Description

Impact sound reduction floor plate reinforcement structure system and its reinforcement method {Reinforced Floating Floor System to Reduce Heavy Impact Noise and Force}

The present invention relates to a floor plate reinforcement structure system for reducing impact sound and a method for reinforcing the same, and more particularly, a foamed concrete layer is formed on top of a floor slab to reinforce the slab, and an anti-vibration rubber block is used to form a buffer space on top of the foamed concrete layer. The present invention relates to an impact sound reducing floor plate reinforcement structure system in which the upper structure of a buffer space is lightweight by sequentially forming only an insulation board layer, a cold and hot water pipe, and a mortar layer on the top in a state in which the part is provided, and a reinforcement method thereof.

Interfloor noise generated in apartment houses is transmitted in the form of solid propagation sound by shock and vibration caused by walking, moving objects, shaking, and falling, vibrating structures such as slabs and walls, and these solid propagating sounds are transmitted in the space below. It changes to air propagation sound, causing inter-floor noise.

The sound of children running, the movement of furniture such as chairs and tables, the impact of walking, the vibration of washing machines or vacuum cleaners, the vibration of mechanical equipment such as elevators, and the vibration of running water in water supply and drainage pipes are typical causes of noise between floors. It is classified as a heavy impact sound that causes discomfort.

Various proposals are being made to solve inter-floor noise, and representative methods include the floating floor method, the heavy/high rigidity floor method, the surface buffer method, and the sound insulation double ceiling method.

The floating floor method minimizes the impact energy transmitted to the slab by using a buffer material as shown in FIG. There was a limit that was not effective in reducing the impact sound.

In order to solve this problem, Korean Patent Publication No. 10-2004-0067761 "Method and device for preventing noise in multi-unit dwellings such as apartments" (published on July 30, 2004, hereinafter referred to as 'Prior Art Document 1') is proposed. has been As shown in FIG. 1B, the prior art document 1 is provided with a small spacer 6 on the top of the floor slab so that the air layer 1 is formed, and the foamed concrete 2 is poured through the formwork 5 After that, the pipe 7 was provided to pour the finishing mortar 3, and the finishing material 4 was placed on the top.

However, in the prior art document 1, the layer of foamed concrete (2) and the finishing mortar (3) are disposed on the top of the spacer (6) to form a thickness of about 100 to 110 mm, causing sagging as an excessive upper load is applied Thus, there was a limit in that the air layer 1 could not be substantially formed.

In addition, the weight and high-stiffness floor method is to prepare for weight impact sound by relatively increasing the thickness or density of the floor slab and weighting it, but there is a limit applicable only to a stretch structure, and the overall self-weight of the structure is increased, There was a limit to inefficiency due to poor space utilization.

In this regard, Korean Patent Publication No. 10-2006-0067325 "double slab structure of a building" (published on June 20, 2006, hereinafter referred to as 'Prior Art Document 2') has been proposed. As shown in FIG. 1c, the prior art document 2 is intended to reduce the natural frequency by providing an anti-vibration member (6a) and a composite layer plate member (6b) between the double slab layers.

However, in the prior art document 2, the process is cumbersome as the anti-vibration member 6a and the composite layer plate member 6b must be provided in the construction process of the slab, and there is a limit applicable only to new structures.

On the other hand, recently, Korean Patent Publication No. 10-2021-0157063 "Floor Impact Sound Reduction Structure Using Buffer Material with Sound Insulation Space and Construction Method" (published on December 28, 2021, hereinafter referred to as 'Prior Art Document 3') this has been proposed. As shown in FIG. 2, the prior art document 2 forms the air layer 1 using a ready-made buffer block 8 so that the air layer 1 is formed on the top of the slab, and the insulation material 9 and The pipes (7) were sequentially provided and the finishing mortar (3) was poured.

The buffer block 8 is formed to have an arcuate structure at the bottom and can sufficiently resist the vertical load of the upper structure.

According to the impact sound reducing floor plate reinforcement structure system and reinforcement method of the present invention, a foamed concrete layer is formed on the top of the floor slab to reinforce the slab, thereby increasing the rigidity of the slab and minimizing the resonance phenomenon in the low frequency sound range.

