Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a floor impact sound reducing floor structure reinforcing apparatus having an elastic member for a building structure, and a floor structure reinforcing apparatus having the floor impact sound reducing floor structure reinforcing apparatus.

More particularly, the present invention relates to a floor impact sound reducing floor impact sound generated by a resident of an upper floor in a building structure such as a dwelling house, The present invention relates to a floor impact sound reduction and floor structure reinforcing apparatus having an elastic member for a building structure and a method of constructing the same.

At present, in Korea, many apartment houses represented by apartments are constructed, and the inconvenience caused by the floor noise and vibration of these apartment houses is pointed out as a peculiar disadvantage of the apartment house only. Particularly, in the case of apartment houses where the walls and floors are to be shared with neighboring households, floor impact sounds applied to the floor are transmitted to the lower floor due to walking in the room, jogging of children, falling of objects, Interstep noise and vibration are causing discomfort among neighbors who want to relax in a pleasant and quiet environment.

As a result, the government revised the "Housing Construction Standards, etc." and revised the floor impact sound standard to reduce floor noise among apartment buildings, especially apartments. According to these regulations, the standard of the floor-to-floor impact sound of the apartment house is divided into a light impact sound to the extent that a small object falls and a heavy impact sound to the degree that a child can play it. These floor impact sound standards are such that the sound of the table chairs is not heard downstairs, and the sound of children running is not offensive.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a floor structure system for floor impact sound reduction according to the prior art; FIG.

Referring to FIG. 1, a floor structure system for reducing a floor impact sound according to the related art includes a concrete floor slab 12 constructed with a predetermined thickness, and a heat insulating material or a cushioning material, which are sequentially installed on the concrete floor slab 12, Lightweight foamed concrete 22, bottom finishing mortar 23 and bottom finishing material 24, respectively. Here, reference numeral 11 denotes a wall, and reference numeral 13 denotes a facility pipe.

However, the floor structure system according to the related art can improve the effect of reducing the adiabatic effect and the light impact sound, but increases the construction cost and delays the air. Further, in the floor impact sound reduction, It is revealed that there is no. In addition, most of apartment houses which are not legally regulated against floor impact sound have not been considered for floor impact sound at all.

Meanwhile, in order to improve the noise problem of the above-mentioned floor structure system, a floor cushioning material using a special anti-vibration material such as an anti-vibration rubber pad having a thickness of 10 mm to 50 mm has been recently developed Although the vibration caused by the impact applied to the upper layer is somewhat blocked by installing the floor structure system, it has been found that such a floor structure system does not have a great effect on reduction of heavy impact sound.

On the other hand, in most current construction sites, it is common to apply a standard floor structure to meet legal requirements for heavy impact sound. Specifically, the standard floor structure increases the slab thickness in order to reduce the floor impact sound. For example, in the case of the wall type structure, the concrete floor slab thickness is set to 210 mm. However, since the standard floor structure is generally constructed to have a thickness larger than the slab thickness required for structural safety, it is necessary to increase the amount of concrete used, increase the weight of the building, There is a problem.

As a prior art for solving the above-mentioned problems, Korean Patent No. 10-1045403 discloses an invention entitled " Structure for preventing building-to-building noise ", which will be described with reference to Fig.

2 is a schematic cross-sectional view of a building in which a structure-borne interlayer noise preventing structure according to the related art is installed.

Referring to FIG. 2, an interlayer noise preventing structure for a building according to the related art is provided with an interlayer structure between the walls 11 so as to partition the upper and lower layers. The interlayer structure includes a concrete slab 12, a cushioning material 31, a lightweight foamed concrete 32, a closed mortar 33, and a floor finish 34. At this time, a heat insulating material may be used instead of the buffer material 31, and the interlayer structure may be a standard floor structure.

A ceiling 35 is spaced below the concrete slab 12 and a ceiling space is defined by the ceiling 35 and the concrete slab 12. At this time, the building interlayer noise preventing structure 40 is disposed in the ceiling space.

The building interlayer noise preventing structure 40 includes a membrane sheet 41, a sag preventing member 42, and a fixing member 43. The membrane sheet 41 is spaced apart from the concrete slab 12 and the ceiling 35 and dissipates the noise transmitted from the upper layer through the interlayer structure by membrane vibration, It is prevented from being transmitted to the lower layer under the ceiling. The membrane sheet 41 may be formed of various materials and has a flexible structure, for example, a PVC film.

