Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to insulating floor panels, and more specifically to the underfloor space of houses, as well as exterior and interior wall materials. The insulated floor panel is installed so that air passes through the ventilation space formed between the related.

0002

[Conventional technology]

Conventionally, some flooring materials for houses have been simply floor panels made of plywood etc. It has been adopted. However, conventional floor panels simply made of plywood etc. do not have good insulation. Because of this, especially in the middle of winter when it is cold, rooms that have been warmed by heaters, etc. are placed under the floor. The disadvantage was that it was cooled by the cold air.

0003 In view of this situation, we have developed a thermal insulation system in which a heat insulating material such as glass wool is formed on the floor panel. Floor panels are proposed.

0004

[Problem that the idea aims to solve]

However, conventional insulating floor panels made of the above-mentioned insulating materials such as glass wool Because the roof has insulating properties, heat is transferred between the room and the space under the floor. Although this was suppressed, there were the following drawbacks. i.e. there is generally air flow In some cases, condensation is unlikely to form on the walls, etc., but this conventional insulated floor panel In the case of air space), so the air in the underfloor space passes through the ventilation space. Therefore, since air cannot flow, condensation tends to form on the surfaces of interior wall materials, etc. This causes mold and rot to occur on the interior walls. In particular, insulation material is installed on the exterior wall material side. If the ventilation space is covered by sunlight, it will not be possible to heat it, so Condensation is likely to occur.

[0005] Therefore, the present invention was devised, and its purpose is to Insulates the space between the room and the room, and prevents condensation from forming on walls such as interior wall materials. Our goal is to provide insulated floor panels that can.

[0006]

[Means to solve the problem]

The measures taken by the present invention to achieve the above objectives correspond to the examples. The description will be given below using the reference numerals used in the drawings.

[0007] That is, the structure of the heat insulating floor panel according to the present invention is as shown in FIGS. 1 to 5. ``Air flows through the space under the floor of the house and the ventilation space formed between the exterior and interior wall materials. A heat insulating floor panel 100 disposed to pass through, The heat insulating floor panel 100 was fixed on the bars 10 arranged oppositely and on the bars 10. A plate material 20, a face material 30 arranged and fixed approximately parallel to the plate material 20, and these bar materials 10 , foamable resin filled and solidified in the space formed by the plate material 20 and the face material 30 Consisting of a heat insulating material 40, A cutout in the 40 sides of the foam resin insulation material that communicates the underfloor space with the ventilation space. A heat insulating floor panel 100 characterized by comprising a section 50. The content is

[0008]

[Effect of invention]

By the above means, the heat insulating floor panel according to the present invention is produced as shown in FIGS. 1 to 5. As shown in FIG. Transfer of heat to and from 0b is suppressed. In addition, this heat insulating floor panel 100 includes a bar 1 0, the foamable resin filled in the space formed by the plate material 20 and the face material 30 is expanded. It foams and solidifies to form a foamable resin insulation material 40 with voids, making it lightweight. becomes.

[0009] The air in the underfloor space 70a flows through the cutout 50 provided in the insulating floor panel 100. Since air passes through the ventilation space 80, this air flow causes a break in the ventilation space 80. Condensation on the wall surfaces of the heat material 91 and the inner wall material 92 is suppressed.

【Example】

Examples of the present invention will be explained in detail with reference to the drawings below, but these are representative ones. The present invention is not limited to this example. first, As shown in FIGS. 1 to 4, rods 10 made of natural wood such as cedar, pine, and toga are arranged opposite to each other. , a plate 20 made of plywood fixed on the bar 10, and a plate 20 fixed approximately parallel to the plate 20. The paper face materials 30 arranged and fixed at intervals of and a foamable resin heat insulating material 40 formed by the face material 30.

[0011] Further, on the side surface of this heat insulating floor panel 100, a foamed resin injected into the space is provided. In order to prevent leakage, plugging materials 60a and 60b are attached and fixed in advance. Said Foamable resins include urethane resin, isocyanurate resin, phenolic resin, and lily. A synthetic resin such as a resin containing a foaming material such as Freon may be used. In order to communicate the underfloor space 71 and the ventilation space 80, a foam resin insulation material 4 A notch 50 of 10 mm x 243 mm x 100 mm is provided on the 0th surface.

0012 Here, a method for manufacturing the heat insulating floor panel 100 will be described below. First, Figure 1 - As shown in FIG. The facing materials 30 are arranged and fixed approximately parallel to each other so as to form a space on the plate material 20 between the materials 10. Ru. At this time, cut out a 10 mm x 243 mm x 100 mm mold material (not shown) into the cutout. It is placed and fixed at a location located at 50. Next, the injection provided on the surface of the occlusion material 60a The foamable resin is injected into the space through the port 61. Then a heat press machine (as shown) The foamable resin is foamed by heat-pressing from above the face material 30 with The foamed resin insulation material 40 is solidified by cooling and expanding. to form. Next, the mold material is removed from the foamed resin insulation material 40 and cut out. 50 is formed.

[0013] As a result, the bar material 10, the plate material 20, the face material 30, and the foamed resin insulation material are integrated. A heat insulating floor panel 10 having cutout portions 50 on the foam resin heat insulating material 40 side. 0 is manufactured. Further, the cutout portion 50 can be formed without using the mold material. After forming the foamable resin heat insulating material 40 by heat-pressing, it is cut using various cutting machines, etc. It may also be formed by cutting out.

[0014] In addition, the heat insulating floor panel 100 obtained in this way is suitable for the underfloor space 70a of a house. Also, there is a so-called intra-wall air circulation structure in which air circulates between the ventilation space 80 and the attic. can be used. In this case, it is possible to prevent condensation from forming on the walls of the attic. At the same time, the above-mentioned circulation structure has the function of keeping the temperature throughout the house uniform. Ru.

[0015]

[Effect of the idea]

As explained above, the use of the insulated floor panel according to the present invention provides the following effects: Ru. In other words, the heat insulating floor panel according to the present invention is made of foam resin heat insulating material. This suppresses the transfer of heat between the space under the floor of the house and the interior of the house. It is possible to save energy. In addition, voids are created in the foam resin insulation material. Because of this, the insulated floor panel itself is lightweight, making it easy to install on site. .

[0016] Since a cutout is provided on the foam insulation material side of this insulation floor panel, this Air from the underfloor space passes through the cutout and fills the ventilation space formed between the outer and inner wall materials. This prevents condensation from forming on the walls, etc. within this ventilation space. This can prevent mold and rot caused by condensation.
