    PREPARATION METHOD PREFABRICATED ELEMENTS
    TECHNICAL FIELD OF THE INVENTION The invention relates to a preparation method for obtaining prefabricated building elements, in particular prefabricated facade cladding elements, preferably built up from bricks, and is characterized in that the vertical building elements to be placed on site are laid flat. composed during production. To this end, the layers of building bricks are placed sideways on a base plate, which, however, is not part of the assembled prefabricated building element but is reused in production.
    BACKGROUND OF THE INVENTION It is known to cover building facades with a facing brick. This is done by placing the individual facing bricks on top of each other in a masonry bond, brick by brick and layer after layer with mortar.
    This is a time-consuming manual work that requires several years of experience to obtain a nice, even masonry. The current application aims to simplify this task through industrial prefabrication.
    In existing prefabrication of masonry for facade cladding, however, standard building bricks are rarely used, but typically a stable, rectangular support plate is covered with a veneer layer of stone strips that are glued to the support plate.
    In the current systems, wall parts are also prefabricated that are made on a flat horizontal table where the bricks are placed face down and where space is formed for ribbon and butt joints by placing spacers between these bricks that increase the thickness. having a joint filling. When this work is finished, a liquid mortar emulsion is usually poured on top of the formed panel to fill the ribbon and butt joints along the back of the prefab panel. A thickness of mortar emulsion is also poured over the entire back of the stones to create a firm “back”. Once this work has been done, the prefabricated plate formed can be turned over after drying and the spacers can be removed, leaving a joint space for the ribbon and butt joints to be joined.
    Instead of working with a horizontal horizontal table, it is more common to work with an upright container in which the building layers are stacked, whether or not provided with manipulable side walls and pressure elements to check the dimensions of the prefab building elements. Such systems are described, for example, in DE 229 14 535, AT 11 361, EP 0924 359, and DE 44 37 858. Since standard building materials are not used, these elements always remain recognizable as such and the appearance and appearance are not obtained. quality of a standard manually executed masonry. Moreover, such panels do not allow customization and must be combined with standard masonry, which does not benefit the general appearance. There is therefore a need for a method that allows prefab building elements to be realized using standard building blocks, and which, provided automation, allows customization to be delivered.
    SUMMARY OF THE INVENTION The present invention relates to a method for preparing a prefabricated building element composed of at least two layers of building blocks. As already indicated above, the method according to the invention is characterized in that the vertically used prefab building elements to be placed on the site are assembled horizontally during production. This means that the building blocks from which the building element is constructed must be placed on their side during assembly. To this end, the present invention uses a base plate on which the layers of building bricks are placed sideways (on their side), and which, after assembling the prefab building element, does not form part of the prefab building element.
    Thus, in a first respect, the present application relates to a method for preparing a precast building element composed of at least two layers of building blocks comprising; - the use of a bottom plate on which the layers of building bricks are placed sideways, so that the bottom plate does not form part of the prefab building element after the assembly of the prefab building element. This implies that the layers of building blocks are not adhered to the bottom plate. The assembled prefabricated building element will thus be removed from the bottom plate after preparation, and the bottom plate will preferably be reusable in the method according to the invention.
    Within the context of the present invention, the building blocks correspond to the standard basic building materials from which a wall can be made or derivatives thereof.
    They are typically beam-shaped elements, made of brick, stone, concrete, wood, plastic, metal and any other material from which a wall can be made.
    When constructing a wall, such building blocks are typically laid in a so-called masonry bond.
    In order to better describe the description of such a connection from which a prefab building element is constructed according to the current invention, we can use the names of the sides of the building blocks as used in architecture and symbolized in Figure 1. Depending on the material from which the building elements have been manufactured, there will be a certain size spread on the dimensions of the building elements, whereby a dimensional tolerance is always specified by the manufacturers.
    The latter mainly occurs with brick building elements with a spread of up to 9mm in the brick length or stretch.
    However, since it is important for the prefab building elements to arrive at a layer size and a head size with a controlled spread, it may be necessary to calibrate the building blocks in advance.
    The calibration means that the construction element is cut to size in one or more directions, eg by milling or sawing the construction elements.
    In one embodiment according to the invention, the building blocks are calibrated on at least one side or side.