According to the structure-to-building noise preventing structure according to the related art, since the energy of the noise transmitted from the upper layer is converted into vibration energy by the membrane sheet and then dissipated, the sound insulating performance of the interlayer noise can be improved.

However, in the case of the interlayer noise preventing structure for a building according to the related art, there is a problem that a separate interlayer noise preventing structure 40 for a building should be installed between the concrete slab 12 and the ceiling at the time of building construction.

On the other hand, as described above, the problems caused by the floor impact sound are becoming a social concern in existing apartment houses and the like. Particularly, reduction measures for heavy impact sound remain in the way of increasing the floor slab thickness, and the floor slab thickness of the apartment house for reducing floor impact noise is currently required to be 210 mm or more. Particularly, in the case of existing houses, the floor slab thickness is often less than 150 mm, and improvement of floor impact sound, in particular, heavy impact sound is required.

On the other hand, there is a plan to reduce the floor impact sound for existing houses by installing additional H beams or concrete to reinforce the strength of the bottom plate, and FRP bonding method. However, this method is limited in installation, or it is troublesome to increase the cost and to reconstruct the structural frame.

Therefore, the existing floor slab thickness is thin, or it is a building installed before the floor impact sound reference, or a space that does not damage the structure such as the existing wall or the bottom plate by the simple construction and low cost method for the space where the problem is caused by the noise of floor impact sound A technique capable of reducing the floor impact sound is needed.

On the other hand, as a prior art for solving the above-mentioned problems, Korean Patent No. 10-1024059 discloses an invention entitled " Floor impact sound reduction structure using an interior and exterior cover member ", which is shown in FIGS. 3A and 3B .

3A and 3B are an exploded perspective view and a side sectional view, respectively, of a floor impact sound reduction structure using an interior and a cover member according to a conventional art.

3A and 3B, a floor impact sound reducing structure 50 using a cover member for interior and interior according to the related art is fixed at a predetermined distance in the lower portion of the slab 12, A connecting member 60 composed of a horizontal part 61 located on the side of the horizontal part 61 and a vertical part 62 extending vertically downward from one end of the horizontal part 61; A cover member (51) having both ends fixed to the other end of the horizontal portion (61) so as to surround a pair of adjacent connecting members (60), and having through holes at both ends thereof; A nut coupled to an inner portion of the cover member having the through-hole formed therein, the nut being threaded along an inner circumferential surface thereof; And a bolt 52 which is fastened to the nut through the through hole and presses the other end of the horizontal part 61 to connect the cover member 51 to the connecting member.

The connecting member 60 is a member connecting the slab 12 and the cover member 51 protruding to the lower portion of the ceiling 70 and is directly coupled to the lower surface of the slab 12. [ The connecting member 10 is composed of a horizontal portion 61 and a vertical portion 62 to maintain the shape of the cover member 51 and to resist deformation of the slab 12, It can be made in advance in the factory.

The connecting member 60 includes a threaded anchor (not shown) having one end inserted into the slab 12 and the other end passing through the horizontal portion 61 of the connecting member 60 and coupled with the nut 82 below the horizontal portion 61 81). ≪ / RTI > Therefore, a hole for inserting the threaded anchor 81 can be previously drilled in the horizontal portion 61 of the slab 12 and the connecting member 60.

According to the floor impact sound reduction structure using the interior cover member according to the related art, it is possible to reduce the floor impact sound by improving the slab's secondary moment by increasing the moment of inertia of the slab in the apartment house remodeling and the like, It is possible to reduce the floor impact sound from the lower floor by the minimal remodeling work without any burden on the floor, ceiling and ceiling, and it is possible to construct the material by the field assembly only after preliminarily manufacturing the material in the factory, thereby improving the workability and quality.

However, in the case of the floor impact sound reduction structure using the interior cover member according to the related art, there is a problem that the structure reinforcement is limited because the cover member and the connecting member are simply fastened to the lower portion of the slab.

On the other hand, Korean Patent Registration No. 10-1482983 discloses an invention titled " a floor impact sound reducing apparatus for a building structure and a construction method thereof ", as another prior art, and is specifically described with reference to FIGS. 4 to 6 do.

