Description

The invention relates to an end railing for securing an end face of a scaffolding that can be walked on, in particular when building this accessible scaffolding according to claim 1 and a scaffolding with such an end side railing according to claim 11. The invention also relates to a method for protecting the end face of a scaffolding against falling of people when building the scaffolding according to claim 16.

Scaffolding is used in the construction sector for various tasks. Façade 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 various structural parts into position and to hold them there. Such structural parts can be, for example, precast concrete parts, steel girders or steel structures. Furthermore, elements required for the erection of structures, such as temporary structures or formwork, can be positioned with shoring. After all, scaffolding is also used in the service or inspection area, for example to safely bring workers in large process engineering plants, such as refineries, to the plant parts to be overhauled. In general, the basic requirements for scaffolding are that they must be easy to transport and easy to assemble. The scaffolding is usually built from the bottom up. This means that the next level up is built from the level of the scaffolding 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 has not yet been completely built and does not have all the necessary safety precautions against falls. Thus, the most necessary safety precautions have to be installed from the floor below to the next higher floor before workers can enter the next higher floor and finish. As an alternative to the safety precautions mounted on the scaffolding, the workers can also be secured by personal protective equipment when setting up the next higher floor while working on the unsecured, next higher floor. Such personal protective equipment is expensive and has to be put on and connected to the scaffolding in a time-consuming manner.

Out DE 10 2015 206 276 A1 a safety railing is known, which can be mounted from a floor on the face 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 level. The disadvantage of this railing is that if this railing is then to be removed again on the next higher garage, in the meantime there is no protection against falling on the front side.

Out EP 2 216 465 B1 a leading railing device is known which can be attached from below to the next higher floor. The disadvantage of this railing device is that it has very large dimensions and guides and moving parts. This railing device is thus of a complicated construction and handling, and is complex to manufacture.

Out JP H10159323 A a railing for end faces of scaffolding is known, which is attached to horizontally extending scaffolding elements of the existing scaffolding floors by hooks. A movable locking mechanism is provided for securing, which must be actuated when assembling and disassembling the railing on the scaffolding. The handling of this railing is complicated and the length dimension of the railing is large, so that it is bulky to transport.

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

• zumindest zwei Vertikalzapfen welche dazu vorgesehen sind, in jeweils eine Gerüstaufnahme des Gerüstes eingeschoben zu werden und die jeweils beabstandet zu einem Befestigungselement angeordnet sind und über einen Befestigungsbereich mit jeweils einem Befestigungselement fest verbunden sind,

wobei die Vertikalzapfen an der vom Schutzabschnitt weg weisenden Seite der Befestigungselemente in der vom Schutzabschnitt weg weisenden Hälfte der Länge der Befestigungselemente angeordnet sind und
wobei die Vertikalzapfen außerhalb der Befestigungsebene in der Richtung zur Befestigungsebene angeordnet sind, die beim an dem Gerüst montierten Zustand zum Gerüst hin weist, wodurch der Schutzabschnitt bei in die Gerüstaufnahmen eingeführten Vertikalzapfen außerhalb von vertikal verlaufenden Elementen des Gerüstes angeordnet ist.This object of the invention is achieved by a front side railing for securing a front side of a walk-on scaffolding, in particular during the construction of this walk-on scaffolding, comprising a safety bracket which has a protective section which is provided to prevent a person from falling from a walk-on scaffolding and which furthermore has a fastening section which is provided to connect the end railing to the scaffolding and which is arranged below the protective section and connected to it, wherein the fastening section has at least two spaced apart, essentially vertical fastening elements and the fastening elements with at least one part their, when mounted on the scaffold state towards the scaffold oriented surfaces define a fastening plane that is essentially vertically oriented in the assembled state on the frame;

• at least two vertical pins which are intended to be pushed into a scaffold receptacle of the scaffold and which are each arranged at a distance from a fastening element and are firmly connected to a fastening element via a fastening area,

wherein the vertical pins are arranged on the side of the fastening elements facing away from the protective section in the half of the length of the fastening elements pointing away from the protective section, and
wherein the vertical pegs are arranged outside the fastening plane in the direction to the fastening plane, which points towards the scaffolding when mounted on the scaffolding, whereby the protective section is arranged outside vertically extending elements of the scaffolding when the vertical pegs are inserted into the scaffolding receptacles.

