Definitions

  • This invention relates to the construction of bridges, towers, steel -Irames for buildings and other metal framed structures.
  • the object of the present invention is to provide ⁇ simple, relatively cheap and eiiicient meansv erection of metal framed structures a prefabricated braced panel forming the basic element of the structure and so constructed that a number of these panels may be joined end to end to form a girder of any desired length.
  • the panels may also be connected insuperposed relationship to give a, girder of any desired depth and, further, they may be united side by side to produce a girder of any desired width ⁇ -
  • the aiiixing of the panels may be eiected by pins, bolts, clamps, or other suitable means not involving the exercise of any special skill on the part of the erector.
  • the invention not only provides girders whose strength (in resistance to bending moment or shear) is variable according to the form in which they are made up but also enables the structure to be readily broken down, when required, into components of a size suitable for ease of handling and transportation, the latter advantage applying also in the case of the erection of the structure.
  • FIG. 1 is a more or less diagrammatic side elevation of a bridge formed in accordance with the invention.
  • Figure 6 is an end elevation of Figure 2, part being broken away.
  • Figures '7 and 8 are respectively a plan and side elevation showing a iitting designed to enable panels to be secured at an angle to one another, and
  • Figure 9 is an end elevation of a section incorporating a hinge to enable an articulated joint to be formedin a girder.
  • Figure 10 is a section on the line Ill-I0 of Figure 9 and Figure 1l is a plan of the upper part of Figure 9.
  • I provide a basic element shown in detail in Figures 2 and 3 in the form of a prefabricated braced panel consisting in an allwelded frame of, say,V ten feet in length by iive feet in depth; in which the chords ab are each formed of two rolled channels spaced from one another back to back, and the web or vertical members are constituted by rolled steel joists c of, say, I or H section interposed between the webs of the chord channels.
  • the panels are provided with male jaws d at one end and female jaws e at the other so that any number of panels may be connected together end to end as shown in Figure 1 by means of simple pin connections in order to form a girder of any desired length. Moreover a plurality of panels may be secured to one another in superposed relationship by means, for example, of tapered or other bolts f ( Figure 2) inserted through sockets g provided between the channels forming the top and bottom chords.
  • the bottom chords of the panels are preferably fitted with -dowels i which serve to position cross-girders 1c supporting the deck l of a bridge or cross-girders forming part of any other structure, the number and disposition of the crossgirders being varied in accordance with 'the magnitude of the load to be carried or other practical requirements.
  • the cross-girdersr are provided with holes in which engage the dowels on the bottom chords of the panels and preferably I provide a series of such holes in each cross-girder so as ⁇ to allow their-use with asinglerow of panelsconstituting the main girder, or with two or more rows of' panels arranged side by side to form single. double. or other multiple main girders.
  • thecrcss-girders aresecured to theverticalsand held upright by means of suitable quick action clamps 1n.
  • a single row of panels When a single row of panels is employed for forming the main girder they may be laterally braced by means of raking struts n ( Figure 6) connecting the upper parts of the panels with projections or brackets on the cross-girders and when two or more rows of panels side by side are employed they may be additionally braced by means of smaller braced panels o of the same general form bolted between adjacent rows of panels either vertically at liunctions or horizontally on the top of the panels or both systems may be used together.
  • the deck l of the bridge which rests upon the cross-girders may be formed of weldedup stringer panels made up of groups of three longitudinal Joists p with spacing and distributing members q between and the wearing surface l and kerbs r are placed' on top of the stringer panels.
  • Figures 7 and 8 show a cruciform fitting u which enables panels v to be connected at right angles (or any other angle) to one another.
  • Figures 9 to 11 show a special section incorporating a hinge, to enable an articulated Joint to be made in a glrder.
  • This consists of two welded or other posts a'a2 each having on one side at top and bottom holes b'bz by which they may be secured, by means of pins, to astandard panel, the post a' being adapted to be secured to the female jaws e of a panel, and the post a2 to the male jaws d.
  • On the other side of the posts at the bottom are the forked members c'ca adapted to interlock and to be united by a pin through the holes e' forming a hinge by which the parts may be articulated.
  • two'adjacent girders may be made to meet on a common bearing and to articulate about that bearing as might be required on a consecutive series of bridge spans in a viaduct, for example.
  • a particular advantage of the invention when g asvaoss applied te bridges; for example. is that it enables agirdertobeassembledinskeletonformofonly suiiicient strength to carry its own weight. in which form it may be most easily launched across a gap. Thereafterl it may be readily strengthened by adding another "storey” and/or another “bank” of panels to the necessary extent to enable it to carry whatever loads may be required n otherwise.
  • a prefabricated braced panel including upper and lower parallel chords each composed of two members spaced from each other, joists connected at their ends between members forming the chords to maintain them in spaced relation and forming the web of the panel, means between said chord members to enable panels to be connected in superpolcd relation to oneanother, male jaw members extending longitudinally from adjacent ends of the chords at one end of the panel. and female jaws extending longitudinally from the chords at the other end of the panel, whereby a plurality of panels may be united end to end4 to form a glrder by disposing the female jaws of one panel to receive the male jaws of an adjacent panel and uniting the two by a simple pin connection capable of taking the necessary stresses,
  • a prefabricated panel according to claim i in which the chords are formed from two rolled channels arranged back to back, sockets being secured between the channels to take bolts for uniting the panels in superposed relation.
