Description

Technical Field

[0001] This utility model is a positioning device for pile foundation steel cage for building reinforcement, belonging to the technical field of building reinforcement equipment. Background Technology

[0002] In the construction of bridges and high-rise buildings, a large number of pile foundations are required to improve their stability. The pile foundation installation process mainly includes drilling, lowering the reinforcing cage, and pouring concrete, which then solidifies to form the pile foundation. The reinforcing cage consists of main bars and reinforcing rings. The main bars are arranged vertically, and the reinforcing rings are fitted onto the main bars and fixed by welding. During the lowering of the reinforcing cage, any deviation in the center of the cage reduces the strength and stability of the pile foundation.

[0003] Publication number CN217150250U discloses a positioning device for a pile foundation reinforcement cage for building reinforcement. The device comprises a jacking mechanism consisting of a pipe column, a telescopic rod, a piston, and a compression spring. Under the pressure of liquid or gas within the pipe column, the piston slides, driving the telescopic rod to move while simultaneously compressing the compression spring. This causes the free end of the telescopic rod to press against the inner wall of the borehole. When the liquid or gas pressure within the pipe column is removed, the telescopic rod retracts under the action of the compression spring. By setting two sets of jacking rings and the jacking mechanism, multi-point support is formed, which is beneficial for the stable support of the reinforcement cage, ensuring that the reinforcement cage is coaxial with the borehole. However, if the jacking mechanism extends into the reinforcement cage at the same offset angle to support it, tilting may occur, thus failing to provide any assistance in correcting the center deviation of the reinforcement cage. Therefore, there is an urgent need for a positioning device for a pile foundation reinforcement cage for building reinforcement to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a positioning device for a pile foundation reinforcement cage for building reinforcement, thereby solving the problems mentioned in the background art. This utility model uses a counterweight block assembly to center the reinforcement cage, so that the reinforcement cage will not be centrally offset when it is lowered into the pile foundation trench of the building. At the same time, it can also be poured without disassembly, thus facilitating the subsequent pouring of concrete for the pile foundation reinforcement cage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for a pile foundation reinforcement cage for building reinforcement, comprising a reinforcement cage body, a second counterweight, a first counterweight, a mounting cover plate, and inclined reinforcing bars. The reinforcement cage body is composed of multiple outer reinforcing bar rings, multiple reinforcing bars, and multiple inner reinforcing bar rings. The multiple inner reinforcing bar rings are horizontally welded inside the multiple reinforcing bars, and the multiple outer reinforcing bar rings are horizontally welded outside the multiple reinforcing bars. The first counterweight is located in the lower middle of the inside of the reinforcement cage body. An installation groove is provided at the upper end of the first counterweight, and an inner counterweight core is fixed in the installation groove. A diamond-shaped positioning groove is provided in the middle of the upper end of the inner counterweight core. The second counterweight is located above the first counterweight. A mounting cover plate is horizontally fixed at the lower end of the second counterweight. A sealing plate is fixed in the middle of the lower end of the mounting cover plate, and a diamond-shaped positioning bar is longitudinally fixed in the middle of the lower end of the sealing plate. The mounting cover plate is installed on the upper side of the first counterweight by multiple flange bolts. Multiple inclined reinforcing bars are provided.

[0006] Furthermore, multiple inclined reinforcing bars are inclinedly welded between the upper inner reinforcing ring and the upper outer reinforcing ring, and each of the multiple inclined reinforcing bars has a longitudinally welded lifting ring at its upper end.

[0007] Furthermore, the rhomboid positioning rod is inserted into the rhomboid positioning groove.

[0008] Furthermore, the sealing sheet is positioned horizontally within the mounting groove.

[0009] Furthermore, multiple inclined reinforcing bars are respectively welded inclined around the upper end of the mounting cover plate.

