Weather protection for scaffolding

The invention relates to weather protection for scaffolding.

The fact that scaffolding used for renovation, painting or the installation and removal of windows in buildings should be usable in all weather conditions is a result of the building owners' schedule requirements.

However, since many days are rainy - especially in Central Europe - a weather covering for a scaffolding has already been proposed in a number of patent publications.

For example, DE-Al-32 44 905 contains a supporting structure for a weather cladding with which a protective tarpaulin can be stretched over curved console posts.

DE-Cl-36 09 785 already describes a cladding for scaffolding in which flat, rectangular cladding elements, which are made from a frame covered with plastic fabric or a thermal insulation mat, are clamped between profile rails and fastening bolts.

DE-Al-43 18 678 also shows a construction of a scaffold cover which, with a number of longitudinal and transverse profiles, forms a support for a tarpaulin stretched over it.

Finally, there is the German utility model G 93 95 738, which has a device for fastening tarpaulins to scaffolding using piping profiles for inserting corresponding piping thickenings provided on the edges of the tarpaulins. The fact that the scaffolding to be covered can also have a sloping roof surface can be seen from the German utility model G 75 14 453.

However, all of these protective rights have the disadvantage that the tarpaulin, once attached with comparatively great effort, cannot be easily removed from the frame supporting it for a few hours, for example in the event of a sun

The visor can be removed in the afternoon while at work and then reattached in the evening as a precaution against any rain showers during the night.

Instead, special scaffolding parts have to be attached to an existing scaffolding in a relatively complex manner and the tarpaulin has to be "pulled in place" in an improvised manner. Many of the structures known to date still require additional padding of sharp edges, which not only requires the scaffolding fitters to have special expertise in the type of padding, but also takes a considerable amount of time to implement.

The invention was based on the object of improving the previously known constructions in such a way that they can be mounted more quickly on an already existing scaffold, that the tarpaulin, once mounted, can be removed or put back in place for a short time without great effort and that at the same time avoids the previously known wind sensitivity and edge leaks of the known constructions.

According to the invention, this is achieved by a weather protection for scaffolding with the features of the main claim. The subclaims give advantageous embodiments of the invention.

It is particularly advantageous that the weather protection for scaffolding has a tarpaulin carrier which holds the tarpaulin on a rotatable axis so that it can be rolled out, whereby a profile to be anchored is provided on the free end edge of the tarpaulin on the scaffolding to be covered.

BOEHMERT *&^# BÖEHMEiftT

In a preferred embodiment of the invention, the tarpaulin carrier will have a solid housing that protects the tarpaulin (in the partially rolled-up state). In this rolled-up state, the tarpaulin can be transported to the place of use without having to fear damage. It is proposed that such a tarpaulin carrier be attached using fastening sleeves that are spaced apart along its length for attachment to a scaffolding beam running parallel to the tarpaulin carrier. The tarpaulin rolled up on the axle accommodated in the tarpaulin carrier housing is provided with a profile on its end edge that closes the tarpaulin carrier housing when in transport, so that no dirt that often occurs on construction sites, such as small rock particles or the like, comes into direct contact with the tarpaulin during transport.

Since in most cases the scaffolding does not have a cover directly above, it is proposed to attach another tarpaulin support to the upper end of a tarpaulin support which is vertical when assembled, via a joint, which offers a tarpaulin of the same length that can be rolled out. This tarpaulin is preferably rolled out in a position that is slightly inclined to the horizontal, and the inclination of which can also be adjusted to the respective roof slope, wall distance or the like by means of the joint.

A rubber foot or an end piece that can be attached using a wall nail or the like can be provided at the free end of this second tarpaulin support. The axis provided in the tarpaulin support housing for rolling up the tarpaulin is advantageously provided with spring catches in the manner of a roller blind, so that when the tarpaulin is

When rolled up, a spring tension remains on the tarpaulin, which flexibly cushions the wind. The free end of the tarpaulin can be attached to other scaffolding parts directly via the profile with bolts or ropes or similar, while at the same time the tarpaulin is stretched across the end profile, which relieves the load on individual attachment points.

