Description

Technical Field

[0001] This utility model relates to the field of cast-in-place beam technology, and more specifically, to a mobile cast-in-place beam side formwork device. Background Technology

[0002] Currently, the steel side formwork used in cast-in-place bridge construction is mostly single-piece assembled formwork. When the construction of the next span is carried out after the completion of one span, the single formwork needs to be disassembled, assembled, and transported. Cranes and transport vehicles need to wait for a long time to coordinate, which consumes a lot of machine shifts and has low efficiency. In particular, when there are municipal roads under the bridge, it will also obstruct the passage of social vehicles, resulting in a long construction cycle for each span of cast-in-place bridge, high safety risks in hoisting operations, and significant impact on traffic.

[0003] A search revealed a utility model patent with publication number CN212801257U, which discloses a mobile cast-in-place beam side formwork device. The surface of the working plate is similar in shape to the side of the cast-in-place beam. The end of the working plate extending upwards from the cast-in-place beam has mating holes at a height higher than the beam surface and facing towards the cast-in-place beam. A support truss is set at the bottom of the working plate to support it, and the bottom of the support truss is equipped with traveling wheels and an adjustable top support. This patent uses the working plate to fit on both sides of the cast-in-place beam and is connected by tie bolts, which helps to ensure the casting quality and facilitates hoisting. The modular unit design is suitable for the construction of cast-in-place beams with various spans, making it highly applicable. The adjustable top support facilitates the adjustment of the formwork height. The roller sliding design, through the cooperation of the traveling wheels and the channel steel track, makes the turnover and transportation of the formwork very convenient.

[0004] The aforementioned patent also has the following shortcomings: adjusting the top support screw on the top support requires manual operation, but the top support is located at a high position, making adjustment inconvenient; in addition, two adjacent side forms also require manual operation to pass bolts through the two outer reinforcing ribs on the back of the working plate to connect the formwork system into one unit, which also makes disassembly and assembly inconvenient. To address these issues, we propose a mobile cast-in-place beam side formwork device. Utility Model Content
