Description

The invention relates to a scaffolding frame with two parallel extending vertical posts of different lengths which are inextricably connected to one another by a non-releasable crossbar. The invention further relates to scaffolding systems with at least one scaffolding frame. The invention also relates to scaffolding segments with at least two scaffolding frames. Finally, the invention relates to scaffolding with at least four scaffolding frames.

Scaffolds are used, for example, as shoring for supporting loads and as working scaffolding, in particular as facade scaffolding, with working levels for workers. So-called frame scaffolds allow simplified handling and particularly rapid assembly and dismantling of the scaffolding. Such frame scaffolding includes scaffolding frames with two vertical posts which extend parallel to one another and which are inextricably connected to one another by a non-releasable crossbar. The vertical stems can be of different lengths.

Such a scaffolding frame is, for example, from the brochure “PERI UP Easy - The light and fast facade scaffolding for safe work”, accessed on December 19, 2018 at the URL https://www.peri.de/resources/brochures/jcr:a0edfda0-f692 -4f81-a77a-lae6f9deacec / PERI-UP-Easy.pdf, known. The lengths of the vertical posts and their relative arrangement to one another are selected and coordinated in the known scaffolding frame so that an intermediate post, which compensates for the length difference between the longer and the shorter of the vertical posts, is provided between the shorter vertical posts of two scaffolding frames arranged one above the other got to.

It is an object of the invention to provide a scaffolding frame for a simple and flexible construction of scaffolding with a plurality of such scaffolding frames.

This object is achieved according to the invention by a scaffolding frame having the features specified in claim 1. Scaffolding systems according to the invention have those in the claims 7th and 8th specified features. The features of framework segments according to the invention are set out in the claims 9 and 10 described. Scaffolds according to the invention are in the claims 13 and 14th specified. Advantageous embodiments are specified in the respective subclaims and in the description.

Scaffolding frames according to the invention

The scaffolding frame according to the invention has a first and a second vertical post. The vertical stems extend parallel to one another. The vertical posts each have a lower and an upper support surface. When building a scaffold with the scaffolding frame, further post elements, for example the vertical posts of further scaffolding frames according to the invention, rest on the support surfaces. The first vertical post has a first length, measured from its lower to its upper support surface. The second vertical post has a second length, measured from its lower to its upper support surface. The first length of the first vertical post is greater than the second length of the second vertical post. Provided that one or both of the vertical posts protruding beyond the bearing surfaces in the direction of extension of the vertical posts, for example push pins or insert pins for inserting the vertical post into another vertical post, these do not count towards the first or second length of the vertical posts. The two vertical standards are permanently (permanently) connected to one another by a non-releasable crossbar. Permanently connected means permanently, in particular not detachable in a non-destructive manner. The non-detachable crossbar is typically welded to the two vertical posts. Due to the connection by the non-detachable crossbar, the two vertical standards can be handled together. Due to the connection by means of the non-detachable cross bar, the parallel alignment of the vertical standards is also established. The non-detachable crossbar is typically attached to the second vertical post near the upper support surface, preferably in the upper third, particularly preferably in the upper quarter, of the length of the second vertical post.

According to the invention, a first distance measured parallel to the vertical posts between the lower support surface of the first vertical post and the lower support surface of the second vertical post is the same as a second distance measured parallel to the vertical posts between the upper support surface of the first vertical post and the upper support surface of the second vertical post . In other words, the lower support surfaces of the two vertical posts - viewed in the direction of extension of the vertical posts - are spaced from one another by the first distance. The upper bearing surfaces are correspondingly spaced from one another by the second distance. The first distance corresponds to the second distance. This makes it possible to arrange two similar scaffolding frames according to the invention directly one above the other. The upper scaffolding frame can rest with the lower bearing surface of its first vertical post directly on the upper bearing surface of the second vertical post of the lower scaffolding frame. At the same time, the Rest the lower support surface of the second vertical post of the upper scaffolding frame on the upper support surface of the first vertical post of the lower scaffolding frame.

