    Spacer for a block-shaped stone and a method for covering a substrate with block-shaped stones
    The invention relates to a spacer for a block-shaped brick of which at least one side is to be positioned at a predetermined distance from one side of a second block-shaped brick.
    Such a spacer holder is known per se and serves to facilitate positioning of stones such that a joint groove is created between the stones and, preferably, is also retained thereafter.
    Such spacers are generally finger-shaped or rib-shaped, so that the spacer occupies space only over a length, and sometimes also a limited depth, of the joint groove. Sufficient space then remains in the joint groove for joint material, which usually consists of sand for laying bricks for covering a substrate.
    It is possible that the stone is already provided with such a spacer during its manufacture. In that case the spacer is then often an integral part of the stone and made of the same material from which the rest of the stone is made. This has the drawback that the mold in which the stone is formed is complicated and therefore relatively expensive and that wear of the mold also has an undesirable influence on the dimensional accuracy of the spacer.
    With a view to cost savings and environmental considerations, there is a clear trend in which already used stones are reused for the same purpose. This is particularly the case with re-pavements. In the Netherlands, reuse of covering bricks is also attractive for the necessary dike elevations. For this purpose, covering stones must be removed from the dike, and after raising the dike, covering stones must be placed again. The commissioning of new fractured bricks could involve a lot of heavy goods traffic coming and going, which is preferably minimized in areas where the environment can be susceptible to such a disturbance. From that point of view, the reuse of stones could be preferred. However, for a very large part of the stones that were previously used to cover the dike, it holds that no spacer is integrally fitted. Here, a replacement of the stones with the expected costs and disadvantages for the environment seems possible only if a solution can be found for the absence of spacers.
    German patent specification DD 296 723 A5 describes spacers that can be attached to the stone by means of adhesion. This could possibly take place with stones already in use. The application, however, seems a very cumbersome process. In the case of adhesion, it further holds that the surfaces to be glued must be cleaned, which may still be feasible for new bricks, but is very difficult or impossible to perform with bricks that have already been used.
    It has also been considered to place the spacers on the relevant surface before the stones are placed (back). This appears not to work, since under the weight of the relatively heavy stones, the spacers are quickly moved and / or broken when the stones are laid.
    It is an object of the invention to provide a spacer that addresses at least one of the disadvantages mentioned above.
    This object has been achieved with a spacer as described in claim 1. This relates to a spacer for a first block-shaped brick of which at least one side is to be positioned at a predetermined distance from one side of a second block-shaped brick. According to the invention, the spacer is provided with a buffer body and furthermore designed such that the spacer can be clamped around the first brick and thereby provides that one side of the first brick with the buffer body for creating the predetermined distance.
    This offers the advantage that the stone in question does not have to be made very clean. The spacer could be arranged mechanically, and in any case before the brick is placed (back). The stone and the spacer clamped to it are placed as a whole so that displacement of the spacer and / or breaking of the spacer will hardly or never occur.
    In an embodiment of a spacer according to the invention, the spacer is provided with a connecting element and at least two clamping bodies connected to each other by said connecting element which are oriented such that each clamping body can clamp against a side of the brick so that two opposite sides of the first brick has each clamped one of the clamping bodies against itself. This offers the advantage that at most three sides of the block-shaped brick must be provided with a part of the spacer, namely two sides which are provided with a clamping body and a side along which the connecting element extends. This again offers the advantage that the other sides of the brick can be free to manipulate the brick without running the risk of damaging, shifting or removing the spacer from the brick.
    In an embodiment of a spacer according to the invention, the connecting element lies in an imaginary plane that can correspond to a plane that lies against the underside of the first brick. This offers the advantage that the connecting element is not visible in use and cannot easily be removed by, for example, rinsing water.
    In an embodiment of a spacer according to the invention, each buffer body is oriented as a post relative to the connecting element. As a result, stone joint material laid with the aid of the spacer can be efficiently added to the formed joint. Incidentally, water supply (rainwater, rinsing water) and water drainage (evaporation) or to the substrate and from the substrate can also take place relatively unhindered and the flow pattern is not or hardly influenced by the presence of the buffer body.
    In an embodiment of a spacer according to the invention, each clamping body is oriented as a post relative to the connecting element. The advantages described above for a buffer body designed as a stand also apply here.
