Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or equipment including the element.

[0029] As Figure 1 shown, the building structure design beam reinforcing structure of the application includes the following main parts: the original structure beam 1, the outer reinforcing layer 2, the anchoring plate 3, the prestressed pull rod 4 and the adhesive layer 5. These components act together to improve the carrying capacity of the original structure beam 1 and the stability of the overall structure.

[0030] The original structure beam 1 is a beam in the existing building, usually made of concrete or steel, used to support various loads of the building. In order to improve the carrying capacity of the original structure beam 1, the application proposes an outer reinforcing layer 2, which is wrapped on the outer side of the original structure beam 1. The outer reinforcing layer 2 is usually composed of high-performance composite materials or reinforced concrete, and its thickness and material are selected according to the specific engineering requirements. By wrapping the outer reinforcing layer 2, the stiffness and strength of the original structure beam 1 are significantly improved.

[0031] The anchoring plate 3 is a metal component arranged inside the external reinforcement layer 2 along the length direction of the original structure beam 1. The main function of the anchoring plate 3 is to enhance the bonding force between the external reinforcement layer 2 and the original structure beam 1, preventing the separation between the two. The anchoring plate 3 is usually made of high-strength steel plate, with rough surface treatment to increase friction. The pre-stressed tension rod 4 passes through the anchoring plate 3 and is fixed on the original structure beam 1, forming a close contact between the anchoring plate 3 and the original structure beam 1 by applying pre-tensioning force. The pre-stressed tension rod 4 can be made of high-strength threaded steel, with special anchorage devices at both ends to fix and adjust the pre-tensioning force.

[0032] The adhesive layer 5 is located between the external reinforcement layer 2 and the original structure beam 1, used to further increase the bonding strength between the two. The adhesive layer 5 is usually composed of high-performance structural glue, which has excellent mechanical properties and weather resistance, and can maintain good bonding effect in different temperature and humidity environments. In the specific implementation process, the adhesive can be uniformly applied on the inner surface of the external reinforcement layer 2 or the outer surface of the original structure beam 1 by spray gun or smearing method, and then the external reinforcement layer 2 and the original structure beam 1 are closely combined.

[0033] Specifically, first, the original structure beam 1 needs to be detected to determine its specific size, material and defect condition. According to the detection result, the appropriate material and thickness of the external reinforcement layer 2 are selected and pre-processed. Then, a layer of primer is coated on the surface of the original structure beam 1 to increase the adhesion of the surface. Next, the adhesive layer 5 is uniformly applied on the inner surface of the external reinforcement layer 2, and then the external reinforcement layer 2 is accurately wrapped on the original structure beam 1. In this process, the anchoring plate 3 has been pre-fixed at the specified position inside the external reinforcement layer 2. After installation, the pre-stressed tension rod 4 is passed through the anchoring plate 3 by the pre-stressed equipment and pre-tensioning force is applied, and finally fixed on the original structure beam 1.

[0034] The reinforcement structure can effectively solve the problem of local slip and failure caused by unstable bonding performance between the external reinforcement layer 2 and the original structure beam 1. The combined action of the anchoring plate 3 and the pre-stressed tension rod 4 ensures that the bonding force between the external reinforcement layer 2 and the original structure beam 1 is evenly distributed, avoiding the slip phenomenon caused by local stress concentration. At the same time, the high-performance adhesive layer 5 further enhances the bonding strength of the two, improving the stability and reliability of the overall structure. Through these design and process measures, the reinforced beam not only improves the carrying capacity, but also significantly prolongs the service life, ensuring the safety of the building.

[0035] In one embodiment, as Figure 2As shown, the external reinforcement layer 2 of the beam reinforcement structure in the building structure design of the present application is a multi-layer composite structure, which includes, from inside to outside, a carbon fiber reinforced composite material layer 6, a glass fiber fabric layer 7, and a high-strength concrete protective layer 8. Each of the three layers has a unique function, and together they act on the overall reinforcement system to improve the reinforcement effect. The carbon fiber reinforced composite material layer 6 is located at the innermost side and directly contacts the original structure beam 1, mainly playing the role of enhancing the stiffness and load-bearing capacity of the structure. Due to the high strength and light weight characteristics of the carbon fiber reinforced composite material, it can effectively transfer stress and reduce the deformation of the original structure beam 1. The glass fiber fabric layer 7 serves as an intermediate layer, has high toughness and tensile properties, can effectively disperse stress when bearing load, reduce the separation phenomenon between structure layers, and also improve the integrity and stability of the entire reinforcement system. The high-strength concrete protective layer 8 is located at the outermost side, providing good protection against environmental factors such as water vapor and temperature changes affecting the internal reinforcement materials, while increasing the overall durability of the structure.

