Description

[0001] The invention lies in the field of temporary parapet systems (also known as fall protection, side protection, or edge protection systems) for building roofs, particularly for use during maintenance work on a pitched roof. Maintenance work is understood to mean work that arises after the completion of the building roof. Such maintenance work includes, in particular, roof repairs, coating work, and the installation of technical equipment on a building roof, whereby the technical equipment to be installed includes, in particular, radio masts, measuring equipment, or photovoltaic systems.

[0002] In practice, permanent parapet systems for building roofs are known, which are permanently anchored to the building. On the other hand, it is also known to install a temporary parapet at a roof edge to protect workers on the roof and / or loads stored on the roof from falling. The temporary parapet typically comprises a frame with multiple support posts, which are placed essentially upright at or in front of the roof edge, as well as one or more railing sections that are attached to the frame and extend essentially horizontally.

[0003] Known parapet systems can be distinguished according to their intended mounting method into, on the one hand, systems with screw piles, in which the support piles are anchored to a building component directly via a screw connection or by means of a rigid fitting, and, on the other hand, parapet systems with clamping piles, in which the support piles are fixed to a building component by means of a clamping device. Such parapet systems are known, for example, from DE 202014100056 U1, WO 98 / 20215 A1, WO 2008 / 019499 A1, US 2010 / 0314199 A1, US 2005 / 0247518 A1 and DE 4415827 A1.

[0004] These previously established systems using screw piles or clamp piles have the disadvantage that they are either only usable during the initial construction of the building, because their installation requires drilling holes in the building's exterior or interior walls, and / or because they require an open wall end to which clamping can be applied. Furthermore, such systems are complex to handle, and during the lengthy assembly and disassembly phases, they provide little or no protection. Therefore, they are rarely used for maintenance work.

[0005] A significant improvement in protective effect was achieved through the edge fall protection systems with adjustable posts addressed in the present application. Such a system is published in WO 2003 / 093609 A1. In this system, the support posts of the frame are designed as adjustable posts and can be inserted particularly quickly into a channel provided on-site, located directly in front of the roof edge, for example, a rain gutter. For this reason, such systems are referred to below as adjustable post edge fall protection systems.

[0006] A bracket that can be attached either to an attic or to a roof gutter is known from DE 10 2011 102 486 A1. This bracket is said to have the advantage that it is not necessary to install any fasteners in the building structure for mounting.

[0007] From DE 196 02 047 A1, a roof safety scaffold is known that includes a so-called backrest, which is rod-shaped and can be guided along a roof gutter. At the lower end of this backrest, a sleeve and a rod with a support surface for bracing against a house wall are provided. A retaining element is articulated to the sleeve and adjustable in length at predetermined positions; this retaining element can be hooked into a roof hook. Furthermore, clamping jaws projecting from the backrest are provided, which can be slid onto the roof gutter in a horizontal direction and clamped in place. For assembly, the retaining element is first hooked into a roof hook, and the length of the retaining element and the rod are adjusted. The clamping jaws are then pressed together with a clamping screw.

[0008] JP 2013 - 23 879 A discloses a roof enclosure designed to support a flexible foil body and prevent the spread of dust, cleaning water, and similar liquids during roof work. The enclosure comprises a rod-shaped body that runs along a gutter and features adjustable pressure elements for securing it to the gutter. A rope is attached to the top of the rod-shaped element for additional support against the roof ridge.

[0009] DE 76 17 402 U discloses a safety device for securing persons against falling from tiled roofs, comprising a U-shaped flat iron hook, a link chain and a carabiner hook.

[0010] AT 399 742 B discloses a roof protection fascia with support legs resting on the roof surface. To ensure that the roof protection fascia can be securely installed even after the roof has been covered, tensile-resistant tabs are permanently attached to the rafters. For this purpose, so-called tabs are attached to the rafters using nails via additional retaining tabs, even during the initial roof construction and before the first covering is applied.

[0011] FR 2 593 542 A1 discloses a similar support frame for the arrangement on the roof surface as well as support bases for a gable railing that can be attached to the sloping edge of the roof between the ridge and the eaves.

[0012] The present disclosure relates to a safety technique which can be used particularly advantageously with a set-pile edge fall protection system or which may include a set-pile edge fall protection system.

[0013] The adjustable pile edge fall protection system according to the present disclosure can be designed in its basic structure according to WO 2003 / 093609 A1. It is intended and designed to form or support a temporary parapet on a building roof in the intended installed state. Preferably, further improvements or modifications to the adjustable pile edge fall protection system are included, in particular to the design of the adjustable piles, which are discussed below.

[0014] The adjustable post edge fall protection system according to the present invention comprises at least one frame body with at least one adjustable post, and preferably with two adjustable posts, and optionally a parapet body. Preferably, at least one downward-projecting cantilever with a wall support plate is provided on the frame body in a substantially parallel arrangement to the adjustable posts. This cantilever can be placed against a portion of the building's exterior wall located below the gutter. The cantilever is offset from the adjustable posts by a certain distance, so that in the intended installation state it extends outside the gutter provided by the building.

[0015] The adjustable post-type fall protection system can consist of a single frame that is inserted into a gutter on a building roof. This frame can serve as an attachment point for any type of guardrail. For example, a rigid external guardrail can be attached to the frame of the adjustable post-type fall protection system on one side and to a suitable existing structure on the other. Alternatively, it is also possible to attach a guardrail, at least temporarily, to only one frame, particularly if the length of the roof edge to be secured is relatively short, for example, less than 2 meters, and especially less than 1.2 meters.

