    Steam anchor device
    BACKGROUND OF THE INVENTION
    The invention relates to a scaffolding anchoring device for fixing a scaffolding erected on a surface to a wall.
    The invention further relates to a method for anchoring the scaffolding with the wall with the aid of such a scaffolding anchoring device.
    Such scaffolding anchoring devices are used in construction in scaffolding constructions with which workplaces are provided at heights for persons who, for example, perform work on an outside of the wall, such as for example an inner wall. These activities may include the installation of insulating material, the bricklaying of an outer wall that must be erected between the inner wall and the scaffolding, and the joining of the outside of the outer wall.
    Such scaffolding is constructed by coupling scaffolding pipes to each other with the aid of scaffolding pipe couplings and is supported vertically on a generally unpaved soil of a construction site. In the case of scaffolding comprising several storeys placed one above the other, such scaffolding, such as for example in the high-rise, is also coupled to the inner wall at certain heights, for anchoring the scaffolding.
    For anchoring the scaffolding, scaffolding tubes are used which are provided at one end with a head plate welded to the head of a scaffolding tube, which head plate is provided with a through opening for fixing the head plate to or against the wall by means of a bolt .
    If now an outer wall comprising a brickwork must be erected between the scaffolding and the inner wall, a few stones must be spared when bricklaying the outer wall in order to keep these scaffolding tubes accessible for disassembly, and near the scaffolding pipes mounted against the wall. To provide a sufficient passage for dismantling, the number of stones that cannot be placed can easily be four to five.
    During the dismantling of the scaffolding at the location of a scaffolding tube that has been removed, the outer wall must be bricked up with one or more suitable bricks. This means that both the dismantling of the scaffolding and the bricklaying of the recesses is not efficient. Apart from a less efficient working process, a brickwork of the outside wall afterwards can lead to a disturbance in the brickwork, such as crooked and / or too deep or too shallow brickwork. Color differences can also occur, both with regard to the bricks that can originate from different manufacturing processes, and with regard to the grooves to be joined whose mortar is composed in a different mixing ratio or from mortar with a different color.
    It is an object of the present invention to provide an alternative scaffolding anchoring device which is easy to use when carrying out work from the scaffolding with which, for example, keeping large recesses in the outer wall including a brickwork can be prevented.
    SUMMARY OF THE INVENTION
    The invention provides a scaffolding anchoring device comprising a wall mounting body and an arm extending away from the wall mounting body and connected thereto at a first position of the wall mounting body, wherein the wall mounting body comprises mounting means for mounting the wall mounting body on or against a first wall at a second position thereof, wherein the first position is spaced relative to the second position, wherein the fixing means and / or the wall mounting body, in its mounted state against the first wall, are adapted to adjust a position of the arm relative to the first wall, wherein at least a part of the arm is detachable from the wall mounting body, and wherein the wall mounting body extends on either side of the second position.
    Because the mounting means and / or the wall mounting body are adapted to adjust a position of the arm relative to the first wall, it becomes possible to adjust the position of the arm relative to the first wall after the mounting means and / or the wall mounting body are placed against the first wall. As a result, the arm in the work can be brought into a desired position relative to the first wall for anchoring a scaffolding on the first wall.
    Because at least a part of the arm is detachable from the wall mounting arm, accessibility of the mounting means and / or the wall mounting body for dismantling the scaffolding anchoring device is not required. When dismantling the scaffolding, it is sufficient to remove the detachable arms with regard to dismantling the scaffolding anchor devices. It is noted here that the fixing means and / or the wall fixing body remain on the inner wall and cannot be reused when building the scaffolding in another application. Against this price is the advantage that the scaffolding anchoring device is easy to dismantle due to the detachability of the arm relative to the fixing means and / or the wall fixing body, the arm moving within a space that can be limited to a space that the arm is in an the wall mounting body assumes a confirmed condition and extends in line therewith.
    In one embodiment, the arm is connected to the wall mounting body via a screw connection. This makes it possible to remove the arm, which in the mounted state formed a firm connection or anchoring with the first wall, by a rotation about the longitudinal axis of the arm, whereby the arm moves within a space that can be limited to a space occupied by the arm in a state attached to the wall mounting body and extending therefrom.
