Abstract: The present invention refers to stirrups and ties for structural members. Such stirrups and ties are used in all the structural members like columns, beams, slabs, footings, piles, chainages, lintels etc. The invention refers also to a method of reinforcement of structural members and to the structural members themselves.

The load bearing element of the stirrup or tie in accordance to the invention has a continuous cross section and thus there are no free ends as in the known stirrups. In this way anchoring of the stirrups or ties is completely avoided.

Abstract: Site cast or pre-cast columns aligned and braced by pre-cast pre-stressed floor beams are used to erect a concrete skeleton structure for a building. The ends of the horizontal beams are imbedded in the columns at floor levels to stabilize and complete the skeleton. The horizontal beams are pre-stressed and are cast with passages that permit insertion of continuous reinforcing tendons into a network throughout each floor level. The tendons are subsequently post-tensioned so to tie the beams together and to the columns to reinforce the skeleton. Slab drop-forms starting at the roof and progressing floor-by-floor downward allow monolithic post-tensioned floor slabs to be cast to tie the skeleton into a unitary structure. The beams are usually integrated (buried) into each monolithic floor slab, keyed, doweled and bonded with bonding agent at cold joints to become a part of the slab structure.

The invention relies upon the use of cold-formed metal that is shaped to provide a ring beam which will accommodate the various criteria. A basic shape configuration has been generated to provide the most efficient utilization of materials. Simplifying installation for the many variable conditions that occur in buildings is therefore provided by this modular design, wherein designers and contractors can easily select and use specialized components to meet all design and construction requirements.

Abstract: This invention relates to a method of connecting precast components to each other. More precisely it is a coupling system for joining structural concrete components for use in the construction industry. This invention is a coupling of and for precast concrete components, the precast concrete members rely on being cast with a precisely formed monolithic “maile or femaile” (inverse coupling) shape that slips together easily with the mating component. When these components are joined they create an interlocking assembly (connection zone). In the connection zone, concrete grout is placed before the components are joined, as they are connected gravity and the components weight seat the coupling in compression. When the grout cures a permanent structural, monolithic coupling is formed.