[0016] The adjustable post-type fall protection system can provide immediate protection within seconds. Simply insert the frame of the system into the gutter running along the roof edge and, for example, temporarily place a batten into the railing brackets on the frame to serve as a railing. This provides immediate, ad-hoc fall protection. Users of the system experience effective protection against falls from the roof edge during all subsequent work steps, from the installation phase until shortly before dismantling, which can save lives.

[0017] The adjustable post-type fall protection system comprises at least one frame. Preferably, the adjustable post-type fall protection system comprises at least two, three, or four frame components, or an even greater number of frame components. Several frame components are to be installed side by side at the roof edge of the building, spaced apart. A fall protection device can then be arranged between each pair of adjacent frame components, or between a frame component and a suitable on-site structure, spanning the space between the frame components.

[0018] Another optional and preferred component of the adjustable post edge fall protection system is a railing element that can be attached to two adjacent frame bodies. The railing element is preferably rigid and can have a frame shape. It preferably has a plurality of struts that, in the intended mounting position, run essentially parallel to the roof edge, with each strut positioned at a different distance above the roof edge. The multiple struts preferably form a parapet that secures the height range from the roof edge down to at least the hip height of a worker. It is also possible to install two or more railing elements at different suitable heights between two adjustable frames.

[0019] The object of the present invention is to demonstrate a safety technique that improves the handling and / or the safety effect of edge fall protection systems for fixed poles.

[0020] The invention solves this problem through the features of the independent claims.

[0021] Security technology encompasses several aspects, each of which can be used individually or in combination to contribute to solving the task.

[0022] A first aspect of the present invention relates to a fall protection method for providing fall protection at the roof edge of a building roof with a preceding gutter. The fall protection method comprises at least the following steps, which can be carried out in the specified or any other order or overlapping in time.

[0023] At least one adjustable post edge fall protection system is provided and at least one adjustable post of the frame body of this adjustable post edge fall protection system is installed in the channel.

[0024] A pile base fixing device is attached to the setting pile, specifically to a base section of the setting pile. The pile base fixing device comprises at least one tensioning element, and a first end of the tensioning element is fixed to the setting pile.

[0025] A second end of the tensioning device is attached to a supporting beam of the building roof located towards the roof edge, forming an attachment point.

[0026] The tensioning device is stretched between the setting post and the attachment point on the support beam, so that the tensioning device supports the frame body of the setting post edge fall protection system against the support beam in a force-conducting manner.

[0027] The terms "first end" and "second end" are used solely to distinguish the two end regions of the tensioning device and have no numerical meaning. The first end can be a dorsal end, pointing towards the frame. The second end can be a distal end, pointing towards the building roof. The term "end" can refer to an endpoint or end section of the tensioning device, particularly in relation to its force-conducting function.

[0028] The traction element is rigid in the intended direction of tension and preferably has high tensile strength. It is flexible in at least one other direction.

[0029] Tensioning the tensioning device involves (or may exclusively involve) tightening the tensioning device to eliminate any excess length between the positioning post and the attachment point on the support beam. In other words, tensioning the tensioning device can be performed without lifting or removing the positioning post from the channel. Alternatively, the positioning post can remain in its set position within the channel during tensioning. In other words, tensioning the tensioning device occurs between the positioned positioning post and the attachment point on the support beam. Therefore, it is not necessary to additionally guide or support the positioning post or the frame during the tensioning process. Thus, the positioning of the positioning post edge fall protection system and the installation of the post base fixing device can be carried out separately.In particular, the positioning of the retaining pile edge protection system can be carried out first, followed by the installation of the pile base fixing device or at least the tensioning of the tensioning device. This prevents accidents during installation or dismantling.

[0030] The fall protection system offers several advantages. Firstly, an immediate fall protection effect is provided as soon as the positioning post is placed in the channel. All subsequent steps can be carried out by a single worker, while the post-edge fall protection system is already properly positioned and / or provides basic fall protection. Furthermore, positioning the positioning element is particularly quick and easy because no additional fasteners are required before the post is placed in the channel. The post base fixing device is adaptable to local conditions. The second end of the tensioning device can be attached and tensioned at a location that is generally freely selectable on the support beam.The tensioned tensioning device can transfer the forces occurring in the event of a fall to the supporting beam, thus relieving the gutter (at least or precisely from these forces acting in the event of a fall). In other words, the gutter can be almost or completely free of force by implementing the fall protection system, or it can only provide supplementary support. The fall protection system can therefore ensure the safety of workers or loads on the building roof regardless of the gutter's actual load-bearing capacity. It is not necessary to perform load tests or static calculations before implementing the fall protection system. Rather, it may be sufficient if the existing gutter is suitable for supporting the adjustment and positioning of the frame without impermissible deformation.

[0031] A further aspect of the present invention comprises a pile base fixing device for securing an installation pile of the frame body of an installation pile edge fall protection system to a building roof. The pile base fixing device comprises a tensioning element with a first end and a second end, wherein the pile base fixing device is configured to fix the first end of the tensioning element to an installation pile, namely to a base section of the installation pile, wherein the installation pile is adjustable or set in a groove running along the roof edge of the building roof. The pile base fixing device is further configured to attach the second end of the tensioning element to a section of a supporting beam of the building roof located towards the roof edge, such that the tensioning element can be tensioned or is tensioned and supports the frame body against the supporting beam in a force-conducting manner.

[0032] A pile base fixing device according to the present disclosure is thus designed and suitable for implementing the fall protection method for an adjustable pile edge fall protection system. The pile base fixing device can be a separate component or an integral part of an adjustable pile edge fall protection system. The tensioning element of the pile base fixing device is designed and configured to adjust, and in particular shorten, the effective length between the adjustable pile and the attachment point on the support beam to create a force-conducting support. The tensioning element is specifically designed and configured so that the adjustment of the effective length is carried out while the adjustable pile is positioned in the channel. The pile base fixing device preferably comprises a tensioning element, which is further preferably arranged on the adjustable pile or at the attachment point.

