Description

The invention relates to a front side railing for securing a front side of a walk-in scaffolding, in particular when constructing this walk-in scaffolding according to claim 1, and a scaffold with such a front side railing according to patent claim 8.

The invention further relates to a method for securing the front side of a scaffolding against people falling when assembling the scaffolding according to claim 13.

Scaffolding is used in the construction sector for various tasks. Facade scaffolding is used to design the exterior surfaces of buildings, for example to paint them. In civil engineering, scaffolding or shoring is used to bring a wide variety of building parts into position and hold them there. Such building parts can be, for example, prefabricated concrete parts, steel beams or steel structures. Furthermore, elements required for the construction of structures such as temporary structures or formwork with supporting scaffolding can be positioned. Finally, scaffolding is also used in the service or inspection area, for example to bring workers safely to the parts of the system that need to be overhauled in large process engineering plants, such as refineries. In general, the basic requirements for scaffolding are that they must be easy to transport and easy to assemble. The scaffolding is usually constructed from bottom to top. This means that the next higher floor is built from the scaffolding floor below. As long as the next higher floor is under construction, there is an increased risk of accidents due to falls, as the next higher floor is not yet completely built and does not have all the necessary safety precautions against falls. This means that the most necessary safety precautions must be installed from the floor below to the next floor before workers enter and complete the next floor. As an alternative to scaffolding-mounted safety precautions, workers can also be protected when erecting the next higher floor by wearing personal protective equipment while working on the still unsecured, next higher floor. However, such personal protective equipment is expensive and takes time to put on and connect to the scaffolding.

Out of DE 10 2015 206 276 A1 A safety railing is known which can be mounted from one floor to the front of the next higher floor of a scaffolding. This After assembly, the safety railing is arranged between two vertical scaffolding elements on the next higher floor. The disadvantage of this railing is that if this railing is to be removed again on the next higher garage, there is no protection against falling on the front side.

Out of EP 2 216 465 B1 A leading railing device is known that can be attached from below to the next higher floor. The disadvantage of this railing device is that it has very large dimensions and has guides and moving parts. This railing device is therefore complicated to construct and handle, as well as being difficult to produce.

Out of JPH10159323 A A railing for the front sides of scaffolding is known, which is attached to horizontal scaffolding elements of the existing scaffolding levels using hooks. For security purposes, a movable locking mechanism is provided, which must be activated when installing and dismantling the railing on the scaffolding. The handling of this railing is complicated and the length dimension of the railing is large, making it bulky to transport.

It is therefore the object of the invention to propose a solution for securing the front side of a scaffolding, which provides protection against falls at all times and which is easier to handle than the prior art.

This object of the invention is achieved by a front side railing for securing a front side of a walk-in scaffolding, according to claim 1.

The safety bracket of a front side railing according to the invention effectively prevents workers or other people who are on the corresponding level of the scaffolding from falling down by blocking the open side on the front side of a scaffolding. The safety bracket has two sections, the protective section arranged at the top when installed and the fastening section arranged underneath. The protective section is constructed in such a way that it effectively blocks the open side of the scaffolding. A U-shaped design has proven to be particularly suitable for this function, which is additionally provided with one or more holding elements within the U and is therefore closed. The fastening section is used to fasten the front railing to the scaffolding. For this purpose, the fastening section has at least two fastening elements. These two fastening elements are arranged at a distance from one another, this distance conveniently corresponding approximately to the width of the scaffolding or the distance between two vertically extending elements on the front side of the scaffolding. The fastening elements define a fastening plane with one of their surfaces. The safety bracket of the end railing according to the invention has a side which points towards this scaffolding during assembly and an opposite side which points away from the scaffolding during assembly. The outermost surfaces of the fasteners on the side facing the scaffolding during assembly define the fastening plane. The attachment level therefore represents the the outermost level of the safety bracket, which points towards the scaffolding when mounted on the scaffolding. The fastening level is an imaginary level that serves to define further features of the front railing according to the invention.

An end railing according to the invention also has two vertical pins which are intended to be connected to the scaffolding and thus serve to attach the end railing to the part of the scaffolding that has already been constructed. When the end railing is installed, the vertical pins run in the vertical direction and are arranged at a distance from the adjacent fastening elements. The connections between fastening elements and vertical pins form the fastening areas that are arranged between fastening elements and vertical pins. When installing the front railing on the scaffolding, the vertical pins are inserted into recesses that are usually horizontally oriented. After the vertical pins have been inserted into the recesses, the fastening areas rest on parts of the already constructed scaffolding. The vertical pins are arranged in the lower half of the fastening section when installed. Conveniently, the vertical pins end flush with the lower ends of the fastening elements. Due to this arrangement of the vertical pins in the lower area of the safety bracket, the end railing has a compact vertical dimension, which makes it easy to transport and easy to handle. The vertical pins of a front railing according to the invention are intended to be inserted into exceptions which are attached to the upper end of the already constructed part of the scaffolding. Railings from the prior art are partially attached to scaffolding elements that are arranged further down than the upper end of the existing floor. As a result, such railings from the prior art must be of larger dimensions in the vertical direction, which entails disadvantages due to a higher weight and larger dimensions of these railings. In a front railing according to the invention, the vertical pins are arranged outside the fastening plane and are located on the side of the fastening plane that is oriented towards the scaffolding in the assembled state. Because the vertical pins, which serve to connect to the scaffolding, are arranged outside the fastening plane, the securing bracket in the assembled state is at a distance from vertical elements of the scaffolding that already exist or are yet to be assembled. The safety bracket is therefore arranged outside the other scaffolding elements. This brings a decisive advantage This arrangement outside means that the space between two adjacent, vertical scaffolding elements on the next higher floor is free. As a result, a further, permanently installed front railing can be arranged in this room while the front side railing according to the invention protects this opening against falling. It is possible to install a front railing according to the invention and a standard railing, which then remains permanently on the scaffolding to secure the front side, parallel to one another. This means that a worker is protected against falling at all times on the front side of the scaffolding. The front railing according to the invention is only removed from the scaffolding when the standard railing is attached. The front railing can then be used again to secure the next higher floor. This means that each end face of the scaffolding only requires one end railing according to the invention during construction. The simple design of the front railing according to the invention and its ergonomic handling also ensure that workers accept the use of this railing. This ensures that the intended safety devices, in particular securing the front side of a scaffold, are adhered to in practice at all times. In the case of complicated safety railings, it is to be expected that in practice the workers will not use these safety precautions at all but, due to time pressure, will simply construct the scaffolding without securing the front side. A front railing according to the invention thus combines proper securing of the front side with acceptance by the people who are entrusted with the construction of the scaffolding.

The end railing comprises at least one guide, which is intended to secure the end railing against tilting relative to vertically extending elements of the scaffolding at least in one spatial direction, the guide being firmly connected to the protective section and having at least two legs spaced apart from one another in the horizontal direction, wherein the guide protrudes from the protective section in the direction from which the fastening plane points towards the scaffolding when mounted on the scaffolding. In this embodiment, at least one guide is provided which, in addition to the previously described vertical pins, establishes a further connection between the end railing and the scaffolding. By providing the guide, the front side railing is connected to the scaffolding in two places at different vertical heights. This provides improved protection against workers falling. The leadership occurs in connection with vertical elements of the scaffolding, in particular with vertical supports, which belong to the next higher level of the scaffolding that is under construction. The guide secures the front side railing against tilting at least in one direction.

