Embodiment Construction
[0027] In order to better understand the purpose, structure and function of the present invention, a pipe-through-wall sound insulation structure of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] like figure 1 As shown, the pipe wall sound insulation structure of this embodiment includes a wall 1, the wall 1 is provided with a through hole, the pipe 2 passes through the through hole on the wall 1, and the pipe 2 is sleeved with a sleeve 3, An installation frame 4 is embedded in the through hole, and the installation frame 4 is a cylindrical structure with both ends open. In this embodiment, the installation frame 4 is a circular cylindrical structure, which can be selected according to actual needs in practical applications. A pair of fixing parts 5 are symmetrically fixed on the inner wall of the installation frame 4 , and each of the fixing parts 5 is a flat ring structure. The pipeline 2 passes throug...

The invention discloses a pipeline through-wall sound insulation structure which comprises a wall body, a through hole allowing a pipeline to penetrate through is formed in the wall body, a pipe sleeve is arranged outside the pipeline in a sleeving mode, an installation frame is embedded in the through hole, a pair of fixing parts is arranged on the inner wall of the installation frame, each fixing part is of a flat annular structure, and the pipeline sequentially penetrates through the fixing parts. A filling layer is arranged between the fixing parts; the axial outer side ends of the fixing parts are attached to the sealing piece so that openings in the two ends of the space formed by the mounting frame and the pipeline can be blocked. The side face, away from the pipeline, of the sealing piece is an inclined face which makes linear contact with the edge of the inner wall of the installation frame. And each sealing piece is fixedly connected with the fixing part through a fastening assembly. The sound insulation structure is convenient to disassemble, the pressing degree of the sealing piece is changed by screwing and unscrewing the fastening assembly so as to adapt to radial displacement changes of a pipeline, and the overall sealing and sound insulation effect of the sound insulation structure is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of wall sound insulation, and in particular relates to a pipe wall sound insulation structure. Background technique [0002] Noise pollution, air pollution and water pollution are called the three major pollutions in the world. With the development of society and economy, people's requirements for quality of life are increasing day by day, and the problem of noise pollution has also attracted widespread attention from the society. Especially for some production plants, laboratories, equipment rooms and other places that generate high noise, sound insulation facilities are particularly important. [0003] For building maintenance structures, the use of wall materials, door and window components, etc. with excellent sound insulation performance can achieve a relatively good sound insulation effect. For these parts of the sound insulation measures, a large number of technical achievements have been accumulated....
