Definitions

  • the present invention relates to an assembly of elements making up a modular joint by means of which to interconnect the struts of suspended structures, comprising
  • a first solution (GB-A-2150998), outlined as in the preamble to claim 1 considers that the longitudinal elements provided for the coupling for the multiple coupling element are equipped with spherical tips rotatably associable with the cavities of the multiple coupling elements themselves.
  • a structure erected utilizing this hinged type of arrangement undoubtedly lacks the general stability of a structure with rigid connectors.
  • a second type of construction technique, described in document (FR-A-864668), designed to overcome such drawbacks employs structural joints of prefabricated and positively coupled design, in which the joints are coupled by means of which the struts are connected with their axes disposed along directions predetermined by the embodiment of the coupling elements themselves.
  • a further drawback of the above solution is represented by the fact that it provides structural joints wherein the fixing efficiency is secured not by a special geometrical conformation, but by the intensity of the locking forces applied on it.
  • a third known solution demonstrated in FR-A-2591251, discloses a multiple coupling element equipped with shaped slots in which the tips of the longitudinal elements can slide along the slots, therein constrained transversally to the sliding direction.
  • the device includes means for blocking the sliding of the longitudinal elements associable to the coupling elements.
  • the interconnecting device presents the drawback of not affording a perfect joint since there will inevitably be residual sliding play between the shaped tips of the longitudinal elements and the slots receiving them.
  • the object of the present invention is to overcome the drawbacks described above.
  • the stated object is realized in an assembly of elements as characterized in the appended claims, which comprises at least one multiple coupling element affording a plurality of profiled sockets, and an interlocking longitudinal element of which one end affords a profiled tip accommodated to a matching fit and positively retained by a relative socket, and the remaining end is connected stably to a respective strut.
  • the interlocking geometry of the socket and the tip of the longitudinal element is polyhedric and associable to the concavities of the multiple coupling joints and is such as to stay fixed in combination with the coupling elements of the longitudinal elements and the struts associated to them in the joint.
  • the assembly according to the invention enables a stable connection of the struts to a structural joint of modular embodiment in which the component parts are positively coupled and yet removable one from another.
  • the tip profile exhibits faces convergent in a longitudinal plane containing both the axis of symmetry of the tip itself and the mutually parallel axes of the longitudinal element and the connected strut.
  • the axis of the tip is angled away from the axis of the longitudinal element to a degree whereby the convergent faces are disposed in planes respectively parallel with and angled in relation to the axis of the strut, in such a way as allows of altering the angle between the axis of the strut and the plane in which the parallel or angled face of the tip is offered to the surface of a relative socket afforded by the multiple coupling element.
  • a further advantage of the invention is that the modular joint can be pre-assembled conveniently on the ground, according to erection requirements, and the assembly then fitted into the structure.
  • 1 denotes an assembly of modular elements serving to join the struts 2 of a temporary roof structure, comprising two multiple coupling elements 3 matched one to the other by way of relative mating surfaces 4a and 4b and secured thus with fastening means 7, by means of which to interconnect a plurality of struts 2; the assembly 1 further comprises a plurality of longitudinal coupling elements 8, each associated axially with one end of a relative strut 2, which are insertable between and retained positively by the two multiple coupling elements 3.
  • Each multiple coupling element 3 is of symmetrical embodiment in relation to a centre axis (figs 4, 5, 6 and 7), and each mating surface 4a and 4b affords a respective plurality of profiled sockets 5a and 5b merging with corresponding slots 6 of which the transverse dimensions are smaller than those of the sockets 5a and 5b.
  • the sockets 5a-5b are eight in number and distributed uniformly about a given circumference
  • the single longitudinal coupling element 8 exhibits a body 9 of which one end 9a is connected to the relative strut 2 and the remaining end 9b affords a profiled tip 10 shaped to match the sockets 5a-5b of the multiple coupling elements 3. More exactly, the tip 10 is carried by a shank 20 of rectangular section extending from the body 9 and of shape such as to occupy the corresponding sockets 5a-5b of the two multiple coupling elements 3 with the shank 20 longitudinally disposed in the relative slot 6.
  • the width of the profiled tip 10 is greater than that of the single slots 6 of the multiple coupling elements 3, such that with geometrical interference occasioned between the tip and the elements 3 in a direction coinciding with the axis 91 of the body 9 of the longitudinal element 8, an interlocking fit is established whereby the longitudinal element 8 remains positively retained and yet removable from between the multiple coupling elements 3.
  • the shaped tip 10 of the longitudinal element 8 is polyhedral in shape, exhibiting a first pair of opposite angled faces 12 and 13 converging on a point forward of the body 9 and coinciding with the longitudinal axis 10a of the polyhedron, hence of the tip; in a preferred embodiment, the two faces 12 and 13 will be set at identical angles on each side of the tip axis 10a.
  • the tip 10 of the preferred longitudinal coupling element 8 is also angled away from the axis 91 of the body 9, advantageously to a degree matching the convergence between either of the first faces 12 and 13 and the tip axis 10a. Accordingly, as shown in fig 1, one face 12 of the first pair is disposed parallel with the longitudinal axis 91 of the body 9, hence with the axis of the associated strut 2, whereas the angle between the opposite face 13 and the same axis 91 is equal to the sum of the angles compassed by the two convergent faces 12 and 13 and the tip axis 10a.
  • angles of the first pair of faces 12 and 13 in relation to the axis 10a of the tip 10 will be identical, and advantageously 225° or 15°, in such a manner that the struts 2 can be disposed parallel to the bottom face 14 of the sockets 5a, and angled away at 45° or 30°.
  • 15 and 16 denote second pairs of faces afforded by the profiled tip 10, which are angled in relation to a longitudinal plane containing both the tip axis 10a and the axis 91 of symmetry of the body 9, and of shape such as to wedge to an exact fit in a corresponding socket 5a-5b of the multiple coupling elements 3 when the mating surfaces 4a and 4b are brought together and the fastening means 7 located and tightened; in the preferred embodiment of fig 1 such means 7 consist in a screw 17 of which the axis is disposed normal to the mating surfaces 4a and 4b.
  • Figs 8, 9 and 10 show just three examples of joints that might be fashioned for a suspended structure utilizing the assembly 1 of elements according to the invention, in which the longitudinal elements 8 are connected to the multiple coupling elements 3 in a variety of ways so as to alter the angle of the struts 2 in space to suit different erection requirements.
  • the profiled tip 10 might be disposed in alignment with the shank 20 and the body 9 of the longitudinal element 8, rather than angled; such a solution permits clearly of fashioning structural joints in which the struts 2 can be disposed at one angle only in relation to the multiple connector.
  • the two multiple coupling elements 3 of the assembly are dissimilar one from the other, the one affording a sleeve 50 enabling connection to a vertical strut 2 beneath, the other with the slots 6 extended to accommodate the maximum height of the shank 20. Nonetheless, it will be clear that the two elements 3 might be identical in embodiment without prejudice to the spirit of the invention.
