[0001] The invention refers to a system which permits to carry out metal barriers exclusively
by means of restraining composition. The invention, which avoids the necessity of
boring the components, can be used in the metal structur in general and particularly
for those in anodized aluminium.
[0002] For composing barriers, at present each component is blocked by means of through
screws and nuts; boring causes the weaken ing of the aluminium structure, an irksome
mounting work, as well as the necessity of employing skilled workers. To which it
is to add that the connection of anodized aluminium structu res requires special screws
in stainless steel. This mounting procedure turns out to be very limiting for the
employ of ano dized aluminium in the building industry on account of the costs and
of the required worker skill. The connection of the parts, in fact, if carried out
through other fixing means, would cause burr to the aluminium parts.
[0003] The invented method enables the integral solution of the problem by adopting a modular
system to be carried out exclusive ly by means of restraining the components. The
system employs three orders of components: a pair of profiled girders A and B, to
be employed in parallel, the shaped unions C and D which complete the structure and
are stablized between the spacers E. The barrier can be composed by inserting on the
longitudinal guides of the sections set up in parallel, the end parts properly prepared
in advance of the shaped unions, bringing them into restraining position, and then
by fitting the spacers and so on in a modular prosecution.
[0004] Forms of execution are supplied in a merely indicative way with the drawings of Tables
1 and 2, where Fig. 1 is the view of the upper girder, which operates also as handrail,
and Fig. 2 is a view of the lower girder. From the two figures, the central gui des
can be noted which are used for setting up the shaped unions. Fig. 3 is the cross
section of a spacer, while Fig. 4 is the view of an upper girder with a shaped unio
fitted on it which can be observed in its end part. Fig. 5 is the view of a composition
part with straight unions employing all system parts. Fig. 6 is a front view of a
composition as seen in Fig. 5. Fig. 7 of Table 2 is the cross section of the upper
girder, with a union fitted on the stabilization spacer of the projecting type, that
can be noted in the terminal. Fig. 8 is the perspective view of the spa cer to employ
for the condition of Fig. 7. Fig. 9 is the compose tion perspective view employing
projecting shaped unions. The use of spacers can be noted as shown in Fig. 8. Fig.
10 is the front view of the composition as per Fig. 9. Fig. 11 is a view of the particular
of a plate fitted in addition for blocking the compose tion at the angle posts.
[0005] The straight unions show a flat structure 1c with symmetrical recessings 2c and end
parts 3c for allowing the binding condition. The upper girder (A) shows a convex envelope
1a acting as handrail with symmetrical recessing 2a and lower flat parts 3a with a
central slit 4a determined by the inner lap 5a of the borders. The lower profile (B)
presents shape 1b with a square base and central slit 2b determined by the inside
lap of borders 3b. Distance piece (E) function is to stabilize the shaped unions of
type (C) or (D), at the distance fixed in advance, by blocking them in their seats.
It is characterized by plate 1e with central restraining part 2e which is inserted
into the guide in a balanced condition through the pair of lugs 3e and 4e. The spacer
shows an inner straight recessing for fitting a screw to fix an end plate for blocking
the angle posts when the composition has been completed.
[0006] For mounting a flat barrier, the pair of horizontal parallel girders (A) and (B)
are at first fitted on the angle post; then a pair of spacers is applied, and subsequently
a fillet of type (C) and so on until the structure is completed. The set of flat fillets
will be stabilized in the guides 4a and 2b by means of spacers. The intermediate connection
between the unions (C) in particular can be executed by means clamp connectors 1 to
be fitted and blocked in different ways.
[0007] For mounting projecting barriers, the stabilization of unions (D) on the terminals
has been foreseen by means of binding seats on the spacers to obtain by composing
the half recesses 5e. The projecting fillet 1d shows shaped end parts with curv ing
2d which act by retaining when unbinding. For the composi tion, the pair of distance
pieces (E) is at first inserted, by fitting end parts 2d afterwards into the pair
of slits 5e and by completing the binding condition by inserting the subsequent spacer
pair. As the structure is completed, it can be blocked on the head distance piece
by means of a screw for fixing a blocking plate to the angle post the barrier.
[0008] The shape of all system components may change according to the requirements of the
design.
[0009] The materials, the fixing elements and the completing ones may be foreseen in different
ways.
