Definitions

  • ABSTRACT The present invention concerns the assemblage of the elements of a dismountable metal frame, and more particularly a mast, such as a crane tower which has to be raised by successive superimposed elements or, on the contrary, dismounted.
  • the assemblage devices must be designed in such a manner as to permit the transmission of the components of the stresses in several directions, that is to say in a mast the longitudinal stresses exerted on the uprights placed in prolongation of one another, and the transverse stresses, transmitted more particularly by the cross-braces and resulting from shearing stresses and torques.
  • the assemblage device comprises the combination of parts generally provided with connecting bolts, which receive the longitudinal stresses, and other parts, distinct from the preceding parts, intended for transmitting the transverse stresses, and preferably also for connecting the cross-braces to the uprights, these means projecting with respect to the surface of the joint on each of the pieces to be assembled, externally but tangentially to the perimeter of the said surface.
  • the present invention concerns the assemblage of the elements of a dismountable metal frame, and more particularly a mast, such as a crane tower which has to be raised by successive superimposed elements or, on the contrary, dismounted.
  • the assemblage devices must be designed in such a manner as to permit the transmission of the compo nents of the stresses in several directions, that is to say in a mast the longitudinal stresses exerted on the principal members or the uprights placed in prolongation of one another, and the transverse stresses, transmitted more particularly by the cross-braces and resulting from shearing stresses and torques.
  • the assemblage device comprises the combination of parts generally provided with connecting bolts, which receive the longitudinal stresses, and other parts, distinct from the preceding parts, intended for transmitting the transverse stresses, and preferably also for connecting the cross-braces to the uprights, these means projecting with respect to the surface of the joint on each of the pieces to be assembled, externally but tangentially to the perimeter of the said surface.
  • the invention covers metal frameworks, in particular masts or towers comprising elements assembled by the device concerned.
  • FIG. I is a diagrammatic perspective view showing the upper end of a mast element and the lower end of one of the members of the element above.
  • FIG. 2 shows in perspective on a larger scale the upper end of a member of an element and the lower end of the corresponding member of the element above.
  • FIG. 3 is a view in horizontal projection of the upper end of a member of an element.
  • FIG. 4 is a view in elevation corresponding to FIG. 3
  • FIGS. 10 and 11 show, in elevation and plan, an assemblage device for the panels of a mast element in application of the invention.
  • FIGS. 12 and 13 show on a larger scale, in elevation and in horizontal projection, the detail of the assemblage device before connection of its two portions.
  • FIGS. 14, I5 and 16 correspond respectively to FIGS. 10, I1 and I2 and concern a modification.
  • FIG. I shows in perspective the upper end of the four vertical uprights or members of a metal mast element of square section, and the lower end of one only of the four uprights of the element above, which is to be superimposed and assembled with the first element, while FIG. 2 shows on a slightly larger scale the uprights on the left of FIG. 1.
  • FIGS. 3, 4 and 5 recapitulating the means shown in FIG. 2, show them this time in vertical and horizontal projection.
  • Each of the box uprights of square section such as l, 2, 3, 4 (or 1, 2', 3, 4, the upright 1 only being shown), is provided at each of its ends with a bridle 5 (or 5, see above) provided with two bores 6, 7 for the passage of assemblage bolts, the said bridles being set back with respect to the joint plane.
  • These bridles with their bolts which may or may not be prestressed, serve for transmitting their longitudinal stresses to the uprights, that is to say, the stresses parallel to the arrow A of FIG. 2; as will be seen in FIGS. 3 and 5, the bridles are placed obliquely with respect to the sides of the section of the upright and pass through this section.
  • This arrangement may be modified by providing two long ribs 8, 9 parallel to the axis of the upright and welded respectively to the two faces of the upright which are turned towards the interior of the section of the element formed by the four uprights. On each of the uprights, these ribs project with respect to the joint plane (plane I J in FIG. 4) and are provided with a slight chamfer to facilitate fitting (see FIG. 4).
  • the space 11 between the ribs 8, 9 of the upper end of an upright and the edge a of the upright which is inside the section of the element is less by the thickness of at least one rib than the corresponding space h between the ribs 8' and 9' of the lower end of an upright and the corresponding edge a.
  • the upper end of the uprights is welded to a plate 10 at right-angles to the edges of the uprights and closing the section of the latter.
  • the lower end of the uprights remaining free is supported during assemblage on the plate 10 of the uprights below (FIG. 4).
  • the said plate 10 may project on the faces of the upright, externally of the section of the element as shown in FIGS. 2, 3 and 4, but it is flush with the two faces of the uprights which are inside the section of the element permitting fitting by the ribs and bringing into alignment the edges a and a.
  • the ribs are situated tangentially t the perimeter of the said plate.
  • the joint plane of two successive uprights is the plane marked J] in FIG. 4 or again the plane of FIG. 3.
  • the square cccc shown in dashed lines is the section of the element situated below the plane of the drawing whose respective uprights occupy the squares a h c d, while the squareffff, drawn in chain lines, represents the section of the element situated above the plane of the drawing, whose uprights bear on the plates 10 and have the sections represented by the four squares u e fg.