The securing bracket of an end 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 securing bracket has two sections, the protective section arranged at the top in the installed state and the fastening section arranged below. The protective section is constructed in such a way that it effectively blocks the open side of the framework. A U-shaped configuration has proven to be particularly suitable for this function, which is additionally provided with one or more holding elements within the U and is thus closed. The fastening section is used to fasten the face 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 advantageously corresponding approximately to the width of the scaffolding or the distance between two vertically extending elements of the end face of the scaffolding. The fastening elements define a fastening plane with one of their surfaces. The securing bracket of the end-face railing according to the invention has one side which, when mounted on a scaffold, points to this scaffold and an opposite side, which faces away from the scaffold when mounted. The outermost surfaces of the fastening elements on the side that faces the scaffolding during assembly define the fastening plane. The mounting level thus represents the represents the outermost level of the securing bracket, which points to the scaffolding when mounted on the scaffolding. The fastening plane is an imaginary plane which is used to define further features of the end 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 built up. In the installed state of the end railing, 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 pegs form the fastening areas that are arranged between fastening elements and vertical pegs. When assembling the face railing on the scaffolding, the vertical pins are inserted into recesses, which are usually oriented horizontally. After the vertical pins have been inserted into the recesses, the fastening areas rest on parts of the framework that has already been set up. The vertical pegs are arranged in the lower half of the fastening section of the when installed. The vertical pegs advantageously end flush with the lower ends of the fastening elements. As a result of this arrangement of the vertical pins in the lower area of the securing bracket, the front side railing has compact vertical dimensions, which means that it is easy to transport and easy to use. The vertical pins of an end railing according to the invention are intended to be introduced into exceptions that are attached to the upper end of the part of the scaffolding that has already been built up. Railings from the prior art are partially attached to scaffolding elements that are arranged further down than the upper end of the already existing floor. As a result, such railings from the prior art have to be dimensioned larger in the vertical direction, which has disadvantages due to a higher weight and larger dimensions of these railings. In the case of an end railing according to the invention, the vertical pins are arranged outside the fastening plane and are located on the side of the fastening plane which, in the assembled state, is oriented towards the scaffolding. Because the vertical pins, which are used to connect to the scaffolding, are arranged outside the fastening plane, the securing bracket in the assembled state is at a distance from existing or yet to be assembled vertical elements of the scaffolding. The safety bracket is thus arranged outside the other scaffold elements. This has a decisive advantage by this arrangement outside the space between two adjacent, vertically running scaffolding elements on the next higher floor is free. As a result, a further, permanently installed front railing can be arranged in this space while the front side railing according to the invention protects this opening against falling. It is possible to install a front side 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. As a result, a worker is secured against falling on the face of the scaffolding at all times. The end railing according to the invention is only removed from the scaffolding when the standard railing is attached. The front side railing can then be used again in advance to secure the next higher floor. Thus, each end face of the scaffolding only needs one end face railing according to the invention during construction. The simple construction of the end railing according to the invention and its ergonomic manageability also give workers acceptance of the use of this railing. This ensures that the safety devices provided, in particular securing the end face of a scaffolding, are also adhered to in practice at all times. In the case of complex safety railings, it is to be expected that the workers in practice will not use these safety precautions at all, but rather simply set up the scaffolding without securing the front side due to time pressure. A front side railing according to the invention thus combines a prescribed securing of the front side with acceptance by the people who are entrusted with the construction of the scaffolding.

In a preferred embodiment it is provided that the front side railing comprises at least one guide, which is provided to secure the front side railing at least in one spatial direction against tilting relative to vertically extending elements of the scaffolding, the guide being firmly connected to the protective section and at least two from each other has legs spaced apart in the horizontal direction, the guide protruding from the protective section in the direction out of that of the fastening plane which, when it is mounted on the scaffold, points towards the scaffold. In this embodiment, at least one guide is provided which, in addition to the vertical pins described above, establishes a further connection between the face railing and the scaffolding. By providing the guide, the face railing is connected to the scaffolding at two points at different vertical heights. This provides improved protection against workers falling. The leadership occurs in connection with vertically extending elements of the scaffolding, in particular with vertical posts that 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 prevent falls, it is particularly important that the front side railing cannot tilt out of the front side of the scaffolding. In addition, it is important that the face railing cannot tilt parallel to the face of the scaffolding. The guide has two legs which are spaced apart from one another and which can encompass vertically extending framework elements. The guide, like the vertical pins, also protrudes from the fastening plane and is therefore arranged outside the securing bracket. As a result, at the second connection point of the end railing, namely between the guide and vertically extending scaffolding elements, the securing bracket is positioned outside the end face of the scaffolding when the end railing is attached to the scaffolding. This also ensures that the space between two vertically extending elements of the scaffolding, in particular vertical posts, remains free in the area of the guide so that a permanent standard railing can be installed on the front of the scaffolding in addition to the face 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. In this way it can be achieved that the guide is easily and securely mounted on the scaffolding without it having moving parts for this purpose.

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 framework elements. In this embodiment, a first leg has a hook-shaped functional area which is provided to at least partially encompass a vertically extending framework element, in particular a vertical post. This hook-shaped area is designed in such a way that it engages behind a vertical post in the assembled state of the front side railing, so that the front side railing cannot be accidentally removed from the scaffolding. The second leg has a flat one Functional area and forms a counter-bearing to the leg with the hook-shaped functional area. The leg with the flat functional area does not engage behind the vertically extending framework elements in the assembled state.

Furthermore, it is provided that at least two guides are provided which, when they are mounted on the scaffolding, are arranged horizontally spaced from one another on the protective section. In this embodiment, two guides are provided which are each 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 end railing on the vertically extending scaffolding elements is further improved. In some cases, when building the next higher level of a scaffolding, there is only one vertical post. The presence of two guides ensures that, regardless of the side on which this one vertical post is located, a second connection between the front side 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 have 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 mounted state 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 the case of a second guide that is horizontally spaced from the first guide, a leg with a flat functional area below a leg with a hook-shaped functional area is arranged. In this embodiment of an end 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. In the case of the guide on the opposite side, the arrangement is exactly the other way around. This embodiment makes it possible to mount or dismantle the front side railing by a pivoting movement between two vertical posts without moving parts are required for this. In the assembled state of the end railing, the legs with the hook-shaped functional area engage behind the vertical standards and thus secure the end railing. If the front side railing is then rotated about an axis perpendicular to the fastening plane for dismantling, until the two legs with the flat functional area abut the vertical posts, then in this hinged state the undercut of the legs with the hook-shaped functional areas to the vertical posts is canceled and the front side railing is canceled can be removed from the scaffolding. This special arrangement of the different legs thus has the effect that the front side railing can be separated from the vertically extending scaffolding elements or connected to them in a form-fitting manner by a rotary movement.

