Description

Technical Field

[0001] The utility model relates to the technical field of bridge components, in particular to a casting mould for assembled bridge components. Background Art

[0002] Prefabricated assembled bridges, as the name implies, are different from traditional on-site construction methods such as steel bar binding and concrete pouring. For prefabricated bridges, part or all of the components of the bridge's substructure (piers, abutments, cap beams) and superstructure (box beams, plate beams, T-beams) are processed and formed in the prefabricated component factory, and then transported to the construction site for hoisting and splicing into the main body of the bridge. The various components of the bridge are mechanically connected through embedded holes, embedded steel bars, and connecting devices processed during the prefabrication production process. Grouting is performed using grouting sleeves in the components so that concrete fully fills the pores between the components to achieve overall strengthening. Prefabricated components are connected using grouting sleeves and grouting. The design has high requirements for the quality of grouting and grouting construction, and the quality of grouting and grouting is related to the seismic performance of the bridge and the overall safety performance of the bridge. Therefore, the grouting and grouting operations need to be strictly controlled. By controlling the slurry ratio, targeted grouting and grouting construction measures are formulated to ensure the quality of component connection and the overall seismic resistance and safety performance of the bridge.

[0003] A prefabricated bridge component casting mold disclosed in the Chinese utility model patent application disclosure CN215094365U can prevent deformation, improve practicality, and facilitate disassembly when in use, but still has the following defects: First, the mold is connected with a large number of fixing bolts. When the mold needs to be disassembled to take out the internal bridge component, it needs to be manually disassembled and takes a long time, making the disassembly time-consuming and labor-intensive. Second, when the mold is in use, due to the presence of steel bars and steel bar positioning plates inside, gaps are easily formed between the concrete and the steel bars and the steel bar positioning plates, resulting in unstable internal structure of the component and reduced quality.
