Description

Technical Field

[0001] This application relates to the technical field of photovoltaic support systems, and in particular to a photovoltaic support structure for a saddle-shaped roof. Background Technology

[0002] Prestressed concrete saddle-shaped shell panels (referred to as saddle panels) are hollow, thin-walled structures that integrate panels and frames. They are formed using bidirectional spatial prestressing technology and have a wavy, saddle-shaped appearance. Due to their advantages of large span and light weight, they are widely used in the roofs of large-span buildings such as industrial plants. When installing photovoltaic (PV) systems on saddle-shaped roofs, the continuous arc-shaped convexity of the roof makes traditional planar PV bracket installation structures unsuitable. Forcibly fixing the brackets by welding or drilling can easily damage the structural integrity of the saddle panel itself, leading to a decrease in the roof's load-bearing capacity and even causing roof deformation, cracking, and other safety hazards. Furthermore, to improve the waterproofing of connections, simple gaskets are often used for sealing, allowing rainwater to easily seep into the roof interior through the joints, causing moisture damage to the roof insulation layer and corrosion of the steel structure, thus shortening the lifespan of both the building and the PV system. Utility Model Content To address the issue that fixing photovoltaic brackets to saddle-shaped roofs via welding or drilling can easily damage the structural integrity of the saddle-shaped roof and allow rainwater to seep into the roof through the connection gaps, this application provides a photovoltaic bracket structure for saddle-shaped roofs.

[0003] This application provides a photovoltaic support structure for a saddle-shaped roof, which adopts the following technical solution: A photovoltaic support structure for a saddle-shaped roof includes multiple first saddle-shaped bodies and multiple second saddle-shaped bodies. The second saddle-shaped bodies are provided on both sides of the first saddle-shaped bodies, and a connecting component for installing the photovoltaic support is provided between the first saddle-shaped bodies and the second saddle-shaped bodies. The connecting assembly includes a pre-embedded steel plate, a channel steel, a waterproof component, and a light-transmitting cover. One end of the pre-embedded steel plate is installed at one end of the first saddle plate body, and the other end is set at one end of the second saddle plate body, connecting the first saddle plate body to the second saddle plate body. The channel steel is set on the side of the pre-embedded steel plate away from the first saddle plate body. One side of the channel steel is provided with a first connector connected to the first saddle plate body, and the other side is installed with a second connector connected to the second saddle plate body. The light-transmitting cover is placed over the side of the channel steel away from the first saddle plate body. The waterproof component is adhered to the bottom of the first saddle plate body, the bottom of the second saddle plate body, the bottom of the pre-embedded steel plate, and the bottom of the channel steel.

[0004] By adopting the above technical solution, the combination and arrangement of the first saddle plate body and the second saddle plate body form a continuous arc-shaped protrusion structure of the saddle plate roof; the connecting component uses a pre-embedded steel plate to achieve a stable connection between adjacent first and second saddle plate bodies, while providing an installation foundation for the channel steel. The channel steel serves as a direct installation carrier for the photovoltaic bracket, eliminating the need for welding or drilling on the saddle plate body, effectively protecting the structural integrity of the saddle plate body and preventing a decrease in the roof's load-bearing capacity or cracking; the bottom waterproof component blocks rainwater from seeping in through the connection nodes, and the top skylight cover not only prevents the channel steel and connecting components from being eroded by rainwater, but also retains the roof's lighting function, thus achieving the overall effect of adapting the photovoltaic bracket to the arc-shaped saddle plate roof, providing structural protection, and achieving waterproofing and lighting.