In a preferred embodiment, in which a larger scaffold is to be covered, there is another tarpaulin support at the point where this end profile is attached, which in turn is provided on its side substantially opposite the tarpaulin pull-out opening with a complementary receiving profile to the end profile on the tarpaulin, into which the profile attached to the tarpaulin can be hooked. This results in a particularly rainproof cover, the edges of which offer no possibility of unfavorable weather influences, be it wind or rain, penetrating.

Finally, it is proposed that the arrangement consisting of two tarpaulin supports pivotably connected to one another via a joint be further designed in such a way that the vertical tarpaulin support can be pivoted out of the vertical about a pivot point in the middle of its length, in order to create ventilation in the inclined position of the side tarpaulin, if necessary in conjunction with a pivoting of the profile at the end of the tarpaulin. This inclined position can also be used to cover gable areas.

This ventilation can also be used in such a way that an upper part is swung away from the work wall to let light and sun into the work area, at the same time

However, dust and dirt are essentially kept within the scaffolding covered by the tarpaulins.

Further advantages and features of the invention will become apparent from the following description of a preferred embodiment with reference to the accompanying drawings.

The weather protection for a scaffold shown in Fig. 1 is provided with two tarpaulins 10, 12, which can be rolled in and out in a side tarpaulin carrier 14 and a tarpaulin carrier 16 covering the roof section. At the end of the tarpaulins 10, 12 there are profiles 18, 20, on each of which a ring 22 is provided in Fig. 1 purely as an example for hooking the profile into corresponding existing scaffolding parts. Of course, holes in the profile can also be used here for inserting bolts or for fastening the profiles with rope material. In a preferred embodiment shown in Fig. 6, the profile 18 at the end of the tarpaulin 10 is hooked into a corresponding profile groove 24, which is arranged on the outer housing 26 of the planet carrier 14.

In Fig. 2, a joint 28 is also shown, which is located in the extension of the extension of the tarpaulin carrier 14 at its upper end, wherein a corresponding joint carrier section 30 is arranged on the roof-side tarpaulin carrier 16 in the end region along one of its sides in such a way that the tarpaulin carrier presents the tarpaulin located therein while leaving as little free space as possible with the tarpaulin in the tarpaulin carrier 14, i.e. it preferably overlaps a little.

The angle between the individual tarpaulin supports 14, 16 can be adapted to the local conditions of the construction site. Fig. 2 also shows the scaffolding fastenings in the form of sleeves 32 for vertical scaffolding tubes.

In Fig. 3, the device of Fig. 2 is shown with an end and deflection piece 34, which in cases

BOEHMERT&· BOEHMERT

where angle adjustability is not necessary, gives the roof section greater stability.

In addition to the individual parts shown in Fig. 3, Fig. 4 also shows the axle 36 fitted in the housing 26 of the first planet carrier with its respective axle mounts 38 and 40, which are each inserted into the end region of the housing. These axle mounts can be screwed in or welded in.

Fig. 5 also shows an embodiment in which the lateral tarpaulin support 14 can be pivoted about a pivot point 42 located centrally along its axial extension.

In order to maintain its pivoting position, locking brackets 44 are provided, which can be attached from the end of the tarpaulin support housing 26 to the section 46 fixed to the frame, which remains stationary in order to support the roof support 16. It is also conceivable that such pivoting of side or roof tarpaulin supports is realized without realizing an arrangement of two tarpaulin supports coupled to one another, i.e. on a single roof or wall tarpaulin support.

Finally, Fig. 6 shows a cross-section through a tarpaulin support 14 and the sleeve for fastening to the scaffolding, showing the coupling of the tarpaulin coming from an adjacent tarpaulin support opposite the tarpaulin leading out of the tarpaulin support shown. Opposite the tarpaulin exit there is a profile groove 24 for hooking in the end profile 18 of the adjacent tarpaulin support.

At the same time, it is shown how these tarpaulins are provided considerably outside the already existing scaffolding beams, which are surrounded by the sleeve 3 2, so that "rubbing" of the tarpaulin on the already existing scaffolding is practically excluded for the stretched tarpaulins.
