Description

The invention relates to a rod-shaped scaffolding element for connection to a first projection recess of a scaffolding part. The invention further relates to a scaffolding part with such a scaffolding element and a method for assembling such a scaffolding element.

It is known to provide a simple connection mechanism for connecting a rod-shaped scaffolding element to a scaffolding component. The rod-shaped scaffolding element can be designed in particular in the form of a railing rod or a scaffolding diagonal. The scaffolding component can be designed, for example, in the form of a horizontal bar.

The connection mechanism typically has a recess on the rod-shaped framework element, which is guided onto a projection on the framework component. Such a connection mechanism is, for example, from DE 20 2008 001 019 U1 , the US 6,006,862A , the DE 196 33 092 A1 , the DE 10 2004 005 636 A1 , the DE 10 2008 005 814 B4 , the DE 10 2011 014 614 A1 , the EP 0 234 657 A2 , the EP 1 262 611 A2 , the EP 1 589 162 A1 , the GB 901.351A , the GB 1 242 224 A , the JP 2004-076468 A , the JP 2006-226001 A , the U.S. 2,681,834A , the US 2,845,307A and the US 3,323,271A known. Furthermore, from the DE 1 559 069 A a connection mechanism has become known in which a rod-shaped framework element has a wedge-shaped opening on its end face has, in which a wedge-shaped projection on a scaffolding component in the form of a scaffolding post can be inserted. the WO 2017/013289 A1 discloses a scaffold diagonal with a connecting element having a projection. The connecting element can be inserted into an opening of a further frame part by a pivoting movement.

The known connection mechanisms have the disadvantage that they have complex mechanics with movable components, can only be manufactured at high cost and/or have to be moved during assembly, taking up so much space that assembly in cramped conditions is often impossible. Scaffolding diagonals in particular often have to be swung out over a wide area for assembly. In many cases, however, this swinging out is not possible due to other scaffolding components or building walls.

The object of the invention is therefore to provide a rod-shaped scaffolding element that is both structurally simple and can therefore be manufactured inexpensively and can also be easily assembled in a confined space. The object of the invention is also to provide a scaffolding part with such a scaffolding element and a method for assembling such a scaffolding part.

This object is achieved by a scaffolding element having the features of claim 1, a scaffolding part having the features of claim 10 and a method for assembling a scaffolding element according to claim 12. The dependent claims reflect preferred developments.

In the context of the present invention, the designations “top”, “bottom”, “horizontal”, “vertical”, etc. refer to the assembled state of the respective component. Furthermore, the term "transverse" means any non-parallel or congruent orientation.

The object according to the invention is thus achieved by an elongate scaffolding element in the form of a scaffolding diagonal. The scaffolding element has a scaffolding element body, preferably tubular, on which a first connecting element is attached in the region of a first end of the scaffolding element is arranged or formed. The first connecting element has a projection which can be inserted into a first projection recess of a scaffolding component in order to engage behind an edge of the projection recess. The projection extends transversely to the longitudinal axis of the scaffolding element body.

This enables the framework element to be assembled by pivoting the framework element about the longitudinal axis of the framework element body or by pivoting the framework element about an axis which runs parallel to the longitudinal axis of the framework element body. The space required for assembling the scaffolding element is therefore minimal. In addition, the scaffolding element is structurally surprisingly simple in design and can therefore be manufactured inexpensively.

The projection is preferably formed at a distance from the skeletal element body by a spacing portion of the first connecting element. The longitudinal axis of the projection can extend offset to the longitudinal axis of the framework element body. As a result, the scaffolding element can be pivoted towards the scaffolding component in a particularly simple manner for its assembly.

In addition to the offset alignment of the longitudinal axis of the projection to the longitudinal axis of the scaffolding element body, the longitudinal axis of the projection can be at an angle of 90°±30°, in particular at an angle of 90°±20°, preferably at an angle of 90°±10°, extend to the longitudinal axis of the scaffolding member body.

The spacer portion is preferably L-shaped together with the projection. The longitudinal axis of the spacer section can enclose an angle of 90°±30°, in particular an angle of 90°±20°, preferably an angle of 90°±10°, with the longitudinal axis of the framework element body. The longitudinal axis of the projection can enclose an angle of 90°±30°, in particular an angle of 90°±20°, preferably an angle of 90°±10°, with the longitudinal axis of the spacer section.

In a particularly preferred embodiment of the framework element, the projection is rigid relative to the framework element body.

The first connecting element can be solid and/or designed in one piece. The first connecting element is preferably flattened or rounded on its side facing away from the body of the scaffolding element in order to facilitate pivoting of the scaffolding element.

The spacer section can be designed in the shape of a bolt to further simplify production while at the same time providing high stability of the framework element. Manufacture is further simplified if the first connecting element has a U-shaped section molded onto the spacing section.

The first connecting element preferably has a cuboid outer contour which prevents twisting of the first connecting element. The U-shaped section of the first connecting element is preferably accommodated in a U-shaped section of the skeletal element body.

