Definitions

  • This invention relates to an improved means for effecting the application of insulation for fire-proofing covering to a wall section through the use of break-away anchor clip means. More specifically, the invention relates to improved rapid means for effecting the anchoring of a concrete type of covering to a metal wall section by providing a plurality of anchor sections in a long strip, with a thin portion or notch between each anchor section such that each section may be readily broken away from the strip, and in turn greatly increase the speed of welding resulting individual anchor sections to the wall.
  • a heat-resisting concrete, insulating concrete, castable refractory materials, and the like In the placement of a heat-resisting concrete, insulating concrete, castable refractory materials, and the like, to the interior or exterior surfaces of a high temperature vessel or heating chamber, to serve as a heat-protecting covering or insulating lining, it is necessary that suitable anchors be first installed on the wall surfaces whereby the insulating material may be attached.
  • Various types of anchorages have been utilized in connection with heatresisting concretes and insulating materials, as for example, stud bolts or spacers which in turn support a wire fabric, or cotter pins and split pins, the bent legs of which may serve to hold or bond with the protective material.
  • the present invention provides a method for forming an anchored concrete type of covering or lining to a metal wall section which comprises, welding a multiplicity of individual anchor sections to such metal wall in a spaced pattern over the entire surface thereof which is to be covered, with such welded attachment being effected by successively welding end anchor sections from a strip containing a plurality of such anchors, separable at notched points, on to said wall section in said pattern and subsequent to welding each individual end anchor effecting the lifting and breaking away of the remaining strip at the notch next to said welded end section whereby to permit the welding of a next resulting end section of such strip to the metal wall in successive welding operations, and then effecting the placement of a protective covering material over the spaced anchor sections and said wall section to provide said anchored covering therefor.
  • strips of anchor clips or sections provide that each anchor section thereof is of a V-shape or U-form and has a substantially small flat surface at a point that will be utilized for welding attachment to the wall surface. It is not intended, however, to limit the formation of the anchoring strips to any one type or shape of material.
  • V- shaped as referred to hereinafter is used generically, and shall include V-shaped sections, or Z-shaped and L-shaped sections, as well as curved U-shaped forms.
  • the strip is formed of heavy gage, say from .12" to .25", round wire or of small diameter rods, however, small sized rectangular or oval-shaped wire or rods may be utilized for the formation of the anchor sections.
  • a preferred construction deforms the wire stock to provide a multiple anchor strip having all of the anchoring sections formed or arranged in one plane and the thinned or notched portions positioned between anchor sections such that the notches face the V-portions of the strip.
  • the resulting strips may be readily stacked and packaged for shipment and storage.
  • the placing of the notches on the side of the strip facing the plurality of V- or U-shaped sections permits the breaking of an individual section by an installers movement which is in the same plane in which the U-shaped deformed anchor sections lie. The rapid, simple, break-away movement by the installer after each weld provides for the present improved method of covering wall sections.
  • FIGURE 1 is a diagrammatic view of one embodiment of a multiple anchor strip.
  • FIGURE 2 shows, in a perspective type of view, the attachment of anchor sections from a multiple anchor strip and a staggered pattern of anchor arrangement in rows.
  • FIGURE 3 of the drawing shows, in cross-section, one arrangement for the installation of individual anchor sections against the wall surface of a heater or vessel and the placement of a lining material.
  • FIGURE 4 shows a modified serpentine form of multiple section strip having symmetry with respect to the formation of the plurality of anchor sections therein.
  • FIGURE 1 of the drawing there is shown a plurality of V-like sections 1 formed within a strip of deformed wire or rod. Between each of the sections 1 is a portion having a reduced cross-sectional area by reason of a notch or cut 2 which in turn provides means whereby each section may be broken away from the strip. Also shown at the end of the strip is a short straight section 3 which serves as a holding piece for the workman when effecting the attachment of the last of the anchoring sections 1 near the end of the strip. It is not intended to limit the anchoring strip to any one type of notch or cut 2 in fabricating the multiple anchor strips, since the depth of the notch 2 may be varied.
  • the metal remaining uncut above the notch varies in accordance with the diameter of the wire stock being utilized and perhaps in accordance with the brittleness, or ductility, of the stock being fabricated.
  • the notches may be varied to provide a desired predetermined easy breaking effort while precluding breakage of the strips during their shipping and handling. If too deep a notch is utilized, the strips may be broken too easily while being handled in shipment and prior to the workman utilizing them in installation, while on the other hand, if a shallow notch is utilized with a highly ductile metal, then it may be necessary to have undue eifort used in effecting the breaking away of each anchor section from the strip.
  • the strip has all of the sections 1 deformed in a manner such that they are arranged in the same plane, having been deformed from the wire stock in a unidirectional manner.
