Description

Wood flooring structure which is made of elastic soundabsorbing materials}

The present invention relates to a wood floor structure using an elastic sound absorbing material, and to a wood floor structure using an elastic sound absorbing material to improve the elasticity, sound absorption and shock absorption function of the wood flooring while reducing the amount of wood panels installed on the wood floor. will be.

In general, prefabricated floorboards, such as classrooms, corridors, gymnasiums, and floors of apartment buildings, are more environmentally friendly than other materials, efficiently absorb shocks and vibrations, and provide a visually soft and comfortable feel. As it is constructed, it is mainly used as floor finishing material.

The existing floor structure for installing wood floor is divided into three categories.

First, the adhesive is applied to the front surface of the formed lower base surface, and the floorboard is attached on the front surface. This structure has good adhesion between the floor and the floor, but various noises and impact sounds generated from the floorboard are filtered without filtration. In addition to being delivered as it is, when the lower structure is a yoke, joist structure there is a phenomenon that a space is formed inside the expansion to the resonance sound.

At present, about 50% of domestic floor constructions use such structures, and in Europe, about 40% use such structures.

In addition, when hard adhesive is used, the flooring of wood, such as plywood flooring (aka plywood flooring), cannot be used because the adhesive does not withstand the expansion and contraction of wood.

In addition, if you want to remove the old floor after long term use, it is difficult to dismantle due to the hard adhesive applied to the front of the floor, and if the construction is performed with less moisture on the foundation floor, the adhesive will not harden and immediately If it expands due to influence and the smoothness of the floor is not good, a squeaking sound is generated, so it is necessary to carefully examine the site conditions before construction.

Secondly, the elastic foam sheet is laid between the bottom surface of the floor and the flooring material, and the floor board is installed on it. It does not use the adhesive, but only the adhesive on the groove and tongue on the side of the floor connecting the floor to the floor to prevent the floor from being separated from each other. It is easy to construct and easy to dismantle, so it is about 10% in Korea and about 60% in Europe is very popular.

The open cell type polyethylene foam sheet (OPEN CELL TYPE XL PE FOAM LAYER) is mainly used for economic reasons between the floor and the floor, but the open cell type crosslinked polyethylene foam sheet (OPEN CELL TYPE XL PE FOAM LAYER) has a sound absorption effect. Because of its excellent resilience (elasticity), almost all use closed cell type cross-linked polyethylene foam sheets (CLOSED CELL TYPE NON-XL PE FOAM LAYER).

However, if it is used for a long time or continuously pressed by heavy objects, the closed cell type non-crosslinked polyethylene foam sheet (CLOSED CELL TYPE NON-XL PE FOAM LAYER) is pressed by the weight of the upper part and loses its elastic function. have.

Thirdly, it is a structure that uses a nail or staple as a means of forming the lower frame structure of the wood material between the floor and the lower base surface and binding the frame and the floor board. Space is needed because the timber frame is necessary under the floor, and most of Europe is currently in need due to hygiene problems of empty space, floor collapse and squeaking due to corrosion of the lower frame and nails over long periods of use, and excessive installation cost. These structures are only used in very few parts of the country, and in our country they are used only in limited places such as special-purpose gymnasiums or school classrooms.

As to solve the above problems, a plurality of insertion holes and adhesive holes are formed, the elastic sound absorbing material constructed on the floor concrete; Anti-vibration rubber inserted into the insertion hole; An elastic reinforcing adhesive filled and cured in the adhesive hole; A wood panel constructed on the elastic sound absorbing material; And wood flooring is constructed on the wood panel; A technology comprising a is disclosed in Patent Registration No. 863295.

However, the elastic wood floor structure disclosed in Patent Registration No. 863295 has the following problems.

First, the wood panel is constructed between the wood maroon and the elastic sound absorbing material is constructed

There is a problem that the construction cost increases because it must be manufactured to correspond to the size of the wooden flooring.

Second, since the wood panels are in contact with each other in a state corresponding to the size of the wood flooring, the elastic sound absorbing material constructed in the lower part functions as the vibration, shock, and noise applied to the wood panels are primarily transmitted. There is a problem that does not work.

Third, there is a problem that the dust-proof rubber must be installed in the lower part of the wooden panel in order to absorb the impact of the wooden flooring.

The present invention has been made to solve the problems and technical bias as described above, an object of the present invention is to provide a wood floor structure using an elastic sound absorbing material to improve the elasticity, sound absorption and shock absorption of the wood flooring.

In order to achieve the above object, the present invention is a concrete floor; An elastic sound absorbing material which is installed on the concrete floor in a state having a predetermined thickness, and has a plurality of accommodating grooves having an uneven shape on the upper surface thereof and a plurality of adhesive holes filled with elastic reinforcing adhesives on the surface of the accommodating grooves; A wood panel constructed in each of the receiving grooves in a state in which an elastic reinforcing adhesive is filled in the adhesive hole of the receiving groove; And a wooden floor board which is constructed on top of the wooden panel so as to intersect with the wooden panel to form a wooden floor. It provides a wooden floor structure using an elastic sound absorbing material comprising a.

