Definitions

  • the present invention relates to a spatial lattice structure consisting of at least one flat sheet or a single or double curvature veil.
  • the sheet or veil is formed by elements each consisting of a bar, a frame or a pyramid. These prefabricated elements are assembled together at the ends of their constituent members in nodes by mutual bolting of these ends.
  • each end piece includes a tube end and several plates.
  • the end of the tube is intended to be fitted without appreciable play and bolted in relation to the end of the frame.
  • a square plate is welded at the end of the end of the tube perpendicular to its axis.
  • each polygonal plate On the side opposite the end of the tube, two identical polygonal plates are welded along the upper and lower edges of the square plate parallel to each other and to the above axis.
  • a rectangular intermediate plate is welded to the square plate and the polygonal plates and ensures the bracing of the latter.
  • Each polygonal plate has a point with isosceles edges on the side opposite the end of the tube.
  • the object of the invention is a new spatial structure in which the nodes are designed and produced to remedy the aforementioned drawbacks of the known technique.
  • each end of the frames leading to a knot carries a stud formed by a wall which is welded therein and by an angle iron whose wings of the same width are welded to the wall and each have at least one assembly hole.
  • each knot is formed on the one hand, by the superimposition two by two of the angles of the angles of the corresponding members, with the edges of these angles aligned practically along the same straight line normal to the web or to the veil, and on the other hand, by the bolting of these superimposed wings by means of bolts passing through their coaxial assembly holes.
  • the firm fixing of the angles relative to the members on the one hand, and the direct superposition and bolting of these angles on the other hand ensure a very high degree of embedding of these members to the nodes.
  • 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 the bending moments of these members by increasing the bending resistance of this web or of this sail.
  • the direct assembly of these angles 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 aforementioned tenon comprises the wall which is for example formed by a square or rectangular dish, and an angle iron whose edge is parallel to the dish.
  • a spatial structure comprising a flat sheet
  • the edges of the angles of the two studs of the frame are mutually parallel in the aforementioned particular plane passing through the longitudinal axis of this frame, so that the cutting angles of these edges by this plane are zero.
  • the edges of the angles of the two tenons of the member are convergent at the center of the spherical surface in the aforementioned particular plane.
  • the edges of the angles of the two tenons of the member are left between them and lie outside the above-mentioned particular plane.
  • the angle of the post is reinforced. at mid-height by a triangular stiffener welded to the wings and to the wall of this post.
  • each diagonal is flattened and each have at least one assembly hole.
  • each end is inserted between two superposed wings of two angles of the corresponding node and is bolted to these wings by the assembly bolt (s) of the latter.
  • the spatial structure according to the invention may generally comprise one or more flat layers 1 superimposed, 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 each 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 by 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 regular rectangles or 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 iron 7 has two identical wings or the same width forming between them for example a right angle. Between its wings, the angle 7 is slightly chamfered. In fact, the angle iron 7 is welded by the edges of its wings, along the vertical edges of the plate 6. Thus, the angle iron 7 has its fictitious edge directed vertically. In each member 5 provided with its end tenons, the vertical plane passing through the longitudinal axis of the member 5 contains the fictitious edges of the angles 7 and therefore cuts these at zero angles, these edges being moreover parallel between them in this vertical plane.
  • each node 4 the vertical planes relative to the members 5 all pass through the common straight line of alignment of the fictitious edges of the angles 7 and make zero angles with this common straight line, which is perpendicular to the flat surface of the sheet 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 ensures, 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 generatice of the cylindrical surface, while the members 5 are parallel two by two each time only between two straight series of diagonals 9.
  • the veil 2 is thus consisting of isosceles triangles well shown in Figure 4 and each having as a base, a diagonal 9 and as equal sides, two neighboring members 5.
  • 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 welded stud similar to that of the first figure.
  • each member 5 provided with its two end tenons, there is a plane passing through the longitudinal axis of the member 5 and cutting the edges of the angles 7 at equal angles other than zero.
  • the two edges in question are two left straight segments arranged on either side of the aforementioned particular plane.
  • each node 4 the particular planes relating to the members 5 intersect the common line of alignment of the edges of the angles 7 according to equal non-zero angles, this common line being normal to the surface of the web 2.
  • 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 dish 12 and the wings of the brackets 7 of the flanges 5 between which the diagonals lie 9 are bolted together by bolts 8 inserted in holes corre - sponding coaxial of these wings 12 and of the dish.
  • each node 4 ensures the assembly of the ends of four convergent members 5 for example.
  • any two neighboring members 5 are aligned differently.
  • Veil 3 is made up deformed parallelograms 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 7.
  • the particular planes relating to the members 5 all pass through the common straight line of alignment of the angles of the angles 7, this common straight line being normal to the spherical surface of the web 3.
  • the layers 1 formed and produced as in the first case are connected to each other by diagonals 13 the ends of which are flattened and perforated.
  • the flattened lower end of a diagonal 13 is inserted between two adjacent wings of two angles 7 of a node 4 of the lower ply 1 and is bolted with these wings.
  • the also 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.
  • the sheets 1 being parallel, the diagonals 13 of a node 4 are all similarly inclined with respect to the straight line of alignment of the edges of the angles 7 relative to this node 4.
  • FIG. 7 clearly illustrates the assembly of. ends of the members 5 and of the diagonals 13 at any node 4 of the lower ply. It is the same for the upper layer.
  • connection of two flat layers 1 by diagonals 13 can be done as in the case of two superimposed webs 2 and 3.
  • 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 arranged two by two close to each other.
  • the angle is reinforced at mid-height by a triangular stiffener welded to its wings and flat.
