Description

Floor impact sound cut-off construction of a build}

The present invention relates to a floor impact sound blocking structure, and more particularly, to a floor impact sound blocking structure of a building that is constructed on each floor concrete slab to block noise between buildings such as a multi-family house.

In general, apartments or multi-family apartments share the walls and floors with neighboring houses, so light impact sounds such as sound falling from the walls and floors of neighboring households or sounds accompanied by moving furniture can be used. When running, there is a problem that the noise and weight impact sound generated during the impending walk of the adult when the object falls to the concrete slab lower layer caused a serious noise pollution.

In order to solve the problem of inter-layer noise, a method of reducing the impact sound by making the slab difficult to vibrate due to the impact on the floor or lowering the amplitude of the floor vibration due to the impact by increasing the slab mass is generally used. Was adopted. However, the slab thickness affects the structure itself or the cost of construction, and the government agency restricts the minimum standard floor structure according to the structural type. Therefore, there is a limit in decreasing the impact sound by increasing the slab mass.

Accordingly, the wet bottom method of reducing the impact sound by inserting the buffer layer has been widely adopted. This is based on the principle that the impact energy is not directly transmitted to the structure or is absorbed in the transfer process, and is a heat-insulating buffer material (pad type by waste tire crushed rubber chip, synthetic rubber foam + polymer, polyethylene) on the slab bottom plate. It is a method using foamed concrete mortar as a filling layer for acoustically disconnecting the structure with polymer foam material (E-Glass Fiber, etc.).

In the wet floor method, a thermal insulation buffer is installed to block interlayer noise while securing insulation on the floor of the slab, and a filling layer is formed by pouring foam concrete on top of the insulation buffer, and a floor plastering layer is used as a heating piping and finishing mortar. It is a method of forming. However, such a wet floor method does not completely remove the noise between floors, and has a disadvantage in that the air is long and the workability is poor because the wet construction must be performed several times.

Korean Patent Laid-Open Publication No. 2004-67761 discloses a floating floor method in which an ondol structure including bubble concrete is separated from a concrete slab by using an air tube by installing a plurality of spacers. In addition, Korean Patent Publication No. 2005-102826 discloses another floating floor method in which an air layer is formed by using a support member between two parallel plates of the heat insulating buffer layer in forming a heat insulating buffer layer on a concrete slab.

However, the conventional floated flooring method has a limitation in handling the impact sound of weight, and the discomfort caused by the swelling or resonance of the underfloor slab is created, thereby reducing the coziness of the inherent ondol structure. It is not easy to maintain the precision of the buffer layer to maintain it, and the long-term fatigue effect of the buffer layer is also severe, and since the process is increased in two or three steps in the construction, it is very disadvantageous in terms of the construction of the on-floor floor and the response due to the density change of the buffer layer. there is a problem.

The problem to be solved by the present invention is to provide a floor shock sound blocking structure of the building that can more effectively cope with the load and impact energy, while preventing heat loss and resonance phenomenon.

Another problem to be solved by the present invention is to implement a bottom impact sound blocking structure that can further shorten the air in implementing the blocking structure as a semi-wet method.

As a means for solving the above problems, the present invention, the support layer 10 is provided on the concrete slab (SL) of the building, the heat reflector 40, the damping member 50 and the upper portion of the support layer 10 and In the bottom impact sound blocking structure in which the finishing mortar layer 60 is sequentially installed, the support layer 10 is provided with a through hole 110 at a predetermined interval, and the elastic support 30 is formed under the through hole 110. The fitting protrusion 314 of the () is supported so that the support layer 10 is supported by the concrete slab SL, and the elastic support 30 provided between the concrete slab SL and the support layer 10. The first space portion (S1) is formed by the, the elastic support 30 is the projection protrusion 314 is formed to project the upper portion of the center portion of the dish-shaped support portion 310, the elastic fitting to the fitting protrusion 314 The washer 340 is fitted, the elastic pad 330 is provided at the lower end of the support 310 The upper portion of the heat reflection member 40 is provided with a band-shaped damping member 50 having a predetermined thickness and width, and the buffer insulation layer 20 is installed on the damping member 50 to provide the heat reflection material ( A second space portion S2 is formed between the buffer insulation layer 40 and the wire mesh 80 between the buffer insulation layer 20 and the finishing mortar layer 60.
A height adjustment screw 320 is provided below the support part 310 of the elastic support 30 to adjust the horizontality of the support layer 10.

According to the floor shock sound blocking structure of the building according to the embodiment of the present invention, two spaces are formed, such as the first space portion by the elastic support and the second space portion by the damping member. Therefore, it is possible to implement the floor shock sound blocking structure that can effectively cope with the load and impact energy to reduce the noise between the floor more efficiently.

