Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a reinforcement structure for building structural beams. Background Technology

[0002] This utility model relates to the field of building structure reinforcement technology, specifically a beam reinforcement structure for building structures. Throughout the entire life cycle of a building, due to changes in its function, increased load, stricter seismic fortification standards, material aging, environmental erosion, and other factors, it is often necessary to maintain and reinforce existing structures to ensure their safety and durability. Beam-column joints, as key hubs for force transmission in frame structures, directly affect the stability and safety of the entire structural system through their load-bearing capacity and ductility. Especially under seismic loading, the joint area bears complex shear forces and bending moments, making it one of the weakest links in the structural system. Therefore, developing efficient, reliable, and easy-to-construct beam-column joint reinforcement technologies is of great engineering significance and social value for improving the safety reserves of existing buildings and extending their service life, and is an important topic of continuous attention and research in the field of civil engineering.

[0003] Existing technologies for reinforcing beam-column joints mainly include methods such as increasing the cross-section and external steel wrapping. The core principle lies in adding external reinforcing components to form an integral whole with the original structure, jointly bearing external loads. For example, increasing the cross-section requires first chiseling away the concrete surface of the original component, inserting new reinforcing bars, then erecting formwork, and finally pouring high-strength concrete—a complex process. Similarly, the external steel wrapping method requires welding and assembling prefabricated steel plates or angle steel on-site to form a steel sleeve that encloses the joint, and then injecting high-strength epoxy mortar or cement-based grout into the gap between the sleeve and the concrete, achieving reinforcement through the combination of these two methods. All these methods rely on multiple on-site wet operations to ultimately strengthen the component.

[0004] However, existing technologies have significant shortcomings in practical applications. Traditional reinforcement methods are generally complex and time-consuming. Taking the enlarged cross-section method or wet steel cladding method as examples, it involves not only multiple steps such as chiseling, rebar installation, and welding, but more importantly, it includes concrete pouring or grouting. These wet operations are accompanied by a long curing period, during which the reinforced part cannot bear the load, seriously affecting the overall construction progress. At the same time, these processes often require the entry of large equipment, the on-site working environment is harsh, and there is significant interference with the existing building. This complex, time-consuming, and interconnected construction mode makes it unable to meet the needs of rapid and efficient reinforcement, and it is difficult to cope with reinforcement projects with tight schedules or those that need to minimize construction impact. Therefore, a structural beam reinforcement structure is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a structural beam reinforcement structure for buildings, which aims to improve the problem that the reinforcement in the prior art is relatively complex and cannot quickly strengthen the connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A building structural beam reinforcement structure includes a column, a main beam at the top of the column, and a reinforcement component at the bottom of the main beam; The reinforcement assembly includes a first reinforcement plate and a second reinforcement plate. The top of the first reinforcement plate is disposed at the bottom of the main beam, and the outer wall of the second reinforcement plate is disposed at the outer wall of the column. The outer walls of the first reinforcement plate and the second reinforcement plate are both fixedly connected with screws. The outer walls of the screws are slidably connected to the inside of the column and the main beam. An adhesive layer is fixedly connected to the outer walls of the screws. A connecting assembly is disposed between the first reinforcement plate and the second reinforcement plate.

[0007] As a further description of the above technical solution: The connecting assembly includes a first connecting block and two second connecting blocks, with the bottom of the first connecting block fixedly connected to the top of the second reinforcing plate.

[0008] As a further description of the above technical solution: The reinforcing plate has a limiting groove inside, and the outer walls of the two connecting blocks are located on both sides of the connecting block.

[0009] As a further description of the above technical solution: A slider is fixedly connected to the outer wall of the second connecting block, and the outer wall of the slider is slidably connected inside the limiting groove.

[0010] As a further description of the above technical solution: Both sides of the connecting block one are fixedly connected with fixing teeth, and the outer wall of the connecting block two is fixedly connected with locking teeth, which mesh with the fixing teeth.

[0011] As a further description of the above technical solution: The first connecting block has a limiting groove inside, and the second connecting block has a connecting rod fixedly connected to its outer wall.

[0012] As a further description of the above technical solution: One end of the connecting rod is fixedly connected to a limiting disk, and the outer wall of the limiting disk is slidably connected inside the limiting groove.

[0013] As a further description of the above technical solution: A spring is fitted on the outer wall of the connecting rod. One end of the spring is fixedly connected to the inner wall of the limiting groove, and the other end of the spring is fixedly connected to the outer wall of the limiting disc.

[0014] This utility model has the following beneficial effects: 1. In this utility model, two steel plates are hinged together by a high-strength pivot. During installation, they are rigidly locked to the original beams and columns through an adhesive layer and screws, which ensures the effective transmission of force. This solves the problem that traditional reinforcement is relatively complex and cannot quickly strengthen the connection, improves construction efficiency and installation accuracy, and ensures uniform stress and collaborative performance between the reinforcement system and the original structure.

[0015] 2. In this utility model, the sawtooth meshing locking allows for free adjustment of the angle during installation, perfectly matching the non-standard included angle between beams and columns. This ensures seamless contact between the reinforcing plate and the surface of the component, and allows all anchor bolts to be evenly stressed under optimal conditions. This solves the problem that traditional fixed-angle reinforcing components cannot be tightly fitted due to construction errors or special design features. By achieving standardization and universality of reinforcing components, it greatly improves installation efficiency, reinforcement reliability, and the overall collaborative performance of the structure.

[0018] 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.

