A protective fence for construction engineering

Abstract

The utility model relates to the technical field of construction engineering, specifically a guardrail for construction engineering, including a vertical pole, two sides of the vertical pole are respectively fixedly connected with a connecting block 1, the interior of the connecting block 1 is movably connected with a connecting shaft 1, the top of the connecting block 1 is fixedly connected with a limiting plate, one side of the limiting plate is fixedly connected to one side of the vertical pole, and the side surface of the connecting shaft 1 is movably connected with a movable block 1. The guardrail for construction engineering limits the rotation angle of the support rod by the limiting block and the limiting plate. After the support rods on both sides of the vertical pole rotate to a preset angle with the connecting shaft 1 as the axis, the limiting block will stick together with the limiting plate, so that the support rod cannot continue to rotate. At this time, the vertical pole and the support rods on both sides just form a stable tripod. The friction force obtained by the pads 1 and 2 at the bottom of the pads 1 and 2 in contact with the ground ensures that the guardrail will not fall forward or backward, and can avoid the damage of the rivets to the ground from the root.

[0027] The use method and advantages of the utility model: When the guardrail for construction engineering is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the guardrail is divided into a bracket part and a guardrail part. The guardrail is installed between two brackets. First, the bracket needs to be unfolded and placed on the ground. The bracket includes a vertical pole 1, which is connected to the ground through a pad 12 connected at the bottom. Two identical support rods 7 are arranged on both sides of the vertical pole 1. The support rod 7 is connected to the ground through a pad 11 at the bottom. A movable block 5 is fixed on the top of the support rod 7. The movable block 5 is connected to the connecting block 2 through a connecting shaft 3. The limit block 6 on the top of the movable block 5 and the connecting block 2 are connected to the connecting block 2 through a connecting shaft 3. The limit plate 4 on the top of the block 2 is used to limit the rotation angle of the support rod 7. After the support rods 7 on both sides of the vertical pole 1 rotate to a preset angle with the connecting shaft 3 as the axis, the limit block 6 will stick to the limit plate 4, so that the support rod 7 cannot continue to rotate. At this time, the vertical pole 1 and the support rods 7 on both sides just form a stable tripod. The friction between the pad 11 and the pad 2 12 at the bottom and the ground ensures that the guardrail will not fall forward or backward. Two fixing hooks 13 are connected to one side of the vertical pole 1. The fixing hooks 13 are used The guardrail is connected. The guardrail mainly includes a railing 16 and a railing 2 19. The railing 16 is provided with a slide groove 17 inside which the railing 2 19 can be extended and retracted.

The limiting ring 18 is fixed to the slide groove 17, and the limiting ring 20 is fixed to the side surface of the railing 2 19. The limiting ring 20 and the slide groove 17 are in a movable connection relationship, which makes the limiting ring 18 move to a certain extent when the railing 2 19 moves to the limit ring 18. The railing 20 will be in contact with the limiting ring 18, thereby ensuring that the railing 2 19 will not be separated from the railing 16, and at the same time it can also meet the requirements of different widths of the guardrail. A number of railings 2 19 and railings 1 16 are linearly distributed and the two ends are respectively fixed with the side panels 15 and the side panels 21 to form the guardrail part of the guardrail. The two sleeves 14 are respectively connected to the opposite sides of the side panels 15 and the side panels 21, and the sleeves 14 are sleeved on the fixing hooks 13. The distance between the two brackets is manually adjusted to complete the installation of the guardrail.
