Abstract

PURPOSE:To avoid the generation of problems such as the generation of the sounds caused by the curing of adhesives by sticking the fitting convex section of a hard floor material to the fitting recessed section of the floor material adjacent to it and laying them on the cushion layer on a floor backing. CONSTITUTION:A fitting convex section 2 and fitting recessed section 3 are formed in a part of the peripheral section of the hard floor material 1 comprising ligneous base plates 7 and 7, in the recess sections of which urethane rubbers are charged, and a decorative plate layered on the upper section of the ligneous base plate 1 and the rest of the periphery respectively. On the cushion layer 8 on a floor backing 4, the fitting convex section 2 of the hard floor material 1 is laid being stuck to the fitting recessed section 3 of the floor material adjacent to the fitting convex section 2 through adhesives 5 of low viscosity. The adhesives 5 of low viscosity must be applied without unevenness so that the air tightness of a joint section may not be spoiled, and so that the adhesive film after sticking may have flexibility. By this constitution, the generation of problems caused by the curing of the adhesives and the generation of the sounds caused by stepping can be avoided.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a connection structure for hard flooring materials such as wooden flooring materials laid on a subfloor surface, and more specifically, to improve the soundproofing properties of the connection points. It is related to the technology to

[Prior Art] Conventionally, when installing and connecting wood-based hard flooring materials on the subfloor, a mating convex portion and a mating concave portion are connected using a wood bond [CH-1].
8 Konishi Co., Ltd. 1 is applied and inserted and connected.

[Problem to be Solved by the Invention 1] However, such a woodworking bond (vinyl acetate type) has a high viscosity of so,ooo to 60°000 centipoise, and is likely to cause uneven application (and its insertion). Since the airtightness of the connection points was compromised and the adhesive hardened after installation, there were problems such as cracking of the hardened adhesive when a load was applied and the generation of stomping noises. In the case of having 27217 layers on the back side, the hard flooring material 1 sinks and the above-mentioned problem becomes more noticeable.

The present invention was made in view of such problems,
The purpose is to provide a connection structure for hard flooring materials that can improve the adhesive applicability, avoid loss of airtightness, and prevent stomping.

[Means for Solving the Problems] In the hard flooring connection structure of the present invention, a fitting protrusion 2 is formed at -aS of the hard flooring 1, and a fitting recess 3 is formed at the other lII' end. , the fitting convex part 2 of the hard flooring material 1 laid on the floor substrate 4 is inserted and connected to the fitting concave part 3 of the adjacent material through a low viscosity adhesive 5. be.

[Function 1] In this way, the fitting convex part 2 of the hard flooring material 1 laid on the floor base 4 is applied to the fitting concave part 3 of the adjacent one with a low viscosity adhesive 5.
By inserting and connecting through the adhesive, the adhesive 5 with a low viscosity can be applied evenly (evenly), the airtightness of the connection part is not impaired, and the adhesive 5 with a low clay content makes it possible to apply the adhesive 5 evenly. This greatly reduces the occurrence of curing afterwards, avoids problems associated with curing of the adhesive, and also avoids the occurrence of stomping noises.

[Example] Embodiments of the present invention will be described in detail below based on the drawings.

A wooden decorative board 6, such as a veneer (sliced veneer) made by thinly slicing wood and having wood grains, is laminated on a wooden substrate 7, and the wooden substrate 7 is made of plywood, and the plywood is 3-ply, 5-ply, and 7-ply. etc. are used. Such hard flooring material 1 is formed into a rectangular shape, for example, as shown in FIG. The 7flfl recess is filled with urethane rubber,
A hard flooring material 1 is constructed as a single piece of wooden soundproofing flooring material. A fitting convex portion 2 is formed in a part of the local part of the hard flooring material 1, and a fitting recess 3 is formed in the remaining local part. The shape and form of this hard flooring material 1 can be modified in various designs. Then, the hard flooring material 1 is laid and fixed on a subfloor 4, and the fitting protrusion 2 is fitted into the fitting recess 3 with a low viscosity adhesive 5 interposed therebetween, thereby establishing the connection. .

In this way, the hard flooring material 1 is covered with cushioning debris 8 on the subfloor 4.
The hard floor material 1 is firmly fixed with an adhesive or the like and laid, and the fitting protrusion 2 of the hard flooring material 1 is inserted into the fitting concave portion 3 of the adjacent hard flooring material 1 with a low viscosity adhesive 5 interposed therebetween. The adhesive 5 is a soft resin such as an ethylene vinyl acetate copolymer resin with a non-volatile content (NV) of 56% manufactured by Funishi Co., Ltd.
A product with a product number such as Woodypfpond MT95 is used, and its viscosity is reduced to 15,000 to 20,000 centiboise.

In this way, by using the adhesive 5 with low viscosity, uneven application of the adhesive 5 to the fitting recess 3 is eliminated, and the fitting recess 3 is
It can be applied evenly throughout the interior without compromising the airtightness of the connection area, and because it is an adhesive, the coating after hardening after installation is flexible, eliminating problems associated with hardening of the adhesive. avoid
This also avoids the occurrence of stomping noises.

[Effects of the Invention] In short, the present invention provides a method of fitting [! Since the two parts are inserted and connected through a low viscosity adhesive, the low viscosity adhesive can be applied uniformly, easily and quickly, and the airtightness of the joint is not compromised. Low viscosity adhesive number,
The coating after application is flexible, which has the advantage of avoiding problems associated with hardening of the adhesive and also avoiding the occurrence of stomping noises.
