[0002] Currently, the installation and construction of traditional outward-tilting glass curtain walls have the following drawbacks: 1. Defects in connection structure: Traditional T-shaped keel and aluminum alloy base are fixed on site with machine screws. Due to insufficient processing precision, the connection strength is low, which poses a safety hazard. In particular, it is easy to loosen when the outward tilting curtain wall is subjected to large wind loads. 2. Inappropriate stress on the thermal insulation strip: The thermal insulation strip of the thermal insulation aluminum alloy profile needs to directly bear the mechanical load, but the tensile strength of the thermal insulation material is insufficient. It is prone to deformation or breakage after long-term use, thus affecting the safety and energy-saving performance of the curtain wall. Summary of the Invention

Detailed Implementation

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method, in conjunction with its accompanying drawings, will be used to describe the solution.

[0021] A reinforced connection structure for an outward tilting glass curtain wall includes a cross-shaped steel keel 1. A base 2 is inserted into the outer end of the cross-shaped steel keel 1 and the two are fixedly connected at the insertion point by bolts 9. The outer end of the base 2 is located between the opposite ends of two adjacent glass panels 4, and a U-shaped heat insulation strip 8 with an inward opening is provided on the outer side of the section of the base 2 between the opposite ends of two adjacent glass panels 4.

[0022] The outer end of the base 2 is connected to a glass pressure plate 6 via bolt 2 10. The glass pressure plate 6 is made of galvanized steel plate, and an aluminum alloy pressure plate 5 is provided on the outer side of the glass pressure plate 6. The two ends of the glass pressure plate 6 are parallel to the corresponding glass panel 4 to ensure that the glass pressure plate 6 can adapt to the installation requirements of the outward tilting glass curtain wall and press the glass panel 4 tightly. The shape of the aluminum alloy pressure plate 5 is adapted to the shape of the glass pressure plate 6. The outer end of the base 2 is provided with a T-shaped mounting groove 13 for installing bolt 2 10. The bolt 2 10 passes through the U-shaped thermal insulation strip 8, the glass pressure plate 6, and the aluminum alloy pressure plate 5 and is threaded with a locking nut. An aluminum alloy buckle cover 7 is snapped onto the outer side of the aluminum alloy pressure plate 5. The aluminum alloy buckle cover 7 is waterproof and can also cover the internal structure, making the overall structure aesthetically pleasing.

[0023] The base 2 is an aluminum alloy base, which is a prefabricated component in the factory. The middle part of the base 2 is a U-shaped structure 14 with an inward opening. The outer end of the cross-shaped steel keel 1 is inserted into the U-shaped structure 14 and fixedly connected by bolts 9.

[0024] The bottom of the inner cavity of the U-shaped heat insulation strip 8 is bonded to the outer end face of the base 2 with a high-strength adhesive (such as silicone structural adhesive), ensuring a firm bond between the U-shaped heat insulation strip 8 and the base 2, and that the adhesive joint is continuous and free of air bubbles. Gaps are left between the left and right sides of the U-shaped heat insulation strip 8 and the corresponding ends of the glass panel 4, allowing the U-shaped heat insulation strip 8 to serve only a sealing function, preventing deformation under pressure or tension, and ensuring stable heat insulation performance.

[0025] The U-shaped structure 14 has two symmetrically integrally formed pressure plates 12 on both sides of its open end. A receiving groove 15 for bolt 9 is formed between the two pressure plates 12 on the same side. A sealing cap 3 is snap-fitted onto the outside of the receiving groove 15. The two pressure plates 12 on the same side are respectively sealed to the glass panel 4 and the cross-shaped steel keel 1 using sealing strips. The sealing cap 3 is installed after bolt 9 is installed. The sealing cap 3 serves to waterproof the structure and also conceal bolt 9, making the overall structure aesthetically pleasing.

[0026] Drainage outlets 11 are provided on the upper half of the aluminum alloy pressure plate 5 and the lower side of the aluminum alloy buckle cover 7. In rainy or snowy weather, the water inside the structure of this utility model can be discharged in time through the drainage outlets 11.

[0027] A gasket is provided between the U-shaped heat insulation strip 8 and the glass pressure plate 6 to prevent direct heat conduction. Gaskets are also provided between the middle of the aluminum alloy pressure plate 5 and the glass pressure plate 6. Sealant is applied between the ends of the aluminum alloy pressure plate 5, the glass pressure plate 6, and the aluminum alloy cover 7. Silicone weather-resistant sealant is applied between the U-shaped structure 14 of the base 2 and the end of the glass panel 4. This structure ensures the sealing performance and stability of the overall structure.

[0028] This invention uses a cross-shaped steel keel 1 instead of the traditional T-shaped keel. The weight of the tilted glass directly transmits the tensile and shear forces on the base to the cross-shaped steel keel 1, enhancing its bending and shear resistance and making the stress distribution more reliable. The base 2 with a U-shaped structure 14 forms a rigid node with the keel through mechanical connection, improving the load-bearing capacity of the connection structure and meeting the high load requirements of the outward-tilting curtain wall.

[0029] Both bolt 9 and bolt 10 of this utility model are stainless steel bolts with a strength grade ≥A2-70. High-precision fastening is achieved through torque control to avoid on-site processing errors. The preload of bolt 9 and bolt 10 is applied according to the design specifications to ensure that there is no loosening of the contact surface.

[0030] Technical features not described in this utility model can be implemented using existing technology and will not be elaborated here. This utility model is not limited to the specific embodiments described above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
