Shutter casing for use in concrete construction

摘要

The shutter (1) has at least two shuttering elements which are connected by fasteners at their edges (17,18), and which are especially made from sheet steel. The fastener has a first Z-shaped profile (9) with three limbs (11,12,13), and a second profile (10) with at least two limbs (15,16) at an angle to one another. A first limb (12,15) of each profile is fastened against the inside of a shuttering element. A second adjoining limb (11,16) is guided on the edge of the outside of a shuttering element. The third limb (13) of the first profile and the second limb of the second profile, form a positive connection with one another opposite the first and second limbs of the first profile.