    Preferably selected from the flat, straight or end sides of the building block.
    In particular on at least one of the flat sides of the building block; more in particular on one flat side and one short side of the building block.
    Calibrating the building blocks on one of the flat sides not only contributes to checking the spread in the layer size, it also ensures that the assembled building element can be provided with a smooth top and bottom, resulting in a stable and dimensionally stable structure. of the building elements.
    In a preferred form of the method according to the present invention, the building block is calibrated on at least one side, more in particular on one of the flat sides of the building block, and this calibrated side is vertical when the building blocks are placed on the bottom plate sideways. oriented in front of the bottom plate.
    In this way it is obtained that also in this preferred form the visible side of the building blocks is directed upwards, a characteristic characteristic of the method according to the invention.
    As already indicated above, the calibration of at least one of the flat sides of the building blocks ensures that the top and bottom sides of the assembled building element are leveled. Therefore, in an embodiment of the method according to the invention, when building the multilayer building element, the calibrated side of the building blocks of the first layer will face away from the calibrated side of the building blocks of the further layers of the prefab building element. Thus, the calibrated side of the first layer forms the bottom and top side of the composite building element, respectively, and the calibrated side of the extreme further layer forms the respective top / bottom side of the composite building element.
    In the method according to the present invention, the building blocks which are placed on a bottom plate are connected to each other by means of the upright and opposite sides by a connecting means such as an adhesive, silicone, mortar or the like. To achieve the connection, the layers of building blocks must be pressed against each other. The pressing of the building blocks can be done in various ways and any obvious method for pressing the layers while the building blocks are situated on a bottom plate are within the scope of this application. For instance, in the method according to the invention, at least the first layer can be temporarily fixed on the bottom plate during the connection and the further layer (s) can be pressed against the temporarily fixed layer in a horizontal movement in front of the bottom plate. In another example, not the first layer is temporarily fixed on the bottom plate, but the penultimate layer and the last placed layer is pressed against the temporarily fixed layer in a horizontal movement in front of the bottom plate. In yet another example, both the first and the penultimate layer are temporarily fixed on the bottom plate and the last placed layer is pressed against the temporarily fixed layers in a horizontal movement in front of the bottom plate.
    When applying the connecting agent it has been found that the adhesive, silicone, mortar or the like is best applied at the bottom in the contact angle between the building block and the bottom plate. By arranging the connecting means in this position, the bottom plate helps to ensure that the connecting means
    > BE2019 / 5086 will move upwards when pressed and distribute evenly between the building blocks. This prevents connecting means from ending up between the bottom plate and the building blocks, which would otherwise make it more difficult to remove the assembled prefabricated building element from the bottom plate. Thus, in one embodiment of the method according to the invention, the layers of building blocks which are placed on a bottom plate are joined to each other by means of the upright and opposite sides by a connecting means such as an adhesive, silicone, mortar or the like, whereby the connecting means becomes applied in the contact angle between the building block and the bottom plate.
    Preventing connecting means from ending up between the building blocks and the bottom plate can further follow from the temporary fixation of the layers on the bottom plate against which the last placed layer is pressed. If these layers are pressed against the bottom plate during temporary fixation, this will also contribute to preventing connecting means from ending up between the building blocks and the bottom plate. Thus, in a preferred form, the penultimate layer is pressed against the bottom plate during temporary fixation and the connecting means is applied in the contact angle of the free adjacent side of this penultimate layer and the bottom plate, the last placed layer then in a horizontal movement opposite. of the bottom plate is pressed against the temporarily fixed layer. In addition to pressing against the bottom plate, the texture of the building block can also contribute to preventing connecting means from ending up between the building blocks and the bottom plate. For smooth building blocks such as glue blocks, there is good contact between the building block and the bottom plate over the entire surface, so that there is no free space between the contact surface of the building block and the bottom plate when pressing. For building blocks with a rougher surface such as bricks, there may be free spaces between the contact surface of the building block with the bottom plate, which spaces are accessible to the connecting means when the connecting means are applied and / or the layers are pressed horizontally, with the result that connecting means gets between the building blocks and the bottom plate, which could make it more difficult to remove the assembled prefabricated building element from the bottom plate. In order to offer a solution to this, in an embodiment according to the invention, the side facing with which the building block is placed on the bottom plate can be leveled, for example milled or sawn. In a preferred form, the building blocks are sawn in two in the direction of stretching and the obtained klisklezoren are placed with the sawn side on the bottom plate. Sawing the building blocks into klisklezoren also means that the thickness of the building element is halved, so that the assembled prefab building element becomes lighter and therefore easier to manipulate.
