[0029] Please refer to Figure 1 The utility model embodiment provides a kind of plugging structure, it includes: plugging main body 1 and expansion water stop ring 2;Wherein, plugging main body 1 includes opposite first end face and second end face, plugging main body 1 is equipped with flow guide groove 3 on outer peripheral surface, flow guide groove 3 extends from first end face to second end face, plugging main body 1 is used to insert hole;Expansion water stop ring 2 is fixedly covered in the outer peripheral surface of plugging main body 1, and it extends on the part of the path of flow guide groove 3 along the one week of plugging main body 1, expansion water stop ring 2 is used to contact expansion with water in flow guide groove 3, and is closely combined with the inner wall of hole.
[0030] Specific implementation time: when plugging main body 1 is inserted into wall hole, water from outside flows to the area where expansion water stop ring 2 is located along flow guide groove 3, triggers expansion water stop ring 2 to swell when water, and the water stop ring after swelling is closely combined with the inner wall of hole to form sealing interface.Meanwhile, the extension path of flow guide groove 3 directs water to expansion water stop ring 2, avoids the disorder diffusion of water in hole.Such setting, by flow guide groove 3, water is actively guided to the specific area of expansion water stop ring 2, ensures that water triggers expansion sealing mechanism quickly, solves the sealing failure problem caused by the gap between traditional plugging structure and hole due to water seepage;The full week coverage design of expansion water stop ring 2 further strengthens sealing uniformity, effectively blocks water seepage path.In addition, the synergistic effect of flow guide groove 3 and expansion water stop ring 2 reduces the dependence of plugging structure on construction precision, simplifies installation process, significantly improves wall waterproof effect and structural stability.
[0031] As a possible implementation, an annular groove is further formed along the outer circumferential surface of the plugging body 1 at the end of the diversion groove 3 away from the first end surface, the annular groove intersects with the diversion groove 3, and the expansion waterstop ring 2 is embedded and fixed in the annular groove and in contact with the groove bottom of the diversion groove 3.
[0032] An annular groove is formed along the outer circumferential surface of the plugging body 1 at the end of the diversion groove 3 away from the first end surface, and the annular groove intersects with the diversion groove 3, and the expansion waterstop ring 2 is embedded and fixed in the annular groove. The structural feature of this design is that the intersection of the annular groove and the diversion groove 3 allows water in the diversion groove 3 to directly permeate onto the annular surface of the expansion waterstop ring 2. In specific implementation, water flows into and permeates the expansion waterstop ring 2 through the diversion groove 3, prompting the expansion waterstop ring 2 to absorb water and expand, thereby forming an effective sealing effect. Through the structural design of the intersection of the annular groove and the diversion groove 3, water can directly permeate onto the expansion waterstop ring 2, causing it to quickly absorb water and expand and achieve high-efficiency sealing, avoiding the problem of sealing failure due to insufficient contact of water with the expansion waterstop ring 2.
[0033] In addition, the depth of the annular groove can be designed to be greater than the depth of the diversion groove 3, which not only ensures that water can smoothly permeate into the expansion waterstop ring 2, but also further enhances the connection stability of the expansion waterstop ring 2. Deepening the depth of the annular groove further enhances the connection stability of the expansion waterstop ring 2, preventing it from shifting or loosening during expansion. This design is simple and easy to implement, while taking into account both sealing performance and connection reliability, reducing maintenance costs and improving overall service life.
[0034] As a possible implementation, the diversion groove 3 extends helically along the axis of the plugging body 1.
[0035] In this way, the helical diversion groove 3 can lengthen the flow path of water and increase its contact area with the surface of the plugging body 1, thereby ensuring that water more fully permeates onto the expansion waterstop ring 2 and prompting it to quickly absorb water and expand. The helical design makes water flow more uniform and stable, avoiding the problem of possible local water accumulation or flow blockage, while effectively preventing water from diffusing into the wall structure due to water accumulation or poor flow, improving the overall waterproof performance of the structure.
[0036] In some embodiments, the diversion groove 3 is linear. The linear diversion groove 3 is simple in structure and easy to manufacture, which can reduce production costs.
[0037] As a possible implementation, the plugging structure further includes a waterproof rubber plug, which is fixed and attached to the first end surface.
[0038] The waterproof rubber plug is tightly attached to the first end face to form a reliable waterproof layer, thereby enhancing the overall waterproof performance of the sealing structure and preventing external moisture from penetrating into the internal structure to cause damage.