In this case, it is preferable that the adhesive holes formed in the elastic sound absorbing material are formed at predetermined intervals.

In addition, the adhesive hole formed in the elastic sound absorbing material is preferably formed in the longitudinal direction along the length of the receiving groove.

On the other hand, the elastic sound absorbing material is preferably made of an open cell cross-linked polyethylene foam sheet (OPEN CELL TYPE XL PEFOAM LAYER).

Wood floor structure using the elastic sound absorbing material of the present invention having the configuration as described above has the following effects.

First, as the wooden panel is installed in each receiving groove formed in the elastic sound absorbing material, the cost of the wooden panel is reduced and the construction cost is reduced, and it is constructed to intersect with the wooden flooring, so that the strength of the wooden panel is maintained as it is. The board is prevented from bending due to shock or vibration.

Second, as the elastic sound absorbing material is level with the upper part of the wood panel, the elastic sound absorbing material is thickly constructed and also keeps contact with the wood flooring, so that various shocks and noises applied to the wood flooring are effectively absorbed. do.

Third, since various shocks and noises are effectively absorbed by the elastic sound absorbing material, there is no need for dustproof rubber as in the prior art, thereby reducing the construction cost.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. The present embodiments and drawings are intended to assist the understanding of the present invention and are not intended to limit the scope of the invention in any way.

1 is an exploded perspective view showing a wooden floor structure using the elastic sound absorbing material according to the present invention, Figure 2 is a combined perspective view showing a combined state of FIG. 3 is a cross-sectional view taken along line II of FIG. 2.

As shown in Figure 1 and 2, the wood floor structure using the elastic sound absorbing material 10 of the present invention is a concrete floor (1), elastic sound absorbing material (10), wood panel 20, wooden flooring ( 30).

The building is provided with a concrete floor 1 on which concrete is poured to form the basis of the building. The concrete floor (1) is a wooden floor is constructed. The present invention provides a structure in which the wood floor to be constructed on the concrete floor (1) to improve durability, maintenance, elasticity and shock absorption.

The present invention It is installed in classrooms, corridors, indoor gymnasiums, and floors of apartment buildings, where shocks and noises must be suppressed.

On the concrete floor 1, an elastic sound absorbing material 10 is disposed. The elastic sound absorbing material 10 is constructed between the surface of the concrete floor 1 and the wood flooring 30 to effectively absorb the noise with mitigation of the shock transmitted to the wood flooring 30 above.

At this time, the concrete floor 1 on which the elastic sound absorbing material 10 is constructed does not necessarily have to be flat. This is because the upper elastic sound absorbing material 10 itself accommodates the upper side of the non-flattened concrete floor 1 as it maintains elasticity. In addition, even if the floor is formed of other materials (plywood surface, tile surface, metal surface, etc.) can be constructed.

At this time, the material of the elastic sound absorbing material 10 is preferably made of an open cell cross-linked polyethylene foam sheet (OPEN CELL TYPE XL PEFOAM LAYER).

The elastic sound absorbing material 10 is formed to have a predetermined thickness and is constructed on the upper concrete floor 1. At this time, the elastic sound absorbing material 10 is formed to have a predetermined thickness to increase its own elasticity and to improve the absorption of shock and noise.

The upper surface of the elastic sound absorbing material 10 is formed with a plurality of receiving grooves 13 to maintain the concave-convex shape. The receiving groove 13 is a place where the wooden panel 20 to be described later is accommodated, in which the depth of the receiving groove 13 is preferably formed to a height corresponding to the height of the wooden panel 20.

To be precise, the upper surface of the elastic sound absorbing material 10 and the upper surface of the wood panel 20 to form the same horizontal plane. Therefore, the stable construction of the wooden maroon 30 to be described later is made.

An adhesive hole 15 is formed on the surface of each receiving groove 13.

The adhesive hole 15 is formed in plural on the surface of the receiving groove 13, the adhesive hole 15 is filled with an elastic reinforcing adhesive 40. At this time, the adhesive hole 15 is preferably formed so as to pass through the elastic sound absorbing material (10).

At this time, the adhesive hole 15 formed in the upper receiving groove 13 is preferably formed at a predetermined interval.

In addition, the adhesive hole 15 formed in the elastic sound absorbing material 10 may be formed in a long hole type along the length of the upper receiving groove 13.

And, the elastic sound absorbing material 10 may be constructed on the concrete floor 1 according to the length of the wooden maroon 30 is constructed, wherein each elastic sound absorbing material 10 is a tape or elastic reinforcing adhesive ( It is preferred to be used in connection with 40).

This is to prevent the moisture generated from the concrete floor 1 from moving to the upper portion of the elastic sound absorbing material 10 through the gap by sealing the gap between each of the elastic sound absorbing material 10.

Next, the wooden panel 20 is accommodated in the receiving groove 13 of the elastic sound absorbing material (10).