[0005] Optionally, the bottom of the first saddle plate body, the bottom of the second saddle plate body, the bottom of the embedded steel plate, and the bottom of the channel steel are all bonded to the waterproof component with structural adhesive, so that the bottom of the first saddle plate body, the bottom of the second saddle plate body, the bottom of the embedded steel plate, and the bottom of the channel steel are integrally sealed. By adopting the above technical solution, the structural adhesive has high-strength adhesion and sealing properties, which can make the waterproof components fit tightly to the bottom of each component, eliminate gaps between components, replace the traditional simple gasket seal, and prevent rainwater from seeping in from the splicing gap between the saddle plate and the connecting components. Optionally, the waterproof component is made of carbon fiber cloth. By adopting the above technical solutions, carbon fiber cloth has the characteristics of high strength, corrosion resistance and aging resistance, and can better adapt to the slight deformation of saddle roof (such as the deflection change caused by prestress relaxation), and is not prone to warping or cracking; at the same time, carbon fiber cloth has strong weather resistance and can maintain stable waterproof performance in the environment of sun exposure, rain, and alternating high and low temperatures, reducing the frequency and cost of later waterproof maintenance. Optionally, the channel steel is provided with mounting holes for the photovoltaic bracket to pass through. By adopting the above technical solution, the mounting holes provide installation positions for the columns in the photovoltaic bracket, eliminating the need to drill holes in the channel steel on site, thus avoiding damage to the structural strength of the channel steel, and ensuring the consistency of the photovoltaic bracket installation position each time. Optionally, both the channel steel and the embedded steel plate are provided with a first positioning threaded hole on one side and a second positioning threaded hole on the other side. The first connector passes through the first positioning threaded hole and is connected to the first saddle plate body, and the second connector passes through the second positioning threaded hole and is connected to the second saddle plate body. By adopting the above technical solution, the positioning threaded hole provides precise positioning for the first and second connectors, ensuring that the connection position of the channel steel with the embedded steel plate and the saddle plate body is fixed, avoiding uneven force caused by connection offset; the threaded connection method is easy to install and disassemble, and if maintenance or replacement of parts is required in the future, there is no need to damage the overall structure, reducing maintenance difficulty; at the same time, the threaded connection has strong self-locking ability, which can enhance the anti-loosening ability of the connection node and improve the stability of the structure under wind and snow loads.

[0006] Optionally, the light-transmitting cover is arc-shaped, with one side of the light-transmitting cover covering the first saddle plate body and the other side covering the second saddle plate body. By adopting the above technical solution, the arc-shaped skylight cover is adapted to the wavy arc of the saddle roof. The skylight cover spans the two saddle roof bodies and can completely cover the channel steel and connecting components in the middle, minimizing the direct contact of rainwater with the connecting parts. At the same time, the arc-shaped surface is conducive to rainwater diversion, preventing rainwater from accumulating on the surface of the cover and reducing the risk of rainwater infiltration. In addition, the arc-shaped structure can withstand a certain load and extend the service life of the skylight cover. Optionally, a first auxiliary component is connected between the first saddle plate body and one end of the light-transmitting cover, and a second auxiliary component is connected between the second saddle plate body and the other end of the light-transmitting cover.

[0007] By adopting the above technical solution, the first auxiliary component and the second auxiliary component fix the skylight cover from both sides, preventing the skylight cover from being overturned or displaced by wind force, thus enhancing the stability of the cover installation. At the same time, the auxiliary components can disperse the pressure of the skylight cover on the saddle plate body, preventing the edge of the cover from pressing on the saddle plate for a long time, which would lead to local cracking and protect the structural integrity of the saddle plate. In addition, the auxiliary components can also fine adjust the installation angle of the skylight cover to ensure that the cover plate fits perfectly with the roof curvature, further improving the sealing and air diversion effect. Optionally, the first auxiliary component includes a first support base, which is bonded to the first saddle plate body. A first auxiliary ring is rotatably mounted on the first support base. A first connecting ring is mounted on one end of the light-transmitting cover. A first auxiliary rope is connected to the first auxiliary ring, and the other end of the first auxiliary rope is connected to the first connecting ring. The second auxiliary component includes a second support base, which is adhered to the second saddle plate body. A second auxiliary ring is rotatably mounted on the second support base. A second connecting ring is mounted on the other end of the light-transmitting cover. A second auxiliary rope is connected to the second auxiliary ring, and the other end of the second auxiliary rope is connected to the second connecting ring. By adopting the above technical solution, the first support and the second support are fixed by bonding, eliminating the need to drill holes in the corresponding saddle plate body and protecting the structural integrity; the rotation setting of the auxiliary ring allows the auxiliary rope to adjust its angle according to the slight deformation of the skylight cover, avoiding damage to the cover or saddle plate due to rigid tension of the auxiliary rope; the flexible connection of the auxiliary rope can provide stable tension to fix the cover plate, and also buffer the impact of external forces on the cover plate, reducing structural stress concentration. At the same time, the rope structure is lightweight and will not add too much load, taking into account both the fixing effect and the lightweight roof requirements.

