Vertical column sound absorbing structure for steel structure building

Abstract

The invention discloses a vertical column sound absorbing structure for a steel structure building and belongs to the technical field of steel structure building auxiliary equipment. The vertical column sound absorbing structure is technically characterized in that the vertical column sound absorbing structure comprises a vertical column; the outer wall of the vertical column is sequentially provided with an annular sound absorbing unit, a first sound absorbing ring and a second sound absorbing ring from inside to outside; the annular sound absorbing unit mainly comprises a plurality of inner sound absorbing rings wrapping the outer wall of the vertical column in a stacked mode in the axial direction of the vertical column, outer sound absorbing rings which are in one-to-one correspondence with the inner sound absorbing rings and are arranged at intervals, and sponge ring cover plates arranged at the two ends of the mutually-matched inner sound absorbing rings and outer sound absorbing rings; the corresponding inner sound absorbing rings and outer sound absorbing rings and the sponge ring cover plates at the two ends are matched to form annular sound absorbing cavities which are each filled with a plurality of sound absorbing sponge blocks; and the filling height of the sound absorbing sponge blocks accounts for 75-85% of the total height of the corresponding annular sound absorbing cavity. The vertical column sound absorbing structure for the steel structure building is compact in structure, convenient to mount and good in use effect, and is used for noise reduction of the steel structure building.

Description

technical field [0001] The invention relates to an auxiliary structure of a steel structure building, and more specifically relates to a column sound-absorbing structure for a steel structure building. Background technique [0002] The steel structure workshop mainly refers to the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundations, steel roof trusses and steel roofs, etc. Due to the increase in steel production in our country, many steel structure workshops have begun to be used, which can be divided into light and heavy steel structure workshops. The steel structure workshop has the following advantages: (1) The steel structure building is light in weight, high in strength and large in span. (2) The construction period of the steel structure building is short, which reduces the investment cost accordingly. (3) Steel structure buildings have high fire resistance and strong corrosion resistance. (4) The st...

Problems solved by technology

[0003] At present, steel structure workshops are mainly used for storing items and as large-scale workplaces. During the operation of technicians, especially when using large-scale equipment, the noise is very loud. Not only will it be inconvenient for the personnel in the factory to communicate, but it will also affect The daily life of other residents around the factory may affect the work of other employees, and most importantly, it will also have a negative impact on the human body