    In one embodiment the arm comprises, near an end remote from the wall mounting body, a connecting means for connecting the arm to a scaffolding. In one embodiment the connecting means is provided with an eye for engaging a hook arranged on the scaffolding or connected to the eye and engaging with it.
    In one embodiment, the fixing means of the wall mounting body comprise a through opening for passing a wall mounting through it. The wall-mounting body can be set in a rotation-free state in a position in which, after determining a desired angle, it is rotatable with the first wall; can be coupled, for example, by screwing on with a fastener in the form of a bolt.
    In one embodiment, the through-opening comprises a slotted hole. In a rotation and translation-free state, the wall-mounting body can be placed in a position in which, after determining a desired angle and location, it can be coupled to the first wall in a rotation-proof and translation-proof manner.
    In one embodiment, the wall mounting body extends on either side of the second position. In one embodiment, the wall mounting body extends symmetrically with respect to the second position. Hereby it becomes possible to achieve a desired angle of the wall mounting body by a rotation with respect to the fixing means of at most 180 degrees. Apart from this, a wall mounting body that extends on a side of the second position remote from the first position, preferably symmetrically with respect to the second position, can be used to support the wall mounting body against the wall.
    In one embodiment, a thickness of the arm is arranged to reach through a joint of a second wall comprising a brickwork that is and / or is raised between the scaffolding and the first wall.
    In one embodiment, the arm has a thickness that is less than 20 mm. The arm can now be placed in a joint of the second wall. It is then no longer necessary to keep a recess of one or more stones open at the location of the anchoring during bricklaying the outer wall.
    In one embodiment, the arm is arranged in a longitudinal direction to extend through an outer surface of a second wall comprising a brickwork that is and / or is raised between the scaffolding and the first wall. In one embodiment the arm has a length of at least 150 mm. The connecting means of the arm can extend beyond the outward facing surface of the second wall, whereby the coupling with a scaffolding is placed outside the outer wall. This makes it possible, when dismantling the scaffolding connected to the first wall via the scaffolding anchoring device, after bricking the second wall, to disconnect outside the second wall from the connecting means of the arm of the scaffolding anchoring device.
    In one embodiment, a sleeve is at least partially placed loosely around the arm. This measure provides a possibility to protect an outer peripheral wall of the arm against an influence of grout or cement that is applied against it during the bricking of the arm in the second wall.
    In one embodiment, the sleeve can be made of metal. However, the sleeve is preferably made of plastic for preventing a thermal bridge between the first and the second wall.
    In one embodiment, the inner circumferential wall of the sleeve is adapted to enclose a circumferential wall of the arm.
    In one embodiment the sleeve is placed against the wall mounting body at least near its first position. In one embodiment, the first position of the wall mounting body is provided with an upstanding edge for an adjacent connection of a circumferential wall of the sleeve. By simply placing the end of the sleeve facing the wall mounting body against the upstanding edge of the wall mounting body, the sleeve can be connected thereto, the end of the sleeve being enclosed laterally. Moreover, after the scaffolding anchoring device has been placed and the second wall has to be bricked up, the sleeve becomes further clamped in it, as a result of which the freedom of movement and / or movement of the sleeve is very limited. When dismantling the scaffolding, the arm can be removed while the sleeve remains in the second wall. The sleeve can later be used again, as in the case of a rebuilding of the scaffolding, when reassembling an arm against the first wall. Upon inserting an arm into the sleeve again, the arm moves through the second wall that has already been bricked in and the end of the arm facing the wall mounting body is guided through the sleeve to the first position of the wall mounting body for coupling thereof to the first position of the wall mounting body.
    In one embodiment, the sleeve is provided with fixing means which are adapted to hold the sleeve in a substantially same position with respect to the second wall when the arm retracts. In one embodiment, the fixing means extend radially from an outside of the peripheral wall of the sleeve in a direction away from an axis of the sleeve.
    In one embodiment, the fixing means are positioned for abutting in use against a surface of the second wall facing the first wall.
    In one embodiment the fixing means comprise projecting parts directed towards the inside of the second wall for engaging the inside of the second wall. This measure makes it possible to couple fixation means, for example by bricklaying, with the surface of the second wall facing the first wall.