[0008] In summary, this application includes at least one of the following beneficial technical effects: 1. This structure uses pre-embedded steel plates and channel steel to connect the photovoltaic brackets and the curved saddle roof, without damaging the saddle roof structure. This effectively protects the bidirectional prestressed system and the hollow thin-walled characteristics, preventing the roof's load-bearing capacity from decreasing or cracking. At the same time, the bottom waterproof component and the curved skylight cover form a double waterproof layer, solving the problem of water leakage caused by traditional gasket sealing and extending the life of the building and the photovoltaic system. 2. By combining the arc-shaped skylight cover with auxiliary components, the roof's lighting function is preserved while achieving waterproof protection, solving the problem of traditional photovoltaic brackets blocking the skylight strip and meeting the natural lighting needs of industrial plants and other buildings.

[0014] The following is in conjunction with the appendix Figure 1 and Figure 2 This application will be described in further detail.

[0015] This application discloses a photovoltaic support structure for a saddle-shaped roof, referring to... Figure 1 The photovoltaic support structure of the saddle roof includes multiple first saddle body 1 and multiple second saddle body 2. The second saddle body 2 is provided on both sides of the first saddle body 1. A connecting component 3 for installing the photovoltaic support 6 is provided between the first saddle body 1 and the second saddle body 2. The connecting assembly 3 includes a pre-embedded steel plate 31, a channel steel 32, a waterproof component 33, and a light-transmitting cover 34. One end of the pre-embedded steel plate 31 is installed at one end of the first saddle plate body 1, and the other end is set at one end of the second saddle plate body 2 to connect the first saddle plate body 1 to the second saddle plate body 2. The channel steel 32 is set on the side of the pre-embedded steel plate 31 away from the first saddle plate body 1. One side of the channel steel 32 is provided with a first connector 35 connected to the first saddle plate body 1, and the other side is installed with a second connector 36 connected to the second saddle plate body 2. The light-transmitting cover 34 covers the side of the channel steel 32 away from the first saddle plate body 1. The waterproof component 33 is bonded to the bottom of the first saddle plate body 1, the bottom of the second saddle plate body 2, the bottom of the pre-embedded steel plate 31, and the bottom of the channel steel 32.

[0016] In this structure, the first saddle plate body 1 and the second saddle plate body 2 are the basic load-bearing components. Multiple sets are connected in sequence to form a continuous saddle plate roof system, providing a stable carrier for the installation of the photovoltaic bracket 6. The pre-embedded steel plate 31 in the connecting component 3 can realize the structural connection of adjacent saddle plate bodies to form a continuous roof load-bearing whole. At the same time, the pre-embedded steel plate 31 also provides an installation foundation for the channel steel 32. Through its own planar structure, it supports the channel steel 32, so that the channel steel 32 can be stably fixed above the saddle plate roof, avoiding the installation instability problem caused by the channel steel 32 directly contacting the curved saddle plate body.

