Description
Technical field
The present invention relates to a kind of construction method of steel member, especially a kind of construction party of roof system beam string segmentation installation
Method.
Background technique
Currently, steel construction is in civil engineering work technical field using more and more extensive.But with the roofing of large span
Structure is by more and more applications, and due to the sharply increasing of its self weight, overall structure is faced using function, design rationality and economy
The contradiction that index mutually restricts in order to meet the use function of structure, while reducing dead load, improving the rigidity of structure, is furnished with
The prestressing force beam string structure structure of drag-line is increasingly used in large-scale steel building.Pass through prestressed drag-line and support
The arrangement of bar, the bearing capacity and stiffness of the spatial steel structure of large span have very big improvement.Tension string beam structure can by stress
To be divided into Plane Beam String Structure and Spatial Beam String Structure；Plane Beam String Structure refers to that its structural elements is generally aligned in the same plane
It is interior, and the tension string beam structure based on stress in plane.Plane Beam String Structure can be divided into three according to the shape of upper chord member
Kind citation form: linear type beam string, arch beam string, chevron shaped tension string beam structure.
Nowadays, for various venue steel structure engineerings, typical structure therein is more, especially the field of roof system tension string beam structure
Shop is the novel moulding occurred in recent years.
Cause roof system beam string segmentation installation backstay difficult to install with traditional installation method, operating difficulties, installation
Inefficiency, meanwhile, installation positioning accuracy is not accurate enough, and installation risk is higher.
