Description

Technical Field

[0001] The invention relates to the technical field of curtain wall manufacturing, in particular to a waterscape curtain wall bottom opening structure and an installation method thereof. Background Art

[0002] In the design and construction of the waterscape at the bottom of the curtain wall, most companies still use the traditional method of filling the bottom of the aluminum alloy curtain wall beam with rock wool. This method has poor waterproof sealing at the bottom of the curtain wall, and it is very easy for water to seep into the room from the bottom of the glass beam, causing moisture and water stains on the indoor floor, thus causing damage to the paving surface and wooden floor. If the above problems occur, they need to be repaired and processed continuously, causing a lot of trouble for developers and construction companies.

[0003] For example, patent application No. CN202011557011.1 discloses a water curtain wall, including a base fixed on the ground, a plurality of keel steels are vertically arranged on the upper surface of the base, and reinforcing steel connecting the plurality of keel steels is arranged on the keel steel, a curtain wall body is connected to the keel steel, an installation cavity is reserved between the curtain wall body and the keel steel, and a connecting mechanism connected to the curtain wall body is arranged on the keel steel, a support platform for receiving water flow is arranged on the ground at the bottom of the curtain wall body, a support groove is vertically opened on the upper surface of the support platform, a plurality of through holes penetrating the support groove are vertically opened in the support groove, a water reservoir for storing water is opened on the ground at the bottom of the support groove, the through holes are connected to the water reservoir and the water level is not higher than the upper surface of the bottom plate of the support groove, a submersible pump is arranged in the water reservoir, and the pump is connected to a water supply pipe that allows water to flow down from the curtain wall body.

[0004] The above solution reduces the possibility of corrosion of the bottom of the curtain wall body due to water immersion; however, in this solution, there is still the possibility of leakage, so an optimized solution is urgently needed. Summary of the invention

[0005] In view of the problems of water leakage and seepage at the bottom of the curtain wall near the water in the background technology, the installation structure of the bottom of the curtain wall is reconstructed and a Z-shaped water stop plate is added to ensure the structural stability and long-term durability of the waterscape main body, effectively prevent water seepage in the waterscape, and maintain the beauty and functionality of the curtain wall.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A curtain wall lower opening structure near water, comprising: a waterscape main body, including glass ribs and large glass; Among them, the lower ends of the glass ribs and the large glass are respectively provided with glass rib supporting steel U-grooves and large glass supporting steel U-grooves; wherein, the lower parts of the glass rib supporting steel U-grooves and the large glass supporting steel U-grooves are provided with Z-shaped water stop plates.

[0007] The core of this scheme is to reasonably set up the support and water-stopping structure. That is, the glass ribs and large glass are fixed and supported by the glass rib supporting steel U-grooves and the large glass supporting steel U-grooves, while the Z-type water-stopping plate is responsible for preventing water in the main body of the waterscape from seeping into the room. On the one hand, the edges of the glass ribs and large glass are fixed by combining with the steel U-grooves to ensure the stability of the structure. At the same time, the structural strength of the steel U-grooves is high and can withstand the weight of the glass and the water pressure from the waterscape; on the other hand, the design of the Z-type water-stopping plate can fit closely to the lower mouth of the glass curtain wall to form an effective water-stopping barrier to prevent water penetration. Thus, a good anti-seepage effect is achieved. Through the pre-embedded design of the Z-type water-stopping plate, it is constructed synchronously with the main body of the waterscape to form a sealed waterproof system, which effectively prevents water penetration; secondly, the structural cost is low, the process is simple, and it is easy to operate. Because the production of the Z-type water-stopping plate and the steel U-grooves is relatively simple, no complex technology is required during the installation process, and it can be completed quickly, thereby reducing the construction cost. Technicians in this field can further optimize the material of the Z-type waterstop plate to adapt to water resistance and corrosion resistance under different environmental conditions, or develop a steel U-channel structure that can automatically adjust the contact pressure with the glass ribs and large glass to adapt to different load conditions and temperature changes.

