Description

The invention relates to a scaffold part in the form of a front railing for securing completion of a front side of a walk-in scaffold, wherein the end railing has a bow-shaped basic shape. The invention further relates to a scaffold with such a scaffolding part and a method for assembling the scaffold.

It is known to provide end railings for securing a front side of a scaffold. Such end face railing is for example from the EP 0 918 912 B1 known. However, this front railing can only be mounted when the associated scaffolding level has been provided with a walk-in scaffold decking. This means that the scaffolder is not secured against falling during the assembly of the front railing on the front side.

Therefore, the reveals DE 201 13 041 U1 an advanced end railing. The known front railing can be fastened to the framework via stop tongues and threading clamps. It has two vertical pins, which are connected to each other via a base portion end. The known end railing is installed before the installation of the associated walk-on covering from the lower level and then secured by the support of a walk-on covering on a Abkragung the front side railing on the scaffold. For this, the known end railing on a pivotable handling part, which is hinged down to mount the front side railing in the construction of the framework of a lower framework level can. This type of assembly is also referred to as "leading".

The pivotable handling part requires a complex and therefore costly installation. It also means extra weight.

The object of the present invention, in contrast, is to provide a previously mentioned scaffold part and a scaffold with such a scaffold part, which are structurally significantly simplified and made lighter. It is also an object of the present invention to provide a method for mounting such an end railing.

This object is achieved by a scaffolding part in the form of a front railing according to claim 1, a scaffold according to claim 13 and a method according to claim 15. The dependent claims give preferred developments again.

The object of the invention is thus achieved by a front railing for securing completion of an end face of a walkable scaffold, wherein the end railing has a bow-shaped basic shape, wherein the end railing has a freely projecting first vertical pin and a freely projecting second vertical pin, each in a recess of a scaffold recording of Scaffold are feasible to secure the front railing at the bottom of the scaffold shots.

The frameworks are preferably in the form of rosettes. Furthermore, the recesses are preferably formed in the form of through holes. In this case, a rosette or perforated disc is understood to mean a flat disc with an arbitrary outer contour that extends perpendicularly away from the central axis of a scaffolding pedestal and is provided with at least one, preferably up to eight, preferably all-round, recess (s) , B. bolts or brackets can be attached. Usually, such frameworks at regular intervals, the so-called. Höhenrastermaß, on the vertical stems of z. B. module stands arranged.

In contrast to that from the DE 201 13 041 U1 Thus, the end face railing according to the invention has at least two freely projecting vertical pins, which can each be introduced into a recess, in particular in the form of a passage recess, of a framework receptacle of the framework. By using the free ends of the front railing for attachment to the frame receptacles, the end railing according to the invention can be formed without a base section connecting the vertical pins. As a result, the front side railing is much easier and easier. The front side railing according to the invention thereby enables a leading-up assembly, ie an attachment of the front side railing of a lower framework level. Furthermore, the inventive end railings - in contrast to the end railing according to the DE 201 13 041 U1 - no further downwardly projecting handling parts. The front side railing according to the invention can remain in the mounted position, ie does not constitute an additional component required during assembly.

In the context of the present invention, the terms "top", "bottom", "top", "bottom" and "horizontally spaced" refer to the mounted state of the front railing. Furthermore, in the context of the present invention, the term "rosette" also encompasses a scaffold receiving part which does not completely enclose a scaffold post.

The front side railing according to the invention thus has on its underside on the vertical pins for attachment of the front side railing to scaffold receptacles.

The vertical pins can each have a minimum length of 150 mm. As a result, the front side railing can be kept in a secure manner to the scaffold recordings without further protection against unwanted lifting is required.

Preferably, the first vertical pin has a first securing pawl, by means of which the first vertical pin can be secured to the first frame receptacle after it has been inserted into a first frame receptacle of the frame. The first securing pawl prevents the first vertical pin from being pulled out of the first framework receptacle when the end railing is subjected to a vertical tension.

Further preferably, the second vertical pin has a second securing pawl, by means of which the second vertical pin can be secured to the second frame receptacle after insertion into a second frame receptacle of the framework. By the second securing pawl the front side railing can be arranged particularly secure on the scaffold.

A structurally particularly simple solution of the object according to the invention with simultaneous secure attachment of the front railing is achieved when the first safety pawl with vertical alignment of the first vertical pin and / or the second safety pawl with vertical alignment of the second vertical pin in the form of a held by gravity in the locked state safety latch is / are trained. The first securing pawl or the second securing pawl can / can thereby be formed without a spring element.

In a further preferred embodiment of the invention, the front side railing - except for (one) optional locking pawl (s) - formed in one piece. In the context of the present invention, a one-part design is understood to mean a firmly connected, rigid construction without individual parts that are movable relative to one another. The one-piece design simplifies the construction of the front railing and significantly reduces its weight.

