Description

Technical field:

[0001] The utility model belongs to the field of bridge construction, in particular to a pier cap beam construction operation platform. Background technology:

[0002] During the bridge construction process, before constructing the bridge cap beam, it is necessary to build a construction platform around the pier to facilitate workers to install steel bars, support formwork, pour concrete, etc. on the cap beam.

[0003] In the prior art, the full-frame scaffolding method and the clamp bracket method are generally used to build the construction platform, and both methods have their own shortcomings. When the full-frame scaffolding method is used to construct higher piers, there are problems such as high foundation bearing capacity requirements, long scaffolding time, low efficiency and high safety risks. If the construction foundation is on a river channel or soft foundation geological conditions, it will increase the difficulty of construction and extend the construction period. When the clamp bracket method is used, the size of the bracket erected is small and is similar to the plane size of the cap beam, so the bracket cannot accommodate the construction range of the cap beam and can only be directly below the cap beam. In addition, due to the limitation of the guardrail, it is very inconvenient for the steel bar binding of the cap beam and the installation of the facade formwork, and it does not really play the real role of a construction platform. Utility model content:

[0004] The purpose of the utility model is to provide a bridge pier cap beam construction work platform, and overcome the deficiencies of the above-mentioned prior art, which effectively solves the existing problems in the construction process of the work platform.

[0006] Furthermore, the protection component includes a guardrail enclosure, and a plurality of guardrail enclosures are vertically arranged on the four sides of the top wall of the frame-shaped work board, and a vertical pole is vertically arranged between two adjacent guardrail enclosures, and the bottom end of the vertical pole is fixedly connected to the top wall of the frame-shaped work board, and a connecting strip is horizontally installed on the vertical pole, and both ends of the connecting strip are fixedly connected to the adjacent guardrail enclosures.

[0007] Furthermore, the connecting strips are horizontally installed at both upper and lower ends of the vertical pole.

[0008] Furthermore, connecting plates are installed on both side walls of the guardrail enclosure, and the connecting plates are fixedly connected to both ends of the connecting strip by first bolts.

[0009] Furthermore, the bottom end of the vertical rod is fixedly connected to the top wall of the frame-shaped working board by a second bolt.

[0010] Furthermore, reinforcing ribs are installed on the protective net of the guardrail enclosure.

[0011] Furthermore, the frame-shaped working plate is a patterned plate.

[0012] Furthermore, the main beam, the distribution main beam and the distribution secondary beam are all I-beams.

When building the cap beam 12 at the top of the pier 1, first install the distribution main beam 3 vertically across the tops of the two rows of Y-shaped support frames 2, so that the two rows of Y-shaped support frames 2 can be subjected to force at the same time. The main beam 4 installed across both ends of the top wall of the distribution main beam 3 can reinforce the installation stability of the frame-shaped work board 6. Several distribution sub-beams 5 can evenly distribute the bearing capacity of the frame-shaped work board 6 to the two main beams 4 below. Several guardrail enclosures 7 vertically arranged on the four sides of the top wall of the frame-shaped work board 6 surround the construction work platform to form a safe working area to prevent high-altitude workers from accidentally falling.
