Abstract

The container, as a portable working space, has a flat structure element (S) as an inner or outer wall, floor or ceiling. It is composed of two cladding layers (1,2) with rib spacers (3), and an insulation material (4,5) between them in two layers of plastics or of rock- or glass-wool. The outer cladding layers and the spacers are of a plastics material, and the spacers take a metal profile (6) within their U-shaped sections. The plastics material contains fibers of glass, carbon, and the like, and can also include a grid for shrouding against electromagnetic radiation.

Description

The invention relates to a container, e.g. according to ISO standards and preferably can be used for mobile workspaces in civil and military use, according to Preamble of claim 1.

The growing importance of mobile, containerized systems (especially rescue stations, hospitals, command posts) with demanding Equipment forces the empty container weight in favor of the internals keep lowering. But this must not be at the expense of thermal insulation, the structural rigidity and a certain universality of the equipment respectively.

Generic containers according to the ISO standard have one, for example cuboid structure, e.g. according to DE 37 19 301 C2. Are next to it Container has become known, e.g. EP 0 682 156 B1 or DE G 92 16 314.9 U1, the next to a basic container, movable structural elements (flaps and / or Have extensions) for volume expansion.

DE 297 00 436 U1 discloses a large-volume container with a wall structure made of inner and outer layers, each made of plastic, and foam in between. The inner layer consists of a transparent plastic, which forms a vertical viewing strip that extends across the entire depth of the wall structure.

DE 92 00 602 U1 discloses a plastic lining for containers, tubs or the like. This is held together by means of metal profiles on the surface to be lined. There are spacers between the lining and the surface to be lined.

The stackability of the container is an essential dimensioning criterion, with expandable containers, the basic container makes the essential contribution to Stiffness delivers. The wall structure of commercial containers is by metallic Cover layers which are connected by metallic spacers, the gap between the two opposite Cover layers are filled with thermal insulation material (inserted or glued), see above that in addition to sufficient rigidity, good thermal insulation is achieved. An additional layer that reinforces the wall as well as another layer, even at intervals recessed metallic profiles, allow the attachment even heavier Equipment on the floor and on the vertical walls of the container interior.

The invention has for its object, while maintaining the aforementioned mechanical and thermal container properties to reduce the dead weight.

This object is achieved with the container according to claim 1. advantageous Embodiments of the invention are the subject of dependent claims.

According to the invention, the two cover layers of a container wall and the rib-shaped spacers made of plastic material, the spacers pick up a metal profile.

The ends of the rib-shaped spacers are fixed to the two cover layers connected and in particular serve to stiffen the structure. It results there is a wall structure made up of a plurality of directly adjacent chambers, their boundary surfaces through the spacers and the cover layers be formed. The chambers are filled with insulation material.

The rib-shaped spacers are advantageous in towards the container outside Form of a simple web (one-armed cross-section) built to the inside of the container merges into a two-armed cross section of the spacer. Between the two arms is the metal profile mentioned above, preferably with a positive fit, arranged.

In a preferred embodiment, the rib-shaped spacer faces the outside of the container towards a T-shaped cross-section on the inside of the container turns into a U-shaped cross section.

The cross-sectional shape of the spacers described results relatively long heat transfer paths between the inner and outer cover layer, so that overall thermal insulation is improved.

The metal profiles arranged in the spacers serve in particular for Load transfer for the equipment to be fastened to the inside of the container, e.g. Fitted wardrobes, instruments, etc.).

The two cover layers and / or the rib-shaped spacers can be in an advantageous embodiment made of a fiber-reinforced plastic material consist.

The construction principle according to the invention is particularly suitable for such Structural elements of the container that do not have extreme mechanical loads are exposed. It is therefore particularly suitable for extensions or flaps expandable container, but also not expandable for interior walls or floor walls Container.

With a specific weight of the plastics between 1 and 1.5 kg / dm ³ (13 to 20% of the specific weight of steel, 37 to 55% of aluminum), excellent strength properties can be achieved in particular by adding glass, carbon or Kevlar fibers , The heat conduction of plastics is approx. 1% of that of steel and stainless steel. Even if the material thicknesses of ribs and profiles, lying in the heat flow direction, have to be chosen larger than in the case of steel, there is a clear advantage with the consequence of reducing the negative influence of thermal bridges.

In a further advantageous embodiment, there is between the two cover layers an additional intermediate layer, also for the purpose of structural stiffening Plastic material, available.