  • a preferred arrangement has the various notches 2 placed on the undersides of the straight portions between sections 1 with respect to the embodiment illustrated in FIGURE 1 such that each notch faces in the direction of the deformed anchor sections 1. This permits the breaking off of the individual sections 1 by an upward movement within the plane in which the individual sections lie.
  • the upward breaking motion is, of course, made by the workman after he has welded the end anchor section of the strip. Also, preferably, after welding an end anchor section, he then grips the strip adjacent the welded section so that he breaks only that one anchor away from the strip.
  • Each of the sections 1, of the embodiment of FIGURE 1 may be provided with a small substantially fiat portion 4 at the lower extremity of each section 1, such portion being utilized for contact with and attachment to a panel or wall surface.
  • the V-shape design is a desirable form in that it provides a small or short length for contact with the wall surface and holds the amount of weld to a minimum. With wide contact lengths the welder may tend to lay down an excessive amount of weld metal and spend more time than necessary with each anchor section.
  • the sections 1 are placed in a plurality of spaced rows AA and BB, and, in addition, the alternate anchors in each of the respective rows are turned at right angles to one another such that there is in turn obtained a maximum bond between the plurality of anchors and the heat resisting concrete, or other insulating material, which is applied over the anchoring means 1.
  • the anchors are positioned in one direction, there is a tendency for cracks to occur in the concrete covering.
  • all clips turned in one direction in the various adjacent rows are welded in place, then subsequently all of the anchor clips in the or right-angle direction are welded in place in the given area in between the others.
  • the diagrammatic embodiment illustrated in FIGURE 3 indicates that a plastic type of concrete or insulating material 6 has been applied over the anchors 1 and against the wall surface 5.
  • the lining material 6 may comprise an insulating concrete, such as haydite-luminite concrete or calcium-aluminate cement with a temperature resistant aggregate of crushed firebrick, vermiculite, perlite, and the like. Such material may be troweled, sprayed or otherwise placed over the anchors and against the surface of the wall section.
  • the anchors extend away from the wall surface approximately half the depth of the insulating material applied over them, thus, it is obvious that the anchor sections 1 may be formed in any particular batch of multiple anchor strips such that they will have a depth correlating to the thickness of insulating material which is to be ultimately applied over the particular anchors. Stated another way, it is preferred that the outer projecting ends of the anchor clips be buried substantially below the interior surface of the liner material such that they will not be subjected to the high internal temperatures of the inside of the particular chamber.
  • the anchor sections 1 may be made of N0.
  • a strip having such sized V-shaped sections may contain about 10 anchor sections and thus be of the order of 33 to 34 inches long.
  • FIGURE 1 The shape of the anchor strips in FIGURE 1 are illustrated to be of a substantially V-shape, however, again, it is to be pointed out that the present multiple anchor strips should not be limited to any one type of deformation or shape for the individual anchor sections 1. It is, of course, a requisite for the present invention that notched strips of anchors are utilized to speed up attachment and that each anchor section has outwardly projecting portions after installation capable of forming a desirable bond with the insulation material being applied around them.
  • a modified form of anchor section and multiple anchor strip is indicated in FIGURE 4 of the drawing. In this latter embodiment, symmetrically shaped deformations are formed in the wire stock providing a serpentine shaped strip with individual anchor sections 7 which have a U- shaped form.
  • the notches 8, or the resulting reduced cross-sectional area portions between the anchors are provided along one edge, or one side, of the continuous strip, and as a result, a plurality of indivdiual U-shaped anchor sections 7 are formed in the strip.
  • the type and size may vary, and similarly for notches 8 in FIGURE 4, their size or depth may vary in accordance with the gage of the wire stock utilized for forming the anchors, as well as with the ductility of the stock.
  • the present invention is directed to an improved method of rapidly and securely attaching a covering material to a wall section
  • it is not intended to limit the invention to any one way of forming the thinned sections, or notches, for they may be formed by a partial cutting operation or by a suitable die forming or pressuring operation which in turn will effect the thinning of the metal such that each section may be readily broken from the strip.
  • a method of forming an anchored concrete covering on a metal wall section which comprises, attaching a multiplicity of individual anchor sections shaped as a V or U in a spaced pattern to the surface of the metal wall to be covered, effecting such attachment by successively welding to the wall in said pattern the apex of end anchor sections from a strip of attached anchors separable from each other at notched points spaced between each of such sections and, subsequent to welding each individual end anchor, lifting and breaking away the remaining strip from the welded individual end anchor at the notch next to said welded end anchor whereby to permit the welding of a next resulting end section of said strip to the metal wall section in successive welding operations, and subsequently applying a protective covering material over the spaced anchor sections and said wall section to provide said anchored covering therefor.
  • the method of claim 1 further characterized by positioning said spaced pattern of anchor sections in a plurality of spaced two-way rows in which adjacent anchor sections in such rows are at right angles to one another.
