IPC: E04B1/32
Filed: 1990-03-30
Abstract: The invention relates to a construction element (1) for a soundproofing shed, as is employed for the ground testing of jet-engined aircraft. Such sheds have perforations, extending in the shed transverse direction, for admitting fresh air and mutually spaced layers of sound-absorbing material (10, 11) which are arranged on the inside of the shed roof and between which are formed air passage gaps for fresh air entering the shed space. The present invention solves the object of being able to carry out erection of such a soundproofing shed within a shorter time and more cost-effectively. The solution of this object according to the invention provides, in a preferred embodiment, prefabricated construction elements (1) for building a shed, which contain, in the shed longitudinal direction, stepped roof-slab elements (2) retained by a supporting structure (5), as well as a first (10) and second (11), mutually spaced element made of sound-absorbing material. By lining up and connecting the supporting structure (5) in the shed transverse and longitudinal direction, inlet air gaps extending over the entire roof length in the shed transverse direction and passing between the damping layers are produced. Since the shed roof can be assembled from prefabricated building elements (1), the soundproofing shed can be erected within a short time and cost-effectively.