According to the invention, the framework element has a second connection element on the body of the framework element in the region of the first connection element. As a result, sections of the framework part that are spaced apart by different distances can be connected by means of the framework element.

The manufacture of the scaffolding element is made significantly easier because, according to the invention, the second connecting element and the first connecting element are of identical design. At the second end of the framework element, a securing element for connecting the framework element to a second projection recess can be arranged or formed on the body of the framework element. The securing element is preferably designed to be movable relative to the framework element body.

The framework element can also have a safety bolt, in particular in the form of a socket bolt, on which the safety element is preferably arranged, in particular in a pivotable manner. The safety bolt can be designed for at least partial insertion into a second projection recess of a scaffolding component in order to keep the scaffolding element mounted in a torsion-proof manner.

In the area of the safety bolt, the scaffolding element can have a further safety bolt, on which another safety element is preferably arranged, in particular pivotably. The additional safety bolt can be designed for at least partial introduction into a second projection recess of a scaffolding component. Using the second safety bolt, even more different distances or lengths can be covered with one scaffolding element.

The object according to the invention is further achieved by a scaffolding part with a scaffolding component, a first protrusion recess and a scaffolding element as described above, the scaffolding element being mounted on the first protrusion recess in such a way that the protrusion of the first connecting element overlaps the edge of the first protrusion -Recess behind. In a further preferred embodiment of the scaffolding part, the first projection recess is provided in a scaffolding component which is designed in the form of a horizontal connector, i.e. a scaffolding beam that can be or is arranged horizontally.

2. B) Schwenken des Gerüstelements um die Längsachse des Gerüstelementkörpers oder um eine Achse parallel zum Gerüstelementkörper, sodass der erste Vorsprung den Rand der ersten Vorsprungs-Ausnehmung zumindest abschnittsweise hintergreift.

The object according to the invention is also achieved by a method for mounting a scaffolding element as described above on a scaffolding component according to claim 12, with the method steps:

1. A) inserting a first projection of the framework element into a first projection recess of the framework component;
2. B) Pivoting the framework element about the longitudinal axis of the framework element body or about an axis parallel to the framework element body, so that the first projection engages behind the edge of the first projection recess at least in sections.

In particular, the method has the following method step:

Fig. 1a shows a scaffolding part 10 with vertical scaffolding posts 12a, 12b, 12c, 12d. The scaffolding posts 12a-12d are connected by means of scaffolding components 14a, 14b, here in the form of horizontal bars. The framework component 14a and the framework component 14b are in particular of the same design. The framework components 14a, 14b are inserted into connection plates 16a, 16b, 16c, 16d , which are rosette-shaped here. The connecting plates 16a-16d are connected to the scaffolding posts 12a-12d, in particular welded to the scaffolding posts 12a-12d.

A framework element 18 is provided to reinforce the framework part 10 . The framework element 18 is designed to connect its two ends to the framework components 14a, 14b. In order to connect the framework element 18 , the framework component 14a has a first projection recess 20 and the framework component 14b has a second projection recess 22 .

Fig. 1b shows the framework part 10 in the area of the first projection recess 20. From Fig. 1b It can be seen that the framework element 18 has a projection 24 which, when the framework element 18 is assembled, reaches behind the edge 26 of the first projection recess 20 in sections. As indicated by an arrow 28 , during assembly of the framework element 18 a pivoting movement of the framework element 18 takes place in order to insert the projection 24 into the first projection recess 20 and then to achieve the hooking of the projection 24 on the edge 26 .

The projection 24 is part of a first connecting element 30. The first connecting element 30 is solid and preferably has a U-shaped end section 32 . The U-shaped end portion 32 of the first connecting member 30 is fitted into a U-shaped end portion 34 of a skeletal member body 36 of the skeletal member 18 . In this way, a particularly strong, in particular non-rotatable, but easy-to-manufacture connection is created between the first connecting element 30 and the scaffolding element body 36 .

1c shows the scaffolding element 18 with the first connecting element 30 and a securing element 38. The securing element 38 is arranged or formed directly or indirectly on an end region of the scaffolding element body 36, which connects to the end region of the scaffolding element body 36 with the first Connecting element 30 is opposite. In the present case, the securing element 38 can be moved, pivoted here, and is arranged on a securing bolt 40 . The safety bolt 40 can have any desired cross section, for example a polygonal cross section. The safety bolt preferably has a circular or elliptical cross-section. The securing bolt 40 can be solid.

Fig. 1d shows the in Fig. 1b Circular framed part of the framework element 18. Fig. 1d 12 illustrates the finger-shaped configuration of the first connecting element 30 in the region of the projection 24. The projection 24 is spaced from the framework element body 36 by a spacer section 42 .

The longitudinal axis 44 of the spacing section 42 intersects the longitudinal axis 46 of the projection 24 at an angle of 90°±30°, in particular at an angle of 90°±20°, preferably at an angle of 90°±10°. The longitudinal axis 44 of the spacing section 42 also intersects the longitudinal axis 48 of the framework element body 36 at an angle of 90°±30°, in particular at an angle of 90°±20°, preferably at an angle of 90°±10°.

