Problems solved by technology

[0003] Due to the large construction area of ​​the large-span steel structure, the self-heaviness of a single roof truss requires a large area to be erected, resulting in a prolonged construction period; if the split-panel hoisting is used, a large-tonnage crane is required, resulting in a prolonged construction period and increased costs

Embodiment 1

[0015] An overall sliding construction process for a large-span steel structure tire frame, comprising the following steps:

[0016] 1. Build a fastener-type steel pipe sliding and assembled tire frame, install the sliding track and propeller control system, use fastener steel pipes to tie the sliding track every 6m, and check the stability of the sliding track.

[0017] 2. The truss is hoisted in sections, hoist the hoisting member to the specified position, fix it after correction, install two trusses on the assembled tire frame as the sliding unit, install the hydraulic control system and the hydraulic operating system, and the two trusses are integrated at both ends Slide towards the middle.

[0018] 3. Debug the thruster control system. The truss sliding unit slides to the design position with the tire frame as a whole, unloads and fixes it on the structural column, corrects the position of the truss, assembles the tire frame and slides back, and prepares for the assembly...

Abstract

The invention discloses a large-span steel structure jig frame integrity slip construction process. The process includes the follow steps: building a fastener-type steel tube slip assembly jig frame, and installing a slip rail and a propeller control system; lifting trusses in a section manner, lifting a lifting component to an assigned position, fixing the lifting component after correction, arranging two trusses on the assembly jig frame to be served as a slip unit, installing a hydraulic control system and a hydraulic operation system, and allowing the two trusses to integrally slip from tow ends to a center; debugging the propeller control system, unloading the truss slip unit and fixing the truss slip unit to a structure column after being integrally slipped to a preset position with the whole jig frame, correcting the positions of the trusses, allowing the assembly jig frame to inversely slip, and preparing assembly and slip of the two trusses; and demolishing the slip rail and the propeller control system. According to the large-span steel structure jig frame integrity slip construction process, a slip unit is arranged under the assembly jig frame; after the slip unit is installed, the slip unit and the whole jig frame are slipped to the preset position along the rail; the large-span steel structure jig frame integrity slip construction process is safe and reliable; a large area jig frame can be avoided; and the construction period can be shortened.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and in particular relates to an integral sliding construction process of tire frames of large-span steel structures. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, in order to build larger, stronger and longer various ultra-large complex structures to meet people's pursuit of living space. Large-span steel structures were developed accordingly. The long-span steel structure has the characteristics of heavy single-panel weight, complex architectural shape, the stress state during the construction process is far from the stress state of the design and molding, and the cross-construction with the concrete structure. Steel structure residence represents a new model of future residential development. Compared with traditional brick-concrete structure and reinforced concrete frame structure, it has obvious advantage...
