Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, specifically a waterproof and leak-proof structure for the exterior walls of old residential communities. Background Technology
[0002] Exterior wall waterproofing is a sub-project that ensures the structure of a building (structure) is protected from water intrusion and the interior space is protected from water damage. Exterior wall waterproofing plays a crucial role in the entire construction project. It involves various exterior wall structures such as basement walls and residential exterior walls. Its function is to prevent rainwater and domestic water leakage and groundwater erosion within the design lifespan of the building or structure, ensuring that the building structure and interior space are not damaged, and providing people with a comfortable and safe living environment.
[0003] In some older residential buildings, due to years of disrepair, the mortar plaster layer on the top floor of the building may crack, creating gaps between the internal and external insulation and the wall. When it rains, rainwater can seep into the gaps between the insulation and the wall and cannot be drained. As the rainwater accumulates, the wall becomes damp, causing the latex paint in the residents' homes to peel and crack, and wooden furniture to rot, resulting in damage to the residents' houses. Utility Model Content
[0004] The purpose of this utility model is to provide a waterproof and leak-proof structure for the exterior walls of old residential buildings, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to a waterproofing and leak-proofing structure for the exterior walls of old residential communities, comprising:
[0006] The wall has an external insulation layer fixedly installed on its outer side and an internal insulation layer fixedly installed on its inner side.

The lead screw is rotatably connected in the circular hole, and the threaded plate is threadedly connected to the lead screw. The threaded plate slides in the slide rail.
[0009] Furthermore, a circular plate is fixedly connected to the end of the lead screw, a hexagonal groove is formed on the surface of the circular plate, and a waterproof plug is embedded and fixed on the top surface of the circular plate.
[0010] Furthermore, a lower sealing plate is fixedly connected to the bottom of the lower inclined plate, and one side of the lower sealing plate is fixedly connected to the outer insulation layer. The bottom surface of the lower sealing plate is an upward inclined surface, and a drip groove is provided on the outer side of the inclined surface of the bottom surface of the lower sealing plate.
[0011] Furthermore, a lower hanging plate is fixedly connected to one side of the bottom surface of the upper inclined plate, and sealant is filled and fixed between the bottom of the lower hanging plate and the top surface of the lower inclined plate. An arc plate is fixedly connected to the bottom of the other side of the upper inclined plate, and a protruding column is fixed to the end of the arc plate. A fixing groove is opened on the surface of the inner insulation layer, and the protruding column is fixed in the fixing groove.
[0012] Furthermore, a first lower connecting plate and a second lower connecting plate are fixedly connected to both ends of the lower inclined plate, and a first upper connecting plate and a second upper connecting plate are fixedly connected to both ends of the upper inclined plate. The first lower connecting plate at one end of the lower inclined plate is fixedly connected to the second lower connecting plate at one end of the adjacent lower inclined plate, and the first upper connecting plate at one end of the upper inclined plate is fixedly connected to the second upper connecting plate at one end of the adjacent upper inclined plate.
[0013] Furthermore, the surface of the first lower connecting plate is provided with multiple sliding grooves, and a lower water interception ditch is provided on one side of the first lower connecting plate.