[0033] The pile foot fixing device can be positioned between the substructure of the building roof and the roof covering, in particular a roof tile, and allows for the immediate re-roofing of the building. This effectively prevents any interruption of the roof's sealing function during maintenance work.

[0034] Another aspect of the present disclosure includes the use of a pile foot fixing device according to the present disclosures for fastening an adjustable pile edge fall protection system to a supporting beam of a building roof.

[0035] Another aspect of the present disclosure relates to an adjustable pile edge fall protection system for forming a temporary fall protection barrier on a building roof with an upstream gutter. The adjustable pile edge fall protection system comprises a frame body with at least one adjustable pile that is adjustable in the gutter. The adjustable pile edge fall protection system further comprises the aforementioned pile base fixing device. It may further, in particular, comprise a plurality of frame bodies and / or a plurality of pile base fixing devices. It may also comprise at least one guardrail body.

[0036] Another aspect of the present disclosure relates to a beam fitting for attaching a tension member to a beam of a building roof. The tension member can, in particular, be a component of the pile base fixing device according to the present disclosure. The beam fitting includes an eyelet for receiving the tension member. In the intended application, a (second) end of the tension member is guided through the eyelet and at least partially wraps around an end face of the eyelet. The beam fitting includes a locking body with an end section that extends opposite the end face of the eyelet. The locking body is movable from a mounting support state to a fixing state. In the mounting support state, the end section of the locking body is spaced from the end face sufficiently to allow at least limited movement of the tension member around the end face.In the fixed position, the end section is brought so close to the front edge and pressed against the front edge that the tensioning element is fixed to the support beam fitting.

[0037] The support beam fitting according to the present disclosure offers several advantages. It can be used simply and quickly to attach the (second) end of the tensioning element to a substantially freely selectable location on a support beam to form a fastening point. When or as long as the assembly support state exists, the tensioning element can be movable relative to the support beam fitting, and in particular the eyelet, in such a limited manner that the other end (the first end) of the tensioning element can be lengthened or shortened relative to the support beam fitting. In the fixed state, the tensioning element is immovably fixed relative to the support beam fitting. The length of the other end (the first end) of the tensioning element is, in particular, infinitely adjustable.

[0038] A support beam fitting according to the present disclosure can be designed to be particularly flat, so that it can be arranged in a space between a tile and a support beam of the building roof. Thus, after the installation of the support beam fitting, the tile can be re-covered into the building roof without impairing the sealing effect.

[0039] On the other hand, the support beam fitting can be manufactured in a particularly simple and cost-effective manner and can remain on the building roof after the dismantling of an adjustable post edge fall protection system.

[0040] Starting from the support beam fitting to a load attached at the other end (at the first end) of the tensioning device, in particular an installation pile, no further components are required, so that the tensioning device can be guided particularly flat between the supporting structure of the building roof and the roof covering, and does not impede the closing of the roof covering by re-tiling. Another aspect of the present disclosure relates to a pile base fitting for forming a tensioning device attachment point on an installation pile of an installation pile edge fall protection system, in particular on a base section of the installation pile. The pile base fitting comprises a clamp body with a curved section. In the intended installation position, the curved section engages the base section of the installation pile. The curved section runs, in particular, along a side of the installation pile that is furthest from the building roof.The curved section can preferably grip the setting post in a U-shape.

[0041] A fastening structure for securing a traction element is formed on the clamp body.

[0042] According to a preferred embodiment, the pile foot fitting comprises a plug-in section designed to be inserted into an opening on the setting pile, in particular into a side opening on the foot section of the setting pile.

[0043] The pile base fitting according to the present disclosure offers several advantages. By gripping the installation pile, the potential support force that may occur in the event of a fall, acting on a tension member fixed to the fastening structure, is distributed over a surface area and supported as a compressive load on the installation pile. In this way, even very high support loads can be transferred to the installation pile, and there is no risk of local material cracking or buckling. The pile base fitting can therefore be used with any existing installation pile edge fall protection system without requiring mechanical stiffening in the base section of the installation pile or a static recalculation of the load-bearing capacity, which might be necessary, for example, when drilling or otherwise weakening the material in the base section of the installation pile.

[0044] Inserting the pile base fitting into an opening, particularly a side opening, allows for especially quick and easy installation. The plug-in section can itself be hollow, allowing rainwater flowing within the roof gutter to pass through. The plug-in section can be designed and configured to form a pipe-in-pipe connection at the base of the installation pile.

[0045] Further advantageous embodiments of the invention are disclosed in the following description and the accompanying drawings.

[0046] The invention is illustrated in the drawings in an exemplary and schematic manner. These show: Fig. 1: A post-and-rail edge fall protection system according to the present disclosure; Fig. 2: A pile foot fixing device according to the present disclosure, which force-conductingly supports an installation pile on a supporting beam of a building roof; Fig. 3: The pile foot fixing device according to Fig. 2 in a side view; Fig. 4: The pile foot fixing device according to Fig. 2 in enlarged view; Fig. 5: The pile foot fixing device according to Fig. 4 in a unique position; Fig. 6: The pile foot fixing device according to Fig. 4 in an exploded view; Fig. 7-9: A support beam fitting according to the present disclosure in two oblique views and in a half section; Fig. 10, Fig. 11: Detailed views of a clamping body; Fig. 12, Fig. 13: A pile foot fitting according to the present disclosure in two oblique views; Fig. 14, Fig. 15: An automatic carabiner suitable for one-handed operation in an open and a closed position.

