Description
Technical Field
The utility model relates to a building house column base field especially relates to an outer packet mode column base structure of concrete.
Background
Along with the rapid development of economy, synthesize national force and strengthen day by day, the steel industry makes huge progress on this basis, and the output of steel then increases more year by year, because the steel construction has advantages such as light weight high strength, plasticity toughness are good, repeatedly usable, but has relevant researcher investigation and shows, because most of designers pay attention to superstructure or the atress performance of component, lead to a large amount of steel construction building to produce the destruction at column base node, so the utility model discloses will release a practical concrete outer cladding column base.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide an outer packet of column base structure of concrete, most moment of flexure and shear force can be undertaken through the inside and outside package concrete of column base to this outer packet of column base, and the bottom plate then directly passes the concrete foundation of lower part with the axle pressure, with the cohesive force between steel column and outsourcing concrete, the anti shear capacity of peg resists the internal force transmission and the restoring force characteristic of pulling force to outsourcing formula column base, and the steel column can also play shock-resistant effect moreover.
In order to achieve the above object, the utility model adopts the following technical scheme: a concrete wrapped column base structure: comprises a steel column, a horizontal stiffening rib, a stud, outer concrete, a bottom plate, an anchor bolt and a foundation beam; the foundation beam is of a reinforced concrete structure, and reinforcing steel bars are alternately embedded in the foundation beam in a horizontal and vertical manner; the reinforcing steel bars in the middle of the foundation beam are respectively connected with the horizontal stiffening ribs through binding and welding, and anchor bolts are embedded in the center of the foundation beam; one half of the horizontal stiffening rib is embedded in the foundation beam, and the other half of the horizontal stiffening rib vertically extends upwards for a certain distance; reinforcing steel bars on two sides of the top end of the horizontal stiffening rib are bent inwards to form small hooks, and the inner side of the top of the horizontal stiffening rib is connected with the steel column through studs; the anchor bolt is of a cylindrical steel structure, and the bottom of the anchor bolt is embedded in the foundation beam; the foundation beam is connected with the bottom plate through anchor bolts; the bottom plate is of a plate-shaped steel structure, and the ground of the bottom plate is attached to the foundation beam; the two sides of the top end of the bottom plate are connected with the steel column through welding; the steel column is of a cylindrical steel structure, the bottom of the steel column, the horizontal stiffening ribs and the studs form a steel frame respectively, and the steel frame is filled with outer concrete to form a connecting column point; the top of the steel column penetrates through the outer-coated concrete to extend upwards, and the outer-coated concrete is poured into a cylindrical shape.
Preferably, the peg has a diameter in the range 16mm to 18 mm.
Preferably, the necessary distance from the stud to the edge of the steel column sheet is less than 100 mm.
The utility model has the advantages that: the concrete wrapped column base can bear most of bending moment and shearing force through concrete wrapped inside and outside the column base, the bottom plate directly transmits the axial pressure to the concrete foundation of the lower part, the internal force transmission and restoring force characteristics of the pulling force on the wrapped column base are resisted by the adhesive force between the steel column and the wrapped concrete and the shearing resistance bearing force of the stud, and the steel column can also play a role in resisting shock.
