Definitions
- the invention relates to a support frame composed of individual parts made of ceramic material for supporting ceramic tiles and such objects to be fired in an oven, provided with a number of stackable rectangular frames, the vertical side walls of which have projecting horizontal support strips on the inside and outside, and with them horizontally extending coupling plates, which each have a pair of frames placed one on top of the other and at the same time with a pair of frames which are preferably at a distance equal to the clear width of the frames in the longitudinal direction of the supporting frame and thus have at least one corresponding complex of spaced apart in the transverse direction of the supporting frame detachably connect two stacked vertical pairs of frames.
- the invention aims to provide a tile support frame of the type mentioned which does not have the disadvantages of this known support frame and which is quick and stable. Construction of the support frame made of easy-to-manufacture lower parts.
- each frame has vertically projecting support cams on the underside and on the top, by means of which the stacked frames are supported on one another, and that each coupling plate is arranged and close between the frames of each stacked frame pair to be coupled by this plate is provided on its side edges with holes, each accommodating two supporting cams supporting each other, the thickness of the coupling plate being smaller than the total height of two supporting cams supporting one another.
- the support cams preferably form extensions of the frame side walls.
- This design makes it possible to regrind the support cams to the desired length after the manufacture of the frames, for example by first giving the support cams a somewhat too long length. After the grinding process, all frames have exactly the same, total height, so that when the frames are stacked, no significant height differences can occur due to the list of unfavorable manufacturing tolerances.
- the coupling plates which enclose the support cams with the holes provided therein and prevent mutual displacements in the horizontal plane, do not influence the stacking height of the frames, because their thickness is less than the total height of the support cams which are supported on one another.
- the clutch plates are therefore not pinched but retain limited freedom of movement.
- the coupling plates are preferably provided according to the invention with vertical webs lying in the planes of the frame side walls of the coupled frame, each of which opens the frame at least on one side in the transverse direction. These webs are preferably located on the same side of the coupling plate, where they connect to the holes in this plate. Normally, in the composition of the support frame, the webs are directed upwards so that they enclose the frames on the underside, while on the top of the stack of frames the coupling plates can be arranged upside down, therefore with the webs pointing downwards.
- the support frame of FIGS. 1-6 is composed of loose stackable frames 1 and coupling plates 2 connecting these stacked frames, thus coupling elements 3 and 4 provided at the ends of the support frame.
- These frame elements 1-4 are made from a refractory ceramic material known per se.
- the support frame is supported by means of support blocks 5 made of the same material on the upper side 6 of a tunnel kiln car (not shown), in FIG. 1 the one end of the support frame is shown which extends on the left side of this figure over an arbitrary length.
- the frames 1 are of identical design and, viewed in the transverse direction of the support frame, have a small width in comparison with their length and height measured in the plane of the frame.
- Each frame consists of two side bars 7 forming the frame side walls, which are connected on the upper and lower sides by an upper bar 8 and a lower bar 9.
- the frame side beams 7 are provided on the inside and on the outside with equally spaced support strips 10 and 11, which run obliquely sideways and upwards at a small angle at the top and which serve to support the pavement tiles 24 to be burned in the tunnel kiln (Fig. 5).
- the frame side bars 7 continue for some distance above the upper frame bar 8 and below the lower frame bar 9 to form the same upper support cams 12 and lower support cams 13, as shown in FIG. 5.
- the support cams are first given a somewhat too large length at least on one side of the frame, whereupon these cams are sharpened exactly to the correct extent, such that the height dimension of each frame between the lower surface of the lower cams 13 and the surface the upper cam 12 measured exactly corresponds to a certain value. In this way, differences in shrinkage are compensated for in the manufacture of the frames and none when stacking the frames significant height differences occur between adjacent frame stacks.
- a number of e.g. four or more frames 1 with their cams 12 and 13 stacked on top of each other and these frame stacks are arranged in longitudinal rows more arbitrarily, determined by the dimensions of the tunnel kiln car, the distance between two frame stacks of the same longitudinal row corresponding to the clear width of the frame openings, so that also the outward facing support strips 11 of two successive frame tiles 12 can be supported.