[0008] Preferably, the outer surface of the Z-shaped water stop plate is provided with a corrosion-resistant layer; the side of the Z-shaped water stop plate away from the large glass is provided with a magnetic adsorption layer (11. The magnetic adsorption layer can utilize magnetism to adsorb metal particles or other magnetic substances that may exist in the water body. The metal particles may come from the circulation filtration equipment of the waterscape system, or may be naturally formed due to water quality problems. If these metal particles exist in the water body for a long time, they may be brought to the vicinity of the water stop plate by the action of water flow, waves and other forces, causing wear or blockage to the water stop structure, affecting the anti-leakage effect. The introduction of the magnetic adsorption layer can effectively adsorb metal particles and reduce their potential damage to the water stop plate and other anti-leakage components. The provision of the magnetic layer increases the service life of the water stop plate because it reduces wear and tear, thereby reducing the frequency and cost of maintenance and replacement. The detachable magnetic adsorption layer can be cleaned or replaced regularly to ensure that its adsorption effect continues to be effective.

[0009] Furthermore, the surface of the corrosion-resistant layer is a microporous structure, and the corrosion-resistant layer is made of a hydrophobic material. By forming a microporous structure on the surface of the corrosion-resistant layer, water vapor is allowed to escape. The use of hydrophobic materials further reduces the adhesion of water molecules to the material and reduces the risk of corrosion caused by the penetration of water molecules. When water vapor escapes, it will reduce the condensation of water vapor inside the waterstop plate due to temperature differences, thereby reducing the corrosion problem caused by condensed water. Through the combination of microporous structure and hydrophobic material, not only the durability of the waterstop plate is improved, but also its corrosion resistance is improved. This structural design enables the Z-type waterstop plate to maintain good performance and extend its service life even in a long-term water-immersion environment. Traditional waterstop plates may only focus on their water-stopping function, but ignore the problem of water vapor condensation caused by temperature differences. By introducing microporous structure and hydrophobic material on the surface of the waterstop plate, not only the water-stopping problem is solved, but also the potential corrosion problem caused by water vapor condensation is specifically solved. It is worth noting that the size, shape, and distribution of the micropore structure may need to be optimized through precise calculations and experiments to ensure that water vapor can escape smoothly without causing other problems. At the same time, the formulation and processing of hydrophobic materials may also need to be specifically designed to ensure good performance under various environmental conditions.

[0010] Furthermore, the corrosion-resistant layer is a conductive metal coating, and the corrosion-resistant layer is connected to the grounding system of the curtain wall. This scheme is based on cathodic protection, where the electric current makes the metal a recipient of electrons, thereby reducing the tendency of metal atoms to release electrons (i.e., oxidize). Through the connection of the coating, the waterstop plate becomes a cathode and is protected, reducing corrosion caused by contact with water. The conductive metal coating provides an additional protective layer that can reduce the time the metal substrate is exposed to the corrosive medium. In addition, by connecting to the grounding system, the coating can effectively become part of the cathodic protection of the entire curtain wall system, enhancing the corrosion resistance of the system. By utilizing the principle of cathodic protection, the corrosion resistance of the Z-type waterstop plate can be significantly improved and its service life can be extended. In addition, due to the conductivity of the metal coating, it can also be used to monitor the corrosion condition of the waterstop plate, providing possible monitoring and preventive measures. A more proactive means of corrosion protection is provided by cathodic protection. At the same time, the conductive metal coating can also be used as a monitoring layer, which increases the intelligence and self-diagnosis capabilities of the system.

[0011] Furthermore, flexible rubber pads are provided in the steel U-grooves supporting the glass ribs and the steel U-grooves supporting the large glass. The use of the flexible rubber pads can provide additional buffering effect, reduce the direct contact between the glass and the steel U-grooves caused by factors such as temperature changes, earthquakes, and wind pressure, and prevent the glass from breaking due to improper force. At the same time, the rubber pads can also provide a tighter sealing effect to prevent water penetration.

[0012] Furthermore, the lower mouth of the large glass supporting steel U-groove is filled with a sealing waterproof mortar, and after the sealing waterproof mortar is completely dry, a waterproof layer is applied to the outdoor side. By using sealing waterproof mortar at the lower mouth of the U-groove, a waterproof barrier can be formed in the structure to prevent moisture from directly contacting the external environment through the U-groove. After the mortar is cured, the waterproof layer is applied to further improve the waterproof performance. The waterproof layer not only increases the number of waterproof layers, but also provides an additional protective layer to prevent water leakage caused by aging or damage of the mortar. This method provides a double waterproof measure by directly using waterproof mortar and applying a waterproof layer at the lower mouth of the U-groove. This double-layer protection can effectively prevent water infiltration problems caused by environmental factors (such as wind, rain, and temperature changes), ensuring the long-term stability and durability of the structure. The combined use of sealing waterproof mortar and waterproof layer greatly improves the waterproof ability of the large glass supporting steel U-groove.

