c) each coupling section has a backdrop and scaffold pins of the scaffold in the scenes are displaceable feasible.

The invention further relates to a scaffold with such

Guardrail.

The above-mentioned railing spar or the aforementioned framework have become known from JP 2006-226001 A. In this document, different coupling sections of railing spars are shown in Figure 4, wherein formed in the coupling sections scenes are designed to receive a skeleton pin. Furthermore, EP 1 262 611 A2 discloses a railing spar for the construction of a leading scaffold, wherein the railing spar is arranged on a pin with an angular head.

JP 2004-076468 A discloses a scaffolding pin for suspending a scenery of a railing spar. The scaffolding pin is rotatably mounted on a scaffolding frame.

From DE 10 2004 005 636 AI is a scaffolding pin with a

mushroom-shaped projection at the end known. The scaffolding pin is S-shaped in the direction of its longitudinal axis

educated.

Railing spars have become known from US Pat. No. 2,681,834 A and GB 1 242 224 A, which can be arranged on a scaffold spigot with a circular projection at the end. The railing spars have one

Retaining Holm, are pivotally mounted on the coupling portions, wherein the coupling portions each have a backdrop.

US 2,845,307 A discloses a scaffolding pin in the form of a screw. A also disclosed in this document railing rail is connected by a latch mechanism with the scaffold pin.

DE 10 2008 005 814 B4, DE 10 2011 014 614 A1, DE 20 2008 001 019 U 1 and US Pat. No. 6,006,862 A have disclosed railing spars which have scaffold pins in the form of differently shaped hooks. Finally, EP 0 234 657 A2 discloses a railing spar having a retaining spar and a coupling portion rigidly connected to the retaining spar. In the coupling section a backdrop is formed, in which a horseshoe-shaped scaffold pin is receivable. The scaffolding pin is rotatable in the scenery, but not displaceable.

Object of the present invention is in contrast, in a structurally particularly simple way to simplify the installation of a railing spar on a scaffold.

This object is achieved by a railing hoof according to claim 1. The dependent claims indicate expedient developments.

The object is thus achieved according to the invention by a railing spar for a scaffold, wherein the railing spar has the following features:

a) in the direction of the longitudinal axis of the railing spar

extending retaining spar;

b) two rigidly connected to the spaced apart in the direction of the longitudinal axis of the railing ends of the retaining spar

Coupling sections, where

c) each coupling section has a slide and scaffold pins of the scaffold are slidably guided in the scenes, where d) the scenes each have a V-shaped basic shape and e) the scenes each have a first link section,

whose longitudinal axis is transverse to the longitudinal axis of the railing spar and

f) the scenes each have a second gate section,

whose longitudinal axis is transverse to the longitudinal axis of the railing spar and transverse to the longitudinal axis of the first gate section. The immovable, connected to the retaining spar, at least two, in particular exactly two, coupling sections allow a structurally particularly simple embodiment of the invention

Railings spar. By means of the substantially V-shaped backdrop of the railing rail can be fixed regardless of its orientation on the scaffolding pin. The scaffold pin is received in the after mounting each top leg of the V-shaped backdrop.

The longitudinal axes of the link sections consist of infinitely long fictitious lines that extend through the beginning and end of the respective gate section.

The term "across" becomes a non-parallel orientation

Understood.

The scenes are preferably formed in the form of through holes.

The longitudinal axes of the first and second link sections can intersect the longitudinal axis of the railing spar at an angle of 1 ° to 89 °. In particular, the longitudinal axes of the first and second intersect

Gate sections the longitudinal axis of the railing spar at an angle of 2 ° to 60 °, preferably at an angle of 3 ° to 30 °, more preferably at an angle of 4 ° to 20 °.

In order to achieve the same assembly behavior of the railing spar on the scaffold spigot independently of the orientation of the railing spar, the second slotted section of each coupling section is preferred

mirror-symmetrical to the first gate section of the same

Coupling section formed. The construction and production of the railing rail will continue

simplified if the symmetry axis for mirroring the previously

mentioned link sections along the longitudinal axis of the railing spar runs.

In a particularly preferred embodiment of the invention, the first and second link section of each scenery by a third

Connected gate section, whose longitudinal axis transverse to the longitudinal axis of the first link section and transverse to the longitudinal axis of the second

Sliding section runs. In this case, the scenery is stepped on the scaffolding pin, whereby the fitter "feels" during the installation of the railing rail, that the railing rail is firmly connected to the scaffolding pin Furthermore, by the step-shaped design of the scenery inadvertent unthreading of the scenery relative to

Scaffolding pin prevented.

The construction of the railing rail is thereby further simplified if the longitudinal axes of the third link sections are perpendicular to the longitudinal axis of the railing spar.

At least one slide can be connected to a passage opening for the introduction of the truss pin.

Preferably, both scenes are each connected to a passage opening for the introduction of the truss pin. The passage opening can be connected directly to the first and second gate section. Alternatively, the passage opening may be directly connected to the third gate section. However, in each case a fourth gate section is in each case preferably directly connected to one Passage opening connected, wherein the fourth link section a connecting channel between the passage opening and the third

Scenes section represents. The longitudinal axis of the fourth link section preferably extends along the longitudinal axis of the railing spar.

