Specific implementation mode

[0020] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0021] Please refer to Figures 1-4 , a safety fence for building construction, including a main support column 1. Installation grooves 2 are opened on both sides of the main support column 1. A fence housing 3 is rotatably connected in the installation groove 2. An inner fence 4 is slidably arranged inside the fence housing 3. Auxiliary support columns 5 are fixedly connected to the mutually remote ends of the two inner fences 4. Limit posts 6 are fixedly connected to the upper and lower sides of the opposite ends of the two inner fences 4. Limit grooves 7 adapted to the limit posts 6 are opened on the upper and lower sides of the fence housing 3. The limit posts 6 are slidably arranged in the limit grooves 7. By arranging the limit posts 6 and the limit grooves 7, the inner fence 4 can be limited to prevent the inner fence 4 from detaching from the fence housing 3 during the process of being pulled outwards. A storage groove 8 is opened at the rear side of the auxiliary support column 5. An auxiliary support mechanism 9 is arranged in the storage groove 8 for post-supporting the auxiliary support column 5 to improve the stability of the guardrail. The auxiliary support mechanism 9 can be folded and stored in the storage groove 8 for convenient folding transportation. When transporting the guardrail, by sliding the two inner fences 4 in the opposite direction to retract them into the fence housing 3, and then rotating the two fence housings 3 to fold the two fence housings 3 together, the space occupation ratio of the guardrail is greatly reduced, thus facilitating the carrying and transportation of the guardrail.

[0022] Furthermore, bottom plates 10 are fixedly connected to both sides of the bottom ends of the main support column 1 and the auxiliary support column 5. First positioning holes 11 are opened on the bottom plates 10 for fixing the main support column 1 and the auxiliary support column 5. By arranging the auxiliary support mechanism 9, the auxiliary support column 5 can be post-supported to improve the stability of the guardrail.

[0023] Furthermore, warning lights 12 are arranged at the tops of the main support column 1 and the auxiliary support column 5, which can play a warning role and are used to remind passers-by at night to stay away from the construction ahead.

[0024] Further, the auxiliary support mechanism 9 includes a sleeve rod 901 rotatably connected to the top of the storage groove 8. The bottom end of the sleeve rod 901 is open. A support rod 902 is slidably arranged inside the sleeve rod 901. The bottom end of the support rod 902 is hinged to a support foot 903. A second positioning hole 904 is formed in the support foot 903. An adjusting assembly 905 is arranged between the support rod 902 and the sleeve rod 901. The length of the sleeve rod 901 is less than the length of the storage groove 8. When the support rod 902 is completely retracted into the sleeve rod 901, the sleeve rod 901 and the support foot 903 can be folded and stored in the storage groove 8. When using the auxiliary support mechanism 9, the sleeve rod 901 is rotated outwards, and then the support rod 902 is pulled downwards. Through the cooperation of the adjusting assembly 905, the support rod 902 is adjusted to the required length. Then the support foot 903 is brought into contact with the ground. Finally, the ground nail is inserted through the second positioning hole 904 and inserted into the ground to fix the support foot 903, thereby completing the rear support of the auxiliary support column 5 and improving the overall stability of the guardrail.

[0025] Further, the adjusting assembly 905 includes a fixing screw 9051 inserted through the near end of the bottom end of the sleeve rod 901. A plurality of threaded holes 9052 which are equidistantly spaced and adapted to the fixing screw 9051 are formed through the support rod 902. By providing the adjusting assembly 905, the support rod 902 can be pulled out to different lengths, thereby adjusting the support angle of the auxiliary support mechanism 9.

[0026] During use, first expand the two fence shells 3 to both sides until the two fence shells 3 are in a straight line. Then move the two auxiliary support columns 5 in opposite directions, driving the inner fence 4 to move at the same time. When the limit post 6 moves from one end of the limit groove 7 to the other end, the inner fence 4 is pulled out to the maximum value. Then, through the cooperation of the ground nail and the first positioning hole 11, the main support column 1 and the auxiliary support column 5 are positioned and installed on the ground. Then the lower end of the sleeve rod 901 is rotated outwards from the storage groove 8, and then the support rod 902 is pulled downwards to an appropriate length. Then, by inserting the fixing screw 9051 into the corresponding threaded hole 9052, the support rod 902 is limited and fixed. Then the support foot 903 is arranged in contact with the ground. The ground nail is inserted through the second positioning hole 904 and inserted into the ground to fix the support foot 903, thereby completing the rear support of the auxiliary support column 5 and improving the overall stability of the guardrail.
