  The present invention relates to an airtight structural panel for a building such as a house used for an outer wall panel, a roof panel, a floor panel, etc., and relates to a vacuum heat insulating panel that ensures high heat insulation and sound insulation by constantly maintaining a vacuum state.

In particular, only human beings continue to consume a lot of energy such as enormous oil, coal, and natural gas for heating and cooling in order to obtain comfortable living.
Considering the maintenance of an environment friendly to the earth with few natural disasters, if we continue to consume oil, coal, and natural gas, which are valuable resources that cannot be regenerated, air pollution will increase and global warming will accelerate. . It is said that the possibility of this being hit by natural disasters associated with abnormal weather such as deadly wind and flood damage and desertification is extremely high.
Valuable underground resources such as oil, coal, and natural gas should be used with care, and rather than being used as fuel, it should be directed to creating products for the co-prosperity of coexistence and enrichment of humanity. It can be said that human beings are at a stage where basic indicators must be agreed globally regarding the effective use of global resources.

By the way, in recent years, social needs have been widespread and awareness of global warming is increasing.
Among them, there are strong demands for convenience and comfort in buildings such as houses. For example, the development of housing construction methods that incorporate many ingenuity related to safety, security, health, healing, and energy conservation is currently underway. is there.
In particular, with regard to the prevention of global warming, efforts are being made to achieve high airtightness and high thermal insulation based on an appropriate 24-hour mechanical ventilation system, and various other construction methods and measures are taken to prevent global warming. ing. However, most of the current high airtight and highly insulated houses are mainly insulated with glass wool or rock wool, and the insulation insulation method using a large amount of petroleum-based foamed urethane or polystyrene foam is the mainstream. The law is vulnerable to fires, and it cannot be said that it is a home building method that is friendly to the global environment, such as using many building materials that are difficult to recycle.

Therefore, we focused on high heat insulation and sound insulation using vacuum.
Though the idea of vacuum insulation has been around for a long time, it has been put into practical use only by vacuum insulation materials and vacuum window glass that have been evacuated at the factory. The current situation has not yet been reached.

  In view of the above circumstances, in order to greatly advance the heat insulation and sound insulation method using vacuum in buildings such as houses, etc.High heat insulation performance and sound insulation performance are achieved by combining a vacuum heat insulation panel and a vacuum control device for outer wall panels, roof panels, floor panels, etc. The purpose is to provide vacuum insulation panels for residential buildings such as semi-permanently stable maintenance.

In order to achieve the above object, the present invention has taken the following technical means.
First, a metal suction nozzle is provided at one or a plurality of locations on an airtight structure panel in which a gap holding member for holding an airtight space portion having a large space volume is sandwiched between two metal plate members and the periphery is welded. A vacuum heat insulating panel that is welded and can evacuate the airtight space by connecting a vacuum pump to the suction nozzle.
Second, the gap holding member is made of waste paper, wood, an inorganic building material board, porous ceramics, or a fiber heat insulating material.
Thirdly, the shape of the gap holding member is characterized by having a high compressive strength performance and minimizing the contact area with the metal plate material, or by making only one side concave.
Fourth, when the radiant heat is blocked by the structure and structure of the gap holding member, it is composed of two heat insulating materials and one aluminum sheet, and the aluminum sheet is sandwiched between the two heat insulating materials. It is characterized by being.

By the present invention, it is possible to greatly advance the vacuum insulation using vacuum in the heat insulation method of buildings such as houses. ・ High insulation by combining vacuum insulation panels such as outer wall panels, roof panels, floor panels and vacuum control devices. Performance and sound insulation performance can be maintained semi-permanently and with less energy.
For example, if solar power generation is used, a building such as a house that can be insulated by sunlight can be realized.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic diagram of a plane and a cross section of a vacuum heat insulation panel sandwiching a gap holding member composed of two honeycomb structural plates and one aluminum sheet.
FIG. 2 is a schematic view of a cross section of the gap holding member.
FIG. 3 is a schematic view of a cross section of the gap holding member.

1 shows a vacuum heat insulation panel 30. The vacuum heat insulation panel 30 has a gap holding member 40 sandwiched between two metal plate members 10 and surroundings of the two metal plate members 10. FIG. It is an airtight structure panel that is laser welded. And the metal suction nozzles 21 and 25 are welded to the both ends of this airtight structure panel, and it is the vacuum heat insulation panel 30 which can always be evacuated.
Therefore, in order to improve the heat insulation performance and the sound insulation performance, an airtight structure panel in which a gap holding member 40 for holding the airtight space 50 having a large space volume is sandwiched between the two metal plate members 10 and the periphery is welded is provided with metal at both ends. The suction nozzles 21 and 25 are made of, and a vacuum pump is connected to one of the suction nozzles 21 so that the other suction nozzle 25 can communicate with another vacuum heat insulation panel 30.
And it is the vacuum heat insulation panel 30 which can ensure heat insulation performance and sound insulation performance semipermanently by evacuating the said airtight space part 50 of the vacuum heat insulation panel 30. FIG.

The material of the gap holding member 40 is a heat-insulating material of recycled waste paper, and the shape thereof is a plate material having a high compression strength performance and having a concave honeycomb structure only on one side.
The size of the honeycomb shape of the honeycomb structure plate 45 having a concave shape only on one side is the maximum that can sufficiently withstand the degree of absolute vacuum, and by ensuring a wide space volume, heat transfer from one metal plate 10a to the other metal plate 10b is achieved. I try to keep it to a minimum.

  Next, the structure and structure of the gap holding member 40 is composed of two honeycomb structure plate members 45 each having a concave shape on one side and one aluminum sheet 80 in order to block radiation heat. The honeycomb structure plate member 45 has a structure and a structure that enhances the effect of blocking the radiant heat by the gap holding member 40 having a structure in which the honeycomb structure surfaces 49 sandwich the aluminum sheet 80 therebetween.

  The vacuum heat insulation panel 30 constructed with the gap holding member 40 having this structure and structure uses two stainless steel thin plate materials, but both sides of the gap holding member 40 are smooth surfaces, so that they are vacuum insulated even if they are evacuated. Since the surface of the stainless steel plate material of the panel 30 can ensure smoothness, no problem occurs even when a ceramic tile is pasted as an outer wall panel.

  Therefore, the use of the vacuum insulation panel 30 for building materials for buildings such as houses, outer wall panels, roof panels, floor panels, etc. makes it possible to construct buildings with high insulation properties such as thermos bottles and is friendly to the global environment. The vacuum insulation panel 30 is made of a material that can be easily recycled.

  In the third embodiment, FIG. 3 is a gap holding member 42 having a material, structure and structure different from those of the gap holding member 40 and the gap holding member 41. The material of the surface holding gap member 42 is an inorganic material. Only one side of the building material board plate 47 is a gap holding member 42 that combines the mountain wave type porous ceramic plate 48.

The present invention is not limited to the embodiment and can be modified as follows.
In the vacuum heat insulation panel of the present invention, two metal plates are welded, but a method such as bonding may be used.
In addition, the gap holding member may be a combination different in the material and shape of the gap holding member, for example, a gap holding member having a different configuration or structure may be used, such as using a heat-insulating material that is different from the concave shape only on one side. There are no restrictions or limitations.
