One arch rib beam, next arch rib beam just is installed in its laterally adjacent empty place, until assembled complete all arch rib beams；
6) finally each arch rib beam is connected using transverse prestress cable wire, completes the construction of arch rib.
Further, in the step 3), truss crossbeam is provided with dismountable height-regulating support, often saves rib-lifting section
Setting height(from bottom) is adjusted by height-regulating support and positioned.
Further, in the step 3), connected between first arch rib beam and adjacent steel construction bow member using horizontal
Cable wire is connect to be fixedly connected.
Further, in the step 5), keep laterally connecting using lateral connection latching between two neighboring arch rib beam
Connect.
Further, in the step 2), each truss crossbeam transversely may be used by some sections crossbeam section (10)
Dismantling connection forms.
Further, in the step 2), each steel construction bow member is detachably connected by some section box beams along longitudinal direction
Connect and form.
Further, using splicing board component connection between box beam described in two adjacent sections.
Further, the splicing board component includes being arranged on the first splice plate on the inside of two adjacent sections box beam, is arranged on
The second splice plate and bolt assembly on the outside of two adjacent sections box beam, first splice plate and the second splice plate are by adjacent two
The side wall for saving box beam clamps, and adjusts the gap between two adjacent sections box beam according to the curvature of corresponding arch rib, finally by bolt
Component is locked.
Further, in the step 3), the erection sequence of each section rib-lifting section of first arch rib beam is by arch springing
Assembly is docked successively to vault.
Further, the arch rib is reinforced concrete structure.
Compared with prior art, the invention has the advantages that：
First, the present invention is applied by the way that arch rib to be divided into the arch rib beam substep of several laid out in parallel according to arch rib span size
Work, the arch rib Shu Chongliang after decomposition is small, and the bearing capacity of required steel construction bow member diminishes, and reduces basic material and equipment is used,
So as to reduce cost expense, construction period is shortened, avoids and potential safety hazard is caused to the ground of surrounding enviroment.
Second, the steel construction bow member of the present invention is detachably connected using splicing board component, so that steel construction bow member can
Recycling, greatlys save operating expenses.
Third, the construction method of the present invention is assembled to all kinds of arch ribs to have generality, and simple and easy, convenient, tool of constructing
There are very strong operability and practicality.
