Description

Inter-floor noise prevention material with pentawall dustproof structure {INTER-FLOOR NOISE PREVENTION MATERIAL FOR HAVING PENTAWALL VIBRATION PREVENTION STRUCTURE}

The present invention relates to an interlayer noise prevention material having a pentawall vibration-proof structure, and more particularly, to an interlayer noise prevention material having a pentawall vibration-proof structure capable of effectively reducing light impact sound and heavy impact sound.

In general, inter-floor noise refers to noise pollution that occurs mainly in multi-unit houses such as apartments and row houses. Among floor-to-floor noises, floor impact sound is classified into light impact sound (58 dB or less) and heavy impact sound (50 dB or less). The floor impact sound is easily transmitted to adjacent generations. Therefore, there is a constant quarrel over noise between floors between the house above and the house below, and between the houses with the walls in between.

As inter-floor noise becomes a social problem, attempts to reduce inter-floor noise at the construction stage are continuing. Therefore, in the case of a building that has already been completed, a technology for reducing the noise between floors that is already generated is requested.

7 to 12 , the anti-vibration wall 120 of the base plate 100 includes a plurality of anti-vibration pillars 130 and a plurality of anti-vibration beams 140 .

In more detail, the plurality of anti-vibration pillars 130 are disposed at a position corresponding to the support 110 on the lower side of the base plate 100 . The plurality of anti-vibration columns 130 are arranged in a matrix form to correspond to the plurality of supports 110 . A plurality of anti-vibration beams 140 are included to form a Ramen structure and connect between the plurality of anti-vibration columns 130 . Ramen structure means a structure in which columns support the lower part of the beam. At this time, a plurality of vibration-proof beams 140 are radially connected for each vibration-proof pole 130 . Accordingly, the inter-floor noise applied to the anti-vibration column 130 is absorbed and canceled while being radially dispersed in the plurality of anti-vibration beams 140 , and is absorbed and canceled as it is transmitted from the anti-vibration column 130 to the anti-vibration anchor 200 . In addition, the interlayer noise applied to one anti-vibration column 130 is also transmitted to a plurality of adjacent anti-vibration columns 130 through the plurality of anti-vibration beams 140 . Impact noise is also absorbed and offset by a plurality of adjacent anti-vibration pillars 130 and anti-vibration anchors 200 .

In addition, the vibration-proof pillar 130 has a vibration-proof hollow part 135 formed therein, and a plurality of vibration-proof beams 140 are radially connected to the outside of the vibration-proof pillar 130 . The vibration-proof hollow part 135 and the vibration-proof pillar 130 have different media through which the vibration frequency passes, and the vibration-proof pillar 130 and the vibration-proof beam 140 have different structures. Therefore, the impact noise applied to the vibration-proof pillar 130 is absorbed and canceled while being radially dispersed by the plurality of vibration-proof beams 140, and the noise frequency in the vibration-proof hollow part 135 of the vibration-proof pillar 130 can be offset. have.

In addition, the anti-vibration pillar 130 includes an inner center guide 132 and an outer pillar body 134 .

Here, the inner center guide 132 is vertically connected to the upper surface of the base plate 100 . In addition, the inner center guide 132 may be formed in the form of a circular rod, the outer pillar body 134 is coupled to the upper side of the vibration-proof anchor 200, and a vibration-proof hollow part ( 135) can be formed. In addition, the outer pillar body 134 may be formed to be spaced apart by a predetermined radius around the inner center guide 132 . In addition, the vibration-proof hollow part 135 is formed in a circular shape. Therefore, the inter-floor noise transmitted to the anti-vibration pillar 130 is offset while being dispersed through the inner center guide 132 and the outer pillar body 134 , and the vibration protection between the inner center guide 132 and the outer pillar body 134 . It can be offset while resonating in the hollow part 135.

In an embodiment of the present invention, the outer diameter of the outer pillar body 134 is gradually reduced from the upper side to the lower side. Since the outer diameter of the outer column body 134 is reduced toward the lower side, it can sufficiently withstand a load of 200 kg or more on the outer column main body 134 . In addition, since the lateral cross-sectional area of the outer pillar body 134 is decreased toward the lower side, the impact noise of various frequency bands transmitted from the outer pillar body 134 to the lower side can be offset.