To protect against falls, it is particularly important that the front side railing cannot tip out of the front side of the scaffolding. In addition, it is important that the front side railing cannot tilt parallel to the front side of the scaffolding. The guide has two legs spaced apart from one another, which can encompass vertically extending scaffolding elements. The guide, like the vertical pins, also protrudes from the mounting plane and is therefore arranged outside the securing bracket. This also results in the second connection point of the front side railing, namely between the guide and vertically extending scaffolding elements, that the safety bracket is positioned outside the front side of the scaffolding when the front side railing is attached to the scaffolding. This also ensures in the area of the guide that the space between two vertical elements of the scaffolding, in particular vertical posts, remains free in order to install a permanent standard railing on the front side of the scaffolding in addition to the front side railing.

Furthermore, the proposal advantageously provides that the two legs of the guide have different shapes. In this embodiment, the two legs of a guide are shaped differently. This means that the guide can be easily and safely mounted on the scaffolding without having any moving parts.

In a preferred embodiment of the proposal, it is provided that a first leg has a hook-shaped functional area and a second leg has a flat functional area, the functional areas being intended to interact with elements of the framework. The functional areas are the areas of the legs that come into contact with other scaffold elements. In this embodiment, a first leg has a hook-shaped functional area which is intended to at least partially surround a vertically extending scaffolding element, in particular a vertical handle. This hook-shaped area is designed in such a way that it engages behind a vertical handle when the front railing is assembled, so that the front railing cannot be accidentally removed from the scaffolding. The second leg is flat Functional area and forms a counter bearing to the leg with the hook-shaped functional area. When assembled, the leg with the flat functional area does not reach behind the vertical scaffolding elements.

Furthermore, it is provided that at least two guides are provided, which are arranged horizontally spaced apart from one another on the protective section when mounted on the scaffolding. In this embodiment, two guides are provided, each of which is conveniently arranged on one leg of the U-shaped safety bracket in the area of the protective section. By providing two guides, the securing of the front railing to the vertical scaffolding elements is further improved. In some cases, when constructing the next level of scaffolding, only one vertical support is present. The presence of two guides ensures that, regardless of which side the vertical support is located, a second connection between the front railing and the front side of the scaffolding is always established.

In an advantageous embodiment it is provided that the legs that have a flat functional area are at a smaller horizontal distance from one another than the legs that have a hook-shaped functional area. In this embodiment, the legs with the flat functional area are arranged further inside than the legs with the hook-shaped functional area on the protective section.

Cleverly, it is provided that in the state mounted on the scaffolding, a leg with a flat functional area of a first guide is arranged above a leg with a hook-shaped functional area and, in a second guide spaced horizontally from the first guide, a leg with a flat functional area is arranged below a leg is arranged in a hook-shaped functional area. In this embodiment of a front railing with two guides, the legs of the two guides are arranged differently in the vertical direction. On one side there is a leg with a hook-shaped functional area above a leg with a flat functional area. For the guide on the opposite side, the arrangement is exactly the other way around. This embodiment makes it possible to assemble or disassemble the front railing by a pivoting movement between two vertical supports, without moving parts are required. When the front railing is installed, the legs with the hook-shaped functional area engage behind the vertical posts and thus secure the front railing. If the end railing is then rotated for dismantling about an axis perpendicular to the fastening plane until the two legs with the flat functional area abut the vertical posts, then in this attached state the undercut of the legs with the hook-shaped functional areas to the vertical posts is eliminated and the end railing can be removed from the scaffolding. This special arrangement of the different legs means that the end railing can be separated from the vertically extending scaffolding elements or connected to them in a form-fitting manner by means of a rotary movement.

It is envisaged that the two legs with a hook-shaped functional area on their side facing away from the protective area have a clear width relative to one another, into which vertically extending elements of the framework can be inserted, this clear width being smaller than the external distance between two adjacent, vertically extending elements of the scaffolding is. In this embodiment, the scaffolding is secured in that the end regions of the legs with the hook-shaped functional area have a clear width to one another that is smaller than the external distance between two adjacent vertical posts of the scaffolding. As a result, these end areas undercut the vertical posts when assembled and the end railing is secured to the scaffolding. Due to the above-described vertically offset arrangement of the two legs with the hook-shaped functional area relative to one another, the effective distance between the end regions of these legs can be increased in the horizontal direction by rotating the end railing, which means that in this twisted state the vertically extending scaffolding elements can be inserted between the legs is possible with the hook-shaped functional area. If the front railing is then rotated back to its normal alignment, the effective distance between the two legs is reduced again to the clear width and the front side railing is positively connected to the vertical scaffolding elements.

Furthermore, it is conveniently provided that the two legs with a flat functional area have a leg distance on their side facing away from the protective area to each other, which is smaller than the internal distance between two adjacent, vertically extending elements of the framework. In this embodiment, the two legs with the flat functional area are positioned relative to one another in such a way that they can be inserted with play between two mutually adjacent vertical stems. The legs with a flat functional area, which are offset from one another in the vertical direction, serve as a stop for this rotational movement during the previously described rotational movement of the end railing, which is used for assembly and disassembly. In addition, the two legs with the flat functional area prevent the end railing mounted on the scaffold from tilting parallel to the fastening level.

Advantageously, it is provided that the surfaces of the protective section, which are oriented towards the scaffold when mounted on the scaffold, are arranged in the fastening plane. In this embodiment, the entire safety bracket is designed to be flat. Thus, the surfaces of the protective section oriented towards the framework also lie in the fastening plane, which is defined by the surfaces of the fastening elements of the fastening section facing the framework. A flat safety bar is particularly advantageous for storage. Of course, the protective section and the fastening section can also be arranged offset from one another, in which case the surface of the protective section facing the framework is not in the fastening plane.

Furthermore, the proposal advantageously provides that the entire front railing is designed to be rigid and in particular has no moving parts. It is particularly advantageous that the front railing is rigid. This means that the front railing is robust and reliable even in harsh environmental conditions on a construction site. In the case of railings with moving parts, as are known from the prior art, these moving parts can become dirty or corrode and are then no longer functional. In this case, such railings can pose a major safety risk if the railings no longer function as intended. With a rigid front railing, such wear and tear on moving parts cannot occur, which is very advantageous for longevity and safe function.

In a preferred embodiment of the proposal, it is provided that the vertical pins are essentially vertically oriented when mounted on the scaffolding and are rod-shaped. In this embodiment, the vertical pins are straight, in particular rod-shaped. Rod-shaped base materials are available in many different sizes and strengths, making the front railing easy to manufacture. By arranging the vertical pins vertically, they can be inserted particularly easily into recesses on the scaffolding. For some applications, however, it can also be advantageous to arrange the vertical pins at a slight angle to the vertical, for example in order to achieve self-centering. The vertical pins can also be designed to be curved or curved. With such curved vertical pins, the fastening element can be saved and the vertical pins can be connected directly to the fastening elements.

Furthermore, it is provided that the fastening area is arranged at a first end of the vertical pins and the opposite second end of the vertical pins is intended to be inserted into the scaffolding receptacles. In this embodiment, the upper first end of the vertical pin is flush with the fastening area, which in turn is attached to the fastening element with its side facing away from the vertical pin. The opposite second end of the vertical pin is free in space and is intended to be inserted into a scaffolding holder in order to establish a connection between the end railing and the rest of the scaffolding.

