Description

Technical Field

[0001] This application belongs to the technical field of bridge construction, and more specifically, relates to a device for preventing the grouting of steel cages from floating. Background Technology

[0002] Before pouring concrete for high-speed railway pile foundations, a reinforcing cage needs to be placed inside the pile foundation before concrete is poured into it. During concrete pouring, the reinforcing cage needs to be restrained to prevent it from floating due to the back pressure of the concrete.

[0003] Current devices for preventing the grouting cage from floating include a frame erected above the pile foundation, with two horizontally inserted rods on the frame and two lower pressure plates installed inside the pile foundation. The lower ends of the lower pressure plates abut against the top of the rebar cage, and the lower pressure plates have multiple positioning holes for the inserted rods to pass through. By inserting the rods into the corresponding positioning holes in the lower pressure plates, the rods are kept in a height-limited position relative to the rebar cage.

[0004] If, after the lower end of the pressure plate contacts the top of the reinforcing cage, there is no positioning hole on the pressure plate directly aligned with the insertion rod, then the pressure plate can only be raised upwards until the positioning hole is directly aligned with the insertion rod for insertion. However, this will cause the reinforcing cage to float upwards, affecting the construction quality. Utility Model Content

[0005] The purpose of this application is to provide a device for preventing the grouting cage from floating, in order to solve the technical problem in the prior art that if there is no positioning hole on the lower pressure plate that is directly aligned with the insertion rod, the lower pressure plate can only be raised upwards until the positioning hole is directly aligned with the insertion rod for the insertion rod to be inserted, which will cause the grouting cage to float upwards and affect the construction quality.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a device for preventing the grouting cage from floating, comprising a frame and two pressure plates. The frame is erected on the pile foundation, the bottom end of the pressure plate is used to press against the top of the rebar cage, and the top end is located inside the frame. Multiple insertion holes are provided on the pressure plate along the vertical direction. The device for preventing the grouting cage from floating further includes: Two insertion rods, each corresponding to one of the two pressure plates, are used to insert into the insertion holes; and An adjustment assembly is provided on the frame and has one set at each end of each of the insert rods. The adjustment assembly is used to adjust the height of the end of the insert rod. In one possible implementation, based on the above technical solutions, the adjustment component includes: A fixing frame is installed on the frame body; A lifting frame, slidably disposed within the fixed frame and connected to the insert rod; and An adjusting screw is vertically threaded onto the fixed frame, and the bottom of the adjusting screw is rotatably connected to the lifting frame.

[0007] In conjunction with the above technical solutions, in one possible implementation, the adjustment component further includes: A connecting plate is rotatably connected to the bottom of the adjusting screw, and the connecting plate is fixed to the lifting frame; and An auxiliary spring is sleeved on the adjusting screw and located inside the fixed frame; the bottom end of the auxiliary spring is connected to the connecting plate, and the top end of the auxiliary spring is connected to the top of the fixed frame.

[0008] In one possible implementation, based on the above technical solutions, the lifting frame is provided with a socket for inserting the rod along its own length.

[0009] In one possible implementation, based on the above technical solutions, the socket and the fixing bracket have an opening on the same side for the insertion rod to be inserted laterally.

[0010] In one possible implementation, based on the above technical solutions, the fixing frame is detachably connected to the frame body by bolts.

[0011] In one possible implementation, based on the above technical solutions, the bottom end of the pressure plate is provided with a limiting claw, which is used to lock onto the top of the reinforcing cage.

[0012] In one possible implementation, based on the above technical solutions, the frame is composed of multiple welded steel pipes.

[0013] The beneficial effects of the anti-reinforcing cage grouting floating device provided in this application are as follows: Compared with the prior art, when the insertion hole on the pressure plate is not aligned with the insertion rod due to the height of the reinforcing cage, the height of the insertion rod can be adjusted by adjusting the component to align it with any insertion hole, so that the insertion rod can be inserted into the insertion hole. This allows the pressure plate to limit the reinforcing cage. Furthermore, after the insertion rod is inserted into the insertion hole, the construction personnel can adjust the component to make the insertion rod have a downward pressing tendency on the pressure plate, thereby improving the stability of the pressure plate in limiting the reinforcing cage. This effectively prevents the reinforcing cage from floating, further ensuring the smooth progress of the construction process and the reliability of the construction quality.

[0017] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] It should be further noted that the accompanying drawings and embodiments of this application mainly describe the concept of this application. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of this application, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0019] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0020] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0022] The device for preventing the grouting cage from floating is described in this application.

[0023] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a device for preventing the grouting cage from floating, including a frame 1, two pressure plates 2, two insertion rods 3 and four sets of adjustment components 4; the frame 1 is erected on the pile foundation, the two pressure plates 2 are located on opposite sides of the rebar cage, the bottom end of the pressure plate 2 is used to press against the top of the rebar cage, and the top end is located inside the frame 1, and multiple insertion holes 21 are opened on the pressure plate 2 along the vertical direction.

[0024] Two insertion rods 3 correspond one-to-one with two pressure plates 2. The insertion rods 3 are used to insert into the insertion holes 21. Adjustment components 4 are set on the frame 1, and there is one set at each end of each insertion rod 3. The adjustment components 4 are used to adjust the height of the end of the insertion rod 3.

