[0020] The present application will be further described below in conjunction with specific embodiments. Among them, the drawings are only used for illustrative description, and the representation is only a schematic diagram, not a physical diagram, and cannot be understood as a limitation of the present patent; in order to better illustrate the embodiments of the present application, some components in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it can be understood that some known structures and their descriptions in the drawings can be omitted. The drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0021] In addition, the present application can refer to the same reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0022] As Figs. 1-2As shown, the utility model relates to a detachable template positioning pull rod, wherein: including positioning pull rod 1, two positioners 2 of fixed in the outer wall of positioning pull rod 1, the distance between the two positioners 2 is equal to wall body design thickness, the trapezoidal card 3 of screw connection in the end position of positioning pull rod 1,

[0023] Positioning pull rod 1 is screw connected on template 4, template 4 is provided with threaded hole 5 and let hole 6, let hole 6 is through with threaded hole 5, and the appearance of let hole 6 is mutually matched with the appearance of positioner 2,

[0024] Positioning pull rod 1 is equipped with PVC protection pipe 8, and the positioner 2 is located in the PVC protection pipe 8, and the outer plate surface of the positioner 2 is flush with the outer end surface of the PVC protection pipe 8.

[0025] When using, the outer plate surface of the positioner 2 is tightly attached to the inner plate surface of the template 4, and the inner plate surface of the trapezoidal card 3 is tightly attached to the outer plate surface of the template 4. In this embodiment, the positioning pull rod 1 adopts a threaded rod, and the size of the positioner 2 is slightly smaller than the size of the let hole 6.

[0026] To further reduce the manufacturing cost, in the above embodiment, preferably: the positioner 2 is a plate body. In this embodiment, the plate body is a block made of steel material.

[0027] To facilitate the disassembly of the positioning pull rod 1, in the above embodiment, preferably: the end of the positioning pull rod 1 is provided with a flat operating part 7 which is integral with it.

[0028] In the above embodiment, all components are market sales products.

[0029] The use process of the structure in the above scheme is: when reinforcing the template 4 of the culvert wall body, the positioner 2 is rotated to position the pull rod 1 by passing through the let hole 6, the end of the positioning pull rod 1 is inserted into the threaded hole 5 on the template 4 and is screw connected with it, so that the outer plate surfaces of the two positioners 2 are tightly attached to the inner plate surfaces of the two templates 4 respectively, the thickness of the culvert wall body is controlled, the template is fixed, then the trapezoidal card 2 is rotated to be screw fixed with the positioning pull rod 1, until the inner plate surface of the trapezoidal card 2 is tightly attached to the outer plate surface of the template 4, the reinforcement of the template 4 can be realized. Then the concrete is poured, and in the pouring process, the PVC protection pipe 8 protects the positioner 2 and the positioning pull rod 1, so that the positioner 2 and the positioning pull rod 1 are isolated from the concrete. When disassembling, the trapezoidal card 2 is reversely rotated to be removed, then the positioning pull rod 1 is rotated by clamping the flat operating part 7 with a wrench, so that the positioner 2 is directed to be consistent with the let hole 6, the positioner 2 and the positioning pull rod 1 can be taken out. The whole process can realize the reinforcement of the template 4 and the positioning of the wall body thickness at the same time, the taken-out positioner 2 and positioning pull rod 1 can be reused; the wall body thickness positioning is no longer needed, the construction efficiency is improved and the construction cost is reduced.
