Description

Description of the invention

An outer skin (2) made of aluminum sheet is attached to a welded square tube frame skeleton (1) using means not shown. Between the outer skin (2) and the insulation layer (3) made of hydrophobized rock wool, plastic air ducts (4) are inserted, which conduct outside air (5) and inside air (6). •A paneling (7) is attached to the insulation layer (3), which is attached to the square tube frame skeleton (1) using means not shown.

The paneling (7) is gas-permeable and has a conductive structure (8). Both are made of materials that do not emit any substances or mixtures of substances.

An insulating layer (9) made of hydrophobic rock wool is applied to the floor of the square tube frame skeleton (1) on a base plate (not shown), onto which floor elements (10) are mounted, which have a conductive coating (11). The floor elements (10) and the conductive coating (11) consist of a material that does not emit any substances or mixtures of substances.

The ceiling elements (12), which have an insulation layer (not shown), are attached to the square tube frame skeleton (1) and closed with a cover (13). The ceiling elements (12) are also made of a material that does not emit any substances or mixtures of substances.

The electrically conductive structure (8) and the electrically conductive coating (11) are connected to the square tube frame skeleton (1) and a central earthing point (not shown) for potential equalization.

State of the art

Room cells, especially containers, are well known for office workstations, workshop work, measuring purposes and medical use.

These, usually mobile, room cells consist of a steel skeleton, which is welded together from steel profiles, as the basic body.

The heat and sound insulation is achieved with polystyrene foam panels, glass or rock wool insulation panels, which are inserted between the inner paneling and the outer skin.

A vapor barrier in the form of gas-impermeable foil prevents water vapor from escaping from the interior and condensing in the insulation layer when it cools down. If condensation occurs, the insulating effect is reduced or eliminated and rot can form.

The interior of known room cells is hermetically insulated with a paint and wallpaper system so that no gas exchange can take place from the inside to the outside through the walls.

Gas exchange is only possible through open windows or doors. The windows can usually be opened in a locking mechanism that leaves a small gap.

A disadvantage of the known room cells is the fact that there is an increased energy requirement due to the windows being forced to be slightly open, possibly associated with drafts. Another disadvantage is that the well-being of the occupants is negatively affected due to the hermetic insulation of the interior and the fumes from the material and paint systems have a negative impact on health.

Another disadvantage of known room cells is that polystyrene panels are used for floor and roof insulation, which have relatively poor sound insulation, so that the impact sound is high.

The fire risk is high in the known room cells due to the use of Styrofoam, as Styrofoam is difficult to ignite and burns in the event of a fire. Small fires usually lead to the container burning down completely, posing a risk to the occupants, especially when used as living accommodation.

Another disadvantage of known room cells is that, due to the small amount of space available, electrostatic and/or electromagnetic fields can have a relatively strong effect through superposition effects ("electrosmog phenomenon"), which pose a potential risk to health. Equalizing the potential of the floor using conductive materials reduces this effect, but does not eliminate it.

Hermetically sealed walls of room cells for measuring purposes prevent the formation of strong fields, but cause a deterioration in the air exchange in the room and increase the negative effect on the state of health.

Aim of the invention

The aim of the invention is to eliminate the disadvantages of known room cells, i.e. to improve the health conditions in room cells, to reduce the fire load or fire risk, to reduce energy requirements and to improve sound insulation.
