Description

The present invention relates to a wall anchor for attaching a fall protection device to a house wall. The invention further relates to a building with such a wall anchor and a fall protection device attached to a building by such a wall anchor. On buildings, such as houses and halls, fall protection must be installed when working at heights to protect workers from falls. This fall protection is usually provided by scaffolding. Such scaffolding can be attached to the building using screws that are driven into the building's walls. On flat roofs, roof railings are used, which essentially form a railing that runs around the entire perimeter of the building. With a flat roof, the building's wall may extend vertically, so that an upper section of the wall projects above the roof. This overhang is called an attic. Attics are particularly well-suited for attaching roof railings. For example, brackets can be hooked onto the attic, extending over its top edge.Vertical components of a scaffold, such as poles or pipes, can be attached to these brackets and then connected to each other via horizontal components to form the scaffold or flat roof safety system. A disadvantage of this type of flat roof safety system is that the brackets attached to the parapet make the flat roof inaccessible in the parapet area. However, during building construction, the parapet on the flat roof side must be accessible, for example, to properly install a flat roof membrane. The same applies to repairs on completed buildings in the parapet area. Instead of such flat roof protection, a complete scaffolding of the building can also be used, but this involves considerably higher costs. Furthermore, it can hinder other work on the building's facade. US Patent 2010 / 0025151A1 discloses a wall anchor whose anchor has two hooks that are pivotable about a pivot axis relative to a support tube. To attach the anchor to an anchor receptacle permanently installed in the wall, the anchor, with its tube, is inserted longitudinally into the receptacle. For this purpose, the two hooks are arranged close together. The two anchors are then pivoted about the pivot axis so that they spread apart in the receptacle and engage an anchoring contour within the receptacle. From NL 10 19 494 C, a house wall anchor is known with an anchoring tube permanently installed in the house wall, which has a slot running vertically through it as its anchoring opening. The anchor has a bolt that can be pivoted 90° about a rotation axis between a release position, in which it can be inserted through the slot into the anchoring tube, and a locking position, in which it engages behind an opening edge of the slot. A similar house wall anchoring method is known from GB 25 44 173 B, in which the house-side anchoring structure has a vertically continuous slot into which an anchor can be inserted. From DE 32 12 634 A1 another house wall anchoring is known, in which a pin is inserted into a sleeve firmly installed in the house wall, wherein a bolt rotatable about an axis of rotation is arranged in the pin, which engages in a bolt opening formed in the sleeve in order to lock the pin inserted into the sleeve and thus secure it against being pulled out. German patent DE 10 2020 109 768 A1 discloses a conventional anchoring method for mounting a parapet to an attic. In this method, a support bearing is placed on the attic and screwed to it. A bracket for the parapet can then be attached to this support bearing. The present invention addresses the problem of providing an improved or alternative method for fall protection on a building, which in particular makes it possible to carry out work in the area of ​​an attic. At the same time, a cost-effective implementation of the fall protection can be pursued. This problem is solved according to the invention by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims. The invention is based on the general concept of attaching the respective fall protection system to a building wall using a wall anchor. The wall anchor comprises wall-side components that are permanently connected or connectable to the wall, as well as an anchor that is detachably connected or connected to the wall-side components and is configured for attaching the fall protection system. This allows the respective fall protection system to be attached to the building wall without requiring any interaction with an existing parapet. Thus, the parapet remains fully accessible for work. In the present context, a “configuration” is synonymous with a “design”, so that the phrase “configured so that” is synonymous with the phrase “designed so that”. The components on the house wall side consist of a cavity and an anchoring opening accessible from the outside of the wall, which connects the cavity to the outside of the wall. Furthermore, an opening edge that borders the anchoring opening forms another component on the house wall side. In particular, the components facing the building wall can be formed or provided using an anchoring tube that can be temporarily or permanently attached to the building. The anchoring tube can be