[0020] 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; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 2 The utility model provides a technical solution: a multi-angle positioning rod device applied to the steel column formwork back rib connection piece, the inner side wall of the steel frame 2 is fixedly connected to the steel column formwork panel 1, the inner side wall of the steel frame 2 is fixedly connected to the steel secondary rib 3, the outer wall of the steel secondary rib 3 is fixedly connected to the inner wall of the steel column formwork panel 1, the outer wall of the steel secondary rib 3 is welded with a multi-angle positioning rod device, and a steel back rib 4 connected to the multi-angle positioning rod device is provided on one side of the steel column formwork panel 1 and the steel frame 2;

[0022] The multi-angle positioning rod device includes a multi-angle positioning rod 6. A strip groove is opened through the outer wall of the steel back rib 4. One end of the multi-angle positioning rod 6 is inserted into the strip groove. The outer wall of the multi-angle positioning rod 6 is movably connected to the steel plate 5. The outer wall of the multi-angle positioning rod 6 and one side of the steel plate 5 are threadedly connected with a nut B.

[0023] One end of the multi-angle positioning rod 6 is provided with an external thread 7, and a bearing support 8 is welded to the outer wall of the steel secondary rib 3. A threaded bearing 13 is provided between the two bearing supports 8. The inner wall of the multi-angle positioning rod 6 is rotatably connected to the outer wall of the threaded bearing 13. The outer wall of the threaded bearing 13 and both sides of the multi-angle positioning rod 6 are provided with nuts A9, rubber gaskets 10, spring washers 11, and steel washers 12. Two steel washers 12 are provided on the left and right sides of the multi-angle positioning rod 6.

[0024] The outer walls of the two steel washers 12 abut against the outer wall of the multi-angle positioning rod 6, and spring washers 11 are arranged between the two steel washers 12 on the left and between the two steel washers 12 on the right. The outer walls on both sides of the rubber gasket 10 abut against the outer walls of the nut A9 and the steel washer 12 respectively, and the nut A9 is threadedly connected to the outer wall of the threaded bearing 13.

[0025] In this embodiment, the steel column formwork panel 1 is connected to the steel back rib 4 through the multi-angle positioning rod 6. The installer inserts the steel back rib 4 into the multi-angle positioning rod 6. After tightening the nut B, the steel back rib 4 can be fixed to the multi-angle positioning rod 6 and the steel back rib 4 can be adjusted to ensure the verticality of the column.

[0026] The multi-angle positioning rod 6 uses rubber gaskets 10 and spring washers 11 as damping adjusters. A certain pressure is first applied to both ends through nuts A9 until the multi-angle positioning rod 6 can be positioned at multiple angles. Then the two sides are fixed to the bearing support 8, and finally the bearing support 8 is welded to the steel secondary rib 3 of the steel column mold.

[0027] The outer wall of the nut B abuts against the outer wall of the steel plate 5 , and the outer wall of the steel plate 5 abuts against the outer wall of the steel back rib 4 .

[0028] In this embodiment, after tightening the nut B, the steel back rib 4 can be fixed to the multi-angle positioning rod 6, and the arrangement of the steel plate 5 makes the abutment and fixing effect better.

[0029] The width of the steel plate 5 is greater than the width of the strip groove.

[0030] In this embodiment, the width of the steel plate 5 is greater than the width of the strip groove, which facilitates the steel plate 5 to be limited and fixed on the outer side of the steel back rib 4.

[0031] The steel column formwork panels 1 are evenly distributed in a left-right array on the steel frame 2 , and the steel secondary ribs 3 are evenly distributed in a vertical array on the steel frame 2 .

[0032] In this embodiment, the provision of multiple steel column formwork panels 1 and steel secondary ribs 3 increases the stability of the device.

[0033] The steel back rib 4 can also be fixed by welding, which can also facilitate installation. However, this method has the following problems: firstly, the steel formwork will affect the lower structure when it is stacked, causing plastic deformation of the formwork; secondly, it is inconvenient to transport.

[0034] Working principle: The steel column formwork panel 1 is connected to the steel back rib 4 through the multi-angle positioning rod 6. The installer inserts the steel back rib 4 into the multi-angle positioning rod 6. After tightening the nut B, the steel back rib 4 can be fixed to the multi-angle positioning rod 6 and the steel back rib 4 can be adjusted to ensure the verticality of the column.

[0035] The multi-angle positioning rod 6 uses rubber gaskets 10 and spring washers 11 as damping adjusters. A certain pressure is first applied to both ends through nuts A9 until the multi-angle positioning rod 6 can be positioned at multiple angles. Then the two sides are fixed to the bearing support 8, and finally the bearing support 8 is welded to the steel secondary rib 3 of the steel column mold.

[0036] The invention solves the problem that the existing steel back rib 4 is hung on the steel secondary rib 3 by a pull rod with a barb, and then the steel back rib 4 is fixed by using a steel plate and a nut. During the installation and disassembly process, since the pull rod has no effective connection method with the steel secondary rib 3, it is necessary to manually position it by hand. When tightening or loosening the nut, otherwise the pull rod and the steel back rib 4 may easily fall off.

[0037] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
