Description

Technical Field

[0001] This utility model relates to the field of waterproof adhesive strip technology, and in particular to a waterproof adhesive strip for expansion joints in rail transit. Background Technology

[0002] Currently, the expansion joints commonly used in high-speed railway bridges, subway bridges, and other rail transit bridges in China consist of steel components and waterproof rubber strips. Water-retaining platforms are poured on the beam ends on both sides of the expansion joint, and steel components are anchored and embedded in the water-retaining platforms on both sides. The waterproof rubber strips are fixed to the steel components on both sides laterally, and the upper end of the expansion joint is sealed by the waterproof rubber strips to achieve a better waterproof effect. The existing expansion joint waterproof rubber strips of rail transit bridges are installed relatively fixedly, which makes it very difficult, costly, and time-consuming to replace them later.

[0003] In the prior art, patent (CN222160923U) proposes a waterproof strip for expansion joints in rail transit. This prior art waterproof strip seals the upper end of the expansion joint, achieving better waterproofing. The waterproof strip is adjustable for expansion and contraction. Due to temperature changes causing the expansion and contraction of bridge beams, there are gaps between the beam ends. The waterproof strip seals these gaps for waterproofing. To meet the needs of expansion joints, the waterproof strip is typically designed with a V-shape or similar structure. Furthermore, the waterproof strip possesses good toughness, high temperature resistance, and corrosion resistance, increasing its service life and providing better protection for the expansion joint. The expansion joint protection strip is coated with a high-temperature resistant coating and contains polyurethane elastomer. The high-temperature resistant coating and polyurethane elastomer provide better protection for the expansion joint protection strip, increasing its service life. Additionally, the expansion joint protection strip is easy to install and remove.

[0004] However, in the aforementioned existing technologies, the protective rubber strips need to be sealed during installation and disassembly, and the installation requires high precision, which is not conducive to quick disassembly and installation. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof sealing strip for expansion joints in rail transit, which solves the problem that the existing protective sealing strips require sealing during installation and disassembly, have high installation precision, and are not conducive to quick disassembly and installation.

[0006] To achieve the above objectives, this utility model provides a waterproof strip for expansion joints in rail transit, comprising a protective mechanism and two installation mechanisms. Each installation mechanism includes a clamping plate, a clamping frame, an insert frame, a steel component, a positioning component, and a connecting component. One side of the connecting component is fixedly connected to the protective mechanism and located on one side of the protective mechanism.

The clamping plate is detachably connected to the clamping frame and located on the inner side of the clamping frame. The insert frame is fixedly connected to the steel component and located on one side of the steel component.

[0007] The steel profile assembly includes a steel profile body and an inner seat. The inner seat is fixedly connected to the steel profile body and is located on the inner wall of the steel profile body. The steel profile body is fixedly connected to the corresponding clamping plate and is located on one side of the corresponding clamping plate.

[0008] The positioning component includes two grating plates and a positioning rod. The positioning rod is fixedly connected to one of the grating plates and is located inside the grating plate. One of the grating plates is fixedly connected to the steel body and is located at one end of the steel body. The other grating plate is detachably connected to the steel body and is located at the other end of the steel body.

[0009] The connecting assembly includes a plug-in rubber tube and a connecting plate. One side of the connecting plate is fixedly connected to the protective mechanism and is located on one side of the protective mechanism. The other side of the connecting plate is fixedly connected to the plug-in rubber tube and is located on one side of the plug-in rubber tube. The plug-in rubber tube is rotatably connected to the positioning rod and is located around the positioning rod.

[0010] The protective mechanism includes a telescopic protective strip and two coating films. The two coating films are fixedly connected to the telescopic protective strip and are located on the upper and lower sides of the telescopic protective strip, respectively. The two ends of the telescopic protective strip are fixedly connected to the corresponding connecting plates and are located on one side of the corresponding connecting plates, respectively.

[0011] This utility model discloses a waterproof sealing strip for expansion joints in rail transit. The positioning rod within the positioning assembly provides an installation reference for the insertable rubber sleeve within the connecting assembly. Workers can quickly disassemble the grid plate by removing the connection between the frame and the plate. Similarly, the installation and disassembly of the insertable rubber sleeve are also accelerated. The built-in seat within the steel assembly, with its two arc-shaped surfaces, expands the deflection angle of the expansion joint sealing strip, better adapting to actual usage needs. This design is simple in structure, easy to manufacture, and solves the problem that ensuring sealing during installation and disassembly of the sealing strip requires high precision and is not conducive to rapid installation and disassembly.

[0021] In this specific embodiment, one side of the connecting component 108 is fixedly connected to the protective mechanism 101, and the other side of the connecting component 108 is rotatably connected to the positioning component 107.

One side of the connecting plate 114 is fixedly connected to the protective mechanism 101, and the other side of the connecting plate 114 is connected to the insertion rubber sleeve 113. The plug-in rubber tube 113 is rotatably connected to the positioning rod 112. Both coating films 116 are fixedly connected to the telescopic protective rubber strip 115. The two ends of the telescopic protective rubber strip 115 are respectively fixedly connected to the corresponding connecting plate 114. The positioning rod 112 in the positioning assembly 107 provides an installation reference for the plug-in rubber tube 113 in the connecting assembly 108. The operator disassembles the connection between the card frame 104 and the card plate 103 to quickly disassemble the grid plate 111. Similarly, the installation and disassembly of the plug-in rubber tube 113 are also accelerated. The built-in seat 110 in the steel component 106 expands the deflection angle of the telescopic protective rubber strip 115 through the setting of two arc surfaces, better adapting to actual use needs. This design is simple in structure, easy to produce, and solves the problem that the protective rubber strip needs to ensure sealing during installation and disassembly, requires high installation precision, and is not conducive to quick disassembly and installation.

The built-in seat 110 has two arc-shaped surfaces, which can support the connecting plate 114 to deflect at a certain angle without affecting the connection of the connecting plate 114 around the plug-in rubber tube 113, thereby expanding the deflection range of the telescopic protective rubber strip 115, better adapting to actual use needs, and improving durability.

[0024] Meanwhile, one side of the connecting plate 114 is located on one side of the protective mechanism 101, and the other side of the connecting plate 114 is located on one side of the insert rubber tube 113. The insert rubber tube 113 is located around the positioning rod 112. The two coating films 116 are respectively located on the upper and lower sides of the telescopic protective rubber strip 115. The two ends of the telescopic protective rubber strip 115 are respectively located on one side of the corresponding connecting plate 114. The telescopic protective rubber strip 115 has good toughness, high temperature resistance, and corrosion resistance, which can increase its service life and better protect the expansion joint. The coating film 116 is sprayed with a high temperature resistant coating, and the telescopic protective rubber strip 115 is internally provided with polyurethane elastomer. When disassembling the telescopic protective rubber strip 115... When installing the protective strip 115, first remove the grating plate 111 with the clip frame 104, remove the clip frame 104 from the clip plate 103, expose the positioning rod 112 and the insertion tube 113, and then directly pull out the insertion tube 113.

[0025] In this embodiment, the built-in seat 110 has two arc-shaped surfaces. Without affecting the connection of the connecting plate 114 around the plug-in rubber sleeve 113, it can support the connecting plate 114 to deflect at a certain angle, expanding the deflection range of the telescopic protective rubber strip 115, better adapting to actual usage needs, and improving durability. The telescopic protective rubber strip 115 has good toughness, high temperature resistance, and corrosion resistance, which increases its service life and provides better protection for expansion joints. The coating film 116 is sprayed with a high-temperature resistant coating, and the telescopic protective rubber strip 115 has a polyurethane elastomer inside.
