Description
Technical Field
[0001] The utility model relates to the technical field of anti-water seepage of building exterior walls, in particular to an anti-water seepage structure of building exterior walls. Background Art
[0002] In house construction, exterior walls built with masonry are prone to water seepage, especially exterior walls located in basements. Since the walls are lower than the ground, external rainwater can easily penetrate into the walls, causing the walls to mold. A Chinese patent search has disclosed a water-seepage-proof building exterior wall structure, with its authorization announcement number CN217557291U. The utility model is designed with a collection pool, a drainage pipe and an underground drainage pipe to discharge water entering the exterior wall, ensuring that rainwater does not pass through the brick layer into the inner wall surface. However, when there is too much groundwater, it will penetrate into the collection pool through the underground drainage pipe and the drainage pipe, resulting in excessive moisture in the brick layer. The moisture vapor is easily allowed to enter the inner wall surface, thereby affecting the effect of the building exterior wall water-seepage-proof structure. Utility Model Content
[0003] The purpose of the utility model is to provide an anti-seepage structure for building exterior walls to solve the problem raised in the above-mentioned background technology that when there is too much groundwater, it will penetrate into the collection pool through underground drainage pipes and drainage pipes, resulting in excessive moisture in the brick layer, which makes it easy for moisture to enter the inner wall surface, thereby affecting the effect of the anti-seepage structure of the building exterior wall.
[0004] To achieve the above object, the utility model provides the following technical solution: a building exterior wall water seepage prevention structure, the building exterior wall water seepage prevention structure comprising:
[0005] A base body, wherein a receiving frame, a blocking plate and a guide plate are arranged inside the base body, wherein the blocking plate is connected to a fixing plate and a sealing gasket, wherein four corners of one end of the receiving frame are provided with a return spring, wherein the base body is connected to a drain pipe, wherein a grille is arranged inside the drain pipe;
[0006] The brick layer body is connected to the base body, and a drainage plate is arranged inside the brick layer body.
[0007] Preferably, a drainage groove is provided on the middle side wall of the upper end of the base body, and a discharge groove is provided on one side of the drainage groove of the base body. The inner wall of the drainage groove away from the opening is fixedly connected to the guide plate, and the upper side wall of the guide plate has a certain slope.
[0008] Preferably, a slope plate is fixedly connected to the inner wall on one side of the bottom end of the drainage trough, the inner wall on one side of the drainage trough is fixedly connected to one end of the drainage pipe, and the inner wall on the other end of the drainage pipe is fixedly connected to the grille.
[0009] Preferably, the two ends of the fixed plate are fixedly connected to the inner walls of the drainage groove on both sides above the excretion groove, the middle side wall of the fixed plate close to one end of the ramp plate is fixedly connected to the blocking plate, and the outer wall of the other end of the blocking plate is fixedly connected to the sealing gasket.
[0010] Preferably, the four corner side walls of one end of the receiving frame are provided with installation grooves, the inner wall of the installation groove at one end away from the opening is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the inner wall of the excretion groove near the drainage groove.
[0011] Preferably, the receiving frame is funnel-shaped, and a groove matching with one end of the guide plate is formed on one side of the receiving frame.
[0012] Preferably, a drainage hole cooperating with the blocking plate is provided in the middle of a side wall of one end of the receiving frame close to the slope plate.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] When there is no water flowing into the receiving frame from the guide plate, the elastic force of the reset spring makes the upper side wall of the receiving frame fit with the inner wall of the drainage groove, and the sealing plate and the sealing gasket seal the drainage hole, blocking the moisture vapor of groundwater from entering the interior of the brick layer body, preventing the moisture vapor in the brick layer body from excessively penetrating into the inner wall surface, and ensuring the anti-seepage structural effect of the building exterior wall;
[0015] When rainwater penetrates into the brick layer, the rainwater falls onto the guide plate through the discharge plate under the action of gravity. Since the guide plate is inclined, the water on the guide plate quickly flows into the receiving frame. Since the receiving frame is funnel-shaped, the water that slides off the guide plate is concentrated and flows into the receiving frame. When the receiving frame collects a certain weight of rainwater, the return spring is stretched by the self-gravity of the rainwater, so that the receiving frame moves downward, thereby separating the blocking plate and the sealing gasket from the drainage hole. At this time, the water flow in the receiving frame is quickly discharged into the drainage trough through the drainage hole, and is quickly discharged into the drainage pipe through the slope plate, so that the drainage pipe discharges the internal water flow into the ground, avoiding water accumulation in the drainage trough, thereby preventing further penetration of rainwater.
