Description

A device for preventing the displacement of building pile foundations Technical Field

[0001] This utility model relates to the field of foundation pile construction technology, specifically a device for preventing the displacement of building pile foundations. Background Technology

[0002] In the construction of building pile foundations, the reinforcing cage is a key component constituting the main structure of the pile foundation. As the load-bearing skeleton of the pile foundation, the reinforcing cage, through its synergistic effect with concrete, can significantly enhance the compressive and shear resistance of the pile foundation, ensuring its stability when bearing the load of the superstructure. Therefore, in pile foundation construction, the precise installation of the reinforcing cage is a crucial step in ensuring the quality of the pile foundation, and its accurate positioning directly affects the safety of the entire building foundation.

[0003] However, during the concrete pouring process of pile foundations, the reinforcing cage is often affected by factors such as the impact force generated by the flow of concrete, the vibration of the pouring equipment, and the stress changes of the surrounding soil, causing its position to shift. Once the reinforcing cage deviates from the design center position, it will not only cause uneven stress on the pile foundation section and reduce the bearing capacity of the pile foundation, but may also cause problems such as failure of the connection between the pile foundation and the superstructure, thus creating potential structural safety hazards for the building project. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preventing the displacement of building pile foundations, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a building pile foundation anti-deviation device, comprising a base plate, an array of guide grooves formed on the upper end of the base plate, guide blocks slidably connected in each guide groove, a traction shaft fixedly connected to the upper end of each guide block, a baffle fixedly connected to the upper end of the base plate, a plurality of arrayed limiting blocks fixedly connected to the upper end of the baffle, a traction rope slidably connected to each limiting block, mounting seats rotatably connected to both ends of the traction rope, and a collar fixedly connected to the other end of each mounting seat, with the collars located outside the baffle respectively sleeved on the traction shaft;

[0006] A transmission disc is rotatably connected to the outer wall of the baffle, and several arrayed extrusion plates are fixedly connected to the outer side of the transmission disc. A hydraulic cylinder is movably installed at the upper end of the base plate, and the output end of the hydraulic cylinder is hinged to the outer wall of the transmission disc.

[0007] Preferably, the upper end of the base plate is provided with through slots, and each through slot is provided with a limiting pin.

[0008] Preferably, the upper end of the limiting pin is designed as a frustum, and a pull ring is fixedly connected to the upper end of the frustum, while the lower end of the limiting pin is designed as a cone.

[0009] Preferably, the guide groove is convex, and the guide block has a convex structure design.

[0010] Preferably, the extrusion plate is designed to be inclined, and the extrusion plate is arranged correspondingly to the traction shaft.

[0011] Compared with existing technologies, the advantages of this invention are as follows: A hydraulic cylinder drives the transmission disc to rotate, and an inclined pressing plate pushes the traction shaft to slide along the guide groove. This causes the collar fitted on the traction shaft to pull the traction rope, creating a uniform tension on the reinforcing cage and counteracting the lateral force generated by the concrete flow during pouring. This multi-directional traction and limiting structure can adjust the position of the reinforcing cage in real time, preventing it from shifting due to external disturbances, thus ensuring strict alignment between the reinforcing cage and the design center of the pile foundation. This effectively solves the problem of insufficient positioning accuracy of the reinforcing cage in traditional construction, improving the quality of pile foundation construction.

[0017] Please refer to Figures 1-3. This utility model provides the following technical solutions:

[0018] Example 1: A building pile foundation anti-deviation device includes a base plate 1, with guide grooves 2 arrayed on the upper end of the base plate 1, guide blocks 3 slidably connected in each guide groove 2, traction shafts 4 fixedly connected to the upper end of each guide block 3, a baffle 5 fixedly connected to the upper end of the base plate 1, and a plurality of arrayed limiting blocks 6 fixedly connected to the upper end of the baffle 5, with traction ropes 7 slidably connected to each limiting block 6, mounting seats 8 rotatably connected to both ends of the traction ropes 7, and collars 9 fixedly connected to the other end of each mounting seat 8, with the collars 9 located outside the baffle 5 respectively sleeved on the traction shafts 4;
