Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a roof of a building, a roof,
The present invention relates to a heat insulation panel used for walls, floors, etc.

[0002]

2. Description of the Related Art Conventional heat insulating boards used for walls, floors, roofs, etc. of buildings are made of synthetic resin foam such as rigid polyurethane foam as a core material. Pillars assembled at appropriate intervals on site,
A method is used in which the heat insulating board is temporarily fixed to the studs, rafters, Daihiki, joists and the like with nails and the interior materials and exterior materials are nailed. However, with this method, it is necessary to measure and cut the heat insulation board to be installed in the framework according to the shape of the installation position during construction,
It took a lot of work. In addition, there are many unnecessary parts due to cutting, waste of material is large, and since the measurement and cutting are done manually, there is a possibility that the size of the heat insulation board and the frame does not match and there is a gap, which lowers the heat insulation. It was

At the work site, there is also adopted a method in which a plywood is installed on the shaft assembly, an appropriate number of furring strips are provided further outside the shaft working, and the heat insulating stock solution is sprayed between the furring strips. In this method, there is a risk that the heat insulating material undiluted solution may be scattered around at the time of spraying, and the work cannot be performed unless the entire building except the sprayed portion is covered with a sheet or the like, which is very troublesome.

Furthermore, a panel with a frame which is formed in advance according to the shape of a predetermined position, such as between columns of a building, between beams or between beams and rafters, is also used. However, even in this method, the framed panel is fitted at a predetermined position of the building at the time of construction, and then the heat insulating board is measured and cut according to the shape of the framed panel and bonded to the inside of the frame. There are many cases, and it is difficult to accurately bond the heat insulating board in the frame because the measurement and cutting are done manually.
This caused a gap, resulting in inferior heat insulation and a cause of a decrease in work efficiency.

The pier 5 may have the same thickness as the frame 3 or may have a thickness smaller than that. Providing the pier 5 increases the strength of the heat insulation panel 1, and can favorably prevent warping, twisting, and the like. Particularly in the case of a long heat insulation panel 1, by appropriately arranging a plurality of the heat insulation panels 1, Strength can also be increased.

The heat insulating material 4 is formed by injecting a hard synthetic resin into the upper opening space formed by the flat plate 2 and the frame 3 so as to cover the flat plate 2 and foaming and solidifying it. here,

There is also a method of making it. According to these methods,
The heat insulating material 4 in close contact with the flat plate 2 and the frame 3 in the upper opening space composed of the flat plate 2 and the frame 3 can be easily filled.

The heat-insulating panel 1 is installed between columns such as columns, studs, rafters, Daihiki, joists, etc. constructed at a construction site.

For example, as shown in FIG. 6, three heat insulating panels 1a, 1a ', 1a "formed in a triangular shape or a trapezoidal shape are fitted to a beam and a rafter, or at a predetermined position such as between studs. On the wall surface, a rectangular heat insulating panel 1b formed vertically long with respect to the vertical direction of the building is fitted to the side portion of the window on the wall surface. The upper part is configured by fitting a single heat insulating panel 1b 'formed in a rectangular shape that is horizontally long with respect to the vertical direction of the building. In addition, the roof, floor, and the like can also be configured by a combination of one or a plurality of heat insulating panels 1.

Since these heat insulation panels 1 are accurately formed, they can be fitted in close contact with each other without a gap between the shaft sets.

As described above, since the heat insulation panel 1 is accurately formed in advance so as to fit in a predetermined position, it can be fitted at a construction site without processing,
The construction is greatly simplified.

In this embodiment, the method of fitting the heat insulation panel 1 of the present invention into the proper positions between the frameworks of the wooden building has been described, but the frame 3 of the heat insulation panel 1 itself functions as a framework. It is also possible to do so, and it is also possible to stack the heat insulation panel 1 directly on the base to form a building.
In this case, since it is not necessary to construct a framework such as a pillar or a stud, the labor of construction can be saved, and the building can be completed easily in a short time, so that the construction performance is further improved.
