The specific embodiment:
As Figure 1-3, this specific embodiment by the following technical solutions: it comprises case beam steel Bench mould support 1, top locking-bar 2, montant 3, web distribution reinforcement positioning bar 4, bellows positioning steel tube 5 and removable pin 6; The upper lateral of case beam steel Bench mould support 1 is evenly provided with several tops locking-bar 2, the both sides of case beam steel Bench mould support 1 are evenly provided with several montants 3, one side of each montant 3 is evenly provided with several web distribution reinforcement positioning bars 4, the opposite side of montant 3 is provided with several bellows positioning steel tubes 5, the inside of bellows positioning steel tube 5 is plugged with removable pin 6, and bellows 7 is placed on removable pin 6.
This specific embodiment adopts following fixing means:
1, the Bench mould support of steel bar framework of box beam is made and the requirement of Bench mould support montant spacing
According to steel bar framework of box beam size, design, making Bench mould support, Bench mould support montant spacing is 0.8m.
2, bellows single-point three-dimensional position is determined
1) designing unit arranges linear according to prestressing force, linear equations and computational methods are provided, and according to linear equations, (if this case beam is by 0.8m) calculated in selected spacing segmentation, form bellows space coordinates table, design drawing provides bellows space coordinates table.
2) calculating of segmentation three-dimensional position (bellows positioning steel tube position)
The setting-out abscissa x ˊ of bellows positioning steel tube is Bench mould support center line is intended welding position horizontal range to steel pipe.The setting-out abscissa x ˊ of steel pipe equals the design abscissa x of steel strand.
xˊ=x
According to y in design coordinates table, calculate the setting-out ordinate y ˊ at bellows positioning steel tube center.
yˊ=y/(cosα)-（D/2）-（d/2）。
Wherein α---case web inclination angle (°)
D---outside diameter of bel (mm)
D---removable pin external diameter (mm)
3, segmentation three-dimensional position is determined
According to the linear layout of bellows, by accurate calculating, by calculated data (x ˊ, y ˊ) setting-out on Bench mould support montant.