In addition, according to the blocking structure according to the present embodiment, by forming a heat reflecting material and a buffer insulating layer having a heat reflection function in the middle, it is possible to more effectively prevent the heat loss conducted and lost through the concrete slab during the heating process energy efficiency It is possible to implement a floor shock sound blocking structure that can be further improved.

Also, in the construction, as in the first floor construction using a buffer insulation layer such as a support layer and styrofoam, the construction is carried out by a semi-wet method in which a finishing mortar layer is formed by pouring ocher mortar or cement mortar on the dry construction after dry construction. As a result, unlike the wet method, which relies solely on conventional mortar casting, the air according to its construction can also be shortened.

1 to 2, the bottom impact sound blocking structure according to the present invention, the support layer 10, the heat reflector 40, the damping member 50, the buffer insulation layer 20, the finishing mortar layer 60 is below Based on the construction constructed to form a layer in order from, the support layer 10 is installed under the elastic support 30, the impact sound blocking structure according to this embodiment is consistent with the concrete slab (SL) that is the construction target surface Spaced apart. The configuration of the present invention will be described in more detail.

The support layer 10 serves as a support for supporting most of the load acting on the top. The support layer 10 may be selectively adopted, for example, a cement extruded porous panel having a constant thickness, or a high density fiber reinforced cement board (CRC board), a fiber board (MDF), a PAPTICLE BOARD (PB), or the like.

Through-holes 110 may be formed in the support layer 10 at regular intervals from the top to the bottom. The elastic support 30 may be inserted into and fixed to the through hole 110 from the lower portion of the through hole 110. Therefore, a first space is formed between the support layer 10 and the concrete slab SL, which is a construction target surface. The space S1 may be formed.

When the first space S1 is formed between the support layer 10 and the concrete slab SL, even if an impact sound is transmitted from the upper portion of the support layer 10, the impact sound is not directly transmitted to the concrete slab SL side. The attenuation treatment may be performed by the air layer existing in the portion S1, and the improvement of the heating effect may be expected as the air convection by the air layer as described above existing in the first space S1.

The elastic support 30 also serves to support while dispersing the load transferred to the support layer 10 on the concrete slab (SL). The elastic support 30 applied to the present embodiment may be a configuration that can adjust the height according to the operation of the contractor, accordingly spaced apart from the concrete slab (SL) by adjusting the height of the elastic support (30). The separation distance of the support layer 10 and the horizontality of the support layer 10 may also be adjusted.

With reference to Figures 3 to 5 will be described in more detail with respect to the elastic support applied to this embodiment.

Figure 3 is an enlarged view of the main portion of the present invention showing a state in which the elastic support is installed on the support layer, Figure 4 is a perspective view of the elastic support applied to the embodiment of the present invention. 5 is an exploded cross-sectional view of the elastic support shown in FIG.

3 to 5, the elastic support 30 applied to the present embodiment, the support layer 10 before installing the heat reflector 40 (see FIGS. 1 to 2) on the support layer 10. The tool is inserted into the elastic support 30 side through the through hole 110 formed in the for example, has a configuration that can individually adjust the height as a hexagon wrench, through the height adjustment concrete slab (SL) and the support layer (10). The separation distance and the degree of horizontality can be adjusted.

In order to implement a height-adjustable structure, the elastic support 30 may have a configuration in which the height adjustment screw 320 is coupled to the center of the semi-spherical base portion 310. The support portion 310 may have a fastening surface 312 having a female thread formed at the center thereof, and a hollow hollow fitting protrusion 314 may be integrally extended to an upper portion of the fastening surface 312. have. And the height adjustment screw 320 may be a configuration in which a male thread is screwed to the fastening surface 312 of the support portion 310 on the outer surface.

A polygonal groove 322 for inserting a tool, for example, a hexagonal groove, is inserted into the head of the height adjusting screw 320 so as to be engaged with the tool inserted into the elastic support 30 through the through hole 110. This can be formed. In this case, the polygonal groove 322 may be exposed to the outside of the support layer 10 through the through hole 110 before the heat reflective material 40 is constructed.

Accordingly, when the tool is rotated clockwise or counterclockwise in a state of biting a tool, for example, a hexagon wrench, through the through hole 110, the height adjusting screw 320 for the support part 310. The fastening force of the) may be adjusted, and through this process, the height and horizontality of the support layer 10 spaced apart from the concrete slab SL can be adjusted accordingly.

