[0001] The present invention relates to a tower, in particular for supporting telecommunication
appliances, for example antennas.
[0002] The towers for supporting telecommunication appliances are substantially divided
into two categories, according to height: trestles, suitable for reaching high heights,
for example more than ten metres, and the simpler towers of tubular shape for smaller
height. The latter serve for example for supporting the antennas of shelters for telecommunication
appliances.
[0003] Precisely, towers consist of tubular elements of cylindrical or polygonal shape with
a few metres length. Despite their large thickness, more tubular elements must be
piled up on top of each to other to obtain sufficient heights. To do so, each tubular
element is provided with connecting flanges at the ends thereof that must necessarily
be made separately and then welded to the tubular body.
[0004] Moreover, each tubular element of the tower has a considerable weight, which requires
the use of a crane for handling thereof. Since these towers are mainly intended for
movable installations, the problem of the handiness and transportability thereof is
much felt.
[0005] A tower comprising all of the features of the preamble of claim 1 is known from document
AT-8-380511.
[0006] The object of the present invention is to propose a tower of the second type which
should allow obviating the disadvantages mentioned above with reference to the towers
used so far.
[0007] In particular, the object of the present invention is to propose a tower which should
allow reaching much higher heights and which should be at the same time much lighter,
much easier to made and assemble and much handier and more convenient to carry and
store.
[0008] Such objects are achieved with a tower according to claim 1.
[0009] The details and the advantages of the tower according to the present invention will

[0010] In accordance with a general embodiment, tower 1; 100 according to the present invention
comprises a plurality of bars 10; 110 next to one another along the respective sides
so as to make a hollow structure of tubular shape and with polygonal section.
[0011] Each bar comprises a bar body 11; 111 defining at least one side or face of said
structure of tubular shape and longitudinal coupling appendices 12; 112 inclined relative
to said bar body so that adjacent appendices of two sided bars are facing and fixed
to each other.
[0012] In other words, tower 1; 100 comprises of a plurality of bars or panels of oblong
shape that extend along a direction substantially parallel to the longitudinal axis
of the tower and that are connected to one another along the respective sides.
[0013] Said sides of the bars or panels are defined by the coupling appendices 12; 112.
These are shaped as tongues or ribs that preferably extend along all the side of bar
10; 110 and that have a smaller cross extension compared to the cross extension of
the bar body.
[0014] According to a preferred embodiment, bars 10; 110 are equal to each other so as to
make an equilateral polygon section structure.
[0015] Preferably, the coupling appendices 12; 112 are inclined outwards of the parallelepiped
structure, and in particular they extend beyond the perimeter formed by the bar sides.
[0016] In other words, the coupling appendices 12; 112 extend from the vertices of the polygon
formed by the bar bodies, in radial direction relative to the centre of said polygon.
[0017] According a particularly advantageous embodiment, bars 10; 110 are obtained from
sheared and bent sheets.
[0018] According to an embodiment, the coupling appendices 12; 112 carry a plurality of
threaded holes 13; 113 distributed along the longitudinal extension thereof so as
to be fixed to each other by bolts 14; 114.
[0019] According to an embodiment illustrated in figures 1-14, the tower comprises two sections
or modules 1', 1" superimposed in height to one another, each section consisting of
a single order of bars 10 fixed to one another along the sides. Superimposed sections
are connected to one another by connecting plates 16 that connect the adjacent ends
of at least two coupling appendices of two superimposed bars to each other. For example
each bar, and thus a section, has a height of about three metres.
[0020] Preferably, the connecting plates 16 are bolted to the coupling appendices 12.
[0021] Advantageously, the connecting plates 16 are also bolted to the bar bodies 11 of
two superimposed bars. In the practice, each connecting plate 16 has an L shape with
angle equal to that formed by the coupling appendices 12 relative to the bar body
11, so as to overlap both to a portion of the body and to the appendix, without protruding
therefrom. Each bar body 11 therefore has, at the top and bottom ends thereof, and
in the proximity of the coupling appendices 12, a plurality of holes 11', for example
three holes, with which as many holes 16' obtained in the corresponding portion of
the connecting plate 16 are aligned. Also the coupling appendices 12 are crossed at
the ends thereof by a plurality of holes 12', for example three holes, with which
as many holes 16" obtained in the corresponding portion of plate 16 are aligned. Advantageously,
the two orders of holes in the bar body and in the coupling appendices are staggered
in height so as to not generate weakening of the tower structure.
[0022] According to an embodiment that comprises multiple superimposed sections, for example
up to exceeding 20-30 metres height, the tower comprises a lower portion 2, for example
comprising three or four sections 1', 1", ..., of truncated-pyramid shape in order
to improve the stability of the structure.
[0023] Advantageously, such shape is obtained with the use of bars 10' of trapezoidal shape,
that is, that narrow upwards (figures 6, 6a, 8, 8a).
