Description

Technical Field

[0001] This invention belongs to the field of waterstop construction technology, specifically relating to a device for effectively fixing waterstops in expansion joints. Background Technology

[0002] With the rapid development of my country's railway construction industry, the standardization requirements for tunnel construction are gradually increasing, and higher requirements are also placed on the tunnel's waterproofing and drainage construction technology. Tunnels are underground pipelines formed by multiple reinforced concrete structures poured in stages. Structural deformation joints are inevitably left between the segments. To prevent water leakage at these deformation joints, a common design and construction method is to install embedded waterstops within the cast-in-place concrete structure at the expansion joints. This serves to prevent water leakage at the deformation joints and during uneven settlement.

[0003] Chinese Invention Patent Publication No. CN102943530B discloses a construction method for a fixed device for an embedded ultra-thin steel-edged rubber waterstop. The device includes a positioning rod, a flange rod, and locking reinforcing bars. A sealing rod is provided at the lower end of the positioning rod. Two positioning rods of equal length and parallel to each other are included. Two flange rods of equal length with their center lines coinciding are also included. Two locking reinforcing bars are located inside the positioning rod. The positioning rod is perpendicular to the sealing rod and flange rod, and the two positioning rods and flange rod are symmetrically arranged along the center of the sealing rod. This invention accurately constrains and fixes the embedded steel-edged rubber waterstop during concrete pouring without damaging it, ensuring accurate positioning of the waterstop in the concrete and guaranteeing its water-stopping effect.

[0004] Chinese Invention Patent Publication No. CN110397081B discloses a method for fixing an embedded rubber waterstop and a reinforcing steel frame structure. The method includes an outer frame, an inner frame fixedly connected to the outer frame via connecting pipes, and a supporting frame fitted over the inner frame, with the supporting frame and inner frame fixedly connected via connecting pipes. This method for fixing an embedded rubber waterstop and the reinforcing steel frame structure, through improvements to the fixing method, can reliably fix the waterstop at the expansion joint of a pipe gallery. This ensures that the waterstop's installation position and tilt meet design requirements, effectively controlling water seepage at the expansion joint, thus fully utilizing the waterstop's water-stopping and barrier functions and extending the service life of the pipe gallery.

[0005] Chinese Invention Patent Publication No. CN113818493B discloses a method for installing and fixing an embedded rubber waterstop. The method includes: installing longitudinal structural bars, transverse structural bars, and reinforcing bars; bending the steel structure into a four-shaped frame structure, using two horizontal sides to sequentially complete a first wrapping part and a second wrapping part at the opening, and installing a stop strip on the first side; fixing the bottom of a U-shaped positioning hoop to the installed lower longitudinal and transverse structural bars; installing the embedded rubber waterstop onto the U-shaped positioning hoop, clamping the strip ribs of the embedded rubber waterstop between the two horizontal sides using the first and second wrapping parts; and fixing the top of the U-shaped positioning hoop with the embedded rubber waterstop installed to the installed upper structural bars. This invention achieves the effect of preventing the embedded rubber waterstop from deviating or being squeezed out of the formwork during the cast-in-place concrete operation.

[0006] Based on the above patent analysis, after the waterstop is fixed, the angle between one end of the waterstop and the middle hollow ring cannot be adjusted during the concrete pouring process, so that the air at the lower edge of the waterstop is not easy to escape during the concrete pouring process. Summary of the Invention

[0007] The purpose of this invention is to provide an effective device for fixing expansion joint waterstops, which aims to solve the problem that after the waterstop is fixed, the angle between one end of the waterstop and the middle hollow ring cannot be adjusted during the concrete pouring process, making it difficult for air to escape from the lower edge of the waterstop during the concrete pouring process.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] A device for effectively fixing a waterstop in an expansion joint includes a steel-edged rubber waterstop, which is detachably connected to a template. One end of the steel-edged rubber waterstop, away from the template, is connected to an adjusting component. One end of the adjusting component is connected to a reinforcing cage. The adjusting component includes a connecting rod, a movable sleeve, a threaded rod, and a crossbeam. One end of the connecting rod is connected to the steel-edged rubber waterstop, and the other end of the connecting rod is hinged to the movable sleeve. The movable sleeve is threadedly connected to the threaded rod, which is rotatably connected to the crossbeam. One end of the crossbeam is connected to the reinforcing cage, and the end of the crossbeam away from the reinforcing cage is close to the template. Under external force, the threaded rod rotates to drive the movable sleeve towards the template end, thereby causing the steel-edged rubber waterstop to tilt upwards.