In an advantageous embodiment it is provided that the vertical pins and the areas of the fastening elements arranged adjacent thereto are arranged in parallel. In this embodiment, the vertical pins run parallel to the adjacent fastening elements. This creates a constant distance between the two parts, which is particularly advantageous for inserting the vertical pins into the scaffolding holders. The parallel fastening elements can be used as handles, so that the front railing is easy to handle.

It is cleverly provided that the vertical pins are arranged in a plane that is spaced apart and parallel to the fastening plane. In this embodiment they run Vertical pins, in particular their central axes, in a common plane, which in turn runs parallel to the fastening plane. This creates a constant distance between the vertical pin and the fastening section, which in turn ensures that the end railing is arranged parallel to the rest of the scaffolding.

In a further preferred embodiment it is provided that the vertical pins have a circular cross section, with the diameters of the vertical pins being smaller than recesses in the scaffolding receptacles. In this embodiment, the vertical pins and the recesses in the scaffold receptacles intended to accommodate them have a circular cross section. The recesses are designed to be slightly larger than the diameter of the vertical pins, so that a clearance fit is created, which enables the vertical pins to be pushed into the recesses. Of course, the cross sections of vertical pins and recesses can also have a different geometry and, for example, be rectangular or polygonal.

It is advantageously provided that the second end of the vertical pins and the end of the fastening elements pointing away from the protective section are flush with one another. In this embodiment, the fasteners end flush with the vertical pins. This ensures that there are areas of fastening elements parallel to the vertical pins that can be used as grip points when assembling the end railing on the scaffolding.

Furthermore, it is conveniently provided that a horizontal pin is arranged on the end of the fastening elements pointing away from the protective section, which points to the respective adjacent vertical pin, in particular to its second end, with a distance between the end of the horizontal pin facing away from the fastening element and the vertical pin consists. In this embodiment, two horizontal pins are provided on the front side railing, which run essentially horizontally when installed. These horizontal pins are arranged on the fastening elements and point their free end towards the vertical pins. There is a distance between the free end of the horizontal pins and the vertical pins that is greater than the distance that the recesses in the scaffolding receptacle occupy from the edge of the scaffolding receptacle. This makes it possible Insert vertical pins into the holders without the horizontal pins standing up on the scaffolding holder. However, if an attempt is made to insert the vertical pins into other openings that are not intended for fastening the end railing to the scaffolding, the horizontal pins form a stop that prevents the vertical pins from being inserted into these other openings. The horizontal pegs prevent the vertical pegs from being inserted into openings that are further apart from the edge of an element than the distance between the free end of the horizontal pegs and the vertical pegs. The horizontal pins serve to protect against incorrect attachment of the front railing to the scaffolding and thus ensure increased operational safety.

It is advantageously provided that the protective section and the fastening section are formed by one component. In this embodiment, the front side railing is particularly simple and robust. The protective section and fastening section are each part of the one-piece securing bracket. This embodiment can be produced particularly easily by bending a single tube. Of course, the protective section and fastening section can also initially be manufactured separately and then connected to one another, for example by plug connections, screw connections or welded connections.

Furthermore, the proposal advantageously provides that the protective section has a substantially U-shaped area and in this area at least one holding element is arranged which runs horizontally when mounted on the scaffolding. A key aspect of the end railing is to prevent workers from falling or falling off the scaffolding. To do this, the protective section must effectively block the front side of the scaffolding. A favorable embodiment of achieving this is a U-shaped protective section, in which at least one holding element is arranged in addition to completely blocking the space in the U. Of course, several holding elements can also be provided. The holding element blocks the space between the legs of the U and also serves as a handle when assembling and dismantling the front railing.

In a preferred embodiment of the proposal it is provided that the securing bracket is formed by a curved tube. This embodiment is as already described above very easy and inexpensive to produce. At the same time, a one-piece safety bracket has a high level of stability and is low in weight because connecting elements between individual parts are eliminated.

• zumindest eine Stirnseite, wobei diese Stirnseite einen Grundrahmen mit zwei horizontal voneinander beabstandete Vertikalstielen und zwei vertikal voneinander beabstandeten Horizontalriegeln, wobei die Horizontalriegel die Vertikalstiele miteinander verbinden, wobei die Horizontalriegel und die Vertikalstiele zusammen eine Außenfläche definieren und an der Stirnseite zumindest zwei Gerüstaufnahmen angeordnet sind;
• zumindest ein Stirnseitengeländer nach einem der vorhergehenden Ansprüche,
• wobei je ein Vertikalzapfen in je eine Gerüstaufnahme eingebracht ist, und wobei die Befestigungsebene deckungsgleich mit der Außenfläche ist oder in einer vom Rest des Gerüstes wegweisenden Richtung von der Außenfläche beabstandet ist. Ein erfindungsgemäßes Gerüst ist in Fig. 1 dargestellt und in der dazugehörigen Beschreibung beschrieben. Ein erfindungsgemäßes Gerüst kann verschiedene Größen aufweisen, je nachdem was für eine konkrete Anwendung benötigt wird. Dabei weist ein erfindungsgemäßes Gerüst stets zumindest einen Grundrahmen auf, der durch zwei vertikal verlaufende Vertikalstiele und zwei horizontal verlaufende Horizontalriegel gebildet wird. Ein erfindungsgemäßes Gerüst weist üblicherweise mehrere solche Grundrahmen auf, die eine zweidimensionale Grundform des Gerüst des bilden. Zumindest ein Grundrahmen ist an einer Stirnseite des Gerüstes angeordnet. Üblicherweise sind weitere Grundrahmen vorhanden, die nicht an der Stirnseite angeordnet sind sondern sich innerhalb des Gerüstes befinden. Ein an der Stirnseite angeordneter Grundrahmen bildet mit seinen nach außen orientierten Oberflächen die Außenfläche des Gerüstes auf der Stirnseite. Diese Außenfläche bildet den äußersten Abschluss des Gerüstes.

The object of the invention is also achieved by comprising a framework

• at least one end face, this end face having a base frame with two horizontally spaced vertical posts and two vertically spaced horizontal bars, the horizontal bars connecting the vertical bars with each other, the horizontal bars and the vertical bars together defining an outer surface and at least two scaffolding receptacles being arranged on the front side;
• at least one end railing according to one of the preceding claims,
• wherein a vertical pin is inserted into a respective scaffolding receptacle, and wherein the fastening plane is congruent with the outer surface or is spaced from the outer surface in a direction pointing away from the rest of the scaffolding. A framework according to the invention is in Fig. 1 shown and described in the associated description. A framework according to the invention can have different sizes, depending on what is needed for a specific application. A scaffolding according to the invention always has at least one base frame, which is formed by two vertically extending vertical posts and two horizontally extending horizontal bars. A framework according to the invention usually has several such base frames, which form a two-dimensional basic shape of the framework. At least one base frame is arranged on one end face of the scaffolding. There are usually additional base frames that are not arranged on the front side but are located inside the scaffolding. A base frame arranged on the front side forms the outer surface of the scaffolding on the front side with its outwardly oriented surfaces. This outer surface forms the outermost end of the scaffolding.

