Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a prefabricated waterproof board for exterior walls. Background Technology

[0002] Building exterior wall waterproofing boards refer to the boards that cover the outside of building walls to provide waterproofing. At the same time, exterior wall waterproofing boards can also slow down the weathering of the walls and extend the service life of the building.

[0003] Currently, Chinese utility model patent CN213539338U discloses a prefabricated waterproof structure for building exterior walls, including exterior wall panels. A base is provided between two sets of adjacent exterior wall panels. The left and right sides of the back of the base are fixedly connected to the front sides of the two sets of exterior wall panels, respectively. The middle of the front side of the exterior wall panel is fixedly connected to the rear side of a flow guide seat, which includes a guide shell. This prefabricated waterproof structure for building exterior walls, through the cooperation of the guide shell, sloping top, water inlet trough, flow guide trough, and inspection plate, facilitates the diversion of rainwater and the maintenance of the flow guide seat, improving the ease of use of the device. Through the cooperation of the water absorption plate, mounting shell, exterior wall panels, connecting plate, and base, the prefabricated waterproof structure for building exterior walls effectively prevents water droplets from entering the gaps between the two sets of exterior wall panels, improving the safety of the building.

[0004] Existing exterior wall waterproofing membrane installations generally require the use of fasteners to fix the membrane to the wall. Common fasteners are screws or rivets. However, regardless of the installation method, holes need to be drilled inside the membrane before screws or rivets are used to nail it to the wall. This installation method leaves the fasteners exposed, making them prone to water accumulation and corrosion, which can lead to them becoming locked and difficult to remove. At the same time, although existing exterior wall waterproofing membranes are waterproof, rainwater dripping onto them causes it to scatter and drip, making it difficult to collect and treat or recycle rainwater, resulting in low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated waterproof board for exterior walls, which has the advantages of preventing fasteners from being exposed to water and rusting, and facilitating the guidance and collection of rainwater.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a prefabricated exterior wall waterproofing panel, comprising an exterior wall and a waterproofing panel installed on one side of the exterior wall, wherein a groove is provided on the side of the waterproofing panel near the exterior wall, a C-shaped fixing rod is provided inside the groove and fixedly connected to the exterior wall, a T-shaped clamping plate is provided inside the C-shaped fixing rod and fixedly connected to the waterproofing panel, and two spring pieces that are clamped to the C-shaped fixing rod are symmetrically fixedly connected on the side of the T-shaped clamping plate near the waterproofing panel, and both spring pieces are fixedly connected to the T-shaped clamping plate at one end.

[0007] The above technical solution utilizes a T-shaped clamping plate and spring sheets to press against a C-shaped fixing rod. The spring sheets' rebound force after contraction, combined with the friction generated by pressing the C-shaped fixing rod, secures the waterproof membrane. This facilitates the assembly and splicing of the waterproof membrane. Simultaneously, the mounting components are located inside the waterproof membrane, effectively preventing them from being exposed to rainwater erosion and facilitating disassembly and replacement. Water is guided by the beveled surfaces at both ends of the arrow groove to the drainage hole grooves on both sides, dripping downwards. Water droplets sliding down the front of the waterproof membrane can extend downwards through the beveled protrusions at both ends of the dovetail groove bottom, using the surface tension between the droplets and the dovetail groove surface to slide into the drainage hole groove and drip downwards. This design effectively guides and concentrates rainwater, facilitating rainwater treatment or recycling and improving the practicality of the waterproof membrane.

[0008] The present invention is further configured such that: an arrow groove is provided at the top of the waterproof membrane, a dovetail groove is provided at the bottom of the waterproof membrane, and a matching slope is provided at the top of the arrow groove and the bottom of the dovetail groove; the slopes of the arrow groove and the dovetail groove are inclined downwards towards the end away from the outer wall; and guide hole grooves are provided on both sides of the waterproof membrane away from the outer wall.

