[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel which is fitted between frames of a wooden building to construct a wall having excellent heat insulating properties and airtightness.

[0002]

2. Description of the Related Art In order to provide a wooden building capable of saving energy required for cooling and heating, a heat insulating panel capable of constructing a wall excellent in heat insulation and airtightness is provided by a frame (post or stud, base, trunk, girder, etc.). ) Is used in a form incorporated during the process, and the ratio tends to gradually increase. Under such an environment, as shown in FIG. 9, a conventional heat insulating panel is provided with a heat insulating material 6 in a wooden frame 62 fixed to one surface of a load-bearing wall face material 61.
3, a gap between the outer periphery of the heat insulating material and the inner wall of the frame body 62 is filled with a caulking material 64, and a band-shaped airtight material 65 having elasticity is attached to the outer periphery of the frame body 62 to form a panel body 67.
There is a heat insulating panel 60 in which an airtight material 66 is similarly adhered to a flange portion 68 on the outer periphery of the plate surface of the load-bearing wall surface material 61 that protrudes outside the frame body 62. As this type of panel, the frame is made of a resin extruded material such as hard vinyl chloride with an airtight part integrally molded of soft vinyl chloride resin, etc., and a rigid polyurethane is injected and foamed into the frame to form a panel body. Has also been proposed. Although not particularly shown, there is also a configuration in which the flange portion 68 of the heat insulating panel is eliminated and can be fixed at an arbitrary position inside the shaft assembly. Also, as shown in FIG.
The frame 62 made of wood or hard resin of the heat insulating panel 60 shown in FIG. 9 is eliminated, and a band-shaped airtight material 74 having elasticity is directly provided on the outer periphery of the side surface of a heat insulating material 72 made of foamed resin or the like to form a panel body 75. There is a heat insulation panel 70 which is fixed to the load-bearing wall face material 71 with an adhesive or the like, and further has an airtight material 73 adhered to a flange portion 76 of the face material. Further, as shown in FIG. 11, a fin-shaped fin made of a soft resin or the like is formed in a mounting groove provided over the entire side surface of a heat insulating material 82 made of a foamed resin or the like integrated with a wood screw or an adhesive with a face material 81 for a load-bearing wall. The airtight members 83 and 84 are fitted to form an airtight portion to form a panel main body 86,
There is also an improved heat insulation panel 80 in which an airtight material 85 is similarly adhered to a flange portion 89 of the same. A method of attaching these heat insulating panels to the frame will be described with reference to FIG.
The panel body 67 is fitted into the frame assembly 20, and the airtight material 65 is brought into contact with the inner peripheral surface (the side surface of the column, the upper surface of the base, the lower surface of the trunk) of the frame assembly 20, and the airtight material 66 is It is attached by being brought into contact with the outside or indoor side surface and fixed with nails 21 or the like.

[0003]

[Problems to be Solved by the Invention] The wave of high insulation and high airtightness of houses started in Hokkaido with the aim of comfort and energy saving, coupled with the growing demand for heat insulation in the Okinawa Kyushu region, However, the proposed next-generation energy conservation standard announced by the Ministry of Construction further strengthens the existing new energy conservation standard, and it is thought that insulation and airtightness will become more and more sophisticated. However, the thermal conductivity of the thermal insulation panel is determined by the thermal conductivity of the thermal insulation used, whereas the rigid polyurethane foam which belongs to the highest thermal insulation class has a thermal conductivity of 0.0145 Kc.
The limit is al / h 限界 cm, and it is actually difficult to improve it. If the thermal conductivity does not increase, there is a method of increasing the thickness to increase the performance, but for example, in the case of a wooden house, the pillar size constituting the frame is generally 90 to 120 mm square and the thickness of the heat insulating material is made larger This is not possible with the construction method. In addition, there is also a problem that an increase in thickness increases a necessary material amount. Further, as shown in FIG. 12, when the panel main body 67 has the same thickness as the frame 20, there is no room for piping and wiring inside the wall. Therefore, as shown in FIG. 13 and FIG. 14, the heat insulating material 93 inside the frame body 92 is formed in a concave shape to form the pipe space 9.
Although an example in which 7 is provided has been proposed, it is not practical because it is difficult to manufacture and, above all, has the disadvantage of sacrificing heat insulation. Furthermore, these insulation panels are often produced in factories away from the construction site to improve the efficiency of construction work. The increased volume and weight not only raises material costs, but also makes handling and construction more difficult, further reducing transport efficiency to construction sites and increasing total costs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems which the above-mentioned various heat-insulating panels have in common, and enhances the heat-insulating performance without increasing the amount of materials and increases the thickness of the heat-insulating material. It is possible to provide a space for piping in the frame by reducing the thickness and weight, and at the same time improve the handling and workability, increase the transportation efficiency and provide a heat insulating panel with a simple structure that reduces the total cost and is easy to manufacture It is intended to do so.

