Warning fence for engineering safety near-edge protection

Abstract

The invention discloses a warning fence for engineering safety near-edge protection. The fence comprises a fence plate and fence columns located at the two sides of the fence plate, vertical cavitiesare formed at the two sides of a frame of the fence plate correspondingly, and guide rods are fixedly connected between the upper inner walls and the lower inner walls of the two vertical cavities correspondingly. The two vertical cavities are each movably sleeved with a vertical plate through two guide rods. By means of the rotatable design of fixing cylinders in the vertical direction, when L-shaped fixing pieces and the fixing cylinders are staggered in the vertical direction and cannot be matched, the L-shaped fixing pieces can be matched by rotating and adjusting the vertical angles of the fixing cylinders; and through the adjustable design of the vertical height of the fixing cylinders, when the vertical heights of the L-shaped fixing pieces and the fixing cylinders are staggered andcannot be matched, the L-shaped fixing pieces can be matched by adjusting the height of the fixing cylinders, the device can adjust the heights of the two fixing cylinders located at the same side atthe same time, and it is guaranteed that the distance between the two fixing cylinders at the same side is always equal to the distance between the two L-shaped fixing pieces at the same side.

Description

technical field [0001] The invention relates to the technical field of engineering safety, in particular to a warning fence for edge protection of engineering safety. Background technique [0002] The warning bar for engineering safety border protection is a device that delineates the area to be constructed in the engineering building and warns to prevent outsiders from entering. [0003] The L-shaped fixing piece and the fixing cylinder of the warning fence for traditional engineering safety border protection are fixedly connected with the column and the fence respectively. When the ground where the column is located is an uneven surface such as a slope, the L-shaped fixing piece and the fixing cylinder The dislocation in the vertical direction cannot be matched. At this time, the traditional method is to level the uneven ground. For rocky ground, it is more difficult to level the work. In addition, when the ground below the fence is a slope, the height of the fence The he...

[0003] The L-shaped fixing piece and the fixing cylinder of the warning fence for traditional engineering safety border protection are fixedly connected with the column and the fence respectively. When the ground where the column is located is an uneven surface such as a slope, the L-shaped fixing piece and the fixing cylinder The dislocation in the vertical direction cannot be matched. At this time, the traditional method is to level the uneven ground. For rocky ground, it is more difficult to level the work. In addition, when the ground below the fence is a slope, the height of the fence The height will be higher than the height of the balusters, resulting in a vertical misalignment between the L-shaped fixing piece and the fixing tube, and the length of the balustrades is longer. The traditional method requires all the slopes under the balusters to be leveled. Difficult and time-consuming
