Description

Technical Field

[0001] This utility model relates to the field of beam reinforcement technology, specifically a beam reinforcement structure for building structures. Background Technology

[0002] As an important component of a building, structural beams bear the loads from floors, roofs, and other surfaces, and transfer them to structural members such as columns and foundations. They are key components that ensure the structural stability and safety of a building.

[0003] Building materials age over time. Concrete experiences carbonization, shrinkage, and creep, leading to a decrease in its strength and durability. Steel bars are prone to corrosion due to damage to the concrete cover and external environmental erosion during long-term use. This reduces the effective cross-sectional area of ​​the steel bars and decreases their bond with the concrete, thus affecting the overall performance of the structural beams. Statistics show that in buildings with a service life of more than 50 years, the performance degradation of structural beams due to material aging is quite common.

[0004] Traditional methods of strengthening beams by increasing their cross-section require pouring a new layer of concrete on the surface of the original structural beam and laying matching steel bars. This process significantly increases the weight of the structural beam, leading to a substantial increase in the vertical load on the building. This increase in weight places a heavy burden on the building's foundation.

[0005] Therefore, this utility model provides a structural beam reinforcement structure to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a structural beam reinforcement structure for buildings, aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: It includes a reinforcing beam with rounded corners on its upper surface. The reinforcing beam is integrally formed by two crossbeams, with a connecting section between the two crossbeams. The upper surface of the reinforcing beam has a concave section. An inner lining beam is fitted inside one of the crossbeams of the reinforcing beam. One side surface of the inner lining beam has an opening. Both sides of the inner lining beam near the opening have bent portions. Both the upper and lower surfaces of the inner lining beam have recessed ends. The lower surface of the concave section movably abuts against the surface of the recessed end. A rubber ring is attached to the side of the reinforcing beam near the opening. One side surface of the rubber ring abuts against a fastening nut. A screw is threadedly connected to one side of the fastening nut.

[0010] As a preferred technical solution of this application, one end of the screw penetrates into the inner side of the reinforcing beam, and a sealing block is fixedly installed at the end of the screw penetrating the reinforcing beam, with one side surface of the sealing block adhering to the inner wall of the reinforcing beam.

[0011] As a preferred technical solution of this application, a snap-fit ​​block is provided on one side of the sealing block, and a pressing end is provided in the middle of one side surface of the snap-fit ​​block, and one side surface of the pressing end is in contact with one side of the sealing block.

[0012] As a preferred technical solution of this application, the outer arc surface of the snap-fit ​​block is provided with an adapter groove on both sides, the inner arc surface of the two adapter grooves is movably snapped with one end of the bent part, and one side of the abutting end is placed at the opening on one side of the inner lining beam.

[0013] As a preferred technical solution of this application, the inner lining beam is provided with an expansion plate on the side away from the sealing block, and one side surface of the expansion plate is provided with a protruding end.

[0014] As a preferred technical solution of this application, the expansion plate is provided with fitting edges on both sides near the protruding end, one side surface of the fitting edge abuts against one side inner wall of the inner lining beam, and one end of the screw abuts against the surface of the protruding end.

