Elevation-adjustable superflat floor formwork
The invention provides an elevation-adjustable superflat floor formwork, which comprises a square steel guide rail, square steel butt joint sleeves, a plurality of pieces of angle steel, a plurality of oppositely penetrating fastening screw bolts and a plurality of expansion screw bolts, wherein the square steel guide rail consists of two pieces of parallel square steel with the space being 2 to 3m; holes are drilled in the length direction at intervals being 1 to 2m and are used for fixing the oppositely penetrating fastening screw bolts; the square steel joint parts of the square steel butt joint sleeves are connected by internally connected sleeves; the length of the butt joint sleeves is 100 to 200mm; the two ends of the butt joint sleeves are embedded into the square steel guide rail for 50 to 100mm; a plurality of pieces of angle steel are used as connecting elements between the square steel guide rail and a structure base layer; the length of the angle steel is 80 to 100mm; a plurality of opposite passing fastening screw bolts are used as connecting fastening screw bolts between the square steel guide rail and the angle steel; the plurality of expansion screw bolts are in one-to-one correspondence to oval holes formed in the angle steel; and each piece of angle steel is anchored on a superflat floor structure base layer by two expansion screw bolts. The elevation-adjustable superflat floor formwork effectively solves the problem that the existing construction technology cannot meet the precision requirement of the superflat floor construction.
