Description

Technical Field

[0001] This utility model relates to the technical field of concrete beam and steel column connection structure, and in particular to a novel concrete beam and steel column connection structure. Background Technology

[0002] With the booming development of my country's housing construction industry, more and more buildings are adopting steel structure systems. Especially for multi-story steel structure buildings in large commercial complexes, steel columns extend to the top of the building. However, these buildings are characterized by large spans and high floor heights, thus placing strict requirements on the load-bearing capacity and safety of the steel structure. In existing technology, the common practice in the construction of steel columns and reinforced concrete beams is to drill holes in the steel columns, then connect the reinforcing bars of the reinforced concrete beams to the holes and weld them together to solve the connection problem.

[0003] In actual construction, errors are inevitable when construction workers drill holes in steel columns, causing the reinforcing bars on the earth beam to not align with the holes on the steel columns. This forces the construction workers to re-drill holes, which not only increases the difficulty of drilling but also increases the workload. Utility Model Content

[0004] The main purpose of this utility model is to provide a new type of concrete beam and steel column connection structure, which aims to reduce the difficulty of drilling and reduce the workload.

[0005] To achieve the above objectives, this utility model proposes a novel concrete beam and steel column connection structure, including a steel column and a concrete beam with several beam reinforcement bars. Each beam reinforcement bar is respectively located at one of the four corners of the concrete beam. The steel column is provided with several adjustment grooves on the side near the concrete beam. Each adjustment groove has an adjustment block slidably connected to its inner wall, and each adjustment block has an installation hole for connecting with the beam reinforcement bars.

[0006] In one possible implementation, each of the adjustment grooves is provided with a limiting groove on both sides, and each of the adjustment blocks is fixedly connected to a limiting block on both sides, wherein the limiting block is slidably connected to the inner wall of the limiting groove.

[0007] In one possible implementation, a connecting assembly is also included, comprising a fixed cylinder respectively disposed on one side of the adjusting block, and a connecting screw connecting the fixed cylinder and the beam reinforcement. Both the fixed cylinder and the beam reinforcement are provided with connecting grooves inside, and the two sides of the connecting screw are threadedly connected to the inner walls of the connecting grooves on the fixed cylinder and the beam reinforcement, respectively.

[0008] In one possible implementation, the connecting screw is fixedly connected to a rotating block on one side of the fixed cylinder and beam reinforcement, and the rotating block has a hexagonal cross-section.

[0009] In one possible implementation, a locking assembly is also included, the locking assembly comprising a double-ended stud penetrating through the fixed cylinder and the connecting screw, and first bolts respectively disposed on both sides of the double-ended stud and threadedly connected to the double-ended stud, each of the first bolts being disposed on both sides of the fixed cylinder, and one side of each first bolt abutting against the side of the fixed cylinder.

[0010] In one possible implementation, a fixing block is fixedly connected to the side of the steel column near the concrete beam, and a connecting block is fixedly connected to the side of the concrete beam. The connecting block is slidably connected to the fixing block, and the outer surface of the fixing block is provided with several second bolts for fixing the connecting block.

[0011] This utility model's technical solution, through the setting of adjustment blocks and adjustment grooves, allows for flexible changes in the position of the installation hole when construction workers make mistakes during drilling. This is because the adjustment blocks can slide within the adjustment grooves, effectively adapting to the actual positions of the beam reinforcement at the four corners of the concrete beam. This significantly reduces the probability of re-drilling due to hole position deviations, improves construction efficiency, reduces the difficulty of drilling, and decreases workload.

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Example 1:

[0022] refer to Figure 1-3 This embodiment proposes a novel concrete beam and steel column connection structure, including a steel column 1 and a concrete beam 2 with several beam reinforcing bars 201. Each beam reinforcing bar 201 is located at one of the four corners of the concrete beam 2. The steel column 1 has several adjusting grooves 101 on the side closest to the concrete beam 2. Each adjusting groove 101 has an adjusting block 102 slidably connected to its inner wall, and each adjusting block 102 has an installation hole 103 for connecting with the beam reinforcing bars 201. Furthermore, the adjusting block 102 can be designed with a square structure to prevent rotation during movement, which could cause the installation hole 103 to shift.

[0023] When construction workers make mistakes in drilling, the adjusting block 102 can slide in the adjusting groove 101, which can change the position of the mounting hole 103 in the vertical direction of the steel column 1. Then, the beam reinforcement 201 is inserted into the mounting hole 103 and welded to the inner wall of the mounting hole 103. This adapts to the actual position of the beam reinforcement 201 at the four corners of the concrete beam 2, greatly reducing the probability of re-drilling due to hole position deviation and improving construction efficiency.

[0024] When the reinforcing bars at the four corners are inserted and welded to the inner wall of the mounting hole 103, the concrete beam 2 can still slide freely in the vertical direction because the vertical freedom of the adjusting block 102 is not restricted. To avoid this, a locking block 106 can be fixedly connected to the side of the steel column 1, and a locking groove 107 that mates with the locking block 106 can be provided on the side of the concrete beam 2. When the beam reinforcing bars 201 are inserted into the inner wall of the mounting hole 103, the locking block 106 will be inserted into the locking groove 107 first, thereby restricting the vertical freedom of the concrete beam 2 and preventing it from sliding.

