Description

[Detailed description of the invention] This invention consists of laminating and interposing synthetic resin sheets that form a large number of recesses on the back side of the panel, and by forming through holes in the recesses, air can be drawn into the recesses. This invention relates to an accordion-type insulation structure that allows access.

Conventionally, as a heat insulating material using a synthetic resin sheet such as polyethylene with many recesses formed on the back side, aluminum foil is pasted on one side of the synthetic resin and thermoplastic synthetic resin sheet, or metal powder printing is applied. A panel is used in which a suitable combination of these materials is used.

Although these heat insulating materials prevent heat conduction and block the transmission of radiant heat, and have excellent heat insulating effects, they have the disadvantage that they are inconvenient to handle.

That is, the recess of the synthetic resin sheet has a diameter of 5 to 5.
Since they are formed with a depth of 0 m7, 2 to 20 mm, and a ram thickness of 0.05 to 0.2 m7, a considerable amount of space will be required if they are stacked and interposed in a panel.

Insulating materials commonly used in construction and the like are often stored for long periods of time, and therefore require a large storage space.

This invention was proposed to eliminate the above drawbacks,
The purpose is to provide an accordion-type insulation material structure that is suitable for reducing storage space for insulation materials by compressing the synthetic resin sheet to reduce its volume when not in use, and returning it to its normal state when in use. There is something to do.

In order to achieve the above objectives, the present invention is an accordion-type heat insulator in which through-holes are formed in the recesses of synthetic resin sheets laminated and interposed in panels, and air is allowed to flow through the through-holes. It is characterized by its material structure.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIG. 1, panel 1 is an architectural panel such as a decorative board.

A synthetic resin sheet 2 such as polyethylene or polystyrene is attached to the panel 1.

A large number of recesses are formed in the synthetic resin sheet 2, and the recesses are sealed with a thermoplastic synthetic resin sheet 3.

Next, the synthetic resin sheet 2 is transferred to a thermoplastic synthetic resin sheet plate 3.
', and a panel 4 is attached to the other end.

Therefore, the synthetic resin sheet 2 is placed between the panels 1 and 4.

In addition, synthetic resin sheet 2 and thermoplastic synthetic leather sheet)
3. 3' is mixed with metal powder, aluminum foil is pasted on one side of the thermoplastic synthetic resin sheet plate 3, 3', and one side is printed with metal powder to form a glossy metal film. It is also possible to prevent the transfer of radiant heat.

FIG. 2 shows a state in which through holes 5 are formed in recesses of the synthetic resin sheet 2. As shown in FIG.

As a method for forming the through-hole 5, in addition to mechanically forming the through-hole, it is also possible to form the through-hole by bursting by pressing the panels 1 and 4 together with a roll or the like.

When the through holes 5 are formed in all the recesses, as shown in FIG. 3, by pressing the panels 1 and 4 together, the air in the recesses is released from the through holes 5 and the synthetic resin sheet 2 is crushed.

Therefore, the volume between panels 1 and 4 becomes narrow.

Next, when the panels 1 and 4 are pushed apart, air flows into the recess through the through hole 5, causing the recess to bulge and return to its original state.

Since the through hole 5 is a minute hole, the heat insulation effect is not affected by this hole.

FIG. 4 shows a state in which a heat insulating material having the above-mentioned synthetic resin sheet 2 as a main element is used in a building.

The panels 1 and 1' are arranged with studs 7 interposed therebetween.

Panel 1 and panel 4 are pushed apart by an inclusion 6 such as a spring or a rod.

In addition, there may be cases where the panels 1 and 4 are spread apart by nailing.

When the panels 1 and 4 are stretched apart, air flows into the recesses of the laminated synthetic resin sheets 2 as described above, thereby increasing the heat insulation effect.

Further, as mentioned above, by using thermoplastic synthetic resin sheets 3, 3' with aluminum foil or the like attached, or by mixing metal powder into the synthetic resin sheet 2 or thermoplastic synthetic resin sheet, even more heat insulation can be achieved. You can increase the effect.

On the other hand, if the inclusion 6 is removed and the panels 1 and 4 are pressed together, the air in the recesses of the synthetic resin sheet 2 will be released, resulting in the state shown in FIG. 3.

As is clear from the above explanation, according to the present invention,
The storage space for the heat insulating material can be reduced when not in use, and the normal heat insulating effect can be increased when in use.
