Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and specifically discloses a roof steel truss integral assembly support frame. Background Technology

[0002] With the development of the construction industry, more and more roofs are adopting spatial steel truss structures. For the hoisting of large-span steel trusses, segmented hoisting is used. First, the steel truss sections need to be assembled using a horizontal assembly method. Then, the steel truss sections are assembled into a complete truss. During the assembly of the steel truss sections into a complete truss, the steel truss sections need to be supported by a special jig. Most steel truss assembly jigs are made by welding steel profiles. The support rods are supported under each node of the steel truss section to be assembled. For multi-shaped or curved trusses, different support nodes under the steel truss sections need to be supported by jigs of different heights. In order to reduce the workload of jig fabrication, a jig that can be easily adjusted in height according to the required support height of different support nodes under the steel truss sections is needed, thereby reducing installation costs and increasing the stability of steel truss assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a roof steel truss integral support frame, which has a stable support structure and allows for easy adjustment of the support height of the frame according to different support nodes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:
