Description

The present invention relates to a bracket scaffolding element for attachment to a bearing bar of a reinforcement, comprising a bearing bracket with a placement spur, a bearing bracket and a profile rail. In addition, the invention relates to a bracket frame comprising at least two bracket frame elements according to the invention.

BACKGROUND OF THE INVENTION AND PRIOR ART

There are a number of different types of scaffolding to secure buildings that are to be erected. In buildings, scaffolding is usually used, which stands on the ground and is attached to suitable safety anchors on the outer wall of the building in order to prevent the scaffolding from tipping over. An essential prerequisite for a scaffolding is therefore a stable and level subsoil.

If such a substructure is not available or if work has to be carried out at a specified height, mobile bracket scaffolding offers an alternative. Bracket scaffolding is scaffolding in which brackets are hung on the outer wall, e.g. in suspension loops embedded in concrete, which must be removed after the scaffolding has been dismantled. A console is usually a galvanized triangular steel construction. For anchoring to the building, bracket scaffolding usually includes suspension loops or suspension shoes. Such scaffolding is mainly used up to a height of about 120 meters. Heights beyond this are ineffective because of the effort to be secured.

In contrast, there is no special scaffolding for the construction of walls, reinforced soil and slope stabilization. The known bracket scaffolds do not allow the protective scaffold brackets to be securely anchored to reinforced steel mats and the like.

It is currently only possible to secure this work by using personal protective equipment and safety ropes.

BRIEF DESCRIPTION OF THE INVENTION

The object of the present invention is therefore to provide bracket scaffold elements for a bracket scaffold which can be securely fastened to differently inclined reinforcements, which can be assembled and disassembled quickly and which significantly increase occupational safety.

• eine Tragkonsole mit einem Aufsetzsporn,
• eine Auflagerkonsole,
• eine Profil schiene,

wobei auf der Auflagerkonsole ein Gerüstboden anbringbar ist, wobei Tragkonsole, Auflagerkonsole und Profilschiene ein Dreieck einschließen, wobei die Tragkonsole mit dem Aufsetzsporn an einem Tragstab aufsetzbar ist, wobei die Tragkonsole am Tragstab fixierbar ist, wobei die vom Dreieck eingeschlossenen Winkel veränderbar sind.This problem is solved by a bracket frame element for fastening to a bearing bar of a reinforcement, comprising

• a support bracket with a spur,
• a support bracket,
• a profile rail,

wherein a scaffolding base can be attached to the support bracket, wherein the support bracket, support bracket and profile rail enclose a triangle, the support bracket with the mounting spur can be placed on a support rod, the support bracket can be fixed to the support rod, the angles enclosed by the triangle being variable.

The console frame element according to the invention can thus also be fixed to reinforcements or supporting rods on inclined slopes. The inclination of the support bracket can be adjusted in such a way that it allows a horizontal position. A board attached to the support bracket can therefore also be adjusted horizontally in slopes of different steepness.

In addition, the bracket scaffolding element enables a bracket scaffold to be set up very quickly with the aid of the mounting spur, in that the mounting spur is placed on a support rod. The placement spur is preferably a hook-like hanger. The hanger can be U-shaped so that it can be hung particularly easily on a rod.

In order to prevent the placement spur from detaching from the supporting rod if the console frame element is inadvertently lifted, the frame can include a securing element. This secures and locks the bracket scaffold element to the reinforcement.

The bracket frame element according to the invention can be mounted on a reinforcement without any tools. In addition, the bracket scaffolding elements can be transported very easily and thus offer an extremely flexible option for erecting a protective railing and fall protection.

In a particularly preferred embodiment variant, the support bracket is fixed detachably and articulated to the profile rail, the support bracket to the support bracket and the support bracket to the profile rail, with the support bracket being displaceable along the profile rail.

This results in a mobile, foldable console frame element, which can be stored and transported in a very space-saving manner. To put it more precisely, the support bracket and the support bracket can be folded in essentially parallel to the profile rail for transport.

The articulated connections can be realized, for example, by means of through-openings or holes on the support bracket, the support bracket and the profile rail, into which bolts or threaded pins can be introduced.

Furthermore, a trolley can be attached to the profile rail, to which a bearing piece is preferably detachably attached. The roller hanger and the bearing piece connect the support bracket to the profile rail. In this embodiment variant, a stop is fixed to the profile rail, which stops the roller hanger sliding along the profile rail in one direction. The support bracket is preferably fixed in an articulated manner on the bearing piece.

