Description

Technical Field

[0002] In the field of housing construction, precast concrete components generally include wall panels, floor panels, columns, beams, stairs, bay window lines and other elements. These components are manufactured in the factory and transported to the site, and assembled into concrete structures through reliable connection methods. In China, due to its connection technology and geographical reasons, assembled monolithic concrete structures are more common. The composite slab is an assembled monolithic floor slab composed of precast panels and cast-in-place reinforced concrete layers. It is the most commonly used assembled structure in domestic housing construction projects. Precast panels are generally suitable for spans of 3 to 6 meters, suitable for a variety of building layout requirements, and the use of precast panels to undertake part of the formwork function can save formwork materials. In addition, the structural integrity is strong and comparable to cast-in-place structures. However, the hoisting and transportation of precast panels require special equipment and technology to ensure that the panels are not damaged during transportation. At the same time, precise positioning during the hoisting process is also a major challenge. High precision is required during installation, and even small errors may affect the performance of the structure. Generally, the position of the precast panel is marked on the ground, and the hoisting tool is used to lift it above the predetermined position for manual traction and adjustment until the panel falls to the predetermined position. However, in actual operation, due to the large number of specifications and quantities of prefabricated panels, the manual pulling and installation of prefabricated panels often has problems such as inaccurate positioning and low efficiency.