    In an embodiment of a spacer according to the invention, each buffer body comprises one of the clamping bodies. This offers the advantage that the spacer is very easy to implement and very easy to apply. The spacer takes up a minimum of space and also requires a minimum of material costs.
    In an embodiment of a spacer according to the invention, the connecting element is designed such that the distance between the clamping bodies in a non-clamping state of the spacer is smaller than that distance in a clamping state of the spacer. This has the advantage that with this spacer the clamping is achieved when the distance between the clamping bodies from the non-clamping state is increased, which means that the spacer is designed to be self-clamping. If clamping were to occur with a reduction of the distance between the clamping bodies from the non-clamping state, this would mean that an active action would have to be carried out for the purpose of clamping, which complicates applicability.
    In an embodiment of a spacer according to the invention, the connecting element comprises at least one arc, such that a radius of the arc in the clamping state is greater than the radius of that arc in the non-clamping state. This means that the construction of the connecting element can be very simple and the material properties of the spacer can possibly be homogeneous. The tolerance in the dimensions of the block-shaped brick for retaining the applicability of a given spacer can also be easily determined.
    For an embodiment of a spacer according to the invention, it holds that the spacer is provided with at least two spatially separated abutments. This increases the efficiency of the spacer.
    For an embodiment of a spacer according to the invention, it can hold that of the at least two spatially separated abutments, two abutments are positioned such that when the spacer is used, both sides of two opposite sides of the first brick are each provided with an abutment body . This means that those two sides are possibly interchangeable, which increases the possibilities for manipulating a used brick. For example, an already slightly worn side can be positioned in such a way that further wear is not expected to occur, or hardly so.
    For an embodiment of a spacer according to the invention, it can furthermore apply that of the at least two spatially separated abutments, two abutments are positioned such that, when the spacer is used, one side of the first brick is provided with these two abutments. As a result, in use, the joint between the relevant sides of two bricks placed next to each other will have a width that is imposed by the dimensions of the two abutments. When only one butt body is placed in the joint, it is possible that the widths of the joint on both sides of the butt body undesirably differ relatively greatly from one another.
    For an embodiment of a spacer according to the invention, it can also apply that the abutments are positioned such that in a situation where a side of the first brick is provided with the spacer and a side facing that side of the first brick is provided with a second brick of the spacer, the predetermined distance can be taken by abutments from both the spacer from the first brick and from the spacer from the second brick. This may entail that the abutments of the stones placed next to each other also obtain a mutual positioning in a longitudinal direction of the joint, for the convenience of laying the stones, and possibly maintaining those positions of the stones with forces which without such positioning, it would rather lead to mutual shift of the bricks.
    The invention also relates to a method for positioning a plurality of stones relative to each other for covering a substrate, wherein each stone is provided with a spacer according to one of the embodiments discussed above.
    A special embodiment of a method according to the invention is characterized in that the stones are simultaneously provided with the spacer, wherein each spacer is included in a predetermined pattern prior to placing around the relevant stone, corresponding to a predetermined pattern in which the stones be laid. This allows a very efficient method.
    The invention will now be explained with reference to a drawing. It shows:
    Figure 1 shows diagrammatically in a transparent perspective a first embodiment of a spacer according to the invention;
    Figure 2 shows diagrammatically in a transparent perspective a second embodiment of a spacer according to the invention;
    Figure 3 shows diagrammatically in a transparent perspective a third embodiment of a spacer according to the invention;
    Figure 4 schematically shows a top view of a plurality of stones laid according to an embodiment of a method according to the invention;
    Figure 5 schematically shows a top view of a plurality of stones laid according to an embodiment of a method according to the invention; and
    Figure 6 schematically shows a top view of a fourth embodiment of a spacer according to the invention.
    In the figures and the description, the same elements are provided with the same reference marks.
    Figure 1 shows a block-shaped brick 1 and a first embodiment of a spacer 2 according to the invention. The spacer 2 is useful when a side 3 of the brick 1 is to be positioned at a predetermined distance D from a side 3 'of a second block-shaped brick 1'. Figures 4 and 5 schematically show a top view of such a mutual positioning of these stones 1, 1 '. The spacer 2 is provided with an abutment body 4 and is furthermore designed in such a way that the spacer 2 can be clamped around the brick 1. Thereby, the spacer 2 provides that one side 3 of the brick 1 of the buffer body 4 for creating the predetermined distance D.