    As further described herein by way of an example assembly line, the method of the invention can be automated. Regardless of whether the method is carried out in an automated manner or in a manual manner, in the method as described herein the prefab building element is built up layer by layer. How the building blocks are oriented in relation to each other in building the layers is in principle free, as far as the building blocks are placed on the side and in the event that one of the sides is leveled, they are placed with this side on the bottom plate. Thus, the calibrated sides of the building blocks for each of the layers can either face each other or face away from each other. In a preferred form, the calibrated sides of the outer layers will be directed outwards, thus obtaining a smooth (flat) top and bottom side of the composite building element. In the intermediate layers of such a composite building element, the calibrated sides of the building blocks may face each other or face away from each other.
    In a possible embodiment of the method according to the invention, the method comprises the following steps: - a first layer of calibrated building blocks is placed sideways on the bottom plate, whereby the orientation of the calibrated side forms the bottom side of the prefab building element (Fig. 9 A ); - this first layer is provided with a connecting means on the opposite side of the underside of the prefab building element (Fig. 9 B); preferably in the contact angle between the building blocks and the bottom plate; - a second layer of calibrated building blocks are placed sideways on the bottom plate, opposite the first layer, with the calibrated side facing the bottom or away from the bottom of the prefab building element (Fig. 9 C); preferably faces away from the underside of the prefab building element; - the first layer is temporarily fixed on the bottom plate (not shown in Fig. 9); preferably comprising pressing the first layer onto the bottom plate; - the second layer by horizontal movement in front of the bottom plate
    I: BE2019 / 5086 are pressed against the temporarily fixed layer (Fig. 9 D).
    In the previous method it is now apparently included that the first layer is only temporarily fixed on the bottom plate prior to the pressing of the second layer, but after the application of the connecting means. It is important to note that the method includes temporary fixation of the first layer regardless of when, except that it must always be prior to pressing of the second layer. In a preferred form, the first layer will also be temporarily fixed on the bottom plate prior to the application of the connecting means. It will be clear to those skilled in the art that for building up a building element from several layers the foregoing method will be repeated until the total number of layers from which the building element is built up has been reached. Thus, in a further embodiment, the preceding method comprises the additional steps that: - the previous (second) layer is provided with a connecting means on the opposite side of the underside of the prefabricated building element (Fig. 9 E); preferably in the contact angle between the building blocks and the bottom plate; - a next layer of calibrated building blocks are placed on the bottom plate, opposite the previous (second) layer with the calibrated side facing the bottom or away from the bottom of the prefab building element (Fig. 9 F); preferably faces away from the underside of the prefab building element; - the first and / or previous (second) layer is temporarily fixed on the bottom plate (not shown in Fig. 9); preferably comprising pressing this first and / or previous (second) layer onto the bottom plate; - the next layer is pressed against the temporarily fixed layer by means of horizontal movement in front of the bottom plate (Fig. 9 G); and this process is repeated until the prefab building element has been built up from the number of desired layers (Fig. 9 H). In a preferred form of the foregoing method, the calibrated side of the last layer will face away from the underside of the prefab building element. In the previous method it is now seemingly included that the previous (second) layer is only temporarily fixed on the bottom plate prior to the pressing of the next layer, but after the application of the bonding agent. It is important to note that the method involves the temporary fixation of the previous (second) layer regardless of when, except that it must always be prior to pressing the next layer. In a preferred form, the previous (second) layer will also be temporarily fixed on the bottom plate prior to the application of the connecting means.
    Characteristic of the method according to the invention is that the prefab building element thus composed is allowed to harden on the bottom plate. Curing can be done simply in the ambient air and at the ambient temperature, but can also be done under more controlled conditions, for example in a drying tower at a controlled temperature of, for example, a maximum of 30 ° C, whereby the bottom plates with the prefabricated building element assembled thereon through a transport system through the tower ( s) is moved. Curing may also be promoted by the use of a quick-drying compound.
