[0003] For example, the utility model with announcement number CN214993390U discloses a concrete guardrail formwork structure, including a base, a first side formwork and a second side formwork. The bottoms of the first side formwork and the second side formwork are clamped on both sides of the base by a first tension screw, and the tops are connected by a second tension screw. A sleeve is provided on the outer sleeve of the first tension screw, and the two ends of the sleeve are respectively passed through the first side formwork and the second side formwork. The support pipe is located at the top of the concrete guardrail and has the same size as the net width of the concrete guardrail. The second tension screw passes through the support pipe. During construction, the tightness of the formwork can be adjusted by the nut at the end of the second tension screw. The absolute size of the concrete guardrail is fixed according to the length of the top support pipe, which solves the problems that the conventional formwork steel pipe is only fixed with fasteners and the formwork is not easy to detect.

The outer side of the connecting block 313 is slidably connected to a pull rod 310 with one end passing through and extending to the inside of the insert block 39, and a spring 311 is fixedly connected between the pull rod 310 and the connecting block 313.

[0023] In this embodiment, the side formwork 33 is composed of a plurality of connecting formworks, and the plurality of connecting formworks can be plugged end to end and fixed by fixing screws 37, so that they can be extended and adjusted according to concrete guardrails of different heights, and the bottom formwork 31 and the top formwork 312 can be adjusted according to the width of the concrete guardrail after use, so as to adapt to concrete guardrails of different specifications. After fixing the bottom formwork 31, the side formwork 33 can be fixed by fixing bolts 32, and then after pouring, the top formwork 312 can be fixed by screws 35 and nuts 36 to increase the assembly convenience of the entire formwork component 3.

[0024] The bottom template 31 has a through hole inside for the fixing bolt 32 to pass through, and the upper end of the support block 34 has a connecting groove located outside the screw rod 35. The connecting groove is arc-shaped so that the connecting groove on the support block 34 allows the screw rod 35 to pass through.

[0025] In addition, a slot is provided at the lower end of the connection block 313 , and the specification of the slot matches the specification of the plug-in block 39 , so that the connection block 313 and the plug-in block 39 can be plugged in through the slot.

[0026] Secondly, a fixing groove is provided on the outside of the plug block 39 and is located outside the pull rod 310. One end of the pull rod 310 located inside the fixing groove is inclined, so that after the plug block 39 is plugged into the connecting block 313, it can be limited and fixed by the pull rod 310 extending into the fixing groove.

[0027] Then, one end of the pull rod 310 located on the outside of the connecting block 313 is T-shaped, the number of the plug blocks 39 is two, and the two plug blocks 39 are symmetrically distributed on the top template 312.

By replacing or adding any one of the connecting formwork specifications, the height of the side formwork 33 can be increased to adapt to concrete guardrails of different heights.

[0030] The working principle of the above embodiment is:

[0031] After the side formwork 33 is plugged in end to end through several connecting formworks and then fixed by fixing screws 37, the guardrail base 2 can be blocked and limited. By replacing or adding any one of the connecting formwork specifications, the height of the side formwork 33 can be increased to adapt to concrete guardrails of different heights. When the side formwork 33 is fixed to the bottom formwork 31 by fixing bolts 32, the side panels of the concrete guardrail can be blocked and fixed. At this time, casting can be carried out through the gaps at the upper ends of the side formworks 33 on both sides. The bottom formwork 31 and the top formwork 312 can be adjusted and used according to the width of the concrete guardrail to adapt to concrete guardrails of different specifications. After fixing the bottom formwork 31, the plug block 39 and the connecting block 313 can be plugged in to limit and fix the top formwork 312, and then the top formwork 312 is fixed by screws 35 and nuts 36 to increase the assembly convenience of the entire formwork component 3.
