Description

  The present invention obtains heat insulation performance semipermanently by maintaining the degree of vacuum in a hermetic space part of a multi-layer high hermetic heat insulating member (hereinafter referred to as a high airtight heat insulating member) having one to a plurality of hermetic space parts with a vacuum controller. In addition, the present invention relates to a highly airtight insulating member for buildings such as a sash, a door, and a wall material, which is connected to a security system by detecting an abnormal change in the degree of vacuum.

  There are two methods of heat insulation for general houses: the inner heat insulation method and the outer heat insulation method. Recently, the latter heat insulation method is less likely to cause condensation and is considered to be better from the viewpoint of building life and health. In particular, the growth and increase of mold and mites in a house are greatly related to humidity, and when the humidity exceeds 70%, the growth and increase greatly change. For this purpose, many ideas have been made in the house, such as cutting off the source of moisture, increasing the heat insulation effect, preventing drafts, and incorporating natural ventilation.

  By the way, in recent years, there has been a widespread increase in social needs, and the development of housing construction methods with many ingenuity related to safety, security, health and healing, such as the suppression of global warming and the strengthening of crime prevention security, the pursuit of convenience and comfort, etc. The current situation is progressing. In the development of better housing construction methods, development of high airtightness and high thermal insulation has been promoted based on an appropriate 24-hour mechanical ventilation system, and many developments have been promoted as preventive measures against crime increase. .

There are many examples of the concept of vacuum insulation, and it is often common sense.
Next, as what connects the change of a pressure to a security system, it is disclosed by Unexamined-Japanese-Patent No. 2002-32870 and Unexamined-Japanese-Patent No. 6-4890, but all are gas enclosure systems.
JP 2002-32870 (enclosed with a gas higher than atmospheric pressure in a double-layer glass part) JP-A-6-4890 (enclose a gas lower than atmospheric pressure in a multi-layer glass part)

  Combines a vacuum control device that maintains semi-permanent insulation performance of a highly airtight insulation member and a security system. In particular, the development of highly airtight heat insulating members that are kept in vacuum, such as high heat insulating security sashes, doors and wall materials, is useful as building materials for safe, secure, healthy and comfortable houses.

  An object of the present invention is to combine a vacuum control device that maintains the heat insulation performance of a highly airtight heat insulating member semipermanently and an abnormal change in the degree of vacuum of the vacuum control device and a security guard system. The realization of high energy-saving housing for the future can greatly contribute to society by providing high airtight insulation members and vacuum control devices that can ensure high heat insulation performance and high safety, and this kind of development makes urban heat island phenomenon This can be linked to a significant reduction in environmental impact.

In order to achieve the above object, the present invention has taken the following technical means.
First, in the structural member having one to a plurality of airtight spaces (14) separated by two or more members, the airtight space (14) in order to keep the airtight space (14) in a vacuum at all times. Each highly airtight heat insulating member (10) provided with each suction connection nozzle (11) has a high heat insulating performance semipermanently, and the structural member itself can be reduced in weight and thickness.

  Secondly, in the structural member having one to a plurality of airtight spaces (14) separated by two or more members, the airtight space (14) in order to keep the airtight space (14) always in vacuum. Highly airtight insulation member (10) equipped with each suction connection nozzle (11), detecting abnormal changes in the degree of vacuum and connected to the security system (99), enhances and secures the security of the building Can be planned.

  Thirdly, the high airtight heat insulating member (10) is a building member used for a sash, a door, a fitted glass, a wall, a floor, a top plate, a roof or a building foundation, and the glass part of the sash, the door, the fitted glass. In the airtight space portion (14), the airtight space portion (14) even in the case where two glass plates have one airtight space or two or more glass plates have a plurality of airtight spaces. ) In the glass part, there is no gap holding member for holding the gap, and the high airtight heat insulating member (10) that holds the minimum gap according to the strength of each glass plate and the degree of vacuum controlled.

The degree of vacuum of each of the airtight spaces (14) can be arbitrarily controlled by the vacuum control device (80) connected to each suction connection nozzle (11) of the high airtight heat insulating member (10).

  In future homes, the highly airtight heat insulating member of the present invention and the vacuum control device connected to the high airtightness insulating member can aim for a safe, secure, healthy and comfortable home. High heat insulation performance and high safety can be secured by combining a vacuum control device that maintains the heat insulation performance of the high airtight heat insulation member semipermanently and a security system.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are conceptual views of a hermetic space portion of a glass portion of a sash, a door, or a fitted glass in the first embodiment of the present invention.
There is no gap holding member for holding the gap of the airtight space portion 14, and a multi-layer high airtight heat insulating member 10 that holds a minimum gap according to the strength of each glass and the degree of vacuum controlled. Thus, by ensuring the balance between the strength of each member and the degree of vacuum by the vacuum control device 80, it is possible to realize a transparent glass portion without a gap holding member.

  1 (a) and 1 (b) show that each glass 12 is reinforced with a laminated glass 15 in which the thickness of each glass 12 is increased to withstand each degree of vacuum or a special film is sandwiched between two glass plates. It is the high airtight heat insulation member 10 currently made.

