An anti-pull pot-type column connection device and its construction method, comprising an upper steel column and a lower steel column; the bottom of the upper steel column is provided with a tenon, and the bottom surface of the tenon is a convex curved surface protruding downward; the vertical side of the tenon A group of perforations are arranged on the wall at intervals along the circumferential direction, and bullet blocks are correspondingly arranged in the perforations; elastic members for ejecting the bullet blocks are arranged in the tenon, and the elastic members are fixedly connected with the inner side of the bullet blocks; the top of the lower steel column There is a mortise corresponding to the tenon; the bottom surface of the mortise is a concave surface adapted to the bottom of the mortise; the tenon is inserted into the mortise, and the top of the mortise exceeds the top of the mortise, and the bullet on the tenon is located in the mortise ; On the inner side of the top of the tenon groove, at the position above the spring block, a horizontal card edge is provided along the circumferential length, and a distance is left between the card edge and the tenon. The invention solves the technical problems of complicated construction process, low construction efficiency and unguaranteed anti-seismic performance of the traditional connection device.
Description
technical field [0001] The invention belongs to the technical field of structural engineering, in particular to an anti-pull pot-type column connection device and a construction method thereof. Background technique [0002] Prefabricated steel structure buildings have many advantages such as high construction efficiency, low environmental pollution, detachable, recyclable and easy maintenance, and become a main theme of future building development. However, most of the current assembled steel structure buildings are connected by bolts or welds, which reduces the construction efficiency to a certain extent; in addition, the traditional bolts or welds cannot dissipate seismic energy, and the seismic performance of the joints cannot be achieved. ensure. Contents of the invention [0003] The purpose of the present invention is to provide an anti-pull pot-type column connection device and its construction method, to solve the technical problems of complex construction process...
