[0001] The present patent application for industrial invention relates to a metal upright
used to obtain bearing frames for prefabricated modular partition walls.
[0002] The upright of the invention is designed to be used to build partition walls of the
type formed of a bearing frame covered on both sides by panels of any type of material.
[0003] The bearing frame is composed of a sequence of uprights, in which a series of slots
is provided to act as fixing points for the support hook bolts of the horizontal beams
used to make the transversal connection between two adjacent uprights.
[0004] The said frames are then provided with covering panels supported by suitable brackets
fixed to the upright by means of the series of slots.
[0005] Uprights are currently made of press-folded metal sheet and provided with tubular
structure, with transversal rectangular or square section, with the four square-cut
inwards-folded corners in such a way that their 90° concave angle faces the external
of the upright.
[0006] A series of regularly spaced identical shaped slots is obtained on the corners, extending
astride the two L-shaped wings that border the inwards-folded corners.
[0007] The slots act as fixing points for the beam-supporting hook bolts or for the brackets
that support the covering panels.
[0008] The design of prefabricated modular walls aims at giving the finished product high
strength and rigidity, as well as good sound insulation properties.
[0009] The poor sound insulation capacity of the metal sheet uprights that are currently
used to obtain the said walls, however, impairs the sound insulation that is normally
obtained by filling the partition wall with sound proof materials.
[0010] Moreover, the structural configuration of the said uprights must be studied in such
a way that the partition wall can withstand as much as possible the transversal pressures
that are discharged on it, such as accidental shocks against the wall or the weight
of a person leaning on it.
[0011] The purpose of the present invention is to provide an upright used to obtain bearing
frames for prefabricated modular partition walls that, without altering the structural
configuration of the frame, is able to give higher rigidity to the entire partition
wall.
[0012] Another purpose of the present invention is to provide an upright used to obtain
bearing frames for prefabricated modular partition walls provided with good sound
proof properties because of its innovative structural configuration.
[0013] These and other purposes have been achieved with the upright of the invention, whose
main characteristics are illustrated in the first claim.
[0014] The upright of the invention is composed of two specularly opposite identical bodies
with tubular structure connected by a central element.
[0015] The upright has a transversal double-T section, in which the horizontal parallel
wings are box-shaped.
[0016] Each box-shaped wing has a basically rectangular section with a pair of sides, a
right-hand side and a left-hand side, and a pair of lateral sides, an external side
and an internal side.
[0017] The internal side is designed to be opposed and connected to the corresponding internal
side of the other identical box-shaped wing by means of the said central element.
[0018] The two corners at the two ends of the external side of each tubular body are L-folded
inwards and a series of regularly-spaced identical slots is obtained on the said folded
corners, extending astride the two wings that border each L-shaped corner.
[0019] The series of slots is used as fixed points for the beam-supporting hook bolts or
for the ordinary brackets used to support the covering panels.
[0020] The upright of the invention is therefore provided with two external sides and two
internal sides, all parallel, which represent four sound-proof barriers, unlike the
uprights that are currently available on the market, which are provided with only
two sound-proof barriers on the external sides.
[0021] The frame obtained with the upright of the invention is much more rigid than the
ones that are currently available, since its double-T structure with box-shaped wings
ensures great strength and high resistance to transversal pressure.
[0022] For major clarity the description of the metal upright according to the present invention
continues with reference to the enclosed drawings, which are intended for purposes
of illustration only and not in a limiting sense, whereby:
- figure 1 is a top view of the upright of the invention;
- figure 2 is a perspective sectional view of the upright of the invention;
- figure 3 is a view of the upright of the invention provided with ordinary brackets
to
support covering panels and with beam-supporting hook bolts;
- figure 4 is an exploded view of figure 3.
[0023] With reference to figures 1 and 2, the upright (M) of the invention has a double-T
section, in which the horizontal parallel wings (1) are box-shaped and composed of
two opposite symmetrical bodies with basically rectangular tubular structure connected
with a central element (2).
[0024] Each box-shaped wing (1) is composed of a pair of sides (1 a), an external side (1b)
and an internal side (1 c), which is opposed and connected to the corresponding internal
side (1 c) of the other identical box-shaped wing (1) by means of the central element
(2).
[0025] The external side (1b) is shorter than the internal side (1c) and the transversal
side (1a) used for connection is folded inwards.
[0026] As shown in fig. 1, the transversal side (1a) includes a first section (1d) adjacent
to the internal side (1c) and a second section (1e) adjacent to the external side
(1b) that are square-connected with a short intermediate section (1f).
[0027] Each transversal side (1a) is provided with a series of regularly-spaced identical
slots (3), as shown in fig. 2.
[0028] Each slot (3) entirely covers the intermediate section (1 f) and a small part of
the sections (1 d and 1 e) adjacent to it.
[0029] As shown in figs. 3 and 4, the slots (3) act as fixing points for ordinary hook bolts
(C) used to support the connection beams (B) between adjacent uprights (M), or for
ordinary brackets (S) used to support covering panels, which are not shown in the
figure for convenience purposes.
[0030] Each hook bolt (C) has catches (4) for fixing to the upright (M), designed to be
inserted inside the slots (3) and teeth (5) for fixing and centring of the connection
beams (B) that are provided with corresponding slots (5a) designed to be coupled with
the teeth (5).
[0031] Each bracket (S) has hooks (6) designed to be inserted inside the slots (3) and holes
(7) for the insertion of the screws designed to fix the said brackets on the back
of the panels.
[0032] According to a preferred constructive embodiment, the upright (M) is obtained by
folding a flat metal sheet, which is folded over and closed with hammering (2a) on
the central element (2), as shown in fig. 1.
[0033] According to an alternative constructive embodiment, the upright (M) is obtained
with pressing from a single piece of metal material.
