[0039] like Figure 1 As shown, an embodiment of the present invention provides a high-performance waterproof drainage structure for stone curtain walls, including a stone panel assembly, a waterproof sealing assembly, and a connection and fixing assembly. The stone panel assembly includes a stone plate 1 provided with a T-slot, a limit hole 7, and a first threaded hole, the waterproof sealing assembly includes a T-block 2 and a concave rubber block 3 for sealing the transverse gap, and a concave-convex rubber pad 16 for sealing the longitudinal gap, and the concave-convex groove of the concave-convex rubber pad 16 is used as a longitudinal drainage channel, and the groove of the concave rubber block 3 is used as a transverse drainage channel to form a waterproof and drainage system for the stone curtain wall, and the connection and fixing assembly fixes the various components by screw nails to stably fix the stone plate on the column and the beam, separate the stone plate from the civil wall, realize the dual functions of waterproofing and drainage, and effectively prevent the problem of water seepage in the gaps of the stone curtain wall.

[0040] Specifically, Figure 1-Figure 4 As shown, the stone panel assembly includes multiple groups of stone panels 1, which constitute the main part of the curtain wall and provide external protection and aesthetic decoration. The stone panels 1 are provided with a series of T-shaped grooves at the upper and lower ends, and limited holes 7 are provided on the left and right surface edges for installing and fixing the waterproof sealing assembly. The surface of the stone panels is also provided with multiple first threaded holes for installing and fixing the connecting and fixing assembly.

[0041] The waterproof sealing assembly includes a T-block 2, a concave rubber block 3, a limit pin 14, a support plate 15 and a concave-convex rubber pad 16. The concave rubber block 3 is fixedly connected to the side of the middle part of the T-block 2, and its groove can be used as a drainage channel. The T-block 2 is slidably installed in the T-slot of the stone board 1. When rainwater falls on the stone board, it plays a role in preventing water from penetrating into the horizontal gaps, and the concave rubber block 3 connected to the side of the T-block 2 can be used as a drainage channel to drain water from the horizontal gaps. The concave rubber block 3 can also prevent the stone board 1 from being fixed on the wall for a long time and being squeezed against each other under the action of gravity, causing the stone board 1 to deform. The end of the support plate 15 is provided with a threaded hole with the same diameter as the limiting hole 7 of the stone plate 1, and the support plate 15 is fixed to the stone plate 1 by the limiting nail 14. The surface of the support plate 15 is also fixedly connected with the concave-convex rubber pad 16, so that the concave-convex rubber pad 16 is fixed in the longitudinal gap to block water from the outside, thereby preventing water from penetrating the longitudinal gap and preventing the stone plates 1 from squeezing each other to cause deformation of the wall. The concave-convex groove of the concave-convex rubber pad 16 can be used as a longitudinal drainage channel.

[0042] The T-block 2 can be firmly slidably installed in the T-slot of the stone slab 1, which not only provides the necessary support for the stone slab, but also helps to form an effective physical barrier to prevent moisture from penetrating along the transverse gaps between the stone slabs. The concave rubber block 3 is fixedly connected to the T-block 2 and plays a dual role. On the one hand, it serves as a drainage channel to guide the water entering the transverse gap to flow out and avoid the problems caused by water accumulation; on the other hand, due to its soft and elastic characteristics, it can absorb the pressure that may be generated between the stone slabs under the action of gravity to a certain extent, reducing the risk of deformation of the stone slab. The limit nail 14 fixes the support plate 15 on the stone slab 1, and the waterproof performance of the longitudinal gap is enhanced by the concave-convex rubber pad 16 fixed on the surface of the support plate 15. The use of threaded holes to match the limit nails 14 not only facilitates the installation process, but also enhances the safety of the structure. The unique concave-convex structure on the surface of the concave-convex rubber pad 16 can not only effectively block the intrusion of external moisture, but also constitute a small longitudinal drainage system, which helps to drain any unexpected infiltration of moisture. In addition, this design helps to alleviate minor displacements or squeezing between adjacent stone slabs caused by environmental factors (such as temperature changes), thereby protecting the wall from damage.

