Abstract

PROBLEM TO BE SOLVED: To carry out the execution of works efficiently by adhering and laminating throw-board plywood on a foundation panel by a pressure sensitive adhesive double-coated tape while laminating a flooring material on the throw- board plywood. SOLUTION: Foundation panels 1, in which support legs 2 are fixed onto undersides and which consist of particle boards, are arranged on the top face of a concrete slab 9, in which the cord of an OA equipment is wired on a surface. Long-sized pressure sensitive adhesive double-coated tapes 3 are laminated on the top faces of the arranged foundation panels 1 at intervals so as to be extended over two or more of the foundation panels 1. A throw-board plywood 4 composed of veneer boards is bonded on the top faces of the double-coated adhesive tapes 3. Accordingly, since the foundation panels 1 and the throw-board plywood 4 are laminated without using nails, wirings, the foundation panels 1, and the throw-board plywood 4 can be executed efficiently without being damaged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-floor construction method for making a floor of a building such as a condominium, a public housing, an office or the like a double floor.

[0002]

2. Description of the Related Art Double-floor floors have been adopted for floors of condominiums, public housing, offices, etc. for the purpose of sound insulation, heat insulation, and wiring for OA equipment. The basic structure of such a double floor is, for example, as shown in FIG. 3, a base panel 1 composed of a particle board or the like on a concrete slab floor 9 via a vibration-proof rubber 21 and support legs 2 such as support bolts.
Is installed in a floating floor state, a waste board plywood 4 such as a veneer board is fixed by striking nails 10 on the base panel 1, and a floor finish material 8 is laminated on the waste board plywood 4 (for example, , JP-A-5-059807).

[0003]

According to the conventional construction method, since the waste plywood is fixed to the base panel by nailing, when the nail is long, it sticks out from the lower surface of the base panel and There was a case where the cords that were wired between the panel and the concrete floor were pierced, which could cause electric leakage. Further, there is also a problem that it is necessary to hit a large number of nails and the construction efficiency is reduced.

Furthermore, when a waste plywood is placed on the base panel,
Since it is not possible to know the position of the joint between the base panels, for example, nails may be driven into the supporting bolts or the metal frame material framing the base panel, which may damage the base panel or waste plywood, or There was also the problem that the head would stick out and the finish would be poor.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above conventional problems and to provide a double floor construction method capable of performing construction efficiently without fear of damaging wirings, base panels, and waste plywood. .

[0006]

A double floor construction method of the present invention is a double floor construction method in which a waste plywood is laminated on a base panel and a floor finish material is laminated on the waste plywood. It is characterized in that it is laminated with a discarding board and a plywood by a double-sided adhesive tape.

The double-sided pressure-sensitive adhesive tape used in the present invention has a woven or non-woven fabric, paper or the like as a base material, and an adhesive layer provided on both surfaces thereof, or one without a base material, that is, a release paper. It may be transferred by forming a pressure-sensitive adhesive layer on the release treated surface and bonding the pressure-sensitive adhesive layer to a base panel or a waste plywood. The pressure-sensitive adhesive is not particularly limited, and examples thereof include acrylic, rubber-based and silicone-based pressure-sensitive adhesives that are commonly used as pressure-sensitive adhesive tapes.

In the double-sided pressure-sensitive adhesive tape, when a foam is used as a base material, it has excellent heat insulating properties and soundproofing properties, and is well adapted to the uneven parts of the base panel and the waste plywood to improve the adhesiveness.
A smooth floor surface can be formed. The material of the foam is not particularly limited as long as it has flexibility and elasticity, and typical examples thereof include polyethylene and polyurethane. Further, by using the double-sided adhesive tape of the plastic film base material, it is possible to effectively prevent invasion of moisture, cold air and the like.

As a specific method for adhering the base panel and the waste plywood, the double-sided adhesive tape may be first attached to either the base panel or the waste plywood, and the area of attachment of the double-sided adhesive tape May be the entire bonding surface or may be partial such as stripes. Further, after the release paper is peeled off, water can be sprayed on the adhesive surface by spraying a spray or the like, whereby a fine position adjustment can be performed.

(Operation) A double floor construction method of the present invention is a double floor construction method in which a waste plywood is laminated on a base panel and a floor finishing material is laminated on the waste plywood. Since it is attached with double-sided adhesive tape, it is not necessary to hit nails, and since nails are not used, wirings, base panels, and waste plywood are not damaged. Furthermore, it can be constructed efficiently.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a double floor construction method of the present invention will be described with reference to the drawings. (Embodiment) FIG. 1 is a perspective view showing an embodiment of the double floor construction method of the present invention. Base panels 1 and 1 ′ made of particle boards having support legs 2 fixed to the lower surface are arranged on a surface of a concrete slab 9 on which the cords of OA equipment are wired. Lined base panels 1, 1'2 on top
The long double-sided pressure-sensitive adhesive tapes 3, 3 ', 3''are attached so as to cover more than one sheet and at appropriate intervals. When the plywood 4 which is the waste plywood 4 is placed on the double-sided adhesive tapes 3, 3 ′, 3 ″, the waste plywood 4 is adhered to the base panels 1, 1 ′.

FIG. 2 shows a cross-sectional view of the double-sided adhesive tape 3 of FIG. 1, in which acrylic adhesive layers 6 and 61 are provided on both surfaces of a crosslinked polyethylene foam 5 (thickness 1 mm), and one adhesive layer 61 is provided. The release paper 7 is laminated and wound in a roll shape with the release paper 7 on the outside. Double-sided adhesive tape 3 above
To attach the to the base panel 1, double-sided adhesive tape 3
From the roll-shaped roll (not shown) and release paper 7
The pressure-sensitive adhesive layer 6 without adhesive was attached to the base panel 1, and then the release paper 7 was peeled and removed, and the waste plywood 4 was attached to the exposed adhesive layer 61.

(Comparative Example) The construction was carried out in the same manner as in the example except that the double-sided adhesive tape was not used and the scrap plywood was fixed to the base panel by a conventional nailing method.

Performance Evaluation The construction conditions of the above Examples and Comparative Examples were evaluated for the items in Table 1, and the results are summarized in Table 1.

[0015]

[Table 1]

As shown in Table 1, in the construction method using the double-sided adhesive tape of the example, the fixing force of the plywood plywood to the base panel and the working time have the performance of nailing, and wiring cords under the floor and There was no damage to the base panel and the waste plywood.

[0017]

According to the double floor construction method of the present invention, since the base panel and the waste board plywood are attached by the double-sided adhesive tape, it is not necessary to hit nails, and since the nails are not used, wirings and base panels, The plywood will not be damaged. And it can be constructed efficiently.
