Description

Technical Field

[0001] The invention relates to the technical field of exterior wall waterproofing, in particular to an exterior wall self-waterproofing structure. Background Art

[0002] With the vigorous development of my country's construction industry, more and more buildings are being built. How to effectively waterproof the exterior walls of buildings is a problem that needs to be solved urgently. The existing technology generally achieves the purpose of waterproofing by applying waterproof coatings on the surface of the exterior walls. However, after a long period of wind and sun, the waterproof coatings will easily fall off, thereby weakening the waterproof effect of the exterior walls.

[0003] To this end, the invention patent with application number CN201410167693.3 discloses an exterior wall waterproof structure, including a polymer cement waterproof coating layer, a woven polyester cloth and a waterproof and crack-resistant mortar layer.

[0050] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] like Figure 1 As shown, a self-waterproof structure of an exterior wall includes a cast-in-place concrete floor slab 2, a cast-in-place concrete inclined beam 1, a brick wall and a plaster mortar 11, wherein the plaster mortar 11 is coated on the surface of the cast-in-place concrete inclined beam 1 and the brick wall.

[0052] The top surface of the cast-in-place concrete inclined beam 1 is higher than the top surface of the cast-in-place concrete floor 2 and is tilted downwardly away from the cast-in-place concrete floor 2, and the bottom surface of the inclined beam is tilted downwardly away from the cast-in-place concrete floor 2. The highest point of the top surface of the inclined beam is 120 mm higher than the top surface of the cast-in-place concrete floor 2, the top surface of the cast-in-place concrete inclined beam 1 is tilted at an angle of 8 degrees, and the bottom surface of the cast-in-place concrete inclined beam 1 is parallel to the top surface of the cast-in-place concrete inclined beam 1 and is also tilted at an angle of 8 degrees.

[0053] The brick wall is arranged between the upper and lower adjacent cast-in-place concrete inclined beams 1, and includes inclined bricks 3 which are sequentially inclined and laid on the top surface or the bottom surface of the inclined beam. The inclined angle of the inclined bricks 3 is the same as the inclined angle of the top surface of the cast-in-place concrete inclined beam 1, and is also inclined at an angle of 8 degrees.

[0054] Compared with the currently used rectangular beams and flat bricks, the exterior wall of the present application can effectively prevent rainwater from penetrating into the wall through its own cast-in-place concrete inclined beams 1 and inclined bricks 3, achieving a good waterproof effect, and will not affect the waterproof performance of the exterior wall due to long-term wind and sun exposure, and can essentially solve the problem of exterior wall waterproofing.

[0055] In order to ensure the safety performance of the wall and achieve the best waterproof effect, the present application has obtained through a large number of experiments that when the top and bottom surfaces of the cast-in-place concrete inclined beam 1 are inclined at an angle of 8 degrees, the inclined bricks 3 are inclined at an angle of 8 degrees in conjunction with the cast-in-place concrete inclined beam 1, and the highest point of the inclined beam top surface is 120 mm higher than the top surface of the cast-in-place concrete floor 2, the waterproof effect is the best and will not have any safety impact on the wall structure. The cast-in-place concrete inclined beam 1 is also embedded with beam steel bars 12, which further improves the safety performance of the cast-in-place concrete inclined beam 1.

[0056] like Figures 2 to 4As shown, when a window needs to be set in the wall, the waterproof performance of the wall where the window is installed also needs to be ensured. The brick wall is provided with a window opening, and the window opening is used to set a window frame 5. The exterior wall self-waterproof structure also includes a precast concrete window lintel 10 obliquely arranged at the window opening and located above the window frame 5, and a precast concrete window sill waterproof board 4 obliquely arranged at the window opening and located below the window frame 5. The precast concrete window lintel 10 and the precast concrete window sill waterproof board 4 are both connected to the window frame 5 through dry hard waterproof mortar 6.

[0057] The precast concrete window lintel 10 has the same tilt angle as the top surface of the cast-in-place concrete inclined beam 1, which is tilted at 8 degrees. The precast concrete window sill waterproofing board 4 has the same tilt angle as the top surface of the cast-in-place concrete inclined beam 1, which is tilted at 8 degrees. Figure 5 As shown, the top surface of the precast concrete window sill waterproof board 4 is provided with a first waterproof surface 41 parallel to the bottom surface of the precast concrete window sill waterproof board 4, a window frame support surface 42 arranged parallel to the bottom surface of the window frame 5, and a second waterproof surface 43 arranged parallel to and higher than the window frame support surface 42, from left to right. The first waterproof surface 41 and the bottom surface of the precast concrete window sill waterproof board 4 are both inclined at an angle of 8 degrees, which has a good waterproof effect. The window frame support surface 42 is used to stably install the window frame 5. The second waterproof surface 43 is set 30 mm higher than the window frame support surface 42, which further improves the waterproof performance of the precast concrete window sill waterproof board 4.

[0058] The purpose of setting the precast concrete window lintel 10 and the precast concrete window sill waterproof board 4 is to fix the window frame 5. The precast concrete window lintel 10 and the precast concrete window sill waterproof board 4 of the structure of the present application, combined with their setting method, make the exterior wall have long-term and efficient waterproof performance.

