Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a connection node between a concrete column and an H-shaped steel beam. Background Technology

[0002] The connection node between the concrete column and the H-beam is a key part of the collaborative work between the steel structure and the concrete structure, and its background technology involves a variety of connection forms and optimization strategies.

[0003] Traditional nodes often use welding, bolting, or a combination of these methods, but these methods have problems such as high construction difficulty and defects in load-bearing performance.

[0004] The existing connection nodes between concrete columns and H-beams are simply connected by fixing bolts, without addressing the downward pressure exerted on the connection points by the H-beams as horizontal suspension beams. This results in the pressure at the top of the connection point being greater than that at the bottom, leading to an imbalance in the pressure and compromised seismic resistance. Utility Model Content

[0005] The purpose of this invention is to provide a connection node between a concrete column and an H-beam to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connection node between a concrete column and an H-beam, comprising a bearing plate, stiffening plates on both sides of the top of the bearing plate, a connecting block on the top of the bearing plate, a bearing column on one side of the bearing plate, a connecting plate fixedly mounted on the bearing plate, and an H-beam fixedly connected to the connecting plate.

[0007] As a further description of the above technical solution: the bearing plate, the connecting block and the stiffening plate are integrally formed.

[0008] As a further description of the above technical solution: a fixing bolt is provided between the connecting block, the bearing plate and the bearing column.

[0009] As a further description of the above technical solution: the end of the fixing bolt away from the bearing column is square.

[0010] As a further description of the above technical solution: the stiffener is configured in a triangular shape, with the longest side of the stiffener being a long arc.

[0011] As a further description of the above technical solution: the bottom of the connecting block is set as a slope.

[0012] As a further description of the above technical solution: a support plate is provided at the bottom of the H-steel, and a support rod is fixedly connected to the bottom of the support plate, and the support rod is connected to the bottom of the bearing plate.

[0013] As a further description of the above technical solution: bolts are provided between the support plate, the connecting plate and the H-beam.

[0014] This utility model provides a connection node between a concrete column and an H-beam. It offers the following advantages: This structure uses a bearing plate to fix the H-beam onto the bearing column. Compared to traditional installation methods, this structure strengthens the bearing plate itself and the connection between the bearing plate and the bearing column through stiffening plates and connecting blocks. The inclined bottom of the connecting block, combined with fixing bolts, connects the connecting block to the bearing column. The inclined bottom of the connecting block allows the bearing column and fixing bolts to exert an upward tensile force on the bearing plate, counteracting the downward force exerted by the H-beam on the top of the bearing plate, thus increasing the structural strength of the connection point. Simultaneously, the stiffening plates on both sides reinforce the bearing plate, enhancing its bending resistance.

[0015] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0016] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4A connection node between a concrete column and an H-beam includes a bearing plate 1, stiffening plates 2 on both sides of the top of the bearing plate 1, a connecting block 3 on the top of the bearing plate 1, a bearing column 4 on one side of the bearing plate 1, a connecting plate 5 fixedly mounted on the bearing plate 1, and an H-beam 6 fixedly connected to the connecting plate 5. This structure uses the bearing plate 1 to fix the H-beam 6 onto the bearing column 4. Compared to traditional installation methods, this structure strengthens the bearing plate 1 body and the connection between the bearing plate 1 and the bearing column 4 through the stiffening plates 2 and the connecting block 3. The connecting block 3 is inclined at the bottom, and a fixing bolt 7 connects the connecting block 3 to the bearing column 4. The inclined bottom of the connecting block 3 allows the bearing column 4 and the fixing bolt 7 to exert an upward tension on the bearing plate 1, counteracting the downward force exerted by the H-beam 6 on the top of the bearing plate 1, thus increasing the structural strength of the connection point. Simultaneously, the stiffening plates 2 on both sides reinforce the bearing plate 1 body, enhancing its bending resistance.

[0021] As a preferred technical solution in this embodiment, the bearing plate 1, the connecting block 3, and the stiffening plate 2 are integrally formed; by integrally forming the bearing plate 1, the connecting block 3, and the stiffening plate 2, the structural strength of the connector itself is increased, thereby improving the connection capability of the connector.

[0022] As a preferred technical solution of this embodiment, a fixing bolt 7 is provided between the connecting block 3, the bearing plate 1 and the bearing column 4; before fixing the H steel 6 to the bearing column 4, holes need to be drilled in the bearing column 4, and then chemical test tubes are placed into the drilled holes. Then, the fixing bolt 7 is spirally rotated into these holes. In this application, the fixing bolt 7 is a chemical bolt 10. The chemical test tubes enter the holes and react with each other, firmly fixing the fixing bolt 7 inside the bearing column 4. The bearing plate 1 and the connecting plate 5 are then installed onto the bearing column 4 through the fixing bolt 7.

[0023] As a preferred technical solution in this embodiment, the end of the fixing bolt 7 away from the bearing column 4 is set in a square shape; by setting one end of the fixing bolt 7 in a square shape, it is convenient to rotate the fixing bolt 7 mechanically.

[0024] As a preferred technical solution in this embodiment, the stiffener 2 is configured in a triangular shape, with the longest side of the stiffener 2 being a long arc; the farthest point of the stiffener 2 from the bearing plate 1 is located at the top of the stiffener 2, and the closest point is located at the bottom of the stiffener 2, which can effectively improve the bending resistance of the bearing plate 1 and can transfer the force on the top of the bearing plate 1 to the bottom of the stiffener 2, thereby improving the overall bending resistance.

[0025] As a preferred technical solution in this embodiment, the bottom of the connecting block 3 is set as an inclined surface; by setting the bottom of the connecting block 3 as an inclined surface, the fixing bolt 7 can apply an upward force to the connecting block 3 to resist the downward force exerted by the H steel 6 on the top of the bearing plate 1.

[0026] As a preferred technical solution in this embodiment, a support plate 8 is provided at the bottom of the H-steel 6, and a support rod 9 is fixedly connected to the bottom of the support plate 8. The support rod 9 is connected to the bottom of the bearing plate 1. One end of the support rod 9 is welded to the bearing plate 1, and the other end is welded to the support plate 8, forming a triangular support between the bottom of the bearing plate 1 and the H-steel 6, making the H-steel 6 more stable to install.

[0027] As a preferred technical solution in this embodiment, bolts 10 are provided between the support plate 8, the connecting plate 5 and the H-steel 6; the connecting plate 5 and the support plate 8 are respectively connected to the H-steel 6 by the bolts 10.
