    Title: Refractory lining for a pipe wall of an incinerator
    DESCRIPTION
    The invention relates to a refractory lining for a pipe wall of an incinerator, comprising: a number of ceramic tiles placed next to and on top of each other of refractory tiles, which at the rear, which faces the pipe wall, are provided with a vertical insertion channel; a holder for each tile, wherein the holder is provided with an anchor which is connected to the pipe wall and wherein the holder, when mounted, extends substantially perpendicular to the pipe wall and partially into the plug-in channel, a free space between the tiles and the pipe wall space is formed, which is filled with a hardening casting compound.
    The refractory lining according to the invention is adapted to be applied to pipe walls of (waste) incinerators, to prevent corrosion of the metal parts by flue gases and to enable high furnace temperatures without thereby weakening or cracking the metal pipes due to high local temperatures .
    The pipe wall is formed by welding pipes, vertically aligned next to each other, to each other by means of fins or connecting strips / dams so that a closed gas-tight oven is formed. During use of the furnace, water and / or steam flows through the pipes, which absorb the released heat of combustion. Such coatings are known from EP 2388521 and EP 1032790. The purpose of the coating is to extend the service life of the incinerator and to reduce failure and (expensive) repair of the pipe wall.
    In current incineration plants, the pipe walls and linings are often exposed to temperatures above 1000 ° C and more, so that due to the large temperature differences, expansion and contraction will occur in the pipe wall and the lining.
    The coating is formed by a wall of shaped bodies, hereinafter referred to as tiles, of ceramic material. The tiles are placed next to and on top of each other to form a protective covering wall for the pipe wall. The tiles are provided with a vertical insertion channel on the side of the pipe wall so that the tiles can be slid onto holders and fixed - or hung - on the pipe wall. The holders are provided with an anchor, whereby the end of the anchor can be welded to the connecting strip between the pipes. The welding process that is preferably used for this is called pin welding or bolt welding (Stud welding). In the mounted state, the anchor extends substantially perpendicularly to the surface of the pipe wall. The anchor is usually formed as a screw bolt on which a nut is mounted as a head.
    A joint material such as a strip of felt is preferably applied between the tiles. The felt is preferably glued between the tiles, for example with a quick-drying spray glue. The felt serves to accommodate the expansion of the tiles and thereby reduces the risk of the tiles cracking as a result of expansion or shrinking during operation. After one or more horizontal rows of tiles have been piled up and hung against the pipe wall, a hardening casting mass is introduced into the free space between the tiles and the pipe wall (also known as a rear casting joint), such as for example a concrete mortar. When the casting mass has cured, the lining is ready to protect the pipe wall against the high temperatures and the flue gasses during operation of the incinerator.
    There are a number of drawbacks to the above-mentioned known refractory coating.
    Horizontal and vertical alignment of the tiles is time-consuming in that each time the nut has to be screwed onto the anchor of the holder by rotation and must be adjusted to the desired position of the tile.
    In order to obtain good heat transmission through the lining to the pipe wall during operation of the furnace, the thickness of the cured casting mass must be as small as possible and therefore the free space between the tiles and the pipe wall must be as thin as possible. However, if this free space is too thin, the casting mass will not be able to flow out properly and zones will be formed in the free space with little or no casting mass, as a result of which the tiles are not properly supported on site and moreover hot combustion gases may come into direct contact with the pipe wall. It is therefore essential that the thickness of the free space can be adjusted optimally and accurately, within narrow margins, during the construction of the clothing, so that an even, homogeneous, cured casting layer of the desired thickness is obtained.
    With the known cladding it is very time-consuming to properly align the tiles horizontally and vertically and at the same time to provide the free space with a predetermined optimum thickness.
    The known coating has the disadvantage that the risk of pressing the joint material out of the joints is great, as a result of the hydrostatic pressure during the pouring of the concrete mortar into the free space between the tiles and the pipe wall. The known cladding therefore also has the disadvantage that a maximum of two rows of tiles can be built up and provided with concrete mortar, because when filling the free space behind three or more rows of tiles the risk of squeezing the jointing material at the bottom row of tiles is reduced. becomes large, so that mortar runs into the joint, and the chance of the tiles breaking during operation increases considerably. Moreover, even tiles of the anchoring are pressed by the hydrostatic pressure with simultaneous casting of three or more rows of tiles.
