[0002] In building basements and civil defense projects, water-stop rings need to be installed on the anchored steel bars at the top of the piles to prevent water from seeping along the steel bars and achieve the purpose of water stoppage and seepage prevention. In the existing technology, water-stop rings are usually installed manually. Due to the rough surface of the steel bars, the friction between the steel bars and the water-stop ring is large, and the steel bars are also long, which makes the installation of water-stop rings difficult and inefficient. Especially in areas with dense steel bars, the cross-section of the steel bar head can easily scratch workers, seriously affecting construction safety, construction efficiency, and the installation quality of the water-stop rings. Summary of the Invention

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figure 1 As shown in the figure, an embodiment of the present invention proposes a portable rebar waterstop ring installation device, including a sleeve 1, a tie rod assembly 2, and an elastic assembly 3; the sleeve 1 is used to sleeve the rebar to which the waterstop ring 4 is to be installed, and one end of the sleeve is provided with a connecting part 11 for passing the waterstop ring 4 through; the elastic assembly 3 is slidably connected to the connecting part 11 for pushing the waterstop ring 4; the tie rod assembly 2 is movably connected to the sleeve 1 for abutting against the waterstop ring 4.

[0027] It should be noted that the embodiments of this application are used to install a water-stop ring 4 on the pile top anchoring reinforcement. The pile top anchoring reinforcement refers to the longitudinal reinforcing steel bars that extend from the top of the pile foundation and anchor into the upper pile cap or raft slab, used to reliably connect the pile to the pile cap or raft slab. In some other embodiments of this application, the device can also be used in other structures requiring the installation of water-stop rings 4 in building basements and civil defense projects, exemplarily for threaded rods passing through the building structure.

[0028] The sleeve 1 in this application is used to be sleeved on the outside of the anchoring steel bar. It can be a hollow tubular structure or a rod-shaped structure with a cavity at one end. The diameter of the cavity is adapted to the diameter of the steel bar on which the water-stop ring 4 is to be installed, so that it can be smoothly sleeved on the outside of the steel bar.

[0029] In this embodiment, the water-swellable ring 4 is made of water-swellable rubber and is ring-shaped. In use, the elasticity of the rubber itself is used to stretch the water-swellable ring 4, and then the sleeve part 11 is inserted into the deformed water-swellable ring 4, so that the water-swellable ring 4 is fitted on the end of the sleeve 1, that is, the outside of the sleeve part 11. The water-swellable ring 4 is moved to one side, so that it presses against the elastic component 3 until the elastic component 3 is in a set compression state. Then, the pull rod assembly 2 is used to hold the water-swellable ring 4 and fix the water-swellable ring 4 in a set position. Then, the sleeve 1 is fitted on the root of the steel bar, so that one end of the sleeve part 11 is kept at a set distance from the root of the steel bar. Then, the pull rod assembly 2 is controlled to move away from the water-swellable ring 4, and the water-swellable ring 4 moves towards the fitting end under the elastic force of the elastic component 3 until it leaves the sleeve 1 and fits on the root of the steel bar. Since the diameter of the steel bar is smaller than the diameter of the sleeve 1, the water-swellable ring 4 rebounds and sticks tightly to the surface of the steel bar, forming a physical seal in the initial state.

[0030] The above technical solution allows for quick and convenient installation of the water-stop ring 4 on the outside of the reinforcing bar. Compared to the existing method of moving the water-stop ring 4 along the length of the reinforcing bar to its root, this method fundamentally avoids the problem of excessive friction between the water-stop ring 4 and the reinforcing bar, which makes installation difficult. This significantly reduces the installation difficulty of the water-stop ring 4 and improves installation efficiency. Furthermore, during installation, the operator's hands will not come into contact with the reinforcing bar, preventing scratches and improving construction safety. Additionally, the device in this application requires less space, solving the problem of insufficient working surface when manually installing the water-stop ring 4 in areas with dense reinforcing bar distribution.

