Definitions

  • the object of thev present invention is to provide scafioldings formed of drawn or rolled steel bars, having the same tensile strength and length as the tubular sections usually employed in metal scaiolding.
  • the bars are cross-shaped in section and the thickness of the'material is such as to show a resisting moment to axial pressure combined with flexibility and stresses and weight appreciably equal to that of the tubular sections -usually adopted for scaffolding.
  • the rolled cross shaped elements, in cross-'section, have anl outside surfaceI which is easily reached in any part for protective painting.
  • the coupling can be of the universal pattern, A or, according to an alternative embodiment of lthe invention, it can be made with metal plates, 5
  • the coupling has av device preventing any sliding of parts, not only through friction but in a rigid positive way, obtaining a perfect fit of l5 the bars in the coupling, particularly, where coaxial bars are to be jointed; this means consisting ⁇ of special bolts forming a key seat.
  • Fig. 1 shows in side view a part of the standards with the spacing blocks.
  • 1 25 Fig, 2 is a horizontal section ofthe same.
  • Fig. 3 is a vertical section of same along line 3--3 of Fig. 2.
  • Fig. 4 shows 'a coupling in front view partly broken away.
  • Fig. 5 shows the same in ltop view, partially sectioned.
  • Fig. 6 is a section of Fig. 5 along line 3 6.
  • Fig. 'I is a side view of a first alternative conshown in section.
  • Fig. 8 is a front view of Fig. 7.
  • Fig. 9 is a horizontal section through Fig. '7.
  • Fig. 10 is a section of a plate.
  • Fig. 11 shows a side view of a second alter- 4o native form of coupling, one of the bars being shown in section. l
  • Fig. 12 is a front view of Fig. 11 partly in section.
  • Fig. 13 is a plan view sectioned of Fig. 11. 45 Fig. 14 shows a coupling bolt for the Aform shown in Fig. 11. ,l
  • Fig. 15 shows a side view of a third alternative form, of coupling, one of the bars being -struction of the coupling, one of the bars being 35
  • Fig. 16 is a front view of Fig. l5
  • Fig. i7 is a view similar to Fig. 15 showingv the coupling in section.
  • a is the standard made of an iron-bar wi h a cross-like section
  • b are the fillers or spacing-blocks in the shape of circular segments, with an outer groove c, which are applied to the standards at the crossing points of the vertical and horizontal bars.
  • the wedge or sector shape-of the spacing pieces b leaves a centre space in the shape of a cross into which are placed the iron bars of the scaffold; bolts fg on the coupling serving to tighten the spacing-blocks on the bars.
  • connection between bars canhave any direction, the crossshaped bars being rotatable within the coupling while the connection is securely established on tightening the bolts, by the complete frictional contact between the right sides of the crosssection of the bar and the corresponding faces of the coupling spacing pieces, thus obtaining a surface of contact of much greater extension than with the usual tube couplings.
  • Figs. 7 to 10 are the profile or rolled bars of the scaifoldfl are the plates forming the coupling, which are V shaped in their centre-line, according to the angle between two wings of the cross-shaped bars, while the ends of the plate extend as flanges and are provided with holes for the bolts 8 which tighten the plates I against the profile bars 5 and 6 and connect the two series of plates, thereby clamping the bars together.
  • the central plate I5 of the coupling may have the shape shown, whereby the inside of the plate is so shaped as to fit at I6 the profile of the bar I 5 against which it has to be tightened, so as to adapt itself perfectly against the same, obtaining an extended surface of friction, giving the coupling a firmness and a strength not yet obtained heretofore.
  • the counter-plates I'I and I8 clasp the bar very tight by means of two bolts I9, instead of four, which may be hinged at one end, to ears 20 projecting from the central plate, the opposite ends being inserted in cavities at the extremity of the counter-plates.
  • the scaffolding formed in thisl manner is therefore a very practical one in the field of metal scaifolds and, it can be efficiently employed also in all such metal structures having a semipermanent character as for ⁇ instance: foot bridges, bridges, roofs, tribunes, staircases, barracks, platforms, trestles, scaolds, open work towers, and girders, shelves, etc.
  • coupling plates can be of any other shape, square, polygonal, crossed or round, without departing from the spirit of the invention.
  • a scaffolding comprising'bars substantially cross-shaped in cross section, and couplings for said bars whereby the latter may be connected to each other at any angle, said couplings including parts fitting into at least two of the op# posed angles formed by the cross shape of the bars, and means for drawing and maintaining said parts in engagement with said bars.
  • a scaffolding as claimed in claim l characterized in that said couplings yinclude 4separable members forming an opening for the passage of one of said bars, a wedge-like spacing' said bars, and adjustable connecting'means for i the pairs of members including a key coasting with said bars.
  • a sca'olding as claimed in claim l characterized in that said couplings each include pairs of members, and adjustable connecting means between said pairs of members, the members of each pair being shaped to intert with the angles of the cross shaped bars.
