Abstract

PROBLEM TO BE SOLVED: To simplify the building construction work when attaching a gypsum board to a concrete wall surface by interposing insulation attaching pieces corresponding to a gypsum-based adhesive when attaching the gypsum boards to the concrete wall surface by spot adhering thereby attaching the gypsum- based adhesive to the gypsum boards. SOLUTION: Insulation attaching pieces 2 are adhered with an adhesive 6 to a concrete wall 1 as an exterior wall or partition, and the insulation attaching piece 2 and a gypsum board 4 are jointed with a gypsum-based adhesive 3. And in this insulation attaching piece 2, a hard urethane foamed body or fiber-based insulation material such as glass wool or rock wool or the outer surfaces of a filled portion such as soft urethane foamed body are covered with gypsum-based hardening body or hard resins. Thus, sufficient effects of sound shielding, non-dew condensation and thermal insulation can be obtained by using the insulation attaching pieces.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating mounting piece for a building interior panel and a mounting structure using the same. More specifically, the invention of this application is applicable to concrete walls of various buildings, such as inner surfaces of exterior wall concrete and partition concrete surfaces, which are inexpensive and require sound insulation effect, prevention of dew condensation, heat insulation effect, and heat resistance effect. The present invention relates to a heat-insulating mounting piece useful for mounting an interior board and a mounting structure using the same.

[0002]

2. Description of the Related Art Conventionally, in various buildings such as condominiums, hotels, inns, office buildings, etc., a building interior board is attached to a concrete wall surface and a cloth having various designs is provided on the upper side of the building interior board. It has been devised to make the interior of the room look beautiful.

[0003] Such a building interior board is required to have heat resistance in order to prevent the spread of the fire in the event of a fire, and is usually made of a heat resistant material such as gypsum board. ing. A GL method (gypsum liner method) is known as one of the mounting structures of the heat-resistant building interior board. In this method, as illustrated in FIG. 6, for example, 30 gypsum-based adhesives (102) are applied between a concrete wall (100) such as an outer wall or a partition and a gypsum board (101) serving as a building interior board.
It is spotted directly on the concrete (100) wall at intervals of 40 cm to 40 cm, and the gypsum board (101) is pressed to complete the foundation in the wall.

The gypsum board (101) is inexpensive and excellent in heat resistance. By the above-mentioned method, a mounting structure for a building interior board excellent in heat resistance is provided as a simple and excellent workability. Can be. However, on the other hand, regarding the mounting of the building interior board by such a GL method,
There were problems with (a) sound insulation and (b) dew formation and heat insulation.

[0005] That is, (a) With regard to the sound insulation, in such a structure, since all are made of a hard sound insulation material such as a concrete wall, a gypsum-based adhesive and a gypsum board, sound propagates through the solid. However, there is a problem that the sound insulation is very low. On the other hand, regarding (a) the problem of dew condensation, the concrete wall (100), the gypsum-based adhesive (102) and the gypsum board (101) of FIG. The surface temperature of the gypsum board facing the room or the surface temperature of the gypsum-based adhesive is likely to be the room dew point temperature. Therefore, particularly in the winter season, dew condensation easily occurs on the surface of the gypsum board and the gypsum-based adhesive, and as a result, the gypsum board that easily absorbs moisture is deformed, and mold is generated on the gypsum board. Was there.

As a countermeasure against such condensation, for example, as shown in FIG. 7, a foaming liquid for forming a hard urethane foam or the like is sprayed on the concrete wall (100), and the heat insulating layer (105) is formed on the outer wall concrete. There is a method of forming the entire upper surface. Since the rigid urethane foam has a heat insulating property, the heat insulating property is improved and dew condensation can be prevented.

Further, since only the heat insulating layer made of such a hard urethane foam does not have the above-mentioned sound insulation properties, for example, as shown in FIG. 8, soft face materials (106) are provided on both sides of the hard urethane foam. The formed one or, as illustrated in FIG. 9, one having a soft face material (106) on one side and a hard face material (107) on the other side is disposed on the inner surface of the concrete wall (100). It is also known to do.

However, in such a method, since the heat insulating layer is formed on the entire upper surface of the outer wall concrete, the cost is extremely high. Therefore, the invention of this application has been made in view of the above-mentioned drawbacks of the prior art, and enables an inexpensive, simple construction, and has a sound insulating property, a non-condensing property, and a heat insulating property. It is intended to provide a new means for mounting.

[0009]

According to the present invention, there is provided a gypsum-based adhesive which is spotted between a gypsum board and a concrete wall when the gypsum board is attached to the wall. Provided is a heat insulating mounting piece which is interposed and jointly mounts a gypsum board together with a gypsum-based adhesive.

The present invention also provides a heat-insulating mounting piece in which an adhesive is held in advance, and a heat-insulating mounting piece in which the outer surface of a fibrous or soft heat insulating material is covered with a hard body.
