    摘要: A waterproof and weatherproof roof deck assembly comprises a plurality of beams, and a plurality of adjacent waterproof panels that rest on the beams. Each panel has a shoulder on all sides thereof that is adjacent to the shoulder of another adjacent panel to form a joint. A strip of deformable material is disposed onto the adjacent shoulders and compressed against the shoulders by a compressing means that is placed against the material. An urging means forces the compressing means against the deformable material and a suitable sealant is placed into the joint and is subsequently bonded to the sides of the panels to form a waterproof and weatherproof joint.

    摘要: An anti-fall safeguard for persons includes a supporting base with which the anti-fall safeguard can be set up on an underlying surface formed of individual concrete slabs. The concrete slabs are provided with upwardly projecting iron reinforcing elements and with an anchor mast system which is connected to the supporting base. Personal protective equipment is fastened to the free, upper end of the anchor mast system. In order to securely fasten the anti-fall safeguard on an underlying surface, two or more cable safeguards are provided, which can be brought into connection with the iron reinforcing elements of the concrete slabs. The cable safeguards can be tensioned and the supporting base is immovably secured on the underlying surface by the tensioning of the cable safeguards.
