Description

[0001] Support connector for a scaffolding system, an arrangement containing the support connector and a method for constructing such a scaffolding system

[0002] The present disclosure relates to a support connector for a scaffolding system, an assembly containing the support connector and a method for constructing such a scaffolding system.

[0003] In construction, particularly during the construction or restoration of high-rise buildings, a scaffolding system that is no longer based on the ground but can be attached to already constructed parts of the building is extremely advantageous. A so-called climbing scaffold can be gradually pushed up the building. Rails glide up the building on climbing shoes mounted on the building. Formwork can be attached to such rails, for example, in order to construct the building, particularly a building core, and in particular to pour concrete. A climbing scaffold can, for example, also have an enclosure. In the so-called skeleton construction method - in which a facade encloses the core only towards the end of construction work - an enclosure in the form of a so-called enclosure is advantageous. The building core can have floors, ceilings, connecting elements such as stairs or elevator shafts, and other elements made of concrete, for example.The enclosure may include panels, floors, mounting rails, and other elements. The enclosure protects workers and the structure under construction or restoration from environmental influences, on the one hand, and the surrounding area and the public from falling objects, on the other. It is usually removed after completion of the construction or renovation work.

[0004] EP2956600A1 discloses such an enclosure with multiple levels, which is attached to a climbing frame. St. Andrew's crosses are used to attach the enclosure to the climbing rails. In order to withstand the considerable forces to which enclosures can be subjected, the St. Andrew's crosses in this case have a certain height. This height is further supplemented by a structure for a walkway and the walkway itself, which allows this arrangement to protrude into the area of ​​the level below. This can obstruct workers on this level below. The object of the invention is to provide a stable support connector with a low height for connecting two rails, e.g., a climbing rail and a mounting rail.

[0005] The task is solved by a support connector for connecting two vertically arranged rails for a scaffolding system comprising

[0006] - at least one connecting section extending from a first end in a first horizontal direction and having a fastening device at this first end,

[0007] - at least one spacer extending from the connecting portion in a vertical direction, wherein the connecting portion and the spacer delimit a receiving space for at least one carrier.

[0008] The connecting section, together with the spacer, defines the support space for the girder. This allows the girder, which can be positioned horizontally next to the spacer and on or below the connecting section, to be integrated into the overall height of the support connector. This reduces the risk of the girder tipping over once installed and keeps the overall height of the support connector low. The support connector therefore protrudes less into the area of ​​the scaffolding system's lower level.

[0009] The directions “vertical” and “horizontal” refer to the scaffolding system in use when it is erected on a building.

[0010] The rails can be designed as double rails consisting of two I-, L-, or U-profiles. The rails can be designed as double rails consisting of two I-, L-, or U-profiles, whose sections with the greatest extension direction are parallel to each other and held together by spacer bolts at intervals relative to their greatest extension direction.

[0011] The rails can be climbing rails and thus part of a climbing frame. The climbing rails can be held by a climbing shoe and moved up or down the structure using a structure, such as a hydraulic one. The climbing shoe can be mounted on existing parts of the structure, for example, on a vertical section such as a wall or a horizontal section such as a building ceiling.

[0012] The rails can be fastening rails and thus part of an enclosure. The enclosure can be used, for example, to protect workers or their equipment from environmental influences. Furthermore, the enclosure can reduce the risk of workers or objects falling. The enclosure can include bracket panels, floors, grab handles, protective screens, and similar components. It can consist of one or more assembled panels.

[0013] The rails may have openings to accommodate fastening elements.

[0014] The rails can be mounted on brackets. Additional components, such as panels, shelves, mounting rails, protective screens, or other components, can be attached to the brackets.

[0015] The carrier can have a longitudinal direction as the main extension direction.

[0016] The mounting location can be configured for a height and a width of the carrier.

[0017] The height of the support can be many times its width.

[0018] The support can be suitable for supporting walkways. The support connector can preferably be made of metal, in particular steel or aluminum.

