Embodiment 1

[0041] Construction preparation:

[0042] 1. Equipment selection and layout. According to the self-weight and size of the steel truss, combined with the situation of the lifting equipment 12 in the market and the contract cost requirements, the type and quantity of the lifting equipment 12 are determined. According to the self-weight and size of the steel truss, calculate the mass of the steel truss to be slid and the friction force during the sliding process, select the models of hydraulic jacking equipment, hydraulic pump source equipment, computer synchronous control and sensor detection system, and determine the Arrangement of push points and sliding scheme. During the sliding process, the thrust exerted by the pusher and the friction force F between all the sliding shoes 2 and the slide rails are balanced. After force analysis and calculation, due to the heavy sliding weight of the middle track, a push point is arranged every two trusses on the middle track.

Abstract

The invention discloses a hoisting and sliding construction method of a steel truss structure with large-span and unequal height supports, in particular a hoisting and sliding construction method of a steel truss structure with large-span and unequal height supports in the field of building construction, including the following aspects Step 2: A. Set the support on the steel truss, install sliding equipment and pushing equipment; B. Divide the truss, assemble it into shape, lift the steel truss to the specified height, lift one truss each time, and then lift The truss in place is spliced ​​with the truss that has been hoisted in place before it, and the previous truss is slid by sliding equipment and pushing equipment, and after the space within the operating range of the hoisting equipment is vacated, the steel truss of the truss is hoisted To the designated position; C. After the sliding is completed, remove the support. The hoisting and sliding construction method of the large-span and unequal-height steel truss structure of the application can reduce the level threshold and energy consumption of hoisting machinery, reduce the pre-assembly area, reduce component deformation, and improve the overall forming quality of the structure.

Description

technical field [0001] The invention relates to a hoisting and sliding construction method of a steel truss structure with large span and unequal height supports, in particular to a hoisting and sliding construction method of a steel truss structure with large span and unequal height supports in the field of building construction. Background technique [0002] With the development of building construction technology, steel structures are increasingly favored by the market and widely used in various building structures. At the same time, the complex steel structure system can be decomposed by components to realize the design, processing, storage and transportation, and installation of streamlined production lines, increase the proportion of factory production, reduce the time cost of on-site wet operations and maintenance, and reduce the cost caused by manual operations. Original deviation; gradually changing the traditional agricultural model of "on-site pouring" in the con...
