Assembly type wave web beam-column joint connection device

Abstract

The invention relates to an assembly type wave web beam-column joint connection device and belongs to the field of structural engineering. The assembly type wave web beam-column joint connection device is composed of a round steel pipe column with a cantilever beam section, a wave web I-shaped beam section and a connecting device between the round steel pipe column with the cantilever beam section and the wave web I-shaped beam section. Welded parts of the joint connection device are all finished in a factory; the weld seam accuracy and quality of the welded parts are easier to control; the round steel pipe column with the cantilever beam section and the wave web I-shaped beam section are assembled only through high-strength bolts on site; the fastening work of the bolts is convenient and fast; the construction speed and construction quality are greatly improved; and accordingly, the joint connection device is adapted to development of an assembly type steel structure. Meanwhile, the wave web I-shaped beam section can be built on a lower annular partition board of the round steel pipe column with the cantilever beam section, thus the hoisting difficulty is lowered, the construction progress is accelerated, and moreover, on-site assembly and positioning are easy. The assembly type wave web beam-column joint connection device is good in joint ductility and high in energy-dissipating capacity and bearing capacity, advantages of material saving and high performance of a wave web member can be fully achieved, and application and popularization of the assembly type wave web beam-column joint connection device to the assembly type steel structure are facilitated.

Description

technical field [0001] The patent relates to a beam-to-column joint connection device of an assembled wave web, which belongs to the technical field of structural engineering. Background technique [0002] Since the reform and opening up, my country's urban development has made remarkable achievements. However, urban construction still belongs to the extensive construction method based on concrete and on-site masonry, which has caused serious environmental pollution, serious waste of materials, high construction costs, and low product quality. In April 2015, the "Opinions of the Central Committee of the Communist Party of China and the State Council on Accelerating the Construction of Ecological Civilization" required comprehensive promotion of resource conservation, recycling and efficient use, improvement of the recycling system of renewable resources, promotion of resource utilization of construction waste, and vigorous promotion of green buildings to make buildings green...

Problems solved by technology

[0004] At present, the plastic hinges that are commonly used in beam-to-column connections with prefabricated corrugated webs are relatively close to the column surface when failure occurs, which is likely to cause shear buckling of the column web in the node domain, local buckling of the column flange, and yielding of the beam end plate, which cannot be realized. Quick assembly, long constructi...