Directional indications such as above, below or vertical relate in the context of the present invention to the regularly constructed state of a scaffold or scaffold segment with a scaffold frame according to the invention. In special cases, a different arrangement of the scaffolding frame according to the invention or the scaffolding or scaffolding segment constructed therewith can also be provided.

In the case of the scaffolding frame, the first length of the first vertical post is preferably three times as large as the second length of the second vertical post. Scaffolding segments or scaffolding can advantageously be constructed from such scaffolding frames. In particular, the first length can be 1.5 m and the second length can be 0.5 m. By arranging such a first and a second vertical post directly one above the other, a distance - measured parallel to the vertical posts - can be set up between the non-detachable crossbars of adjacent scaffolding frames of 1.0 m. In this way, very stable (supporting) scaffolding can be built. Apart from a possibly required lower base frame and an upper head frame, only scaffolding frames of the same type are required for this. The distance between the non-detachable crossbars can, if necessary, be increased by inserting intermediate posts. Especially with scaffolding frames with the above-mentioned first and second lengths of 1.5 m and 0.5 m with intermediate posts of 1.0 m each, the distance between the non-detachable crossbars can be increased to 2.0 m. In this way, work / facade scaffolding can be set up with the level spacing of 2.0 m that is usual in the construction sector. For this purpose, only scaffolding frames of the same type and intermediate posts as well as, if necessary, base frames are required.

Further combinations with intermediate posts with lengths of 0.5 m, 0.75 m, 1.0 m, 1.25 m, 1.5 m or 1.75 m can be used, which means that the distances between the non-detachable crossbars are 1 , 50 m or 1.75 m can be reduced or 2.25 m or 2.5 m, 2.75 m or 3.0 m increased. Thus, the distance between the working levels of a work / facade scaffolding can be adapted to different sizes of workers (e.g. small for workers from the Asian region or large for workers from the Scandinavian region).

The first and the second distance can each be the same size as the second length of the second vertical post. Such scaffolding frames can be combined in a variety of ways to form a scaffold or scaffold segment, in particular without the need for compensating elements such as e.g. the aforementioned intermediate stems, must be provided.

The first vertical post particularly preferably has several, in particular three, connection elements for connecting further frame elements. The further scaffolding elements can serve to stiffen a scaffolding built up with the scaffolding frame. The additional scaffolding elements can be used to stiffen scaffolding with the scaffolding frame depending on the required load-bearing capacity or predetermined load class of the respective scaffolding.

The second vertical post typically also has a connection element for connecting further frame elements. The connection element on the second vertical post is preferably arranged at the same height - with respect to the direction of extension of the vertical posts - as one of the connection elements of the first vertical post. In particular, a connection element can be provided directly below the non-releasable cross bar on the first and second vertical post.

The connection elements can each be designed in the form of a perforated disk or a framework rosette. In particular, at least some of the scaffolding rosettes can be designed as a full rosette that fully encompasses the scaffolding post. Full rosettes allow the greatest possible flexibility when connecting the other scaffolding elements. Alternatively, at least some of the scaffolding rosettes can be designed as a partial rosette, in particular as a three-quarter rosette. Such rosettes are preferably provided on the vertical posts near the non-releasable crossbar, in particular immediately below the non-releasable crossbar.

According to the invention, a third distance between two of the connecting elements of the first vertical post is preferably the same as the second length of the second vertical post. In particular, adjacent connection elements of the first vertical post can each have the third distance. As the third distance and the second length match, further scaffolding elements can be arranged uniformly on a scaffolding with the scaffolding frame.

According to the invention, the two vertical stems can each have a push-in or plug-in pin that protrudes beyond the upper support surface of the respective vertical stem, ie extends beyond the upper support surface of the respective vertical stem in its longitudinal direction, and that the two vertical stems each have a receiving section on the lower support surfaces Have insertion of a plug-in pin. The push or insertion pin can each be in the receiving sections of the Vertical posts, in particular similar scaffolding frames, are inserted. In this way, a load-stable connection of the scaffolding frame can be obtained quickly and easily. The upper and lower bearing surfaces then come directly into contact with one another. The insertion pins and receiving sections of the two vertical stems are typically designed in the same way. This offers manufacturing advantages. In particular, they can be dimensioned such that each of the insertion pins can be inserted into each of the receiving sections. One of the insertion pins can be made longer than the respective other insertion pin for particularly simple assembly.

