Description
Technical Field
[0001] The utility model relates to an anti-seepage structure for the exterior wall of a building. Background Art
[0002] Existing prefabricated walls usually improve the wall's anti-seepage effect by changing the formula of concrete, and the prefabricated wall usually includes an inner wall and an outer wall. The inner wall is used for pouring and connecting with the internal structure of the prefabricated building, and the outer wall is used for splicing between prefabricated walls. When the existing prefabricated walls are spliced on site, splicing seams will be left between the outer walls. Usually, the construction workers will use extruded boards to fill the seams, and then pour concrete to fill the seams. For example, the anti-leakage structure of a building insulation type exterior wall panel with patent application number CN202121220624.6 can facilitate the connection and fixation between the insulation exterior wall panels through the set fixed plug rods and fixed slots, and the set limit card blocks and limit card slots can fix the connection between the water stop and the insulation exterior wall panel, and further fix the connection between the insulation exterior wall panels through the water stop, so that the insulation exterior wall panels are connected more stably, and there will be no large seams in the insulation exterior wall panels when pasting, thereby preventing rainwater leakage. However, after being exposed to wind and sun for a long time, the waterstop will age and fall off, causing rainwater to leak through the gaps, thus affecting the device's anti-leakage ability.

DETAILED DESCRIPTION
[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0023] Refer to Figure 1-Figure 6As shown in the figure, since rainwater easily penetrates into the interior from the connection of the exterior wall panel 1 in the prior art, thus affecting the living environment or aesthetics, the present utility model provides an anti-seepage structure for the exterior wall of a building, including several exterior wall panels 1. Connection grooves 2 are provided on both sides of the exterior wall panel 1, and adjacent continuous grooves are connected by anti-seepage connectors 3. The connection groove 2 includes a vertical notch 21, and the top view cross-section of the vertical notch 21 is L-shaped. The end face of the vertical notch 21 facing the interior wall extends inward to form a rectangular groove 22, and the rectangular groove 22 extends toward the other side of the exterior wall panel 1 to form a triangular groove 23. The vertical bottoms of the rectangular groove 22 and the triangular groove 23 do not penetrate the bottom of the vertical notch 21, ensuring that the anti-seepage connector 3 can be stuck in the rectangular groove 22 and the triangular groove 23 to prevent it from falling off, realizing the connection between adjacent exterior wall panels 1 and the anti-seepage connector 3. The anti-seepage connector 3 includes a connection part 31 and a water-stop part 32. The connection part 31 is clamped with the connection groove 2. A cavity for placing the water-stop part 32 is provided on the end face of the connection part 31 away from the interior wall. The water-stop part 32 is detachably connected to the cavity, facilitating the disassembly and maintenance of the water-stop part 32 and ensuring the anti-seepage effect at the connection of the exterior wall panel 1.
[0024] Refer to as Figure 3-Figure 5 As shown in the figure, the connection part 31 includes a connecting plate 311 in a shape similar to "凵" that is adapted to the adjacent vertical notch 21. The entire connecting plate 311 fits the vertical notch 21. A rectangular strip 312 corresponding to the rectangular groove 22 is provided on the connecting plate 311. First through grooves 313 are provided on the upper and lower end faces of both sides of the rectangular strip 312 corresponding to the triangular groove 23. A first telescopic member 4 is provided in the first through groove 313. The connecting plate 311 is provided with a slot 315 for driving the first telescopic member 4 corresponding to the first telescopic member 4. The first telescopic member 4 includes triangular blocks 41 that are slidably connected to both ends of the first through groove 313. A rotating rod 42 is threadedly connected between the triangular blocks 41. The first through groove 313 is provided with a limiting ring 43 for restricting the lateral movement corresponding to the rotating rod 42. By rotating the rotating rod 42 exposed at the slot 315, since the triangular blocks 41 are restricted by the first through groove 313 and cannot rotate, when the rotating rod 42 rotates, the triangular blocks 41 will form a linear motion. The threads on both sides of the rotating rod 42 are reverse threads, thereby ensuring that the triangular blocks 41 can move toward the direction of the triangular groove 23, realizing the clamping of the triangular blocks 41 with the triangular groove 23, ensuring that the connecting plate 311 will not come out of the connection groove 2. While strengthening the connection between adjacent exterior wall panels 1, the connecting plate 311 itself also has an anti-seepage effect, providing a preliminary cover for the connection groove 2 of the exterior wall panel 1.
