Description

Technical Field

[0001] This utility model relates to the field of steel cage technology, and in particular to a steel cage hoisting support mechanism for pile foundations. Background Technology

[0002] Pile foundations are an important component of building structures. Pile foundation construction involves first drilling holes in the ground, then cleaning the holes, installing the reinforcing cage inside, and finally pouring concrete to complete the pile foundation construction. During reinforcing cage installation, the crane's lifting wire rope is directly connected to the circumferential reinforcement at the top of the cage, lifting it to a position directly above the pile hole. The cage is then lowered into the pile hole, completing its installation. To prevent deformation during lifting, a cross-bracing reinforcement is installed every 4 meters before the cage leaves the factory. During installation, all cross bracing reinforcements must be removed from bottom to top without omission.

[0003] A search revealed that patent number "CN217758788U" discloses "a pile foundation rebar cage hoisting device. The support frame is placed on the ground, with the lifting drive positioned directly above the pile hole. Then, the sliding drive is activated, causing two clamping rods to move simultaneously away from the center of the lifting drive, making the distance between the two clamping rods greater than the width of the rebar cage. The sliding drive is stopped, and then the lifting drive is activated again, moving the support frame closer to the ground, causing the clamping rods to move closer to the rebar cage. When the two clamping rods are on the side wall of the rebar cage, the sliding drive is activated, causing the two clamping rods to move simultaneously closer to the rebar cage until they abut against the side wall. The two clamping rods simultaneously apply a squeezing force to the side wall of the rebar cage towards the center, thus creating a relative force between the two clamping rods." The process involves fixing the reinforcing cage between two clamping rods, stopping the sliding drive, and then activating the lifting device. This causes the fixed frame to move the clamping rods, allowing the reinforcing cage to move closer to or further away from the pile hole, thus achieving the hoisting of the reinforcing cage. When the reinforcing cage is suspended in mid-air, the clamping force of the two clamping rods prevents it from tilting, increasing the stability of the hoisted reinforcing cage and making it less likely to impact the inner wall of the pile hole, thereby reducing the risk of damage to the pile hole. However, during use, the clamping force of the two clamping rods prevents the reinforcing cage from tilting, increasing the stability of the hoisted reinforcing cage. However, when using this hoisting device, after the reinforcing cage is lowered via the support frame, its center position is highly random and difficult to align with the center of the steel casing. This can easily lead to the reinforcing cage deviating, resulting in excessive deviation of the subsequent pile foundation, greatly weakening the pile foundation's bearing capacity and stability.

[0004] Therefore, we provide a steel cage hoisting support mechanism for pile foundations to solve the above problems. Utility Model Content