[0010] Furthermore, each of the upper outer sides of the plurality of inclined reinforcing bars is welded with an arc-shaped welding piece, and the other side of the plurality of arc-shaped welding pieces is welded and fixed to one of the inner reinforcing bar rings.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a positioning device for a pile foundation reinforcement cage for building reinforcement. Because it incorporates an outer reinforcing ring, a reinforcing rod, an inner reinforcing ring, a welded lifting ring, an inclined reinforcing bar, a first counterweight block, an inner counterweight core, a mounting cover plate, a second counterweight block, an inclined reinforcing rod, and an arc-shaped welded plate, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The use of the counterweight block assembly for center positioning of the reinforcement cage prevents center deviation when the cage is lowered into the building pile foundation trench. Furthermore, it allows for concrete pouring without disassembly, facilitating subsequent concrete pouring and not affecting subsequent work efficiency. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a positioning device for a pile foundation reinforcement cage for building reinforcement, comprising a reinforcement cage body 1, a second counterweight 15, a first counterweight 7, an installation cover plate 13, and inclined reinforcing bars 16. The reinforcement cage body 1 is composed of multiple outer reinforcing bar rings 2, multiple reinforcing bars 3, and multiple inner reinforcing bar rings 4. The multiple inner reinforcing bar rings 4 are horizontally welded inside the multiple reinforcing bars 3, and the multiple outer reinforcing bar rings 2 are horizontally welded outside the multiple reinforcing bars 3. The first counterweight 7 is located in the lower middle part inside the reinforcement cage body 1, and an installation groove 8 is provided at the upper end of the first counterweight 7. An inner counterweight core 9 is fixed inside, and a diamond-shaped positioning groove 10 is opened in the middle of the upper end of the inner counterweight core 9. The second counterweight block 15 is located above the first counterweight block 7. A mounting cover plate 13 is horizontally fixed at the lower end of the second counterweight block 15. A sealing plate 12 is fixed in the middle of the lower end of the mounting cover plate 13. A diamond-shaped positioning rod 11 is longitudinally fixed in the middle of the lower end of the sealing plate 12. The mounting cover plate 13 is installed on the upper side of the first counterweight block 7 by multiple flange bolts 14. Multiple inclined steel bar rods 16 are provided. This design solves the problem that when the original device tilts, it cannot play any auxiliary role in the center deviation of the steel cage.

[0019] As the first embodiment of this utility model: multiple inclined reinforcing bars 6 are inclinedly welded between the upper inner reinforcing bar ring 4 and the upper outer reinforcing bar ring 2. Each of the multiple inclined reinforcing bars 6 has a longitudinally welded lifting ring 5 at its upper end. By adding multiple inclined reinforcing bars 6, the connection between the upper inner reinforcing bar ring 4 and the upper outer reinforcing bar ring 2 can be made more secure. In addition, the setting of multiple welded lifting rings 5 ​​makes it easier for external suspension equipment to lift the reinforcing bar cage 1.

[0020] A rhomboid positioning rod 11 is inserted into a rhomboid positioning groove 10, and a sealing plate 12 is horizontally positioned in an installation groove 8. The addition of the sealing plate 12 horizontally positioned in the installation groove 8 and the rhomboid positioning rod 11 inserted into the rhomboid positioning groove 10 ensures the accuracy of the installation cover plate 13 above the first counterweight block 7. Multiple inclined reinforcing bars 16 are respectively inclinedly welded to the upper perimeter of the installation cover plate 13. Each of the upper outer sides of the multiple inclined reinforcing bars 16 is welded with an arc-shaped welding piece 17. The other side of the multiple arc-shaped welding pieces 17 is welded and fixed to one of the inner reinforcing bar rings 4. The addition of multiple inclined reinforcing bars 16 facilitates the welding of the other end of the installation cover plate 13 to the lower end of the inner part of the reinforcing cage 1 via the arc-shaped welding pieces 17.

[0021] As a second embodiment of this utility model: In actual use, the device uses an external suspension device to hook multiple welded lifting rings 5 ​​and lift the steel cage 1 steadily. The steel cage 1 will be vertically tilted downwards due to the position and center of gravity of the second counterweight 15, the inner counterweight core 9 and the first counterweight 7. When the steel cage 1 is completely vertical and there is no shaking, it can be slowly moved longitudinally into the pile foundation trench of the building. After completion, it can be used to pour concrete for the reinforcement of the building pile foundation.
