Abstract

The invention relates to an assembly type self-resetting middle column connecting device capable of restoring functions, and belongs to the field of structural engineering. The device comprises a square steel tube middle column with two cantilever beam sections, two H-shaped beam sections, a self-resetting device and two connecting device bodies. Welding parts of the joint connecting device are all completed in a factory, the welding seam precision and quality are easier to control, and the construction speed and the construction quality can be improved; according to the anti-buckling idea, upper flange inner cover plates are arranged to be inner cover plates so as to control the buckling amplitude value of the flange cover plates, and lower flange outer cover plates are arranged to be outer cover plates, so that good performance visuality and replacement decidability are achieved; the self-resetting device can guarantee a preset performance design target of the structure dissipating seismic energy and reduce the post-earthquake repair cost. By means of the targeted design, damage positions of the structure under the action of earthquake loads are on the high-strength bolts, connecting plates and other energy consumption components easy to replace, post-earthquake repair is facilitated, and the connecting device meets development requirements of the assembly type steel structure capable of restoring the functions.

Description

technical field [0001] This patent relates to an assembled self-resetting central column connection device with recoverable functions, 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 of various building syste...
