Description

The invention relates to a connector for a modular framework and a modular framework with such a connector. Furthermore, a method for producing a modular framework using a connector according to the invention and the use of a connector according to the invention in a modular framework are proposed.

Technical background

A modular scaffold includes prefabricated, standardized scaffolding components that enable the scaffolding to be erected and dismantled quickly, for example to scaffold a building facade. The scaffolding components are connected using standardized connecting elements and/or connection nodes, which enable connections from different spatial directions. The scaffolding components can thus be put together to form complex planar or spatial scaffolding.

The utility model specification DE 20 2018 106 709 U1 is an example of a scaffolding node for connecting scaffolding elements running in different spatial directions, which includes a connecting tube for connection to at least one vertical standard and a connecting disk for connection to other scaffolding elements, such as horizontal bars or diagonal braces. The connecting tube of the scaffold node has a circular cross-section, the outside diameter of which is adapted to the inside diameter of the vertical post, so that the vertical post can be slipped onto the connecting tube.

Depending on the load case or requirements for the load-bearing capacity of a modular scaffold, the tube inside and/or tube outside diameter of the scaffolding components, in particular the vertical standards, can differ. The vertical standards of heavy-duty scaffolding usually have larger diameters than the vertical standards of scaffolding for medium or light loads. If vertical standards with different tube diameters are to be combined in a modular scaffold or in a system, this is only possible with increased effort, for example by using special standards that mediate between the different tube diameters. However, this means an increased use of materials and assembly work, each of which has a negative effect on the costs.

In addition, when using vertical standards with different outer diameters, compatibility with other scaffolding components, in particular with standardized horizontal ledgers and/or with standardized diagonal braces, is no longer guaranteed. Because changing the outside diameter of the pipe changes the distances or clear dimensions between two vertical standards arranged in parallel. The compatibility of the scaffolding components with each other requires compliance with the distances or clear dimensions, which is only possible with the help of special components when changing the tube outer diameter of one or more vertical standards, unless you accept a change in the modular scaffolding's own grid dimensions.

A similar problem can occur in the head and/or foot area of a modular scaffold, particularly if one vertical standard and one spindle are connected instead of two vertical standards. The spindle is used for height compensation, for example to compensate for uneven ground. Since the diameters of the spindle and vertical standard usually differ, the connection is made - depending on where the spindle is used - via so-called head or foot parts. These represent separate scaffolding components that must also be kept available.

The present invention tries to remedy this. In particular, the compatibility of scaffolding components with one another should be improved with the aid of the invention, so that the number of scaffolding components can be reduced. Furthermore, the integration of non-system or cross-system scaffolding components should be simplified, for example in order to meet increased load requirements, if possible without the use of special components and without changing the specified grid dimensions.

The connector with the features of claim 1 and the modular framework with the features of claim 13 are proposed to solve the tasks. Advantageous developments of the invention can be found in the respective dependent claims. Furthermore, a method for the manufacture or erection of a modular framework and the use of a connector within a modular framework are specified.

Disclosure of Invention

• • ein Verbindungsrohr, das zur Verbindung mit mindestens einem Vertikalstiel an zumindest einem Ende, vorzugsweise an beiden Enden, einen Rohrabschnitt mit vergrößertem Außen- und/oder Innendurchmesser aufweist, sowie
• • ein Verbindungselement, dass zur Verbindung mit mindestens einem Horizontalriegel und/oder einer Diagonalstrebe mindestens eine Aufnahmeausnehmung aufweist.

The connector proposed for a modular scaffold includes:

• • a connecting tube, which has a tube section with an enlarged outside and/or inside diameter for connection to at least one vertical post at least at one end, preferably at both ends, and
• • a connecting element for connection to at least one horizontal bar and/or a diagonal strut has at least one receiving recess.

The connecting element is attached to the connecting tube directly via an extension arm or directly on the outer circumference.

The connecting tube of the proposed connector therefore has at least one jump in diameter. This means that the connecting pipe has different outside and/or inside diameters in at least two sections. In this way, the connecting tube enables the connection of two vertical standards with different tube diameters or one vertical standard and one spindle. Because of the connecting element that is also provided, the proposed connector can also be used as a scaffold node. This means that several functions are integrated into one scaffolding component, so that the number of scaffolding components can be reduced. In particular, the use of additional special components for the integration of non-system or cross-system scaffolding components can be dispensed with if the specified grid dimensions are observed. Effort and costs can thus be reduced with the aid of the proposed connector.

