发明名称 CELLULAR STIRRUPS AND TIES FOR STRUCTURAL MEMBERS
摘要 <p>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 (20) for the fixing of the longitudinal rebars (10) and for the undertaking of the tensile forces which develop during the loading of the structural member. The bearing element consists of at least one cell of closed shape (50) 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. The closed cellular shape has no discontinuation and may be simple, i.e. rectangular, circular, T-shaped, I-shaped, etc. or complex i.e. square with inscribed rectangular, circular with inscribed square etc.</p>