At least two scaffolding receptacles are provided on the front side, in particular on the base frame, which are used to mount the front side railing. These scaffolding holders can be firmly connected to the vertical posts or can be formed by separate components that are connected to the vertical posts when the scaffolding is being built. Furthermore, a scaffolding according to the invention comprises at least one end railing according to one of the previously described embodiments. The vertical pins of the front side railing are in the scaffolding receptacles introduced and ensure a stable hold of the front railing on the other elements of the scaffolding. Due to the shape of the front side railing, it lies outside of the other scaffolding elements, in particular outside of the vertical posts. The fastening plane of the end railing is congruent with the outer surface of the base frame or the fastening plane is on the side facing away from the rest of the scaffolding, spaced from the outer surface. And the rest of the scaffolding is understood to mean all elements of the scaffolding that are not formed by the front side railing. This arrangement of the end railing congruently or outside the outer surface leaves the space between the two vertical supports of the base frame free so that a standard railing can be attached there in addition to and parallel to the end railing if necessary. A scaffolding according to the invention thus enables the quick and safe construction of the next higher floors. The advantage of a scaffolding according to the invention is that the end railing has no moving parts and is therefore particularly robust. The front railing can therefore be stored and transported together with the other rigid scaffolding elements. Like the other scaffolding elements, the front railing is so robust that no special precautions are required for packaging and protecting the front railing during transport. A scaffolding according to the invention is therefore suitable for the harsh environmental conditions on a construction site and can therefore be transported and assembled in little time.

Furthermore, it is provided that the vertical pins are inserted into recesses in the scaffolding receptacles. In this embodiment, recesses are provided in the scaffolding receptacles into which the vertical pins are inserted. Recesses are understood to mean openings that correspond to the vertical pins. The vertical pins are conveniently simply pushed into the recesses. This means that no tools are required when assembling and dismantling the front railing, so these work steps can be carried out quickly and easily.

In an advantageous embodiment it is provided that at least one further vertical post is arranged above the base frame and the guide encompasses this vertical post in a direction parallel to the horizontal bars, whereby the end railing is secured against tilting in this direction. In this embodiment, the next highest level is used for construction Another vertical support has already been installed on this next floor. When attaching the front railing, the guide is brought into operative connection with this additional vertical post. As a result, the front side railing is connected to the additional vertical post via the guide in addition to the attachment via the vertical pins in the scaffolding holders. The front railing is connected to the scaffolding in two places at a vertical height and is therefore even better secured. The guide at least prevents the front side railing from tilting parallel to the front side. However, there is also a positive connection between the guide and the additional vertical support, which also prevents the end railing from tilting or being separated from the scaffolding in a direction perpendicular to the outer surface or end face.

It is cleverly provided that the guide has an opening on one side in a direction perpendicular to the horizontal bars, the width of which is greater than the outer diameter of the vertical stem. In this embodiment, the guide is designed so that it can be pushed over the vertical handle. This is conveniently pushed onto the vertical post after the front side railing is first rotated from the position it occupies in the assembled state. This design means that no moving parts are required on the guide, making it particularly easy to manufacture and robust.

In a further preferred embodiment it is provided that at least two vertical posts are arranged above the base frame and the end railing at least partially covers the distance between these vertical posts. In this embodiment, two further vertical posts are attached to the next highest level of the scaffolding, starting from the base frame. The front railing can also be installed easily and safely in this embodiment to secure the next higher floor.

Furthermore, it is conveniently provided that a standard railing is attached parallel to the end railing, which is arranged between two vertical posts. In this embodiment of a scaffold, a standard railing is already arranged on the front side parallel and in addition to the front side railing, which additionally protects against falls.

It is advantageously provided that the front side railing can be dismantled from the scaffolding by first lifting the front side railing in the vertical direction until the vertical pins are no longer in the scaffolding receptacles and then the front side railing is pivoted about an axis which runs at right angles to the fastening plane, whereby the positive connection between leadership and vertical style is eliminated. To dismantle the front railing from the rest of the scaffolding, in this embodiment only two movements of the front railing are required. First, the front railing is raised vertically until the vertical pins leave the recesses in the scaffolding holders. The end railing can then be twisted or pivoted in a plane parallel to the fastening plane or outer surface. The positive connection between the guide and the vertical stem is then canceled by pivoting along an axis that runs essentially at right angles to the fastening plane and/or outer surface of the end face. After this positive connection has been removed, the front side railing can simply be removed from the rest of the scaffolding in a direction perpendicular to the front side. This means that the end railing can be dismantled from the rest of the scaffolding easily and without the use of tools.

The object of the invention is further achieved by a method for securing the front side of a scaffolding against people falling while assembling the scaffolding, comprising the following steps

• Construction of a first floor of the scaffolding on the ground, the first floor having at least two base frames with two horizontally spaced vertical posts and two vertically spaced horizontal bars, the horizontal bars connecting the vertical bars with each other and a scaffolding receptacle arranged adjacent to at least one horizontal bar on each vertical bar is and the at least two base frames are vertically oriented, the scaffolding receptacles being located at the top of the base frame and the corners of a base frame each being connected to the corners of the other base frame with horizontal struts, with at least one base frame being arranged on one end face of the scaffolding and the horizontal bars and the vertical posts of this base frame together define an external surface,
• Inserting at least one tread on top of the first floor of the scaffolding, the tread being connected to the upper horizontal bars and/or the upper horizontal struts,
• Connection of at least one further vertical handle to the upper end of the base frame of the first floor arranged on the front side, the vertical handle being arranged vertically above the first floor and belonging to the second floor of the scaffolding, the connection of the further vertical handle only taking place if none of the Vertical posts of the first floor protrude into the second floor of the scaffolding,
• Attachment of a front railing, according to one of the previously described embodiments, wherein the front side railing is attached exclusively from the first floor of the scaffolding by one person and is first lifted outside the outer surface up to the height of the second floor, then the front side railing is raised vertically is pivoted to the spatial axis arranged on the outer surface and in this pivoted state a guide is guided over the at least one further vertical post in the second floor, then the end railing is pivoted back about the same spatial axis until the fastening elements are vertically aligned and this pivoting back creates a positive connection between Guide and the further vertical handle is made and then the vertical pins are inserted into the scaffolding receptacles, the front side railing being moved vertically downwards until the fastening areas stand up on the scaffolding receptacles, whereby the securing bracket of the front side railing is attached outside the outer surface of the scaffolding.

