[0001] FLOOR PANEL FOR SHUTTING NOISE BETWEEN STAIRS OF APARTMENT HOUSE [0002]

The present invention relates to a flooring for preventing noise between apartment houses, more particularly, a flooring for preventing noise between buildings in a building, which facilitates an assembly structure to shorten a construction time, .

In recent multi - storey multi - family apartment complexes such as apartments, the upstairs noise or impact noise is becoming a big social problem due to the interstate noise transmitted to the lower floor.

Interlayer noise is mainly caused by footsteps generated when moving in the living space of an upper-floor resident, or when the door is opened or closed, when an object hits the bottom of a moving object or the floor, or when the child runs or rolls.

This kind of interstory noise is caused by the very good attainment of solid solid such as concrete structure. If it is neglected, it will cause serious social problems such as neighboring brawls as well as human accidents. Therefore, thorough measures are required.

Therefore, it is essential that the construction of the interlayer noise preventing means capable of preventing the noise or the shock vibration is almost indispensable at the time of flooring of each floor of the multi-storey apartment building.

Korean Patent Registration No. 10-0741757 (Jul. 16, 2007) discloses an interlayer structure of a multi-storey building.

1, a panel 100 having a plurality of mesh holes 110 is bonded to a buffer member 400 using a nut 130 to form a buffer structure, It is installed between the foundation bottom layer of the multi-storied building and the upper end mortar layer so that the interlayer noise isolation and the insulation effect can be obtained.

However, the interlayer structure disclosed in FIG. 1 of the prior art is too complicated in structure, resulting in a high manufacturing cost due to a high manufacturing cost. Only through the cushioning member 400 formed of the anti-vibration rubber constituting the leg, It is impossible to completely block the interlayer noise, and in particular, when the rubber is hardened, the interlayer noise is concentrated through the portion, and thus, there is a limit to cause another secondary noise There is an urgent need for improvement.

In addition, since there is no means by which the plurality of panels 100 can be coupled together when the panel 100 is laid on the installation surface, the panels 100 play separately, making subsequent construction difficult, have.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIGS. 2 to 4, the flooring for preventing noise between apartment buildings according to the present invention is installed on the upper surface of a floor slab, which is a concrete constituting each indoor floor of the apartment house.

A floor having a heating function such as a hot water panel is installed on an upper surface of the flooring for preventing noise between the apartment houses.

Therefore, the flooring for preventing noise between the layers of the building according to the present invention can not be as thick as possible, and most preferably should be kept within a range of 3-5 cm. However, it is quite natural that the thickness can be increased or decreased according to need, and the flooring can be installed upside down if necessary.

However, for the sake of convenience of explanation, it is shown relatively enlarged in the drawings.

Particularly, the flooring for preventing inter-layer noise has an anchor structure which is not interfaced with the floor and has adjacent anchors which are connected to each other by having a fitting-type, more precisely a side- So that it is possible to perform precise construction.

More specifically, the flooring for preventing noise between the layers of the building according to the present invention includes the lower housing 10.

The lower housing 10 is formed in a rectangular box shape having an opened top, and is configured to receive something therein.

Particularly, the open upper surface of the lower housing 10 is provided with a plurality of, preferably four, fitting pieces 12 which are separated from each other and separated from each other without interfering with each other.

The fitting piece 12 has a width smaller than the width of the open upper surface of the lower housing 10 and protrudes at a predetermined height.

A plurality of through holes 14 are formed at a predetermined interval around the lower housing 10 so that the through holes 14 communicate the inside and the outside of the housing 10, Or sound is distributed smoothly.

In addition, a fastening boss 16 protrudes at a certain height from the bottom center of the lower housing 10.

The fastening boss 16 is formed with a thread on an inner diameter thereof, and is fastened or loosened by fastening a fastening bolt 70 to be described later.

Particularly, since the lower housing 10 itself has a function of buffering and absorbing sound and has a constant strength enough to maintain its shape, it is manufactured by molding a mixture of polyurethane foam and polypropylene at a weight ratio of 6: 4 .

Therefore, since the lower housing 10 has a large number of microvoids and is flexible, it can absorb sound and sound as well as absorb sound, and can absorb shock and vibration.

The lower housing 10 is provided with a foamed porous polyethylene sheet 20 having a sheet shape.

The porous foamed polyethylene sheet 20 has an upwardly curved round surface 22 when the lower surface thereof is viewed in the longitudinal direction. The porous foamed polyethylene sheet 20 and the lower housing 20 A space S is formed between the bottoms of the first and second substrates 10 and 10.

This space (S) contributes to an increase in heat insulation and a sound insulation, and is most effective for impact and vibration buffering.

In addition, a fitting hole 24 having a diameter equal to the outer diameter of the fastening boss 16 is formed at the center of the porous foamed polyethylene sheet 20.

It is preferable that the upper end of the porous foamed polyethylene sheet 20 is designed to be aligned with the upper end of the fastening boss 16 when the porous foamed polyethylene sheet 20 is fitted to the fastening boss 16 Do.