[0010] Furthermore, the crossbeam is fixedly connected to a threaded section, which is located at one end of the threaded rod. A locking nut is provided at the end of the threaded section away from the threaded rod. When the locking nut is in the working position, the threaded section and the threaded rod are tightly connected.

[0011] Furthermore, the locking nut is fixedly connected to a sliding sleeve at the end away from the threaded section, and the sliding sleeve is adapted to the crossbeam.

[0012] Furthermore, a nut is provided at the end of the threaded rod away from the threaded section, and the nut is fixedly connected to the threaded rod.

[0013] Furthermore, a locking bolt is provided between the connecting rod and the movable sleeve. When the locking bolt is in the working position, the connecting rod is fixedly connected to the movable sleeve.

[0014] Furthermore, there are several adjustment components, and each adjustment component is spaced apart along the length direction of the steel-edged rubber waterstop.

[0015] Furthermore, the template includes an upper template and a lower template. The upper template has an annular groove one near the lower template end, and the annular groove one extends from one end of the upper template to the other end. The lower template has an annular groove two near the upper template end, and the annular groove two extends from one end of the lower template to the other end. The hollow ring in the middle of the steel-edged rubber waterstop is located between the annular groove one and the annular groove two.

[0016] Furthermore, the template is provided with a protective component at the end away from the adjustment component, and the protective component is used to connect the steel-edged rubber waterstop to the template at the end away from the protective component.

[0017] Furthermore, the protective component includes an arc-shaped part, a threaded hole, and a connecting bolt. The arc-shaped part is adapted to the steel-edged rubber waterstop. One end of the arc-shaped part is hinged to the upper template, and the other end of the arc-shaped part is provided with a through hole. The lower template is provided with a threaded hole, and the threaded hole corresponds to the through hole. The connecting bolt passes through the through hole and connects to the lower template through the threaded hole.

[0018] A construction method for an effective device for fixing expansion joint waterstops includes the following steps:

[0019] Step 1: Fix the steel-edged rubber waterstop using a template, ensuring that the hollow ring in the middle of the steel-edged rubber waterstop is positioned in the center of the expansion joint.

[0020] Step 2: Connect one end of the steel-edged rubber waterstop to one end of the connecting rod, and hinge the other end of the connecting rod to the movable sleeve. The movable sleeve is threaded to the threaded rod, and the threaded rod is rotatably connected to the crossbeam. One end of the crossbeam is connected to the reinforcing cage, so that the steel-edged rubber waterstop is laid flat. The connecting rod is fixedly connected to the movable sleeve by tightening the bolts.

[0021] Step 3: Use the arc-shaped component to move the steel-edged rubber waterstop away from the connecting rod end and closer to the lower template, and connect the arc-shaped component to the lower template using connecting bolts;

[0022] Step 4: When pouring concrete, loosen the tightening bolts, rotate the threaded rod to move the moving sleeve toward the template end, and the moving sleeve drives the connecting rod to make the steel-edged rubber waterstop tilt upwards near the connecting rod end, so that the tilted end of the steel-edged rubber waterstop and the middle hollow ring of the steel-edged rubber waterstop form a horizontal angle of 15°-30°.

[0023] Step 5: Tighten the threaded section and threaded rod by locking the nut;

[0024] Step 6: When the concrete pouring surface is level with the steel-edged rubber waterstop, loosen the locking nut and reverse the threaded rod to move the movable sleeve away from the template end, and flatten the raised end of the steel-edged rubber waterstop so that the steel-edged rubber waterstop is laid flat. Then, fix the movable sleeve to the connecting rod with the locking bolt and continue pouring concrete.

[0025] Step 7: After the concrete has solidified, unscrew the connecting bolts to open the arc-shaped parts, allowing the steel-edged rubber waterstop to open away from the connecting rod end, and remove the upper and lower formwork.

[0026] Step 8: Connect one end of the open end of the steel-edged rubber waterstop to the connecting rod, and hinge the other end of the connecting rod to the movable sleeve. The movable sleeve is threadedly connected to the threaded rod, and the threaded rod is rotatably connected to the crossbeam. One end of the crossbeam is connected to the reinforcing cage.

