(4) splice Pier Formwork, lift the Pier Formwork spliced, be inserted in pier stud reinforcing cage;
(5) in Pier Formwork side, People's Bank of China's cat ladder is installed, at Pier Formwork top fitting operation platform, around described operating platform, is provided with guardrail;
(6) pier stud concrete is built;
(7) remove Pier Formwork, People's Bank of China's cat ladder and operating platform, complete pier stud pouring construction.
In technique scheme, numerical-control bending machine in described step (1), is adopted to carry out the making of stirrup and skeleton muscle.
In technique scheme, in described step (3), adopt total powerstation by the setting-out of pier stud sideline in cushion cap template, and with fine rule pull-out pier stud ground appearance profile, as the reference line that pier stud reinforcing cage is installed.
In technique scheme, in described step (3), the suspension centre of reinforcing bar cage hoisting is positioned at 1/3 long place of reinforcing cage, and mount type steel spreader during lifting, described suspender is symmetrical arranged suspension ring.
In technique scheme, in described step (3), described reinforcing cage and cushion cap are welded and fixed.
A kind of Pier Formwork, for the pier stud construction method of claim 1, comprise first-phase to plate and second-phase to plate, described first-phase is curved design to plate dual-side and second-phase to plate stitching portion, and described first-phase is reinforced by diagonal member plate plate and second-phase.
Further technical scheme, described first-phase is provided with web frame to plate and second-phase to the plate back side.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. pier stud skeleton of the present invention adopts overall batch production making shaping, carry out colligation on ground and become reinforcing cage, have that the bar material proportion of goods damageds are low, processing precision of reinforcing steel bar is high, crudy is convenient to control, manufacturing speed is fast, little and reduce the feature of labour intensity by weather effect.
2. the present invention processes pier stud reinforcing cage, synchronously can carry out, shorten construction period with bearing platform construction, and can according to site operation schedule requirement, have bad luck reinforcing bar when selecting to install to on-the-spot colligation, decrease the open-assembly time of pier stud reinforcing bar in outdoor, ensure that the quality of pier stud reinforcing bar.
3. pier stud reinforcing cage of the present invention is shaping at floor manufacture, and relative to traditional colligation aloft, the appearance and size of pier stud easily controls to put in place, guarantees foot stall steel tendon protective layer thickness qualification rate.
4. the present invention arranges People's Bank of China's cat ladder and operating platform on Pier Formwork, decreases the working procedure that scaffold is torn in traditional taking open, saves scaffold and takes the labour cost of tearing open and material is rented with expense, meanwhile, avoid the construction safety risk of operation on scaffold.
5. Pier Formwork of the present invention is after pier stud has been built, convenient disassembly, can not destroy the globality of pier stud, and first-phase is curved design to plate dual-side and second-phase to plate stitching portion, can effective mortar leakage prevention.
Accompanying drawing explanation

Fig. 2 is Pier Formwork structural representation of the present invention in embodiment one.
Wherein: 1, first-phase is to plate; 2, second-phase is to plate; 3, diagonal member.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: shown in Figure 1, a kind of pier stud construction method, comprises the steps:
(1) in factory, concentrated processing making stirrup and skeleton muscle, as reinforcing bar semiproduct, carry out cushion cap reinforcing bar and model sheetinstallat simultaneously;
(2) reinforcing bar semiproduct are transported to job site, colligation becomes pier stud reinforcing cage;
(3) by pier stud reinforcing bar cage hoisting on cushion cap, and to fix with cushion cap;
(4) splice Pier Formwork, lift the Pier Formwork spliced, be inserted in pier stud reinforcing cage;
