Description

[Detailed description of the invention] [Field of application of the invention] This invention relates to plywood flooring used in houses and the like.

[Prior Art] Conventionally, building materials having male and female cores that fit into each other around the periphery of the board have been widely used, and most flooring materials in particular have a structure with cores. It is no exaggeration.

[Problems to be solved with the invention] However, the size of the male fruit of conventional flooring materials is slightly smaller than that of the female fruit in consideration of ease of construction, which makes it easier to fit the flooring materials together. Ta.

Therefore, when an external force is applied from the top surface of the mating part, the mating part makes a squeak noise due to rubbing (commonly known as floor noise).
This was likely to occur and was unpleasant.

Therefore, methods such as injecting adhesive or caulking material into the mating part to stop the movement of the mating part and prevent the occurrence of floor noise have been taken, but the above-mentioned problems occur after the floor material is installed. The treatment was a very time-consuming task.

[Means for solving the problem] This invention was made to solve the above problem, and its structure consists of a plywood flooring material with male and female fruits on the periphery. In the case of plywood flooring in which the male fruit and the female fruit are formed at the position where the flexible sheet-like material interposed between the veneers constituting the plywood comes into contact with each other when the male fruit and female fruit are fitted together. Related.

Hereinafter, this invention will be explained in detail with reference to the drawings which are examples.

FIG. 1 is a perspective view showing an example of a plywood flooring material used in an embodiment of this invention, and FIG. 2 is a sectional view showing a fitted state of the flooring material according to an embodiment of this invention.

The plywood is composed of a commonly used veneer 3 and a flexible sheet-like material 4.

The veneer 3 is a veneer obtained by peeling South Sea wood such as lauan, domestic wood such as oak, or North American or Canadian wood such as pine using a rotary lace or slicer.

The flexible sheet material 4 has a thickness of 0.5 to 2.0
It is a flexible rubber sheet, plastic sheet made of vinyl chloride resin, polyethylene resin, etc., and is about mm in size.

When the above-mentioned flexible sheet-like material 4 is incorporated between the veneers 3 as plywood, when cutting the side surface of the plywood to form the fruit, at least a portion of the upper and lower surfaces of the male fruit 1 and the female fruit 2 are The flexible sheet-like material 4 is glued in such a way that it is sandwiched between the exposed positions, and when the male fruit 1 and the female fruit 2 are fitted together, the flexible sheet-like material 4
are the positions where they touch each other.

As the adhesive for bonding the veneer 3 and the sheet material 4, thermosetting resin adhesives such as urethane resin, acrylic resin, ethylene-vinyl acetate copolymer resin, melamine resin, and phenol resin are used.

In the case of this example, rubber sheets 4 with a thickness of 1.0 mm are bonded to the upper and lower surfaces of the third veneer 3, which is the center of the 5-ply plywood with a thickness of 12 mm, using thermosetting urethane resin adhesive. The real fruit is formed on the upper and lower surfaces of the male fruit 1 and the female fruit 2 at positions where the rubber sheet 4 is exposed to a thickness of about 0.3 mm on the fruit surface by bonding with heat and pressure using an agent. In addition, the thickness of the plywood surface is
A 0.3mm cherry blossom decorative veneer 5 is pasted.

[Function] In this invention, a flexible sheet-like material is placed at the part where the mating male fruit and female fruit come into contact with each other, so that it will remain flexible even if an external force is applied to the mating part and rubbing occurs. This is to prevent squeaks from occurring by absorbing the friction with the soft sheet-like material.

[Effects of the invention] As mentioned above, the plywood flooring material of this invention has a flexible sheet-like material arranged in the part where the mating male and female fruit come in contact with each other, so that the mating part Even if external force acts on the floor and causes rubbing, the flexible sheet-like material absorbs the rubbing and has the effect of preventing floor noise.

Claims (1)

[Scope of utility model registration request] In a plywood flooring material having male fruit 1 and male fruit 2 that fit into the peripheral part, when the male fruit 1 and female fruit 2 are fitted together, it is interposed between the veneers 3 that make up the plywood. A plywood flooring material characterized in that male fruit 1 and female fruit 2 are formed at positions where flexible sheet-like materials 4 come into contact with each other.