[0017] Furthermore, the channel steel 32 also serves as a direct mounting carrier for the photovoltaic bracket 6, bearing the weight of the photovoltaic bracket 6 and transferring the load to the embedded steel plate 31. The load is then distributed to the first saddle plate body 1 and the second saddle plate body 2 via the embedded steel plate 31, preventing structural damage to the saddle plate body caused by localized stress concentration. By providing an installation reference for the photovoltaic bracket 6 through the channel steel 32, the problem of traditional flat brackets being unable to adapt to the curved roof surface of the saddle plate is solved. This allows the photovoltaic bracket 6 to achieve indirect leveling installation through the channel steel 32, ensuring the flatness of the photovoltaic array and thus improving the power generation efficiency of the photovoltaic panels.

[0018] The first connector 35 passes through the positioning structure of the channel steel 32 and the embedded steel plate 31, fixing the channel steel 32 to the first saddle plate body 1. Similarly, the second connector 36 fixes the channel steel 32 to the second saddle plate body 2, strengthening the connection between the channel steel 32 and the roof. This helps the embedded steel plate 31 further transfer the photovoltaic load borne by the channel steel 32 to the saddle plate body, avoiding load concentration on a single connection surface of the embedded steel plate 31, and ensuring the stability of the channel steel 32 under wind and snow loads. Both the first connector 35 and the second connector 36 adopt detachable connection methods, such as bolt connections, which facilitates the maintenance, adjustment, or replacement of the photovoltaic bracket 6 in the future without damaging the saddle plate body and the embedded steel plate 31.

[0019] Waterproof component 33 covers the bottom of the first saddle plate body 1, the bottom of the second saddle plate body 2, the bottom of the embedded steel plate 31, and the bottom of the channel steel 32, forming a continuous bottom waterproof barrier. This seals the gaps at the joints of the components, preventing rainwater from seeping into the roof from the connection nodes and improving the reliability of the roof's waterproofing. Skylight cover 34 covers the connection areas of the connecting component 3 with the first saddle plate body 1 and the second saddle plate body 2, forming external protection for the channel steel 32, the first connector 35, the second connector 36, and other connecting components. This protects the internal components from direct erosion by rainwater, dust, and ultraviolet rays, ensuring the long-term stable operation of the connecting component 3. Simultaneously, it accommodates the lighting needs of the space below the roof, avoiding insufficient roof lighting caused by the installation of the photovoltaic bracket 6.

[0020] The photovoltaic support structure of this saddle-shaped roof achieves the compatible installation of the photovoltaic support 6 and the curved saddle-shaped roof through the connection of the saddle-shaped roof body and the connecting components 3. Specifically, a continuous roof support system is formed based on the first saddle-shaped roof body 1 and the second saddle-shaped roof body 2. The pre-embedded steel plate 31 achieves a non-damaging connection between adjacent saddle-shaped roof bodies, ensuring the original load-bearing capacity of the roof and avoiding problems such as roof deformation and cracking. This solves the problem of forced fixing damaging the structure. The channel steel 32 serves as the installation carrier for the photovoltaic support 6. In conjunction with the waterproof component 33 and the light-transmitting cover plate 34, the waterproof, protection and light-transmitting problems are solved. This solves the problem of easy leakage of traditional gasket sealing and avoids the problem of moisture in the insulation layer and corrosion of the steel structure caused by rainwater infiltration. It extends the service life of the building and the photovoltaic system. This structure can meet the photovoltaic installation requirements of large-span saddle-shaped roofs.

[0021] The bottoms of the first saddle plate body 1, the second saddle plate body 2, the embedded steel plate 31, and the channel steel 32 are all bonded to the waterproof component 33 using structural adhesive, creating a unified, sealed system. The structural adhesive acts as a bonding medium, filling the tiny gaps between the waterproof component 33 and the surfaces of the bottoms of the first saddle plate body 1, the second saddle plate body 2, the embedded steel plate 31, and the channel steel 32, further enhancing the sealing effect. This ensures that the waterproof component 33 remains firmly in place with the surfaces of all components, achieving a complete seal at the bottom of the roof. This eliminates gaps and dead angles that are common with traditional single-gasket seals, preventing moisture from seeping in through the bonding interface between the waterproof component 33 and the components. This ensures the long-term load-bearing capacity of the first saddle plate body 1, the second saddle plate body 2, the embedded steel plate 31, and the channel steel 32. Simultaneously, it strengthens the connection between the waterproof component 33 and the components, resisting the impact of the external environment on the waterproof structure and extending the service life of the waterproof system.

