[0035] Figure 1 Shown in the figure is a schematic diagram of the overall structure of the external wall water guiding device in an embodiment of the present disclosure.

[0036] exist Figure 1In the example, the external wall water guide device includes at least one water guide component 10. The water guide component 10 includes a first water guide pipe 11 and a plurality of second water guide pipes 12.

[0037] The first water conduit 11 is installed on the outer wall in the vertical direction. For example, the first water conduit 11 is formed with a plurality of first mounting holes 1101 spaced apart in the vertical direction on both side walls in the vertical direction, and the first water conduit 11 is mounted to the wall surface by passing bolts or expansion wires through the first mounting holes 1101. For example, the first water conduit 11 is implemented as a rectangular two-way pipe. In another embodiment, the first water conduit 11 may also be implemented as a circular two-way pipe or a two-way pipe of other shapes.

[0038] exist Figure 1 In the example, the plurality of second water pipes 12 are connected to the side wall of the first water pipe 11 at intervals along the vertical direction. And each of the second water pipes 12 extends from high to low relative to the first water pipe 11 in the direction from far to near, that is, each of the second water pipes 12 is connected to the first water pipe 11 in an inclined shape. Preferably, the angle between the second water pipe 12 and the horizontal plane is 5-20 degrees. It can be understood that the inclination angle of the second water pipe 12 is not limited to this. A plurality of water guide holes 1201 are formed on the upper surface of each second water pipe 12, which are distributed at intervals along its length direction. So that the liquid retained in the second water pipe 12 through the water guide holes 1201 can flow into the first water pipe 11 under the action of gravity. Exemplarily, the second water pipe 12 is implemented as a straight pipe. In another embodiment, the second water pipe 12 can also be implemented as an arc-shaped pipe with the arc opening facing the first water pipe 11. In some embodiments, the water guide hole 1201 on the second water guide pipe 12 may also be implemented as one; or the number of the water guide holes 1201 is adaptively adjusted according to the length of the second water guide pipe 12. In another embodiment, water guide holes 1201 may also be formed on other side walls other than the bottom wall of the second water guide pipe 12 to increase the path for collecting liquid in the wall and improve the drainage effect of the wall. Exemplarily, the second water guide pipe 12 is implemented as a rectangular tube. In another embodiment, the second water guide pipe 12 may also be implemented as a circular tube; or a tube of other shapes with a depression formed on the top to collect more liquid in the wall and discharge it through the first water guide pipe 11.

[0039] Figure 2 FIG. 1 is a cross-sectional view of the first water conduit 11 in the embodiment of the present disclosure. Figure 2In the example, a plurality of connecting holes 1102 are respectively formed on the two side walls of the first water conduit 11 perpendicular to the wall surface, which are spaced apart in the vertical direction and are used for inserting the second water conduit 12. Exemplarily, the connecting holes 1102 on both sides of the first water conduit 11 are staggered in the up-down direction, that is, the second water conduits 12 on both sides of the first water conduit 11 are also staggered in the up-down direction. Further exemplarily, the inclination angles of the second water conduits 12 on both sides of the first water conduit 11 are the same. Through the staggered distribution of the connecting holes 1102, it is possible to avoid excessive concentration of stress on the first water conduit 11, thereby improving the overall strength of the first water conduit 11, so as to avoid bending or breaking of the first water conduit 11. In another embodiment, the plurality of second water conduits 12 may also be arranged only on one side wall of the first water conduit 11. In another embodiment, the connecting holes 1102 on both sides of the first water conduit 11 may also be symmetrically or irregularly distributed. Exemplarily, if the second water conduit 12 is rectangular, the communication hole 1102 is also rectangular. In another embodiment, if the second water conduit 12 is circular, the communication hole 1102 is also circular. Exemplarily, both the first water conduit 11 and the second water conduit 12 are made of stainless steel or painted to prevent rust or decay due to long-term use, thereby extending the service life of the water guide component 10.

