Description

Technical Field

[0001] This utility model relates to the field of building waterproofing, and in particular to a waterproofing structure for building exterior walls. Background Technology

[0002] The primary function of exterior wall waterproofing is to prevent rainwater, snowmelt, condensation, and other external moisture from seeping into the interior of the walls, thus avoiding structural corrosion, steel reinforcement rust, and insulation layer failure caused by long-term water seepage. A good waterproofing system can extend the building's lifespan, reduce maintenance costs, and prevent indoor mold growth and peeling paint, ensuring building safety and living comfort. Furthermore, waterproofing design can improve the building's aesthetic durability, reduce energy loss due to water seepage, and meet the energy-saving and environmental protection requirements of modern architecture.

[0003] A search revealed CN221461677U, which discloses a waterproof and anti-detachment structure for building exterior walls. The structure includes an exterior wall body, a mortar layer fixedly installed on the front side of the exterior wall body, a mesh reinforcement layer fixedly installed on the front side of the mortar layer, and a waterproof board on the front side of the exterior wall body. The waterproof board has multiple grooves on its front side and is fixed to one side of the exterior wall body using locking bolts. This improves the waterproofing effect of the exterior wall body and prevents the mortar layer and mesh reinforcement layer from detaching. The waterproof layer enhances the waterproofing effect of the waterproof board. A waterproof ceramic tile layer is laid on one side of the exterior decorative layer using cement grout. The waterproof ceramic tile layer effectively waterproofs the exterior wall, and the grooves are filled with a waterproof coating to minimize rainwater penetration into the wall. Overall, the waterproof and anti-detachment effect is good. A search revealed CN222295541U, which discloses a structure for an exterior wall waterproofing caulking system, relating to the field of exterior wall waterproofing technology. This exterior wall waterproofing caulking system includes a masonry wall and a plaster layer. The masonry wall is coated with a plaster layer, which is then coated with a waterproof interface layer. A tile adhesive layer is applied to the waterproof interface layer, and a tile back adhesive layer is provided on each tile. The tiles are laid by bonding them together using the tile back adhesive layer and the tile adhesive layer. The gaps between adjacent tiles are filled with a caulking layer. By using a notched scraper to apply a notched texture to the tile adhesive layer and the tile back adhesive layer, the notched grooves of the tile adhesive layer and the tile back adhesive layer interact, thereby improving the full mortar coverage when laying the tiles. The gaps between the tiles are then filled with a caulking layer, making the connection between adjacent tiles and between the tiles and the masonry wall tighter and preventing water leakage, thus achieving a seepage prevention effect.

[0004] While existing technologies can achieve waterproofing of building exterior walls, they also have drawbacks such as water seepage through gaps during the installation of existing curtain wall glass, poor drainage, and structural damage caused by thermal deformation. In view of this, we propose a waterproofing structure for building exterior walls that solves the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a waterproof structure for building exterior walls.

[0006] The technical solution of this utility model is as follows: a waterproof structure for building exterior walls, including a mounting frame, a channel one and a channel two. The surface of the mounting frame is embedded with recessed grooves arranged in a square array. The transverse mounting frame positions between the recessed grooves are provided with channel two. The longitudinal mounting frame positions between the recessed grooves are provided with channel one. The intersection of channel one and channel two is designed in a cross shape. When using this device, the mounting bracket is installed on the exterior wall. After it is fixed in place, the tempered glass of the curtain wall is embedded in the recessed groove. The gaps between the glass do not need to be waterproofed. When it rains, water flowing down the exterior wall will enter the groove through the gaps. The water will then fall into channel two along the inclined groove and flow down the mounting bracket from channel two. Channel one is also designed with an inclination. When channel two is blocked, channel one can serve as a last resort for drainage. When channel two is draining, the opening in channel one can provide a pressure balancing effect for channel two. This device has multiple drainage channels, so that even if water seeps into the interior of the wall, it can be discharged from channel one or channel two, providing a good waterproof effect.

[0007] Preferably, the longitudinal depth of the recess is three centimeters, and through holes distributed in a linear array are provided on both sides of the mounting bracket. These through holes are used to reduce thermal deformation. The recess depth of three centimeters ensures stable glass mounting while avoiding excessive depth that could affect structural strength. The through holes on both sides of the recess effectively disperse thermal stress, reduce structural deformation caused by temperature changes, and improve the durability and stability of the mounting bracket, making it suitable for long-term use under different climatic conditions.

[0008] Preferably, the channel is designed with an angle of 5 degrees west of south. One end of the channel is connected to the outer wall of the mounting frame. The 5-degree west-south inclination of the channel, combined with the structure of penetrating the outer wall of the mounting frame, ensures that water flows naturally to the outside under the action of gravity, avoiding internal water accumulation. This angle optimizes the drainage path and is especially suitable for multi-wind, multi-rain environments, enhancing drainage adaptability.

[0009] Preferably, the diameter of the second channel is larger than that of the first channel. The uppermost and lowermost ends of the second channel pass through the mounting frame, with the upper end being the inlet and the lower end being the outlet. The larger diameter of the second channel improves the discharge capacity of large-volume rainwater. The design of the upper and lower ends passing through the mounting frame forms a continuous drainage path. The clear distinction between the inlet and outlet further optimizes the water flow direction, prevents backflow, and ensures efficient drainage.

