Definitions

  • the U.S. Patent of Kastenbein, 2,855,653 shows a system for casting tile-faced panels which includes sucking the individual tiles against a resilient mat to produce simulated concave joints between adjacent tiles.
  • the casting box described in Kastenbein is custom built for this particular purpose and, in order to allow use of high vacuum, isquite massiveand expensivein construction.
  • Kastenbein of Tile Council of America, got by without seaters because he was primarily dealing with 4 inches X 4 inches quarry or bathroom tile, glazed in most cases, made under very controlled factory conditions where highquality control standards exist and where each and every tile is individually inspected for warpage-before being packaged.
  • a casting box having at least one vacuum line connection through its "floor with a laminated insert plate which includes a resilient upper layer provided with one vacuum line opening-for each slab, and which incorporates conduits extending from the openings to communication with the casting box floor.
  • mentgrid having individual cells for receiving individual slabsis received in the casting box on the insert plate upper layer.
  • a heavy seater is lowered onto the slabs to force them into sealing contact with the insert plate resilient upper layer and a vacuum is drawn through the casting box floor to hold the slabs so tightly against the insert plate resilient upper layer that the layer bulges up between adjacent slabs.
  • the seater is removed; then the placement grid is withdrawn with the assistance of removable lateral shims and a settable composition such as concrete is poured into the casting box upon the slabs.
  • the panels so formed have slabs set therein with simulated semi-flush concave joints.
  • a 'modified device for production of panels faced with slabs on both sides is also disclosed.
  • the teaching of the present invention makes possible the rapid and reversible conversion of present day unfaced casting beds and forms to faced casting beds and forms with practically complete utilization of all components of the former and without in any way damaging said components or preventing their rapid change back to their original use.
  • the vacuum plate inserts of the invention have such very limited unsupported spans that have to resist the forces generated by relatively high vacuum that relatively inexpensive inch plywood can be utilized as core plates, those having more than the needed strength required to prevent any undesirable flexure. Regardless of whether the vacuum bed covers 1 square foot or 200 square feet, the areas unsupported by sponge rubber sheet on either side of thevacuum plate inserts stay the same for any given facing material and are always minimal.

  • a panel casting system 10 including a casting box 12, which receives a vacuum plate insert 14, upon which brick slabs B are placed face down using a removable placement grid 16 to achieve conformity to the desired array pattern.
  • the slabs are sealed against the vacuum plate insert with the aid of a heavy seater 18, a vacuum is drawn through the vacuuni 'plate insert 14 to maintain the slabs sealed against the insert and to elastically distend the insert so that it bulges up between adjacent slabs.
  • Concrete or other settable backing C is then poured into the box over the slabs, screeded off and allowed to set.
  • the panel P when removed from the box' includes a face F of brick slabs B provided with a simulation of semiflush concave joints J between adjacent courses of slabs and between adjacent slabs in the same course.
  • the desired panel P is to be independent and approximately 8 feet 6 inches in height and 10 feet 0 inch in width, X (2 A inches as inch) it; inch determines that our panels would be I02 34. inches, or 39 courses high, (39 (2 inches inch) inch) and 117 it; inches or l4 br'ick wide, (14 (8 inches as inch) inch).
  • Anfindependent panel is'one that is complete by itself, one that does not have to carry on joint work that was started in a previous panel, or one that is initiating joint work that its adjoining panel is to carry on with.
  • An independent panel using inch joints is it; inch higherand it: inch wider than a carry on panel and it; inch wider than a starter panel as its brickwork is completely surrounded by inch joints, not just on one side or just on either the top or bottom, but on both.
  • the form cavity 20 in the casting box 12 for this panel will be the exact required dimensions, namely,
  • the vacuum pad insert 14 basically includes a flat inch, V2 inch, or We inch steel plate, or inch, /2 inch, inch or inch sheet of plywood 26 cut to an exact 102 inches X I17 inches, minus 1/32 inch all around.
  • Each half and each full brick slab B to be used on the bottom face F of these panels P is laid out on this insert 26 and on the geometric center of each is drilled a 7/16 inch hole 28 through the sheet 26, (one that could be tapped out to k inch for fill in" purposes later on if required, or for the insertion of lifting eyebolts).