In a further preferred embodiment, it is provided that the two legs with a hook-shaped functional area on their side facing away from the protection area have a clear width to one another, into which vertically running elements of the scaffolding can be introduced, this clear width being smaller than the outer distance between two adjacent, vertically extending elements of the framework is. In this embodiment, the scaffolding is secured in that the end areas of the legs with the hook-shaped functional area have a clear width to one another which is less than the outer distance between two adjacent vertical posts of the scaffolding. As a result, these end areas undercut the vertical standards in the assembled state and the front side railing is secured to the scaffolding. Due to the above-described vertically offset arrangement of the two legs with the hook-shaped functional area to one another, however, the effective distance between the end areas of these legs can be increased in the horizontal direction by a rotary movement of the end areas of these legs, whereby in this twisted state the vertically extending framework elements can be inserted between the legs is possible with the hook-shaped functional area. If the front side railing is then turned back into its normal orientation, the effective distance between the two legs is reduced again to the clear width and the front side railing is positively connected to the vertically extending scaffolding elements.

Furthermore, it is advantageously provided that the two legs with a flat functional area on their side facing away from the protection area have a leg spacing have to each other, which is smaller than the inner distance between two mutually adjacent, vertically extending elements of the frame. 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 vertical posts that are adjacent to one another. The legs, which are offset from one another in the vertical direction and have a flat functional area, serve as a stop for this rotary movement during the previously described rotary movement of the front side railing, which is used for assembly and disassembly. In addition, the two legs with the flat functional area prevent the front railing mounted on the scaffolding from tilting parallel to the fastening plane.

It is advantageously provided that the surfaces of the protective section, which are oriented towards the scaffold in the mounted state on the scaffold, are arranged in the fastening plane. In this embodiment, the entire safety bracket is designed in itself 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 securing bracket that is evenly designed 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 does not lie in the fastening plane.

Furthermore, it is advantageously provided in the proposal that the entire front side railing is designed to be rigid and, in particular, has no moving parts. It is particularly favorable that the front side railing is made rigid. As a result, the end railing is robust and reliable even in the 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 get dirty or corrode and are then no longer functional. In this case, a great safety risk can arise with such railings if the railings no longer function as intended. With a rigidly designed front side railing, such wear and tear on moving parts cannot occur at all, which is very advantageous for longevity and reliable function.

In a preferred embodiment of the proposal, it is provided that the vertical pins are essentially vertically oriented and rod-shaped in the mounted state on the frame. 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 end railing easy to manufacture. By arranging the vertical pins vertically, they can be inserted particularly easily into recesses on the frame. For some applications, however, it can also be advantageous to arrange the vertical pegs at a slight incline to the vertical, for example in order to bring about self-centering. The vertical pins can also be designed to be curved or bent. 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 pegs and the opposite, second end of the vertical pegs is intended to be inserted into the scaffold receptacles. In this embodiment, the upper, first end of the vertical peg ends flush with the fastening area, which in turn is attached to the fastening element with its side facing away from the vertical peg. The opposite, second end of the vertical pegs stands freely in the space and is intended to be inserted into a scaffolding receptacle 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 pegs and the areas of the fastening elements arranged adjacent to them 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 scaffold mounts. The fastening elements running in parallel can be used as handles, so that the front railing is easy to handle.

Cleverly it is provided that the vertical pins are arranged in a plane which is spaced apart and parallel to the fastening plane. In this embodiment the 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 front railing is arranged parallel to the rest of the scaffolding.

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

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

Furthermore, it is conveniently provided that at the end of the fastening elements pointing away from the protective section a horizontal pin is arranged 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 in the assembled state run essentially horizontally. These horizontal pegs are arranged on the fastening elements and point with their free end to the vertical pegs. There is a distance between the free end of the horizontal pegs and the vertical pegs that is greater than the distance that the recesses in the scaffold mount take up from the edge of the scaffold mount. This makes it possible to use the Insert vertical pins into the mounts without the horizontal pins standing up on the scaffold mount. If, however, an attempt is made to insert the vertical pins into other openings that are not intended for fastening the face railing to the scaffolding, then the horizontal pins form a stop which prevents the vertical pins from being inserted into these other openings. The horizontal pegs prevent the insertion of the vertical pegs into openings that are further spaced from the edge of an element than the distance between the free end of the horizontal pegs and the vertical pegs. The horizontal pegs thus 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 the fastening section are each part of the one-piece safety bracket. This embodiment can be produced particularly easily by bending a single tube. Of course, the protective section and the fastening section can also initially be produced separately and then connected to one another, for example by means of plug connections, screw connections or welded connections.

Furthermore, it is advantageously provided in the proposal that the protective section has an essentially U-shaped area and in this area at least one holding element is arranged that extends horizontally when it is mounted on the frame. An essential aspect of the end guardrail is to prevent workers from falling or falling off the scaffolding. For this purpose, the protective section must effectively block the face of the scaffolding. A favorable embodiment to achieve this is a U-shaped protective section in which, in addition to the complete closure of the space in the U, at least one holding element is arranged. Several holding elements can of course also be provided. The retaining element blocks the space between the legs of the U and at the same time serves as a handle for the assembly and disassembly of the front railing.

