Abstract
Proposed is a double-walled formwork element comprising two large-area panels suitable for use as mould shuttering, particularly in the concrete construction industry. The two panels are joined to each other by force-locking, liquid-tight and gas-tight engagement, and form between them a cavity. The invention secures the two layers of shuttering against slippage and ensures the discharge of any leak liquid produced. The invention also enables shuttering systems to be assembled cheaply and simply for constructions of various shapes.
Claims16
A double-walled formwork element of thermoplastic material for covering concrete walls, comprising:
- a) a first lining panel (2) with a plurality of anchoring knobs (3) for anchoring in the wall (1), and
- b) a second lining panel (4), wherein
- c) the first and the second lining panel (2 and 4, respectively) are joined to each other by a plurality of connecting knobs (6) on the side which is faced away from the wall (1) by force-locking, liquid-tight and gas-tight engagement,
- d) the plurality of connecting knobs (6) simultaneously serve as spacers between the first and the second lining panel (2 and 4, respectively), thus forming a cavity (7) between the first a the second lining panel, and
- e) wherein the connecting knobs (6) are inserted into bores (5) of the first lining panel (2).