    As already indicated above, the building blocks are placed in a so-called masonry bond during the manufacture of the building element. Or in other words, when building up the building element in a method according to the invention, the layers are laid in the bonds customary within masonry, such as a stretcher bond, chain bond, English bond, Klezoren bond, cross bond, a koppen or patijts bond, a Flemish bond or a bond. wild bond, in addition to the aforementioned load-bearing bonds, non-load-bearing bonds can also be used in the construction of the building element, such as a tile bond or a block bond. In a preferred form, the construction element is constructed in such a way that the construction elements have toothing on at least one side, which is such that the construction elements fit together laterally with their toothing and can be manipulated and placed by one or two persons or with a technical aid. . Possible teeth that can be realized by means of the method according to the invention are a falling tooth, a block tooth and a standing tooth.
    A building can then be assembled in a simple manner with the building elements thus obtained. The building elements, and in particular those constructed from klisklezoren, are particularly suitable for realizing the outer building envelope of a building, more in particular as facade cladding. But also as hanging ceilings or floor covering. In one embodiment of the invention, the bottom plate used in the
    BE2019 / 5086 method an upright edge, in which a layer of the building blocks are placed against this upright edge. The presence of such an upright edge is useful, for example, in case during assembly the bottom plate is not placed level but at a slight angle as shown for example in Figure 6. Preferably consists of the layer of building bricks which is placed against the upright edge of the bottom plate , from the first layer of building blocks, wherein this first layer of building blocks is preferably laid with the calibrated side against the upright edge. This upright edge contributes to the horizontal fixation of the first layer of building blocks on the bottom plate, and thus provides a stop edge when the layers are pressed against each other by means of a horizontal movement in front of the bottom plate. Again, in a preferred form, and in order to prevent connecting means from ending up between the building blocks and the bottom plate, the first layer is also pressed against the bottom plate during temporary fixation, even in the presence of a raised edge. For pressing these first and / or subsequent layers onto the bottom layer, use can be made of a clamping device such as a pneumatic or manual clamping device, e.g. provided with different pneumatic pressure fingers, which are placed over the layer of building blocks and pressed or pulled in opposition. of the bottom plate so that the layer of building blocks are clamped between these pneumatic pressure fingers and bottom plate. By making use of a clamping device with several pressure points spread over the layer of building blocks, these can be individually pressed. In addition, this ensures that the butt joint remains accessible for the application of connecting means.
    In the method described herein it has already been indicated which measures can be taken to prevent connecting means from getting between the building blocks and the bottom plate, so that subsequent removal (after curing) of the bottom plate can be made more difficult. In addition to placing the connector in the contact angle between the building block and the bottom plate and ensuring that the building block makes contact with the bottom plate with an even flat side, it is also possible to ensure that there is no good adhesion between the bottom plate and connector. To this end, the bottom plate can for instance be provided with an anti-adhesive layer or even a removable foil. Thus, in a further embodiment according to the method of the present invention, the bottom plate will be provided with a foil, anti-stick coating or equivalent. In the following automated embodiment the bottom plate is also provided
    -10- BE2019 / 5086 of a recognition system such as a barcode, QR code or RFID.

    DETAILED DESCRIPTION The following description, in conjunction with the figures, clarifies to those skilled in the art how, by way of example, the method of the invention can be practiced in practice. The method described is a robotic method in which an installation is described which consists of two parts, namely a sawing and milling line and a masonry assembly line. The purpose of the sawing and milling line is to calibrate the building blocks, cut them to size, provide them with a smooth surface, and prepare them for the assembly (masonry-assembly) line. First, the stones are calibrated at height. This is done by means of a stone cutter (Fig. 3).
    Then the whole stones are milled or sawn to length and cut in half in the longitudinal direction. In this way, klisklezoren are obtained that are calibrated for thickness and length. The sawn bricks are turned with the sawn side down and the robot then distributes these bricks over the input paths of the masonry line. Ultimately it is also with this sawn side that the building blocks will be placed on the bottom plate in the mounting unit. Sawing in half thus ensures that the stones have a smooth surface, which has an amount in the method according to the invention in preventing connecting means from ending up between the building blocks and the bottom plate. When distributing the bricks over the input paths of the masonry or assembly line, the robot will also ensure that the calibrated length side and calibrated thickness side for each of the bricks are oriented the same way.