In a preferred embodiment of the proposal it is provided that the securing bracket is formed by a bent tube. This embodiment is as previously described very easy and inexpensive to manufacture. At the same time, a one-piece safety bracket has a high level of stability and is lightweight, since connecting elements between individual parts are saved.

The object of the invention is also achieved by a framework
at least one end face, this end face having a base frame with two horizontally spaced vertical standards and two vertically spaced horizontal bars, the horizontal bars connecting the vertical standards to one another, the horizontal bars and the vertical standards together defining an outer surface and at least two scaffolding mounts being arranged on the front side;
at least one end railing according to one of the preceding claims,
wherein one vertical pin is introduced into each scaffolding receptacle, and the fastening plane is congruent with the outer surface or is spaced apart 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 and described in the accompanying description. A framework according to the invention can have different sizes, depending on what is required 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 of the scaffolding. There are usually other base frames that are not arranged on the front side but are located within the framework. A base frame arranged on the front side forms the outer surface of the frame on the front side with its outwardly oriented surfaces. This outer surface forms the outermost end of the framework.

On the front side, in particular on the base frame, at least two scaffold mountings are provided, which are used to assemble the front side railing. These scaffold mounts can be firmly connected to the vertical posts or be formed by separate components that are connected to the vertical posts when the scaffold is being built. Furthermore, a scaffold according to the invention comprises at least one face railing according to one of the embodiments described above. The vertical pins of the front railing are in the scaffold mounts introduced and ensure a stable hold of the end railing on the other elements of the scaffolding. Due to the shape of the front railing, it is outside the other scaffolding elements, in particular outside the vertical posts. The fastening plane of the face 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, at a distance from the outer surface. And the rest of the scaffolding is to be understood here as all elements of the scaffolding that are not formed by the end railing. With this arrangement of the face railing congruently or outside the outer surface, the space between the two vertical posts of the base frame remains free to attach a standard railing there in addition and parallel to the face railing. A scaffold according to the invention thus enables the next higher floors to be erected quickly and safely. The advantage of a scaffolding according to the invention is that the front side railing has no moving parts and is therefore particularly robust. The front side railing can thus be stored and transported together with the other rigidly designed 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 scaffold according to the invention is therefore suitable for the harsh environmental conditions on a construction site and can therefore be transported and assembled with little expenditure of time.

It is also provided that the vertical pins are inserted into recesses in the scaffold mounts. In this embodiment, recesses are provided in the scaffolding receptacles into which the vertical pins are inserted. In this case, recesses are to be understood as meaning openings which correspond to the vertical pins. The vertical pins are conveniently simply pushed into the recesses. As a result, no tools are required for the assembly and disassembly of the end railing, so that 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 ledgers, whereby the front side railing is secured against tilting in this direction. In this embodiment, the next higher is used for the structure On the first floor, another vertical standard has already been installed on this next higher floor. When attaching the front railing, the guide is brought into operative connection with this further vertical post. As a result, in addition to being fastened by means of the vertical pins in the scaffolding mounts, the end side railing is connected to the additional vertical post via the guide. The front side railing is thus connected to the scaffolding at two points at a vertical height and is therefore even better secured. The guide prevents at least a tilting of the front side railing parallel to the front side. In a favorable manner, however, there is also a form fit between the guide and the additional vertical post, which also prevents tilting or separation of the front side railing from the frame in a direction perpendicular to the outer surface or front side.

It is cleverly provided that the guide has an opening on one side in a direction perpendicular to the horizontal ledgers, the width of which is greater than the outer diameter of the vertical bar. In this embodiment, the guide is designed so that it can be pushed over the vertical handle. This pushing onto the vertical post is expediently carried out after the front side railing is first rotated starting from its position which it assumes in the assembled state. This design means that no moving parts are required on the guide, which makes 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-face railing at least partially covers the distance between these vertical posts. In this embodiment, two further vertical posts are attached on the next higher 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 advantageously provided that a standard railing, which is arranged between two vertical posts, is attached parallel to the front side railing. In this embodiment of a scaffolding, a standard railing is already arranged parallel to and in addition to the front side railing on the front side, which additionally protects against falling.

Advantageously, it is 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 scaffold mounts and then the front side railing is pivoted about an axis that runs at right angles to the fastening plane, whereby the positive connection between leadership and vertical style is canceled. In this embodiment, only two movements of the end guardrail are required to dismantle the end guardrail from the rest of the scaffolding. First, the front railing is raised in the vertical direction until the vertical pins leave the recesses in the scaffold mounts. The front side railing can then be rotated or pivoted in a plane parallel to the fastening plane or the outer surface. The form-fitting connection between the guide and the vertical post is then canceled by pivoting along an axis which runs essentially at right angles to the fastening plane and / or outer surface of the end face. After this positive connection has been broken, the front side railing can simply be removed from the rest of the scaffolding in a direction at right angles to the front side. This means that the end guardrail can also be easily dismantled from the rest of the scaffolding without the use of tools.

