Title:
ASSEMBLED SELF-RESTORING CIRCULAR COMPOSITE CONCRETE-FILLED STEEL TUBE JOINT
Document Type and Number:
WIPO Patent Application WO/2019/119686
Kind Code:
A1
Abstract:
An assembled self-restoring circular composite concrete-filled steel tube joint comprises a circular steel tube column (1) and an H-shaped steel beam (2). Steel bars (9) pass through the circular steel tube column (1). The circular steel tube column (1) comprises an upper steel tube column (3), a central insert column (4), and a lower steel tube column (5). The upper steel tube column (3) and the central insert column (4) are connected by an upper sleeve connecting member (6). The central insert column (4) and the lower steel tube column (5) are connected by a lower sleeve connecting member (7). The H-shaped steel beam (2) is connected to the circular steel tube column (1) by the upper and lower sleeve connecting members (6, 7). All of the components can be machined in a factory and bolted together on site to form a joint, thereby avoiding a possible quality defect caused by on-site welding. The design of the joint restrains concrete from cracking during an earthquake, such that the joint suffers no damage during a light earthquake, quickly recovers from deformation after a medium earthquake, and can be precisely removed and rapidly replaced after a severe earthquake.