[0036] For example, the surface of the original structure beam 1 can be first cleaned and treated to ensure that there is no dust and impurities, then a high-performance structural adhesive is applied, and the carbon fiber reinforced composite material is laid on the surface to ensure complete adhesion. Then, a layer of glass fiber fabric is covered, and the same adhesive is used for fixation. Finally, high-strength concrete is poured to form a protective layer. Each layer of material needs to be strictly operated according to the process requirements to ensure the tight combination and seamless transition between layers. In this way, not only the overall performance of the external reinforcement layer 2 is improved, but also the problems of local slippage and failure caused by changes in temperature and humidity are effectively avoided. Specifically, this process requires a professional construction team and technical support to ensure accurate execution at each step.

[0037] In one embodiment, as Figure 3 shown, the anchor plate 3 of the beam reinforcement structure in the building structure design of the present application includes a plurality of first reinforcing ribs 9 and second reinforcing ribs 10 arranged at intervals. The first reinforcing ribs 9 are arranged perpendicular to the length direction of the original structure beam 1, while the second reinforcing ribs 10 are arranged along the length direction of the original structure beam 1. This structural design aims to enhance the overall stiffness of the anchor plate 3, so that it can more uniformly transfer stress during reinforcement, effectively preventing slippage and failure caused by insufficient local stiffness. The first reinforcing ribs 9 and the second reinforcing ribs 10, through reasonable arrangement spacing and quantity, can provide stable support force under different load conditions, thereby improving the reliability and durability of the entire reinforcement structure.

[0038] Specifically, the first reinforcing ribs 9 are perpendicular to the long side of the original structure beam 1 and are uniformly distributed on the surface of the anchoring plate 3 in the transverse direction. The width and thickness of these ribs can be adjusted according to the actual stress requirements to ensure that they do not deform or buckle when subjected to transverse forces. The second reinforcing ribs 10 are arranged in parallel along the long side direction of the original structure beam 1, serving to enhance the longitudinal stiffness. Similarly, the size and spacing of the second reinforcing ribs 10 also need to be determined according to the specific requirements of the structure. The connection between the first reinforcing ribs 9 and the second reinforcing ribs 10 can be achieved through welding, mechanical fixation, or one-piece molding, etc., to ensure sufficient strength and stability between the two, thereby forming a solid overall structure.

[0039] In actual implementation, high-stiffness materials such as steel plates or other high-strength alloys can be used during the prefabrication of the anchoring plate 3, and the required first reinforcing ribs 9 and second reinforcing ribs 10 can be pre-processed according to the design drawings. After processing is completed, these reinforcing ribs are accurately installed at the predetermined positions, and are firmly combined together by welding to the anchoring plate 3 or using other fixed connection methods. This not only improves the overall stiffness of the anchoring plate 3, but also ensures good cooperation between the parts during subsequent reinforcement construction, thereby achieving the desired reinforcement effect.

[0040] Referring back to Figure 1 In one embodiment, the number of prestressed tension rods 4 of the building structure design beam reinforcement structure of the present application is not less than 4, and these prestressed tension rods 4 are uniformly distributed on the four corners of the anchoring plate 3, ensuring that the pretensioning force of the prestressed tension rods 4 is uniformly distributed, thereby enhancing the stability of the overall structure. The number and layout of the prestressed tension rods 4 are accurately calculated to adapt to different types of original structure beams 1 and external load conditions. Each prestressed tension rod 4 passes through the anchoring plate 3 and is fixed to the original structure beam 1 at both ends through specially designed fixing devices (such as anchors, anchor heads). This design ensures that the anchoring plate 3 and the original structure beam 1 form a close contact, preventing slippage under stress.

[0041] The design of the anchoring plate 3 is also a key part, as it not only provides a basis for installing the prestressed tension rods 4, but also enhances the bonding force between the external reinforcement layer 2 and the original structure beam 1. The anchoring plate 3 is arranged along the length direction of the original structure beam 1 to ensure that the entire reinforcement layer can uniformly bear external loads. In addition, the anchoring plate 3 closely fits the surface of the original structure beam 1 and is tightly combined with the external reinforcement layer 2 through the adhesive layer 5, forming a multi-layer structure that greatly improves the overall stiffness and load-carrying capacity of the reinforced structure.

