B, template arrange soft rope along bridge to two ends, soft rope length to bridge flange plate two, by soft for template two rope along to bridge flange plate two ends;
C, manage at wet seam scope Ф 12mm suspension rod outer fit Ф 40mmPVC, utilize chevron buckle by Ф 12mm suspension rod and lie across the fastener for connection of wet seam end face with fixed form;
D, colligation are wet seam reinforcing bar, concreting, curing concrete;
E, lay down chevron buckle, change nut, transfer Ф 12mm suspension rod, under nut is stuck in and template makes Ф 12mm suspension rod drop to bridge;
F, on the pier of beam slab two ends, strain soft rope, from PVC hole, gently disclose template, template is come off;
G, the soft rope in two cooperatively interact, and template are delivered to side pier, transfer to bridge floor turnover and use.
The bridge flange plate of the present invention seam that wets is hung mould construction method and can also be further achieved by the following technical measures.
Aforesaid method, wherein said template selects bamboo slab rubber.
Aforesaid method, the wherein said back cord lumps of wood comprise the direction across bridge back cord lumps of wood and along bridge to the back cord lumps of wood.
Aforesaid method, is wherein also included in bottom template and arranges the short lumps of wood to two ends along bridge, and short lumps of wood center is established along bridge to through hole, soft rope from through hole through tying up on the short lumps of wood.
Aforesaid method, the wherein said steel pipe two underlay lumps of wood lying across wet seam end face, steel pipe is 2 one group, in wet seam scope, arrange some groups.
Aforesaid method, numbering is labeled in wherein said soft rope free end end, and the soft rope in same template both sides numbering is consistent, in different templates, soft rope is numbered and do not repeated.
Adopt after technique scheme, the bridge flange plate of the present invention seam that wets is hung mould construction method and is had the following advantages:
1, formwork structure is simple, and mounting or dismounting are convenient, cheap;
2, on bridge floor and pier, complete the operation of wet seam overall process, do not take place under bridge, be beneficial to construction organization, reduce costs;
3, wet seam construction quality is good, reduces engineering cost.