[0013] Furthermore, embedded parts are provided below the main body of the waterscape, and the embedded parts are embedded synchronously with the main body of the waterscape, and connected to the large glass supporting steel U-groove through the supporting angle code 2. The embedded parts are embedded together with the main structure of the waterscape during construction, ensuring the stability and consistency of the embedded parts and the main structure, thereby ensuring the stability of the entire curtain wall structure. The embedded parts are connected to the large glass supporting steel U-groove through the supporting angle code 2. Such a design allows the large glass to be directly supported and fixed on the main structure, providing a solution for structural connection. By embedding the embedded parts synchronously with the main structure, the complexity and cost of later construction can be reduced. In addition, the use of embedded parts can improve the overall stability and durability of the structure, because it is directly connected to the main structure, rather than being added later. During the construction process, the synchronous embedding of embedded parts reduces the difficulty and workload of later construction and improves construction efficiency.

[0014] Preferably, the glass rib supporting steel U-groove is connected to the embedded part through a supporting angle code 1. As a connecting element, the supporting angle code 1 can firmly fix the glass rib supporting steel U-groove on the embedded part to form a stable triangular support structure. Through the connection of the supporting angle code 1, the load transmitted by the glass rib is effectively dispersed, ensuring the uniform force of the overall structure. The use of the supporting angle code 1 enhances the strength and reliability of the connection point. The supporting angle code 1 is connected to the glass rib supporting steel U-groove and the embedded part by welding, which not only improves the stability of the connection, but also increases the bearing capacity of the welding point, making the structure more stable. That is: the triangular support structure connected by the supporting angle code 1 increases the stability of the overall structure, especially in a water environment, and can effectively resist the vibration caused by water flow impact or wind. And by optimizing the connection method, the construction efficiency is improved, the dependence on site conditions is reduced, which is conducive to shortening the construction period.

[0015] Preferably, the Z-shaped water stop plate is pre-buried synchronously with the main structure of the waterscape to prevent water in the waterscape from entering the lower opening of the glass curtain wall. The Z-shaped water stop plate is used to prevent water in the waterscape from penetrating into the interior of the curtain wall structure, while ensuring the stability and waterproof performance of the curtain wall structure. By pre-buried Z-shaped water stop plates in the main body of the waterscape during the construction process, the water stop plates become part of the structure. In this way, an effective waterproof barrier is formed in the connection area between the waterscape and the curtain wall to prevent water penetration. The setting of the Z-shaped water stop plate not only provides structural support, but also enhances the overall waterproof performance. The design of the Z-shaped water stop plate can effectively cope with the humidity and pressure changes in the environment around the waterscape, especially when the water level changes greatly. The water stop plate can provide an additional waterproof layer to reduce water erosion of the lower opening of the curtain wall. At the same time, the water stop plate also improves the overall stability of the curtain wall structure and prevents structural damage due to water penetration.

[0016] The present application also discloses a method for installing the lower opening structure of the waterscape curtain wall, which is characterized by comprising the following steps: a. Synchronously embed the waterscape main body and embedded parts; b. Connect the glass rib supporting steel U-channel and the large glass supporting steel U-channel to the embedded parts through supporting angle code 1 and supporting angle code 2; c. Install the glass ribs and large glass in the corresponding supporting steel U-grooves, and install flexible rubber pads at the bottom and inner and outer edges of the glass in contact with the steel U-grooves; d. Use waterproof mortar to fill the lower opening of the large glass support steel U groove; e. Apply a waterproof layer on the outdoor side to form a water-proof surface; f. The main structure of the synchronous waterscape is pre-buried with a Z-shaped water stop plate to prevent water in the waterscape from entering the lower opening of the curtain wall.

[0017] Through the above orderly construction steps, the water seepage prevention performance and structural stability of the lower opening of the waterscape curtain wall are ensured. By synchronously embedding and connecting various components, the close fit between the parts and the stability of the overall structure can be ensured. The use of flexible rubber pads provides additional shockproof and sealing effects, preventing hard contact between the glass and the metal groove and water penetration. The application of caulking waterproof mortar and waterproof layer further enhances the waterproof performance of the structure. This installation method ensures the accuracy and reliability of construction in a step-by-step manner. Each step is designed for a specific function and purpose, such as the synchronous embedding of embedded parts ensures the stability of the structure, while the setting of flexible rubber pads provides sealing and shockproof effects. In addition, the embedding of Z-shaped water stoppers prevents water penetration and ensures the long-term anti-seepage performance of the structure. In this way, the waterscape can be effectively prevented from seeping into the interior, while improving the stability and durability of the structure. The orderliness of the construction process also helps to improve construction efficiency and reduce errors and rework during construction.

