The connection at the side plate in this node greatly strengthens the stiffness and bearing capacity of the node domain, thus realizing "strong node, weak member", and the angle steel member welded on the side plate is used as a bracket when the steel beam is hoisted, giving the site Installation brings great convenience. This node is a beam-column joint form suitable for multi-high-rise residential systems. It is an environmentally friendly and energy-saving node form that can implement rapid and efficient construction of residential buildings. It has far-reaching significance for the development of multi-high-rise residential systems in the future.