    In the embodiment shown, the spacer is provided with a connecting element 5 and at least two clamping bodies 6, 6 'connected to each other by said connecting element 5, which are oriented such that each clamping body 6, 6' can clamp against a side Z of the brick 1 so that two opposite sides Z of the first brick 1 each have one of the clamping bodies 6, 6 'clamped against it. As can be seen in Figure 1, the buffer body 4 preferably also functions as a clamping body 6. It could be said that the buffer body 4 in that case comprises the clamping body 6.
    The spacer 2 is shown as included in use. It can clearly be seen that the connecting element 5 according to this example lies in an imaginary plane that can correspond to a plane that lies against the underside of the brick 1.
    The buffer body 4 is preferably oriented as a post relative to the connecting element 5. Also, each clamping body 6,6 'is preferably oriented as a post with respect to the connecting element.
    In both Figure 1 and Figure 2, a spacer 2 'in a non-clamping state is also drawn with the aid of a thick broken line.
    As can be seen from these figures, the connecting element 5 is designed such that the distance A 'between the clamping bodies 6, 6' in a non-clamping state of the spacer 2 'smaller than that distance A in a clamping state of the spacer 2 To keep the figures 1 and 2 clear, the distances A and A 'are shown for simplicity as projected against a short side of the stone. For the sake of convenience, the contribution of the displacement of the spacer in the direction of the longest side of the stone is not included in the distance determination. In reality, of course, this shift ensures that the distance A between the clamping bodies 6,6 'is longer than represented by the relevant line A'. Such a spacer 2 'is thus arranged to increase the brick by the distance A' between the clamping bodies 6,6 'from the non-clamping state to distance A and then to place it as shown by spacer 2. The tendency (shown schematically by arrow V) of the spacer 2 to assume a position as shown by spacer 2 'ensures that the clamping bodies 6, 6' press against the relevant side of the brick. The spacer is then in the clamping state. It could be argued that the connecting element can be moved from the non-clamping state to the clamping state against a spring force and that the clamping force is caused by that spring force.
    In this exemplary embodiment, the connecting element 5 comprises at least one arc, such that a radius of the arc in the clamping state is greater than the radius of that arc in the non-clamping state.
    As shown in Figure 1, the clamping body 6 ', can be plate-shaped. In fact, any shape is suitable as long as it permits the function of the clamp body and does not interfere with the function of the spacer. It is not inconceivable that the spacer has two clamping bodies 6,6 'and a spacer thereof, but also as a part of the spacer. The clamping body cannot be thicker than the buffer body, so that the clamping body does not interfere with the functioning of the buffer body. It is, however, possible that each buffer body also functions as a clamping body, and vice versa. Each buffer body can therefore comprise a clamping body. This is the case in Figures 2-6.
    As shown in Figure 2, the spacer may be provided with at least two spatially spaced abutments 4. In this case, they are positioned such that when using the spacer 2 both sides of two opposite sides of the brick 1 are each be provided with a buffer body 4. The spacer as shown in figure 2 further functions analogously to the spacer as shown in figure 1.
    Figure 3 shows an embodiment of a spacer according to the invention in which two spacers are spaced apart from one another and two spacers are positioned such that, when the spacer is used, one side of the first brick is provided with these two spacers. In this example, the spacer 2 has four abutments 4, the connecting element of the spacer 2 is X-shaped, each leg of the X being arcuate. The intersection of the X is shifted with respect to the geometric center of the spacer 2. The positions of the abutments 4 on one side 3A of the brick 1 is different from the positions of the abutments 4 on the opposite side 3B of the stone 1.
    Figures 4 and 5 show in a schematic top view that the abutments 4 can be positioned such that in a situation where a side 3 of the first brick 1 is provided with a spacer 2 as shown in Figure 3 and a side 3 of the side 3 'of second stone 1' facing first stone 1 is provided with a spacer 2 as shown in figure 3. The predetermined distance D can be occupied by abutments 4 of both the spacer 2 of the first stone 1 and of the spacer 2 from the second stone 1 '.
