The utility model discloses a fence device for civil construction, and particularly relates to the technical field of construction fences, which comprises a mounting rod, a baffle is mounted on one side of the mounting rod, a plurality of fixing pipes are mounted at the top and the bottom of the outer wall of the mounting rod, and a plurality of supporting pipes are obliquely arranged on one side, far away from the baffle, of the outer wall of the mounting rod. A socketed
pipe is arranged on one side, close to the fixed
pipe, of the baffle; the end, close to the mounting rod, of the fixing
pipe is rotationally connected with a sleeving ring, and the end, away from the mounting rod, of the fixing pipe is internally and slidably connected with an extension rod; supporting rods are slidably connected into the ends, away from the mounting rods, of the supporting pipes, rotating rings are rotatably connected to the ends, close to the mounting rods, of the supporting pipes, and fixing rings are rotatably connected to the ends, away from the supporting pipes, of the supporting rods. The utility model has the advantages that the fixing pipe can be conveniently adjusted to be connected with the baffles with different inclination angles, and the supporting pipe can be conveniently adjusted to be installed and fixed at different inclination angles.
