Description

The invention relates to a mounting adapter for the temporary attachment of a leading safety railing to a scaffolding during the erection and / or dismantling of the scaffolding.

The invention also relates to a safety railing for temporary attachment to a scaffolding during the erection and / or dismantling of the scaffolding, the safety railing securing the next scaffolding day until it is completed or a topmost scaffolding until it is completely dismantled.

The invention also relates to a kit for erecting scaffolding and a scaffolding.

Finally, the invention also relates to a method for erecting and dismantling scaffolding.

So-called leading safety railings for the fall protection of the topmost scaffolding levels of a scaffolding are known from the prior art. The safety railings are each assembled from the last completed, i.e. above all secured, scaffolding days to secure the next scaffolding days, i.e. from bottom to top during assembly. As soon as this next upper scaffolding level has been completed and secured, the safety railing can be used to temporarily secure the next higher scaffolding levels until they are completed. In a similar application, the safety railings can also be used when dismantling scaffolding.

The known safety railings are attached directly and centrally to the horizontal bars of the respective top floor, for example hung. It is exemplified in the publications EP 2 501 880 B1 , EP 2 730 718 B1 , EP 2 527 563 B1 and EP 2 180 117 B1 referenced.

It is also from the publications DE 10 2005 012 904 A1 and DE 103 05 158 A1 known that the safety railings are attached to the vertical bars of the scaffolding with struts or pins attached to the side.

The disadvantage of the known safety railings is that they are complicated to use and that the previously known safety railings are only compatible with scaffolding from a specific manufacturer.

Furthermore, the previously known temporary safety railings meet the safety standard TRBS 2121, which has been in place since February 2019 1 Not. This standard states, among other things, that two horizontal bars must be designed as fall protection on the temporary safety railing.

It is therefore the object of the invention to provide a leading safety railing and an alternative type of fastening of the safety railing to a scaffolding, which solve the problems mentioned above. A further object of the invention is to provide a corresponding scaffolding and method for this.

These objects are achieved by the features of the independent patent claims. Advantageous developments of the invention are the subject of subordinate claims.

The inventor has recognized that a flexibly usable safety railing can be provided by means of a mounting adapter which can be attached to the scaffolding on the one hand and to which the safety railing on the other hand. The mounting adapter can be designed so that the safety railing can be used with scaffolding from various manufacturers. Furthermore, the erection and dismantling of scaffolding with the help of such mounting adapters, to which the safety railing is temporarily attached, is possible without much additional effort.

In addition, two upper vertical bars can be formed in the safety railing that can be used with the mounting adapter, so that the above-mentioned safety standard is met.

Accordingly, the inventor proposes a mounting adapter for the temporary attachment of a leading safety railing to a scaffolding during the erection and / or dismantling of the scaffolding. In a preferred embodiment, the mounting adapter according to the invention is designed, on the one hand, for temporary attachment to a vertical spar of the scaffolding and, on the other hand, for temporarily fastening the safety railing to the mounting adapter.

For this purpose, at least one receiving unit for receiving fastening elements of a safety railing and at least one fastening device for attaching the mounting adapter to the scaffolding are particularly preferred.

The at least one receiving unit and, above all, the at least one fastening device can advantageously be designed in a very variable manner, so that the mounting adapter can be used on scaffolding from various manufacturers. In a simple but preferred embodiment, the receiving unit is a square tube educated. The square tube is advantageously made of a material that is as stable as possible, such as metal, preferably steel. The square tube is also preferably made in one piece in order to prevent possible material weaknesses or predetermined breaking points. In addition, the receiving unit designed as a square tube advantageously has a longitudinal extent along a longitudinal axis which is significantly larger than its diameter.

In a preferred embodiment of the mounting adapter, the at least one receiving unit has at least two grooves which, viewed in the mounted state of the mounting adapter, are arranged one above the other or one below the other. The grooves are advantageously of the same design, in particular of the same length and width.

Viewed in the assembled state, the two grooves are preferably arranged one above the other or one below the other. That is, the longitudinal extensions or the longitudinal axes of the grooves preferably run in one line. The grooves are advantageously designed to be elongated or slot-shaped. The fastening elements of the safety railing are advantageously received in the grooves of the at least one receiving unit. The slot-shaped grooves serve as a kind of guide for the fastening elements when hanging.

A further preferred embodiment therefore provides that the at least two grooves, viewed in the assembled state of the mounting adapter, each have an opening at their upper ends for inserting the fastening elements of the safety railing. When attaching the safety railing to the mounting adapters, the fastening elements are preferably simply inserted into the grooves from above. The lower, closed ends of the grooves accordingly form a stop for the fastening elements. In one variant, when the mounting adapter is in the mounted state, the openings of the grooves are arranged on the building side, that is to say at the rear. In another variant, when the mounting adapter is in the assembled state, the openings are arranged on the outside, that is to say oriented in front of or away from the building. Another variant provides for the grooves to be arranged on the side of the receiving unit.