[0019] Preferably, the connecting portion may have a second fastening device at a further end which is opposite the first end.

[0020] Each of the fastening devices may have openings for receiving fasteners. A fastener may be a screw, bolt, rivet, nail, dowel, or similar. Furthermore, the fastener may be additionally secured with a counterpart, such as a screw nut or a cotter pin.

[0021] The fastening device can fasten the support connector to one of the rails by means of at least one fastening element, wherein the fastening element can be received in one of the openings of the rail and simultaneously in one of the openings of the fastening device.

[0022] The support connector can be attached to one of the rails in a hinged manner. The fastening element can act as a pivot axis.

[0023] Preferably, the connecting section can have a running floor support. A running floor can be mounted on the running floor support. The running floor support can have openings for fastening the running floor. The running floor can be attached to the running floor support using screws, nails, rivets, or other connecting parts. The running floor can be made of wood, metal, plastic, or other materials. The running floor can be a single piece or composed of several floor elements arranged side by side or one above the other. A floor element can be a plate or other flat component.

[0024] Preferably, the support connector cannot exceed a total height of 100 cm, in particular 50 cm, in particular 44 cm. This ensures that the support connector is high enough to accommodate a beam and low enough not to protrude too far into the area of ​​the floor below.

[0025] Preferably, the walkway support can have an extension in a second horizontal direction, which is orthogonal to the first horizontal direction, that is greater than the extension of the spacer in the same direction. This allows the walkway support to rest on the walkway support and be securely fastened. The low material thickness of the spacer allows weight savings, thus limiting the overall weight of the scaffolding system.

[0026] Preferably, the support connector can have two mounting locations. Using two supports increases the stability of the structure. The walkway can be mounted on two parallel supports, allowing the loads to be evenly distributed and the walkway to be firmly mounted. The walkway can be attached to the support using screws, nails, rivets, or other connecting components.

[0027] The support connector can have three, four, five, six or more mounting positions.

[0028] Preferably, the spacer can have a substantially rectangular contour. As a result, one side of the rectangular contour forms a positive fit with the connecting section. On two additional, opposite sides, the spacer can provide support surfaces for a beam each. This can significantly reduce the risk of the beam tipping over. On another side of the rectangular contour, the spacer can have a contact surface.

[0029] Preferably, the support connector may comprise a second connecting portion.

[0030] The second connecting section can extend from a first end in the first horizontal direction and have a further fastening device at this first end. Preferably, the second connecting section can be spaced apart from the first connecting section in the horizontal direction. In particular, the second connecting section can have a longitudinal axis extending substantially along the first horizontal direction, which is substantially parallel to a longitudinal axis extending substantially along the first horizontal direction and on which the first connecting section lies.

[0031] Preferably, the second connecting section can have a further fastening device at a further end, which is opposite the first end. This can increase the stability of the support connector.

[0032] In other words, the support connector may comprise a second connecting portion having fastening devices at both ends thereof.

[0033] Preferably, the second connecting section can have a U-profile. The U-profile increases the stability of the support connector, saves material, and can be attached to one of the double rails on both sides, at each end.

[0034] The second connecting section can also be positively connected to the contact surface of the spacer or be integrally connected to the spacer.

[0035] In a first embodiment, the support connector may have an edge region. The edge region may be arranged between the first fastening device of the first and second connecting sections. The edge region may have a concave shape. Due to the concave shape, the support connector can be attached to the double rail regardless of spacer bolts.

[0036] Preferably, the edge area can delimit the receiving area. The edge area can have a straight side facing the receiving area and is suitable for supporting the carrier. The risk of the carrier tipping over can thus be reduced. The carrier can thus be separated from the

[0037] support area and from the other side by the spacer.

[0038] Preferably, the carrier can be designed to be axially symmetrical and have two edge regions, two receiving locations, and two fastening regions each of the first and second connecting sections.

[0039] In the first embodiment, the support connector can be formed in one piece. This increases its stability and allows it to transmit greater forces.

