Construction method for large radial arc-shaped frame body structure

Abstract

The invention discloses a construction method for a large radial arc-shaped frame body structure. The construction method comprises the steps that a, the frame body structure is divided into multiple vertical construction areas; b, vertical trusses in each vertical construction area are divided into multi-span truss sections; c, measurement and positioning are performed, and a first layer of truss sections in each vertical construction area are assembled; d, a first layer of annular rod member is arranged among each first layer of truss sections, so that the first layers of truss sections in all vertical construction areas are connected into a whole to form a first layer of radial arc-shaped frame body structure; e, the step c and the step d are repeated, so that the truss sections and annular rod member of each layer of radial arc-shaped frame body structure are assembled layer by layer until the last layer of radial arc-shaped frame body structure is assembled; and f, a top connection truss is arranged. According to the construction method disclosed by the invention, area-separated and annular section-separated construction is adopted by the frame body structure, so that the construction difficulty is reduced; and the truss sections in each vertical construction area are synchronously constructed layer by layer, and closure is performed after hoisting and assembling at each layer are finished, so that an integrally stable stress system is formed.

Description

technical field [0001] The invention relates to the field of steel structure buildings, in particular to a construction method for a large radial arc frame structure. Background technique [0002] Due to the large arc, many bending and torsion components, complex curved surfaces, and high-altitude construction, the large-scale radial arc-shaped steel structure has a curved space shell shape as its main body. The overall measurement and control of the structure is large, and the measurement accuracy is high. Therefore, it is impossible to use conventional high-altitude measurement methods to measure Positioning and construction are more difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precision and easy-to-operate construction method for a large radial arc frame structure. [0004] In order to achieve the above-mentioned technical effects, the present invention discloses a construction method for a la...
