Problems solved by technology
When the load box is buried in the pile body, the reinforcement cage connected with the load box is disconnected, and the force transmission of the pile is carried out through the load box. The disconnected reinforcement cage seriously affects the effective downward transmission of the upper load box, however , the current load box cylinder and piston are not restrained when they are pulled out in the vertical direction, so the load box lacks the anti-pull function

Embodiment Construction
[0026] It should be noted that in this embodiment, the orientation words "up", "down", "top" and "bottom" are all described according to the drawings and do not constitute a limitation to the present invention.
[0027] Attached below Figure 1-9 The present invention is further described in detail: a rigid connector connected to the upper and lower reinforcement cages of the load box, such as figure 1 As shown, the rigid connector includes a sleeve 1 with shear resistance, an upper metal rod 2 and a lower metal rod 3; as figure 2 As shown, the bottom of the upper metal rod 2 is fixed to the top of the sleeve 1 with shear resistance. Sleeve 1 with shear performance; the sleeve 1 with shear resistance is a cavity with an opening at the bottom, and a groove is opened on the top, the inner diameter of the groove is adapted to the outer diameter of the bottom of the upper metal rod 2, and the bottom opening surrounds the belt The center of the sleeve 1 with shear resistance is ...

The invention relates to a connecting part for an upper reinforcement cage and a lower reinforcement cage of a load box, in particular to a rigid connecting part capable of enhancing the crush resistance and the pull resistance of a load box, and belongs to the field of architectural engineering. The rigid connecting part connected to the upper reinforcement cage and the lower reinforcement cage of the load box comprises an upper metal rod, a lower metal rod and a sleeve. One end of the upper metal rod is fixedly connected with an upper plate of the load box, and the other end of the upper metal rod is fixedly connected with the top of the sleeve. One end of the lower metal rod is fixedly connected with a lower plate of the load box, and the other end of the lower metal rod stretches intothe sleeve. The sleeve is a cavity with an opening in the bottom. The lower metal rod can move downwards along with the load box under the action of external force. The rigid connecting part has the advantages that 1, the vertical anti-pressure ability of a detected pile is improved; and 2, the anti-pull ability of the detected pile is improved.
Description
technical field [0001] The invention relates to a connecting piece used for the upper and lower reinforcement cages of a load box, in particular to a rigid connecting piece capable of enhancing the compression resistance and pullout resistance of the load box, and belongs to the field of construction engineering. Background technique [0002] When the current self-balancing load box works, the load box is buried at the bottom of the cast-in-place pile or at the calculated pile body position as a part of the engineering pile. When the load box is buried in the pile body, the reinforcement cage connected with the load box is disconnected, and the force transmission of the pile is carried out through the load box. The disconnected reinforcement cage seriously affects the effective downward transmission of the upper load box, however , the current load box cylinder and piston are not restrained when they are pulled out in the vertical direction, so the load box lacks the anti-pu...
