PROFILE LEDGES AND WEDGE CONNECTIONS PROFILE LEDGES MADE OF STEEL Triangular and trapezoidal ledges made of steel: G To produce fractional edges and trapezpoidal recessed pointings at concrete elements Delivery lengths 3 – 4 m G Special measurments on request G General information: ROBUSTA-profile ledges are very important parts, if formwork with chamfered edges is needed or if dummy joints are necessary at prefab elements. All kinds of profile ledges made of steel can be welded into steel formwork in a run of spot welds with thin welding electrodes. To prevent depressions because of...

PROFILE LEDGES AND WEDGE CONNECTIONS SEALING PROFILES Sealing profiles made of flexible material: G For producing chamfered edges at concrete elements Flexible use in all kinds of formwork because of adjusting of material Triangular sealing profile DK 10: Inexpensive alternative to the weldable triangular ledges 10 x10 mm which can be removed after use without effort. Insertable onto sheets t = 4 to 5 mm. Optimum sealing property because of flexible adjusting of the corners. Because of the bending of the plastic also suitable for rounded formwork. Triangular sealing profile to seal at the...

PROFILE LEDGES AND WEDGE CONNECTIONS SEALING PROFILES Special sealing profile “pine-tree“ This special profile offers essential advantages compared to the conventional sealing rings: The continuous hollow space guarantees a relative long squeezeing range. A lateral upwards standing lamination prevents a removing out of the joint. Important with heated formwork: proofed up to approx. 80° C. Sealing profile R 12: Rubber sponge sealing ring made of quality EPDM as a propitious version to the profile G 13. Usage of the profile “pine-tree” with ROBUSTA-round column formwork prevents the leaking...

PROFILE LEDGES AND WEDGE CONNECTIONS WEDGE CONNECTIONS For self construction of formwork To connect steel profiles Especially to close small steel formwork, if angle- or U-profiles have to be connected. To adjust to the clamping width we deliver loose washers, to weld them on the spot accordingly. If needed these bolts can be welded directly into the steel construction without washer. TECHNICAL DATA: Key bolts made of steel with loose sheets Indication or Ø [mm] Wedges made of steel Indication 15 gib key: 15/40 x 260, 8 mm thick, hardened and galvanized wedge: 22/30 x 150, 8 mm thick,...