A method according to the invention serves to secure the end faces of the upper floors of a scaffolding against people falling. Scaffolding is usually erected on the ground or subgrade. Since the first floor of the scaffolding is located directly on the ground, no protection is required to prevent people from falling. Such protection is only necessary from the second floor onwards. A method according to the invention is therefore initially based on the construction of the first floor of the scaffolding arranged on the floor. This construction of the first floor is based on the state of the art. In order to achieve a stable first floor of the scaffolding, at least two base frames, each consisting of two vertical supports and two horizontal bars, are connected to one another using horizontal struts. The horizontal struts are attached at right angles to the base frames at their corners. This creates a cuboid structure made of scaffolding elements. Next up is the first floor of the A tread surface was applied to the scaffolding, which serves as a base for the second floor. At this point it is dangerous to step on the footing as the resulting second floor is not yet secured against falling. In some cases, a vertical stem from the first floor extends up to the second floor. In this case, a front railing can be connected directly to this vertical post. If there are no vertical supports on the front side of the second floor, at least one additional vertical support is first attached to the second floor, which then extends vertically upwards as an extension of the vertical support below. This additional vertical support is attached by a person who is on the first floor of the scaffolding and therefore cannot fall. It is also possible at this point to attach two more vertical posts from the first floor to the front of the second floor. A front railing according to the invention can be attached to both one and two vertical supports at the same time. A front railing is then attached to the front side of the second floor, also from the first floor. To do this, the front railing is lifted from below and first twisted or pivoted so that its guides can be pushed over the vertical post(s) on the second floor. This rotation occurs around a spatial axis that is arranged perpendicular to the outer surface or front side of the site. In this twisted state, the front railing with its guides is pushed over the vertical posts. Once the vertical posts have been inserted into the guide(s), the front side railing is rotated back around the spatial axis described. This creates a positive connection between the front railing and the vertical posts. Details of this positive connection, for which no moving parts are required, are described for the embodiments of the end railing and also apply to the method according to the invention. Once the turning back is complete, the fasteners are vertically aligned again. In this state, the guides can be moved vertically along the vertical posts. The end railing is now moved vertically downwards and its vertical pins are inserted into the scaffolding receptacles, in particular into recesses in the scaffolding receptacles. Finally, the front railing with the vertical pins inserted is moved vertically downwards until the fastening areas rest on the scaffolding holders. In this state, the front railing is firmly attached to the rest of the scaffolding. Thanks to the vertical pins inserted into the scaffolding holders, the front side railing can no longer be rotated around the spatial axis described above, which means that the positive connection between the Guides and the vertical supports cannot be lifted. The procedural features described should advantageously be carried out exactly in the order mentioned.

• Anbringen eines zweiten Vertikalstieles in der zweiten Etage des Gerüstes benachbart zu dem bereits vorhandenen weiteren Vertikalstiel, wobei dieser zweite Vertikalstiel parallel zu dem weiteren Vertikalstiel an der Stirnseite der Gerüstes angebracht wird, wobei der zweite Vertikalstiel von einer Person, die auf dem Trittbelag steht und durch das bereits angebrachte Stirnseitengeländer gegen Abstürzen gesichert ist, in einer vertikalen Bewegung durch eine zweite Führung geführt und mit dem darunter befindlichen Vertikalstiel der ersten Etage verbunden wird. In diesem weiteren bevorzugten Verfahrensschritt wird nach Anbringung des Stirnseitengeländers in der zweiten Etage ein zweiter Vertikalstiel an der Stirnseite angebracht, sofern an dieser Stelle noch kein Vertikalstiel angeordnet ist. Der zweite, weitere Vertikalstiel wird von oben zunächst durch die noch freie zweite Führung geschoben und anschließend mit dem Grundrahmen der ersten Etage verbunden. Dieser Arbeitsschritt erfolgt bereits von der zweiten Etage des Gerüstes aus, da deren Stirnseite ja bereits durch das angebrachte Stirnseitengeländer gegen Abstürzen von Personen geschützt ist. In diesem Zustand können noch weitere Elemente in der zweiten Etage des Gerüstes angebracht werden.

In a preferred embodiment, the method includes the further step

• Attaching a second vertical post on the second floor of the scaffolding adjacent to the already existing further vertical post, this second vertical post being attached parallel to the further vertical post on the front side of the scaffolding, the second vertical post being carried out by a person standing on the tread The front railing, which has already been attached, is secured against falling, is guided in a vertical movement through a second guide and is connected to the vertical post of the first floor below. In this further preferred method step, after the front side railing has been attached to the second floor, a second vertical support is attached to the front side, provided that no vertical support has yet been arranged at this point. The second, additional vertical support is first pushed from above through the still free second guide and then connected to the base frame of the first floor. This work step is carried out from the second floor of the scaffolding, as the front side is already protected against people falling by the attached front side railing. In this state, additional elements can be attached to the second floor of the scaffolding.

• Anbringen eines Standardgeländers zwischen den Vertikalstielen an der Stirnseite der zweiten Etage des Gerüstes, wobei das Standardgeländer zur dauerhaften Absicherung der Stirnseite gegen Abstürzen vorgesehen ist und wobei das Standardgeländer parallel zum Stirnseitengeländer angeordnet und befestigt wird,
• und Demontage des Stirnseitengeländers wobei dieses von einer Person, die auf dem Trittbelag der zweiten Etage steht zunächst vertikal nach oben angehoben wird bis sich die Vertikalzapfen nicht mehr in den Gerüstausnehmungen befinden und anschließend das Strirnseitengeländer um eine Raumachse senkrecht zur Außenfläche verschwenkt wird, bis kein Formschluss zwischen den Führungen und den Vertikalstielen der zweiten Etage mehr besteht und das Stirnseitengeländer abschließend von der Außenfläche weg bewegt und dadurch vom Rest des Gerüstes Gerüst getrennt wird. In weiteren bevorzugten Verfahrensschritten, die nach den zuvor beschriebenen Verfahrensschritten durchgeführt werden, wird zunächst parallel zum Stirnseitengeländer ein dauerhaft am Gerüst verbleibendes Standardgeländer an der Stirnseite montiert. Besonders günstig ist, dass dieses Standardgeländer parallel zum Stirnseitengeländer montiert werden kann. Die Person, die das Standardgeländer montiert ist somit während dessen Montage bereits durch das angebrachte Stirnseitengeländer gegen Abstürzen geschützt. Nach der Anbringung des Standardgeländers ist die Stirnseite der entsprechenden Etage durch dieses geschützt, wodurch das Stirnseitengeländer nicht mehr benötigt wird. In den nächsten Schritten wird das Stirnseitengeländer wieder entfernt, indem es zunächst vertikal nach oben bewegt wird, bis die Vertikalzapfen nicht mehr in Eingriff mit den Gerüstaufnahmen stehen. Anschließend erfolgt wieder eine Verschwenkung um die Raumachse, um den Formschluss zwischen Führungen und den Vertikalstielen aufzuheben. In diesem verschwenkten Zustand kann das Stirnseitengeländer dann entlang der beschriebenen Raumachse vom Gerüst entfernt werden. Günstigerweise wird dieses Stirnseitengeländer dann zum Absichern der nächst höher gelegenen Etage des Gerüstes verwendet.

Conveniently it is provided that the method includes the further steps

• Attaching a standard railing between the vertical posts on the front side of the second floor of the scaffolding, the standard railing being intended to permanently secure the front side against falls and the standard railing being arranged and fastened parallel to the front side railing,
• and dismantling the front railing, which is first lifted vertically upwards by a person standing on the tread of the second floor until the vertical pins are no longer in the scaffolding recesses and then the front side railing is pivoted about a spatial axis perpendicular to the outer surface until there is no positive connection between the guides and the vertical posts of the second floor and the end railing is finally moved away from the outer surface and is thereby separated from the rest of the scaffolding. In further preferred process steps, which follow those described above If the process steps are carried out, a standard railing that remains permanently on the scaffold is first installed on the front side parallel to the front side railing. What is particularly convenient is that this standard railing can be installed parallel to the front railing. The person who assembles the standard railing is therefore already protected against falling by the attached front railing during its assembly. After the standard railing has been attached, the front side of the corresponding floor is protected by it, meaning that the front side railing is no longer required. In the next steps, the front railing is removed again by first moving it vertically upwards until the vertical pins are no longer in engagement with the scaffolding holders. This is then followed by pivoting again around the spatial axis in order to eliminate the positive connection between the guides and the vertical supports. In this pivoted state, the front side railing can then be removed from the scaffolding along the spatial axis described. This end railing is then conveniently used to secure the next higher level of the scaffolding.