[0024] Moreover, the bars of the higher sections have a smaller thickness than the bars
of the lower sections, so as to impart greater lightness to the structure as the tower
height increases.
[0025] In accordance with an embodiment illustrated in figures 1-14, each section of the
tower comprises eight bars 10, 10' side by side to make an octagonal structure. Thus,
each bar comprises a flat bar body 11 that defines, in cross section, the side or
face of an octagon.
[0026] In one embodiment illustrated in figures 15-20, each section of the tower comprises
three bars 100 side by side and fixed to each other. Each bar 100 comprises, besides
the coupling appendices 112, a bar body 111 bent as a V with internal angle of 120°,
so that the three bars side by side make a hexagonal structure. In other words, each
bar body 111 has a median bending line that defines a pair of adjacent sides or faces
of the hexagonal structure.
[0027] Such embodiment is particularly suitable for constructing a tower 100 in a single
section, for example with height equal to about 10 metres.
[0028] In one embodiment particularly suitable for large height towers, bars 10 of the bottom
section rest on a base flange 18 anchored to a foundation 17, for example of concrete.
Preferably, the bottom ends of bars 10 are fixed to flange 18 by square plates 19
bolted both to the bar bodies 11 and to flange 18.
[0029] Figures 8, 8a show the bottom bars 10' of the tower at the base whereof there is
obtained a plurality of holes 11" to which as many holes 19' obtained in the square
plates 19 are obtained.
[0030] According to one embodiment, flange 18 consists of four circular crown sectors 18'
side by side. Each square plate 19 exhibits at least one pair of threaded holes 20
so that adjacent sectors 18' of flange 18 are connected to each other by a square
plate 19 that overlaps to the contiguous ends of said sectors.
[0031] The base flange 18 is in turn anchored to the foundation by log bolts 22. Advantageously,
log bolts 22 emerge from the foundation so that the locking nuts 22' of log bolts
22 secure not only flange 18 but also the square plates 19 to the flange itself.
[0032] According to one embodiment particularly suitable for smaller size towers, for example
the hexagonal tower described above, tower 100 is supported by inclined props 120
resting on the ground. In particular, the top ends 120' of the props are fixed, for
example by bolts, to the coupling appendices 112 of adjacent bars. The bottom ends
120" resting on the ground may also be fixed to the tower base by respective horizontal
crosspieces 121.
[0033] In this embodiment, therefore, the tower does not need the construction of a ground
anchoring foundation but it is simply resting on the ground and supported by props
120 and crosspieces 121.
[0034] According to one embodiment, a rack 30 for cable support and guide is fixed to at
least two coupling appendices side by side 12; 112 of adjacent bars. In particular,
rack 30 comprises a plurality of brackets 31 that extend overhanging by the full tower
height and that may be fixed to the appendices 12; 112 by bolts.
[0035] At least one rod 40 for supporting an antenna or other telecommunication appliance
is anchored, for example by bolted brackets, in the proximity of the top of tower
1; 100.
[0036] Moreover, a rung ladder 50 is fixed to at least two coupling appendices side by side
12; 112 of adjacent bars.
[0037] According to one embodiment particularly suitable for large height and thus large
section towers 1, ladder 50 comprises a plurality of anchoring plates 51 that extend
overhanging from coupling appendices 12, to which plates 51 are advantageously fixed
by bolts. Each plate 51 is crossed by at least one threaded hole wherein at last one
rung 52 of ladder 50 screws. Thus, the rung ladder 50 is assembled straight on the
tower itself, which acts as bearing element thereof.
[0038] In one embodiment particularly suitable for smaller size towers 100, on the other
hand, ladder 150 is a traditional resting ladder, at least one vertical upright of
which it can be advantageously anchored, for example by special brackets 151, to the
coupling appendices 112.
[0039] Advantageously, moreover, each bar 10; 110 has at least a vertical row of lightening
windows 60; 160 obtained in the bar body 11; 111.
[0040] Preferably, the rows of window of two adjacent bars are staggered in height so that
at the window of a bar, the other bar has a completely solid portion, that is, without
window.
[0041] In all the embodiments described, the tower is completely without welds, so the galvanisation
of the metal making up all the tower elements is free from discontinuity. The structure
therefore has no weakening zones or flaws.
[0042] The modular structure essentially consisting of shaped bars allows an installation
of the tower without the use of special means like cranes or large motor vehicles.
In particular, thanks to the lightness of the bars, the tower can be manually mounted
even by few operators using simple pulleys for bringing the bars to the desired height.
[0043] Thanks to the possibility of piling all the elements making up the tower, storage
and transport thereof are facilitated and allowed even in very narrow spaces.
[0044] It should be noted that the tower proposed allows reaching heights comparable to
those of trestles, while having a much simpler structure, consisting of a considerably
smaller number of parts and much easier to carry and store.
[0045] Finally, it should be noted that the tower according to the invention is not only
suitable to be used in the field of telecommunications but it may be used also as
support for wind appliances or in the building field.
