FIELD OF THE INVENTION
[0001] The present invention concerns a pillar for building constructions, such as for example
a building, a bridge, a viaduct, a multi-storey car park or other. The present invention
also concerns a structural node consisting of said pillar and one or more horizontal
structural elements structurally associated therewith. In particular, the pillar is
provided with at least a connection member which allows to connect to the pillar a
horizontal structural element, and thus defines a structural node. The structural
node is constituted by positioning specific support means of the beam in correspondence
with the connection means of the pillar, so as to determine a structural continuity
of the pillar and the beam.
BACKGROUND OF THE INVENTION
[0002] It is known in building constructions to make pillars, including pre-fabricated pillars,
of the self-bearing type consisting of a plurality of parts or modules, which can
even be several tens of meters long, and which are connected to each other by means
of connection members so as to guarantee structural continuity thereof.
[0003] In this known solution, to every connection member a supporting plate is attached,
protruding from the bulk of the relative part or module, and able to support one or
more horizontal structural elements, such as floor beams and/or roof beams of the
construction.
[0004] In this way, a structural node is defined between the two bearing elements, that
is, the formed pillar and the beams, so as to achieve a structural continuity between
them.
[0005] Although this known solution promotes easy and safe installation of the bearing elements,
it has the disadvantage that it provides a structural node between the pillar and
the beam in which, due to the protrusion of the supporting plate from the bulk of
the relative part or module, there is no real and proper interconnection of the pillar
and beam, since the latter remains outside the pillar although it is physically connected
to it.
[0006] One purpose of the present invention is therefore to achieve a pillar for building
constructions which not only guarantees a stable and safe interconnection of the parts
or modules of which it is made, but also allows to rest the relative beams, or other
horizontal structural elements, inside its bulk.
[0007] Another purpose of the present invention is to achieve a structural node between
the pillar and beam which is simple and economical to make, and which allows to physically
interconnect the pillar and beam, increasing the structural solidity of the building
construction thus made.
[0008] The Applicant has devised, tested and embodied the present invention to overcome
the shortcomings of the state of the art and to obtain these and other purposes and
advantages.
SUMMARY OF THE INVENTION
[0009] The present invention is set forth and characterized in the independent claims, while
the dependent claims describe other characteristics of the invention or variants to
the main inventive idea.
[0010] In accordance with the above purposes, a connection pillar according to the present
invention is applied in the making of building constructions and comprises at least
a metal reinforcement, possibly incorporated in a concrete mix, and provided with
connection means able to define a structural node by means of connection to one or
more horizontal structural elements.
[0011] According to a first characteristic feature of the present invention, the connection
means comprises at least a horizontal metal plate solid with said metal reinforcement
and from which two metal uprights, protruding with respect to said metal reinforcement,
branch off vertically, and which define at least an abutment surface for the positioning
of the horizontal structural element, and allow to coaxially connect the pillar with
an analogous pillar, guaranteeing structural continuity between the two.
[0012] According to another characteristic feature of the present invention, the two metal
uprights are substantially parallel to each other and offset with respect to a median
transverse plane passing through the center line of the metal plate, so as to define
two supporting zones, substantially inside the transverse bulk of the pillar, in each
of which one of said horizontal structural elements is able to rest.
[0013] In this way, the horizontal structural elements can cooperate directly with the connection
means inside the bulk of the pillar, thus defining a proper interconnection between
the pillar and beam.
[0014] With the present invention we therefore have a considerable improvement to the structural
resistance of the building construction achieved, but in any case maintaining an easy
and safe installation of the parts.
[0015] In a preferential form of embodiment, the metal uprights define respective reference
surfaces able to determine the correct positioning of the horizontal structural elements
in the supporting zones.
[0016] According to another preferential form of embodiment, the pillar comprises two metal
plates, respectively first and second, disposed solid on opposite sides with respect
to the metal reinforcement and each provided with respective first and second metal
uprights.
[0017] In particular, the first metal uprights comprise two first metal blocks disposed
parallel, distanced and offset to each other with respect to the transverse plane
passing through the center line of the first plate; while the second metal uprights
comprise two pairs of second metal blocks, in which the two pairs of second blocks
are disposed parallel, distanced and offset to each other with respect to the transverse
plane passing through the center line of the second plate, and in which every pair
of second metal blocks defines a housing seating able to house, in the assembled condition,
the first metal blocks of the first metal uprights.
[0018] In this way, two analogous pillars according to the present invention can be coupled
coaxially together stably and safely, ensuring reciprocal structural continuity.
[0019] Furthermore, each horizontal structural element comprises an end having at least
a protruding portion and provided with a first abutment surface able to cooperate
with a corresponding first reference surface defined by the metal uprights, so as
to determine a first positioning of the horizontal structural element in the supporting
zone defined by the metal uprights in a first direction, and a second abutment surface
able to cooperate with a corresponding second reference surface defined by the connection
means, so as to determine a second positioning of the horizontal structural element
in the supporting zone in a second direction, substantially inclined with respect
to the first direction.
[0020] Advantageously, the first reference surface and the second reference surface are
substantially perpendicular to each other.

DETAILED DESCRIPTION OF SOME PREFERENTIAL FORMS OF EMBODIMENT
[0022] A connection node 10 and a pillar 11, only partly illustrated, according to the present
invention, can be seen in the attached drawings.
[0023] In particular, the connection node 10 is applied to reciprocally connect, with structural
continuity, the pillar 11 and at least a beam 12, in this case two aligned with each
other, in a building construction, such as for example a building, a bridge, a viaduct
or other.
[0024] However, it cannot be excluded that instead of the beam 12 any other known horizontal
structural element can be provided.