- FIG. 1 a number of e.g. four or more frames 1 with their cams 12 and 13 stacked on top of each other and these frame stacks are arranged in longitudinal rows more arbitrarily, determined by the dimensions of the tunnel kiln car, the distance between two frame stacks of the same longitudinal row corresponding to the clear width of the frame openings, so that also the outward facing support strips 11 of two successive frame tiles 12 can be supported.
- the frame stacks are arranged in four adjacent longitudinal rows, such that in the transverse direction two adjacent frames 1, separated by a narrow gap 14, form a pair of frames which carries a vertical row of tiles 24, while this pair of frames is separated from a second pair of frames for supporting a second vertical row of tiles by a central opening 15 of greater width.
- the columns 14 promote a good circulation of the hot air along the tiles when they are burned in the tunnel kiln. In the event that the width of the tunnel kiln car permits this, further longitudinal rows of stacked frames 1 can of course be placed next to one another on the car.
- the stacked frames 1 are held together by the coupling plates 2 in the correct mutual positions. These coupling plates extend over the entire width of the support frame and have holes 16 at a short distance from their side edges (FIGS. 3 and 4) into which the cams 12 and 13 fit.
- the thickness of the clutch plates 2 is slightly less than the total height of two supporting cams 12, 13 which are supported on one another, so that when a clutch plate 2 is arranged between two stacked frames 1, the cams 12 and 13 of which are each in a hole 16, the clutch plate rests on the the upper bar 8 of the lower frame 1 but is exposed from the lower bar 8 of the upper frame 2 (Fig. 5).
- the coupling plate 2 in this way holds the support cams 12 and 13 together in a non-displaceable manner but does not influence the overall height of the stack. On the other hand, the coupling plate 2 still has sufficient freedom of movement to deviate from the horizontal position, e.g. if the stack height of an adjacent frame stack would be somewhat different due to an irregular supporting surface for the supporting frame.
- a total of eight holes 16 are provided in pairs in the coupling plate 2 such that the coupling plate can connect a total of sixteen two and two stacked frames 1 of four longitudinal rows extending next to one another.
- the support frame of the design described above can be assembled in a simple manner.
- the lower clutch plates 2 are supported on the support blocks 5, which are provided on their upper side with similar vertical cams 12 'as the frame 1 (Fig. 2).
- the uppermost clutch plates 2 naturally only take up the cams 12 of the uppermost frames 1.
- coupling elements 3 are used which have only one row of holes 16 and which are obtained by cutting through a coupling plate according to the dashed line 17 of FIG. 3.
- the remaining part forms a coupling element 4, which is placed on the support blocks 5 at the end of the row.
- the coupling plates 2 are further provided with upstanding flat webs 18 and 19 which connect to the elongated holes 16 and form a lateral support for the vertical frame side bars 7 of the frame 1.
- the webs 18 are located at the two ends of the coupling plate 2 and support the two outer frames of the two pairs of frames lying next to one another in the transverse direction, while the middle web 19 extends through the opening 19 and supports the two inner frames of these pairs of frames.
- the uppermost coupling plates 2 of the assembled support frame are reversed, that is, with their webs 18 and 19 directed downwards.
- Ventilation holes 20 are also provided in the clutch plates 2.
- the webs 18 and 19 increase the stability of the support frame. If desired, a further stiffening can be obtained by inserting a fitting wedge 21 into the column 14 between the side beams of each pair of frames, as was drawn at one point in FIG. 2.
- the frame beams 7 and the fitting wedges 21 are provided with interlocking projections 22 and recesses 23 which hold the fitting wedges 21 in position (cf. also FIG. 6).
