above, according to the base plate with heat insulating material according to the present invention,
■Since the outer surface of the foam is covered with a tarpaulin sheet, the foam will not be damaged during construction, and the tarpaulin sheet is easy to slip.1. Easy to construct.

■The insulation properties of the foam and the heat reflection of the waterproof sheet further improve the insulation properties.

□■A waterproof sheet is made by integrally forming aluminum foil and other sheet-like materials, and is used as a backing material for the base plate to provide strength and strength.
It has sufficient heat radiation properties, eliminating the need for separate construction of interior materials in factories and buildings.

■The opening of the dovetail groove is made smaller than the width of the rafters and the rim, and the gap between the side of the dovetail groove and the side of the rafter and rim is sealed with the opening of the dovetail groove, thereby preventing heat leakage between the rafters and the rim. This can be largely prevented and insulation properties can be greatly improved.

It has the following characteristics.
