Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

"First", "second" and similar words used in the present invention do not indicate any order, quantity or importance. "Connected" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly. The embodiment of the present application discloses a connection node between a rigid column and a steel beam having a strip steel plate hoop.

[0030] The core of the utility model is to provide a connection node between a rigid column and a steel beam with a strip steel plate hoop.

[0031] Please refer to Figures 1 to 3 . The stiff column and steel beam connection node with strip steel plate hoops provided by the utility model includes a steel frame column, a corbel web 7 and a steel plate hoop 4, and the two ends of the corbel web 7 are respectively welded with a corbel upper wing plate 5 and a corbel lower wing plate 6. There are several corbel webs 7 in total, and they are arranged circumferentially between the corbel upper wing plate 5 and the corbel lower wing plate 6. The steel frame column includes an upper steel frame column 1, a lower steel frame column 2 and a node domain steel frame column 3. The upper steel frame column 1 is welded to the side of the corbel upper wing plate 5 away from the corbel web 7, the lower steel frame column 2 is welded to the side of the corbel lower wing plate 6 away from the corbel web 7, and the node domain steel frame column 3 is welded between the corbel upper wing plate 5 and the corbel lower wing plate 6. Stiffening ribs 11 are welded on both sides of each corbel web 7, and a plurality of steel plate hoops 4 with intervals between each two adjacent corbel webs 7 are arranged, and the two ends of each steel plate hoop 4 are respectively welded to two adjacent stiffening ribs 11.

[0032] The present application connects the steel plate hoops 4 between the corbel webs 7, which replaces the steel column stirrups, making the force transmission between the rigid column and the steel beam more uniform and reliable, effectively improving the bearing capacity, rigidity and seismic performance of the structure, and ensuring the safety of the building structure under various loads. The steel plate hoops 4 are broken into multiple pieces and set between every two corbel webs 7, which reduces the workload of on-site welding and perforation. The steel plate hoops 4 can be prefabricated in the factory, improving construction efficiency. At the same time, within the same area (between two adjacent corbel webs 7), a certain distance is retained between each two steel plate hoops 4. Compared with the way that the steel plate hoops 4 in the same area are integrated, this setting can make the concrete pouring more compact.

[0033] The aforementioned steel strip hoops are used to connect the rigid columns and beams using multiple disconnected steel strip hoops 4. These hoops can be prefabricated in a factory and quickly installed on site, reducing on-site welding and punching workload and improving construction efficiency. Furthermore, spacing between the steel strip hoops 4 within the same area allows for a more compact concrete pour, improving overall construction quality.

[0034] The following is a more detailed introduction to the connection node between the rigid column and the steel beam with the strip steel plate hoop provided by the present invention in conjunction with the accompanying drawings and specific embodiments.

[0035] It should be noted that the upper steel column 1 includes an upper steel column web 102 and an upper steel column flange 101 welded to the end of the upper steel column web 102, and the lower steel column 2 includes a lower steel column web 202 and a lower steel column flange 201 welded to the end of the lower steel column web 202 (this part is a conventional setting in the prior art and will not be repeated here).

[0036] In a specific embodiment, reference Figure 1 and Figure 2 The steel plate hoop 4 is a strip-shaped arc-shaped steel plate hoop, and the stiffening rib 11 is an arc-shaped rib.

[0037] Stiffening ribs 11 are vertically arranged on both sides of the corbel web 7 between each corbel upper wing 5 and each corbel lower wing 6. The use of curved ribs for these stiffening ribs 11 facilitates the installation of the steel plate hoops 4. Multiple strip-shaped curved steel plate hoops 4 are horizontally welded between two adjacent stiffening ribs 11. During the welding process, the strip-shaped curved steel plate hoops 4 and the curved stiffening ribs 11 can better fit together, reducing gaps caused by shape mismatches, thereby enhancing the overall stability of the node. At the same time, the curved design allows the steel plate hoops to distribute force more evenly when subjected to stress, avoiding stress concentration and improving the bearing capacity and durability of the node.

[0038] Based on any of the above embodiments, Figure 3 The steel plate hoop 4 is a strip L-shaped steel plate hoop, and the stiffening rib 11 is a vertical rib.

[0039] Compared to the aforementioned curved steel plate hoops 4 and curved stiffening ribs 11, the L-shaped steel plate hoops provide a stronger lateral support force. When subjected to forces from all directions, the L-shaped steel plate hoops can more effectively disperse stress and prevent structural damage caused by uneven loads or external impacts.

[0040] Optionally, the steel plate hoop 4 can be made of high-strength steel, which has good corrosion resistance and fatigue resistance. Compared with traditional concrete stirrups, it can maintain the stability and reliability of the connection node during long-term use.

