[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Reference Figure 1-4 , a combined pier steel formwork, comprising a first formwork 1 and a second formwork 2;

[0025] A second template 2 is detachably mounted on one side of the first template 1, and the first template 1 and the second template 2 are symmetrically mounted. A plug 5 is fixedly welded to the outer wall of one side of the first template 1 and the second template 2, and an insert block 9 is integrally formed at the front end of the plug 5. A socket 6 is fixedly welded to the outer wall of the other side of the first template 1 and the second template 2, and a socket 11 is penetrated through the rear side of the socket 6.

[0026] There are three groups of plugs 5 and sockets 6, which are evenly distributed on the outer walls of both sides of the first template 1 and the second template 2, and each group of plugs 5 corresponds to each group of sockets 6;

[0027] Secondly, the first template 1 and the second template 2 are fixedly installed by the plug 5 and the socket 6, and the first template 1 and the second template 2 can be assembled and assembled into a columnar pier body steel template as a whole, and after the assembly is completed, the first template 1 and the second template 2 can be placed inside the columnar pier body steel template as a whole for pouring;

[0028] Specifically, the plug block 9 is inserted into the socket 11, and a mounting screw hole 12 is formed through the front end of the socket 6. A bolt 14 is threadedly connected to the mounting screw hole 12, and the bolt 14 can rotate and move in the mounting screw hole 12. A fixing screw hole 10 is formed in the center of the front end of the plug block 9. The bolt 14 is located in the mounting screw hole 12 and can rotate and move backward. The other end of the bolt 14 can be screwed into the fixing screw hole 10 by continuing to rotate, thereby realizing the fastening work after the plug block 9 is inserted into the socket 11;

[0029] In addition, the outer walls of the first formwork 1 and the second formwork 2 are welded with a number of annular keel strips for anti-deformation. The design of the keel strips can effectively improve the strength of the formwork, prevent deformation, and ensure the quality of the pier casting;

[0030] It is worth mentioning that positioning balls 13 are integrally formed at both ends of the first template 1, and positioning ball grooves 15 are opened at both ends of the second template 2, and the sizes of the positioning balls 13 and the positioning ball grooves 15 correspond to each other;

[0031] The number of the positioning balls 13 and the positioning ball grooves 15 are both six groups, and the six groups of positioning balls 13 and the six groups of positioning ball grooves 15 correspond to each other. The positioning balls 13 can be embedded in the positioning ball grooves 15. When the first template 1 and the second template 2 are assembled, the positioning balls 13 can be embedded in the positioning ball grooves 15 to complete the positioning work of the first template 1 and the second template 2 during installation, which can effectively prevent the first template 1 and the second template 2 from being misaligned.

[0032] In this embodiment, the first template 1 and the second template 2 can be assembled symmetrically, and when combined, the positioning ball 13 can be inserted into the positioning ball groove 15 to ensure the alignment of the two sets of templates. At the same time, the plug block 9 can be inserted into the socket 11, and then the bolt 14 inside the mounting screw hole 12 can be rotated clockwise. At this time, the bolt 14 can move toward the side of the plug block 9. After the bolt 14 is inserted into the fixing screw hole 10, it can be screwed on by continuing to rotate. As the bolt 14 continues to go deeper, the connection strength between the first template 1 and the second template 2 gradually increases. After the installation is completed, the pier body template assembly can be formed.

[0033] Reference Figure 1-2, the first template 1 and the second template 2 are both integrally formed with an annular mounting block 3 on the top, and the two groups of annular mounting blocks 3 are butted together to form an integral annular convex block after the first template 1 and the second template 2 are combined, and an annular mounting groove 7 is provided on the bottom of the first template 1 and the second template 2, and the two groups of annular mounting grooves 7 are butted together to form an integral annular groove after the first template 1 and the second template 2 are combined, and the annular mounting block 3 and the annular mounting groove 7 correspond to each other;

[0034] Among them, the outer wall of the annular mounting block 3 is provided with an external thread 4, and the inner wall of the annular mounting groove 7 is correspondingly provided with an internal thread 8, the annular mounting block 3 can be screwed into the annular mounting groove 7, and the external thread 4 and the internal thread 8 are meshed with each other, and the screwing and fixing work of the annular mounting block 3 in the annular mounting groove 7 can be realized by the meshing of the external thread 4 and the internal thread 8;

[0035] In this embodiment, multiple groups of first templates 1 and second templates 2 are prepared to be combined into multiple groups of complete templates, and then the multiple groups of installed templates can be stacked and installed. During installation, it is only necessary to screw the top annular mounting block 3 into the annular mounting groove 7 at the bottom of another group of templates. The splicing can be completed without using bolts and nuts, and the installation height can be determined according to the number of template groups installed.

[0036] Working principle: First, the first template 1 and the second template 2 can be assembled. During assembly, the positioning ball 13 on the first template 1 can first be embedded in the positioning ball groove 15 on the second template 2 to complete the positioning and alignment. At this time, the plug block 9 can be inserted into the socket 11, and then the bolt 14 in the mounting screw hole 12 is rotated to screw it into the fixing screw hole 10. After tightening, the assembly of the first template 1 and the second template 2 can be completed, and the assembly is firm and reliable. Subsequently, the appropriate number of template components can be selected and assembled according to the required pier height, and then several groups of assembled template components can be stacked upward in sequence. During stacking, the annular mounting block 3 with an external thread 4 can be screwed into the annular mounting groove 7 with an internal thread 8, so that multiple groups of template components can be screwed and fixed. When the template needs to be disassembled, just rotate the bolt 14 counterclockwise to screw it out of the fixing screw hole 10, and then separate the first template 1 and the second template 2.
