The floor vibration proofing assembly 1 according to the present invention comprises a resilient support 10 and a vibration proof pad 20 buried in the floor to prevent or reduce interlayer noise of a house. The floor vibration preventing assembly 1 according to the present invention is basically designed to reduce or prevent noise and vibration from being transmitted to the lower layer of the upper layer. Therefore, the vertical vibration will be described with reference to the form shown in FIG.

The installation surface described in the present invention means a surface on which the floor vibration damping assembly 1 is placed during construction and when the floor vibration damping assembly 1 according to the present invention is mounted on the upper side of the concrete slab 2 , And the mounting surface corresponds to the upper surface of the concrete slab.

As shown in FIG. 6, the foamed concrete 3 and the cement mortar 4 may be laminated on the floor vibrationproofing assembly 1, and a separate boiler pipe may be additionally installed. have.

The elastic supporter 10 is elastically deformable and comprises a lower body 11, a first upper body 12 and a second upper body 13.

The lower body 11, the first upper body 12, and the second upper body 13 are integrally formed with each other and may be made of the same material or a combination of the same materials.

It is preferable that the elastic supporter 10 is formed to have the same overall thickness so that the lower body 11, the first upper body 12 and the second upper body 13 all have the same thickness.

The width of the lower body 11 decreases toward the lower side and the lower end face 11a thereof is (substantially) flat and contacts the mounting face 2a. Specifically, the lower body 11 has a trapezoidal shape whose width decreases toward the lower side and is formed in a bilaterally symmetrical shape.

The first upper body 12 extends integrally from the upper side of the lower body 11 and has a rectangular block shape. The upper end surface 12a of the first upper body 12 is (substantially) flat and parallel to the mounting surface 2a.

The second upper body 13 is separated from the first upper body 12 and extends integrally from the upper side of the lower body 11 and is formed in a rectangular block shape. The upper surface 13a of the second upper body 13 is (substantially) flat and is also parallel to the mounting surface 2a. The second upper body 13 is preferably symmetrical with the first upper body 12 and is symmetrical with respect to the center of the lower body 11.

The first upper body 12 and the second upper body 13 can be formed in a shape other than a rectangular block, and this shape is shown in Fig. The first upper body 12 and the second upper body 13 may be formed such that the space therebetween is triangular, circular or the like so that the shape of vibration and noise attenuated through the elastic support 10 It goes without saying that it is somewhat different.

In the following description, the first upper body 12 and the second upper body 13 are formed in a rectangular block shape.

When the load P1 is applied from the upper side to the lower side of the elastic supporter 10 according to the present invention, the reaction force P2 corresponding to the load P1 acts on the lower end 11a of the elastic supporter 10 And the bending stress and the shearing force are applied to the elastic supporter 10 (in particular, the first upper body 12 and the second upper body 13). By this action, the first upper body 12, And the second upper body 13 are elastically deformed and vibrated (B), thereby dispersing the external force and effectively reducing noise and vibration.

The width W1 of the lower end surface 11a of the lower body 11 in the elastic supporter 10 according to the present invention is set to be smaller than the width W4 between the first upper body 12 and the second upper body 13 It is preferable that the distance between the upper body 12 and the second upper body 13 is narrower than the distance between the upper body 12 and the second upper body 13.

The load P1 vertically acting on the upper end surfaces 12a and 13a of the first upper body 12 and the second upper body 13 is directly applied to the lower end surface 11a of the lower body 11 The vibration and noise generated from the upper side of the elastic supporting body 10 are also attenuated without being directly transmitted to the lower end face 11a of the lower body 11 and the elastic deformation of the elastic supporting body 10 The effect of vibration and noise reduction can be easily obtained.

The distance W4 between the first upper body 12 and the second upper body 13 in the elastic supporter 10 according to the present invention and the distance W4 between the first upper body 12 and the second upper body 13 The widths W2 and W3 of each of the first upper body 12 and the second upper body 13, the widths of the first upper body 12 and the second upper body 13, It is preferable that the minimum width is equal to or larger than the minimum width, when the widths of the first and second electrodes 13 are not constant.

In this way, vibration and noise are transmitted from the upper side to the lower side of the elastic supporter 10, and the vibration and noise transmitted through the lower body 11 and the moving direction of the vibration passing through the first upper body 12 and the second upper body 13 The first upper body 12 and the second upper body 13 can be elastically deformed with ease relative to the lower body 11, So that vibration and noise can be effectively reduced.

The elastic body 10 according to the present invention is divided into the lower body 11, the first upper body 12 and the second upper body 13 according to the present invention. The elastic rubber layer 14 and the reinforcing layer 15 can be divided into materials.