[0041] Based on any of the above embodiments, Figure 1 and Figure 2 The upper steel column 1 and the lower steel column 2 are both welded with a first steel bar connector 8, and the first steel bar connector 8 is used to weld the longitudinal reinforcement of the beam.

[0042] Specifically, the first steel bar connector 8 is provided on the upper steel column flange 101 and the lower steel column flange 201 to facilitate welding of the longitudinal reinforcement of the beam. The first steel bar connector 8 is a flat plate structure, and the longitudinal reinforcement of the beam is directly welded to the horizontal surface of the first steel bar connector 8. The above-mentioned first steel bar connector 8 is suitable for the case where the beam is a steel beam. If the beam is a pure steel beam, the first steel bar connector 8 can be omitted.

[0043] Based on any of the above embodiments, Figure 1 and Figure 2 The width of the first steel bar connector 8 is consistent with the width of the flange plates of the upper steel frame column 1 and the lower steel frame column 2.

[0044] Specifically, the width of the first rebar connector 8 is consistent with the width of the upper and lower steel column flanges 101, 201. This configuration allows the first rebar connector 8 to fit more closely to the upper and lower steel column flanges 101, 201, reducing gaps caused by size mismatches. This tight fit helps enhance the stability of the connection and prevents loosening or slippage caused by external forces. Preferably, the length of the first rebar connector 8 can be set to 5d + 10 mm, where d is the diameter of the beam longitudinal bar.

[0045] Based on any of the above embodiments, Figure 1 and Figure 2 A stiffening plate 10 is provided on the side of the upper steel frame column 1 and the lower steel frame column 2 away from the first steel bar connector 8.

[0046] Specifically, the stiffening plate 10 is located at the elevation of the first steel connector 8. The stiffening plate 10 is a triangular plate. The stiffening plate 10 is welded between the upper steel column flange 101 and the upper steel column web 102, and between the lower steel column flange 201 and the lower steel column web 202. The stiffening plate 10 can effectively improve the stability of the connection. The use of the triangular stiffening plate 10 simplifies the node area. Compared with a solid stiffening plate, the triangular stiffening plate 10 has a smaller collision area and can better ensure that the concrete in the node area is poured densely. Optionally, the thickness of the stiffening plate 10 is the same as that of the first steel connector 8.

[0047] Based on any of the above embodiments, Figure 1 and Figure 2A second steel bar connector 9 is welded on both the upper wing plate 5 and the lower wing plate 6 of the corbel. The second steel bar connector 9 is used to threadably fix the column longitudinal reinforcement.

[0048] Specifically, the second steel bar connector 9 is provided between the upper corbel wing plate 5 and the lower corbel wing plate 6. The second steel bar connector 9 is used to threadably connect the column longitudinal reinforcement, facilitating the installation of the column longitudinal reinforcement. Optionally, the second steel bar connector 9 and the stiffening rib 11 are located on the same vertical level, and the horizontal positioning of the second steel bar connector 9 is consistent with that of the stiffening rib 11.

[0049] Based on any of the above embodiments, Figure 1 and Figure 2 The upper wing plate 5 of the corbel is an integrally formed plate body, which interrupts the upper steel column 1 and the node domain steel column 3 on both sides of the upper wing plate 5. The lower wing plate 6 of the corbel is an integrally formed plate body, which interrupts the lower steel column 2 and the node domain steel column 3 on both sides of the lower wing plate 6.

[0050] Specifically, the upper wing plate 5 of the corbel and the lower wing plate 6 of the corbel break the steel frame column into the upper steel frame column 1, the lower steel frame column 2 and the node domain steel frame column 3. The upper wing plate 5 of the corbel and the lower wing plate 6 of the corbel pass through the steel frame column. The upper wing plate 5 of the corbel and the lower wing plate 6 of the corbel as a whole plate can transmit force to the steel beam flange more directly, and are more suitable for situations where the thickness of the steel beam flange is thicker.

[0051] Optionally, grouting holes are provided on the upper wing plate 5 of the corbel and the lower wing plate 6 of the corbel. The provision of the grouting holes effectively improves the density of concrete pouring in the node area.

[0052] Based on any of the above embodiments, Figure 1 and Figure 2 The corbel web 7 is connected to the steel beam with high-strength bolts 12, and the corbel upper wing plate 5 and the corbel lower wing plate 6 are welded and fixed to the steel beam flange.

[0053] The above describes in detail the connection node between a rigid column and a steel beam provided by the present invention, which has a strip steel plate hoop. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that for ordinary technicians in this technical field, various improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
