In apartment buildings such as apartments, multi-family houses, etc., concrete slabs (plate-shaped structural members that make up the floor or ceiling of the structure in construction) are installed on the floor and ceiling. Since the vibration is easily transmitted to the lower layer through the interlayer slab, the 'interlayer noise problem' is becoming a serious social problem.

As the problem of interlayer noise generated in the apartment house is getting worse, a regulation on the noise standard between apartment houses has been prepared.

Meanwhile, various attempts have been made to form a new type of floor structure in order to prevent interlayer noise. For example, Korean Patent No. 10-0776676 discloses a " A plurality of unit block bodies of a split type are combined to thereby exhibit the noise and vibration reduction effect using the air layer and the vibration damping rubber and the hot water pipe installed on the floor of the building is fixed smoothly .

2 is a cross-sectional view of the elastic supporter 10 viewed from the front, and Fig. 10 is a sectional view of the elastic supporter 10 as viewed from the side.

1, 2, 4, 5, 6, and 10 illustrate two parts of the lower vibration damping pad 20 that are different from each other Embodiments are also shown.

The floor vibration preventing assembly 1 according to the present invention includes an elastic supporting body 10, a lower vibration damping pad 20 and an upper vibration damping pad 30 buried in the floor to prevent or reduce interlayer noise of a dwelling unit . The floor vibration preventing assembly 1 according to the present invention is basically designed to reduce or prevent the noise and vibration from being transmitted to the lower layer from 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. 7, the foamed concrete 3 and the cement mortar 4 may be stacked on the upper side of the floor dustproofing assembly 1, and a separate boiler pipe may be additionally installed have.

The elastic support 10 is made elastically deformable and comprises a lower body 11, an intermediate body 12, and an upper body 13. The upper body 13 may be divided into a first upper body 13a and a second upper body 13b.

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

In addition, even when the upper body 13 is divided into the first upper body 13a and the second upper body 13b, the lower body 11, the middle body 12, the first upper body 13a, The upper bodies 13b are integrally formed with each other and made of the same material or a combination of the same materials.

The elastic support 10 is preferably made to have the same thickness t as a whole (see FIG. 4), so that the lower body 11, the intermediate body 12 and the upper body 13 are all made to 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 middle body 12 integrally extends from the upper side of the lower body 11 and connects the lower body 11 and the upper body 13. It is preferable that the middle body 12 has a constant width and thickness along the vertical direction.

The upper body 13 extends integrally from the upper side of the middle body 12 and is formed in a generally rectangular block shape. The width of the upper body 13 may be the same as the width of the middle body 12, and the upper end thereof is (substantially) flat and parallel to the mounting surface 2a.

In the vibration damping assembly 1 for a floor according to the present invention, the elastic supporting body 10 is provided with a noise reduction hole 16 penetrating in a horizontal direction in a part of a region where the middle body 12 and the upper body 13 are formed . The noise reduction hole 16 preferably has a constant cross-section along the direction of penetration. The cross-sectional shape of the noise reduction hole 16 may be polygonal, elliptical, or the like, but is preferably circular.

By forming the noise reduction holes 16, the connecting bridges 16a and 16b are provided on the elastic supporting body 10 and the relatively large elastic deformation on the connecting bridges 16a and 16b when a load is applied to the elastic supporting body 10 .

Specifically, in the elastic support 10 according to the present invention, the load P1 is applied to the lower end 11a of the elastic supporter 10 when the load P1 is applied from the upper side to the lower side (see Fig. 2 (a) A bending stress and a shearing force are exerted on the elastic supporter 10 (in particular, the connection bridges 16a and 16b). By the action of the force, the connection bridges 16a, 16b are elastically deformed and vibrated (B) while dispersing the external force to effectively reduce noise and vibration.

The width W 1 of the lower end face 11a of the lower body 11 in the elastic support 10 according to the present invention is preferably narrower than the diameter W 4 of the noise reduction hole 16 .

As a result, the load P1 acting vertically on the upper end surfaces 13c and 13d of the upper body 13 is not directly (linearly) transmitted to the lower end surface 11a of the lower body 11, The vibration and noise generated on the upper side of the support body 10 are also attenuated without being directly transmitted to the lower end face 11a of the lower body 11 and the vibration and noise reduction effect due to the elastic deformation of the elastic support body 10 can be facilitated .

In addition, the minimum diameter (W 4) is connected to the bridge (16a, 16b) each with a width (W 2, W 3, connection bridge (16a, 16b) of the noise reduction hole 16 in the elastic plates 10 of the present invention Width may be equal to or larger than the width of the first electrode.

Accordingly, when vibration and noise are transmitted from the upper side to the lower side of the elastic support 10, the direction of movement of vibration passing through the connecting bridges 16a and 16b and the direction of movement of vibration passing through the lower body 11 are different from each other The upper body 13 can be elastically deformed easily with respect to the lower body 11, and vibration and noise can be effectively reduced.

Since the upper body 13 is integrally connected to the upper portions of the connecting bridges 16a and 16b, the load acting on the center of the upper body 13 elastically deforms the central portion of the upper body 13, , 16b, and the load acting thereon is dispersed, so that noise and vibration can be reduced.

