Sheet, mat or plate for structural engineering Purposes and apparatus for producing such a web, mat or plate.

The invention relates to a web, mat or plate for structural purposes, consisting of a carrier layer with attached to it, arranged at an acute angle to the carrier layer with mutual partial overlap Plastic tubes.

Sn is already known a building board in which the support schi chi aiah consists of a polyurethane plate. On their On the outside, plastic tubes are arranged in rows and attached by gluing. The arrangement of the plastic tubing is such that the free part of the same under is directed at an acute angle to the surface of the carrier layer. The protruding, obliquely directed parts of the Tubes are arranged with mutual partial overlap. Such building boards are intended primarily as a cover

for buildings, especially residential houses, restoration buildings and the like can be used. A roof covering made from such building panels gives the impression of a thatched house.

The well-known building boards in which the plastic tubes Are glued to a carrier layer made of polyurethane foam, have disadvantages in various respects, so that they could not yet be introduced in practice. A major disadvantage is that an industrial production of such Building boards is not possible. In addition, the connection between the plastic tubes and the carrier layer is through Inadequate bonding to withstand the strong weather conditions over long periods of time.

The invention has for its object to propose a novel web, mat or plate, which is also preferably to be used as a roof covering for buildings, but due to their structure a large-scale production Allowed with relatively simple technical means and, in addition, various installation and laying options guaranteed in practice.

The web, mat, plate or the like according to the invention is characterized in that the plastic tubes on a plastic film are attached as a carrier layer by thermal welding.

The essential idea of the invention is therefore not to use a rigid plate or the like as the carrier layer

take, but a plastic film, especially made of soft PVC, and on this the plastic tube through to attach thermal welding. The use of a plastic film as a carrier layer enables series production in the form of long webs, which are then cut to the required sizes for further use can be. Furthermore, the easily bendable plastic film as a carrier layer facilitates the Storage as well as when transporting the train, hat or the like, since the first made web, consisting of the Plastic film with the tubes attached, stored in the form of rolls or folded in some other way and can be transported.

When processing the trained according to the invention There are various possibilities for web, mat or the like. The web or Iiatte can be used without further processing be laid on a roof surface. But it is also possible, the web on individual plates, z. B. insulating panels or to conceal the like.

Further features of the invention relate to the construction and manufacture of the novel web, mat or the like.

The invention then solves a particular problem which arises when the components in question are laid. A Namely, such webs, Hatten, plates or the like on a larger area, for _o example, a roof surface, with directed perpendicular to the ridge or to the eaves joints laid, so the practice shows that

209828/0779

close connection of neighboring elements is not possible, but there are always visible spots. To this Difficulty mastering is proposed according to a feature of the invention, such panels, webs, hats or the like so that the two opposite side edges are at an angle to the direction the tubes run. The side edges are preferably arranged at an angle of 45 °. Up to these edges arranged plastic tubes protrude with some areas over these edges and thus result in the laying Several elements designed in this way overlap the joints so that they are no longer visible from the outside are.

In the following, further details of the invention are explained with reference to exemplary embodiments shown in the drawings, both of the web, mat or the like and of a device for producing such elements. It shows:

The ends of the plastic tubes 11 facing the plastic film 10 are fastened in a special way to the plastic film 10, namely by thermal welding, in particular by high-frequency welding. The high-frequency welding has the advantage that relatively high welding temperatures can be generated for a short time without holes or cavities in the parts connected to one another. In the invention, the procedure is such that the ends of the plastic tubes 11 are simultaneously pressed together during the connection with the plastic film 10, such that the compressed walls of the plastic tubes 11 lie against one another and are welded to one another and to the plastic film 10. This creates a particularly durable and permanent connection between the plastic tube 11 and the plastic film 10. By closing the ends of the plastic tubes 11 it is achieved at the same time that dirt, water or the like cannot penetrate the plastic tubes from this side.

The distance between the plastic tubes 11 from each other in a Row 12, 13 or 14 is chosen to be minimal, namely corresponds to the width of a flattened plastic tube 11, see above that the ends connected to the plastic film 10 are close together (Fig. 1). The plastic tubes go from row to row 11 arranged in a gap, so that overall a dense structure is formed.

When laying such sheets, mats or the like, the procedure is expediently that the mat, which is higher up on a roof surface with an edge strip Vj, has a corresponding plastic tube 11

covered free edge strips 16 of the underlying mat. The first row 13 facing this edge strip 16 is accordingly arranged at a distance corresponding to the width of the edge strip 16 from the edge of the hat. Ss is it is also provided that the lichweißwerk ^ ug can be pressed together the ends of the plastic tubes 11 and for welding with the plastic film 10 attached to this row 13 at a certain distance from the ends of the plastic tubes 11 is, so that the outermost ends 11a of these plastic tubes are not completely flattened, but one Form the starting edge for the lower edge of the next mat (see Fig. 1 and 2).

