Description

Technical Field

Background Art

[0002] The modular construction method of super-high pier tower reinforcement is an efficient, fast and quality-controlled construction process suitable for the construction of super-high pier towers. The emergence of this method solves many problems existing in traditional construction methods, while improving construction efficiency and quality and reducing project costs.

[0003] The characteristics of the modular construction method of super-high pier tower reinforcement include modular construction, reinforcement technology, mobility and shortened construction period. First, through modular construction, the construction of super-high pier towers is broken down into multiple modules, each of which is composed of prefabricated steel components, which improves construction efficiency and accuracy; secondly, through reinforcement technology, the modular structure can withstand the expected load and meet the design requirements; then, the method is mobile, that is, the position and order of the modules can be adjusted and changed at any time during the construction process to adapt to the actual project needs; finally, due to the use of modular construction and reinforcement technology, the construction period can be greatly shortened and the demand for personnel is reduced.

[0004] The modular construction method of super-high pier tower reinforcement is suitable for the construction of super-high pier towers in projects such as towering transportation hubs, highways and railway bridges. Through the modular construction and reinforcement technology of pier towers, it can improve construction efficiency and quality and adapt to different construction environments and engineering requirements.

[0005] In the modular construction method of super-high pier tower reinforcement, the prefabricated reinforcement components (super-high pier reinforcement blocks) need to be hoisted accordingly during the construction process. At this time, it is necessary to design a hoisting and fixing sling to fix the prefabricated reinforcement components (super-high pier reinforcement blocks) and cooperate with the lifting equipment to complete the hoisting of the prefabricated reinforcement components (super-high pier reinforcement blocks).

[0006] After searching: Application No. / Patent No. 202223205876.9 discloses an adjustable sling for lifting and assembling steel bars in blocks for super-high piers, which comprises: a beam body and a hanging frame; wherein, the beam body is provided with a lifting lug, and the beam body comprises a middle segment and two side segments, and the two side segments are respectively spliced ​​and fixed on both sides of the middle segment; a plurality of positioning holes are provided at both ends of the side segments along their length direction, and the hanging frame is provided at both ends of the side segments and connected to the positioning holes. The present application realizes a simplified structure of the sling, so that it can be split into three parts for easy transportation when not in use, and at the same time, the position of the sling's lifting point can be adjusted according to the position of the pier body lifting point, thereby improving the technical effect of the adaptability range, thereby solving the problem that the sling used for lifting the steel bar segments of the super-high pier pier body in the related art occupies a large space, is not convenient for transportation, and cannot adjust the sling's lifting point according to the position of the pier body lifting point.

[0007] After analysis, the applicant found that the above technical solution can only be used for the simple placement of prefabricated steel bar components (super-high pier steel bar blocks), and there is a shaking phenomenon after lifting, which causes the prefabricated steel bar components (super-high pier steel bar blocks) to swing synchronously with the lifting equipment, posing certain safety hazards. In addition, there is no corresponding reinforcement design, and there are also risks such as deformation.

[0008] Therefore, based on the above-mentioned problems, the utility model provides a super-high pier steel bar block lifting and fixing hanger with a locking function. Utility Model Content
