Warning board for construction site

Abstract

The invention discloses a warning board for a construction site, and relates to the technical field of constructional engineering. The warning board comprises a supporting block, a warning board bodyand supporting columns. Through grooves matched with the supporting columns are formed in the top of the supporting block, and the bottom ends of the supporting columns are slidably connected with theinner walls of the through grooves through connecting blocks; the bottom of the warning board body is fixedly connected with the top ends of the supporting columns, fixed grooves are formed in the top, on the two sides of the through grooves, in the supporting block, and the tops and the bottoms of the inner walls of the fixed grooves are slidably connected with sliding plates; and movable grooves are formed in one sides of the sliding plates, and the tops and the bottoms of the inner walls of the movable grooves are fixedly connected with vertical rods. According to the warning board for theconstruction site, the height of the warning board can be freely and conveniently adjusted, thus using demands under different situations are met, compared with an existing adjusting mode, rapidnessand economy are achieved, and the time and labor are saved; and meanwhile, more economical cost is not needed, the warning board is convenient to put into use greatly, and thus the practicability of the warning board is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a warning sign for a construction site. Background technique [0002] The warning sign is the conventional emergency equipment on the car. Its appearance is generally triangular, so it is also called the triangle warning sign. The warning sign must strictly follow the requirements of the "Road Traffic Safety Law". It is a passive reflective body made of plastic reflective material. The principle is When a car owner encounters a sudden traffic accident on the road, he can use the reflective performance of the warning sign to remind other vehicles to avoid secondary accidents. [0003] Most of the warning signs on the existing construction sites are fixed in height, which cannot be conveniently adjusted according to the specific use requirements. At the same time, the bases used by the existing warning signs are mostly cylinders or cubes, which cannot be folded, ca...
