The panels (1, 2) are moulded with identical grooves (3) having recesses (9) for connection by separate barbed jointing pieces (5). The barbs (8) run the length of the panel edges and can be symmetrically or asymmetrically arranged. The barbed joining pieces (5) are moulded in PVC. USE/ADVANTAGE - The walls, floors and roofs can be rapidly connected together to form self-supporting emergency shelters and the system allows prodn. of narrow width panels.

Description

The invention relates to the manufacture of walls and / or ceilings and / or floor, especially for emergency shelters.

Emergency shelters are urgently brought in crisis situations. Here It is important that the accommodations are made available quickly and can be assembled without great technical effort. I.e. the Emergency shelters must be easy to transport. It must at the same time take into account that only in crisis situations limited transportation options are available. Also the Economy must be taken into account. Aid measures are in Crisis situations primarily from charitable aid organizations ions. These aid organizations are unable to scale up sufficient scale to provide expensive emergency shelters.

Against this background is proposed after an older proposal to manufacture emergency shelters from plastic foam panels. Though there are production widths up to 2 m. However, widespread are German Lich smaller manufacturing widths.

The invention has for its object walls, ceilings and possibly floors to manufacture from plastic foam sheets of small width. After This is achieved with the help of a tongue and groove joint known per se reached. In contrast to conventional springs are fiction according to the springs, however, provided with barbs. The barbs are clear fen in the longitudinal direction of the springs. In the grooves are for barbs Recesses provided.

This system can be used to make the springs perpendicular to your longitudinal direction to press in the grooves or the plates transverse to the longitudinal direction to slide on the grooves. This results in a quick and easy manageable connection technology, which is also firm because the Plates not transverse to their longitudinal direction due to barbs  let move again. A particularly inexpensive system results if the plates at the connection points all in are grooved in the same way. Then the plates can be easily manufactured will. The springs are supplied separately or already on one Plate edge installed to prevent the springs from being lost.

The barbs are optionally arranged symmetrically or asymmetrically. The groove depths are for 30 mm to 100 mm thick plastic foam panels preferably 10 to 60 mm and the groove widths preferably 5 to 30 mm. The dimensions of the springs result from the groove dimensions. Here it is beneficial for the positioning of the springs if the springs toast in the deepest. Experience while inserting the springs the barbs deform because the barbs in the unloaded Condition protruding beyond the groove width. It is advantageous if the Barbs immediately when the spring is pushed into the groove Spread the recesses in the groove provided for the barbs can. This depends on the accuracy of the manufacturing. Preferably tolerances are therefore provided which are at most 0.2 mm. In Depending on the manufacturing tolerances are due to the spring plate edges to be connected more or less close to each other. At more precise manufacturing, the plate edges can close almost brought together.

A relatively large hook length is required for spreading the barbs advantageous. According to the invention this is achieved in that the Spring is reduced in thickness in the area of the barbs. There the spring is only subjected to tension, so that a relative small thickness is sufficient.

In contrast, the spring is to be connected in the area of the contact surfaces The ends of the plastic foam board also have other loads, in particular particularly exposed to shear stress. Therefore and for the sake of the tongue of the plastic plate edges fill in the groove this area (outside the barbs) completely.  

Surprisingly, it turns out that plastic foam panels Polystyrene or a similar plastic with closed cells self-supporting by the tongue and groove connection according to the invention Walls and ceilings for emergency accommodation can be put together. This applies to the usual lengths and widths of emergency shelters. About that In addition, the system according to the invention has the advantage of ver to be longer. I.e. it can make endless walls and ceilings the plastic plates are put together. In these cases stiffening provided after reaching certain lengths, the is preferably formed by plastic foam partitions.

Surprisingly, it also shows that verbun according to the invention which are made of plastic sheets of closed roof tiles, which none need additional sealing. Even if surface water gets into the Contact gap between two plastic plates penetrates, so the water caught and derived by the spring. With asymmetrical Feathers (with barbs arranged on one side) are moving towards it make sure that the barbs protrude upwards. That's how it is derived water penetration guaranteed.

The use of the system according to the invention is advantageous also possible where nodes arise, i.e. different joints converge. That is at the joints between the roof and walls the case. There the plastic foam panels of the roof are together set that the joints between the panels in sloping roof Run in the direction of the roof pitch. This is the drainage of the Water secured.

