[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As mentioned in the background art, aiming at the problem of low installation efficiency of the guardrail in the prior art. The present utility model proposes a safety guardrail for civil construction.

[0025] Embodiment 1

[0026] Refer to Figures 1 to 3 , a safety guardrail for civil construction, including a guardrail 1 and two identically structured columns 2. The columns 2 are installed on the ground by screws;

[0027] Connecting blocks 3 are provided at the four circumferences of the guardrail 1. Fixed blocks 4 are provided at both ends of the opposite sides of the two columns 2, and bolts 5 for connecting with the fixed blocks 4 are provided on the connecting blocks 3;

[0028] Universal wheels 6 are provided on both sides of the bottom of the guardrail 1 to facilitate the workers to carry the guardrail 1;

[0029] Mounting frames 7 are provided on the opposite sides of the two columns 2. A first screw rod 8 penetrates through the mounting frames 7 horizontally. Both opposite sides of the two first screw rods 8 are connected with clamping rods 9 through bearings. The opposite sides of the two clamping rods 9 are respectively in contact with both sides of the guardrail 1. Handwheels 10 are provided at the opposite ends of the two first screw rods 8 away from each other. The handwheels 10 are used to drive the first screw rods 8 to rotate, so that the clamping rods 9 move horizontally.

[0030] Anti-slip strips are provided on the opposite sides of the two clamping rods 9 to improve the clamping effect.

[0031] Connecting rods 11 are provided at the bottoms of the opposite ends of the two clamping rods 9 away from each other. The connecting rods 11 are horizontally slidably connected to the mounting frames 7 to guide the clamping rods 9.

[0032] The mounting frame 7 is in an L-shaped structure to facilitate the workers to rotate the handwheels 10.

[0033] Embodiment 2

[0034] Refer to Figures 1 to 3, grooves 12 are provided on both sides of the guardrail 1, connecting frames 13 are provided on both clamping rods 9, and screw rods two 14 penetrate vertically through both connecting frames 13; a round plate 15 extending into the groove 12 is provided at the top of the screw rod two 14; a handwheel two 16 is provided at the bottom of the screw rod two 14. Rotating the screw rod two 14 by the handwheel two 16 can drive the round plate 15 to rise and fall, and when the clamping rod 9 moves, it drives the connecting frame 13 to move horizontally.

[0035] The remaining structures are the same as those in Embodiment 1.

[0036] After installing the upright column 2, move the guardrail 1 on the ground through the universal wheels 6 to align the screw holes on the connecting block 3 with the screw holes on the fixing block 4. When the ground is uneven, after bringing the clamping rod 9 close to the guardrail 1, at this time the round plate 15 enters the groove 12, and then adjust the height of the round plate 15 to make the guardrail 1 in a horizontal state, so that the screw holes on the connecting block 3 can be aligned with the screw holes on the fixing block 4. After alignment, move the clamping rod 9 again to clamp the guardrail 1. At this time, the round plate 15 can continue to move horizontally into the groove 12 without affecting the height of the guardrail 1. Thus, the bolt 5 can be installed at this time, improving the assembly efficiency.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