[0047] In Fig. Figure 1 shows a preferred embodiment of an adjustable post-type fall protection system 100. It comprises a frame body 120 with at least one adjustable post 101 and, in particular, two adjustable posts 101, 102 arranged parallel to each other. The adjustable body 120 further comprises a boom 110 that projects downwards relative to the at least one adjustable post 101, 102. A wall support plate 111 is preferably arranged at a distal end of the boom 110.

[0048] For the sake of simplicity, it is assumed that the adjusting body 120 comprises two adjacent adjusting piles 101, 102. It is further assumed that each adjusting pile 101, 102 has a base section 103, 104, which can be inserted into the channel 202 in the intended mounting position. The two base sections 103, 104 are preferably spaced apart from each other in the direction of the channel 202 and are positioned at the same height on the frame body 120 with respect to the boom 110.

[0049] In the intended mounting position, a foot section 103, 104 extends downwards in a vertical direction as a distal end of an adjustment post 101, 102, so that it can be adjusted vertically into an upwardly open channel 202, with a vertically lowest boundary surface of the foot section 103, 104 coming into physical contact with the bottom of the channel 202. Fig. 1 The adjustment movement is sketched by arrows and the point of contact between each foot section 103,104 and the bottom of the trough 202 is illustrated by a dashed line at the arrowhead.

[0050] As an alternative to the embodiment shown in the figures, only one adjusting post 101 may be provided, and / or a different number of foot sections 103, 104 may be provided. For example, a single adjusting post with a single foot section may be present. The foot section may have a width along the course of the channel 202 that allows for adjustment secured against lateral tilting. The width may, for example, be greater than 30 cm or greater than 50 cm.

[0051] The preferred embodiment according to the illustration in the figures comprises two individual foot sections which are essentially narrow, in particular with a width along the extent of the channel 202 of less than 30 cm, in particular less than 15 cm.

[0052] The base section 103, 104 of an adjustment pile 101, 102 preferably comprises at least one opening 105, 106, in particular a side opening, which extends further, especially in the direction of the channel 202. The opening 105, 106 can be formed in any desired manner. According to a preferred embodiment, an adjustment pile 101, 102 comprises a passage body 114 at its base section 103, 104. The passage body can, in particular, be formed by a tube. The passage body is preferably designed and configured to allow liquid to pass through it along the course of the channel 202. The at least one opening 105, 106 is preferably an end opening of the passage body 114.

[0053] The at least one opening 105, 106 can preferably be used to directly or indirectly fix a pile base fixing device 1 according to the present disclosure. A particularly preferred embodiment provides that the pile base fixing device 1 comprises a pile base fitting 50 with a plug-in section 54, wherein the plug-in section 54 can be inserted into an opening 105, 106. Alternatively, a pile base fixing device 1, and in particular a (first) end of the tensioning element 40, can be fixed directly or indirectly to the setting pile 101, 102 in any other way.

[0054] The adjusting body 120 preferably comprises a channel support 113, which is movably, and in particular rotatably, arranged on the adjusting body 120. The channel support 113 is preferably designed to be pressed against an outer or underside of the channel 202 when a foot section 103, 104 is inserted into the channel 202 in order to secure the frame body 120 against being lifted out of the channel 202.

[0055] The frame body 120 may further preferably have at least one railing receptacle 112 into which a railing body of any design (not shown) can be inserted.

[0056] The adjustable post edge fall protection system 100 is particularly advantageous for use on a building roof 200, especially a pitched roof, with a forward-positioned gutter 202. The gutter 202 is arranged, in particular, in a horizontal direction in front of a roof edge 201 and, in a vertical direction, at least partially below the roof edge 201. The gutter 202 is particularly preferably a rain gutter.

[0057] The building roof 200 can have any type of construction. It comprises, in particular, a supporting structure with load-bearing beams 203, 203' and a roof covering. The roof covering can have any design. It preferably comprises a plurality of roof tiles, which can be laid in rows along the roof edge 201, overlapping and / or adjacent to one another. Furthermore, several rows of tiles 204, 205, 206 can be arranged overlapping and / or adjacent to one another, offset from the roof edge 201.

[0058] The roof covering, and in particular the roof tiles 210, can be attached to the supporting structure in any way. The most common design in practice involves the provision of battens on the supporting structure, in particular an arrangement of several roof battens running essentially parallel to the roof edge 201.

[0059] In the example shown in the figures, a supporting beam 203,203' is a rafter that extends substantially from an eaves-side end of the supporting structure to a ridge. In other words, the figures show an example of a rafter roof. However, the present disclosure is essentially independent of the construction method of the building roof. A supporting beam 203,203' can also be a purlin, i.e., a beam of the supporting structure of the building roof that runs substantially parallel to the roof edge 201. In other words, the building roof 200 can have the construction form of a purlin roof. Alternatively, any other construction forms are possible on which the securing technique according to the present disclosure can be advantageously applied.

[0060] The fall protection method according to the present disclosure provides, in a preferred embodiment, that the pile foot fixing device 1 to be used, which is intended for fixing a setting pile 101, 102 to the building roof 200, comprises a support beam fitting 10. The support beam fitting 10 can have any design. It is fixed on one side to the top beam 203 to form an attachment point 43, in particular an attachment point 43 that directly supports any tensile force acting on the top beam fitting 10 via a tensioning element 40 against the supporting structure of the building roof 200. For this purpose, the support beam fitting 10 is preferably attached to the top beam 203 with a correspondingly load-bearing fixing element 70, which is certified for the intended use. As shown in Fig. 3. The fixing device 70 is preferably used to anchor itself in the support beam 203. The fixing device 70 can have any suitable design. In the examples shown, the fixing device 70 is designed as a screw.