The connection between the roof lies in the joint area with the walls and wall-causing spring extending in the longitudinal direction of the walls below and directly on the inclined springs in the the roof forming plastic foam panels.

All grooves are preferably continuous in the plastic foam plates attached. This makes it possible to use the foam sheets to disassemble by moving in the longitudinal direction.

Various exemplary embodiments of the invention are shown in the drawing shown.

Fig. 1 shows the corresponding edges of two 40 mm thick polystyrene foam sheets. In the exemplary embodiment, the polystyrene foam sheets have a density of 40 kg / m 3 .

The polystyrene foam sheets 1 and 2 are grooved on the corresponding edges. The grooves are formed uniformly and are labeled 3 . In the exemplary embodiment, the grooves have a thickness of 10 mm and a depth of 40 mm. The grooves 3 are laterally provided with recesses 9 at regular intervals. The recesses 9 have a slot shape.

The grooves 3 cooperate with a spring 5 , which fills the groove 3 of each plastic foam plate over a length of 10 to 15 mm and then tapers to a thickness of 5 mm. The ver tapered part is designated 6 . On the tapered part, hooks 8 are attached. The barbs 8 are arranged in pairs. Two pairs of barbs 8 are provided for each groove 3 . The arrangement of the slot-shaped or groove-shaped recesses in the grooves 3 is selected so that the barbs 8 can have spread out into the recesses 9 in the situation shown. This position is also largely determined by the fact that the springs 5 are provided at each end with tips 7 , which ensure a clean positioning of the opposing hooks when pressed into the grooves 3 . The grooves 3 have been milled using end mills. Optionally, the milling process can also take place in several stages, with firstly a groove 3 being milled without the recesses 9 and then the recesses 9 being introduced using a form milling machine.

According to FIG. 2, a spring 20 is provided instead of the spring 5, which differs from the spring 5 by an asymmetrical form. The spring 20 has barbs on one side only, which are marked there with 22 be. Accordingly, the taper 21 is arranged on one side, so that the spring 20 with its central part and the tapering 21 has a T-shape.

The assembly of the springs according to the invention is shown in FIGS. 3 and 4 with a spring 30 which has only one pair of barbs 31 and 32 for each foam sheet 1 and 2 , respectively.

According to Fig. 1, the spring is first pushed laterally into the guts of a plastic plate. The tip of the spring 30 abuts the deepest part of the groove. This ensures that the barbs come into an exact position with respect to the recesses in the grooves.

After pressing the spring 30 into the edge of the plastic plate 1 , the edge of the second plastic plate 2 is pressed laterally onto the spring 30 and against the plastic plate 1 . The barbs spread into the recesses in the groove intended for this, so that the plates are held immovably by the spring 30 transversely to their longitudinal direction. In the embodiment of Fig. 3 and 4, the manufacturing accuracy is such that the plates 1 and 2 have mm by splaying of the barbs in the groove of the panel 2 only at a distance of 0.05.

Fig. 5 and 6 show a shelter, the slabs of polystyrene foam 41, 42, 43, 44 and is composed 45th A tongue and groove connection according to FIG. 1 is provided between all abutting polystyrene foam sheets.

The grooves are designed so that in the joint area 49 of the roof with the walls, the schematically illustrated springs 50 and 51 touch each other or the springs 50 from the roof-polystyrene foam plates 41 are over the spring 51 . The spring 51 is embedded in the upper end faces of the polystyrene foam sheets 42 and in the lower faces of the polystyrene foam sheets 41 .

The shelter of Fig. 5 has in the first region, a metal bar 46. In addition, metal rails 47 and 48 are provided at the foot of the end and side walls.

Instead of the selected plate material, another plate can also be used material come into question. For emergency shelters, the thickness of the Board material suitably between 30 and 100 mm. Especially favorable conditions result with a plate thickness of 40 mm.

For the plate material mentioned with thicknesses of 30 to 100 mm the grooves differ significantly in their dimensions. The groove depths can be 10 to 60 mm, the groove widths 5 to 30 mm. The invent In accordance with the invention, springs used consist of PVC. The material is medium hard. The hardness is 85 to 90 shore.