    In one embodiment the fixing means are slidable over the sleeve, at least in a direction away from the wall fixing body. This makes it possible, during bricklaying, to move the fixing means to a desired position of the sleeve in a simple manner from the end of the sleeve facing the wall mounting body, the desired position of the fixing means on the sleeve being determined by the location where the sleeve extends through the face of the second wall facing the first wall.
    In one embodiment the sleeve is provided with blocking means which are adapted to block a displacement of the fixing means relative to the sleeve in a direction facing the wall mounting body. In one embodiment, the blocking means comprise a series of barbs extending in the longitudinal direction of the sleeve, preferably sawtooth-shaped barbs, wherein the fixing means are provided with a blocking part, for example a resilient lip, which forms a form-fitting connection with the barbs.
    According to a second aspect, the invention provides a building comprising one or more scaffolding anchor devices as described above.
    According to a third aspect, the invention provides a building comprising one or more wall mounting bodies for a scaffolding anchoring device. The presence of wall mounting bodies on an inner wall in the cavity indicates a use of the invention during construction. In addition, in such a building use can be made of the openings in a joint of the outer wall which, after the previous use, have been left behind either in the open state or have been closed and marked, for re-arranging arms for providing a scaffolding anchorage or a fixing point to attach something to the facade.
    According to a fourth aspect, the invention provides a use of a scaffolding anchoring device as described above for anchoring the scaffolding with the first wall. By using the scaffolding anchoring device according to the invention, it can be positioned such that the arm extends at the location of a brick or even of a joint of the second wall comprising a brickwork. The arm preferably has a thickness that is smaller than a thickness of the joint, as a result of which the fixation can be placed entirely within the joint.
    According to a fifth aspect, the invention provides a use of a scaffolding anchoring device as described above, wherein the scaffolding comprises a coupling tube for coupling to the scaffolding anchoring device. In one embodiment, the coupling tube is extendable, preferably telescopic. A scaffolding can hereby be coupled to a scaffolding anchoring device, wherein a length of the extendable coupling tube can be easily adjusted for coupling to the connecting means of an arm of the scaffolding anchoring device. In a specific case where during use of a scaffold short arms are initially used and later have to be replaced by longer arms, the scaffolding can be coupled to the longer arm by a corresponding adjustment of the length of the extendable coupling tube.
    According to a sixth aspect, the invention provides an extendable coupling tube for a scaffold as described above.
    In an embodiment, the extendable coupling tube comprises locking means for securing the length of the extendable tube at a number of preferred positions along the extendable tube. This measure provides the extendable tube with a number of preferred positions to which a first portion of the tube can be fixed relative to a second portion of the tube, the positions being dependent on a length of the arms used as standard.
    According to a seventh aspect, the invention provides a method for anchoring a scaffold with a first wall by means of a scaffolding anchoring device, comprising the steps of: attaching the scaffolding anchoring device to a first wall by means of the fixing means, coupling an adjacent the scaffolding placed on the arm on the first wall, wherein, after the scaffolding anchoring device has been attached to the first wall, a position of the arm relative to the first wall can be adjusted.
    In one embodiment the method comprises a step in which a second wall comprising a brickwork is between the scaffolding and the first wall and / or is raised, wherein the arm connected to the wall mounting body is brought into a position such that the arm is at least substantially against one side of a brick of the second wall placed near the arm before continuing to build the brickwork. This makes it possible that during the bricklaying of the second wall the arm of a scaffolding anchoring device can be brought into a position wherein the arm extends through a position of one brick or a joint. After the second wall has been bricked in its entirety, the scaffolding can be detached from the scaffolding anchoring devices during disassembly of the scaffolding, whereafter the arm of a scaffolding anchoring device can also be detached without having to grant passage to the mounting means and / or the wall mounting body. This makes it possible to disassemble only the arm, which only requires such a small space that this space can extend within the dimensions of one brick or preferably a joint, so that the saving of bricks in the second wall can be limited or even appearance.
    The aspects and measures described in this description and claims of the application and / or shown in the drawings of this application can, where possible, also be applied separately from each other. These individual aspects can be the subject of split-off patent applications that are aimed at this. This applies in particular to the measures and aspects that are described per se in the subclaims.

