Abstract

Especially shaped bendable section with one or two segmented surfaces running lengthwise and essentially made up of a sequence of rectangular and/or trapezoidal elements or tongues to which, depending on the section being U, C or double-C shaped, one or two flat laminar elements (13) or (13") are coupled so that they are positioned alternatively between the internal face of one tongue and the external face of the following one, thus connecting the tongues into forming a virtually continuous wall, so that when the section is forced into a certain shape involving a curve or a series of curves, element (13) or elements (13") bend into the same shape which can be fixed and held once elements (13) or (13") are riveted or punched to the section's segmented walls. The invention to be used in building single or double curve false-ceilings, curved walls, interior finishing, domes, etc.

Description

Curved profiles with one or more walls sliding and fixed.

Technical field

The invention allows, to types of profiles particularly shaped, the realization and self maintenance of any type of curvatures or series of curvatures with simply redouble or with the punching of flat elements belts on the wings, thus making them more rigid and supportive, in the realization of curved false skies with single or double curvature, curved walls, interior finishes, domes, etc.

Purposes and advantages of the invention

The purpose of the invention, for the realization of curved false skies with single or double curvature, curved walls, interior finishes, etc., is to confer to a profiling that has incisions and holes that create segmented or winged edges or profiling surfaces, as for example in the utility patent application SA97U000021 of the same applicant, the ability to bend and acquire curvatures or double curvatures and the possibility that the bending can be distributed at the same time among all the wings more especially confer greater rigidity once it is set the curvature
desired.

In particular the main objective of the present invention is that, according to the intentions above exposed, when a particularly shaped profile of the type with section U or section C is forced to take certain curvature, an additional element slides between the wings and turns the necessary radius of curvature which is then blocked by medium of reddocks forming a continuous wall that provides rigidity and  overall stability

A further main objective of the present invention is that when a particularly shaped profile, of the type with section to double C or with another section of interest, is forced to take certain curvature, two additional flat elements slide between the wings and take the necessary radius of curvature which is then blocked by reddocks forming a continuous wall that brings rigidity and stability to the whole.

According to the drawings it has been indicated with (2) a portion of a sheet metal band with a series of incisions obtained by removing triangular circular (3) sheet metal parts (4) and rectangular (5) that perform a portion of a band succession of trapezoidal and rectangular segments (6) eventually with beveled and rounded edges, and in other portion a continuous band (7). Throughout the development length of the band (1) are folded lines (8), (9), (10) and (11).

Once the band is bent according to the lines bending, U-profiling is performed that has a wall vertical with continuous surface (7) and the other segmented with a succession of rectangular elements (6) connected to the other (7) by means of a succession of trapezoidal elements (5) which It forms a base surface. The bending lines (9) and (10) they constitute the extremities of the cantilever that a circular curvilinear section (12) or carved, while the line of folded (11) forms flaps at the top of the wings

A flat laminar element (13) constituted by a list or band preferably of metal whose dimension of minor side is less than the height of the wings (6) of the profiling to which it is connected and has the same thickness, is placed between the wings alternately between the inner surface of a alita e the outer surface of the next wing, connecting each wing and getting a wall virtually keep going.

The flat sheet element (13) is kept in position by the overhangs and by the flaps at the top of the wings (6), which form slides within the which can slide or pass the element (13).

The cantilever (12) is made, in succession alternated, to the base of a wing in correspondence of the line of folded (9) but not in the next wing. The folding or flap longitudinal (14) made in the upper part of the wing (6), bending the free end of the wing itself, it is oriented towards the external profiling while folding or longitudinal flap (15) in the next wing it is oriented towards the inner part of the profiled, in alternate succession. The bends or flaps Longitudinal (14) or (15) made at the top of each wing bending the free end of the wing itself may have a maximum inclination of 90 °. In a variant of this first form of embodiment of the present invention, the overhang (12) is realized alternatively in the outer surface of a wing and in the inner surface of the next wing.

The placement of the flat sheet element (13) is obtained by means of the overhangs (12) and the bends (14) and (15) at the top of the wings (6) that form slides within which you can slide the element. (13).

A further embodiment of the present invention consists of a particularly shaped profiling of the double C type, obtained by bending a sheet of metal preventively profiled or by symmetrical mounting of two sheets of metal preventively profiled to C and fixed by means of mechanical caulking or electric punching, each of the two laminar elements is constituted by a list or a band preferably of metal whose dimension of the smaller side is less than the height of the wings (16) of the profile to which it is connected and It has the same thickness and is placed between the wings (16), alternatively between the inner surface of a wing and the outer surface of the next wing, connecting each wing and getting two virtually continuous walls.

The placement of flat laminar elements (13 '') is obtained by combining a cantilever in bas-relief (17), performed in an alternate sequence on the face outer surface of a wing (16) distanced from the line of folded (18) but not in the next wing, and flaps constituted by a simple bending and flaps particularly shaped (19) at the top of the wings (16) bending to 90 ° the free end of the wings, which form some slides within which the elements slide (13``).

The overhang (17) can also be performed, alternatively both on the outer surface of a wing as in the inner surface of the next wing.

When the profiles are forced to take certain curvature or a series of curvatures, the laminar elements planes (13) or (13 '') that connect the wings respectively (6) and (16), to constitute virtually continuous walls, slide and at the same time therefore they flex, taking the same curvature that can be locked and maintained once the elements (13) or (13 '') are fixed by means of redouble or punch the respective wings (6) or (16). In practice in a first preferred embodiment of the present invention the longitudinal flat sheet element, preferably of the type conformed to U or C, it makes a sliding wall along the longitudinal direction of the profiling so that profiling is can fold and easily locked, by simply redouble or punch, to the curvature or to the series of curvatures conferred

In a second preferred embodiment the flat laminar elements with longitudinal development (13 '') a once associated with a special profile, preferably of the type conformed to double C, perform on segmented lower wings and along the longitudinal direction of the profiling a double virtual continuous wall and sliding or sliding so that the profiling can be folded and easily locked, by means of simply redouble or punch, to the curvature or series of conferred curvatures, with a marked increase in resistance and rigidity of the profiling obtained. The invention lends itself superbly in the realization of structural beams of support for panels and lastras of any shape or type, suitable for build a multiplicity of structures in forms too complex with remarkable speed and simplicity with obvious economic benefits.

The invention allows profiling particularly shaped, the realization and self maintenance of any type of curvatures or series of curvatures with simply redouble or with the punching of the wings that are like this more rigid and supportive.