The elastic rubber layer 14 of the elastic support 10 is made of elastic rubber (elastomer). Specifically, the elastic rubber layer 14 may be made of natural rubber, but is preferably composed of synthetic rubbers such as styrene butadiene rubber, cis-polybutadiene, trans polybutadiene, butyl rubber, styrene isoprene butadiene rubber, Antioxidants, zinc oxide, accelerators, antioxidants, processing and softening oils, binders, and the like.

The reinforcing layer 15 is provided inside the elastic rubber layer 14 and comprises an iron core or fiber. The reinforcing layer 15 may be formed by crossing or woven a plurality of fiber strands and may be formed of natural fibers such as cotton, wool, silk and hemp or synthetic fibers such as rayon, acetate, triacetate, nylon, polyester, And may be formed in the form of a belt of fibers.

The reinforcing layer 15 may be made of steel or steel alloy, or may include carbon fiber, and the plurality of wires may be helically wound around each other.

For example, the formation of the elastic rubber layer 14 may be performed by an extrusion molding machine, and the elastic rubber layer 14 may be formed by an extrusion molding machine. For example, the elastic rubber layer 14 and the reinforcing layer 15 may be formed by various known means. And the reinforcing layer 15 can be made by a pressing roller.

The surface formed by the reinforcing layer 15 is preferably perpendicular to the mounting surface 2a. That is, the longitudinal direction of the iron core and / or the fibers constituting the reinforcing layer 15 is formed along a plane perpendicular to the mounting surface 2a. Accordingly, the load in the vertical direction acting on the elastic support 10 acts along the surface direction of the reinforcing layer 15, and a considerable portion of the load acts on the reinforcing layer 15 along the longitudinal direction of the iron core and / The deformation amount of the elastic supporting body 10 can be prevented from increasing excessively and the overall rigidity of the elastic supporting body 10 can be increased.

Particularly, the combined structure of the reinforcing layer 15 and the elastic rubber layer 14 is advantageous in that the elastic supporter 15 and the elastic rubber layer 14 are combined with each other while securing the amount of deformation of the first upper body 12 and the second upper body 13, 10 in the vertical direction can be reduced so that the reduction of noise and vibration due to the deformation of the first upper body 12 and the second upper body 13 can be sufficiently achieved and the overall plastic strain of the elastic support 10 .

The elastic rubber layer 14 combined with the reinforcing layer 15 made of iron core and / or fiber has a lower deformation rate than the elastic rubber layer 14 itself. That is, The unit length deformation amount of the elastic rubber layer 14 to which the reinforcing layer 15 is bonded becomes smaller than the deformation amount per unit length of the elastic rubber layer 14 and the fatigue strength and elastic limit (elastic limit) increases.

As a result, it is possible to prevent sagging, deformation, and the like caused by plastic deformation even when a repeated load is applied to the floor vibration-damping assembly 1 comprising the elastic support 10 according to the present invention, The dustproof assembly 1 can be provided.

In the elastic support 10 according to the present invention, the reinforcing layer 15 may be formed in the entire area of the elastic rubber layer 14, or may be formed in a certain area.

When the reinforcing layer 15 is formed on the entire surface of the elastic rubber layer 14, the lower body 11 and the first upper body 12 and the second upper body 13 are connected to each other by the reinforcing layer 15 It is possible to increase the rigidity at the connection portion between the lower body 11 and the first upper body 12 and the second upper body 13. [

When the reinforcing layer 15 is formed on a partial area of the elastic rubber layer 14, the reinforcing layer 15 is formed only on the lower part of the first upper body 12 and the lower part of the lower body 11 And the upper portion of the first upper body 12 and the upper portion of the second upper body 13 may be made of only the elastic rubber layer 14 (see FIG. 5).

The first upper body 12 and the second upper body 13 are connected to the lower body 11 while securing the rigidity, particularly the shearing force and the bending rigidity at the portions where the first upper body 12 and the second upper body 13 are connected to the lower body 11, The elastic deformation amount of the upper body 13 can be relatively increased and the amount of deformation of the upper body 12 and 13 when the vertical load acts on the upper end surfaces of the first upper body 12 and the second upper body 13 The amount of deformation of the lower body 11 is greater than the amount of deformation of the lower body 11, and the vibration and noise applied on the elastic support 10 are more quickly eliminated or reduced, thereby reducing the transmission to the concrete slab.

The vibration damping pad 20 is formed in a flat plate shape as a whole, is installed in parallel with the mounting surface 2a, and is elastically deformable. For this purpose, the vibration proof pad 20 may be formed in the form of a conventional EVA (ethylene-vinyl acetate copolymer) foam pad, a polyurethane foam pad, a foamed rubber pad, and the like. .

The vibration damping pad 20 of the floor vibration damping assembly 1 according to the present invention has a greater strain than that of the elastic supporting body 10. That is, when the external force acts under the same conditions, Is smaller than the deformation amount per unit length of the vibration pad (20).

