Abstract
The invention discloses a kind of truss installa-tions to dock measurement method, including step：According to engineering design requirements, moulding bed is positioned and has set up, and marked around the moulding bed；Truss position is positioned according to engineering design requirements, selectes main couple, and feature measurement is carried out to the main couple；Adjust the main couple docking splice point and axis interface point to predeterminated position, and complete the splicing between truss；Repeated measurement and adjustment are carried out to entire spliced truss, until adjusting truss to best design position；The present invention, by carrying out the measurement of necessary data to truss, ensures that truss can be attached to accurate location according to engineering design requirements, can effectively promote the quality of engineering completion in truss installa-tion docking operation.
Description
Technical field
The present invention relates to steel-structure installation measurement fields more particularly to a kind of truss installa-tion to dock measurement method.
Background technology
Truss is structure made of one kind is articulated and connected at both ends each other by rod piece, is made of straight-bar general with three
The plane or space structure of corner shaped elements, truss member are primarily subjected to axial tension or pressure, so as to make full use of material
Intensity saves material when span is larger than solid web girder, mitigates dead weight and increases rigidity；In some Larger Engineering Projects,
Most common is usually steel truss, and steel truss is compared with the girder steel of steel flanged beam, its main feature is that replacing the edge of a wing with chord member and with abdomen
Bar replaces web, and is interconnected web member and chord member by gusset plate weld seam or other connections at each node;Sometimes
Can without gusset plate and directly by each rod piece mutually welding in this way, plane girder integrally by it is curved when moment of flexure show as upper and lower string
The axial compression and tension of bar, shearing then show as the axial compression or tension of each web member.