The hinge connection member 140 is fastened between the fixed hinge 110, the transverse moving hinge 120, and the upper hinge 130 and connected to each other. Specifically, the hinge connection member 140 includes a first hinge connection member 141 connected between the fixed hinge 110 and the transverse movement hinge 120, the transverse movement hinge 120 and the upper hinge 130, And a third hinge connection member 143 connected between the fixed hinge 110 and the upper hinge 130. The second hinge connection member 142 may include a second hinge connection member 142,

The hinge support 150 is coupled to the fixed hinge 110 and the transverse moving hinge 120 to fix the fixed hinge 110 and move the transverse moving hinge 120 in a lateral direction. Here, the hinge support 150 may include a hinge support body 151, a fixed hinge fixing nut 152, and a force transmission nut 153.

[Floor Impact Noise Reduction and Floor Structure Reinforcement Apparatus with Elastic Members for Building Structures]

7 is an installation sectional view of a floor impact sound reduction and floor structure reinforcing apparatus having an elastic member for a building structure according to an embodiment of the present invention.

Referring to FIG. 7, the floor impact sound reducing floor structure reinforcing apparatus 300 having the elastic member for building structure according to the embodiment of the present invention is installed in the floor structure 220, The hinge joints 340, 341, 342, 343, and the elastic members 341, 342, 343, 343, 343, Wherein the first and second transverse movement hinges 310 and 320 and the upper fixation hinge 330 are connected to the first and second transverse movement hinges 310 and 320, Thereby forming a hinge structure. At this time, it is assumed that the thickness of the bottom plate 220 is 150 mm instead of 210 mm.

The floor impact sound reduction and floor structure reinforcing apparatus 300 having the elastic member for a building structure according to an embodiment of the present invention includes a triangle hinge structure 310, 320, 330 composed of three hinges, An elastic member 350 fastened between the transverse moving hinges 310 and 320, and a hinge support 360 supporting the triangular hinge structure.

The triangular hinge structure includes first and second transverse moving hinges 310 and 320 and an upper fixed hinge 330 and is disposed below the bottom plate 220. In this case, when the triangular hinge structure is installed, the first and second transverse movement hinges 310 and 320 are installed to move in the lateral direction on the hinge support 360, A force generated while moving to the upper or lower portion corresponding to the first and second lateral movement hinges 310 and 320 is transmitted to the bottom plate 220.

The hinge connectors 340 are fastened and connected to each other between the first and second transverse moving hinges 310, 320 and the upper fixed hinge 330, respectively. Specifically, the hinge link 340 includes a first hinge link 341 coupled between the first transverse hinge 310 and the upper fixed hinge 330, and a second transverse hinge 320, And a second hinge connector 342 connected between the upper fixing hinge 330 and the upper fixing hinge 330.

The elastic member 350 is preferably a material having elasticity, and is preferably an elastic body or a spring or rubber having restoring force, but the present invention is not limited thereto.

One side of the hinge support 360 is fastened to the first and second transverse moving hinges 310 and 320 to move the first and second transverse moving hinges 310 and 320 in a lateral direction. In addition, the other side of the hinge support base 360 is fixed to the support base fixing member 380. At this time, the hinge supporter 360 can be fixed on both sides, maintains the restoring force and supports the force, and the sectional shape of the hinge supporter 360 may be circular, cylindrical, angular, H or I-shaped.

The force transmitting plate 370 may be installed between the bottom plate 220 and the upper fixing hinge 330 to transmit a force to the upper or lower portion of the upper fixing hinge 330. [ The force transmitting plate 370 is formed in the form of a plate so as to stably transmit a force to push up the bottom plate 220 such as a slab or a beam on the upper fixed hinge 330, The vibration of the floor impact sound is reduced and the impact sound is absorbed by being integrated with the bottom plate 220 through a cushioning pad, an adhesive sheet, an adhesive, or a bolt (screw) joint.

The fixing member 380 fixes the other side of the hinge support 360 to be fixed to the bottom of the bottom plate 220. For example, the support fixture member 380 may be installed such that both ends of the hinge support 360 are fixed to the wall 210 on both sides of the building structure.