[0018] Therefore, the present invention has the following beneficial effects: The simultaneous embedding of embedded parts and the connection of angle brackets enhance the stability of the structure and improve the wind pressure resistance of the curtain wall system.

[0019] The use of flexible rubber pads reduces the hard contact between the glass and the metal groove, improves shockproof performance, and reduces the risk of glass breakage.

[0020] The application of caulking waterproof mortar and outdoor waterproof layer provides double protection and effectively prevents moisture penetration.

[0021] The design of the Z-shaped water stop prevents water from the waterscape from entering the bottom of the curtain wall, reducing water erosion on the curtain wall structure and improving structural durability.

[0022] A variety of anti-seepage measures are integrated to improve the waterproof performance of the entire waterscape curtain wall, ensuring its service life and safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1 like Figure 1 As shown, a waterscape curtain wall bottom structure, the overall structure is composed of multiple modules, including glass ribs 1, large glass 2, supporting steel U-grooves, embedded parts, supporting angle codes, Z-shaped water stop plates, seam-sealing waterproof mortar and waterproof layers, their synergistic effect provides a solution with a stable structure and strong waterproof performance.

[0027] The main body of the waterscape is embedded synchronously with the embedded parts, which ensures its stability and reliability and provides a solid foundation for the entire structure. The embedded parts are usually made of reinforced concrete, and their size and depth are determined according to the force calculation to ensure sufficient grip and stability.

[0028] The lower ends of the glass ribs and large glass are fixed by glass rib supporting steel U-channels 3 and large glass supporting steel U-channels 5. These steel U-channels are made of high-strength steel and are U-shaped to provide sufficient support and stability. The size of the steel U-channel is accurately calculated according to the size and weight of the glass to ensure its load-bearing capacity.

[0029] The Z-shaped waterstop plate embedded in the main body of the waterscape is designed in a Z-shape to provide a stronger water-stopping effect, and is made of corrosion-resistant stainless steel material to adapt to possible humid environments and extend its service life.

[0030] The flexible rubber pads installed at the contact points between the bottom and inner and outer edges of the glass and the steel U-groove can reduce hard contact and prevent the glass from breaking due to hard impact. At the same time, they provide a certain buffering effect and reduce the impact of vibration on the glass.

[0031] The waterproof mortar is used to fill the lower opening of the large glass support steel U-groove to achieve a dense effect, and the waterproof layer is applied to the outdoor side after the mortar is completely dry to form a complete waterproof surface. These measures work together to provide an additional waterproof barrier.

[0032] As the anchor point of the entire structure, the embedded parts work in a similar way to the foundation of a building. They are firmly embedded in the foundation to provide support for the entire curtain wall structure. The connection between the supporting angle bracket, the steel U-channel and the embedded parts is not only firm but also allows for slight adjustments to accommodate minor errors in construction.

[0033] The working principle of the Z-type water stop is based on its shape design. The curved part of the Z shape can effectively block the flow of water and prevent water from penetrating from the main body of the waterscape into the interior of the curtain wall structure. The flexible rubber pad absorbs shock and vibration through its elasticity, protecting the glass from damage caused by hard contact.

[0034] The waterproof mechanism of the caulking waterproof mortar and waterproof layer lies in the dense structure formed after hardening, which can effectively prevent the penetration of water, and the waterproof layer further enhances this effect.

[0035] The design of the entire structure fully considers structural stability, waterproof performance, durability and construction convenience. The stability of the entire structure has been greatly improved by the synchronous embedding of embedded parts and the firm connection of angle codes. The combination of Z-type waterstop plates and waterproof mortar for plugging seams provides double waterproof protection and effectively prevents water penetration. The use of corrosion-resistant stainless steel materials and precisely proportioned mortar improves the durability of the entire structure. The design of supporting angle codes and flexible rubber pads simplifies the construction process and improves construction efficiency. In addition, other waterstop materials such as rubber waterstops or expansion waterstops can also be considered, which may provide better waterstopping effects in some cases. In addition, the use of spraying or rolling technology instead of brushing the waterproof layer can further improve the construction efficiency and the uniformity of the waterproof layer.

