Description
Technical Field
[0001] The utility model relates to the technical field of glass curtain wall design, in particular to a curtain wall bottom opening structure near water. Background Art
[0002] In real estate development, waterscape design is a key element in enhancing project quality, and its importance is self-evident. In modern architecture, incorporating water features beneath floor-to-ceiling glass curtain walls, particularly due to their unique visual appeal and ecological value, has become a sought-after design concept among many real estate developers. However, when implementing curtain wall underpass waterscapes, many construction companies still rely on traditional methods: filling the underpass of aluminum alloy curtain wall beams with rock wool for waterproofing. This traditional construction technique has significant practical drawbacks, particularly regarding the waterproofing and sealing performance of the curtain wall underpass, resulting in unsatisfactory results.
[0003] Due to the limited waterproof properties of rock wool and the potential for poor sealing during construction, the curtain wall undercut area is a vulnerable spot for water seepage. When rainwater or groundwater seeps into the interior through the gaps in the curtain wall undercut, it not only causes moisture to build up on the floor but can also create noticeable water stains. Prolonged exposure to moisture can cause irreversible damage to indoor paving materials, such as wood floors, such as deformation and mildew, severely impacting the building's service life and occupant comfort. Faced with these issues, developers and construction companies are forced to frequently perform repairs and treatments, which not only incurs additional financial costs but can also delay project schedules.

DETAILED DESCRIPTION
[0019] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.
[0020] A curtain wall bottom opening structure at the waterside of this embodiment, such as Figure 1As shown, the utility model includes a large glass 2 and a glass rib. The lower end of the large glass 2 is installed in the large glass supporting steel U-groove 5 by bolts, and the lower end of the glass rib 1 is installed in the glass rib supporting steel U-groove 3 by bolts. The large glass is located on the outdoor side, and the glass rib 1 is located on the indoor side. The large glass supporting steel U-groove 5 and the glass rib supporting steel U-groove 3 are arranged side by side. The top of the large glass supporting steel U-groove 5 and the top of the glass rib supporting steel U-groove 3 are located in the same horizontal plane, and the bottom of the large glass supporting steel U-groove 5 and the bottom of the glass rib supporting steel U-groove 3 are located in the same horizontal plane. This design not only ensures the symmetry of the structure, but also facilitates construction and maintenance.
[0021] like Figure 3 As shown: The embedded part 10 is a key component connecting the curtain wall and the main structure. It is located below the large glass supporting steel U-channel 5 and the glass rib supporting steel U-channel 3. The embedded work is carried out simultaneously with the construction of the main structure, ensuring the firm connection between the curtain wall and the main body of the building, and providing a solid foundation for the stability and durability of the entire building. The large glass supporting steel U-channel 5 is connected to the embedded part 10 through the supporting angle a6. The supporting angle a6 is L-shaped. The vertical surface of the supporting angle a6 is tightly connected to the vertical surface of the large glass supporting steel U-channel 5 by welding, and the horizontal surface is welded to the embedded part 10 to form a stable support structure. The top of the supporting angle a6 is on the same horizontal plane as the top of the large glass supporting steel U-channel 5. There are two supporting angles a6, respectively set on the indoor and outdoor sides of the large glass supporting steel U-channel 5 to evenly distribute the force and enhance the stability of the structure. The glass rib supporting steel U-channel 3 is connected to the embedded component 10 via the supporting angle bracket b4. The upper limb of the supporting angle bracket b4 is welded to the glass rib supporting steel U-channel 3, while the lower limb is welded to the embedded component 10, ensuring stable support for the glass rib 1. This connection method not only provides the necessary structural strength but also facilitates subsequent maintenance and adjustment.
[0022] The large glass panel 2 and the lower ends of the glass ribs 1 are installed within the steel U-channels 5 and 3 supporting the large glass panel and glass ribs, respectively. To further enhance the stability of the connection between the glass and the supporting structure and prevent glass shattering due to hard contact, the design incorporates flexible rubber pads 12 where the lower end and inner and outer ends of the glass meet the steel U-channels. These rubber pads not only provide the necessary cushioning but also, through their elastic properties, effectively absorb and disperse stresses generated by temperature fluctuations, wind pressure, or minor structural displacements, preventing localized stress concentrations that could lead to glass breakage.
[0023] like Figure 2As shown, a waterproof mortar layer 8 is provided beneath the large glass support steel U-groove 5. The lower opening of the large glass support steel U-groove 5 is caulked tightly to ensure both watertightness and airtightness. The mortar layer 8 extends not only beneath the large glass support steel U-groove 5 but also beneath the adjacent glass rib support steel U-groove 3, forming a continuous waterproof barrier. The mortar layer is located above the embedded component 10. The lower horizontal surface of the support angle bracket b4 is entirely within the mortar layer 8. The horizontal surface and part of the vertical surface of the support angle bracket a6 are also within the mortar layer 8.
