Description

Device to configure a platform or scaffolding on an existing wall.

Object of the invention

The present invention relates to a device to set up a platform or scaffold on a wall existing, typically used to shape these structures in industrial chimneys.

Background of the invention

Scaffolding is currently known or platforms consisting of metal supports that rely on a firm base or hang on the corresponding wall, and support a plank framework that constitutes the scaffold floor or platform, also incorporating railings or quitamiedos.

These scaffolding, especially those supported, they are expensive and more if they have to reach considerable heights, as in the case of industrial chimneys, not adapting either perfectly to the contour of them by its curved contour.

On the other hand the hanging scaffolds need some upper poles that not in all cases can install, especially in industrial chimneys. Besides these hanging scaffolding are easily shaken and easily removed by the air, being suspended from cables on occasions of considerable length.

Other solutions such as specialized work in  height, with operators who are actually climbers, not they manage to send as much force as they lean on a scaffold, and They are also exposed to being shaken by air.

These inconveniences are remedied by use of the device of the invention.

Description of the invention

The device of the invention has a optimal constitution for easy, fast and economical installation on any wall, especially in the chimney constituents Industrial

According to the invention the device it comprises a plurality of supports, but at least two, which they support a network of planks or similar pieces that they constitute the floor of the scaffolding or platform.

The invention proposes to hang these supports by hooking it to a cable fixed horizontally to the wall in the height or height of use of the scaffolding, which does not support it on the ground or suspend from upper poles distant. In the case of an industrial chimney, this cable is will fix the chimney to the level in which the scaffolding is installed preferably surrounding it.

The supports are constituted as a bracket, with a lower support foot on the wall, an upper flange of hook to the cable and a cantilever beam on which the planks, including other profiles or crossbars that relate the previous elements to achieve structural rigidity necessary.

To stabilize the placement of the boards, the cantilever beam welds plates that increase the support surface while being held superiorly by middle of a profile that mounts height adjustable between two vertical pronunciations emerging superiorly from the stringer in  cantilever The height-adjustable mount allows the profile retainer adjust to the thickness of the planks.

In the external pronunciation of the two mentioned a strut fitted with a lower ear of passage and / or fixation is fixed of a tape as a socket, and also equipped with flanges intermediate and superior to fix between the different supports horizontal locking telescopic bars that extend stabilize the position of the supports with each other and constitute their Once the railings or scaffolding of scaffolding.

Finally, the device contemplates a additional security consisting of a cable that are tied independently to the wall or chimney, and to which the Operators through harnesses.

Brief description of the drawings

Figure 1 shows a view of the scaffolding configured according to the device of the invention.

Figure 2 shows an exploded view of the device of the invention.

Description of a practical embodiment of the invention

The device 1 of the invention comprises a plurality of supports 2, at least two, that support a lattice 3 of planks 4 that constitute the floor of the scaffolding or platform.

Each support 2 comprises a constituted bracket by a lower support foot 6 against the wall 7 in which it is fixed the scaffold or platform, a top 8 flange to engage in a horizontal cable 9 fixed to the same wall and slightly separated from the same at a suitable distance by means of a block 9a separators, a vertical profile 10 that relates the foot 6 and the flange 8, and a crossbar 11 constituting the cantilever of the bracket,  on which the boards rest, and which by means of a crossbar 12 inclined is related to profile 10 giving the necessary rigidity to the support. Usually wall 7 will consist of a chimney industrial, and the supports will be arranged radially, as well as the Cable 9 will surround the fireplace.

The crossbar 11 is provided with plates 13  welded horizontals that will support the planks 4, and two extreme 14.15 vertical pronunciations between which height-adjustable mounting a retainer profile 16 of the planks, which will allow you to adapt to different planks thicknesses, the height-adjustable fixing materializing by  sliding flanges 17.

In the outer pronunciation 14 it is plugged in and fix a strut 18 equipped with flanges 19 for fixing articulated, and at different heights, of telescopic bars 20 horizontal interlocking extension, which will constitute some railings or removers of scaffolding or platform. The fixation is articulated to allow the scaffolding or platform to adapt to curved contours as is usually the case with chimneys Industrial The struts are also provided with an ear 21 lower for the passage and / or fixing of a tape 22 as a plinth.

The interlocking extension of the bars 20 it is preferably carried out by means of pressure screws 23 or interns, and this interlocking will stabilize the position of the 2 supports, since it prevents them from opening or relocating each other.

On the other hand, the feet 6 of the supports have two horizontally aligned braces 24, to get a stand position perpendicular to the wall, while the planks 4 in contact with the wall adapt to the shape of the wall, for example if it is a chimney, adopting an arched shape Your song in contact with this area.

Similarly, flange 8 has a pin 25 of safety to ensure the support hitch.

Finally, the device of the invention is complete with another independent safety cable 26 and fixed to the wall, which operators are secured by harnesses, not represented.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