[0036] When the entire construction system is assembled, the connection between the waterscape body and the embedded parts 10 forms a solid foundation. The embedded parts are deeply embedded in the structure. As the support point of the entire structure, its stability is the key to whether the entire system can effectively prevent water penetration. The synchronous embedding of the embedded parts and the waterscape body ensures a close connection between the two, thus forming a reliable connection foundation.

[0037] On this basis, the installation positions of the glass ribs 1 and the large glass 2 are precisely determined. The lower ends of the glass ribs and the large glass are placed in the glass rib supporting steel U-groove 3 and the large glass supporting steel U-groove 5, respectively. This design not only provides the necessary support, but also allows the glass to be installed in a safe and stable manner. The use of the supporting angle code 1 4 and the supporting angle code 2 6 fixes the U-groove to the embedded parts, thereby ensuring the stability and bearing capacity of the entire glass structure. During the assembly process, special attention was paid to the setting of flexible rubber pads. These rubber pads, as the key part of the contact between the glass ribs and the large glass and the steel U-groove, provide the necessary buffer to prevent damage to the glass caused by hard contact. Their setting not only increases the safety of the system, but also improves the durability of the structure. Next is the installation of the Z-type water stop 7. The embedded position of the water stop is carefully designed to ensure that it can block the water in the waterscape from entering the lower end of the glass curtain wall. Its installation is not only a separate link, but also a key part of the waterproof performance of the entire system. The filling of the seam waterproof mortar 8 is another key step in the entire construction system. This mortar is filled at the bottom of the U-shaped groove to ensure that there are no gaps, thereby preventing water from penetrating. The drying process of the mortar needs to be strictly controlled to ensure that it achieves the best waterproof effect. The application of the waterproof layer 9 is the last step in the construction system. After the mortar is completely dry, the waterproof layer is applied to the outdoor side to form a complete waterproof surface. This step not only improves the waterproof effect, but also enhances the aesthetics of the entire structure.

[0038] The entire construction system works together through a series of carefully designed steps and components to form a waterproof barrier. The close combination of embedded parts and the main body of the waterscape provides a stable support foundation for the entire system. The stable connection of the steel U-channel and the supporting angle ensures the stability and load-bearing capacity of the glass structure. The setting of flexible rubber pads provides the necessary buffer and protects the glass from damage caused by hard contact. The embedded position of the Z-shaped water stop ensures that water will not be introduced into the lower opening of the glass curtain wall. The combined use of the waterproof mortar and the waterproof layer forms an airtight waterproof layer, which effectively prevents the penetration of moisture.

[0039] In this embodiment, the design and application of the Z-shaped water stop plate 7 embedded in the main body of the waterscape is the core of the entire waterproof system. The outer surface of the Z-shaped water stop plate is provided with a corrosion-resistant layer, which can be a metal coating or a special coating, and its purpose is to protect the water stop plate from corrosion in a humid environment. In addition, a magnetic adsorption layer 11 is also provided on one side of the Z-shaped water stop plate. This design ensures that the water stop plate can be more firmly attached to the main structure of the waterscape to prevent it from moving due to external forces.

[0040] In particular, the surface of the corrosion-resistant layer of the Z-type water stop plate in this embodiment is a microporous structure, and this design helps to improve the hydrophobic performance of the water stop plate. The microporous structure reduces the contact area between water molecules and the surface of the water stop plate, reduces the possibility of water adhesion, and reduces the accumulation of dirt and biofilm, maintaining the long-term performance of the water stop plate; in particular, when the temperature of the waterscape curtain wall arranged outdoors is increased due to the influence of sunlight, the microporous structure can ensure that the water vapor generated by evaporation leaves the gap between the Z-type water stop plate and the corrosion-resistant layer, avoiding the long-term accumulation of water vapor and accelerating the rust of the Z-type water stop plate.

[0041] In addition, the magnetic adsorption layer 11 can be disassembled and cleaned. This magnetic material, such as neodymium iron boron magnet, has a strong adsorption force and can adsorb metal particles mixed in the water body. It continuously enriches the metal particles during the water circulation work of the waterscape curtain wall and reduces the metal particle content in the water body, thereby reducing the erosion of the metal particles on the contact part of the lower opening of the curtain wall with the water body.

