Description

Semi-dry interlayer noise cushioning structure and construction method thereof {fanel for sound insulation}

The present invention relates to an interlayer noise buffer structure, and more particularly, to minimize the resonance phenomenon by effectively absorbing the vibration noise, and even if the smoothness of the slab is poor, all the anti-vibration rubber provided on the lower part of the panel is automatically in close contact during construction. The present invention relates to a semi-dry interlayer noise buffering structure that prevents the normal lifting phenomenon and its construction method.

In general, in order to prevent inter-floor noise during slab construction of multi-family buildings, inter-floor noise prevention panels are installed in the slab to minimize the transmission of the impact sound generated from the upper floor to the lower floor.

These interlayer noise prevention panels have been applied by the present applicant and registered as Nos. 10-1301550 and 10-1666888, and the structure thereof is as follows.

In the interlayer noise prevention panel in which a plurality of support parts are integrally provided at the lower part of the main body, a plurality of elastic bands protruding downward and then protruding upward are arranged in a circular shape, and a support projecting downward at the ends of these elastic bands. A protrusion and a support rod protruding upward are formed, and the support protrusion protrudes from the bottom of the elastic band, and the support rod is installed close to the bottom of the upper concrete installed on the upper end, so that when a heavy load occurs, the upper end of the support rod is It is a structure that touches the bottom.

The interlayer noise prevention panel made of such a structure has its own elasticity and has a support bar on its upper part, effectively intercepting a small impact sound and generating a large impact. As the upper concrete touches the end, it prevents further descending, thereby preventing deformation of the support and preventing cracking of the upper concrete. In addition, by forming a support part with a plurality of elastic bands and protruding the support protrusion under the body, the impact sound is first exhausted by the main body and the second is exhausted by the support part. It has the effect of minimizing the transmission of impact sound by being exhausted

However, the conventional interlayer noise prevention panel has a disadvantage in that it cannot effectively block air vibration noise generated in the space between the panels and cannot block moisture generated from the floor. In addition, when the slab floor is depressed or protruded and the smoothness is poor, a phenomenon in which the support rod floats from the slab floor occurs, and thus, there is a problem that a crack occurs in the concrete placed on the upper part.

In addition, there is a problem in that it is not possible to use brackets that can walk without affecting the mortar that is poured when placing the mortar because the insulating material is located on the upper part of the interlayer noise prevention panel (shoes with a large number of long and thin vertical bars underneath). . That is, in the case of using brackets, there is a problem in that the brackets cannot be used because the insulator is drilled and inserted so that it is difficult to walk through and difficult to walk, and a hole is generated in the insulation.

As shown in these drawings, the semi-dry interlayer noise buffer structure according to the present invention includes an air cap (AC) spreading on the slab floor (S) having a plurality of partitioned closed spaces; Side cushioning material (F) installed at the edge of the slab floor (S); A panel 10 formed in a rectangular plate shape that is continuously coupled in all directions, and a plurality of cylinders 20 penetrating vertically and downwardly protruding downward at regular intervals, and installed on an upper portion of the air cap AC; An anti-vibration rubber 30 inserted into the lower part of the cylinder 20 and mounted on the upper surface of the air cap AC; An insulating material 40 having a plurality of insertion holes corresponding to the cylinder 20 formed therein, inserted into the cylinder 20 and installed in close contact with the lower portion of the panel 10; A hot water pipe (P2) and a direct water pipe (P1) installed between the heat insulating material 40 and the air cap (AC); A heating pipe (P3) fixedly installed on the panel 10; And a mortar (M) that fills the heating pipe (P3) and is poured over the panel (10). Includes.

The air cap AC has a structure having a plurality of enclosed spaces. In more detail, an upper film layer, a lower film layer, and a plurality of embossed layers each having a sealed space partitioned between the upper film layer and the lower film layer. This air cap AC has a cushion and is pressed by an external force. The air cap (AC) of this structure is spread and installed on the slab floor (S), thereby effectively blocking air vibration noise generated in the space between the panel 10 and the slab floor (S), minimizing resonance, and Block moisture from the floor.

The side cushioning material (F) is installed at the edge of the slab floor (S), that is, at a corner where the slab floor (S) and the wall surface meet. The side cushioning material (F) is processed in the form of a sponge, and a ventilation groove is formed in a portion in contact with the slab floor (S) and the wall surface. This side cushioning material (F) prevents the impact sound from being transmitted through the wall.

The panel 10 is formed in a rectangular plate shape, is continuously adhered to each other in all directions, and assembled, and a plurality of reinforcing ribs 11 are protruded in a grid shape on the upper surface. Under the panel 10, a cylinder 20 protruding downward is formed to space the panel 10 apart from the slab floor S by a predetermined distance.

