Description
Technical field
The present invention relates to Construction Technology field, be specifically related to work in a kind of bridge pier rapid constructionMake platform and construction method.
Background technology
High-speed railway bridge engineering accounts for sizable proportion, and the structure of bridge pier adopts round end type bridge morePier, bridge pier height is from several meters to tens meters, even more than 20 meter. Simple supported box beam bridge pier adopts twoLine round ended pier, is made up of pinner, top cap and pier shaft, bridge pier height from 6m～20m not etc.,Vertical main muscle is Φ 16 screw-thread steels, and stirrup is φ 10 round steel, the horizontal lacing wire φ 10 of pier shaft, top capConfiguring multi-layer reinforced mesh. Such bridge pier structure is relatively simple, and when construction, repetitive operation is many,Often can not cause most personnel's great attention. Construction method of the prior art is first to set upSteel pipe scaffold in the outer or bridge pier of bridge pier, utilizes scaffold to carry out reinforcing bar binding and template is installed.
There is larger defect in said method. There is larger danger in the process of scaffold building,And scaffold building quality the check on danger that the existence of bad scaffold itself is caved in, greatly impactOperating personnel's personal safety. The working space that scaffold can provide is narrow, reinforcing bar binding effectRate is low, and the time is long. The main muscle diameter of bridge pier is little, and framework of steel reinforcement rigidity is little, and easily distortion, needsIncrease a lot of bearing rods, adopt the method for scaffold construction greatly to affect workmen's normal workIndustry, reduces efficiency of construction and construction quality. After reinforcing bar binding completes, due to the impact of scaffold,The narrow space of installation form, affects the normal operation that template is installed, and causes template installation effectivenessLow, the time is long. And the template of easily slinging in work progress collision scaffold, causes pinThe danger that hand frame caves in.
