Description

TECHNICAL FIELD [0001] The present invention relates to a floor impact sound reducing apparatus for a building structure,

The present invention relates to a floor impact sound reducing apparatus, and more particularly, to a floor impact sound reducing apparatus capable of reducing floor noise, which is floor impact noise 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 reducing apparatus and a method of constructing a floor impact sound reducing structure of a building structure capable of supporting a bottom plate or reinforcing a structural performance of a bottom plate.

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.

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.

Meanwhile, FIG. 8 is a diagram illustrating a continuous formation of a triangular hinge structure in a floor impact sound reducing apparatus of a building according to an embodiment of the present invention.

The floor impact sound reducing apparatus of a building structure according to the embodiment of the present invention is characterized in that the force F1 or F3 is generated by horizontally moving the transverse moving hinge 120 in the triangular hinge structure as shown in Fig. The upper hinge 130 has a force F2 or F4 for pushing up or supporting the upper hinge 130. When the lateral hinge 120 is moved in a lateral direction away from the upper hinge 130, The upper hinge 130 is pulled downward or a downward tension is applied.

In other words, operation by the plurality of triangular hinge structures is performed only by connecting the hinge 110 at the distal end of the plurality of hinges to the fixed hinge 110 and connecting the remaining hinge to the transverse moving hinges 121 to 125, For example, a moving hinge + ... + Movable hinge + 'fixed hinge', and point or continuous point support can be changed to face support or line support. In other words, the overall area of the supporting points is increased to increase the supporting force of the bottom plate 220, and to provide a structural stability to the action of the force in the construction.

The floor impact sound reducing apparatus of a building according to an embodiment of the present invention includes a plate hinge 130 for reliably transmitting a force for pushing up a bottom plate 220 such as a slab and a beam on the upper hinge 130, Shaped force transmitting plate 160 can be additionally constructed so that the point support or continuous point support described above is changed to a face support or a line support manner.