- Such a frame may then, for example, have a width equal to or slightly smaller than the total width of a horizontal transverse subframe pair with the inter-frame whose column 1. 4
- FIGS. 7 and 8 show an embodiment of a support frame for supporting ceramic paving tiles or bricks of larger size to be fired than the wall tiles 24 in the support frame of FIGS. 1-6.
- paving tiles In order to achieve a greater density, such paving tiles generally also contain a larger glass content and are fired once, in which they are to be supported over their entire surface by ribbed support plates 25 so that the tiles do not sag.
- FIG. 7 and 8 has essentially the same structure as the first described support frame of FIGS. 1-6 and again consists of frame 1 and coupling plates 2.
- the vertical side beams 7 of frame 1 in this case have relatively short support strips 26 protruding on both sides , 27 with horizontal tops and oblique corners, on which support strips the tile support plates 25 for the paving tiles 28 to be fired rest.
- Fig. 8 seen in the transverse direction of the assembled support frame - the tile support plates 25 of two supported at a relatively large distance from one another frame 1, the support plates still protruding on both sides of this pair of frames.
- four or more pairs of longitudinal rows of stacked frames 1 can be placed side by side on a tunnel kiln car not shown in FIG.
- the coupling plates 2 are connected in a corresponding manner as described above by means of coupling plates 2 extending over the entire width of the supporting frame.
- the coupling plates again have holes 16 into which the support cams 12 and 13 of the frames 1 stacked on one another fit.
- the coupling plates 2 are provided with vertical webs 29 which extend between two frames 1 of a pair of frames supporting the same tile supporting plates 25 to improve the transverse stability of the supporting frame.
- support webs of this type it is also possible to use support webs of this type as the webs 18 and 19 of the coupling plate 2 in FIG. 3.
- a support structure can be used which is constructed from the lower parts shown in FIG. 9.
- This support frame again has a number of longitudinal rows of frame 1, which have the same design as the frame 1 described above and therefore again with upper and lower support cams 12 and 13 and with inner and outer horizontal support strips 10 and 11 (only a few of which are shown ) are provided.
- the frames 1 of the same longitudinal row are again arranged at a distance from one another equal to the clear width of each frame.
- the frames 1 of, for example, two (or more) longitudinal rows are connected by coupling plates 30, which are comparable to the coupling plates 2 described above and have slot-shaped holes 16 for receiving the cams 12 and 13 of the stacked frames 1 in a similar manner as described above.
- a series of support elements 31 is arranged, which are directed transversely to the frame 1 and whose vertical side walls are provided with laterally projecting horizontal support strips 32, which are the same Form as the support strips 10 and 11 of the frame 1.
- These support elements 31 also have support cams 33 on the upper side and support cams 34 on the underside, which are comparable to the support cams 12 and 13 of the frame 1.
- each support element 1 is located in the middle between two successive vertical side walls 7 of the two rows of frames 1 in such a way that the elongated wall tiles 35 to be supported are supported in three positions in the manner shown, namely on their two long sides by means of the supporting strips 10 or 11 of the respective frame side walls 7 and at one short end side by means of a carrier - bar 32 of the support element concerned 31.
- the support members 31 may, as the frame 1 are stacked vertically, and the elements are slotted holes 36 and 36 thereby ' are provided plates 30 and can take up the supporting cams 33 and 34 of two towards each other ab limbander support members 31 - held transversely to the slit holes 16 in the clutch.
- the slotted holes 36 ' which are to hold 1 supporting elements located 31 in the transverse direction of the support frame between two opposite frame are in a tra - pezförmigen laterally projecting part 37 of the clutch plates 30 is formed which protruding part 37 in a corresponding recess 38 in the opposite side edge of the inserted into the next coupling plate 30 and overlaps and rests on this next coupling plate with an upwardly bent edge part 36.
- the coupling plates 30 also cause the frames 1 and supporting elements 31 stacked on one another to be held together in a stable manner. If the support elements 31 have a small width in the transverse direction of the support frame, they can also be solid, so that the frame opening of these elements shown in FIG. 9 then fails.