    DETAILED DESCRIPTION OF THE DRAWINGS
    Figure 1 shows a scaffolding anchor device 1 according to the invention. The scaffolding anchoring device comprises a wall mounting body 2 which in this example is elongated in shape and extends along a direction R, wherein the wall mounting body 2 is provided in the middle with a through opening 21 through which, in this example, a bolt 20 can be inserted for mounting. attaching the wall mounting body 2 to a wall. The through-opening 21 has a first axis 24 which substantially coincides with a axis 25 of the bolt 20 and which extends substantially transversely both to the direction R and to a first normal surface 26 of the wall-mounting body 2.
    Through the continuous round opening 21 of the wall mounting body 2 the wall mounting body 2 can rotate relative to the bolt 20.
    In this example, the wall mounting body 2 has a width B in the middle in a direction that extends substantially transversely to the direction R and extends substantially parallel to the normal surface 26. The center of the wall mounting body 2 extends along the direction R a first end 28. From the center of the wall-mounting body 2 extends in a direction opposite to the direction R to a second end 29 which is remote from the first "end 28. In this example, a width of the wall-mounting body 2 extends from the center to an end 28 29, from a width B to a width that is smaller than the width B at the center of the wall-mounting body The wall-mounting body 2 may, as the following figures show, also be provided with a constant width B.
    Near the first end 28 of the wall-mounting body 2 there is a first opening 22 which has a center line which is substantially parallel to the center line 24 of the through-opening 21. The first opening 22 in this example is provided with internal screw thread.
    Near the second end 29 of the wall mounting body 2 is a second opening 23 which has a center line which is substantially parallel to the center line 24 of the through-opening 21. The second opening 23 is provided with internal screw thread (not shown), wherein in the drawn situation a first end 31 of an arm 3 is placed in the second opening 23. The arm 3 in this example is designed as an eye bolt 3. The eye bolt 3 is provided with an external screw thread 30 near the first end 31 and engages on internal thread of the second opening 23. The first end 31 of the eye bolt 3 is adapted to be connected to either the first opening 22 or to determine the second opening 23 optionally during the mounting of the wall mounting body 2 against a wall.
    The eye bolt 3 comprises a second end 32 remote from the first end 31 and provided with an attachment part 33 which is in the form of a closed ring. The top part 33 encloses a space 34 which is suitable for engaging a hook 93 provided by a scaffolding tube 91 for example in figure 2.
    Figure 2 shows a scaffolding anchoring device 1 for anchoring a scaffolding of which only two scaffolding tubes 91, 92 are shown. During the construction of a building, the scaffolding is coupled via the scaffolding anchoring device 1 to a first wall 4. Such a first wall 4 is, for example, arranged as an inner wall and functions as a load-bearing wall to absorb loads. Such walls are often made of concrete or a brickwork.
    Figure 2 shows an outwardly facing side 41 of the first wall 4. The wall mounting body 2 of the scaffolding anchor device 1 is connected to the first wall 4 by means of a bolt 20, for example a screw bolt or spanner bolt. After the scaffolding is placed and against the first wall 4 is anchored, a second wall 5, for example an outer wall 5, is placed between the first wall 4 and the scaffolding.
    A cavity 6 known per se is formed between the first wall 4 and the second wall 5, which cavity is possibly provided with insulating material 61.
    The second wall 5 is erected by brick bricks 52, 53, 54 according to a pattern that is known per se.
    Figure 2 shows a situation in which the scaffolding anchoring device 1 is mounted against the outward facing side 41 of the first wall 4. The wall mounting body 2 lies with a second normal surface 27 remote from the first normal surface 26 of the wall mounting body 2 against the outward facing side 41 of the first wall 4, with an inwardly facing surface of the head of the bolt 20 abutting the first normal surface 26 of the wall-mounting body 2. The eye bolt 3 is arranged in the first or second opening 22, 23 such that the eye 34 of the annular attachment 33 faces away from the outward facing side 41 of the first wall 4.