    The object of the invention is therefore to provide a refractory lining for a pipe wall of an incinerator, which can be assembled, supplemented and repaired more easily and quickly, and which is provided with a homogeneous cured casting mass with an optimum thickness, and wherein the risk of damage during use to the lining and the pipe wall is greatly reduced.
    These objects are achieved in that the invention provides a (covering) spacer, which is provided between adjacent side ribs of four refractory tiles.
    By placing (covering) spacers between the adjacent (width) side ribs of four tiles, the tiles are aligned both horizontally and vertically. In addition, the spacer prevents the joint material from being pressed from the horizontal and vertical joints between the tiles by the casting compound or even tiles are pressed from the holders. By using the spacers according to the invention, three or more rows of tiles can be built up, so that at the same time the free space between the three or more rows of tiles and the pipe wall can be filled with concrete mortar. The spacer is a so-called lost material, it already burns at low temperatures during use of the oven.
    The spacer is preferably provided with a front wall, a rear wall, and a flat body, the flat body extending between the front wall and the rear wall. Such a spacer can easily be placed on a refractory tile and also provides a good horizontal and vertical alignment of the refractory tiles placed next to and on top of each other.
    At least the front wall is preferably provided with a clamping edge formed by the flanged horizontal top edge of the front wall. In particular, the front wall is provided with a second clamping edge, formed by the flanged horizontal bottom edge of the front wall. By arranging clamping edges, the spacer can be clamped onto the tiles so that the spacer will not shift quickly or even come loose and fall during the placement of a new row of tiles when building up the lining of the pipe wall in the incinerator. In addition, the spacer secures the tiles from falling out due to the hydrostatic pressure of the concrete mortar.
    The flat body is preferably provided on its underside with at least one rib which extends parallel to the front wall and the rear wall. More in particular, two or more parallel ribs are provided on the flat body of the spacer. By applying these ribs, the required and desired joint height between the tiles is obtained in a simple manner, and this also prevents the horizontal joint material from shifting or being displaced between the tiles.
    An alternative embodiment of the invention is characterized in that the spacer on the rear wall is provided with an arm element. The rear wall of the spacer is preferably provided with a coupling element for an arm element. In particular, the coupling element comprises an elongated groove or two elongated groove parts which extend horizontally. Thanks to these measures, the spacer can also contribute to - simultaneously with the horizontal and vertical alignment of the tiles - realizing an optimum free space between the tiles and the pipe wall. By providing a coupling element to the spacer for attaching an arm element, the distance between the tiles and pipe wall can be adjusted to a predetermined and desired distance in a simple and inexpensive manner. Because the arm element exerts a repulsive force on the tile relative to the pipe wall, the tiles will be pressed with their insertion channel against the underside of the head of the holder, so that the tiles are positioned at a distance from the pipe wall, which is determined by the length of the applied head bolt. Due to the obtained fixed distance between the pipe wall and the tiles, the often occurring deformations in the pipe wall can be followed well and the free space is optimal everywhere.
    The refractory lining for a pipe wall of an incinerator according to the invention can be provided with a one-piece holder, such as for example a head bolt. In particular, for the characteristics of the head bolt one or more is selected from: a head with flattened sides; a head with rounded undersides; a rejuvenated neck section between the head and the anchor; a smooth anchor; the cross-sectional area of the anchor is substantially the same as the cross-sectional area of the neck section.
    The rounded round shape of the underside of the head provides for a larger contact surface with the insert channel of the tile relative to the flat nuts, so that notch effect is prevented as a result of line / point contact with the inside of the insert channel with (hydrostatic) loading during assembly or due to deformation of the tiles during operation.
    The rejuvenated neck section makes mounting the tiles easier because there is more freedom in the horizontal direction when placing the tiles.
    A smooth anchor has a 40% higher strength than a threaded rod of the same diameter, moreover a smooth anchor is more resistant to chemical attack due to the smaller specific surface. Maintaining the surface of the cross-sections of the neck section and the anchor substantially the same produces a bolt on which a tile can easily be placed, but which has no weakened parts or sections.
    In a special embodiment, the refractory lining is provided with a wedge element in the insertion channel of the refractory tiles near the holder, the wedge element being adapted to optimally position the tiles on the holder.
    In particular, the wedge element comprises a channel body, provided with a wedge part and with a slot body.