[0027] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned structure, are as follows:

[0028] The present invention relates to a steel-edged rubber waterstop that is disassembled and connected to a template. The end of the steel-edged rubber waterstop furthest from the template is connected to an adjusting component, and one end of the adjusting component is connected to a reinforcing cage. The adjusting component includes a connecting rod, a movable sleeve, a threaded rod, and a crossbeam. One end of the connecting rod is connected to the steel-edged rubber waterstop, and the other end of the connecting rod is hinged to the movable sleeve. The movable sleeve is threadedly connected to the threaded rod, which is rotatably connected to the crossbeam. One end of the crossbeam is connected to the reinforcing cage, and the end of the crossbeam furthest from the reinforcing cage is close to the template. Under external force, the threaded rod rotates to drive the movable sleeve towards the template end, thereby causing the steel-edged rubber waterstop to tilt upwards. The present invention, through the cooperation of the connecting rod, movable sleeve, threaded rod, and crossbeam, causes one end of the steel-edged rubber waterstop to tilt upwards, forming an angle between the steel-edged rubber waterstop and its central hollow ring. The size of this angle can be determined by the distance the movable sleeve moves along the threaded rod. The adjustment mechanism allows air bubbles at the lower edge of the steel-edged rubber waterstop to escape along the raised edge of the waterstop during concrete pouring. This solves the problem of not being able to adjust the angle between one end of the waterstop and the central hollow ring during concrete pouring after the waterstop is fixed, thus preventing air from easily escaping from the lower edge of the waterstop. In summary, this invention, through the cooperation of the connecting rod, the movable sleeve, the threaded rod, and the crossbeam, causes one end of the steel-edged rubber waterstop to bend upwards, forming an angle between the steel-edged rubber waterstop and the central hollow ring. The size of the angle can be adjusted by the distance the movable sleeve moves along the threaded rod, allowing air bubbles at the lower edge of the steel-edged rubber waterstop to escape along the raised edge during concrete pouring. This invention is suitable for waterstop installation. Attached Figure Description