[0025] Refer to as Figure 4As shown, in order to further enhance the anti-seepage effect, a water stop portion 32 is provided, and the water stop portion 32 includes a water stop plate 321. The side wall of the water stop plate 321 corresponds to the card slot 314 set on the left and right side walls of the connecting plate 311 and is provided with a second through groove 322. A second telescopic member 5 is provided in the second through groove 322. The second telescopic member 5 includes a first movable plate 51 and a second movable plate 52 set in the second through groove 322. The end surfaces of the first movable plate 51 and the second movable plate 52 facing the card slot 314 are both provided with a clamping block 53. The clamping block 53 is adapted to the shape of the card slot 314. The first movable plate 51 and the second movable plate 52 are connected to the second through groove 322. 322 is connected by sliding through the guide block and the guide groove. The first moving plate 51 and the second moving plate 52 are provided with single-sided tooth patterns 54 respectively. The single-plate tooth patterns are connected with the rotating part 55. The water stop plate 321 is provided with a through hole 325 corresponding to the rotating part 55. The rotating part 55 includes a gear 551 meshing with the single-sided tooth pattern 54 and a connecting rod 552 connected with the gear 551. The end of the connecting rod 552 is provided with a first protrusion or a first groove of other shapes except the center of the circle, and the length of the connecting rod 552 is shorter than the length of the through hole 325 to prevent the damage between the wall panels caused by the rotation of the connecting rod 552 by the idle personnel. The connecting rod 552 is equipped with a detachable wrench. The wrench is provided with a second groove corresponding to the first protrusion or a second protrusion corresponding to the first groove. The rotation of the connecting rod 552 is achieved by rotating the wrench. The rotating wrench is L-shaped. The end face with the second groove or the second protrusion extends into the through hole 325 and is connected to the end of the connecting rod 552 to achieve the disassembly of the water stop part 32. In order to maintain the beauty of the outer wall, a blocking block with the same color as the outer wall can be inserted into the through hole 325. While maintaining the beauty, the through hole 325 is blocked to prevent rainwater from flowing into the through hole 325.
[0026] Refer to Figure 5 As shown, in order to strengthen the connection tightness and anti-seepage performance between the end face of the water stop plate 321 away from the inner wall and the exterior wall panel 1, a shielding plate 323 is extended from the side of the end face of the water stop plate 321 away from the inner wall, and a sealing strip 324 is vertically embedded or coated with glue on the end face of the shielding plate 323 facing the exterior wall panel 1.
[0027] Working principle: Install the outer wall panel 1 from bottom to top, fix the outer wall panel 1 on the inner wall in order, fix the adjacent outer wall panel 1 on the inner wall, and then vertically insert the connecting plate 311 into the vertical notch 21, and then insert the triangular block 41 into the triangular groove 23 by rotating the first telescopic member 4, or first extend the triangular block 41 when inserting the connecting plate 311, and vertically insert the corresponding vertical notch 21, and after completing the installation of the connecting plate 311, install the water stop 32, and then install the water stop plate 32. 1 is placed toward the cavity of the connection plate 311 to place the water stop plate 321. After placement, the second telescopic member 5 is rotated to engage the clamping block 53 with the clamping groove 314 to realize the connection between the water stop portion 32 and the connection portion 31, thereby completing the anti-seepage treatment of the connection of the exterior wall panel 1. The adjacent exterior wall panels 1 are then installed, and then the anti-seepage connector 3 is connected. The above steps are installed in sequence to realize the installation of the exterior wall surface. When a certain exterior wall panel 1 is damaged, the anti-seepage connectors 3 on both sides are disassembled to replace the damaged exterior wall panel 1. When the water stop portion 32 is damaged or the sealing strip 324 needs to be replaced, it is replaced through the second telescopic member 5, which is convenient for disassembly and installation, avoiding the workload of using a large amount of glue to stick the water stop strip and the problem of reduced anti-seepage effect of the water stop strip after long-term use.