    By inserting the tapered wedge part of the wedge element into the space between the top of the holder and the inside of the plug-in channel, the (rounded) undersides of the holder are pressed against the round inside of the plug-in channel, so that the tiles are optimally pressed. be positioned at the desired distance from the pipe wall. Moreover, the wedge element according to the invention is always inserted into the insertion channel in the correct manner (except when it is inserted upside down).
    In a special embodiment for the purpose of repairing or supplementing or adding to an existing refractory lining, an insertion opening is provided in a refractory tile and a dip element is provided in an insertion opening of the tile, the tile with the clip element being clicked onto the holder.
    In particular, the clip element is a V-shaped click element, which comprises two clip wings which are connected to each other on their base side and which are provided on their upper sides with a support lip and with a hook lip .
    The two clip wings of the clip element are preferably provided with openings adapted for receiving and clamping insert parts of the holder.
    The openings in the clip wings of the clip element are in particular provided with engaging means such as teeth.
    The repair tile is of great advantage when a new piece of cladding has to connect to an existing part or when a tile of the refractory cladding has to be replaced. By using a clip element with the advantageous features according to the invention in an insertion opening of a tile, the tile can simply be clicked onto a (displaced) tile holder without sliding, wherein the tile is positioned optimally in line with the adjacent tiles. the holder. The tiles can be prefabricated with an insertion opening, but the insertion opening can also be provided later, for example by drilling. When the tile (s) must be applied to an existing tile holder (s), one (or more) new insertion opening is usually made to measure in the insertion channel of the tile.
    The invention also relates to a method for assembling and building a refractory lining for a pipe wall of an incinerator comprising the steps of: arranging a number of holders on the connecting strips between the pipes of the pipe wall; placing a number of refractory tiles next to each other in a first horizontal row with the vertical insertion channel on the holders; placing the spacers between two tiles on adjacent side ribs.
    In particular, the method also comprises the step of: placing a second horizontal row of tiles on the first horizontal row of tiles, such that a spacer is provided between the adjacent side ribs of four refractory tiles.
    More in particular, the method also comprises the step of: inserting a wedge element into the space between the top of the holder and the inside of the plug-in channel.

    Figures 1A-1B show an embodiment of the refractory lining 1 for a pipe wall 2 of an incinerator according to the invention. The pipe wall comprises a number of parallel pipes 4, which are mutually connected by means of fins or connecting strips / dams 5, so that a closed wall is formed. During use of the incinerator, a medium or fluid flows through the pipes, which is suitable for absorbing heat from the incinerator. Water and / or steam is usually used as the medium. The covering 1 is formed by a number of refractory tiles 3 of ceramic material placed next to and on top of each other, which at the rear, which faces pipe wall 2, are provided with a vertical insertion channel 10. The connecting strips 5 are provided with holders 7 on which the tiles 3 are hung or with which the tiles are attached to the pipe wall 2. In this exemplary embodiment, the holders 7 are provided with a head 9 and with an anchor 8 with which the holder 7 is welded to the connecting strips 5 between the pipes 4, for example by pin welding. In the assembled state, the holders 7 are substantially perpendicular to the pipe wall 2. For the head 9, a screw head or nut can be used, or a fixed head can be formed so that the holder is a so-called one-piece head bolt.
    Figure 2B shows the rear side - the pipe wall side - of a refractory tile 3 in more detail. Figures 2A and 2B show that the tile 3 is provided with a plug-in channel 10, into which the holder 7, in particular the head 9, can be inserted. The insertion channel 10 is provided on its rear side - the pipe wall side - over its entire length with a narrow open connecting slot 14 for passing through the anchor 8 of the holder 7. Furthermore, in the exemplary embodiment shown, an (optional) insertion opening 13 is provided, which is wide is enough to allow the head of a holder to pass, so that the holder 7 can be received via the insertion opening 13 in the insertion channel 10, and the anchor 8 in the connecting slot. In the exemplary embodiment of Figure 2A the tile 3 is attached to two holders 7. The insertion opening 13 can be prefabricated during the manufacture of the tile, but can also be arranged later, for example by drilling, at the construction site during the erection of the refractory lining.
    Figures 1A and 2A show how tile 3 'is slid onto two holders 7 and placed on a tile 3 located below. Jointing material (not shown) can be applied and / or glued between the tiles such as horizontal jointing material between the underside of the upper tile 3 'and the upper side of the lower tile 3. Vertical jointing material (not shown) can also be provided between the adjacent vertical side walls of the tiles.
