Large-span truss construction method and large-span truss structure

Abstract

The invention discloses a long-span truss construction method and a long-span truss structure. The construction method includes steps that a, preparatory workis performed, specifically, a1, supportingscaffolds are erected, a2, lateral sliding tracks are laid, and a3, longitudinal sliding tracks are laid; b, truss assembly and lateral sliding are performed, specifically, b1, space stabilizing frames are assembled, b2, the space stabilizing frames are subjected to synchronous traction to slide, and b3, the steps b1 and b2 are repeated to form a group frame; c, jacking in position and track transition of the group frame are performed, specifically, c1, the group frame is jacked in position and then supporting legs are installed on the group frame, and c2, the group frame is placed on the longitudinal sliding tracks; and d, longitudinal sliding of the group frame and frame assembly forming are performed, specifically, d1, the group frame is slid, d2, the group frame is jacked up and supports are cut off and the tracks are partially slid, and then finished supports are installed on the group frame, and d3, the steps d1 and d2 are repeated, and a frame assembly is formed.

Description

technical field [0001] The invention relates to the technical field of long-span trusses, in particular to a large-span truss construction method and a large-span truss structure. Background technique [0002] At present, in the field of large-span truss technology, the span of large-span space structures is getting larger and larger, the shape is becoming more and more novel and unique, and the structure is becoming more and more complex. Higher and higher. Faced with the increasing application of long-span steel roof trusses, traditional construction methods can no longer meet the needs of construction, and changes in construction technology have become inevitable. [0003] At present, there are mainly the following methods for the installation of long-span steel structure trusses: [0004] 1. Overall lifting technology, the trusses are transported to the site in sections, and the assembled tire frame is installed on the ground directly below the installation position of...

Problems solved by technology

[0008] Based on this, the present invention proposes a large-span truss construction method. The large-span truss construction method aims to solve the technical problems that the truss construction method in the prior art is difficult to match the complex space conditions, and the construction cost is high and the site requirements are too high.
