Abstract

The invention discloses a hoisting method for installation of a reversely inserted part. The hoisting method comprises the following steps that a hoisting tool is machined and manufactured; machining and blanking are carried out according to a design drawing, assembly welding is carried out, it is guaranteed that welding seams are fully welded during welding, and wrap angle welding is carried out on the ends; web member lifting lugs are welded, specifically, the web member lifting lugs are welded on web member parts, and accurate lofting is carried out on the web member lifting lugs according to the mounting angles of the web member parts to ensure that the web member lifting lugs are on plumb lines of the centers of the web member parts; butt joint port positioning devices are welded, specifically, the positioning devices are welded when the web member parts are pre-assembled; the web members are hoisted in place initially; and the web members are matched and connected with the positioning devices. According to the hoisting method for installation of the reversely inserted part, the workload of site construction is greatly saved, a plurality of lifting points are prevented from being welded on the main part, and the finished product of the part is well protected.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a hoisting method for installing reversely inserted components. Background technique

[0002] The steel structure has the characteristics of light weight, high working reliability, and good earthquake and impact resistance. It can design various beautiful structural forms, and build a landscape structure that adapts to the city's beautiful appearance, so as to adapt to the increasing development of bridge structures. To achieve harmony and unity with nature. However, the complexity of the structural form will bring certain difficulties to the construction and production. During the installation and construction process, it is necessary to design and formulate the corresponding installation plan and installation process according to the specific structural form.

[0003] For example, the steel aqueduct project of the main canal of the Pihe River is a beam-ar...