[0061] The support beam fitting 10, on the other hand, receives one end 42 of the tensioning element 40 of the pile base fixing device 1 in a force-supporting manner. At least when and as long as a fixing state B exists, the tensioning element 40 is immovably connected to the support beam fitting 10. The support beam fitting 10 is thus designed and configured to support any tensile force acting on the tensioning element 40 on the support beam 203 in a force-conducting manner, at least in the fixing state B.

[0062] The traction element 40 can have any desired form. For example, it can be linear or ribbon-shaped. It is preferably made of a tensile-resistant and highly tear-resistant material. Particularly preferably, the traction element 40 is formed by or comprises a webbing. Alternatively or additionally, the traction element 40 can be formed by or comprise a metal band.

[0063] Fig. Figure 2 illustrates the force-conducting support connection between an adjustable post 101 of the edge fall protection system 100 and the attachment point 43 on the support beam 203. In the figures, the edge fall protection system is shown at a considerable distance from the roof edge 201 and from a support beam 203 to allow good visibility of the various structural components. In actual use, the frame 120 will be arranged in close proximity to the roof edge 201, whereby the effective length L of the tensioning element 40 between the individual post 101 and the attachment point 43 will be significantly shorter.

[0064] In the fall protection method according to the present disclosure, it may be provided that at least one roof tile 210 of the building roof 200, which lies above an intended attachment point 43 on the support beam 203, is (temporarily) removed in order to attach the tensioning device 40 or the support beam fitting 10 to the support beam 203, 203'. In particular, it may be sufficient to remove only a single tile locally from an adjacent row of tiles, especially from the lowest row of tiles 204.

[0065] The fall protection procedure may further provide that the (removed) cover tile 210 is reinserted into the building roof 200 after the fastening of the tensioning device 40 and in particular after the establishment of the fixation state B.

[0066] The pile foot fixing device 1 according to the present disclosure can have a particularly shallow footprint in the intended mounting position. In particular, the tensioning element 40 and / or the support beam fitting 10 can have a designated bearing surface (F) on the supporting structure of the building roof 200, in particular on a support beam 203, 203', and have a height above this bearing surface (F) of less than 40 mm, in particular less than 30 mm. The width of the tensioning element 40 and / or the support beam fitting 10, which is oriented on the one hand parallel to the bearing surface (F) and on the other hand transversely to the direction of the tensile force, can preferably be selected to be at least so large that, when the nominal support load assumed in the case of securing is applied, no impermissible transverse penetration of the tensioning element into the surface of the supporting structure of the building roof 200 and / or into a contact surface of the channel 202 occurs.The width can be, for example, at least 20 mm, at least 30 mm or at least 40 mm.

[0067] The pile base fixing device, and in particular the tensioning element 40 and / or the support beam fitting 10, can preferably be designed as a single-use item. Alternatively or additionally, the tensioning element 40 and / or the support beam fitting can be designed and configured for multiple uses.

[0068] The fall protection system may be designed so that, during dismantling, at least part of the tensioning device 40 and / or the support beam fitting 10 remains attached to the building roof 200. In particular, it is possible to cut the tensioning device 40 in the area of ​​the roof edge 201. The (second) end of the tensioning device 40, fixed at the attachment point 43, can remain on the building roof 200, while the part of the tensioning device 40 protruding from under the roof membrane is removed and disposed of. In this way, the dismantling of the pile base fixing device and the entire adjustable pile edge fall protection system 100 can be carried out particularly quickly and, in particular, without the need to reopen the roof membrane. This eliminates any unsecured position of a worker on the building roof 200.In particular, all steps for the assembly and disassembly of the adjusting elements 120 and the pile base fixing device 1 can be performed while a worker is, for example, on a ladder or a lifting platform, positioned horizontally in front of the roof edge 201. As detailed below, all steps for operating the pile base fixing device can preferably be performed with one hand, allowing the worker to hold on and secure themselves with their other hand at any time during assembly and disassembly. The safety device according to this disclosure thus provides maximum support for uninterrupted fall protection throughout all phases of use.

[0069] The pile base fixing device 1 according to the present disclosure preferably comprises a tensioning device 19. The tensioning device 19 can have any shape and configuration. It is preferably configured to adjust the effective length L of the tensioning element 40 between the setting pile 101, 102 and the attachment point 43 on the support beam 203, 203' such that the tensioning element 40 is tensioned in a force-conducting manner and supports the frame body 120 in a force-conducting manner on the support beam 203, 203'. The tensioning device 19 is particularly preferably formed by the support beam fitting 10. A preferred embodiment is explained further below. Alternatively, the tensioning device 19 can be formed separately. It can preferably be arranged on the support beam fitting 10.

[0070] The pile base fixing device 1, and in particular the support beam fitting 10, is preferably designed to be moved from an assembly support state A to a fixing state B. In the assembly support state A, the tensioning element 40 is held with a clamping force that can be overcome, so that it can be tensioned between the attachment point 43 on the support beam 203 and the setting pile 101, 102 by adjusting the effective length L. In other words, the tensioning element 19 of the pile base fixing device 1, and in particular of the support beam fitting 10, allows for adjustment and, in particular, shortening of the effective length L in the assembly support state A. In the fixing state B, the tensioning element 40 is fixed at the (previously) set length L. In other words, the tensioning element 19 is in a state of restricted movement in the fixing state B.

[0071] Holding the tensioning device with an overcomeable clamping force and / or fixing the tensioning device 40 is preferably carried out by the pile base fixing device 1 and further, in particular, by the support beam fitting 10. In particular, both steps can be carried out simultaneously by the support beam fitting 10, especially by the clamping device 19. Alternatively, only either holding the tensioning device with an overcomeable clamping force or fixing the tensioning device at a set length can be carried out by the support beam fitting 10 and especially by the clamping device 19.

