Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hard foamed resin heat insulating plate for buildings, and more particularly to a hard foamed resin heat insulating plate for buildings that can be easily attached as a heat insulating member such as a wall, floor, or ceiling of a building.

[0002]

[Prior art]

 A heat insulating material is inserted into a space formed between supporting members such as pillars or joists for the purpose of enhancing heat insulating property in a wall, floor, ceiling, etc. of a building. Conventionally, flexible materials such as glass wool that can easily take any size and shape have been used as heat insulating materials, but in recent years, hard foamed resin materials such as rigid polyurethane foam and polystyrene foam have been used as thermal insulation materials. It is widely used because of its excellent properties, light weight, and relative ease of processing. The rigid foamed resin plate formed by extrusion molding is cut into almost the same size as the space between the support members to be inserted, and inserted into the space such as the wall where heat insulation should be performed. An appropriate caulking material or a piece of soft foamed resin heat insulating plate is filled in the gap between the hard foamed resin plates.

[0003]

[Problems to be solved by the device]

 Although rigid foamed resin materials such as expanded polystyrene have high compression resistance and are effectively used as building materials, on the other hand, they hardly deform after foam molding, and if they do, the bubbles will break. Or accompanied by deformation. Therefore, when heat insulating construction of a building is performed using such a hard foam resin material, if a hard foam resin material that is cut to a size that is partially larger than the space to be inserted is used, it is When inserted into the cell, it involves local bubble destruction. As a result, the installation becomes unstable and the heat insulation is also impaired.

[0004] Therefore, in normal heat insulation construction, it is necessary to pay sufficient attention to mold or cut into the same size as the space to be inserted, or to mold or cut to a slightly smaller size and to insert after cutting as necessary. Sealing is performed by filling the gap with caulking material or a piece of soft foamed resin heat insulating plate. Forming and cutting into the same size as the space to be inserted requires careful work in itself, and even if the same size is prepared, the building to be heat-insulated may vary depending on the construction site. In some cases, assembly errors may occur, and it is virtually difficult to assemble the rigid foam resin material between the support members of the building without any gaps.

[0005] If the molded product is cut and cut into a slightly smaller size in advance and the gap created after assembly is sealed with a separately prepared caulking material or a piece of soft foamed resin heat insulating plate, etc. Although it is possible to deal with the error and the bubbles are not broken in the hard foamed resin material and the sealing performance is not deteriorated, it is necessary to always prepare a caulking material etc. as a sealing and filling material at the construction site. At the same time, it is difficult to fill the narrow gap with a caulking material. In the case of a wide gap, it can be easily filled, but the lack of stability in the mounting naturally limits the gap.

An object of the present invention is to eliminate the above-mentioned inconvenience when the hard foamed resin plate is used as a heat insulating material for a building, and more specifically, requires heat insulating for a building. It can be installed securely in a location without causing damage such as air bubble destruction, and the gap between the support and the support member can be easily and reliably installed without the need to separately prepare a sealing material for filling at the construction site. An object of the present invention is to provide a rigid foamed resin heat insulating plate that can be hermetically sealed.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems and to achieve the object, the present invention provides a heat insulating plate made of hard foamed resin, which is installed between support members of a building, and a support member to which the hard foamed resin heat insulating plate should be installed. It is formed to have a width slightly smaller than the space between them, and at least one surface thereof is laminated with a soft resin foam sheet having an area larger than the surface area of the hard foam resin plate.

The material of the hard foam resin plate is not particularly limited, and a polyurethane foam plate, a polystyrene foam plate, a polymethylmethacrylate foam plate, or the like can be selectively used. As the soft resin foam sheet laminated on at least one surface of the hard foam resin plate, a polystyrene foam sheet, a polypropylene foam sheet, a polyurethane soft foam sheet having a thickness of about 0.5 to 20 mm, or these soft foam sheets It is effective to use a sheet with a soft film such as polyethylene or a reinforcing sheet such as non-woven fabric attached to the surface of the sheet. The area of the soft resin foam sheet is not particularly limited, but hard foam resin as a heat insulating material is used. It is practical that it is about 110 to 130% of the surface area of the material.

[0009]

[Work]

 The hard foam resin insulation board for buildings according to the present invention was originally made to have a size slightly smaller than the space where it should be installed, and during construction, bubbles around the hard foam resin board should not be destroyed. It can be easily inserted into a mounting space such as between columns without generating. After insertion, the portion of the soft resin foam sheet that is out of the peripheral portion of the hard foam resin plate is pushed into the gap existing between the support member and the hard foam resin plate using an appropriate pushing tool. The soft resin foam sheet may be inserted between the support members with the surface side where the flexible resin foam sheets are laminated and bonded facing forward.In that case, the soft resin foam sheet portion that is outside the peripheral portion of the hard foam resin plate is automatically The gap between the hard foam resin plate and the support member, and seals the gap. In both cases, the gap is easily and reliably sealed.

