Definitions
- the present invention relates to a modular joint for light metal structures such as raised platforms, large-size shelving and storage frames.
- Structures of the abovementioned type which are essentially formed by vertical load-bearing uprights or columns which are rigidly connected to substantially horizontal beams so as to form a reticular support structure for walkways, roofs, raised surfaces or the like are known.
- connections between the columns and the beams, as well as between the latter, are generally performed by means of welded joints or, more commonly, are bolted so as to allow the assembly thereof in situ without the need for specialised labour.
- Italian patent IT-A-1 267679 discloses a raised-platform structure comprising vertical load-bearing columns which support a flat frame formed by main and secondary beams on which a walkway rests.
- the top of each column has, welded to it, a flange with, fixed to it, a joint or "capital" formed by a first horizontal plate which is provided with holes for the bolts for connection to the flange of the column and to which a pair of mutually perpendicular vertical plates is welded.
- the vertical plates have, welded to them, a second horizontal plate along the edges of which the ends of the horizontal beams are positioned.
- This constructional form of the capital joint is suitable for the connection of corner structures, with beams positioned on two adjacent sides of the joint.
- connecting devices in the form of L-shaped rectangular plates of a type known per se are envisaged.
- the beams are formed by pairs of sections with a sigma-shaped cross-section, which are mutually facing and have flat surface zones provided with holes for receiving bolts for connection to the vertical plates - also perfectly flat - of the capital joints.
- a further drawback consists in that the connection between the beams and the plates of the capital joints is substantially of the "hinge” type, owing to the fact that the surfaces for connection of the beams and the vertical plates of the joints are substantially flat and mutually joined together solely by means of friction and therefore do not allow interlocking moments to be transmitted.
- the "hinge type” connection of the joints to the horizontal beams produces on these latter high sag (deflection) forces which increase further and may be excessive when the horizontal beams are loaded with constructional elements such as panels for the walkways or brackets.
- the beams must be reinforced at the point of connection with the uprights, with consequent greater costs and complexity of the structure.
- a main object of the present invention is to eliminate the drawbacks mentioned above, providing a modular joint for the connection of vertical uprights and horizontal beams having characteristics of high flexibility and reliability at a low cost.
- a particular object is that of providing a modular joint which can be used for all reticular structures with two or more horizontal beams connected to each side of the upright without modifications or additions.
- Another particular object is that of providing a modular joint with a simplified and robust structure, able to guarantee a considerable dimensional stability of the raised floor structure or the like, while keeping the sag (deflection) of the beams within low values.
- a further object is that of providing a modular joint which allows a balustrade structure to be fitted at an extremely low cost.
- Yet another object is that of designing a modular joint which has a compact configuration without projections so as to be aesthetically pleasing.
- each upright comprises a hollow section with flat side walls and with an open top end
- each beam comprises a pair of mutually facing sections with substantially flat central cores, characterized in that it comprises a locking element which can be slidably inserted into the open end of a corresponding upright and is provided with connecting members for releasable connection to at least one horizontal beam along each of the side walls of the upright.
- the modular joint thus obtained may be used for all reticular structures with two or more horizontal beams connected to each side of the upright without modifications or additions.
- the simplified and robust configuration of the joint ensures a notable dimensional stability of the structure, keeping the sag (deflection) of the beams within low values.
- Fig. 1 shows a general perspective view of a metal structure which uses a series of modular joints according to the invention
- Fig. 2 shows a perspective view of a detail of a modular joint according to Fig. 1 on a larger scale
- Fig. 3 shows a perspective view of the detail according to Fig. 2 during insertion into an upright of the structure
- Fig. 4 shows a perspective view of the detail according to Fig. 2 inserted into the upright;
- Fig. 5 shows a perspective view of another detail of the joint according to Fig. 1 on a larger scale
- Fig. 6 shows a perspective view of the detail according to Fig. 5 during joining to an upright of the structure
- Fig. 7 shows a perspective view of the detail according to Fig. 5 joined to the upright;
- Fig. 8 shows a perspective view of the detail according to Fig. 5 during joining to a beam of the structure
- Fig. 9 shows a perspective view of the detail according to Fig. 5 joined to a beam and to an upright;
- Fig. 1 0 shows a cross-sectional view of the joint according to the invention sectioned along a horizontal plane
- Fig. 1 1 shows a cross-sectional view of the joint according to Fig. 1 0 sectioned along the vertical plane indicated by the line XI-XI;
- Fig. 1 2 shows a perspective view of a portion of the structure according to Fig. 1 to which a section of a balustrade has been joined;
- Fig. 1 3 shows an exploded perspective view of the balustrade structure according to Fig. 1 2.