• Connection of at least one further vertical post to the upper end of the base frame of the first floor arranged on the front side, the vertical post being arranged vertically above the first floor and belonging to the second floor of the scaffolding, the connection of the further vertical post only taking place if none of the The vertical standards of the first floor protrude to the second floor of the scaffolding,
• Attachment of a front side railing, according to one of the embodiments described above, the front side railing being attached exclusively from the first floor of the scaffolding by one person and first lifted outside the outer surface up to the level of the second floor, then the front side railing by a vertical to the outer surface arranged spatial axis is pivoted and in this pivoted state a guide is guided over the at least one further vertical post in the second floor, then the end side railing is pivoted back around the same spatial axis until the fastening elements are vertically aligned and this pivoting back creates a form fit between Guide and the further vertical post is produced and then the vertical pins are inserted into the scaffold mounts, the front side railing being moved vertically downward until the fastening areas on the scaffold mount en stand up, whereby the safety bracket of the end railing is attached outside of 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 falling of people. Scaffolding is usually erected on the ground or underground. Since the first floor of the scaffolding is located directly on the ground, no protection against falling people is required here. Such protection is only necessary from the second floor. A method according to the invention is therefore initially based on the construction of the first level 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 level of the scaffolding, at least two base frames, each consisting of two vertical posts and two horizontal bars, are connected to one another by means of horizontal struts. The horizontal struts are attached at right angles to the base frame at their corners. The result is a cuboid structure made of scaffolding elements. Next up is on the first floor of the A step covering is applied to the scaffolding, which serves as a stand area for the second floor. At this point, stepping on the step surface is dangerous because the second floor is not yet secured against falling. In some cases, a vertical post on the first floor extends up to the second floor. In this case, a railing on the front can be connected directly to this vertical standard. If there are not yet any vertical posts on the front side of the second floor, at least one further vertical post is first attached to the second floor, which then extends vertically upwards as an extension of the vertical post below. This additional vertical post 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 in time to attach two more vertical standards from the first floor to the second floor on the front side. An end railing according to the invention can be attached to both one and two vertical posts at the same time. Then, also from the first floor, an end railing is attached to the end of the second floor. For this purpose, the front railing is lifted up from below and first rotated or pivoted so that its guides can be pushed over the vertical standard or standards of the second floor. This rotation takes place around a spatial axis which is arranged perpendicular to the outer surface or front side of the site. In this twisted state, the face railing with its guides is pushed over the vertical standards. Once the vertical standards have been inserted into the guide (s), the front railing is rotated back around the spatial axis described. This creates a form fit between the front railing and the vertical standards. Details of this form fit, for which no moving parts are required, are described for the embodiments of the face railing and also apply to the method according to the invention. After turning back, the fasteners are again aligned vertically. In this state, the guides can be moved in the vertical direction along the vertical posts. The front side railing is now moved vertically downwards and its vertical pin is inserted into the scaffold mounts, in particular into recesses in the scaffold mounts. Finally, the front side railing with inserted vertical pins is moved vertically downwards until the fastening areas stand up on the scaffold mounts. In this state, the railing is firmly attached to the rest of the scaffolding. As a result of the vertical pegs introduced into the scaffold mounts, the front side railing can no longer be rotated about the spatial axis described above, whereby the form fit between the Guides and the vertical stems cannot be lifted. The method features described are expediently to be carried out precisely 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 comprises the further step

• Attachment of a second vertical post in 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 by a person standing on the tread and through the already attached front side railing 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 on the second floor, a second vertical post is attached to the front side, provided that no vertical post has yet been arranged at this point. The second, further vertical post is first pushed from above through the second guide, which is still free, and then connected to the base frame of the first floor. This work step is already carried out from the second floor of the scaffolding, since the front side of the scaffolding is already protected against falling by people by the 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.

It is expediently provided that the method comprises the further steps

• Attachment of a standard railing between the vertical posts on the front side of the second level of the scaffolding, the standard railing being provided for permanent protection of the front side against falls and the standard railing being arranged and fastened parallel to the front side railing,
• and dismantling of the front side railing, whereby this is first lifted vertically upwards by a person standing on the step surface of the second floor until the vertical pins are no longer in the scaffold recesses and then the front side railing is pivoted about a spatial axis perpendicular to the outer surface until there is no form fit there is more between the guides and the vertical posts of the second floor and the end side railing is finally moved away from the outer surface and is thereby separated from the rest of the scaffolding scaffolding. In further preferred process steps that are carried out according to those described above Process steps are carried out, a standard railing, which remains permanently on the scaffolding, is first mounted on the front side parallel to the front side railing. It is particularly advantageous that this standard railing can be installed parallel to the front railing. The person who mounts the standard railing is thus already protected against falling during its assembly by the attached front railing. After the standard railing has been attached, the front side of the corresponding floor is protected by it, so that the front side railing is no longer required. In the next steps, the front side railing is removed again by first moving it vertically upwards until the vertical pins are no longer in engagement with the scaffold mounts. Then there is again a pivoting about the spatial axis in order to cancel the form fit between the guides and the vertical posts. In this pivoted state, the front side railing can then be removed from the scaffolding along the spatial axis described. This front side railing is then advantageously 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 face railing, attaching the vertical posts, attaching the standard railing and dismantling the face railing for all in the vertical direction the following floors of the scaffolding are repeated above. The use and the method for securing the face of a scaffolding for the second floor of this scaffolding was described above. Of course, the method steps described can also be carried out for all the other floors of the scaffolding in order to secure the next higher floor against falling of people on the front side during assembly. It is particularly advantageous that only one front side railing is required per front side of the scaffolding, which is always attached to the next higher level in advance. After the parallel installation of a standard railing, this end railing can then be used again for the next floor. Only a small number of front side railings is therefore required for securing in accordance with the method described, 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 provided with the same reference symbols. In general, the described properties of an element which are described for one figure also apply to the other figures.

