Reusable rain protection device for facade work

Description:

The invention relates to a reusable rain protection device for insertion into all conventional gutters, for facade work with and without scaffolding.

A particular problem arises when it suddenly rains during many facade work projects, especially when painting. The vertically falling raindrops hit the scaffolding boards and are sprayed onto the facade. This can cause damage, which means that the work has to be done again.

The present invention is therefore based on the problem of developing a device that can be used quickly and prevents water drops from hitting the scaffolding boards when it suddenly starts to rain, thus simultaneously protecting the facade work that has just been carried out from splash water.

This problem is solved with the features of the main claim. To do this, the rain protection device is inserted into the gutter. The device is held in the gutter by its own weight.

The rain protection device inserted into the gutter has a rolled-up rain protection film that can be quickly and easily unrolled while hanging over the scaffolding if necessary.

The rain protection device should be limited to a manageable size. A length of no more than 150 centimeters is recommended. Several rain protection devices can be lined up next to each other to protect the facade surfaces at risk from splash water. If two rain protection devices are lined up next to each other, a common scaffolding board length of 300 centimeters would be covered and protected.

If the rain protection device is no longer needed, the film is simply rolled back onto the device attached to it. The rain protection device is then ready for use again.

The rain protection device consists of a galvanized metal pipe that is cut along its entire length. This cut leads into the interior of the metal pipe.

The rain protection film that comes with the rain protection device is placed around a thinner galvanized metal pipe and welded. This thinner pipe with film is then pushed into the side of the thick metal pipe so that the film can be inserted through the cut in the thick pipe. The rain protection device is thus firmly anchored.

The two ends of the thick metal tube should now be closed in such a way that the inner tube and the film attached to it cannot slip out sideways. This would also make it easy to replace any damaged film.

The rain protection film to be used should be a waterproof and tear-resistant material in order to extend its service life. A transparency of the film would certainly be an advantage.

The length of the rain protection film should be limited to a total of 400 centimeters in order to ensure that the entire rain protection device is easy to handle and has an acceptable thickness. The resulting overall thickness of the device would also make it possible to use it in narrow gutters.

In order to ensure that the rain protection film hangs out evenly, the other end, which is not attached to the metal tube, is weighted down with an inserted metal rope. This flexibility of the rope reduces the risk of damage to the film, in contrast to a rigid metal rod.

For static reasons and to prevent a sail effect, there are no fastening options on the film that could be firmly connected to the frame.

Further details of the invention emerge from the subclaims and the following description of a schematically illustrated embodiment.

Figure 2: Application example for a reusable rain protection device for insertion into all conventional gutters for facade work with and without scaffolding.

Figure 1 shows the individual components of the rain protection device. A galvanized metal pipe (5) is used, which is

: it

The entire length (7) is cut into the interior of the cavity (6). The length of the metal tube (7) should be limited to 150 centimetres to allow easy handling. The thickness of the metal tube (8) must be in balance with the length (7) and the use.

A thinner galvanized metal pipe (13), which should also be limited to a length of 150 centimetres (14), must have a smaller outer diameter (16) than the inner diameter (9) of the metal pipe (5).

The metal tube (13) is completely inserted into the film loop (23) of the rain protection film (27). The loop (23) is created by welding (25) the film sides.

The difference between the outer diameter (16) of the tube (13) and the inner diameter (9) of the tube (5) must be at least the thickness of the film (24).

Now the thinner metal pipe (13) with the mounted rain protection film (27) is pushed into the thicker metal pipe (5), whereby the rain protection film (27) is guided through the pipe cut (6).

In order to fix the metal pipe (13) with the mounted rain protection film (27) in the metal pipe (5), both openings (4) are provided with a closure cap (31). The outer diameter (33) of the closure caps (31) is identical to the outer diameter (3) of the metal pipe (5).

Flexible plastic slats (32) fix the metal tube (13) in the metal tube (5) by clamping themselves in the metal tube (13).

The steel cable (53) is inserted into the small loop (28) and the two loop ends (28) of the rain protection film (27) are fastened by

welding (25). Therefore, the total length of the steel cable should be shorter than the width of the rain protection film. The total length of the rain protection film does not need to exceed 400 centimeters, since the endangered area of the facade is covered.

The rain protection film (27) can now be rolled up and down onto the metal tube (5).

A possibly damaged foil (27) can now be easily replaced as described above.

Figure 2 shows an example of the rain protection device (41) installed in Figure 1. The rain protection device (41) is inserted into the gutter (42) and hung over the scaffolding rod (40). The rain protection device (41) is held in the gutter (42) by the total weight of the two metal pipes (5) and (13).

The rain protection film (27) is evenly suspended by the weight of the flexible steel cable (53).
