Description

Technical Field

[0001] The invention belongs to the technical field of building hoisting equipment, and in particular relates to hoisting equipment and a method for installing and constructing a building steel structure. Background Art

[0002] In recent years, with the vigorous promotion of green buildings and prefabricated buildings in my country, steel structure buildings with the characteristics of green buildings and prefabricated buildings have developed rapidly, while most of the on-site construction technologies and safety measures of steel structures are still in traditional forms. In particular, most of the current projects have short construction periods, huge welding volumes, harsh construction environments, and many cross-operations of various types of work. Traditional construction methods seriously affect construction quality and personnel safety. In addition, in the steel structure construction industry, many large steel structure components need to be installed and constructed through operating platforms during the construction process.

[0003] For example, in a Chinese invention patent application with application publication number CN115012519A and application publication date 2022.09.06, a method for installing a super high-rise building steel structure is disclosed, including the following steps: S1: pre-preparation, installing a tower crane at the construction site, and counting the number of steel plates, and stacking them for acceptance; S2: component fixing, placing the longer steel plates in the steel structure, and fixing them with fixing equipment, while installing the shorter steel plates in the middle of the two longer steel plates, and installing different numbers of short steel plates in sequence according to the required shape of the steel structure, and adjusting the horizontality between the short steel plates and the long steel plates by positioning adjustment. The trial lifting step of the present invention can ensure the stability of the rigging, prevent the steel structure from slipping during lifting, causing safety accidents, improve the safety performance of steel structure construction, and prevent safety accidents caused by ground workers not completely detaching their hands from the hook when hanging, thereby improving the safety of lifting. However, in the installation method used for the construction of super high-rise building steel structures, the tower crane equipment carries loads through lifting ropes to achieve the lifting of steel plates.