In addition, as shown in the figure, the anti-vibration anchor 200 includes an anchor head 210 and an anchor body 220 .

Here, the anchor head 210 has a guide hole 211 into which the inner center guide 132 of the anti-vibration column 130 is inserted and fixed, and the lower part of the anti-vibration hollow part 135 of the outer column body 134 . inserted and joined to The anchor head 210 is formed in an annular shape to be inserted into the lower part of the vibration-proof hollow part 135 . The anchor body 220 has a seating portion 221 in which a step is formed so that the lower end of the anti-vibration column 130 is mounted on the periphery of the anchor head 210 .

The anchor head 210 is inserted into the lower part of the anti-vibration hollow part 135, the inner center guide 132 is inserted into the guide hole 211, and the outer pillar body ( Since the lower end of the 134) is seated, it is possible to prevent the anti-vibration anchor 200 from being separated or separated from the anti-vibration column 130 . In addition, the impact noise applied to the anti-vibration pillar 130 is transmitted to the inner center guide 132 , the anchor head 210 and the anchor body 220 , and is transmitted to the anchor body 220 through the outer pillar body 134 . And, it can be offset as it resonates in the vibration-proof hollow part 135 between the inner center guide 132 and the outer pillar body 134 . That is, when viewed based on the anti-vibration column 130 itself, the impact noise is absorbed and canceled through three anti-vibration paths.

A vibration-proof space 223 is formed inside the anchor body 220 . The impact noise of the anti-vibration pillar 130 is absorbed and canceled while passing through the anchor body 220 , and as it resonates in the vibration-proof space 223 and is canceled out, two anti-vibration paths are additionally formed. Therefore, when the vibration-proof space 223 is formed inside the vibration-proof body, the impact noise of the vibration-proof pillar 130 can be absorbed and canceled through five vibration-proof paths. In addition, since the vibration-proof space 223 is formed in the anchor body 220, when a load is applied to the vibration-proof column 130, the anchor body 220 is slightly elastically deformed to absorb impact noise.

The anti-vibration space 223 of the anchor body 220 is formed in a hemispherical shape with an open lower side. At this time, the anti-vibration space portion 223 is formed in a symmetrical hemispherical shape with respect to the center of the anchor body 220 . Accordingly, the impact noise is uniformly dispersed throughout the circumferential direction of the anchor body 220 and can be offset. In addition, when a load is applied to the anti-vibration column 130, the anchor body 220 is elastically deformed symmetrically in the vertical direction to absorb the impact noise.

The anchor body 220 is formed in a form in which the outer diameter increases toward the lower side. Therefore, the impact noise transmitted to the upper side of the anchor body 220 can be dispersed and offset while spreading obliquely to the lower side.

The anti-vibration beam 140 connecting the anti-vibration column 130 is formed in an arcuate shape to absorb the impact noise of the weight applied through the upper surface of the base plate 100 . In this case, the upper surface of the anti-jin beam 140 forms a flat surface, and the lower surface of the anti-jin beam 140 is formed in an arcuate shape that increases in height from both sides toward the center. Accordingly, when the impact noise applied to the vibration-proof pillar 130 is transmitted to the vibration-proof beam 140 , noise in various frequency bands may be absorbed and canceled by the thickness difference of the vibration-proof beam 140 . In addition, since the thickness of the vibration-proof beam 140 increases from the longitudinal center of the vibration-proof beam 140 toward the vibration-proof pillar 130 , the rigidity of the vibration-proof beam 140 can be further increased.

The anti-vibration pole 130 includes a first anti-vibration pole 130a disposed on the edge of the base plate 100 formed in a rectangular shape, and a second anti-vibration pole 130b disposed on the inside of the base plate 100 . At this time, a portion of the second anti-vibration pole 130b is disposed at a position corresponding to the center between the first anti-vibration poles 130a, and the remainder of the second anti-vibration pole 130b corresponds to the first anti-vibration pole 130a. placed opposite to the position. Ten of the first anti-vibration poles 130a may be installed on the edge of the base plate 100 , and eight second anti-vibration poles 130b may be installed on the inside of the base plate 100 . At this time, when the first anti-vibration column 130a and the second anti-vibration column 130b are connected by a plurality of anti-vibration beams 140 , the first anti-vibration column 130a and the second anti-vibration column 130b are diamond-shaped vertices. are placed in each section. Accordingly, the impact noise applied to the first anti-vibration column 130a and the second anti-vibration column 130b may be radially distributed through the anti-vibration beam 140 .