[0072] A preferred embodiment of a support beam fitting according to the present disclosure is described in the Fig. Figures 7-11 are shown in an enlarged view. The support beam fitting 10 is designed for attaching a tension member 40 to a support beam 203 of a building roof 200. It includes an eyelet 11 for receiving the tension member 40. A (second) end 42 of the tension member 40 can be guided through the eyelet 11, so that the tension member 40 at least partially wraps around an end face 15 of the eyelet 11. A tensile force can preferably be transferred from the tension member 40 to the support beam fitting 10 via this end face 15.

[0073] The support beam fitting 10 comprises a locking body 13. An end section 21 of the locking body 13 extends towards the front edge 15 of the eyelet 11. The locking body 13 is preferably movable and / or deformable. In particular, it can be moved from a mounting support state A to a fixing state B. Fig. Figure 9 shows an example of a transition from the assembly support state A to the fixing state B by a deformation of the bar body 13 in a cross-sectional view.

[0074] In the assembly support state A, the end section 21 of the locking body 13 is spaced from the end face 15 of the eyelet 11 such that the tensioning element 40 is guided with at least limited movement around the end face 15. The effective length L can be adjusted by moving the tensioning element 40, in particular by applying a (manual) tensile force to either the first end 41 or the second end 42 of the tensioning element 40. On the other hand, the movement is preferably guided such that the position of the tensioning element 40 relative to the support beam fitting 10 remains essentially unchanged when the (manual) tensile force is removed. Thus, the limited movement of the tensioning element ensures that a tensioned state of the tensioning element 40 is maintained in the length section between the adjusting foot 101, 102 and the fastening point 43. In particular, the traction element 40 can be held in the eyelet 11 by an overcoming clamping force.

[0075] In the fixed position B, the end section 21 of the bolt body 13 is brought so close to the end edge 15 and pressed against it that the tensioning element 40 is fixed to the support beam fitting 10. Particularly preferably, bringing the end section 21 close to the end edge 15 significantly increases the clamping force acting on the tensioning element 40 in the eyelet, making it greater than any tensile force that could be expected to act on the tensioning element 40 in the event of locking.

[0076] The locking body 13 can be designed separately. The locking body 13 can, for example, be part of a bistable clamping device that can be moved back and forth between a mounting support state A and a fixing state B.

[0077] A preferred embodiment provides that the locking bar 13 is designed such that it can only be moved into the fixing state B on one side, but cannot be moved back into the assembly support state A. For this purpose, the locking bar can in particular undergo a plastic deformation and / or a permanent stiffening and / or be permanently locked in the fixing state.

[0078] As in its preferred embodiment, the bolt body 13 is integrally connected to the support beam fitting 10. A particularly preferred manufacturing method provides that a base body of the support beam fitting 10 is formed from a sheet of metal. The eyelet 11 and / or the bolt body 13 can be formed on the base body of the support beam fitting 10 by removing material and / or by forming.

[0079] In the example according to Fig. 7-9 the support beam fitting with the eyelet 11 and in the bolt body 13 is manufactured from a sheet metal or metal plate by cutting, in particular laser cutting, and forming, in particular bending or pressing.

[0080] The traction element 40 can be guided and fixed directly between, on the one hand, the front edge 15 of the eyelet 11 and, on the other hand, the end section 21 of the bolt body 13.

[0081] A preferred embodiment provides that the support beam fitting 10 comprises a movable and preferably separately formed clamping element 12. The clamping element 12 is preferably arranged, or can be arranged, between the end edge 15 of the eyelet 11 and the end section 21 of the bolt body 13. Particularly preferably, the clamping element 12 is inserted within the eyelet 11. The tensioning element 40 can further preferably be guided either between the end edge 15 and the clamping element 12 or between the clamping element 12 and the end section 21. Fig. Figure 5 illustrates the guidance of the traction element 40 between the front edge 15 and the clamping body 12.

[0082] In Fig. Figure 7 shows an alternative form of the traction element guidance in which a length section of the traction element 40 forms a loop, wherein a first loop section lies between the clamping body 12 and the end section 21 of the locking body 13, while a second loop section lies between the locking body 13 and the end edge 15.

[0083] The clamping body 12 can have any shape. Fig. 10 and Fig. Figure 11 shows a preferred configuration of the locking body 12 in oblique front and rear views. The clamping body 12 can include a groove section 31, which is preferably oriented towards the end edge 15. The groove section 31 is preferably configured such that the tensioning element 40, in the fixed position B, is guided and clamped with a wrap angle of at least 120 degrees, preferably with a wrap angle of 180 degrees, in particular between the groove section 31 and the end edge 15. Alternatively or additionally, a groove section can be oriented towards the end section 21 of the locking body 13.

[0084] In the case of traction control according to Fig. 7 a first groove section 31 oriented towards the front edge 15 and a second groove section (not shown) oriented towards the end section 21 of the bar body 13 can be provided.

[0085] The clamping element 12 is preferably elastic. It is preferably designed to secure the fixing of the tensioning element 40 to the support beam fitting 10 with an elastic clamping force in the fixing state B.

[0086] The clamping element 12 can be mounted on the support beam fitting 10 in any desired manner. A preferred embodiment provides that the clamping element 12 is movably guided on the support beam fitting 10, in particular translationally, especially via a collar guide. More preferably, one element from the group consisting of the support beam fitting 10 and the clamping element 12 can have a guide collar 17, and the other element can have an engagement section 30 that slides onto the guide collar 17. In the example of Fig. 7-9 The guide collar 17 is formed by a downwardly bent tab of the base body of the clamping body 13. An engagement section 30 is formed on the clamping body 12 by a recess, which is located in particular transversely to the groove section 31.