In addition, since the upper structure of the buffer space can be lightened in weight by sequentially forming only the insulation board layer, the cold and hot water pipe, and the mortar layer at the top in the state in which the buffer space is prepared with anti-vibration rubber blocks on the top of the foamed concrete layer, the buffer space is stable. formation is possible

Furthermore, it is possible to stably distribute the upper load transmitted to the anti-vibration rubber block through the wire mesh.

In particular, since the foamed concrete layer is formed directly above the slab to reinforce the slab, it is easy to apply to new structures as well as remodeling structures.

In addition, material separation and cracking between the slab and the foamed concrete layer can be prevented by disposing reinforcing beams on top of the slabs and pouring foamed concrete between the reinforcing beams.

In addition, there is an advantage in that the strength of the slab is improved through the synthesis effect of the reinforcing steel and the foamed concrete.

In addition, since the height of the foamed concrete layer can be minimized by the reinforcing beams, the overall thickness of the floor plate can be formed thin, so space utilization is improved, and there are further advantages in a remodeling structure with a low floor height.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the following examples. This embodiment is provided to more completely explain the present invention to those skilled in the art.

3A to 3C are cross-sectional views showing an impact sound reducing floor plate reinforcing structure system according to an embodiment of the present invention, the foamed concrete layer 10 so as to come into contact with the wall W on the upper part of the floor slab Sb, and anti-vibration A buffer space portion (S) provided between the rubber block 20 and the anti-vibration rubber block 20, the wire mesh 30, the insulation board layer 40, the cold and hot water pipe 50 and the finishing mortar layer 60 are are formed sequentially.

The foamed concrete layer 10 is formed by pouring and curing foamed concrete on the upper part so as to come into contact with the floor slab Sb. The foamed concrete layer 10 forms an air layer by mixing a foaming agent with lightweight concrete, or , It can be constructed by mixing Styrofoam particles (poles) in place of the foaming agent.

The foamed concrete layer 10 adjusts the floor level of the slab (Sb) and at the same time increases the overall stiffness of the floor plate based on the increase in the thickness of the slab (Sb) can be expected. The foamed concrete layer 10 may be constructed with a thickness of 40 to 70mm, preferably 40mm, and when the stiffness of the slab (Sb) is increased by the foamed concrete layer 10, the frequency of the entire floor plate increases, resulting in a low frequency sound range. resonance can be reduced.

The anti-vibration rubber block 20 performs a function of absorbing impact energy while accommodating a vertical load caused by an upper structure. To this end, the anti-vibration rubber block 20 is preferably made of anti-vibration rubber having dynamic stiffness capable of supporting up to 3.2 kgf of vertical load applied from the top per unit block, and a plurality of anti-vibration rubber blocks 20 are arranged In doing so, it is preferable to arrange the vertical load of the upper structure to be distributed and to act less than 3.2kgf per unit block.

In addition, since the plurality of anti-vibration rubber blocks 20 are provided at regular intervals, a buffer space portion S is provided between the anti-vibration rubber blocks 20 on the upper part of the foamed concrete layer 10 . The buffer space portion (S) minimizes the impact energy transmitted to the slab by forming an air layer on the bottom plate capable of blocking the transmission of solid propagation sound.

At this time, the anti-vibration rubber block 20 may be manufactured to have a height of about 10 mm, and as an upper structure of the anti-vibration rubber block 20 to be described later, the insulation board layer 40, the cold and hot water pipe 50, and the finishing mortar layer Since all (60) can be constructed with a thickness of 60 mm or less even when combined, the amount of deflection can be minimized by reducing the weight of the upper structure, so that the buffer space portion (S) can be formed stably enough even for the anti-vibration rubber block 20 of around 10 mm. can

등 다양한 형상으로 제작될 수 있으며, 재질은 네오플랜계 합성고무, 실리콘계 방진고무, 클로로플렌계 방진고무 등이 사용될 수 있다.The anti-vibration rubber block 20 has a top-down, left-right symmetrical planar shape.