    Figure 2 shows a scaffolding tube 91 comprising a hook 93 near one end of the scaffolding tube 91, which hook 93 is inserted through the eye 34 of the annular attachment 33 of the eye bolt 3 for coupling the scaffolding to the first wall 4 via the scaffolding anchoring device 1. The eye bolt 3 is at a distance A from an upper side 55 of a first brick 54 of the partially bricked second wall 5. The eye bolt 3 crosses the second wall 5 at the location of a second brick 56 to be fitted (shown) in Figure 4). When the second wall 5 is further bricked up, the eye bolt 3 is an obstacle for placing at least one second brick, as a result of which the second wall 5 cannot be completely bricked up, but whereby a brick must be spared at the location of the obstacle.
    Figure 3 shows substantially the same parts as shown in Figure 2. However, the eye bolt 3 rests against the upper side 55 of the first brick 54 of the partially bricked-up second wall 5, after the wall-mounting body 2 relative to the position as shown. 2 is rotated through an angle B about an axis which substantially coincides with the axis 24 of the through-opening 21. Thus, the wall mounting body 2 can be brought into the desired position. In order to prevent the eye bolt 3 from continuing to function as an obstacle to bricking the second wall 5, the eye bolt 3 can be brought near or against the upper side 55 of the first brick 54 of the partially bricked second wall 5. In this exemplary embodiment, the thickness of the eye bolt 3 is smaller than a thickness of the joint 57.58 (shown in figures 3 and / or 4). In this case, no stones need be spared, and when the second wall 5 is further bricked in, the eye bolt 3 can be placed in the joint 57, 57, so that the second wall 5 can be completely bricked up. The eye bolt 3 extends through the layer of mortar, the eye bolt 3 extending through the outward facing surface 51 of the second wall 5, the eye 34 being located outside the second wall 5, as shown in Figure 4.
    Joints in brick masonry generally have a maximum thickness of 14 mm. For brickwork patterns known per se, eye bolts 3 have a preferred thickness of 10 mm or 12 mm.
    Building construction known per se comprising a first wall 4 and a second wall 5 enclose a cavity 6, the distance between the first wall 4 and the second wall 5 being at least 50 mm. If the second wall 5 has a thickness of 100 mm, a length of the arm 3 should be at least 150 mm, the length still to be increased by a length of the annular attachment 33 which still needs to be at least a certain distance outside the outer wall can reach. The total length of the eye bolt 3 thereby comes to 200 mm. For thicker cavities 6, the length of the eye bolt 3 should be correspondingly greater, while the length of the eye bolt 3 can be up to, for example, 250 mm, 270 mm or 300 mm.
    After bricking the second wall 5, the second wall 5 can be added. After all work to be done from the scaffolding has been completed, the scaffolding can be dismantled from top to bottom. During the dismantling of the scaffolding, the eye bolts 3 can remain attached to the first wall 4 or can be loosened and collected for reuse when erecting the scaffolding at a next construction site. When the eye bolts 3 are detached, through-openings (not shown) are created in the joint that can optionally remain open for reuse in scaffolding for possible renovation work in the future. Optionally, such through-openings can be filled with a closing cap, a joint grout or an alternative filling means during the dismantling of the scaffolding.
    Figure 5 shows an alternative embodiment of the invention with a through-hole 21 in the form of a slotted hole. Hereby it is possible that when positioning the scaffolding anchoring device 1 the wall mounting body 2 can rotate and translate relative to the bolt 20, which provides a greater adjustment possibility for placing the wall mounting body 2 relative to the first wall 4.
    Figure 6A shows a further alternative embodiment of the wall-mounting body 2, which is substantially circular, the through-opening 21 being substantially in the center of the wall-mounting body 200. The first opening 22 and the second opening 23 of the wall-mounting body 200 are substantially at the same distance from the opening 21, the first opening 22 and the second opening 23 being arranged substantially symmetrically with respect to the opening 21.
    Figure 6B shows a cross section along the line VIB-VIB of Figure 6A. The circular wall mounting body 200 in this example is in the form of a dish, the opening 21 of which is at a distance h from a plane through the peripheral edge of the wall mounting body 200. In this example, the first opening 22 of the wall mounting body 200 is provided with a first welded nut 202 (M12) and the second opening 23 is provided with a second welded nut 203 (M10). In this example, the first nut 202 is larger than the second nut 203, the first nut 202 being suitable for attaching a thicker eye bolt 3 than an eye bolt 3 suitable for attaching to the second nut 203. The use of larger thicknesses of eye bolts 3 may be desirable, for example, when the eye bolts 3 are exposed to a greater load, such as, for example, scaffolding constructions in the high-rise building. For the interchanging of eye bolts 3.30 whose thickness and / or length is different, universal wall mounting bodies 2 can be used by providing welded nuts 202,203 different dimensions.
