' According to the technology of the land, scaffolding made of wood or metal has the disadvantage that it swells when wet, with water and is not easy to break. These only have a lifespan of 4-5 years. Metal gratings have the disadvantage

a greater weight. Objects and waste can fall through the RosLo. The scaffolding coverings of the invention do not have these disadvantages.

The utility model application 295 06 072.7 discloses a scaffolding decking as non-prepublished prior art, which provides a weight saving compared to the known scaffolding deckings.

This scaffolding covering made of plastic material is structurally characterized by several, parallel, U-shaped, perforated reinforcement profiles and end caps, embedded in the longitudinal direction in the softening phase at around 180 °C, as well as with edge protection on all sides and, if necessary, with comb-shaped correction holders as internal reinforcement transverse to the longitudinal direction with spacer plates attached in pairs.

Compared to this state of the art, the scaffolding deck of the invention offers the advantage of further weight savings and structural simplification, also in its manufacture.

The subject of the invention is scaffolding decking.

The purpose of these is to make them from organic material, especially recycled material. They also have the purpose of being durable when handling and using them and, with sufficient static stability, to bring further weight savings.

The solution to the problem of the invention is defined in claim 1. The subclaims claim the alternative and preferred embodiment.

Cavities are spaces that can support the total weight of the scaffolding of the

j_5 invention. These are structural parts that are surrounded on all sides by plastic material and form these cavities, or these are full cavities made of foamed natural materials, or of such plastics or of expanded layered minerals that have a low specific weight.

A technical effect of the scaffolding covering of the invention lies in the increase in the static strength of the scaffolding covering of the invention while simultaneously reducing the weight and saving plastic material.

This technical effect is achieved for the first time because the scaffolding covering of the invention has a structural design of hollow spaces made of parts that are covered on all sides by plastic material.

These statically stable parts consist of '■ U-shaped profiles and channels, of inserts of strip iron as a combination element and which form such cavities.

This technical effect is also achieved by combining U-shaped, rectangular, parallel recesses of the framework of the invention in the longitudinal direction on the underside with these statically stable parts.

This technical effect is also achieved by creating hollow spaces by placing several box profiles on top of each other and connecting them homogeneously with webs. This technical effect is also achieved by creating hollow spaces from lightweight material that fills them.

The continuous production of the scaffold covering of the invention takes place, for example, on a rotary table system according to the state of the art with cycle times of 2 minutes.

The granulated material of 1-6 mmru is introduced into the mold and melted in the absence of air. The working temperature is 150-265 ⁰ C.

The calculated throughput capacity is 150-200,000 units/year.

The scaffolding covering of the invention is illustrated, for example, by Figures 1 a-c, 2 a-c, 3 a-c.

The figure " b " '· Oblique view, side view, top view.

Figure " c " : cross section with dimensions " in mm.

These dimensions demonstrate, for example, the optimal ratio of the cavities and parts to the plastic material that surrounds them.

Other structural conditions are also possible depending on the static stability of the cavities.

The scaffolding covering of the invention is given static stability and sufficient elasticity for practical use by the inserted reinforcement profiles. The edge protection on all sides, if necessary, ensures that the melted and coated parts do not bend or break off.

The structural design of the parts and their homogeneous insertion by melting or pressing results in surprising safety during transport and during installation and use in long-term continuous operation.

The perforation of the melted reinforcement profiles causes the technical effect of the optimal adhesion of the core profile from the parts in the scaffolding covering of the invention.

JH/m 18.08.95

The scaffolding deck of the invention has, for example, the following dimensions in mm" with a thickness of 35-48 mm:

1,500 x 290
2,000 x 290

2,500 x 290

3,000 x 290.

The total weight of a state-of-the-art wooden plank measuring 2,500 x 280 x mm is 19 kg.

In contrast, with the same dimensions, the total weight of the scaffolding deck of the invention is on average 12 - 15 kg.
The savings in weight and plastic material for covering the inserted structural parts are therefore considerable.

The U-shaped reinforcement profiles, for example, have the following dimensions:
20 x 26 x 20 x 15 mm
30 x 22 x 30 x 15 mm.

For example, the end caps have the following dimensions: 100 x 40 x 100 x 1.5 and 270 width.

A technical effect to reduce the penetration resistance of the introduced, molten plastic material lies in the number and arrangement of the punched holes in the reinforcement profiles.

For example, when viewed from above, there are

of the U-shaped profile as reinforcement

profile a parallel row of oval holes of 20 x 10 mm and round holes of 10 ram, with a side distance of 10 mm on each side and a distance of 30 mm between the holes.

This arrangement ensures sufficient adhesion and homogeneity of the introduced liquid plastic material in the scaffold covering of the invention.

The scaffolding deck of the invention offers the following advantages over the prior art:

The thickness of the scaffolding planks is 48 mm for wood and 45 mm for metal. The thickness is only 35 - 45 mm with the plastic material of the invention. The liter content is only 15 - 30 litres.

The scaffolding deck of the invention has a greater load-bearing capacity. The load-bearing

is 2-3 kN/m for wooden planks, however

for the scaffolding deck of the invention 4.5 - 5.0 kN/m ² .

The scaffolding covering of the invention is resistant to UV radiation and practically incorruptible and therefore indifferent to bacterial attack.

18.08.95

The scaffolding covering of the invention can be recycled. It has a non-slip and homogeneous surface without any branches like wood. It also has practically no risk of breakage.

A further advantage is that the scaffolding covering of the invention conserves resources due to its recyclability. It therefore does not require any landfill space.

Another technical advantage is continuous production with high throughput speed.
