Sound-absorbing suspended ceiling device under grid structure and construction method of device

Abstract

The invention discloses a sound-absorbing suspended ceiling device under a grid structure and a construction method of the device. The sound-absorbing suspended ceiling device comprises a group of sound-absorbing suspended ceiling plate structures, each sound-absorbing suspended ceiling plate structure is arranged corresponding to each rectangular grid at the bottom of the grid structure, and comprises a rectangular frame, a sound-absorbing cotton plate and inhaul cables; horizontal clamping grooves are formed in the inner sides of four frame edges of the rectangular frame in a full-length mode; the sound-absorbing cotton plate is rectangular, and the side edge of the sound-absorbing cotton plate is correspondingly embedded in the horizontal clamping groove; four inhaul cables are correspondingly connected between spherical joints on the sides, corresponding to the rectangular grids, of the rectangular frame in a pulled mode, wherein each inhaul cable comprises a steel wire rope and asleeve provided with a rubber mat; the sleeve sleeves the outer side of the steel wire rope; and one end of each inhaul cable is fixedly connected with a corner of the rectangular frame, and the otherend of each inhaul cable is detachably connected with one spherical joint of the grid structure. The technical problem that due to the fact that conversion transition construction cannot be conductedon a traditional grid structure, a sound-absorbing cotton plate suspended ceiling cannot be installed is solved.

Description

technical field [0001] The invention relates to the field of building engineering construction, in particular to a sound-absorbing ceiling device under a grid structure and a construction method thereof. Background technique [0002] Under normal circumstances, the ceiling of the concrete ceiling sound-absorbing cotton board usually adopts the form of a transfer layer for conversion and transition, and then the sound-absorbing cotton board is connected vertically. For the steel grid roof, because the ceiling cannot be erected with suspenders and clamps, and at the same time, due to reasons such as the inability of the steel grid rods to bear the load, transition construction cannot be carried out, so that the sound-absorbing cotton board ceiling cannot be installed. Contents of the invention [0003] The purpose of the present invention is to provide a sound-absorbing ceiling device under a grid structure and its construction method to solve the technical problem that the ...