An odd number of antijinjams 140 having an arcuate shape are connected to the first antivibration pole 130a, and an even number of antijinking beams 140 having an arcuate shape are connected to the second antivibration pole 130b. At this time, three anti-vibration beams 140 are connected to the first anti-vibration pole 130a disposed at the corner of the base plate 100, and 5 to the first anti-vibration pole 130a disposed on the side of the base plate 100 Dog Bangjinbo 140 is connected.

The anti-jamming beam 140 includes a first arc-shaped anti-jinbeam 141 , a second arc-shaped anti-jinbo 142 , and a third arc-shaped anti-jinbo 143 .

The first arch-shaped anti-jamming beam 141 connects the anti-vibration columns 130 adjacent to the rectangular base plate 100 in an oblique direction. The second arch anti-jamming beam 142 connects the anti-vibration columns 130 adjacent in the longitudinal direction with respect to the rectangular base plate 100 . The third arch-shaped anti-jamming beam 143 connects the adjacent anti-vibration columns 130 in the width direction with respect to the rectangular base plate 100 .

At this time, the first anti-vibration pole 130a disposed at the corner of the base plate 100 is connected to the first arc-shaped anti-jam beam 141, the second arc-shaped anti-jamming beam 142 and the third arc-shaped anti-jam beam 143 one by one. . The first anti-vibration column 130a disposed on the side of the base plate 100 has two first arc-shaped anti-jamming beams 141 , two second arc-shaped anti-jamming beams 142 , and one third arc-shaped anti-jamming beam 143 . is connected In addition, the second anti-vibration column 130b is connected to four first arc-shaped anti-jamming beams 141 , two second arc-shaped anti-jamming beams 142 , and two or one third arch anti-jamming beam 143 .

The length (L1) of the first arc-shaped anti-jamming beam 141 disposed in the diagonal direction is the shortest, and the length L2 of the third arc-shaped anti-jamming beam 143 disposed in the width direction is the length L2 of the first arc-shaped prong beam 141. Longer than the length, the length L3 of the second arcuate protruding beam 142 disposed in the longitudinal direction is the longest (see FIG. 10 ). Accordingly, by adjusting the arch curvature according to the lengths of the first arc-shaped anti-jambo 141, the second arc-shaped anti-jinbo 142, and the third arc-shaped anti-jinbo 143, the first arched anti-jinbo 141, the second arched square The rigidity of the advance 142 and the third arcuate anti-progressive beam 143 may be the same.

The first to third arc-shaped anti-jamming beams 143 constituting the arcuate anti-jimbo 140 are formed to have different arch curvatures constituting the lower part of the main body, respectively. At this time, the shorter the length (L1<L2<L3) of the anti-jinbeam 140 is, the smaller the arch curvature of the anti-jinbeam 140 is formed to make the thickness thinner, and the length of the anti-jinbeam 140 (L1<L2<L3) As the length increases, the arch curvature of the anti-jinbeam 140 is increased to form a thicker thickness. For example, the shortest first arcuate quadrilateral 141 arranged in the diagonal direction has an arch curvature of 83.8, and the third arcuate quadrature 143 arranged in the width direction formed as the second longest has an arch curvature of 158.6. Formed by, the second arc-shaped anti-jamming beam 142 disposed in the longitudinal direction, which is formed the longest, has an arch curvature of 210.9, and can be.

At this time, since the first arched anti-jamming beam 141 disposed in the diagonal direction connecting the adjacent anti-vibration columns 130 is formed with the shortest length L1, the arch curvature is formed small, and the Since the length L3 is formed to be longer than the length L2 of the third arched square beam 143 , the arch curvature of the second arched square beam 142 is greater than the curvature of the third arched square beam 143 . At this time, the thickness of the first arc-shaped anti-jamming beam 141 is formed to be the thinnest, and the thickness of the second arc-shaped anti-jamming beam 142 is formed to be thicker than the thickness of the third arc-shaped anti-jamming beam 143 .
