Definitions

  • ABSTRACT A compactor for converting a dry, friable cement mix into a concrete panel.
  • the dry, friable mix is inserted into one end of the compactor and the panels produced are removed from the opposite end thereof.
  • a plurality of rotatable members are tandemly spaced along the axis of the compactor and are used to compact the mix as the mix travels along the axis of the apparatus.
  • the compacting means are formed of a series of wheels on each rotatable member which are offset from the compacting means of the adjacent rotatable member in a plane parallel to the axis of the compactor.
  • the rotatable members can be formed of a plural series of wheels or rollers having edges which taper to a center edge.
  • the rotatable members can be formed of a plurality of sheeps foot tampers.
  • the rotatable members can also be formed of an intermix of different types of rollers.
  • the field of art to which the invention pertains includes the field of cement mix compactors, particularly with respect to a compactor which can produce cement panels from a dry, friable mix.
  • the present invention utilizes a dry, friable cement mix which is compacted to form the desired panel.
  • the apparatus enables wall panels of variable thicknesses to be produced. Only low heat to set adhesives for cover sheets is required and the panel which is formed, is movable upon completion of the compaction of the dry mix, so that it can be stored in a desired place and utilized shortly thereafter.
  • FIG. I is a perspective view, partly broken away, of a compactor in accordance with the present invention.
  • FIG. 2 is a schematic, side view of the compactor of FIG. I;
  • FIG. 3 is a top view of the compactor of FIG. 1, partly broken away, illustrating the roller components of the compactor;
  • FIG. 4 is a top view of an alternative arrangement of the roller components which can be utilized in the compactor of FIG. 1;
  • FIG. 5 is a sectional side view of the roller components of FIG. 4, taken along the line 5-5 thereof;
  • FIG. 6 is a view of an alternative arrangement of roller configuration which can be used in the compactor of FIG. 1.
  • FIG. I there is shown an exemplary embodiment of a compactor for producing cement panels constructed in accordance with the principles of the invention.
  • the compactor produces the cement panels from a dry, friable cement mix which is fed into an input feed tray 14 from a mixer.
  • the dry friable mix which can be used in the compactor of FIG. 1 is preferably uncalcined gypsum, i.e. the dihydrite.
  • any of the known or commonly used construction materials can be used, provided that the mix has sufficient fines so that the particles will adhere to each other when relatively dry, i.e. containing 15 to 30 percent water by weight. Examples include clay, cement, adobe soil, and the like. Ten weight percent fines, or more, of about mesh or smaller is satisfactory.
  • a lightweight aggregate can be added for its strength, insulative and/or fire-resistive properties.
  • Such materials include vermiculite, perlite, pumice, diatamaceous earth, shale, or the like.
  • the lightweight aggregate can be added up 10 to 15 percent of the total mix, although amounts of from 5 to 25 percent can be added.
  • a small amount of water for the aggregate e.g. 15 to 30 percent of its weight may be added, if needed for adhesion.
  • An adhesive can also be added, if desired, such as starches, water soluble resin, or the like. Examples include A. E. Staley corn starch, American Cyanamid urea, Philadelphia quartz, sodium silicate, or the like. Such adhesives can be added in amounts of 2 to 10 percent of the total amount of the mix.
  • the dry, friable cement mix from the tray 14 is fed into one end of the trough 16.
  • the trough 16 contains a pair of side walls 18 and 22 which are interconnected by a base bottom wall 24.
  • a conventional drive conveyor belt 26 is driven so that it moves along the top surface of the base bottom wall 24 from the input end of the trough 16, where the dry, friable mix from the tray 14 is fed.
  • a bottom cover sheet 28 is fed from a roll 32 and moves along the axis of the trough 16 adjacent the top surface of the conveyor belt 26. The mix is moved on top of the bottom cover sheet 28 and a screed arm 34, adjacent the tray 14, provides an initial desired level of mix.
  • a plurality of compactor rollers formed, in the drawing, of first, second, and third sets of rollers 42, 44, and 46.
  • first, second, and third sets of rollers 42, 44, and 46 are shown in FIG. 1, but a greater number can be provided. More or less sets of compactor rollers can be utilized, depending upon the desired amount of compaction of the mix which is necessary, and normally is determined by the material being utilized.