With the help of the trolley, the bracket frame element can be folded out or folded in very quickly. The folding mechanism results from the respective articulated connections of the support bracket, support bracket and profile rail, which fold in and out when the roller apparatus is moved along the profile rail.

The position of the stop is particularly preferably adjustable along the longitudinal direction of the profile rail. The angle between the profile rail and the support bracket can be adjusted by adjusting the stop. This means that the inclination of the support bracket can be adjusted using the stop. If the bracket frame element is mounted on an inclined reinforcement, this inclination can be compensated for in such a way that the support bracket is placed horizontally on the mounted and folded out bracket frame element. A scaffolding deck, which is mounted on the support brackets of at least two bracket scaffolding elements arranged at the same height at a distance, can therefore have a horizontal, walkable standing surface even on sloping slopes.

Preferably, the profile rail can also be fixed to the support bracket at different positions in the longitudinal direction thereof. For this purpose, the support bracket can comprise a plurality of through-openings arranged one below the other in the longitudinal direction, to which the profile rail can be mounted using connecting means. With the through-openings it can are, for example, laterally opposite holes or bores, through which the connecting means, for example a bolt or threaded pin, can be inserted. The support bracket can then have holes in several positions. This allows the angle between the support bracket and the profile rail to be changed, which in turn results in a change in the inclination of the support bracket.

In summary, the angles enclosed by the triangle of the bracket frame element can be changed and the angle of inclination of the bracket frame element can be adjusted as a result on the one hand by adjusting the stop on the profile rail and on the other hand by changing the fixing position of the profile rail on the support bracket.

Furthermore, the securing element of the bracket frame element can comprise two securing plates which are fixed to the support bracket. The securing plates are preferably mounted laterally on the support bracket. When the bracket frame element is unfolded, the securing plates move with it in such a way that they encompass the mounting spur when the bracket frame element is completely unfolded. Thus, after the placement of the placement spur on a support bar, the bracket frame element is secured to the reinforcement at the same time as the bracket frame element is folded out, in that the securing plates encompass the support bar and the placement spur from the underside. The locking plates can have an opening in which a part of the landing skid can be received. The opening is preferably designed in such a way that as the bracket frame element is unfolded, the mounting spur moves further and further into the opening and is completely surrounded by the securing plates when the bracket frame element is fully unfolded. By attaching two safety plates on both sides of the support bracket, double safety can be guaranteed.

In a further embodiment variant, the support bracket includes a fork-shaped foot spur. This can be fixed at different heights in the longitudinal direction along the support bracket. When assembling the bracket frame element according to the invention, it can be placed on the foot spur, with the foot spur bearing the entire weight of the bracket frame element during assembly. After assembly, a movement of the bracket frame element around an axis that is perpendicular to the support bracket is limited by the foot spur. Since the foot spur can be adjusted in height along the support bracket, its distance from the touchdown spur be adapted to the respective reinforcements to which the bracket scaffolding element is to be mounted.

To fix the spur, the support bracket can have a through-opening extending in the longitudinal direction. The foot spur can then be fixed at any position along this passage opening with a connecting means on the support bracket.

In addition, the console framework element can comprise a support fork with a fork-shaped end and an angled end. The angled end can be attached to the bracket frame element and the forked end can be attached to a reinforcement. The fork-shaped end allows attachment to a reinforcement, which essentially corresponds to the attachment of the foot spur. In order to enable the angled end of the support fork to be hung on the support bracket, the support bracket can preferably have a safety clip on both sides. The angled end can then be easily hooked into the safety clip. The support fork prevents or restricts lateral movement of the bracket frame element. Thus, the bracket frame element is secured against lateral pivoting.

In order to prevent the support fork from falling down when it is not suspended, it can be connected to the bracket frame by means of a safety cable, for example. There is preferably an attachment on the support fork with a through-opening, to which the safety cable can be attached.

Furthermore, the support fork can serve as a transport safety device when the bracket frame element is folded in. For this purpose, the at least one securing plate can include a through-opening, through which the angled end of the support fork can be pushed on the folded-in console frame. This prevents the support bracket from being displaced along the profile rail and the bracket frame element cannot be unfolded accidentally, for example during transport.

In a further embodiment variant, the profile rail comprises a toe board and at least one bracket, preferably at the height of the support bracket. The height of the toe board and bracket can be varied in the longitudinal direction along the profile rail in order to allow boards, fall protection or safety nets to be attached as flexibly as possible. It can Several brackets can also be attached along the profile rail in order to be able to attach a wide variety of fall protection devices. For example, two brackets can be fixed along the profile rail as a breast and middle weir. The stirrups and the toe guard can also include through-openings on which carabiners can be hung. Additional self-belays can be attached to these carabiners.