    These figures 4,5 also show the joint groove 7 formed with the aid of the abutments. In figure 4 the stones 1,1 ', 1' are staggered in the longitudinal direction of the joint groove 7 with respect to each other. In figure 5, the stones 1, 1 'lie next to each other over the entire length of the stones. joint groove shown along a shortest side of the bricks This method of arranging the bricks Ι, Ι ', Ι' 'is suitable for covering a dyke with the bricks, such that the joint groove 7 extends in the longitudinal direction of the embankment The joint groove 7 is then in the longitudinal direction In contrast to a joint groove 7 oriented transversely to the longitudinal direction of the dike, joint material such as, for example, sand is not flushed by water (e.g. rain water or sea water) from a joint groove oriented in the longitudinal direction .
    A method of positioning stones relative to each other for covering a substrate can be very well carried out when each stone Ι, Ι ', Ι' 'is provided with a spacer 2 according to the invention. Re-paving with the original stones (which are generally not provided with a spacer) also leads to a good result with the aid of the spacer according to the invention.
    Incidentally, it is also quite possible to mechanically carry out such a method of re-paving. For example, a "package" of bricks can be picked up simultaneously with the aid of a per se known manner. Each brick is herein taken up with, for example, a suction cup. The suction cup then sucks itself onto the top of the brick. The suction cups are thereby arranged in the same way as the stones were arranged for receiving. Then the stones 1,1 ', 1' are simultaneously provided with the spacer 2. For this purpose, for example, each spacer 2 can be included in a predetermined pattern prior to placing around the relevant brick 1,1 ', 1' ' with a predetermined pattern in which the stones 1, 1 ', 1' 'are placed. The spacers 2 can, for example, each adhere to a sheet with an underside of the connecting element 5. The sheet and the stones Ι, Ι ', Ι "can be manipulated relative to each other in such a way that each stone is 1.1', 1 '' provided with a spacer 2. The sheet can then be taken off and the package of stones can be removed be laid in one step.
    The examples shown in Figs. 1-5 could give the impression that a spacer according to the invention can only provide two sides of a stone with one or more abutments 4. However, the spacer according to the invention can also be designed such that each side of a stone 1 is provided with an impact body. An example is shown in Figure 6. The arrows V show the direction in which the legs of the connecting element 5 would move under spring force when the spacer 2 was removed from the brick 1 and then assumed the non-clamping state from the clamping state.
    As previously indicated, it is possible that the clamping bodies 6, 6 and the abutment bodies 4 are separate bodies. Here, each butt body 4 will often be connected to a clamping body 6, 6 '. An advantage of such an embodiment is that each body can be focused on the function in the spacer 2. The buffer body 4 is, for example, preferably circularly cylindrical so that regardless of the extent to which the connecting element 5 is stretched and thereby determines the position and orientation of the buffer body 4 , the predetermined distance between the stones will always be the same. Such a buffer body 4 is perhaps less suitable for performing a clamping function. A clamping body 6, 6 'is perhaps better designed in the form of a plate, as is shown, for example, in Figure 1. The aim here is a relatively large surface with which clamping takes place. It is also possible that one or more impact members 4 are of slightly conical design. This can facilitate arranging spacer 2 around the brick. The base of the cone then imposes the predetermined distance with respect to an adjacent brick. Such conical abutments 4 are also suitable for substrates that are somewhat spherical or, on the contrary, concave.
    The conically shaped bumpers 4, which also function as clamping bodies 6,6 ', can also have different longitudinal shape, in order to optimally perform the various functions.
    A spacer 2 according to the invention can easily be manufactured as a whole. A spacer 2 according to the invention can be made from a thermoplastic plastic and / or from a rubber, for example by means of injection molding.
    The invention is not limited to the embodiments shown and to the embodiments discussed above. Many variants are possible.
    In particular, it is possible that the spacer is suitable for block-shaped stones, which for instance have a hexagonal upper and lower surface. It is also possible that a top of the buffer body is such that, in the non-clamping state, the top can already be slid along the side against which the relevant buffer body must press. When the distance between the connecting element and the lower surface of the stone is reduced, the spacer will then assume the clamping position against the spring force. This is well applicable with a conically shaped buffer body and with a stone where the tolerances in the dimensions are approximately as great as the width of the predetermined distance to be formed, or the width of the joint groove. It is also possible that the standing body does not extend over the entire height of the stone.
    These variants are each understood to fall within the framework of the invention as defined by the appended claims.
