According to key points of the technical scheme, the radian box type member includes an upper wing plate with a radian, a lower wing plate with a radian, and inner webs and outer webs which are located on the two sides of the upper wing plate and the lower wing plate, the upper wing plate, the lower wing plate, the inner webs and the outer webs are enclosed to form a box type structure, the upper wing plate and the lower wing plate arearranged in parallel, a longitudinal stiffening plate keeping in a state perpendicular to the upper wing plate and the lower wing plate is arranged between the upper wing plate and the lower wing plate, the upper end and the lower end of the longitudinal stiffening plate are connected with the middle parts of the upper wing plate and the lower wing plate correspondingly, the longitudinal stiffening plate is arranged in parallel with the inner webs and the outer webs, the side, facing the outer webs, of the longitudinal stiffening plate is connected with a plurality of sets of partition platesconnected with the outer webs, the partition plates are perpendicular to the upper wing plate, the lower wing plate and the longitudinal stiffening plate, the multiple sets of the partition plates are arranged at intervals in the length direction, each set of the partition plates is provided with two partition plates, the space between every two set adjacent partition plates is greater than the space between the two partition plates in each set, and good structural strength and good support performance are achieved.
Description
technical field [0001] The invention relates to the technical field of steel structural components, in particular to a curved box-shaped component, a manufacturing process and an assembly method. Background technique [0002] In sports centers, airports and other large buildings, novel and unique shapes such as hyperbolic, in-plane curved arcs, and space curved arcs are continuously applied, which fully embodies human creativity and the beautiful pursuit of architectural artistry. [0003] At the same time, in order to meet the requirements of architectural design, a large number of special-shaped steel structural components are used, which puts forward higher requirements for the processing and production of steel components. When making steel structures, the processed box-shaped components will be divided into components of different shapes and sections according to the different load-bearing equipment or skeletons. [0004] However, the current special-shaped box-shaped ...