[0043] The waterproof sealing component achieves the purpose of both waterproofing and enhancing structural stability through a clever combination of material selection, shape design and installation method.

[0044] The connection and fixing assembly includes a first threaded nail 4, an L-shaped block 5, a second threaded nail 6, a fixing block 8, a round elastic pad 9, a limit block 10, 11-elastic sheet, a third threaded nail 12 and a fixing plate 13. The first threaded hole provided on the surface of the stone board 1 is internally threaded to connect the first threaded nail 4, and a first threaded hole is also provided at one end of the L-shaped block 5; the first threaded nail 4 passes through the first threaded hole of the L-shaped block 5 and is connected to the first threaded hole of the stone board 1 to fix the L-shaped block 5 on the stone board 1. The fixing block 8 is rectangular, and the other end of the L-shaped block 5 and the surfaces of both ends of the fixing block 8 are provided with second threaded holes matching the second threaded nail 6, and the surfaces of the second threaded holes are fixedly connected with circular elastic washers 9, and the sides of both ends of the fixing block 8 are also provided with limiting grooves, and the sizes of the limiting grooves are adapted to the L-shaped block 5. The end of the L-shaped block 5 provided with the second threaded hole is inserted into the limiting groove of the fixing block 8, and after the second threaded nail 6 passes through the circular elastic washer 9 and the second threaded hole, the end nut is tightened to fix the fixing block 8 to the L-shaped block 5. The limit block 10 is an I-shaped steel structure, one end of which is fixedly connected to the middle of the fixed block 8 through a rectangular groove, and the size of the rectangular groove at the other end is adapted to the fixed plate 13. The surfaces of the two side plates of the rectangular groove are provided with third threaded holes, and the elastic sheet 11 is fixedly connected to the upper surface. The fixed plate 13 is also provided with a third threaded hole. The fixed plate 13 is inserted into the rectangular groove of the limit block 10, and the fixed plate 13 and the limit block 10 are fixed by passing the third threaded nail 12 through the third threaded hole, thereby forming a stable fixed connection component, and separating the stone plate 1 from the civil wall, and connecting the fixed plate 13 with the beams and columns and then connecting with the wall embedded parts, so as to form a ready-made stone curtain wall. The material of the limit block 10 is selected from materials with excellent corrosion resistance, which is suitable for use in strong corrosive media and high temperature difference environments.

[0045] The structure of the present invention realizes the connection of longitudinally adjacent stone panels 1 and seals the transverse gap by slidingly installing the T-block 2 fixed with the concave rubber block 3 inside the T-slot of the upper and lower stone panels; the connection of transversely adjacent stone panels is realized by passing the limiting nails 14 through the threaded holes on the support plate 15 and threading them into the limiting holes 7 on the surface of the stone panel 1, and the longitudinal gap is sealed by the concave-convex rubber pads 16, so that multiple groups of stone panels are neatly installed and the stone panels are stably fixed on the columns and beams through the connecting and fixing components, and installed on the outside of the civil wall through the adapter, so as to form a stone curtain wall and seal the gaps of the curtain wall. When rain falls on the stone curtain wall, the T-block 2 fixed with the concave rubber block 3 and the concave-convex rubber pad 16 play a waterproof role, preventing moisture from penetrating into the gaps between the stone plates. At the same time, the groove fixedly connected with the concave rubber block 3 on the side of the T-block 2 can be used as a transverse drainage channel to guide the water in the transverse gaps into the concave-convex groove of the concave-convex rubber pad 16 between the longitudinal gaps and then drain it longitudinally downward, thereby achieving the dual functions of waterproofing and drainage, effectively preventing rainwater from penetrating and eroding, protecting the structural safety of the stone curtain wall, and extending its service life.
