Abstract: A method for creating a tapered spiral welded conical structure where the overall shape of the cone is first graphically slit axially and unwrapped, and then a series of construction arcs and lines are created to form the edge lines of a strip that can then be wrapped (rolled) to form a tapered conical structure. The edges of the spirally wound strip can be welded together, and a very large conical structure can thus be achieved. Various construction options are presented from a constant width strip to strip made from straight segments. Equations are given for the formation of the strips to enable those skilled in the art of spiral welded tubing to practice the invention.

Abstract: A pre-fabrication of a modular reinforcement cage for high-rise concrete construction is provided. The primary vertical bars, often referred to as the longitudinal bars, are held in formation by a set of templates that are manufactured to the design of the construction. These templates ensure accurate placement of the vertical bars and provides great rigidity for the module when being placed in the field. The main vertical bars can have thread-like deformations along the length of the bar, and are locked in place by use of compatible hardware against the templates. Multiple modules can then be stacked and coupled by use of mechanical couplings as construction continues.

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. According to the invention the stirrup or tie consists of a load-bearing element for the fixing of the longitudinal rebars and for the undertaking of the tensile forces which develop during the loading of the structural members. The load bearing element consists of at least one cell of closed shape so that the flow of the tensile stresses developed in the cross section is closed and the stresses are not diffused to the concrete. 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.