    In Figure 1B the free space 11 is shown between the tiles 3 and the pipe wall 2, which is filled with a hardening molding compound. This casting mass should preferably be present everywhere between the metal parts - pipe wall and holders - and the refractory bricks to prevent the corrosive flue gases in the incinerator from coming into contact with the metal parts during use. To make the heat transmission through the refractory lining as high as possible, the thickness of the free space and of the cured casting mass must be as small as possible. However, a too thin free space between the tiles and the pipe wall will influence the pouring process pouring process, so that inhomogeneities will arise in the cured casting layer, possibly creating zones in the free space where no casting layer is present. This greatly increases the risk of damage to the pipe wall by the corrosive flue gases.
    Figures 1A-2A furthermore show the (covering) spacers 20 according to the invention. The spacers 20 are arranged between the adjacent side ribs 12 (see Figure 2B) of four refractory tiles 3. By using these spacers 20 it becomes possible to quickly and efficiently align the covering of the tiles 3 horizontally and vertically. These spacers also prevent joint material, such as felt, from being pressed out of the joints between the tiles by the hydrostatic pressure of the casting compound. When there is cast mass in the joints, the tiles can hardly expand or hardly expand and the risk of cracks and / or breaking and falling out of the covering increases. The spacers 20 also prevent tiles from being pressed from the holders by the hydrostatic pressure of the casting compound when simultaneously filling the free space of three or more rows. In Figures 1A-2C, the spacer 20 is provided on its rear side with an optional arm element 30, the arm element 30 being designed as a spacer spring.
    Figures 3A and 3B show an embodiment of a spacer 20 according to the invention in more detail. The spacer 20 comprises a front wall 21, a rear wall 22 and a flat body 23, the flat body 23 extending between the front wall 21 and the rear wall 22. The front wall 21 is provided with a first clamping edge 24 formed by the flanged horizontal top edge 25 of the front wall 21. The front wall 21 is also provided with a second clamping edge 26, formed by the flanged horizontal bottom edge 27 of the front wall. As shown in Figure 3B, the spacer 20 can hereby be clamped on a top side and a side rib 12 of a tile 3, wherein the front wall 21 and the rear wall 22 both extend over the front and rear sides of the tile 3. The flat body 23 is provided on its underside with three parallel ribs 28, whereby the desired and necessary joint height is obtained and also sliding or displacement of the horizontal joint material between the tiles is prevented. The rear wall 23 is provided with a coupling element 29 for an optional arm element 30 so that the distance between the spacer, and therefore also the distance between the tiles and the pipe wall, can be adjusted to the length of the holder, so that the free space 11 between the tiles 3 and the pipe wall can be optimally adjusted.
    Figures 3A - 4B also show an alternative embodiment of the spacer 20, wherein the rear wall 23 is provided with a coupling element 29 for an arm element 30. The coupling element 29 is in particular an elongated groove or is formed by two elongated groove parts, which extend horizontally. In Figures 4A and 4B, the spacer 20 is provided on its rear wall 22 with an arm element 30. As a result, the spacer and the associated side ribs and corner points of the tiles are moved away from the pipe wall by the repelling force exerted by the arm element, whereby the tiles are pressed with their insertion channel against the underside of the head of the holder, so that the tiles are positioned at a distance from the pipe wall, which is determined by the length of the head bolt used. The arm element 30 preferably comprises a resilient element 31, so that unevenness in the pipe wall and / or in the lining can be absorbed, while the insertion channel of the tiles is always held against the underside of the head of the head bolt by the applied spring force. In a special embodiment, the arm element 30 is a spacer spring 32. The spacer spring 32 in Figures 4A and 4B is formed by bending back one side 33 of a closed piece of metal wire to the side connected to the coupling element 29 of the spacer 20. Known alternatives to spring elements such as a coil spring or a plate or leaf spring can also be used if desired.
