Description

H-shaped steel and steel-reinforced concrete column hinged connection node

technical field

The utility model relates to the technical field of construction engineering, in particular to a hinged connection node of an H-shaped steel and a steel-reinforced concrete column.

Background technique

It is well known that in a super high-rise steel structure building, due to the large number of floors and the large load, the columns are subjected to a large axial force and a large bending moment. It is difficult to use a single concrete column or a single steel column to meet the stress requirements. Most of the super high-rise columns are steel-reinforced concrete columns. At present, in the conventional joints of super high-rise steel structure steel beams and steel reinforced concrete columns, due to the influence of steel reinforced concrete, rigid joints and hinged joints cannot adopt column flange welding connection plates and steel beam bolt welding rigid joints and bolt hinges The connected nodes are usually hinged nodes using pre-embedded steel plates in concrete and steel beams, but the pre-embedded panels are easily affected by the pouring concrete, which causes deviations in the embedding of the pre-embedded panels, and the accuracy is difficult to control.

SUMMARY OF THE INVENTION

In order to overcome the deficiencies in the background technology, the utility model discloses a hinged connection node between an H-shaped steel and a steel-reinforced concrete column.

In order to achieve the purpose of the invention, the utility model adopts the following technical solutions:

An H-shaped steel and a steel-reinforced concrete column are hingedly connected, comprising the H-shaped steel and a steel-reinforced concrete column with a cross-shaped cross-section; One end of the H-shaped steel is fixedly connected to the outside of any steel column flange plate of the reinforced concrete column through a steel corbel, and a plurality of studs are arranged on the surface of the upper and lower flange plates and the web plate of the steel corbel. The connecting plate of the leg is arranged in the space between the upper and lower wing plates of the H-shaped steel, and the connecting plate of the steel corbel is provided with multiple rows and multiple columns of oblong holes evenly spaced, and high-strength bolts and H Steel connection.

The H-shaped steel is hingedly connected to the reinforced concrete column, and the upper and lower flange plates of the steel corbel and the edges of the web are welded and connected to the outside of the steel column flange plate of the reinforced concrete column.

The H-shaped steel and the steel-reinforced concrete column are hingedly connected, and the connection between the H-shaped steel and the oblong hole on the steel corbel connecting plate is correspondingly provided with multiple rows and columns of circular holes, and the diameter of the circular holes is 2mm larger than the diameter of the high-strength bolts.

Owing to adopting the above-mentioned technical scheme, the utility model has the following beneficial effects:

The hinged connection node between the H-shaped steel and the steel-reinforced concrete column of the utility model is provided with a tie plate between two adjacent steel column flange plates, which enhances the overall stability and local joint stiffness; The upper and lower flange plates and the surface of the web are provided with multiple studs, which effectively increase the connection area of the surface concrete layer, increase the shear strength of the contact surface, and make the steel corbel and the concrete surface firmly combine and bear the force together. The oblong hole can partially release the bending moment, thereby reducing the damage to the concrete column; the utility model has the advantages of simple structure and convenient installation, and ensures the feasibility and safety of connecting nodes.

Detailed ways

The present utility model can be explained in detail through the following examples, and the purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model.

Combined with Figure 1 H-shaped steel and reinforced concrete column hinged connection node, including H-shaped steel 6 and steel reinforced concrete column 1 with a cross-shaped section, the steel reinforced concrete column 1 is between two adjacent steel column flange plates. A trim plate 2 is provided, and one end of the H-shaped steel 6 is fixedly connected to the outside of any one of the steel column flange plates of the steel reinforced concrete column 1 through the steel corbel 3. The upper and lower flange plates and the surface of the web plate of the steel corbel 3 All are provided with a plurality of pegs 4, the connecting plate of the steel corbel 3 is arranged in the space on one side between the upper and lower wing plates of the H-shaped steel 6, and the connecting plate of the steel corbel 3 is evenly spaced with multiple rows and multiple columns. The oblong holes 5 are all provided with high-strength bolts in the oblong holes 5 to be connected with the H-shaped steel 6 .

The H-shaped steel and the steel reinforced concrete column are hinged connection nodes, and the upper and lower flange plates of the steel corbel 3 and the edges of the web are connected to the outside of the steel column flange plate of the steel reinforced concrete column 1 by welding.

The H-shaped steel and the steel reinforced concrete column are hingedly connected, and the connection between the H-shaped steel 6 and the long circular hole 5 on the connecting plate of the steel corbel 3 is correspondingly provided with multiple rows and multiple columns of circular holes, and the diameter of the circular holes is larger than that of the high-strength bolts. 2mm.

To implement the hinged connection node between the H-shaped steel and the steel reinforced concrete column according to the present invention, during installation, the studs 4 are welded on the upper and lower flange plates and the web surface of the steel corbel 3, and the steel corbel 3 is connected to the steel reinforced concrete. The exterior of the column 1 steel column flange plate is welded and processed in the workshop, and no post-embedded steel plate is required, and the concrete pouring will not cause disturbance to the steel corbel 3 connecting plate, which ensures the installation accuracy, and the steel corbel 3 is connected at the same time. The long round holes in the plate are hinged and fixed with high-strength bolts first, and when the deformation is over, fillet welds are used to surround the steel corbel 3 connection plate and H-beam to ensure the feasibility and safety of the connection.

The part not described in detail in this utility model is the prior art.
