Definitions

  • the present invention relates to a system for connecting together beams which are part of a structure mounted on a main structure or frame.
  • This system comprises tie rods which are placed in the extension of one another, the core of a beam being fixed between two tie rods placed in the extension of one another.
  • the tie rods are known to take up tensile or compressive forces (thrust) and to ensure sufficient resistance to torsion, whereby the lateral displacements and the torsion of the beams, for example of roofs, mezzanines and pallet supports , can be avoided.
  • US-A-5,077,953 describes a spacer which does not prevent the torsion of the beams.
  • the retractor requires significant perforation of the beams, this perforation weakening the beams.
  • the main lines do not extend in line with each other. Parasitic forces are thus created, which reduce the solidity of the materials used.
  • Another system consists of welding an end plate to a tie rod. Two end plates of two tie rods are connected with a beam between them, using bolts. The cost of such a system is expensive compared to the solution proposed by the invention. The surface of the nozzle pre-galvanized is damaged and therefore loses its resistance to corrosion.
  • a big drawback of this system is its complicated assembly due to the fact that two bolts have to be engaged in the end plates and in the beam located at a high height.
  • British patent GB-B-2169678 makes it possible to avoid, but insufficiently, the torsion of the beam which is fixed between two tie rods, since the two half-supports of the bolts open by shearing by the bending moment in the tie rod.
  • the system according to the invention is a system which has sufficient resistance to bending, which can withstand high tensile and pressure forces, whereby the core of a beam is firmly fixed (loosening being difficult), and which can easily be mounted.
  • system for connecting together beams of a structure between points of attachment of these beams on a main structure comprises axial tie rods located in the extension of one another.
  • the core of a beam is fixed between two tie rods located in the extension of one another, a first tie rod being provided with a threaded rod onto which a nut of a second tie rod is screwed, said threaded rod being engaged in a hole in the soul.
  • the first tie is provided with a support so that the core of the beam is blocked between said support and the nut.
  • This support or nut comprises a flange which is provided with at least one protuberance or ring whose outer edge adjacent to the core defines a surface located (or most of which is located) in the volume obtained by axially extending the outer wall of the tie rod in the vicinity of said support or located in the volume V defined between the extreme edges of two tie rods between which the beam is fixed.
  • the nut and the support comprise a flange provided with at least one protuberance or ring whose adjacent outer edge of the core defines a surface located in the volume obtained by axially extending the outer wall of the tie rod in the vicinity of said nut or located in the volume defined between the extreme edges of the two tie rods between which the beam is fixed.
  • said system comprises axial tie rods extending between two beams or a beam and the main structure, the core d 'a beam being attached to the end of one or more tie rods.
  • Said end of the tie rod is provided with a threaded rod or a nut, on which a support nut is screwed or in which a threaded rod with a support or bolt is screwed, the threaded rod extending through an opening or hole that has the core of the beam, this core then being fixed between the support or bolt and the nut.
  • This support comprises a flange which is provided with at least one protuberance or ring whose adjacent outer edge of the core defines a surface located in the volume obtained by axially extending the outer wall of the tie rod considered in the vicinity of the beam, while the nut comprises a flange which is advantageously provided with at least one protuberance or ring whose adjacent outer edge of the core defines a surface located in the volume obtained by extending axially the outer wall of the tie rod considered in the vicinity of the beam.
  • the support is a flange having two circular protuberances or rings, said protuberances or rings being separated from each other so as to define a groove therebetween.
  • the nut flange also has two circular protrusions or rings separated from each other so as to define a groove therebetween.
  • the central ring or protuberance i.e. adjacent to the axis of the tie in question
  • the central ring or protuberance may have an outer edge (ie distant from the axis) adjacent to the core of the beam defining a surface whose outer edge is not located in the defined volume by axially extending the outer wall of the tie rod in the vicinity of the beam.
  • the support and the nut are arranged so that part of the support touches a part of the core of the beam which is not in the (axial) extension of the part of the core which a part of the nut touches, while a part of the nut touches a part of the core which is not in the (axial) extension of the part of the core which a part of the support touches.
  • the support and the nut are arranged so that part of the support touches a part of the core which is in the extension of the part of the soul touched by part of the nut.
  • the support comprises a flange provided with two circular protuberances or rings, said circular protuberances or rings being spaced from one another to form a groove between them.
  • the nut comprises a flange having two circular protrusions or rings spaced from each other to form a groove between them.
  • a protuberance or ring of the support or nut is located in the extension of a groove of the nut or support.
  • the flanges of the support and the nut are provided with fins, these fins preferably extending between the rings or protuberances, that is to say in the grooves.
  • FIG. 1 shows in perspective a part of a structure of a construction which includes pillars, crosspieces, etc. 1 to which beams 2 are attached by fixing means such as the means represented in FIG. 4.
  • the means 3 shown in Figure 4 is used to attach a profile 2 in the form of Z, C or sigma on a main post 1.
  • the means 3 comprises a plate 5 folded along an axis 7 and provided with a groove or fold 6.
  • the means 3 is fixed for example by means of nuts or bolts 9 to the main upright 1, while bolts can for example be used to fix the profile in the form of Z, C or sigma on the means 3.
  • the system 10 comprises tie rods 10A, 10B, etc. which are placed in the extension of one another. Between the tie rods 10A and 10B is fixed the core 30 of the profile 2, for example in the form of C (see FIG. 2).
  • One end of the tie rod 10A is provided with a threaded rod 12 on which the nut 13 of one end of the tie rod 10B is screwed.
  • the threaded rod 12 passes through the core 30 of the beam 2 through an opening 14.