attached to the outside of the building wall or recessed into the wall surface. The anchoring tube provides the cavity and an anchoring opening accessible from the outside of the wall, connecting the cavity to the wall surface. Furthermore, the opening edge, which defines the boundaries of the anchoring opening, is formed on the anchoring tube. Using the anchoring tube, the cavity, anchoring opening, and opening edge can be formed particularly easily on the respective building wall. In principle, however, any other method of creating the cavity, anchoring opening, and opening edge on the house wall is also conceivable. For example, a panel could be used that has the anchoring opening and the opening edge, while the cavity is formed by a recess or depression in the house wall. The panel can then be attached to the house wall in such a way that it more or less covers the recess, and the cavity remains accessible through the anchoring opening. The invention discloses a house wall anchoring system with an anchor, as well as a building and a panel facade with such a house wall anchoring system, and also a fall protection system which is attached to a house wall by means of such house wall anchoring systems. A house wall anchor according to the invention, which serves to attach a fall protection device to a house wall, comprises an anchor. The anchor has a longitudinal direction, a transverse direction perpendicular to the longitudinal direction, and a vertical direction perpendicular to both the longitudinal and transverse directions. The house wall anchor further comprises a straight anchor tube which runs parallel to the vertical direction and can be firmly connected to or within the outer surface of the house wall. This anchor tube has a cavity, an anchoring opening accessible from the outer surface of the wall which connects the cavity to the outer surface of the wall, and an opening edge which limits the anchoring opening at least in the vertical direction.The anchor has a support beam that extends in the longitudinal direction of the anchor from a bracket end of the beam to a hook end of the beam, the support beam having a bracket at its bracket end for receiving a component of the fall protection system. At its hook end, the support beam again has a hook that projects beyond the beam on both sides in the anchor's vertical direction to such an extent that the hook can be inserted into the cavity through the anchoring opening, which is smaller than the hook and larger than the beam in the anchor's vertical direction, by means of a rotational movement about an axis of rotation parallel to the anchor's transverse direction, and, with the anchor attached to the anchoring tube, is supported at the edge of the opening on both sides of the beam in the anchor's vertical direction.The anchoring tube makes it particularly easy to create the cavity, anchoring opening, and opening edge on the building's exterior wall. The anchor of this wall anchor can be configured in the same way as the previously described anchor, allowing for the same designs. The anchoring tube is preferably made of metal. In the wall anchoring system according to the invention, the anchor can be fixed to the wall from the outside, namely by inserting or penetrating the hook into the anchoring opening. The hook is dimensioned such that it cannot be pulled out of the anchoring opening along its length. The anchor, thus fixed to the wall, forms the wall anchoring system suitable for attaching fall protection. As mentioned, no interaction with any existing parapet is required. The anchor is preferably made of metal. The anchor can advantageously have a releasable locking mechanism that secures it against removal from the house wall when the hook is inserted into the cavity and supported at the edge of the opening. This increases the operational reliability of the house wall anchoring. According to an advantageous embodiment, the locking device can have a bolt opening and a bolt that can be inserted therein. The bolt opening can be formed adjacent to the hook on the support and penetrate the support in the direction of the anchor's height. Preferably, the bolt opening penetrates the support in the direction of the anchor's height. The bolt and bolt opening are advantageously aligned such that, when the hook is inserted into the cavity and supported at the edge of the opening, the anchor is secured against rotation about the axis of rotation by the bolt inserted into the bolt opening.Since the anchor is configured so that it can only be inserted into the cavity through the anchoring opening by a rotational movement of the hook, while a positive locking mechanism prevents the hook from being pulled out through the anchoring opening in the longitudinal direction of the anchor, the anchor's attachment to the house wall can be effectively secured by means of the locking bar, which prevents rotational movement of the anchor. The locking bar is preferably made of metal. According to an advantageous embodiment, the bolt and the bolt opening can be aligned in such a way that, when the hook is inserted into the cavity and