FIELD: building, particularly for reinforced concrete structure erection. ^ SUBSTANCE: form has universal modular contour profile and transversal profile having rectangular cross-sections. Peak made as angle member is secured to lesser side of contoured profile by one shoulder thereof. Another peak shoulder is flush with outer surface of long rectangle side of contour profile. Secured to lesser side of transversal profile are rests defining slots arranged with periodic spacing between transversal profile and plywood deck. Conical bushes are secured in conical orifices of contour profile so that lesser diameters orient towards plywood deck. Form staging are made as frame with L-shaped brackets having catchers to cooperate with transversal profiles and fixers. Catcher cross-sections mate with that of slots. Struts are provided with locks pivotally secured to ends thereof and cooperating with transversal profiles. For lock installation locks are initially opened by moving wedge outwards and rotating double-armed lever with movable drip in counter-clockwise direction, placing thereof on contoured profile and transversal profile and closing thereof in reverse direction along with applying force to cam by wedge and closing the locks. ^ EFFECT: increased reliability, reduced time for form assembly and disassembly. ^ 9 cl, 11 dwg |
