Description

[Detailed Description of the Invention] [Industrial field of application] This invention is a wooden sound insulation for direct attachment, which has a structure that facilitates quick floor covering construction and provides suitable wooden floor material stable support and sound insulation. It's about the floor.

[Prior Art] Conventionally, a direct-adhesion flooring material for a house is usually composed of a wooden part made of a combination of plywood and a sound-absorbing cushioning material at the bottom, and the wooden part is a combination of plywood and a vibration-proof material. Many structural improvements have been made, and various shapes and functional materials are used for the cushioning material at the bottom, but epoxy resin adhesive is mainly used as the fixing method to the floor base. ,
This is a structure for floor covering with epoxy resin or other rubber adhesive applied over the entire surface.

[Problems to be Solved by the Invention] Since all of the above conventional direct-adhesion floor materials are configured to be fixed with an adhesive, the floor-laying process becomes very complicated,
It requires a considerable amount of skill to set and spends a lot of time on the bonding process with the adhesive, and in addition to solving the problems of construction inefficiency and high cost, floor stripping for remodeling especially due to diversification of flooring Due to the difficulty of construction and re-construction, it is necessary to respond to the signs that the need for renovation of wooden floors will be highlighted.

[Means for Solving the Problems] In order to solve the above problems, an effective structure is required. That is, in the case of fixing the adhesive on the floor base as in the past,
It requires a considerable amount of skill such as application of adhesive, timing of adhesion, and assembly of floor material on the adhesive, but such skill is unnecessary, and it is always possible to obtain uniformity. The construction, the construction speed is not restricted by the construction factors, the speed can be speeded up including the setup, and uniform fixing without construction unevenness is always obtained. The total cost of construction materials and man-hours is below the current level. There is no problem in terms of safety and hygiene during construction, and it is easy to install and remove when directly renovating a floor.

In consideration of each of the above problems, in order to solve the above problems, the present invention has devised a wood soundproof floor for direct application, which can be mechanically fixed without an adhesive on the floor covering of wood flooring. .

That is, this mechanical fixing is to form anchoring tapes for fixing on the back surface of the wooden floor material and both surfaces on the floor base. This anchor tape has a required width (an appropriate dimensional width is used depending on the setting member and other conditions,
It is not necessary to form the entire surface, and it is generally formed with a width of about 20 to 40 mm at appropriate intervals. ) Anchor tape with a large number of anchor protrusions with hook-shaped tips of various adaptive shapes (harpoon, anchor type, etc.) that effectively adheres the adhered medium to the surface of the plastic strip is used. Then, in advance, secure this anchor tape to the back surface of the wooden flooring material with a required space and firmly fix it with resin adhesive, plastic adhesive, etc. Fix with a resin adhesive, a plastic adhesive, a pressure sensitive adhesive sheet, etc. at intervals.

Such a fixed form can be fixed in advance at a factory or the like on the back surface of the wooden floor construction unit floor, and,
It can be easily set in advance on the floor base of the construction site before assembling the unit floor material for construction, and at the time of floor covering construction, the fiber composite cushioning material is interposed between the wooden floor material and the floor base. Sufficient mechanical fixation can be obtained only by performing the above.

That is, a wooden soundproof floor for direct application is very easily constructed by interposing a fiber composite cushioning material in the form of a thick nonwoven fabric or a flexible woven fabric as a soundproof fixing medium.

The non-woven fabric form is preferably a thick non-woven fabric, which is made of long fibers having excellent fixability and reinforced by quilting from the back surface. Further, a non-woven fabric in which two layers of non-woven fabric having a size of about 1 mm to 2 mm are laminated and quilted integrally may be used. In particular, as the flexible woven fabric form, a flexible woven fabric form woven from a gathered yarn having excellent fixability and less twisting is preferable, and a woven fabric sewn with a required thickness and the like can also be used. Other flexible pile fabric systems can also be used.

The thickness of the above-mentioned fibrous material depends on desired conditions such as cushioning property, supporting property, stability, etc., in consideration of the cooperation with the elastomer,
It is selected appropriately. The theory and the thickness of the elastomer are also appropriately selected according to the desired conditions.

The above-mentioned fiber composite cushioning material composed of a composite material of a fiber material and an elastomer is a fiber material having a thickness sufficiently fixed by anchor projections, a flat elastomer molded sheet, a groove-shaped elastomer molded sheet, and a projection-shaped elastomer molded sheet. It is formed by integrally adhering a cushioning material of various elastomers in a solid or foamed form such as a sheet.

Therefore, various forms are used, and the following various forms are conceivable.