The cylinder 20 is formed in a cylindrical shape, upper and lower, that is, vertically penetrating, and the upper part is wide and the lower part is formed in a narrow two-stage with respect to the middle, so that when the panel 10 is stacked, the lower part of the cylinder 20 It is inserted into the top of the cylinder 20 of the panel 10 and overlapped. The anti-vibration rubber 30 is inserted in the lower part of the cylinder 20 to minimize the transmission of the impact sound generated from the upper part to the lower part.

The anti-vibration rubber 30 is formed in a cylindrical shape and is inserted and installed from the lower portion of the cylinder 20. The anti-vibration rubber 30 includes an insertion portion 31 inserted into the cylinder 20 and an end portion 32 formed under the insertion portion 31 and exposed to the outside. The distal end 32 is formed with a larger diameter than the insertion part 31 so that the distal end 32 is caught at the lower end of the cylinder 20 so that it is not inserted any more.

In addition, the cylinder 20 forms an inward flange 21 at the inner periphery, and a stepped 22 protruding downward from the inner periphery of the inward flange 21, and the vibration-proof rubber 30 is an insert 31 ) Protruding upward from the upper edge of the inward flange 21 to form an elastic portion 33 interposed between the stepped 22 and the inner wall of the cylinder 20. The elastic portion 33 of the vibration-proof rubber 30 is formed thin and has its own elastic restoring force. When the cylinder 20 is inserted, the elastic portion 33 is corrugated and crushed while being positioned between the stepped 22 of the inward flange 21 and the inner wall of the cylinder 20 to form a watertight coupling. Therefore, when the mortar (M) is placed on the top of the panel (10), the mortar (M) flowing into the cylinder (20) does not flow out to the bottom by the elastic portion (33).

In addition, the anti-vibration rubber 30 has a plurality of ring-shaped protrusions 34 protruding in several layers on the outer periphery of the insertion portion 31 so as to be in close contact with the inner periphery of the cylinder 20. The anti-vibration rubber 30 is inserted into the cylinder 20 by the ring-shaped protrusion 34. However, it is designed so that the anti-vibration rubber 30 can rise and fall by an external force. Due to this structure, when there is a depressed part due to poor smoothness of the slab (S), the mortar (M) poured into the upper part of the panel 10 presses the vibration-proof rubber 30 by its own load, and thus the vibration-proof rubber 30 Descends and comes into close contact with the depressed slab floor (S).

The anti-vibration rubber 30 may be inserted and assembled from the upper portion of the panel 10 when assembling the panel 10. That is, in the process of laminating the panel 10 molded by an injection machine, if the vibration isolating rubber 30 is inserted from the top of the cylinder 20 of the molded panel 10, the inserted vibration isolating rubber 30 is When the other panel 10 is mounted on the inward flange 21 and the other panel 10 is stacked, the cylinder 20 of the panel 10 to be stacked is inserted into the cylinder 20 of the panel 10 and the anti-vibration rubber 30 already inserted. ) Of the insertion part 31 is automatically inserted into the cylinder 20 and assembly is made. When the laminated panels 10 are lifted one by one during construction, the anti-vibration rubber 30 is lifted in a state assembled to the cylinder 20.

In addition, the cylinder 20 has a plurality of hook protrusions 23 formed at the outer periphery. The hook protrusion 23 gradually protrudes in the lateral direction toward the top and is formed in a triangular cross-sectional area forming a horizontal surface on the upper surface. This is to prevent the insulation 40 installed under the panel 10 from being separated from the panel 10. The heat insulating material 40 has a plurality of through-holes into which the cylinder 20 is inserted, and the cylinder 20 is inserted into the through-hole of the heat insulating material 40 when the heat insulating material 40 is in close contact with the lower portion of the panel 10. At this time, the hook protrusion 23 is embedded in the inner wall of the through-hole of the insulating material 40 to prevent separation of the insulating material 40.

On the other hand, the panel 10 is provided on two adjacent sides of the panel 10, the support portion 12 made of a'U'-shaped cross-sectional area so that the slot groove 13 is formed between the two sidewalls connected to the lower part, A fitting portion 14 provided vertically downward from the other two sides of the panel 10 and vertically inserted into the support portion 12 of the other panel 10, and a plurality of fitting portions 14 formed on one side of the fitting portion 14 A hook portion 15 and a plurality of locking grooves 16 formed on one side of the support portion 12 and into which the hook portion 15 is inserted and locked are formed.

