Problems solved by technology

[0003] The main structure of the current sound insulation baffle for building construction is two flat plates wrapped in the middle of the sound-absorbing material, and the fixing method is generally fixed by cement or bolts. However, the sound insulation baffle fixed by cement is difficult to disassemble later, and the cement fixed Sound insulation baffles generally cannot be recycled, which increases the cost of use
The sound insulation baffle fixed by bolts is not strong enough, and it is prone to skew or collapse. The weight of the sound insulation baffle is heavy, which seriously threatens the safety of both sides of the sound insulation baffle

Abstract

The invention provides an assembly type flexible sound absorption and insulation screen. The assembly type flexible sound absorption and insulation screen comprises a plurality of barrier units spliced together, and each barrier unit comprises a framework, a base and a flexible sound absorption and insulation body; and each flexible sound absorption and insulation body is formed by jointly sewing glass fiber protective cloth, a flame-retardant fiber sound absorption material and a flexible damping sound insulation material, each framework is fixed to the corresponding base, a plurality of bolt holes used for being connected with a ground structure are formed in each base, and after the barrier units are assembled, an enclosing wall structure can be defined around a construction site. According to the assembly type flexible sound absorption and insulation screen, the barrier units use combined structures of the frameworks and the flexible sound absorption and insulation bodies, compared with a solid plate structure, the screen is lighter, and even if inclination or collapse occurs, the screen does not harm personal safety; moreover, the connecting structure is easy to mount and can be detached and recycled, so that the use cost is saved; and the assembly type flexible sound absorption and insulation screen can be used indoors and outdoors, and is easy and simple to hang and assemble, the noise control comprehensive cost of the screen is low, the limitation of the appearance and the space is small, and the requirement of a special-shaped sound insulation enclosure structure can be met.

Description

technical field [0001] The invention belongs to the technical field of sound insulation for building construction sites, in particular to an assembled flexible sound-absorbing screen. Background technique [0002] During the construction process, various mechanical equipment will be used for operation, and the mechanical equipment will produce noise when working. If the residents in the city are concentrated in the construction, the sound insulation baffle is one of the facilities that must be prepared before construction. [0003] The main structure of the current sound insulation baffles for building construction is the sound-absorbing material wrapped in the middle by two flat plates. The fixing method is generally fixed by cement or bolts. However, the sound insulation baffles fixed by cement are difficult to disassemble later, and the cement fixed Sound insulation baffles generally cannot be recycled, which increases the cost of use. The sound insulation baffle fixed b...