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

Between the vertically extending vertical posts 102, horizontally extending horizontal bars 103 are arranged. Two adjacent 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 standards 102. Such a base frame 106 is shown symbolically hatched at the bottom left. Base frames 106 are found at many other locations in the framework 100 and are a two-dimensional basic unit of this framework 100. The front side of the framework 100 is the narrow side of the framework pointing to the left and front. The hatched base frame 106 is part of the front and left-hand side of the scaffolding 100. The long side of the scaffolding 100 runs at right angles to the front side. Several horizontal struts 109 run horizontally in the direction of the long side.
Scaffold mountings 104 are arranged on at least some of the vertical posts 102, which are shown in detail in FIG FIGS. 6 to 8 you can see. These scaffolding receptacles 104 are interfaces for connecting various scaffolding elements to one another. The scaffold mountings 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 scaffold receptacles 104 as separate components, that is, not as components of the vertical posts 102. In the area of the framework 100 oriented to the front left, diagonally extending elements are furthermore arranged between two horizontal struts 109, which serve to additionally stabilize the framework 100. However, these diagonal elements are not always absolutely necessary. The base frames 106 arranged on the end face form an outer surface 105 with their outwardly oriented surface, that is to say with the surface that forms the temporal closure of the scaffold 100 in a plan view of the longitudinal side of the scaffold 100. This outer surface 105 is an imaginary auxiliary plane that the outer boundary of the frame 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 being outside the framework. So that the scaffold 100 can be safely walked on by people to work, the upper three floors each have step coverings 112. These step coverings 112 are each mounted in the horizontally running frame between two horizontal struts 109 and two horizontal bars 103, for example in this frame hung. Railings are provided so that workers on the higher levels cannot accidentally fall off the scaffolding. In the longitudinal direction, these are the longitudinal railings 111, and the standard railings 110 on the front sides 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, front side railings 1 are attached to both sides. When building the scaffolding 100 in the vertical direction upwards, the next floor is built up from the floor below. This state of the construction of the next floor is particularly critical, since in this state not all of the security elements are arranged on the next floor. The front side railing 1 is suitable for being mounted from the floor below to the next higher floor without the worker having to step onto the higher floor. If the worker then steps onto the next higher level during further construction, the front side is already secured against falling down by the front side railing 1. The front side railing 1 is therefore designed so that it can be installed very easily and quickly from the floor below. While the end railing 1 is attached to the top tier of the scaffolding 100, the other elements of the top tier are attached and fastened. Finally, a standard railing 110 is attached to the end faces for permanent protection against falling of the top floor. This standard railing 110 can be attached in parallel within the face railing 1, while the face railing 1 still remains on the scaffolding 100. This state is detailed in Fig. 8 to see. Finally, the front side railing 1 can be removed from the scaffolding again, the front side of the corresponding floor is then secured by the standard railing 110. The front side railing 1 can then be used to build the next floor above. Of course, a front side railing 1 can also be used for permanent protection of 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 Protective section 21 arranged at the top is essentially U-shaped and forms that part of the front side railing 1 which is intended to protect a worker from falling off the scaffolding 100. This U-shaped area blocks the front side of the framework 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 area 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 front side railing 1 during assembly or disassembly on the scaffolding 100. As shown, the protective section 21 can consist of two parts which are firmly connected to one another. Alternatively, the protective section 21 can also be composed of several parts, which, however, 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 is used to fasten the securing bracket 2 to the framework 100. In the embodiment shown, 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 area of the protective section 21. This means that the securing bracket 2 in the fastening section 22 is wider than in the protective section 21. The distance between the two fastening elements 221 is essentially the same the distance between two adjacent vertical posts 102 of the frame 100. The width of the protective section 21 is smaller than the distance between two adjacent vertical posts 102 of the frame 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. The entire securing bracket 2 is advantageously bent from a single tube. The fastening section 22 and the protective section 21 are thus made here from a single component and merge into one another. The fastening elements 221 can also have a shape other than the linear shape shown. The fastening elements can, for example, be curved or S-shaped. The mounting plane 222 is an imaginary auxiliary plane and in Fig. 2 shown as a rectangle. The mounting plane 222 is through the in Fig. 2 to the right back oriented surface of the two fastening elements 221 defined. The fastening plane 222 rests on the surface of the two fastening elements 221 that is oriented to the right rear and thus symbolizes the boundary of the fastening section 22 facing the framework 100. In the lower half of the two fastening elements 221, the vertical pins 3 oriented to the right rear are attached, each of which has a fastening area 31 are connected to the fastening elements 221. The vertical pegs 3 and the fastening areas 31 extend beyond the fastening plane 222 to the rear to the 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 run towards one another at an angle, so that they are oriented towards the respective opposite fastening element and have an angle of less than 90 ° to the fastening plane 222. 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 thus 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. It goes without saying that the vertical pin 3 and the 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 pegs 3 end flush with the lower ends of the fastening elements 221. The vertical pegs 3 and the fastening elements 221 run parallel to one another. At the lower end of the fastening elements 221, a horizontal pin 5 is attached, in Fig. 2 a horizontal pin 5 can only be seen on the left-hand side. The horizontal pegs 5 are attached at the same height as the downwardly pointing end of the vertical pegs 3 and point towards the vertical pegs 3. There is a distance between the ends of the horizontal pegs 5 and the lower ends of the vertical pegs 3 pointing away from the fastening elements 221. During the assembly of the front side railing 1 on the frame 100, the vertical pins 3 are inserted into frame mounts 104. The horizontal pegs 5 ensure that the vertical pegs 3 are actually inserted into the scaffolding receptacles 104 provided for this and are not improperly connected to other scaffolding elements. The Horizontal pegs 5 reduce the distance between the lower end of the fastening elements 221 and the lower end of the vertical pegs 3. If an attempt is made to insert the vertical pegs 3 into unintended scaffolding elements, the horizontal pegs 5 stand on these unintended scaffolding elements and introduce the vertical pegs 3 impossible. The horizontal pegs 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 approximately in the middle of the protective section 21, two guides 4 are arranged. 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 is shown in FIG Fig. 2 can be seen particularly well by the guide 4 oriented to the front right. Further details on the tours are in FIGS. 3 to 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 a hook-shaped functional surface. The guide 4 is provided to come into operative connection with vertically extending elements of the frame 100. With the end railing 1 mounted on the scaffold 100, a further connection to the scaffold 100 is established by the guide 4. The front side railing 1 is thus connected in a form-fitting manner to the scaffolding on the one hand by the vertical pins 3 introduced into the scaffolding receptacles 104 and on the other by the guide (s) 4. Should a worker fall against the front side railing 1, it is connected to the scaffolding by vertical pins 3 and guides 4, whereby the front side railing 1 is firmly and securely attached to the other scaffolding elements 100. The front side railing 1 is connected at its lower end to the scaffolding 100 with the vertical pins 3; a further connection is made further above via the guides 4, here approximately at the end of the top third of the front side railing 1. In the embodiment shown, the front side railing 1 is mounted thus connected to other elements of the framework 100 at four points and thus secured in a stable manner. The guides 4 also protrude to the rear to the right beyond the fastening plane 222 shown below. As a result, the securing bracket 2 is positioned outside the other scaffolding elements when the face railing 1 is mounted on the scaffold 100. The legs 41 of the two guides 4 on the right and left on the front side railing 1 are arranged in reverse. On the right-hand side, the leg 41 with the hook-shaped functional area is attached below the leg 41 with the flat functional area. On the opposite, left side, the arrangement is exactly the opposite. This mutually reversed arrangement of the legs 41 enables simple and yet secure assembly of the end railing 1. As in particular in FIG Fig. 5 As can be seen, the clear width between the rearwardly oriented ends of the legs 41 with the hook-shaped functional area is dimensioned smaller than the outer distance between two adjacent vertically extending elements of the frame. In the in Fig. 2 The orientation of the end railing shown in the figure, the rearwardly facing ends of the legs 41 with the hook-shaped functional areas undercut the vertically extending scaffolding elements, in particular vertical posts 102. Thus, the end railing 1 in the in Fig. 2 The orientation shown cannot be mounted on or removed from the framework 100 in a direction perpendicular to the mounting plane 222. For assembly or disassembly, the end guard rail 1 is pivoted about an axis perpendicular to the fastening plane 222. This increases the effective clear width between the legs 41 and the front side railing 1 can be mounted on the framework 100 or removed from it. The legs 41 are here made of flat metal, in particular iron or steel, and are welded to the protective section 21. Of course, the guides 4 can also consist of a different material and be connected to the securing bracket 2 by screw connections, for example.

