[0022] The utility model embodiment provides a reinforced concrete guardrail shaping template, such as Figure 1-5 As shown, the mold is composed of an outer template 1 and an inner template 2. A protrusion 11 is welded on the top of the outer template 1, a rectangular block 21 is welded on the top of the inner template 2, and steel bars 22 are welded symmetrically on the top of the inner template 2 and on both sides of the rectangular block 21. The upper ends of the steel bars 22 are bent and extended above the outer template 1. A short screw 3 is welded on the top of the protrusion 11, and the short screw 3 is vertically upward between the two steel bars 22.

[0023] A pressing plate 4 is arranged above the outer formwork 1, the inner formwork 2 passes through the pressing plate 4 and is threadedly connected with a nut 31, and the end of the pressing plate 4 is placed on the steel bar 22. Through the nut 31, the pressing plate 4 is lowered, and the pressing plate 4 presses the steel bar 22, so that the upper end of the inner formwork 2 is flush with the upper end of the outer formwork 1.

[0024] The protrusion 11 is aligned with the rectangular block 21 , and a long screw 5 is connected between the protrusion 11 and the rectangular block 21 .

[0025] It also includes a tie rod 6, which passes through the outer template 1 and the inner template 2. The long screw 5 and the tie rod 6 cooperate to limit the two templates, thereby preventing the mold from deforming when the concrete slurry is poured into the mold.

[0026] The protrusion 11 is provided with a through slot 12, the rectangular block 21 is provided with a hole 211, one end of the long screw rod 5 passes through the hole 211, the other end of the long screw rod 5 passes through the through slot 12, the long screw rod 5 is provided with a through through slot 2 51, the protrusion 11 is threadedly connected with a bolt 13, the bolt 13 passes through the through slot 2 51, the hole 211 is connected with a shaft rod 212, and the shaft rod 212 passes through the through slot 2 51.

[0027] Both ends of the long screw rod 5 are threadedly connected with nuts 52 , one of the nuts 52 is in contact with the outer template 1 , and the other nut 52 is in contact with the inner template 1 .

[0028] Both ends of the pull rod 6 are threadedly connected with nuts 3 61, one of the nuts 3 61 is in contact with the outer template 1, and the other nut 3 61 is in contact with the inner template 1. In this way, deformation of the mold during the grouting process is avoided.

[0029] The bottom of the mold in the accompanying drawings is not sealed because when the concrete guardrail is constructed on an elevated structure, a concrete base plate has been cast under the inner template 2. Since the entire guardrail is cast directly on the concrete base plate, there is no need to seal the bottom.

[0030] In summary, the reinforced concrete guardrail forming template is composed of an outer template 1 and an inner template 2. The outer template 1 is welded with a screw 3, and the inner template 2 is welded with a bent steel bar 22. The height of the inner template 2 is adjusted by the cooperation of a nut 31 and a pressure plate 4, so that the top of the inner template 2 is flush with the top of the outer template 1. The two templates are limited by setting a tie rod 6 and a screw 3 to prevent the mold from deforming during the process of pouring concrete slurry into the mold. This avoids linear irregularities, top surface ups and downs, and twisting after demolding.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