The link sections preferably have the same width. The width of the link sections is preferably chosen so that the scaffolding pin is feasible with a clearance in the gate sections.

The passage opening may have a greater width or clear width than the first, second, third and / or fourth

Gate sections. The railing spar is in this case after the

Picking up the scaffold pin in the opening and moving the railing spar - so that the scaffolding pin is in the scenery - firmly held on the scaffolding pin.

The design of the railing spar is structurally further simplified if the cross section of the passage opening has a circular basic shape.

The scenes are preferably Y-shaped and open at the lower end of the Y through the fourth gate section in the passage opening.

The link sections are preferably along their respective

Longitudinal axis formed straight, ie the scaffold pin is feasible in a straight path in the gate sections. The effectively usable passage width of a scaffold can be increased if the coupling sections are flat. Furthermore, the scenes are easier to produce in this case.

The railing spar can be mounted rotated with respect to its longitudinal axis by 180 °, when the railing spar is formed symmetrically to its center plane extending along the longitudinal axis of the railing spar, wherein the planes of the scenes are formed perpendicular to the center plane. The plane of the scenes is understood to be the plane in which the scenes are formed, i. the plane which runs parallel to, in particular flattened, surface of the coupling portions.

The first backdrop is preferably identical to the second backdrop

educated. Furthermore, the scenes preferably with respect to the

Longitudinal axis of Geländerhoims the same orientation. Here, the scenes are preferably oriented towards each other so that the longitudinal axes of the first link sections parallel to each other. By in the aforementioned manner "in the same direction" trained scenes, it is possible, with a scaffold erected a single railing spar temporarily

To expand, for example, building material on the scaffolding level

to be delivered.

The object of the invention is further achieved by a scaffold, ie a scaffolding, with a scaffold strut, arranged on the scaffold strut or scaffold construction and a previously described railing spar, the scaffold pin is slidably disposed in the backdrop. Design and assembly of the scaffold are significantly simplified when the scaffold is straight along its longitudinal axis.

In a particularly preferred embodiment of the invention is the

Scaffolding pin mushroom-shaped. The scaffolding pin has a straight pin, at the end of a rounded head is designed with a larger diameter than the bolt. The head is in this case preferably rounded at its free end and formed flat to the straight bolt.

The gate width, i. the clear width of the scenes, is preferably larger than the pin diameter, but narrower than the diameter of the rounded head. As a result, the railing spar is securely held to the scaffold strut, wherein the railing spar is slidable with a clearance fit relative to the scaffold strut.

Particularly preferably, the scaffold spigot does not extend beyond the external dimension of the railing spar determined parallel to the longitudinal axis of the scaffold spigot. The passage width of the framework is thereby not limited by the scaffold, but only by the cross section of the railing spar.

In order to achieve a particularly high level of security for the installer of the scaffold, the scaffold is preferably designed in the form of a leading scaffold. It is possible to mount a tread of the scaffold only after the Geianderholm.

Further features and advantages of the invention will become apparent from the following detailed description of an embodiment of the Invention, reference to the figures of the drawing, the essential features of the invention shows and from the claims.

The features shown in the drawing are shown such that the features of the invention can be made clearly visible. The various features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.

Mounting a railing spar to scaffold struts;

Fig. 2a is a plan view of the mounted railing spar;

2b shows a side view of the railing spar; and

Fig. 3 is a perspective view of a scaffold strut.

FIG. 1 a shows a framework 10 with a first frame element 12 and a second frame element 14. A third frame element 16 is attached to the first frame element 12 in the direction of an arrow 18. The third frame element 16 has a framework strut 20 with a framework pin 22. The scaffolding pin 22 is preferably by a

Stud welding method attached to the framework strut 20. The

Stud welding allows a high

Level of automation in the manufacture of the framework 10. Figure lb shows the further assembly of the frame 10, wherein a Gelanderhoim 24 is mounted on the scaffold pin 22.

According to Figure lc 10 of the further assembly of the frame

Railing rail 24 hung in a scaffolding pin 26. Of the

Scaffolding pin 26 is preferably attached to a fourth frame member 28 by a stud welding method. Subsequently, the

Gelanderholm 24 pivoted by lifting the fourth frame member 28 about the scaffold pin 22 upwards and the fourth

Frame member 28 in the direction of an arrow 30 to the second

Frame element 14 inserted.

On the frame members 16, 28, a second railing spar (not shown) may be arranged, which is parallel to the railing rail 24 and is pivoted simultaneously with the railing rail 24 when lifting the fourth frame member 28. The second, not shown

Railing spar can be identical to the railing rail 24.

The third frame element 16 and the fourth frame element 28 have transverse webs 32, 34. On the transverse webs 32, 34, a covering element (not shown) can be placed to allow a construction worker walking the scaffold 10 at a greater height. As can be seen from Figure lc, the covering element is first placed on the transverse webs 32, 34 when the railing rail 24 is already mounted. The framework 10 is thus a framework with leading railing spars.

