Flood protection device for locking building openings, has closing elements which, when closed, tightens sealing plate to framework and seals between sealant and joint between contact surfaces of sealing plate and framework

摘要

A framework (2) is fixed to brickwork (12) and is provided with recesses (30) for the closing elements (28) of a closing mechanism (26). A central actuator drives the closing elements to open and close. Closing the closing elements tightens a sealing plate to the framework and seals between a sealant (14) and a joint (54) between the contact surfaces (20,22) of the framework and sealing plate.