[0019] Reference Figures 1-3 The present invention provides an embodiment of a building structural beam reinforcement structure, comprising a column 1, a main beam 2 provided at the top of the column 1, and a reinforcement component provided at the bottom of the main beam 2; The reinforcement components include reinforcement plate 3 and reinforcement plate 4, both made of high-strength structural steel. They possess excellent load-bearing capacity, plasticity, and weldability, and are commonly used materials in the field of structural engineering, so further details will not be provided here. Reinforcement plate 3 is positioned at the bottom of the main beam 2, and reinforcement plate 4 is positioned on the outer wall of the column 1. Both reinforcement plates 3 and 4 are fixedly connected to screw rods 6. The outer walls of screw rods 6 are slidably connected to the inside of the column 1 and the main beam 2. An adhesive layer 5, a two-component high-strength chemical anchoring adhesive, is fixedly connected to the outer wall of screw rods 6. This layer is used to firmly anchor the screw rods 6 into pre-drilled holes inside the column 1 and the main beam 2, thereby preventing the screw rods 6 from being pulled out and ensuring effective force transmission between the reinforcement system and the original structure. A connecting component is provided between reinforcement plate 3 and reinforcement plate 4.

[0020] Specifically, during the reinforcement installation of column 1 and main beam 2, the positions are first precisely located according to the design drawings, and holes are drilled at the corresponding positions on column 1 and main beam 2. The holes are then thoroughly cleaned to ensure anchoring quality. Next, high-strength chemical anchoring adhesive, serving as the bonding layer 5, is injected into the holes, and then the screw 6 is rotated and inserted into the holes. After the bonding layer 5 has fully cured, the reinforcing plate 3 and reinforcing plate 4 are tightly attached to the surfaces of column 1 and main beam 2, forming a stable rigid connection.

[0021] Reference Figures 1-5The connecting assembly includes a first connecting block 7 and two second connecting blocks 8. The bottom of the first connecting block 7 is fixedly connected to the top of the second reinforcing plate 4. A limiting groove 9 is opened inside the first reinforcing plate 3. The outer walls of the two second connecting blocks 8 are set on both sides of the first connecting block 7. A slider 10 is fixedly connected to the outer wall of the second connecting block 8. The outer wall of the slider 10 is slidably connected inside the limiting groove 9. Fixed teeth 12 are fixedly connected to both sides of the first connecting block 7. A locking tooth 11 is fixedly connected to the outer wall of the second connecting block 8. The locking tooth 11 meshes with the fixed tooth 12. The fixed tooth 12 and the locking tooth 11 are both made of chromium-molybdenum alloy steel with high-frequency quenching treatment. They have high surface hardness and wear resistance. Their function is to provide reliable, gapless mechanical locking. This is common knowledge and will not be elaborated further here. In a static state, the locking teeth 11 and the fixing teeth 12 mesh with each other to firmly lock the adjusted angle, thereby preventing any slight rotation due to structural stress and ensuring the stability after reinforcement. The connecting block 1 7 has a limiting groove 15 inside. The connecting block 2 8 has a connecting rod 16 fixedly connected to its outer wall. One end of the connecting rod 16 is fixedly connected to a limiting disc 13. The outer wall of the limiting disc 13 is slidably connected to the inside of the limiting groove 15. The outer wall of the connecting rod 16 is fitted with a spring 14. One end of the spring 14 is fixedly connected to the inner wall of the limiting groove 15, and the other end of the spring 14 is fixedly connected to the outer wall of the limiting disc 13.

[0022] Specifically, when reinforcement is needed for beam-column joints at different angles, the unique angle adjustment and locking mechanism of this structure begins to operate. The operator first pulls outward on connecting block 2 (acting as a handle), which then drives the internal slider 10 to slide within the limiting groove 9. This action is transmitted through connecting rod 16, forcing the limiting disc 13 to translate within the limiting groove 15, thereby compressing the normally closed locking spring 14. After compression, the spring 14's thrust on the locking teeth 11 disappears, releasing the precise engagement between the locking teeth 11 and the fixed teeth 12. At this point, the entire pivot is unlocked, allowing the operator to freely rotate connecting block 1 (serving as the main pivot), enabling the reinforcement plate to precisely fit the actual angle between the column 1 and the main beam 2, achieving a perfect fit. Once the angle is adjusted, connecting block 2 (acting as a handle) is released, and the compressed spring 14 instantly rebounds, driving the entire linkage mechanism to reset, causing the locking teeth 11 and the fixed teeth 12 to re-engage and lock, thus firmly fixing the new angle.

[0023] Working principle: When reinforcing column 1 and main beam 2, firstly, holes are drilled in column 1 and main beam 2, then screws 6 are inserted into column 1 and main beam 2, so that reinforcing plate 1 3 and reinforcing plate 2 4 are attached to column 1 and main beam 2. Then, the screws 6 are connected to the opening holes through the adhesive layer 5 to maintain the stability of the reinforcement. In addition, when reinforcing the included angle at different angles, the second connecting block 8 can be pulled, which drives the slider 10 to slide inside the limiting groove 9. Then, the second connecting block 8 drives the connecting rod 16 to move, and at the same time, the connecting rod 16 drives the limiting disc 13 to slide inside the limiting groove 15, compressing the spring 14, thereby releasing the engagement between the locking tooth 11 and the fixed tooth 12. Only then can the first connecting block 7 be rotated, so that the reinforcing plate fits more closely with the column 1 and the main beam 2. Then, the second connecting block 8 is released, and the spring 14 rebounds, causing the locking tooth 11 to engage with the fixed tooth 12, keeping the angle fixed.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
