Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a constrained type vibration damping floor member for direct sticking, which can be directly stuck on a concrete floor surface or the like to prevent shock propagation to the downstairs. . In particular, regarding the constrained type damping floor member in which the damping layer is restrained by the upper finishing material and the lower plate, by providing a groove on the back side 1b of this upper finishing material, it is possible to easily follow the irregularities of the concrete floor surface and It is intended to provide a stable wooden floor over a period of time.

(Prior Art) In recent years, there has been a great demand for cheap and hygienic wooden floors for cleaning the floors of condominiums, such as middle and high-rise apartments, by replacing them with carpets and tatami mats that easily cause mold and mites. .
However, the biggest drawback of wooden floors is that the living sounds of the inhabitants, that is, the sounds of dropping and moving pedestrians and objects are transmitted downstairs, which is extremely annoying.

(Problems to be solved by the invention) As a measure to cope with this, there are adopted construction methods such as floating floors, standing floors, etc. and double ceilings. It had to be made higher, which caused drawbacks such as higher construction costs. Therefore, a method to mitigate the floor impact sound by a direct attachment method that was applied directly to the concrete floor surface was considered. It has been proved that such a constrained type vibration damping floor member for direct application also has a very large floor impact sound absorbing effect.

However, the following points have also been desired in a constrained type damping floor member for direct attachment, which was conceived for the purpose of eliminating the above-mentioned drawbacks.
That is, it is general that the surface of the concrete floor surface is mortared by hand, so that the mortar surface inevitably causes unevenness, which greatly affects the finished surface after construction, and the actual joint part. Was conspicuous, and it was difficult to obtain an effective adhesion area between the floor material and the concrete floor surface.

On the other hand, in a constrained type damping floor material in which a damping layer is sandwiched, since the upper constraining layer and the lower constraining layer are necessarily arranged, the upper and lower constraining layers have the same strength. If it is not set to the same level and the moisture absorption and release rate is not the same, warping of the floor material is likely to occur, it takes time to insert the actual joint during construction, and the actual joint part is easily noticeable even after finishing Therefore, there was a drawback that it spoiled the aesthetics. Therefore, it has been desired to make it easier to follow the unevenness of the concrete floor surface, improve the efficiency of construction, and improve the beauty after construction.

(Means for Solving Problems) As a result of various test studies, the inventors of the present invention have confirmed that the above-mentioned drawbacks can be improved by the following method, and achieved the present invention.

In the present invention, the male and female actual joints 6 and 6 are respectively provided on the peripheral portions of the floor material in which the damping layer 2 is sandwiched between the wood finishing material 1 which is the upper constraining layer and the lower plate 3 which is the lower constraining layer.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view of a restraint type damping floor member for wood-based direct attachment, showing an example of the implementation of the present invention. FIG. 1A shows the upper constraining layer of the damping layer 2, in which the back surface 1b of the wood finishing material 1 is provided with the groove 4A having the depth of 2 mm, the groove width of 1 mm and the groove interval of 150 mm, and the damping layer 2 is plywood. And the lower plate 3, which is the lower constraining layer,
Further, it is formed of an unsteady adjusting material 5 which absorbs minute projections and the like on the concrete floor surface, and an actual joint portion 6 which joins the floor material to the peripheral edge portion of the floor material.

Fig. 1B shows a depth 1mm, groove width 1mm, groove spacing on the back surface 1b of the upper plate 1.
This is an example in which a groove 4 of 150 mm is provided and a damping layer 2 made of an air filled base material 2D with a crosslinked viscoelastic body is used.

In this figure, reference numeral 1 is a wood finishing material having a surface finish, which is a decorative veneer and plywood, or only a decorative veneer, or
Any wood-based material such as a laminated board and a hardboard in which a decorative veneer and a plywood or a decorative veneer are bonded together may be used.

The damping layer 2 is made of soft rubber, soft urethane, or a foam thereof, a polyethylene foam, a polystyrene foam, glass wool, a fibrous material such as glass wool, a liquid inclusion, a gas inclusion, a powder inclusion, or the like. It may be a composite, or a film and a laminate of these.

Preferably, as shown in FIG. 1 (B), a convex portion 2A filled with air and a concave portion 2B filled with a crosslinked viscoelastic substance 2D that cures at room temperature are alternately continuous to form an independent air chamber 2E. A vibration-damping layer 2 formed by forming a film base material 2C to be formed, and a crosslinked viscoelastic substance 2D is a main component mainly containing a telechelic polymer having two or more functional groups in one molecule. And a cross-linking viscoelastic substance obtained by curing reaction of a functional group of a pre-existing telechelic polymer with a curing agent having two or more functional groups in a molecule at room temperature.

The above-mentioned film base material 2C is arranged in a corrugated form with convex portions and concave portions alternately, and air is enclosed in the convex portions 2A to form an air chamber.
2E is formed, and the recess 2B is filled with the crosslinked viscoelastic substance 2D to form the damping layer 2 as a whole.

The top of the corrugated film base material 2C is joined to the wood finishing material 1, the bottom of the corrugated film base material 2C is joined to the lower plate 3, and the air chamber 2E is formed in the convex portion 2A enclosing air. It is formed.