[0005]

In order to achieve the above object, a heat insulating panel according to the present invention comprises a part of a heat insulating material which constitutes a panel body fitted between a pair of shafts, and has a heat conduction which is a fraction of a normal value. Replace it with a vacuum insulation member that has excellent heat insulation properties. The vacuum heat insulating member is constituted by filling and enclosing a core material having low thermal conductivity as a reinforcing material and a getter material for adsorbing gas in an outer envelope having gas barrier properties. For example, a laminated film of stainless steel foil and heat-weldable plastic is used for an outer container having a gas barrier property, a water-foamed open-celled rigid urethane foam is used for a core material, and a pore size of 8 to 13 angstroms is used for a getter agent. A vacuum heat insulating member having a thermal conductivity of 0.003 Kcal / h ゜ cm using synthetic zeolite is used. Further, a part or all of the vacuum heat insulating member is configured to be wrapped and protected by components of a heat insulating panel such as a surface material for a load-bearing wall, a frame, a heat insulating material or a moisture-proof sheet. The vacuum heat insulating member is an aggregate of one or several independent vacuum heat insulating members. Further, the vacuum heat insulating member is fixed to the face wall material constituting the heat insulating panel with an adhesive or the like, is fitted into a groove provided in the frame, or the ear of the vacuum heat insulating member is pressed with the frame. It is fixed and wrapped with a heat insulating material such as foam resin. A recycled material such as polyurethane may be used for the core material, and a recycled material such as hard vinyl chloride may be used for the frame.

[0006]

According to the present invention, as described above, a part of the heat insulating material is replaced by a vacuum heat insulating member having excellent heat insulating properties, so that several levels of heat insulating performance can be obtained without changing the thickness of the heat insulating panel. . The vacuum insulation member reduces the thermal conductivity by evacuating the inside of the container, so there is no need to increase the amount of material,
In addition, the degree of vacuum is maintained for a long time by the getter agent,
Moreover, since the vacuum heat insulating member is wrapped and protected by components of the heat insulating panel such as a load-bearing wall surface material, a frame, a heat insulating material, or a moisture-proof sheet, the heat insulating performance can be maintained for a long time without being damaged during transportation or construction. Even if a nail or the like is mistakenly damaged, the deterioration of the heat insulating performance can be minimized because the vacuum heat insulating member is an aggregate of one or several independent vacuum heat insulating members. Therefore, even if the thickness of the heat insulating material is reduced for the purpose of creating a space for piping, improving the handling and workability, and improving the transport efficiency, the heat insulating performance is not deteriorated, and the performance can be secured for a long time. Further, the vacuum heat insulating member is fixed to the face wall material constituting the heat insulating panel with an adhesive or the like, is fitted into a groove provided in the frame, or the ear of the vacuum heat insulating member is pressed with the frame. Since the structure is simple enough to be fixed and wrapped with a heat insulating material such as a foamed resin, the manufacturing is easy and the total cost can be reduced. By using recycled materials such as polyurethane and hard vinyl chloride, the cost can be further reduced and the earth can be made more environmentally friendly.