    In Figures 2A and 2C it is shown that the top and bottom of the tile 3 are kept at a uniform distance from the connecting strip 5 of the pipe wall 1 by the (resilient) arm element 30. Figures 1A and 1B show that the bent back side 33 of the spacer spring 32 engages between two pipes 4 on a connecting strip 5 which is not provided with holders 7. It has been found that in this way a very stable and regular covering is formed, wherein the tiles are fixed to holders in the middle and wherein the tiles are fixed at their corners and side ribs by spacers. The spacers are preferably provided with arm elements 30 or even spacer springs 32, which are supported - including resiliently supported - on connecting strips 5 between the pipes 4. The thickness of the free space can also be optimally and accurately, within narrow margins, by using the spacers can be easily adjusted during mounting of the coating, so that an even, homogeneous, cured casting layer of the desired thickness and heat transmission is obtained. It has further been found that refractory lining assembled in this way can be built up faster and more easily and moreover has a longer service life and service life and leads to damage or leakage of the pipe wall less quickly than the known lining.
    The spacers are preferably made of a plastic material such as polyethylene, polypropylene. The spacers are therefore so-called lost material, because the plastic used already burns at low temperatures during the use of the oven.
    Figures 5A - 5C show a special embodiment of the holder 7, designed as a one-piece head bolt. The head bolt is provided with a head 9 with flattened sides 40 and top 43; furthermore, the head is provided with rounded undersides 42 and with a tapered neck section 41 between the head and the smooth anchor 8. The rounded round shape of the underside of the head provides a larger contact surface with the round inner side of the insert channel (also called tile channel) called) of the tile relative to the known flat nuts, thereby preventing notch effect due to line / point contact of the flat head or nut with the inside of the plug-in channel during (hydrostatic) loading during assembly or due to deformation of the tiles During business.
    The tapered neck section 41 makes it easier to assemble the tiles because there is more freedom in the horizontal direction when - in the vertical direction - sliding the insertion channel 10 and the connecting slot 14 onto the holders 7 of the tiles. A smooth anchor 8 has the advantage that it has a 40% higher strength than a threaded rod of the same diameter; in addition, a smooth anchor is more resistant to chemical attack due to the smaller specific surface. Maintaining the surface of the cross-sections of the neck section and the anchor substantially the same produces a bolt on which a tile can easily be placed, but which has no weakened parts or sections.
    Figure 6 shows an alternative embodiment of the refractory lining 1 for a pipe wall 2 of an incinerator according to the invention. In this exemplary embodiment, the refractory lining 1 is provided with a wedge element 50 which is slid into the insertion channel 10 of the tile 3 from top to bottom after the tile 3 with its insertion channel 10 and its connecting slot 14 has been slid onto the holder 7. In this exemplary embodiment, the holder 7 is a one-piece head bolt with a head 9 with flattened sides 40 and top 43, as described above and shown in Figures 5A - 5C.
    By inserting the tapered wedge part 51 of the wedge element 50 into the space 56 (see Figure 1B) between the top 43 of the holder 7 (head bolt) and the inside of the insert channel 10, the (rounded) bottom sides 42 of the holder 7 is pressed against the round inner side of the insertion channel 10, so that the tiles are optimally positioned at the desired distance from the pipe wall 2.
    A preferred embodiment of the wedge element 50 is shown in more detail in Figures 7A - 7B. The wedge element 50 comprises a channel body 52 which is adapted to be received and to be moved in the insertion channel of the tiles. The front side of the wedge element 50 is formed by a front surface 55 which extends over the entire channel body, including the wedge part 51. At the rear side of the channel body 52, a slot body 53 is provided, which is adapted to extend, and in order to be able to move through the narrow connecting slot 14 of the tiles 3. The lower part of the channel body 52 forms the wedge part 51. This wedge part 51 comprises an obliquely sloping surface 54 which, from above, approximately from the surroundings of slot body 53 tapered towards the underside of the front face 55. Due to the above features, the wedge element 50 is always correctly inserted (except when it is inserted upside down) into the insertion channel and the wedge part 51 is easily inserted into the space 56 between the head 9 of the head bolt and the inside of the insert channel 10.
    The wedge element is preferably made of a heat-resistant material such as a ceramic material that corresponds in composition to the casting mass. Known compositions are used for the ceramic material, including compositions with 60% SiC concrete.