[0031] Furthermore, in this embodiment, the sleeve 1 further includes a first fixing part 12 and a second fixing part 13; the first fixing part 12 is close to the sleeve part 11, and the second fixing part 13 is away from the sleeve part 11; the pull rod assembly 2 includes a locking member 21 and a driving member 22, the locking member 21 is hinged to the first fixing part 12 and connected to the driving member 22; the driving member 22 is connected to the second fixing part 13 and is used to drive the locking member 21 to move closer to or away from the sleeve part 11. With this setting, when the operator controls the driving member 22, their hand is away from the root of the reinforcing bar, making operation easier; the locking member 21 is hinged to the first fixing part 12, making the overall structure more stable and easier to control the locking member 21 to lock or unlock the water-stop ring 4.

[0032] The first fixing part 12 and the second fixing part 13 are arranged along the length of the sleeve 1 and are used as the mounting base for the tie rod assembly 2. The first fixing part 12 is located close to the sleeve part 11, that is, when in use, the first fixing part 12 is closer to the root of the rebar. The second fixing part 13 is located at the end of the sleeve 1 away from the sleeve part 11, which makes it convenient for the operator to control the movement of the drive component 22. Preferably, the length of the sleeve 1 is greater than the length of the rebar exposed at the top of the pile, so that the entire rebar is placed inside the sleeve 1, avoiding the rebar head from scratching the operator.

[0033] The aforementioned locking member 21 is hinged to the first fixing part 12. Under the action of the driving member 22, the locking member 21 can rotate around the hinge point between itself and the first fixing part 12, thereby switching between different states according to usage requirements. For example, when the water-stop ring 4 is installed in the sleeve part 11, it is necessary to lock the water-stop ring 4 using the locking member 21. At this time, the driving member 22 controls the locking member 21 to move closer to the sleeve part 11, so that the locking member 21 can press against the water-stop ring 4. When the sleeve 1 is located at the set position at the root of the reinforcing bar, it is necessary to release the locking member 21 from the water-stop ring 4. At this time, the driving member 22 controls the locking member 21 to move away from the sleeve part 11, so that the locking member 21 can be separated from the water-stop ring 4, so that the water-stop ring 4 can move under the action of the elastic component 3. The hinged connection makes the overall structure of the locking member 21 stable and easier to control.

[0034] Furthermore, in one alternative technical solution of the above embodiments, such as Figure 1 As shown, the locking member 21 includes a pressing part 211, a first hinge part 212, and a first connecting part 213 connected in sequence; the first hinge part 212 is hinged to the first fixing part 12; the connecting part is connected to the driving member 22. The pressing part 211 is used to press against the water-stop ring 4. Through the action of the driving member 22, the connecting member is driven to rotate around the first hinge part 212, so that one end of the pressing part 211 approaches or moves away from the sleeve part 11, thereby locking or releasing the locking of the water-stop ring 4.

[0035] Specifically, the pressing part 211 has an L-shaped structure, including a limiting horizontal bar and a limiting vertical bar. The limiting vertical bar is connected to the hinge part, and the pressing part 211 rotates with the limiting vertical bar as the radius. When the pressing part 211 approaches the water-stop ring 4, the limiting horizontal bar can be perpendicular to the sleeve 1 and extend into the bottom end of the water-stop ring 4, thereby supporting the water-stop ring 4. The two form a sufficient contact area to achieve effective limiting of the water-stop ring 4.

