Description

Field of application of the invention

The invention relates to a device for mounting suspended scaffolds on structures, in particular of suspended construction and repair scaffolding on the upper edge of building walls.

Characteristic of the known technical solution

From DE-OS 2552201 and 3401906 devices for attachment of Konsolgerüsten in the field of building openings are described. However, their application always presupposes that laterally or above the bearing point of the console are still stable wall parts that can absorb the traction. In addition, when attaching or dismantling this console or boom scaffolding on the wall back always a footprint must be present from which the rear anchorage elements are attached or removed by a second worker.

Well-known ladder gear consoles used in sliding constructions are used, to the anchoring in the monolithic concrete introduced female threaded sleeves with screws or continuous threaded bolts.

A disadvantage of these solutions is the dependence of the scaffold attachments on the arrangement of the openings, recesses and anchors in the building. In addition, the anchoring point must be accessible to the building during assembly or disassembly of the scaffolding parts.

In another type of attachment of suspension scaffolds, the suspension is done with open, angled or curved end hooks. These hooks have only a low load capacity and must be made adapted to each application. Your statically required little margin at the suspension point therefore prevents an independent assembly or disassembly.

Object of the invention

The aim of the invention is to provide a device for mounting of suspension scaffolds to buildings, which allows fast assembly of the scaffold with low cost and high security.

Explanation of the essence of the invention

The object of the invention is to develop a device for mounting suspended scaffolds on buildings, which can be used variably for different applications, the support forces of suspended scaffolds or working platforms on rigid, wall-like structural parts safely transfers at any point and the arrival or removal without access allows the support point. According to the invention the object is achieved in that the device consists of a Auflagerhalbrahmen and a fork-shaped locking lever with Anlegeblechen, a both parts rotatably and shear-resistant connecting hinge pin and a mounted on the locking lever assembly auxiliary device.

By lifting a scaffolding bracket or scaffolding bridge inevitable tightening a previously deflected stop rope attached thereto mounting device is moved horizontally and so brought the device in the favorable for mounting splayed location.

At the doing unterschwenkenden horizontal arms of the locking lever and the Auflagerhalbrahmens during spreading process engage in settling on the supporting wall vertical bearing forces and relieve the sling. The baffles fold frictionally against the load-bearing wall, thus ensuring a fine adjustment to the variable wall thicknesses. The generally favorable ratio of the large vertical forces to the small horizontal forces ensures a trouble-free framework suspension.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawings show

1: a side view of the device in basic position FIG. 2: a side view of the device during assembly FIG. 3: a side view of the device with attached scaffold bracket FIG. 4: a side view of the device with attached scaffold bridge FIG Device for wall profiling.

The inventive device according to FIGS. 1-5 consists of a Auflagerhalbrahmen 1 with a grid perforation, the

primarily assumes all support forces of vertically suspended scaffold bridges 12 or scaffolding brackets 13, the vertical forces directly and the horizontal forces indirectly via the locking lever 2 and the Anlegebleche 3 and 4 to the supporting wall 14 emits.

The support half-frame 1 is connected to the locking lever 2 by a hinge pin 7 rotatably and tensile strength and can

thereby not slide off the top edge of the supporting wall 14, even if the sum of all vertical forces is substantially greater than the sum of the horizontal forces.

Breadboard 8 in locking lever 2, in Auflagerhalbrahmen 1 and this offset hole grid in the Anlegeblechen 3 and 4

allow a finely graduated application of the device, as shown in Figures 3 to 5.

For mounting the device is an assembly aid device 6, consisting of a rope and a clamping device,

intended. The auxiliary assembly device 6 is connected on the one hand with the locking lever 2 and on the other hand with a sling rope 5.

The sling 5, the slightly eccentric struck the scaffold bracket 13 and the assembly auxiliary device 6 and

a cable deflection 10 is guided, is taken by a hoist when mounting the device. When lifting the

Device tightens the sling 5 and causes a spread of the support frame 1, the locking lever 2 and the Laying sheets 3,4. To limit the Spreizmaßes serves a locking lever. 9 When settling on a load-bearing wall 14 and the unloading of the sling rope 5, a forceful Heranklappen

of the locking lever 2 with Anlegeblech 3 and the support frame 1 with Anlegeblech 4 and scaffolding bracket 13, Fig. 1,2,3,5.

The analogous same processes take place when attaching scaffold bridges 12. A hole pattern 8 in the locking lever 2 allows adaptation to the changing ratio of male vertical

and horizontal forces at different thicknesses of the supporting wall 14. The ends of the horizontal arms of the

Bearing frame 1 and the locking lever 2 are rounded and therefore ensure even with unevenness of the top edge

the supporting wall 14 the safe operation of the device. With this solution can be single and in pairs

Scaffold bridges 12 or scaffolding brackets 13 are set down with a hoist at high altitudes. You can enter immediately

even if the point of contact is not accessible.

Particular advantages of the device according to the invention are the simple and quick installation, by the variable training

The use for a variety of applications without prior deployment planning and security even in difficult situations.
