Description

[Detailed description of the invention] [Industrial application field] The present invention relates to soundproof flooring materials.

(Problems with conventional technology Oshiso) Conventionally, as a soundproof flooring material that prevents the propagation of solid sound due to impact to the flooring material, a cushioning layer such as a foam material is attached to the back side of the flooring material to provide a cushioning layer. ing.

In other words, due to the function of the buffer, even when an impact is applied to the surface of the flooring material, the deformation of the buffer increases the duration of the impact, resulting in a change in momentum, that is, a temporal change in impulse and impact force. Even if the integral value is constant, the peak value of the impact force and the natural frequency of the impact are reduced, the impact input energy to the board is reduced, and the sound and vibration caused by the impact are reduced.

However, in order to fully demonstrate its effect, it is desirable to position the buffer as close as possible to the point of impact where the buffer is applied, and based on this idea, the surface finishing material and the substrate A surface material with a buffer sandwiched between the two has been proposed.

Furthermore, in this configuration, when higher soundproofing properties are desired, it is preferable that the thickness of the buffer body sandwiched between the face materials be at least 2 cm or more.

However, if a buffer body having a thickness of 21 mm or more is sandwiched between the face materials, when actual processing is performed using a tenoner on the end face of the face material, the elasticity of the buffer body allows for a precise tenoner. It was not possible to set the thickness of the product, resulting in irregularly shaped products, and the actual fitting of the finished product was extremely inaccurate.

Therefore, actual processing was not performed on the end faces of the facing materials, but instead they were to be constructed in the form of butts.

However, since the end faces of the flooring materials are formed for butting purposes, during construction, 1. Misalignment occurs between adjacent flooring materials due to the difference in sinking due to the difference in load, and from that part This may cause peeling of the surface veneer, accumulation of dust, tripping, etc.

2. There is a problem that the amount of sinking is large, causing discomfort when walking.

[Means for Solving the Problems and Their Effects] The soundproof flooring material of the present invention was conceived with the following structure in order to solve the problems of the conventional cushioning materials as described above. In other words, in a soundproof floor material having a surface material sandwiching the floor body cushioning body A between the surface finishing material 1 and the substrate 2, the surface finishing material 1 and the substrate 2 have peripheral edges that protrude more than the floor body cushioning body A. The real part buffer B is attached to the lower surface of two adjacent sides of the protruding peripheral edge of the surface finishing material 1, and the real part buffer B is
The amount of sinking (x+
The thickness θ reaches the substrate 2 before reaching α), and the real part buffer B has the elasticity exhibited by the amount of sinking between the asymptotic contraction start point and the contraction end point /\ of the floor body buffer A. By devising the above-described structure, the present invention prevents misalignment from occurring when a heavy load is applied to the abutting portions of adjacent surface finishing materials 1, and also prevents the occurrence of squeaking sounds. It has been made possible.

[Explanation of Examples]

Examples of the present invention will be described below.

As shown in Fig. 1, the floor body cushioning body A is located between the surface finishing material 1 and the substrate 2, and the four peripheral edges of the surface finishing material 1 and the substrate 2 protrude beyond the four peripheral edges of the floor body cushioning body A. As in, it is pasted.

The surface finishing material 1 refers to a surface decoration 4 applied to the surface of a base material 3, and as the base material 3, plywood, fiberboard, metal plate, synthetic resin board, etc. are used. The surface decoration 4 applied to the base material 3 includes artificial veneer, natural wood veneer, decorative paper,
etc. and optionally painted as necessary,
Alternatively, an arbitrary pattern is formed directly on the base material by painting or printing.

The substrate 2 is made of plywood, fiberboard, LVL, laminated board, metal plate, synthetic resin board, etc., in the same way as the base material 3 in the surface finishing material l, and is suitable for the flooring material to be obtained. Any material and dimensions that can provide the necessary strength and thickness may be used.

A floor body buffer A is sandwiched between the surface finishing material 1 and the substrate 2.

Buffer A is synthetic resin foam, foam rubber, synthetic rubber,
Any non-woven fabric or other material may be used as long as it has a buffering capacity to prevent the propagation of solid sound due to impact on the floor surface.

