Description

Scaffolding system with a scaffolding element and method for stiffening a scaffolding system

Technical area

The invention relates to a scaffold system with a scaffold element, and to a method for setting up a scaffold system.

In the field of civil engineering, it is necessary to carry out work at different heights. For this purpose, there are a large number of different scaffolding elements which can be arranged one above the other to form a scaffold system, so that different working heights or working positions can be achieved by arranging different scaffold elements one above the other. In particular, when setting up or dismantling slab formwork systems such scaffolding systems are particularly useful. Furthermore, such scaffolding systems are used to remove the loads of such formwork.

State of the art

Scaffolding elements are known from the prior art, but these scaffolding systems have the disadvantage that in many cases a combination of different scaffolding elements with working positions at different heights is necessary to set approximately the ideal working position.

Furthermore, the passage height between two stacked scaffolding elements, in particular due to the height of the individual GerusteJemente, sometimes less than 1.8 m, which people can only go through in a stooped posture and the risk of accidents increases by eventual abutment with cross connections.

EP 0 014 623 A1 discloses a scaffolding system in which the height of the floor defining the working position is fixed.

DE 1 740990 U discloses a Gerüsteiement in which a horizontally arranged longitudinal tube can be inserted into a vertically displaceable support tray and secured there by means of a screw bolt. Illustration of the invention

The invention has for its object to provide a scaffolding system that solves the known problems of the prior art and also has a simple structure. Furthermore, this advantage should be achieved in a method for setting up a Gerεstsystems.

The solution of this problem is on the one hand by the scaffold system described in claim 1.

Accordingly, the scaffolding system comprises at least two scaffolding elements, which comprise two substantially mutually parallel support and at least two stiffening elements for stiffening the parallel support assembly, wherein the skeleton element has exactly one cross-connection element which is fixed between the straps and connects, and wherein the stiffening elements attached to the cross-connection element. In use, the carriers are placed vertically to the ground and all elements of a scaffold element, so the carrier, the stiffening elements and the cross-connecting element, are located approximately in a plane. In preferred use, two or more scaffolding elements are arranged in parallel planes one behind the other and stabilized by lateral stiffening or "Verschwertungen" between the scaffolding elements, so that tipping over the scaffolding elements is prevented.

In this way it is particularly advantageously possible with a scaffolding element to provide a stable scaffolding system which has only one cross-connection element. By attaching the stiffening elements to the cross-connection element, it is also possible to provide a particularly stable framework element in which the stiffening elements do not span the framework element between the two supports and do not cross over, but in which the stiffening elements only extend from the support to the cross-connection element ,

Thus, a substantially barrier-free passage between successively arranged Gerüsteiementen is provided particularly advantageous because only one cross-connection element is present, and the stiffeners are arranged laterally. By means of the scaffold element according to the invention, it is furthermore possible to use less material for the reinforcing elements with high stability of the scaffold element and thus to save costs and weight. The weight saving also allows ergonomic handling of the scaffolding element according to the invention during assembly and disassembly.

The cross-connection element is arranged asymmetrically in the longitudinal direction of extension of the carrier. In this way it is possible, by upside down identical scaffolding elements, the To arrange Querverbindungsetement according to requirements at different heights and to realize particularly high passages between stacked scaffolding elements,

The scaffold elements can also be arranged one above the other to form a scaffold system. In order to connect the framework elements, it has proven to be particularly advantageous to provide at least one support end with at least one opening into which a connection element can be introduced. In this way, it is particularly advantageous possible to arrange a plurality of scaffolding elements with differently oriented, asymmetrically arranged cross-connection elements one above the other and to connect them.

According to a development it is provided that the stiffening elements are arranged so that a passage between the attachment points of the stiffening elements is recessed on the cross-connection element. In this way, it is particularly advantageous possible, when several Gerüsteiemente one behind the other, that a barrier-free passage between the Gerauteniementen is made possible. At the end of such a passage, that is on the foremost and / or the rearmost scaffolding element, a securing element, in particular a railing, can be arranged. It is possible, the securing element easily releasably attached to the cross-connection elements or on the carriers. In this way it is particularly advantageous possible to prevent the falling of persons or objects.

As already mentioned, a scaffold system is created by arranging several scaffold elements one above the other. It is particularly advantageous possible to vary the working height and the passage height between the Gerauteiementen by the asymmetrically arranged cross-connecting element is placed in accordance with the upper or lower half.

According to a particularly preferred development, a walk-on support surface can be arranged between two transverse connecting elements of two scaffolding elements arranged substantially parallel to the floor. In this way, it is particularly advantageous possible to provide an area on which people stand or tools can be stored to provide.

The object underlying the invention is further achieved by a method for setting up a scaffold system, in which initially a first scaffolding element with two carriers and an asymmetrically arranged cross-connection element, to which a large and a small passage area adjoin between the carriers, is placed. Subsequently, a second Gerusteiement, which two carriers and an asymmetrically arranged cross-connecting element, which is adjacent between the carriers a large and a small passage area, connected to the first scaffolding element, wherein the second scaffold element with respect to the first scaffold element a different orientation of the asymmetrical cross-connection urigsetements, so that the two large passage areas adjacent to each other. Alternatively, it is also possible to arrange the two small Durchgaπgsbereiche adjacent to each other. These two steps can be repeated as often as desired until a scaffold system is erected at the desired height, it not being necessary to mention that when arranging the third scaffolding element over the second one it is only possible to arrange two small passage areas adjacent to each other or one small and one large passageway area adjacent to each other. In this way, it is in any case advantageously possible to set up a scaffolding system in which an ideal working height or working position can be achieved by skillful arrangement of the asymmetrically arranged cross-connecting element.

