Definitions

  • the invention relates to a multidirectional connection system for structures comprising a connection piece to which bars defining the structure are fixed according to the preamble of claim 1.
  • French patent 1,520,550 describes a hollow assembly device allowing the circulation of a fluid between concurrent elements.
  • the assembly node comprises a hollow central body on which the fins are fixed, along orthogonal longitudinal planes passing through the axis of the hollow body and through the center of the openings for the passage of the fluid.
  • the fins also extend on the transverse faces of the hollow body.
  • the tubes then have a single direction determined during the construction of the node by the relative positions of the opening of the central body, of the fixing hole in the fin and of the edge of the fin. There is no possibility to modify the angles between two crowns.
  • Another assembly device consists of a body in the form of a circular plate, one face of which carries segments of cylindrical rings.
  • the body can receive two forms of fins: one intended for connections in the plane of the plate comprising a stirrup extended by a tail used for fixing the structural elements; another intended for inclined connections on the plane of the plate comprising a circular sector, capable of cooperating with the faces of the central body, on which a tail is fixed obliquely.
  • Each fin is attached separately to the central body using bolts.
  • the fins determine a single direction of attachment of the structural elements.
  • the angle which the fins of one crown make with respect to the fins of the other crown is defined by construction and cannot be modified.
  • the invention aims to achieve a multidirectional connection system providing great flexibility of use and in the form of standardized elements.
  • the multidirectional connection system for structure according to the invention is characterized in that the central body can be separated into at least two parts, along a transverse plane, each of the parts carrying a ring of ears and in that the cooperating faces of the parts of the central body carry positioning means allowing angular offsets of one crown relative to the other.
  • the planes of the ears pass through the axis of the central body or intersect said axis.
  • the connecting piece 1 forms a node to which the bars 2 and 3 are connected defining the structure.
  • the connecting piece 1 comprises a central body 4 on which are fixed ears 5, 6 forming two superimposed rings 7 and 8.
  • the ears 5 of the crown 7 are angularly offset from the ears 6 of the crown 8.
  • the ears 5 of the crown 7 are of approximately rectangular symmetrical shape
  • the mean axis equidistant from the long sides intersecting the axis of the central body and the long sides of the ears 6 of the crown 8 form angles acute with the axis of the central body
  • the middle axis approximately equidistant from the two long sides intersects the axis of the central body at the same point as the middle axis of the ears 5 of the crown 7, which leads to the axes (lines of force of the bars of the structure) attaching to the ears can all be concurrent at a point on the axis of the nucleus.
  • the number of ears of each crown was arbitrarily chosen equal to 4 and the angular offset between the ears of each crown of 45 °.
  • the number of ears of each crown can be arbitrary, the number of ears of one crown not necessarily being equal to the number of ears of the other, and the angular offsets between the ears of each crown do not necessarily give an equidistant distribution of the ears around the central body.
  • FIGS. 2A and 2B comprises a central body separable into at least two parts 11 and 12.
  • Each of the parts carries at its periphery the ears which are either welded or have come directly from molding.
  • the cooperating faces 13 and 14 of the two parts of the central body carry means for angular positioning of a ring relative to the other.
  • part 15 of the ears of part 12 engages in slots 16 provided in the crown 11.
  • the central body parts carry, along their axis, a center hole and / or a bore 17 in which can be introduced a fixing piece, for example a bolt, allowing to block the two parts in the desired position.
  • Part 11 can have slots (shown in broken lines) similar to slots 16 at its upper part and receive another element 12.
  • the center holes and / or bores 17 materialize the axis of the central body and allow precise piercing of the ears.
  • FIG. 3A and 3C Another example of a two-part central body is shown in Figures 3A and 3C.
  • Part 18 has six ears and part 19 (Figure 3C) three ears.
  • Positioning means consisting for example of a lug 20 in the part 18 and of housings 21, allow different angular offsets depending on the use of the connecting piece.
  • the central body consists of two similar parts 22 and 23 (FIGS. 4A and 4B) on the lateral surface of which grooves 24 are provided parallel to the axis of the central body and which enter the body ( Figure 4C).
  • the grooves receive or position the bases 25 and 26 of the ears which are held there, for example by gluing, the body preferably being made of plastic.
  • the base surfaces 27 and 28 of the body parts carry a lug 29 and a housing 30 in the form of a coaxial half-crown. Seen from above, the lug and the housing ( Figure 4C) are arranged in a crown.
  • the body parts carrying the ears ( Figures 4D and 4E) are assembled, in known manner, to form a connecting piece. As previously described, the faces of the ears bear marks 31 facilitating by positioning a piercing range of the ears to receive the structural bars.

  • the parts When the parts are assembled, they define a groove 34 whose section is approximately T-shaped, the crossbar of the T being parallel to the axis of the central body and close to its axis.
  • the end pieces, such as the piece 39, have on their free face 43 a recess 44 coaxial with an axial bore 45.
  • the bases 35 and 36 of the ears 37 and 38 are presented on the pieces 40 assembled back to back and are held by the parts 39 during assembly of the connecting part.
  • the ears can move along the grooves in a plane passing through the axis of the central body or possibly make an angle with this axis and, when the bars are fixed, put themselves in the position of minimum effort.
  • FIGS. 6A and 6C show an embodiment in which the central body is formed of two symmetrical parts 46 and 47, each of the parts having a peripheral groove 48 of approximately rectangular section, the plane of symmetry of which is perpendicular to the axis of the central body , the bottom of the groove having a rib 49 wider at the surface than at the bottom and in particular of T section, the vertical bar of the T or foot being fixed on the bottom of the groove perpendicular to the axis of the central body, the crossbar of the T being parallel to the axis of the central body and flush with the edges of the groove.
  • the peripheral part of the rib carries at least one passage 50 of dimensions equal to the dimension of the groove bottom capable of letting through the base of the ears having a shape approximately complementary to the groove and its rib.
  • FIG. 6C shows in section an embodiment in which the rib is discontinuous and extends, for example, over two or four sectors of each part of the central body. Each of the sectors is separated from the next by a longitudinal wall 51 which ensures greater rigidity of the assembly during assembly.
  • this part comprises at least one yoke 53 crossed by a bore 54 which is brought into line with the bore of the pierced ear as a function of the data from the calculation of the application of forces.
  • the structure connecting bar 2 can be welded directly to this yoke or be maintained.
  • the fastener 52 carries, in the embodiment shown, a second yoke 55 with an axis perpendicular to that cooperating with the ear.

  • FIG. 1 shows a connection node in which all the fixing parts 52 comprise connection means which are connected together by pipes 58 leading to a connection or distribution box 59, which is optionally connected to the source of fluid coolant for cooling or heating the structure.
  • the multidirectional connection system according to the invention makes it possible to use the structural bars for conveying fluids and in particular to have an effective fire fighting network by cooling the bars and by using minus a screed bore as a sprinkler device.