[0087] The clamping body 12 can be arranged according to the illustration in Fig. 11 have a receiving section 32, which is provided in particular opposite a (single) groove section 31. The receiving section 32 is further preferably oriented towards the end section 21 of the bolt body 13. During the transition of the bolt body 13 from the assembly support state A to the fixing state B, the end section 21 of the bolt body 13 can preferably be inserted at least partially into the receiving section 32 and secured against slippage. The receiving section 32 can be formed in any way, in particular by a surface recess.

[0088] Fig. 12 and Fig. Figure 13 illustrates a preferred embodiment of a pile base fitting for forming a tension member attachment point on a pile 101, 102. The pile base fitting 50 comprises a prong body 51 with a curved section 53. In the intended mounting position, the curved section engages a foot section 103, 104 of a pile 101, 102 of a pile edge fall protection system 100. Preferably, a fastening structure 52 for securing a tension member 40 is formed on the prong body 51. The fastening structure 52 can have any configuration. In particular, it can be designed as an opening with an edge 55 limiting it in the direction of tension. The fastening structure 52 is preferably provided at one end of the curved section 53, so that a force transmission from the fastening structure 52 can take place directly via the curved section 53 to a side of the setting post 101 facing away from the roof edge 201.The curved section preferably has a planar form. Particularly preferably, the clamping body 51 with the curved section 53 and the fastening structure 52 is formed in one piece from a tensile-resistant body, for example from a metal sheet or a composite material, in particular a fiber-reinforced plastic.

[0089] The pile base fitting 50 may further preferably comprise a plug-in section 54, which is designed to be inserted into an opening 105, 106 on the setting pile 101, 102, in particular into a side opening on the base section 103, 104 of the setting pile 101, 102. The plug-in section 54 is preferably offset vertically in the intended mounting position relative to the clamp body 51 and in particular to the curved section 53.

[0090] In other words, the clamp body 51 is preferably designed such that the fastening structure 52, and preferably also the curved section 53, is offset upwards in the intended mounting position by a distance K in the vertical direction relative to the bearing surface of the setting pile 101, 102. The distance K is given by way of example in Fig. 2 shown.

[0091] The distance K ensures that, in the event of a fall, the force is applied via the tensioning element 40 at a height just above the gutter 202, and particularly at a height between the gutter 202 and the roof edge 201. This results in a particularly safe and effective form of force application. Specifically, the support force can be transferred to the positioning post 101, 102 at an angle between 70° and 90°, preferably between 80° and 90°. This prevents the positioning post-edge fall protection system 100 from moving impermissibly in the event of a fall. In particular, lifting in response to the application of the securing force is avoided, and damage to the gutter 202 can be reduced or eliminated. The distance K can be chosen to be suitable. A preferred embodiment provides that the distance K is adjustable.The spacing can be at least 5 cm, preferably at least 8 cm. In an exemplary embodiment, the spacing K is 12 cm.

[0092] The pile base fitting 50 and the (first) end 41 of the traction element 40 can be connected to each other in any way. A preferred embodiment provides that the pile base fixing device 1, and in particular the pile base fitting 50, comprises a releasable fastening element 60, which is designed to fix a (first) end 41 of the traction element 40 to the pile base fitting 50, in particular a carabiner.

[0093] Fig. Figures 2-6 show an example of a carabiner 60 comprising a substantially D- or egg-shaped base body, at the rounded ends of which the intended force is applied, wherein an opening mechanism with a locking device 61 is provided at an intermediate section.

[0094] A preferred embodiment provides that the pile base fixing device, in particular the carabiner 60 and / or the pile base fitting 50, comprises an alignment means 72. The alignment means 72 is preferably designed and configured to orient the carabiner 60 in the expected direction of force flow in the intended assembly state. This facilitates and simplifies the connection between a (first) end 41 of the traction element 40 and the carabiner 60.

[0095] A preferred embodiment provides that the releasable fastening element 60 or the carabiner is an automatic carabiner 60' with a release mechanism 64 designed to cause the automatic carabiner 60' to automatically transition from an open state I to a closed state II when an external body 68 is inserted into the muzzle area 67 of the automatic carabiner 60'. The external body 68 can, in particular, be a fastening structure at the end 41 of the towing element 40 and / or a fastening structure 52 on the post base fitting 50.

[0096] Fig. 14 and Fig. Figure 15 illustrates a preferred embodiment of an automatic carabiner 60'. In the example shown, the external body 68 can be the rim 55 on an opening 52 of the post-foot fitting 50. Alternatively, the external body 68 can, for example, be an eyelet body 45 provided at the (first) end 41 of the drawbar 40.

[0097] In the example shown, the automatic carabiner comprises a housing with a muzzle area 67. A first hook element 62 and a second hook element 63 are rotatably mounted on the housing. Each of the hook elements 62, 63 comprises a leg 65, 66 which, in the open state I, lies within the muzzle area 67 and forms an obstruction for the insertion of the external body 68. When the external body 68 is guided against these legs 65, 66, the distal ends of the hook elements 62, 63 move into a closing position in which they overlap the muzzle area 67. Simultaneously, they force the external body 68 toward the center of the muzzle area 67, where it is physically enclosed between the housing and the two hook elements 62, 63.

[0098] Each of the hook elements 62, 63 can include a lever 69 by means of which a manual return movement from the closed state II to the open state I can be effected. Preferably, the automatic carabiner 60' includes an additional actuation safety device that must be operated before or in parallel with the movement of the levers 69 in order to prevent accidental opening.

