Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a heat insulating structure applied to external wall panels, floor panels, ceiling panels, etc.

[Background technology]

A typical panel consists of a steel frame with panels attached to both sides, and the inside filled with a heat insulator such as glass wool.

However, it is not easy to insert the heat insulator into the panel, and the work requires a long time, and glass fibers scatter from the heat insulator, making the work even more difficult. In addition, there was a problem in that condensed water inside the panel promoted rusting of the iron frame and decay of the wooden parts.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a heat insulating structure that facilitates the insertion of a heat insulator into a panel and prevents rust and decay within the panel.

[Disclosure of the invention]

The heat insulating structure of the present invention includes a heat insulating body and a plate-shaped body provided on at least one side of the heat insulating body, the plate-like body protruding to a surface opposite to the heat insulating body, and the side of the heat insulating body becomes a recessed space. A small ventilation hole is provided in the projection.

According to the structure of this invention, since the plate-like body is provided on at least one side of the heat-insulating body, the heat-insulating body can be inserted into the panel frame together with the plate-like body, and the heat-insulating body, which is difficult to handle, can be inserted into the panel frame alone. The insertion work is easier than in the case of Further, even if the heat insulating body is made of glass fiber or the like, by covering it with a plate-like body, it is possible to prevent the glass fiber and the like from scattering during the insertion operation.

Further, since the plate-like body has projections formed therein, a ventilation space is formed between the panel face material and the heat insulating body when the plate-like body is inserted into the panel. Therefore, it is possible to prevent dew condensation inside the panel, and to prevent rusting of the metal parts of the panel and rotting of the wooden part. Since the plate-like body is provided with ventilation holes and the protrusions are further provided with small ventilation holes, the air permeability can be further improved, and the air permeability between the plate-like body and the heat insulating body can also be improved. In this case, the protrusion has a recessed space on the back side, and a small ventilation hole is formed in this protrusion, so that the entire bottom of the protrusion leaves the heat insulator and the plate-like body and the heat insulator come into contact with each other. The area can be made as small as possible, and ventilation within the protrusion can also be achieved. Therefore, the air permeability between the plate-shaped body and the heat insulating body is very good, and dew condensation on the surface of the cross-sectional body can be reliably prevented.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 and 2. This heat insulation structure includes a heat insulator 1,
A plate-like body 2 provided on one side of the heat insulating body 1,
The plate-like body 2 is provided with a protrusion 3 and a ventilation hole 4 which protrude from the surface opposite to the heat insulator 1 and form a recessed space on the side of the heat insulator 1, and a small vent hole 5 is provided in the protrusion 4. The plate-shaped body 2 further has a piping cavity 6 on the back side.
A groove-shaped portion 7 is provided in a protruding manner. The plate-shaped body 2 is bonded to the heat insulating body 1 with an adhesive.

The heat insulator 1 is made of glass wool, rock wool, etc., and has a recess into which the groove 7 of the plate-like member 2 fits. The heat insulator 1 may be covered with a bag. The plate-like body 2 is made of a plastic molded product such as polyvinyl chloride. Although a large number of projections 3 and ventilation holes 4 are provided distributed throughout the plate-like body 2, their positions are not particularly limited. Also, protrusion 3
The shape of the ventilation hole 4 is also not limited to the illustrated example. Although the small ventilation hole 5 is formed on two opposing sides of the projection 3, there may be only one small ventilation hole 5. Small ventilation hole 5
The holes also serve as holes for inserting electric wires. The piping cavity 6 is provided approximately in the center of the back surface of the plate-like body 2 along its length, and has a cross-sectional shape large enough to allow insertion of a paper tube for inserting electric wires.

FIG. 2 shows an example in which this heat insulation structure is applied to an external wall panel, in which the protrusion 3 of the plate-like body 2 comes into contact with the back surface of the external panel surface material 8 (for example, a slate board), and the heat insulating body 1 A ventilation space 10 is formed between them. Indoor panel surface material 9 (e.g. gypsum board)
A heat insulator 1 is in close contact with the back surface of the. 11 is a panel frame.

According to this configuration, the plate-shaped body 2 is provided on one side of the heat insulating body 1.
Since the heat insulating body 1 can be inserted into the panel frame 11 together with the plate-shaped body 2, the insertion work becomes easier compared to the case where the heat insulating body 1, which is difficult to handle, is inserted into the panel frame 11 alone. Further, even if the heat insulating body 1 is made of glass fiber or the like, by covering it with the plate-shaped body 2, scattering of the glass fiber or the like during the insertion operation can be prevented.

In addition, since the protrusion 3 is formed on the plate-shaped body 2,
When inserted into a panel, a ventilation space 10 is formed between the panel panel material 8 and the heat insulator 1. Therefore, it is possible to prevent dew condensation inside the panel, and prevent rusting of the metal part of the panel and rotting of the wooden part. Since the plate-shaped body 2 is provided with ventilation holes 4 and the protrusions 3 are further provided with small ventilation holes 5, the ventilation can be further improved, and the ventilation between the plate-shaped body 2 and the heat insulating body 1 can also be improved. I can figure it out. In this case, the protrusion 3 has a recessed space on the back side and a small ventilation hole 5 is formed in the protrusion 3, so that the entire bottom surface of the protrusion 3 is separated from the heat insulating body 1 and is insulated from the plate-like body 2. The contact area with the body 1 can be made as small as possible, and the inside of the protrusion 3 can be ventilated. Therefore, the air permeability between the plate-shaped body 2 and the heat insulating body 1 is very good, and dew condensation on the surface of the heat insulating body 1 can be reliably prevented.

By providing the piping cavity 6 in the plate-shaped body 2 in this manner, piping within the panel is facilitated, and displacement of the heat insulating body due to forced piping as in the past can be prevented. Furthermore, since the piping cavity 6 is formed integrally with the plate-shaped body 2, it is advantageous in terms of cost, and furthermore, the cavity 6 can be formed into any shape by changing the mold. can. Therefore, in addition to electrical conduits, water supply and drainage pipes, etc. can also be inserted into the cavity 6.

In addition, although the plate-shaped body 2 was provided on one side of the heat insulating body 1 in the above embodiment, it may be provided on both sides.

〔Effect of the invention〕

In the heat insulating structure of the present invention, since the plate-like body is provided on at least one side of the heat insulating body, the workability of inserting the heat insulating body into the panel is better than when inserting the heat insulating body alone, which is difficult to handle, into the panel. Further, since the plate-like body is provided with projections and ventilation holes, a ventilation space is formed between the heat insulator and the panel surface material, thereby improving air permeability. In particular, since the protrusion has a concave space on the back side and a small ventilation hole is formed in the protrusion, the contact area between the plate-shaped body and the heat insulating body can be made as small as possible to improve air permeability. These have the effect of preventing the panels from rusting and rotting.