[0040] Preferably, the receiving space can be defined by a support support. The support support can have a surface for receiving a support. The support support improves the attachment of the support. Preferably, the support support can be height-adjustable. This allows it to be adapted to different heights of different supports. This adaptability not only allows different support types to be accommodated by the support connector, but also allows the support to be fixed between the support support and the first connecting section with greater stability against tilting.

[0041] In a first embodiment of the first embodiment, the height of the support support can be adjusted in steps. The spacer and the edge region can have perforated plates with a plurality of opposing openings extending vertically for receiving fasteners, such as screws, bolts, dowels, or pins. In this case, the support support can have corresponding openings.

[0042] Using fasteners such as screws, bolts, dowels, or pins, the support support can now be fixed in various vertically extending positions. This allows the height to be adjusted for different supports. In a second embodiment of the first version, the height of the support support can also be continuously adjusted. This allows the size of the support space to be flexibly varied and better compensates for any deformation of the supports due to environmental influences such as humidity or temperature.

[0043] Preferably, the support support can be height-adjustable by means of a threaded spindle and / or a nut.

[0044] For this purpose, a retaining nut can preferably be fixed in an area of ​​the mounting location. The retaining nut can accommodate the threaded spindle, which is connected to the support support at one end. For improved fixation, a lock nut can be attached to the threaded spindle. The height can be adjusted by turning the threaded spindle in the retaining nut.

[0045] In a third embodiment, a holding spindle can preferably be fixed in the area of ​​the receiving location. The holding spindle can accommodate a nut that is connected to the support support. For improved fixation, a lock nut can be attached to the threaded spindle. The height can be adjusted by rotating the nut around the holding spindle.

[0046] In a second embodiment, the spacer can be designed as a separate unit for attachment to the first connecting section.

[0047] The spacer may have a spacer saddle. The spacer saddle may have a U-shaped profile. The spacer saddle may be used to secure the spacer to the connecting section.

[0048] A metal strip can be arranged on the spacer saddle. The metal strip can have a rectangular contour with the spacer saddle, enclosing the edge. The metal strip can be bent at essentially right angles at two points and connected to the spacer saddle at its ends. The metal strip can be connected to the U-profile at other points using additional metal strips. The connections can be welded, for example. This makes the support connector more flexible and lighter, allowing it to be used for smaller projects.

[0049] In another embodiment, a tube or a solid form, each with a rectangular contour, can be used instead of the metal strip.

[0050] The object is further achieved by a scaffolding system comprising at least one support connector with at least one receiving location and at least one beam arranged in the receiving location.

[0051] The support connector extends substantially in a horizontal and a vertical direction. The beam extends substantially in a second horizontal direction orthogonal to the first horizontal direction.

[0052] Preferably, the carrier can be delimited by a carrier support, a spacer, a support region and a region of a connecting section.

[0053] Preferably the support can be made of wood.

[0054] Beams can preferably be made of metal, wood, plastic, or other materials. Beams can have an H-profile or be constructed from squared timber, pipes, or similar materials. In particular, the beams can have an upper chord, a lower chord, and a web connecting the upper and lower chords.

[0055] Preferably, the support connector may be arranged substantially horizontally and connect a pair of vertically arranged rails.

[0056] Preferably, the scaffolding system may comprise additional horizontally arranged support connectors that connect either the pair of vertically arranged rails or additional pairs of vertically arranged rails. A scaffolding system may, for example, comprise four double rails. Two of the

[0057] Double rails can span a single plane in which, for example, bracket panels can be arranged. The two planes can be parallel to each other and connected by two or four support connectors on the double rails.

[0058] The scaffolding system can preferably have a walkway. A walkway can be used to accommodate workers, tools, machines, or the like. The walkway can preferably be attached to one of the support connectors. The walkway can be made of wood, metal, or plastic. In particular, a walkway can be formed from one or more boards.

[0059] Preferably, the scaffolding system may include a cantilevered walkway. The cantilevered walkway may be connected to the walkway and mounted on supports that protrude from the scaffolding system.