[0024] A waterproof layer 9 is applied to the outside of the caulking mortar layer to strengthen the anti-leakage structure of this part. The waterproof layer 9 covers the area from the bottom of the caulking waterproof mortar to the top of the large glass support steel U-channel 5. This ensures that the waterproof layer 9 can cover all possible seepage paths, forming a continuous and complete waterproof barrier.
[0025] The waterproof layer 9 is arranged on the outdoor side of the Z-shaped waterstop plate 7, and provides additional waterproof protection for the curtain wall through its special geometric shape. The top of the Z-shaped waterstop plate 7 and the top of the large glass supporting steel U-channel 5 are on the same horizontal plane, and the bottom end is inserted into the outdoor concrete structure to achieve a firm connection with the main structure of the building and waterproof protection for the curtain wall. The horizontal surface of the Z-shaped waterstop plate 7 is in contact with the outdoor concrete structure and is located above the outdoor concrete structure, which enhances the stability of the waterstop plate and improves the waterproof effect through close integration with the concrete structure. The two 90-degree turning points of the Z-shaped waterstop plate 7 are both located on the plane of the outdoor concrete structure. The vertical surface of the Z-shaped waterstop plate 7 located above the outdoor concrete structure passes through the water surface, forming waterproof protection for the curtain wall. The vertical surface of the outdoor side supporting angle bracket a6 is in contact with the vertical surface of the Z-shaped waterstop plate 7 to form a back-to-back support structure. This structure not only enhances the supporting force of the waterstop plate, but also improves the stability of the waterstop plate through the fixation of the angle bracket. The top of the supporting angle bracket a6 and the top of the Z-shaped water stop plate 7 are on the same horizontal plane, and the turning point of the supporting angle bracket a6 is located a distance above the turning point of the Z-shaped water stop plate 7. A layer of waterproof glue 14 is applied to the outdoor side of the Z-shaped water stop plate 7 located above the outdoor concrete structure. The waterproof glue 14 layer is L-shaped on the Z-shaped water stop plate 7. A section of waterproof glue 14 is also provided on the upper end of the indoor side of the portion of the large glass supporting steel U-channel 5 close to the Z-shaped water stop plate 7. This design not only improves the waterproof performance of the water stop plate, but also installs a protective cover 13 on the waterproof glue 14 through the bonding effect of the waterproof glue 14. The protective cover 13 is composed of two L-shaped parts, which respectively cover the outdoor side of the Z-shaped water stop plate 7 located above the outdoor concrete structure, a distance above the upper end of the indoor side of the portion of the large glass supporting steel U-channel 5 close to the Z-shaped water stop plate 7, the top of the large glass supporting steel U-channel 5, the top of the outdoor supporting angle bracket a6, and the top of the vertical surface of the Z-shaped water stop plate 7 located at the upper end of the outdoor concrete structure. The protective cover 13 not only forms support and protection for the large glass supporting steel U-groove 5, the outdoor side supporting angle code a6 and the Z-shaped water stop plate 7, but also forms a cavity with the top of the large glass supporting steel U-groove 5, the outdoor side supporting angle code a6 and the top of the Z-shaped water stop plate 7. This cavity design not only improves the waterproof performance of the entire system, but also reduces the direct contact of moisture with the structure through the formation of the cavity, thereby improving the durability of the curtain wall. The material of the Z-shaped water stop plate 7 is stainless steel, which not only has good corrosion resistance and weather resistance, but also has excellent strength and rigidity, and can withstand stress and deformation under various environmental conditions. The selection of this material ensures the long-term stability and durability of the water stop plate, providing a reliable waterproof guarantee for the curtain wall system.
[0026] The invention discloses a construction process of a curtain wall lower opening structure near water.
[0027] (1): The embedded parts 10 are embedded synchronously with the main structure. The main structure is set next to the water surface 15. The precise positioning and fixation of the embedded parts 10 are the basis for the subsequent curtain wall installation work. After the embedded parts 10 are installed and confirmed to be correct through quality inspection, the main structure of the glass curtain wall is installed next. After the embedded parts 10 are installed, the large glass supporting steel U-channel 5 is connected to the embedded parts 10 through the supporting angle code a6. The supporting angle code serves as a connecting part to firmly fix the steel U-channel on the embedded parts 10. The two L-shaped supporting angle codes a6 are arranged side by side in parallel. The vertical surfaces of the two supporting angle codes a6 need to be precisely aligned with the outdoor and indoor sides of the large glass supporting steel U-channel 5, and a firm connection is achieved through a welding process. At the same time, the horizontal surfaces of the lower ends of the two supporting angle codes a6 are welded to the horizontal surface of the embedded parts 10 to ensure the stability of the overall structure. When installing the glass rib supporting steel U-channel 3, the supporting angle code b4 is used to achieve the connection. The upper limb of the support angle bracket b4 is welded to the glass rib support steel U-channel 3, while the lower limb is welded to the embedded component 10. This installation method ensures the stability and load-bearing capacity of the glass rib 1. The welding process must strictly follow welding specifications to ensure that the weld quality meets the requirements of structural strength and durability. To achieve good waterproof performance, a certain gap is required between the large glass support steel U-channel 5 and the glass rib support steel U-channel 3 and the embedded component 10. This gap will be filled with waterproof mortar.