[0022] In this application, the waterproof component 33 is made of carbon fiber cloth. Carbon fiber cloth has a tight fiber structure and excellent adhesion, effectively preventing rainwater and moisture from seeping into the structure, avoiding substrate corrosion, mold growth, or structural strength reduction due to moisture intrusion, and ensuring a dry environment at the bottom of the entire roof photovoltaic support structure 6. Simultaneously, its flexible nature allows it to conform to the surface shapes of different components, filling tiny gaps between components and ensuring a continuous and complete waterproof layer even at curved surfaces and joints where gaps are prone to occur, eliminating any waterproof dead spots. While achieving waterproofing, the carbon fiber cloth itself has high tensile strength and corrosion resistance, which helps enhance the structural stability of the covered component surface, resisting external environmental pull or compression on the waterproof structure, preventing damage to the waterproof layer due to external forces, and further enhancing the durability and stability of the entire structure's bottom.

[0023] Both the channel steel 32 and the embedded steel plate 31 have a first positioning threaded hole on one side and a second positioning threaded hole on the other side. The first connecting piece 35 passes through the first positioning threaded hole and connects to the first saddle plate body 1, and the second connecting piece 36 passes through the second positioning threaded hole and connects to the second saddle plate body 2. The first positioning threaded hole provides a precise connection position on the same side of the channel steel 32 and the embedded steel plate 31, providing a suitable threaded interface for the insertion and fixing of the first connecting piece 35, limiting the radial and axial displacement of the first connecting piece 35 after installation, ensuring the stability of the connection relationship, realizing the precise docking of the first connecting piece 35 with the channel steel 32 and the embedded steel plate 31, ensuring that the first connecting piece 35 evenly transmits the load, and ensuring the stability of the connection structure.

[0024] The second positioning threaded hole and the first positioning threaded hole form a symmetrical connection reference on opposite sides of the channel steel 32 and the embedded steel plate 31, providing a precise installation position and threaded interface for the second connector 36. This allows the second connector 36 to accurately mate with the second saddle plate body 2, and together with the first positioning threaded hole, constructs a bidirectional symmetrical connection structure. This ensures that the load is evenly transferred to the saddle plate body through the connectors on both sides, preventing tilting or deformation of components caused by unilateral force and improving balance and stability. The detachable nature of the threaded fit facilitates subsequent maintenance or adjustment of the connection structure without damaging the channel steel 32, the embedded steel plate 31, or the first saddle plate body 1 and the second saddle plate body 2.

[0025] In this application, the skylight cover 34 is arc-shaped, with one side covering the first saddle plate body 1 and the other side covering the second saddle plate body 2. The arc-shaped skylight cover 34 adapts to the arc-shaped contour of the saddle plate roof through its arc structure, covering the outer side of the channel steel 32 and the connecting nodes, preventing rainwater, dust, and impurities from directly eroding the internal components. The arc shape can disperse external loads, such as snow accumulation and wind pressure, reducing the impact of concentrated loads on itself and the components below. The arc-shaped surface is not prone to water and dust accumulation, reducing corrosion or structural pressure caused by accumulated materials. At the same time, the arc-shaped skylight cover 34 transmits natural light to the space below the roof through its own light transmission characteristics, thus having both protective and lighting functions.

[0026] refer to Figure 1 and Figure 2 A first auxiliary component 4 connects the first saddle plate body 1 to one end of the skylight cover 34, and a second auxiliary component 5 connects the second saddle plate body 2 to the other end of the skylight cover 34. The first auxiliary component 4 provides additional support to one end of the skylight cover 34 through its own structure, transferring and dispersing the external load borne by that end of the skylight cover 34, smoothly transmitting the load to the first saddle plate body 1, preventing the load from directly acting on the overlap between the skylight cover 34 and the saddle plate body, and ensuring structural integrity. Simultaneously, it assists in adjusting the installation angle and position of the skylight cover 34 to ensure a tight fit with the first saddle plate body 1, ensuring that rainwater can penetrate the interior.

