Plate shaped sound proof element for between parallel supports - has rubber elastic seals and long webs on frame which engage in support space between double-T supports

摘要

The element (3) has two long webs (5, 6) on a frame on the outside when in the assembled condition. There are agents on the outer edge to hold rubber-elastic seals (7, 8) during assembly. The webs engage in the U-shaped support space between two parallel double-T supports (1, 2) and the seals lie on the inner side of the corresponding support face. There are three inward protruding webs on the inside of the U-shaped frame profile. One of these runs along the profile centre line and the other two run along the side flanges of the profile at a small distance from it. At least two of these webs can hold the dampening element between them. USE/ADVANTAGE - For street construction. Has a simple assembly, with few tolerance problems and is held securely in place.