[0009] The above technical solution facilitates the guidance and concentration of rainwater, making it easier to treat or recycle rainwater and improving the practicality of the waterproof membrane.

[0010] The present invention is further configured such that a dustproof membrane is fixedly connected to the surface of the waterproof membrane.

[0011] By adopting the above technical solution, dust adhering to the surface of the waterproof membrane is reduced, and the cleanability of the waterproof membrane is improved.

[0012] The present invention is further configured such that: a trapezoidal protrusion is provided inside the C-shaped fixing rod.

[0013] By adopting the above technical solution, the friction between the spring sheet and the C-shaped fixing rod is increased, thereby increasing the stability of the clamping.

[0014] The present invention is further configured such that: the interior of the C-shaped fixing rod is slidably connected with an installation bolt that is threadedly connected to the exterior wall.

[0015] Using the above technical solution, the C-shaped fixing rod can be pre-installed and fixed on the side of the exterior wall by using mounting bolts.

[0016] The present invention is further configured such that: a dovetail protrusion is fixedly connected to the bottom of the waterproof plate to cooperate with the dovetail groove.

[0017] By adopting the above technical solution, the sliding water droplets can be blocked, thereby allowing them to slide inside the guide hole groove and further improving the concentration of water droplet sliding.

[0018] The present invention is further configured such that sealing plugs that are inserted into the same groove are installed on both sides of the waterproof membrane.

[0019] By adopting the above technical solution, both ends of the groove can be sealed, thereby preventing rainwater and dust from entering the interior from both ends.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. The waterproof membrane is secured by using a T-shaped clamp and spring plates to squeeze into the C-shaped fixing rod. The spring plates' rebound force after contraction and the friction generated by squeezing the C-shaped fixing rod make it easy to splice and assemble the waterproof membrane. At the same time, the mounting parts are located inside the waterproof membrane, which can effectively prevent the mounting parts from being exposed to rainwater erosion and facilitate disassembly and replacement.

[0022] 2. Water is guided by the inclined surfaces at both ends of the arrow groove to drip downwards into the drainage hole grooves on both sides. At the same time, water droplets sliding down the front of the waterproof membrane can extend downwards through the two ends of the dovetail groove to the inclined protrusion inside the drainage hole groove. The tension between the water droplets and the surface of the dovetail groove allows the water droplets to slide into the drainage hole groove and drip downwards. This design facilitates the guidance and concentration of rainwater, making it easier to treat or recycle rainwater and improving the practicality of the waterproof membrane.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A prefabricated exterior wall waterproofing panel includes an exterior wall 1 and a waterproofing panel 2 installed on one side of the exterior wall 1. A groove 3 is formed on the side of the waterproofing panel 2 near the exterior wall 1. A C-shaped fixing rod 4, fixedly connected to the exterior wall 1, is installed inside the groove 3. A T-shaped clamping plate 5, fixedly connected to the waterproofing panel 2, is installed inside the C-shaped fixing rod 4. Two spring pieces 6, which are engaged with the C-shaped fixing rod 4, are symmetrically fixedly connected to the side of the T-shaped clamping plate 5 near the waterproofing panel 2. Both spring pieces 6 are fixedly connected to the T-shaped clamping plate 5 at one end. The T-shaped clamping plate 5 utilizes the spring pieces 6 to squeeze into the C-shaped fixing rod 4, causing the spring pieces 6 to retract and the friction generated by squeezing the C-shaped fixing rod 4 to secure the waterproofing panel 2. This design facilitates the assembly of the waterproofing panel. Furthermore, the installation components are located inside the waterproofing panel, effectively preventing them from being exposed to rainwater erosion and facilitating disassembly and replacement.

[0031] refer to Figure 3 , Figure 4 The C-shaped fixing rod 4 has a trapezoidal protrusion 11 inside, which increases the friction between the spring plate 6 and the C-shaped fixing rod 4, thereby increasing the stability of the clamping.

