DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides easy construction, low material loss, and a small gap between a heat insulating material and a pillar.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly airtight synthetic resin foam heat insulating material for a house and a method for constructing the heat insulating material.

[0002]

2. Description of the Related Art Conventionally, as a heat insulating material made of a synthetic resin foam filled between a pillar, a stud, a joist, or a rafter between walls, floors, and roofs in contact with the outside of a house. In order to insulate and insulate a rectangular space between a pillar and a stud, a joist, and a rafter, a heat insulating material made of a rectangular flat synthetic resin foam is used.

[0003]

However, such a heat insulating material made of a rectangular flat synthetic resin foam has a design in which the distance between columns and studs, between joists and joists, or between rafters and rafters is designed. Since it is not always constant at the stage or at the stage of construction, the heat insulating material has to be prepared larger than the above-mentioned interval, and a part of the heat insulating material has to be cut out and fitted. In addition, the amount of heat insulating material cut off at this time also increased, so that the amount of dust also increased. However, since it is necessary to measure the length of the rectangular space between pillars and studs, between joists, and between rafters before fitting heat insulating material in this way, the measurement work is also difficult. This is labor, and the cut portion is too large to create a gap. On the other hand,
Since it is a great effort to perform the cutting work, slits are provided in advance from the front and back sides of the heat insulating material made of a rectangular plate-shaped synthetic resin foam to have elasticity, and this is taken from both ends. The construction method of compressing and fitting was performed. However, such a slit portion of the heat insulating material has a drawback that the heat insulating performance of the heat insulating material is impaired, and even the heat insulating material having such a slit portion cannot eliminate the cutting operation.

[0004]

Means for Solving the Problems The present inventor has conducted intensive studies in view of the above problems, and as a result, made the shape of the heat insulating material a specific shape, and combined the heat insulating materials to reduce the width of the heat insulating material.

That is, the synthetic resin foam heat insulating material of the present invention is characterized in that, in the synthetic resin foam heat insulating material, the shape of the heat insulating material is a substantially right triangle having a flat plate shape. In addition, the construction method of the synthetic resin foam heat insulating material according to another invention of the present invention is a method for manufacturing a wall, a floor, and a roof in contact with the outside of a house, between columns and studs, between joists and joists, or rafters. In the method of installing a synthetic resin foam heat insulating material for filling a synthetic resin foam heat insulating material between a rafter and a rafter to insulate a house, the method comprises the steps of: The first synthetic resin foam insulation material of a substantially right triangle having a flat plate shape between the trees is abutted to the long side of the pillar, stud, joist, or rafter, and the short side is the floor side or the joist side or After placing it in contact with the eaves side,