[0060] The problem is further solved by a method for assembling a scaffolding system, which comprises the following steps in any order

[0061] - Connecting two vertically arranged rails with a support connector,

[0062] - Attaching a walking floor to the support connector and

[0063] - Inserting or placing a beam into the support connector or placing a beam onto the support connector.

[0064] The advantage is that the scaffolding system can be transported in individual parts.

[0065] Partial assembly can also be carried out before transport and the final assembly can only take place on site.

[0066] The scaffolding system can be, for example, a climbing frame or a scaffold for an enclosure.

[0067] The rails can be climbing rails and thus part of the climbing frame.

[0068] Climbing rails can be held by a climbing shoe and moved up or down the structure using a structure, such as a hydraulic one. The climbing shoe can be mounted on existing parts of the structure.

[0069] The rails can be used as mounting rails and thus as part of a bracket plate. The bracket plate can be used, for example, to protect workers or their equipment from environmental influences. Furthermore, the bracket plate can reduce the risk of workers or tools falling.

[0070] Preferably, the walkway can be secured before inserting the support beam. This allows the scaffolding system to be transported in a folded or collapsed, i.e., narrower, state.

[0071] A transport width of less than 350 cm, in particular less than 300 cm or in particular less than 250 cm, can advantageously meet the requirements of national road traffic regulations.

[0072] Preferably, the beams, which have a greater overall length than the scaffolding system in transport mode, can only be pushed or placed into the support positions at the site of use, e.g., a construction site. A cantilever deck can then be attached to the beams, while they are mounted on the scaffolding system, on the pre-assembled walkways.

[0073] The cantilever deck can also be attached to the girders without walkways. The cantilever deck can be attached to a section of the girder that extends beyond the transport width of the scaffolding system. The cantilever deck can be connected to the girders using the aforementioned fasteners.

[0074] By unfolding or unfolding the scaffolding system, the width of the scaffolding system can be significantly increased. After assembly, the scaffolding system, climbing frame, or enclosure can be erected. This means that the rails are aligned vertically, e.g., using a crane, and attached to the building using climbing shoes, as described above.

[0093] Fig. 1 shows the state of the art. Two rails 18, or

[0094] Double rails 18 are connected by an upper and a lower cross brace 20. To ensure the rails maintain the required distance from each other, they are additionally connected with a diagonal brace 31. All of the aforementioned connections are generally made with screws and nuts. Two supports 13, which can only be seen in cross-section here, are screwed onto the upper cross brace 20. A walkway 16 is mounted on the supports 13, which extend into the image plane. With a hole spacing of, for example, 37.5 cm, it is easy to calculate that the total height is over one meter.

[0095] Fig. 2 shows a support connector in a first configuration of the first embodiment. The support connector 1 has at least one connecting section 2 which extends from a first end 3 in a first direction and has a fastening device 4 at this first end 3. The support connector 1 has a further fastening device 22 at an opposite, further end 21 which is spaced from the first end 3 along the first horizontal direction. In the fastening devices, bolts 23 with spring pins 24 are shown, which can be easily inserted into the openings of a rail 18. The bolts 23 and spring pins 24 are shown only in the fastening device 22. Of course, such bolts and spring extenders can also be used for the first fastening device 4. In this way, the rails 18 and the support connector 1 can be connected quickly and securely.A spacer 5 extends from the connecting section 2 in a second direction orthogonal to the first direction, here downward. The connecting section 2 and the spacer 5 define a receiving space 6 for at least one carrier 13, which is not shown here.

[0096] The connecting section 2 faces the receiving location 6 on one side and has a running floor support 7 on the other side. The running floor support 7 has an extension in a third direction, which is orthogonal to the first two directions and is greater than the extension of the spacer 5 in the same direction.

[0097] The spacer 5 is designed here, for example, as a metal plate. The spacer 5 has two openings 25 through which additional rods (not shown here), such as longitudinal tubes or squared timbers, can be inserted and attached. These additional rods can be used, for example, to suspend nets, pulleys, or other machines or tools.

