Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sandwich panel in which a wood board is attached to the front and back of a heat insulating board made of hard urethane foam or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, flooring of a wooden house is provided with joists 3 at predetermined intervals on the upper surface of a base 2 fixed to the upper surface of a concrete foundation 1, and a single plate on the joists. There is a method of laying a floor plate 4 consisting of and fixing the floor plate 4 to the joist 3 with a nail.

[0003]

However, such a conventional flooring method has a plurality of joists 3 on the base 2.
Are installed at equal intervals, and the floor plate is nailed and fixed on it, so there are many execution steps and the construction period is long and the cost is high.Because only one plate is used, heat insulation, airtightness, durability There was a problem such as lacking in. An object of the present invention is to solve these problems and to provide a sandwich panel which is excellent in heat insulating property, airtightness, durability and does not generate squeak noise.

[0004]

In order to achieve the above object, the sandwich panel of the present invention has a stepped portion formed on an end surface of a heat insulating plate made of a hard urethane foam material and the like, and a wood material is formed on the front surface and the back surface of the heat insulating plate, respectively. The board is attached.

[0005]

The sandwich panel of the present invention having the above-mentioned structure is directly installed on the base. Then, the steps of the end faces of the sandwich panels adjacent to each other are fitted to each other, and the seam is adhered with an airtight adhesive tape or the like.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1-3 show a sandwich panel 10 according to one embodiment of the present invention. The sandwich panel 10 is made by attaching wood plates 13 and 14 to the front and back of a heat insulating plate 11. The heat insulating plate 11 is a rectangular flat plate made of a hard urethane foam material, etc. Are formed.

For example, in this embodiment, as shown in FIGS. 1 to 3, on the rear and right end surfaces of the front and rear left and right end surfaces, the upper half of the heat insulating plate 11 has a step portion 12a having a shape protruding laterally by the same width,
12b, the lower half of the heat insulating plate 11 on the front side and the left side is step portions 12c and 12d having a shape protruding laterally by the same width as the front step portions 12a and 12b. A wood plate 13 is attached to the front surface of the heat insulating plate 11, and a wood plate 14 is attached to the back surface of the heat insulating plate 11.

Since the sandwich panel 10 of the present invention has such a structure, a plurality of sandwich panels 10 of the present invention are arranged on the upper surface of the base 2 fixed to the upper surface of the concrete foundation 1 as shown in FIG. The upper protruding step and the lower protruding step of the adjacent sandwich panels 10 are fitted to and brought into close contact with each other, and the step portions are sequentially fitted to each other in the order of front, rear, left and right. Then, the airtight pressure-sensitive adhesive tape 15 is attached to the seams of the sandwich panels 10 and 10 adjacent to each other from the upper surface or both upper and lower surfaces. The sandwich panel 10 is fixed to the base 2 by nailing.

The outermost sandwich panel 10 has no step on the outer end face. In addition, in the above-described embodiment, as shown in FIGS. 2 and 3, the step portions 12a to 12d on both sides of the sandwich panel 10 are opposite to each other on the upper side and the lower side of the protrusion on both sides, but as shown in FIG. The sandwich panel 10 adjacent to the sandwich panel 10 may be turned upside down and the step portions may be fitted together. Alternatively, as shown in FIG. 6, one end of the heat insulating plate 11 may have a convex step. The portion 15a is provided, and the concave step portion 15b is provided at the other end so that the adjacent sandwich panel can be provided with the concave step portion 15b.
Alternatively, the convex step portion 15a may be fitted.

The step portion may be provided on only one side of the sandwich panel 10, two sides, three sides, or four sides. In the above description, the sandwich panel 10 of the present invention is used.
Although the case of using as a floor material is illustrated, the sandwich panel 10 of the present invention may be used as a wall, a ceiling, or the like.

[0011]

As described above, the sandwich panel of the present invention has a structure in which a step portion is formed on the end face of a heat insulating plate made of a rigid foamed urethane material, and wood plates are attached to the front and back surfaces of the heat insulating plate. So, by fitting the steps of adjacent sandwich panels, the floor of the house,
When used for ceilings, etc., it will be a comfortable house with excellent heat insulation, airtightness, and durability.

Especially when it is used for floors, a wooden board is stretched on both sides of a rigid foamed urethane material so that airtightness and heat insulation are extremely enhanced, and moisture from under the floor is completely cut off, so that comfortable living is possible. The environment is obtained.

Further, since the present invention is a sandwich panel in which a wooden board is stretched on both sides with a rigid foamed urethane material in between, it is a panel that is lightweight and has the same strength as a thick single plate, so that it can be used on the floor. When you use it, you don't need joists,
It can be installed directly on the base. Therefore, since the sandwich panel which has been improved and produced is used for the floor, the construction time is short and the construction cost is low.