[0042] Specifically, the prestressed tension rod 4 can be applied with pre-tension force by high-precision tensioning equipment. For example, a tensioning machine is used to tension each prestressed tension rod 4 to ensure that each tension rod is uniformly stressed. During installation, the hole positions at the four corners of the anchoring plate 3 are first accurately marked, then the holes are drilled and the prestressed tension rod 4 is inserted, and the prestressed tension rod 4 is fixed by a special tensioning device. After the prestressed tension rod 4 is fixed, high-performance structural glue is filled between the anchoring plate 3 and the original structure beam 1 to form the adhesive layer 5, and finally the external reinforcing layer 2 is wrapped to complete the installation of the entire reinforcing structure.

[0043] In one embodiment, the adhesive layer 5 of the building structure design beam reinforcing structure of the present application has a thickness of not less than 5 mm and can still maintain stable bonding effect under high or low temperature conditions, ensuring that the bonding strength between the external reinforcing layer 2 and the original structure beam 1 is not affected by the environment. The adhesive layer 5 is located between the external reinforcing layer 2 and the original structure beam 1 and plays an important role in bonding and stress conduction. The thickness design of the adhesive layer 5 not only considers the optimization of mechanical properties, but also considers the applicability under different construction conditions. In addition, the adhesive layer 5 uses high-performance structural glue material, which can provide long-lasting bonding strength under different temperature and humidity environments.

[0044] The specific installation position of the adhesive layer 5 is at the interface between the original structure beam 1 and the external reinforcing layer 2, ensuring that the two are tightly connected. In order to ensure the uniform distribution and sufficient thickness of the adhesive layer 5, a special glue spreading tool such as a spatula or an airbrush can be used to evenly spread a layer of high-performance structural glue with a thickness of not less than 5 mm on the surface of the original structure beam 1. During the spreading process of the adhesive layer 5, special attention should be paid to avoid the generation of air bubbles to ensure the quality of the adhesive layer 5. After the adhesive layer 5 is preliminarily cured, the external reinforcing layer 2 is installed in place, and a special pressing plate and clamp are used to firmly press the external reinforcing layer 2 on the original structure beam 1 to ensure that the adhesive layer 5 fully plays its role. In addition, in order to further enhance the bonding effect, the surfaces of the external reinforcing layer 2 and the original structure beam 1 can be appropriately roughened to increase the contact area and bonding strength between the two. Specifically, a grinding wheel or sandpaper can be used to polish the surface to a certain roughness requirement. This not only helps to improve the adhesion of the adhesive layer 5, but also reduces the slip of the interface layer to ensure the overall stability and reliability of the reinforcing structure.

[0045] In one embodiment, the building structure design beam reinforcing structure of the present application includes a original structure beam 1, an external reinforcing layer 2 wrapping the original structure beam 1, an anchor plate 3 arranged in the external reinforcing layer 2 along the length direction of the original structure beam 1, and a prestressed tension rod 4 passing through the anchor plate 3 and fixed on the original structure beam 1. In order to enhance the bonding effect between the external reinforcing layer 2 and the original structure beam 1, a layer of high-performance structural adhesive layer 5 is arranged between them. This adhesive material can maintain high bonding strength under different temperature and humidity conditions, thereby ensuring the reliability and long-term stability of the reinforcing effect.

[0046] As shown in Figure 4 , the anchor plate 3 in this structure is designed with anti-slip grooves 11 on the contact surface with the original structure beam 1. The depth of these anti-slip grooves 11 is strictly controlled, with a minimum of 2 millimeters, in order to significantly increase the friction between the two by increasing the surface roughness. The design of anti-slip grooves 11 not only enhances the mechanical interlocking effect in local areas, but also effectively prevents the relative sliding of the anchor plate 3 and the surface of the original structure beam 1 when subjected to large loads or external forces. Anti-slip grooves 11 can be manufactured on the surface of the anchor plate 3 using laser cutting or mechanical processing, and appropriate shapes and spacing can be selected according to actual application scenarios to achieve optimal reinforcing effect. For example, in cases requiring particularly high durability, the number and depth of anti-slip grooves 11 can be appropriately increased, while considering construction convenience and cost effectiveness, the layout of anti-slip grooves 11 needs to be reasonably optimized. Specifically, during actual installation, the surface of the original structure beam 1 is first cleaned and pretreated as necessary, then the anchor plate 3 with anti-slip grooves 11 is accurately placed according to the design drawing, and the prestressed tension rod 4 is accurately perforated and firmly fixed in the specified position.

