Description

Plastic air bodies as a component for concrete construction liL is usually the Hood clay is piled up between two casings, so that a massive (heavy) Wall is created.

By using hollow bodies, considerable savings can be made Concrete, etc. can be achieved.

The previously used or known hollow bodies for building purposes consist of rigid, solid shells or shells, which are due to their construction and the rigidity of the material maintains its stability. Although hollow, these bodies are relatively heavy and not easy in large closed areas manufacturable. The handling of larger hollow body surfaces of this irt, as well as the production different surface shapes is relatively cumbersome and expensive.

The "bodies" proposed by me, on the other hand, consist of thin, elastic (easy and cheap to manufacture) plastic covers that are compressed with Are filled with air. The overpressure of the air in the plastic covers causes a deformation the plastic air body countered by the poured building concrete.

The overpressure due to compressed air in the plastic covers gives the plastic air bodies their stability and not the rigidity of the cover or shell, as is the case with the otherwise common hollow bodies for building purposes Don't fall around a cavity but around an "overpressure body". These elastic bodies should be arranged in large areas or strips, in rows, be summarized on top of each other.

These tracks can be used to create coherent areas according to the purpose separated or cut out.

Smaller plastic air bodies (e.g. with the volume of four bricks) allow the cutting out of complicated articulated or different designs adapted ,. Plastic air body surfaces. For this task, the (not against each other displaced) cuboid or cube shape, which can also be easily adapted to the coarser designs classify, be the most appropriate.

The square or cube shape is on the corners and edges (also due to production) slightly rounded to allow easier pouring of the concrete.

The cuboid shape enables a particularly large volume of air to be inserted into the components and easy cutting of the surfaces. Other shapes, e.g. spheres or similar bodies do not have these advantages. The low weight of the plastic air bodies enables easy handling.

The plastic material can be easily removed with scissors cut to size.

To make space for the insertion of pipes, beams, etc., can The bust is let out of the corresponding plastic air bodies (by pricking) If the air body panels are not to be separated, also when moving around of the plastic air body panels around sharply angled building grooves.

Openings of all sizes, e.g. windows, doors, etc. can be opened without difficulty be cut out of the plastic air body surfaces. The plastic air body surfaces Due to their elasticity, they can easily create a wide variety of form movements shapes are matched.

Due to the low weight of the plastic air body: he be much thinner and lighter than before.

In addition, the low weight of the components achieved in this way makes it possible the use of lighter beams, pillars, etc. and thus a considerable saving of building materials of all kinds and a reduction in energy consumption for those required Construction machinery.

Lightness, insensitivity and elasticity of the plastic air body tracts enable problem-free transport.

Of course, the plastic sleeves can also be used if necessary gas-filled is 1.

The plastic air bodies in the walls create an increased insulating capacity. Plastic air bodies of this type can easily be made in a variety of shapes so that they can also be used, for example, in ceilings, floors, pillars or stair steps (It is also possible to use suitable pipe and radiator shapes etc. use this method to install in walls, ceilings, floors @ etc.) Also kd £ inten the | @@ astikluftkorper have a favorable effect on the tensile strength of the building parts. in earthquake-prone zones.)

The production the plastic air body should be made in longer strips that are cut to size therefore shorter plastic air bodies (cuboids or cubes).

The structure of the wall will thereby more stable.

When a plastic air body track is full, a new plastic air body track is created put on and the embankment continued.

The plastic air body panels are mainly for surfaces such as walls, ceilings, Floors and roofs.

These types of plastic air bodies are fetly poured in and remain Part of the components.

Should, for technical reasons, the air body envelopes come out of the wall, or other components have to be removed, or several times to save money are used, they can also be used in tubular form. Air connection between the individual air bodies. In this case, the air body covers can also be made of rubberized plastic material.

These plastic or rubber hoses are filled with air between the Formwork inserted and poured with concrete. After that the next hose put on etc.

After the concrete dries, the air from the hoses will turn on let out one end so that the hoses are pulled out of the walls or components can be.

Examples of the most varied shapes of pull-out air hoses.

Thin plastic sheets and tubes can be used easily and inexpensively the most diverse and appropriate air body shapes are made with the most diverse breakthroughs to achieve useful structures within of the components.

This process can also be used in the manufacture of prefabricated components Find application.

The appropriately cut plastic air body panels, only held by light scaffolding, set up, and then with a finer one Concrete mass or other building materials, layer on layer, to be sprayed (spraying method). For this purpose, finely divided, Relief-like grids, or stronger expressions are pressed in, so that the sprayed on Concrete etc. can adhere better.