For example, as the a and b forms, on both front and back surfaces (a form) of a flat foamed elastomer molded sheet or a solid elastomer molded sheet, or on one side (b form), a thick nonwoven fabric having a thickness of 1.0 mm or more or a flexible A fiber composite cushioning material is formed by integrally bonding fiber materials such as woven cloth. In this example, in the case of the fiber composite cushioning material in which the fiber material is bonded and integrated on one side, the elastomer molded sheet side is contacted to form two layers, and therefore the thickness of the elastomer is appropriately adjusted. Adjusted.

As the c form, a thick nonwoven fabric of 1.0 mm or more in thickness or a soft woven fabric is bonded and integrated on both front and back surfaces of a foamed elastomer molded sheet or a solid elastomer molded sheet on which uneven patterns such as grooves and protrusions are formed. To form a fiber composite cushioning material.

As the d form, a thickness of 1.0 mm on the flat side of the merged foamed elastomer molded sheet or the merged solid elastomer molded sheet on which the merged concavo-convex pattern such as a groove shape or a protrusion shape is formed.
The above thick non-woven fabric or flexible woven fabric is adhered and integrated to form a fiber composite cushioning material. Two layers of this fiber composite cushioning material are used, and the concavo-convex side is merged to form one elastomer layer. To intervene. The merging property in this example means that, in the case of the protrusion type, the protrusions are combined in a single layer by combining the protrusions within the protrusion space in which the free space can be obtained. The protrusions are aligned within the groove width where the free space ratio is increased and the layers are merged into one layer.

The material of the anchor tape for fixing the fiber composite cushioning material is appropriately selected and used from high toughness thermoplastic and thermosetting plastics excellent in mechanical, physical, chemical and thermal properties. It is preferable that the hardness is high and the toughness index having a large strength and elongation is large.

[Function] The wooden soundproof floor for direct attachment of the present invention is different from the conventional structure in which an elastomeric soundproof cushioning material is applied to the entire surface of the floor base with an adhesive, unlike the conventional structure. And place anchor tape beforehand on the floor base,
Since the sound-absorbing cushioning material of the elastomer is integrated with the fiber material because it is fixed by interposing the fixing medium of the fiber material, the elastomer is sufficiently reinforced by the fiber material, which is a drawback of the elastomer. Not only the creep property is suppressed, but the fine-wave dynamic cushioning property is obtained by the synergistic effect of the favorable support property and flexibility of the impact-damping fiber material, the favorable cushioning property of the elastomer, and the soundproofing property. As compared with the conventional direct adhesive setting, more stable stable support and soundproofing effect of the wooden flooring material can be obtained, and in particular, a very stable and flexible walking feeling can be obtained. Further, the elastomeric soundproofing cushioning material is supported by a fiber-based fixing medium without being directly fixed to the floor base by an adhesive, and thus has great freedom and excellent dynamic action and excellent performance. It is soundproof and prevents breakage tendency during repeated dynamic action.

[Embodiment] Next, the construction of the wood soundproof floor for direct attachment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing an example of a construction unit flooring material used in this invention which constitutes a floor covering of wooden flooring material, FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. Is a schematic vertical cross-sectional view of a wood soundproof floor for direct pasting of the present invention showing another example of the construction unit floor material, and this example shows a divided unit floor material obtained by dividing the construction unit floor material of FIG. 1 into four. The figure shows an example of a construction unit flooring with four pieces joined together. The construction unit flooring is usually 300 mm wide, and lengths of 900 mm, 1200 mm, 1800 mm, etc. are appropriately used. One that is constructed as a piece, other 300 mm
The width is divided into 3 parts, 4 parts, etc. as needed, and the divided unit floor materials are combined and used as a construction unit floor material. It is preferable to fit and fix with an adhesive to form the floor width of the construction unit. Anchor tapes are fixed at appropriate intervals on the back surface of the construction unit flooring formed in these construction unit widths, and also on the floor base such as concrete, the anchor tapes are fixed at appropriate intervals, A fiber composite cushioning material is interposed as a soundproof fixing medium between the two anchor tapes to form a wooden soundproof floor for direct attachment.

The vertical cross-section of Fig. 3 has a step to clearly show the anchor tape, but the anchor tape is actually a thin sheet of about 0.5 mm, which is less than 1 mm of hard material, and the protrusion is flexible. The flexible fiber composite cushioning material, which is inserted and fixed in the fiber composite cushioning material composed of a flexible elastomer and a flexible fiber material, is easily deformed and averaged to form a uniform linear support state.

An example of the construction of the wooden soundproof floor for direct attachment of this invention is
As shown in the longitudinal sectional view of the figure, the anchor tape 7 of FIG. 4 is fixed to the back surface of the construction unit floor material LI with an adhesive 6 at an appropriate interval, and the anchor tape 7 is also attached to the floor base SF at an appropriate interval. 7
Is fixed with an adhesive 6. Anchor tape 7 for both
By interposing a fiber composite cushioning material FCCM between them and fixing them under pressure, a wood soundproof floor for direct attachment is constructed.

