Problems solved by technology

[0004] In order to solve the technical problems in the prior art that when the large-span hinged herringbone steel arch frame is hoisted as a whole, the arch frame is easily deformed, cannot meet the technical requirements of installation, and is difficult to install. The purpose of the present invention is to provide a large-span hinged The hoisting method of herringbone steel arch frame adopts integral and multi-point hoisting, which solves the technical problem that the arch frame is easy to deform and meets the construction requirements, and the hoisting method is simple to operate and has high working efficiency

Embodiment Construction

[0027] Preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a schematic diagram of a herringbone steel arch structure, such as figure 1 As shown, the herringbone steel arch 1 includes symmetrically arranged components I101 and II102. Both components I101 and II102 are welded H-shaped steels, and may also be made of other suitable materials. The tops of the component I101 and the component II102 are hingedly connected by a pin, and the distance between the two columns 2 of the component I101 and the component II102 is the design width; after hoisting, the two columns 2 and the base on the embedded plate 3 4 hinged connections. The herringbone steel arch 1 is hoisted according to the following steps:

[0029] Step 1. If Figure 4 As shown, on the ground, the tops of member I101 and member II102 of the herringbone steel arch 1 are hinged and connected by pins to assemble...

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 ...