The between adjacent spacers and the two cover layers formed chamber-shaped spaces can advantageously with vacuum insulation material, preferably in plate form, which is extremely low Has heat conduction. The application of the vacuum insulation technology known per se leads to a reduction in the weight and volume of the insulation material, a reduction in the wall thickness and an increase in the usable volume predetermined heat transfer coefficient. A granular or fibrous filler, if necessary together with getter material and IR opacifier, is from one multilayer composite film (metal film and e.g. polyethylene or polyester film) enclosed permeation-tight. With a system pressure of less than 5 mbar, the tight sealing of the foils and a negligible permeation rate becomes a with a thermal conductivity between 0.0035 W / (mK) and 0.0045 W / (mK) Lifespan reached more than 15 years. The size of the vacuum insulation panels, in the range of 10 to 30 mm thickness, can be adapted to the geometric requirements become. In contrast, the thermal conductivity values of conventional insulation material are e.g. Polyurethane foam or rock / glass wool, around 0.035 to 0.045 W / (mK).

The wall production by gluing extruded spacers and possibly the This is the intermediate layer and the insertion and / or gluing of the insulation material simplest manufacturing process. For series production, further developed automatable production processes possible. In the case of EMC requirements (EMC electromagnetic compatibility) can also use suitable grids as part of the Wall structure can be provided.

The butt joint of two panels according to the invention can be glued or riveted or screws, expediently reinforced by corner profiles on the outside and / or inside made of metal or plastic.

In addition to the use of the lightweight construction according to the invention, which in the most varied Wall thicknesses can be produced as a movable wall Structural elements in expandable containers, for walls with low loads, not expandable container as well as interior walls / room dividers of all kinds, this is suitable in small dimensions also as a base plate for laying in tents. Because in the event from hospital wards are safe accessibility, thermal insulation and easy cleaning required, properties that a tarpaulin laid on the floor does not have.

The construction of a container wall according to the invention leads to a reduction in Weight without the variability of the container in terms of interior (in particular attachment of equipment) is restricted.

Preliminary remark: In FIGS. 1 to 3 the upper side of the container wall is in the inside of the container is directed while the lower side of the container wall towards the outside, into the container environment.

Fig. 1 shows a section through a lightweight wall S according to the invention Container. You can see the two outer layers 1, 2 made of plastic and one rib-shaped spacer 3, also made of plastic, between the two Cover layers 1,2. The spacer 3 (hereinafter also referred to as the web profile), which is firmly connected at its ends to the cover layers 1, 2 serves especially to stiffen the structure. The spacer points in his bottom part has a T-shaped cross-section, and runs upwards with two arms, in Form a U from. This results in a chamber-like overall for the lightweight wall S. Structure of adjacent individual chambers, the chambers with Insulation material is filled.

In the upper, U-shaped part of the spacer 3 is a metal profile 6, which runs parallel to the cover layers 1,2. Since it is from top layer 1 and Spacer 3 is positively enclosed, it can be inserted without that an additional attachment, e.g. by gluing is necessary. The one from that Metal profile 6 enclosed space 7 is also useful with Insulation material filled. The metal profile is used in particular for load transfer Equipment to be attached to the container wall.

In the embodiment shown, the insulation material is in two layers 4, 5. there the outer insulation layer 5 is advantageously a vacuum insulation material. With the upper insulation layer 4 lying towards the inside of the container can also be a vacuum insulation material. But it is also possible the use of another, conventional insulation material, e.g. Mineral or Rock wool.

The thickness of the inner 1 and outer cover layer 2, as well as material thickness, more horizontally Distance and height (thickness of the wall) of the web profile 3 defines the wall rigidity firmly. The quality of the thermal insulation results from the choice of the insulation material (s) 4, 5 and their strength. The dimensions of the inserted metal profile 6 result from the load requirements, overall wall rigidity and absorption of equipment on the walls and floor.

The construction variant according to FIG. 2 has a comparison with the embodiment according to FIG. 1 an additional reinforcement layer 10 located in the interior of the wall Plastic, on. The inserted metal profile 11 emerges from the layer 1, namely such that it is part of the smooth surface facing the interior of the container the wall S forms. Layer 1 thus consists of several sections that are individually glued between the metal profiles 6.

Fig. 3 shows a variant of the metal profile in the form of a so-called. C-rail 12, which in Towards the inside of the container is open. Thus, by means of suitable Fasteners and loads without drilling work.

The glued joint 14 (Fig. 4) two at right angles to each other Walls 15, 16 with the structure according to the invention is formed by the internal L-profile 17 and the outer L-profile 18 reinforced. One corner of the room, i.e. the joint of three Walls, is either by fittings (case corner) or by three bevelled L-profiles completely covered.
