It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. And should not be construed as limited to the embodiments described herein.

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.

It should be understood that the embodiments according to the concept of the present invention are not limited to the particular mode of disclosure but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

Since the present invention uses the below-described pre-registered patent No. 1566776 directly, all the features of the device configuration described below can be understood as those described in the registered patent No. 1566776. [

However, the present invention further includes a structure for supporting and lifting the fastening bolt from the lower housing among the structures disclosed in the above-mentioned Japanese Patent No. 1566776 and its operation description, and this part is the most important constitutional feature .

Therefore, the device configuration, characteristics and operation relationship described below will be incorporated by reference in the above-mentioned Japanese Patent No. 1566776, and the configuration related to the main features of the present invention will be described in detail at the rear end.

1 to 3, the flooring material for preventing noise between apartment buildings according to the present invention is applied to the upper surface of a floor slab, which is a concrete constituting each indoor floor of the apartment house.

A floor finishing material having a heating function such as a hot water panel is installed on the top 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 mutually connected by having a top-bottom fitting structure which is not a side fitting type but more precisely a fitting type. So that it is possible to perform precise construction.

The flooring for preventing noise between the apartment houses includes a 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.

The open upper surface of the lower housing 10 is provided with a plurality of, preferably four, fitting pieces 12 that 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 with the inside and the outside of the housing 10, So as to be smoothly circulated.

A fastening boss 16 protrudes at a predetermined 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.

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

Since the lower housing 10 has a large number of microvoids and is flexible, it can absorb sound and sound as well as absorption of shock and vibration, and can maintain its morphology because it has a certain strength.

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

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

The space S contributes to an increase in the heat insulating property and the sound insulation, and is most effective for shock and vibration buffering.

At the center of the porous expanded polyethylene sheet 20, a fitting hole 24 having a diameter equal to the outer diameter of the fastening boss 16 is formed.

It is preferable that the upper end of the porous expanded polyethylene sheet 20 is aligned with the upper end of the fastening boss 16 when the porous expanded polyethylene sheet 20 is inserted into the fastening boss 16.

On the upper surface of the porous foamed polyethylene sheet 20, a glass fiberboard 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.

On the upper surface of the glass fiberboard 30, a silicon sheet 40 is laminated.

The silicon sheet 40 is needle punched so that fine needle holes are formed in several tens to several thousands or more per unit area of 10 cm in the vertical and horizontal directions and impact and vibration transmitted from the upper housing 50 It is a member which absorbs directly.

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 vibration absorbing material. Secondly, .

Since the silicone sheet 40 is required to have the greatest elasticity and the sound absorbing function must be maintained, the silicon sheet 40 is needle-punched to form a plurality of fine needle holes Should be formed.

The thickness of the silicon sheet 40 should be thin enough to have at least a thickness in the range of 2/3 to 1/3 of the maximum thickness of the porous foamed polyethylene sheet 20 or the glass fiberboard 30.

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

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

The open upper portion of the lower housing 10 is sealed by the upper housing 50.

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

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.

When the insert piece 12 receives an external force in a state of being in contact with the lower vertex of the leaf spring 60, the leaf spring 60 is compressed and elastically buffered.

A fastening bolt hole 54 is formed at the center of the upper surface of the upper housing 50 such that the bolt head of the fastening bolt 70 is fully inserted so that the upper end of the bolt head is aligned with 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).

A coupling groove 58 having a generally inverted trapezoidal shape is formed at the center of the length of each side of the upper end of the upper housing 50. A coupling hole 80 is formed in the coupling groove 58 Thereby assembling the adjacent upper housings 50 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 an inverted trapezoidal shape having a narrow width in the outer direction of the upper housing 50 and a wider width in the inner direction So that it is easy to separate and disassemble in the vertical direction but can not be released in the left and right direction orthogonal thereto so that the binding state can not be released so as to increase the binding force and to make the workability very easy and quick do.

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, A buffering type dustproof material for controlling the elastic buffering degree, that is, a flooring for preventing the interlaminar noise, when the distance between the lower housing 10 and the upper housing 50 is adjusted by bolting with the tightening bolts 70, It can be completed.

The porous foamed polyethylene sheet 20, the glass fiberboard sheet 300 and the silicone sheet 40 have excellent vibration damping performance and sound insulation performance. However, the sound insulation effect of the porous foamed polyethylene sheet 20, The noise absorbing power in the space S 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 simply by pressing the coupling hole 80 into the coupling groove 58 with the upper housing 50 disposed adjacent to the coupling hole 58. Therefore, Can be shortened.

As described above, the flooring for preventing noise between apartment houses according to the present invention has a perfect vibration noise preventing and preventing effect, and it is expected that the application of the flooring noise to a floor of an apartment house, such as an apartment house, is very large.