This fiber composite cushioning material FCCM is a projection AP of the anchor tape 7.
Fiber material (upper fiber material 8, lower fiber material 9) such as thick non-woven fabric or flexible woven fabric with a thickness of 1 mm or more, which is sufficiently fixed with, a flat elastomer molded sheet, and a groove shape for forming an uneven pattern It is formed by integrally bonding the cushioning material of various solid or foamed elastomer molded bodies 10 such as the elastomer molded sheet or the protruding elastomer molded sheet. The fiber composite cushioning material formed of the upper and lower fiber materials 8 and 9 and the elastomer molded body 10 is used in various forms depending on the shape of the elastomer molded body 10.

The form is the form a mentioned in the section of the means for solving the problems, that is, the upper fibrous material 8 on both front and back surfaces of the elastomer molded body 10 such as a flat foamed elastomer molded sheet or a solid elastomer molded sheet. In the form b, two fiber composite cushioning materials in which the upper fiber material 8 and the lower fiber material 9 are integrally bonded to one surface of the elastomer molded body 10 are integrally formed. FCCM is formed, the elastomer molded body 10 side is contacted, and is interposed between the wooden floor material and the floor base.

The c-type is a cushioning material and various upper and lower fibrous materials 8 for various types of solid or foamed elastomer molded bodies 10 in which a groove-shaped or protrusion-shaped uneven pattern is formed on one side of the sheet. , 9 are integrally bonded to each other.

As shown in the example of FIG. 5, the d-form is a method of separating an elastomer molded body having an uneven pattern into two and combining them into one. One of the merging elastomer moldings 11 such as the two merging foam elastomer molding sheets or the two merging solid elastomer moldings having the uneven pattern is provided with the upper fiber material 8 on the plane side and the other one. For each piece, the lower fiber material 9 is bonded and integrated on the plane side to form a fiber composite cushioning material, and the two concavo-convex pattern sides of the fiber composite cushioning material FCCM are combined to form one elastomer layer. To intervene.

The merged concavo-convex portions of the mergeable elastomer molded body are merged so as to form an appropriate free space so that the elastomer can be freely buffered. This interval is appropriately adjusted according to the demands for cushioning property, supportability and the like.

That is, the meaning of the above-mentioned merging property is to combine the protrusions so that the protrusions are overlapped with each other so that a free space is formed between the protrusions.

FIG. 5 is a longitudinal sectional view of a merging fiber composite cushioning material, 8 is the above fiber material, 9 is a lower fiber material, 11 is a merging elastomer molded body, and this example is a groove-shaped uneven pattern. As the groove shape, a vertical groove shape, a horizontal groove shape, a vertical and horizontal double groove shape, or the like is appropriately selected. Further, spherical projections and other projections are also formed so as to be similarly combined.

These fiber composite cushioning materials described above can be strongly bonded and integrated at the factory during molding of the elastomer molded body or during the process thereof, and when the floor is laid at the site, it is interposed between the wooden floor material and the floor base material. It can be pressed and fixed by just pressing.

[Advantage of the Invention] The wooden soundproof floor for direct pasting exhibits the function as in the above-mentioned action because of the configuration as described above, and since the flooring is performed by mechanical fixing, It has the following characteristics.

There is no danger of fire or hygiene.

Unlike conventional floor coverings using adhesive, it can be performed continuously, not partially or intermittently, so that all steps are sped up, and construction time and construction cost are greatly reduced.

Since the wooden floor material is fixed simply by pressing the fiber composite cushioning material to the anchor tape, the elastomeric soundproofing material is adhesively fixed to the wooden floor material and epoxy resin is adhered to the floor base material as in the past. As in the case of adhesive fixing with agents, there is no risk of the elastomer being damaged by repeated cushioning operations of the elastomer due to peeling adhesion from the wooden flooring material or adhesion with the epoxy resin, and good cushioning properties for a long time Is secured.

Since the wood flooring is fixed by mechanically fixing the fiber composite cushioning material, suitable stability is achieved due to the effect of integrating both properties of the resilient cushioning property of the elastomer and the flexible support of the fiber sheet of the fixing medium. You can get the soundproof floor with the floor feeling.

It is easy to remove when remodeling a wooden soundproof floor and it is easy to construct a new floor.

Due to mechanical fixation by pressure welding with fiber composite cushioning material,
There is no breakage of the bonded portion due to an extreme difference in physical properties such as adhesion between a soft body and a rigid body as in the conventional case, and stable fixing can be secured for a long period of time.

Since the anchor tape is a hard material, the floor base such as wood flooring and concrete is firmly fixed to the hard epoxy resin, so the anchor tape secures a stable and firm fixation, and the anchor projections make it possible to use a fiber composite material. The cushioning material guarantees stable fixation for a long period of time.
