Column-foundation connection

The innovation of the new B.S. CONTINUITY CONNECTION SYSTEM with INJECTION SLEEVE for the foundation/column and column/column connection has the following features:

Vertical height adjustment
The system allows for adjustment of the set height and the verticality of the structure in order to absorb any errors in the foundation castings in addition to specific plumbing systems: brackets, threaded rods, RS25.

Very high coupling tolerance
Thanks to the large diameter of the sleeve.

Anchorage in continuity
Guaranteed by the reinforcement of the foundation itself continuing towards the column / or the reinforcement of the column continuing towards the same (perfect emulation of in-situ structures).

The sleeve can be used with rebars of different diameters: from ø 12 to ø 32.

Double adherence
The shape of the sleeve is designed to ensure internal and external adherence of the system.

Guarantee of ductility
High ductility steels are used.

Excellent fire resistance
B.S. Italia’s anti-seismic Continuity Connections are adequately covered and therefore protected by the concrete of the structure.

Fixing set
The sleeves are secured by means of a special fixing/centering system which can be connected to the metal templates. The metal templates are therefore fundamental for the correct positioning of the inserts. B.S. Italia S.p.a. can offer, subject to commercial agreement, specific consultancy for the design/manufacture of the templates and technical assistance at the place of production of the products and/or on site.

Structural calculation
This is not necessary given the guaranteed emulation of traditional in-situ solutions. The system guarantees perfect continuity of the reinforcements between the two reinforced concrete structures (ex. column-foundation or column to column ). The connection provides guaranteed structural continuity and therefore does not require any additional calculation.