Implementation

[0038] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0039] This embodiment discloses a device for effectively fixing the waterstop strip of the expansion joint, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the system includes a steel-edged rubber waterstop 1, a disassembly and connection template 2 for the steel-edged rubber waterstop 1, and the template 2 located at the expansion joint. The template 2 positions the hollow ring of the steel-edged rubber waterstop 1 in the middle of the expansion joint, dividing the steel-edged rubber waterstop 1 into left and right parts. The template 2 is fixed using existing technology. Multiple connection holes are drilled into the steel edge of the steel-edged rubber waterstop 1 using a machine tool. These connection holes are spaced apart along the length of the steel-edged rubber waterstop 1. An adjustment component 3 is connected to the end of the steel-edged rubber waterstop 1 furthest from the template 2. One end of the adjustment component 3 is connected to a reinforcing cage 4. The adjustment component 3 consists of multiple... Multiple adjustment components 3 are spaced apart along the length of the steel-edged rubber waterstop 1. The adjustment component 3 includes a connecting rod 301, a movable sleeve 302, a threaded rod 303, and a crossbeam 304. The connecting rod 301 can also be a length-adjustable connecting rod. The length-adjustable connecting rod includes a threaded sleeve. The two ends of the threaded sleeve are threadedly connected to screws. When the threaded sleeve rotates forward, the screws at both ends extend outward to lengthen the connecting rod 301. When the threaded sleeve rotates backward, the screws at both ends retract inward to shorten the length of the connecting rod 301. This arrangement can keep the steel-edged rubber waterstop 1 in a flat state, which improves the adaptability of the adjustment component 3.One end of the connecting rod 301 can be fixedly connected to the steel-edged rubber waterstop 1 by welding. One end of the connecting rod 301 has a threaded end on a machine tool. The threaded end passes through a connecting hole, a washer is fitted, and a nut is tightened to fix the connecting rod 301 and the steel-edged rubber waterstop 1. One end of the connecting rod 301 can also be hinged to the steel-edged rubber waterstop 1. The other end of the connecting rod 301 is hinged to a movable sleeve 302. The movable sleeve 302 is threadedly connected to a threaded rod 303. The threaded rod 303 is rotatably connected to a crossbeam 304. One end of the crossbeam 304 is fixedly connected to the reinforcing cage 4 by welding. The other end of the crossbeam 304 can also be fixedly connected to the reinforcing cage 4 by binding. The end of the crossbeam 304 furthest from the reinforcing cage 4 is close to the template 2. When the adjusting component 3 is in its original position, the steel-edged rubber waterstop 1... When the connecting adjustment component 3 is in a flat position, the angle between the left end of the steel-edged rubber waterstop 1 and the central hollow ring is zero. Under external force, the threaded rod 303 rotates clockwise to drive the moving sleeve 302 closer to the template 2 end, causing the left end of the steel-edged rubber waterstop 1 to tilt upwards, forming an angle between the left end of the steel-edged rubber waterstop 1 and the central hollow ring. This allows air (bubbles) at the lower edge of the steel-edged rubber waterstop 1 to overflow (escape) along the tilted steel-edged rubber waterstop 1 during concrete pouring. The threaded rod 303 rotates counterclockwise to drive the moving sleeve 302 away from the template 2 end, causing the tilted steel-edged rubber waterstop 1 to flatten, ensuring the left end of the steel-edged rubber waterstop 1 is in a flat position. This solves the problem of the waterstop not being able to... To address the issue of air leakage from the lower edge of the waterstop during concrete pouring, the angle between one end of the waterstop and the central hollow ring is adjusted. During use, firstly, the steel-edged rubber waterstop 1 is fixed using template 2, ensuring the central hollow ring of the waterstop 1 is positioned in the middle of the expansion joint. Then, one end of the steel-edged rubber waterstop 1 is connected to one end of connecting rod 301, and the other end of connecting rod 301 is hinged to a movable sleeve 302. The movable sleeve 302 is threadedly connected to a threaded rod 303, which is rotatably connected to a crossbeam 304. One end of the crossbeam 304 is connected to a reinforcing cage 4, ensuring the steel-edged rubber waterstop 1 is laid flat. This ensures that the steel-edged rubber waterstop 1 is laid flat when the movable sleeve 302 is in its original position. Afterwards, the operator... The forward rotation of the threaded rod 303 causes the movable sleeve 302 to move closer to the template 2 end, thereby driving the left end of the steel-edged rubber waterstop 1 to tilt upwards, so that the tilted end of the steel-edged rubber waterstop 1 forms a horizontal angle of 15°-30° with the middle hollow ring of the steel-edged rubber waterstop 1. Then, concrete is poured, and vibration is performed while pouring, so that the air at the lower edge of the steel-edged rubber waterstop 1 overflows along the tilted steel-edged rubber waterstop 1 during the concrete pouring process. Then, when the concrete pouring level is flush with the level of the steel-edged rubber waterstop 1, the operator reverses the rotation of the threaded rod 303 to move the movable sleeve 302 away from the template 2 end, so that the tilted end of the steel-edged rubber waterstop 1 is in a flat state, that is, the movable sleeve 302 is in the original position. Finally, the concrete pouring continues.Therefore, the advantage of this embodiment is that, by adopting the above-described configuration, through the mutual cooperation of the connecting rod 301, the movable sleeve 302, the threaded rod 303, and the crossbeam 304, one end of the steel-edged rubber waterstop 1 is raised upwards, forming an angle between the raised end of the steel-edged rubber waterstop 1 and the hollow ring in the middle of the steel-edged rubber waterstop 1. The size of the angle can be adjusted by the distance the movable sleeve 302 moves along the threaded rod 303, so that during the concrete pouring process, air at the lower edge of the steel-edged rubber waterstop 1 can escape along the raised steel-edged rubber waterstop 1.

