Definitions

  • the present invention relates to a spatial lattice structure consisting of at least one flat ply or a single or double curvature veil, the ply or veil being formed of a network of members assembled in knots by bolts.
  • the connecting stud comprises a cornice welded to one end of a first flat iron, the other end of which is welded orthogonally to a second flat iron.
  • a post is not rigid and behaves dynamically like a ball joint.
  • a network of members (sheet or web) using such a junction element lacks flexural and torsional continuity and hence rigidity.
  • junction elements according to this document are used to produce a curved veil, that is to say by connecting tubes inclined obliquely to the second flat bars, the axes of the tubes assembled in a converging junction node towards a point offset externally. relative to the geometrical position of the knot on the curve of the veil. This offset is the cause of the instability of a veil thus produced and consequently imposes the need to brace this veil with a second veil.
  • the invention relates to a new spatial structure in which the nodes are designed and produced so as to remedy the drawbacks of known embodiments using assembly studs welded to the ends of the members of the spatial structure.
  • each joining stud consists of a hollow prismatic rigid part having a cross section in the form of an isosceles triangle and having its longitudinal axis oriented transversely to the axial direction of the member carrying it, a lateral face of the tenon being fixed at one end of the member transversely to the axial direction of said member, the angle formed by the axial direction of the member on said side face being suitable for the type of spatial structure , and each of the other lateral faces of the tenon being fixed to one face of a similar tenon of another member.
  • the hollow rigid tenon consists of a flat iron having its vertical edges welded to the terminal edges of the wings of an angle iron.
  • the hollow rigid tenon consists of three flat bars welded two by two along their edges parallel to the longitudinal axis of the tenon.
  • the firm fixing of the studs relative to the members on the one hand, and the direct superposition and bolting of the studs on the other hand ensure a very high degree of embedding of these members to the knots.
  • Such embedding not only reduces the buckling length of the members by increasing their stiffness and the buckling stability of the web or web, but also reduces the bending moments of these members by increasing the flexural strength of the web or of the web. sail.
  • the direct assembly of these studs eliminates any independent intermediate piece of the members.
  • the web or the veil is produced only using completely prefabricated and advantageously standardized members and by means of bolts. Such an achievement is particularly economical.
  • the edges at the top of the dihedrons constituting the two tenons of the member are convergent at the center of the spherical surface while being coplanar with the axis of the member.
  • the hollow rigid post can be reinforced at mid-height by a triangular stiffener welded to its wings and to the wall of this post.
  • the spatial structure according to the invention comprises at least two flat sheets or two curved webs braced by tubular diagonals
  • the ends of each diagonal are flattened and each have at least one assembly hole.
  • each end is inserted between two superimposed walls of two hollow rigid studs of the corresponding node and is fixed to these walls by one or more assembly bolts.
  • the spatial structure according to the invention may generally comprise one or more superimposed flat sheets 1, one or more veils 2 superimposed in the form of a cylinder or hyperbolic paraboloid or one or more veils 3 superimposed in the form of a sphere.
  • the spatial structure is a lattice construction formed by successive elements assembled together in nodes 4.
  • the constituent elements of the spatial structure are each time members formed by a bar constituted for example by 'a round tube, this bar can be another profile.
  • the constituent elements in question may be frames or pyramids formed from several members.
  • each node 4 ensures for example the assembly of the ends of four convergent members 5,
  • the members 5 are parallel in pairs and form rectangles or regular squares.
  • Each end of any member 5 carries a tenon comprising a flat wall 6 and an angle 7.
  • the wall 6 could be curved.
  • the flat wall 6 has substantially a square or rectangular configuration.
  • the plate 6 is welded to the end of the frame 5 and is arranged to have two vertical edges and two horizontal edges.
  • the angle 7 which has two identical wings or the same width forming between them for example a right angle, is welded by the edges of its wings along the vertical edges of the plate 6 to form a hollow prismatic assembly part having a section triangular cross. Between its wings, the angle 7 is slightly chamfered. The angle 7 has its vertically directed edge at the top.