Fig. 3 shows a front view of the front side railing 1 from Fig. 2 . Fig. 3 shows the end railing 1 from Fig. 2 viewed from the front left. Alternatively, in Fig. 3 The areas of two vertical posts 102 of the frame 100 which come into operative connection with the guides 4 are shown in dashed lines. At the lower end of the fastening section 22, the two vertical pins 3 can be seen, which in this view are oriented inward from the fastening elements 221. A guide 4, each with two legs 41, is arranged on the right and left of the protective section 21. On the right side, the lower, longer leg 41 is provided with a hook-shaped functional area. The leg 41 arranged above it 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 side railing 1 is connected to the two areas of the vertical posts 102 shown. As in Fig. 5 As can be seen, the two legs 41 with the hook-shaped functional areas undercut the two vertical posts 102 in the case shown. Thus, the front side railing 1 is 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 end-face railing 1 is 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 rotary movement, the legs 41 with the hook-shaped functional area are no longer in engagement with the vertical posts 102 and the front side railing 1 can after a rotary movement or twisting according to the arrow 111 in one direction out of the plane of the drawing can be removed from the vertical posts 102. This design of the guides 4 provides, on the one hand, a secure hold of the front side railing 1 on the scaffolding 100 in the assembled state and, on the other hand, the front side railing 1 can be mounted and dismantled on the scaffolding 100 by a simple pivoting. It is particularly favorable that the entire front side railing 1 is inherently rigid and has no moving parts. As a result, the front side railing 1 is robust and inexpensive to manufacture.

Fig. 4 shows a side view of the end railing from Fig. 2 . In Fig. 2 no elements of the framework 100 are shown. When viewed from the side, the fastening plane 222 appears like a line and is symbolized below the front railing 1 by a dashed line. It can be clearly seen that the surface of the fastening elements 221 oriented to the right defines the fastening plane 222. In the embodiment shown, the entire securing bracket 2 is flat, so that the surface of the protective section 21 oriented to the right 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 plane 222.