Further, of course, it may be a composite of the laminate of the uneven sheet having the independent air chamber and the crosslinked viscoelastic material and the vibration damping layer. Reference numeral 3 is a lower plate which is a lower constraining layer of the vibration damping layer 2, and may be a plywood, a hard board, a plastic board, a metal plate, or a composite board of these. Reference numeral 2 is a damping layer provided at the joint between the floor material and the floor material of the present invention, and the uneven joint portions 6, 6 are formed at the joint portion. It is not limited to the structure. 5 is an elastic non-resorbable material that absorbs minute projections on the concrete floor surface, such as polyethylene foam, polystyrene foam, polypropylene foam,
Further, a foamed body of these mixtures, a foamed body made of a mixture with a filler, or various fibrous materials are suitable.

2 is a sectional perspective view of the present invention, and FIG. 2 is a groove 4A.
Shows a case in which it is formed vertically and horizontally on the back side 1b of the surface finish material 1 which is the upper plate.

FIGS. 3A and 3B show the cross-sectional shape when the construction is performed on the concrete floor surface 7, and FIG. 3A shows the groove 4B shown in FIG. 2A, which is an example of the present invention, on the back surface of the upper plate 1. FIG. 3B is a cross-sectional view of what is vertically and horizontally formed in 1a and is laid on the concrete floor surface 7 through the damping layer 2, the lower plate 3 and the undyed absorbent material 5. FIG. Fig. 3 shows a cross-sectional view when the swing material is applied on the uneven concrete floor surface 7. In Fig. 3A, the groove 4B is formed on the surface 1a of the upper plate 1, so that the flexibility of the floor material is increased. In addition, the unevenness of the concrete floor surface 7 is sufficiently followed, but with the conventional constrained type vibration damping floor for direct pasting shown in FIG. 3B, since the flexibility of the floor material is low, An unsuccessful non-adhesive portion 8 is formed between them, which is considered to be the source of floor squeaking and floor squeaking noise. As shown in Fig. 3A, in the present invention It is intended to eliminate these drawbacks.

Further, as shown in FIG. 4, the wooden floor vibration damping flooring material for direct attachment of the present invention is constructed by laminating the flooring material of the next row by shifting the length of 1/4 to 1/2 in the longitudinal direction. Desirably, it is preferable to bond them by shifting them by 1/2 or 1/3, because the joints are less noticeable and the finish is also beautiful.

That is, when a conventional damping floor member for direct pasting is pasted onto a concrete floor surface, uneven bonding of the base slab or warping of the floor material causes push-up of the actual joining portion of the floor material in the short side direction. , The actual joint part was raised, and the finished state was bad,
In addition, a defective adhesion portion 8 between the concrete floor surface 7 and the floor material.
However, by practicing the present invention, it is possible to give the floor material flexibility and eliminate the push-up of the actual joint. In addition, by increasing the flexibility of the flooring material, there is an advantage that the actual joining of the flooring material in the long side direction is facilitated and the construction time can be shortened.

By carrying out as described above, the constrained type vibration damping floor material of the present invention can exhibit extremely flexibility, and therefore it is possible to follow the irregularities of the concrete floor surface. Efficiency goes up and we can control sledge of wooden floor,
In addition, it is possible to provide a direct-adhesion floor with a good finish.

In addition, the lower plate 3 which is the lower constraining layer absorbs and releases moisture from the concrete floor surface, and the wood finishing material 1 which is the upper constraining layer.
However, the expansion and contraction of the floor material caused by being affected by the humidity in the air is absorbed by reducing the expansion allowance that is involved in the expansion and contraction of the floor material by providing the upper plate 1 and the groove 4A in the back plate 1b. As a result, the stability of the flooring material that lasts for a long time also increases.

Here, on the back surface 1b of the wood surface finishing material 1 of the upper restraint layer,
Groove width 1 to 3 at right angles to the longitudinal direction or at intervals of 30 to 300 mm vertically and horizontally
The purpose of providing a groove 4A of mm to secure the thickness of the wood surface finishing material 1 to be 3 mm or more is to give flexibility to the wood surface finishing material 1,
Not only to make the floor material easily follow the concrete floor surface, but also to suppress the warpage of the floor material.If the distance between the groove 4A and the groove 4A is within 30 mm, the surface finish material when a large point load is applied. 1 has a risk of breaking, and it is unsuitable to follow the unevenness of the concrete floor surface when it is 300 mm or more.

Also, the reason for securing the plate thickness of the wood surface finishing material 1 to be 3 mm or more is that the thickness is 3 mm or more so that it does not break even when receiving a large point load, and the reason for making the groove width 1 to 3 mm is 1 mm or less This is because there is a lack of followability and there is a risk of damage when the thickness is 3 mm or more.

The wooden restraint type vibration damping floor member satisfying the above conditions can effectively mitigate the floor impact sound to the downstairs, and can eliminate the conventional defects in the workability and the finished state.

However, the present invention exerts its effect by forming the groove 4 on the back surface 1b of the upper plate 1, and the present invention is not limited depending on the shape of the groove.