It can be manufactured in various shapes, such as neoprene-based synthetic rubber, silicon-based anti-vibration rubber, chloroprene-based anti-vibration rubber, etc.

On the other hand, an insulating board layer 40 is provided on the top of the anti-vibration rubber block 20, and the vertical load and impact load of the upper structure are distributed through the insulating board layer 40 through the anti-vibration rubber block 20. can be conveyed The insulation board layer 40 may be made of EPS panel (expanded polystyrene), XPS panel (extrusion insulation board), soft and hard urethane board, PF board, glass wool, mineral wool, etc., and has a thickness of 20 to 40 mm It can be formed to have.

However, as shown in FIG. 4 , a wire mesh 30 may be provided on top of the anti-vibration rubber block 20 . The wire mesh 30, as an upper structure, more effectively distributes the vertical load and the impact load of the insulation board layer 40, the cold and hot water pipe 50, and the finishing mortar layer 60 to provide a buffer space at the bottom of the wire mesh 30. It functions so that the unit (S) can be stably provided.

Preferably, the anti-vibration rubber block 20 may be arranged to support the intersection 31 of the wire mesh 30, which is a node where the vertical load of the upper structure is concentrated. To this end, a seating groove 21 may be formed on the upper surface of the anti-vibration rubber block 20 so that the intersection portion 31 of the wire mesh 30 is seated.

Typically, since the wire constituting the wire mesh 30 has a diameter of 3 to 5 mm, it may be formed in a straight line in which the wire can be seated, but the intersection 31 of the wire mesh 30 It is preferable to form a cross-shaped structure so that individual wires to be formed do not protrude upward. At this time, the individual wire may be made of a stainless steel wire or a galvanized steel wire, and may be replaced with an integrated expanded metal.

According to one embodiment, the wires of the wire mesh 30 have a diameter of 4 mm, and the intersections 31 are formed at intervals of 50 to 200 mm up and down, left and right, and 50 to 50 up and down, left and right so as to correspond to the intersection 31. Anti-vibration rubber blocks 20 may be disposed at intervals of 200 mm.

On the other hand, the hot and cold water pipe 50 is provided on the top of the insulation board layer 40, and the finishing mortar layer 60 is poured on top of the insulation board layer 40 so that the cold and hot water pipe 50 is buried. The impact sound reducing floor plate reinforcement structure system of the invention is formed. At this time, it is preferable that the finishing mortar layer 60 is formed to be 40 mm or less to ensure space utilization.

According to the impact sound reducing floor plate reinforcement structure system according to a preferred embodiment of the present invention, the vertical load and impact load of the upper structure are transferred from the finishing mortar layer 60 to the wire mesh 30, and the transmitted vertical load and impact load Part of the noise is dissipated by the anti-vibration rubber block 20, and the rest is transmitted and dissipated as air propagation sound by the buffer space (S). Therefore, only some residual load is transmitted to the slab (Sb) through the aerated concrete layer 10 in a state where many vertical loads and impact loads are dissipated, but the transmitted residual load is also transferred to the slab (Sb) by the aerated concrete layer 10 ( Sb) is implemented to increase the frequency of the bottom plate, thereby minimizing the resonance phenomenon in the low-frequency sound range that forms the weight impact sound.

On the other hand, depending on the embodiment, a reinforcing steel 70 may be additionally provided above the floor slab Sb as shown in FIG. 6 in order to reduce a resonance phenomenon based on an increase in frequency. The reinforcing steel 70 is preferably made of stainless steel or galvanized steel. As described above, most of the inter-floor noise is weight impact noise, which is generated in the low-frequency sound range, so that the frequency of the slab (Sb) can be further increased by reinforcing the stiffness by additionally providing a reinforcing steel 70 on the upper part of the floor slab (Sb). And, based on the increased frequency, the resonance phenomenon in the low-frequency sound range can be remarkably reduced.

At this time, the foamed concrete layer 10 is poured at the same height so as to come into contact with the slabs Sb between the reinforcing steels 70, and the anti-vibration rubber block 20 can be placed on top of the foamed concrete layer 10. there is. The reinforcing steel 70 is a lightweight steel with a thickness of about 1 mm and can be manufactured in various shapes, but C-shaped steel (channel member), L-shaped steel ( Angle members), H-beams, I-beams, etc., are preferably flanged sections formed vertically.