It should be noted that any relative location terms used always relate to the mounted state of the mounting adapter or, furthermore, to the attached state of the safety railing on the scaffolding.

In one embodiment of the mounting adapter, precisely one receiving unit is designed for receiving fastening elements of a safety railing.

In another embodiment of the mounting adapter, two receiving units are designed for receiving fastening elements from two safety railings.

To save weight, for example, recesses can be formed in the receiving units.

Each receiving unit can have two or more grooves. At least two grooves are arranged on one side of a receiving unit. According to a preferred embodiment, each receiving unit has at least one mounting plane in which the grooves extend, the at least one mounting plane being laterally offset and arranged parallel to a fastening axis of the mounting adapter. In a preferred embodiment, the fastening axis of the mounting adapter corresponds to the vertical spar of the scaffolding to which the mounting adapter is fastened in the assembled state. Accordingly, the fastening axis advantageously runs outside the receiving unit (s).

A variant provides that a receiving unit has exactly one mounting plane. Another variant provides that a receiving unit has two or three mounting levels. The assembly plane (s) advantageously runs parallel to an outside of the receiving unit. According to a particularly advantageous embodiment, the mounting plane corresponds to an outside of the receiving unit.

In one embodiment, two adjacent receiving units each have a mounting plane, the mounting planes being aligned parallel to one another. In principle, adjacent receiving units correspond to either the two receiving units of a mounting adapter or the two receiving units of two mounting adapters, between or to which a safety railing is attached.

In a further embodiment, two adjacent receiving units each have a mounting plane, these two mounting planes being at an angle to one another. A mounting adapter with two mounting levels at an angle to one another is advantageously suitable for attaching a safety railing to scaffolding at a corner of a building. The corner of the building can either be an inside corner or an outside corner of the building. In this embodiment, the assembly planes are preferably at an angle of 90 ° to one another. However, a design with an angle not equal to 90 ° is also within the scope of the invention in order to attach safety railings to scaffolding for buildings with non-right-angled inner and / or outer corners.

A particular embodiment provides that a receiving unit has two mounting planes which are at an angle, preferably at a 90 ° angle, to one another.

According to the invention, each receiving unit has at least two grooves, the grooves being arranged in an assembly plane.

According to one embodiment, the at least one receiving unit has two grooves in an assembly plane.

According to a further embodiment, the at least one receiving unit has at least one additional groove in a mounting plane. For example, three or four etc. grooves, but preferably three grooves, are thus formed in one assembly plane. Correspondingly, an embodiment is also possible in which a receiving unit has two mounting levels with different numbers of grooves, for example two grooves in one mounting level and three grooves in the other mounting level.

Another regulation for safety railing states that the fastening of the safety railing must have a minimum stroke with which the safety railing must be able to move upwards without the fastening of the safety railing becoming detached. Accordingly, one embodiment provides that the grooves are designed in such a way that a lifting height of the safety rail of at least 15 cm is necessary to unhook the fastening elements of the safety railing from the grooves. In other words, the grooves - in the assembled state, that is to say with the opening facing upwards - preferably have a depth or length of at least 15 cm. This value of the minimum depth of the grooves corresponds to the sum of the maximum stroke height of a fastening element in the groove and the diameter of the fastening element.

Both the attachment of the mounting adapters to the scaffolding and the fastening of the safety railing to the mounting adapters are carried out manually. In order to facilitate the hanging of the safety railing in the mounting adapter, that is to say the insertion of the fastening elements into the grooves, an insertion rail is advantageously formed in each case on a lower region of the opening of the grooves. In a simple embodiment, the insertion rail is designed as a kind of lip. The lip can, for example, simply be welded to the opening of the groove on a metal receiving unit.

The mounting adapter according to the invention has at least one fastening device for attaching the mounting adapter to the scaffolding, preferably to a vertical spar of the scaffolding. In order to ensure secure fastening, the mounting adapter has more than one fastening device, advantageously two fastening devices.

One embodiment provides that a first fastening device is designed as a manually releasable screw-clamp connection. Such a connection can advantageously be operated without tools and with one hand.

Another embodiment provides a further fastening device which is designed as a securing unit which forms a stop on the scaffolding to prevent it from falling. The securing unit is advantageously designed as a type of hook. This hook can, for example, be hung in a gusset plate under a scaffolding floor or in a horizontal beam of the scaffolding. The securing unit also advantageously enables the mounting adapter to be attached to the vertical spar at a defined height. Likewise, the mounting adapter can initially simply be hung on the scaffolding by means of the securing unit in order to prevent it from falling, and then be fixed to the vertical spar by means of the first fastening device.

