By adopting technique scheme, when building this superstructure, be well placed successively by reinforcing bar, then inserted by filler in the clamping part of some reinforcing bars formation, clamping part defines the position of filler naturally, when placing of concrete, although filler lighter weight is still fixed by clamping part and can not float or move, installation process is easy, fixation, simultaneously can not that filler be caused to fix be insecure because of the misoperation of workman, greatly accelerate the progress of engineering.
The utility model is set to further: each filler is at least provided with 3 reinforcing bars.
By adopting technique scheme, the reinforcing bar of more than three or three just can form a stable clamping part, and after filler is put into, the formula that can not be distorted floats or movement.
The utility model is set to further: U-shaped portion opening part size is greater than size bottom U-shaped portion, and filler width size is greater than size bottom U-shaped portion, and filler thickness size is less than the depth size of U-shaped portion.
By adopting technique scheme, filler can compress by the bending place of clamping part, make to leave space placing of concrete between some fillers simultaneously, after filler is placed on clamping part simultaneously, the upper and lower surface of filler all and between reinforcing bar leaves space, concrete can water so far in space, by complete for reinforcing bar parcel, makes whole concrete hollow building roof structure more firm.
The utility model is set to further: filler offers pipe hole.
By adopting technique scheme, be convenient to by pipeline through pipe hole, without the need to effort punching consuming time separately again.
Compared with prior art, the utility model cast-in-place concrete hollow building roof structure fast by filler fixation, more efficiently, can be saved manpower and material, avoids because workman's maloperation causes filler to fix unstable phenomenon.