  The glass plates, glass 91, glass 92, glass 93, and glass 94 of each of the multi-layer high airtight heat insulating member 10 in FIG. 1 are the minimum gaps required for vacuum insulation by design. Since the airtight space portion 95, the second airtight space portion 96, and the third airtight space portion 97 are disposed, the end portions of the airtight structure are made of gasket packing 13 or caulking, and are a multilayer glass.

  At least one suction connection nozzle 11 is disposed for each of the airtight space portions 14 of the first airtight space portion 95, the second airtight space portion 96, and the third airtight space portion 97. Each suction connection nozzle 11 and the high vacuum degree unit or medium vacuum degree unit of the vacuum control device 80 are connected by a high vacuum degree tube 81 and a medium vacuum degree tube 86, respectively. In the figure, the suction connection nozzle 11 of the second hermetic space 96 and the high vacuum degree tube 81 are coupled to the high vacuum degree of the vacuum controller 80, and the first hermetic space 95 and the third hermetic space 97 are intermediate. The vacuum degree tube 86 is connected to and communicated with the medium vacuum degree part.

  The vacuum control of the vacuum controller 80 is controlled to a high vacuum level close to absolute vacuum and a medium vacuum level about half of the absolute vacuum. Each vacuum degree is set according to the strength of the glass 91, the glass 92, the glass 93, and the glass 94.

  By having the first hermetic space portion 95, the second hermetic space portion 96, and the third hermetic space portion 97 that are controlled in this way, the second hermetic space portion 96 is maintained at a high vacuum level close to absolute vacuum and is high. Heat insulation performance can be obtained, and it is effective as a means for maintaining a high vacuum without increasing the thickness of the glass 91, glass 92, glass 93, and glass 94 more than necessary. That is, if a high degree of vacuum is to be maintained with only two glass plates, a considerably thick glass is required or a gap holding member is required.

  In the example, the airtight space portions 14 are formed in three places with four glasses 12. However, if the airtight space portions 14 are further increased from the illustration to reduce the difference in the degree of vacuum of each airtight space portion 14, the glass one by one. Even if the thickness of the airtight space portion 14 is reduced, it is possible to embody the multi-layer high airtight heat insulating member 10 that can secure an absolute vacuum portion without inserting a gap holding member in the airtight space portion 14.

  Next, regarding the security guard, an abnormal change in the vacuum degree of the airtight space 14 of the glass part of the sash, door, or fitted glass is detected and connected to the security guard system 99 for communication. In the figure, the detection unit for the abnormal change in the vacuum degree is the high vacuum degree side of the second hermetic space part 96, but is connected to the first hermetic space part 95 and the third hermetic space part 97 on the medium vacuum degree side. It may be the vacuum degree tube 86 side or both.

FIG.1 (b) is the high airtight heat insulation member 10 in the method strengthened with the laminated glass 15 which pinched | interposed and bonded the special film between the two glass plates.
FIG. 2C is a schematic diagram in which a vacuum control device is connected to a sash and a door and a security guard system is combined in the first embodiment of the present invention.
By not using a gap retaining member in the glass portion of the sash, door, or fitted glass that is the high airtight heat insulating member 10, the sash, the door, or the fitted glass has high heat insulation performance and high crime prevention while ensuring transparency without causing a sense of incongruity. The airtight heat insulating member 10 can be realized.

  A vacuum degree control method of the vacuum control device 80 will be described. The degree of vacuum is precisely controlled by the vacuum control valve 83 and the vacuum suppression valve 84 for controlling the degree of medium vacuum. The vacuum control valve 83 opens until the set vacuum level, and closes when the set vacuum level is reached. One vacuum suppression valve 84 has a role to prevent an excessive vacuum from being sucked in when outside air is sucked into the high vacuum after reaching the set vacuum.

FIG. 3 is a schematic view when a porous ceramic plate is used for a wall material, a floor material, a top plate material, and a roof material in the second embodiment of the present invention.
3 (e) and (f) shown in FIG. 3 exemplify a combination of two porous ceramic plates 20 having many independent pores that are widely used as residential building materials. Although the porous ceramic plate itself with many independent pores has high heat insulation performance, by combining the two porous ceramic plates 20 and providing the airtight space portion 14 having a high vacuum degree, for example, an existing 120 mm porous ceramic plate is provided. By providing two 60 mm porous ceramic plates 20 and providing an airtight space 14 with a high degree of vacuum, the heat insulation performance far higher than that of the former can be ensured.
Accordingly, the thickness of the two 60 mm porous ceramic plates 20 can finally be made considerably thinner than 120 mm.

  In the figure, the porous ceramic plate 22 on the outer wall side of the two porous ceramic plates 20 has a waterproof layer 25 and a coating, and the porous ceramic plate 24 on the other inner wall side has no waterproof layer and has a room humidity. Has a humidity control function. Further, the entire inner wall surface of the isolated airtight space portion 14 that is in a vacuum is painted so that air does not leak from the wall surface. However, if there is almost no influence on the vacuum control device 80, it is preferably not painted. Better.

