Description

Technical Field

[0001] The utility model relates to the technical field of cofferdam steel platforms, in particular to a cofferdam steel platform structure. Background Art

[0002] Cofferdam steel platform is a temporary or permanent structure used in cofferdam projects in water conservancy projects and civil engineering. It is usually used in rivers, reservoirs, coasts and other areas to enclose water or retain soil to protect surrounding land or facilities from water erosion or mudslides.

[0003] The utility model with announcement number CN216108442U discloses a cofferdam steel platform structure, which relates to cofferdam construction, including steel pipe piles, wherein the steel pipe piles include large piles on both sides, small piles are arranged between the large piles on both sides, the tops of the steel pipe piles are fixedly connected to longitudinal steel frames, and the tops of the longitudinal steel frames are laid with cross plates; the large piles and small piles are arranged at intervals to save materials, the longitudinal steel frames connect each row of steel pipe piles to achieve longitudinal reinforcement, the cross plates are laid on the tops of the steel pipe piles for material transportation and pile driver travel, and the pile driver moves along the length direction of the steel pipe piles, which is more convenient and improves construction efficiency.

[0004] When the above technical solution is in use, when the cross plate is set, it is placed vertically. The rotating plate is in a free-hanging state due to the rotation of gravity. At this time, when the cross plate is vertically dropped to the upper half of the rotating plate and contacts the top of the H-shaped steel, the rotating plate is rotated relative to the cross plate by the pressure of the H-shaped steel, so that the anti-skid plate fixedly connected on the other side of the cross plate contacts the side of the H-shaped groove, thereby increasing the contact area. When the cross plate is subjected to a horizontal force, the cross plate and the H-shaped steel are kept relatively fixed through the friction between the cross plate and the top of the H-shaped steel, and the friction between the anti-skid plate and the side of the H-shaped steel. The greater the gravity applied to the cross plate, the tighter the fit between the cross plate and the H-shaped steel, and the friction plate and the H-shaped steel, and the stronger its anti-skid ability. However, when encountering strong winds, wind may blow through from under the cross plate, and the rotating plate and the cross plate are movably connected, so that the strong wind may lift the cross plate upward, causing certain safety hazards, which is not conducive to actual use. Therefore, those skilled in the art provide a cofferdam steel platform structure to solve the problems raised in the above background technology. Utility Model Content
