The utility model relates to a bridge bent cap construction safety protection platform. This safety protection platform makes up into the safety protection platform by preceding, back, left and right four bibliographic categories part unit platform, the safety protection platform pass through the platform lifting rope and install on the punching rod iron, and arrange around the pier stud. The utility model discloses braced system installation (demolising) in -process operation safety in the time of guarantee adopting the rod iron method to pour bridge bent cap (binder) plays the second and says the protective action in the time of simultaneously can be in the overall process of bent cap (binder) construction. Its processing, assemble, demolish etc. Convenient, swift, use safe and reliable, but manifold cycles uses.
Description
Technical field
This utility model belongs to technical field of bridge engineering, is specifically related to a kind of construction safety protection platform when using rod iron method to pour bridge coping (binder).
Background technology
At present, when using rod iron method to pour bridge coping (binder), main employing is set up temporary steel pipe support or directly uses lifting appliance to arrange the cage mounting platform as support system, after secondary beam installation terminates, then laying construction platform and safe protective railing on secondary beam.Temporary steel pipe support is set up in employing need to carry out based process, and the most time-consuming；Directly use lifting appliance that cage is set and the support system bigger security risk of existence is installed.
Summary of the invention
The purpose of this utility model is to provide one and is easy to dismounting, can reuse, can guarantee that the protective platform of safety operation during using rod iron method support system installing (dismounting) when pouring bridge coping (binder), while can in the overall process that bent cap (binder) constructs time play the protective platform of second protective action.
The technical solution of the utility model 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 around pier stud.
The structure of described front, rear, left and right four part unit platforms all includes channel-section steel girder, channel-section steel secondary beam, expanded steel diamond mesh, standing screw, guardrail inserted link, guardrail, skirting board, close mesh safety net, channel-section steel Main Girder Welding becomes a rectangular outer frame, weld multiple channel-section steel secondary beams in rectangular outer frame and form multiple rectangle inside casing, expanded steel diamond mesh is installed in rectangular inner frames, guardrail inserted link and guardrail are installed in the outside of rectangular frame, and guardrail is provided with skirting board and close mesh safety net.
The utility model has the advantages that: during can guarantee that employing rod iron method support system installing (dismounting) when pouring bridge coping (binder), operate safety, while can in the overall process that bent cap (binder) constructs time play second protective action.It processes, assemble, dismounting etc. is convenient, fast, safe and reliable, can be recycled for multiple times.
