Embodiment Construction

[0021] Specifically, a bridge steel tower column with a curved shape, the steel tower column is formed by connecting several curved steel tower segments, and the curve shape of each segment is in line with the curve of the overall position of the steel tower column corresponding to the line. The inner and outer wall plate units (13, 9) and the inner and outer web plate units (11, 10) in the steel tower segment in the plate thickness direction are arc-shaped curves; the side wall plate units (8) on both sides in the plate width direction are arc-shaped The arc shape matches the curve shape of the inner and outer wall panels and the inner and outer web plates; at the same time, the arc curve corresponds to the curve shape of the steel tower column as a whole. The steel tower segment is composed of an inner wall plate unit (13), an inner web plate unit (11), an outer wall plate unit (9), an outer web plate unit (10) and side wall plate units (8) on both sides, a transverse The l...

Abstract

The bridge steel column in curve profile consists of several steel column sections in curve profile, and the curve profile of each section is corresponding to that one the whole steel column. The curve profile controlling method for the bridge steel column includes controlling the curve formation of plate units, controlling the tool set for assembling, etc. The said technology has been used successively in building the third Nanjing Changjiang bridge.

Description

technical field [0001] The invention belongs to the technical field of bridge construction in fixed buildings, in particular to a method for controlling the curve of a curved steel tower column in a steel structure bridge. Background technique [0002] Steel structure products meet the needs of environmental protection and resource reuse. They have a series of advantages such as high strength, small dead weight, good seismic performance, fast construction speed, low foundation costs, high degree of industrialization, and beautiful appearance. They are widely used in many major projects. Steel structures have made certain achievements. Especially in the United States, Japan and other developed countries, in the construction of large and super large bridges, in addition to steel box girders, most of the bridge towers also use steel structures, which not only improves the beauty of the bridge, shortens the construction period of the bridge, but also Produced huge economic and ...