[0040] A preferred structure of the crossbeam 304 in this embodiment of the invention is as follows: Figure 3 , Figure 4 As shown, a threaded section 305 is fixedly connected to a crossbeam 304. The threaded section 305 and the crossbeam 304 are integrally formed. The threaded section 305 can also be fixedly connected to the crossbeam 304 by welding. The threaded section 305 is located at one end of the threaded rod 303. A lock nut 306 is tightened at the end of the threaded section 305 away from the threaded rod 303. When the lock nut 306 is in the working position, the threaded section 305 and the threaded rod 303 are tightly connected. This arrangement facilitates the tightening of the threaded rod 303. A sliding sleeve 307 is fixedly connected to the end of the lock nut 306 away from the threaded section 305 by welding. The lock nut 306 and the sliding sleeve 307 can also be integrally formed. The sliding sleeve 307 is adapted to the crossbeam 304. The setting of the sliding sleeve 307 can prevent the lock nut 306 from moving along the threaded section 304. The radial movement of the crossbeam 304, i.e., the locking nut 306 deviating from the threaded section 305, means that when the locking nut 306 is threadedly connected to the threaded section 305, the operator needs to align the locking nut 306 and the threaded section 305 before threading. The sliding sleeve 307 saves the operator the step of aligning the locking nut 306 with the threaded section 305, saving time and improving work efficiency. The end of the threaded rod 303 away from the threaded section 305 is provided with a nut 308, which is fixedly connected to the threaded rod 303 by welding. The nut 308 makes it convenient for the operator to rotate the threaded rod 303 with tools. Therefore, the advantage of this embodiment is that the above-mentioned arrangement facilitates the locking of the threaded rod 303 and improves work efficiency.

[0041] A preferred structure of the connecting rod 301 in this embodiment of the invention is as follows: Figure 6As shown, a locking bolt 5 is provided between the connecting rod 301 and the movable sleeve 302. The movable sleeve 302 has a through hole opened by a drilling machine, and the connecting rod 301 has a threaded hole opened by a machine tool. The locking bolt 5 passes through the through hole and is fixedly connected to the connecting rod 301 through the threaded hole, so that the connecting rod 301 is fixedly connected to the movable sleeve 302. When the locking bolt 5 is in the working position, the connecting rod 301 is fixedly connected to the movable sleeve 302. A stable frame is formed between the steel-edged rubber waterstop 1, the connecting rod 301, the locking bolt 5, the movable sleeve 302, the crossbeam 304 and the reinforcing cage 4 to ensure the flat state of the steel-edged rubber waterstop 1 and to prevent the steel-edged rubber waterstop 1 from shifting, rolling and twisting during the concrete pouring process, thus ensuring the water-stopping effect of the steel-edged rubber waterstop 1. Therefore, the advantage of this embodiment is that by adopting the above-mentioned settings, the water-stopping effect of the steel-edged rubber waterstop 1 is guaranteed.

[0042] A preferred structure of template 2 in this embodiment of the invention is as follows: Figure 1 , Figure 5As shown, template 2 includes an upper template 201 and a lower template 202. An annular groove 1 is formed on the upper template 201 near the lower template 202 via a machine tool, extending from one end of the upper template 201 to the other. An annular groove 22 is formed on the lower template 202 near the upper template 201 via a machine tool, extending from one end of the lower template 202 to the other. The hollow ring in the middle of the steel-edged rubber waterstop 1 is located between the annular groove 1 and the annular groove 2. The upper template 201 and the lower template 202 are used for the steel-edged rubber waterstop... The template 2 is positioned and fixed to ensure that the hollow ring in the middle of the steel-edged rubber waterstop 1 is located in the middle of the expansion joint. A protective component 6 is provided at the end of the template 2 furthest from the adjusting component 3. The protective component 6 connects the end of the steel-edged rubber waterstop 1 furthest from the protective component 6 to the template 2; that is, the right end of the steel-edged rubber waterstop 1 is connected to the template 2 through the protective component 6. The protective component 6 includes an arc-shaped component 601, a threaded hole, and a connecting bolt 602. The arc-shaped component 601 is adapted to the steel-edged rubber waterstop 1, and one end of the arc-shaped component 601 is hinged to the template 201. The other end of 601 has a through hole through the machine tool, and the lower template 202 has a threaded hole through the machine tool. The threaded hole corresponds to the through hole. The connecting bolt 602 passes through the through hole and connects to the lower template 202 through the threaded hole. When the protective component 6 is in the working position, the right end of the steel-edged rubber waterstop 1 is connected to the template 2. This setting can prevent the steel edge of the steel-edged rubber waterstop 1 from scratching the operator when the left end of the steel-edged rubber waterstop 1 is poured with concrete, thus improving the safety of the operator. In addition, the setting of the protective component 6 can also prevent the steel edge from scratching the operator. The steel edge at the right end of the rubber waterstop 1 is deformed and twisted, which improves the flatness of the steel-edged rubber waterstop 1. The protective component 6 can also adopt other structures, such as a connecting groove. The connecting groove extends from one end of the template 2 to the other end. The side wall of the connecting groove is provided with through holes and threaded holes. The fixing bolts pass through the through holes of the connecting groove, the through holes of the steel-edged rubber waterstop 1, and the threaded holes of the connecting groove to fix the connecting template 2. Therefore, the advantage of this embodiment is that the above setting improves the safety of the operator and improves the flatness of the steel-edged rubber waterstop 1.

