Description
Technical Field
The utility model relates to a building frame component technical field specifically is a concrete column and H shaped steel roof beam composite node structure.
Background
The joint is an important component for connecting the frame beam and the frame column, can effectively transfer bending moment and shearing force of the beam end, has important influence on the structure, and the connecting part has enough bearing capacity, rigidity and ductility. In the design of the steel structure, the connection mode between the steel structure and the concrete structure is a very important problem, the processing and installation of the connection are complex and labor-consuming, and therefore, a proper connection scheme and a node construction are needed to be selected. Nowadays, the types of steel structure beam column node mainly include welding, rivet connection, bolted connection, and welded connection is the most common connection method of steel construction, and the advantage is: the steel does not need to be punched, so that the engineering quantity and time are saved, and meanwhile, the sectional area of the material is not damaged; the cross section of the component is flexibly connected, the structure is simple, and components in any shape can be directly connected without auxiliary parts; the welding compactness is relatively good, the structural rigidity is high, and the integrity is good. The disadvantages are that: welding at high temperature to make the material property of the welding part become brittle; the existence of welding residual stress and residual deformation reduces the bearing capacity of the component; in the process of structural seismic resistance, local cracks are easy to generate at welding positions and easily extend to the whole. The connection of the heavy-duty working crane beam, the column and the brake beam and the node connection of the truss bridge are not suitable to adopt welding.

The bolted connection comprises common bolted connection and high-strength bolted connection, wherein the common bolted connection has the advantages of simple construction and convenient installation and disassembly. The disadvantage is the large amount of steel used. The structure is suitable for installation and connection and frequent disassembly and assembly. The high-strength bolt connection has the advantages of steel consumption saving, tight connection, convenient installation, good stress performance, detachability, difficult looseness under the action of dynamic load and the like. Since the high-strength bolt connection includes the advantages of the rivet connection and the general bolt connection, a popularization trend is gradually exhibited.
