Description

Technical Field

[0001] The utility model relates to the technical field of steel cages, in particular to a steel cage suspension bar connection structure for full-casing pipe bite piles. Background Art

[0002] During the construction of bridges, culverts or high-rise buildings, in order to ensure the stability of the building, it is usually necessary to pour a very deep foundation. The method used is to drill a hole in the ground first, and then pour it when the hole depth reaches the design requirements. In order to improve the tensile strength of concrete, a cylindrical steel bar support made of main bars and coil bars welded together needs to be placed in the hole first. This steel bar support is often called a steel cage.

[0003] The traditional rebar cage lifting device uses a simple hook to hook the surrounding steel bars at one end of the rebar cage, lifts the rebar cage vertically and places it into the hole, and completes the docking and fixing effect after mechanical connection through the rebar sleeve. However, since the entire rebar cage is heavy, the rebar sleeve alone cannot bear the weight. The rebar sleeve has the defects of low efficiency in screwing the rebar into the sleeve and low connection quality, which makes it easy for the rebar cage to loosen. Utility Model Content

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] Example

[0022] like Figure 1-3 As shown, a steel cage suspension bar connection structure for full-casing bite piles includes multiple main bars 1, multiple support bars 2 are arranged on the inner side of the main bars 1, the main bars 1 and the support bars 2 are connected by a reinforcing hoop 3, threaded sleeves 4 and suspension bar assemblies 5 are respectively arranged at the upper and lower ends of the main bars 1, and the suspension bar assembly 5 is connected to the main bars 1 by a fixing piece 8.

[0023] A plurality of main bars 1 and support bars 2 are equidistantly arranged on both sides of the inner and outer sides of the reinforcing hoop 3. The height of the main bars 1 is greater than that of the support bars 2 and the reinforcing hoop 3. The reinforcing hoop 3 is spiral-shaped, and the reinforcing hoop 3, the main bars 1 and the support bars 2 are welded to each other. The reinforcing hoop 3 is placed between the main bars 1 and the support bars 2 and fixed to each other by welding. The support bars 2 are welded to the inside of the steel cage and are arranged equidistantly with the reinforcing hoop 3 as the center of the circle, so as to support and reinforce the overall structure of the steel cage.

[0024] The upper and lower ends of the main reinforcement 1 are respectively provided with an upper external thread 6 and a lower external thread 7, and the threaded sleeve 4 and the hanger assembly 5 are respectively threadedly connected with the upper external thread 6 and the lower external thread 7. When the two reinforcement cages are butt-jointed up and down, the threaded sleeve 4 is used to lock the upper external thread 6 and the lower external thread 7 with each other to achieve butt-jointing.

[0025] The suspension bar assembly 5 includes a positioning nut 51 and a connecting bar 52. The positioning nut 51 is threadedly connected to the lower external thread 7. The connecting bar 52 is L-shaped. The connecting bar 52 includes a telescopic part 521 and a suspension part 522. A limiting part 523 is provided at the upper end of the telescopic part 521. The telescopic part 521 has a threaded end and a smooth end. The telescopic part 521 is connected to the positioning nut 51 through the threaded end. The suspension bar assembly 5 is placed at the lower end of the main bar 1. After the two steel cages are connected to each other, the connecting bar 52 on the suspension bar assembly 5 is rotated, and one L-shaped end is rotated to the outside of the steel cage and inserted into the reinforcing hoop 3 of the lower end steel cage, which plays a role of suspension auxiliary support to prevent the two steel cages from loosening.

[0026] When in use, the steel cage at the upper end is suspended by the lifting device and docked with the steel cage at the lower end. The pre-docking is completed by the lifting device, and then the threaded sleeve 4 on the main reinforcement 1 of the lower reinforcement cage is screwed upward along the upper external thread 6 until the threaded sleeve 4 is screwed onto the lower external thread 7 of the main reinforcement 1 of the upper reinforcement cage, so that the main reinforcement 1 of the upper and lower reinforcement cages is completed with the upper and lower docking, and is locked and fixed by the threaded sleeve 4. Finally, the hanging bar assembly 5 on the upper reinforcement cage is adjusted, and the connecting bar 52 on the hanging bar assembly 5 is rotated, one end of the L-shape is rotated to the outside of the reinforcement cage, and inserted into the reinforcing hoop 3 of the lower reinforcement cage, which plays the role of suspension auxiliary support to prevent the two reinforcement cages from loosening.