  • this vacuum plate insert Around the bottom edge of this vacuum plate insert is glued 2 inches wide X inch thick strips 30 of medium sponge rubber. Also on roughly 5 inch X 4 inch centers, 4 inch by 3 inch pads 32 of the same sponge rubber are glued but not to cover the vacuum access holes 28.
  • a complete covering 34 of inch closed cell sponge rubber sheeting which has previously had slot cutouts 36 made in it to match the 7/ 16 inch holes provided in the steel plate or plywood sheet 26.
  • These cutouts are approximately inch X 5 inches for each full brick and are set on the geometric centers of where these are to be located, and inch X 2 inches for each half or header brick, also on the geometric centers of where these are to be located.
  • the casting table bottom plate 22 is drilled and tapped at 38 for several vacuum lines 40, all of which spread out from a single fast action control valve 42.
  • the vacuum plate insert 14 with its sponge rubber borders 30, pads 32 and covering 34 is lowered into the form cavity 20 where it seats itself on the casting table bed plate 22. 4
  • the vacuum plate insert 14 is not only one of the keys to system l0s success, but it makes vacuum gripping practical for the first time. As conceived and practiced, vacuum can be applied to an unlimited area without creating even a semblanceof warpage or strain on the containing surfaces.
  • the bottom rubber backing strips 30 and pads 32 absorb the forces which might otherwise be spent in warping or buckling any or.all containing surfaces.
  • the vacuum plate insert 14 because it is an independent unit, and a relatively cheap one, that can be fabricated in just a few hours, is one key to a versatility that can be extremely beneficial. Such vacuum plate inserts 14 can be used with practically any and all of the conventional casting beds 12 now in existence, which means that established panel producers can change over to the system 10 at a very minimum of expense.
  • the remainder of the vacuum generating system shown in FIG. 1 is made up of standard elements which are believed adequately explained by captions in the figure.
  • the system benefits from the use of a relatively large accumulator 44, so one can use a reasonably sized vacuum pump 46.
  • the accumulator allows one to exhaust all the lines and the open areas of the vacuum plate inserts almost instantaneously without but a very small and easily acceptable loss in the degree of vacuum held as a minimum.
  • the step following installation of the insert 14 in the casting box 12 is installation of the placement grid 16, which is lowered down onto the top of the sponge rubber top covering 34 and which contains positive locating edges for all the full and half slabs B needed to face the panel P.
  • This grid is preferably constructed so that all of its locating surfaces are to the left and to the bottom.
  • the grid 16 itself preferably offers a reasonable clearance for each brick to be inserted in its cells 48.
  • the grid is made of A inch X if inch horizontal and Ya inch X if inch vertical cold finished bars, the space available to insert 2 inches X 8 inches brick slabs is 2 inches X 8 54 inches which covers very wide size variations among the individual brick.
  • the grid 16 should be about one-fourth inch less in height than the thickness of the slabs B to be used. Thus, a grid for 1 inch thick slabs should be threefourths inch in height. Slabs should stick up above grid one-fourth inch, so that a sponge rubber lined, flatbottomed seater 18 can effectively contact the backs of the slabs and yet miss the top of the slab locating grid 16.
  • the A inch differential cannot be increased very much without the possibility of ending up with the grid being locked in place by slab edges, that, due to slab deformities or tilt, just slightly overhang the ribs of the grid. It would, for instance, probably be impossible, a significant percentage of the time, to remove a inch high grid in use with 3 inches high full size brick even with the float provision later described herein.
  • Regular vertical grid ribs should not exceed A: inch material unless very, very uniform sized slabs are going to always be. available.
  • the length of the grid void spaces will be A inch greater than the nominal length of the slabs, inch joint assumed and 8 inches long brick if; inch :6 inch),
  • One-fourth inch stock can be generally used for horizontal grid ribs 52 for brick slab heights rarely vary even 1/16 inch over average size.
  • Removable Vs inch flat metal spacers do provide a means of freeing grids from 'the two-way build up of side pressures by releasing the grids and allowing them to be lifted out without difficulty.
  • Such flat spacers can present their own removal problems. If these flat spacers do not protrude up and above the sides of the molds a sufficient distance to allow them to be firmly grasped by hand or with pliers or other suitable tools, they, themselves, can be extremely difficult to remove. If they do extend up above the casting box sides for easy insertion and removal, then they can be easily hit by and badly damaged by the heavy seaters as they are swung into place and lowered down into the casting box. One-eighth inch flat steel strips cannot stand up to a swinging mass weighing up to five tons or better. Thus, the alternate use of screws to make possible an easy and positive way to exactly locate and then later release placement grids is the preferred means.
