Technical Field
The utility model belongs to the technical field of the building. In particular to a novel support-free assembled beam column node.
Background
In the frame structure, the node is the pivot of the structure force transmission, and plays the role of transmitting and distributing internal force and ensuring integrity. Under the action of earthquake, the core area of the node is easy to generate shearing brittle failure. Once the node is broken, the structure is in an extremely unfavorable stress state, and even the whole structure collapses.
The connection of the beam-column joints affects the overall performance of the fabricated frame structure. Traditional assembled connected node generally adopts the cast-in-place of node, reaches the purpose of strong node. Some students also carry out related research on the structure system, and the node of the structure system consists of a key slot, a U-shaped steel bar and cast-in-place concrete, so that the traditional mode of anchoring the longitudinal steel bar of the beam in a node area is changed into the mode of realizing lap joint with the prestressed steel bar at the end of the precast beam in the key slot, namely the plastic hinge area at the end of the beam.
