Abstract
Description
More particularly, the present invention relates to a floor dustproofing assembly for flooring, which is embedded in the floor to reduce vibrations and noise transmitted to a lower floor in order to prevent or reduce interlayer noise in a multi- will be.
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 .
As another prior art, Korean Patent No. 10-1356556 discloses an " apparatus for preventing an interlayer noise in a multi-house house ", and more specifically, has a plurality of frame portions, a hollow portion formed by the frame portions, A mortar sound insulating frame on which a plurality of fasteners protruded toward the frame are formed, an insulating plate on which the mortar sound insulating frame is seated and the fastener is inserted so as to penetrate, and a support base which is cramped and supported by fasteners penetrating from the lower portion of the heat insulating plate, And at least one vibration damping plate for closing the hollow portion is formed at a position where the stepped portion is separated from the vibration damping plate. In this case, the vibration noise transmitted through the concrete mortar can be absorbed and dispersed.
It is an object of the present invention to provide a vibration damping assembly for a floor of a dwelling house which is simple in structure and easy to manufacture and install, can more effectively mitigate noise and vibration, and can minimize the possibility of plastic deformation And an object of the present invention is to provide an anti-vibration assembly for a floor.
The object of the present invention is to provide a floor structure which is embedded in a floor for preventing or reducing noise in an apartment building and which is elastically deformable and whose width decreases toward the lower side and the lower end surface touches the installation surface, An elastic supporter including a first upper body extended from the first upper body and a second upper body extending upward from the lower body and being symmetrical with respect to the first upper body; And a vibration damping pad which is elastically deformable and has a greater strain than the elastic supporter and includes an insertion groove into which the first upper body and the second upper body are inserted and a lower surface which is separated from the installation surface And a bottom-side dustproof assembly.
The object of the present invention is also achieved by a method of manufacturing a floor structure for a building, the floor structure comprising a lower body embedded in the floor and capable of elastically deforming to prevent or reducing noise in a building, And a second upper body spaced apart from the first upper body and extending above the lower body and symmetrical with the first upper body; And a protrusion which is elastically deformable, has a greater strain than the elastic supporter, is embedded in the elastic supporter, is convex downward at a position corresponding to the lower body, and has a lower end surface contacting the mounting surface, And the bottom surface of the dustproof pad is spaced apart from the mounting surface.
The first and second upper bodies may be elastically deformed with respect to the lower body when a vertical load acts on the upper surfaces of the first upper body and the second upper body, The first upper body and the second upper body may be filled with the vibration damping pad or the upper side may be shielded.
The height of the elastic supporter may be greater than the thickness of the vibration pad, and the height of the insertion groove may be 3/4 to 4/4 of the thickness of the vibration pad.
The lower end surface of the lower body and the upper surface of the first upper body and the upper surface of the second upper body are parallel to the mounting surface respectively and the width of the lower end surface of the lower body is larger than the widths of the first upper body and the second upper body As shown in FIG.
Here, the gap between the first upper body and the second upper body may be greater than the width of each of the first upper body and the second upper body.
In the anti-vibration assembly according to the present invention, the elastic support includes an elastic rubber layer made of elastic rubber; And a reinforcing layer including an iron core or fiber and formed in the elastic rubber layer and perpendicular to the mounting surface.
Wherein the reinforcing layer is formed of the iron core or the fibers crossing each other to connect the lower body portion and the first upper body portion and the second upper body portion to each other.
The reinforcing layer may be formed on the first upper body and the second upper body so that the deformation amount of the upper body is greater than the deformation amount of the lower body when a vertical load acts on the upper surfaces of the first upper body and the second upper body. And only the lower part of the lower body part.
The elastic supports may be provided in a plurality of the elastic supports and may be arranged such that the arrangement direction thereof is orthogonal to other adjacent elastic supports.
According to the present invention, since the elastic supporter is inserted into the insertion groove of the vibration-proof pad and is engaged with the elastic supporter, the elastic supporter and the vibration-proof pad can be easily coupled, It is preferable that the elastic support is composed of the elastic rubber layer and the reinforcing layer so that the elastic support can be continuously applied to the lower body so that noise and vibration generated from the upper side of the assembly are reduced, It is possible to prevent the plastic deformation against the load, thereby providing a floor vibration preventing assembly excellent in durability.
