Method for assembling complicated steel structure junctions

Abstract

The invention relates to a method for assembling complicated steel structural junctions. The method for assembling the complicated steel structural junctions comprises the steps of designing a spatial junction structure to obtain angle parameters and location data of all steel beam joints; then using spatial junction installation equipment; the spatial junction installation equipment comprises a machine frame; a pedestal fixer and a steel beam joint fixer are arranged on the machine frame; the pedestal fixer and the steel beam joint fixer make relative rotation about the center of the pedestal fixer; the steel beam joint fixer is provided with five freedom degree driving devices; converting the location data and the angle of the steel beam joint, which are obtained in a design way to the motion displacements of the five freedom degree driving devices, finally enabling the steel beam joint fixer to reach the location of the designed steel beam joint in space, installing a spatial junction pedestal on the pedestal fixer, and installing the steel beam joint on the spatial junction pedestal by directly taking the steel beam joint fixer as an installation reference; continuously implementing the operations till completing the installation of the junctions in the whole space.

Description

technical field [0001] The invention relates to a complex steel structure node assembly method for building. Background technique [0002] Spatial joints are commonly used components in long-span steel structure buildings, which play the role of fixing the position of steel beam joints and carrying weight. As the existing buildings tend to be complex, the positions and angles of the joints of the steel beams connected to each space node can not help but be the same according to different positions, which brings inconvenience to the assembly. The existing assembly method is based on the base of the space node. After complex physical calculations and changes in the actual shape, the position of the steel beam joint is finally located by adding various reference plates and installed on the base of the node. This method is extremely complicated. Firstly, the positions of the steel beam joints must be reversely calculated to obtain the positions of the reference planes and refer...

Problems solved by technology

This method is extremely complicated. Firstly, the positions of the steel beam joints must be reversely calculated to obtain the positions of the reference planes and reference plates, and then the actual installation of the reference plates requires extremely high requirements for the installation of the reference plates. Due to the need for multiple reference plates Combined use, the final position error is relatively large; moreover, because the angle and position of each steel beam joint are different, it cannot be reused, and the installation process of each steel beam joint is a complicated process, which greatly extends the space Node assembly time
