DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-13 A high pier formwork construction with a built-in safety protection platform includes a hook 1 and a vertical steel bar 2. The bottoms of the two hooks 1 are fixedly installed on the tops of the two vertical steel bars 2 respectively. Multiple vertical steel bars 2 are distributed in a rectangular array in a vertical state. Horizontal steel bars 3 are fixedly installed on the surfaces of the multiple vertical steel bars 2. Multiple horizontal steel bars 3 are linearly arranged on the vertical surfaces of the vertical steel bars 2.

[0034] The plurality of vertical steel bars 2 and the plurality of horizontal steel bars 3 are combined into a cage body 4 , and the opposing surfaces of every two cage bodies 4 are provided with a quick docking adjustment mechanism 5 .

[0035] In order to realize the quick installation, docking or disassembly of the two cage bodies 4; the quick docking adjustment mechanism 5 includes a connecting rod 51 and a connecting seat 52 that is slidably connected to the connecting rod 51, the top of the connecting rod 51 is fixedly installed with the bottom of the upper vertical steel bar 2, and the bottom of the connecting seat 52 is fixedly installed with the top of the lower vertical steel bar 2.

[0036] Specifically, when two cage bodies 4 need to be docked, the plug-in rod 51 at the bottom of the top cage body 4 is controlled to be plugged into the plug-in seat 52 above the lower cage body 4, so that the docking can be quickly installed and realized, avoiding the use of welding in the existing docking, which makes it impossible to disassemble later and increases the cost and difficulty of later processing.

[0037] In order to achieve the limited locking during docking and form a firm and stable connection, a limited seat 53 is fixedly installed on the inner wall of the socket 52, and a plug-in limit groove 54 is provided on one side surface of the limited seat 53. Multiple plug-in limit grooves 54 are linearly arranged with vertical edges on the surface of the limited seat 53, and the surface of the limited seat 53 with the plug-in limit grooves 54 is slidably plugged into the opposite surface of the plug rod 51.

[0038] Specifically, when the plug-in rod 51 is plugged into the plug-in seat 52, one side surface is plugged into the limit seat 53, so that it corresponds to the plug-in limit groove 54, which is convenient for clamping into the plug-in limit groove 54 to form a stable installation effect.

[0039] In order to achieve the ability to adjust the height up and down as needed after the connection, a driving groove 55 is provided on the surface of the bottom end of the connecting rod 51 near the connecting limit groove 54, and a bearing seat 56 is fixedly installed on the inner top wall of the driving groove 55. The relative surfaces of the two bearing seats 56 are rotatably connected to the hinge shaft 57 through bearings, and a driving plate 58 is fixedly installed on the arc surface of the hinge shaft 57. The driving plate 58 swings with the axial direction of the hinge shaft 57 as the center.

[0040] Specifically, a driving plate 58 is provided inside the driving slot 55 of the plug-in rod 51. During installation, the driving plate 58 is clamped on the inner wall of the plug-in limit slot 54 to form a clamped and fixed whole. When adjustment is required, the driving plate 58 is controlled to leave the plug-in limit slot 54 and swing to tighten the inside of the driving slot 55, thereby enhancing adjustability and facilitating operation.

[0041] In order to enable the driving plate 58 to swing around the axial direction of the hinge shaft 57, a U-shaped seat 59 is fixedly installed on the surface of one side of the driving plate 58, and the relative inner walls of the U-shaped seat 59 are rotatably connected to the rotating shaft 510 through bearings. A connecting seat 511 is fixedly installed on the arc surface of the rotating shaft 510, and a pull rod 512 is fixedly installed on one end of the connecting seat 511. A spring 513 is movably sleeved on the arc surface of the pull rod 512, and one end of the spring 513 is in contact with the inner wall of the driving groove 55, and the other end of the spring 513 is in contact with the surface of the driving plate 58. The elastic force of the spring 513 pushes the driving plate 58 toward the inner wall of the plug-in limit groove 54 for extrusion.

[0042] Specifically, during the up and down movement adjustment of the sliding connection between the plug rod 51 and the inner wall of the plug seat 52, the pull rod 512 is pulled to drive the drive plate 58 to compress the extrusion spring 513, and then the drive plate 58 is swung to the inside of the drive groove 55 with the axis of the hinge shaft 57 as the center of the circle, and leaves the inside of the plug limit groove 54, thereby releasing the locking state to adjust the up and down position and disassemble.

