Precast beam hoisting construction method in warehouse logistics building

Abstract

The invention discloses a precast beam hoisting construction method in a warehouse logistics building, and belongs to the field of construction methods. Climbing type hoisting equipment adopted in themethod comprises a main arm and a rotary bottom disc, and each inter-joint frame can be subjected to precast beam hoisting overall in a simple supporting and hanging beam form and a cantilever hanging beam form. Through the innovative application of the novel hoisting equipment to large warehouse building construction, a brand-new PC beam component hoisting manner is provided, the hoisting and mounting efficiency is improved, and the precast beam hoisting problem in large warehouse logistics buildings with three or more floors is solved. Practice has proved that through the construction method, the construction cost can be obviously saved, construction potential safety hazards can be reduced, and the construction progress can be improved. The method can be widely popularized into PC beamhoisting construction of large-area, long-span, large-floor-height and multi-floor factory buildings and warehouse buildings.

Description

technical field [0001] The invention relates to the field of construction methods, in particular to a construction method for hoisting prefabricated beams in warehouse logistics buildings. Background technique [0002] In recent years, large-scale warehousing and logistics projects have gradually increased. Such projects have a large single-storey area and high storey height. The use of traditional formwork frames requires very high requirements for formwork and support systems, with great safety hazards and long construction periods. Therefore, more and more Many projects have begun to use prefabricated beams and slabs instead of cast-in-place slabs. However, due to the characteristics of large-scale warehousing and logistics projects, there are many prefabricated concrete parts (PC components) and the weight of each component is heavy, making hoisting difficult.

Problems solved by technology

[0002] In recent years, large-scale warehousing and logistics projects have gradually increased. Such projects have a large single-storey area and high storey height. The use of traditional formwork frames requires very high requirements for formwork and support systems, with great safety hazards and long construction periods. Therefore, more and more Many projects began to use prefabricated beams and slabs to replace the construction method of cast-in-place slabs

However, due to the characteristics of large-scale warehousing and logistics projects, there are many prefabricated concrete parts (PC components) and the weight of each component is heavy, making hoisting difficult. Among them, the prefabricated beams of multi-storey large-scale warehousing and logistics projects are particularly prominent

[0003] After analysis and comparison, if the prefabricated beams are hoisted by tower cranes, it is difficult to choose the location of the tower crane and the hoisting efficiency is low, and the supply of large tower cranes in the market is in short supply, making it difficult to rent and the cost is high

If a truck crane is used for hoisting, it is limited by the hoisting radius and height. When the prefabricated beam is prefabricated in situ, the truck crane can only operate around the warehouse area, and the hoisting efficiency is extremely low
