Fabricated type anti-buckling inversed L-shaped web shear piece combined joint connecting device capable of recovering functions

Abstract

The invention relates to a fabricated type anti-buckling inversed L-shaped web shear piece combined joint connecting device capable of recovering functions, and belongs to the field of structural engineering. A fabricated type anti-buckling inversed L-shaped web shear piece combined joint is composed of a square steel pipe column with a cantilever beam segment, an I-shaped combined beam segment and a group of combined connecting devices; pouring of concrete plates in the combined beam and welding parts of rivets and a joint connecting device can be completed in a factory, the welding seam precision and quality are controlled easier, and the construction speed and quality are greatly improved; an upper flange inner cover plate of the combined connecting device is arranged into an inner cover plate type by using an anti-buckling idea for flange cover plate buckling amplitude value control; a lower flange outer cover plate is arranged into an outer cover plate type, and good performance visuality and replacement decidability are achieved; and structural damage positions under the seismic load action can occur in energy dissipation member positions such as high-strength bolts and connecting plates which are easy to replace through targeted design, post-seismic repair is facilitated, and the fabricated type anti-buckling inversed L-shaped web shear piece combined joint connecting device is applied to development requirements of a fabricated type steel structure capable of recovering the functions.

Description

technical field [0001] The patent relates to a recoverable function assembled anti-buckling inverted L-shaped web shear member combined node connection device, which belongs to the technical field of structural engineering. Background technique [0002] With the acceleration of the urbanization process, the development of the construction field and the continuous improvement of the technical level, coupled with the impact of environmental pollution and resource waste, the defects of poor environmental protection in the traditional building system are gradually exposed, and the green fabricated steel structure has begun to become a building The main types of systems. Compared with the traditional system, this system has significant advantages in terms of construction quality and construction efficiency. "Building blocks" is a representative construction method, which greatly speeds up the construction speed and saves project funds. Applying it to the design and development ...
