Fig.

The floor vibration preventing assembly 1 according to the present invention includes an elastic supporting body 10, a supporting bracket 30 and a vibration damping pad 20 which are embedded in the floor to prevent or reduce interlayer noise of the dwelling unit. 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 supporting bracket 30 is preferably made of a material harder (less deformed) than the elastic supporting body 10 and the vibration insulating pad 20, and may be made of PVC, polycarbonate, polypropylene, polyethylene, acrylic, It is preferable to be made of a combination of relatively thin plates.

The support bracket 30 includes a support plate 31, an insertion case 32, and a partition wall 33.

The support plate 31 is formed in a flat plate shape as a whole and is made parallel to the mounting surface 2a. The support plate 31 is provided at the center thereof with an opening hole 31a which is formed so as to pass through in the vertical direction and the opening hole 31a is made to correspond to the shape and size of the end surface of the elastic support body 10

The outer edge of the support plate 31 is in close contact with the lower surface of the vibration-proof pad 20 and supports the vibration-proof pad 20.

The insertion case 32 is in the form of a container opened downward and is coupled to the support plate 31 on the opening hole 31a so that the first insertion groove 34 is formed therein.

The size of the first insertion groove 34 constituting the inside of the insertion case 32 is such that the elastic supporting body 10 can be inserted into the insertion body 32 and the first upper body 12 and the second insertion body 34 of the elastic supporting body 10, So that the upper body 13 is inserted to fit in exactly.

The lower end of the partition wall 33 is engaged with the upper surface of the support plate 31. Particularly, it is preferable that the partition wall 33 surrounds the insertion case 32 so as to be spaced apart from the insertion case 32. Accordingly, an inflow space 35 is formed between the insertion case 32 and the partition wall 33 Respectively.

The bottom wall 33 is opened to the upper side and is installed in the interior of the partition wall 33, that is, in the inflow space 35, when the bottom floor structure of the apartment house is constructed using the floor vibration preventive assembly 1 according to the present invention. A part 3a of the concrete is introduced.

The concrete 3a infiltrated into the inflow space 35 and the concrete 3b around the inflow space 35 are integrally cured and the concrete 3a on the inflow space 35 is elastically deformed from the upper side of the elastic supporter 10 to the elastic supporter 10 This combined structure of the cured concrete 3a, 3b, the support bracket 30 and the elastic support 10 is such that the load applied from the upper side to the lower side of the floor vibration damping assembly 1 is elastic So that it can act on the support body 10 intensively.

In addition, in the floor vibration preventing assembly 1 according to the present invention, by using the support bracket 30 as described above, the coupling between the elastic supporting body 10 and the vibration preventing pad 20 can be firmly and easily performed, The separation of the elastic supporter 10 can be effectively prevented.

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).

A second insertion groove 21 is formed in the lower surface of the vibration-proof pad 20, into which the boundary wall 33 of the support bracket 30 is inserted. The second insertion groove 21 is formed such that the boundary wall 33 of the support bracket 30 is completely inserted so that the upper surface of the support plate 31 can be brought into close contact with the lower surface of the vibration pad 20.

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 is coupled to the elastic supporter 10 and the support bracket 30. [

The second insertion groove 21 is formed in such a manner that the elastic supporting body 10 and the supporting bracket 30 are not separated from each other in the left and right direction in a state where the elastic supporting body 10 and the supporting bracket 30 are coupled to the vibration- So as not to be separated from each other in a state in which no external external force acts).

The supporting bracket 30 is stably fixed and a hollow state is maintained between the first upper body 12 and the second upper body 13 so that a separate foreign matter The concrete to be laid) 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 second insertion groove 21 is formed to penetrate through the vibration pad 20.

However, the height of the boundary wall 33 may be set to be less than the height of the second insertion groove 21.

It is preferable that the elastic supporting bodies 10 and the supporting brackets 30 are coupled to the vibration absorbing pad 20 such that the elastic supporting bodies 10 are perpendicular to the adjacent elastic supporting bodies 10 in the plan view 1), so that stable support can be achieved over the entire area of the dustproof pad 20.

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. This load is transmitted to the inner side of the boundary wall 33 of the support bracket 30 and is transmitted to the elastic supporter 10 even if a load is applied on the region where the elastic supporter 10 and the support bracket 30 are not engaged And the noise and vacuum damping effect through the elastic supporter 10 can be made excellent.

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,