supported at the edge of the opening, the edge of the opening can be clamped between the hook and the bolt in the longitudinal direction of the anchor by inserting the bolt into the bolt opening. Clamping or jamming the edge of the opening between the hook and the bolt ensures a particularly efficient way to secure the position and fix the anchor to the house wall. The bolt can be advantageously wedge-shaped, tapering in the insertion direction (where it is inserted into the bolt opening to secure the anchor to the house wall) relative to the anchor's longitudinal axis. Additionally or alternatively, the bolt opening can also be wedge-shaped, tapering in the insertion direction (where it is inserted into the bolt opening to secure the anchor to the house wall) relative to the anchor's longitudinal axis. The wedge-shaped design of the bolt and / or bolt opening makes it particularly easy to clamp the edge of the opening between the hook and the bolt when inserting the bolt into the bolt opening. In another embodiment, the bolt can have a locking opening at an end section preceding its insertion into the bolt opening. This locking opening penetrates the bolt in the transverse direction of the anchor. The bolt and the bolt opening can be aligned such that, when the bolt is inserted into the bolt opening, the locking opening is located in a portion of the end section that projects beyond the support in the anchor's vertical direction. The locking mechanism can also include a locking element that can be inserted into the locking opening and, when inserted, projects beyond the support in the transverse direction of the anchor, thus preventing the bolt from being pulled out of the bolt opening. The locking element secures the properly installed bolt to the anchor, preventing the anchor's attachment to the building wall, achieved by means of the bolt, from being accidentally released.The locking element is preferably made of metal. The locking element, which may be designed as a pin, cotter pin, or similar device, can optionally be connected to the bolt via a chain, cord, or rope. Furthermore, the anchor may have an additional opening, for example, on the bracket, into which the locking element can be inserted for transport or storage of the anchor. This securely fastens the bolt, which is separate from the anchor, to the anchor via the locking element and the chain, cord, or rope, thus facilitating ease of handling. The respective component of the fall protection system, which can be attached to the building wall using the anchor, can be, for example, a pole or tube, in particular a vertical pole or tube of scaffolding or railings. The anchor-side holder can then be a section of pipe extending in the direction of the anchor's height and having at least one axially open end, which is located at the top when the anchor is attached to the building wall, and through which the pole- or tube-shaped component can be inserted. This results in a particularly simple connection between the fall protection system and the anchor. Advantageously, the pipe section can be closed at an end furthest from the open end, or at least have a crossbar, so that the insertion depth of the rod- or tube-shaped component into the pipe section is limited. Here, too, additional securing measures are conceivable to secure the component inserted into the pipe section to the holder. In an advantageous embodiment, the anchor can have a diagonal brace at the bracket or at the bracket end, extending inclined to the anchor's vertical direction and inclined to its longitudinal direction. This brace includes a support located away from the bracket, which, when the anchor is attached to the building wall, bears against the building wall in the anchor's longitudinal direction. If the anchor is configured for a fall protection system designed as scaffolding or a parapet, the support can be configured to be comparatively long to ensure sufficient width for the walkway of the parapet or scaffolding. The large torques that occur during this process can be easily supported by the diagonal brace against the building wall.In particular, it is conceivable that the diagonal brace is firmly connected to the beam in the area of ​​the hook end by another brace extending especially in the direction of the anchor height, thereby achieving a particularly high support effect for the diagonal brace. Furthermore, it can optionally be provided that the diagonal brace has a support plate at its end, which bears against the house wall by means of a flat contact. If, however, the anchor is configured for a fall protection system designed as a flat roof safety barrier or railing, such a diagonal brace can generally be omitted, as the support beam is significantly shorter in this case. Unlike a parapet or scaffolding, a railing or flat roof safety barrier does not have a walkway. However, anchors without diagonal braces can also be used to construct a parapet or scaffold. For example, a scaffold component used to support a walkway could be braced using two anchors attached to the building wall, one above the other. The necessary moment