Next, in FIG. 3 (g), since the highly airtight heat insulating member 10 having high heat insulating performance can be realized by vacuum heat insulation, the wall surface of the porous ceramic plate 24 is used as a direct wall surface in the room and is a lock as another heat insulating material. Without using wool, glass wool, cellulose fiber, or flame retardant foamed polystyrene, the high airtight heat insulating member 10 of the highest class non-combustible heat insulating structure that can be used for both internal heat insulation and external heat insulation can be realized. Since the porous ceramic plate 24, which is an inorganic plate, becomes the inner wall surface, it is good for health, and it is possible to approach the realization of a house construction method that does not generate toxic gas even in the event of a fire.

  With regard to security, the abnormalities in the building can be obtained anywhere by detecting abnormal changes in the degree of vacuum in the airtight space 14 that is isolated by the two porous ceramic plates 22 and 24 and forming a vacuum. Since the detection location and method of the abnormal change in the degree of vacuum are described in the first embodiment, the details are omitted.

FIG. 4 is a schematic view of a plywood panel, which is a wood-based 2 × 4 residential building material, a wall material, a floor material, a top plate material, and a roof material, according to a third embodiment of the present invention.
(H), (j), and (k) in FIG. 4 illustrate a plywood panel. This example is in the improvement of the heat insulation performance of the plywood panel which is a wood-based 2X4 residential building material. A gap holding member 36 is wrapped in a film back 37 such as a polyethylene film or a polyester film between two plywoods 32 that are structural face materials, and a film back 37 member that can withstand high vacuum is put into a laminated plywood. Highly airtight insulation of a high-grade vacuum insulation structure that combines both internal insulation and external insulation without using any other insulation materials such as rock wool, glass wool, cellulose fiber or flame retardant foamed polystyrene. The member 10 can be embodied.

  Concerning security, the abnormalities of the building are detected by detecting abnormal changes in the degree of vacuum in the airtight space 14 in the film back 37 that is wrapped in a polyethylene film or polyester film, etc. so as to withstand high vacuum, and connected to the network. Can be obtained anywhere. Since the detection location and method of the abnormal change in the degree of vacuum are described in the first embodiment, the details are omitted.

(M) of FIG. 5 is a schematic diagram showing the relationship between the outer heat insulating method and the air passage 55. A high airtight heat insulating member 10 for an outer wall in which a member capable of forming a high vacuum hermetic space portion 14 is bonded to an exterior material 52, and an external heat insulating method is illustrated as a heat insulating method for a house.
Ventilation is ensured by arranging a gap between the outer wall high hermetic heat insulating member 10 and the inner wall structural face material 53 as a ventilation path 55. The combination of securing the air passage 55 and the outer heat insulation method allows the construction of a 24-hour ventilation system that does not cause dew condensation in the air passage 55, and the foundation and the building can be integrated. Insulated housing can be realized.
I would like to compare with the inner heat insulation method of FIG. 5 (n) described later.

(N) of FIG. 5 is the schematic which shows the relationship between an internal heat insulation construction method and a ventilation path.
In the figure, an internal heat insulation method that is common to existing housing methods is illustrated. This is a general wood-based 2 × 4 building material plywood panel 77 in which rock wool, glass wool, or cellulose fiber, which is a heat insulating material 71, is placed between two plywoods 73 of residential building material.
Ventilation is a difficult house construction method for realizing a highly airtight and highly insulated house such that outside air flows directly under the floor or through the air passage 75 and increases the draft. Especially in winter, when the draft of a house is generated locally, it can be said that this part is a house construction method that is dangerous due to local condensation and the root of mold.

In this way, the heat insulation method for residential building materials is reduced to vacuum insulation, making the panel itself thinner and lighter, and using other heat insulation materials such as rock wool, glass wool, cellulose fiber, and flame retardant foamed polystyrene. Unnecessary building materials can be put into practical use.
In particular, the development of porous ceramic plates that can be used for both internal and external heat insulation can be a highly airtight insulation member of the finest thermal insulation structure. If a new house is rebuilt in the future, the amount of waste materials will be small, and it will be easy to separate and recycle waste materials, which will greatly reduce the cost of disposal.
In addition, since an abnormal change in the degree of vacuum can be detected and communication can be established, the communication can be transmitted to the mobile phone.
Therefore, the present invention minimizes the energy consumption in the house and minimizes the number, quantity and weight of the building materials for the house. It is possible to contribute to society.
Furthermore, according to the technical application of the present invention, the vacuum heat insulation method combined with the vacuum pump can maintain its heat insulation performance semi-permanently, for example, a domestic refrigerator, a heat insulation of a pipe through which high-temperature or low-temperature fluid flows, a cold district, etc. It can be applied as a thermal insulation method for crude oil pipes laid on the ground.
For piping structures that require periodic wall thickness inspection, it is possible to easily perform main wall thickness inspection simply by releasing a vacuum by providing a hand hole in the exterior piping of the main wall where fluid flow is required. It can be done.
In this example, the vacuum control method of the vacuum control device has been described by the control valve method. However, as another method, the method of setting the vacuum degree by changing the position of the water sealing depth, which is a water seal method, etc. May be.
