Abstract

A node structure for combined beam and concrete column is composed of the concrete in the core region of node, steel-plate hoop, extended plate, long screw bolt, and the negative reinforcement of combined beam. Its construction method includes such steps as calculating the stress of node, and the number and diameter of long screw bolts, determining the sizes of extended plate and steel-plate hoop and making them, welding the extended plates with I-shaped beam, installing all members, pouring concrete, and turning the long screw bolts for closing the extended plate to steel-plate hoop.

Description

technical field [0001] The invention relates to the field of structural engineering in civil engineering, in particular to a joint structure of composite beams and concrete columns and a construction method thereof. Background technique [0002] Steel and concrete composite beams can give full play to the strengths of steel and concrete. Our country began to study the composite beam structure in the early 1950s, and then it has been widely used in highway and railway bridges. The use of composite beams in housing construction is more economical than the use of concrete beams. During the use of composite beams, the overall stability of the beams can be ignored, and the advantages of steel and concrete can be fully utilized. It can save materials, reduce the weight of the floor, and reduce the beam height. , Enhance rigidity and bearing capacity. [0003] Compared with the general concrete structure system, the structural system composed of reinforc...