[0027] The second auxiliary component 5 symmetrically cooperates with the first auxiliary component 4, forming a support and connection between the second saddle plate body 2 and the other end of the skylight cover 34. It helps to fix the position of the other end of the skylight cover 34, adjusts its fit with the second saddle plate body 2, ensures the overall flatness of the skylight cover 34, avoids tilting due to uneven support on both sides, and prevents displacement or warping due to loose fit. This reduces the risk of rainwater seepage from the joint. Simultaneously, the symmetrical support ensures the overall flatness of the skylight cover 34, complete protection range, and no blind spots. The second auxiliary component 5 can also bear the load of the other end of the skylight cover 34 and distribute the load to the second saddle plate body 2, working with the first auxiliary component 4 to balance the external forces borne by the skylight cover 34, preventing structural deformation or connection failure due to excessive load on one side, and ensuring the structural safety of the photovoltaic roof system.

[0028] The first auxiliary component 4 includes a first support base 41, which is bonded to the first saddle plate body 1. A first auxiliary ring 42 is rotatably mounted on the first support base 41. A first connecting ring 43 is mounted on one end of the skylight cover 34. A first auxiliary rope 44 is connected to the first auxiliary ring 42, and the other end of the first auxiliary rope 44 is connected to the first connecting ring 43. The first support base 41 is fixed to the first saddle plate body 1 by bonding, providing a stable mounting base for the first auxiliary ring 42 and ensuring that the entire auxiliary component is reliably connected to the corresponding saddle plate body through the first support base 41. In this application, the bonding method ensures the stability of the connection between the first support base 41 and the first saddle plate body 1 without damaging the prestressed structure and thin-walled characteristics of the first saddle plate body 1, avoiding problems such as reduced roof load-bearing capacity and cracking caused by installation. At the same time, it provides a precise and stable installation reference for the first auxiliary ring 42 and the first auxiliary rope 44.

[0029] The first auxiliary ring 42 can rotate flexibly around the first support base 41, providing an adjustable connection end for the first auxiliary rope 44. This allows the first auxiliary rope 44 to adjust its tension direction according to changes in the installation angle and position of the skylight cover 34 or environmental deformation, preventing excessive tension or slack due to a fixed direction. The first auxiliary ring 42 can transfer the tension of the first auxiliary rope 44 to the first support base 41, while its rotational characteristics buffer the impact of external forces on the first auxiliary rope 44, reducing the risk of breakage due to sudden changes in the direction of force. The first connecting ring 43 provides a clear and stable connection point for the first auxiliary rope 44, dispersing the tension of the first auxiliary rope 44 on the skylight cover 34 and preventing the skylight cover 34 from cracking or deforming due to excessive local stress.

[0030] The first auxiliary rope 44 transfers the load from one end of the skylight cover 34 to the first saddle plate body 1, ensuring that one end of the skylight cover 34 is stably fixed without warping or displacement, thus improving the reliability of sealing and protection. Simultaneously, its flexibility adapts to the arc-shaped connection between the skylight cover 34 and the first saddle plate body 1. The first auxiliary rope 44 can be adjusted in length or tension to fine-tune the installation position and fit of one end of the skylight cover 34, ensuring a seamless connection between the skylight cover 34 and the first saddle plate body 1 and reducing the risk of rainwater leakage.

[0031] The first auxiliary component 4 constructs a flexible and stable connection and support system between the first saddle plate body 1 and one end of the light-transmitting cover plate 34, realizing non-destructive fixation of one end of the light-transmitting cover plate 34, while assisting in adjusting the fit of the light-transmitting cover plate 34, transferring and dispersing the load, and ensuring that the light-transmitting cover plate 34 stably performs its protective and light-transmitting functions.