Fig. 5 shows a plan view of the front side railing 1 from Fig. 2 . In this view are also the vertical stems 102, which are already to Fig. 3 are shown in dashed lines for better understanding. These two vertical posts 102 are at an outer 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 can be clearly seen that the outer distance 502 is greater than the clear width 501 here. As a result, the legs 41 with the hook-shaped functional area of the front side railing 1 undercut the two vertical posts 102. As a result, 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 spacing 503. This leg spacing 503 is smaller than the inner distance between the two vertical posts 102. The vertical posts 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 produce a form fit with the vertical posts 102 of the framework 100. In order to be able to assemble or dismantle the end railing 1 in the direction of the arrow 504, a rotating or pivoting movement according to the in Fig. 3 indicated arrow 111 are carried out. After this rotary or pivoting movement has been carried out, there is no longer any form fit between the guides 4 and the vertical posts 102 and the end-face railing 1 can be moved in the direction of arrow 504.

Fig. 6 shows a perspective detailed view of a scaffold 100 with an end railing 1. In Fig. 6 only part of a scaffold 100 can be seen. A plurality of vertical posts 102 run vertically. A horizontal bar 103 runs in the horizontal direction on the front side. Two horizontal struts 109 run to the right rear, of which only the front one can be seen. A step covering 112 is inserted between the horizontal bar 103 and the horizontal struts 109, which here consists of two parts. The two vertical posts 102 arranged below the horizontal bar 103, the horizontal bar 103 shown, the two horizontal struts 109 and the two-part treading 112 belong to the first floor of the scaffolding 100, which is built on the floor or underground. The two vertical posts 102 attached above the horizontal bar 103 belong to the second level of the scaffolding 100. Scaffold mountings 104 are arranged on the vertical posts 102 and are designed here in the shape of a rosette. These scaffolding mountings are used to connect scaffolding elements that abut one another. The scaffold mountings 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 scaffold mountings 104. In the case shown, the scaffold mountings 104 are firmly connected to the vertical posts 102. However, it is also possible to design the scaffold mountings 104 as separate components that are plugged or screwed together with the vertical posts 102, for example. In the case shown, above the first floor shown, above the tread 112, two vertical posts 102 of the second floor run upwards. At the In the construction of the scaffolding 100, however, it can also happen that there is initially only one vertical post 102 above the top floor, which belongs to the second floor. A front side railing 1 is attached to the front of the second floor. This is inserted with its vertical pin 3 in recesses 1041 of the scaffold mounts 104. Further up, the two guides 4 form a form fit with the vertical posts 102, as previously for example Fig. 5 has been described. The front side railing 1 is thus connected to the other elements of the scaffolding 100 at two points in the vertical direction. Due to this double connection, on the one hand by the vertical pins 3 in the recesses 1041 and on the other hand by the guides 4, which enclose the upwardly extending vertical posts 102, the front side railing 1 is securely attached to the front side of the scaffolding 100 and thus effectively prevents falls. In order to be able to dismantle the front side railing 1 from the scaffolding 100 based on the case shown, the front side railing 1 is first lifted vertically upwards according to the arrow A until the vertical pins 3 leave the recesses 1041. The guides 4 can be displaced along the vertical posts 102 during this vertical movement. As soon as the vertical pegs 3 are no longer in the recesses 1041, the front side railing 1 can be rotated or pivoted according to the arrow B. The arrow B is shown in a plane parallel to the outer surface 105. A rotation or pivoting of the front side 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 exactly describe the pivoting or twisting. As a result of the rotation, the form fit between the guides 4 and the vertical posts 102 is canceled and the front side railing can be dismantled in the direction of the front side. The assembly of the end railing 1 is done in exactly the opposite way. First of all, one or both guides 4 (depending on which structural condition of the frame 100 is present) are pushed in a rotated position over the vertical post (s) 102. The front side railing 1 is then inserted into the in Fig. 6 The orientation shown is rotated back about the previously defined spatial axis and the vertical pins 3 are inserted into the recesses 1041 in a vertical downward movement. After the vertical pins 3 have been inserted into the recesses 1041, rotation according to arrow B is no longer possible. Thus, the form fit between guides 4 and vertical posts 102 cannot be canceled without a previous vertical movement. As a result, the front side railing 1 cannot be accidentally separated from the rest of the scaffolding 100. The described assembly of the end railing 1 is also easily possible from a floor below. The worker simply grips the fastening elements 221 and mounts the end railing 1 from below on the next higher floor. It is particularly advantageous that the front side 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 end face of the scaffolding 100. The standard railing 110 has the disadvantage that it can only be attached to the front side with great difficulty from the level below.

Fig. 8 shows a perspective detailed view of a scaffold 100 with a standard railing 110 and with an end railing 1. In Fig. 8 Both a standard railing 110 and a front side railing 1 are installed parallel to one another in the second floor of the scaffolding 100. A particular advantage of the front side railing 1 becomes clear here: the front side railing 1 has its securing bracket 2 arranged outside the outer surface 105 of the frame 100 defined by the vertical posts 102. In this way, 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 setting up the scaffolding 100, a front side railing 1 is first mounted as described from the floor below. The level 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.
