Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a connection node between a rigid column and a steel beam. Background Art

[0002] A rigid column is a structural form that combines the advantages of steel and concrete, offering high load-bearing capacity and excellent seismic resistance. Steel beams are key components of steel structures, responsible for bearing and transmitting horizontal loads. The connection between rigid columns and steel beams is a crucial component of building structures, and their connection directly impacts the stability and load-bearing capacity of the entire structure. Therefore, the connection between rigid columns and steel beams must possess sufficient strength and rigidity to ensure the overall performance of the structure.

[0003] When existing steel beams are connected to rigid columns, they are mostly fixed to the rigid columns by bolts. Not only do corresponding screw holes need to be opened on the rigid columns, which affects the performance of the rigid columns, but the connection part is only connected by bolts, which will also lead to relatively general structural stability and bearing capacity of the connection nodes. Utility Model Content

[0004] The main purpose of the utility model is to provide a connection node between a rigid column and a steel beam, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A connection node between a rigid column and a steel beam comprises a steel section with a concrete outer layer installed on the outer surface of the steel section, support devices installed on the left and right ends of the steel section, and an I-shaped steel beam fixedly installed on the opposite ends of the two support devices.

[0007] Preferably, a No. 2 connecting frame is welded to the left end of the steel section, and a No. 1 connecting frame is welded to the right end of the steel section. A set of reinforcing steel bars are installed on the upper and lower ends of the No. 1 and No. 2 connecting frames, and both sets of reinforcing steel bars are inserted and fixed on the steel section. When it is necessary to connect with an I-shaped steel beam, the I-shaped steel beam is aligned with the slot in the No. 1 connecting frame and inserted, and then the fixing bolts are screwed into the bolt holes to complete the installation of the I-shaped steel beam. Similarly, the No. 2 connecting frame is installed in the same way. By docking the connecting frame with the I-shaped steel beam, it is avoided to open screw holes on the steel section, thereby improving the support stability of the steel section.

[0008] Preferably, the support device includes two mounting steel plates, two of which are provided with a set of fixing bolts installed at the front ends of the two mounting steel plates. Auxiliary support blocks are installed at the upper and lower ends of the two mounting steel plates. The corresponding ends of the auxiliary support blocks are each provided with an opening. The two mounting steel plates are welded to the front and rear ends of the No. 1 connecting frame, respectively. After the mounting steel plates are welded and installed, they can not only support the front and rear parts of the I-shaped steel beam, but also the auxiliary support blocks are made of the same material as the mounting steel plates. When the auxiliary support blocks are then welded to the mounting steel plates, one side of the auxiliary support blocks is in close contact with the outer layer of concrete, and the other side is in close contact with the connecting frame through the opening, thereby further supporting the connecting frame.

[0009] Preferably, a group of bolt holes are opened at the front end of the I-shaped steel beam.

[0010] Preferably, the material of the No. 1 connecting frame and the No. 2 connecting frame is consistent with the steel section, and the No. 1 connecting frame and the No. 2 connecting frame are both U-shaped.

[0011] Preferably, the fixing bolt and the bolt hole are of the same model and have corresponding positions front to back.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Connecting frame No. 1 and connecting frame No. 2 are welded on the right and left ends of the steel respectively, and the materials of connecting frame No. 1 and connecting frame No. 2 are consistent with the steel. In addition, the two mounting steel plates on the supporting device are welded to the front and rear ends of connecting frame No. 1 respectively. When it is necessary to connect with the I-shaped steel beam, align the I-shaped steel beam with the slot in connecting frame No. 1 and insert it. Then screw the fixing bolts into the bolt holes to complete the installation of the I-shaped steel beam. Similarly, connecting frame No. 2 is installed in the same way. By docking the connecting frame with the I-shaped steel beam, screw holes are avoided on the steel, thereby improving the support stability of the steel.

[0014] 2. Two groups of reinforcing steel bars are fixedly installed on the steel section. The two groups of reinforcing steel bars are respectively installed on the upper and lower ends of the No. 1 connecting frame and the No. 2 connecting frame, thereby improving the supporting performance of the No. 1 connecting frame and the No. 2 connecting frame. At the same time, after the installation steel plate is welded and installed, it can not only support the front and rear parts of the I-shaped steel beam, but also the material of the auxiliary support block is consistent with the installation steel plate. The auxiliary support block is then welded to the installation steel plate. At this time, one side of the auxiliary support block is in close contact with the outer layer of concrete, and the other side is in close contact with the connecting frame through the opening, thereby further supporting the connecting frame.

In addition, the two mounting steel plates 20 on the supporting device 2 are welded to the front and rear ends of the No. 1 connection frame 10 respectively. When it is necessary to connect with the I-shaped steel beam 3, the I-shaped steel beam 3 is aligned with the slot in the No. 1 connection frame 10 and inserted therewith, and then the fixing bolts 21 are screwed into the bolt holes 30 to complete the installation of the I-shaped steel beam 3. Similarly, the No. 2 connection frame 11 is also installed in the same way, and is docked with the I-shaped steel beam 3 through the connection frame to avoid Screw holes are opened on the steel section 1 to improve the supporting stability of the steel section 1, and two groups of reinforcing steel bars 12 are inserted and fixed on the steel section 1. The two groups of reinforcing steel bars 12 are respectively inserted and installed at the upper and lower ends of the No. 1 connecting frame 10 and the No. 2 connecting frame 11, thereby improving the supporting performance of the No. 1 connecting frame 10 and the No. 2 connecting frame 11. At the same time, after the mounting steel plate 20 is welded and installed, it can not only support the front and rear parts of the I-shaped steel beam 3, but also the material of the auxiliary support block 22 is consistent with the mounting steel plate 20. The auxiliary support block 22 is then welded to the mounting steel plate 20.
