Problems solved by technology

[0004] The unreasonable design of beam-column joints will lead to the occurrence of "strong components and weak joints", which will cause serious earthquake damage to the structure under the action of earthquake load, threatening the safety of people's lives and property
Existing studies have shown that targeted strengthening of beam-column joints or weakening measures such as setting dog-bone weakening areas on specific areas of beams can achieve the purpose of moving plastic hinges outward, thereby protecting beam-column joints and meeting the requirements of "strong joints and weak members". At the same time, the pre-assembled floor and beam sections can be transported to the construction site for assembly, which can greatly save the time of concrete pouring on site, but the combination effect of the floor will increase the bearing capacity and stiffness of the beam-column joints to a certain extent, and will also

Abstract

The invention relates to a function-restorable assembly type wave web beam-column composite joint connection device and belongs to the technical field of structural engineering. The function-restorable assembly type wave web beam-column composite joint connection device is composed of a round steel pipe column with a cantilever beam section, a wave web I-shaped composite beam section and a connecting device between the round steel pipe column with the cantilever beam section and the wave web I-shaped composite beam section. Welding of the joint connection device and assembly of the wave web I-shaped beam section and a composite floor are finished in a factory; weld seam and member qualities are easier to control; the round steel pipe column with the cantilever beam section and the wave web I-shaped composite beam section are assembled only through high-strength bolts and connection plates on site, so that the construction speed and quality are greatly improved; the wave web I-shaped composite beam section can be built on the lower flange connection plate of the round steel pipe column with the cantilever beam section, so that the hoisting difficulty is lowered and on-site assembly and positioning are easy; and through specific design, the structure destroyed positions can appear in the positions of energy dissipation members such as the easy-to-replace high-strength bolts and lower flange connection plate under the action of earthquake load, so that post-earthquake restoring is facilitated, and the function-restorable assembly type wave web beam-column composite joint connection device is adapted to development demands of a function-restorable assembly type steel structure.

Description

technical field [0001] The patent relates to a recoverable fabricated wave web beam-column combined node connection device, 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 is still an extensive construction method based on concrete and on-site masonry, which has caused aggravated 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...
