Description
Technical Field
[0001] The utility model relates to the technical field of concrete construction, and more specifically to a concrete cast-in-place pile connecting device. Background Art
[0002] Concrete piles, also known as cement fly ash gravel piles, are a commonly used foundation treatment method. They use cement, fly ash, gravel and water mixed in a certain proportion to form high-bonding strength piles, which together with the soil between piles and the cushion layer form a composite foundation. Concrete piles have the advantages of simple construction, low cost, large increase in bearing capacity, small post-construction deformation, and rapid settlement stability. They are suitable for a variety of soil conditions, including clay, silt, sand, etc.
[0003] A CFG pile connecting device is disclosed in a Chinese patent with the announcement number CN217500190U. In view of the problems that the existing technology of pile-joining formwork is cumbersome to assemble, the pile-joining formwork will be displaced during the concrete pouring process, resulting in the center of the pile connection not coinciding with the center of the CFG pile, and the iron drum is light in weight and easily floats, causing the bottom concrete to flow out. A CFG pile connecting device is provided, comprising a left semi-cylinder and a right semi-cylinder symmetrically arranged above the CFG pile, wherein the left semi-cylinder and the right semi-cylinder are hinged at one end by a hinge mechanism, and the other ends are connected by a locking mechanism. The pile connecting device of the utility model can be used cyclically and is durable, simple to assemble, easy to use, can be accurately positioned without displacement, and is not easy to float and cause leakage when pouring concrete.
[0004] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: the conventional recommended range of concrete piles is 350-600 mm, and there are various sizes and specifications. However, during use, this patent uses a ring, connecting bolts and connecting nuts to fix the left half cylinder and the right half cylinder together. It can only be used for piles of a specific diameter. Different pile connecting devices are required for piles of different diameters. When there are no piles of suitable diameters on site, it is necessary to wait for the appropriate pile connecting device to arrive at the site, thereby delaying the construction progress. In addition, pile connecting devices of various sizes need to be stored and managed, which increases the complexity of storage and logistics. Utility Model Content

This device can adapt to concrete piles of various sizes, reducing the difficulty and requirements of storage and logistics.
[0016] The left and right formworks are surrounded by the enclosing plate, and the two rings are locked together by the mounting plate, mounting seat, threaded rod and nut, thereby fixing the left and right formworks to avoid leakage of slurry at the overlapping parts of the left and right formworks when pouring concrete.
[0017] The position of the shielding cover can be changed by moving the component, and then the shielding cover can be moved directly above the nut. The angle of the shielding cover can be changed by adjusting the component, and then the shielding cover can be rotated to provide shielding for the nut from above, preventing concrete from falling on the nut during pouring, which would affect the subsequent disassembly work.
