Joint adaptor for connecting reinforced concrete column and steel beams and connecting structure of reinforced concrete column and steel beams

Abstract

The invention provides a joint adaptor for connecting a reinforced concrete column and steel beams. The joint adaptor for connecting the reinforced concrete column and the steel beams comprises optimal joint lower flanges and optimal joint upper flanges; and the optimal joint lower flanges are located below the optimal joint upper flanges. When the joint adaptor is connected with the steel beams,the lower flanges are not arranged at the ends of the steel beams within a certain range from the side of the column, webs are placed on lower flange plates corresponding to optimal joints during hoisting, the webs extend into the edge of the concrete column for a certain distance, the webs are field welded to the optimal joint lower flanges, and the lower flanges of the steel beams are equally welded to the lower flanges of the optimal joints; the upper flanges of the steel beams are equally welded to the upper flanges of the optimal joints; and openings are reserved in corresponding positions of the webs of the steel beams and column hooping and used for hooping penetrating and binding at site, 135 degrees inclined hook or 90 degrees straight hook welding can be adopted, peripheral closed hooping is formed, and binding hooping can be used in internal hooping.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a node adapter used for connecting reinforced concrete columns and steel beams and a connection structure thereof. Background technique [0002] In the building structure, traditional concrete columns are connected with steel beams, and a node conversion part is designed, which is generally a core component of the node domain as a whole, and a part protrudes out of the column, and is connected to the steel beam with bolts. This method is complicated to process and consumes a large amount of steel. Since the spacing between longitudinal bars of concrete columns is generally about 200 mm, the width of the flange of the steel beam is often greater than the spacing of longitudinal bars. It is difficult for the node domain to directly penetrate the reinforced concrete column. The problem of fighting between bars and steel beams, long construction process and lo...

Problems solved by technology

This method is complicated to process and consumes a large amount of steel. Since the spacing between longitudinal bars of concrete columns is generally about 200 mm, the width of the flange of the steel beam is often greater than the spacing of longitudinal bars. It is difficult for the node domain to directly penetrate the reinforced concrete column. The problem of fighting between bars and steel beams, long construction process and low efficiency; the more common method is to use concrete columns to hold square steel plate buckets, and the steel plates are divided into grids in the bucket, and the longitudinal steel bars pass through the grids, and the steel beams connect the end plates and The high-strength bolts are connected to the outer wall of the square steel drum, or the cross gusset plate is embedded in the concrete, the outside is connected by bolts, and the upper and lower flanges are connected by steel bars or steel plates. The above schemes are either more complicated and difficult to construct. , or the cost of structural steel plates is high and the connecting plates and steel beams rely on high-strength bolts to resist shearing, and the shear force between beams and steel beams is almost entirely borne by high-strength bolts. After a long time, the bolts are corroded and weakened, making it impossible to repair