[0032] The second auxiliary component 5 includes a second support base 51, which is bonded to the second saddle plate body 2. A second auxiliary ring 52 is rotatably mounted on the second support base 51. A second connecting ring 53 is mounted on the other end of the light-transmitting cover 34. A second auxiliary rope 54 is connected to the second auxiliary ring 52, and the other end of the second auxiliary rope 54 is connected to the second connecting ring 53. The second auxiliary component 5 is located at the other end of the second saddle plate body 2 and the light-transmitting cover 34, and has the same function as the first auxiliary component 4. Through the structural combination of the bonding and fixing of the second support base 51, the rotational adjustment of the second auxiliary ring 52, the flexible connection of the second auxiliary rope 54, and the connecting and fixing of the second connecting ring 53, a flexible and stable connection and support system is also constructed between the second saddle plate body 2 and the other end of the light-transmitting cover 34. This achieves non-destructive fixing of the other end of the light-transmitting cover 34, while also assisting in adjusting the fit of the light-transmitting cover 34, transferring and distributing the load, and ensuring that the light-transmitting cover 34 stably performs its protective and light-transmitting functions.

[0033] The channel steel 32 is provided with mounting holes 321 for the photovoltaic support 6 to pass through. The mounting holes 321 provide a preset channel for the insertion and fixation of the columns in the photovoltaic support 6. Through the cooperation between the hole wall and the photovoltaic support 6 or fasteners, the lateral and longitudinal displacement of the photovoltaic support 6 is restricted, ensuring the stability of the installation posture. The path of the mounting holes 321 is designed so that the weight, wind load, snow load, etc. borne by the photovoltaic support 6 can be evenly transferred to the channel steel 32 through the mounting holes 321, avoiding the concentration of load in local areas and reducing the risk of deformation of the channel steel 32 or the photovoltaic support 6.

[0034] The implementation process of a photovoltaic support structure for a saddle-shaped roof according to an embodiment of this application is as follows: One end of the embedded steel plate 31 is attached to the end of the first saddle plate body 1, and the other end is attached to the end of the adjacent second saddle plate body 2, ensuring that the embedded steel plate 31 is placed horizontally and tightly attached to the surface of the saddle plate body. The embedded steel plate 31 is temporarily fixed by non-destructive means (such as structural adhesive for auxiliary fixing or by using the reserved structure on the edge of the saddle plate body), and further reinforced after being connected to the channel steel 32.

[0035] Place the channel steel 32 on the side of the embedded steel plate 31 away from the saddle plate body, adjust the position of the channel steel 32 so that the first positioning threaded hole on the channel steel 32 is aligned with the first positioning threaded hole on the embedded steel plate 31, and the second positioning threaded hole is aligned in the same way; pass the first connecting piece 35 through the aligned first positioning threaded hole and fix it to the first saddle plate body 1, and pass the second connecting piece 36 through the second positioning threaded hole and fix it to the second saddle plate body 2, ensuring that the connecting pieces are tightened so that the channel steel 32, the embedded steel plate 31 and the saddle plate body form a stable connection whole.

[0036] Clean the bottom of the first saddle plate body 1, the bottom of the second saddle plate body 2, the bottom of the embedded steel plate 31, and the bottom of the channel steel 32 to remove oil and impurities, ensuring that the surfaces are dry and flat, so as to provide a good foundation for the bonding of the waterproof component 33.

[0037] Apply high-strength structural adhesive evenly to the bottom of the above components, and tightly adhere the carbon fiber cloth to the surface of the structural adhesive, ensuring that the carbon fiber cloth is wrinkle-free, bubble-free, and covers all joint gaps; seal the edges of the carbon fiber cloth, and apply additional structural adhesive to form a continuous overall waterproof layer. After the structural adhesive has cured, check to ensure that the waterproof performance is reliable.
