Abstract
Description
Technical Field
[0001] This application relates to the field of beam hole reinforcement technology, and in particular to a beam hole reinforcement structure. Background Technology
[0002] During construction or renovation, it is often necessary to create openings in beams to accommodate equipment installation, pipeline passage, and other needs. However, these openings can weaken the beam cross-section, thereby affecting the safety and load-bearing capacity of the entire building structure. To address this issue, existing beam opening reinforcement technologies are constantly improving, aiming to enhance the strength and stiffness of the area surrounding the beam opening and reduce its impact on the overall structural performance.
[0003] Currently, common methods for reinforcing beam openings mainly include the following: steel plate reinforcement, which enhances local strength by welding or pasting steel plates around the beam opening. This method is simple and easy to implement, but in practical applications, it is prone to stress concentration, welding quality is difficult to guarantee, and improper selection of steel plate thickness can affect the reinforcement effect; fiber composite reinforcement, which uses carbon fiber cloth or glass fiber cloth to wrap around the beam opening to increase tensile strength. This reinforcement method is lightweight and easy to construct, but it is costly, and its long-term durability needs to be verified; prestressed steel reinforcement, which arranges prestressed steel bars around the beam opening and uses tensioning to generate pre-compression stress in the steel bars, thereby improving the overall load-bearing capacity of the beam. This method can effectively improve the stress state of the beam, but the construction is complex, expensive, and requires a professional construction team and technical support. Although these methods improve the reinforcement effect of beam openings to a certain extent, they also have obvious limitations.
[0004] Therefore, existing beam hole reinforcement methods generally have the following defects: steel plate reinforcement is prone to stress concentration, welding quality is difficult to guarantee, and reinforcement effect is unstable; fiber composite reinforcement is simple to construct but has high cost, and its long-term durability needs further research; prestressed steel reinforcement can significantly improve the beam bearing capacity, but it is difficult to construct, costly, and requires high professional skills from construction personnel.
[0005] Therefore, this application proposes a beam hole reinforcement structure. Utility Model Content

Compared with the prior art, this technical solution significantly improves the strength and stiffness of the area surrounding the beam hole by using a closed reinforcing ring composed of high-strength steel and rectangular steel plates, effectively avoiding stress concentration. High-strength bolts and expansion bolts are used for connection and fixation, ensuring the stability and reliability of the reinforcement structure. The construction process is simplified, and the construction difficulty and cost are reduced. Elastic shims can be added between the main reinforcement and the secondary reinforcement, further improving the seismic performance and service life of the reinforcement structure. It is particularly suitable for noise-sensitive building environments, greatly enhancing the practicality of the device.
[0007] To achieve the above objectives, this application adopts the following technical solution:

The beam hole is opened inside the beam body. The main reinforcement member is made of high-strength steel and is U-shaped, with its two side flanges tightly attached to the beam body surface above and below the beam hole, respectively. The secondary reinforcement member is provided on the outside of the main reinforcement member.
[0009] In one preferred embodiment, the auxiliary reinforcement components are divided into two groups, one group being a first reinforcement component with two components, and the other group being a second reinforcement component with two components.