Yet another embodiment provides at least one further fastening device which forms a stop on the scaffolding to prevent it from slipping sideways. The stop is preferably formed at least on a vertical spar to which the mounting adapter is attached. As a result, lateral slipping can advantageously be prevented during the assembly of the assembly adapter. In a variant, a V-shaped, upwardly open groove is formed in the upper region of the mounting adapter, in which part of the scaffolding, in particular a horizontal beam or a gusset plate, can advantageously be positioned during assembly.

The groove can be formed, for example, on a type of handle or arcuate stop which engages around the vertical spar to which the mounting adapter is attached. In another, additional or alternative variant, a type of double cheek with a central recess is formed in a lower area of the mounting adapter, the vertical spar to which the mounting adapter is attached advantageously being in the recess is positioned. Preferably, both variants in combination, i.e. the handle with the groove and the double cheek, enable optimal positioning and securing of the mounting adapter.

Furthermore, the invention relates to a safety railing for temporary attachment to a scaffolding when erecting and / or dismantling the scaffolding, the safety railing securing the next scaffolding level during construction or a top scaffolding level until it is completely dismantled, the safety railing is designed such that it can be temporarily attached to the scaffolding by means of at least one assembly adapter according to the invention, described above.

In a preferred embodiment, the safety railing according to the invention has at least one horizontal spar and two laterally arranged vertical spars, between which the at least one horizontal spar extends, with laterally arranged fastening elements being formed on the vertical spars, which are temporarily in the receiving units when the scaffolding is being erected and dismantled the mounting adapter can be used. The safety railing is advantageously attached to a mounting adapter on both sides. For this purpose, the fastening elements of the safety railing are inserted into the receiving units, more precisely into the grooves of the receiving units.

A preferred embodiment therefore provides that the fastening elements are designed to be essentially complementary to the receiving units, in particular to the grooves on the receiving units.

A further embodiment provides that the fastening elements are designed in the shape of a pin with a thickened portion at the end, the pin being designed to be inserted into the groove. The diameter of the pin is advantageously smaller than the width of the groove in order to allow the pins to slide in the groove as smoothly as possible. Preferably, however, the diameter of the pin is only a few millimeters smaller than the width of the groove in order to avoid unnecessary play, which would lead to instability of the safety railing, but to allow unhindered sliding in the groove. At the end, that is to say at the ends, the pin advantageously has a thickening in order to prevent unintentional pulling out or lateral loosening of the pin from the groove. If the pin is inserted into the groove, the thickening is advantageously located inside the receiving unit. For example, the pin-shaped fastening elements with a thickened end portion are designed as mushroom head screws.

The number of fastening elements per vertical spar preferably corresponds to the number of grooves per receiving unit. Thus, each fastening element for fastening the safety railing to the mounting adapters can be inserted into a groove in order to ensure a secure fastening, in particular a secure fastening.

As already stated above, a safety regulation for safety railings states that the fastening must withstand a stroke of at least 15 cm before the safety railing is released from the fastening.

• D: Breite der Nut,
• d: Durchmesser des Zapfens in der Nut,
• h: Abstand vom oberen zum unteren Zapfen,
• H: Abstand vom oberen Zapfen zum oberen Vertikalholm, und
• A: Auslenkung des Geländers am höchsten Punkt bei einer Belastung mit einem Gewicht von 30 kg.

Another safety regulation states that the uppermost point of the safety railing may only move a maximum of 3.5 cm outwards, i.e. away from the building, with a lateral load of 30 kg. In order to comply with this safety regulation, a preferred embodiment therefore provides that the value A = (Dd) * H / h is a maximum of 3.5 cm, where:

• D: width of the groove,
• d: diameter of the pin in the groove,
• h: distance from the upper to the lower pin,
• H: Distance from the upper journal to the upper vertical spar, and
• A: Deflection of the railing at the highest point with a load of 30 kg.

In a preferred embodiment, the fastening elements are arranged in the lower region of the vertical bars of the safety railing. The safety railing is therefore fastened to the mounting adapters in the lower area and then advantageously extends essentially upwards in the direction of the uppermost scaffolding level to be secured.

Another safety regulation states that a safety railing must have at least two horizontal bars in the upper area, i.e. as a temporary railing as fall protection for a scaffold builder. Accordingly, a preferred embodiment provides that two upper horizontal bars and one lower horizontal bar are formed. The two upper horizontal bars serve as fall protection and form the actual railing, and the lower horizontal bar essentially serves to stabilize the safety railing. For further stabilization of the safety railing and for further protection against falling, cross braces can advantageously be formed at least between the two upper horizontal bars.

