Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically to a water-proof structure for building exterior walls. Background Technology

[0002] During construction, the exterior walls of buildings serve to bear loads and protect against wind and rain. Most existing buildings are formed by pouring reinforced concrete. In order to waterproof the exterior walls, a waterproof layer is installed on the outside of the exterior walls during construction to prevent rainwater and other water bodies from entering the building.

[0003] In existing technologies, after the construction of building exterior walls is completed, multiple layers such as waterproof layer and paint layer are installed on the outside of the building exterior walls. The existing building exterior walls only protect against water seepage through the waterproof layer. On rainy days, due to the poor flatness of the outermost layer of the building exterior wall, rainwater adheres to the outermost layer of the building exterior wall for a long time. When the rainwater adheres to the building exterior wall for a long time, it will gradually penetrate the outermost layer of the building exterior wall and the waterproof layer, resulting in poor waterproofing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof structure for building exterior walls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for building exterior walls, comprising an exterior concrete wall, a waterproof layer provided on the outer side of the exterior concrete wall, a raised plate provided on the inner side of the outer side of the waterproof layer, the raised plate protruding from the waterproof layer, a coating layer provided on the outer side of the waterproof layer, the coating layer covering the raised plate, the coating layer having a protrusion at the position corresponding to the raised plate as a flow guiding protrusion, and a sliding plate provided on the outermost side of the exterior concrete wall, the sliding plate being inclined.

[0006] As a further preferred embodiment of this technical solution, a leveling layer is provided between the external concrete wall and the waterproof layer.

[0007] As a further preferred embodiment of this technical solution, the protruding plates are arranged in an alternating pattern.

[0008] As a further preferred embodiment of this technical solution, one end of the slip plate passes through the coating layer and is located inside the waterproof layer.

[0009] As a further preferred embodiment of this technical solution, expansion bolts are installed on the sliding plate, which pass through the leveling layer and the waterproof layer, and the sliding plate is fixedly connected to the external concrete wall through the expansion bolts.

[0010] As a further preferred embodiment of this technical solution, the waterproof layer is polymer cement mortar.

[0011] As a further preferred embodiment of this technical solution, the tilt angle of the sliding plate is 30°.

[0012] This utility model provides a waterproof structure for building exterior walls, which has the following beneficial effects:

[0013] (1) This utility model uses rainwater dripping onto the surface of the building exterior wall. The rainwater on the surface of the coating layer will fall for a period of time under the action of gravity. The rainwater will be blocked and diverted to one place by the guide protrusion, preventing the rainwater from adhering to the coating layer on the exterior concrete wall for a long time. This is used to protect the coating layer while improving the waterproof layer's anti-seepage performance of the exterior concrete wall.

[0014] (2) When the rainwater is blocked and diverted to one place by the guide protrusion, the collected rainwater will drip or flow onto the inclined surface of the slide plate. The rainwater will flow out of the coating layer along the inclined surface of the slide plate, which is used to keep the rainwater on the building exterior wall for a long time, thereby indirectly improving the waterproof performance of the exterior concrete wall.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a waterproof structure for a building exterior wall includes an exterior concrete wall 1. A waterproof layer 2 is provided on the outer side of the exterior concrete wall 1. A raised plate 3, made of wood, is provided inside the outer side of the waterproof layer 2. The raised plates 3 are arranged in a staggered pattern and protrude from the waterproof layer 2. A paint layer 4 is provided on the outer side of the waterproof layer 2, covering the raised plates 3. A guide protrusion 5 is protruding from the paint layer 4 at positions corresponding to the raised plates 3. A sliding plate 6 is provided on the outermost side of the exterior concrete wall 1. The sliding plate 6 is inclined, with one end passing through the paint layer 4 and located inside the waterproof layer 2. The inclination angle of the sliding plate 6 is 30°. Expansion bolts 8 are installed on the sliding plate 6. The expansion bolts 8 pass through the leveling layer 7 and the waterproof layer 2. The sliding plate 6 is fixedly connected to the exterior concrete wall 1 by the expansion bolts 8. When it rains, the rainwater adhering to the surface of the paint layer 4 will fall for a period of time under the action of gravity. The rainwater will be blocked and diverted to one place by the guide protrusions 5, preventing the rainwater from adhering to the paint layer 4 on the exterior concrete wall 1 for a long time. This protects the paint layer 4 and improves the waterproof performance of the waterproof layer 2 to the exterior concrete wall 1. When the rainwater is blocked and diverted to one place by the guide protrusions 5, the collected rainwater will drip or flow onto the inclined surface of the sliding plate 6. The rainwater will flow out of the paint layer 4 along the inclined surface of the sliding plate 6, which is used to prevent the rainwater from staying on the building exterior wall for a long time, indirectly improving the waterproof performance of the exterior concrete wall 1.

[0022] like Figures 1 to 4 As shown, a leveling layer 7 is provided between the external concrete wall 1 and the waterproof layer 2.

[0023] By applying a leveling layer 7 to the surface of the exterior concrete wall 1, the surface of the exterior concrete wall 1 can be made smooth, which is used for subsequent smoothing and application of the waterproof layer 2, so as to achieve effective waterproofing of the exterior concrete wall 1 by the waterproof layer 2.

[0024] like Figures 1 to 4 As shown, the waterproof layer 2 is polymer cement mortar.

[0025] The use of a polymer cement mortar waterproof layer 2 can improve the adhesion strength of this waterproof layer 2 on the building exterior wall.

[0026] This utility model provides a waterproof structure for building exterior walls, and its working principle is as follows:

[0027] When the device is in use, a leveling layer 7 is applied to the outside of the concrete wall 1, and then a waterproof layer 2 is applied to the leveling layer 7. At the same time, a protruding plate 3 is embedded inside the waterproof layer 2 to fix the position of the protruding plate 3. Then, a paint layer 4 is applied to the outside of the waterproof layer 2 and wraps the protruding plate 3. At the position of the protruding plate 3, the paint layer 4 will protrude in the shape of a guide protrusion 5. A vertical installation space for the sliding plate 6 is reserved at the position of the waterproof layer 2 and the paint layer 4. The sliding plate 6 is fixed to the concrete wall 1 by expansion bolts 8.

[0028] When it rains, the rainwater adhering to the surface of the coating layer 4 will fall for a period of time under the action of gravity. The rainwater will be blocked and diverted to one place by the guide protrusions 5, preventing the rainwater from adhering to the coating layer 4 on the exterior concrete wall 1 for a long time. This protects the coating layer 4 and improves the waterproof performance of the waterproof layer 2 on the exterior concrete wall 1. When the rainwater is blocked and diverted to one place by the guide protrusions 5, the collected rainwater will drip or flow onto the inclined surface of the sliding plate 6. The rainwater will flow out of the coating layer 4 along the inclined surface of the sliding plate 6, which prevents the rainwater from staying on the building exterior wall for a long time and indirectly improves the waterproof performance of the exterior concrete wall 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
