Tecnaria CTL BASE timber-concrete connector

Description

The Tecnaria CTL BASE timber-concrete connector strengthens and stiffens existing timber floors by forming a composite concrete slab. The CTL BASE consists of a square 50×50 mm base plate 4 mm thick, formed with teeth, a Ø 12 mm cold-assembled steel stud and two Ø 8 mm coach screws (lengths 70, 100 or 120 mm) passing through the plate. Screwed through the decking into the joists, the CTL BASE ties the old timber structure to the slab poured over it; its parts are electrolytically galvanised (8 µm, 2 Kesternich cycles) and the assembly is CE certified. The characteristic resistance Fv,Rk of the CTL BASE reaches up to 19.5 kN depending on the thickness of the decking and the timber class, the minimum timber class required being C16, GL24 or D30. The CTL BASE comes in several heights (from 20 to 200 mm) to suit the intended slab thickness. The documentation for the CTL BASE includes its technical data sheet, an ETA, a declaration of performance (DoP), an Avis Technique and installation instructions.