[0059] In addition, the part of the precast concrete window lintel 10 located on the outer wall is coated with a window lintel outer wall plastering mortar layer, and the part located on the inner wall is coated with a window lintel inner wall plastering mortar layer. The bottom surface of the window lintel outer wall plastering mortar layer is tilted downward with its back to the window frame 5, and the bottom surface of the window lintel inner wall plastering mortar layer can be horizontally arranged, and the highest point of the bottom surface of the window lintel outer wall plastering mortar layer is lower than the lowest point of the bottom surface of the window lintel inner wall plastering mortar layer. This structure can prevent rainwater from penetrating into the wall from the upper part of the window, thereby improving the waterproof performance of the outer wall located at the upper part of the window. The lowest point of the bottom surface of the window lintel outer wall plastering mortar layer is provided with an eagle's beak line 9, which protrudes 6 cm from the lowest point of the bottom surface of the window lintel outer wall plastering mortar layer, and is used to divert rainwater, further improving the waterproof performance of the outer wall located at the upper part of the window.

[0060] The part of the precast concrete window sill waterproof board 4 located on the outer wall is coated with a window sill waterproof board outer wall plaster mortar layer, and the part located on the inner wall is coated with a window sill waterproof board inner wall plaster mortar layer. The top surface of the window sill waterproof board outer wall plaster mortar layer is inclined downward with its back to the window frame 5. The top surface of the window sill waterproof board inner wall plaster mortar layer can be horizontally arranged, and the highest point of the top surface of the window sill waterproof board outer wall plaster mortar layer is lower than the lowest point of the top surface of the window sill waterproof board inner wall plaster mortar layer. This structure can prevent rainwater from penetrating into the wall from the lower part of the window, thereby improving the waterproof performance of the outer wall located at the lower part of the window.

[0061] The connection between the window frame 5 and the window lintel outer wall plastering mortar layer, the window lintel inner wall plastering mortar layer, the window sill waterproof board outer wall plastering mortar layer, and the window sill waterproof board inner wall plastering mortar layer is filled with silicone weather-resistant sealant 7 to prevent rainwater from penetrating into the wall from the connection between the window frame 5 and the window lintel outer wall plastering mortar layer, the window lintel inner wall plastering mortar layer, the window sill waterproof board outer wall plastering mortar layer, and the window sill waterproof board inner wall plastering mortar layer, thereby further improving the waterproof performance of the outer wall at the window. The top surface and two side surfaces of the window opening are embedded with a U-shaped opening waterproof strip 8, which is 1 cm wide and 1 cm deep, and is used to block rainwater infiltration, further reducing the risk of rainwater infiltration of the wall at the window.

[0062] like Figure 6 As shown, a positioning protrusion 32 is provided on a short side of the bottom surface of the inclined brick block 3 so that the inclined brick blocks 3 are located in the same vertical plane after being stacked. The positioning protrusion 32 is provided to facilitate workers to quickly find the position where the inclined brick blocks 3 need to be laid, and prevent the inclined brick blocks 3 from tilting during laying, which causes the wall to fail to meet the construction requirements. On the other hand, it can further improve the stability of the brick wall of the present application and improve the earthquake resistance of the brick wall.

[0063] like Figures 7 to 11 As shown, the exterior wall self-waterproof structure of the present application also includes a waterproof component arranged on the side of the exterior wall away from the interior, and the waterproof component specifically includes a waterproof plate 21 and a waterproof kit 31.

[0064] The waterproof panel 21 includes an integrally formed square inner panel 211, a square outer panel 212 and a hollow connecting column 213. The four corners of the square inner panel 211 are provided with threaded holes for detachable connection with the outer wall. The side length of the square outer panel 212 is smaller than the side length of the square inner panel 211, and its center point coincides with the center point of the square inner panel 211. One axial end of the hollow connecting column 213 is connected to the square inner panel 2118, and the other axial end is connected to the square outer panel 212.

[0065] During the specific installation, first connect the square inner plate 211 of the waterproof panel 21 to the outer wall of the outer wall. A waterproof assembly may include 9 waterproof panels 21. After the 9 waterproof panels 21 are all connected to the outer wall in the order of three rows and three columns, a waterproof kit 31 is installed in the gap between the two square outer plates 212. The length of the waterproof kit 31 can be set according to actual needs.

[0066] The waterproof panel 21 of the present application has a double plate body of a square inner plate body 211 and a square outer plate body 212, and the two plates are separated by a certain distance through a hollow connecting column 213, so that the waterproof panel 21 not only has a double waterproof effect, but also has a certain heat preservation effect. The size of the square outer plate body 212 is smaller than the size of the square inner plate body 211, and this setting structure facilitates the disassembly and assembly of the square inner plate body 211 and the outer wall. After the waterproof panel 21 is installed, the gap between the two adjacent square outer plates 212 is connected through the waterproof kit 31, so that the connection structure of the waterproof panel 21 is more stable, the waterproof and sun-proof effect is better, and the appearance is more fashionable and beautiful.

[0067] The waterproof kit 31 includes a supporting tube body 311 and a tube body clamp 312. The diameter of the supporting tube body 311 is smaller than the distance between the two square outer plates 212 of the adjacent waterproof panel 21. The tube body clamp 312 is symmetrically arranged around the supporting tube body 311 along the central axis of the tube body, and is used to clamp and connect with the edge of the square outer plate 212. The structure of the waterproof kit 31 of the present application structure is firm and stable, and it is very convenient to disassemble and assemble with the square outer plate 212. The tube body clamp 312 is provided with a clamping protrusion that contacts the square outer plate 212, and the edge of the square outer plate 212 is provided with a clamping groove that cooperates with the tube body clamp 312. The clamping protrusion is located in the clamping groove, which further improves the connection stability and connection sealing between the waterproof kit 31 and the waterproof panel 21.

[0068] The above-described embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