[0010] Preferably, the lower end of the settling tank has a groove with a centered inclined design at an angle of five degrees. The lowest end of the groove is connected to the second channel. The five-degree inclined groove design at the bottom of the settling tank precisely guides the water flow to the second channel, avoiding local water accumulation. The connection structure between the groove and the second channel simplifies the drainage path, reduces the risk of stagnation, and further improves the reliability and maintenance convenience of the waterproof system.

[0011] Compared with existing technologies, the advantages of this utility model are: I. This utility model achieves multiple drainage and anti-clogging functions through a unique cross-shaped channel design and inclined groove structure; Channel 1 and Channel 2 can not only drain water independently, but also provide emergency drainage through Channel 1 when Channel 2 is blocked. At the same time, the opening of Channel 1 provides air pressure balance for Channel 2, avoiding drainage obstruction due to negative pressure; in addition, the through hole design on both sides of the settling tank effectively reduces the impact of thermal deformation on the mounting bracket and extends its service life.

[0012] II. Based on the first beneficial effect, the drainage system design of this utility model significantly improves the waterproof performance of the curtain wall. Traditional curtain walls rely on sealant for waterproofing, which is prone to aging and cracking after long-term use, leading to water seepage problems. This utility model, however, directly drains infiltrated water through physical drainage channels, eliminating the need for sealing materials and solving the fundamental defects of traditional technologies. Furthermore, the inclined angle of channel one (5 degrees west of south) and the larger diameter design of channel two further optimize drainage efficiency, ensuring rapid water discharge and preventing water accumulation from eroding the wall. The inclined design of the groove (5 degrees) guides water precisely into channel two, reducing the risk of stagnation. This multi-layered protection mechanism enables this utility model to maintain excellent waterproof performance even under extreme weather conditions.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Example 1 Please see Figures 1-4 As shown, this embodiment is a waterproof structure for building exterior walls, including a mounting frame 1, a channel 1 6 and a channel 2 7. The surface of the mounting frame 1 is embedded with recessed grooves 3 arranged in a square array. The horizontal mounting frame 1 positions between the recessed grooves 3 are provided with channel 2 7, and the vertical mounting frame 1 positions between the recessed grooves 3 are provided with channel 1 6. The intersection of channel 1 6 and channel 2 7 is designed in a cross shape. When using this device, the mounting bracket 1 is installed on the exterior wall. After it is fixed, the tempered glass of the curtain wall is embedded in the recessed groove 3. The gaps between the glass do not need to be waterproofed. When it rains, water flows down the exterior wall and enters the groove 5 through the gaps. The water then falls into the second channel 7 along the inclined groove 5 and flows down the mounting bracket 1 from the second channel 7. The first channel 6 is also designed to be inclined. When the second channel 7 is blocked, the first channel 6 can be used as a last resort for drainage. When the second channel 7 is draining, the opening of the first channel 6 can provide a pressure balancing effect for the second channel 7. This device has multiple drainage channels, so that even if water seeps into the interior of the wall, it can be discharged from the first channel 6 or the second channel 7, which has a good waterproof effect.

[0021] Example 2 Please see Figures 1-4 As shown, this embodiment, based on embodiment 1, further includes: a mounting frame 1, a channel 1 6 and a channel 2 7. The surface of the mounting frame 1 is embedded with recesses 3 arranged in a square array. The transverse mounting frame 1 positions between the recesses 3 are provided with channels 2 7. The longitudinal mounting frame 1 positions between the recesses 3 are provided with channels 1 6. The intersection of channels 1 6 and channels 2 7 is designed in a cross shape. The recess 3 has a longitudinal depth of three centimeters. Through holes 4 arranged in a linear array are provided on both sides of the mounting bracket 1. These through holes 4 are used to reduce thermal deformation. The three-centimeter depth of the recess 3 ensures stable glass mounting while avoiding excessive depth that could compromise structural strength. The through holes 4 on both sides of the recess 3 effectively disperse thermal stress, reduce structural deformation caused by temperature changes, and improve the durability and stability of the mounting bracket 1, making it suitable for long-term use under various climatic conditions.

[0022] Channel 1-6 is designed with an angle of 5 degrees west of south. One end of Channel 1-6 is connected to the outer wall of the through-mounting frame 1. The 5-degree west-southwest inclination of Channel 1, combined with the structure of the through-mounting frame 1, ensures that water flows naturally to the outside under gravity, avoiding internal water accumulation. This angle optimizes the drainage path and is especially suitable for multi-wind, multi-rain environments, enhancing drainage adaptability.

[0023] The diameter of channel 2 7 is larger than that of channel 1 6. The uppermost and lowermost ends of channel 2 7 pass through the mounting frame 1, with the upper end being the inlet 2 and the lower end being the outlet. The larger diameter of channel 2 7 improves the discharge capacity of large-volume rainwater. Its design of passing through the mounting frame 1 from top to bottom forms a continuous drainage path. The clear distinction between the inlet 2 and the outlet further optimizes the water flow direction, prevents backflow, and ensures efficient drainage.

[0024] The lower end of the sedimentation tank 3 has a groove 5. The groove 5 is centered and inclined at five degrees. The lowest end of the groove 5 is connected to the second channel 7. The five-degree inclined groove 5 at the bottom of the sedimentation tank 3 is designed to precisely guide the water flow to the second channel 7, avoiding local water accumulation. The connection structure between the groove 5 and the second channel 7 simplifies the drainage path, reduces the risk of stagnation, and further improves the reliability and maintenance convenience of the waterproof system.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
