Definitions

  • the articulators incorporate a valve actuable when the articulators are subjected to a predetermined load to permit a change of length of the articulator and a consequent-variation of the angle between piers and transverse structure and thus to relieve excessive stresses on the bridge structure.
  • This invention aims at avoiding such overstressing and consequent damage by providing an arrangement whereby the angle, measured in a plane transverse to the bridge, between a pier andthe transverse structure to which it is attached, can change when a predetermined critical loading is reached so that differential settlement can be accommodated without substantial lateral movement of the bridge.
  • the invention therefore comprises apparatus for the construction of a bridge incorporating piers pivotally connected to a transverse structure for articulation in aplane transverse to the bridge, the angles between the piers and the transverse structure being normally maintained at predetermined values by hydraulic articulators each connected to a pier and to the transverse structure and extending obliquely across the angle therebetween, each such articulator having a release valve operative, when a predetermined critical load on the articulator is exceeded, to permit change of length of the articulator and variation of the angle between the associated pier and the transverse structure.
  • connections between the transverse structure'and the piers and between the hydraulic articulators and, on the one hand, the piers and on the other hand, the transverse structure may be either direct attachments or indirect attachments through an intermediate member or members.
  • the transverse structure may be an integral part of a bridge span or an attachment thereto or may be a separate member, for example a cross beam upon which a bridge span is or will be supported.
  • the invention is, of course, particularly useful in the construction of temporary bridges where it is not possible to prepare or to select adequately solid footings for the piers.
  • One especially useful application occurs in the construction of abridge in the manner described in our copending Patent Application Serial No. 859,622, filed September 22, 1969, now abandoned, in which the piers are lowered from a bridge sparrwhich has been projected over an obstacle and the pier footings, fol-example on a river bed, may be quite unpredictable.
  • FIGJ is a diagrammatic elevation of a framework on which is supported part of a bridge span and F162 is a similar view of the framework after some settlement has occurred.
  • FlG.3 is a diagrammatic view of an articulator.
  • a bridge span 1 is carried on a cross beam 2 which is slung transversely below the span by anysuitable connecting means 3 which do not form part of this invention and are not, therefore, shown or described in detail.
  • Attached by pivots 4, one to each end of the cross-beam 2 are tubular hip members 5 of rectangular cross-section; and piers 6, each comprising a plurality of leg units 7, joined end to end, extend through the tubular hip members 5 to which they are secured to provide support for the cross-beam 2 and the bridge span 1.
  • the lower ends of the piers are attached to foot members 9 which rest upon the ground 10 below the bridge.
  • the hip members 5 may be provided with internal guides 8, for example pads of polytetrafluoroethylene, to form bearing surfaces for the piers 6.
  • Hydraulic articulators lla,1 lb extend obliquely across the angles between the piers 6 and the crossbeam 2, their upper ends being connected to the tubular hip members 5 and hence, indirectly, to the piers 6 and their lower ends being connected to the crossbeam 2.
  • These articulators are hydraulic rams of a known type, each incorporating a release valve which will sustain a predetermined maximum load on the ram but, when that load is exceeded, will open to allow extension or contraction of the articulator and thus permit a change of angle between the associated pier and the cross-beam.
  • the articulator 11a will contract and the articulator 1112 will extend to allow the bridge to assume a position such as that shown in FIG. 2 without incurring lateral movement of the span 1 and without overstressing the bridge structure.
  • the articulators 11a, 11b could equally well be connected across the angles below the cross beam 2 and could, if desired, be connected directly to the piers 6 instead of to the hip members 5; in fact the hip members are not essential to the invention which could be applied equally well to a bridge in which the piers are directly pivoted upon the cross beam.
  • the bridge span could be constructed in such a way that it is pivoted directly to the piers, a part of its structure constituting a cross-member thus dispensing with the separate cross-beam.
  • FIG. 3 shows, diagrammatically, one suitable articulator of a known type incorporating a cylinder 12, a ram 13 and a hydraulic circuit having a reservoir and pump 14, a value 15 controlling flow direction and two pressure relief valves 16.
  • Another advantage which is obtained when using this arrangement in the method comprising lowering piers from the bridge span is that excessive stresses on the bridge structure due to the water loads on the piers being lowered into a fast flowing river can be prevented. Furthermore the invention reduces the likelihood of structural damage to a bridge due to oscillations built up by traffic using the bridge.
  • Apparatus for the construction of a bridge comprising a transverse structure; piers pivotally connected to said transverse structure for articulation in a plane transverse to the bridge; hydraulic articulators each operatively connected to a pier and to the transverse structure and extending obliquely across the angle therebetween to maintain said angle, normally, at a predetermined value; and a valve in each articulator, operative when a predetermined critical load on the articulator is exceeded, to permit change of length of the articulator and variation of the said angle.
  • transverse structure is a cross-beam on which a bridge span can be supported.
  • Apparatus as claimed in claim 4 incorporating internal guides within the hip members to form bearing surfaces for the piers 6.
  • each hydraulic articulator is a hydraulic ram comprising a cylinder operatively connected to one of a pier and the transverse structure; a ram incorporating a piston slidable longitudinally within the cylinder and operatively connected to the other of a pier and the transverse structure; and a hydraulic circuit connecting chambers on each side of the piston and including a release valve operative when a predetermined pressure is exceeded in one of said chambers to permit an extension or contraction of the articulator and a consequent change in the angle between the associated pier and the transverse structure.
