Abstract
The invention provides a safety protection platform for bridge cap beam construction. The safety protection platform comprises a front platform unit, a rear platform unit, a left platform unit and a right platform unit. The safety protection platform is mounted on a core-penetrating steel bar through platform hoisting ropes and arranged around a pier column. The safety protection platform has the advantages that the operation safety during the mounting (demounting) process of a support system when a bridge cap beam (tie beam) is poured through a steel bar method can be guaranteed, the safety protection platform can provide secondary protection during the whole construction process of the cap beam (tie beam) at the same time, and the safety protection platform is convenient and fast in machining, assembling, demounting and the like, safe and reliable to use and capable of being repeatedly recycled.
Description
Technical field
The invention belongs to technical field of bridge engineering, be specifically related to a kind of construction safety protection platform while adopting rod iron method to build bridge coping (binder).
Background technology
At present, while adopting rod iron method to build bridge coping (binder), main employing set up temporary steel pipe support or directly adopted lifting appliance that the mounting platform of cage as support system is set, after secondary beam is installed and is finished, then on secondary beam laying construction platform and safe protective railing. Temporary steel pipe support is set up in employing need carry out based process, and more time-consuming; Directly adopt lifting appliance that cage is set the larger security risk of support system existence is installed.
Summary of the invention
The object of this invention is to provide one and be convenient to dismounting, can reuse, when energy ensures to adopt rod iron method to build bridge coping (binder), support system is installed the protective platform of safety operation in (dismounting) process, plays the protective platform of second protective action in the overall process that simultaneously can construct at bent cap (binder) time.
Technical scheme of the present invention is: a kind of bridge coping construction safety protection platform is combined into security protection platform by front, rear, left and right four part unit platforms, described security protection platform is arranged on punching rod iron by platform lifting rope, and is arranged in pier stud around.
The structure of described front, rear, left and right four part unit platforms includes channel-section steel girder, channel-section steel secondary beam, expanded steel diamond mesh, standing screw, protect block inserted link, protect block, skirting board, close order safety net, channel-section steel Main Girder Welding becomes a rectangular outer frame, in rectangular outer frame, the multiple channel-section steel secondary beams of welding form multiple rectangle inside casings, in rectangle inner frame, expanded steel diamond mesh is installed, the outside of rectangular frame is installed to protect to block inserted link and protect and is blocked, and protects to block that skirting board and close order safety net being installed.
Advantage of the present invention is: can ensure to adopt rod iron method to build bridge coping (binder) time, support system is installed handling safety in (dismounting) process, plays second protective action in the overall process that simultaneously can construct at bent cap (binder) time. Its processing, assembling, dismounting etc. are convenient, fast, safe and reliable, can repeatedly recycle.