As shown in FIG. 3, the wood panel 20 is constructed in each receiving groove 13 in a state in which the elastic reinforcing adhesive 40 is filled in the adhesive hole 15 formed in the receiving groove 13. . Therefore, the wood panel 20 is bound to the elastic reinforcing adhesive 40 filled in each adhesive hole 15 is in a state accommodated in the receiving groove (13).

On the other hand, the elastic reinforcing adhesive 40 is in contact with the upper side of the concrete floor 1 while being filled through the adhesive hole 15 as the adhesive hole 15 penetrates the elastic sound absorbing material 10. As it hardens, it binds to the concrete floor (1).

As a result, while the wood panel 20 is directly bonded to the concrete floor (1) through the elastic reinforcing adhesive (40) while ensuring the firmness of construction, and also the flow or movement of the elastic sound absorbing material (10) Will be prevented.

Next, the wood flooring 30 is constructed on the top of the wood panel 20 to intersect with the wood panel 20 to form a wood floor. At this time, the wood flooring 30 is made to bond with the wood panel 20 using the elastic reinforcing adhesive 40.

In this case, the wood flooring 30 is prevented from being bent by the pressure exerted on the wood flooring 30 as the wood flooring 30 is in contact with the wood flooring in the intersected state. As the upper surfaces between the receiving grooves 13 of the sound absorbing material 10 are in contact with each other, the absorption and vibration of the vibration applied to the wood flooring 30 are absorbed.

On the other hand, the elastic sound absorbing material 10 used in the present invention is specifically a foam having an open cell structure (Open cell type), the connection of the foam cell is manufactured by a cross-linked (Cross linked = XL) method in consideration of durability. . The elastic sound absorbing material 10 processed with such an open cell type crosslinked polyethylene foam sheet (OPEN CELL TYPE XL PE FOAM LAYER) has excellent sound absorption effect, high flame retardancy, excellent heat insulation, and is not harmful to the human body but also has durability. It is long and has excellent oil and chemical resistance.

In addition, since the elastic sound absorbing material 10 is always in contact with the wood flooring 30 while receiving the wood panel 20, the waveform vibration energy of sound waves due to impact or walking on the wood flooring 30 is generated. In this case, it absorbs it well and converts it into thermal energy, thereby effectively absorbing noise.

In addition, in the manufacture of the elastic sound absorbing material 10, the raw material is first foamed by a constant magnification, and it is cut into a suitable thickness and width using a heating wire. Then, using a perforation machine having a predetermined diameter and used after punching the adhesive hole 15 continuously formed in a staggered arrangement of a predetermined interval.

On the other hand, the elastic reinforcing adhesive 40 should have excellent adhesive performance, and when cured, it must satisfy the property of having a permanent property such as rubber. In addition, it should have a liquid form at the beginning for constructability, but even if the liquid has a certain viscosity inherent to flow down itself or it should not be deformed soon after injection.

In the present invention, the elastic reinforcing adhesive 40, which plays various roles such as an adhesive effect, an anti-vibration rubber effect, and a protective effect of the elastic sound absorbing material 10, is a remarkable development of petrochemicals. As it is developed, it is easy to purchase.

For example, when polyurethane is used, the shock absorption rate and adhesion are excellent, and the restoring force (elasticity) is also excellent. In addition, at the time of storage, it is preserve | saved in the liquid state which has a constant viscosity in an airtight pack. Upon filling, it starts to harden and has elastic properties. Polyurethane having such properties is excellent in the restoring force (elasticity) that can support or tolerate the load of the upper part, inhibits bacterial growth at the construction site and has no corrosion effect, so excellent adhesive strength of the elastic reinforcing adhesive of the present invention ( 40) is suitable.

On the other hand, the elastic sound absorbing material 10 used in the present invention has a good sound absorption effect, due to the nature of the open cell structure there is a lack of elasticity to bear this if there is a constant pressure or load.

Therefore, the elastic reinforcing adhesive 40 used in the present invention is a liquid having a certain viscosity at the time of filling or when a certain time after filling is changed to a physical property such as rubber to have elasticity to bear the load if there is an upper load Or it is desirable to perform the function of minimizing the effect of the load directly on the elastic sound absorbing material 10 by recovering the original shape as soon as the load disappears.

As described above, the wood floor structure using the elastic sound absorbing material 10 of the present invention is constructed so that the wood floor panel 30 and the wood panel 20 cross each other while reducing the amount of the wood panel 20 used. As the sound absorbing material 10 is thickly constructed, noise is effectively absorbed while the durability of the wood floor is enhanced after construction.

As mentioned above, although this invention was demonstrated through the preferable Example, this is an objective to help understanding of this invention, and is not intended to limit the technical scope of this invention to this.

Those skilled in the art will appreciate that various modifications and variations can be made without departing from the spirit of the present invention.

For example, the material of the elastic sound absorbing material 10, the height of the receiving groove 13 and the thickness of the wood panel 20 corresponding thereto, the spacing and shape of the adhesive hole 15, etc. are the criteria for determining the technical scope of the present invention. Needless to say, it cannot be, and is determined only by the claims.