[0028] (2) The lower end of the large glass panel 2 is tightly connected to the upper structure of the large glass supporting steel U-channel 5 via dedicated bolts to achieve vertical force transmission. Similarly, the glass rib supporting steel U-channel 3 is also connected to the lower end of the glass rib 1 using bolts to ensure that the glass rib 1 can effectively support the weight of the glass curtain wall. Flexible rubber pads 12 are installed at the contact points between the lower end and the inner and outer ends of the glass and the steel U-channel for transition. The flexible rubber pads 12 have excellent elasticity and resistance to compression deformation, and can provide the necessary buffering and sealing transition between glass and metal to prevent the glass from shattering due to hard contact. During the construction process, the selection and installation of the flexible rubber pads 12 must comply with strict engineering specifications and design requirements. The material selection, thickness, hardness, and coordination of the rubber pads with the glass and steel U-channel all require precise calculation and testing to ensure that they can achieve the best results in actual use. Through this carefully designed and constructed connection method, not only can the safety and durability of the curtain wall system be improved, but the overall aesthetics and functionality of the building can also be enhanced.
[0029] (3): After the glass is installed, use waterproof mortar to caulk the lower end of the large glass supporting steel U-groove 5. The caulk needs to be dense to form a waterproof mortar layer 8 to ensure the density and waterproofness of the caulk. The waterproof mortar layer 8 is distributed below the large glass supporting steel U-groove 5 and the glass rib supporting steel U-groove 3, and is located above the embedded parts 10. This layout is intended to provide a solid waterproof foundation for the curtain wall system. During the construction process, the density of the waterproof mortar is the key. By adopting professional construction techniques and tools, it is ensured that the mortar layer reaches the required density during the filling process, thereby forming an effective waterproof barrier. In addition, the thickness and uniformity of the mortar layer are also the focus of construction quality control to ensure the consistency and reliability of the waterproof effect.
[0030] (IV): After the mortar is completely dry, apply the waterproof layer 9 evenly on the outdoor side of the caulking waterproof mortar layer 8 to strengthen the anti-leakage structure of this part. The waterproof layer 9 needs to be applied from the bottom end of the caulking waterproof mortar layer 8 to the outdoor top end of the large glass supporting steel U groove 5 to ensure the formation of a seamless and complete waterproof layer. During the construction process, the application of the waterproof layer 9 needs to be carried out in strict accordance with the construction specifications. First, the outdoor surface of the caulking mortar layer needs to be thoroughly cleaned and treated to ensure that the waterproof layer 9 can form a good bond with the base layer. Then, use a professional waterproof coating and apply it evenly over the entire coverage area according to the specified thickness and process requirements. After the construction of the waterproof layer 9 is completed, strict quality inspection and testing are required to ensure the integrity and functionality of the waterproof layer 9. This includes testing the thickness, uniformity and bonding strength of the waterproof layer 9, as well as conducting simulated rainwater penetration tests to verify the actual anti-seepage effect of the waterproof layer 9.
[0031] (V): The Z-shaped water stop plate 7 is pre-buried synchronously with the main structure of the waterscape. The vertical surface of the bottom end of the Z-shaped water stop plate 7 is inserted into the outdoor concrete structure, and the horizontal surface is in contact with the outdoor concrete structure. It is arranged above the outdoor concrete structure, and the vertical surface of the upper end is in contact with the vertical surface of the outdoor support angle code a6, forming a back-to-back support structure. The top of the Z-shaped water stop plate 7 and the top of the large glass supporting steel U-groove 5 are installed on the same horizontal plane. A layer of waterproof glue 14 is applied to the outdoor side of the vertical and horizontal surfaces of the Z-shaped water stop plate 7 above the outdoor concrete structure, and a section of waterproof glue 14 is applied to the upper end of the indoor side of the large glass supporting steel U-groove 5 near the Z-shaped water stop plate 7. This waterproof glue 14 usually has good adhesion and weather resistance to ensure long-term waterproof effect. Place the protective cover 13 corresponding to the distribution position and shape of the waterproof glue 14 on the waterproof glue 14. The installation of the protective cover 13 must ensure that it is tightly fitted with the large glass supporting steel U-groove 5, the vertical surface of the outdoor side supporting angle code a6 and the Z-shaped water stop plate 7 to form a complete protection system, thereby ensuring the waterproof performance and durability of the entire structure.
[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