  • cap screws can only be withdrawn the exact amount needed to leave their ends flush with the interior sides of the casting box.
  • a inch stock in conjunction with easily installed or removed is inch spacers 56 (FIG.
  • the use of such spacers permits one to attain the equivalent of zero installed clearance between the sides of the jigs (placement grids) and the sides of the casting form, thereby insuring correct and thus reproducible slab placement as well as providing a means of attaining some side to side and top to bottom float after the slabs have been gripped, by removing the spacers.
  • This float is achieved by use of left vertical and bottom horizontal ribs with spacers 56, and is one 'of the real keys to most. successful use of the locating grids.
  • the spacers 56 are in the form of short L shaped channels'removably received in slots 57 formed in the top and exterior of the left-most and bottom outside grid elements. The float one obtains in both directions not only makes it possible to lift out the grid prior to pouring, but to do it easily, even in spite of the tilt and slab deformity problems that generally exist.
  • top and bottom are sometimes used herein 'to denote orientations which would be correct for the casting systemonly if it were tilted up to match the orientation of the panel P when the panel becomes part of a wall. Actually, of course, the casting is usually carried out horizontally. Thus the terms are used in the sense of convention, and not necessarily in the sense of actual spatial orientation.
  • the flush concave joint I that is obtainable with the system 10, is of course a result of the high vacuum employed creating sufficient pull to displace a sufficient amount of the vacuum plate insert sponge rubber facing 34 and causing same to bulge into the void joint areas to give a concave outline in the same.
  • the typical slab placement grid 16 which provides two like edge contacts for each and every slab B is the ultimate. Any laborer, who places slabs in such a grid, does not have to waste any time or effort or exercise any special skill or judgment to properly adjust the spacing or alignment of any slab. All anyone has to do is place successive slabs in empty grid cells and to move each slab as far as possible to the left and keep same down adjacent to and in contact with the horizontal ribs. With this type of positioning grid one can easily set and position slabs even while blindfolded.
  • the slabs themselves are floatable in that they offer but very slight resistance to the very slight displacement that may be necessary to free a lock-in of the grid.
  • the slabs are just about unmovable, and grid lock-ins can be real serious. If there are any projections of slab edges over both left and right vertical ribs, then the grid just cannot be lifted out. Any built-in float produced by the use of spacers, or other means, is simply ineffective in such a situation.
  • Removable float producing spacers 56 can only be effective when slab contact with vertical ribs is either always to the left, (or to the right, if the spacers are positioned to the right), and when slab contact with the horizontal ribs is always at the bottom, (or to the top if the spacers are positioned at the top). Float can only be effectively achieved when slabs and spacers are so located that the removal of the spacers automatically makes it possible to shift the grid horizontally and vertically so that it at once loses contact with the slabs and is therefore verti cally removable with ease.
  • Slab locating grids can also be more economically constructed if simple short pins are substituted for complete vertical ribs 50. It is a relatively simple. task to gang drill and then machine tap required holes for such locating pins which are threaded on one end.
  • the next operation following placement of the brick slabs in the grid cells 48 is to lower down onto the backs of all the brick B in the individual cells 48 the seater 18 having a flat pad 60 that is just a bit smaller than the panel to be poured and having a semi-soft rubber facing 62 and having a fairly equally distributed weight equivalent of about 25 pounds per full brick in the panel. It has been found that even soft sponge rub ber if used for the inserts or face 34 offers enough deformation resistance to prevent thet gross weight of a rough faced brick or brick slab from making a usable seal, that is, make enough of a seal with the vacuum plate insert 14 to permit .a vacuum to be readily achieved. r
  • the seater 18 When relatively thin brick slabs are to be used as facing material, it is necessary that the seater 18 have on its base side protruding and spaced pads 60', each faced with suitable sponge rubber facings 62'. These pads should be at least one-half inch smaller both ways than the slabs they will contact and preferably about as thick as the grid is high. This is necessary so that the seater can contact each and every slab even though that slab actually is only as little as one-third in thickness, the depth of the grid opening.
  • the seater 18 is preferably a heavy, cast, cranemovable body as depicted in FIG. 1, but the pad 60 and facing 62 could be provided on a ligher element constructed to be forced down against the slabs, for instance by hydraulic ram means.
