Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a pile foundation reinforcement cage auxiliary docking device and a use method thereof. Background Art

[0002] The main function of the steel cage is similar to the load-bearing effect of the longitudinal reinforcement of the column, mainly to resist tension. Concrete has high compressive strength but very low tensile strength. It restrains the pile concrete, allowing it to withstand a certain amount of axial tension. During the construction of bridges, culverts, or high-rise buildings, the foundation may be required to be piled according to the requirements. This is done by using a machine punch or water drill to ensure the hole depth meets the design requirements. The steel cage is then lowered into the pile hole, and a guide tube is inserted to pour concrete.

[0003] Currently, the steel reinforcement connections for bridge pile foundations in highway projects are typically made using a crane. The cage is lowered to the designated location, and then the main bars of the cage are manually connected. However, due to the heavy weight of the cage, the cage will swing due to inertia during the crane's installation. This can easily lead to slight deviations in the steel sleeves of the cage's main bars, making it difficult to precisely connect the cages. This requires manual adjustments using both machinery and labor, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The embodiment of the present invention provides a pile foundation steel cage auxiliary docking device and a method of using the same, which can achieve rapid docking of the main reinforcement of the pile foundation steel cage compared with traditional methods, reduce manpower input and labor intensity, and shorten the docking and installation time of the pile foundation steel cage.

[0005] In view of the above problems, the technical solution proposed by the present invention is:

[0006] The top end of the docking rod and the bottom end of the docking sleeve are connected to each other, and an observation port is provided on the outside of the docking sleeve.

[0007] As a preferred technical solution of the present invention, an auxiliary block is installed at the bottom of the docking rod, the auxiliary block is truncated cone-shaped, and a second docking groove is opened on the outside of the auxiliary block, the first docking groove and the second docking groove are connected to each other, and the depth and width of the first docking groove and the second docking groove are consistent.

[0008] As a preferred technical solution of the present invention, an alignment block is installed on the top end of the docking rod, and the alignment block can slide in the connecting groove.

[0009] As a preferred technical solution of the present invention, the interior of the connecting sleeve is slidably connected to a butt plate, one side of the butt plate is provided with a groove, and the groove can slide on the outside of the docking plate, and a second spring is connected between the butt plate and the connecting sleeve.

[0010] As a preferred technical solution of the present invention, a pair of the fixing mechanisms each include a fixed block, which is respectively connected to the top end of the docking rod and the bottom end of the docking sleeve. A fixed plate and a movable plate are installed on one side of the fixed block, and a semi-clamping sleeve is installed on the side close to each other.

[0011] As a preferred technical solution of the present invention, a pair of grooves are opened on one side of the fixed block, and the inside of the pair of grooves are connected to the rotating shaft through torsion springs, a pair of connecting plates are installed on one side of the movable plate, and the connecting plates are installed on the outside of the rotating shaft, and the inner walls of the semi-ferrules are installed with anti-slip pads.

[0012] As a preferred technical solution of the present invention, the locking mechanism includes a locking plate, threaded holes are provided on one side of the locking plate and the fixed block, a threaded rod is engaged between the threaded holes, a knob is installed at one end of the threaded rod, a limiting groove is provided on one side of the fixed block, a limiting block is installed on one side of the locking plate, and the limiting block and the limiting groove can be engaged with each other.

[0013] As a preferred technical solution of the present invention, the thickness of the docking plate is smaller than the thickness of the alignment block, and the width of the first docking groove is smaller than the width of the connecting hole.

[0014] As a preferred technical solution of the present invention, a buffer pad is installed on the top of the docking sleeve.

[0015] In another aspect, the present invention provides a method for auxiliary docking of a pile foundation reinforcement cage, comprising the following steps:

[0016] S1, device installation: fix a pair of fixing mechanisms and a pair of vertical reinforcement bars of the reinforcement cage, wherein the fixing mechanism connected to the bottom end of the docking sleeve is fixed to the installed reinforcement cage, and the fixing mechanism at the top end of the docking rod is fixed to the reinforcement cage to be installed. The specific fixing method is to bring the pair of half-clamping sleeves closer together and place the vertical reinforcement bars of the reinforcement cage inside the pair of half-clamping sleeves, then engage the limit block with the limit groove, and use the threaded rod to fix the locking plate and the fixing block;

[0017] S2, docking: When the crane lifts the steel cage to be installed and moves the steel cage to be installed above the installed steel cage, the steel cage to be installed can be lowered so that the docking rod slides into the docking sleeve. As the steel cage to be installed moves downward, the docking rod slides into the connecting sleeve.

When the crane lifts the steel cage to be installed and moves the steel cage to be installed above the installed steel cage, the docking rod slides into the docking sleeve. As the steel cage to be installed moves downward, the docking rod will slide into the connecting sleeve. If the two steel cages are not completely aligned , then, the docking plate will be squeezed by the docking rod and move backward, and the user can observe this situation through the observation port. At this time, the user can fine-tune the steel cage to be installed, so that the first docking groove moves to the position of the docking plate, thereby ensuring that a pair of fixing mechanisms are aligned with each other, and then ensuring that the two steel cages can be aligned. At this time, under the action of the first spring, the docking plate and the first docking groove engage with each other, thereby ensuring that the two steel cages will no longer have relative displacement. Compared with the traditional method, this technical solution can realize the rapid docking of the main bars of the pile foundation steel cage, reduce personnel input and labor intensity, and shorten the docking and installation time of the pile foundation steel cage.

[0020] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.