The surface finishing material 1 and the substrate 2 have the same dimensions,
As shown in Fig. 4, the four circumferential edges of the surface finishing material 1 and the substrate 2 are attached so that they have the same width and protrude from the four circumferential edges of the floor body cushioning body A sandwiched between them. .

Of the four peripheral edges of the protrusion of the surface finishing material 1, the fruit cushioning members B are attached to the lower surfaces of two adjacent sides to form a fruit.

As shown in FIG. 5, the actual part formed by the real part buffer B is fitted between the surface finishing material 1 of the adjacent flooring material and the protruding part of the real part buffer B of the substrate 2 during construction, as shown in FIG. It is.

It is desirable that the width of the buffer body B forming the fruit is about twice as long as the protrusion of the surface finishing material 1 from the fruit buffer B. (FIG. 2) The real portion buffer B is provided with an adhesive layer 5 on its upper surface, and is adhered to the protruding lower surface of the surface finishing material 1.

At this time, if a release paper 6 is loaded on the part of the upper surface of the real buffer body B that protrudes from the surface finishing material l, the release paper 6 can be peeled off immediately before construction on the site and the adjacent flooring material 1 can be removed. can be adhered to the protruding lower surface of the facing material 1.

As described above, since the lower surfaces of the abutting portions of adjacent flooring materials are fixedly bonded by the real portion buffer B, it is possible to prevent misalignment between the flooring materials.

As the material of the real part buffer B, synthetic resin foam, foamed rubber, synthetic rubber, nonwoven fabric, and other known buffer materials can be used.

As shown in Fig. 5 ■■, the real part buffer B is compressed from the rapid contraction start point A (Fig. 6) in Fig. Suppose that we approach (Fig.).

Then, as shown in FIG. 5, the real part buffer B reaches the substrate 2 before the floor main body buffer A reaches the asymptotic contraction start point. At this time, the thickness of the real part buffer B is assumed to be θ.

From then on, the floor body cushioning body A sinks in accordance with the sinking of the real cushioning body B, and as shown in Figure 5 ■, the limit contraction point of the real cushioning body B is reached.
(Fig. 6) and the sinking ends. The thickness of the real buffer at this time is (θ').

Figure 6 is a graph of the situation in Figure 5, with curve A
indicates the original sinking amount of the floor body buffer A. In curve A, A is the rapid contraction start point, the mouth is the asymptotic contraction start point, and C is the contraction end point. In addition, (x+α) is the sinking amount of the floor body buffer A from the rapid contraction start point A to the asymptotic contraction start point, (
x+α+β) is the limit shrinkage amount of the floor body buffer A.

Curve B shows the original amount of sinking of real part buffer B. In curve B, a indicates the contraction start point and the contraction end point of real part buffer B. X is the limit sinking amount of the real buffer B.

Therefore, θ−θ′=X The relationship is

Further, the elasticity of the real part cushioning body B is required to be the elasticity exhibited between the asymptotic contraction start point and the contraction end point C of the floor body cushioning body A.

This is because if the elasticity of the real part cushioning body B is greater than the asymptotic contraction start point of the floor body cushioning body A, sinking of the floor body cushioning body A cannot be suppressed. In other words, the floor body cushioning body A is generally made of foam, and the floor body cushioning body B is generally made of foam.
If the thickness of the floor body buffer A is set to a thickness that reaches the substrate 2 after passing the asymptotic contraction start point, the floor body buffer A will sink too much to the asymptotic contraction start point. , misalignment between adjacent surface finishing materials 1 may also occur, causing discomfort when walking. However, the thickness of the protrusion buffer B may be such that it exceeds the asymptotic contraction start point and reaches the substrate 2 before reaching the contraction end point C.

〔Effect of the invention〕

The effects of the present invention can be summarized as follows.

■ By interposing the real part buffer B, there will be no misalignment between adjacent floor materials, which will prevent damage to the surface edges of the floor materials, accumulation of dust, tripping, etc.
You can solve problems caused by mistakes.

■ - Even under heavy loads, the propagation of solid sound due to impact can be prevented at the part where the flooring material butts, providing high soundproofing properties.