Furthermore, it is provided that, starting from the second floor of the scaffolding, the steps claimed in the preceding claims starting from the first floor for attaching the end railing, attaching the vertical posts, attaching the standard railing and dismantling the end railing are carried out for all in the vertical direction be repeated at the top of the following floors of the scaffolding. The use or method for securing the front side of a scaffolding for the second floor of this scaffolding was previously described. Of course, the method steps described can also be carried out for all other floors of the scaffolding in order to secure the next higher floor during construction against people falling on the front side. It is particularly advantageous that only one front side railing is required per front side of the scaffolding, which is always attached in advance to the next higher floor. After the parallel installation of a standard railing, this front railing can then be used again for the next floor. For securing according to the method described, only a small number of end railings are required, which means that little effort is required for the provision and transport of the scaffolding elements used for safety.

In the figures, the same elements are given the same reference numbers. In general, the properties of an element that are described for one figure also apply to the other figures.

Fig. 1 shows a perspective view of an embodiment of a scaffolding 100 according to the invention. The scaffolding 100 shown can be used, for example, as a facade scaffolding, without limiting its applicability to a facade scaffolding. The framework 100 has vertically extending, horizontally extending and diagonally extending elements. The scaffolding 100 has four levels that people can walk on. The framework 100 can of course also include a different number of levels. Vertically extending elements of the framework are, for example, the vertical posts 102, which run between vertically adjacent planes. In the simplest case, these vertical posts 102 consist of cylindrical metal tubes, which have interfaces at their ends for connection to other scaffolding elements. Of course, the vertical posts 102 can also be different be designed, for example have a rectangular cross section or consist of another active ingredient, for example bamboo.

Horizontally extending horizontal bars 103 are arranged between the vertically extending vertical posts 102. Two adjacently arranged vertical styles 102 each form a base frame 106 with two horizontal bars 103 arranged parallel to one another and at right angles to the vertical posts 102. Such a base frame 106 is shown symbolically hatched at the bottom left. Base frames 106 can be found in many other places in the framework 100 and are a two-dimensional basic unit of this framework 100. The narrow side of the framework pointing to the front left is referred to as the front side of the framework 100. The base frame 106, shown hatched, is part of the front left-facing end face of the scaffolding 100. The long side of the scaffolding 100 runs at right angles to the end face. A plurality of horizontal struts 109 run horizontally in the direction of the long side. These horizontal struts 109 connect the direction of the base frame 106 adjacent to the long side with one another.

Scaffolding receptacles 104 are arranged on at least some of the vertical posts 102, which are shown in detail in Fig. 6 to Fig. 8 you can see. These scaffolding receptacles 104 are interfaces for connecting different scaffolding elements to one another. The scaffolding receptacles 104 can be used, for example, to connect the vertical posts 102 with horizontal bars 103 or horizontal struts 109. It is also possible to design the scaffolding receptacles 104 as separate components, i.e. not as components of the vertical posts 102. In the area of the scaffolding 100 that is oriented towards the left front, diagonally extending elements are arranged between two horizontal struts 109, which serve to additionally stabilize the scaffolding 100. However, these diagonal elements are not always absolutely necessary. The base frames 106 arranged on the front side form an outer surface 105 with their outwardly oriented surface, i.e. with the surface which forms the temporal end of the scaffold 100 in a plan view of the long side of the scaffold 100. This outer surface 105 is an imaginary auxiliary plane the outer boundary of the framework 100 is defined on the front side. All elements that are located on the side of the outer surface 105 facing away from the framework are referred to as outside the framework. So that the scaffolding 100 can be safely walked on by people to work, the top three floors each have treads 112. These tread coverings 112 are each mounted in the horizontally extending frame between two horizontal struts 109 and two horizontal bars 103, for example in these frames hung. To prevent workers from accidentally falling off the scaffolding at higher levels, railings are installed. In the longitudinal direction these are the longitudinal railings 111 and the standard railings 110 on the end faces of the scaffolding. The longitudinal railings 111 and the standard railings 110 are firmly and permanently mounted on the scaffolding 100 and remain there while the work is being carried out.

On the top floor of the scaffolding 100, end railings 1 are attached to both sides. When building the scaffolding 100 in the vertical direction upwards, the next floor is built from the floor below. This state of the structure of the next floor is particularly critical since in this state not all security elements have been arranged on the next floor. The front railing 1 is suitable for being mounted from the floor below to the next floor above, without the worker having to access the floor above. If the worker then enters the next higher floor during further construction, the front side is already secured against falling down by the front side railing 1. The front railing 1 is therefore designed in such a way that it can be installed very easily and quickly from the floor below. While the front railing 1 is attached to the top floor of the scaffolding 100, the other elements of the top floor are attached and fastened. To permanently protect the top floor from falling, a standard railing 110 is finally attached to the front sides. This standard railing 110 can be attached in parallel, within the front railing 1, while the front railing 1 still remains on the scaffolding 100. This condition is in detail Fig. 8 to see. Finally, the front railing 1 can be removed from the scaffolding again, and the front side of the corresponding floor is then secured by the standard railing 110. The front railing 1 can then be used to build the next floor above. Of course, a front side railing 1 can also be used to permanently secure the front side of a floor of the scaffolding 100.