Scaffolding systems according to the invention

The scope of the invention also includes a scaffolding system comprising at least one scaffolding frame according to the invention described above and a base frame with two base posts extending parallel to one another and each having an upper contact surface. According to the invention, a fourth distance measured parallel to the base posts between the upper contact surfaces of the base posts is the same size as the first distance between the lower contact surfaces of the two vertical posts of the scaffolding frame. The scaffolding frame of this scaffolding system can therefore be arranged directly on the base frame. The lower bearing surfaces of the vertical standards can be in direct contact with the upper bearing surfaces of the basic standards.

The base frame can be placed on the ground. For this purpose, the base posts preferably each have a set-up surface arranged at the same height — with respect to a direction of extension of the base posts. If necessary, the installation surfaces can also be supported on leveling devices such as spindles. This means that unevenness in the subsurface can be compensated for in a simplified manner. The basic standards are always permanently connected to one another by a basic crossbar. In particular, the base posts can each be welded to the base cross bar. The two base posts of the base frame and the two vertical posts of the scaffolding frame are basically equidistant from one another perpendicular to their respective direction of extension.

Also within the scope of the invention is a scaffolding system comprising at least one inventive scaffolding frame described above and a head frame with two head posts extending parallel to one another, each having a lower support surface. According to the invention, a fifth distance measured parallel to the head posts between the lower support surfaces of the head posts is the same as the second distance between the upper support surfaces of the two vertical posts of the scaffolding frame. The head stems are always permanently connected to one another by a head cross bar. In particular, the head posts can each be welded to the head cross bar. The head frame can therefore be arranged directly on the scaffolding frame. The lower support surfaces of the head stems can be in direct contact with the upper bearing surfaces of the vertical stems. A scaffold segment or scaffold built up from this scaffolding system can be closed on the top side by means of the head frame. In particular, loads can be introduced into the scaffolding segment or scaffolding via the head frame. The two head posts of the head frame and the two vertical posts of the scaffolding frame are basically equally spaced from one another perpendicular to their respective direction of extension. This scaffolding system typically also comprises a base frame of the scaffolding system described above.

Scaffolding assemblies according to the invention

The scope of the invention also includes a first scaffold segment with at least two scaffold frames according to the invention described above, the first vertical posts of the scaffold frames being arranged in extension from one another and the second vertical posts being arranged in extension from one another. In other words, the first vertical posts of the scaffolding frames of the scaffolding segment are each arranged one above the other. The second vertical posts of the scaffolding frames of the scaffolding segment are correspondingly arranged one above the other. Such a scaffolding segment is particularly suitable for the construction of a facade scaffolding, with scaffolding coverings being able to be attached to the non-detachable crossbars of the scaffolding frames. A first intermediate post can in each case be arranged between two successive first vertical posts. As a result, a distance between the non-detachable crossbars that is suitable for a facade scaffolding can be established. In principle, a second intermediate post is arranged between the second scaffold posts. The second intermediate post is longer than a possibly provided first intermediate post. Typically, all of the first or all of the second intermediate posts of the framework segment are each of the same length.

Also within the scope of the present invention is a second scaffolding segment with at least two scaffolding frames according to the invention described above, a first and a second vertical post of one of the scaffolding frames in each case - in the direction of extension of the vertical posts - being arranged one after the other. In other words, the first and second vertical posts of the scaffolding frames follow one another in alternation. A first vertical post of one of the scaffolding frames is in each case Extension of a second vertical post of one of the adjacent scaffolding frame or frames. Such a frame segment is characterized by great rigidity and stability or resilience.

In the case of the second scaffolding segment, the lower bearing surfaces of the vertical posts of one of the scaffolding frames can each rest directly on the upper bearing surfaces of the vertical posts of another of the scaffolding frames. A particularly great rigidity and stability or load-bearing capacity of the framework segment can thereby be achieved. Such a frame segment is particularly suitable for the construction of a support frame for supporting loads.