The support part 12 is formed to be elongated on two adjacent sides of the panel 10, and has a'U'-shaped cross-sectional area so that a slot groove 13 is formed between both side walls connected to the lower part. The upper end of one side wall of the support part 12 is integrally connected with the panel 10, and the other end has its own elastic force, so that it is widened or narrowed by an external force and then restored to its original state. The spacing of the slot grooves 13 of the receiving part 12 is formed equal to the thickness of the fitting part 14.

The fitting portion 14 is provided vertically downward from the other two sides of the panel 10 and is inserted into the slot groove 13 of the receiving portion 12 of the other panel 10. Here, the fitting portion 14 forms a plurality of hook portions 15 in order to prevent detachment while being inserted into the support portion 12. The hook portion 15 is formed to have a cross-sectional area of an inverted triangle that becomes narrower toward the bottom.

In addition, the receiving portion 12 has a plurality of locking grooves 16 into which the hook portions 15 are inserted and locked to correspond to the hook portions 15 on one side thereof. Accordingly, the fitting portion 14 inserted into the receiving portion 12 is not separated from the receiving portion 12 at the same time as the hook portion 15 is inserted into the locking groove portion 16.

On the other hand, the support portion 12 forms a plurality of spacing ribs 17 connecting both sidewalls to each other, and the fitting portion 14 forms a groove 18 corresponding to the spacing ribs 17. Here, the concave groove 18 is gradually widened toward the entrance so that it is easy to insert the gap maintaining flesh 17. The gap maintaining flesh 17 prevents the spreading of the support part 12 while keeping the distance between both side walls of the support part 12 constant. In addition, as the gap maintaining flesh 17 is positioned in the groove 18, the positions of the hook portion 15 and the locking groove portion 16 are automatically aligned while preventing lateral movement between the panels 10.

In addition, mounting portions 19 lower than the upper surface of the panel 10 are formed on two sides of the panel 10 on which the support portions 12 are formed, so that one end of the other panel 10 is placed and assembled. In this way, when the other panel 10 is seated on the seating portion 19, the upper surfaces of both panels 10 are installed in the same plane. When the seating portion 19 is formed, the receiving portion 12 is formed from the seating portion 19.

Finally, the panel 10 may form a plurality of pin holes (H), and the heating pipe may be fixed to the pin hole (H) with a U clip (U). The pin hole (H) is not penetrated, and a thin blocking film is formed in the middle. When the U clip (U) is inserted, the blocking film is pierced and the U clip (U) is inserted and fixed. The pin hole (H) where the U clip (U) is not installed prevents the mortar from leaking by maintaining the blocking film.

The construction method of the semi-dry interlayer noise buffer structure according to the present invention made of such a structure includes the steps of disposing an air cap (AC) having a plurality of partitioned closed spaces on the slab floor (S) (ST100); Installing a hot water pipe (P2) and a direct water pipe (P1) on the air cap (AC) (ST200); Attaching the heat insulating material 40 to the lower part of the panel 10, and combining the anti-vibration rubber 30 from the lower part of each cylinder 20 (ST300); Installing a side cushioning material (F) on the edge of the slab floor (S) (ST400); Step of continuously assembling and installing the panel 10 to which the heat insulating material 40 and the anti-vibration rubber 30 are combined in the vertical and horizontal direction on the upper part of the air cap AC (ST500); Fixing and installing the heating pipe P3 on the upper part of the panel 10 (ST600); Placing and curing mortar (M) on the top of the panel 10 (ST700); Includes.

[Air cap installation steps]

First, install an air cap (AC) on the slab floor (S). The air cap (AC) is supplied in the form of a roll, spread and installed on the front of the slab floor (S), and the boundary of the air cap (AC) is integrated by attaching a tape (ST100).

[Installation stage of hot water pipe and direct water pipe]

Install the hot water pipe (P2) and the direct water pipe (P1) on the upper part of the air cap (AC). At this time, the hot water pipe P2 and the direct water pipe P1 are prevented from interfering with the anti-vibration rubber 30 when the panel 10 to be described later is installed (ST200).

[Panel, insulation, vibration-proof rubber assembly stage]

When the installation of the hot water pipe (P2) and the direct water pipe (P1) is completed, the heat insulating material 40 and the anti-vibration rubber 30 are assembled to the panel 10. First, the heat insulating material 40 is attached to the lower part of the panel 10, where the heat insulating material 40 has a through hole corresponding to the cylinder 20 of the panel 10, and the cylinder 20 is inserted and attached to the through hole. do. In this process, the hook protrusion 23 formed on the cylinder 20 is stuck in the through hole of the heat insulating material 40, so that the heat insulating material 40 attached to the panel 10 is not removed.