Fig. 2 shows a perspective view of an embodiment of a front side railing 1. The front side railing 1 is shown here without scaffolding 100. The largest component of the front railing 1 is the safety bracket 2. The safety bracket 2 is formed here by a bent steel tube. The securing bracket 2 has two sections, the upwardly oriented protective section 21 and the downwardly oriented fastening section 22. The The protective section 21 arranged at the top is essentially U-shaped and forms the part of the end railing 1, which is intended to protect a worker from falling from the scaffolding 100. This U-shaped area blocks the front side of the scaffolding 100 when the front side railing 1 is mounted on it. A holding element 211 is additionally arranged between the two legs of the U-shaped region of the protective section 21. This holding element 211 additionally blocks the area between the legs of the protective section 21. In the case shown, the holding element 211 is formed by a welded-in tube. Of course, the holding element 211 can also be fastened differently, for example by a plug connection or by screw connections. At the same time, the holding element 211 serves as a grip point at which the worker can comfortably hold the end railing 1 during assembly or disassembly on the scaffolding 100. As shown, the protective section 21 can consist of two parts that are firmly connected to one another. Alternatively, the protective section 21 can also be composed of several parts, which are always firmly connected to one another in the assembled state. The fastening section 22 is arranged below the protective section 21. This fastening section 22 serves to fasten the securing bracket 2 to the frame 100. In the illustrated embodiment, the fastening section 22 comprises two vertically oriented fastening elements 221. These fastening elements 221 are designed here as straight, cylindrical tubes. The distance between the two fastening elements 221 is wider than the distance between the two legs of the annular region of the protective section 21. This means that the securing bracket 2 is wider in the fastening section 22 than in the protective section 21. The distance between the two fastening elements 221 essentially corresponds the distance between two adjacent vertical posts 102 of the scaffolding 100. The width of the protective section 21 is smaller than the distance between two adjacent vertical posts 102 of the scaffolding 100. The two fastening elements 221 are each connected to the two legs of the U via an S-shaped pipe section. shaped protective section 21 connected. Conveniently, the entire safety bracket 2 is bent from a single tube. The fastening section 22 and the protective section 21 are therefore made from a single component and merge into one another. The fasteners 221 can also have a linear shape other than the one shown. The fastening elements can, for example, be curved or S-shaped. The fastening level 222 is an imaginary auxiliary level and in Fig. 2 shown as a rectangle. The fastening level 222 is defined by the in Fig. 2 to the right rear oriented surface of the two fastening elements 221 is defined. The fastening plane 222 rests on the surface of the two fastening elements 221, which is oriented to the rear to the right, and thus symbolizes the boundary of the fastening section 22 facing the frame 100. In the lower half of the two fastening elements 221, the vertical pins 3, which are oriented to the rear to the right, are attached, which are above each a fastening area 31 is connected to the fastening elements 221. The vertical pins 3 and the fastening areas 31 extend beyond the fastening plane 222 to the rear right. The vertical pins 3 are thus arranged on the side facing the frame 100 outside the fastening plane 222. The fastening areas 31 with the vertical pins 3 attached to them can be attached at right angles to the fastening plane 222. In the case shown, however, the two fastening areas 31 extend at an angle towards one another, so that they are oriented towards the respective opposite fastening element and have an angle to the fastening plane 222 that is smaller than 90 °. The vertical pins 3 are straight and cylindrical here and are made of solid steel. Of course, the vertical pins 3 can also have a different cross section or be formed by a tube. The fastening areas 31 are designed here as flat iron and are therefore cuboid. The fastening areas 31 are welded to the fastening elements 221; on the opposite side of the fastening areas 31, the vertical pins 3 are welded to the fastening areas 31. Of course, vertical pin 3 and fastening area 31 can also be attached to one another and to the fastening element 221 via other connections, for example a screw connection. In the case shown, the lower ends of the vertical pins 3 end flush with the lower ends of the fastening elements 221. The vertical pins 3 and the fastening elements 221 run parallel to one another. A horizontal pin 5 is attached to the lower end of the fastening elements 221, in Fig. 2 A horizontal pin 5 can only be seen on the left side. The horizontal pins 5 are attached at the same height as the downward-pointing end of the vertical pins 3 and point towards the vertical pins 3. There is a distance between the ends of the horizontal pins 5 pointing away from the fastening elements 221 and the lower ends of the vertical pins 3. When assembling the end railing 1 on the scaffolding 100, the vertical pins 3 are inserted into the scaffolding receptacles 104. The horizontal pins 5 ensure that the vertical pins 3 are actually inserted into the scaffolding receptacles 104 provided for this purpose and are not improperly connected to other scaffolding elements. The Horizontal pins 5 reduce the distance between the lower end of the fastening elements 221 and the lower end of the vertical pins 3. If an attempt is made to insert the vertical pins 3 into scaffolding elements that are not intended for this purpose, the horizontal pins 5 stand on these scaffolding elements that are not intended for this purpose and cause the vertical pins to be inserted 3 impossible. The horizontal pins 5 here consist of flat iron or flat steel and are welded to the lower ends of the fastening elements 221.

Viewed in the vertical direction, two guides 4 are arranged approximately in the middle of the protective section 21. These guides 4 each include two legs 41, which are permanently and firmly attached to the legs of the U-shaped area of the protective section. The two legs 41 of a guide 4 have different shapes, which in Fig. 2 can be seen particularly well in the forward, right-oriented leadership 4. Further details about the tours are in Fig. 3 to Fig. 5 to see. The two legs 41 are arranged one above the other in the vertical direction. The upper leg 41 has a flat functional surface, the lower leg 41 has a hook-shaped functional surface. The guide 4 is intended to come into operative connection with vertically extending elements of the scaffolding 100. Through the guide 4, a further connection to the scaffolding 100 is established when the end railing 1 is mounted on the scaffolding 100. The end railing 1 is therefore positively connected to the scaffolding on the one hand by the vertical pins 3 inserted into the scaffolding receptacles 104 and on the other hand by the guide(s) 4. Should a worker fall against the front railing 1, it is connected to the scaffolding by vertical pins 3 and guides 4, whereby the front railing 1 is firmly and securely attached to the other scaffolding elements 100. With the vertical pins 3, the front side railing 1 is connected at its lower end to the scaffolding 100. A further connection is made further up via the guides 4, here approximately at the end of the uppermost third of the front side railing 1. In the embodiment shown, the front side railing 1 is mounted thus connected at four points to other elements of the scaffolding 100 and thus securely secured. The guides 4 also protrude to the rear right beyond the fastening level 222 shown below. As a result, the safety bracket 2 is positioned outside the other scaffolding elements when the end railing 1 is mounted on the scaffolding 100. The legs 41 of the two guides 4 on the right and left of the front railing 1 are arranged in reverse. On the right side, the leg 41 with the hook-shaped functional area is attached below the leg 41 with the flat functional area. On the On the opposite left side the arrangement is exactly the opposite. This mutually inverted arrangement of the legs 41 enables a simple and yet safe installation of the end railing 1. As in particular in Fig. 5 can be seen, the clear width between the rear-oriented ends of the legs 41 with the hook-shaped functional area is smaller than the external distance between two adjacent vertically extending elements of the framework. In the in Fig. 2 In the illustrated orientation of the front railing, the rear-facing ends of the legs 41 with the hook-shaped functional areas undercut the vertically extending scaffolding elements, in particular vertical posts 102. The front side railing 1 can thus be in the in Fig. 2 The orientation shown cannot be mounted on or removed from the frame 100 in a direction perpendicular to the mounting plane 222. For assembly or disassembly, the front railing 1 is pivoted about an axis perpendicular to the mounting plane 222. This increases the effective clear width between the legs 41 and the end railing 1 can be mounted on or removed from the scaffolding 100. The legs 41 are made here of flat metal, in particular iron or steel, and are welded to the protective section 21. Of course, the guides 4 can also be made of other material and can be connected to the safety bracket 2, for example by screw connections.

Fig. 3 shows a frontal view of the front railing 1 Fig. 2 . Fig. 3 shows the front railing 1 Fig. 2 viewed from the front left. Alternatively, in Fig. 3 the areas of two vertical supports 102 of the framework 100 are shown in dashed lines, which come into operative connection with the guides 4. At the lower end of the fastening section 22, the two vertical pins 3 can be seen, which in this view are oriented inwards from the fastening elements 221. On the protective section 21, a guide 4, each with two legs 41, is arranged on the right and left. On the right side, the lower, longer leg 41 is provided with a hook-shaped functional area. The leg 41 arranged above has a flat functional area. On the left side, the arrangement of the two legs 41 is exactly the opposite. In the case shown, the front railing 1 is connected to the two areas of the vertical posts 102 shown. As in Fig. 5 can be seen, the two legs 41 with the hook-shaped functional areas undercut the two vertical posts 102 in the case shown. The end railing 1 is therefore positively connected to the vertical posts 102 in a direction out of the plane of the drawing and cannot be dismantled in this direction without further movements. If the front railing 1 is now to be dismantled from the scaffolding, it is rotated counterclockwise according to the symbolic arrow 111. Due to the reversed and spaced arrangement of the legs 41, after such a rotational movement, the legs 41 with the hook-shaped functional area are no longer in engagement with the vertical posts 102 and the end railing 1 can move in a direction out of the plane of the drawing after a rotational movement or interlocking according to the arrow 111 can be removed from the vertical stems 102. This design of the guides 4 ensures, on the one hand, that the end railing 1 is securely held on the scaffolding 100 in the assembled state and, on the other hand, the end railing 1 can be mounted and dismantled on the scaffolding 100 by simply pivoting. What is particularly advantageous is that the entire front railing 1 is rigidly constructed and has no moving parts. This makes the front railing 1 robust and inexpensive to manufacture.

