Description

TECHNICAL FIELD

[0001] The utility model relates to waterstop technology field, concretely is a waterstop. BACKGROUND

[0002] In many fields such as building, water conservancy, traffic, waterproof engineering has been a crucial link, and waterstop as the key component in waterproof system, its performance advantage and disadvantage directly influence the waterproof quality of the whole project. With all kinds of engineering projects to the large-scale, complex and the durability requirement increasingly higher direction development, traditional waterstop has gradually exposed many limitations.

[0003] Traditional waterstop structure is relatively simple, usually only rely on single rubber or plastic material to realize waterstop function. When facing the deformation situation of complex engineering structure, such as the settlement joint of large building, bridge expansion joint and the deformation joint of water conservancy dam, due to the lack of effective deformation adaptation mechanism, traditional waterstop often cannot follow the synchronous deformation of structure, and it is easy to cause the gap between waterstop and structure, and further cause leakage problem. For example, the high-rise building basement built on some soft soil foundation, with the settlement of building main body, traditional waterstop cannot flexibly stretch or bend, so that underground water can easily penetrate the joint between waterstop and basement wall, which seriously affects the normal use of basement, and may cause equipment damage, decoration material mildew and other consequences.

[0004] In addition, from the construction convenience, traditional waterstop often needs complex process and professional technical personnel operation in splicing installation process, and consumes a lot of time and labor cost. The connecting part between different waterstops is often the weak link of waterproof, if the connection is not firm or sealing is not in place, leakage hidden danger is easy to appear at this place, which affects the integrity of the whole waterproof engineering.

[0005] In addition, from the construction convenience, traditional waterstop often needs complex process and professional technical personnel operation in splicing installation process, and consumes a lot of time and labor cost. The connecting part between different waterstops is often the weak link of waterproof, if the connection is not firm or sealing is not in place, leakage hidden danger is easy to appear at this place, which affects the integrity of the whole waterproof engineering.

[0006] In summary, in view of the many problems of traditional waterstop in deformation adaptation ability, strength durability and construction convenience in prior art, it is urgent to develop a new structure waterstop to meet the high standard requirement of modern engineering construction to waterproof quality. The present application is based on this background and proposes an innovative waterstop design. UTILITY MODEL CONTENT

[0007] The utility model provides a waterstop.

[0008] The utility model employs the technical scheme: a waterstop, including waterstop main part, the middle part of waterstop main part is provided with the bulge hollow cylinder of deformation, the upper and lower surfaces of waterstop main part on both sides of hollow cylinder of deformation are provided with a plurality of reinforcing ribs, is equipped with the through -hole on the reinforcing rib, and the upper and lower surfaces of waterstop main part between reinforcing rib and reinforcing rib are provided with a plurality of hollow bulges, the hollow bulge is filled with gas or liquid, the both ends of waterstop main part are provided with the quick -witted mechanism for the splicing of a plurality of waterstop main part.

[0009] Further, the reinforcing rib cross section is trapezoidal structure.

[0010] Further, the hollow bulge is hemispherical structure or is half elliptical structure.

[0011] Further, the waterstop main part includes the middle elastic rubber layer, the polyester fiber reinforced layer of composite setting in the elastic rubber layer upside and down and the rubber coating of setting on the polyester fiber reinforced layer.

[0012] Further, the thickness of the elastic rubber layer is 45%-60% of the total thickness of the waterstop main part, the thickness of the polyester fiber reinforced layer is 30%-40% of the total thickness of the waterstop main part, and the thickness of the rubber coating is 15%-20% of the total thickness of the waterstop main part.

[0013] Further, the quick -witted mechanism includes the connecting male end on one end of waterstop main part and the connecting female end on the other end, two butt joint grooves are arranged on the connecting female end, a plurality of arc concaves are arranged in the butt joint groove at intervals, two butt joint plates embedded in the butt joint groove are arranged on the connecting male end, and the upper and lower surfaces of the butt joint plate have arc protrusions embedded with the arc concaves.

[0014] Further, the back of the butt joint groove is provided with a fixing hole, and the butt joint plate is provided with a fixing screw hole corresponding to the fixing hole.

[0015] The utility model has the advantages of:

[0016] First, the bulge hollow cylinder of deformation arranged in the middle of the waterstop main part provides excellent deformation adaptability. The hollow cylinder structure as a buffer unit can be compressed or stretched freely according to the displacement change of the structure when the waterstop is applied to the deformation engineering part such as settlement, expansion, etc., such as the settlement joint of large buildings. Compared with the traditional waterstop, it can still maintain good sealing state under larger deformation conditions, effectively preventing underground water, rainwater and other liquids from seeping into the deformation joint.