support is then achieved through a suitable design of the scaffold component. A building according to the invention has at least one wall, which has at least one wall anchor of the type described above, wherein the respective anchor tube is attached in or to the respective wall. In other words, as soon as the anchor tube of the wall anchor according to the invention described above is attached to a building, a building according to the invention is formed. It is clear that, expediently, a plurality of such anchor tubes are attached to the respective wall. Furthermore, it is clear that in a building having several walls, at least one such anchor tube is attached to each of the several walls. In particular, so many anchor tubes can be attached to the walls of the building that a circumferentially closed fall protection system can be implemented. The building can suitably have a flat roof with a parapet that forms the upper end section of the respective building wall. The anchoring tube can then be attached to the building wall in the area of ​​the parapet, so that the wall anchor serves to secure a fall protection system designed as a flat roof safety barrier. This flat roof safety barrier can, in particular, consist of a railing. Additionally or alternatively, the respective anchoring tube can be attached to or within the building wall below the roof, so that the wall anchor serves to secure a scaffold or parapet designed as fall protection. A scaffold extends upwards from the ground along the building wall. In contrast, a parapet can be attached to the building wall at a distance from the ground. It is clear that the building can have several anchoring tubes on the respective house wall, spaced apart from each other in the vertical direction, so that both a flat roof protection system and a parapet or scaffolding can be attached to the building. In another embodiment, the building can have a panel facade on at least one wall, comprising several vertically extending panel supports attached to the exterior of the respective wall and several panels attached to the panel supports. At least one such panel support can be designed as an anchoring tube, either entirely or in at least one section, preferably in an upper end section associated with any parapet. In other words, the functionality of the anchoring tube for the wall anchoring system is integrated into the respective panel support of the panel facade. By mounting the panel supports to the wall, anchor points are thus created for the wall anchors, enabling easy attachment of the desired fall protection system to the wall.For example, this eliminates the need for a separate scaffold attached to the house wall. In particular, securing flat roofs is especially easy when the plate supports are designed as anchoring tubes in their upper end section, especially when the upper end section is located in the area of ​​an attic. Finally, a fall protection system according to the invention for a building is characterized by the fact that it is attached to a building wall by at least one wall anchor of the type described above. This fall protection system can be designed as scaffolding, a parapet, a flat roof safety barrier, or a railing. Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings. It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention as defined by the claims. Components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawings. Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components. Figure 1 shows, schematically, a sectional side view of a house wall of a building with an attic in the area of ​​a house wall anchor near the attic; Figure 2 shows a view as in Figure 1 in the area of ​​the house wall anchor in a different embodiment and spaced apart from a house roof; Figure 3 shows an isometric view of the house wall anchor with anchor and anchoring tube; Figure 4 shows a cross-section of the anchoring tube in the area of ​​an anchoring opening; Figure 5 shows a top view of the anchor; Figure 6 shows a longitudinal section of the anchoring tube in the area of ​​the anchoring opening; Figure 7 shows a longitudinal section of the anchor corresponding to section lines VII in Figure 5; Figure 8 shows a side view of a bolt with a locking element; Figure 9 shows a view as in Figures 1 and 2, but in a different embodiment; Figure 10 shows a highly simplified side view of a building with a panel facade and fall protection. According to Fig. 10, a building 1, shown only partially, has at least one wall 2, also shown only partially, to which a fall protection system 3 can be attached. In the example of Fig. 10, the building 1 is equipped with a panel facade 4 on the wall 2, which is attached to the wall 2. In particular, the wall 2 can be represented by vertical supports 5 to which the panel facade 4 is attached. Wall anchors 6 are used to attach the fall protection system 3 to the wall 2; these are explained in more detail below with reference to Figs. 1, 2, 3, 4, 5, 6, 7 to 8. As shown in Figures 1, 2, 3, 4, 5, 6, 7 to 8, such a house wall anchor 6 comprises an anchor 7 that defines a longitudinal anchor