[0036] Furthermore, in the above embodiment, the first connecting part 213 is provided with a first buckle 214, the first fixing part 12 is provided with a first sliding groove 121, and the first buckle 214 is slidably connected to the first sliding groove 121. The first buckle 214 can slide along the first slide groove 121 and engage with it, preventing it from shifting to either side of the first slide groove 121 during sliding, thus improving the connection stability between the locking member 21 and the first fixing part 12. By setting the first slide groove 121, the movement range of the first buckle 214 is limited, thereby limiting the rotation path of the limiting crossbar, making it easier to control the locking of the locking member 21 on the water-stop ring 4. For example, the connecting part is perpendicular to the limiting longitudinal bar, and the first slide groove 121 is an arc-shaped groove whose radius is adapted to the length of the connecting part. When the first buckle 214 moves to the bottom end of the first slide groove 121, the limiting crossbar is perpendicular to the sleeve part 11, forming an effective limit on the water-stop ring 4. When the first buckle 214 moves to the top end of the first slide groove 121, the limiting crossbar is able to move away from the water-stop ring 4 by a sufficient distance to avoid the movement path of the water-stop ring 4.

[0037] Furthermore, in an alternative technical solution of the above embodiment, the driving member 22 includes a rocker arm 221, a second hinge portion 222, a second connecting portion 223, and a connecting rod 224 connected in sequence; the second hinge portion 222 is hinged to the second fixed portion 13; the second connecting portion 223 is hinged to one end of the connecting rod 224, and the other end of the connecting rod 224 is hinged to the first latch 214. The rocker arm 221 is convenient for manual control by the operator. By pulling the rocker arm 221, the second connecting portion 223 can be driven to rotate around the second hinge portion 222, thereby driving the connecting rod 224 and the first latch 214 to move, realizing the linkage control of the locking member 21.

[0038] Furthermore, the second connecting part 223 is provided with a second buckle 225, and the second fixing part 13 is provided with a second sliding groove 131. The second buckle 225 is slidably connected to the second sliding groove 131. Similarly, the second buckle 225 can slide along the second sliding groove 131 and engage with the second sliding groove 131, and will not shift to either side of the second sliding groove 131 during sliding, thereby improving the connection stability between the driving member 22 and the second fixing part 13. One end of the connecting rod 224 is hinged to the second buckle 225. By setting the second sliding groove 131, the movement range of the second buckle 225 is limited, thereby limiting the rotation path of the connecting rod 224, and ultimately limiting the rotation range of the locking member 21.

[0039] In one specific embodiment, the second slide groove 131 and the first slide groove 121 are arc-shaped grooves with the same shape and extension direction, and are arranged vertically correspondingly; the first hinge portion 212 and the second hinge portion 222 are arranged vertically correspondingly, and the first connecting portion 213 and the second connecting portion 223 are arranged vertically correspondingly; the end of the rocker arm 221 away from the second hinge portion 222 is provided with a handle, so that the operator can hold the handle and pull the rocker arm 221, so that the second latch 225 swings back and forth in the second slide groove 131, and then drives the first latch 214 to swing back and forth synchronously in the second slide groove 131 through the connecting rod 224.

[0040] Furthermore, in this embodiment, the elastic component 3 includes an elastic element 31 and a slider 32. One end of the elastic element 31 is connected to the sleeve portion 11, and the other end is connected to the slider 32. The slider 32 is slidably connected to the sleeve portion 11. The slider 32 is used to abut against the top end of the water-stop ring 4 so that after the locking member 21 releases the lock on the water-stop ring 4, the water-stop ring 4 is pushed along the sleeve portion 11 by the elastic force of the elastic element 31, so that the water-stop ring 4 is disengaged from the sleeve 1 and transferred to the root of the reinforcing bar.