In order to enable easy handling of the safety railing, in an advantageous embodiment at least one handle for inserting the safety railing into the mounting adapter is formed on the lower horizontal bar. The handle is designed, for example, as a U-shaped spar that is easy to grip.

Another embodiment of the safety railing provides that the at least one horizontal spar is designed to be telescopic. The width of the safety railing can thus advantageously be set variably. Adjusting elements can optionally be formed on the telescopic horizontal bars, which fix the bars to a specific length or width. Furthermore, the at least one telescopic horizontal spar is advantageously connected to the vertical spars via joints. This enables greater variability of the safety railing in use.

In addition, the invention relates to a kit for erecting scaffolding, at least comprising: several scaffolding floors and several vertical and horizontal spars including their connecting elements for the erection of several superimposed scaffolding levels, at least one inventive safety railing described above, and at least two inventive mounting adapters described above for temporary fastening of the safety railing to the scaffolding during assembly and / or dismantling. The horizontal bars of the kit advantageously form the actual scaffolding railing, which remains permanently on the respective scaffolding level.

The invention also relates to a scaffolding, erected from a kit according to the invention described above.

At least one set-up day segment is provided for each set-up day. In other words, a complete scaffolding stage is formed from at least one, advantageously several, scaffolding stage segments. The uppermost scaffolding tier or a respective uppermost scaffolding tier segment is temporarily secured by the safety railing according to the invention until completion, in particular until it is secured with the actual scaffolding railing.

The construction and dismantling of the scaffolding according to the invention with the safety railing according to the invention is possible either in floors or in segments. The individual process steps of the method according to the invention for assembly and dismantling are each described for a scaffolding segment and can be repeated in any order and number in order to build and secure the scaffolding completely and with all scaffolding segments.

• - Anschlagen jeweils eines Montageadapters an zwei benachbarten bereits errichteten Vertikalholmen,
• - Einsetzen eines Sicherheitsgeländers in die beiden Montageadapter zum Schutz des nächsten oberen Gerüstetagensegments von dem letzten gesicherten Gerüstetagensegments aus,
• - Fertigstellen des oberen Gerüstetagensegments einschließlich Einrichten eines Gerüstgeländers zwischen den Vertikalholmen, und
• - Wiederholen der voranstehenden Verfahrensschritte nach Bedarf.

Finally, the invention also relates to a method for assembling a scaffolding according to the invention described above from a kit according to the invention described above, at least comprising the following method steps:

• - Attachment of a scaffolding floor of the next upper scaffolding segment on already erected vertical spars of a last secured scaffolding segment,
• - Attach a mounting adapter to two adjacent vertical bars that have already been built,
• - Insertion of a safety handrail in the two mounting adapters to protect the next upper scaffolding segment from the last secured scaffolding segment,
• - Completion of the upper scaffolding segment including setting up a scaffolding railing between the vertical spars, and
• - Repeat the above procedural steps as required.

According to the invention, the safety railing is attached to the scaffolding from below in such a way that it secures the uppermost, that is to say the next scaffolding level to be completed. As soon as the safety railing is attached, the top scaffolding level can be completed, above all the actual scaffolding railing can be attached. A scaffold builder is therefore never unsecured.

• - Anschlagen jeweils eines Montageadapters an zwei benachbarten Vertikalholmen unterhalb des letzten gesicherten Gerüstetagensegments,
• - Einsetzen des Sicherheitsgeländers von dem letzten gesicherten Gerüstetagensegment aus,
• - Entfernen des Gerüstgeländers und des Gerüstbodens sowie falls vorhanden der Vertikalholme des obersten Gerüstetagensegments, und
• - Wiederholen der voranstehenden Verfahrensschritte nach Bedarf.

The invention also relates to a method for dismantling an above-described scaffolding according to the invention from an above-described kit according to the invention, at least having the following method steps:

• - Attach a mounting adapter to two adjacent vertical bars below the last secured scaffolding segment,
• - Insertion of the safety railing from the last secured scaffolding day segment,
• - Removal of the scaffolding guardrail and the scaffolding floor and, if present, the vertical spars of the top scaffolding stage segment, and
• - Repeat the above procedural steps as required.

When dismantling, according to the invention, the top scaffolding floor is first secured by the Safety railing dismantled down to the scaffolding floor. The safety railing can then be set one day further down from below, i.e. from the last complete and secured scaffolding days. The scaffolding worker is therefore always secured, even during dismantling.