direction X, a transverse anchor direction Y, and an anchor vertical direction Z, all of which are perpendicular to each other. When properly installed on the respective house wall 2, the anchor vertical direction Z extends vertically, while the longitudinal anchor direction X projects perpendicularly from the typically vertical and flat house wall 2. This anchor 7 is attachable to the house wall 2 and has a support 8 that extends in the longitudinal anchor direction X from a holder end 9 of the support 8 to a hook end 10 of the support 8. At its holder end 9, the support 8 has a holder 11 for receiving a component 12 of the fall protection system 3. At its hook end 10, the support 8 has a hook 13 which is configured so that it extends in the anchor height direction Z on both sides, i.e. according to Fig. 3 and Fig.The hook 13 projects upwards and downwards beyond the support 8. The hook 13 is dimensioned in the anchor height direction Z such that it can be inserted through an anchoring opening 14 on the house wall 2, visible in Figures 2 to 4 and 6, into a cavity 15 on the house wall, also visible only in Figures 2 to 4 and 6. It is noteworthy that the hook 13 is dimensioned to be larger than the anchoring opening 14 in the anchor height direction Z. In contrast, the support 8 is dimensioned to be smaller than the anchoring opening 14 in the anchor height direction Z. In other words, the anchoring opening 14 is smaller than the hook 13 and larger than the support 8 in the anchor height direction Z. This ensures that the hook 13 can be inserted into the cavity 15 with a rotational movement around a space visible only in Figures 2 to 4 and 6.The pivot axis 16, indicated in Figure 3, can be inserted into and removed from the cavity 15 through the anchoring opening 14. The pivot axis 16 runs parallel to the anchor transverse direction Y. An opening edge 17, again only visible in Figures 2 to 4 and 6, is also provided on the house wall side and limits the anchoring opening 14 at least in the anchor vertical direction Z, but expediently also in the anchor transverse direction Y, thus leaving the anchoring opening 14 open in the anchor longitudinal direction X. The hook 13 is also configured such that it can be supported in the anchor vertical direction Z on both sides of the support 8 in the cavity 15 at the opening edge 17 in the anchor longitudinal direction X. For this purpose, the hook 13 is dimensioned larger in the anchor height direction Z than the anchoring opening 14. This prevents the hook 13 from being pulled out of the cavity 15 through the anchoring opening 14 in the anchor longitudinal direction X. The anchor 7 is equipped with a releasable locking device 18 that secures the anchor 7 against removal from the house wall 2 when the hook 13 is inserted into the cavity 15 and supported at the opening edge 17. In the embodiments shown here, the locking device 18 comprises a bolt opening 19 and a bolt 20 that can be inserted into the bolt opening 19. The bolt opening 19 is formed in the area of ​​the hook end 10, adjacent to the hook 13 on the support 8. The bolt opening 19 expediently penetrates the support 8 in the anchor height direction Z. The bolt 20 and the bolt opening 19 are expediently aligned with each other such that, when the hook 13 is inserted into the cavity 15 and supported at the opening edge 17, the anchor 7 is secured against rotation about the axis of rotation 16 by the bolt 20 inserted into the bolt opening 19.In other words, when the bolt 20 is installed, the anchor 7 can no longer be rotated about the axis of rotation 16, so that the hook 13 can no longer be removed from the cavity 15. Advantageously, the bolt 20 and the bolt opening 19 can be aligned such that when the hook 13 is inserted into the cavity 15 and supported against the opening edge 17, the opening edge 17 is clamped in the longitudinal direction X of the anchor between the hook 13 and the bolt 20. To achieve an efficient clamping effect, the bolt 20 can be wedge-shaped, such that the bolt 20 tapers in an insertion direction 21, indicated by an arrow in Figs. 3, 7 and 8, which runs parallel to the anchor height direction Z and in which the bolt 20 can be inserted into the bolt opening 19 to secure the anchor 7 to the house wall 2. Additionally or alternatively, as shown in Fig.7 provided that the bolt opening 19 is wedge-shaped, so that the bolt opening 19 tapers in the insertion direction 21. As shown in Figures 3 and 8, the bolt 20 can have a locking opening 23 at an end section 22, which precedes the bolt 20 when it is inserted into the bolt opening 19. This locking opening 23 penetrates the bolt 20 in the transverse direction Y of the anchor. The bolt 20 and the bolt opening 19 can be aligned such that, when the bolt 20 is inserted into the bolt opening 19, the locking opening 23 is located in a region of the end section 22 that projects beyond the support 8 in the anchor height direction Z. As shown in Figure 3, the locking opening 23 is thus located below the support 8. The locking device 18 can also be equipped with an additional locking element 24, which can be