A vertical post is preferably connected to the at least one pipe section with an enlarged outside and/or inside diameter via a simple plug-in connection. Furthermore, the vertical post is preferably inserted into the pipe section. The tube section therefore has at least one enlarged inner diameter. This is preferably adapted to the outside diameter of a vertical post for heavy loads, so that such a post can be integrated into the modular scaffold. Furthermore, the outer diameter of the pipe section is preferably also increased in order to ensure a sufficient wall thickness.

The pipe section with an enlarged outer and/or inner diameter is preferably adjoined by a pipe section in the area of which the connecting element for connection to at least one horizontal bar and/or a diagonal strut is arranged. The outer diameter of this tube section is preferably selected in such a way that, in connection with the connecting element and, if necessary, in connection with the boom, distances or clear dimensions are realized which enable the use of standardized horizontal bars and/or diagonal struts. In this case, the use of special components can be dispensed with. At the same time, the specified grid dimensions can be maintained.

Advantageously, the framework components of a modular framework include two different basic types of a connector according to the invention. The two basic types differ in particular with regard to the number of tube sections with an increased outside and/or inside diameter.

In the case of basic type 1, the connecting tube has a tube section with an enlarged outside and/or inside diameter at only one end. This is used to hold a vertical post. At the other end, the connecting tube is designed for connection to a spindle. The preferred place of use for this connector is therefore the head or foot area of a modular scaffold. The proposed connector enables a vertical post to be connected to a spindle without using a separate head or foot part. This function is integrated into the connector so that a separate head or foot part is not required. The connecting element of the connector, which is used for the connection to at least one horizontal bar and/or a diagonal strut, is preferably attached indirectly to the connecting tube on the outer circumference via a cantilever. The cantilever enables the use of standardized ledgers and/or diagonal struts while adhering to the specified grid dimensions.

In basic type 2, the connecting tube of the connector has a tube section with an enlarged outside and/or inside diameter at each of its two ends. This connector is therefore used to connect two vertical standards. These can have the same or different tube diameters, so that vertical standards from other systems can also be integrated, for example to meet increased load requirements.

The connecting element for connection to at least one horizontal bar and/or a diagonal strut is preferably arranged in the area of a central tube section of the connecting tube. Furthermore, the connecting element for connection to at least one horizontal bar and/or a diagonal strut is preferably fastened directly to the outer circumference of the connecting tube. Indirect attachment via a bracket is not necessary with basic type 2, since compliance with the specified grid dimensions when using standardized horizontal ledgers and/or diagonal braces is already guaranteed via the outer diameter of the central pipe section and the connecting element.

The two basic types of a connector according to the invention represent a sensible addition to the available scaffolding components. They can be combined with a large number of different scaffolding components according to the modular principle will. Although they add two more components to the modular system, they ultimately help save components because they make the use of special components superfluous.

In a further development of the invention, it is proposed that the connecting element for connection to at least one horizontal bar and/or a diagonal strut is disc-shaped and aligned perpendicularly to the longitudinal axis of the connecting tube. Depending on the basic type, the disk-shaped connecting element is attached to the connecting tube directly or indirectly via a bracket. The respective vertical orientation of the disk-shaped connecting element facilitates the connection of the at least one horizontal bar and/or the at least one diagonal strut, since the connection angle can be freely selected.

Furthermore, it is proposed that the connecting element has several, for example four, six or eight, receiving recesses for connection to at least one horizontal bar and/or a diagonal strut. The multiple mounting recesses allow the connection of multiple ledgers and/or diagonal struts to a node. This applies in particular if several horizontal ledgers and/or diagonal struts are to be accommodated from different spatial directions. The plurality of receiving recesses are preferably arranged at the same angular distance from one another. This applies in particular when the connecting element which has the receiving recesses surrounds the connecting tube of the connector. Because this creates additional connection options for connecting scaffolding components from different spatial directions. The several receiving recesses can be arranged in a cross or star shape, for example. Furthermore, the connecting element preferably has at least two different types of receiving recesses. These can then be optimally matched to a scaffolding component to be connected in terms of their shape and size.

The connecting element of the proposed connector is—particularly in the case of basic type 2—preferably designed as a rosette surrounding the connecting tube. Furthermore, the rosette preferably has a plurality of receiving recesses which enable scaffolding components to be connected from all spatial directions.

