The present invention relates to a floor noise reduction material of a building, and more particularly, it is constructed between floors of a building to completely block noise generated between floors, thereby improving customer satisfaction, as well as providing an excel pipe for heating. The present invention relates to a floor noise reduction material of a building to facilitate construction.

In general, the impact sound that is applied to the building structure of apartment houses such as apartments and villas is transmitted to all directions of solid sound generated by people walking, opening and closing of doors, moving objects, starting or stopping equipment, etc. This causes the surface of the building structure to vibrate, as well as being switched to airborne sound, which is perceived as noise when it is heard by people around it.

For example, the impact of falling objects on the floor or the sound of moving chairs generates solid sound, which is transmitted through the floor slab and the walls to other adjacent rooms, especially the floor slab. The propagation through the floor below is called interlayer noise.

Nowadays, as these inter-floor noise problems are seriously raised in multi-unit houses, regulations on house construction standards have been strengthened and revised.

The regulations stipulate that the floor impact sound between floors should be 58 decibels (db) or less, and the heavy impact sounds should be 50 decibels (db) or less or have a standard floor structure as determined and announced by the Minister of Construction and Transportation.

As such, conventional interlayer floor structures for reducing and minimizing severely raised interlayer noise have been proposed. Such conventional interlayer floor structures are based on the concrete slab 1, as shown in FIG. Lightweight foam concrete layer (2) is formed on the upper part, and an excel pipe (3) for heating and a mortar layer (4) for finishing are formed thereon, and a floor decorative layer (monorium, solid wood, tile, etc.) is formed thereon ( 5) consists of.

In the interlayer floor structure of the above structure, the lightweight foam concrete layer 2 formed on the concrete slab 1 is responsible for attenuating the impact sound or noise, but the effect is insignificant.

For this reason, in order to more effectively block noise and impact, a construction method for forming an interlayer shock-absorbing material between the concrete slab and lightweight foamed concrete is disclosed.

The conventional interlayer shock sound absorbing material 10 is provided as various structures, and typically has hard styrofoam materials 11 and 12 having a predetermined thickness in the upper and lower portions as shown in FIG. It is provided with a structure in which the intermediate sound insulating material 3 made of polyester material having a large gap is sandwiched in a sandwich form.

However, the above-described conventional interlayer shock sound absorbing material also does not reliably alleviate the impact, thereby failing to completely reduce the interlayer noise of the building.

In addition, as shown in FIG. 1, an excel pipe for heating is installed on the interlayer impact sound absorbing material, and mortar is applied and cured, and then a flooring material is installed. In this case, a gap may occur between the shock absorbing material and the mortar. In this case, when the gap is generated, there is a problem in that the function of the cushioning material is deteriorated due to the filling of the gap with moisture.

Therefore, the present invention was devised to solve the above problems, and additionally installs a rubber member having excellent elasticity at regular intervals in the buffer member located at the bottom, thereby reducing the noise between floors of the building more reliably. In addition, by increasing the binding force between the mortar and the cushioning member to which the Excel pipe is applied internally to eliminate the gap between each other, to provide an interlayer noise reduction material of the building to prevent the functional degradation of the buffer member. There is this.

The present invention for achieving the above object is made of foamed polystyrene or expanded polypropylene material, the bottom surface and the buffer member is formed in the insertion hole at regular intervals; A portion of the buffer member is inserted into and fixed, characterized in that it comprises a plurality of rubber members for the buffer function.

In this case, the rubber member, it is preferable to be made of an insertion portion which is part of which is fixed to the insertion hole of the buffer member, and the contact surface portion extending from the insertion portion and protruding from the buffer member by a certain height. .

In addition, the contact surface portion is larger than the insertion portion is formed in a larger diameter so as to surround the surrounding of the buffer member inserted into the support state, but the planar portion of the contact surface portion a plurality of irregularities in the circumferential direction at a predetermined interval It is preferably formed.

In this case, it is preferable that grooves are formed along the circumference at a predetermined depth between the uneven parts, and a plurality of linear exhaust grooves connecting the grooves are formed at regular angle intervals.

On the other hand, after the Excel pipe is seated on the upper surface of the buffer member, it is preferable to apply a mortar so that a part of the mortar is introduced into the insertion hole of the buffer member.

On the other hand, it is preferable that the reinforcing member made of PVC or PE material is interposed between the buffer member and the rubber member.

In addition, a plurality of guide forms having a predetermined height and a predetermined width may be attached to the upper surface of the shock absorbing member at predetermined intervals in order to support and support the Excel pipe.

In this case, the guide form, it is preferable that the guide groove of the insertion shape is formed in the straight direction through which the Excel pipe passes.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a bottom perspective view of the floor noise reduction material of the building according to the present invention, Figure 4 is a cross-sectional view of FIG.

As shown, the floor noise reduction material of the building according to the present invention is made of expanded polystyrene (EPS: Expandable Polystyrene) or expanded polypropylene (EPP) material, the insertion hole 22 in a vertical direction at regular intervals The formed buffer member 20 forms a main body.

In the insertion hole 22 of the shock absorbing member 20, a part of the rubber member 50 that functions as a shock absorbing function is inserted and fixed.

3 and 4, the rubber member 50 is made in a circular shape, the insertion portion 50-1 is a part of the insertion hole 22 of the buffer member 20 is fixed to the insertion hole (22) And, it is formed of the contact surface portion 50-2 extending from the insertion portion 50-1 and protruding from the buffer member 20 by a predetermined height.