[0043] In order to facilitate the operation of pulling the pull rod 512, a plug hole 514 is opened on the inner wall of one side of the driving groove 55, and the surface of one end of the pull rod 512 is slidably connected to the inner wall of the plug hole 514 in the axial direction. A sliding groove 515 is opened on the surface of one side of the socket 52, and one end of the pull rod 512 is threadedly connected to the handle 516. The inner wall of the sliding groove 515 and one end of the handle 516 are slidably connected in a direction perpendicular to the edge line of the sliding groove 515.

[0044] Specifically, a slide groove 515 is provided on the surface of the socket 52 , so that during operation, one end of the handle 516 is threadedly connected to one end of the pull rod 512 , and the pull rod 512 can be pulled to slide up and down on the inner wall of the slide groove 515 .

[0045] A flip mechanism 6 is provided on the top of each cage body 4 to enable workers to flip, open and pass through the interior of multiple cage bodies 4; the flip mechanism 6 includes a flip positioning seat 61 and a horizontal steel pipe 62, and the two flip positioning seats 61 are located at the middle horizontal line of the two hooks 1. The flip positioning seat 61 is fixedly installed on the top of the vertical steel bar 2 through a bearing, and the relative surfaces of the two flip positioning seats 61 are rotatably connected to the flip shaft 63 through a bearing.

[0046] Specifically, when a worker needs to move through each cage body 4, he or she can push the turning shaft 63 with the axial direction as the center of the circle to make it turn over, so as to facilitate movement.

[0047] In order to realize the flipping and pushing operation, the arc surface of the flipping shaft 63 is fixedly installed on the inner wall of one of the transverse steel tubes 62, and the surfaces of multiple transverse steel tubes 62 are fixedly installed with longitudinal steel tubes 64, and the multiple longitudinal steel tubes 64 are linearly arranged on the surface of the transverse steel tubes 62. The multiple transverse steel tubes 62 and the multiple longitudinal steel tubes 64 constitute a standing platform 65. The arc surfaces of the two transverse steel tubes 62 at both ends of the multiple longitudinal steel tubes 64 are rotatably connected with sleeves 66. Every four sleeves 66 are grouped into two sleeves 66, and the two groups of sleeves 66 are symmetrically mirrored.

[0048] Specifically, when the flip shaft 63 is controlled to rotate, the standing platform 65 composed of multiple horizontal steel pipes 62 and multiple longitudinal steel pipes 64 on the surface is flipped to make it perpendicular to the cage body 4, so that workers can pass through. In addition, the multiple horizontal steel pipes 62 and multiple longitudinal steel pipes 64 are connected by warp and weft to form the standing platform 65, which enhances its reliability for workers to stand and operate.

[0049] A connecting rod 67 is fixedly installed between the relative surfaces of every four sleeves 66, and a clamping plate 68 is fixedly installed on one side of the arc surface of each sleeve 66. One end of the clamping plate 68 is in an arc shape and contacts the surface of the horizontal steel bar 3. A plug-in positioning groove 69 is provided on the arc surface of the other end of each sleeve 66. A plug-in positioning plate 610 is slidably inserted into the inner wall of each four plug-in positioning grooves 69. The bottom of the plug-in positioning plate 610 contacts the surface of the horizontal steel pipe 62 and the surface of the longitudinal steel pipe 64 below. A positioning hole 611 is provided on one side surface of the plug-in positioning plate 610.

[0050] Specifically, when flipping is not required, the plug-in positioning plate 610 is plugged into the plug-in positioning groove 69 to control the four adjacent sleeves 66 to be connected into a whole, so that the plug-in positioning plate 610 is located at the top of the horizontal steel pipe 62 and the longitudinal steel pipe 64 for limiting, thereby avoiding the danger of falling when standing on the standing platform 65. The clamping plates 68 at both ends are clamped to the surface of the horizontal steel bar 3, so that the clamping plates 68 at both ends of the standing platform 65 are simultaneously clamped to form a limiting support to assist standing. When disassembly is required, the plug-in positioning plate 610 is pulled out, and the multiple sleeves 66 are controlled to separate as a whole. When flipping the standing platform 65, the setting of the rotational connection between the sleeve 66 and the horizontal steel pipe 62 is used to rotate the sleeve 66 so that the clamping plate 68 is no longer clamped to the surface of the horizontal steel bar 3, and contacts the limiting support to achieve the effect of flipping.

