Description

[Detailed explanation of the invention] This invention uses a hard insulating material as a core material on the upper surface of the large drawer,
This invention relates to a heat insulating floor structure which eliminates the need for joists and has a high heat insulating effect, by directly placing and fixing floor panels covered with surface materials such as plywood on both surfaces of the floor panels.

Conventional insulated floor structures are constructed by installing joists B on the top surface of joists A and installing heat insulating material C between the joists BB, which requires time and effort to install joists B and heat insulating material C. A, joist b portion forms a cold bridge and reduces the insulation effect, and gaps are created between joist b, large drawer a, and insulation material c, impairing the insulation effect, which is a problem with the insulation floor structure. It was listed as.

Furthermore, the installation of the heat insulating material c requires a lot of effort, such as having to stretch a wire for installing the heat insulating material c under the joist b, and a solution to this problem has also been desired.

The great idea was to solve these problems in the past, and it consisted of a floor panel made of hard insulating material as a core material and covered with plywood or other surface material on both sides. The purpose of the present invention was achieved by directly mounting and fixing.

To further explain the details of the present invention based on the illustrated embodiment, Fig. 3 is a vertical cross-section outlining the contents of the present invention, and the inside is made of a plate-shaped hard heat insulating material with a compressive strength of 0.5 kg/cm ² or more. Material 1 For example, synthetic resin foam,
A heat insulating floor constructed by directly placing and fixing a floor panel 3 on the upper surface of a drawer 4 with a soft fiberboard or the like inside and a surface board 2 made of plywood, epoxy board, etc. on both surfaces to form a floor surface. Show the structure. In this heat insulating floor structure, the floor panel 3 with the hard heat insulating material 1 inside is fixed to the upper surface of the main drawer 4, so that the floor panel 3 has sufficient support strength against the load that is generally applied to the upper surface of the floor. In addition, since it is laid over the entire upper surface of the main 4, unlike when insulation material was installed between the joists, gaps may occur between the joists and the insulation material, which may deteriorate the insulation effect, or the joists may It constitutes a cold bridge, which reduces the insulation effect and eliminates the problem. Also, when installing joists and insulation material 1 on the main drawer 4 to create an insulated floor structure,
The present invention does not require any joists, and the floor panel 3 can be placed and fixed directly on the upper surface of the drawer 4, so the construction is simple and economical.

FIG. 4 shows another embodiment of the floor panel 3, in which the surface material 2 on one side is made into a mutually ladle structure 5 at the ends where the panels meet, thereby blocking ventilation between the underfloor and the room. The purpose is to increase the heat insulation effect.

5 and 6 show a structure in which a stretched structure 6 is employed at the mating ends of the floor panels 4 in order to enhance the gap blocking effect and to increase the support strength against loads from above.

As shown in FIG. 5, the construction structure 6 includes a frame body 7 having an L-shaped cross section facing each other in the heat insulating material 1 under the surface plate 2 at the mating ends of the floor panel 3. By setting and matching the floor panels 3,
A groove 8 between opposing surfaces of the L-shaped frame body 7 is provided with a groove 9.
It can be inserted as is or with an adhesive.

Thus, as shown in FIG. 6, by placing and fixing the floor panel 3 to which the bulge structure 6 is applied on the daihiki 4, the mating ends of the floor panel 3 are sealed with the rug 6. Therefore, it is possible to prevent the occurrence of gaps and ventilation at the ends where the floor panels 3 butt or contact with the joists as in the past.
The timbers 9 installed so as to be constructed between them also serve as a core material in place of a joist, and improve the support strength of the floor panel 3.

As described above, in the insulated floor structure according to the present invention, the floor panel 3 consisting of the hard insulation material 1 and the surface material 2 is directly constructed on the upper surface of the main drawer 4 so as to have the supporting strength as a floor, so no joists are required. This simplifies construction, and since there are extremely few areas without insulation material 1, cold bridges do not occur.In addition, because the butt structure and each unit panel are manufactured in a factory, there is no need to worry about the butt ends, that is, between the joints. Gaps are less likely to occur, and this effect can be expected to be further improved by making the joints have a joint structure or a concrete structure.
