Abstract

Abstract An elongated channel-shaped structure, preferably of anodized extruded aluminium, is suitable to form the load bearing beam of a false ceiling assembly, in particular comprising absolute filters for the so-called "clean rooms". Such a structure is U-shaped and comprises an elongated and uninterrupted central slot or groove for the fixing to the ceiling, with the concavity of the U-shape directed downward, having outer lateral finnings for the cooling, outer grooves and projections for the coupling with transverse spacers and for supporting absolute filters, as well as inner grooves and projections for supporting electric lines, pipes and other devices and systems. There are also provided extension members directed downward, to be fastened to said structure and having further support and guide fit grooves.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 97 words
1 . A multiple-use channel-shaped structure for false ceilings, in particular for supporting absolute filters, which is channel-shaped, elongated and uninterrupted, adapted to be mounted to the ceiling with the concavity in the downward direction by means of a central continuous slot (3), characterized by the fact of being provided with outer cooling fins (4, 4') and outer recesses (9, 9') for the connection with cross spacer members (11); inner grooves (6) for the coupling with head plates (T); supporting inner recesses and beads 5, 7, 8); and outer brackets (10) for supporting said absolute filters (12).
Claim 2
Dependent Claim 97 words
1 . A multiple-use channel-shaped structure for false ceilings, in particular for supporting absolute filters, which is channel-shaped, elongated and uninterrupted, adapted to be mounted to the ceiling with the concavity in the downward direction by means of a central continuous slot (3), characterized by the fact of being provided with outer cooling fins (4, 4') and outer recesses (9, 9') for the connection with cross spacer members (11); inner grooves (6) for the coupling with head plates (T); supporting inner recesses and beads 5, 7, 8); and outer brackets (10) for supporting said absolute filters (12).
Claim 3
Dependent Claim 94 words
A structure according to claim 1, characterized in that it is formed of three anodized extruded aluminium sections, one central of which (la) is substantially U-shaped and has said central slot (3); and two side ones (1',1") which comprise a first portion being substantially the continuation of said central section (la), and a second portion (lb) being substantially parallel to the symmetry plane of the structure, there being also provided flanges (2, 2') with fittings and seals for the connection between said central section (la) and said side ones (1 1 , 1") .
Claim 4
Dependent Claim 46 words
A structure according to claim 1, characterized by further comprising coupling means for the uninterrupted fixing of a substantially vertical section (20) to each lower end of the structure, said vertical section (20) being also provided with inner recesses and a continuous profiled groove directed downwards.
Claim 5
Dependent Claim 84 words
A structure according to claim 1, characterized by further comprising, for fixing said cross member (11) a taking up assembl comprising a first bolt (21) with threaded shank, head and polygonal plate (22) to be inserted into one of said outer recesses (9), a tubular member (25) with throughhole in the cross-section direction for the insertion into opposite housings formed in side walls (lla, llb) of the cross member (11), and a nut (24) and washer (23) unit for positioning and tightening the assembly.
Claim 6
Dependent Claim 101 words
A structure according to claim 1, characterized by further comprising for fixing the absolute filters (12) a chuck device comprising a second bolt with threaded shank (15), and nut to be inserted in a counterbored recess (14) formed in a vertical central wall (13) of the cross member (11), and having a ring nut (19) screwable at the opposite end of the shank and a spring element (18) compressed between the ring nut (19) and an apertured stop plate (16) for supporting the filter, said stop plate (16) having also two vertical side teeth (17) which prevent the same from rotation.