[0040] Figure 3 FIG. 1 is a cross-sectional view of the second water conduit 12 in the embodiment of the present disclosure. Figure 3 In the example, a plurality of second mounting holes 1202 spaced apart along the length direction are formed at both ends of one of the side walls perpendicular to the side wall where the water guide hole 1201 is located on the second water guide pipe 12. After the mounting angle of the second water guide pipe 12 is adjusted and the second water guide pipe 12 is inserted into the connecting hole 1102, the installer installs the second water guide pipe 12 to the wall surface by passing bolts or expansion wires through the second mounting holes 1202. In another embodiment, the second water guide pipe 12 is inserted into the connecting hole 1102 in an oblique manner and then fixedly installed in the first water guide pipe 11, for example, the second water guide pipe 12 is fixedly installed in the first water guide pipe 11 by welding or bolting, so as to strengthen the overall strength and sealing effect of the water guide assembly 10 and prevent rainwater leakage.

[0041] Figure 4 The figure shows the overall structure of the integrated structure of the external wall drainage system in the embodiment of the present disclosure. Figure 4In the example, the external wall drainage integrated structure is composed of a polymer waterproof mortar layer 20, a water guide component 10, a leveling layer 30 and a thermal insulation finishing layer 40 from the inside to the outside. The polymer waterproof mortar layer 20 includes a first mortar layer 21, a mesh layer 22 and a second mortar layer 23 from the inside to the outside. The first mortar layer 21 is spread on the surface of the external wall (concrete surface), the mesh layer 22 is laid on the surface of the first mortar layer 21, and the second mortar layer 23 is spread on the first mortar layer 21 to cover the mesh layer 22. It can be understood that the provision of the mesh layer 22 can avoid the generation of cracks caused by shrinkage and settlement of the facade base. Exemplarily, the thickness of the first mortar layer 21 and the second mortar layer 23 is 5-12 mm. On the one hand, the polymer waterproof mortar layer 20 plays a role in isolating the intrusion of rainwater. On the other hand, the mesh layer 22 in the polymer water mortar layer 20 effectively resists the cracking and falling of the leveling layer 30 and the thermal insulation finishing layer 40 caused by the cracking of the base layer, and further reduces the penetration of rainwater into the building base along the above defects. Exemplarily, the mesh layer 22 can be implemented as a glass fiber mesh cloth or a galvanized steel wire mesh. In another embodiment, an adhesive material can also be added between the first mortar layer 21 and the mesh layer 22 and the second mortar layer 23 to improve the overall bonding effect inside the polymer waterproof mortar layer 20.

[0042] There is at least one water guide assembly 10, and it is installed on the surface of the second mortar layer 23. Exemplarily, the water guide assembly 10 is implemented as a plurality of water guide assemblies, and the first water guide pipes 11 in the plurality of water guide assemblies 10 are connected in the vertical direction, and the top of the first water guide pipe 11 at the uppermost end is located at the top of the building, and the bottom of the first water guide pipe 11 at the lowermost end is connected to the ground, so that the rainwater in the first water guide pipe 11 flows to the ground. In another embodiment, the bottom of the first water guide pipe 11 at the lowermost end is connected to the sewer. Exemplarily, the water guide assembly 10 is implemented as a plurality of water guide assemblies 10, and the plurality of water guide assemblies 10 are arranged at intervals along the width of the outer wall of the building, and each water guide assembly 10 is connected to a plurality of water guide assemblies 10, so as to be arranged on the outer wall of the building to the maximum extent. For example, if the width between the two first water guide pipes 11 on each of the two adjacent water guide assemblies 10 is 20 meters, then the length of each second water guide pipe 12 should be less than 10 meters. Of course, the distance between the two first water pipes 11 on each two adjacent water guide components 10 and the length of each second water pipe 12 can be adjusted according to the width of the building's outer wall and are not limited to the above distance.

[0043] The leveling layer 30 is spread on the second mortar layer 23 to cover the water guide component 10. For example, when fixing the water guide component 10, the construction personnel can also fix a mesh cloth of a certain area (not shown in the figure) on the outer surface of the water guide component 10 to completely cover the water guide component 10. Since the mesh cloth has a suitable aperture, it can prevent the material of the leveling layer 30 from passing through the holes of the mesh cloth and entering the second water guide pipe 12 and the first water guide pipe 11 through the water guide hole 1201 when the leveling layer 30 is subsequently spread, thereby blocking the second water guide pipe 12 and the first water guide pipe 11, and finally causing the rainwater that has penetrated into the wall structure to be unable to be discharged to the ground or sewer through the water guide component 10; secondly, it can also allow the rainwater that has penetrated into the wall to pass through the mesh cloth into the second water guide pipe 12, and flow into the first water guide pipe 11 and be discharged to the ground. At the same time, the mesh cloth can also improve the adhesion of the leveling layer 30 on the water guide component 10.

