Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction work platforms, in particular to a work platform for lattice beam connection construction. Background Art

[0002] In recent years, my country's highway infrastructure construction has developed rapidly, and the number of cross-river bridges has increased. Lattice beams are common structural beams in cross-river bridges. Lattice beams are generally I-beam crossbeams. During the installation of lattice beams, after the adjacent segments are hoisted in place, the top plates, bottom plates and webs of the adjacent segments of the lattice beams need to be welded or bolted to connect the adjacent segments. Since bridges often cross rivers, the welding or bolting of lattice beams requires high-altitude operations. There are two methods for high-altitude construction of traditional bridges. One is to set up scaffolding for construction, and the other is to rent lifting equipment and use the cage of the lifting equipment on the bridge deck for construction. The former method requires a large amount of construction site, has high requirements for the ground, and has low construction efficiency. The latter requires renting a large number of construction platform equipment, which directly affects the construction cost.

[0003] In order to improve work efficiency and reduce construction costs, steel pipes or steel bars, steel ladders and foot pedals are often used to assemble and build construction platforms. However, the assembled construction platform needs to be disassembled and assembled every time it moves to a connection segment. The disassembly and assembly are cumbersome, and the connections between the components are not tight, and the edge protection is incomplete, which poses a great safety risk. After searching, it was found that there is currently no special platform for lattice beam connection construction. Therefore, in order to improve construction efficiency, reduce construction costs and reduce safety risks, it is necessary to design a special platform for lattice beam connection construction. Summary of the invention

[0004] The utility model aims to provide a working platform for lattice beam connection construction. The working platform for lattice beam connection construction is light in weight and can be easily transferred. Moreover, surrounding protection is arranged on the working platform, so the safety is guaranteed.

[0005] The utility model is realized by the following technical solutions:

[0006] A work platform for lattice beam connection construction comprises a square frame, wherein the square frame is an open square frame at the top, a vertical pole is respectively arranged on both sides of the front end of the square frame, a curved hook extending forward for clamping on the top plate of the lattice beam is correspondingly arranged on the top of each vertical pole, a ladder for facing the bottom plate of the lattice beam is connected to the front end of each vertical pole along the height direction of the vertical pole, and a bottom plate is arranged on the inner bottom of the square frame.

[0007] Further preferably, a connecting rod is fixedly connected between the two vertical poles, and the connecting rod is used to improve the strength of the vertical poles, so that the hooks for hanging the lattice beam top plate are more stable.

[0008] Further preferably, the two vertical poles are respectively connected with a reinforcing rod, one end of the reinforcing rod is connected to the vertical pole, and the other end of the reinforcing rod is connected to the rear end of the bottom of the corresponding side square frame. The reinforcing rod improves the connection strength between the vertical pole and the square frame, and improves safety.

[0009] Further preferably, the upper and lower corners of the ladder frame of the ladder away from the upright side are arranged in an arc shape. The upper and lower corners of the ladder frame are arranged in an arc shape, which can facilitate the overall lifting and lowering of the working platform and avoid the ladder frame and the lattice beam from getting stuck.

[0010] Further preferably, the upper front end of the square frame is lower than the upper rear end, that is, no frame rod is provided at the upper front end of the square frame, so as to facilitate the connection construction operation of the lattice beam.

[0011] Further preferably, the inner lower part of the square frame is provided with a panel around the bottom plate. The bottom plate and the panel are both connected and fixed to the square frame. The bottom plate and the panel can be made of wood. The bottom plate is used for workers to stand and place tools. The panel can prevent the tools or parts placed on the bottom plate from slipping off.

[0012] The main body of the working platform for the lattice beam connection construction can be welded with steel bars to form a ladder cage structure. The bottom plate and the enclosure are connected and fixed to the square frame. The bottom plate and the enclosure can be made of wooden boards, which are light in weight and can be easily transferred. In addition, the working platform is provided with surrounding protection to ensure safety. BRIEF DESCRIPTION OF THE DRAWINGS
