Manufacturing method of reinforcing steel bar component of super large variable cross-section cable pylon

Abstract

The invention relates to a manufacturing method of a cable tower reinforcement skeleton, in particular to a reinforcing steel bar component of a super large variable cross-section cable pylon. The manufacturing method includes the steps: arranging stirrups horizontally and horizontally according to the designed spacing, binding the longitudinal bars arranged along the horizontal longitudinal direction on the stirrups according to the designed spacing, bending the stirrups at the intersection of the stirrups and the bending edge along the axial direction and the circumferential direction of thebending edge respectively, so as to form a ring corresponding to the lower large and upper small variable cross-section reinforcing bar mesh of the cable tower structure, sequentially nesting the reinforcing bar mesh of different sizes corresponding to the same segment of the cable tower according to the flow chart, and binding and fixing the reinforcing bar mesh into a complete section of reinforcing bar parts through the bracing hook bars; the bending edge finger stirrup corresponds to the connecting line of the points of the same vertical edge of the cable tower. The manufacturing method of the invention is simple and efficient, greatly improves the precision degree of the reinforcing steel bar components, reduces the man-hour of welding construction, improves the efficiency of assembling construction, and has great popularization value.

Description

technical field [0001] The invention relates to a method for manufacturing a steel bar skeleton of a cable tower, in particular to a method for making a steel bar part of a super-large variable-section cable tower. Background technique [0002] Transportation is the artery of the national economy, and bridges are an indispensable and important part of transportation facilities. In the past ten years, with the development of the national economy, the advancement of science and technology, the improvement of industrial levels, the emergence of new building materials, construction technology With continuous innovation, design theory and calculation methods have advanced by leaps and bounds, and bridge engineering has also developed rapidly. In order to overcome the obstacles of high mountains, deep valleys and vast waters, higher and higher requirements are put forward for the length and span of bridges. In the construction of cable-stayed bridges and suspension bridges, the br...