[0044] In another embodiment, the mesh cloth may only cover the second water conduit 12. For example, the leveling layer 30 may be constructed in multiple times, and a certain thickness of the leveling layer 30 is constructed each time. In this way, the flatness of the wall surface can be effectively improved to facilitate later construction, but the overall thickness of the leveling layer 30 should not be greater than 20 mm. Secondly, in order to ensure a firm bond between the thermal insulation finishing layer 40 and the leveling layer 30, the surface of the leveling layer 30 is required to be scraped and rubbed, and watering and curing begins after the leveling layer 30 is finally set.

[0045] The leveling layer 30 is implemented as mortar. After rainwater intrudes into the leveling layer 30, the rainwater is accumulated in the super-leveling layer 30 and enters the second water conduit 12 through the water guide hole 1201, and finally is discharged to the outside of the external wall drainage integrated structure through the first water guide pipe 11. It can be understood that the porous structure of the leveling layer 30 stores rainwater like a sponge. Therefore, if there is no drainage facility inside the leveling layer 30, the rainwater stored inside the leveling layer 30 will cause damage to the external wall. Therefore, the water guide component 10 arranged inside the leveling layer 30 can discharge the rainwater inside the leveling layer 30 to the outside, thereby preventing the external wall from being eroded by the rainwater in the leveling layer 30 for a long time, so as to improve the strength and integrity of the building structure.

[0046] The thermal insulation finishing layer 40 includes a thermal insulation layer 41 and an exterior finishing layer 42 from the inside to the outside. The thermal insulation layer 41 is laid on the leveling layer 30. Exemplarily, the construction personnel fix the thermal insulation layer 41 to the leveling layer 30 by a special adhesive or a mechanical fixation method (such as bolt connection). In another embodiment, a moisture-proof layer (such as a waterproof coating) may be further provided between the leveling layer 30 and the thermal insulation layer 41 to isolate rainwater that penetrates into the thermal insulation layer 41 to the outside of the leveling layer 30, thereby improving the waterproof effect of the exterior wall. In another embodiment, the outer side of the thermal insulation layer 41 is reinforced with a glass fiber mesh cloth or a galvanized steel wire mesh and coated with adhesive mortar before the exterior finishing layer 42 is installed.

[0047] The exterior finishing layer 42 is laid on the outer surface of the insulation layer 41. Exemplarily, the exterior finishing layer 42 is implemented as ceramic tiles or real stone paint. Taking ceramic tiles as an example, the ceramic tiles are coated with ceramic tile adhesive on the back and then laid on the leveling layer 30, and finally the overall structure of the exterior wall is completed. At this time, under the action of wind pressure, the rainwater that penetrates the insulation finishing layer 40 penetrates into the leveling layer 30, and the rainwater that penetrates into the leveling layer 30 flows into the second water pipe 12 through the water guide hole 1201 under the action of gravity, and because the second water pipe 12 is in an inclined state, the above rainwater flows into the first water pipe 11, and finally flows downward to the ground or sewer, thereby avoiding the rainwater that penetrates into the wall from being unable to be discharged, and staying in the building for a long time and causing damage to the building wall, thereby causing water seepage or mold inside the building.

[0048] In summary, the disclosed embodiment provides an external wall water guide device and an external wall drainage integrated structure thereof, wherein the external wall water guide device comprises: at least one water guide component. The water guide component comprises a first water guide pipe arranged in a vertical direction; a plurality of second water guide pipes connected to the side wall of the first water guide pipe, and each of the second water guide pipes extends from high to low relative to the first water guide pipe in a direction from far to near; a water guide hole is formed on the upper surface of each second water guide pipe. The external wall drainage integrated structure comprises a polymer waterproof mortar layer laid on the external wall surface; at least one water guide component installed on the polymer waterproof mortar layer; a leveling layer laid on the polymer waterproof mortar layer to cover the water guide component; and a thermal insulation finishing layer laid on the leveling layer. By arranging the external wall water guide device in the external wall structure, rainwater that penetrates into the leveling layer from the external wall surface can be collected through the second water guide pipe and discharged to the ground through the first water guide pipe, thereby preventing rainwater from being inside the building for a long time and causing damage to the building wall, thereby causing water seepage or mold inside the building.

[0049] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