[0039] As a possible implementation, the material of the expansion waterstop ring 2 is water-swelling rubber material or polyurethane-based water-absorbing expansion material. When the material of the expansion waterstop ring 2 is water-swelling rubber material or polyurethane-based water-absorbing material, the expansion waterstop ring 2 can actively fill the gap after swelling after absorbing water to form a reliable sealing barrier. The water-swelling rubber has both elasticity and adaptability, can cope with structural deformation and complex surfaces, and is convenient to construct and has low cost; the polyurethane-based material realizes high strength and controllable expansion through interpenetrating network structure, and has excellent chemical medium resistance.
[0040] In some embodiments, the groove wall and the groove bottom of the flow guide groove 3 are formed with rough structures. The groove wall and the groove bottom of the flow guide groove 3 are designed to be rough surfaces, which can be uneven lines or fine particles. When water flows through the flow guide groove 3, the rough surface will disrupt the original smooth flow state of the water, generating eddy current or friction resistance. This design can increase the contact area between water and the flow guide groove 3, slow down the flow rate through surface friction, and help water flow along the flow guide route of the flow guide groove 3, preventing water from spreading to the surrounding wall.
[0041] As a possible implementation, the sealing structure further includes a limiting ring 4, which is integrally formed with the sealing body 1, and the limiting ring 4 is arranged along the circumference of the sealing body 1 and in contact with the expansion waterstop ring 2.
[0042] Specifically, the limiting ring 4 is directly cast or injection molded on the outer surface of the sealing body 1 in the form of an annular protrusion, and is arranged around the outer edge of the expansion waterstop ring 2. The inner wall thereof is attached to the outer side of the waterstop ring to ensure that the limiting ring 4 only restricts the lateral expansion of the waterstop ring during the expansion, without hindering the longitudinal expansion. In this way, when the expansion waterstop ring 2 swells after encountering water, the rigid structure of the limiting ring 4 transmits the pressure to the sealing body 1, avoiding local damage to the waterstop ring, and under the possible influence of vibration, the displacement trend of the expansion waterstop ring 2 is offset through the frictional contact between the limiting ring 4 and the expansion waterstop ring 2, ensuring the positional certainty of the expansion waterstop ring 2. This simplifies the installation process, eliminates the need for additional fixing parts, improves the sealing stability through physical constraints, and further improves the waterproof sealing effect.
[0043] In some embodiments, the limiting ring 4 can be composed of a plurality of independent arc-shaped blocks fixed on the sealing body 1.
[0044] The building wall provided by the embodiments of the present application comprises a wall and the sealing structure described above; the wall is provided with a hole penetrating the interior of the wall; at least part of the sealing structure is located in the hole, and the first end surface of the sealing structure is close to the surface of the wall.
[0045] In the implementation, the second end surface of the sealing structure is inserted into the hole of the wall, and the first end surface of the sealing structure is close to the surface of the wall. The building wall provided by the embodiments of the present application has the same beneficial effects as the sealing structure described above, and details are not repeated here.
[0046] As a possible implementation, the building wall further comprises a waterproof layer covering the first end surface of the sealing structure and the surface of the wall. The waterproof layer seamlessly connects the sealing structure and the surface of the wall, eliminates the water seepage weak point between them, forms a continuous waterproof barrier, and at the same time, the design of the waterproof layer cooperates with the waterproof mechanism of the expansion waterstop ring 2 to form a double protection of rigid sealing and flexible covering, further improving the waterproof sealing effect.
[0047] An embodiment of the sealing structure is listed below and the working principle of the embodiment is described: after the sealing main body is inserted into the hole on the wall, the gap is sealed by using micro-expansion waterstop mortar, and the sealing is completed. When there is external water seepage, the water seeped from the outside is directed to the annular groove area through the spiral flow guide groove or the straight line type flow guide groove on the outer wall of the sealing main body, and the rough structure of the groove wall and the groove bottom slows down the flow rate of the water through surface friction, further strengthening the directional guiding effect of the water; the water flowing to the annular groove area is immersed into the expansion waterstop ring embedded in the annular groove, the expansion waterstop ring absorbs water and expands, and is constrained by the limiting ring integrally formed in the circumferential direction of the sealing main body, expands uniformly along the inner wall of the hole to form a continuous sealing bag, and tightly fits the inner wall of the hole, thereby enhancing the sealing effect. At the same time, the waterproof rubber plug covering the first end surface of the sealing main body fills the micro gap with the surface of the wall through flexible deformation, and blocks the external penetration path. In this way, the flow guide groove actively concentrates the water seepage to trigger the expansion of the expansion waterstop ring, the limiting ring inhibits the lateral deviation of the material and transmits the pressure, and the waterproof rubber plug forms a terminal protection seal, thereby significantly improving the reliability and structural stability of the wall waterproof sealing.
[0048] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
[0049] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