The floor impact sound reduction and floor structure reinforcing apparatus 300 having the elastic member for building structure according to the embodiment of the present invention may be installed in the bottom plate 220 or the slab in the upper ceiling of the space where the floor impact sound is severely generated, At this time, the force transmitting plate 370 is installed to face the bottom plate 220 or the slab, and pushes up the hinge support 360 from both sides or from the center to the upper side. Then, a force for pushing up the hinge support 360 and pushing up the hinge support 360 to the bottom plate 220 or the slab of the ceiling portion is transmitted to the elastic member 350.

The force transmitted to the elastic member 350 is pushed upward to increase the rigidity of the upper floor structure, and the elastic member 350 is stretched or shrunk, and a repulsive force of the same magnitude is generated. At this time, both sides of the hinge support member 360 are fixed to a wall, a column, or the like by the support member fixing member 380. Accordingly, the restoring force of the elastic member 350 transmits the force in the upper or lower direction of the force transmitting plate 370 to support the bottom structure and enhance the rigidity.

In the case of a floor impact sound reduction and floor structure reinforcing apparatus 300 having an elastic member for a building structure according to an embodiment of the present invention, for example, a hydraulic device or an electric lifting device, The hinge support 360 can be raised to an upper portion with a considerable force.

The triangular hinge structure also has three hinge structures of first and second transverse moving hinges 310 and 320 and an upper fixed hinge 330 and the first and second transverse moving hinges 310, 320, for example, the elastic member 350 may be rubber, spring, or the like, but is not limited thereto.

The floor impact sound reducing floor structure reinforcing apparatus 300 having the elastic member for building structure according to the embodiment of the present invention can be easily installed on the ceiling bottom plate of the space where the floor impact sound is generated, The floor impact sound generated by the floor impact sound can be reduced. The floor impact sound reducing and floor structure reinforcing apparatus 300 having the elastic member for building structure according to the embodiment of the present invention converts the vibration mode of the floor plate 220 when the floor impact sound occurs, The floor impact sound can be attenuated by inducing a change in the primary natural frequency of the floor impact sound.

8 is a schematic view illustrating a triangular hinge structure in a floor impact sound reduction and floor structure reinforcing apparatus having an elastic member for a building structure according to an embodiment of the present invention. FIG. 9A is a front view, FIG. 9B is a plan view, and FIG. 9C is a side view. FIG. 9A is a front view of the floor impact sound reducing floor structure reinforcing apparatus, .

In a floor impact sound reduction and floor structure reinforcing apparatus 300 having an elastic member for a building structure according to an embodiment of the present invention, as shown in FIG. 8 (a), among the three hinges constituting the triangular hinge structure The two hinges are first and second transverse moving hinges 310 and 320 that move laterally along the hinge support 360 and the other is composed of an upper fixed hinge 330 that transmits force. At this time, the hinge connectors 341 and 342 are coupled between the first and second transverse moving hinges 310 and 320 and the upper fixed hinge 330, respectively, and connected to each other.

As shown in FIG. 8 a), when a force is exerted by the lifting acting as a top, both first and second lateral moving hinges 310 The distance L between the force transfer plate 370 or the upper fixed hinge 330 and the first and second transverse moving hinges 310 and 320 or the hinge supports 360 (Height) decreases from H to H '.

At this time, the length of the elastic member 350 fastened between the first and second lateral movement hinges 310 and 320 increases from L to L ', and a restoring force or a repulsive force to be restored is generated, (L '→ L).

When the positions of the first and second transverse moving hinges 310 and 320 where the repulsive force is generated, which is the restoring force of the elastic member, are fixed, the force transmitting plate or the upper fixed hinge and both the first and second transverse moving hinges A force to restore the original length of the elastic member 350 is transmitted through the action of restoring H ', which is the interval (height) between the hinges 310 and 320 or the hinge support 360, That is, the force to increase from H 'to H does not increase to the bottom due to the position fixation of the hinge support 360 or the first and second lateral movement hinges 310 and 320, .

As a result, as shown in FIG. 8C, the structural performance of the bottom structure is increased by pushing upward the upper force transmitting plate 370 and supporting the upper bottom plate 220, And the rigidity of the bottom plate can be increased.

9 (a) to 9 (c), the floor impact sound reduction and floor structure reinforcing apparatus 300 having the elastic member for a building structure according to the embodiment of the present invention is fastened with a fastening member And the elastic member 350 may be provided on both sides of the hinge support 360.