More specifically, as shown in FIG. 7, in the reinforcement section 70, a rim member 71 is disposed at a portion where the floor slab Sb and the wall W meet, and between the rim members 71 A reinforcing member 72 may be disposed.

The rim member 71 is preferably a C-beam or L-beam with a web formed on one side so as to come into contact with the wall (W), and the anchor bolt 73 fixed to the wall (W) is the web of the rim member 71 It can be fastened so as to pass through the through hole formed in. In addition, the reinforcing members 72 are spaced apart from each other at regular intervals between a pair of opposing rim members 71, and the anchor bolts 73 fixed to the slab Sb are attached to the lower portion of the reinforcing member 72. It may be fastened to pass through a through hole formed in the flange. At this time, as shown in FIG. 7, the reinforcing member 72 may be C-beam, H-beam, I-beam, or the like.

Both ends of the reinforcing member 72 are preferably provided so as to come into contact with the web of the frame member 71, and may be welded in advance. In addition, depending on the embodiment, it is also possible to form one reinforcing member 72 by coupling the webs of the C-beams so as to contact each other. As a result, ready-made lightweight steel can be used, and the foamed concrete layer 10 can be inserted into the pair of flanges of the reinforcing member 72 to induce a rigidity effect, thereby preventing separation of materials and increasing rigidity. can be expected

Preferably, the reinforcing beams 70 are formed to have a height of 40 mm to 70 mm, and the reinforcing members 72 may be spaced apart at intervals of 1 m. Since the foamed concrete layer 10 is poured in a partitioned state by the reinforcing member 72, it is possible to achieve sufficient rigidity increase even if the height of the foamed concrete layer 10 is not formed relatively high, and the slab (Sb) and foam It functions so that material separation does not occur between the concrete layers 10.

Furthermore, even if some material is separated between the slab (Sb) and the foamed concrete layer 10, it is possible to prevent cracks from occurring in the foamed concrete layer 10 because it is partitioned by the reinforcing member 72. As a result, the impact sound reduction floor plate reinforcement structure system of the present invention uses the existing slab (Sb) as it is in the case of a remodeling structure, and since the effect of reducing weight impact sound through the increase in the rigidity of the slab (Sb) can be expected, its utilization is high. expected to be very high.

Hereinafter, the impact sound reducing bottom plate reinforcement method of the present invention will be described in detail. As shown in FIG. 8, the impact sound reducing floor plate reinforcement method of the present invention includes a foamed concrete layer forming step (S10), an anti-vibration rubber block providing step (S20), a wire mesh providing step (S30), and an insulation board layer forming step (S40). ), cold and hot water pipe providing step (S50) and finishing mortar layer forming step (S60).

First, the foamed concrete layer forming step (S10) is a step of forming the foamed concrete layer 10 by pouring and curing the foamed concrete on the top of the floor slab (Sb). The foamed concrete layer 10 is formed by pouring and curing foamed concrete on the upper part so as to come into contact with the floor slab (Sb), and the foamed concrete layer 10 is formed by mixing a foaming agent with lightweight concrete to form an air layer. desirable.

The foamed concrete layer 10 adjusts the floor level of the slab (Sb) and at the same time increases the overall stiffness of the floor plate based on the increase in the thickness of the slab (Sb). phenomenon can be reduced.

The anti-vibration rubber block providing step (S20), which proceeds thereafter, is a step of providing the anti-vibration rubber block 20 at regular intervals so that a buffer space portion S is provided on the top of the cured foamed concrete layer 10. The anti-vibration rubber block 20 performs a function of absorbing impact energy while accommodating a vertical load caused by an upper structure.

In particular, as shown in (a) of FIG. 5, valleys 22 are repeatedly formed in one direction on the bottom surface of the anti-vibration rubber block 20 to prevent pushing by a load, and the foamed concrete layer 10 By minimizing the contact area with the solid-state propagation sound can be reduced. In another embodiment, as shown in (b), a plurality of concave grooves 23 or protrusions (not shown) may be formed on the bottom surface of the anti-vibration rubber block 20 to minimize the contact area.

