Description

Punching stick method bent cap supports regulating system construction method
Technical field
The present invention relates to technical field of bridge construction, especially punching stick method bent caps to support regulating system construction method.
Background technique
In recent years, in Yunnan Province's expressway construction intimately carries out, arduous task and it is urgent.Bridge on highway bent cap Substructure main bearing member, cast-in-place construction quality is not only controlled by concrete mix, pours mode, and with use Construction method it is tightly related.Reasonable construction method is only selected, so that template is solid and reliable, piece is tight, interface is suitable Directly, self weight and construction loads could be resisted, guarantees the stability of capping beam template support system;Operator can safely carry out respectively Kind operation, it is ensured that construction quality and safety, while avoiding many common quality defects.Support Method, Hold Hoop method and punching stick method bent cap are applied Work is common construction method, and three kinds of methods respectively have feature: Support Method uniform force, and overall stability is high, but to foundation requirement Higher, rod piece dosage is time-consuming greatly, and material turnover is slower, and overstocking of materials is than more serious when meeting high pier large volume bent cap;Anchor ear Method is suitable for the common Coping Construction of round pier shaft, to ground no requirement (NR), but need to customize anchor ear in advance, and frictionally load-bearing It is risky;Punching stick method is applicable not only to cylinder pier and is also applied for rectangle high pier construction, sound load passes through to ground no requirement (NR) Rod iron is transferred to pier stud, can not only save bulk materials, artificial investment, can also improve construction efficiency.Yunnan Province's high speed is public Road engineering construction more generallys use punching stick method Coping Construction engineering method, in bent cap axis along the radial pre-buried installation rod iron of pier stud Hole, load bearing support uses diameter for 90 ~ 120mm punching rod iron, places jack by horizontal slope and height on punching stick Upper erection I50c I-steel laterally sets up I10 I-steel by 300mm spacing on stringer and does as support system stringer For spreader beam.
Our company tries to explore punching stick method Coping Construction support regulating system, has put into a large amount of man power and material, at Function has developed novel punching stick method Coping Construction support regulating system, and is supported according to axle method Coping Construction and adjust system System has developed its construction method.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides that a kind of construction efficiency is high, versatile punching Stick method bent cap supports regulating system construction method.