[0030] 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.
[0031] Please see Figure 1-5As shown, this utility model is a waterproofing and leak-proofing structure for the exterior walls of old residential buildings, comprising:
[0032] The wall 100 has an external insulation layer 110 fixed on its outer side and an internal insulation layer 120 fixed on its inner side.
[0033] Waterproof structure, which includes lower inclined plate 200, upper inclined plate 300, and threaded rod 400;
[0034] The lower inclined plate 200 is fixedly connected to the top of the wall 100. A water baffle 250 is fixedly connected to the middle of the lower inclined plate 200. A threaded plate 260 is fixedly connected to the top middle of the water baffle 250. A circular hole 350 is opened in the middle of the upper inclined plate 300. A slide rail 360 is opened at the bottom of the circular hole 350. A screw rod 400 is rotatably connected in the circular hole 350. The threaded plate 260 is threadedly connected to the screw rod 400. The threaded plate 260 slides in the slide rail 360. According to the outer insulation layer 110, the wall 100 and the inner... The overall width of the insulation layer 120 is determined by rotating the lead screw 400, which causes the threaded plate 260 to slide within the slide rail 360. The threaded plate 260 causes the water baffle 250 to slide, and the water baffle 250 causes the lower inclined plate 200 to slide, so that the width between the lower inclined plate 200 and the upper inclined plate 300 is equal to the overall width of the wall 100, the outer insulation layer 110, and the inner insulation layer 120. Then, the lower inclined plate 200 and the upper inclined plate 300 are fixed to the wall 100, the outer insulation layer 110, and the inner insulation layer 120.
[0035] A circular plate 410 is fixedly connected to the end of the lead screw 400. A hexagonal groove 420 is opened on the surface of the circular plate 410. A waterproof plug 500 is embedded and fixed on the top surface of the circular plate 410. After inserting a hexagonal screwdriver into the hexagonal groove 420, the circular plate 410 is rotated, which drives the lead screw 400 to rotate. The waterproof plug 500 prevents rainwater from entering between the upper inclined plate 300 and the lower inclined plate 200 through the circular hole 350 and flowing into the gap between the wall 100 and the outer insulation layer 110 and the inner insulation layer 120.
[0036] The bottom of the lower inclined plate 200 is fixedly connected to the lower sealing plate 230. One side of the lower sealing plate 230 is fixedly connected to the outer insulation layer 110. The bottom surface of the lower sealing plate 230 is an upward slope. A drip groove 240 is opened on the outer side of the bottom slope of the lower sealing plate 230. Rainwater flows down the slope of the upper inclined plate 300 to the slope of the lower inclined plate 200, and then flows down the lower inclined plate 200 to drip into the drip groove 240.
[0037] A lower hanging plate 330 is fixedly connected to one side of the bottom surface of the upper inclined plate 300. A sealant 600 is filled and fixed between the bottom of the lower hanging plate 330 and the top surface of the lower inclined plate 200. The sealant 600 fills the gap between 200 and 300 to prevent rainwater from entering. An arc plate 340 is fixedly connected to the bottom of the other side of the upper inclined plate 300. A protruding post 341 is fixed at the end of the arc plate 340. A fixing groove 121 is opened on the surface of the inner insulation layer 120. The protruding post 341 is fixed in the fixing groove 121, so that rainwater flows down the arc plate 340 to the inner insulation layer 120. The protruding post 341 is inserted into the fixing groove 121 to block the rainwater from flowing down and prevent rainwater from penetrating into the gap between the upper inclined plate 300 and the inner insulation layer 120.
[0038] Working principle: Based on the overall width of the outer insulation layer 110, wall 100, and inner insulation layer 120, a hexagonal screwdriver is inserted into the hexagonal slot 420, and the circular plate 410 is rotated, causing the lead screw 400 to rotate. The lead screw 400 causes the threaded plate 260 to slide within the slide rail 360. The threaded plate 260 causes the water baffle 250 to slide, and the water baffle 250 causes the lower inclined plate 200 to slide, so that the width between the lower inclined plate 200 and the upper inclined plate 300 is equal to the overall width of the wall 100, outer insulation layer 110, and inner insulation layer 120. Then, the lower inclined plate 200 and the upper inclined plate 300 are fixed to the wall 100, outer insulation layer 110, and inner insulation layer 120. When sealant 600 is used to fill the gap between the lower inclined plate 200 and the upper inclined plate 300, rainwater is prevented from entering. When it rains, the rainwater flows down the slope of the upper inclined plate 300 to the slope of the lower inclined plate 200, and then down the lower inclined plate 200 to drip into the drip groove 240. The rainwater on the back of the upper inclined plate 300 flows down the arc plate 340 to the inner insulation layer 120. The rainwater is blocked by the protruding post 341 inserted into the fixing groove 121, preventing rainwater from seeping into the gap between the upper inclined plate 300 and the inner insulation layer 120. This prevents rainwater from seeping into the gap between the outer insulation layer 110, the inner insulation layer 120 and the wall 100 and causing damage to the wall.

The joints are sealed with glass glue to prevent rainwater from entering the gaps at the joints.
[0043] Working principle: After the first set of lower inclined plates 200 and upper inclined plates 300 are installed, the width of the same lower inclined plates 200 and upper inclined plates 300 is adjusted. The sliding column 221 on the second lower connecting plate 220 at one end of the lower inclined plate 200 and the upper sliding column 321 on the second upper connecting plate 320 at one end of the upper inclined plate 300 are respectively aligned with the sliding groove 211 on the first lower connecting plate 210 at one end of the previous lower inclined plate 200 and the upper sliding groove 311 on the first upper connecting plate 310 at one end of the upper inclined plate 300 and inserted. The two sets of lower inclined plates 200 and upper inclined plates 300 are connected end to end, so that all the walls 100, the outer insulation layer 110 and the inner insulation layer 120 are covered according to the overall length of the roof wall 100. Glass glue is applied at the joints to prevent rainwater penetration. Even if rainwater penetrates, it can be discharged from the joints through the upper intercepting ditch 312 and the lower intercepting ditch 212.