[0042] Before starting to build the curtain wall, it is first necessary to install the waterscape body and the embedded parts 10 simultaneously. The embedded parts 10 are made of high-strength materials, and their embedded depth and size are determined based on the calculation of the structural bearing capacity and stability. The embedded work of the embedded parts is usually carried out synchronously with the construction of the main structure, ensuring that the embedded parts and the main structure are tightly and firmly combined. The large glass supporting steel U-groove 5 is connected to the embedded parts 10 through the supporting angle code 2 6. The design of the supporting angle code 2 6 allows the connection between the U-groove and the embedded parts to be more secure, and the upper and lower ends of the supporting angle code are respectively connected to the U-groove and the embedded parts by welding. This connection method not only improves the stability of the structure, but also facilitates construction operations. The glass rib supporting steel U-groove 3 is connected to the embedded parts 10 through the supporting angle code 1 4. The supporting angle code 1 4 is also connected by welding to ensure the stability of the entire structure. The design of the supporting angle code 1 4 takes into account the size and weight of the glass rib 1 to ensure that it can provide sufficient support.

[0043] After the installation of the supporting structure is completed, the large glass 2 and glass rib 1 are installed. The lower ends of these two components are installed in the large glass supporting steel U groove 5 and the glass rib supporting steel U groove 3 respectively. During the installation process, special attention should be paid to setting flexible rubber pads at the lower end of the glass and the contact parts between the inner and outer ends and the steel U groove to reduce hard contact and prevent the glass from breaking due to hard impact, while playing a role of buffering and shock absorption. After the glass rib and large glass are installed, the next step of waterproofing is carried out. First, the lower end of the large glass supporting steel U groove 5 is filled with seam-filling waterproof mortar 8. This step is crucial because the filling must be dense to ensure that moisture cannot penetrate through the gap. The proportion and curing time of the mortar need to be strictly implemented according to the manufacturer's recommendations to ensure its waterproof performance. After the mortar is completely dry, the waterproof layer 9 is applied to the outdoor side to form a complete waterproof surface. The waterproof layer is applied from the side of the structural edge beam to the upper side of the large glass supporting steel U groove to ensure the waterproof performance of the entire structure.

[0044] The Z-shaped stainless steel water-stop steel plate 7 is also pre-buried synchronously with the main structure of the waterscape to prevent water in the waterscape from entering the lower opening of the glass curtain wall. The design of the Z-shaped water-stop steel plate effectively prevents water from penetrating from the waterscape area, and its pre-buried position and depth need to be determined according to the specific conditions of the waterscape design and the main structure.

[0045] This embodiment first considers the installation of embedded parts 10, which is the first step in constructing the lower opening structure of the curtain wall near the water. These embedded parts need to be installed synchronously with the main structure to ensure that they can withstand various loads that may occur in the future. The specifications and shapes of the embedded parts are determined according to mechanical calculations. Steel materials such as Q235 are usually used, and its yield strength is 235MPa, which is sufficient to cope with conventional loads. The depth and position of the embedded parts should be determined by the calculation of the structural engineer according to the stability and bearing capacity of the main structure to ensure its close fit with the main structure. Next is the installation of the supporting angle code 1 4 and the supporting angle code 2 6. These two parts are connected to the embedded parts 10 by welding to ensure the stability of the structure. During the welding process, the welding current must be strictly controlled to avoid overheating and causing the material performance to deteriorate. According to the thickness of the material and the requirements of the welding technology, the welding current is generally controlled between 60 and 120 amperes. After the welding is completed, non-destructive testing must be performed to ensure that there are no cracks or holes in the weld. Next is the installation of the glass rib 1 and the large glass 2. When installing these components, they need to be placed precisely in the corresponding U-grooves to ensure the integrity and aesthetics of the structure. In order to protect the glass from damage caused by hard contact, flexible rubber pads are installed at the bottom of the glass and the part in contact with the steel U-groove. The elasticity and durability of these rubber pads must meet specific performance requirements, such as the Shore hardness is usually controlled between 60 and 80. The subsequent filling of the gap waterproof mortar 8 is crucial to improving the waterproof performance of the structure. The filling of the mortar must ensure that there are no gaps, and the thickness is usually controlled between 20 and 30 mm. The mortar ratio should be mixed according to the ratio of cement: sand: waterproof agent = 1:2:0.05 to ensure good impermeability. The curing time of the mortar must be carried out according to the manufacturer's recommendations, usually at least 14 days, to ensure that it reaches the designed strength. Applying a waterproof layer 9 on the outdoor side is the last step of the waterproofing treatment. This coating must not only be uniform, but also ensure that there is no missing coating. The thickness of the coating should be controlled between 1.5 and 2 mm to meet the requirements of the "Code for Acceptance of Building Waterproof Engineering Quality" GB50208-2011. Finally, the pre-embedding of the Z-shaped stainless steel water-stop steel plate 7 is a key step to prevent water from penetrating from the waterscape into the interior. The water-stop steel plate should be made of 1.5mm thick 316L stainless steel material with good corrosion resistance. When pre-embedding, the position and depth of the steel plate should be closely combined with the main structure of the waterscape, ensuring that its upper edge is flush with the bottom of the waterscape.

