Description

The present invention relates to a building material and a prefabricated construction based thereon.

There are many types and forms of building material in the prior art. It should be understood according to the invention under a building material not only consisting of a single material, but also composed of several materials and / or individual components or composable building material.

In particular, for the construction of easily to be transported to the site and as quickly as possible to install structures such as emergency shelter after earthquakes or the like, it is desirable that the building material has the lowest possible transport weight, good on or in transport vehicles or aircraft stowed and yet after the construction ensures a high stability and load capacity of the building material to be created construction. The construction should preferably have good thermal insulation properties. It should be possible with the help of such building material and constructions with large dimensions, such as large walls can be constructed.

To solve this structure, a building material is proposed according to the invention, which is formed of at least two, hollow webs or hollow chambers having plates or webs, each kinked at equal distances from each other mirror symmetry to form spaced honeycomb structures and surface superimposed on parallel, abutting connecting portions between the honeycomb structures are interconnected, wherein the surfaces of the joined plates or sheets are each connected to at least one base or cover plate.

Because, according to a preferred embodiment of the present invention, the junctions of the base plates, the junctions of the bonded plates or sheets provided thereon, and the junctions of the cover plates thereon may be staggered, the junctions are in contrast to other support systems known in the art , no vulnerabilities. In addition, a particularly high density of a construction constructed from the building material according to the invention construction is achieved by this arrangement.

A particularly easy to implement geometric design of the interconnected plates or webs results in the formation of hexagonal in cross-section honeycomb structures.

The load capacity of the honeycomb structures of the building material according to the invention can be improved if the honeycomb structures are filled with at least one filling material. As filling material a pressure-resistant material is then used as possible. The principle is similar to that of a reinforced concrete beam, which is also made from two separate materials. According to the invention, the honeycomb structures fulfill the function of a reinforcing steel for absorbing tensile stresses and the function of the filling material is similar to that of concrete, i. H. The filling material serves to absorb the pressure forces.

It is possible to fill the honeycomb structures only on a later pressure-loaded side of the building material. In this way, the weight of the building material according to the invention and the construction to be created therefrom can be kept low.

The honeycomb structures can be filled particularly quickly and easily using at least one foam which solidifies or solidifies after filling the honeycomb structures.

For this example, a 2-component foam, such as an amino foam or a polyurethane (PU) foam is suitable.

In principle, however, it is also possible to fill the honeycomb structures with sand, soil, snow, animal or mineral wool, straw, hay, wood, cork, foam glass, concrete, lightweight concrete, mortar and / or water.

Particularly lightweight and inexpensive construction material of the invention, if the plates or sheets of plastic, such as polypropylene or PVC, or cardboard are formed. If corrugated board is used to form the plates or webs, one obtains a very high strength with low weight and low price. When coating corrugated board or providing it with a waterproof skin, one also obtains a suitable material for the panels or webs of the building material according to the invention.

Advantageously, the connecting portions of the plates or sheets used to make the honeycomb structures of the building material of the invention are glued or welded together or mechanically connected together, such as by rivets or screws. In this way, the honeycomb structures can be easily prefabricated industrially, during transport of the building material to a collapse small volume and expand well during construction, z. B. to be able to fill the honeycomb structures well below.

The above object is further achieved by a prefabricated construction having exterior or side walls and at least one roof formed wholly or for the most part using an embodiment of the above-described building material according to the invention.

The prefabricated construction according to the invention may be, for example, but not limited to, an auxiliary shelter, a container, a silo, a bridge element and / or at least one self-supporting wall or wall panel.

In this case, the outer or side walls of the prefabricated construction in the form of a hexahedron or a circle or circular arc or more, be connected to each other by common walls connected hexahedron.

It is particularly advantageous if at least the outer walls of the hexahedron or the plurality of interconnected hexahedra of more than two, in the direction of the wall thickness of the outer walls behind one another plates or webs are formed with each formed between honeycomb structures, so that at least two honeycomb layers are arranged one behind the other, wherein the wall thickness of the outer walls is 10 to 25 cm, 50 cm or more. As a result, highly stable structures with very good insulation properties can be created in a short time. Typically, the buildings constructed in this way will have wall thicknesses between 15 and 25 cm. Wall thicknesses of 50 cm or more are useful if the walls have to provide protection against splinters or bullets or if the construction is to be heavily stressed statically, should not be filled and / or should have a large moment of inertia.