[0099] In the example of Fig. 14 and Fig. 15 A fastening structure 73 is provided on the housing of the automatic carabiner 60'. The automatic carabiner 60' is preferably pivotally connected to a stake base fitting 50 via this fastening structure 73. Furthermore, the alignment means 72 is preferably arranged or can be arranged in the area of ​​the connection point between the automatic carabiner 60' and the stake base fitting 50. The alignment means 72 can be formed, in particular, by an elastic body, and more specifically, by a spring. The alignment means 72 can preferably be supported on one side by a support edge 56 on the stake base fitting 50, in particular on the edge 55 of the opening 52, and on the other side by a suitable housing section of the automatic carabiner 60', in particular on a housing shoulder 74. Preferably the carabiner 60, in particular the automatic carabiner 60', is articulated on the post base fitting 60, in particular tiltable or pivotable.The range of motion of the carabiner 60, in particular of the automatic carabiner 60', is preferably limited, for example by the alignment means 72 to a preferred alignment with a surrounding tolerance range.

[0100] The pile base fixing device according to the present disclosure preferably comprises at least one support beam fitting 10 as described above and / or one pile base fitting 50 as described above. The pile base fixing device preferably comprises a releasable fastening element 60 for establishing the load-bearing connection between the (first) end 41 of the tensioning element 40 and the setting pile 101, 102. This may in particular be a carabiner 60, and more specifically an automatic carabiner 60' as described above.

[0101] Particularly preferably, the releasable fastening element 60 is designed to be opened for disassembly of the pile base fixing device 1 while the tensioning element 40 is under tension. Furthermore preferably, opening of the releasable fastening element 60 is supported without increasing the effective length L of the tensioning element 40 or changing the position of the setting pile 101, 102. This facilitates or enables one-handed operation of the pile base fixing device, even during disassembly.

[0102] A particularly preferred embodiment provides that the pile foot fixing device has (entirely) one-handed operation. This one-handed operation may include, in particular: One-handed fastening of the pile base fitting 50 to the single pile 101, 102. This can be achieved, in particular, by inserting the pile base fitting 50 into a side opening 105 on a passage body 114 of the setting pile 101, 102. After or during insertion, the pile base fitting 50 can be positioned such that the curved section 53 is in contact with the setting pile 101, 102.

[0103] Alternatively or additionally, the first end 41 of the towing device 40 can be secured one-handed to the setting post 101, 102, in particular to the post base fitting 50, and further, in particular, to the automatic carabiner 60'. The automatic carabiner 60' can be oriented either with its muzzle 67 towards the post base fitting 50 or, conversely, towards the first end 41 of the towing device 40.

[0104] Alternatively or additionally, the support beam fitting 10 can be attached to the support beam 203 by one hand to create the attachment point 43. For this purpose, the support beam fitting 10 can be placed at a suitable point on the support beam 203; simultaneously or subsequently, the fixing device 70 can be anchored in the support beam 203.

[0105] A first preferred embodiment of the support beam fitting 10 provides that the fixing means 70, in particular a screw, is pre-positioned and guided at a fastening point 14 of the support beam fitting 10. The fastening point 14 can, in particular, be an opening in the base body of the support beam fitting 10. The pre-positioning and / or guidance can be provided by a suitable guide structure 24 between the support beam fitting 10 and the fixing means 70, in particular by the one described in Fig. 9 exemplary outlines of the leadership alliance.

[0106] Furthermore, the support beam fitting 10 may preferably have an adhesive element 18 with which the support beam fitting 10 can be adhesively fastened to the support beam 203 for pre-assembly. The adhesive element 18 may, for example, be a Fig. 8 illustrated adhesive tape. Alternatively or additionally, an adhesive 18 can be provided by an impact element projecting towards the surface of the supporting beam, for example a nail or a pointed tab.

[0107] Alternatively or additionally, the clamping device 19 can be operated with one hand to tension the tensioning device 40, in particular to adjust the free length L of the tensioning device 40 with one hand. The free length L is preferably adjusted by manually pulling on the (second) end 42 of the tensioning device 40 in a section distal to the eyelet 11. In this way, the clamping force that can be overcome by the clamping device 19 can be exceeded. The tightening is preferably continued until the tensioning device 40 is taut in its direct extension between the adjusting post 101 and the attachment point 43.

[0108] Alternatively or additionally, the fixing state B can be produced by one hand. Particularly preferably, the bolt body on the support beam fitting 10 can be deformed, stiffened, or moved by one hand.

[0109] In the illustration according to Fig. 3, Fig. 5 and Fig.Figure 9 provides an example of how a further fixing means 71 can be used to deform the bar body 13 and to provide additional fixation of the support beam fitting 10 to the support beam 203. In the example shown, the bar body has a multi-part structure. The (free) end section 21 is arranged at one end of an arc body 20, while the other end section is connected to a connection point 22 with the base body of the support beam fitting 10. A fixing means opening 23 is provided in a central region of the arc body 20, at which, optionally, a guide structure 24 for the further fixing means 71 can be provided, as explained above. When the fixing means 71 is anchored in the support beam 203, the arc body 20 is deformed in the direction of a shallower curvature. This brings the end section 21 of the bolt body 13 closer to the front edge 15 of the eyelet 11.The deformation of the arc body 20 results in a supporting force that presses the end section 21 against the front edge 15 and compresses and clamps the clamping body 12 and the tensioning element 40 that may be arranged between them.

[0110] Simultaneously, the arch body 20 stiffens as a result of the reduction in the radius of curvature. Alternatively, such stiffening can be achieved separately from the deformation in another way.

[0111] Alternatively or additionally, the releasable fastening device 60, in particular the carabiner or automatic carabiner 60', can be opened with one hand to relieve and / or dismantle the pile foot fixing device 1.

[0112] Various modifications of the invention are possible. In particular, all design features and operating options of the pile base fixing device 1 can be incorporated into the fall protection method. On the other hand, all structural elements of the pile base fixing device, the adjustable pile edge fall protection system, the support beam fitting, and the pile base fitting are preferably designed and configured to support or execute one or more steps of the fall protection method.
