Utility model content
The purpose of this utility model is to provide a kind of cast-in-situ concrete sound-absorbing floor, sound-absorbing casing.
The technical solution of the utility model is achieved in that cast-in-situ concrete sound-absorbing floor, and prefabricated sound-absorbing box body space arrangement, tie up girt strip reinforcing bar between sound-absorbing casing, tie up surfacing steel bar net above sound-absorbing casing, then concreting forms sound-absorbing floor.
A kind of sound-absorbing box body structure is: the hollow rectangular box surrounded by top board, base plate and sidewall paneling, box bottom has through hole and leads to box house cavity, on base plate, lay damping material
.damping material can be at least one in hollow glass, rock wool, mineral wool or string damping material, also can be 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; Base plate is placed sound-absorbing sheet material or lays 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 rectangular box surrounded by top board, base plate and sidewall paneling, and box bottom has through hole and leads to box house cavity, fills damping material in through hole.According to top board, base plate, the sidewall paneling of the prefabricated sound-absorbing casing of dimensional requirement, damping material is filled in bottom hole, then top board, base plate and sidewall paneling is bonded to body structure.
Two-wayly in length and breadth in box bottom be installed with reinforcing bar and two of reinforcing bar free ends stretch out outside base plate.
Described base plate and top board adopt concrete, cement mortar, magnesia cement or gypsum to make.
The beneficial effects of the utility model are: the integrated sound-absorbing floor of cast-in-situ concrete of the present utility model efficiently solves Indoor environment noise pollution problem, do not need secondary noise reduction to fit up, greatly reduce noise reduction cost, duration, and save the architectural space because of noise-reducing waste.

Detailed description of the invention
Below in conjunction with specific embodiment, explanation is further explained to the utility model.
Embodiment 1
Fig. 1 is the sectional view of sound-absorbing floor, and prefabricated sound-absorbing casing 1 gap arrangement, ties up girt strip reinforcing bar 3 between sound-absorbing casing 1, ties up surfacing steel bar net 2 above sound-absorbing casing, and then concreting forms sound-absorbing floor.Wherein, the structure of sound-absorbing casing as shown in Figure 2.The hollow rectangular box surrounded by top board 5, base plate 7 and sidewall paneling 6, box bottom 7 has through hole 8 and leads to box house cavity, and the damping material 9 on box bottom is prefabricated hollow glass sound-absorbing sheet material
.horizontal and vertically in base plate 7 be installed with baseplate reinforcing bar 10 and two of reinforcing bar free ends stretch out base plate 7.
The preparation method of prefabricated sound-absorbing casing in pouring concrete floor, according to the top board of the prefabricated sound-absorbing casing of dimensional requirement, base plate and sidewall paneling; Base plate is placed sound-absorbing sheet material, and cavity is arranged at the top of sheet material, then top board, base plate and sidewall paneling is bonded to body structure.
1) making of base plate, first place baseplate molding mould (Fig. 4) on a vibration table and fix, mold bottom is metal sheet, fixes some metal columns 12 be evenly distributed above, the height of post and the consistency of thickness of mould surrounding frame; Baseplate reinforcing bar 10 is welded into reinforced mesh to be in advance placed in mould, and baseplate reinforcing bar 10 outer end is stretched out outside mould by the draw-in groove 11 of mould surrounding; The concrete be stirred in right amount is poured into in-mold molding, starting shock working platform in forming process, make the concrete in mould shake flat, bubble discharge; Then the demoulding, maintenance process.Knockout course places supporting plate on the concrete shaken, and with locking pliers, supporting plate and mould are fixed (size of supporting plate is greater than the size of mould), and 180 degree of turnover moulds, unclamp the locking pliers demoulding.