[0046] Quality control is crucial throughout the construction process. Each step must be followed by a corresponding quality inspection, including the position and depth of embedded parts, welding quality, density of mortar filling, uniformity of coating, etc.

[0047] Example 2 This embodiment focuses on optimizing the structure of the lower opening of the water curtain wall, especially introducing a conductive metal coating as a corrosion-resistant layer, which is connected to the curtain wall grounding system. This adjustment can improve the stability and safety of the structure while ensuring its good waterproof performance.

[0048] The entire structure is built on the main body of the waterscape, including glass ribs 1 and large glass 2, which are supported by glass rib supporting steel U-grooves 3 and large glass supporting steel U-grooves 5 respectively. These U-grooves are designed to provide stable support for the glass and ensure the vertical and horizontal stability of the structure. The bottom of the U-groove is specially designed with a Z-shaped water stop plate 7, which is a key component to prevent water from entering the lower opening of the curtain wall.

[0049] In order to enhance stability and prevent any potential vibration, the supporting angle bracket 2 6 connects the large glass supporting steel U groove 5 to the embedded part 10. The embedded part 10 is embedded synchronously with the main body of the waterscape to ensure the integration and stability of the structure. At the same time, the supporting angle bracket 1 4 connects the glass rib supporting steel U groove 3 to the embedded part 10, providing a solid connection point. During the installation process of the glass rib 1 and the large glass 2, the present embodiment adds a flexible rubber pad in the U groove to ensure the buffer between the glass and the metal groove and reduce the damage caused by hard impact. In addition, the flexible rubber pad also provides an additional sealing effect to help prevent moisture penetration. At the lower mouth of the large glass supporting steel U groove 5, the present embodiment is filled with a sealing waterproof mortar 8, which not only provides structural support but also enhances the waterproof performance. After the mortar is completely dry, the present embodiment is painted with a waterproof layer 9 on the outdoor side to form an effective water-proof surface, further enhancing the waterproof effect. In order to ensure that the water in the waterscape does not enter the lower mouth of the curtain wall, the present embodiment embeds a Z-shaped water stop plate 7 when the main structure of the waterscape is embedded synchronously. The design of this water stop plate is simple and efficient, and prevents water penetration through physical isolation. The structural design of the entire embodiment 2 takes into account the three key factors of safety, stability and waterproofness. By introducing the connection of the conductive metal coating and the grounding system, this embodiment not only improves the weather resistance of the structure, but also enhances its safety. This design has shown considerable superiority in both theory and practice, providing a more reliable waterproof solution for buildings.

[0050] In this embodiment, the key point of the lower structure of the water curtain wall is the conductive metal coating of the Z-shaped water stop plate 7 and its connection with the grounding system, so as to achieve cathodic protection of the entire structure. First of all, starting from the material selection of the Z-shaped water stop plate 7, common corrosion-resistant metals such as nickel, zinc or chromium are used as coating materials. According to the electrochemical protection theory, cathodic protection is to slow down or stop the corrosion process by applying an external current or potential to make the metal a cathode.

[0051] The mathematical model of cathodic protection can be described by Faraday's law, that is, the electron loss rate of the corroded metal is proportional to the current density, and the formula is expressed as: Corrosion rate = k·icorr Where k is the proportionality constant and icorr is the corrosion current density. Cathodic protection slows down metal corrosion by reducing or eliminating corrosion current.

