Definitions

  • the floor supporting frame has a rectangular peripheral frame, a number of parallel upper tensioned elements mounted between anchorage members on the peripheral frame, a number of curved lower tensioned elements below the upper tensioned elements also mounted between anchorage members on the peripheral frame.
  • a rigid lattice beam is connected between the upper and lower tensioned elements and it causes the upper tensioned element to curve upwardly between its anchorage members.
  • the present invention relates to a floor supporting framework.
  • the invention particularily relates to buildings used for the intensive rearing of young domestic animals and factories and other buildings that require that the floors be easily cleaned.
  • the present invention is directed towards providing an improved construction of floor supporting framework and particularly one suitable for use with floors of the type described. This and further objects will become apparent on reading this Specification.
  • the upper tensioned elements and the lower tensioned elements are mutually parallel.
  • the peripheral frame is a rectangular frame.
  • the main advantage of the present invention is that a floor supporting framework is provided which does not cover a considerable amount of the floor area and which at the same time is efficient in use.
  • the floor supporting framework of the present invention combines the advantages of the use of tensioned elements to support the floor without their inherent disadvantages when used in one plane only. If tensioned, elements are used in one plane only, i.e. without the lower tensioned elements of this invention, the resultant longitudinal tensile force generated by a load is inversely proportional to the magnitude of the deflection or sag. Accordingly, if the tensioned elements are so pretensioned as to have little deflection or sag under load the resultant longitudinal tensile force puts an undue stress on the surrounding framework of the building.
  • FIG. 1 is a perspective view of a multi-span floor supporting framework according to the invention
  • FIG. 2 is a cross-sectional view in the direction of the arrows II-II of FIG. 1,
  • FIG. 3 is a cross-sectional view in the direction of the arrows III-III of FIG. 1,
  • FIG. 4 is a diagrammatic view, similar to FIG. 2, of a simple floor construction
  • FIG. 5 is a diagrammatic view, similar to FIG. 2 of a floor supporting framework according to the invention showing the floor supporting framework prior to application of a load, and
  • FIG. 6 is a diagrammatic view similar to FIG. 2, showing the floor supporting framework on application of a load.
  • a multispan floor structure comprising a number of floor supporting frameworks namely two end supporting frameworks indicated generally by the reference numeral 1 and intermediate floor supporting frameworks, indicated generally by the reference numeral 2. Only one of the intermediate floor supporting frameworks 2 is illustrated fully.
  • the intermediate floor supporting framework 2 comprises a peripheral frame formed from a pair of intermediate anchorage beams 3 and portion of a pair of parallel longitudinal beams 4.
  • a plurality of substantially parallel upper tensioned elements 5 are mounted between first anchorage members formed by anchorage members 6 on the intermediate anchorage beams 3: the anchorage members 6 are conventional clamps.
  • the individual clamps may, needless to say, be replaced by a continuous bar clamp extending the full length of each intermediate anchorage beam 3.
  • a number of curved substantially parallel lower tensioned elements 7 are mounted between intermediate anchorage beams 3 below the upper tensioned elements 5.
  • the upper tensioned elements 5 and the lower tensioned elements 7 are high tensile steel bars.
  • a rigid load transferring member connects the lower tensioned elements 7 and the upper tensioned elements 5.
  • the rigid load transferring member 8 is a rigid lattice beam (see FIG. 3) and comprises an upper bar 9, a lower bar 10, two vertical end side bars 11, intermediate bars 12 and reinforcing struts 3.
  • Each lower tensioned element 7 projects through a hole in the intermediate anchorage beam 3 and is tensioned by means ofa nut 14 which engages a screw thread 15 cut on its free end; the nut 14 can obviously be used to adjust the tension in the lower tensioned element 7.
  • the nut 14 and its associated hole forms a second anchorage member for the lower tensioned element 7.
  • Each end floor supporting framework 1 is substantially similar to each intermediate floor supporting framework 2 except that the end floor supporting framework 1 is formed by a peripheral intermediate anchorage beam 3 portion of two of the longitudinal beams 4 and an end anchorage beam 16.
  • Each upper tensioned element 5 projects through the end anchorage beam 16 and is tensioned by means of a nut 17 on a thread 18 cut in the free end of the upper tensioned element 5. Needless to say prior to tensioning the upper tensioned elements 5 they are not secured to the inter: mediate anchorage members.
  • the nut 17 and its associated hole in the anchorage beam 16 forms one of the first anchorage members for an upper tensionedelement 5: the other is formed by an anchorage member Any suitable floor covering may then be secured on top of the floor supporting framework. With pigs and other animals, panels of weldmesh expanded metal,
  • FIGS. 5 and 6 show a diagrammatic view in the direction of the arrows IIII of the floor supporting framework.
  • the floor supporting framework is shown prior to the imposition of a load while FIG. 6 illustrates the floor supporting framework under load.
  • FIG. 4- illustrates a simple floor supporting framework, for clarity this simple floor supporting framework has been illustrated using the same reference numerals as that for the floor supporting framework of the present invention. The operation of the floor supporting framework will be more clearly understood from consideration of these FIGS. 4 to 6 inclusive. Referring initially to'FIG.
  • sile force is proportional tothe square of the span .(see formula B),-thus the totaldeflection of the upper tensioned elements 5 is negligible.
  • a floor supporting framework which. comprises in,
  • said rigid load transferring frame disposed within the said peripheral frame between opposing beam members opposite that containing said first and second anchorage members
  • peripheral frame is a rectangular frame having two longitudinal beams and two anchorage beams interconnecting the longitudinal beams, the anchorage beams carrying the anchorage members, and a plurality of 'the rigid load transferring members affixed to the longitudinal beams.
