Impact absorption device and application in interlayer noise barrier structure

Abstract

The present invention relates to a shock absorbing device and an application in an interlayer noise barrier structure, and more particularly, to a shock absorbing device equipped with a main body (100) having a hollow interior and formed with an upper cylinder (120) open to the lower side and a lower cylinder (140) whose upper end is embedded in the upper cylinder (120) so as to be formed in a length-extensible manner, an elastic support column (160) is formed inside at least one of the upper cylinder (120) and the lower cylinder (140) in a lateral direction, and a conductive body (180) is provided which transmits an impact applied to the upper cylinder (120) to the elastic support column (160) by being supported by the elastic support column (160), and in a case where the upper cylinder (120) is subjected to an impact, the elastic support column (160) is supported by the conductive body (180). The length of the main body (100) is reduced, and the elastic support body (160) is elastically deformed through the conductor (180) and absorbs impact. And an impact absorbing device for blocking interlayer noise by mounting the impact absorbing device between a concrete foundation (600) and an indoor floor layer (400), and an interlayer noise blocking structure using the impact absorbing device.

Description

technical field [0001] The present invention relates to an impact absorbing device and an interlayer noise blocking structure, in particular to a device capable of absorbing the impact generated on the floor of a building, and by means of which the interlayer noise generated in the building can be absorbed. barrier structure. Background technique [0002] In recent years, the form of buildings is showing a trend towards the concentration of public housing in multi-storey structures such as apartments or villas. In the public housing as described above, floor-to-floor noise is inevitably generated, resulting in important social problems such as conflicts among occupants. Therefore, in order to ensure a quiet living environment, efforts have been made to achieve performance that can block the impact sound of the floor. [0003] Floor pounding sounds include moderate pounding sounds, such as children jumping, and mild pounding sounds, such as chair pulling. Among them, the m...

Problems solved by technology

However, if the concrete slab thickness of the building floor is increased, not only the volume of the floor slab increases, but also the self-weight of the building increases, which further leads to an increase in the size of major structural components such as beams, pillars, and foundations

Therefore, it will inevitably lead to the lifting of the structure of the building and the increase of the engineering cost, which will lead to the problem of economic decline.
