Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor insulation method and a floor for a building which can effectively prevent heat leakage from a floor joist and is particularly effective for a steel house in which the floor joist is formed of metal. Related to heat insulation structure.

[0002]

2. Description of the Related Art Conventionally, as a floor heat insulating structure of a building, as shown in FIG.
It is known that there is a space between the floor and the floor, and heat insulation between the floor and the floor.

[0003]

However, in the conventional structure described above, since the floor joist 1 is exposed,
There is a problem that the floor joist 1 itself forms a thermal bridge and lowers the heat insulation performance. In particular, when a metal floor joist is used, it becomes a large thermal bridge, and even if a high-performance heat insulating material 2 is constructed, the heat insulation of the entire floor is low.

As another problem, it is necessary to attach a holder for holding the heat insulating material to the floor joist 1 in order to construct the heat insulating material 2. Conventionally, the mounting of the receiver is performed using a drill screw or an adhesive. . Therefore, especially in the case of the metal floor joist 1, the workability is poor and it takes time.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a floor insulation method and a floor insulation structure which can reduce the number of thermal bridges caused by the conventional exposure of floor joists, improve the heat insulation performance of the entire floor, and are easy to construct. The purpose is to do.

In order to achieve the above object, a floor insulation method according to the present invention suspends a support made of a material such as plastic which is difficult to conduct heat on each floor joist of a building, and inserts a heat insulating material between the supports. By laying the floor, heat leakage from floor joists was prevented.

In addition, the floor heat insulating structure according to the present invention comprises a receiving member made of a material such as plastic suspended on a floor joist of a building, which is difficult to conduct heat, and a heat insulating material spread between the receiving members. A floor heat insulation structure was configured.

[0008] With this configuration, the floor joist does not become a thermal bridge, so that the heat insulation effect of the entire floor can be enhanced. In addition, a simple construction method in which a heat insulating material is spread between the receiving members is provided. Anyone can carry out easily and quickly without skill.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 are perspective views for explaining the procedure of the floor insulation method according to the present invention. In FIG.
The floor joist 1 is made of C-shaped steel, has ribs 3 extending horizontally at upper and lower ends, and forms a folded portion 3a at the tip of the rib 3.

On the other hand, the receiving member 4 is made of plastic having a low thermal conductivity in consideration of heat insulation. Specifically, polypropylene, polyvinyl chloride, or the like, which has a low thermal conductivity and is unlikely to become a thermal bridge, is preferable, but other inorganic materials, wood, paper, metal, or a composite material thereof can also be used.

The length 1 of the receiving member 4 is not particularly limited, and may be any range as long as it can be handled. The height h is determined according to the thickness of the heat insulating material.
It is desirable that the dimensions be such that there is no gap between the lower part. By creating a plurality of heat insulator receivers 4 having different heights h, heat insulators 2 having different thicknesses can be installed without limitation.

As shown in FIG. 3 (a), the receiving member 4 is provided with a hook 5 for hanging the folded portion 3a of the floor joist 1 and a supporting wing 6 for supporting the heat insulating material 2. .
As shown in FIGS. 3B and 3C, a receiver 4 provided with only one support wing 6 can be used for a floor joist such as an edge portion of a building.

The heat insulating material 2 is preferably a glass wool board, but is not limited thereto, and any board-shaped heat insulating material such as an inorganic fiber material such as rock wool or an organic polymer material such as polyurethane foam or polystyrene foam. ,
Anything can be used.

In order to install the heat insulating material 2, first,
Is suspended on the folded portion 3a of the floor joist 1. Next, as shown in FIG. 2, the heat insulating material 2 is placed on the heat insulating material receiving member 4 while sliding. In this way, the heat insulating material 2 is laid all over the floor joist 1.

FIGS. 4A to 4C are perspective views showing another embodiment. In this embodiment, a U-shaped steel material is used as the floor joist 1 and only the rib 3 has no folded portion. Therefore, the hook 5 of the receiving member 4 made of a heat insulating material is doubled so that the rib 3 of the floor joist 1 can be sandwiched. FIG.
The application of the receiving member 4 provided with only one of the support wings 6 (b) and (c) is the same as the application of FIGS. 3B and 3C.

FIGS. 5A to 5C are perspective views showing another embodiment. In this embodiment, a U-shaped steel material is used as the floor joist 1 as in FIG. 4, while only one hook 5 is used as the receiving member 4. In this case, it becomes very easy to suspend the heat insulating material receiver 4 on the floor joist 1. Further, after the heat insulating material 2 is spread over the entire surface, the heat insulating material 2 itself serves as a stopper, so that the heat insulating material receiver 4 does not fall. Note that the support wing 6 shown in FIGS. 5B and 5C is used.
3 (b), (c)
It is the same as the application.

FIGS. 6A to 6C are perspective views showing an example in which the present invention is applied to an insulated floor structure of a conventional wooden building or a two-by-four house. In this embodiment, wood is used as the floor joist 1, and the floor joist 1 has no rib 3. In this case, the heat insulator receiver 4 can be easily attached with nails or screws. 6 (b) and FIG. 3 (c), the support 4 provided with only one support wing 6 is used in FIG.
This is the same as the use of (c).

In the above embodiment, the receiving member 4
Is attached to the entire floor joist 1, but the portion where the heat insulating material 2 does not fall may be discontinuously suspended. However, in this case, care must be taken so that no gap is formed between the heat insulating materials 2.

[0019]

As described above, according to the floor heat insulation method of the present invention, a support made of a material that is difficult to conduct heat to each floor joist of a building is suspended, and a heat insulating material is provided between these supports. Because of the spread, heat leakage from floor joists can be prevented. If a plastic having a low thermal conductivity is used as the receiving member, a higher heat insulating effect can be obtained. Furthermore, since the floor heat insulation method of the present invention is a simple construction method in which a heat insulating material is just spread between the receiving members, anyone can easily and quickly carry out the method without any skill.

Further, according to the floor heat insulating structure of the present invention, the heat insulating material is made of a material suspended on each floor joist of the building and made of a material that is difficult to conduct heat, and a heat insulating material spread between these materials. In addition, the floor joist 1 is covered with a heat insulating material, and a high heat insulating effect can be exhibited as a whole floor without forming a thermal bridge.
