Description
Technical Field
The utility model relates to a shaped steel concrete beam column nodal connection structure.
Background
When a super high-rise structure is designed, structural seismic ductility is increased for controlling the section sizes of beams, columns and shear walls, and a formed steel concrete structure is designed by arranging section steel in frame beams, frame columns and shear walls. The structural steel concrete frame column and the shear wall are internally provided with the large-size structural steel, and the steel bars in the structural steel beams connected with the structural steel concrete frame column and the shear wall can not be effectively anchored on the structural steel columns and the structural steel shear wall, so that the construction process is difficult and heavy, if the construction process is not proper, the construction progress is influenced, the bearing capacity of the structural steel is even reduced, and potential safety hazards are brought to the structure. If the steel bars in the section steel beam are effectively anchored on the section steel concrete column and the section steel concrete shear wall, the conventional method comprises the following steps: 1. direct perforation method: and (3) carrying out factory punching on the section steel in the section steel concrete column and the section steel concrete shear wall, and then punching the reinforcing steel bars. The technical defect is that the mechanical property of the section steel is weakened, the section steel is reinforced when the specification requirement is not met, secondary drilling and other problems can be caused if lofting deviation exists on the site, the construction is troublesome, and the operability is poor. 2. Avoidance method: and properly adjusting the position of the section steel or bending the reinforcing steel bars to obtain a mutually-avoided space between the section steel and the reinforcing steel bars. The method has the disadvantages that the positions of the profile steel and the bending angle of the steel bar are limited, the method is only adopted when the positions of the profile steel and the steel bar are slightly deviated, the application range is small, and the method can not be basically used when the profile steel with the larger diameter of the steel bar has a larger size. 3. And (3) a conventional gusset plate welding method: and welding steel node plates on the inner section steel flanges of the section steel concrete columns and the section steel concrete shear walls, and then welding the steel bars in the section steel concrete beams with the node plates. The technical defect is that the welding space is small due to the fact that the section steel beam protective layer is small, only one row of steel bars can be welded on the spot, welding quality is difficult to guarantee, and the welding method cannot be achieved when multiple rows of steel bars exist. If the built-in section steel can be designed into the variable cross-section reinforced section steel at the end part of the section steel beam through a certain structural measure, the bearing capacity of the section steel after the variable cross-section of the beam end is reinforced is larger than that of a combined beam consisting of the section steel in the middle of the beam and the steel bars, and the steel bars in the section steel reinforced concrete beam in the middle of the beam can be welded on the section steel in the section steel reinforced concrete beam at the beam end. Under the special structure, the structure safety is ensured, the construction difficulty is greatly reduced, and the construction cost is reduced.
