Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially to a beam reinforcing hoop structure. BACKGROUND

[0002] With the acceleration of urbanization, the construction industry has increasingly high requirements for structural safety and durability. Although traditional reinforced concrete beams have good overall performance, they still face problems such as insufficient strength and poor seismic performance in certain specific conditions, such as earthquake-prone areas or super high-rise buildings. In order to improve the load-carrying capacity and seismic performance of these beams, various reinforcement techniques and materials have been proposed and researched, including increasing the cross-sectional size, prestressed reinforcement, and carbon fiber cloth wrapping.

[0003] The current commonly used reinforcement methods include but are not limited to: 1. Thickening method, which increases the bending resistance of the beam by increasing the thickness of the original beam section. This method can effectively enhance the stiffness of the beam body, but it requires the removal of the old decorative layer and even part of the wall, resulting in a large amount of work, a long construction period, and high cost. 2. Prestressed reinforcement method, which uses prestressed steel strands to apply initial tension to make the concrete in a compressed state, thereby improving the overall load-carrying capacity of the beam. However, this method requires high construction precision, and improper operation can easily cause safety hazards. 3. External adhesive composite material method, such as carbon fiber sheet (CFRP), which adheres high-strength composite materials to the surface of the beam to achieve lightweight and strengthening purposes. However, CFRP has a relatively high cost, and long-term exposure to the environment may affect its performance.

[0004] Although the existing beam reinforcement methods can solve the problem to some extent, they each have obvious limitations. The thickening method not only increases the self-weight burden but also destroys the original architectural beauty. The prestressed reinforcement method is not suitable for widespread promotion due to high cost and complex construction process. The external adhesive composite material method is efficient and convenient, but it faces challenges in cost and durability. SUMMARY

[0012] As a preferred embodiment, a first steel wire band is arranged between the first beam body and the second U-shaped stirrup, and the first beam body and the second U-shaped stirrup are connected through the first steel wire band.

[0026] Reference Figure 1The top of the main reinforcement 3 and between the two first U-shaped stirrups 2 are fixedly connected with second vertical support bars 4, and the bottom of the main reinforcement 3 and between the two second U-shaped stirrups 11 are fixedly connected with first vertical support bars 5. Through the combined use of the second vertical support bars 4 and the first vertical support bars 5, the stability of the system can be further enhanced, and the phenomenon of local deformation when subjected to impact load can be prevented.

[0027] Reference Figure 1 The first vertical support bar 5 and the second vertical support bar 4 form a triangular support structure. The center of the second vertical support bar 4 and the first vertical support bar 5 are fixedly connected with a ball 10. By setting the second vertical support bar 4 and the first vertical support bar 5 into a triangular structure, a three-sided support force can be formed, so that a firm connection relationship is formed between the two U-shaped stirrups and the main bar 3.

[0028] Reference Figure 3 A first steel wire tie 7 is provided between the first beam 1 and the second U-shaped stirrup 11.

The first U-shaped stirrup 2, the second U-shaped stirrup 11 and the main bar 3 are all made of hot-rolled ribbed steel bars. By using hot-rolled ribbed steel bars, sufficient strength and ductility are ensured.

[0031] Working principle: When the beam is subjected to external loads, the first U-shaped stirrups 2 and the second U-shaped stirrups 11 form a stable frame system with the main reinforcement 3, which can effectively distribute the load and avoid local damage caused by concentrated force at a single location. At the same time, several second vertical support bars 4 and first vertical support bars 5 are set between every two U-shaped stirrups, which further enhance the stability of the system and prevent local deformation when subjected to impact loads.

[0032] By using the transverse short steel bars 6, the various U-shaped stirrups can restrain each other, preventing damage to individual parts from rapidly spreading to the entire structure and improving the overall safety factor. In addition, the design of the transverse short steel bars 6 increases the structural stiffness in the vertical direction, helping to resist pressure from above. This solution can significantly improve the load-bearing capacity and seismic performance of the beam without significantly increasing the structural self-weight, making it particularly suitable for renovation and upgrading of old buildings or new construction projects where higher seismic performance is required.
