A method for manufacturing super-large variable cross-section cable tower steel parts

Abstract

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. Arrange the stirrups horizontally and transversely according to the designed spacing, tie the longitudinal reinforcements arranged horizontally and longitudinally on the stirrups according to the designed spacing, and bend the intersection of the stirrups and the bending edge along the axial and circumferential directions of the bending edge respectively. Fold it to form a ring of variable cross-section steel mesh pieces corresponding to the lower and upper sections of the cable tower structure. The steel mesh pieces of different sizes corresponding to the same section of the cable tower are bundled together in sequence according to the above process. The tendons are bound and fixed into a complete section of steel bars; the bent edge refers to the connection of the points corresponding to the same vertical edge of the cable tower on the stirrup. The manufacturing method of the invention is simple and efficient, greatly improves the accuracy of steel bar parts, reduces the man-hours of welding construction, improves the efficiency of assembly 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...