    Figure 7 shows an eye bolt 30 that has a first length L that is shorter than the eye bolt 3 that has a second length M as shown in Figure 5. During the construction of the scaffolding prior to bricklaying the second wall, scaffolding anchoring devices 1 can be applied with eye bolts 30 being short. The use of short eye bolts 30 may be required when a scaffolding can be exposed to a high load, for example in the high-rise building, whereby large wind loads can occur on the scaffolding. During the bricking of the second wall 5, the short eye bolts 30 no longer reach the outer surface 51 of the second wall 5 and must be detached and removed after the scaffolding of the short eye bolts 30 to be removed has been disconnected by the hook 93 from the eye 340 to be taken from the eye bolts 30. An eye bolt 3, the length M of which is longer, can then be coupled to the wall mounting body 2, whereafter the scaffolding tube 91 can be coupled to the eye bolt 3 by the hook 93 in the eye 34 of the eye bolt 3. with the second length M.
    Because the eye bolt 30 of the first length L has been replaced by the eye bolt 3 of the second length M, the scaffolding tube 91 comprising the hook 93 must be moved over a corresponding distance and direction, wherein it is necessary to release at least one scaffolding tube coupling and, after the scaffolding tube 91 has been moved sufficiently, to be fixed again. The adjustment of the scaffolding tube 91 can be prevented by using an extendable scaffolding tube 9 according to figure 8 for coupling the scaffolding to the scaffolding anchoring device 1.
    The extendable scaffolding tube 9 comprises a first tube 91 with a first end 911, and a second end 912 that faces away from the first end 911. Between the first end 911 and the second end 912 of the tube 91, the extendable tube 9 can be coupled to parts of the scaffolding.
    The extendable scaffolding tube 9 comprises a second tube 95 with a first end 951 provided with a hook 94 which is suitable and intended for engaging the eye bolt 3.30 in the eye 34,340. The second tube 95 comprises a second end 952 remote from the first end 951, which is arranged so as to be movable in the first tube 91. Thus, the second tube 95 can slide into the first tube 91.
    Figure 8 shows a first and a second through opening 96.97 in a circumferential wall of the first tube 91. The second tube 95 comprises, near its second end 912, a third opening 98 which is provided with a screw thread on which an adjusting screw (not shown) can engage which set screw can optionally extend through the first opening 96 or the second opening 97 of the first tube 91 into the third opening 98 of the second tube 95. By connecting the first opening 96 with the third opening 98 to the adjusting screw, the extendable scaffolding tube 9 can be brought into a first position, the second tube 95 being fixedly coupled to the first tube 91. The first position of the extendable scaffolding tube 9 can be used when scaffolding anchor devices 1 with short eye bolts 30 of the first length L are attached to the first wall 4.
    The extendable scaffolding tube 9 can be brought into a second position by loosening the set screw, inserting the second tube 95 deeper into the first tube 91, until the second opening 97 of the first tube 91 is in front of the third opening 98 of the second tube 95, after which the adjusting screw can be inserted and tightened. The second position of the extendable scaffolding tube 9 can be applied when scaffolding anchoring devices with long eye bolts 3 of the second length M are attached to the first wall 4.
    In the specific situation, a distance N between the first opening 96 of the first tube 91 and the second opening 97 thereof is substantially equal to the difference in length between the short eye bolt 30 with the first length L and the long eye bolt 3 with the second length M.
    The extendable tube 9 can alternatively be fixed in the first position by inserting a locking pin through successively the first opening 96, the third opening 98, and diametrically from the third and first openings 98.96 opposite openings in the second tube respectively 95 and the first tube 91. After fitting the locking pin in the extendable tube 9, the locking pin extends thoroughly through the extendable tube 9, which is thereby fixed in the first position. The extendable tube 9 can be fixed in the second position in an analogous manner.