  • the core 30 of the beam 2 is fixed, wedged or compressed between a support 15 of the tie rod 10A and the nut 13 of the tie rod 10B.
  • the support 15 comprises in the embodiment shown which is one of the preferred forms, a flange 16 comprising two rings 17,18 between which is defined a groove 19.
  • a flange 16 comprising two rings 17,18 between which is defined a groove 19.
  • fins 20 fins connecting the rings 17,18
  • This flange, fins and rings are for example made of a synthetic material, for example reinforced polyamide (fiberglass).
  • the nut 13 is, in the embodiment shown, also provided with a flange 16 with two rings 17,18 between which a groove 19 is defined and which are connected to each other by fins 20 s' extending into the throat 19.
  • the support 15 and the nut 13 are arranged in such a way that the parts of the core 30 that touch the rings 17, 18 of the support 15 are in the extension (direction of the axis X of the tie rod) of the parts of the core 30 that the rings 17, 18 of the nut 13 touch.
  • the rings 17 of the support 15 and of the nut 13 have an edge 17A adjacent to the core 30 of the beam and directed towards the ring 18 (that is to say distant from the 'axis X), which defines a surface located in the volume V obtained by extending in the axial direction X the outer wall of the tie rods 10A, 10B, that is to say in the case shown in the volume V defined between the edge end (100) of the outer wall of the tie rod 10A (edge facing the core 30) and the end edge (101) of the outer wall of the tie rod 10B (edge facing the core 30).
  • the surface defined by said edge 17a is advantageously distant from a distance of 1 mm, preferably at least 2 mm, in particular from 3 to 5 mm from the external surface of said volume.
  • the fins 20 advantageously have an upper surface which initially does not correspond to the upper surface of the ring 17, nor to the upper surface of the ring 18 (upper surface of the fins slightly set back from the upper surfaces of the rings 17,18, before mounting). After mounting, these upper surfaces advantageously extend in the same plane W. These fins 20 somehow form fingers integral with the central ring 17, said central ring extending in the volume V defined by axially extending the outer wall of the tie rod, while said fins extend out of said volume V.
  • the nut 13 and the support 15 consist of an element which is shown in FIG. 5.
  • This element 21 has a substantially cylindrical shape and has at its two ends a recess 22, 23.
  • the recess 22 is provided with a thread on which the end of a threaded rod can be screwed to fix it.
  • the recess 23 is provided with fins 24 to increase the rigidity of the element.
  • the element has an annular groove 25 which serves to fix the element 21 to one end of a nozzle or pipe 26. By deformation of the nozzle or pipe, the element 21 can no longer slide in the axial or longitudinal direction X from nozzle 26.
  • the end 27 of the element 21 which is engaged in the pipe or nozzle has a tapered edge to facilitate the placement or mounting of the element 21 in said pipe or nozzle 26.
  • the element is advantageously made of synthetic material.
  • the nozzle 26 is provided for example in the direction of its length (X) with one or several interior protuberances 28.
  • the nozzle 26 is provided for example in the direction of its length (X) with one or several interior protuberances 28.
  • the end 29 of the element 21 carries the flange 16, the rings 17,18 and the fins 20.
  • FIG 3 shows another embodiment of a system according to the invention (Detail B of Figure 1).
  • the beam 2 consists for example of a sigma type profile which is provided at the ends of the core 30 with a flange 31.
  • This flange 31 comprises a lip which is folded in such a way that the ends are turned towards plane V of the core 30.
  • Such a profile has many advantages, including, among other things, better rigidity, better resistance for a determined maximum height, the edges of the profile are not visible, elimination of the risk of injury to the user during handling, etc.
  • the support 15 of the tie rod 11A has a flange or flange 16 of larger diameter than the flange or flange 16 of the nut 13.
  • the rings 17 touch parts of the core 30 which are in line with one another (relative to the X axis of the tie rods 11A and 11B).
  • the ring 18 of the nut 13 touches a part of the core 30 which is not in the extension of the part of the core 30 that the ring 18 of the support touches.
  • the ring 18 of the nut 13 is in fact in the extension of the groove 19 of the support 15 (groove 19 which is provided with fins 20).
  • This embodiment seems to be excellent as regards its flexural rigidity, but also as regards the absence of risk of loosening.
  • Figure 10 shows another embodiment of a tie rod which can be used.
  • This tie is similar to the tie shown in Figure 2, except that the groove 19 is not provided with fins.
  • the fins 20 are placed on the face of the flange 16 opposite the face carrying the rings 17 and 18.
  • the first beam and the last beam are fixed by means of a bolt and a ring or washer, which is screwed into the thread of the free ends of the extreme tie rods.
  • Figure 11 shows a system for connecting two beams, tie rods 10 extending between the beam 2A and the beam 2B.
  • the tie rod 10 is provided at its two ends with a nut 13, the groove of which is not provided with fins.
  • the fins 20 are placed on the face of the flange 16 opposite the face carrying the rings 17 and 18.
  • the first beam and the last beam are fixed by means of a bolt and a ring or washer, which is screwed into the thread of the free ends of the extreme tie rods.
  • Figure 11 shows a system for connecting two beams, tie rods 10 extending between the beam 2A and the beam 2B.
  • the tie rod 10 is provided at its two ends with a nut 13 into which a threaded rod can be screwed.
  • the tie rod may possibly be fitted with threaded rods 12.
  • the threaded rod 12 of a bolt is screwed into the nut 13, so that the core 30 of the profile 2B is fixed or wedged between the support 15 with or without flange 16 and the flange 16 of the nut 13 of the pulling.
  • the support and / or the nut are provided with a flange carrying two rings 17,18. These rings are spaced from each other to form between them a groove 19 in which the fins extend.