Alternatively, in the case of the second frame segment, a third intermediate post can be arranged between the vertical posts. This allows the distance between two consecutive non-releasable crossbars to be increased; this particularly enables height compensation. Such a scaffolding segment is particularly suitable for the construction of a facade scaffolding with working levels spaced apart in a defined manner at the level of the non-detachable crossbars. For this purpose, scaffolding decks can be attached to the non-detachable crossbars. The third intermediate posts are each the same length for a pair of consecutive scaffolding frames. Typically, all third intermediate posts of the framework segment or of the framework are of the same length.

Scaffolding according to the invention

The scope of the invention also includes a first scaffold with at least two scaffold segments according to the invention described above, it being provided that the scaffold segments are connected to one another by at least two detachable horizontal bars. If the framework has more than two framework segments, neighboring framework segments are typically connected to one another by at least two detachable horizontal bars. Usually the frame segments are aligned parallel to one another. The detachable horizontal bars can be attached to connection elements provided for this purpose on the vertical standards and, if necessary, on the intermediate standards. The scaffold segments are held at a defined distance from one another by the detachable horizontal bars. In addition to the detachable horizontal ledgers, diagonal elements can be provided to further stiffen the scaffolding.

According to the invention, the detachable horizontal bars for a construction as a facade / work scaffolding can be arranged at the level of the non-detachable cross bars of the scaffolding frame. Scaffolding decks can be arranged between the non-releasable cross bars and / or releasable horizontal bars.

Alternatively, additional crossbars in the form of detachable horizontal bars can be provided in other positions for a structure as a support structure. As a result, the load-bearing capacity of the scaffolding can be further increased at the required positions.

Finally, a second scaffold with at least four scaffolding frames according to the invention described above falls within the scope of the earth invention, each of which is arranged in pairs at the same height - with respect to a direction of extension of the vertical posts - in parallel side planes of the scaffolding, with their respective first and second vertical posts are arranged oppositely. By arranging the respective scaffolding frames of the pairs at the same height, in particular the non-detachable crossbars of the respective scaffolding frames are arranged at the same height. Opposite means in particular that the two scaffolding frames of one of the pairs cannot be converted into one another (mapped onto one another) by a pure translation, but that in addition to the translation for the transfer into the respective other side plane, a rotation of 180 ° around a vertical axis is required To convert scaffolding frames into one another. When looking at one of the side planes, a first and a second vertical post are each one of the scaffolding frames in front of or behind one another. Immediately successive pairs of scaffolding frames are each arranged in side planes of the scaffolding that are perpendicular to one another. The framework is therefore cuboid with a square cross section (in a horizontal plane). The four scaffolding frames define the four side levels of the cuboid scaffolding. This structure makes it possible to obtain great rigidity and stability or resilience of the frame, in particular for use as a supporting frame.

In the second frame, the lower bearing surfaces of the first vertical posts of one of the pairs of scaffolding frames each lie directly on the upper bearing surfaces of the second vertical posts of another of the pairs of scaffolding frames and the lower bearing surfaces of the second vertical posts of one pair of scaffolding frames each lie directly on the upper bearing surfaces of the first vertical standards of the other pair of scaffolding frames. As a result, the rigidity and stability or load-bearing capacity of the framework can be increased further. In addition, such a scaffolding can be set up particularly quickly. For this purpose, only the same type of scaffolding frames according to the invention and typically base frames and, if applicable, head frames of scaffolding systems according to the invention are required.

As an alternative to this, a third intermediate post can be arranged between the vertical posts in the second frame. This allows to The purpose of height adjustment is to increase the distance between two successive crossbars.