[0025] Furthermore, limiting grooves 104 are provided on both sides of each adjusting groove 101, and limiting blocks 105 are fixedly connected to both sides of each adjusting block 102. The limiting blocks 105 are slidably connected to the inner wall of the limiting groove 104. By setting the limiting blocks 105 and limiting grooves 104, the lateral displacement or disengagement of the adjusting block 102 during the sliding process can be prevented, ensuring the stability and accuracy of the sliding of the adjusting block 102.

[0026] Example 2:

[0027] Based on Example 1, and referring to Figure 4-5 This embodiment also includes a connecting component, which includes a fixed cylinder 3 respectively disposed on one side of the adjusting block 102, and a connecting screw 301 connecting the fixed cylinder 3 and the beam reinforcement 201. The fixed cylinder 3 and the beam reinforcement 201 are both provided with connecting grooves 302. The two sides of the connecting screw 301 are threadedly connected to the inner walls of the connecting grooves 302 on the fixed cylinder 3 and the beam reinforcement 201, respectively.

[0028] Previously, directly welding the beam reinforcement 201 to the holes on the steel column 1 was difficult and the quality was hard to guarantee. This solution uses a connecting assembly, employing a fixed cylinder 3 and a connecting screw 301 to connect the beam reinforcement 201 to the adjusting block 102. During construction, one side of the connecting screw 301 is first threaded into the connecting groove 302 inside the beam reinforcement 201, and then the other side of the connecting screw 301 is screwed into the connecting groove 302 inside the fixed cylinder 3. Compared to direct welding, this method is more convenient; workers only need to rotate the connecting screw 301 to achieve the connection, reducing construction difficulty. The threaded connection provides stable tightening force, enhancing the reliability of the connection between the beam reinforcement 201 and the steel column 1. Furthermore, this connection method allows for the disassembly of the steel column 1 and the beam reinforcement 201, enabling quick replacement of damaged concrete beams 2 without damaging the original column. Disassembly simply requires rotating the connecting screw 301 in the opposite direction to disengage one side of the connecting screw 301 from the connecting groove 302 inside the fixed cylinder 3.

[0029] In addition, a rotating block 303 is fixedly connected to the connecting screw 301 on one side of the fixed cylinder 3 and the beam reinforcement 201, and the rotating block 303 has a hexagonal cross-section. The rotating block 303 allows construction workers to easily apply force by gripping the hexagonal part of the rotating block 303 with tools such as wrenches. Compared to ordinary smooth screws, this increases the convenience and stability of force application, thereby improving construction efficiency.

[0030] In this embodiment, a locking assembly is also included. The locking assembly includes a double-ended stud 4 that passes through the fixed cylinder 3 and the connecting screw 301, and first bolts 401 that are respectively disposed on both sides of the double-ended stud 4 and threadedly connected to the double-ended stud 4. Each first bolt 401 is disposed on both sides of the fixed cylinder 3, and one side of each first bolt 401 abuts against the side of the fixed cylinder 3. The fixed cylinder 3 and the connecting screw 301 should be provided with through holes 402, and the double-ended stud 4 is disposed inside the through holes 402.

[0031] If the connection between the connecting screw 301 and the fixed cylinder 3 relies solely on the thread itself for fastening, it may loosen under long-term external forces such as structural vibrations. In this embodiment, the locking assembly, after the connecting screw 301 is installed, allows the double-ended stud 4 to pass through the through hole 402 through the fixed cylinder 3 and the connecting screw 301. Then, the first bolt 401 is tightened, pressing it firmly against the side of the fixed cylinder 3. Friction further secures the double-ended stud 4, preventing the connecting screw 301 from rotating due to external forces during use. This enhances the stability and reliability of the connection assembly, ensuring the connection between the steel column 1 and the concrete beam 2 remains stable during long-term use.

[0032] It should be noted that when using the connecting screw 301 to connect the fixed cylinder 3 and the beam reinforcement 201, one side of the connecting screw 301 must be fully screwed into the connecting groove 302 inside the fixed cylinder 3, so that the side of the connecting screw 301 abuts against the side of the connecting groove 302 of the fixed cylinder 3. When the screwing length is the same each time, when the side of the connecting screw 301 abuts against the side of the connecting groove 302 of the fixed cylinder 3, the through hole 402 on the connecting screw 301 and the through hole 402 on the fixed cylinder 3 will be on the same axis, thus facilitating the construction personnel to pass the double-ended stud 4 through the through hole 402.

[0033] Furthermore, a fixing block 403 is fixedly connected to the side of the steel column 1 near the concrete beam 2, and a connecting block 404 is fixedly connected to the side of the concrete beam 2. The connecting block 404 is internally slidably connected to the fixing block 403, and the outer surface of the fixing block 403 is provided with several second bolts 405 for fixing the connecting block 404.

[0034] With the fixed block 403 and the connecting block 404 set, when the beam reinforcement 201 is inserted into the installation hole 103, the connecting block 404 can be inserted into the fixed block 403 and complete the initial positioning of the concrete beam 2 column, so that the construction personnel can gradually connect the beam reinforcement 201 to the fixed cylinder 3 respectively, thereby further improving the construction efficiency.