[0032] refer to Figure 2 , Figure 4 The C-shaped fixing rod 4 has a sliding connection inside with a mounting bolt 12 that is threaded to the outer wall 1. The C-shaped fixing rod 4 can be pre-installed and fixed on the side of the outer wall 1 by using the mounting bolt 12.

[0033] refer to Figure 1 Both sides of the waterproof membrane 2 are equipped with sealing plugs 14 that are inserted into the groove 3, which can seal the two ends of the groove 3, thereby preventing rainwater and dust from entering the interior from the two ends.

[0034] Brief description of the usage process: Fix the C-shaped fixing rod 4 to one side of the outer wall 1 using the mounting bolts 12. Then, slide the T-shaped clamping plate 5 into the interior of the C-shaped fixing rod 4 from either side of the C-shaped fixing rod 4, so that the spring plate 6 fits and is fixed to the interior of the T-shaped clamping plate 5. Then, push the waterproof plate 2 to make the T-shaped clamping plate 5 slide into the C-shaped fixing rod 4. The trapezoidal protrusion 11 inside the C-shaped fixing rod 4 squeezes the spring plate 6, causing the spring plate 6 to contract and rebound to squeeze the C-shaped fixing rod 4. Through the rebound force of the spring plate 6 after contraction and the friction force of squeezing the C-shaped fixing rod 4, the waterproof plate 2 is slowly fixed to the wall surface of the outer wall 1 during the sliding of the T-shaped clamping plate 5.

[0035] Example 2

[0036] refer to Figure 1 , Figure 2 A prefabricated exterior wall waterproofing board 2 has an arrow groove 7 at the top and a dovetail groove 8 at the bottom. Both the top of the arrow groove 7 and the bottom of the dovetail groove 8 have matching slopes, with the slopes of both sloping downwards towards the end furthest from the exterior wall 1. Water is guided by flow-guiding grooves 9 on both sides of the waterproofing board 2 furthest from the exterior wall 1. Water is guided to the flow-guiding grooves 9 by the slopes at both ends of the arrow groove 7 and drips downwards. Simultaneously, water droplets sliding down the front of the waterproofing board 2 can extend downwards through the sloped protrusions at both ends of the bottom of the dovetail groove 8 into the flow-guiding groove 9. Utilizing the surface tension between the water droplets and the dovetail groove 8, the water droplets slide into the flow-guiding groove 9 and drip downwards. This design facilitates the guidance and concentration of rainwater, making it easier to treat or recycle rainwater and improving the practicality of the waterproofing board.

[0037] refer to Figure 2 , Figure 4 A dustproof membrane 10 is fixedly connected to the surface of the waterproof membrane 2 to reduce dust on the surface of the waterproof membrane 2 and improve the cleanliness of the waterproof membrane 2.

[0038] refer to Figure 1 , Figure 2 The bottom of the waterproof membrane 2 is fixedly connected with a dovetail protrusion 13 that works in conjunction with the dovetail groove 8. This protrusion can block the water droplets from sliding down, allowing them to slide inside the guide hole groove 9 and further improve the concentration of the water droplets.

[0039] Brief description of the usage process: Arrow grooves 7 and dovetail grooves 8 are respectively opened at the top and bottom of the waterproof membrane 2. At the same time, the top of the arrow groove 7 and the bottom of the dovetail groove 8 are both sloped, and the slopes are all inclined downwards towards the end away from the outer wall 1. So when water drips onto the top of the waterproof membrane 2, the water can be guided to both sides through the arrow grooves 7 and drip from the inside of the guide hole groove 9. At the same time, after the water droplets slide down from the front of the waterproof membrane 2, they can slide into the guide hole groove 9 through the inclined protrusions at both ends of the bottom of the dovetail groove 8. Thus, the water droplets slide into the guide hole groove 9 and fall down through the tension between the water droplets and the surface of the dovetail groove 8.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