In addition, a buffer space (S) is provided between the anti-vibration rubber blocks (20) on top of the foamed concrete layer (10). The buffer space portion (S) minimizes the impact energy transmitted to the slab by forming an air layer on the bottom plate capable of blocking the transmission of solid propagation sound.

Next, the wire mesh providing step (S30) is a step of providing the wire mesh 30 on top of the anti-vibration rubber block 20. Preferably, the anti-vibration rubber block 20 is preferably arranged to support the intersection 31 of the wire mesh 30, which is a node where the vertical load of the upper structure is concentrated.

To this end, a cross-shaped seating groove 21 may be formed on the top of the anti-vibration rubber block 20 so that the intersection 31 of the wire mesh 30 is inserted, and it is manufactured so that the wire does not protrude upward. Preferably, the depth of the grooves of the one-way wire of the cross-shaped seating groove 21 is relatively deep, and the depth of the grooves of the other orthogonal wires can be formed to be relatively shallow.

Accordingly, since the seating groove 21 of the anti-vibration rubber block 20 may be disposed after being fitted to the intersection 31 of the wire mesh 30, the wire mesh providing step (S30) is substantially equipped with an anti-vibration rubber block. The steps can be done concurrently.

In the subsequent step of forming the insulating board layer (S40), the insulating board layer 40 is formed on the wire mesh 30. The insulation board layer 40 may be made of EPS panel, XPS panel, rigid urethane board, PF board, glass wool, mineral wool, etc., and has a thickness of 20 to 40 mm, preferably 20 mm. can

Next, the cold and hot water pipe providing step (S50) is a step of providing the cold and hot water pipe 50 on the top of the heat insulation board layer 40, and finally, the cold and hot water pipe 50 on the top of the heat insulation board layer 40 The finishing mortar layer forming step (S60) of forming the finishing mortar layer 60 by pouring and curing the mortar to be buried proceeds.

Meanwhile, before the foamed concrete layer forming step (S10), a step (S00) of providing a reinforcing steel 70 on top of the floor slab (Sb) may be additionally performed. The reinforcing steel 70 can reduce the resonance phenomenon based on the increase in the frequency of the upper part of the floor slab (Sb).

As shown in FIG. 6, the reinforcing steel 70 may be manufactured by integrally combining the frame member 71 and the reinforcing member 72 according to a pre-designed shape, but the slab Sb is separated from each other. Alternatively, it may be fixed to the wall (W).

In one embodiment, the step of providing reinforcing beams (S00) may include a step of arranging a frame member (S01) and a step of arranging a reinforcing member (S02). The rim member arrangement step (S01) is a step of arranging the rim member 71 at the portion where the floor slab (Sb) and the wall (W) meet. Preferably, the anchor bolts 73 fixed to the wall (W) can be fastened so as to pass through through-holes formed in the web of the frame member 71.

The reinforcing member arrangement step (S02), which proceeds thereafter, is a step of arranging reinforcing members 72 at regular intervals between the frame members 71, and the anchor bolts 73 fixed to the slab (Sb) are reinforcing members ( 72) may be fastened to pass through a through hole formed in the lower flange, and the reinforcing member 72 may be C-beam, H-beam, I-beam, or the like.

Thus, by disposing the reinforcing steel 70 on the upper part of the floor slab (Sb) and pouring the foamed concrete between the reinforcing steels 70, material separation and cracking of the slab (Sb) and the foamed concrete layer 10 are prevented. Since it can be prevented, there is a more advantageous advantage in the remodeling structure using the existing slab (Sb) as it is. In addition, there is an advantage in that the strength of the slab is improved through the synthesis effect of the reinforcing steel and the foamed concrete.

In addition, since the height of the foamed concrete layer 10 can be minimized by the reinforcing steel 70, the overall thickness of the floor plate can be formed thin, so space utilization is improved and utilization is high in a remodeling structure with a low floor height.