    -12- BE2019 / 5086 Besides the standard shapes; Whole stones, klisklezoren, three quarters, half stones, klezoren, three quarters sawn in half, half stones sawn in half and klisklezoren, the cutting line also allows special shapes such as angles to be sawn at half, three quarters and full length.
    The whole stones (klisklezoren) can also be cut to half and three-quarter length.
    The special shapes are sawn by a 2nd robot in a specially designed saw unit, after which this robot also distributes these bricks over the infeed paths of the masonry line.
    Possible corner stones are placed over the edge of the bottom plate during construction (see Fig. 6), the corner stones can be placed over the long side (Fig. 6 A) as well as over the short side (Fig. 6 B) of the bottom plate laid.
    The sawing units are provided with an appropriate dust extraction (local and with sufficient covering), provided with the necessary pipes and motors to guarantee the local dust extraction.
    The canopies for the dust extraction are constructed in such a way that the sawing process is sufficiently visible for a visual inspection during the operation of the installation.
    A blowing nozzle is also placed in line with the saws to remove any dust from the stones.
    All sawn stones are placed by the robots in the relevant infeed tracks or pick-up line in front of the mounting unit.
    The infeed conveyors or pick-up lines are equipped with the necessary photocells (min / max, presence). The number of stones that enter the pick-up line and the number of stones that are picked up are kept in the plc.
    This means that the plc always knows how many stones are buffered in a pick-up line.
    There must always be a minimum number of stones in the pick-up line.
    These minimum numbers can be set separately for each pick-up line via the screen.
    If fewer stones are buffered than set, a signal is automatically given to the saw unit to replenish these stones.
    A photocell "minimum" is also provided as an extra check.
    If this photocell no longer detects a stone, the installation is shut down and an alarm is generated.
    Even when the infeed tracks are full, no stones are supplied.
    The infeed conveyors are also equipped with the necessary pneumatic cylinders (stoppers). These can be part of a measuring unit in which the length of each stone is measured.
    The measuring unit consists of 4 pneumatic cylinders.
    These cylinders are pressed against the stones, and the length of the stone can be determined very accurately on the basis of the outward stroke of the cylinders.
    -13- BE2019 / 5086 For assembly, the required stones are picked up by a robot with gripper head (Fig. 4) from the infeed tracks and placed in a row with their sawn side on a base plate. When moving the infeed conveyor to the bottom plate (also called mounting plate), the robot first moves the bricks past a measuring unit. The stones are then placed in the correct position during the movement to the mounting plate depending on the measured length of the stone. The stones are deposited on the mounting plate. If the robot has not picked up a stone, this will be detected by the measuring unit because it is receiving an incorrect measurement.
    The installation will then be shut down and an alarm will be given. The gripper head is equipped with 4 servo motors, each of which drives a linear guide for each of the gripper arms. The stones are picked up past each other by the gripping arms and brought to a measuring unit. After the stones have been measured, the stones are moved to the correct position by the servomotors and finally aligned by pneumatic cylinders for each of the gripping arms. As indicated earlier, the stones are placed with the sawn side down in the supply tracks. The gripping robot picks up the stones at the top. Thus the line of bricks will be placed with the sawn side on the mounting plate. Since the orientation of the calibrated sides is the same for each of the stones in the supply tracks and the head of the gripping arm is also capable of performing a rotational movement in the horizontal plane, the gripping robot can also ensure that the first row of stones placed on the mounting plate with the calibrated side upright with respect to the bottom plate and in a first direction (eventually the bottom of the building element) and the following rows with the calibrated side upright with respect to the bottom plate and in an opposite direction whereby the calibrated side of the last layer will eventually make up the top of the building element. With reference to Fig. 8 series A-C, the orientation of the first row of bricks on the bottom plate can still be adjusted by the pressing unit (Fig. 7 & 8) which holds the bricks, when gluing and pressing the layers together. , provides a temporary fixation of the layers on the bottom plate. For this purpose, the pressing unit has a side pressing unit which is placed in front of the stone layer by means of a downward movement (downward arrow Fig. 8 C) and pushes this layer into place laterally, supported by a downwards pressing element (in this finger-shaped) that slightly presses on the first layer (down arrow Fig. 8 D) and ensures that it is first kept flat when moving and will also ensure that it
    -14- BE2019 / 5086 The first layer is kept in place when applying the adhesive (see eg.
