For example, as shown in a prefabricated guardrail with Chinese patent application number CN202023339358.7, the size and required quantity of the prefabricated guardrail are determined according to the size of the organized external drainage roof without damaging the roof, and the prefabricated guardrail is standardized, which is conducive to mass production and transportation management, simplifies construction difficulty, and realizes green construction. In addition, the guardrail can be disassembled and re-used repeatedly to maximize the assembly rate and increase the construction speed.

[0003] However, when the guardrail is in use, the bundled safety mesh on the steel pipe is used to block construction waste. Since the safety mesh is in the air and there is a lack of a high-altitude stretching device for the safety mesh on the steel pipe, it is easy for the safety mesh to fall off in windy weather.

[0011] Furthermore, a buckle is provided on the rod body of the support frame, and a steel pipe for fixing the two adjacent support frames is fixedly installed between two adjacent buckles. An oblique rod for supporting the vertical rod is fixedly installed on the frame body of the support frame on the right side, and a connecting rod for supporting the oblique rod is fixedly installed on the top of the oblique rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By arranging a safety dense mesh device and a stretching device, the guardrail can be adjusted according to the construction requirements based on the spacing of the support frames. When the production is completed according to the on-site construction conditions, the hand wheel can be used to drive the screw rod to rotate, thereby driving the movable plate to move left and right along the rod body of the screw rod; the steel wire rope on the top of the hinged plate can be driven to control the safety dense mesh on the vertical rod to stretch, thereby preventing the safety dense mesh device on the vertical rod from shaking and falling off.
