Abstract

The invention relates to a steel roof truss, particularly relates to a double-layer spoke type space string-structure steel roof truss and a pre-stressed tensions method thereof, and belongs to the field of a steel structure. The side wall of a stand column is fixedly connected with an outer ring truss through an outer ring support; the outer ring truss is fixedly connected with an inner ring truss through an inner ring support; the bottom of the outer ring truss is provided with outer supporting rods which can be continuously distributed at intervals, wherein the bottom of the outer supporting rod at the innermost end is provided with an outer annular cable fastening device and the bottoms of the other outer supporting rods are provided with outer lower-chord radial fastening devices; the bottom of the inner ring truss is provided with inner supporting rods which are continuously distributed at intervals, wherein the bottom of the inner supporting rod at the innermost end is provided with an inner lower-chord ring beam fastening device; and the bottoms of the other inner supporting rods are provided with inner lower-chord radial fastening devices. The double-layer spoke type space string-structure steel roof truss and the pre-stress tensioning method thereof disclosed by the invention have the advantages of high construction precision, high construction efficiency and low construction cost, and improve the construction safety.

Description

technical field [0001] The invention relates to a steel roof truss, in particular to a steel roof truss with a double-layer spoke type space tension string structure and a prestress tensioning method thereof, belonging to the field of steel structures. Background technique [0002] At present, the large-scale steel structure in the existing technology has relatively low construction accuracy, complex structure, long construction period, unstable overall safety of the steel structure, and certain potential safety hazards. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art, and provides a simple structure, and the whole structure system is divided into two parts, the surrounding structure and the middle structure, which belong to the tension structure system with multi-directional force, and have a structure similar to that of a bicycle wheel spoke. The force transmission mechanism has good spatial integrity and str...
