Description

Vibrating floor with metallic casing, core and
Side edges

State of the art

Vibrating floors of the usual design are made of wooden boards. The dimensions of this wooden body are determined in particular by its load-bearing capacity and the
Technology of concrete block production.
The physical properties of the different types of wood are used appropriately.

High-quality vibrating floors are made primarily from sawn wood from tropical rainforest trees. In the industry, these products are referred to as hardwood vibrating floors.
When concrete blocks are manufactured automatically, these bases are required in considerable quantities in the concrete block factories. There are known factories in which up to ten thousand bases are in circulation.

Experience from the use of softwood lumber (pine, spruce, fir, larch) of European origin shows that in particular:

- the damping of the vibration energy,

- rapid surface wear,

- the dry joints between the individual boards and
- the fire load of natural sawn timber

to disadvantages for the products made from this material.

The state of the art is presented in the magazine "Betonwerk-Fertigteil-Technik" , issue 8/1992, pages 124 to 126, Bauverlag GmbH, Wiesbaden, as well as the offer and advertising materials of the major producers of

Vibrating floors. There are also known developments in which floors are made from recycled plastic.

Problems

The invention specified in claim 1 is based on the problem of reducing the surface wear of the vibrating floors in such a way that a considerable extension of their service life is possible.
The partially varying degrees of wear on the wooden surfaces reduce the quality of the stones produced.

It is also intended that vibrating floors that are no longer usable due to production consumption will be recycled and turned into fully functional production aids in the concrete block plants.

Otherwise, these used vibrating floors are to be considered as waste.

To date, it has not been possible to use new, but inferior and defective sawn timber, consisting of the main European wood species, for this purpose.

Attempts to prevent the use of wood from tropical rainforests as a possible raw material for vibrating floors by means of a functional material substitution have so far failed, partly due to economic considerations.

It should also be noted that the production of the conventional vibrating floor is complex.

Solution

These problems can be solved with the features listed in claim 1:

1. Metallic coating of a core with a
cuboid hollow body

and

2. a compressive force that exists in the core and
a pressure force opposite to this

Tensile stress on the metallic
surfaces of the casing, and for the
follow-up time is fixed,
be decisively mitigated.
20

These features are created during production by simultaneously exploiting such physical properties of the materials used as the shrinkage of the metallic coating as a result of the cooling of the previously heated metal, the generation of a compressive force by pressing wedges into the core and the further development of the already existing pressure and tension conditions by moistening the relatively dry heartwood with a hygroscopic substance and thus causing it to

swelling is stimulated. The metal on the casing can
vary in quality and strength on the ground.

Benefits achieved
35

This modified sandwich construction significantly improves the static properties of the product.

The invention ensures that the surfaces of the vibrating floor covered with concrete blocks wear out more slowly. This vibrating floor with its metal coating can itself be completely recycled.

Its production using new or used materials is technically possible both in a handicraft and industrial manner, with all gradations in between.

By using used vibrating floors for the wooden core of the new floor, more than 90% of it is reused. At the same time, this saves valuable landfill space for the transport of old floors to waste disposal facilities.

It is possible to do without high-quality tropical wood from the rainforests as a raw material for the soil. Coniferous sawn wood and especially old wood that is no longer suitable for material use can be used without restriction and thus as a material substitute in the core of the soil.

The quality of the concrete blocks produced with these vibrating floors is of a consistently high level.
The new type of vibrating floor is expected to improve the transfer of vibration energy to the concrete, which will have an impact on production times.

Example

An embodiment of the invention, in which the idea of recycling worn wooden vibrating floors comes into play, is explained using Figures 1 to 4. They show:
Figure 1 the cuboid-shaped metallic hollow body (1)

with edge (2),

Figure 2 Wear floor parts (core boards (3) and
side edges (4)),

Figure 3 two wedge-shaped wooden parts (5) of the vibrating floor,

Figure 4 the entire vibrating floor according to the invention with
Connecting elements (6).

A key point in achieving the inventive advantages of the vibrating floor in the manufacturing process while largely using parts of worn wooden vibrating floors for the core is its assembly.

The assembly process is characterized by the following special features:

1. Heating of the metal of the cuboid hollow body,

2. Insert the parts of the wear floor into the
hollow bodies,

3. Inserting the wooden wedges into the hollow body,

4. Pressing the wooden wedges into the core of the
vibrating floor,

5. Fastening the side edges to the vibrating floor,

6. Moistening the core in the vibrating floor in a

Glycerin solution, a wood preservative and a substance that inhibits rust formation.

This type of assembly achieves the compressive force in the core and the tensile stress on the casing.

As long as these forces exist on the vibrating floor in question, its performance characteristics exist.
