Sound absorption and vibration reduction floating floor ground structure for theater and construction method thereof

Abstract

The invention discloses a sound absorption and vibration reduction floating floor ground structure for a theater and a construction method thereof. The structure comprises a concrete bottom plate, a floating foundation structure, an equipment concrete vibration reduction foundation and hoop concrete, and the floating foundation structure comprises a first waterproof layer arranged at the top of the concrete bottom plate, a floating vibration isolation cushion layer arranged at the top of the first waterproof layer, a second waterproof layer arranged at the top of the floating vibration isolation cushion layer, and a steel plate layer arranged at the top of the second waterproof layer; and the floating vibration isolation cushion layer is arranged at the top of the first waterproof layer; the the equipment concrete vibration reduction foundation is formed at the top of the steel plate layer in a pouring mode, the hoop concrete is arranged on the peripheries of the floating foundation structure and the equipment concrete vibration reduction foundation, the top of the hoop concrete is flush with the top of the equipment concrete vibration reduction foundation, and the outer boundary of the floating foundation structure is arranged on the outer side of the equipment foundation. The problem of equipment foundation vibration sound transmission is solved, and the design and use effects of the theater can be achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a sound-absorbing and vibration-damping floating floor structure for a theater and a construction method thereof. Background technique [0002] With the continuous development of social economy, people's cultural and spiritual needs are also getting higher and higher. Large-scale public buildings such as theaters, cultural entertainment, etc. have sprung up all over the country. Such buildings are often considered to have a large short-term flow of people when carrying out entertainment and cultural activities. In order to meet their needs for fire protection, smoke exhaust, and ventilation, more large-scale mechanical equipment must be equipped. These mechanical equipment often produce large vibration and noise during operation, which will seriously affect the use effect of theater buildings. [0003] In view of the above problems, in the prior art, sound-absorbin...

AI Technical Summary

Problems solved by technology

First of all, the enclosure structure of this invention is a masonry enclosure structure, which is not directly connected to the ground. Due to the poor seismic performance of brick-concrete, if the equipment vibrates greatly or is large-scale equipment or works for a long time, it is easy to vibrate and crack. There are security risks

Secondly, the elastic isolation layer is glued to the surrounding structure (masonry). Since the double-sided adhesive is difficult to bond with the masonry, it is easy to fall off when pouring concrete

In addition, the waterproofing of this invention is to return to the top of the concrete, and the waterproofing is close to the steel plate, so there will be no margin. When pouring concrete, because the lower part of the steel bar is glass wool, the steel plate may be inclined during pouring, which will put the The waterproof on the other side is cracked, and there is a hidden danger of waterproofing
