Abstract
Description
Technical Field
[0001] This utility model relates to the field of building waterproofing technology, specifically to an exterior wall waterproofing structure. Background Technology
[0002] The exterior walls of a building are one of its main structural components and require good waterproofing performance to prevent outdoor water from seeping into the interior and causing water leakage or dampness. Existing waterproofing of building exterior walls is generally achieved through passive waterproofing using corresponding waterproof structural layers. This method is prone to failure and leakage, and in extreme situations such as heavy rain, the existing waterproofing capacity of exterior walls is insufficient and cannot meet the needs of users. Utility Model Content
[0003] To address the aforementioned technical problems, an external wall waterproofing structure is provided, which solves the issues of easy failure of the wall waterproofing layer and insufficient waterproofing capacity in extreme weather.
[0004] To achieve the above objectives, the following solution is provided: an external wall waterproofing structure, including a wall, and further including a first waterproofing component, a drainage component, and a second waterproofing component. The first waterproofing component is disposed on the outer surface of the wall, the drainage component is disposed at the first waterproofing component, and the second waterproofing component is disposed on the surface of the drainage component.
[0005] The drainage component includes a cement mortar layer, a diversion module, and a drainage module. The cement mortar layer is laid on the surface of the first waterproof component, the diversion module is embedded in the cement mortar layer, and the drainage module is set on the surface of the cement mortar layer.
[0006] The drainage module is a drainage net, which is attached to the surface of the first waterproof component. The drainage includes a guide net frame, which has a mesh structure and a "C" shaped cross-section. The opening side of the guide net frame faces the side that is perpendicular to the first waterproof component, and the guide net frame is filled with guide filler.
[0007] The drainage module includes several drainage channels and several guide channels. Each drainage channel is vertically opened on the surface of the cement mortar layer, and each guide channel is inclinedly set on the surface of the cement mortar layer. Each guide channel is evenly arranged on both sides of the drainage channel and the guide channel is connected to the drainage channel. The lower end of the drainage channel and the guide channel are connected.
[0008] Furthermore, the flow-guiding filler is made of sintered material or fiber.
[0009] Furthermore, the first waterproof component includes a waterproof membrane and a first waterproof coating.

The drainage net is attached to the surface of the first waterproof coating.
[0010] Furthermore, the second waterproof component is a second waterproof coating, which is applied to the surface of the cement mortar layer and the surface of the drainage channel and the diversion channel.
[0011] Furthermore, both the first and second waterproof coatings are waterproof resin layers.
[0012] The working principle and advantages of this utility model are as follows: This exterior wall waterproof structure forms a double-layer waterproof structure on the wall surface through the first waterproof component and the second waterproof component, reducing the possibility of water seepage into the wall. The drainage module can collect and guide the water splashed onto the wall surface to be discharged, and the diversion module can divert the water that has seeped into the cement mortar layer to be discharged, thereby greatly reducing the possibility of water penetrating the wall and entering the room, and effectively improving the waterproof performance of the wall.

[0018] The following detailed explanation illustrates the specific implementation methods:
[0019] like Figures 1 to 3 As shown:
[0020] An exterior wall waterproofing structure includes a wall 1, and also includes a first waterproofing component, a drainage component, and a second waterproofing component. The first waterproofing component is disposed on the outer surface of the wall 1 for surface waterproofing of the wall 1. The drainage component is disposed at the first waterproofing component. The second waterproofing component is disposed on the surface of the drainage component. The second waterproofing component is used for surface waterproofing of the drainage component. The drainage component is used to drain water received by the wall 1, thereby reducing the possibility of water seepage in the wall 1 due to the failure of the waterproofing layer.
[0021] The drainage component includes a cement mortar layer 4, a diversion module, and a drainage module. The cement mortar layer 4 is laid on the surface of the first waterproof component. The cement mortar layer 4 is used to install or set the diversion module and the drainage module. The diversion module is embedded in the cement mortar layer 4 and is used to divert and discharge water that has seeped into the cement mortar layer 4. The drainage module is set on the surface of the cement mortar layer 4 and is used to collect, guide, and drain water that splashes on the surface of the wall 1.
