Description

Technical Field

[0001] This utility model mainly relates to the field of steel cage construction technology, specifically a rapid suspension structure for a large-diameter steel cage wellhead. Background Technology

[0002] During the construction of pile foundations for high-rise buildings, a wellhead is typically drilled in the ground, and a steel casing is placed inside the wellhead. A reinforcing cage is then placed inside the steel casing, and cement is poured in to form a solid pile foundation. When the load-bearing requirements are high, a crane is often used to suspend and place a large-diameter reinforcing cage. This can easily cause the reinforcing cage to sway inside the wellhead, interfering with construction and potentially causing it to tilt and affect the load-bearing capacity of the pile foundation. Therefore, a suspension structure is set up at the wellhead to assist in the placement of the reinforcing cage. However, the traditional suspension structure cannot adjust the position of the suspension end and is not compatible with the use of different types of reinforcing cages.

[0003] Existing technology uses fixed longitudinal beams and movable crossbeams to allow for bidirectional horizontal adjustment of four sets of suspension rods, facilitating the suspension of different types of rebar cages. However, the fixed longitudinal beams, movable crossbeams, and suspension rods are connected by detachable connectors, requiring independent disassembly and installation for each adjustment. Furthermore, it cannot adjust multiple suspension rods simultaneously, resulting in slow construction speed. Utility Model Content
