Abstract
The utility model discloses a connection node of a steel rib and a steel frame. The connection node is designed to resolve the problem that structure formed by mutual interference of the steel rib and the steel frame beam corresponding embedding part in the connection process of the steel rib and the steel frame beam is instable and difficult to design or construction efficiency is low due to the fact that a connection bracket is protruded and the like. The connection node of the steel rib and the steel frame beam comprises the steel rib located in concrete, the steel frame beam located outside the concrete and an end plate arranged on the steel rib. The front face of the end plate is exposed to the outside of the concrete and does not protrude out of the concrete. The steel frame beam is connected onto the front face of the end plate. The connection node avoids interference between the steel rib and the steel frame beam, and has the advantages of being stable in structure, convenient to transport and enabling steel bars in the concrete to pass conveniently. The front face of the end plate does not protrude out of the concrete, so that the connection node is simple in connection, facilitates concrete slip-form construction and is low in engineering cost.