On the outer surface of the fitting protrusion 314 formed on the supporting part 310, an uneven surface (not shown) that is continuous in the circumferential direction of the fitting protrusion 314 may be formed. As such, when the uneven surface is formed on the outer surface of the fitting protrusion 314, the fitting protrusion 314 may be inserted into the through hole 110 with a solid binding force due to the uneven surface, thereby preventing it from being lost. That is, in order to adjust the height of the elastic support 30 by rotating the height adjustment screw 320 as described above, the support portion 310 and the height adjustment screw 320 can be prevented from being rotated together.

When the height adjustment screw 320 is in direct contact with the concrete slab (SL) that is the installation target surface, the impact force transmitted through the support layer 10 can be transmitted as it is to the concrete slab (SL) through the height adjustment screw (320). have. Therefore, an elastic pad 330 having a damper function for absorbing and attenuating the impact force may be installed at the lower end of the height adjusting screw 320.

For assembling the elastic pad 330, an assembly groove 324 may be formed at a predetermined depth from the bottom of the height adjustment screw 320, the elastic pad 330 is coupled to the assembly groove 324 The protrusion 332 may be formed to protrude. In addition, an elastic washer 340 may be interposed between the support layer 10 and the elastic support 30.

On the other hand, the heat reflector 40 may be provided in a layer on the support layer 10 as shown in Figures 1 to 2. Such a heat reflecting material 40 may be a heat reflecting material having a heat insulating function and a shock absorbing function at the same time. For example, a heat reflector 40 having a configuration in which a heat reflector of a metallic material is attached to an elastic material surface such as urethane or rubber may be applied.

When the heat reflecting material 40 is installed on the support layer 10 as described above, a double heat insulation structure can be formed together with the buffer insulation layer 20 to be described later, in particular, the heat of the heating pipe 25 is lowered to the support layer 10. The reflection may be made back to the buffer insulating layer 20 side without being conducted, thereby more effectively preventing heat loss conducted and lost through the concrete slab SL during the heating process.

Damping member 50 in the length or width direction of the heat reflector 40 may be installed at regular intervals on the heat reflector 40, and thus, between the buffer insulating layer 20 and the heat reflector 40 to be described later The second space S2 for sound insulation may be formed. In this case, the damping member 50 may be, for example, a compression felt, a dustproof rubber or a synthetic resin having a predetermined thickness and width.

When the damping member 50 is installed above the heat reflection member 40 as described above, the damping function of the damping member itself and the sound insulation function of the second space S2 may be used, and the impact force transmitted from the heat reflection member 40 and the impact thereof. The noise can be blocked and attenuated reliably so that the cozy ondol structure can be realized.

The buffer insulation layer 20 may be installed in layers on the damping member 50. The buffer insulation layer 20 may be a light insulating material having a buffer function and a heat insulation function at the same time, for example, styrofoam, and a heating pipe 25 for heating implementation may be piped on the buffer insulation layer 20.

In the drawings, reference numeral 80 denotes a wire mesh installed between the buffer insulating layer 20 and the finishing mortar layer 60.

Subsequently, the heat reflection material 40 is laid on the support layer 10, and the damping member 50 is installed at regular intervals thereon. When the installation of the damping member 50 is completed, the buffer insulation layer 20 is formed by using an insulating material such as styrofoam on the damping member 50, and the damping layer 20 and the heat reflection material 40 are damped. A certain space (second space portion S2) is formed by the member 50.

After constructing the buffer insulation layer 20, the wire mesh 80 is laid thereon, and the heating pipe 25 is arranged in a zigzag form, so that a continuous heating path is formed. When the piping of the heating pipe 25 is completed, the ocher mortar or cement mortar is poured over the wire mesh 80 to form a finishing mortar layer 60.

After a certain period of time, when the ocher mortar or cement molybdenum is sufficiently cured to form a finishing mortar layer 60, the surface layer is finally covered by covering the floor finishing material 70 such as foamed vinyl-based flooring or wood flooring thereon. The construction can be completed.

Therefore, it is possible to implement the floor shock sound blocking structure that can effectively cope with the load and impact energy to reduce the noise between the floor more efficiently.

In addition, according to the blocking structure according to the present embodiment, by forming a heat reflecting material and a buffer insulating layer having a heat reflection function in the middle, it is possible to more effectively prevent the heat loss conducted and lost through the concrete slab during the heating process energy efficiency It is possible to implement a floor shock sound blocking structure that can be further improved.

Also, in the construction, as in the first floor construction using a buffer insulation layer such as a support layer and styrofoam, the construction is carried out by a semi-wet method in which a finishing mortar layer is formed by pouring ocher mortar or cement mortar on the dry construction after dry construction. As a result, unlike the wet method, which relies solely on conventional mortar casting, the air according to its construction can also be shortened.
