AI Technical Summary
In existing bridge construction, the bolts are prone to loosening when supporting the double-track rail panel formwork, which can cause the formwork to bulge. In addition, holes need to be drilled on the beam surface for support, which increases maintenance costs.
A track-direction locking device is adopted, which forms a triangular structure through a linear support assembly consisting of a first threaded rod and a movable rod and a corner support assembly. This supports the track-direction locking device, avoids drilling holes in the inner beam surface, and improves stability.
This eliminates the need for drilling holes in the beam surface for support, reducing maintenance costs, improving the stability of the formwork, preventing bulging, and simplifying subsequent maintenance work.
