Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of stone curtain wall drainage, more specifically, relates to a high-performance waterproof drainage structure for stone curtain wall and a construction method. BACKGROUND

[0002] Stone curtain wall is a common building exterior decoration method, which is widely used in various buildings due to its aesthetic and durable characteristics. However, in practical application, the waterproofing and drainage of stone curtain wall have always been a difficult problem plaguing the industry. The traditional waterproofing method for stone curtain wall usually uses adhesive glue to seal gaps, but this method is prone to delamination and damage under long-term sun and rain, causing water to enter the internal structure of the stone, and further causing erosion and damage to the curtain wall structure, which may eventually lead to falling and other risks, seriously affecting the durability and safety of the stone curtain wall.

[0003] In order to solve the above problems, the industry has also proposed some new stone curtain wall waterproofing and drainage technologies. For example, the patent document with application number CN202220730975.X provides a high-performance waterproof drainage structure for stone curtain wall, which includes a jointing plate connected to the side of the granite through bolts, a rubber gasket fixedly connected to the inner wall of the fixed plate, a square tube fixedly connected to the surface of the building exterior wall, and a clamping block inserted into the inner wall of the fixed plate. The lower surface of the clamping block is fixedly connected with a T-shaped support plate for fixing on the upper surface of the square tube. The high-performance waterproof drainage structure for stone curtain wall is provided with a fixed plate, a rubber gasket, a square tube, a T-shaped support plate and a jointing plate, which are set up by the construction personnel to reasonably divide the large-area granite stone curtain wall. The jointing plate is installed in a way that one end is connected with a stainless steel insert and the other end is flexible rubber pad, which is aesthetically pleasing and effectively avoids the problem of expansion and compression between the panels. The clamping block is inserted into the fixed plate and tightly connected with the rubber gasket, making the two more tightly fixed. Another example is the patent document with application number CN202223564355.2, which provides a high-performance waterproof drainage structure for stone curtain wall, which includes a stone plate. The stone plate is provided with multiple groups and is installed in an orderly manner. The four edges of the stone plate are provided with installation grooves, and installation strips are inserted and installed in the installation grooves. Rubber strips are provided on the upper and lower sides of the installation strips, and T-shaped strips are glued to the rear ends of the rubber strips. T-shaped grooves are provided on the upper and lower sides of the installation strips, and the T-shaped strips are inserted into the T-shaped grooves. The utility model can fix and install the water guide plate by setting the installation strip, and can drain water when it rains by setting multiple groups of water guide plates to avoid long-term soaking of the stone, which can cause damage. In addition, the use of rubber strips to reinforce the gap between the two groups of stone plates greatly improves the waterproofness of the device.

[0039] As Figure 1 shown, the embodiment of the present application provides a waterproof drainage structure for high-performance stone curtain wall, which comprises a stone panel assembly, a waterproof sealing assembly, and a connecting and fixing assembly. The stone panel assembly comprises a stone plate 1 provided with a T-shaped groove, a limiting hole 7 and a first threaded hole, the waterproof sealing assembly comprises a T-shaped block 2 and a concave rubber block 3 for sealing the horizontal gap, and a concave-convex rubber pad 16 for sealing the vertical gap, and the concave-convex groove of the concave-convex rubber pad 16 serves as a vertical drainage channel, and the groove of the concave rubber block 3 serves as a horizontal drainage channel, which together constitute the waterproof and drainage system of the stone curtain wall, and the connecting and fixing assembly is used to fix and connect the components by threaded nails, so as to stably fix the stone plate on the vertical column and the horizontal beam, separate the stone plate from the civil wall surface, realize the dual functions of waterproofing and drainage, and effectively prevent the water seepage problem of the stone curtain wall gap.

[0040] Specifically, as Figures 1-4 shown, the stone panel assembly comprises a plurality of stone plates 1, which constitute the main part of the curtain wall and provide external protection and aesthetic decoration. A series of T-shaped grooves are formed at the upper and lower ends of the stone plate 1, and limiting holes 7 are formed at the surface edges of the left and right sides for installing and fixing the waterproof sealing assembly, and a plurality of first threaded holes are formed on the surface of the stone plate 1 for installing and fixing the connecting and fixing assembly.

[0041] The waterproof sealing assembly includes a T-shaped block 2, a concave rubber block 3, a limiting nail 14, a support plate 15, and a concave-convex rubber pad 16. The concave rubber block 3 is fixedly connected to the side surface of the middle part of the T-shaped block 2, and the concave groove thereof can serve as a drainage channel. The T-shaped block 2 is slidingly installed in the T-shaped groove of the stone slab 1, and when rain falls on the stone slab, it prevents water from penetrating through the horizontal gap. The concave rubber block 3 connected to the side surface of the T-shaped block 2 can serve as a drainage channel to guide the water in the horizontal gap out. The concave rubber block 3 can also prevent the stone slabs 1 from being pressed against each other due to gravity when they are fixed on the wall for a long time, thereby preventing the deformation of the stone slabs 1. The support plate 15 has a threaded hole at the end thereof, which has the same diameter as the limiting hole 7 of the stone slab 1. The limiting nail 14 is used to fix the support plate 15 to the stone slab 1. The surface of the support plate 15 is also fixedly connected to the concave-convex rubber pad 16, thereby fixing the concave-convex rubber pad 16 in the longitudinal gap and blocking the water outside, which prevents water from penetrating through the longitudinal gap and prevents the stone slabs 1 from being pressed against each other, thereby preventing the deformation of the wall surface. The concave-convex groove of the concave-convex rubber pad 16 can serve as a longitudinal drainage channel.

