Abstract
The invention discloses a beam-column connection node and method for a combined wall-column cold-shaping steel structure. The connection node includes a steel sleeve tube, an upper node plate, a lower node plate and a splicing part, the steel sleeve tube is embedded in the ends of adjacent upper and lower square-steel-tube concrete columns and is fixedly connected with the upper node plate, the lower node plate and the splicing part which are arranged at the same side of the square-steel-tube concrete columns, the splicing part, an ALC floor plate and the flange of an H-shaped beam are fixedly connected with the upper and lower node plates through a connection screw rod and a connection screw bolt, and after node connection is completed, post-grouting is conducted on the steel sleeve tube. By adoption of the connection node, it is ensured that upper and lower layers of the cold-shaping steel structure are effectively connected, at the same time, the purpose is achieved that the structure can be subjected to stratified splicing, forming of a room modularization prefabrication technology is facilitated, the construction difficulty is reduced, the square-steel-tube concrete columns, internal wall elements and the floor plate are mutually tied and connected through cross tie rods and the node plates, and the integrality of the structure is further improved. Meanwhile, construction is convenient by the adoption of the connection method.
Description
technical field [0001] The invention relates to a building structure, in particular to a beam-column connection node and a connection method for a composite wall-column cold-formed steel structure. Background technique [0002] Due to the large population, tight land resources, and severe earthquake disasters, it is more in line with my country's national conditions to develop energy-saving, environmentally friendly, and highly industrialized cold-formed steel structures from low-rise to multi-layer. It is also an effective way to accelerate the industrialization and prefabrication of housing. However, the existing low-rise cold-formed steel structure cannot be directly applied to multi-storey residential buildings. At present, there is an urgent need to solve technical problems such as more stringent structural vertical load-bearing, shear resistance, and overturning resistance brought about by the development of cold-formed steel structures from low-rise to multi-storey. ....
