FIELD: construction.
SUBSTANCE: retained folding formwork for construction of cast-in-situ walls includes parallel panels and hinged ties, vertical posts with panel and tie attachment devices located on external side of vertical post throughout their height. Panels of formwork are meshed, hinged ties are attached to vertical posts so that they can be turned in attachment devices, each one is made in the form of a zigzag so that sections inclined in plan view to surfaces of panels and sections in bend area, which are parallel to flat external wall of vertical post and contact it, are formed; at that, two hinged ties adjacent as to height are located in opposite phase relative to each other and fixed on posts in a staggered order. Hinged ties are fixed at one and the same height of opposite posts and located in one and the same plane.
EFFECT: improving stiffening characteristics of formwork system at the concreting stage and increasing the strength of sections of the built construction.