- a metal reticular structure generally indicated S, of the type used for the construction of raised platforms or raised storage frames is illustrated.
- the structure S essentially consists of a series of uprights M which are substantially vertical and which support a flat frame formed by a plurality of substantially horizontal beams T arranged along the periphery and inside the frame itself.
- each upright M has a main body consisting of a hollow section portion, with a square or in any case polygonal cross-section and with flat side walls, provided at the bottom end thereof with a flange F for fixing to the ground and an open top end.
- Each beam T which is also of a per se known type, consists of a pair of pressed or profiled plates P with a substantially C-shaped cross-section, as can be seen more clearly in Figures 8 and 9, which face each other and have vertical cores A which are substantially parallel and slightly reciprocally spaced in the transverse direction.
- the cores A have, formed along them, a first series of larger size holes for receiving cables, pipes and other devices, and a second series of smaller-diameter holes for connection to other beams and to the uprights M.
- the uprights M are connected to the beams T by means of a series of joints which are each denoted by the reference numeral 1 .
- each joint 1 comprises a locking element 2 which can be slidably inserted into the open end of an upright M and is provided with connecting members for releasable connection to at least one beam T along each of the side walls of the upright.
- the locking element 2 consists of a tubular body with a substantially square or polygonal shaped cross-section matching that of the , internal cavity of the upright M.
- the tubular body of the locking element 2 is obtained by the union of vertical side walls 3 welded along the edges thereof and having preferably an average thickness greater than that of the side walls of the uprights M.
- a longitudinal end of the tubular body has, fixed thereto, a flat closing flange
- the flange 4 which has a shape, in plan view, the same as the cross-section of the upright, so as to have a peripheral edge projecting with respect to that of the tubular body.
- the flange 4 may have threaded circular holes 5 and oblong holes 6.
- each locking element 2 may be inserted into the internal cavity of a respective upright M, inserting into the oblong holes 6 special pins of an extractor, not shown in the drawings. Moreover, its projecting peripheral edge may come into abutment against the free top edge of the upright prior to connection with the beams T.
- all the side walls 3 of the tubular body have a plurality of threaded holes 7 corresponding to smooth through-holes 8 formed in registered positions over all the external surfaces of the upright M in the vicinity of its open top end.
- the connecting members of the joint 1 also comprise, along each side of the upright, an interface surface, generally indicated by the reference numeral 9, which is essentially T-shaped and intended to be housed between the cores A of each beam T.
- Each interface element 9 is essentially formed by a substantially vertical flat flange 1 0 to which at least one and preferably two specular plates 1 1 - which are also substantially vertical and perpendicular to the flange 1 0 and separated by spacers 1 2 - is/are connected.
- the flange 1 0 has a plurality of through-holes 1 3 in registration with the holes 8 of the upright for insertion of bolts, not shown in the drawings, intended to be screwed into the said threaded holes 7 formed in the locking element 2.
- Each vertical plate 1 1 has a series of holes 1 4 for receiving connecting screws - not shown in the drawings - inserted into corresponding holes 1 5 formed in the cores A of the beams T.
- each plate 1 1 has formed thereon at least one horizontal linear projection 1 6 which is intended to engage into a corresponding groove 1 7 of matching shape formed in each core A of a beam T.
- connection between each upright and a beam will not be of the "hinge” type, but will tend to be of the "interlocking” type so as to reduce considerably the sag (deflection) of the said beam.
- balustrade structure 1 8 In order to fix a balustrade structure 1 8 to the load-bearing frame of the beams T, it is possible to secure vertical uprights 1 9 to the closing flange 4 owing to the presence therein of threaded holes 5 on the flange 4 of the locking element 2.
- the horizontal rail sections 20 and the retaining panels 21 may be fixed onto the uprights 1 9, thus ensuring the necessary safety and stability.
- the joint according to the invention allows to modify and expand easily the raised platform structures without removing and replacing the existing joints with others of a different type.