[0015] (III) Beneficial Effects

[0016] By generating strong pre-pressure between the reinforcing beam and the inner lining beam, and between the snap-fit ​​block and the expansion plate, this pre-pressure not only enhances the synergistic effect between the reinforcing beam and the inner lining beam, but also effectively suppresses the deformation that may occur in the beam under load. With its expansion force, it forms a stable state of mutual clamping with the snap-fit ​​block. This mechanism further strengthens the connection strength between the reinforcing beam and the inner lining beam, prevents relative displacement between the two during the stress process, and ensures that the two can achieve more efficient synergistic work under complex stress conditions.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a structural beam reinforcement structure for buildings, such as Figures 1 to 4 As shown, the device includes a reinforcing beam 1 with a rounded corner 101 on its upper surface. The reinforcing beam 1 is integrally formed by two crossbeams, with a connecting section 102 between the two crossbeams. The upper surface of the reinforcing beam 1 has a recessed section 103. An inner lining beam 2 is fitted inside one of the crossbeams of the reinforcing beam 1. One side surface of the inner lining beam 2 has an opening 201, and both sides of the inner lining beam 2 near the opening 201 have bent portions 202. Both the upper and lower surfaces of the inner lining beam 2 are provided with… The lower surface of the recessed end 203 and the concave section 103 movably abuts against the surface of the recessed end 203. A rubber ring 3 is attached to the side of the reinforcing beam 1 near the opening 201. A fastening nut 4 is attached to one side of the surface of the rubber ring 3. A screw 5 is threaded to one side of the fastening nut 4. One end of the screw 5 passes through the inner side of the reinforcing beam 1. A sealing block 6 is fixedly installed at the end of the screw 5 that passes through the reinforcing beam 1. One side of the sealing block 6 is attached to the inner wall of the reinforcing beam 1.

[0025] As the main load-bearing component of the entire reinforcement system, the innovative integrated design of the connecting section 102 and the concave section 103 of the reinforcing beam 1 expands the contact area with the inner lining beam 2. Through this close fit, the inner lining beam 2 and the reinforcing beam 1 work together efficiently, rationally distributing the load borne by the original beam and significantly improving the overall load-bearing capacity of the beam. The ingenious design of the opening 201 and the concave end 203 provides space for the installation of the screw 5 and the sealing block 6. During installation, the screw 5 passes through the reinforcing beam 1 and the inner lining beam 2 in sequence. By tightening the fastening nut 4, a strong preload is generated between the two. This preload not only enhances the synergistic effect between the reinforcing beam 1 and the inner lining beam 2, but also effectively suppresses the deformation that may occur in the beam under load.

[0026] A snap-fit ​​block 7 is provided on one side of the sealing pressure block 6. A clamping end 701 is provided in the middle of one side surface of the snap-fit ​​block 7. One side surface of the clamping end 701 is in contact with one side of the sealing pressure block 6. Both sides of the outer arc surface of the snap-fit ​​block 7 are provided with an adapter groove 702. The inner arc surface of the two adapter grooves 702 is movably snapped with one end of the bent part 202. One side end face of the clamping end 701 is placed at the opening 201 on one side of the inner lining beam 2. An expansion plate 8 is provided on the side of the inner lining beam 2 away from the sealing pressure block 6. A protruding end 801 is provided on one side surface of the expansion plate 8. Both sides of the expansion plate 8 near the protruding end 801 are provided with a fitting edge 802. One side surface of the fitting edge 802 abuts against the inner wall of one side of the inner lining beam 2. One end of the screw 5 abuts against the surface of the protruding end 801.

[0027] At the connection between the reinforced beam 1 and the inner lining beam 2, the rubber ring 3 plays multiple key roles. With its excellent elasticity, the rubber ring 3 can fill the tiny gaps between the two, forming an effective sealing barrier to prevent the intrusion of harmful external media such as moisture and corrosive substances, thereby slowing down the corrosion process of the steel bars inside the beam and extending the service life of the beam. In addition, when the beam is subjected to vibration or impact loads, the rubber ring 3, as a highly efficient buffer element, can absorb some energy, effectively reduce the vibration response of the beam, and mitigate the structural damage caused by vibration.

[0028] The snap-fit ​​block 7 and the expansion plate 8 achieve a tight fit through a unique structural design. The snap-fit ​​block 7 is installed at a specific location on the reinforcing beam 1 or the inner lining beam 2, while the expansion plate 8 undergoes elastic deformation under stress. When the screw 5 is tightened, the contact edge 802 of the expansion plate 8 fits tightly against the beam surface, forming a stable, mutually abutting state with the snap-fit ​​block 7 due to its expansion force. This mechanism further strengthens the connection between the reinforcing beam 1 and the inner lining beam 2, preventing relative displacement between the two during stress and ensuring that they can work together more efficiently under complex stress conditions.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