inserted into the locking opening 23 and, when inserted, projects beyond the support 8 in the transverse direction Y of the anchor, thus securing the bolt 20 against being pulled out of the bolt opening 19. In Fig.In Figure 3, the locking element 24 is inserted into the locking opening 23, so that the bolt 20 can no longer be pulled out of the bolt opening 19. The locking element 24 can be a pin, cotter pin, or the like. Figure 8 shows a pin-shaped locking element 24, which is also equipped with a locking spring 25 that prevents the locking element 24 from falling out of the locking opening 23 on its own. In the example shown in Figure 8, the locking element 24 is connected to the bolt 20 by a chain 26 to prevent it from being lost. According to Figure 7, an additional opening 27 can be provided on the anchor 7, for example, on the holder 11, into which the locking element 24 can be inserted when the bolt 20 is not in use. This ensures that the bolt 20 is securely connected to the anchor 7, which greatly simplifies the transport, storage and handling of the anchor 7 including the associated bolt 20. According to Figures 1, 2, and 10, the component 12 of the fall protection system, which can be attached to the house wall 2 using the anchor 7, can be a pole, which can also be hollow, i.e., designed as a tube. For example, it could be a scaffold pole or railing pole that extends vertically when the fall protection system 3 is installed and can be completed by horizontal components 28, such as further poles or tubes, to form the respective fall protection system 3. By way of example, in Figure 10, the fall protection system 3 shown there shows two adjacent vertical components 12 connected to each other by two horizontal components 28. According to Figures 1 to 3, 5 and 7, the holder 11 is expediently formed by a pipe section 29 extending in the anchor height direction Z and having at least one axially open end 30. When the anchor 7 is attached to the house wall 2, this open end 30 is located at the top, so that the rod-shaped component 12 of the fall protection 3 can be inserted into the pipe section 29 from above. According to Figures 5 and 7, the pipe section 29 can have a transverse web 31 in a region away from the open end 30, which limits the insertion depth of the rod- or tube-shaped component 12 into the pipe section 29. Instead of the transverse web 31, the pipe section 29 can also be closed in another way in the region away from the open end 30. Additionally or alternatively, it is conceivable to secure the respective component 12 in the pipe section 29 by a bolt that penetrates the pipe section 29 and the component 12. In the example shown in Figs. 3, 5 and 7, the support 8 and the hook 13 are formed by two flat bars connected to each other by a connecting web 32 and by the holder 11. The connecting web 32 is positioned such that it simultaneously limits the bolt opening 19 and, in particular, forms its wedge shape. In the example shown in Fig. 2, the anchor 7 at the bracket end 9 also has a diagonal brace 33, which is inclined to the anchor height direction Z and the anchor longitudinal direction X and which has a support end 34 located away from the bracket 11. The diagonal brace 33 is configured such that, when the anchor 7 is attached to the house wall 2, its support end 34 bears against the house wall 2 in the anchor longitudinal direction X. In the example shown in Fig. 2, the support end 34 is designed as a support plate for a large-area support. The diagonal brace 33 can optionally be supported on the beam 8 by means of a vertical brace 35. Advantageously, this vertical brace 35 is supported on the diagonal brace 33 in the area of ​​the support end 34 and on the beam 8 in the area of ​​the hook end 10.The embodiment with diagonal brace 33 is used in particular when the anchor 7 is intended for fastening a fall protection system 3 designed as a parapet or scaffolding, where a walkway is to be created on the fall protection system 3 using planks 36 or boards 36. In this case, the support 8 is dimensioned relatively large in the longitudinal direction X of the anchor, so that the bracket 11 has a relatively large distance to the house wall 2. In contrast, Fig. 1 shows an embodiment in which a fall protection device 3, designed as a railing or as a flat roof safety barrier, can be attached to the house wall 2 using the anchor 7. In this case, no walkway is required, so the support 8 can be made comparatively short in the anchor's longitudinal direction X. The bracket 11 is then arranged relatively close to the house wall 2. Fig. 1 also shows a configuration in which the building 1 has a flat roof 37 and a parapet 38. The parapet 38, in simplified terms, represents an upper end section of the respective house wall 2 that projects upwards above the flat roof 37. Using the anchor 6 presented here, the fall protection device 3 can be attached to the house wall 2 in the area of ​​the parapet 38 in such a way that the fall protection device 3 can be configured as a flat roof safety barrier. It is evident that there is no interaction with the parapet 38, so that it