[0098] Furthermore, the spacer 5 has two square openings 26 (not shown here) through which small transport supports, such as squared timbers, can be inserted. For easier transport, an assembly floor or a walkway made of individual boards arranged next to one another in the first horizontal direction can advantageously be mounted on the transport supports. An additional walkway can be arranged on the assembly floor during assembly of the scaffolding system on the construction site.

[0099] In the example shown, the support connector 1 has two receiving locations 6. The receiving locations 6 are arranged on two opposite sides of the spacer 5. The spacer 5 has a substantially rectangular contour. At all

[0100] The spacer 5 is enclosed on both sides. It rests against the first connecting section 2.

[0101] The support connector 1 comprises a second connecting section 8 having a U-profile. The second connecting section 8 extends from a first end 27 in the first direction and has a further fastening device 28 at this first end 27. At its second end 29, the connecting section 8 has a further fastening device 30. The second connecting section is arranged at a distance from the first connecting section along the second direction and has a longitudinal axis extending in the first direction, which is parallel to a longitudinal axis of extension of the first connecting section extending in the first direction.

[0102] The U-profile can be attached to one of the double rails 18 on each side at each end 27, 29 by means of the fastening devices 28, 30.

[0103] The spacer 5 rests on the second connecting section 8.

[0104] The support connector 1 has an edge area 9 which laterally limits the receiving space 6.

[0105] The support connector 1 is constructed in one piece. All parts can be welded together, for example. This means that the two connecting sections 2, 8, with their fastening devices 4, 22, 28, 30, and the edge regions 9, are welded to the spacer 6. The support connector 1 can therefore only be disassembled into individual parts with considerable effort. The support connector 1 has a support support 10. The support 13 is placed on this support support 10. The support support 10 is height-adjustable to accommodate supports 13 of different sizes.

[0106] In the first configuration of the first exemplary embodiment, perforated plates 32, each with opposing openings 33, rest on the edge region 9 and the spacer 6. The openings 33 are suitable for receiving fastening elements 34. The support support 10 rests on the fastening elements 34. The openings 33 allow the support support 10 to be adjusted to different heights of the support 13.

[0107] In the second embodiment of the first exemplary embodiment, as shown in Figs. 3, 4, 5 and 6, the support support 10 can be continuously adjusted to different heights by means of a spindle 11 and / or a nut 12.

[0108] The threaded spindle 11 supports the support support 10 and can be rotated more or less far out of the retaining nut 12. The retaining nut 12 is firmly connected to the edge region 9, the spacer 5, and / or the second connecting section 8. In this case, the support support 10 is a round plate. Fig. 5 shows the support 13 held by the adjusted threaded spindle 11 at the bottom, the first connecting section 2 at the top, and on both sides by the edge region 9 and spacer 5, or the perforated plates 32 attached thereto.

[0109] In the third embodiment of the first exemplary embodiment, the threaded spindle 11 is designed as a fixed holding spindle 11 that is firmly connected to the edge region 9, the spacer 5 and / or the second connecting section 8. The round support support 10 is connected to a nut 12 that can move on the holding spindle 11. By moving the nut 12 on the holding spindle 11, the height for each support can be adjusted individually. Fig. 6 shows an example of an arrangement 15 of the first embodiment. The arrangement 15 has a support connector 1 with two receiving locations 6. A support 13 is arranged in each of the receiving locations 6. The respective support 13 is enclosed here by the support support 10, the spacer 5, the edge region 14 and a connecting section 2.

[0110] The support connector is secured to the rails 18 with one bolt each using the fastening devices 4, 22, 28, and 30. The fastening devices 4, 22, 28, and 30, which are mounted on the same rail 18, are spaced apart at a distance that almost corresponds to the total height of the support connector 1.