[0051] A threaded hole 612 is provided on the arc surface of the sleeve 66, and a steel ball 613 is slidably inserted into the inner wall of one end of the threaded hole 612. The inner wall of one end of the threaded hole 612 is fixedly connected to the inner wall of the insertion positioning groove 69, and the diameter of the inner wall of one end of the threaded hole 612 is smaller than the diameter of the steel ball 613. The arc surface of the steel ball 613 is slidably inserted into the inner wall of the positioning hole 611. The inner wall of the threaded hole 612 is also movably sleeved with a compression spring 614, one end of the compression spring 614 is in contact with the surface of the steel ball 613, and the inner wall of the threaded hole 612 is threadedly connected with a plug 615, and one side surface of the plug 615 is in contact with the opposite end of the compression spring 614.

[0052] Specifically, when the plug-in positioning plate 610 is plugged into the inner wall of the sleeve 66, the plug 615 installed inside the sleeve 66 is used to squeeze the compression spring 614 to generate pressure to push the steel ball 613 to be squeezed into the internal positioning hole 611 for positioning, thereby preventing the plug-in positioning plate 610 from moving and falling during installation and causing personal injury. The setting that the inner wall diameter of one end of the threaded hole 612 is smaller than the diameter of the steel ball 613 prevents the steel ball 613 from leaving the inside of the threaded hole 612 under the pressure of the compression spring 614, resulting in the effect that the plug-in positioning plate 610 cannot be positioned and squeezed.

[0053] To reduce construction risks during formwork installation and ensure the safety of workers, the present invention features a formwork cage 4 that serves as both a walkway and operating platform, effectively reducing safety risks and improving operational efficiency. A reversible platform 65 is installed within the cage 4, formed by connecting transverse and longitudinal steel pipes 62 and 64. Workers can stand on the platform to install formwork bolts. Once bolt installation is complete, the platform can be flipped up and down through the cage 4 to continue bolting the next layer of formwork. The cage 4 is directly suspended from the formwork at the top of the high pier via a hook 1, ensuring convenient, safe, and reliable operation.

[0054] Working principle: During operation, first take the lowest cage body 4 and install it on the ground, then use the lifting equipment to control the second cage body 4 to be placed above the first cage body 4, control the plug-in rod 51 to be plugged into the top of the plug-in seat 52, control its pull rod 512 to come to the bottom of the slide groove 515, and the drive plate 58 is plugged into the inside of the first plug-in limit groove 54. When continuing to move downward, use the handle 516 to be threadedly connected to one end of the pull rod 512, thereby pulling the pull rod 512 to move to one side of the drive groove 55, and then control the drive plate 58 to leave the plug-in limit groove 54, so as to facilitate the plug-in rod 51 to continue to move downward, and then make its four plug-in rods 51 installed inside the plug-in seat 52. When the pull rod 512 threadedly connected to the handle 516 is released, the drive plate 58 is controlled to be plugged into the inside of the plug-in limit groove 54 under the action of the spring 513 for limited and fixed installation.

[0055] Similarly, after the second cage 4 is installed, the subsequent cages 4 are installed until the installation of the top cage 4 is completed. The control hook 1 is hung on the formwork of the high pier column, and the staff can stand inside the cage 4 to install the formwork on the surface of the high pier column. When it is necessary to move upward, pull out the plug-in positioning plate 610 and push the standing platform 65 at the top upward to make it flip over, so that the staff can climb up. After climbing up, the control clamping plate 68 is clamped on the surface of the horizontal steel bar 3, and the positioning plate 610 is continued to be plugged in to limit and lock its sleeve 66, so as to facilitate the staff to stand and install the formwork.

[0056] When the template needs to be dismantled after installation, it can be dismantled in the same way and the next high pier operation can be carried out.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