Out of Fig. 1d It can also be seen that the scaffolding element body 36 preferably has a first recess 50 through which the first connecting element 30 passes.

Manufacture and assembly of the framework element 18 are facilitated if the framework element body 36 is mirror-symmetrical to a central mirror plane S (see 1c ) is formed, which extends perpendicularly to the longitudinal axis 48 of the framework element body 36 .

Fig. 1e shows the framework part 10 (cf. Fig. 1a ) with fully assembled scaffold element 18. The first connecting element 30 (see Fig. 1d ) of the framework element 18 is at least partially inserted into the first projection recess 20 (see Fig. 1a ) has been introduced and engages behind the edge 26 (please refer Fig. 1b ) of the framework component 14a (see Fig. 1a ). Furthermore, the framework element 18 has been pivoted about the longitudinal axis 44 of the spacing section 42 . Finally, the securing element 38 (see 1c ) through the second projection recess 22 (see Fig. 1a ) has been guided and engages behind the edge of the scaffolding component 14b (see Fig. 1a ) in the area of the second projection recess 22 (see Fig. 1a ).

The framework element 18 is designed in the form of a framework diagonal. 1f shows the framework part 10 according to FIG Fig. 1e in the area of Line FF. Out of 1f It can be seen that in the installed state of the first connecting element 30 the clear width of the first projection recess 20 corresponds with a loose fit to the (cross-sectional) thickness of the first connecting element 30 in the area of the first projection recess 20 .

In the transition area between the projection 24 and the spacing section 42 the connecting element 30 has a rounded or flattened area 52 . This facilitates pivoting in or out of the scaffolding element 18 for its assembly or disassembly on or from the scaffolding component 14a.

Figure 2a shows a further embodiment of a part of a framework element 18a. The framework element 18a has a first connecting element 30 and a second connecting element 54 in an end region of the framework element 18a. The second connecting element 54 is arranged or formed parallel to the longitudinal axis 48 of a framework element body 36 of the framework element 18a offset to the first connecting element 30 on the framework element body 36 . The scaffolding element body 36 preferably has a second recess 56 through which the second connecting element 54 passes. The first connecting element 30 and the second connecting element 54 are of identical design. The scaffolding element 18a can be attached to a scaffolding component 14a (cf. Fig. 1a ) are connected, so that in a simple way and Way different effective connection lengths of the framework element 18a can be achieved.

Figure 2b shows a scaffolding component 14a. The framework component 14a according to Figure 2b corresponds to the scaffolding component 14a according to Fig. 1a . However, the scaffolding component 14a according to Figure 2b in at least one end area, in particular in its two end areas, in each case more than one first projection recess 20a, 20b, 20c, 20d, 20e, 20f, in particular in each end area exactly three projection recesses 20a-20f.

Figure 2c shows a framework part 10 with the framework component 14a according to FIG Figure 2b . The framework part 10 also has a framework component 14b . The scaffolding component 14a and the scaffolding component 14b are in particular of the same design. The framework component 14b has a plurality of second projection recesses 22a, 22b, 22c, 22d, 22e, 22f . The first projection recesses 20a-20f, together with the second projection recesses 22a-22f, enable the connection of the framework components 14a, 14b by means of parallel framework elements 18a, 18b. The framework elements 18a, 18b are preferably of identical design. As a result, the framework part 10 is particularly stable.

When using two parallel framework elements 18a, 18b, the outer projection recesses 20a, 20c, 22d, 22f or 20d, 20f, 22a, 22c are preferably occupied by the framework elements 18a, 18b. As a result, another framework element 18 (in Figure 2c not shown) can be mounted in the projection recesses 20b, 22e or 20e, 22b. When using a single scaffold member 18 (in Figure 2c not shown), this is preferably mounted in the central projection recesses 20b, 22e or 20e, 22b.

The framework element 18, 18a, 18b can be passed through at one end by means of a first connecting element 30 Pivoting of the scaffolding element 18, 18a, 18b about its longitudinal axis 48 or about an axis which extends essentially parallel to its longitudinal axis 48, can be hooked to a first projection recess 20, 20a-20f of a scaffolding component 14a, 14b. At the other end, the scaffolding element 18, 18a, 18b can have a securing bolt 40, which can be inserted into a second projection recess 22, 22a-22f of a scaffolding component 14a, 14b, in order to prevent the scaffolding element 18, 18a, 18b from pivoting about its longitudinal axis 48 or to prevent an axis parallel to its longitudinal axis 48. The securing bolt 40 can be secured in particular by a securing element 38 on the scaffolding component 14a, 14b. The first connecting element 30 can in particular be hook-shaped, with a projection 24 on the free end of the first connecting element 30 being able to engage behind the edge 26 of the first projection recess 20, 20a-20f. A spacer portion 42 extending away from the longitudinal direction of the skeleton element body 36 may be provided between the projection 24 and a skeletal element body 36 . The projection 24 can extend away from the spacing section 42 at right angles of ±20°, in particular at right angles of ±10°, preferably at right angles of ±5°.
