Description

Technical Field [0001] The present invention relates to a rubber-fiber structure used for reducing noise in a building structure, and a method of using the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber-fiber structure used for reducing the interlayer noise of a building and a method of using the same. More particularly, the present invention relates to a rubber- Shock absorbing materials such as fiber mats, rubber mats and porous resin mats (styrofoam) have been used to achieve the interlaminar noise-proof structure. However, the present invention uses a rubber-fiber structure that provides a harmonious planar arrangement of the elastic material and the sound- It is the invention of the technical idea to achieve the structure of the interlayer noise reduction of the building.

In recent years, there has been a lot of civil complaints due to floor noise in the living spaces of apartments and offices, and the fact that the lawsuit is causing problems. The impact sound of general buildings is divided into light impact sound and heavy impact sound. It means that the sound is transmitted to the lower layer due to the impact applied to the floor when falling or moving furniture. It has a high middle / high frequency band and has similar noise characteristics in the whole frequency band. have.

In addition, the term "heavy impact sound" means a sound generated when a child is running or running, such as a sound generated when an adult walks, and has a characteristic of lowering the noise level in a low frequency band toward a high frequency band. Or less.

However, only the above-mentioned regulations are presented, but the present invention is not strictly applied since it does not yet find a satisfactory structure satisfying the above conditions or satisfying the layer noise reduction structure.

A lightweight foamed concrete layer 2 placed on the concrete slab layer 1 for heat insulation to serve as a heat insulating material, a lightweight foamed concrete layer 2 for covering the upper and lower layers of the building, A concrete mortar layer 5 in which a noise reduction material layer 3 installed on the upper side of the layer 2 and a heating pipe 4 for heating the room are embedded and a floor finishing material 6 installed on the finishing mortar layer 5 The construction of the floor of the building is generally applied.

In the concrete slab structure having the above-described structure, even when a floor impact sound generated by a collision with the floor finishing material 6 is reduced by a floor finishing material 6 and a heat insulating material (such as foamable soft material) The floor impact sound, especially the heavy impact sound, which is generated by the collision of the impact with the floor finishing material 6, may cause a secondary noise generated due to the vibration on the ceiling surface of the lower layer, And the upper floor impact sound caused by the vibration of the wall (vibration) invites various complaints because it infringes on the living space of the tenant who lives in the lower floor.

In order to solve the above civil affairs problem, if the thickness of the concrete slab layer is increased in order to minimize the impact sound caused by the vibration generated on the ceiling or wall of the lower floor, the overall height of the building is increased and the construction cost is increased. As the load on the building increases, the problem of safety management of the building is emerging.