The soft resin foam sheet has appropriate tensile resistance, flexibility, and elasticity, and it is necessary to selectively push in an amount of the soft resin foam sheet that is necessary for sealing according to the size of the gap that is generated. Is possible. After pressing, the heat insulation work is completed by cutting and removing the remaining sheet part if necessary. Also, the portion of the soft resin foam sheet that is in contact with the hard foam resin plate surface will function as a heat insulating material, and the heat insulating performance of the hard foam resin insulating plate for buildings as a whole will be improved.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 1 is a perspective view showing an embodiment of a rigid foamed resin heat insulating plate for a building according to the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG. In the figure, reference numeral 1 is a plate made of a rigid foamed resin material such as extruded polystyrene foam (trade name: Esren Foam SU, manufactured by Sekisui Plastics Co., Ltd.) that functions as a heat insulating plate. A soft foam resin sheet 2 such as a polyethylene foam sheet (trade name: Literon S # 58, manufactured by Sekisui Plastics Co., Ltd.) is adhesively laminated on the surface. As described above, the rigid foamed resin plate 1 is formed by cutting or the like so that it is narrower than the space between the supporting members of the building to which it is attached by about 10 mm.

FIG. 3 is a cross-sectional view showing a state where the above-mentioned heat insulating plate is attached between columns of a building. As shown in FIG. 3A, the width a of the rigid foam resin plate 1 is two columns 10, 10. The gap b, b'is formed between the rigid foamed resin plate 1 and the column. At the time of construction, press the necessary amount of the soft foamed resin sheet 2a, which is a portion protruding from the hard foamed resin plate 1, into the gaps b and b'by using an appropriate tool such as a spatula made of plastic. insert. FIG. 3b shows the state after being pushed in. In this example, the soft foamed resin sheet 2a is doubly pushed in. As described above, the soft foamed resin sheet 2 has appropriate elasticity and tensile resistance and also has heat insulating properties. Therefore, the flexible foamed resin sheet 2 is appropriately pushed into the gaps b and b ', so that No. 1 is securely fixed, and the gap between it and the column is completely airtight.

FIG. 4 a shows another embodiment of the method of attaching the rigid foamed resin plate 1. In this case, the hard foam resin plate 1 is inserted between the columns 10 and 10 with the front surface side on which the soft resin foam sheets 2 are laminated and bonded facing forward. In this case, the soft resin foam sheet portion 2a protruding from the peripheral portion of the hard foam resin plate 1 automatically enters the gap b between the rigid foam resin plate 1 and the pillar 10 at the same time as it is inserted, and as shown in FIG. As shown in the figure, when the insertion is completed, the work of sealing the gap b is completed.

FIG. 5a shows another embodiment of the heat insulating plate according to the present invention, in which soft foam resin sheets 2 and 20 are adhesively laminated on both sides of a hard foam resin plate 1. The two soft foamed resin sheets 2 and 20 may have the same size, or one of the soft foamed resin sheets 20 may have a smaller size than the other, as shown in the figure. Further, the thickness may be the same or different. Further, the two soft foam resin sheets 2 and 20 may be made of the same material or different materials.

FIG. 5b shows the insulation shown in FIG. 5a installed between the columns 10, 10 of the building. As shown in the figure, in this case, the protruding portions 2a and 20a of the soft foam resin sheets 2 and 20 can be pushed into the gaps from both the front and back surfaces of the mounting surface, and the sealing performance can be further ensured. When two soft foam resin sheets 2 and 20 having different materials, sizes and thicknesses are used, the size of the gap can be dealt with appropriately. That is, for example, when using a heat insulating plate to which two soft foam resin sheets 2 and 20 having different thicknesses are attached, the two soft foam resin sheets 2 and 20 may be selectively or appropriately overlapped. By pushing in, a more suitable sealed state can be formed according to the size of various gaps.

In any case, the portion of the soft foamed resin sheet not used for sealing the gap can be cut and removed as necessary. The hard foam resin insulation board for buildings of the present invention can be securely attached to the building without causing damage to the hard foam resin boards, and a separate sealing material is also provided. Even if this is not done, the gap between the support member and the support member can be easily and reliably sealed. In addition, the soft foamed resin sheet adhered to one or both surfaces not only functions as a sealant at the part protruding from the hard foamed resin plate as described above, but also sticks to the surface part of the hard foamed resin plate. Naturally, the part that has a heat insulating function also improves the heat insulating function as a rigid foamed resin heat insulating plate.

Next, a practical example of the hard foam resin insulation board for a building according to the present invention will be described. The following was manufactured as a heat insulating plate to be installed in a place where the distance between columns is 376 mm.
