Steel box beam transferring auxiliary device and operation method

Abstract

The invention discloses a steel box beam transferring auxiliary device and an operation method. The device comprises a variable cross-section H-shaped steel beam, a lifting hook and lifting lugs, wherein an upper flange plate of the variable cross-section H-shaped steel beam is arranged horizontally; a lower flange plate is divided into three sections and is of an opened U-shaped structure; the middle section of lower flange plate is arranged horizontally and is located in the center of the lower flange plate; the distances between the left section and the right section of the lower flange plates and the upper flange plate are gradually reduced along two end directions of the upper flange plate; a web is arranged between the upper flange plate and the lower flange plate and is used for connecting the upper flange plate and the lower flange plate; the lifting hook is arranged under the middle section of lower flange plate; the two lifting lugs are arranged on the upper surface of the upper flange plate of the variable cross-section H-shaped steel beam; and the distance between each lifting lug and one end of the adjacent upper flange plate is equal. The device is simple to install,low in cost, high in utilization ratio, and capable of effectively solving the problem that a steel box beam cannot be transferred due to a narrow workshop channel space.

Description

technical field [0001] The invention belongs to the technical field of building steel structures, and in particular relates to a steel box girder transfer auxiliary device and an operation method. Background technique [0002] The ultra-long and ultra-wide steel box girder has a large cross-section, thick plates, and high weld quality requirements, so it chooses factory production. The factory has complete production equipment, and the process from blanking to pre-assembly can be integrated, with high efficiency and easy quality details. control. After the steel box girder assembly is completed in the factory building, there are equipment production line areas, raw material stacking areas, blanking areas, assembly areas, welding areas, finished product stacking areas and other areas arranged on both sides of the plant. Steel box girder processing plant such as figure 1 As shown, the factory building as a whole is a large rectangle, and the two small rectangles on the left ...