In a further preferred embodiment of the invention, the end railing horizontally spaced from the first vertical pin on a first gripping bar. Alternatively or additionally, the front side railing to the second vertical pin horizontally spaced have a second gripping bar. The gripping bar stands or the gripping bars are preferably free from the top of the front side railing down from. By gripping bar or the gripping bars can be dispensed with a pivotable handling part, the front side railing still remains easily accessible at the bottom. The gripping bar allows or the gripping bars allow comfortable leading-edge mounting of the front railing. Due to the horizontal spacing of the gripping bar or the gripping bars from the first or second rack bar, there is no danger for a fitter of the front railing to pinch a hand between the end side railing and the scaffold post during the assembly of the front side railing. In addition to the horizontal spacing of the gripping bar or the gripping bars may be spaced vertically to the vertical pin.

The backup of a worker with mounted end railing is primarily by a bracket of the front railing. The bracket in this case comprises a headband which is arranged or formed between two vertical bow bars. The headband is formed transversely to the central longitudinal axis of the front railing.

For the top side attachment of the front railing, the end railing preferably has a first open Einfädelklammer for holding the front railing on a first scaffold post and / or a second open Einfädelklammer for holding the front railing on a second scaffolding post. The first threading clip is preferably arranged or formed on the first vertical bow spar. More preferably, the second threading clip is arranged or formed on the second vertical bow spar.

The frame part in the form of a front railing is structurally further simplified when the first vertical bar spar and / or the second vertical bar spar is / are formed parallel to the central longitudinal axis of the front side railing.

The first vertical pin may be spaced further from the second vertical pin than the first vertical bow spar from the second vertical bow spar. In other words, the front side railing widens from the vertical bow bars to the vertical pins, so that in the assembled state at the bottom, it exceeds the center distance of the frame stems. As a result, the vertical pins can be inserted into the outer areas of the framework receptacles so that the inner areas of the framework receptacles remain available for connecting longitudinal bars.

In order not to have to raise the front end railing according to the invention in a single step in the construction of a scaffold to the scaffold shots, the first Vertical bow spar be connected via a cross member of the front railing with the second vertical bow spar. The cross member is thus preferably in the assembled state of the front railing below the retaining bracket. A fitter of the scaffold is thus able to turn off the end railing during construction of the scaffold in an intermediate position by placing the cross beam on a cross bar of the scaffold.

Preferably, the shortest connection between the first vertical pin and the second vertical pin on the cross member. In other words, the first vertical pin and the second vertical pin project in the manner of two legs indirectly or directly from the cross member. The end railing can thereby be lifted in the scaffolding structure with the first vertical pin ahead on the cross bar of the scaffold and then comes with the cross bar on the crossbar to lie.

In a particularly preferred embodiment of the invention, the first vertical pin - in the direction of its longitudinal axis - formed longer than the second vertical pin - in the direction of its longitudinal axis. In this way, first the first vertical pin can be inserted into the first recess and then the second vertical pin in the second recess. In other words, not both vertical pins must be introduced simultaneously into the respectively associated recesses, whereby the assembly of the front side railing is significantly facilitated.

The object according to the invention is furthermore achieved by a scaffold with an end railing described above, wherein the scaffold has a front side part with a cross bar which connects a first scaffold post to a second scaffold post, wherein the scaffold on the first scaffold post has a first stand receptacle with a first recess, in which the first vertical pin is guided and wherein the framework on the second frame stem has a second frame receptacle with a second recess into which the second vertical pin is guided.

The first recess may be formed in the form of a first through-hole. Alternatively or additionally, the second recess may be formed in the form of a second through-hole. The first frame holder can be designed in the form of a first rosette. Alternatively or additionally, the second framework receptacle may be formed in the form of a second rosette.

Preferably, the first vertical pin is further spaced from the second vertical pin than the first frame stem from the second frame stem, wherein the first frame stem is further spaced from the second frame stem than the first vertical bow spar from the second vertical bow spar. In other words, the front side railing in this case is wider in the region of its vertical pin than the inside width of the front side part and in the region of its vertical bow spars narrower than the inside width of the front side part. Particularly preferably, the axial distance between the first scaffold post and the second scaffold post exceeds the axial spacing of the vertical bow bars. As a result, the Einfädelklammern structurally particularly easy to be arranged on the vertical bracket bars.

More preferably, the framework is designed such that the cross member can be placed on the cross bar when the end railing is mounted on the front side part, wherein at the same time the first threading clip is arranged on the first scaffold post. The end railing is thereby placed during its assembly by its cross member on the cross bar and then - guided by the first Einfädelklammer - along the first scaffolding handle vertically upwards. The installation of the front side railing is thus very ergonomic and effortlessly feasible.

In a particularly preferred embodiment of the invention, the framework comprises a walk-on covering which is fastened to the crossbar, wherein the end-face railing is removable from the front side part when arranged on the crossbar pad. The covering thus does not prevent assembly or disassembly of the front side railing, whereby the front side railing can be mounted independently of the covering. In this case, the front side railing has no adjacent to the lining section.

The object according to the invention is finally achieved by a method for assembling a previously described scaffold in which a previously described end-face railing is introduced into scaffold receptacles.

The frameworks are preferably in the form of through-holes in rosettes.

In a particularly preferred embodiment of the method, the front side railing is deposited during its assembly in an intermediate step on a cross bar of the framework.

Further features and advantages of the invention will become apparent from the following detailed description of several embodiments of the invention, from the claims and from the figures of the drawing showing essential to the invention details.

The features illustrated in the drawing are not necessarily to scale and illustrated in such a way 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.
