Description

[0001] The present invention relates to a shock absorbing pad assembly for blocking noise,

More particularly, the present invention relates to a shock absorbing pad assembly for preventing noise from being interposed between a floor and a wall of a building, such as an apartment, So that no noise due to the impact is generated at all, so that the interlayer noise can be prevented very effectively, and the construction can be easily carried out, while the construction of the accelerator pipe for the boiler can be easily carried out without damage during the construction work, So that the heat loss of the pipe can be minimized.

Generally, apartment houses or multi-generational houses have light weight impact sounds such as dropping sounds generated by walls and floors of neighboring households or sounds accompanied by furniture movements due to the special nature of sharing walls and floors with neighboring houses, Noise and heavy impact sound generated when the object is dropped, when the adult is walking in a hurry, is transmitted to the lower layer of the concrete slab, causing severe noise pollution.

In order to solve such a problem of interlayer noise, conventionally, a method of reducing the impact sound by making the slab hard to vibrate by the impact applied to the floor, or by reducing the amplitude of the floor vibration caused by the impact by increasing the slab mass Was adopted.

However, since the slab thickness affects the structure itself and the construction unit price, the minimum standard floor structure according to the structure type is limited by governmental organizations, and therefore there is a limit to decrease the impact noise by increasing the slab mass.

Accordingly, a wet floor method for reducing an impact noise by inserting a buffer layer has been widely adopted. It is based on the principle that the impact energy is not directly transmitted to the structure or absorbed in the process of transferring. It is used on the slab bottom plate as a heat insulation material (pad type, synthetic rubber foam material by waste tire crushing rubber chip + polymeric, polyethylene type Polymer foam material such as E-glass fiber) and a foamed concrete mortar as a filler layer that acoustically disconnects the structure.

In the wet floor method, a heat insulating cushion material is installed to block the interlayer noise while securing insulation on the floor of the slab, a foam layer is formed by placing foam concrete on the heat insulating cushion material, and a bottom floor layer is formed as a heating pipe and finishing mortar .

However, in the case of such a wet flooring method, not only the interlayer noise can be completely removed but also the wet construction must be performed several times, so that the air is long and the workability is poor.

Accordingly, various techniques for preventing interlayer noise have been proposed. For example, Korean Patent Registration No. 10-1128873 (name: floor impact sound isolation structure of a building, hereinafter referred to as " prior art & .

The prior art is a floor impact sound blocking structure in which a supporting layer is provided on a concrete slab of a building and a heat reflecting material, a damping member and a finishing mortar layer are sequentially installed on the supporting layer. In the floor impact sound blocking structure, The support protrusion of the elastic support is inserted in the lower portion of the through hole to support the support layer on the concrete slab and the first space portion is formed by the elastic support between the concrete slab and the support layer And the elastic support is provided with a fitting protrusion protruding from an upper center of the dish-shaped receiving part, an elastic washer is fitted to the fitting protrusion, and an elastic pad is provided at a lower end of the receiving part. A belt-shaped damping member having a thickness and a width is provided, and on the upper portion of the damping member And a second space portion is formed between the heat reflecting layer and the heat reflecting layer, and a wire mesh is provided between the buffer insulating layer and the finish mortar layer '.

However, it is considered that the above-described prior art is effective to some extent to prevent the interlayer noise. However, since the construction is very complicated, the workability of the construction work is very poor, and in the case where a large number of support layers are installed together, The support layers can not be connected to each other, and thus there is a problem that the quality of construction is changed according to the skill level of the operator.
