Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering and construction technology, in particular to a fine-tuning structure for hoisting and butting prefabricated risers. Background Technique

[0002] The prefabricated risers of a certain project's pipe shaft are for the air conditioning water system from the 3rd floor to the 29th floor above ground, and the prefabricated riser pipe shafts are distributed in the air conditioning machine rooms of the north and south core tubes. The prefabricated risers of this project are welded air conditioning water pipes with DN>100. The distribution positions of the pipe shafts and the pipe information are as follows:

[0003] After the prefabricated risers are in place, the shaft openings of the civil construction operation layer are closed and protected. If there is a situation of misalignment, fine-tuning work is carried out in the lower layer in a timely manner. The traditional hoisting and butting of prefabricated risers usually includes the following steps: First, use a crane or hoisting equipment to lift the riser to a position close to the predetermined position and carry out preliminary positioning. During the hoisting process, gradually adjust the position of the riser, and ensure that the riser butt joint is in the designed position through pads or adjustment devices. Then use a level and a vertical instrument to confirm the horizontal and verticality of the riser and carry out fine-tuning. When the riser butt joint is accurately in place, use a fixing device to firmly fix it to ensure its stability. Although the above-mentioned hoisting and butting operations of prefabricated risers are widely used in many projects, there are also some defects and challenges: 1. Difficult adjustment: There is more dependence on manual operation in the traditional method, resulting in low accuracy, especially in complex or large-scale projects. 2. Long butting operation time: The traditional butting operation may require a long time for adjustment and fixation, affecting the construction progress. Especially when multiple workers need to cooperate, it increases the operation complexity and time consumption; 3. Great potential safety hazards: There may be operation risks in the traditional hoisting process, especially during high-altitude operations, and workers need to adjust and fix at unstable positions; 4. Large error accumulation: In the process of multiple adjustments, there may be a problem of error accumulation, resulting in insufficient final docking accuracy and unable to achieve accurate docking in actual operation.