The lower surface of the vibration pad 20 may be provided with insertion grooves 21 and 22 into which the first upper body 12 and the second upper body 13 of the elastic supporter 10 are inserted. The insertion grooves 21 and 22 may be formed in a groove shape (see FIG. 1 (a)) that accommodates the entire first upper body 12 and the second upper body 13, (See FIG. 1 (b)) accommodating the second upper body 13 and the second upper body 13, respectively.

In the former case, a hollow space is formed between the first upper body 12 and the second upper body 13 in a state where the vibration pad 20 and the elastic supporter 10 are coupled. In the latter case, A part of the dust-proof pad 20 is filled between the body 12 and the second upper body 13.

The insertion grooves 21 and 22 are formed in such a manner that the elastic supporting body 10 is not separated from the elastic supporting body 10 in the left and right direction in a state where the elastic supporting body 10 is coupled to the vibration- ), The first upper body 12 and the second upper body 13.

As a result, the gap between the first upper body 12 and the second upper body 13 is filled with the dust-proof pad 20 or the hollow state thereof is maintained, so that a foreign matter (for example, Is not introduced between the first upper body 12 and the second upper body 13 and the elastic deformation of the first upper body 12 and the second upper body 13 can be effectively performed.

The height (depth, h2-h3) of the insertion grooves 21 and 22 is 3/4 to 4/4 of the thickness of the vibration pad 20 (width between the upper surface and the lower surface, h2) (21, 22) may be formed over the entire thickness of the anti-vibration pad (20), or may be formed on a part thereof. In the former case, the insertion grooves 21 and 22 are formed to penetrate through the vibration pad 20. In the latter case, the insertion grooves 21 and 22 are formed in a groove shape at the bottom surface of the vibration pad 20.

When the elastic support 10 is inserted into the insertion grooves 21 and 22 of the vibration damping pad 20 and joined to each other, the elastic support 10 is arranged such that the arrangement direction thereof is perpendicular to the adjacent elastic support 10 (Refer to FIG. 1), whereby stable support can be achieved over the entire area of the vibration-proof pad 20.

The vibration damping assembly 1 according to the present invention includes insertion grooves 21 and 22 into which the first upper body 12 and the second upper body 13 of the elastic supporter 10 are inserted into the vibration damping pad 20, The elastic supporting body 10 may be coupled to the vibration damping pad 20 so that the elastic supporting body 10 is embedded in the vibration damping pad 20 (see FIG. 8).

At this time, the dust-proof pad 20 is provided with a protrusion 26 which is convex downward at a position corresponding to the lower body 11 and whose lower end surface contacts the mounting surface 2a, Are spaced apart from the mounting surface 2a.

The lower end face 11a of the lower body 11 can coincide with the lower end face of the protrusion 26 or the lower end face 11a of the lower body 11 can be completely covered by the protrusion 26, As shown in FIG.

As described above, it is needless to say that the space between the first upper body 12 and the second upper body 13 can be filled with the dust-proof pad 20 or the hollow state can be maintained.

In describing the vibration pad 20 according to the present invention, the 'thickness of the vibration pad 20' means the thickness of the vibration pad 20 excluding the protrusion 26.

In the floor vibration preventing assembly 1 according to the present invention, it is preferable that the vibration proof pad 20 has a greater strain than the elastic supporting body 10. The elastic deformation of the elastic supporter 10 and particularly the elastic deformation of the first upper body 12 and the second upper body 13 can be achieved even when the elastic supporter 10 is coupled to the vibration- Therefore, the noise and vacuum damping effect can be improved.

The bottom vibration damping assembly 1 according to the present invention may be used in combination with a plurality of the vibration damping pads 20 so as to form the same plane at the time of construction. In order to facilitate coupling between the vibration damping pads 20, It is preferable that the end portions 23,

The total height h1 of the elastic support 10 in the floor vibration proof assembly 1 according to the present invention is larger than the thickness h2 of the vibration pad 20.

The elastic support 10 may be coupled to the vibration pad 20 so as to have the same upper end as the vibration pad 20 according to the height of the insertion grooves 21 and 22, (20).

As described above, according to the floor vibration preventing assembly 1 of the present invention, since the elastic supporting body 10 is inserted into the insertion grooves 21, 22 of the vibration absorbing pad 20 and is engaged with the elastic supporting body 10, The pad 20 can be easily engaged and the elastic support 10 can be coupled to the vibration pad 20 having a relatively large strain to suppress noise and vibration generated on the upper side of the floor vibration- The elastic support body 10 is first lowered on the upper body of the elastic support body 10 and then transmitted to the lower body 11 to provide excellent noise and vibration reduction effects and the elastic support body 10 is formed of the elastic rubber layer 14 and the reinforcement layer 15 So that plastic deformation against a continuous load can be prevented, and it is possible to provide a floor vibration preventing assembly (1) excellent in durability.