In the floor vibration preventing assembly 1 according to the present invention, the upper body 13 may be divided into a first upper body 13a and a second upper body 13b.

The first upper body 13a extends integrally from the upper side of the middle body 12 and has a square block shape. The upper end surface 13a 'of the first upper body 13a is (substantially) flat and parallel to the mounting surface 2a.

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

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

In the following description, the first upper body 13a and the second upper body 13b 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 first and second upper bodies 13a and 13b. By the action of the force, the first upper body 13a and the second upper body 13b The external force is dispersed while elastically deforming and vibrating (B), effectively reducing noise and vibration (see Fig. 2 (b)).

And the distance between the width (W 1) comprises a first upper body (13a) and a second upper body (13b) of the bottom surface (11a) of the lower body 11 from the elastic support body 10 according to the present invention (W 7 , And when the interval between the first upper body 13a and the second upper body 13b is not constant, the minimum interval may correspond to this).

The load P1 vertically acting on the upper end surfaces 13a 'and 13b' of the first upper body 13a and the second upper body 13b 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 support 10 are also transmitted to the lower end face 11a of the lower body 11 and are attenuated without being transmitted directly (linearly) It is possible to easily obtain the effect of vibration and noise reduction caused by deformation.

In addition, interval of the first upper body (13a) and the spacing between the second upper body (13b) (W 7, a first upper body (13a) and a second upper body (13b) in the elastic support body 10 according to the present invention If this is not certain, that the minimum spacing may be equivalent) has a first upper body (13a) and a second upper body (13b) each with a width (W 5 and W 6, a first (13a upper body) and a And the width of the upper body 13b is not constant, the minimum width may correspond to the width of the upper body 13b).

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

The lower body 11, the intermediate body 12 and the upper body 13 are obtained by dividing the elastic supporting body 10 according to the present invention by the respective positions. When the elastic supporting body 10 according to the present invention is divided into materials The elastic rubber layer 14 and the reinforcing layer 15 can be distinguished.

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 in the form of a belt of fibers (see Figure 5).

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, such a combination structure of the reinforcing layer 15 and the elastic rubber layer 14 ensures that the deformation amount of the elastic supporting body 10 in the vertical direction is reduced while securing the deformation amount of the upper body 13 against the lower body 11 So as to sufficiently reduce the noise and vibration due to the deformation of the connecting bridges 16a and 16b or the first upper body 13a and the second upper body 13b and to reduce the overall plastic strain of the elastic supporter 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.

The reinforcing layer 15 in the elastic support 10 according to the present invention 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 portions of the lower body 11, the middle body 12 and the 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 upper body 11 and the intermediate body 12 and the upper body 13. [

The reinforcing layer 15 may be formed only on the lower part of the upper body 13, the middle body 12 and the lower body 11 when the reinforcing layer 15 is formed on a part of the area of the elastic rubber layer 14. [ For example, the reinforcing layer 15 may be formed only on the lower part of the first upper body 13a and the second upper body 13b, the intermediate body 12 and the lower body 11, and the first upper body 13a And the upper portion of the second upper body 13b may be made of only the elastic rubber layer 14 (see FIG. 6).

The first upper body 13a and the second upper body 13b are connected to the intermediate body 12 while securing the rigidity, particularly the shearing force and the bending rigidity at the portion where the first upper body 13a and the second upper body 13b are connected to the intermediate body 12, The amount of deformation of the upper body 13b can be relatively increased and the amount of deformation of the upper body 13 can be reduced when the vertical load acts on the upper surfaces of the first upper body 13a and the second upper body 13b. It is possible to reduce the amount of deformation of the body 11 and reduce the vibration and noise applied to the elastic support 10 more quickly or reduce the transmission to the concrete slab.

The lower vibration damping pad 20 is formed in the form of a flat plate as a whole, is installed parallel to the mounting surface 2a, and is elastically deformable. For this purpose, the lower vibration damping 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 lower 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 condition, The deformation amount is smaller than the deformation amount per unit length of the lower vibration damping pad 20. [

It is preferable that the lower vibration damping pad 20 is formed to be able to bend while being formed in the form of a flat plate as a whole and the thickness of the lower vibration damping pad 20 is made thinner than the thickness of the upper vibration damping pad 30.

The lower vibration damping pad 20 is provided with a through hole 21 through which the intermediate body 12 of the elastic supporter 10 passes.

The through holes 21 are formed in such a manner that the elastic supporting body 10 is not separated from the left and right direction of the elastic supporting body 10 in a state where the elastic supporting body 10 is coupled to the lower vibration damping pad 20 And the size and shape of the intermediate body 12.

A plurality of through holes 21 are formed on the lower vibration damping pad 20, and the through holes 21 are spaced apart from each other at regular intervals.

When the upper vibration damping pad 30 to be described later in the vibration damping assembly 1 according to the present invention supports the upper body 13 of the elastic supporter 10, (12) and prevents the intermediate body (12) from moving in the lateral direction.
