Abstract

Protective device against mechanical damage to tree trunks using renewable raw materials in the form of prefabricated mats, characterized in that a coarse-meshed mat made of natural fibers equipped with rod elements is arranged on at least two separately attachable tubular spacers made of flexible material and arranged in a ring on the tree to be protected is.

Description

The invention relates to a protective device against mechanical damage of tree trunks using renewable raw materials in the form of prefabricated flexible mats, which are arranged if necessary on a tree trunk to be protected.

This invention is needed above all for construction measures in the road and / or walkway area to protect the trees present there.

Devices for protecting trees are already known from the patent literature. However, most solutions are concerned with the protection of very young trees in order to protect them from wild game or other mechanical damage in the first years.

This is already how the AT 162008 already with a solution for tree protection against game damage. This solution consists of a laid around a tree trunk lattice, wherein the grid consists of wooden slats with spacer bodies arranged therebetween, wherein the individual elements have holes, these elements are threaded by means of a retaining wire and so a slatted frame is formed. In order to prevent the lattice grid from having to be constantly changed as a result of the stem growth of the tree, a solution has been developed which makes it possible to readjust the circumference. For this purpose, the ends of the retaining wires are bent parallel to the tree trunk axis, wound on a bolt, spirals, which partially develop as the trunk circumference increases. Thus, the adaptation to the changing trunk circumference of the tree is given and a constant change of the slat grating is no longer necessary.

Disadvantage of this solution is the costly use of materials and the time-consuming preparation for the production of the slatted base. He is also not suitable for the desired use of damage caused by construction, since the slats can be removed if damaged by construction machinery and the tree can now be damaged by the retaining wire. Neither the slats nor the retaining wire have the required elasticity to withstand the forces of force attack, for example, by a construction machine.

It is therefore an object of the invention to provide a device which overcomes the disadvantages of the prior art and which is suitable both locally and preassembled to be adapted to the actual conditions of tree growth to withstand high mechanical stresses and quickly and be flexibly mounted and dismounted.

According to the invention the object is achieved by the features of the main claim, wherein the advantageous embodiments are described in the subclaims.

Thereafter, there is a protection against mechanical damage of logs from prefabricated flexible mats, which are made using renewable resources. For this purpose, a coarse-mesh mat made of natural fibers and equipped with bar elements is arranged on at least two hose-like and made of flexible material and on the tree to be protected, which are to be separately attached. The arranged in the coarse mesh mat of natural fibers rod elements are advantageously made of bamboo, whereby a high mechanical stress is ensured.

The spacers are made of plastic and / or rubber and have at their respective two ends parts of a suitable quick-release connection. Thus, on the one hand, a force absorption under mechanical stress is ensured by impact effect, whereby the tree trunk and / or the root area are protected. On the other hand, the quick-release system allows quick assembly and disassembly.

The coarse-mesh prefabricated mat is preferably made of natural fibers such as coconut fibers, sisal, or seagrass. This makes it extremely tear-resistant and weather-resistant. At the end regions along the tree trunk or root axis, the mat has quick-connect elements, whereby a quick and uncomplicated installation can also take place here.

The rod elements are woven into the mat individually or as a bundle of at least two pieces per bundle and additionally fixed in the mat with fixing elements. This measure can be done on site or prefabricated. This offers the advantage that it can be individually adapted to the existing installation conditions and reacted to them without much effort.

With such a tree protection device for the tree trunk and the exposed root area can be optimally protected during a construction of the tree from damage caused by the construction or the required machine use, because of the specific situation of tree growth, the formation of uncovered root areas, and also on the possibly existing dangers of Tree protection can be turned off. The natural materials are to be dimensioned quickly to the required extent, they are made of renewable raw materials and both the natural materials and the quick-release systems are to be reused or replaced in case of wear.

The invention will be explained in more detail using an exemplary embodiment.

Embodiment:

For a road construction measure, it is necessary to protect the existing trees there, so that during the construction work no injury to the trees or parts of it can take place.

For this purpose, the solution according to the invention finds its use.

To the tree trunk, the exposed roots but also possibly endangered and to be preserved branch areas are first fixed to at least two different in the selected distance from one another arranged hose-like spacers made of rubber with the arranged at the end regions quick connectors. At least in the necessary protection area, a coarse-meshed mat of coconut fibers with fixing elements is arranged on these spacer elements and held together at the end regions along the root, root or branch axis by means of quick-connection elements. Bar elements, preferably made of bamboo material, are shortened if necessary to the desired or necessary length and threaded into the mesh of the coarse-meshed mat structure. In the area of roots or branches, these rod elements can be individually threaded and in the area of the tree trunk, these rod elements are threaded as a bundle of at least 2 to 3 rod elements, which were previously fixed together. In addition, these threaded rod elements are fastened in the mat structure with fixing elements, such as clamps, hooks and / or plastic quick-action elements.

In the area of the tree trunk, for reasons of saving time, it is also possible for a previously prepared mat weave of bamboo rod elements and coconut fibers to be wrapped around the coarse-mesh mat of bamboo fibers already arranged on the tree trunk and fixed along the trunk axis with quick-assembly elements.

In addition, this bamboo mat is attached to the coarse mesh mat with fixing elements.

Above all, this technical solution makes it possible to respond optimally to the special requirements of the areas of a tree to be protected in coordination with the possibly existing danger zones in order to arrange the best possible solution of the necessary protection of the tree areas quickly and easily and also after the need has ended to remove again. The materials used are interchangeable and reusable and consist for the most part of renewable raw materials. These natural materials are highly elastic, flexurally elastic and weather-resistant and thus offer a very good protection of the tree areas from mechanical stress caused by construction measures.