[0017] Secondly, the several reinforcing ribs distributed on the upper and lower surfaces of the main body of the waterstop on both sides of the deformed hollow cylinder play a key reinforcing role. The through holes provided on the reinforcing ribs, on the one hand, reduce the weight of the reinforcing ribs, avoiding adding too much additional load to the whole waterstop; on the other hand, the existence of the through holes enables the reinforcing ribs to better deform in cooperation with the surrounding rubber material when stressed, thereby enhancing the flexibility of the whole structure. Meanwhile, the hollow protrusions between the reinforcing ribs are filled with gas or liquid, further optimizing the performance of the waterstop. When the waterstop is impacted by external force, such as high water pressure in water conservancy projects, the hollow protrusions can serve as a buffer area, and the gas or liquid filled in the hollow protrusions can be moderately compressed or expanded according to the pressure change, thereby uniformly dispersing the external force and effectively protecting the main body of the waterstop from being torn or damaged. The unique structural design enables the waterstop to have stronger impact resistance, and compared with the traditional waterstop, the waterstop can maintain longer water-stopping effect in a harsh stress environment.

[0018] Furthermore, the quick connection mechanism provided at both ends of the main body of the waterstop significantly improves the construction convenience. In the construction, water conservancy and other engineering sites, the construction progress is often crucial. The traditional waterstop needs to consume a lot of time for fine bonding or welding operation when splicing, and also requires the operator to have excellent professional skills. The quick connection mechanism of the present application simplifies the splicing process, and ordinary construction personnel can quickly and accurately connect multiple waterstop bodies together according to simple operation steps, which not only saves a lot of manpower and time cost, but also greatly reduces the risk of leakage caused by improper connection. The sealing property and stability of the connection part are reliably guaranteed by the quick connection mechanism, so that the construction efficiency and quality of the whole waterproof engineering are greatly improved.

[0019] In addition to the purposes, features and advantages described above, the present application has other purposes, features and advantages. The present application will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0027] The utility model provides a kind of waterstop.

[0028] In the present embodiment, with reference to Figures 1-4 The waterstop includes a waterstop body 1, a raised deformed hollow cylinder 2 is arranged in the middle of the waterstop body 1, a plurality of reinforcing ribs 3 are arranged at intervals on the upper and lower surfaces of the waterstop body on both sides of the deformed hollow cylinder 2, through holes 4 are arranged on the reinforcing ribs 3, a plurality of hollow protrusions 5 are arranged on the upper and lower surfaces of the waterstop body between the reinforcing ribs, the hollow protrusions 5 are filled with gas or liquid, and quick connection mechanisms are arranged at both ends of the waterstop body for splicing a plurality of waterstop bodies.

[0029] In the above technical solution, the raised deformed hollow cylinder in the middle of the waterstop body gives the waterstop excellent ability to adapt to complex deformation conditions. In addition, the plurality of reinforcing ribs arranged at intervals on the upper and lower surfaces of the waterstop body on both sides, in cooperation with the through hole design, not only reduce the weight of the waterstop to avoid excessive increase in the load of the waterstop, but also enhance the overall structural toughness. When subjected to stress, it can deform cooperatively with the surrounding rubber material to provide all-round support and protection for the waterstop, strengthen its ability to resist external damage, and ensure the waterstop performance in high-pressure and high-impact environments.

[0030] The hollow protrusions between the reinforcing ribs are filled with gas or liquid (such as nitrogen or silicone oil), which forms a high-efficiency buffer system. When subjected to external forces such as high water pressure in water conservancy projects or impact in construction, the hollow protrusions will adaptively compress or expand according to the pressure change, uniformly disperse the impact force, prevent the main body of the waterstop from tearing and breaking, prolong the service life, and maintain stable water-stopping effect under harsh working conditions.

[0031] The quick connection mechanism at both ends of the waterstop main body brings convenience to the splicing of multiple waterstops. By abandoning traditional complex bonding and welding operations, ordinary construction personnel can quickly and accurately connect multiple waterstop main bodies in simple steps, greatly shortening the construction time and reducing labor costs, and ensuring the sealing and stability of the splicing part through reliable connection, eliminating leakage risks, and improving the overall quality and efficiency of waterproof engineering.

[0032] Specifically, the reinforcing rib cross section is a trapezoidal structure.

[0033] In this embodiment, the reinforcing rib cross section is a trapezoidal structure, which has unique mechanical advantages compared to common rectangular cross sections. When subjected to external forces, the inclined edge of the trapezoidal structure can guide the stress to be more evenly distributed in the waterstop main body, avoiding stress concentration and local damage. Especially when the waterstop is subjected to transverse tension or pressure, the trapezoidal reinforcing rib can provide more stable support and enhance the overall anti-deformation ability of the waterstop, further ensuring the water-stopping effect in complex stress environments.

[0034] Specifically, the hollow protrusion is a hemispherical structure or a semi-elliptical structure.