On the upper surface of the porous expanded polyethylene sheet 20, a glass fiber board 30 is laminated.

The glass fiber board 30 is formed into a plate by pressure molding in a state of being impregnated in a polypropylene resin.

Accordingly, since the glass fibers are randomly entangled with each other to maintain a certain degree of strength, they have an open cell structure and have an elastic repulsive force by pressing, so that they are excellent in vibration and impact absorption, The polypropylene resin is filled, but the unfilled portion forms voids, which eventually improves sound insulation or sound absorption.

A plate hole 32 is formed at the center for fixing the glass fiberboard 30, and a fastening bolt 70 is fitted in the plate hole 32.

In addition, a silicon sheet 40 is laminated on the upper surface of the glass fiberboard 30.

At this time, the silicon sheet 40 is needle-punched (pinhole) so that fine needle holes are formed in several tens to several thousands or more per unit area of 10 cm in height, It is a member that absorbs vibration directly.

That is, since the upper housing 50 is manufactured by molding the same material as that of the lower housing 10, the upper housing 50 is the first sound absorbing material and the dustproof material, .

Therefore, the position of the silicon sheet 40 is required to be the greatest in terms of elasticity as well as the sound absorption function. Therefore, the silicon sheet 40 is needle-punched to form a plurality of fine needle holes Should be formed.

In addition, the thickness of the silicon sheet 40 should be at least thinner than the maximum thickness of the porous foamed polyethylene sheet 20 or the glass fiberboard 30 in the range of 2/3 to 1/3.

This is because it is necessary to maintain the function only because it is intended to increase the adhesion with the upper housing 50 while maintaining the minimum stretchability. Furthermore, it is also the most suitable member to adjust the thickness in order to adjust the thickness of the flooring according to the present invention to the range of 3-5 cm.

A sheet hole 42 is formed in the center of the silicon sheet 40 so that the fastening bolt 70 can be inserted.

On the other hand, the open upper portion of the lower housing 10 is sealed by the upper housing 50.

The upper housing 50 has a shape substantially opposite to that of the lower housing 10 and a lower end peripheral surface is formed with a fitting piece insertion groove 52 into which the fitting piece 12 can be inserted.

In addition, a downwardly convex leaf spring 60 is inserted into the fitting piece insertion groove 52 so as to enable elastic contact when the fitting piece 12 is contacted.

Therefore, when the external force is applied to the fitting piece 12 in a state in which the fitting piece 12 is in contact with the lower vertex of the plate spring 60, the plate spring 60 is elastically buffered while being pressed.

In addition, a fastening bolt hole 54 is formed in the center of the upper surface of the upper housing 50. Particularly, the bolt head of the fastening bolt 70 is completely inserted so that the upper end of the bolt head is inserted into the upper end of the upper housing 50 A bolt head insertion groove 56 is further formed in the upper inner diameter of the fastening bolt hole 54. As shown in FIG.

A coupling groove 58 having a generally inverted trapezoidal shape is formed at the center of each side of the upper end of the upper housing 50 and a coupling hole 80 is formed in the coupling groove 58 So that the adjacent upper housings 50 are assembled by a kind of lego block assembling method.

In other words, the coupling groove 58 corresponds to the half shape of the binding hole 80 and is formed to have an inverted trapezoidal shape with a narrow width in the outer direction of the upper housing 50 and a wider width in the inner direction When the binding member 80 is pressed down, it is easy to separate and disassemble in the up and down direction, but can not be released in the right and left direction orthogonal to the upper and lower direction, so that the binding state can not be released.

At this time, the binding port 80 may be regarded as a ribbon.

The porous foamed polyethylene sheet 20, the glass fiberboard sheet 30 and the silicon sheet 40 are stacked in this order on the lower housing 10, and the upper housing 50 is covered with the stacked sheets, It is possible to complete the buffering type dustproof material for controlling the elastic buffering degree, that is, the flooring for preventing the interlayer noise if the distance between the lower housing 10 and the upper housing 50 is adjusted by bolting with a bolt 70.

In addition, although the porous foamed polyethylene sheet 20, the glass fiberboard sheet 300 and the silicon sheets 40 themselves have excellent dustproof performance and sound insulation performance, the noise shielding effect according to the change in the medium at these interfaces is very large, ) And the fast dispersing effect through the through hole 14 provide a greater sound insulation and dustproof effect than any of the previous dustproof materials and sound insulating materials.

The construction of the bottom material can be easily and quickly assembled by simply pressing the binding hole 80 into the binding groove 58 while the upper housings 50 are disposed adjacent to each other. Therefore, the construction time can be shortened have.

As described above, the apparatus for preventing an interlayer noise according to the present invention has a perfect vibration noise preventing and preventing effect, and it is expected that the application of the apparatus to solve the interlayer noise problem of apartment houses and the like is very large.