    Figure 8A shows an alternative embodiment of the refractory lining 1 for a pipe wall of an incinerator according to the invention. In this exemplary embodiment, the refractory lining 1 is provided with a repair tile 3 '. The repair tile 3 'is provided with an insertion opening 13, preferably in the insertion channel 10. This tile 3' is used when a new piece of cladding must connect to an existing part or when a tile has to be replaced. Because the tile can now not be slid from top to bottom with its insertion channel 10 on the holders 7, the repair tile 3 'is provided in the insertion opening 13 on the (tile) by means of a clip or click element 60 ) holder 7 attached. In the exemplary embodiment of Figure 8A, the original two tile holders 7 have been removed and a tile holder 7 'has been provided at a new position, at the level of the' prefab 'insert opening 13 of the tile, on a connecting strip 5 of the pipe wall 2 (see Figure 8B). - 8C). If desired, the insertion openings 13 can also be provided on site in the tile during construction of the refractory lining, for example by drilling.
    By applying the clip element, the tiles are optimally positioned at the desired (same) distance from the pipe wall, so that a good horizontal and vertical alignment is obtained with the adjacent tiles.
    The repair tile 3 'can be provided with a filling opening in the form of a whole or semicircular filling opening, so that the curing casting mass can easily be introduced into the space between the tile (s) and the pipe wall.
    Figures 8B - 8C show how the tile 3 'is clicked onto the tile holder 7' with the aid of the clip element 60 in the insertion opening 13. By inserting the tile holder 7 'into the clip element 60, the clip is element locked in the insertion channel 10 in that the distance between the hook lips 68 of the clip wings 62 is greater than the width of the connecting slot 14 of the tile 3, 3 '.
    In figures 9A - 9C, the application of the repair tile 3 'is shown in detail in isometric views. In Figure 9A, the V-shaped clip element 60 is inserted through the connecting slot 14 into the insertion channel 10 and into the insertion opening 13. In Figure 9B, the clip element 60 is in the insertion channel 10 of the repair tile 3 ', the support lips 66 being in the insertion opening 13 and the hook lips 68 (not visible) being located behind the connecting slot 14. The tile holder 7 'in Figure 9B is provided with insert parts 44 such as a head 9 of the head bolt of Figures 5A-5C. The insert parts 44 are received in the openings 70 in the clip wings, as a result of which the clip wings and the hook lips can no longer move towards each other and the clip element is fixedly locked in the insert channel 10. The insert parts 44 of the head bolt holder 7 'are locked in the openings 70 of the clip element so that the tile 3' is locked in place on the holder 7 '.
    In Figures 10A and 10B, a clip element 60 according to the invention is shown enlarged, 10A is a top view and 10B is an isometric view. The clip element 60 comprises two clip wings 62 which are connected to each other on their base side 63. In this exemplary embodiment, the clip wings 62 can be folded relative to each other into a V-shaped element about the base or folding line 63. The clip wings are provided on their upper sides 64 with a support lip 66 and with a hook lip 68. The two clip wings 61, 62 are provided with openings 70 for receiving, clamping and locking the insert parts 44 of a (tile) holder 7, 7 '. The openings 70 of the clip wings are provided in this exemplary embodiment with engaging means 72 for the insert parts 44 of the holder. In this exemplary embodiment, the engaging means 72 are formed as a serrated edge with teeth on the top of the opening 70 for additional tolerance and grip, so that displacement or displacement of the insert parts 44 of the tile holder 7 is limited.
    In Figs. 10C - 10E, two isometric views (10C - 10E) and a side view (10D) show the snapping of the tile holder in detail. In this exemplary embodiment, the tile holder 7 is the head bolt of Figures 5A - 5C with rounded undersides 42 and with a tapered neck section 41 between the head 9 and the smooth anchor 8. When the clip element 60 clicks into place on the tile holder 7, support lips 66 in contact with the insert parts 44 of the head 9 of the holder 7. The head 9 thereby forces the support lips 66 and thus the clip wings 62 further apart, so that the hook lips 68 leave the zone of the connecting slot 14 are moved, whereby the hook lips hook the clip element 60 into the insertion channel 10 of the tile 3. When the insert parts 44 of the head 9 of the holder 7 are the support lips 66 of the clip element 60 passed, the insertion parts 44 fall into the openings 70 arranged in the clip wings 62 and are thereby snapped into the clip element 60 (Figures 10D - 10E). In Figures 10D - 10E it is shown that the insert parts 44 protrude through the openings 70 in the clip wings and are therefore inseparably connected to the V-shaped clip element 60.
    The (flipped, flat) clip element preferably has a dimension of approximately 50 x 45 mm with a thickness of approximately 0.8 mm and is preferably made of a heat-resistant metal including stainless steel (AIST 309/310).
