Abstract

The invention discloses a wind resistance and vibration reduction device for net rack support joints in the technical field of structural engineering. The device comprises truss columns, joint wind resistance and vibration reduction units, steel supports and a conical net rack. Each joint wind resistance and vibration reduction unit comprises a vibration reduction cylinder, a bearing steel column, a longitudinal vibration reduction assembly and a transverse vibration reduction assembly, and a base is arranged on the bearing steel column. An annular anti-tripping plate is connected into each vibration reduction cylinder, a limiting plate is connected to each bearing steel column in a sleeving mode, and an installation space is formed in each annular anti-tripping plate. The bases are supported through second damping springs, so that the elastic acting force of the second damping springs acts on the bases through the bases, and the effect of relieving the impact force of strong wind on the joints can be preliminarily completed. When the impact force passes through a floating seat and a floating plate, first damping springs are used for buffering and supporting, energy generated by wind power to the joints can be further consumed, and damage to the net rack joints and connecting rod pieces due to vibration generated by the roof is avoided.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a wind resistance and vibration damping device and an assembly method for grid support nodes. Background technique [0002] With the overall development of society, the continuous advancement of architectural science and technology, and the continuous improvement of human life, large-scale, novel and technologically advanced large-span spatial structures have broad application prospects. Large-span space structures are mainly divided into grid structure, reticulated shell structure, membrane structure, suspension cable structure, and shell structure. According to the form, the grid can be divided into planar truss grid, triangular pyramid grid and quadrangular pyramid grid. shelf. Since the natural vibration period of large roof structures is relatively close to the excellent period of wind speed, and most roof structures have the characteristics of light weight, ...