[0013] In a preferred embodiment, the secondary reinforcement is a rectangular steel plate, which is fixed to the two side flanges of the main reinforcement by the main reinforcement to form a closed reinforcing ring;
[0014] By using a closed reinforcing ring composed of high-strength steel and rectangular steel plates, the strength and stiffness of the area surrounding the beam hole are significantly improved, effectively avoiding stress concentration and thus enhancing the practicality of the device.
[0015] In a preferred embodiment, the anchor is an expansion bolt, which is installed in the concrete around the beam hole to firmly fix the main reinforcement and the secondary reinforcement to the beam.
[0016] By using expansion bolts to firmly fix the main and secondary reinforcement components to the beam, the stability and reliability of the entire reinforcement structure are ensured. In this way, not only can the strength and stiffness of the area around the beam hole be effectively improved, but stress concentration can also be avoided, extending the service life of the beam and thus improving the practicality of the device.
[0017] In a preferred embodiment, an elastic gasket is added between the main reinforcement member and the secondary reinforcement member to absorb and disperse vibration energy, thereby further improving the seismic performance of the reinforced structure.
[0018] By using elastic gaskets made of rubber or polyurethane with a thickness of not less than five millimeters, this solution can not only improve the stability and safety of the beam hole reinforcement structure, but also extend its service life. In addition, the elastic gaskets also have the effect of vibration reduction and noise reduction, making them suitable for noise-sensitive building environments, thereby improving the practicality of the device.
[0019] The beneficial effects of this application are:
[0020] 1. Compared with existing technologies, this beam hole reinforcement structure significantly improves the strength and stiffness of the area surrounding the beam hole by using a closed reinforcing ring composed of high-strength steel and rectangular steel plates, effectively avoiding stress concentration. The use of high-strength bolts and expansion bolts for connection and fixation ensures the stability and reliability of the reinforcement structure, simplifies the construction process, and reduces construction difficulty and cost.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0027] Reference Figure 1-3 A beam hole reinforcement structure includes a beam body 1, a beam hole 2, a main reinforcement 3, a secondary reinforcement 4, a connector 5, an anchor 6, and an elastic gasket 7. The beam hole 2 is opened inside the beam body 1. The main reinforcement 3 is made of high-strength steel and is U-shaped. Its two side flanges are respectively attached to the surface of the beam body 1 above and below the beam hole 2. The secondary reinforcement 4 is provided on the outside of the main reinforcement 3.
[0028] The auxiliary reinforcement 4 is divided into two groups, one group is the first reinforcement 41, which has two components, and the other group is the second reinforcement 42, which also has two components. By fixing the auxiliary reinforcement 4 to the two side flanges of the main reinforcement 3 through the connector 5, a closed reinforcing ring is formed, thereby improving the practicality of the device.
[0029] The connector 5 is a high-strength bolt used to tightly connect the main reinforcement 3 and the secondary reinforcement 4 together. By using the high-strength bolt of the connector 5 to tightly connect the main reinforcement 3 and the secondary reinforcement 4 together, the secondary reinforcement 4 is fixed to the two side flanges of the main reinforcement 3, thereby improving the practicality of the device.
[0030] The secondary reinforcement 4 is a rectangular steel plate, which is fixed to the two side flanges of the main reinforcement 3 through the main reinforcement 3 to form a closed reinforcing ring. By using a closed reinforcing ring composed of high-strength steel and rectangular steel plate, the strength and stiffness of the area around the beam hole 2 are significantly improved, effectively avoiding stress concentration and thus improving the practicality of the device.
[0031] Anchor 6 is an expansion bolt, installed in the concrete around the beam hole 2, to firmly fix the main reinforcement 3 and the secondary reinforcement 4 to the beam 1. By using expansion bolts to firmly fix the main reinforcement 3 and the secondary reinforcement 4 to the beam 1, the stability and reliability of the entire reinforcement structure are ensured. In this way, not only can the strength and stiffness of the area around the beam hole 2 be effectively improved, but stress concentration can also be avoided, the service life of the beam 1 can be extended, and thus the practicality of the device can be improved.
[0032] An elastic gasket 7 is added between the main reinforcement 3 and the secondary reinforcement 4 to absorb and disperse vibration energy, further improving the seismic performance of the reinforced structure. The elastic gasket 7 is made of rubber or polyurethane material with a thickness of not less than five millimeters. This solution can not only improve the stability and safety of the beam hole 2 reinforcement structure, but also extend its service life. In addition, the elastic gasket 7 also has the effect of vibration reduction and noise reduction, which is suitable for noise-sensitive building environments, thereby improving the practicality of the device.
[0033] Working Principle: During construction, the main reinforcement component 3 is first installed on the surface of the beam 1 above and below the beam hole 2, ensuring that its two side flanges are tightly attached to the beam 1. Then, the secondary reinforcement component 4 is fixed to the two side flanges of the main reinforcement component 3 through the connector 5, forming a closed reinforcing ring. Finally, expansion bolts are used to firmly fix the main reinforcement component 3 and the secondary reinforcement component 4 to the beam 1, ensuring the stability and reliability of the entire reinforcement structure. In this way, not only can the strength and stiffness of the area around the beam hole 2 be effectively improved, but stress concentration can also be avoided, extending the service life of the beam 1. By adding an elastic gasket 7 between the main reinforcement component 3 and the secondary reinforcement component 4 to absorb and disperse vibration energy, the seismic performance of the reinforcement structure is further improved. The elastic gasket 7 can be made of rubber or polyurethane material with a thickness of not less than 5mm. This solution not only improves the stability and safety of the beam hole 2 reinforcement structure but also extends its service life. In addition, the elastic gasket 7 also has the functions of vibration reduction and noise reduction. This method is suitable for noise-sensitive building environments. Regarding the operating procedures and precautions: Measure the dimensions of beam hole 2 to determine the specific dimensions of the main reinforcement 3 and secondary reinforcement 4. Mark the installation positions of the main reinforcement 3 on the surface of beam 1 above and below beam hole 2, ensuring its two side flanges are tightly against beam 1. Install the main reinforcement 3 in the marked positions and secure it with temporary supports. Place the secondary reinforcement 4 on the two side flanges of the main reinforcement 3, ensuring its contact surface with the main reinforcement 3 is flat. Use high-strength bolts to tightly connect the main reinforcement 3 and secondary reinforcement 4 together, ensuring no looseness at the connection points. Drill holes in the concrete around beam hole 2 with a depth of not less than 50mm and a diameter matching the expansion bolts. Install the expansion bolts in the drilled holes and tighten them with a wrench, ensuring the main reinforcement 3 and secondary reinforcement 4 are firmly fixed to beam 1. Check that all connections are tight. After confirming everything is correct, remove the temporary supports and clean the construction site, ensuring the construction area is tidy.
[0034] The main reinforcement 3 is made of high-strength steel and is U-shaped. Its two flanges are tightly attached to the surface of the beam 1 above and below the beam hole 2, respectively. The secondary reinforcement 4 is a rectangular steel plate, which is fixed to the two flanges of the main reinforcement 3 by the connector 5 to form a closed reinforcing ring. The connector 5 is a high-strength bolt, which is used to tightly connect the main reinforcement 3 and the secondary reinforcement 4 together. The anchor 6 is an expansion bolt, which is installed in the concrete around the beam hole 2 to firmly fix the main reinforcement 3 and the secondary reinforcement 4 to the beam 1.
[0035] Compared with existing technologies, this technical solution significantly improves the strength and stiffness of the area surrounding the beam hole 2 by using a closed reinforcing ring composed of high-strength steel and rectangular steel plates, effectively avoiding stress concentration. The use of high-strength bolts and expansion bolts for connection and fixation ensures the stability and reliability of the reinforced structure, simplifies the construction process, and reduces construction difficulty and cost. Elastic shims 7 can be added between the main reinforcing member 3 and the secondary reinforcing member 4, further improving the seismic performance and service life of the reinforced structure. It is particularly suitable for noise-sensitive building environments.