[0035] In this embodiment, the hollow protrusion is a hemispherical structure or a semi-elliptical structure. This arc-shaped design makes the hollow protrusion have better buffering characteristics when subjected to stress. Compared to angular shapes, the arc shape can more smoothly guide the dispersion of external forces and reduce stress concentration points.

[0036] Specifically, the waterstop main body includes an intermediate elastic rubber layer 6, a polyester fiber reinforced layer 7 arranged on the elastic rubber layer 6, and a rubber coating layer 8 arranged on the polyester fiber reinforced layer.

[0037] In the embodiment, the waterstop body adopts a multi-layer structure design of an intermediate elastic rubber layer, a composite arrangement of polyester fiber reinforced layers above and below the elastic rubber layer, and a rubber coating layer arranged on the polyester fiber reinforced layer, realizing the complementary advantages of multiple materials. The elastic rubber layer serves as the main waterstop barrier, the inner layer is a high-strength rubber layer, has good elasticity and water resistance, and as the main waterstop barrier, can produce moderate deformation to seal the gap when subjected to water pressure; the polyester fiber reinforced layer injects high-strength characteristics into the overall structure, greatly improves the tensile and tear resistance of the waterstop, and enables it to withstand greater external forces; the rubber coating layer has excellent weather resistance, wear resistance and adhesion, and the coating layer can be tightly bonded with the surface of structures such as concrete and metal, preventing displacement or water channeling of the waterstop during use. Ensure that the waterstop is tightly attached to the surrounding structure under different working conditions, and comprehensively improve the durability, anti-deformation ability and waterproof effect of the waterstop.

[0038] Specifically, the thickness of the elastic rubber layer is 45%-60% of the total thickness of the waterstop body, the thickness of the polyester fiber reinforced layer is 30%-40% of the total thickness of the waterstop body, and the thickness of the rubber coating layer is 15%-20% of the total thickness of the waterstop body.

[0039] In the embodiment, the thickness proportions of the elastic rubber layer, the polyester fiber reinforced layer and the rubber coating layer are reasonably adjusted, i.e. the thickness of the elastic rubber layer is 45%-60% of the total thickness of the waterstop body, ensuring sufficient elastic sealing material for the waterstop core function and ensuring good waterstop effect; the thickness of the polyester fiber reinforced layer is 30%-40% of the total thickness of the waterstop body, providing just the right amount of high-strength support without increasing the weight, and strengthening the waterstop's ability to resist external force damage; the thickness of the rubber coating layer is 15%-20% of the total thickness of the waterstop body, which can effectively protect the inner structure from external erosion and ensure the adhesion performance with the external structure. Through precise thickness ratio design, the waterstop achieves an optimal balance in all aspects of performance, meeting the needs of a wide range of engineering applications.

[0040] In addition, it should be noted that the total thickness of the waterstop body specifically refers to the height h in the formula. Figure 1

[0041] Specifically, the quick connection mechanism includes a connecting male end 9 on one end of the waterstop body and a connecting female end 10 on the other end, the connecting female end 10 is provided with two butt grooves 11, a plurality of arc-shaped concave surfaces 12 are arranged in the butt grooves 11 at intervals, the connecting male end is provided with two butt plates 13 embedded in the butt grooves, and the upper and lower surfaces of the butt plates 13 have arc-shaped protrusions 14 that are embedded with the arc-shaped concave surfaces.

[0042] ​In the embodiment, the female end of the quick connecting mechanism is provided with two butt grooves, a plurality of arc concaves are arranged in the butt grooves at intervals, and the male end is correspondingly provided with two butt plates embedded in the butt grooves and arc protrusions on the upper and lower surfaces, thereby forming a reasonable and effective mechanical connecting structure. The mutual embedding of the arc concaves and the arc protrusions not only realizes quick positioning and facilitates the construction personnel to quickly find the connecting position on site, but also provides strong transverse constraint after connection, prevents the waterstop from being transversely displaced during use, ensures the sealing of the splicing part, and improves the waterproof reliability.

[0043] Specifically, the back surface of the butt groove is provided with a fixing hole 15, and the butt plate is provided with a fixing screw hole 16 corresponding to the fixing hole.

[0044] In the embodiment, the back surface of the butt groove is provided with a fixing hole, and the butt plate is provided with a fixing screw hole corresponding to the fixing hole, thereby further strengthening the connection stability of the quick connecting mechanism. After the embedding of the arc concaves and the arc protrusions is completed, the bolt is tightened through the fixing hole and the fixing screw hole, thereby providing additional longitudinal fastening force for the splicing part of the waterstop, effectively resisting external forces such as longitudinal tension and pressure, eliminating the leakage problem caused by loose connection, and comprehensively ensuring the sealing and stability of the splicing part, thereby building a solid foundation for the entire waterproof engineering.