Preferably, at least one roof of the precast construction is in the form of a prism. The roof of the precast construction can also be a barrel, bow or mansard roof. The prismatic roof is of great advantage for the overall statics of precast construction and the most ideal construction. The joining of the triangles to a prism is however u. U. relatively expensive. The bearing surfaces at the top wall ends, for example, must be formed here obliquely, which u. U. difficult to realize. Then the alternatives mentioned above can be used.

Particularly stable and stable roof structures can be formed according to the invention if at least some honeycomb structures of the building material of the roof extending along a section of the at least one roof of the prefabricated construction are each provided with an elongated insert with a hexagonal cross section, which is filled with a filling material and its Ends are closed.

It has proved to be particularly favorable if the at least one roof of the precast construction is inclined so that rainwater flows into the honeycomb structures of the building material of at least one outer wall of the precast construction. Thus, the prefabricated construction according to the invention can also be used for collecting drinking or industrial water.

The water thus collected can be removed particularly well from at least one of the honeycomb structures, if in at least one of the honeycomb structures of the outer wall of a plastic insert is introduced and at least this honeycomb structure an openable and closable water removal device is provided. As a plastic is particularly suitable here polyethylene.

If water is collected in the honeycomb structures and this is to be used as drinking water, it is advisable to sterilize it as far as possible. The latter is possible if honeycomb structures of the building material are formed by the sun-facing outer walls and / or roof areas of the prefabricated construction of clear-plastic and can be closed at their ends. Due to the UV radiation of the sun, which should radiate over as many hours on the walls or the roof of the precast construction, an advantageous disinfection of the water collected therein can be made. The clear plastic can be, for example, polyethylene, polyethylene terephthalate or polycarbonate.

At the prefabricated construction according to the invention, a suitable toilet can be installed, which may for example be formed from the building material according to the invention and may be provided in the form of a hexahedron on an outer wall of the precast construction. In addition, it is useful to provide a dry-Fäkalienbehälter, which may also be provided in the form of a hexahedron on an outer wall of the precast construction and the side walls are formed of inventive construction material in which a collection and subsequent rotting of dry, for example, in a rotting paper bag in the toilet, trapped feces can be done. In the toilet, an activated carbon filter is preferably provided.

If photovoltaic elements are provided on the roof and / or on the outer walls of the precast construction, they can be used for energy production.

For producing warm or hot water, an embodiment of the invention is suitable in which dark tubes are laid in honeycomb structures of the roof and / or the outer walls of the precast construction, in which water is circulated and at least one water tank is provided on the prefabricated construction.

The water tank can be provided with sufficient tightness when the bottom and walls of the water tank are lined with a whole-part film.

To prevent this, can between the honeycomb of the honeycomb arrangement 10 nor a horizontal intermediate plate not shown here are introduced. However, it is also possible, for example, on the cover plate 14 a new honeycomb arrangement 10 apply and on this another cover plate 14 to install. The latter can be repeated as often as desired, whereby the rigidity of the arrangement can be further increased.

After the construction of the building material according to the invention 12 become the honeycomb structures 7 , preferably only at the place of use or installation, but advantageously not necessarily with a filling material, not shown here 25 filled. As filler 25 For example, a foam which solidifies or solidifies after filling the honeycomb structures, such as an amino foam or a PU foam, can be used. But it can also be any other, in the honeycomb structures 7 disposable, certain insulating properties and available on site material, such as sand, soil, animal or mineral wool, hay, straw, wood, cork, foam glass, concrete, lightweight concrete, mortar and / or water, as a filler 25 be used.

Pressed straw has almost the same thermal insulation as the highest quality insulating materials. If dried biomass is available on site, for example, it may be chopped into the honeycomb structures 7 be mashed. In the honeycomb structures 7 Made of plastic sheets or sheets, the biomass remains dry and is protected from rotting. Snow can alternatively be used as a good thermal insulation material as a filler 25 be used.