[0041] Furthermore, in the above embodiment, the first fixing part 12 is provided with a limiting groove 122, and a limiting member 123 is slidably connected in the limiting groove 122, and the limiting member 123 is connected to the slider 32. The limiting groove 122 is used to limit the movement range of the limiting member 123, thereby limiting the movement range of the slider 32. At the same time, it can also help limit the initial installation position of the water-stop ring 4 in the sleeve 11, making the compression degree of the elastic member 31 easier to control. For example, when installing the water-stop ring 4, the water-stop ring 4 is pushed and the slider moves synchronously away from the sleeve end until the limiting member 123 moves to the top of the limiting groove 122, and the locking member 21 locks the water-stop ring 4. After the sleeve 1 is inserted into the set position of the steel bar, the locking member 21 is used to release the lock on the water-stop ring 4. The slider 32 pushes against the water-stop ring 4 under the action of elasticity and drives the limiting member 123 to slide along the limiting groove 122. When the slider 32 slides to the end of the sleeve 11, the limiting member 123 just moves to the bottom end of the limiting groove 122 to limit the slider 32 to slide further downward and prevent the slider 32 from falling off the sleeve 1.

[0042] Furthermore, in order to ensure that both the slider 32 and the water-stop ring 4 can slide smoothly along the sleeve 11, the sleeve 11 is provided with lubricating oil to reduce the friction between the slider 32 and the water-stop ring 4 and the sleeve 11, so that the elastic element 31 can provide sufficient elastic force, the slider 32 can move to the bottom end of the sleeve 1, thereby ensuring that the water-stop ring 4 can be transferred to the reinforcing bar.

[0043] In the above embodiment, in order to ensure the accurate installation position of the water-stop ring 4, after the water-stop ring 4 is transferred to the reinforcing bar, the end of the sleeve 1 can be used to press the water-stop ring 4 so that the water-stop ring 4 fits against the top of the pile structure. Then the whole device can be moved to the next place for use.

[0044] In one specific embodiment, the end of the sleeve 1 away from the sleeve part 11 is also provided with a handle 5 to facilitate the operator to hold, use and move it.

[0045] This application also proposes a method for using the above-mentioned portable steel reinforcement waterstop ring installation device, including:

[0046] S1. Install the water-stop ring 4 on the sleeve 11 of the sleeve 1, and lock the water-stop ring 4 by the locking member 21;

[0047] Before installing the water-stop ring 4, apply lubricating oil to the outside of the sleeve 11 to ensure that the slider 32 can slide smoothly; stretch and deform the water-stop ring 4 and put it on the sleeve 11, and push the water-stop ring 4 to make the slider 32 slide along the sleeve 11 toward the elastic member 31 to compress the elastic member 31; then control the locking member 21 to rotate to the set position to lock the water-stop ring 4.

[0048] S2. Install the sleeve 1 on the outside of the reinforcing bar;

[0049] After the sleeve 1 is in place, the bottom end of the sleeve 1 should maintain a certain distance from the root of the reinforcing bar to reserve enough installation space for the water-stop ring 4.

[0050] S3. The locking component is controlled by the driving component 22 to release the locking of the water-stop ring 4;

[0051] Rotate the drive component 22 to separate the locking component from the water-stop ring 4; the slider 32 pushes the water-stop ring 4 downward under the elastic force of the elastic component 31 until it is fitted into the preset position of the reinforcing bar, and uses the end of the sleeve 1 to press the water-stop ring 4 so that the water-stop ring 4 fits against the top of the pile structure.

[0052] Repeat steps S1-S3 to complete the installation of the waterstop ring 4 for all the steel bars on the pile structure.

[0053] The advantages and positive effects of this invention are:

[0054] (1) By using the portable steel bar waterstop ring installation device in this application, the waterstop ring can be installed on the outside of the steel bar quickly and conveniently, which greatly reduces the installation difficulty of the waterstop ring and improves the installation efficiency;

[0055] (2) During the installation of the water-stop ring, the operator's hands will not come into contact with the steel bars, thus avoiding being scratched by the steel bars and improving the safety of construction.

[0056] (3) The device in this application requires less space and can be applied to areas with dense steel reinforcement, thus solving the problem of insufficient working surface when manually installing the water-stop ring;

[0057] (4) The overall device has a simple structure, is easy to manufacture, has a stable connection, is easy to use and control, and ensures the installation quality of the water-stop ring.

[0058] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