The present invention also relates to a bracket frame comprising at least two bracket frame elements according to the invention.

A bracket scaffold, which includes the bracket scaffold elements according to the invention, greatly facilitates work and protection against falling objects, for example when erecting embankments or securing slopes, and at the same time can be moved manually. In addition, the bracket scaffold requires very few tools for assembly, including securing to the reinforcement. Thus, on the one hand, occupational safety is significantly increased and, on the other hand, quick assembly and disassembly possibilities are created.

Furthermore, the invention relates to the use of bracket scaffolding elements according to the invention or a bracket scaffold for erecting a protective railing and fall protection when erecting protective walls, ramparts and slope protection.

As in Figures 1, 2 and 9 As can be seen, the bracket frame element according to the invention comprises three basic components, which are a support bracket 1 , a support bracket 2 and a profile rail 3 . As is usual with bracket scaffolding, the support bracket 1, the support bracket 2 and the profile rail 3 enclose a triangle. The angles α, β, γ enclosed by the triangle can be changed, so that the inclination of the support bracket 2 can also be varied. Therefore, the bracket scaffolding element according to the invention can also be used as protective scaffolding on slopes of different inclinations when erecting reinforced earth, slope protection or the like. The inclination of the support bracket 2 can be changed by adjusting the angles α, β, γ. In this way, the bearing bracket 2 can be adjusted horizontally in gradients of different steepness. So that the support bracket 1 can be placed on a support rod of a reinforcement or the like in a simple and quick manner, it comprises a placement spur 4. The placement spur 4 preferably has as in figure 5 shown the shape of a hook-like hanger. The hanger can be designed in a U-shape, for example.

In order to secure the support bracket 1 on the support rod, the support bracket 2 comprises at least one securing element 5. The securing element 5, which is 3 is shown can be attached to the end of the support bracket 2 connected to the support bracket 1 . The support bracket 2 particularly preferably comprises two securing plates 5 which are mounted on opposite sides of the support bracket 2 .

A scaffolding deck can be attached to the support bracket 2. By fixing at least two bracket scaffolding elements at a certain distance at the same height on a reinforcement, a safety base can therefore be attached and fixed to the bracket scaffolding elements very easily and inspection of the scaffolding is made possible. The profile rail 3 particularly preferably comprises as in Figures 1, 2 and 9 shown at the level of the support bracket 2, a toe board 11, to which the scaffolding floor or a board can be fixed. The scaffolding deck can be placed horizontally by varying the angles α, β, γ.

In a particularly preferred embodiment variant, the support bracket 1 is fixed to the profile rail 3, the support bracket 1 to the support bracket 2 and the support bracket 2 to the profile rail 3 in a detachable and articulated manner, and the support bracket 2 is designed to be displaceable along the profile rail 3. These connections allow the console frame element to be folded in, as shown in 9 shown. To put it more precisely, the support bracket 1 and the support bracket 2 can be folded essentially parallel to the profile rail 3 for transport. As in 9 as can be seen, the securing element 5 can move with the support bracket 2 when the bracket frame element is folded in, to which it can be fixed. The securing element 5 therefore detaches from the mounting skid 4 when it is folded in and releases it. The Aufsetzspur 4 can then be removed from the support rod.

The profile rail 3 can preferably be fixed at several points on the support bracket 1 . The angle α between the support bracket 1 and the profile rail 3 can also be adjusted due to the different fixing points. The different fixing points on the support bracket 1 can be designed, for example, as through openings or holes, which are located on both sides of the support bracket 1 and through which a bolt or threaded pin can be guided in order to connect the profile rail 3 to the support bracket 1 in an articulated manner.

Furthermore, the profile rail 3 can comprise a trolley 6 and a bearing piece 7 detachably attached thereto (see FIG Figures 1, 2 and 9 ). The trolley 6 and the bearing piece 7 can form the connecting link between the support bracket 2 and the profile rail 3 . In addition, the profile rail 3 includes a fixable stop 8, on which the trolley 6 stops. The support bracket 2 can be fixed to the bearing piece 7 in an articulated manner. The trolley 6 can be moved along the profile rail 3 and allows the bracket frame element to be folded in as shown in FIG 9 shown.

