Description

Technical Field

[0001] The utility model relates to a load-bearing beam installation mechanism used for bridge construction. Background Art

[0002] During the construction and installation of bridge supports, the columns are usually installed first, and then the unloading blocks are placed on the column caps, followed by the load-bearing beams on the unloading blocks, and finally the Bailey trusses are placed on the load-bearing beams. When placing the load-bearing beams on the unloading blocks on the column caps, the load-bearing beams and the column caps must be temporarily fixed. Otherwise, when the Bailey trusses are hoisted, the swing of the hoisting wire rope may hit the load-bearing beams above the column caps, and the crane hook may also hook the load-bearing beams. These uncertain factors can easily cause the load-bearing beams to tip over and fall, resulting in serious casualties. It is urgent to design a safe, efficient, and highly applicable temporary fixing device for the load-bearing beams. Utility Model Content

[0009] Wherein, the supporting block is a unloading block.

[0010] The lower transverse portion is connected to the extended steel pipe pile plate through a fastener.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By clamping the lower flange of the load-bearing beam with a connecting device, the load-bearing beam is fixed, the space above the load-bearing beam is released, and the interference between the temporary fixing device and the Bailey truss is fully avoided, which reduces the construction difficulty, improves the construction efficiency, and ensures the construction safety.
