Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure, a heat insulating material receiving member, and a building unit.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 8-144474.
As described in the publication, a plurality of floor beams are provided between substantially parallel floor girders as a floor structure of a box-shaped building unit used for a unit building. There is known a floor structure in which a plurality of floor joists are provided substantially orthogonally on a beam, and floor boards are stretched on the floor joists.

In such a floor structure, in order to provide heat insulation performance, Japanese Patent Laid-Open Publication No. Hei 8-144474 discloses a method in which a floor base sheet is stretched over the lower surfaces of a plurality of floor joists, and the lower surface of the floor plate is connected to the lower surface. The space formed by the floor joists and the floor base sheet is filled with a heat insulating material.

[0004]

However, in such a conventional floor structure of a building unit, in order to construct a heat insulating material, an underfloor sheet as a receiving material of the heat insulating material is attached in advance. However, there is a problem that the number of man-hours increases accordingly.

[0005] Therefore, it is considered that the man-hour for mounting the receiving material can be omitted by using a structure in which the heat insulating material and the receiving material are integrated. If it is manufactured by integral molding, there is a problem that it is not practical because the cost of the mold is high.

[0006] The insulation performance required in a house differs depending on the area where the house is installed, and architectural heat insulating materials having different thicknesses are used depending on the area. In addition, the thickness of the heat insulating material used for building differs depending on the type of house, such as a reinforced concrete house and a wooden house.

In the newly adopted new energy conservation standard, Japan is divided into six regions from extremely cold regions to warm regions, and the thickness of the heat insulating material, which is the standard for the roof or ceiling, walls and floors, is defined. ing. For example, in the case of a wooden airtight house floor, the difference in the thermal resistance value of the heat insulator between the Hokkaido area (I area) and the Shikoku, China, and Kyushu areas (IV area) is required to be up to about 9 times. When the heat insulating material is made of synthetic resin foam, in the IV region and the I region,
The thickness is a difference of 7 to 9 times.

[0008] In view of the above-mentioned circumstances, when a required heat insulation construction is performed by using a synthetic heat insulation material made of synthetic resin foam suitable for a house in each region, many types of architectural materials having different thicknesses are required. It is necessary to prepare insulation. Therefore, it is necessary to manufacture other types of molds, which leads to an increase in cost. Further, for example, in the case of manufacturing a heat insulating material for buildings by bead foam molding, when the wall thickness is large, the production efficiency of the foam tends to be extremely poor, and the one having a thickness of about 200 mm is in the Hokkaido region (region I). However, it is not easy to produce it efficiently.

It is an object of the present invention to provide a floor structure, a heat insulating material receiving member, and a building unit which can solve the above-mentioned problems and can be easily and inexpensively implemented. is there.
