Abstract

The invention provides a hoisting method for a large-span hinged type herringbone steel arch. The hoisting method comprises the steps of conducting hinge joint connection, setting hoisting points, installing hoisting rings, determining the lengths of hoisting steel wire ropes, hoisting and the like. According to the hoisting method for the large-span hinged type herringbone steel arch, due to integral and multipoint hoisting, the technical problems that hinge pin installation in high attitude is difficult, high in construction cost, low in working efficiency and the like are effectively solved. In addition, due to the facts that two hoists are used for hoisting, multipoint hoisting is adopted, and the hoisting points are set reasonably, the situation that the herringbone steel arch deforms due to lack of rigidity in the hoisting process is avoided. Due to the fact that the hoisting steel wire ropes with suitable lengths are selected, the installation angle of the herringbone steel arch is effectively controlled, and two column feet is made to be positioned on bases easily.

Description

technical field

[0001] The invention relates to a hoisting method, in particular to a hoisting method of a large-span articulated herringbone steel arch. Background technique

[0002] The herringbone steel arch structure was mostly seen in the 1960s and 1970s, but this kind of structure is rare in China now. Herringbone steel arch frame includes component I and component II, each part is welded H-shaped steel, the top of component I and component II is hingedly connected, the two column feet of the arch frame are hingedly connected with the base on the embedded plate, multi-pronged arch frame Form the main frame of the plant. The span between the two columns of many large factory buildings is generally more than 50 meters, and the roof elevation is more than 30 meters.

[0003] At present, there are two ways to install this large-span articulated herringbone-shaped steel arch: one is sub-piece hoisting, that is, component I and component II are hoisted separately and then ...