[0042] The T-shaped block 2 is stably slidingly installed in the T-shaped groove of the stone slab 1, which not only provides necessary support for the stone slab but also helps to form an effective physical barrier to prevent water from penetrating through the horizontal gap between the stone slabs. The concave rubber block 3 fixedly connected to the T-shaped block 2 plays a dual role. On the one hand, it serves as a drainage channel to guide the water in the horizontal gap out, avoiding the problems caused by water accumulation. On the other hand, due to its soft and elastic properties, it can absorb the pressure between the stone slabs to some extent, reducing the risk of deformation of the stone slabs. The limiting nail 14 fixes the support plate 15 to the stone slab 1, and the concave-convex rubber pad 16 fixed to the surface of the support plate 16 enhances the waterproof performance of the longitudinal gap. The use of threaded holes with the limiting nail 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 not only effectively blocks external water but also forms a small longitudinal drainage system, which helps to drain any accidental water intrusion. In addition, this design helps to alleviate the slight displacement or pressure between adjacent stone slabs caused by environmental factors such as temperature changes, thereby protecting the wall surface from damage.

[0043] The waterproof sealing assembly achieves the purpose of preventing water and enhancing structural stability through the clever combination of material selection, shape design, and installation method.

[0044] The connecting and fixing assembly comprises a first threaded nail 4, an L-shaped block 5, a second threaded nail 6, a fixing block 8, a round elastic pad 9, limiting blocks 10 and 11, an elastic piece 11, a third threaded nail 12 and a fixing plate 13. The first threaded nail 4 is connected with the first threaded hole in the surface of the stone plate 1 through the internal thread, and the L-shaped block 5 has a first threaded hole in one end; the first threaded nail 4 is connected in the first threaded hole of the stone plate 1 through the first threaded hole of the L-shaped block 5 to fix the L-shaped block 5 on the stone plate 1. The fixing block 8 is rectangular, and the other end of the L-shaped block 5 and both ends of the fixing block 8 have second threaded holes matched with the second threaded nail 6, and the surface of the second threaded hole is fixedly connected with the round elastic pad 9; limiting grooves are further formed in the side surfaces of both ends of the fixing block 8, and the limiting grooves are matched with the L-shaped block 5 in size; the end of the L-shaped block 5 having the second threaded hole is inserted into the limiting groove of the fixing block 8, and the fixing block 8 and the L-shaped block 5 are fixedly connected by screwing the end nut after the second threaded nail 6 passes through the round elastic pad 9 and the second threaded hole. The limiting block 10 is an I-shaped steel structure, one end of which is fixedly connected to the middle of the fixing block 8 through a rectangular groove, and the other end of the rectangular groove is matched with the fixing plate 13 in size; third threaded holes are formed in the surfaces of the two side plates of the rectangular groove, and the elastic piece 11 is fixedly connected to the upper surface; the fixing plate 13 also has third threaded holes, and the fixing plate 13 is inserted into the rectangular groove of the limiting block 10, and the fixing plate 13 and the limiting block 10 are fixed by the third threaded nail 12 passing through the third threaded holes, so as to form a stable connecting and fixing assembly, separate the stone plate 1 from the civil wall surface, and connect the fixing plate 13 with the cross beam and the column to be connected with the wall embedded part, thereby forming a ready-made stone curtain wall. The limiting block 10 is made of a material with excellent corrosion resistance, which is suitable for use in strong corrosive medium and high temperature difference environment.

[0045] The application is characterized in that the T-shaped block 2 with the concave rubber block 3 is slidably arranged in the T-shaped groove of the upper and lower stone plates 1 to connect the longitudinally adjacent stone plates 1 and seal the transverse gap; the limiting pin 14 is screwed into the limiting hole 7 on the surface of the stone plate 1 through the threaded hole on the supporting plate 15 to connect the transversely adjacent stone plates and seal the longitudinal gap through the concave-convex rubber pad 16, so that the stone plates are arranged in order and are stably fixed on the columns and beams through the connecting and fixing assembly and are arranged on the outside of the civil wall through the adapter to form a stone curtain wall, and the sealing of the curtain wall gap is realized. When the rain falls on the stone curtain wall, the T-shaped block 2 with the concave rubber block 3 and the concave-convex rubber pad 16 play a waterproof role to prevent water from penetrating into the gap between the stone plates, and the groove with the concave rubber block 3 fixed on the side of the T-shaped block 2 can be used as a transverse drainage channel to guide the water in the transverse gap into the concave-convex groove of the concave-convex rubber pad 16 between the longitudinal gaps and then vertically downward to realize the dual functions of waterproofing and drainage, effectively prevent rainwater from penetrating and eroding, protect the structural safety of the stone curtain wall and prolong the service life.
