A kind of sound-absorbing box body structure is: the hollow rectangle casing being surrounded by top board, base plate and sidewall paneling, box bottom has through hole and leads to box house cavity, lays damping material on base plate
.damping material can be at least one in hollow glass, rock wool, mineral wool or string damping material, can be also prefabricated wood wool acoustical board, ceramic honey comb acoustical board or groove wood acoustical board.The preparation method of sound-absorbing casing, according to the top board of the prefabricated sound-absorbing casing of dimensional requirement, base plate and sidewall paneling; On base plate, place sound-absorbing sheet material or lay damping material, cavity is arranged at the top of sheet material, then top board, base plate and sidewall paneling is bonded to body structure.
Another kind of sound-absorbing box body structure is: the hollow rectangle casing being surrounded by top board, base plate and sidewall paneling, box bottom has through hole and leads to box house cavity, fills damping material in through hole.According to the top board of the prefabricated sound-absorbing casing of dimensional requirement, base plate, sidewall paneling, damping material is filled in bottom hole, then top board, base plate and sidewall paneling is bonded to body structure.
In box bottom, two-way two free ends that are installed with reinforcing bar and reinforcing bar stretch out outside base plate in length and breadth.
Described base plate and top board adopt concrete, cement mortar, magnesia cement or gypsum to make.
The making of prefabricated sound-absorbing box bottom in cast-in-place concrete floor: first place mould fixing on vibroplatform, place overhanging reinforced mesh, mold bottom is metal sheet, fixes some metal columns that are evenly distributed above; Just reinforcing bar is welded in advance reinforced mesh and is placed in mould, and stretch out outside mould by the groove of mould surrounding reinforcing bar outer end; The concrete being stirred is in right amount poured into in-mold molding; Then the demoulding, maintenance processing obtain sound-absorbing box base plate.
Beneficial effect of the present invention is: the integrated sound-absorbing floor of cast-in-situ concrete of the present invention has effectively solved Indoor environment noise pollution problem, do not needed secondary noise reduction finishing, greatly reduce noise reduction cost, duration, and saved the architectural space because of noise-reducing waste.