The flexible webs designed according to the invention, Mats or the like can be further processed in various ways, e.g. B. directly on existing roof surfaces from old buildings. There are also different approaches to building hay. The train bcw, had z. B. directly on a wooden cladding of the Roof to be glued, if necessary between the Wood cladding and the web, mat or the like according to the invention, a plastic film is introduced, which with suitable connecting means, e.g. B. cardboard nails, is connected to the wooden cladding. On the plastic film the sheet, mat or the like is then attached by gluing. It is also possible to use the invention BaIm, mat or the like to be applied to fabrics, e.g. B. on insulating plates made of foam plastic.

A problem generally encountered with such webs, mats or panels is discussed in FIG. This shows

209828/0779

ORIGINAL BATHROOM

a section of a roof surface with individual elements 17 and 18. These individual elements 17 and 18 can be both mat or Be track sections as well as prefabricated individual panels. The problem is that it is perpendicular to the ridge or eaves edge running butt joints between adjacent individual elements

17 and 18 remain recognizable in the laid roof area. This is due to the fact that the plastic tube 11 on the individual elements 17 and 18 run parallel to these butt joints and do not cover them sufficiently. Pig. shows a solution to this problem in that the lateral edges 19 and 20 of the individual elements 17 and 18, respectively, are at an angle to the plastic tube 11 are directed. In particular, run the edges at an angle of about 45 ° to the direction of the plastic tubes 11 and thus to the eaves or The upper and lower edges 21 and the inclined edges 19 and 20 result in the direction of the ridge by itself in the area of these edges 19 and 20 an overlap by the differently directed plastic tubes 11, since these partially between the adjacent individual elements 17 and

18 cover the resulting butt joints.

Such rhomboid-shaped individual elements are preferably used 17 and 18 made from a continuous web in which oblique severing cuts in accordance with the course of the Edges 19 and 20 are attached. This creates a triangular individual element 17 lying on the edge and on it subsequent rhomboid-shaped individual elements 18.

Figure 5 is concerned with the large-scale manufacture of webs in accordance with the invention. The plastic film 10 is withdrawn in sections from a supply roll 23.

On the top of the spread out plastic film 10, the individual plastic tubes 11 are through a suitable Device lying next to each other in rows and aligned on the bands to be welded. the Welding takes place with the help of elongated welding jaws 24, which have correspondingly designed welding jaws below the plastic film interact. The welding jaws 24 have a certain, limited length. To the partial coverage to ensure the plastic tubes 11 from row to row, the welding of the plastic tubes to the plastic film 10 is carried out offset from row to row. The lower row 25 in FIG. 4 is the most advanced. The row 26 above it, in which the free parts of the plastic tubes 11 partially cover the plastic tubes of row 25 by a length the welding jaws 24 back. Row 27 is set back from row 26 in the same way. This allows alΙο rows 24, 25, 26 .. by simultaneously performed Welding cycles extended by a corresponding section. The welding jaws 24 can be attached to a common, be arranged vertically movable! carrier (not shown) . The welding ^; is preferably carried out by high-frequency heating the parts to be welded. The welding backeri themselves are expediently heated up to about 100 °, So go that the parts to be welded cannot be destroyed.

The invention also enables the production of mats or Plo.tten to cover curved ".bauwerksteilen are known, for example, small structures such as pavilions, ^G-artenh.,: Suckers and the like, a kegeistumpfförmige

"or cone-shaped roof surface. For such building surfaces, mats 28 according to FIG .. with the plastic film 10 is in this case also with the aid of (arcuate or straight) seal jaws 30 of certain limited length. Conveniently, the device is adapted for making such mats 28 that one or optionally a plurality of Schweiflbacken 30 on a pivotable arm 31 are arranged, the welding jaws 30 being moved in sections along an arc in such a way that a circular or polygonal welding of the plastic tubes 11 takes place.

In Fig. 6 a special feature is also shown in this respect. Individual strip-shaped tracks of very limited width are layered one on top of the other and connected to one another in such a way that a thick or high component is created. This can be used to close the eaves for roof coverings and give the impression of a thatched house . For this purpose, strips 32 of the plastic film 10 in the width of the anchoring of the plastic tubes 11 are used on these films and placed on top of one another and connected to one another.
