Description

Technical Field

[0001] The utility model relates to a ladder for grid construction and belongs to the technical field of building construction. Background Art

[0002] At present, the grid needs to be assembled and welded on the ground before it is lifted. Construction workers usually use inclined ladders made of steel pipes or lifts to work. It takes a long time and costs a lot to build a ladder with steel pipes. During the construction period, it is necessary to stop work and wait, which affects the construction period and is not convenient to move and change positions. Using a lift is expensive and increases construction costs. If the ladder is spot welded on the grid, the ladder and the grid need to be welded in the early stage, and the ladder and the grid need to be cut in the later stage. In this way, the parent material is easily damaged and deformed, which seriously affects the construction quality and safety.

[0003] Prior art CN218150703U is a ladder for grid construction, which discloses that the grid is fixed to the ground, and the ladder is vertically placed below two groups of web bars forming a herringbone shape, and the screw is rotated to drive the horizontal column to move downward, so that the lower end of the telescopic cylinder is in contact with the ground, thereby lifting the ladder, so that the web bar is located in the U-shaped groove of the U-shaped plate and forms a conflict with the U-shaped plate, at this time, the fastening spring is in a compressed state and the upper end of the blocking column conflicts with the inner cavity top wall of the telescopic cylinder, and the ladder and the web bar can be stably fixed by the fastening spring, and the support beam is threadedly connected to the ladder, and it can be disassembled when not in use to avoid it getting in the way. It is necessary to align the U-shaped groove with the web bar, and at the same time, the screw needs to be rotated to fix the entire ladder, which cannot be operated by one person, and the installation and disassembly process is still relatively cumbersome.

[0004] Therefore, there is an urgent need for a ladder that is easy to assemble and disassemble and convenient to move. Utility Model Content