[0022] The drainage module is a drainage net 7, which is attached to the surface of the first waterproof component. The drainage net 7 can also enhance the adhesion strength of the cement mortar layer 4 laid on the surface of the first waterproof component. The drainage includes a guide net frame 71, which has a mesh structure. The cross-section of the guide net frame 71 is a "C" shape, that is, a tubular structure with an opening on one side. The opening side of the guide net frame 71 faces the side that is closest to the first waterproof component. The guide net frame 71 is filled with a guide filler 72, which can absorb water in the cement mortar layer 4 and guide the water to the guide net frame 71. The guide net frame 71 can then guide the water out. The guide filler 72 is made of sintered material or fiber and has good water conductivity.
[0023] The drainage module includes several drainage channels 6 and several guide channels 61. Each drainage channel 6 is vertically opened on the surface of the cement mortar layer 4, and each guide channel 61 is inclinedly set on the surface of the cement mortar layer 4. Each guide channel 61 is evenly arranged on both sides of the drainage channel 6 and is connected to the drainage channel 6. The drainage channel 6 is connected to the lower end of the guide channel 61. Water splashed on the surface of the wall 1 can enter the drainage channel 6 under the guidance of each guide channel 61 and then be drained away through the drainage channel 6.
[0024] The first waterproof component includes a waterproof membrane 2 and a first waterproof coating 3. The waterproof membrane 2 is attached to the surface of the wall 1, and the surface of the waterproof membrane 2 is coated with the first waterproof coating 3 to form a waterproof layer structure of the wall 1. The drainage net 7 is attached to the surface of the first waterproof coating 3 to facilitate the installation of the drainage net 7.
[0025] The second waterproof component is the second waterproof coating 5, which is applied to the surface of the cement mortar layer 4 and the surfaces of the drainage channel 6 and the diversion channel to prevent water from seeping into the cement mortar layer 4.
[0026] The first waterproof coating 3 and the second waterproof coating 5 are waterproof resin layers, which have good waterproof performance and corrosion resistance.
[0027] The specific implementation process is as follows:
[0028] When this exterior wall waterproofing structure is in operation, if rainwater or other splashing water splashes onto the surface of the wall 1, the second waterproof coating 5 can prevent water from seeping into the cement mortar layer 4. Under the guidance of the various diversion channels 61 on the surface of the cement mortar layer 4, the splashed water is guided to the various drainage channels 6, and the drainage channels 6 can collect and discharge the water, reducing the possibility of water seeping into the cement mortar layer 4.
[0029] If the second waterproof coating layer 5 fails locally due to an accident, some water seeps into the cement mortar layer 4. The water-guiding filler 72 absorbs the water at the opening of the water-guiding mesh 71. Under the adsorption and guiding effect of the water-guiding filler 72, the water enters the water-guiding mesh 71, accumulates in the water-guiding mesh 71, and is conducted to various parts of the water-guiding mesh 71, dispersing and distributing the water, reducing the possibility of local water accumulation and seepage in the wall 1, and thus reducing the possibility of water penetrating the wall 1. If there is too much water in the water-guiding mesh 71, the water will flow to the bottom of the water-guiding mesh 71 under the action of gravity, and then be discharged from the cement mortar layer 4. At the same time, under the action of the first waterproof coating layer 3 and the waterproof membrane 2, it can further prevent water from penetrating into the wall 1.
[0030] This exterior wall waterproofing structure forms a double-layer waterproof structure on the surface of wall 1 through the first waterproofing component and the second waterproofing component, reducing the possibility of water seepage into wall 1. The drainage module can collect and guide water splashed onto the surface of wall 1 to be discharged, and the diversion module can divert water that has seeped into the cement mortar layer 4 to be discharged, thereby greatly reducing the possibility of water penetrating wall 1 and entering the room, and effectively improving the waterproofing performance of wall 1.