Alternatively, the connecting element of the proposed connector can be fastened at the end to a bracket which is fastened to the connecting tube of the connector at the other end on the outer circumference. This is particularly the case with basic type 1. Fastening the connecting element to the end of the boom means that it can be made shorter, which helps to save material. In addition, the connection of a ledger and/or a diagonal strut is not obstructed by the bracket.

In cross-section, the cantilever preferably has a greater height than width. This measure increases the carrying capacity of the boom. For example, the boom can be made of a box profile that is fastened on edge on the outer circumference of the connecting tube.

Furthermore, the boom preferably has at least one further receiving recess, which enables the connection of a scaffolding component, in particular a diagonal strut. The at least one further receiving recess of the cantilever can be designed, for example, as an eyelet or eye. Alternatively or additionally, it is proposed that the at least one further receiving recess of the extension arm is aligned transversely to the at least one receiving recess of the connecting element. This results in a wide range of connection options for different scaffolding components.

Advantageously, at least two identically designed and each radially aligned cantilevers are fastened at a defined angular distance from one another on the outer circumference of the connecting tube. The angular spacing is preferably 90°, so that the cantilevers run perpendicular to one another. The alignment of the outriggers thus corresponds to the right-angled standard grid of a modular scaffold. Since the cantilevers are of identical design, a connecting element with at least one receiving recess for connection to a horizontal bar and/or a diagonal strut is arranged on each cantilever. Advantageously, the receiving recesses of the connecting elements serve exclusively to connect horizontal bars, while the at least one further receiving recess of the extension arm serves to connect a diagonal strut. The connection situation is equalized in this way.

According to a preferred embodiment of the invention, the pipe section provided at at least one end of the connecting pipe with an enlarged outside and/or inside diameter has a plurality of locking recesses on the shell side. These are used to hold a bolt or screw to create a strong connection between the connector and a vertical standard. For this purpose, the vertical post has corresponding locking recesses that overlap with the locking recesses of the Connecting pipe can be brought. The high-tensile connection makes it possible, for example, to move the modular scaffold with the help of a crane.

The locking recesses are preferably arranged on a circumferential line and/or at the same angular distance from one another. Two locking recesses are preferably located opposite one another so that they are aligned. The bolt or the screw can thus be pushed through both locking recesses, so that the load capacity of the high-tension connection increases. The number of locking recesses can be four, for example.

In addition, it is proposed that the tube section with an enlarged outer and/or inner diameter has a plurality of elongate guide elements extending in the axial direction at the end. These are used to guide a vertical post to be connected to the pipe section, so that the connection of the vertical post is facilitated. Furthermore, the rigidity in the area of the connection is increased by the guide elements. The number of guide elements can be four, for example. The guide elements are preferably arranged at the same angular distance from one another, so that window-like spaces of equal size result between the guide elements. The use of these gaps is described below.

The elongate guide elements are preferably formed at least in regions from the pipe section itself, for example by subsequent cutting of the pipe section. The guide elements can thus be produced comparatively easily and inexpensively. In addition, the outside and inside diameters of the pipe section remain unchanged, so that the connection of a vertical standard is still guaranteed. In order to increase the load-bearing capacity of the guide elements, it is proposed that they be reinforced in the radial direction by additional material. Since the inside diameter of the tube section is preferably adapted to the outside diameter of a vertical post to be accommodated, the additional material used for reinforcement is preferably applied on the outside, so that the inside diameter of the tube section remains unchanged.

According to a further preferred embodiment of the invention, a spigot is formed within the pipe section with an enlarged outer and/or inner diameter, which is arranged concentrically with respect to the pipe section. The spigot expands the connection options. In particular, different vertical posts can be connected to one end of the connector. Depending on the pipe diameter of the vertical post to be connected, this is taken up via the outer pipe section or the inner pin and preferably centered. The centering is realized either via the inside diameter of the pipe section or the outside diameter of the spigot.

The pin preferably has a plurality of locking recesses on the casing side. These are used to hold a bolt or screw to create a strong connection with a vertical standard. For this purpose, the vertical post has corresponding locking recesses, which can be made to overlap with the locking recesses of the pin. The locking recesses of the pin are preferably arranged on a circumferential line and/or at the same angular distance from one another. Two locking recesses are preferably located opposite each other so that they are aligned and the bolt or screw can be inserted into both locking recesses. The number of locking recesses can be four, for example.