  • Each set of rollers 42, 44 and 46 are formed in a plane perpendicular to the longitudinal axis of the trough l6 and are inserted by means of pins 48 into the side walls 18 and 22 of the trough, enabling the compactor rollers to be freely rotatable in the direction shown by the arrows.
  • each of the compactor roller sets 42, 44 and 46 contain a plurality of wheels 52, with the wheels of adjacent rollers being offset from each other in a plane parallel to the axis of the trough 16.
  • the cement mix 62 is fed from a mixer 64 into the trough 16, where it travels progressively down the trough along the axis thereof between the roller sets 42, 44, 46, etc. and the bottom cover sheet 28 positioned adjacent the conveyor belt 26.
  • the roller sets 42, 44 and 46 may be spring biased, shown 3 schematically by means of springs 66,68 .and 72, re spectively, so as to adjust the pressure applied by the rollers to the mix. As the mix moves down the conveyor belt, the mix is compacted to nearly the desired thickness by the rollers. It should be noted that eachfsuccessive roller set 42, 44 and 46 is positioned with its outer cement.
  • the product passes a first pair of smoothing rollers 74 and 76, and a second pair of smoothing rollers 78 and 82 positioned along the longitudinal axis of the conveyor.
  • the first smoothing rollers 74 and 78 abut the top surface of the mix, whereas the second smoothing rollers 76 and 82 are positioned beneath the bottom surface of the cover sheet 28 and adjacent thereto.
  • the smoothing rollers 74, 76, 78 and 82 are adjustable by means (not shown) so that the final thickness of the panel can be formed.
  • the smoothing rollers 74, 76, 78 and 82 are used to assure that a smooth surface is formed on the upper and lower sides of the panel.
  • the mix now in the shape of a panel 84, then travels past a pair of finishing rollers 86 and 88.
  • One finishing roller 86 is positioned adjacent the bottom surface of the cover sheet 28 and a top surface cover sheet 92 from a roller 94 is wound around the other finishing roller 88 and positioned adjacent the top surface of the panel 84.
  • the final shaped panel 84 is then moved by means of a conveyor system 96 to a final storage area where the wall panel can be stored until used.
  • FIG. 4 illustrates an alternative arrangement for compacting the mix.
  • a plurality of rollers 102 and 104 each contain a plurality of sheeps feet tampers 106 positioned thereon, so that alternated series of sheeps feet are staggered and offset along the longitudinal axis of each compactorf'lhe sheeps foot tamper arrangement enables side compaction to occur as the mix iscompacted by the bottom surface 108 of the sheeps foot as well as between adjacent sheeps feet.
  • FIG. 6 illustrates another arrangement wherein the compactor rollers contain discs 112, each of which taper to an outer edge 114, thus forming angular side surfaces 116 between the outer edge, and thecentral portion of the disc 112.
  • an angular force from the side surfaces 116 can be directed to the cement mix to provide desired compaction
  • rollers can be made, dependant on the cement mix being utilized. It should be further understood that the rollers could be a combination of the rollers illustrated in FIGS. 1, 3, 4'and 6. Experimentation can determine the optimum combination of rollers for desired compaction of any particular mix. For example, good compaction was found to occur when three roller sets of sheeps feet of the type illustrated in FIG. 4, followed by five roller sets of offsetwheels of the type illustrated in FIG. 3 was utilized with dihydrite .foot tampers,
  • rollers can be made interchangable so that as the material of the cement mix is changed, the types of rollers utilized can also be varied. Moreover, adjustment of the rollers can be made, so that their separation will provide the desired thickness of a panel.
  • panel wire or steel mesh can be fed into the compactor between the bottom cover sheet 28 and the cement mix, so as to provide a reinforcing member.
  • the compactor as shown has been utilized to provide panels of variable thickness from three-eighths inch to 2 /2 inches. However, panels of lesser or greater thickness could also be formed by the compactor.
  • Apparatus for converting dry cement mix into concrete panels comprising:
  • means for compacting said dry cement mix comprising:
  • said rotatable members having relative laterally offset surfaces with respect to the surfaces of an adjacent rotatable member in a plane parallel to said axis for directly contacting said mix so as to compact said mix between said rotatable members and said flexible sheet as said mix travels along the axis of said apparatus.