[0047] In one embodiment, the prestressed tension rod 4 of the building structure design beam reinforcing structure of the present application is wrapped with a corrosion-resistant sleeve 12 (see Figure 1 ). The corrosion-resistant sleeve 12 is made of polyethylene material, which has excellent weather resistance and chemical stability, and can effectively resist environmental corrosion factors such as salt spray, acid rain, etc., prolonging the service life of the prestressed tension rod 4. The design of the corrosion-resistant sleeve 12 not only protects the prestressed tension rod 4 from environmental factors, but also ensures the stability of its pre-tensioning force during long-term use, thereby ensuring the effectiveness and reliability of the entire reinforcing structure.

[0048] The prestressed rod 4 is arranged inside the anchoring plate 3 and is fixed on the original structure beam 1 by the end fixing part, and the anticorrosion sleeve 12 is wrapped on the outer surface of the entire prestressed rod 4. In order to ensure the close combination between the anticorrosion sleeve 12 and the prestressed rod 4, appropriate sealing measures can be adopted, such as adding sealing washers at both ends of the anticorrosion sleeve 12 or adopting a heat-shrinkable sleeve technology. In addition, the anticorrosion sleeve 12 can also be provided with longitudinal cuts or pores to facilitate the discharge of air during construction, ensuring that there is no cavity or bubble inside, and further improving the anticorrosion effect. In this way, the prestressed rod 4 will not be affected by the changes of the external environment in the long-term working state, thereby ensuring the overall safety of the reinforced structure.

[0049] For example, in an actual engineering case, the anticorrosion sleeve 12 can be pre-installed on the prestressed rod 4, and then the prestressed rod 4 is inserted into the pre-drilled holes in the anchoring plate 3 and the original structure beam 1. During installation, it is necessary to ensure that the position of the anticorrosion sleeve 12 is correct, and appropriate sealing measures are added at both ends to prevent moisture and corrosive substances from entering the inside of the sleeve. In this way, not only can the prestressed rod 4 be effectively protected, but also the stability and long-term effectiveness of the entire reinforcement system can be ensured.

[0050] In one embodiment, the width of the outer reinforcement layer 2 in the building structure design beam reinforcement structure of the present application is greater than the width of the original structure beam 1. This design not only ensures the effective wrapping of the outer reinforcement layer 2 on the original structure beam 1, but also to some extent reduces the direct impact of external loads on the original structure beam 1, thereby further improving the reinforcement effect of the overall structure. The increase in the width of the outer reinforcement layer 2 makes the edge part of the outer reinforcement layer 2 exceed the edge of the original structure beam 1, thereby providing a wider protection area. This design can better resist the erosion of external environmental factors such as wind pressure, rainwater, etc. on the original structure beam 1.

[0051] For example, in the specific implementation process, the actual width of the original structure beam 1 can be measured first, and then an appropriate width of the outer reinforcement material is selected based on this, so that the outer reinforcement layer 2 can completely cover the original structure beam 1 after installation, and the two ends exceed a certain distance. This additional width can be achieved by cutting the outer reinforcement material or selecting appropriate prefabricated components. The adhesive layer 5 between the outer reinforcement layer 2 and the original structure beam 1 also needs to be adjusted in size to adapt to the new size of the outer reinforcement layer 2, ensuring the firm combination between the two.

[0052] In one embodiment, the adhesive layer 5 of the beam reinforcement structure of the building structure design of the present application uses a two-component reactive structural adhesive. The adhesive layer 5 is located between the original structure beam 1 and the external reinforcement layer 2, which can effectively enhance the bonding strength of the two, and ensure the integrity of the structure. The two-component reactive structural adhesive is formed by the chemical reaction of two chemicals after mixing, thereby forming a high molecular polymer in a solid state. This structural adhesive has high strength and excellent toughness and weather resistance, and can maintain good performance for a long time under different temperature and humidity and climate conditions, avoiding structural slip or failure due to aging of the adhesive layer 5.