Furthermore, it is proposed that the pin protrudes beyond the pipe section with an enlarged outer and/or inner diameter and/or protrudes into an area of the pipe section that has window-like recesses, so that the locking recesses are accessible from the outside. The window-like recesses of the tube section are preferably delimited laterally by the already mentioned elongate guide elements. This means that the window-like recesses can be, in particular, the intermediate spaces between the elongated guide elements that have already been mentioned. The benefit of the gaps is therefore that access to the locking recesses of the pin is guaranteed.

To achieve the object mentioned above, a modular framework with at least one connector according to the invention and at least one vertical post is also proposed, which is inserted at the end into the pipe section with an enlarged outer and/or inner diameter of the connecting pipe for a detachable connection with the connector. Thanks to the enlarged outer and/or inner diameter of the tube section receiving the vertical post, the connector can be connected to different vertical posts. In particular, the vertical standards can have different tube diameters, so that they differ in terms of their load-bearing capacity. In this way, for example, areas subject to high static loads can be equipped with more stable vertical standards to be executed. The load-bearing capacity of the modular scaffolding can thus be scaled depending on the load requirement, without the use of special components. Existing differences in diameter are bridged or compensated for by the connector according to the invention. As a result, the connector enables the use of standardized scaffolding components while adhering to the specified grid dimensions.

Depending on whether the connector is designed according to basic type 1 or basic type 2, the other end of the connecting tube of the connector, i.e. the end that faces away from the tube section with an increased outside and/or inside diameter, is equipped with a spindle or with another one Vertical post detachably connected. The proposed connector can thus be used as a scaffold node, which at the same time assumes the function of a head or foot part (basic type 1) or a special component (basic type 2). In this way, the number of scaffolding components required for the manufacture or erection of a modular scaffolding can be reduced.

Furthermore, a method for producing a modular framework using a connector according to the invention as a framework node is proposed. In the present case, “manufacture” means the erection of a modular scaffold. In the method, the connector is used - especially when changing the system within the modular scaffold - to comply with specified grid dimensions and to maintain specified clear dimensions that are required for the use of standardized scaffolding components, in particular standardized horizontal bars and/or standardized diagonal braces. When integrating a non-system vertical support and/or a spindle that can be used across systems, deviations in the pipe diameters can be compensated for with the help of the connector, so that the use of special components to comply with specified grid dimensions is unnecessary.

In addition, the use of a connector according to the invention as a scaffolding node within a modular scaffolding to maintain specified grid dimensions and to maintain specified clear dimensions is proposed, with the connector preferably being used to connect two vertical posts or one vertical post and a spindle. The two vertical posts can be of the same or different design, in particular have different tube diameters. The difference in diameter is compensated by the connector so that the use of special components can be dispensed with. The use of a connector according to the invention in a modular scaffold facilitates in particular the integration of vertical standards for heavy loads in a modular scaffold for medium or light loads, for example to meet increased load requirements.

Detailed description of the drawings

Of the 1 a first preferred embodiment (basic type 1) of a connector 200 according to the invention for a modular framework 100 can be seen. The connector 200 shown has a connecting pipe 210 with a pipe section 211, the outer and inner diameters of which are enlarged. This means that the connecting pipe 210 has a jump in diameter. The connector 200 can thus be connected at both ends to different uprights 300 or to an upright 300 and a spindle 600 (see FIG 3 ). The jump in diameter compensates for the different pipe diameters.

On the outer circumference of the connecting pipe 210, two extension arms 230 are attached, which are arranged radially in relation to the connecting pipe 210 and at an angular distance of 90° from one another. Each boom 230 has a connecting element 220 on the end face, which is used to connect another scaffolding component, in particular a horizontal bar 400 (see Fig 3 ). The connecting elements 220 each have a receiving recess 221 here. Further receiving recesses 231 are formed in the outriggers 230, which are also used to connect scaffolding components. The configuration and arrangement of the receiving recesses 231 enable, in particular, the connection of diagonal struts 500 (see 3 ).

Again 3 it can be seen that the vertical post 300 and the spindle 600 have different outer diameters. The difference in diameter is compensated by the connector 200. The different outer diameters also mean that the usual distances or clear dimensions between two parallel vertical posts 300 are no longer maintained. This deviation is compensated for by the brackets 230 so that the usual distances or clear dimensions are maintained and the use of standardized horizontal bars 400 and diagonal struts 500 is possible while maintaining the specified grid dimensions.

