CS207247B1 - Supporting plate for fixing the non-metal plate to the column - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to a carrier plate for attaching information and warning non-metallic plates to columns with fastening strips.

The previously known information and warning non-metallic tables could not be used universally, eg they could in no way be used in the field of open spaces around storage ducts in open terrain, heavy-current power equipment, railways, etc., fasten to the structure sufficiently firmly to withstand, for example, strong wind impacts. Therefore, it was necessary to use sheet metal plates in these areas, which were attached to the supporting structure by suitably adapted sleeves and screws or in another more complicated manner, for example by welding with the necessity of using an energy source and welding equipment. The sheet metal from which the sheets are made has to be further treated, usually by enameling, which considerably increases the cost. Another disadvantage of the use of these tables is the possibility of the enamel flake off in the event of a mechanical impact and a decrease in their readability by corrosive products, for example from screw joints or welds.

These drawbacks are eliminated by the support plate according to the invention, characterized in that the plastic support plate is attached on the inside by a plastic joint to a curved plastic support, provided on the inside with a layer increasing the coefficient of friction between the curved surface and the column, there is at least one tape-threading hole securing the support plate with the non-metallic plate to the column.

An advantage of the invention is that the information and warning non-metallic signs can be effectively attached to the poles at all, and thus can be used also in an open area exposed to strong winds. A further advantage is that the support plate according to the invention can be attached to the columns over a wide range of their diameters without adapting the attachment device to the perimeter of the respective column, as was necessary for the prior mounting of the metal warning and information plates. The coefficient of friction layer provided with the curved support to which the support plate is attached causes the desired roughening and hence the stability of the position of the support plate with the plate even under strong winds. The material, the plastic of which both the plate and the curved support and joint are made, is not subject to corrosion and is accessible and relatively inexpensive. Thus, the invention saves material that is scarce and expensive.

The invention is illustrated in the drawing.

and FIG.

FIG. 1 shows a top view of a polyethylene support plate 1 secured by a polyethylene joint 6 to a curved support 2 provided on its inside with a layer 3 of a chloroprene-silicon carbide mixture which increases the coefficient of friction.

FIG. 2 shows a side view of a support plate 1 fastened by a polyethylene joint 6 to a curved support 2. In the polyethylene joint 6 there are three holes 5 for insertion of strips 7 fastening the support plate with an unbound table to the column 4.

The invention can be used for simple immovable fastening of non-metallic plates to columns even in strongly windy environments.
