Fence for constructional engineering

A fence for constructional engineering is characterized in that fixing seats are mounted at the bottom ends of vertical columns of the fence, cross beams are mounted between inner cylindrical surfaces of every two adjacent vertical columns, two ends of a transverse plate of each vertical column extend towards two sides of the corresponding vertical column, a plurality of screw fixing holes are formed in each transverse plate, and diagonal bars are mounted in the middles of the inner cylindrical surfaces of the vertical columns. The upper ends of upper supporting rods of the inclined supporting rods are rotationally connected with the stand columns through pin shafts, the lower ends of the upper supporting rods are connected with the upper ends of lower supporting rods through internal and external threads, and the tip ends of the lower ends of the lower supporting rods are supported on the ground. The length of the two ends of the transverse plate extending towards the two sides of the stand column can cover