[0043] A method for fixing a steel-edged rubber waterstop includes the aforementioned device for effectively fixing the expansion joint waterstop, and comprises the following steps:

[0044] Step 1: Fix the steel-edged rubber waterstop 1 using template 2, and position the hollow ring in the middle of the expansion joint.

[0045] Step 2: Connect one end of the steel-edged rubber waterstop 1 to one end of the connecting rod 301, and hinge the other end of the connecting rod 301 to the movable sleeve 302. The movable sleeve 302 is threadedly connected to the threaded rod 303, and the threaded rod 303 is rotatably connected to the crossbeam 304. One end of the crossbeam 304 is connected to the reinforcing cage 4, so that the steel-edged rubber waterstop 1 is in a flat state when the movable sleeve 302 is in the initial position. The connecting rod 301 is fixedly connected to the movable sleeve 302 by the locking bolt 5.

[0046] Step 3: Using the arc-shaped component 601, the end of the steel-edged rubber waterstop 1 away from the connecting rod 301 is brought closer to the lower template 202, and the arc-shaped component 601 is connected to the lower template 202 by the connecting bolt 602. The setting of the arc-shaped component 601 makes the right end of the steel-edged rubber waterstop 1 bend in an arc shape.

[0047] Step 4: When pouring concrete, loosen the locking bolt 5. The operator uses a tool to rotate the threaded rod 303 to move the movable sleeve 302 toward the template 2 end. The movable sleeve 302 drives the connecting rod 301 to make the steel edge rubber waterstop 1 tilt upwards near the end of the connecting rod 301, and make the tilted end of the steel edge rubber waterstop 1 form a horizontal angle of 15°-30° with the middle hollow ring of the steel edge rubber waterstop 1.

[0048] Step 5: The operator rotates the locking nut 306 to connect the locking nut 306 to the threaded section 305. The operator continues to rotate the locking nut 306 to connect the locking nut 306 to the threaded rod 303 near the end of the threaded rod 303, thus securing the threaded section 305 and the threaded rod 303 together. While the locking nut 306 is rotating to connect the threaded rod 303, the operator uses a tool with their other hand to keep the threaded rod 303 in a fixed position, making it easier for the locking nut 306 to connect the threaded rod 303.

[0049] Step Six: Pour concrete onto the steel-edged rubber waterstop 1 at the left end of template 2. When the concrete pouring surface is level with the horizontal surface of the steel-edged rubber waterstop 1, the operator loosens the locking nut 306 and reverses the threaded rod 303 to move the movable sleeve 302 away from template 2, so that the raised end of the steel-edged rubber waterstop 1 is flattened and placed in a flat position. The moving sleeve 302 is fixedly connected to the connecting rod 301 by the locking bolt 5, and the concrete pouring continues. In this step, the steel-edged rubber waterstop 1 can be placed in a flat position, or the raised end of the steel-edged rubber waterstop 1 can be left flat according to the construction requirements.

[0050] Step 7: After the concrete has solidified, unscrew the connecting bolt 602 to open the arc-shaped part 601, so that the steel-edged rubber waterstop 1 is opened away from the end (right end) of the connecting rod 301, and remove the upper formwork 201 and the lower formwork 202 for reuse.

[0051] Step 8: Connect the open end of the steel-edged rubber waterstop 1 to one end of another connecting rod 301. Hinge the other end of the connecting rod 301 to another movable sleeve 302. Thread the movable sleeve 302 to another threaded rod 303. Rotate the threaded rod 303 to another crossbeam 304. Connect one end of the crossbeam 304 to the reinforcing cage 4. Repeat the pouring process of the left end of the steel-edged rubber waterstop 1 to complete the pouring of the entire steel-edged rubber waterstop 1.

[0052] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
