Hoisting structure and hoisting method for prefabricated panel with high height-thickness ratio

Abstract

The invention relates to the technical field of hoisting construction of panels and discloses a hoisting structure and a hoisting method for a prefabricated panel with high height-thickness ratio. Thehoisting structure comprises a pretightening device arranged on the prefabricated panel and hoisting equipment of the prefabricated panel; the pretightening device consists of pretighening units which are horizontally arranged along the surface of the prefabricated panel in parallel; each group of pretightening units comprise a pretightening rope, a chain block, a first flying ring arranged on atop beam of the prefabricated panel, second flying rings arranged at two ends of a bottom beam of the prefabricated panel as well as a third flying ring at the middle part of the bottom beam of the prefabricated panel; one end of each pretightening rope is fixedly connected with the corresponding third flying ring; the other end of each pretightening rope upwards penetrates through the corresponding first flying ring, continuously faces downward and is connected with the corresponding second flying ring through the chain block; the hoisting equipment is fixedly connected with the top beam of the prefabricated panel through a hoisting rope. The hoisting structure and the hoisting equipment disclosed by the invention have the advantages of simple structure, no damage to the prefabricated panel and safety and stability in hoisting.

Description

technical field [0001] The invention relates to the technical field of wall board hoisting construction, in particular to a hoisting structure and a hoisting method of a prefabricated wall board with a large height-thickness ratio. Background technique [0002] In recent years, the development of prefabricated buildings has become more and more mature, and their applications have become more and more extensive. At present, in the field of civil engineering, most of the prefabricated components are not too large in size, and the lifting and installation process is simple and safe. [0003] Generally, it is directly hoisted on the floor by a crane with a sling or a hook. The lifting point on the wall panel is generally set on the top hoisting beam or bottom beam of the wall panel. This hoisting method is simple and easy to operate, but it is only suitable for smaller sizes For small prefabricated components, for prefabricated wall panels with a height-to-thickness ratio greate...

Problems solved by technology

[0006] The technical problem to be solved is: for prefabricated wallboards with relatively large height and thickness, the existing method of setting the lifting points on the prefabricated wallboards and the method of using simple metal brackets has poor lifting safety, or prone to rollover, or prone to The excessive tension caused by gravity and other factors will cause the wall to be damaged; the method of setting the hoisting point on the support frame has a complex structure, high cost, and heavy self-weight, which greatly increases the hoisting weight and improves the lifting load requirements. increased construction costs
