DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite board for a building excellent in sound insulation and heat insulation and a floor structure using the composite board.

[0002]

2. Description of the Related Art Conventionally, in the construction of houses such as wooden, reinforced or steel-framed houses, the floor structure has a sound-insulating property against room noise and impact noise in order to maintain a comfortable habitability, and a heat insulating property for heat insulation and fire prevention. Is required. In wooden houses, especially apartments such as condominiums and apartments, the floor structure to prevent extra noise has become an important issue, and expensive noise insulation was used as a countermeasure and special construction that was troublesome. In some cases, the cost may be increased as a whole. As a floor structure having sound insulation and fire resistance, for example, Japanese Patent Application Laid-Open No.
One in which a gypsum board and a finishing material are sequentially laminated has been proposed.

[0003]

However, in a conventional floor structure in which a gypsum board and a finishing material are sequentially laminated on a floor substrate, the gypsum board is fragile and easily damaged, so that a weak corner portion is required during loading or construction. However, there is a drawback in that the handling of the material requires care and the work of laminating on site requires time and effort.

[0004] The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a composite board for a building, which has sound insulation and heat insulation properties, is easy to handle, can shorten the construction period, and is inexpensive, and a floor structure using the composite board.

[0005]

In order to achieve the above object, a composite board for a building according to the present invention is provided on one side or both sides of a gypsum board formed in a rectangular and standardized size. And a plate member formed in the same rectangular shape is laminated and integrally formed with an adhesive layer interposed therebetween. Since the surface of the gypsum board is covered with the plate material and integrated, the gypsum board can be protected, the handling is easy, the construction period can be shortened, and the cost can be reduced.

[0006] The board is preferably a plywood, a soft fiber board or a hard fiber board having water resistance, in that the surface of the gypsum board can be protected.

[0007] An adhesive layer is formed on the one side or both sides of a gypsum board formed in a rectangular shape with standardized dimensions on the floor support structure of a building by using an adhesive layer formed of the same rectangular shape. The composite board for buildings formed integrally with each other is spread without gaps, and the base material is spread on the upper surface of the composite board for building so that the joints do not overlap each other, and the finishing material is disposed on the upper surface of the base material. Alternatively, a finishing plate is disposed directly on the upper surface of the building composite plate. In addition to gypsum board having sound insulation and heat insulation,
Vibration and impact noise are not transmitted through joints.

In a floor structure of a building using the composite board 10 for a building, a joist 18 constituting a floor support structure 17 on the upper floor is used.
The building composite board 10 is spread over the top of the building composite board 10 without gaps, and the base material 15 is jointed on the upper surface of the building composite board 10 in a direction in which the longitudinal direction is orthogonal to the longitudinal direction of the building composite board 10. Joint 27 so as not to overlap with part 26
Are formed, and the finishing material 16 is arranged on the upper surface of the base material 15 so that the building composite board 10
Is firmly supported by the joists 18 and the cross members 19 constituting the floor support structure 17 and the joints 16 and 27 are arranged so as not to overlap with each other. Not only does it have sound insulation and heat resistance, but the sound and vibration of lower or upper floors
Through the building composite board 10 and the base material 1
5 are arranged in a direction orthogonal to their respective longitudinal directions, so that a structure that is strong against vibration and impact is formed as a whole, and the entire floor has a sound insulation effect. Also, in the ceiling structure 20 of this embodiment, the suspension member 22 attached to one of the rigidly mounted transverse member 19 and the suspending member receiving member 21 directly attached to the transverse member 19 has the edge supporting member. The ceiling finishing material 25 is attached via the ridge 23 and the edge material 24, and the vibration and the impact sound are not transmitted from the joist 18 directly to the ceiling finishing material 25 through the hanging tree 22. Is not transmitted to the lower floor, and similarly, the vibration and impact sound of the lower floor are not transmitted to the upper floor.

FIGS. 7 and 8 are views for explaining the floor structure of a building using the composite board for building according to the second embodiment of the present invention.
FIG. 7 is a partial sectional view of the building, and FIG. 8 is an enlarged sectional view of the floor structure of the building. Parts and members corresponding to the first embodiment are denoted by the same reference numerals.

The floor structure of the floor includes a concrete floor 33, a plurality of support members 32 disposed thereon at intervals of, for example, 350 to 400 mm, and a floor substrate 31 supported by the support member 32. Then, the composite board for building 10 is spread on the upper part of the floor substrate 31 similarly to the first embodiment, and the base material 15 is similarly spread on the upper surface of the composite board for building 10 so that the joint portions do not overlap. The finishing material 16 is disposed on the upper surface of the base material 15. The support member 32
A support 32a made of a material such as a hard rubber having vibration damping properties
A support bolt 32b protrudes upward from the upper part, and a receiving bracket 32c is screwed to the upper end side of the support bolt 32b so that the vertical position can be adjusted. In the support member 32, a support base 32a is disposed on the upper surface of the concrete floor 33, and a vertical position of a receiving bracket 32c attached to the supporting bolt 32b is adjusted, and the floor substrate 31 is horizontally positioned above the receiving bracket 32c. It is arranged so that it becomes. The floor substrate 31 is, for example, a particle board of about 20 to 40 mm formed in a rectangular shape, and is laid so that no gap is generated.

In the floor structure of a building having the above-described structure, a floor support structure 30 is constituted by a floor substrate 31 supported by a large number of support members 32 disposed on a concrete floor 33. Since the composite board 10, the base material 15, and the finishing material 16 are sequentially arranged, the building composite material 10
Not only does the gypsum board 11 have sound insulation and heat insulation properties, but also is supported on the concrete floor 33 via the support 32a of the support member 32 made of hard rubber or the like, so that vibration and impact noise are applied to the support 32a. Absorbed to prevent transmission to other floors.

In the above-described embodiment, an example is described in which the composite board 10 in which the plates 12 and 13 are bonded to both sides of the gypsum board 11 is used for the floor structure of the building. A composite board 10 'for a building in which a board member 12' is bonded to the same can also be used for a floor structure,
Furthermore, it can be used as a roof or wall material. Further, the building composite boards 10, 10 'are not limited to the dimensions of the embodiment as long as they are formed at least in standardized dimensions used for the building. Composite board for building 1
The reference numerals 0 and 10 'can also serve as a base material, and the finish material 16 may be directly disposed without the base material 15 of the embodiment.