    Fig. 8 E). A robot can be used for gluing the building blocks, which is equipped with a hose and nozzle.
    The robot applies adhesive mortar to the newly placed row of bricks according to a predetermined pattern.
    As explained in detail above, preferably in the contact angle between the bricks and the mounting plate (see e.g.
    Fig. 8 E) When stationary, the robot will spray briefly at certain times (depending on the drying time of the adhesive) to prevent drying out in the nozzle and any blockages.
    This time can be set via the control panel.
    There is also a water connection for flushing.
    After the adhesive has been applied, the pressure unit retracts and the next layer of bricks is prepared (Fig. 8 F). The pressing unit moves over the placed stones to a position with the lateral pressing lever past the last placed row of stones (Fig. 8 G). At this position the pressing unit lowers a downward pressing device on the previous row of stones placed to temporarily fix it on the bottom plate and the side pressing unit (Fig. 8 H) will lower in a subsequent movement the last placed row of stones in a horizontal (sliding movement). ) movement against the previous layer (Fig. 8 J). In order to prevent the last row from tilting during this movement, the pressing unit preferably contains additional pressers (downward arrow, Fig. 8 I), which press this row only slightly and, as it were, guide the stones in the horizontal sliding movement.
    The stones are preferably pressed by means of a servo motor.
    This servo motor can be perfectly positioned so that the distance between the rows of stones is always correct.
    The row to be pressed is clamped lightly (Fig. 8 I) to prevent the stones from tipping or sliding sideways during the pressing.
    The rows in front are clamped temporarily so that they cannot shift during pressing.
    After the construction element has been built up with the necessary layers, the bottom plate is transported to a drying tower by means of roller and chain conveyors.
    Because each bottom plate is provided with an RFID tag, the plc knows which element has been removed.
    This precast element is then automatically made back.
    At a later stage, the installation can be provided with a visual inspection, so that bad precast elements are automatically removed and remade.
    The drying tower consists of 4 towers, each with a capacity of 60 plates.
    So in total there are 240 places buffering.
    Two towers bring the plates upwards in a cycle and the other two towers bring the plates back down.
    -15- BE2019 / 5086 It has been decided to provide some overcapacity to ensure sufficient drying time. The drying towers are designed in such a way that they can be insulated later in order to obtain a faster drying time. Curing can possibly also be promoted by the use of a quick-drying compound.
    After drying, the assembled prefabricated element can undergo further treatments. In the installation described herein, these post-treatments include grinding a groove in the top and bottom of the precast element, applying a water spray and silicone to fix an aluminum reinforcement plate, applying a water spray and silicone in one of the slots. for attaching an aluminum joint mounting profile, and subsequently removing the post-treatment prefab elements for packaging and transport.
    A schematic overview of the total installation is shown in Figure 5, with the sawing and milling line in which the building blocks are calibrated in thickness and length and provided with a smooth stretching side. From the sawing and milling line, the treated building blocks end up in supply lines that also serve as a buffer for the masonry mounting unit. In the masonry mounting unit, the vertical prefab building elements to be placed on site are assembled horizontally during production on a base plate. On the labeled bottom plates, the assembled prefab building elements go to the buffering that comprises the drying towers, so that the bottom plates with the assembled prefab construction elements in this buffering have a passage, which allows a complete curing of the assembled construction elements. The hardened prefab building elements finally end up in the processing unit in which they undergo the aforementioned post-treatments. In this case, in particular for the application of the joint mounting profiles, the installation further comprises a profile bunker with aluminum saw for cutting the joint mounting profiles to length in function of the length of the slot in the precast building elements.
    These and further embodiments can be completed by a person skilled in the art on the basis of the wording of the following claims.