  • the vacuum valve 42 is opened, and the slabs B are literally grabbed by the vacuum.
  • the vacuum plate When panels are being faced with very thin and therefore quite fragile brick slabs and/or very rough faced slabs, some minor problems may be experienced with vacuum leaks.
  • the vacuum plate By arranging the vacuum plate inserts support layer of sponge rubber, so as to divide up the panel s exterior face into several more or less equal divisions areawise, and by separately piping gauged vacuum lines with individual valves to each such division, one can easily and quickly pinpoint where a broken or impossibly rough faced slab or slabs are located.
  • the faultless sections can be held on vacuum while the troublesome area is shut off, the seater raised out of the way, the faulty slabs replaced, the seater returned and the vacuum again turned on.
  • the seater 18 is then raised and carried over to the next panel (if an assembly line operation is being employed) or put in storage.
  • the incipient panel is next checked for brick alignment, the grid 16 removed, and the panel backing then poured, screeded and finished.
  • the backing may be any conventional settable construction material such as cement or a synthetic plastic substitute
  • the seater may be the simplest unit in the system 10 of panel making it is nonetheless important. Without a seater it is doubtful one could ever get a 4 feet X 8 feet, or larger panel '5 complement of slabs sufficiently in contact with the foam rubber surface of a vacuum plate insert to create a vacuum seal excepting when uniformly smooth, probably glazed, slabs are used. A seater 18 actually takes the place of hundreds of non-existent hands, without which the system 10 would be impracticable. for use with most slabs.
  • a typical closed cell sponge rubber to use for the sponge rubber layers of the vacuum plate insert and the seater is manufactured by Rubatex.
  • the casting box may be used horizontally, it may be tipped to an upright condition during the panel manufacturing process, for instance to facilitate removal of the completed, hardened panel.

  • the round core holes in such brick are about 1 inch in diameter' and always have one such void at the midpoint in each brick horizontally and vertically.
  • the 1 inch diameter of such core holes insures both the easy threading of 54 inch round steel through multiple courses top to bottom of a panel and the total encasement of the steel in mortar of more than sufficient thickness around same.
  • the modified casting equipment for producing reinforced panels is identical to that for the system as depicted with the exception of the bottom or top casting box side wall, which would, at appropriate points along its length, have inch holes drilled and be supplied with suitable flush plugs to fill said holes when they are not being used.
  • the V4 inch round vertical reinforcing rods would be passed through these holes when being inserted into their respective vertical row of the bricks center core holes. These holes would be drilled on the center line of the vertical reinforcing rods location and have their centers 3/ 16 inch above the centers of the brick core holes the rods are to be enclosed in.
  • the flush plugs will always be in place except when the rods are being inserted.
  • the casting box includes a level surface, the bottom of which would be piped at several locations to a common manifold the manifold would be capped on one end and fitted with a suitable valve at the other end this valve in turn would be piped to a suitably large vacuum accumulator tank which in turn would be piped to a vacuum pump of suitable capacity.
  • Four side forms of sufficient length would be fastened to the base 6 plate so that their'interiors would enclose the exact area of the desired panel to be cast.
  • the bottom or top side form would be suitably drilled and furnished with flush plugs for the insertion of the vertical reinforcing steel in between first and second pours.
  • a suitable vacuum plate insert would be placed in the casting area.
  • Draping simply consists of hooking a preformed wire tie down under the vertical rods, bringing the looped ends up and bending each one over the corners of its brick on opposite sides of the joint void into which the horizontal reinforcing rod will be inserted.

Then a fluid, hardenable composition is poured into the mold so created and allowed to harden. The vacuum is then released and the mold opened to provide a two-faced panel with semi-flush concave joint simulations as shown in FIG. 9.
  • System 10 is an answer to the demanding need of a method that will permit facing of both sides of individual panels with the ease, quality of jointwork and clean faces that can be achieved with system 10' for single faced panels, (vacuum gripping and top pour).
  • the equipment needed to use this alternate system 10 is a pair of horizontal, opposed and hinged precast panel forms 12 that are fitted with suitable vacuum plate inserts 14, along with matching slab placement grids 16 with releasing shims or screws, an appropriate seater 18, and a vacuum pump (FIG. 1) 46 with a large accumulator 44.
