The utility model relates to the technical field of
building construction protective fences, in particular to a
building construction protective fence with a warning function, which comprises two positioning bottom plates, a support column and an
organic glass outer shell, the support column is arranged between the two positioning bottom plates, screw holes are arranged on the positioning bottom plates, and the
organic glass outer shell is arranged on the support column. The supporting columns are fixedly installed at the screw holes of the positioning bottom plates through connecting plates, the supporting columns are used for connecting the two positioning bottom plates, an
organic glass outer shell is arranged on one side of each supporting column, and a light-emitting
assembly used for prompting is arranged on each organic glass outer shell; the modular
assembly design is adopted, building and follow-up recycling are facilitated, the warning mark can be automatically supplemented with
light at night, it is ensured that the warning mark can still be clearly seen at night, all the light-emitting assemblies are arranged in the organic glass outer shell, the structure is compact, and meanwhile the light-emitting effect is good. The organic glass outer shell can protect the light-emitting
assembly and prevent the light-emitting assembly from being corroded by rainwater and the like, and
solar energy can be used for charging in the
daytime.
