[0018] The present utility model will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment 1

[0020] Combined with Figures 1 to 3 As shown, this embodiment provides a fixing frame for the lengthening and protection of the steel cage of a cast-in-place pile, including a main frame and a sub-frame. The main frame is composed of two main crossbars 11, a main vertical bar 13 and two main struts 12. The two main crossbars 11 are transversely welded and fixed between the two main struts 12, and the main vertical bar 13 is welded and fixed between the two main crossbars 11. The sub-frame is between two sub-crossbars 21 and two sub-vertical bars 22. The two sub-vertical bars 22 are vertically welded and fixed between the two sub-crossbars 21. Two sub-frames are installed between the two main frames, and a disassembly and assembly structure is provided between the sub-crossbar 21 and the main crossbar 11;

[0021] The disassembly and assembly structure includes a rectangular seat block 31, a connecting plug block 32, a rectangular sliding seat 33 and a limiting through rod 34. The rectangular seat block 31 and the connecting plug block 32 are welded and fixed. The connecting plug block 32 penetrates through the sub-crossbar 21 and the main crossbar 11 at the same time, and the rectangular seat block 31 is attached to the surface of the sub-crossbar 21. After penetration, the connecting plug block 32 can plug the sub-crossbar 21 and the main crossbar 11 together. The rectangular sliding seat 33 is slidably installed on the surface of the main crossbar 11. A limiting through rod 34 is welded and fixed to one side of the rectangular sliding seat 33. A through hole 321 corresponding to the limiting through rod 34 is formed in the end surface of the connecting plug block 32. The limiting through rod 34 penetrates through the end of the connecting plug block 32 through the through hole 321. After penetration, the limiting through rod 34 can play a role in stably limiting the connecting plug block 32, completing the assembly of the main crossbar 11 and the sub-crossbar 21. The disassembly and assembly structure further includes an inner slider 35, a spring 36, an annular support seat 37 and a connecting slider 38. The inner slider 35 is slidably arranged inside the main crossbar 11. The annular support seat 37 is fixed to the inner wall of the main crossbar 11. The spring 36 is arranged between the inner slider 35 and the annular support seat 37. A connecting slider 38 is fixed to one side surface of the inner slider 35. A connecting slideway 39 corresponding to the connecting slider 38 is formed on the surface of the main crossbar 11. The end of the connecting slider 38 extends to the outside of the main crossbar 11 and is fixed to the rectangular sliding seat 33. Under the pushing action of the spring 36, the limiting through rod 34 can always penetrate the connecting plug block 32 during daily use, and will not shift laterally and separate from the connecting plug block 32, thus ensuring the installation stability of the connecting plug block 32 and the connection stability between the sub-crossbar 21 and the main crossbar 11.

[0022] Compared with the prior art, the utility model improves and optimizes the lengthening protection fixing frame of the cast-in-place pile steel reinforcement cage in the prior art, and designs a disassembly and assembly structure composed of a rectangular seat block, a connecting plug block, a rectangular sliding seat, a limiting through rod and other structures between the mother frame and the son frame, which can realize the rapid assembly and disassembly between the mother frame and the son frame, so as to facilitate the rapid disassembly and assembly of the fixing frame by the operator at the construction site of the cast-in-place pile steel reinforcement cage, and greatly improve the use convenience of the whole fixing frame.

[0023] One end of the spring 36 abuts against the annular support seat 37, and the other end of the spring 36 abuts against the inner slider 35.

[0024] One end of the auxiliary cross bar 21 is provided with a jack B211 corresponding to the connecting plug block 32 for the connecting plug block 32 to penetrate through the auxiliary cross bar 21 smoothly, and the surface of the main cross bar 11 is provided with a jack A111 corresponding to the connecting plug block 32 for the connecting plug block 32 to penetrate through the main cross bar 11 smoothly.

[0025] In summary, when it is necessary to assemble the fixing frame at the construction site of the cast-in-place pile steel reinforcement cage, first place the son frame between two mother frames, make the auxiliary cross bar 21 can be placed on the surface of the main cross bar 11, and make the jack B211 and the jack A111 aligned. Then pull the rectangular sliding seat 33 to the side, make the connecting slider 38 move to the side with the connecting slider 38, and compress the spring 36, causing the limiting through rod 34 to move to one side of the jack A111. At this time, the operator can pass the connecting plug block 32 through the jack B211 of the auxiliary cross bar 21, and make the connecting plug block 32 pass through the jack A111 of the main cross bar 11 until the rectangular seat block 31 fits with the auxiliary cross bar 21. At this time, the through hole 321 will be aligned with the limiting through rod 34. The operator only needs to release the rectangular sliding seat 33, the spring 36 will push the inner slider 35 back, and make the connecting slider 38 drive the rectangular sliding seat 33 to rebound and reset, and finally make the limiting through rod 34 penetrate through the end of the connecting plug block 32, so as to quickly connect the auxiliary cross bar 21 and the main cross bar 11 together, realize the rapid assembly between the mother frame and the son frame, greatly improve the assembly convenience of the whole fixing frame, and also facilitate the subsequent disassembly of the fixing frame.

[0026] Embodiment 2

[0027] Combined with Figures 1 to 4 As shown in the figure, on the basis of Embodiment 1, this embodiment plays an auxiliary positioning role when the connecting plug block 32 penetrates through the auxiliary cross bar 21 and the main cross bar 11 through the set auxiliary structure.

[0028] Specifically, the disassembly and assembly structure further includes an auxiliary structure, which is arranged between the connecting plug 32 and the secondary cross bar 21. The auxiliary structure includes a rubber inner seat 212, a positioning protrusion 213, and an annular slot 322. Two rubber inner seats 212 are fixed to the inner wall of the secondary cross bar 21 at the jack B211. The surface of the rubber inner seat 212 is provided with a positioning protrusion 213. An annular slot 322 corresponding to the positioning protrusion 213 is formed on the surface of the connecting plug 32. The end of the positioning protrusion 213 is squeezed into the annular slot 322, which can play an auxiliary positioning effect when the connecting plug 32 penetrates the secondary cross bar 21 and the main cross bar 11, preventing the connecting plug 32 from falling off when it is not penetrated by the limiting rod 34, and further facilitating the subsequent assembly of the secondary cross bar 21 and the main cross bar 11.

[0029] Among them, the rubber inner seat 212 and the positioning protrusion 213 are of an integral structure, and both are made of rubber material. An oval cavity is also formed in the rubber inner seat 212, so that the positioning protrusion 213 has enough deformation space when being squeezed.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, or improvements made within the technical scope of the present invention shall be included within the scope protected by the present invention.