In this case, the close contact surface portion 50-2 is formed to have a larger diameter than the insertion portion 50-1, and thus the close contact portion 50-2 is in close contact with a state surrounding the buffer member 20 in which the insert portion 50-1 is inserted. Let's go.

On the other hand, the concave-convex portion 52 is formed in the circumferential direction at regular intervals on the planar portion of the contact surface portion 50-2.

Therefore, when an impact is applied by the cylindrical grooves 54 formed between the uneven parts 52, the buffering effect is increased.

In this case, it is preferable to form the exhaust groove 56 to cross the uneven parts 52 of the contact surface part 50-2 over about four directions.

That is, when an impact is applied to the interlayer noise reduction material of the building including the rubber member 50, the impact is applied to the contact surface part 50-2 of the rubber member 50, thereby compressing the uneven parts 52. In this case, air existing in the grooves 54 formed between the uneven parts 52 may be compressed to reduce the buffering effect, so that pressure is applied to the uneven parts 52 to prevent this. In the case of being compressed and compressed, the air present in the groove 54 is allowed to escape to the outside through the exhaust groove 56, thereby making it possible to have a more certain shock absorbing effect.

As described above, in a state in which a part of the inserting portion 50-1 of the rubber member 50 is inserted into and fixed to the insertion hole 22 of the shock absorbing member 20, it is seated on the bottom slab, and then excels thereon. When the pipe 30 is settled and then the mortar 40 is applied and cured, a part of the mortar is cured in a state of entering the insertion hole 22 of the buffer member 20, thereby increasing the binding force and forming a gap therebetween. This will not happen.

That is, hardening is performed in a state where a part of the mortar 40 flows into the insertion hole 22 of the shock absorbing member 20, so that the shock absorbing member 20 grips a part of the mortar 40. Bonding power is increased.

In the state where the interlayer noise reduction material of the building having the structure described above is installed, when the interlayer noise is generated by the impact, the shock absorbing member 20 simultaneously absorbs the shock and simultaneously absorbs the shock absorbing member 20. The rubber member 50 installed at a predetermined interval in the) absorbs the impact again, and thus the noise between the layers is more completely blocked.

In this case, as described above, the contact surface portion 50-2 in close contact with the upper surface of the concrete slab in the rubber member 50 is easily crushed by a plurality of irregularities 52 formed in a circumferential shape at a predetermined interval and impact. Of course, the air present in the grooves 54 formed between the uneven parts 52 is discharged to the outside through the exhaust grooves 56, thereby absorbing the shock more reliably.

 On the other hand, Figure 5 is a cross-sectional view showing the configuration of the floor noise reduction material of the building according to another embodiment of the present invention, as shown, the reinforcing member having a predetermined thickness between the buffer member 20 and the rubber member ( 60) may be further laminated.

In this case, the reinforcing member 60 is made of a PVC or PE material, but part of the reinforcing member 22 into the insertion hole 22 of the cushioning member 20, so that the rubber member 50 is a buffer member In the state inserted into the insertion hole 22 of the 40 can be prevented from being easily separated.

That is, since the separation is not easily performed by the frictional force between the reinforcing member 60 and the rubber member 50, the structural binding force can be further strengthened.

On the other hand, Figures 6 and 7 according to another embodiment of the present invention, it can be attached to the guide foam 70 of a certain height and a predetermined width at a predetermined interval on the upper surface of the buffer member 20.

The guide form 70, which is attached in a predetermined arrangement, can be formed of the same material or PVC material as the buffer member 20, the guide groove 72 in a straight direction through which the Excel pipe 30 passes. It is preferable to set it as the structure in which) is formed.

The guide groove 72, the installation direction of the Excel pipe 30 may be in the longitudinal or transverse direction, it is preferable to be formed to cross in the cross (+) shape.

Accordingly, a plurality of guide foams 70 are attached to the upper surface of the shock absorbing member 20, and mortar is applied while the Excel pipe 30 is seated along the guide grooves 72 of the guide foam 70. When cured, the mortar is in a state of holding the guide form 70 of the buffer member 20, so that the binding force is increased so that a gap does not occur between the mortars.

For reference, in FIG. 6 illustrating the present embodiment, a guide form 70 is formed in the state in which the buffer member 20 and the rubber member 50 are in direct contact with each other. After the reinforcing member 60 is interposed between the member 20 and the rubber member 50, the guide foam 70 is attached to the upper surface of the shock absorbing member 20, and then the guide of the guide foam 70. The Excel pipe 30 may be seated in the groove 72 and then mortar may be applied.

As described above, according to the floor noise reduction material of the building according to the present invention, the rubber for absorbing the shock to the bottom of the buffer member as well as blocking the floor noise in the shock absorbing member excellent in shock absorption function. Since the member is installed, there is a very useful effect that almost completely blocks the noise between the floors to satisfy customer satisfaction.

In addition, the buffer member is provided with insertion grooves at predetermined intervals, and since there is no gap due to excellent binding force between the mortar applied later and the buffer member, moisture does not occur and the buffer member functions as a function. There is also an effect that can prevent problems such as loss of.

In addition, the guide foam is formed on the upper surface of the buffer member is formed with a guide groove for seating and supporting the Excel pipe, it is excellent in the binding force between the mortar and the buffer member to be applied later, bar is not generated, moisture, etc. There is also an effect that the problems such as loss of the buffer member does not occur more prevented.