Preferably, a scaffold according to the invention further comprises two head frames of a scaffold system according to the invention, the lower support surface of at least one of the head posts of the head frames in each case resting directly on the upper support surface of one of the vertical posts of the scaffold frames. This makes it possible to obtain great rigidity and stability or resilience of the framework. The head frames can each be placed with their two head posts directly onto one of the vertical posts of the scaffolding frame. As a result, the rigidity and stability or load-bearing capacity of the framework can be increased even further. To adjust the height of the framework, an intermediate post can alternatively be arranged between each head post of the head frame and one of the vertical posts. In particular, the lower support surfaces of the longer head posts can each rest directly on the upper support surfaces of the first vertical posts and a fourth intermediate post can be arranged between the shorter head posts and the second vertical posts for the purpose of height compensation. The fourth intermediate posts are typically arranged diametrically in the plan of the framework. Both head posts of one of the head frames can be arranged as an extension of the two vertical posts of a scaffolding frame. Alternatively, one of the head posts of the head frame can be arranged as an extension of one of the vertical posts of each of two adjacent scaffolding frames.

Further advantages of the invention emerge from the description and the drawing. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for describing the invention.

The 1a , 1b show a scaffolding frame 10 in a perspective or side view. The scaffolding frame 10 has a first vertical stem 12 and a second vertical post 14th on. The two vertical stems 12 , 14th extend parallel to each other. The vertical stems 12 , 14th are by an inseparable crossbar 16 of the scaffolding frame 10 inextricably (permanently) connected to one another and can in particular be welded to one another.

The first vertical stick 12 has a lower support surface 18th and an upper support surface 20th on. The distance between the lower support surface 18th from the upper support surface 20th defines a first length 22nd of the first vertical post 12 . The second vertical stem 14th has a lower support surface 24 and an upper support surface 26th on. The distance between the lower support surface 24 from the upper support surface 26th defines a second length 28 of the second vertical post 14th . The first length 22nd of the first vertical post 12 is greater than the second length 28 of the second vertical post 14th . The first length 22nd can in particular be three times as large as the second length 28 . In particular, the first length 22nd in the illustrated embodiment 1.5 m and the second length 28 0.5 m.

In the direction of extension of the vertical stems 12 , 14th , ie parallel to them, is the lower support surface 18th of the first vertical post 12 from the lower support surface 24 of the second vertical post 14th by a first distance 30th spaced.

On the first vertical post 12 are three connection elements here 38 designed for attaching further scaffolding elements. The connection elements 38 are advantageous as perforated disks or scaffolding rosettes 40 executed. One of the connection elements 38 , here the middle one, is immediately below the unsolvable cross bar 16 arranged. This connection element 38 is in the present case, for example, designed as a three-quarter rosette. The other two connection elements 38 are designed here as full rosettes, for example, which form the first vertical stem 12 fully grasp. Adjacent connection elements 38 each have the same, third distance here 42 on. The third distance 42 here also corresponds to the second length 28 of the second vertical post 14th .

On the second vertical post 14th is also a connection element here 38 intended. The connection element 38 on the second vertical post 14th is at the same height as the middle connection element 38 on the first vertical post 12 arranged, here directly below the non-releasable cross bar 16 . The connection element 38 on the second vertical post 14th can be used as a scaffolding rosette 40 , in particular as a three-quarter rosette.

The 2a , 2 B show a basic frame 44 in a perspective or side view. The basic frame 44 serves as a finishing element of a scaffolding to be arranged on the bottom. The basic frame 44 has two base stalks extending parallel to one another 46 on. The base stems 46 are through a base cross bar 48 and striving 50 inextricably linked. In particular, the two base stems 46 with the base cross bar 48 and welded to the struts. The base stems 46 each have an upper contact surface 52 on. The contact surfaces 52 of the two base stems 46 are in the direction of extension of the base stems 46 by a fourth distance 54 spaced from each other. The fourth distance 54 corresponds to the first distance 30th the lower support surfaces 18th , 24 of the scaffolding frame 10 from 1a , 1b . The scaffolding frame 10 can therefore with its two vertical stems 12 , 14th directly on the two base stalks 46 be put on. The base stems 46 each have a push-in or plug-in pin 34 for insertion into the receiving sections 36 the vertical stems 12 , 14th of the scaffolding frame 10 ( 1a , 1b) on.
