Method for erecting framework of structures

Abstract

The invention concerns the construction process and can be employed in the course of construction of buildings and structures of different purposes in order to reduce labor consumption during formation of floor slabs, and to facilitate integrity retention of a slab and hoisting equipment during the rotation operation. The carcassing method assumes simultaneous construction of bearing solid-cast reinforced-concrete structural vertical elements and hinged to them vertically oriented reinforced-concrete pivot floor slabs. The construction process involves preliminary installation of separating elements between slabs and bearing structures as well as between adjacent slabs. After the concrete has developed its strength, the above slabs shall be flipped to the horizontal position and butt joints between slabs and bearing vertical elements as well as between adjacent floor slabs shall be grouted. The vertical elements and floor slabs are formed in layers, vertical partition elements represent sheet-type or film-type polymer materials, the pivot hinge of floor slabs represent an elongated element located in the middle portion of a floor slab and whose longitudinal axis coincides with the slab rotation axis. Bearing elements shall be formed as columns. Tubular round-in-section hinge elements of horizontally adjacent floor slabs shall be located at opposite sides of the longitudinal axis of a column. Floor slabs shall be reinforced by a prestressed reinforcement cage made of a sheathed steel cable. Tendons shall be installed inside of floor slabs after their formation. For this, the solidifying grout is fed into cavity of the slip formwork inside a slab, linear voids are formed by means of channel formers. The longitudinal axis of a hinge runs through the mass center of a floor slab. Slabs shall be flipped in the ascending and descending order. Channel formers shall be shifted upon shifting the formwork or upon transition to the next layer. Channel formers shall comprise the broach for installation of tendons in channels. Channel formers are equipped with vibrators for compaction of the grout. After rotation of slabs, the reinforcing cable shall be placed inside transverse channels and shall be tensioned.