    Figure 7 further shows a wall-mounting body 2, wherein at the position of the first position and near the through opening 22,23 a raised edge 220,230 is arranged on the first normal surface 26. This upstanding edge 220, 230 is arranged to position a first end 301 of a sleeve 300. An outer diameter of the sleeve 300 is here embodied such that the first end 301 of the sleeve 300 can be inserted into the raised edge 220,230, the outer diameter of the first end 301 of the sleeve 300 closely connecting to an inner diameter of the cylindrical body 220,230 . In an alternative embodiment, which is not shown, an inner diameter of the first end 301 of the sleeve 300 can be designed such that the first end 301 of the sleeve 300 fits tightly around an outer diameter of the raised edge 220,230.
    The sleeve 300 is suitable for and intended to remain permanently in the second wall 5 to be laid in brickwork after removal of the scaffolding anchoring device 1. Thus, later, for example for renovation work on the outside 51 of the second wall 5 , a scaffold can be built up, wherein the eye bolt 3 can be inserted into the sleeve 300, which thus acts as a guide device for guiding a threaded first end 31 of the eye bolt 3, which first end up to near the first position of the wall mounting body 2 230 is inserted for tightening the eye bolt 3 in the threaded opening 22,23 of the wall mounting body 2.
    The sleeve 300 is placed on the eye bolt 3 before or during the bricking of the second wall 5, preferably before or during the adjustment of the position of scaffolding anchoring device 1, as it can be bricked in. The bricklayer can thereby shorten the sleeve 300 to a desired length of the sleeve 300, because the distance between the surface 41 of the first wall 4 facing the second wall 5 and the outer surface 51 of the second wall 5 can be determined with sufficient accuracy. For example, after the eye bolt 3 has been temporarily unscrewed from the wall mounting body 2, the sleeve 300 can be slid over the eye bolt 3 via the first end 31 of the eye bolt 3.
    When the scaffolding is dismantled, the eye bolts 3 of the scaffolding anchor devices 1 are loosened and withdrawn from the sleeve 300. In order to keep the sleeve 300 in place, a flange or ring 390 is placed on the sleeve 300, which acts as a fixing means.
    On the one hand, the flange or ring 390 can be fixedly connected to the sleeve 300, wherein during setting of the position of the scaffolding anchoring device 1, the sleeve 300 is shortened such that the flange or ring 390 near or against the surface facing the first wall 4 of the second wall 5. In a simple embodiment, the sleeve 300 is made of plastic, wherein the flange or ring 390 can be integrally formed with the sleeve 300.
    On the other hand, the flange or ring 390 can be slidably placed on the sleeve 300. When the sleeve 300 is placed on the eye bolt 3, the flange 390 from the first end 31 of the eye bolt 3 can be slid over the sleeve 300 in the direction of the second end 32. A displacement of the flange 390 in the opposite direction is not possible by a form-locked connection between the flange 390 and the sleeve 300 based on barbs, as Figure 10 shows. This form-fit connection can be made as in the case of a "tie-wrap" in which the sleeve 300 is provided with a band provided with a toothing 306, and the flange 390 is provided with a resilient lip 393 in one direction S, while the resilient lip 393 blocks movement of the flange 390 in the opposite direction. As a result, a sleeve 300 mounted in the wall can be held in place when, for example, the eye bolt 3 is pulled out of the sleeve 300.
    Figure 9 shows a scaffolding anchoring device 1 which is mounted against the first wall 4 not shown herein, wherein the eye bolt 3 coupled to the wall mounting body 2 is positioned in a joint 58, which eye bolt 3 is provided with the sleeve 300, the flange 390 being substantially against the side of the second wall 5 facing the first wall 4. After the eye bolt 3 has been removed, the sleeve 300 can be closed with a cap (not shown) to prevent air, and in particular moisture, from entering the cavity 6 via the sleeve 300 from the outside.
    The above description is included to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. For example, the second wall can be made of bricks of a previously undetermined shape, such as rough stones from a mountain range, but also certain shapes, such as bricks. The invention is not limited to application comprising a second wall of stone; the second wall can also be constructed from concrete blocks or cement blocks of a form that is predetermined or predetermined. Starting from the above explanation, many variations will be evident to those skilled in the art that fall within the spirit and scope of the present invention.