[0052] In cathodic protection, the conductive metal coating of the Z-type water stop plate 7 is connected to the grounding system of the curtain wall to form a galvanic pair. The metal coating acts as the cathode and the other parts of the curtain wall act as the anode, which are preferentially corroded in the electrochemical reaction. This configuration can significantly reduce the corrosion rate of the Z-type water stop plate 7.

[0053] The coating thickness on the outer surface of the Z-type water stop plate 7 is very important. The minimum thickness recommended is usually 10 microns to ensure that the coating can effectively protect the substrate and prevent the penetration of corrosive media. The coating thickness needs to be calculated based on the expected service life and environmental conditions. The coating thickness d can be estimated by the following formula: d=ρk·t Where k is the corrosion rate constant, t is the expected service life, and ρ is the density of the coating material.

[0054] The supporting structure of the glass rib 1 and the large glass 2, the glass rib supporting steel U groove 3 and the large glass supporting steel U groove 5 are designed with built-in flexible rubber pads to reduce the damage to the glass caused by hard impact. The elastic modulus of the flexible rubber pad is about 1-3MPa, which can effectively absorb impact energy.

[0055] The lower end of the U-groove 5 of the large glass support steel is filled with waterproof mortar 8, and its mix ratio is usually cement: sand = 1:2 to 1:3. The impermeability of the mortar can be determined by an impermeability test, and the impermeability grade of the mortar is usually required to be not less than P6. As the water pressure increases, the anti-penetration ability of the waterproof layer 9 needs to be verified by a water pressure penetration test. When the waterproof layer 9 is applied, the thickness must be uniform and not less than 1.5 mm to ensure sufficient waterproof effect.

[0056] The embedded parts 10 are embedded synchronously with the main body of the waterscape, and connected to the large glass support steel U-groove 5 through the support angle code 2 6, and connected to the glass rib support steel U-groove 3 through the support angle code 1 4, ensuring the stability of the overall structure. The anchoring depth of the embedded parts is at least 50 mm to ensure its bonding strength with the concrete.

[0057] Through the above design, the conductive metal coating of the Z-shaped water stop plate 7 achieves cathodic protection, significantly improving corrosion resistance. In addition, the stability and waterproof performance of the structural structure have also been carefully designed and constructed to meet the use requirements of the water curtain wall. The reliability and effectiveness of the design are ensured through the combined analysis of theoretical models and actual structures.

[0058] The dynamic analysis of the lower opening structure of the curtain wall near the water needs to start with the installation of embedded parts, and describe in detail the construction, connection and use process of the entire structure. As the foundation of the entire structure, the embedded parts must first be firmly connected to the main structure of the building and fixed by chemical anchors or welding to ensure that their pull-out strength is not less than 50kN. Before pouring concrete, the embedded parts need to be protected with plastic sleeves or protective boxes to prevent damage during construction.

[0059] In this embodiment, the installation of the glass ribs and the large glass is carried out immediately after the embedded parts are cured. The glass rib supporting steel U-groove and the large glass supporting steel U-groove are connected to the embedded parts through the supporting angle code, and bolt connection is a common method. At this stage, care should be taken to ensure that the connection between the supporting angle code and the U-groove is stable to support the weight of the glass. Subsequently, a flexible rubber pad is installed in the U-groove, and its elastic modulus is about 1-3MPa to absorb possible impact energy and provide buffering. The sealing waterproof mortar is filled into the lower mouth of the large glass supporting steel U-groove to enhance the sealing of the structure. The proportion and filling process of the mortar must be strictly implemented in accordance with the construction specifications to ensure its uniformity and density. The outdoor side is painted with a waterproof layer with a thickness of not less than 1.5 mm to improve the waterproof ability. The installation of the Z-type water stop plate is a key step. It needs to be embedded synchronously with the U-groove and connected to the grounding system of the curtain wall through a conductive metal coating to achieve cathodic protection. After the structure is completed, the cathodic protection system needs to be debugged, and a professional potential measuring instrument is used to ensure that the potential error is controlled within ±0.1 volt. After the structure is put into use, regular inspection and maintenance are necessary.

[0060] In actual application, problems such as corrosion, temperature deformation, structural leakage and load-bearing capacity may be encountered. To solve these problems, you can consider using more corrosion-resistant materials such as stainless steel or copper alloy, setting temperature expansion joints to adapt to the displacement caused by temperature changes, adding polymer waterproof membranes to improve waterproof performance, and increasing the number of embedded parts or using larger supporting angles to improve the load-bearing capacity of the structure.