remains fully accessible for work.For example, this allows a cover 39 to be mounted on the parapet 38, which overlaps the house wall 2 or the respective vertical support 5 and the panel facade 4. Figure 9 shows another alternative embodiment in which the respective component 12 engages simultaneously with two house wall anchors 6, which are arranged vertically one above the other on the house wall 2 for this purpose. By means of a corresponding projecting shape of this component 12, it can also be used to support a plank 36 or panel 36, for example to create a walkway. Thus, a fall protection barrier 3, designed as a parapet or scaffold, can also be attached to the house wall 2 using the short anchors 7 mentioned above with reference to Figure 1. The house wall anchor 6 used here operates as described above with a cavity 15 on the house wall side, an anchoring opening 14 on the house wall side, and an opening edge 17 on the house wall side. According to Fig. 2, in a simple embodiment, the cavity 15 can be formed by a recess 40 cut into the house wall 2. The anchoring opening 14 and the opening edge 17 can then, purely by way of example, be formed on an anchoring plate 41, which is suitably and firmly connected to the house wall 2 and is positioned so that it closes the recess 40, thus forming the cavity 15, with the anchoring opening 14 being open to this cavity 15. However, the embodiment described in more detail below with reference to Figures 3, 4, 5, 6, 7, 8, 9 to 10 is preferred, in which the house wall anchor 6 is equipped with a straight anchoring tube 42 which, in the installed state of the house wall anchor 6, runs parallel to the anchor height direction Z and is firmly connected to or within an outer wall surface 43 of the house wall 2. This anchoring tube 42 has the cavity 15, the anchoring opening 14 accessible from the outer wall surface 43, which connects the cavity 15 to the outer wall surface 43, and the opening edge 17, which limits the anchoring opening 14. This anchoring tube 42 can now be attached to the respective house wall 2 in a suitable manner for the attachment of the fall protection device 3.A preferred configuration is one in which the anchoring tube 42 remains permanently attached to the house wall 2, so that the fall protection 3 can be easily reattached to the house wall 2 at a later time, for example, for repairs or maintenance work. For instance, one such anchoring tube 42 can be attached to the house wall 2 at regular intervals along the house wall 2. Mounting on the outer surface 43 of the wall is just as conceivable as mounting it recessed into the outer surface 43 of the wall. If, as in Fig. 1, the building 1 has a parapet 38, it may be advantageous to attach the respective anchoring tube 42 in or to the house wall 2 in the area of ​​the parapet 38. If the building 1, as indicated in Fig. 10, has a panel facade 4 on at least one wall 2, the respective anchoring tube 42 can be integrated into this panel facade 4. According to Fig. 10, the panel facade 4 has several panel supports 44, which are attached to an outer wall surface 43 so that they run vertically. Furthermore, the panel facade 4 comprises several panels 45, which are attached to the panel supports 44. The anchoring tubes 42 can be integrated into these panel supports 44, which are generally formed by hollow profile bodies. This allows at least one section of the respective panel support 44 to be designed as an anchoring tube 42. The panel support section designed as an anchoring tube 42 is labelled 46 in the figures and can, in particular, be located in an upper end section of the respective panel support 44, which is associated with the parapet 38.To implement a flat roof safety system, several plate girders 44 can have plate girder section 46 designed as an anchoring tube 42 in their upper end section. In order to easily install a fall protection system 3, for example in the form of a parapet or scaffolding, below the upper end of the respective house wall 2 and above a floor 47 from which the respective side wall 2 of the building 1 rises, the plate girders 44 can have at least one, preferably several, plate girder sections 46 designed as anchoring tubes 42 along their vertical extension, so that scaffolding or a parapet can be attached to the building 1 at any time without damaging the plate facade 4. In the case of a plate support 44, which is designed as a hollow profile body, the integration of the respective anchoring tube 42 can be achieved particularly easily by providing the anchoring opening 14 at a suitable location in the plate support 44. The cavity 15 is formed by the interior of the hollow profile body, and the opening edge 17 is formed by the remaining material of the plate support 44. In the example shown in Fig. 9, a common anchoring tube 42 can be used for the two anchors 7 arranged one above the other in the anchor height direction Z. This tube is equipped with two anchoring openings 14 that are spaced apart from each other. Alternatively, two anchoring openings 14 can be provided in the continuous plate support 44 at the corresponding locations.