  • the vertical plane passing through the longitudinal axis of the member 5 contains the edges at the top of the angles 7, these edges being moreover parallel to each other in this vertical plane.
  • the vertical planes relative to the members 5 all pass through the common straight line for aligning the edges at the top of the angles 7, this common straight line being perpendicular to the flat surface of the ply 1.
  • the wings of the four angles 7 are superimposed and bolted two by two by bolts 8 passing through assembly holes provided in these wings and aligned coaxially.
  • each node 4 assures for example the assembly of the ends of four members 5 and two diagonals 9, all converging.
  • the diagonals 9 are aligned respectively along equidistant lines parallel to the generatrix of the cylindrical surface, while the members 5 are parallel in pairs, each time only between two straight series of diagonals 9.
  • the veil 2 is thus constituted by isosceles triangles well shown in FIG. 4 and each having a diagonal 9 as a base and two neighboring members 5 as equal sides.
  • any member 5 At each end of any member 5 is still welded a stud comprising a flat 6 to which are welded the wings of an angle iron 7 whose non-chamfered edge is parallel to the flat 6. It is a similar welded stud to that of FIG. 1.
  • the edges at the top of the dihedrons constituting the two assembly tenons are left between them.
  • each end 10 of any diagonal 9 is simply flattened as shown in Figure 3.
  • the flattened ends 10 of the two diagonals 9 are 'bolted by bolts 11 on a common dish 12.
  • This dish 12 extends through the node 4 between the angles 7 and is inserted between the latter.
  • the plate 12 and the wings of the angles 7 of the members 5 between which the diagonals 9 are located are bolted together by bolts 8 introduced into corresponding coaxial holes in the wings and the plate 12.
  • each node 4 ensures the assembly of the ends of four converging members 5 for example.
  • any two neighboring members 5 are aligned differently.
  • Veil 3 is made of parallel deformed grams extending in two non-parallel planes.
  • Each end of any member 5 is also made as in the two previous cases with a tenon formed by a flat 6 and an angle iron 7.
  • the edges at the top of the dihedra constituting the two assembly studs of the member converge at the center of the spherical surface while being coplanar with the axis of the member.
  • the spatial structure comprises two superimposed flat sheets or two superimposed curved sheets
  • the sheets or sheets are linked together by diagonals whose ends are flattened and perforated.
  • 8 illustrates a structure including two planar plies joined by one of the diagonals 13.
  • the lower end of a flattened diago - nal 13 is inserted between two adjacent flanges of two brackets 7 of a node 4 of the web lower 1 and is bolted with these wings.
  • the flattened upper end of the diagonal 13 is inserted between the two contiguous wings of two angles 7 of a node 4 of the upper ply and is bolted with these wings.
  • FIG. 7 clearly illustrates the assembly of the ends of the members 5 and diagonals 13 to any node 4 of the lower ply. It is the same for the upper layer. The bond of two. sails curved by diagonals is done in a similar way.
  • each plate 6 may be common, by being welded to it, at two ends of two members 5 or possibly of a member and a diagonal, instead of being at the end of a single member 5.
  • the angle of the wings of each angle 7 is 120 ° instead of 90 °.
  • each node 4 has angles 7 whose number is equal to that of the plates 6 and whose wings define between them angles equal to 360 ° divided by this number.
  • the assembly by superposition of the wings of the angles 7 and by bolting of these wings is similar to the previous cases.
  • each end of each frame 5 is equipped with a tenon formed by a flat 6 and an angle 7, this welded tenon forming a hollow and rigid prism, of triangular and isosceles cross section.
  • a tenon formed by a flat 6 and an angle 7, this welded tenon forming a hollow and rigid prism, of triangular and isosceles cross section.
  • the rigid prism could be obtained by welding three plates welded along their edges parallel to the longitudinal axis of the post. It should be noted that to increase the resistance of the prism, the angle is reinforced at mid-height by a triangular stiffener welded to its wings and flat.