  • the bridles 5 and 5 are placed in a manner such that the axes of the bores 6, 7 and 6, 7' are in coincidence from one upright to the next, which involves a variation in the position of the bridles with respect to the section of the uprights when the said section itself varies. This will be seen by camparison of FIGS. 3 and 5.
  • the ribs 8, 9, 8', 9' are used for fixing the crossbraces 11 and the ties l2 connecting the uprights together. This fixing may be carried out in any appropriate manner.
  • the drawing shows fixing by plates 13 welded to the ends of the cross-braces or the ties and to the ribs, the latter being shaped to offer edges of suitable inclination such as l4, 14.
  • FIG. 7, 8 and 9 show a modified embodiment of the assemblage, differing from the previously described embodiment in that the bores 6, 7 and 6, 7 for the passage of the assemblage bolts are no longer provided on a bridle crossing the section of the elements, but rather are provided on solid parts l5, 16, 15, 16 fixed to the external faces of the elements, preferably by welding between the ribs 8, 9 and gussets 17, 18, welded to the external faces of the uprights.
  • This arrangement is particularly applicable when the longitudinal stresses to be transmitted become considerable.
  • FIGS. 10 to 12 show a method of applying the invention to the assemblage of panels which are to form a tower.
  • FIG. 11 in which the four panels are represented in horizontal projection, positioned opposite one another for assemblage, shows that each panel comprises an upright I and two pairs ofhalfcross-braces Ila, 11a; 11h, 11h, these pairs being situated in two perpendicular planes passing through the axis of the upright.
  • the half cross-braces are fixed as described in the foregoing to terminal ribs of the uprights and are assembled together to form a triangle, it being possible to provide ties, such as 12, at the apex of the said triangle.
  • each triangle of cross-braces comprises a plate or sole 20 and 20', respectively, which soles are applied against one another during assemblage.
  • These soles are provided with holes 21, 21. in which bolts may be introduced for thus supporting the components of stresses exerted perpendicularly to the said soles.
  • the said soles include at their ends projections 22, 22' adapted to overlap during assemblage, such that the projections 22 of one sole 20 hearing on the edge of the other sole 20 and vice versa so that the projection 22' bears on the edge of the plate 20.
  • This interlocking enables the components of the stresses exerted parallel to the soles to be absorbed and thus enables the shearing stresses on the bolts to be sup pressed.
  • FIGS. 14 to 16 differs from the preceding embodiment in that on each panel the crossbraces 11a extend over almost the entire width of the panel and only in one plane, such that assemblage is effected against one upright.
  • the alignment of the edges (1 a of the uprights, which are in the interior of the superimposed elements, has the advantage of permitting sliding in the tower, from its base to its summit, an important element for raising the tower, as is the case in some types of telescopic cranes.
  • the invention is not, however, limited to this type of alignment of the internal edges.
  • a generally vertical mast structure designed for end-to-end assembly of upright structural units on top of each other in mutual abutting relationship of the adjacent ends of two successive upright units, namely, the upper end of a first upright unit and the lower end of a second upright unit positioned immediately above said first upright unit and extending upwardly, said first and second upright units being fastened endwise to each other by associated bolting means which extend in a longitudinal direction with respect to said mast structure, wherein the improvement comprises the combination of: an end plate fastened with an upright unit end and flanging the same, said end plate having:
  • mast structure as in claim 1 wherein said end plate comprises at least two adjacent rectilinear peripheral sides which are at an angle to each other and connected at an angular corner point, and said end ribs comprise protruding borders which project beyond said end plate at both said adjacent rectilinear sides thereof.
  • said upright structural units comprise coextensive upright elemental struts each having at least two adjacent planar outer faces which are at an angle to each other equal to that of said rectilinear sides and which are connected at respective straight edges, said rectilinear peripheral sides of said end plate and said planar outer faces of said elemental struts being flush with each other and coextensive, and said corner point of said end plate and said straight edges of said elemental struts being likewise colinear thereby forming together a smooth continuous dihedral rail which extends from top to bottom.
  • each upright structural unit comprises a plurality of like upright elemental struts forming corner elements for said unit and provided with end plate and rib systems, and wherein said corner point of the respective end plates and said straight edges of respective elemental struts are directed towards the inside of said upright structural unit whereby said unit comprises inwardly thereof as many Lil smooth continuous dihedral rails as it has upright elemental struts.
  • each upright structural unit further comprises bracing ties interconnecting said upright elemental struts, said bracing ties bearing against buttress sections of said end ribs spaced from said exposed protruding borders thereof.
  • mast structure as in claim 2 wherein said first upright unit comprises at said upper end thereof a pair of end ribs having exposed protruding borders which project upwardly beyond said end plate at said adjacent rectilinear peripheral sides thereof respectively, and said second upright unit comprises likewise at said lower end thereof a further pair of end ribs having exposed protruding borders which project downwardly beyond said end plate at said same rectilinear peripheral sides thereof, respectively, each rib of one pair of said ribs being adjacent to a rib of the other pair of said ribs and associated with the same rectilinear peripheral side of said end plate.
  • each of said pairs of end ribs forms a dihedral of substantially the same angle as the angle between said two adjacent rectilinear peripheral sides of said end plate.