[0025] In particular, the pillar 11 substantially consists of a plurality of modules, in
this case a lower module 43 and an upper module 15, connected by means of a connection
member 16, while the two beams 12 are for example of the type known in the market
under the trade name REP®.
[0026] To simplify the description, hereafter we shall refer specifically to a pillar 11
made with only two modules 43 and 15, but it cannot be excluded that every pillar
11 can consist of a desired number of modules until the specific planned heights of
the building construction are reached.
[0027] In the form of embodiment shown in figs. 1 to 3, each module 43 or 15 has a transverse
shape substantially rounded on the opposite sides and, for example, can be of the
type formed by a metal tubular element inside which, in a known manner, concrete or
other filler material is disposed, reinforced by means of specific rods or reinforcement
cages 14.
[0028] Alternatively, each module 43 or 15 can preferably be made of centrifuged reinforced
concrete, or vibrated reinforced concrete.
[0029] According to the variant embodiments shown in figs. 4a and 4b, the modules 43 and
15 that form the pillars 11 have a cross section of a different geometric shape from
that of fig. 1, for example quadrangular (fig. 4a), or circular (fig. 4b), or other
shapes depending on the various aesthetic or operational requirements.
[0030] The connection node 10 according to the present invention comprises on one side the
connection member 16 between the two modules 43, 15 of the pillar 11 and, on the other
side, a respective end plate 18, associated with each of the two beams 12.
[0031] In this case, the connection member 16 comprises a lower plate 17 welded directly
to the reinforcements 14 of the lower module 43, and from which two coupling blocks
19 extend vertically, and an upper plate 20 welded directly to the reinforcements
14 of the upper module 15 and from which two coupling blocks 21 extend vertically.
[0032] Alternatively, the lower plate 17 and the upper plate 19, instead of being welded,
are made solid with the respective reinforcements 14 of the modules 43 and 15 by means
of bolts, bushings or other.
[0033] In particular, the coupling blocks 19 constitute the male element of the connection
member 16 and are substantially parallel to each other and offset with respect to
a median transverse plane passing through the centerline of the lower plate 17. The
two pairs of coupling blocks 21 constitute instead the female element of the connection
member 16 and each of them consists, precisely, of two metal blocks 21, disposed parallel
and separate so as to define a housing seating 33 able to house a relative one of
the coupling blocks 19 of the lower plate 17. The assembly of the coupling blocks
19 and the pairs of coupling blocks 21 is consolidated in this case by means of bolts.
[0034] The two coupling blocks 19 and the two relative pairs of blocks 21 form two relative
assembled elements, respectively a first 24 and a second 28, separated and parallel
so as to define between them a housing interstice 22, two relative front reference
surfaces 23 and two relative lateral reference surfaces 25. In particular, each assembled
element 24 or 28 defines a front reference surface 23 and a lateral reference surface
25, each lying on relative planes substantially orthogonal to each other.
[0035] According to another form of embodiment, shown in fig. 6, in the case of prefabricated
multi-plane modules the connection member 16 is made with only the two blocks 19 offset,
solidly attached, for example by welding, on both sides to the lower plate 17 and
the upper plate 20.
[0036] Each end plate 18 is attached axially to the relative beam 12, and has a protruding
portion 26 which protrudes frontally from the bulk of the beam 12, and is able to
be positioned in the housing interstice 22 defined between the two assembled elements
24 and 28 of the connection member 16.
[0037] In particular, the protruding portion 26 comprises a first fin 27 extending laterally
and having at the front an abutment surface 29 able to be positioned in contact with
a relative first frontal reference surface 23, so as to define the positioning of
the beam 12 with respect to the pillar 11 in a first direction substantially radial
to the pillar 11, and to prevent the accidental lateral tilting of the beam 12.
[0038] The protruding portion 26 also comprises a second fin 30 extending laterally and
having on the side a supporting surface 31 able to be positioned resting against a
relative lateral reference surface, so as to define the positioning of the beam 12
with respect to the pillar 11 in a second direction substantially orthogonal to said
first radial direction.
[0039] Once the connection node 10 has been constituted in this way, we have a real and
proper physical interconnection of the pillar 11 and the relative beams 12, so as
to guarantee maximum structural continuity and mechanical resistance to stress of
the construction thus achieved.
[0040] As shown in the attached drawings, in this case, the connection node 10 also comprises
two lateral reinforcement elements 32 which have their respective ends disposed in
association with the two beams 12, laterally to the respective end plates 18, and
pass through the connection member 16 passing laterally to the two assembled elements
24 and 28. The lateral reinforcement elements 32 thus define a structural continuity
and reinforcement between the two beams 12 and also between the beams 12 and the pillar
11.
[0041] In particular, in the form of embodiment shown in figs. 1, 2, 3, 4a and 4b, each
of the lateral reinforcement elements 32 consists of a straight metal bar 32a.
[0042] In the variant shown in fig. 5a, the metal bar 32a which makes up the lateral reinforcement
elements 32 has its ends bent upwards by about 90°.
[0043] In the variants shown in figs. 5b and 5c, each of the lateral reinforcement elements
32 consists of two metal bars 32a, each attached to an anchoring blade 32b incorporated
and welded inside the relative beam 12.
[0044] In the variant shown in fig. 5d, each of the lateral reinforcement elements 32 consists
of two metal bars 32a.
[0045] It is clear, however, that modifications and/or additions of parts may be made to
the connection node 10 and the pillar 11 as described heretofore, without departing
from the field and scope of the present invention.
[0046] It is also clear that, although the present invention has been described with reference
to specific examples, a person of skill in the art shall certainly be able to achieve
many other equivalent forms of pillar for building constructions and structural node