[0053] Specifically, the chemical composition of the two-component reactive structural adhesive usually includes resin and hardener, which are mixed uniformly in a certain proportion during construction and then applied to the surface of the original structure beam 1, and then the external reinforcement layer 2 is laid to form a firm bond through physical and chemical effects. Because the adhesive layer 5 has excellent physical and chemical properties such as aging resistance, corrosion resistance and fatigue resistance, it can significantly improve the stability and service life of the reinforced structure.

[0054] In order to ensure the performance of the adhesive layer 5, the surface of the original structure beam 1 needs to be properly cleaned and treated before construction to remove dust, oil stains and other impurities. For example, the surface can be treated by sandblasting or grinding to increase the surface roughness, thereby enhancing the adhesion of the adhesive. Before applying the adhesive layer 5, a primer material can also be used to further enhance the interfacial adhesion. When applying the adhesive layer 5, the thickness should be uniform to avoid bubbles and voids, and to ensure that the adhesive layer 5 completely fills the gap between the original structure beam 1 and the external reinforcement layer 2. The temperature and humidity conditions should be controlled during the curing process to achieve the best chemical crosslinking effect.

[0055] In one embodiment, the surface of the anchor plate 3 of the beam reinforcement structure of the building structure design of the present application is roughened. The roughening method can be mechanical processing, chemical corrosion, sandblasting or electroplating, etc. These roughening methods can significantly change the micro-topography of the surface of the anchor plate 3, so that the surface roughness Ra value is not less than 6 μm. The surface roughening treatment of the anchor plate 3 can increase the physical bonding area between the anchor plate 3 and the original structure beam 1 and the external reinforcement layer 2, thereby enhancing the bonding performance. The roughening treatment not only can improve the bonding force between the anchor plate 3 and the adhesive layer 5, but also can improve the mechanical engagement force between the anchor plate 3 and the prestressed tension rod 4, thereby making the entire reinforced structure more stable and reliable.

[0056] The installation position of the anchoring plate 3 is usually arranged along the length direction of the original structure beam 1, which can be fixed on the original structure beam 1 by spot welding, bolt fixing or pre-stressed rod 4 perforation fixing and the like. Specifically, in one embodiment, the anchoring plate 3 can be fixed on the original structure beam 1 by perforation and welding of the pre-stressed rod 4, so as to ensure the close contact between the anchoring plate 3 and the original structure beam 1. After the pre-stressed rod 4 passes through the anchoring plate 3, it is tensioned and fixed at both ends of the original structure beam 1, so that the anchoring plate 3 and the original structure beam 1 form a pre-pressing state. In addition, the anchoring plate 3 can also use multiple fixing points to disperse the stress, further improving its stability and reliability.

[0057] Specifically, the surface of the anchoring plate 3 can be roughened during construction, for example, the surface of the anchoring plate 3 is formed with fine concave-convex by sand blasting process, so as to achieve the required roughness Ra value of not less than 6 μm. Subsequently, the treated anchoring plate 3 is installed on the original structure beam 1 and fixed by the pre-stressed rod 4. During the fixing process, it is necessary to ensure that the pre-stressed rod 4 is uniformly distributed on the anchoring plate 3, so as to achieve uniform pre-tensioning force. In addition, high-performance structural glue can be applied between the anchoring plate 3 and the original structure beam 1, further enhancing the bonding effect.

[0058] In one embodiment, the connecting part of the pre-stressed rod 4 and the anchoring plate 3 in the building structure design beam reinforcing structure of the present application is provided with an elastic gasket 13 (see Figure 1 ). The elastic gasket 13 is made of high-density sponge rubber material, which has good shock absorption and compensation function for the tension change of the pre-stressed rod 4. Specifically, the elastic gasket 13 is located between the contact surface of the pre-stressed rod 4 and the anchoring plate 3, which can effectively absorb and disperse the impact force generated under dynamic load or vibration conditions, reduce the structural damage caused by stress concentration, and improve the dynamic stability of the entire reinforcing structure.

[0059] Further, the elastic gasket 13 not only has excellent elasticity and toughness, but also has high wear resistance and aging resistance, which can maintain stable mechanical properties during long-term use. In addition, since the high-density sponge rubber has good self-sealing properties, it can automatically recover to its original state within a certain range, effectively compensating for the expansion and contraction of the pre-stressed rod 4 under different use conditions, and ensuring that it is always in the best working state. The design of the elastic gasket 13 also makes the connection between the pre-stressed rod 4 and the anchoring plate 3 more closely and stably during construction and installation, improving the convenience and safety of installation.