The stop 8 stops the roller hanger 6 at a specific position in the longitudinal direction of the profile rail 3. The stop 8 is preferably attached at any point on the profile rail using a connecting means such as a screw. The inclination of the support bracket 2 and thus also of a scaffolding deck that can be placed on the support bracket 2 can be adjusted via the position of the stop 8 . To put it more precisely, the angle γ between the profile rail 3 and the support bracket 2 can be changed by adjusting the stop 8 in the longitudinal direction along the profile rail 3 .

The bearing piece 7 allows an articulated connection of the support bracket 2 with the trolley 8. As in 8 shown, the bearing piece 7 can be rounded on the side facing the support bracket 2 in order to allow the support bracket 2 to rotate about the bearing piece 7 . In addition, the bearing piece 7 can have through-openings 18 such as holes, into which connecting means can be introduced in order to connect the bearing piece 7 to the roller apparatus 8 and the support bracket 2, preferably in a detachable manner. A bolt or threaded pin, for example, can be used for the articulated connection between the bearing piece 7 and the support bracket 2 .

By the trolley 7 being moved or rolled away from the stop 8 along the rail 3, the support bracket 2 hinged to the trolley 7 and the support bracket 1 hinged to the support bracket 2 also move in the direction of the rail. Thus, the console frame element according to the invention as in 9 shown can be folded and transported very easily and space-saving.

Furthermore, the bracket frame element can have a forked foot spur 9 on the support bracket 1 . The foot spur 9, which in the Figures 1, 2 , 9 and 6 is shown is preferably attached to variable positions along the support bracket 1. For fixation with the help of a connecting means, the spur 9 can in turn comprise through-openings 14 such as holes. The support bracket 1 can also be used as in figure 5 shown comprise an elongate through opening 15 along which the spur 9 can be attached. With the help of the foot spur 9, the bracket scaffold element can be placed on a reinforcement and carry the entire weight of the bracket scaffold element during assembly of the scaffold. In addition, the foot spur 9 prevents the bracket frame element from twisting about an axis in the assembled state, which is perpendicular to the support bracket 2 or to a scaffolding deck attached thereto.

When assembling the bracket scaffolding element according to the invention, the folded scaffolding can first be placed on a reinforcement using the foot spur 9 . Thereafter, the Aufsetzspur 4 can be attached to a support rod. The bracket frame element is preferably folded out only after this. The trolley 6 can be moved in the direction of the stop 8, with the articulated support bracket 2 also moving automatically. The secured to the support bracket 2 fuse element 5, which is is preferably two locking plates 5, also pivots as in 9 shown with and encompasses the Aufsetzspur 4 from the bottom. As a result, the support bar is essentially surrounded by the securing element 5 and the positioning spur 4 and the scaffold bracket is locked and secured to the reinforcement. The safety can only be released by folding the bracket frame element back in. Then the preferably two locking plates 5 move again automatically with the support bracket 2 and release the support rod.

As in 3 As can be seen, the securing plates 5 can comprise an opening 20 which is adapted to the shape of the placement spur 4 and in which a part of the placement spur 4 can be accommodated. This opening 20 enables a safeguard against unintentional detachment of the bracket frame element from the support rod.

In addition, the console framework element can comprise a support fork 10 with a forked end 10' and an angled end 10'', which in 2 and 7 is shown. The angled end 10 "can be hung on the support bracket 2 and the fork-shaped end 10 'can be fixed to a reinforcement. The support bracket 2 preferably comprises as in 4 shown preferably on both sides a safety clip 17, in which the angled end 10" of the support fork 10 can be hung. Because the fork-shaped end 10" of the support fork 10 is fixed to the reinforcement, the bracket frame element cannot pivot laterally. In order that the support fork 10 does not fall down during assembly and disassembly of the bracket frame element, it can be connected to the bracket frame element with the aid of a rope or thread, preferably a safety rope. For this purpose, the support fork 10 can be used as in 7 shown include an attachment 13 for attaching the cable.

During transport, the support fork 10 can be used as a transport lock. For example, the at least one securing plate or preferably two securing plates 5 on the support bracket 2 can include a through-opening 19 through which the angled end 10" of the support fork 10 can be pushed when the bracket frame element is folded in. This prevents the bracket frame element from folding out.

In a further embodiment variant, the profile rail 3 comprises a toe board 11 and at least one bracket 12, preferably at the height of the support bracket 2. Boards, fall protection devices or safety nets can be attached to the toe board 11 and bracket 12. Preferably, toe board 11 and bracket 12 include through-openings or holes to which additional fall protection devices can be attached. For example, carabiners can be hung in the passage openings. The carabiners can be used for additional self-belaying by people working on the bracket scaffold. In addition, the safety rope to which the support fork 10 is attached can also be attached to the toe board 11 .