The connector 200 of 3 has locking recesses 212 in the area of the raw section 211, only one locking recess 212 being visible. Another one is on the back. A bolt or a screw (not shown) can be inserted into these recesses in order to create a connection between the connector 200 and the vertical post 300 that is resistant to tension. Corresponding locking recesses (not shown) are formed in the vertical post 300 for this purpose.

2 shows a further preferred embodiment (basic type 2) of a connector 200 according to the invention for a modular framework 100. In contrast to the connector 200 of 1 the in the 2 connector 200 shown has a tube section 211 with an enlarged outer and inner diameter at each of its two ends. In addition, only one connecting element 220 is provided, which is connected directly to the connecting tube 210 and is designed as a rosette surrounding the connecting tube 210 . Accordingly, the connector 200 has no cantilevers 230 . The maintenance of the usual distances or clear dimensions is ensured here via the outer diameter of the connecting tube 210 and the connecting element 220, so that extension arms 230 are unnecessary. The connecting element 220 has first receiving recesses 221 for connection to horizontal bars 400 (see 4 ) and second receiving recesses 222 for connection to other scaffolding components, for example with diagonal struts 500. The first and second receiving recesses 221, 222 are each arranged at the same distance from one another, resulting in a cross-shaped arrangement in each case, with the first and second receiving recesses 221, 222 alternating.

Of the 2 It can also be seen that the pipe sections 211 with an enlarged outer and inner diameter each have elongated guide elements 213 at their ends. These are formed from the material of the respective tube section 211, for example by cutting, and are reinforced radially outwards by additional material.

As exemplified in the 4 shown, the connector can 2 be connected to two vertical posts 300, which can in particular be vertical posts 300 that have an enlarged outer diameter to meet increased load requirements. The diameter difference to a standardized vertical post 300 is compensated for by the tube sections 211 of the connector 200 provided at both ends. In order to achieve a tight connection between the connector 200 and the vertical posts 300, locking recesses 212 are also provided in the pipe sections 211, into which a bolt or a screw can be inserted.

5 shows an advantageous development of the connector 200 of FIG 2 . The further development consists in the formation of a pin 214 which is arranged inside the upper tube section 211 . The pin 214 protrudes beyond the tube section 211 in such a way that the pin 214 comes to rest between the elongated guide elements 213 . The spigot 214 enables the connector 200 to be connected to a vertical post 300, which is designed, for example, for medium or small loads and consequently has a smaller tube diameter than the tube section 211 (see 6 ). In order to produce a connection between the pin 214 and the vertical post 300 with high tensile strength, locking recesses 215 are provided in the pin 214 . These are used to hold a bolt or a screw (not shown), corresponding locking recesses being formed in the vertical post 300 . The locking recesses 215 are arranged on a circumferential line at the same angular distance from one another, each offset by 45° to the guide elements 213, so that the locking recesses 215 each come to lie centrally within a window-like recess 216 between two guide elements 213. This ensures that the locking recesses 215 are accessible (see 6 ).

As exemplified in the 6 and 7 shown, the connector 200 of 5 be connected to different vertical posts 300, with the pin 214 within the upper tube section 211 offering an additional connection option. Depending on the outside or inside diameter of the vertical post 300 to be connected, it is centered either by the tube section 211 or the pin 214 .

In the embodiment of 7 the lower vertical post 300 has a connecting element which essentially corresponds to the connecting element 220 of the connector 200 . A horizontal bar 400 can thus also be connected to the connecting element of the vertical post 300 . This is exemplified in the 8th shown. The window-like recesses 216 in the lower tube section 211 of the connector 200 are dimensioned in such a way that the connection of the horizontal bar 400 is not impeded. The spaces between the elongate guide members 213 can thus have another benefit.

A further development of the connector 200 of 5 is in the 9 shown. Here both ends of the connector 200 are formed identically. This means that the lower tube section 211 also has an internal pin 214 . The lower end of the connector 200 thus also has expanded connection options.

However, a connector 200 according to the invention does not necessarily have to be equipped with a pin 214 in order to receive a vertical post 300 whose outside diameter is not adapted to the inside diameter of a pipe section 211 formed at the end. As exemplified in the 10 shown, an adapter tube 310 can alternatively be used between the connector 200 and the vertical post 300 .
