The present technology relates generally to a platform and concrete composite slab system used as a building material. A platform, is formed from joined, substantially coplanar boards with connector plates partially embedded between the boards such that a portion of the connector plates extend above the platform's top surface. A reinforcing material (e.g., wire mesh and/or rebar) can be arranged on the prongs or other portion of the connector plates spaced above the platform and concrete is poured over the reinforcing material and allowed to cure, forming a reinforced concrete layer that encases the connector plates and reinforcing material. The connector plates act as standoffs and help to suspend the reinforcing material in the middle of the concrete layer to increase the strength of the reinforced concrete and to fixedly anchor and bind the concrete layer to the platform, so as to establish a composite action between the platform and the concrete.

The present invention is a modular structural building method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

An anchor for connecting a concrete layer of a floor to a cellulosic layer of the floor, the cellulosic layer comprising a plurality of cellulosic members joined together in a side-by-side arrangement, the anchor including a first portion to extend between two adjacent cellulosic members of the cellulosic layer into the concrete layer of the floor. The first portion includes attachment structure to attach the first portion to one of the two adjacent cellulosic members of the cellulosic layer to attach the anchor to the cellulosic layer. An upper edge margin of the first portion is disposed within the concrete layer when the first portion is attached to the cellulosic layer. A second portion extends from the upper edge margin in a first direction that is transverse to the first portion. The second portion is spaced apart from the cellulosic layer and embedded within the concrete layer of the floor to attach the anchor to the concrete layer.

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.