[0025] Compared with the prior art, the anti-reinforcing cage grouting floating device provided in this embodiment can adjust the height of the insertion rod 3 by adjusting the component 4 when the insertion hole 21 on the pressure plate 2 is not aligned with the insertion rod 3 due to the height of the reinforcing cage. This allows the insertion rod 3 to be aligned with any insertion hole 21, so that it can be inserted into the insertion hole 21. The pressure plate 2 can then limit the reinforcing cage. Furthermore, after the insertion rod 3 is inserted into the insertion hole 21, the construction personnel can adjust the component 4 to make the insertion rod 3 have a downward pressing tendency on the pressure plate 2, thereby improving the stability of the pressure plate 2 in limiting the reinforcing cage. This effectively prevents the reinforcing cage from floating, further ensuring the smooth progress of the construction process and the reliability of the construction quality.

[0026] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjustment assembly 4 includes a fixed frame 41, a lifting frame 42, and an adjusting screw 43; the fixed frame 41 is mounted on the frame 1; the lifting frame 42 is slidably mounted inside the fixed frame 41 and connected to the insert rod 3; the adjusting screw 43 is vertically threaded onto the fixed frame 41, and the bottom of the adjusting screw 43 is rotatably connected to the lifting frame 42.

[0027] Specifically, in this embodiment, a handwheel is coaxially provided on the top of the adjusting screw 43.

[0028] By rotating the handwheel to turn the adjusting screw 43, the rotational motion can be converted into the linear motion of the lifting frame 42 using the principle of threaded transmission, thereby achieving precise adjustment of the height of the insertion rod 3. Furthermore, the threaded connection has a self-locking function, meaning that after the adjusting screw 43 stops rotating, it can maintain its current position and will not move on its own due to external forces, ensuring the stability of the insertion rod 3 after height adjustment.

[0029] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The adjustment assembly 4 also includes a connecting plate 44 and an auxiliary spring 45; the connecting plate 44 is rotatably connected to the bottom of the adjusting screw 43 and fixed to the lifting frame 42; the auxiliary spring 45 is sleeved on the adjusting screw 43 and located inside the fixed frame 41; the bottom end of the auxiliary spring 45 is connected to the connecting plate 44 and the top end of the auxiliary spring 45 is connected to the top of the fixed frame 41.

[0030] During the adjustment of the height of the insertion rod 3, the auxiliary spring 45 can assist the adjustment of the adjusting screw 43 to a certain extent. When the adjusting screw 43 rotates, the auxiliary spring 45 can provide additional elastic force, making the movement of the lifting frame 42 more stable and smooth. When the reinforcing cage is subjected to the recoil force of concrete, the auxiliary spring 45 can play a buffering role, reducing the direct impact of the recoil force on the adjusting component 4, protecting the adjusting component 4 from damage, and further improving the reliability and stability of the device.

[0031] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The lifting frame 42 has an insertion port 421 for inserting the rod 3 along its own length.

[0032] During construction, the insertion rod 3 can be easily inserted into the lifting frame 42 through the insertion port 421, realizing a quick connection between the insertion rod 3 and the lifting frame 42. This makes the installation process of the insertion rod 3 simple and quick, reducing construction time and labor intensity.

[0033] Meanwhile, the design of the insertion port 421 can also ensure the accurate and stable position of the insertion rod 3 within the lifting frame 42, ensuring that the insertion rod 3 can move up and down synchronously with the movement of the lifting frame 42, thereby achieving effective adjustment of the height of the steel cage.

[0034] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The socket 421 and the fixing bracket 41 have an opening on the same side for the insertion rod 3 to be inserted laterally.

[0035] The lateral insertion opening allows the insert rod 3 to be directly inserted into the socket 421 and the fixing bracket 41 from the side, eliminating the need to slowly insert the insert rod 3 from one end along its length, thus greatly shortening the installation time. In construction environments with limited space, this lateral insertion method is more flexible and can adapt to different construction conditions.

[0036] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The fixing frame 41 is detachably connected to the frame body 1 by bolts.

[0037] During installation, the mounting bracket 41 can be securely fixed to the frame 1 using bolts, ensuring the stable operation of the adjustment component 4. When maintenance, repair, or replacement of parts is required, the bolts can be easily removed to detach the mounting bracket 41 from the frame 1, improving the maintainability of the device.

[0038] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The bottom end of the pressure plate 2 is provided with a limit claw, which is used to lock onto the top of the steel cage.

[0039] Specifically, in this embodiment, the limiting claw is an inverted U-shaped plate, and the top of the reinforcing cage is locked inside the U-shaped plate.

[0040] The limiting claws further enhance the device's fixing effect on the reinforcing cage, accurately locking into the top of the cage and increasing the contact area and friction between the pressure plate 2 and the reinforcing cage, allowing the pressure plate 2 to more firmly press against the cage. During concrete pouring, the limiting claws effectively prevent the reinforcing cage from shifting or swaying horizontally, further improving its stability.

[0041] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The frame 1 is composed of multiple welded steel pipes.

[0042] Steel pipes possess high strength and rigidity, enabling them to withstand significant pressure and impact. The frame structure 1, composed of multiple welded steel pipes, is robust and provides stable support for the entire anti-reinforcing steel cage grouting and floating device. Furthermore, the steel pipe material exhibits good corrosion resistance, allowing for prolonged use in harsh construction environments and extending the service life of the frame structure 1. In addition, the steel pipe welded frame structure 1 has a relatively simple manufacturing process, low cost, and is easy to produce and apply, thus improving the economic efficiency and practicality of the device.

[0043] The above are merely preferred embodiments of this application and are not intended to limit this application.