[0060] To ensure the reliability and effectiveness of the elastic gasket 13, in practical engineering applications, the thickness and material parameters of the elastic gasket 13 can be precisely controlled to adapt to different design requirements. For example, a suitable sponge rubber density can be selected based on the tension of the prestressed tie rod 4 and the expected environmental conditions to ensure that the elastic gasket 13 can fully exert its shock absorption function while providing the necessary support. In addition, an anti-slip coating can be added to the surface of the elastic gasket 13 to further enhance the friction between it and the prestressed tie rod 4 and the anchor plate 3, preventing relative slippage during long-term use.

[0061] In one embodiment, such as Figure 5 As shown, the adhesive layer 5 of the beam reinforcement structure in this application is specially designed with a reinforcing fiber mesh 14 to further improve the mechanical properties of the adhesive layer 5. The reinforcing fiber mesh 14 is woven from carbon fiber and has a thickness of not less than 1 mm. This reinforcing fiber mesh 14 has high tensile strength and modulus, which can effectively disperse stress and avoid material fatigue or fracture caused by stress concentration. In addition, the reinforcing fiber mesh 14 also has excellent corrosion resistance, which can maintain its physical properties in harsh environments and extend the service life of the reinforced structure. After the reinforcing fiber mesh 14 is embedded in the adhesive layer 5, it not only improves the overall strength of the adhesive layer 5, but also enhances the bonding stability between the outer reinforcement layer 2 and the original structural beam 1.

[0062] Specifically, the reinforcing fiber mesh 14 is woven from continuous carbon fiber filaments in a cross-woven mesh structure. This structure allows the reinforcing fiber mesh 14 to provide balanced mechanical support in all directions, ensuring that no significant deformation or slippage occurs under stress. Simultaneously, the rough surface of the reinforcing fiber mesh 14 increases the contact area with the adhesive layer 5, thereby improving the adhesive bonding effect. During installation, a primer is first applied to the surface of the original structural beam 1, followed by the laying of the reinforcing fiber mesh 14, and then the adhesive layer 5 is covered on its surface, ultimately forming a composite reinforcement layer. The adhesive layer 5 should be a high-performance structural adhesive to ensure good bonding performance under different temperature and humidity conditions, ensuring the stability and reliability of the overall reinforced structure.

[0063] For example, in practical applications, the original structural beam 1 can be prepared in advance at the construction site. Then, a primer is applied to its outer side, the reinforcing fiber mesh 14 is attached, a layer of adhesive is applied, and the entire outer reinforcement layer 2 is fixed on top. This multi-step installation method ensures the accurate positioning and full integration of the reinforcing fiber mesh 14 within the adhesive layer 5, thereby achieving a tight connection between the outer reinforcement layer 2 and the original structural beam 1. During this process, the prestressed tie rod 4 can be further pre-tensioned by fixing the anchor plate 3, ensuring the robustness and stability of the entire reinforcement system.

[0064] In actual operation, when the device is used, first, the surface of the original structure beam 1 is cleaned and polished to ensure that it is flat and clean, providing a good foundation for subsequent reinforcement. Then, a layer of high-performance structural glue is laid as the adhesive layer 5, which can maintain excellent bonding performance under different temperature and humidity conditions. After that, the outer reinforcing layer 2 is carefully wrapped outside the original structure beam 1, further enhancing its overall load-bearing capacity and durability. The outer structure of the outer reinforcing layer 2 is tightly combined with the inner original structure beam 1 through the adhesive layer 5, forming a firm whole. Subsequently, the anchor plate 3 is installed inside the outer reinforcing layer 2 according to the length direction of the original structure beam 1. The presence of the anchor plate 3 enhances the bonding force between the outer reinforcing layer 2 and the original structure beam 1, preventing slipping between the two. The prestressed tension rod 4 passes through the anchor plate 3 and is fixed on the original structure beam 1, using the pre-tensioning force to make the anchor plate 3 and the original structure beam 1 come into close contact, and then make the entire reinforced structure more solid and reliable. Under the joint action of the anchor plate 3 and the prestressed tension rod 4, the bonding force between the outer reinforcing layer 2 and the original structure beam 1 can be evenly distributed, ensuring that there is no local slipping or failure problem during the entire stress process, and finally achieving effective reinforcement and long-term protection of the original structure beam 1.