Next, the anti-vibration rubber 30 is inserted from the bottom of the cylinder 20 of the panel 10. At this time, the elastic part 33 of the anti-vibration rubber 30 is corrugated and crushed while being located between the stepped 22 of the inward flange 21 and the inner wall of the cylinder 20 when the cylinder 20 is inserted, thereby forming a watertight coupling. Therefore, when the mortar (M) is placed on the top of the panel (10), the mortar (M) flowing into the cylinder (20) does not flow out to the bottom by the elastic portion (33).

In the step of assembling the insulation material 40 and the anti-vibration rubber 30 on the panel 10, it is preferable to assemble in a factory in advance so that they can be directly installed on site. (ST300)

[Side cushioning material installation step]

The side cushioning material (F) installation step is to install the side cushioning material (F) on the edge of the slab floor (S). The side cushioning material (F) is supplied in the form of a strip, and the corner area where the slab floor (S) surface meets the wall surface. Is installed in At this time, it is installed so that the side on which the ventilation groove is formed faces the slab floor (S) and the wall. The side cushioning material F may be attached by an adhesive or may be fixed by pressing the edge of the panel 10 when constructing the panel 10 (ST400).

[Panel installation steps]

When the installation of the side cushioning material (F) is completed, the panel 10 to which the insulation material 40 and the anti-vibration rubber 30 are combined is sequentially seated and installed from the corner.

That is, first, one panel 10 is seated on the slab floor S. At this time, the support part 12 is positioned in a direction to be continuously installed. Next, the panel 10 to be installed is positioned above the side of the panel 10 that is already installed, and the fitting portion 14 is positioned above the support portion 12.

In this state, the panel 10 to be installed is lowered and the fitting portion 14 is inserted between the slot grooves 13 of the supporting portion 12, but the gap maintaining flesh 17 through the groove 18 of the fitting portion 14 ) Is positioned and inserted. When the fitting portion 14 is gradually inserted into the slot groove 13, one side wall of the supporting portion 12 is retracted by the hook portion 15 protruding from the fitting portion, and the slot groove 13 is opened, and the hook portion ( As soon as 15) is positioned in the locking groove 16, the hook 15 is inserted into the locking groove 16, and the slot groove 13 is narrowed again by the self-elastic restoring force of the support 12. In such a state, both side walls of the receiving unit 12 press both sides of the fitting unit 14 and the hook unit 15 is engaged in the catching groove 16, so the fitting unit 14 from the receiving unit 12 ) Does not escape. That is, both panels 10 are assembled to each other to maintain a connected state.

In this way, the panel 10 is continuously assembled in the lateral direction to complete the construction. When the installation of all the panels 10 is completed, the boundary between the panels 10 is assembled without a gap by the coupling of the support 12 and the fitting 14 (ST500).

[Heating pipe installation stage]

When the installation of the panel 10 is completed, the heating pipe P3 is fixed to the panel 10 in a desired shape by using a U clip U on the upper part of the panel 10. If the heating pipe (P3) is located above the pin hole (H) of the panel 10 to be installed and the U clip (U) is forcibly inserted into the two pin holes (H), the blocking film is opened and the U clip (U) is inserted and Fixation is made. In this way, U clips (U) are fixedly installed at regular intervals along the heating pipe (P3). The pin hole (H) where the U clip (U) is not installed prevents the mortar from leaking by maintaining the blocking film. (ST600)

[Place mortar and curing stage]

When the construction of the heating pipe (P3) is completed, pour mortar (M) on the top and pour it. In this process, the mortar (M) is introduced into the upper portion of the cylinder 20, and the mortar (M) introduced into the cylinder 20 is filled up to the upper surface of the anti-vibration rubber (30).

On the other hand, the anti-vibration rubber 30 located in the recessed portion due to the poor smoothness of the slab (S), the mortar (M) poured on the top is introduced into the cylinder (20), and is dust-proof by the own weight of the introduced mortar (M). By pressing the rubber 30, the anti-vibration rubber 30 descends until it reaches the slab floor (S). In this way, all the anti-vibration rubber 30 is in close contact with the slab floor (S) so that the cured mortar (M) has the effect of not generating cracks.

And as the elastic portion 33 of the anti-vibration rubber 30 is located between the stepped 22 of the inward flange 21 and the inner wall of the cylinder 20, the mortar (M) is It does not flow out to the bottom by the elastic portion (33).

In addition, assembly without gaps between the panels 10 is made by the support part 12 provided at the edge of the panel 10 to prevent the mortar M from leaking, and for this reason, it is necessary to attach a tape between the panels 10 none.

Not only that, since there is no need for aerated concrete, the load on the building is reduced, the finishing work is shortened, and the cost is reduced. In addition, since the heat insulator 40 is installed under the panel 10, it is possible to use a bracket when placing mortar, so workability is also excellent. (ST700)
