Hereinafter, with reference to the accompanying drawings a preferred embodiment of the interlayer sound insulation of the building structure according to the present invention will be described in detail. In the description of the present invention, a detailed description of the interlayer floor structure such as a known interlayer slab will be omitted.

The present invention relates to a sound insulation device provided between an interlayer slab and an upper floor floor structure of a building.

1 to 4, the sound insulation device includes a plurality of panels 100 and 100a and a dustproof pad 200 for placing the panels 100 at a predetermined height from the slab.

The panel 100 is formed of a synthetic resin material in a square shape in a plate-like structure, as shown in Figure 2 or 3, and maintains the same plane to form an interlayer floor structure when in close contact with each other, A plurality of downwardly open grooves 110 are formed, and the upper end of the dustproof pad 200 is fitted into the grooves 110.

There is no need to perform a separate bonding process using an adhesive or the like when the dustproof pad 200 is coupled, and the dustproof pad 200 is hermetically crimped to the panel groove 110 by simply being fitted.

At least four grooves 110 may be formed on the bottom surface of the panel 100 so that the grooves 110 may be stably positioned on the ground when the dustproof pad 200 is coupled.

In addition, seating jaws 120 having pinholes 122 are formed on both sides of one corner of the panel 100 in a stepped manner, and the other panel 100a is disposed on both bottom surfaces of the other corners corresponding to the corners. The mounting jaw 120 of the) is engaged to the mounting groove 130 and the mounting groove 130 in the pinhole 122 so that the panel 100, 100a to maintain the same plane when they are mutually coupled Pins 132 to be coupled are formed to protrude downward.

Here, the seating jaw 120 on both sides from the edge of the panel 100 is formed only to a position where both ends are spaced apart by the width of the seating jaw 120 than the end of the other corner, respectively, the panel 100 When the panel 100a and another panel 100a overlap each other, that is, when the seating groove 130 and the seating jaw 120 are coupled to each other, the panels 100 and 100a may be arranged in a horizontal and vertical direction.

Accordingly, the upper and lower gaps between the panels 100 and 100a may be blocked, and the pins 130 and the pinholes 122 may be easily coupled and fixed.

In addition, a plurality of grooves 140 for lowering the weight of the panel 100 are formed to be opened downward on the bottom surface of the panel 100, and at this time, the panel (through the rib between the grooves 140 and the grooves 140). The vertical strength of 100 is further improved.

In addition, the upper surface of the panel 100, the projection line 150 is formed to cross each other in an oblique direction to prevent the rolling during the installation of the floor structure.

5 to 11 is a view showing an embodiment of a dustproof pad according to the present invention.

As shown, the anti-vibration pad 200 is made of a solid or hollow circular member made of an elastic rubber material. In addition, the axial center is formed in the buffer space 210 is vertically penetrated or upwardly open to reduce the transmission of shock waves due to the minimization of the contact area, as well as the shock sound transmitted through the dust-proof pad filled with air In addition to absorbing effectively, the durability of the elastic force is enhanced to reinforce the buffering force and maintain a stable appearance when a load is generated.

That is, the buffer space 210, the air is filled therein to have a cushioning force when the shock occurs and to absorb the noise when the shock sound is transmitted.

In addition, even when the durability of the anti-vibration pad 200 decreases, the air filled in the inside ensures a support force when a load is generated, thereby maintaining the elastic force and rigidity of the anti-vibration pad.

In addition, the cushioning space of the vibration pad may be filled with a buffer material having excellent properties of absorbing shock and elasticity of the impact sound may be coupled to the lower groove of the pad.

As shown in Figure 5 to 9, the bottom surface of the vibration pad may be formed with a plurality of cushioning projections on the circumference.

As shown, when the bottom surface of the anti-vibration pad 200 is formed of a plurality of cushioning projections 222, the contact area between the sound insulation device of the present invention and the slab in the lower layer can be reduced to minimize the transmission of interlayer noise or impact sound. , Even if a load other than a vertical load is generated, the sliding protrusion may be prevented through the contact of the cushion protrusion formed on the bottom surface of the dustproof pad 200.