[0111] As already explained, in the present example, the support 13 is held in place by the continuously adjustable height of the support support 10. A walkway 16 is mounted on the support 13 and the support connector 1. It can be attached to the support 13 or the support connector using various fastening elements, such as screws, nails, rivets, or bolts.

[0112] In the illustrated arrangement 5, the support connector 1 also has a bracket 35 for additional rods 36. These rods 35 can be used, for example, to suspend nets, pulleys, or other machines or tools. However, the rods 35 can also serve as additional reinforcement for the scaffolding system.

[0113] The support 1 3 here is a support 1 3 made of wood with an H-profile.

[0114] The arrangement 15 also has a running floor 16. The running floor 16 is also made of wood. The wooden running floor 16 is simply nailed or screwed to the support 13.

[0115] Fig. 7 shows a second embodiment. The spacer 5 is provided as a separate

[0116] Unit designed to be attached to the first connecting section 2. The

[0117] Spacer 5 can be bent from a metal strip that defines a rectangular shape. It also has a spacer profile 37 that occupies one side of the rectangular shape and has a U-shaped profile. The metal strip can be connected to the U-shaped profile at other points, here in the center, by means of an additional metal support 38. The connections to the U-shaped profile can be welded, for example.

[0118] In an arrangement of the second embodiment, the running floor 16 is fixed to the spacer. The receiving locations 6 for the supports 13 are enclosed here by the running floor, the first connecting section 2 of the support connector 1, and the rails 18.

[0119] With the fastening devices 4, 22, 28, and 30, the support connector is fixed to the rails 18 with a bolt, as above. When mounted on the same rail 18, the fastening devices 4, 22, 28, and 30 are positioned much closer together than in the arrangement of the first embodiment. The support connector 1 has a recess on both sides, which allows space for a connecting strut for each of the respective rails.

[0120] Fig. 8 shows a section of a scaffolding system 1 7 in a side view.

[0121] Two support connectors 1 with walkways are arranged between and attached to two rails 18. The distance between the support connectors 1 is high enough so that a worker of average height can comfortably walk between them when the scaffolding system 17 is erected, i.e., the rails 18 are aligned vertically.

[0122] Fig. 9 shows the fully assembled, unfolded and ready-to-use scaffolding system 17. The scaffolding system is erected vertically and the cantilever decks 40 are terminated on both sides with the bracket discs 39, with the walkways 16 in between.

[0123] Figs. 10 to 18 illustrate the assembly process of the scaffolding system, e.g., on a construction site. The scaffolding system 17 is delivered folded, as shown in Fig. 10. The support connectors 1 are attached to the rails 18, which are covered here by the bracket discs 39. The walkways 16 are also attached to the support connectors 1.

[0124] As shown in Figs. 11 and 12, the supports 13 are first inserted into the designated receiving positions 6. The first support 13 is already inserted and the second is already located in front of its receiving position 6. The supports 13 are each pushed through a first and at least one second support connector 1 and then fastened there.

[0125] In Fig. 12, the walkway 16 and the cantilever floor 40 are only indicated by dashed lines so that the support connectors 1 and the beams 13 below can be seen.

[0126] In Fig. 13, two beams 13 are inserted into two support connectors 1 each. In Fig. 14, a cantilever floor 40 is provided to extend the work surface.

[0127] Figs. 15 and 16 show the arrangement during assembly shortly after the supports 13 have been inserted. The receiving locations 6 are large enough, thanks to the screwed-back support surfaces 10, to comfortably insert the supports 13. In Fig. 16, the support surface 10 has already been adjusted to the height of the support 13. The support 13 is thus held and is located close to the pre-assembled running floor 16. This allows the running floor 16 to rest on the support and is also suitable for carrying loads.

[0128] In Fig. 1 7, the provided cantilever floor 40 is mounted on the supports 1 3, e.g. screwed, nailed or otherwise fastened.

[0129] In Fig. 18, the previously folded bracket discs 39 have been unfolded, as already shown in Fig. 9. After aligning the rails 18 in the vertical direction, the scaffolding system 17 is now ready for use.