Fig. 4 shows a side view of the front railing Fig. 2 . In Fig. 2 no elements of the framework 100 are shown. Viewed from the side, the fastening level 222 appears like a line and is symbolized by a dashed line below the front railing 1. It can be clearly seen that the right-oriented surface of the fastening elements 221 defines the fastening plane 222. In the embodiment shown, the entire securing bracket 2 is flat, so that the right-facing surface of the protective section 21 is also located in the fastening plane 22. The elements guides 4, vertical pins 3, fastening areas 31 and horizontal pins 5 protrude to the right beyond the fastening level 222.

Fig. 5 shows a top view of the front railing 1 Fig. 2 . This view also includes the vertical posts 102, which are already closed Fig. 3 have been shown in dashed lines for better understanding. These two vertical stems 102 have an external distance 502 from one another. The two legs 41 with the hook-shaped functional area have a clear width 501 on their upwardly oriented side. It is easy to see that the outside distance 502 is larger here than the inside width 501. As a result, the legs 41 with the hook-shaped functional area of the front side railing 1 undercut the two vertical posts 102. This means that a movement of the front side railing 1 in the direction of arrow 504 is not possible, there is a form fit. For this reason, the arrow 504 is symbolically crossed out here. The two upwardly facing ends of the legs with the flat functional area define a leg distance 503. This leg distance 503 is smaller than the inner distance between the two vertical stems 102. The vertical stems 102 are each located between a leg 41 with a hook-shaped functional area and a leg with a level functional area. In the case shown, the guides 4 establish a positive connection with the vertical posts 102 of the scaffolding 100. In order to be able to assemble or disassemble the front railing 1 in the direction of arrow 504, a rotation or pivoting movement must first be carried out in accordance with the in Fig. 3 arrow 111 can be carried out. After this rotation or pivoting movement has been carried out, there is no longer any positive connection between the guides 4 and the vertical supports 102 and the end railing 1 can be moved in the direction of arrow 504.

Fig. 6 shows a perspective detailed view of a scaffolding 100 with a front side railing 1. In Fig. 6 only part of a scaffold 100 can be seen. Several vertical struts 102 run vertically. A horizontal bar 103 runs horizontally on the front side. Two horizontal struts 109 run to the rear to the right, of which only the front one can be seen. A tread 112 is inserted between the horizontal bar 103 and the horizontal struts 109, which here consists of two parts. The two vertical bars 102 arranged below the horizontal bar 103, the horizontal bar 103 shown, the two horizontal struts 109 and the two-part tread covering 112 belong to the first floor of the scaffolding 100, which is built on the ground or subsoil. The two vertical posts 102 attached above the horizontal bar 103 belong to the second floor of the scaffolding 100. Scaffolding receptacles 104 are arranged on the vertical posts 102, which are designed here in a rosette shape. These scaffolding receptacles are used to connect abutting scaffolding elements. The scaffolding receptacles 104 are attached to the upper end of the base frame 106 arranged on the end face 101. Here the horizontal bar 3 and the horizontal struts 109 are suspended in the scaffolding receptacles 104. In the case shown, the scaffolding receptacles 104 are firmly connected to the vertical posts 102. However, it is also possible to design the scaffolding receptacles 104 as separate components which, for example, are plugged or screwed together with the vertical supports 102. In the case shown, two vertical posts 102 of the second floor run upwards above the first floor shown, above the tread surface 112. At the However, when constructing the scaffolding 100, it can also happen that above the top floor there is initially only one vertical support 102, which belongs to the second floor. A front railing 1 is attached to the front of the second floor. This is inserted with its vertical pins 3 into recesses 1041 of the scaffolding receptacles 104. Further up, the two guides 4 form a positive connection with the vertical posts 102, as before, for example Fig. 5 was described. The end railing 1 is thus connected to the other elements of the scaffolding 100 at two points in the vertical direction. Through this double connection, on the one hand through the vertical pins 3 in the recesses 1041 and on the other hand through the guides 4, which enclose the upwardly extending vertical posts 102, the end railing 1 is securely attached to the end face of the scaffolding 100 and thus effectively prevents falls. In order to be able to dismantle the end railing 1 from the scaffolding 100, starting from the case shown, the end railing 1 is first lifted vertically upwards according to arrow A until the vertical pins 3 leave the recesses 1041. The guides 4 can be moved along the vertical posts 102 during this vertical movement. As soon as the vertical pins 3 are no longer in the recesses 1041, the end railing 1 can be rotated or pivoted according to arrow B. The arrow B is shown in a plane parallel to the outer surface 105. A rotation or pivoting of the end railing 1 thus takes place about a spatial axis that is perpendicular to the outer surface 105. The spatial axis is an imaginary axis to precisely describe the pivoting or twisting. Due to the rotation, the positive connection between the guides 4 and the vertical supports 102 is canceled and the front side railing can be dismantled towards the front side. The end railing 1 is installed in exactly the opposite way. First, one or both guides 4 (depending on the structural state of the scaffolding 100) are pushed over the vertical support(s) 102 in a twisted position. The end railing 1 is then inserted into the in Fig. 6 The orientation shown is turned back around the previously defined spatial axis and the vertical pins 3 are inserted into the recesses 1041 in a vertical downward movement. After inserting the vertical pins 3 into the recesses 1041, twisting according to arrow B is no longer possible. Thus, the positive connection between guides 4 and vertical supports 102 cannot be canceled without a previous vertical movement. This means that the front railing 1 cannot be accidentally separated from the rest of the scaffolding 100. The described installation of the front side railing 1 is also easily possible from one floor lower. To do this, the worker simply grabs the fastening elements 221 and mounts the front railing 1 from below next higher floor. It is particularly advantageous that the front railing 1 has a low weight and is therefore easy to lift.

Fig. 7 shows a perspective detailed view of a scaffolding 100 with a standard railing 110. In Fig. 7 no end railing 1 is installed. A standard railing 110 is installed between two vertical posts 102. Such a standard railing 110 is used to permanently secure the front side of the scaffolding 100. The standard railing 110 has the disadvantage that it is very difficult to attach it to the front side from the floor below.

Fig. 8 shows a perspective detailed view of a scaffolding 100 with a standard railing 110 and with a front side railing 1. In Fig. 8 Both a standard railing 110 and a front side railing 1 are installed parallel to each other in the second floor of the scaffolding 100. Here a particular advantage of the front railing 1 becomes clear: the front side railing 1 has its securing bracket 2 arranged outside the outer surface 105 of the scaffolding 100 defined by the vertical posts 102. Thus, the space between the vertical posts 102 is free despite the front side railing 1 being installed, so that a standard railing 110 can be used in parallel at this point. When constructing the scaffolding 100, a front railing 1 is first assembled from the floor below as described. The floor above is then built up and a standard railing 110 is also attached parallel to the front railing 1. The front side is then secured by the standard railing 110 and the front side railing 1 can be dismantled as described and used to build the next higher floor.