As illustrated in FIG. 7, the buffer space 210 is formed with a taper angle 220 having an upper inner diameter gradually larger than a lower inner diameter so that its inner circumferential surface can support an impact load, thereby minimizing contact area. Support for load is improved, resulting in structural stability. The dustproof pad of this structure can be suitably used for a building structure in which a large load is transmitted between floors.

FIG. 8 illustrates a curved portion 230 having an inner diameter up and down uneven shape as another example of the buffer space 210, which provides a multi-stage buffering force during shock load or shock wave transmission to completely absorb vibration and noise. do. The dustproof pad of this structure can be used suitably for building structures with high interlayer vibration.

10 and 11 illustrate another example of the anti-vibration pad 300. The buffer space 310 upwardly opened at the axial center is formed, and a plurality of cushioning protrusions 322 are formed at the lower end of the vibration pad 300. The cushion portion 320 of the material is to be combined.

When the protrusion is formed on the bottom surface of the anti-vibration pad, when the load is concentrated on the protrusion and a long time elapses after construction, the elastic force of the anti-vibration pad may decrease. To prevent this, the lower end 320 of the anti-vibration pad having the protrusion is formed. It may be made of a urethane material having excellent durability against elastic force. However, since the urethane material is a material that is more expensive than general rubber or synthetic resin material, it may be preferable in terms of cost to form the bottom part of the dustproof pad having protrusions formed thereon.

When the anti-vibration pad of such heterogeneous material is manufactured, it is preferable to mold one of the upper body or the cushion part 320 of the anti-vibration pad 300 and then combine the other.

The installation process of the interlayer sound insulation device of the building structure constituted as above will be described in detail with reference to the accompanying drawings.

After each of the anti-vibration pads 200 is fitted, the mounting grooves 130 of the other panel 100a correspond to the seating jaw 120 formed in one panel 100, and then the pins 130 and the pinholes 122 are aligned. ) To fit together to be assembled into a puzzle shape.

Between the mounting jaws coupled to each other in the assembling process is coated with an adhesive (for example, adhesive silicone, etc.) having a waterproof and soundproof function and then coupled to each panel by engaging. As a result, each panel is coupled between each other in a sealed form. As a result, the bonding force between the panels is strengthened, and the sound insulation and waterproof effect can be maintained even between the panels.

On the other hand, in the coupling between the panel 100, 100a, the installation of the anti-vibration panel 200 may be omitted on the mounting jaw 120 side of the mounting jaw 120, 120a is engaged with each other. This is because the seating jaw 120a engaged with the bottom may support the panel 100 of the seating jaw 120 engaged with the top. Installation in this way can reduce installation costs.

As described above, after the panel assembly step is completed, if the upper layer bottom structure is installed on the upper surface of the panels 100, the installation of the sound insulation device is completed.

As another example, after completion of the panel 100 structure, at least one sound insulation material layer 400 may be installed on an upper surface thereof, and a bottom structure may be installed on the upper surface of the sound insulation material layer 400.

That is, the sound insulation device in which the sound insulation layer 400 is installed performs floor interlayer slab formation step of the building structure during installation and successively closes the panel 100 and 100a in which a plurality of dustproof pads 200 are coupled to the bottom.

In addition, the shock-absorbing dustproof pad is provided with a buffer space for air filling inside, which not only absorbs shock sound but also maintains the elastic force of the dustproof pad even after a long period of construction. It is possible to maintain a buffer action without a volume change, and also to minimize the upper contact area of the dustproof pad has an effect that can further block the transmission of shock waves.

In addition, the anti-vibration pad is provided on the bottom of the cushion portion of the urethane material is a release material has the effect of minimizing the shock wave when the impact occurs. In addition, there is an effect that can further prevent the slip and shock wave transmission path through the contact of the cushion projection formed on the bottom of the cushion portion even if a non-normal load is generated.

In addition, the panels supporting the floor structure of the building can be stably assembled in a simple manner through the pinhole formed on the seating jaw and the pin formed on the bottom of the panel, and the process of joining the dustproof pad to the panel is simple without additional bonding process. It is effective to increase the work efficiency by fitting.
