2. bed die template 6 adopts bamboo slab rubber, and should draw the axis of logical line traffic control whole beam when bamboo slab rubber is laid, misalignment of axe controls within 10mm.
3. the reserved cavity of round steel suspending rod 2 position has been laid in bed die template 6, after accurate setting-out, forms with hand-held electric saw cutting.
Five, stiff skeleton is lifted in place to bed die template
1. stiff skeleton is assembled complete after, the stirrup of mounting rail base plate and side plate and the longitudinal reinforcement of base plate on the ground.
2. stiff skeleton in place before, first according to the equal concrete pad of topping thickness setting between stiff skeleton 1 with bed die template 6.
3. stiff skeleton 1 is lifted in bed die template 6 and adopts mobile crane, and mobile crane should be selected according to the actual weight of stiff skeleton, must meet the security requirement of lifting.
4. before stiff skeleton lifting, cable wind rope must be fixed in two ends, to control the direction of stiff skeleton after lifting.
5. time in place, put down wire rope first lentamente, make close to pedestal upper base mould template 6 bottom stiff skeleton, under then making first suspension rod by adjustment loop wheel machine large arm, anchor plate is close with the location lumps of wood, then makes stiff skeleton laterally in place by the personnel on both sides.
6. stiff skeleton in place before, must by good for the concrete pad pad of bottom, concrete pad must symmetrical ground cushion on the same foundation mould lumps of wood.
7. stiff skeleton is completely in place and drop on after in concrete pad, check whether the preformed hole in round steel suspending rod 2 anchor plate and bed die template 6 coincide, and whether stiff skeleton both sides topping meets the demands, and then can unclamp the wire rope of loop wheel machine.
Six, round steel suspending rod, suspended cross-beam are installed
1. suspension system erection sequence: stiff skeleton lower chord hole → install round steel suspending rod → by suspended cross-beam to be put into below round steel suspending rod → with 2 1t leading block of chain, suspended cross-beam is adjusted lateral attitude after to rise between two round steel suspension rods → backing plate is installed and with nut, suspended cross-beam is tightened → unclamp leading block of chain → same method and the suspended cross-beam of other nodes is installed.
2., after stiff skeleton completes, by good for the reserved hole drill of round steel suspending rod on lower chord, pitch-row must be carried out according to constructure scheme arrangement diagram.
3. when suspension system is installed, must ensures that round steel suspending rod is vertical, when tightening up suspended cross-beam with leading block of chain, should adjust simultaneously, after round steel suspending rod is vertical, then suspended cross-beam and round steel suspending rod be tightened.
Seven, safety protection facility is installed
1. the safety protection facility suspending system in midair mainly contains: side shield railing 11, bottom operation platform 10 and upper strata operating platform 12 etc.