Structural elements;

Detailed description of preferred embodiments of the invention

1 shows two framework elements 10 arranged one above the other to form a framework system 20, the framework elements 10 each having two supports 12 arranged in parallel. The beams 12 are interconnected with a cross-link 16, the cross-link 16 in the illustrated embodiment being arranged asymmetrically in the longitudinal direction of the beam 12, i. in the "upper" or "lower" half of the carrier 12. Two superimposed carriers 12 are connected to each other via a connecting element 24, not shown in FIG.

From the carrier 12, stiffening elements 14 extend at an angle to the transverse connecting element 16, in this way the rigidity of the framework element is increased. In this case, a stiffening element 14 extends from an area above the transverse connecting element 16 at an angle from each carrier 12 to the transverse connecting element 16 and a stiffening element 14 extends itself from an area below the cross-connection element 16 in a wink! from each carrier 12 to the cross-connection element 16.

The stiffening elements 14 are welded to the cross-connecting element 16 and the carrier 12. Alternative forms of attachment, such. B. by screws, rivets or the like, are also possible.

As shown in Fig. 1, a plurality of scaffolding elements 10 to a scaffold system 20 can be arranged one above the other. In this case, it is possible, in particular in the case of asymmetrically arranged transverse connecting element 16, to arrange two scaffold elements 10 one above the other in such a way that with identical scaffold elements 10, the transverse connecting element 16 is aligned differently. This is done by reversing the arrangement of the scaffold elements 10, in this way it is possible to create a large or a small or a middle passage area between two adjoining scaffolding elements 10 as desired. In this case, the large passage area is created by the scaffolding elements 10 are arranged one above the other so that the large passage areas of the scaffolding elements 10 adjacent to each other. A small passage area can be created between the scaffold elements 10 in the scaffolding system 20 by arranging the scaffold elements 10 one above the other so that the small passage areas adjoin one another. A central passage area between the scaffold elements 10 of the scaffold system 20 can be created by arranging the scaffolding elements 10 one above the other with the alignment of the asymmetrically arranged cross-connection element 16.

Furthermore, a walkable support surface between two substantially successively arranged scaffolding elements 10 can be arranged. The bearing surface is thereby supported on the transverse connecting element 16 in such a way that the bearing surface is held securely and passably in both arrangement orientations of the framework element 10.

By arranging a plurality of scaffold elements one above the other and / or behind one another, it is possible to provide a scaffolding system in which different through heights (small, medium, large) can be realized between the skeleton elements arranged one above the other.

In order to achieve a high degree of flexibility in the representable working or passage height, compatible scaffolding elements 10 at different heights are possible. Thus, for example, scaffold elements 10 having a height of about 1.8 m, 1.2 m or 0.9 m, wherein the Querverbindungseiement 16 each corresponding asymmetric, preferably about one third of the height of the carrier 12, is arranged. Thus, for example, when arranging two 1.8 m high beams with differently aligned cross-connection elements one above the other (large passage area), a clearance height of over 2 m arises of the computational 2.4m passage height (2 x 1.2m) still the height of Querverbmdungselemente 16 must be deducted

A Sicherungselemeπt 19 in particular a Gelander is to arrange at the end of a passage between the stiffening elements 14 or the wearers 12 to avoid personal injury For the securing element 19 is a Fsxierstelle 22 on both sides of the cross-connecting element 16 on the stiffening element 14 and / or the carrier 12th Insofar as the securing element 19 is attached to the stiffening element 14, care should be taken that this long ver is bar, so that it attaches to the stiffening element 14 on both sides of the transverse connecting element 16

In a gantry system 20 with skeleton elements 10 arranged one above the other, a connecting element is attached between two girder elements 10 in order to fasten the girder elements arranged one above the other

In FIG. 2, an example of such a connection element 24 is shown. The connecting element 24 is inserted into the preferably cross-sectionally shaped carrier 12 until it bears against an import limiter 28, which has a larger diameter than the carrier 12, and a locking device 26 in FIG a locking receptacle formed on the support 12 engages The skeleton element 10 to be arranged on the skeleton element 10 provided with the connecting element 24 is connected in an analogous manner to the connecting element 24. In this way, the flexible arrangement of the skeletal elements 10 is ensured one above the other to form a skeleton system 20

Alternative attachments between the carrier 12 and the connecting element 24 are also possible. For example, the connecting element 24 can be locked or fastened to the carrier 12 by means of a staking bolt, a clip-on plug, a latching element or the like

The ends of the carriers 12 and the connecting elements 24 are dimensioned such that spindles arranged on the bottom can be screwed in to balance the height of the carrier in both the carrier 12 and the connecting elements 24. In this way, a skeleton element can be aligned on uneven ground the height can be set exactly Such spindles are available in the construction industry bar

FIG. 3 shows a further embodiment of a framework element 10 according to the invention, the same or similar elements being designated by the same reference symbols. FIG. 3 shows a framework element 10 whose carrier 12 has a lower La elongation than 1.4 m, preferably approximately 0.9 m or 1.2 m . exhibit. In this framework element 10, it has proved advantageous to carry out only one reinforcement element 14 in analogy to that described on FIG. 1 on each support 12. This is, with asymmetrically arranged transverse connecting element 16, preferably to be carried out on the side of the transverse connecting element 16 on which the longer part of the carrier 12 extends. However, the embodiment of Fig. 3 may also have two stiffening elements on each side.

Alternatively, in all embodiments it is possible to arrange the stiffening element 14 on a support 12 of the framework element 10 below and on the other support 12 the stiffening element 14 above the transverse connection element 16.