FIG. 2 a shows a partial view of the framework 10. From FIG. 2 a it can be seen that the railing rail 24 has a retaining rail 36. Of the

Rückhaiteholm 36 extends in the direction of the longitudinal axis 38 of the railing spar 24. At the ends of the retaining spar 36 are - in Direction of the longitudinal axis 38 seen - coupling sections 40, 42 of the railing rail 24 is arranged. The coupling portions 40, 42 are formed flat and each rigid with the longitudinal ends of the

Retaining Holms 36 connected.

The railing rail 24 is symmetrical to its center plane 44

formed, wherein the center plane 44 extends in Figure 2a in the plane of the paper or out of the plane of the paper out.

In Figure 2a, the framework strut 20 is arranged with it

Scaffold pin 22 and a scaffold strut 48 with scaffolding pin 26 arranged thereon. The railing rail 24 has scenes 50, 52 which engage behind the framework pins 22, 26 in order to secure the railing rail 24 to the framework struts 20, 48. The scenes 50, 52 are substantially V-shaped and connected to passages 54, 56. The clear width of the passage openings 54, 56 is selected such that the mushroom-head-shaped ends of the framework pins 22, 26 can be guided with a clearance fit through the passage openings 54, 56. In contrast, the width of the scenes 50, 52 chosen smaller than the inside diameter of the passage openings 54, 56. The width of the scenes 50, 52 is further selected smaller than the diameter of the mushroom-shaped ends of the scaffold pins 22, 26, so that the scenes 50, 52nd the

Scaffold pins 22, 26 engage behind in the assembled state of the railing spar 24. In other words, the scaffold pins 22, 26 have a mushroom-shaped basic shape, wherein the "mushroom head" of the scaffold pins 22, 26 can be guided with a clearance fit through the through openings 54, 56 and the "stem" of the scaffold pins 22, 26, ie a bolt of the

Scaffolding pin 22, 26, with a clearance in the scenes 50, 52 is displaceable. For a detailed view of the truss pin 22 will refer to Fig. 3. The scaffolding pin 26 is identical to the

Scaffolding pin 22 is formed.

The scenes 50, 52 have first link sections 58, 60 and second link sections 62, 64, each by third

Slotted sections 66, 68 are connected. The passage openings 54, 56 are over fourth gate sections 70, 72 with the third

Slotted sections 66, 68 connected. The fourth link sections 70, 72 extend along the longitudinal axis 38 of the railing spar 24. By the third link sections 66, 68 and the fourth Kuussabschnitte 70, 72, the V-shaped basic shape of the scenes 50, 52 is specified to a Y-shape. The passage openings 54, 56 are formed at the lower end of the Y-shape.

The first link sections 58, 60, and the second

Slotted sections 62, 64 are transverse to the longitudinal axis 38, i. neither parallel nor congruent with the longitudinal axis 38 formed.

Furthermore, the first link sections 58, 60 extend transversely to the second link sections 62, 64. This is illustrated in FIG. 2 a by way of example with reference to the first link section 60, whose

Longitudinal axis 74 transverse to the longitudinal axis 38 of the railing rail 24 extends. The longitudinal axis 74 intersects the longitudinal axis 38 at an angle α between 3 ° and 15 °. Furthermore, the longitudinal axis 76 of the second sliding section 64 extends transversely to the longitudinal axis 38.

The longitudinal axes (not shown) of the third link sections 66, 68 extend transversely to the longitudinal axes of the first link sections 58, 60 and transversely to the longitudinal axes of the second link sections 62, 64. Furthermore, the longitudinal axes of the third link sections 66, 68 extend transversely to the longitudinal axis 38, in particular perpendicular to the longitudinal axis 38. The connection between the fourth link sections 70, 72 and the first link sections 58, 60 and the second

Sliding sections 62, 64 are step-shaped, so that - as indicated by arrows 78 - the displacement of the railing rail 24 during its mounting runs step-shaped.

FIG. 2b shows the framework 10 in a side view. From Figure 2b it can be seen that the scaffolding pin 26 - as by a

Double arrow 80 indicated - in the direction of its longitudinal axis does not extend beyond the cross section of the railing rail 24. The one by one

Double arrow 82 indicated passage width of the frame 10 is thereby maximized. Furthermore, Fig. 2b shows that the scaffold pin 26 with respect to its longitudinal axis (not shown) is straight.

FIG. 3 shows the framework strut 20 with scaffolding pin 22 fastened thereto. It can be seen from FIG. 3 that the scaffold peg 22 is designed to be radially symmetrical with respect to its longitudinal axis 84. The longitudinal axis 84 of

Scaffold pin 22 is perpendicular to the longitudinal axis 86 of the

Fig. 3 further shows that the scaffolding pin 22 has a cylindrical portion 88 and an adjoining thereto

End portion 90 has. The end portion 90 is transverse to

Longitudinal axis 84 has a larger cross-section than the cylindrical portion 88. The end portion 90 may be formed compressed-elliptical rotation. Alternatively, the end portion 90 may be formed in the form of a disk. Particularly preferred is the axial to

Scaffold strut 20 side facing the end portion 90 flat and axially away from the frame strut 20 side facing away from the end portion 90 is round.
