Definitions

  • ABSTRACT A method for manufacturing load bearing structures, such as structural slabs or the like, from panels formed by tube sections extending parallel to each other and being connected together, each of which panels can be connected to at least one ply which may be provided with apertures, said ply covering completely or partially the front faces of all the tube sections lying in one plane.
  • One load bearing structure of this kind consists of a light-permeable, heatinsulating slab, in particular for structural or insulating purposes, which comprises two boundary sheets of a transparent or translucent material, e.g., a plastics material, forming therebetween a hollow space, and tube portions or small rods for the same or a similar material as the sheets.
  • a transparent or translucent material e.g., a plastics material
  • tube portions or small rods for the same or a similar material as the sheets.
  • the middle ply moulded bodies are arranged between two webs of paper and glued thereto. These moulded bodies consist of wood and either form hollow spaces by themselves or together with other moulded bodies. It is furthermore known to form middle plies for plywood boards from wood spirals closely pushed together, which are glued together at their contact points.
  • the invention thus has the object of providing load bearing structures of the type mentioned above, which are intended to be stable structures and which in spite of a finer internal structure, can be manufactured considerably cheaper than the above-mentioned load bearing structures (known per se), although extremely thin materials which have thickness of e.g., 5 microns and are therefore difficult to work and to manipulate, have to be used for the manufacture of the panels.
  • the tube sections serving to form the panels can be produced not only from extremely thin starting materials, for example from plastics, metals or light alloys but also form such materials which in the intermediate working stages have an extremely low tensile strength, as is the case, by way of example, with paper wetted by bonding material. It is advantageous briefly to interrupt the manufacturing processes and during this time to secure the tube lengthsformed in position when the separation into sections of the equal length takes place.
  • each tube length has proved to be particularly advantageous to produce each tube length by overlapping windings having the shape of helical seams. It thus becomes possible that each individual tube length receives a certain stiffness immediately after the winding, which is of great importance for the individual process steps.
  • a preferred feature of the method consists in that the winding of the tube lengths is carried out in at least one plane and the tube sections are removed layer-wise so as to form the block perpendicularly to the plane of motion of the tube lengths. Since the tube lengths are only wound in a single plane or in a single row, comparatively wide webs can be manufactured from a plurality of tube lengths, the separated part-lengths of which will then serve to form a compact block, whereby the cost of manufacture is considerably lowered. Separated part-lengths can also be so fed to the block so that one layer of tube length sections can be placed into the grooves of the uppermost, already deposited layer.
  • winding the substantially plane strips winding mandrels which extend parallel to each other in the direction of motion of the tubes to be manufactured and are spaced from each other.
  • a compressive force should be exerted on each wound strip, which does not only put the wound strip into rotation but also moves it in the direction of the mandrel axis relative to the mandrel. Winding will then take place without the necessity to drive the winding mandrels.
  • the winding mandrels can be arranged stationary or they can be freely rotatably mounted. it is particularly recommendable to exert such a compressive force on the wound tubes that each time a permanent shaping of a strip takes place.
  • tube length sections removed from the plane of movement of the tube lengths, which already are connected together and form part of the block can in order to be connected to newly produced tube lengths sections be moved back and forth transversely to the plane of movement of the end of the tube lengths and towards and away therefrom and thus be connected with the ends of the tube lengths produced, whereupon only then is a section of the tube length corresponding to the height of the block cut off.
  • tube length sections can also be cut from the tube length end areas in a length corresponding to the height of the block, and then be removed transversely from the plane of movement of the tube length, for combining them with those tube length sections which already form part of the block.
  • the mutual connection of the tube length sections which lie side by side in the block and also the stiffening of the individual tubes themselves are effected by bonding materials which are preferably applied as hardenable precursors to the tube material and subsequently hardened.
  • This additive can already be admixed to the substantially plane strips necessary for the formation of the tubes and/or to the tube lengths formed and/or to the tube length sections. This addition may be performed by spraying processes.
  • the invention also relates to apparatus for carrying out the method.
  • such an apparatus comprises several winding devices each provided with a mandrel, to which winding devices at least one strip of material can be fed; these winding devices are arranged extending parallel to one another in at least one plane, the strips of material surrounding the mandrels being subject to the influence of one or more pressure means rotating and advancing the strips about the mandrel axes.
  • separating means for cutting finished tube lengths into equal lengths as well as means which move tube length groups having equal lengths transversely to the plane of finishing and combine them into a block.
  • the pressure means can thus consist of at least one rail which is movably guided to and fro transversely and longitudinally to the direction of motion of the tube lengths and can only be brought into work in connection with the tube lengths during one of the to and fro movements. Guiding this rail involves no difficulties nor do disadvantages occur during the return movement of the rail since this return movement can be carried out relatively quickly. it is, however, more expedient to provide on the circumference of a cylinder extending transversely to the axes of the tube lengths, several rails guided parallel to the axis of rotation of the cylinder, which are controlledly movable to and fro.
  • a roller arranged transversely to the axes of the tube lengths, which can be driven about its axis, and is guided so as to be movable to and fro in the direction of its axis and can only be brought into working connection with the tube lengths during one of the two to and fro movements.
  • each individual tube length a pressure means consisting of a drivable wheel, a roll or the like, the plane of rotation of which extends in the direction of the pitch of the windings. Since the individual tube lengths have in any event a certain distance from each other, the mounting of such wheels, rolls or the like does not cause any difficulties.
  • each roller or each wheel should be provided on its face coming into working connection with the tube lengths, with a deformable coat, and that each mandrel should consist of a material having as low a frictional resistance as possible, as is the case with polytetrafluorethylene (trade name Teflon).
  • each pressure means is arranged at a spacing of at least two winding pitches from the input point of a strip
  • each strip being fed in can be put under tension by a braking means.
  • each winding mandrel is designed as a hollow mandrel and to provide therein a duct for conveying a bonding material to the inner surface of the tube length. It is furthermore possible to assign supply means to the tube lengths or tube length sections for the application of a bonding material to the outer surfaces of the tubes or tube sections.
  • a panel designed according to the invention consists of parts arranged in layers of preferably wound, layer-wise formed tube length sections which are mutually connected by means of bonding material, the layer preferably constituting parallel panes.
  • foils of cellulose derivatives thermoplastics (such as polymethacrylate), thermosetting resins (such as epoxy resin), rubber (or other elastomers), organic fluorine containing polymers (such as Teflon, polyvinyl fluoride), molecularly oriented high polymers, such as two-dimensionally stretched polyamides or polyesters,
  • Metal foils which are preferably electro-deposited but can also be e.g., rolled, in particular hard-rolled aluminum foils.
  • thermosetting foil can be provided with glass fibre cuttings.
  • the webs serving to produce tubes consist e.g., of strips which contain incombustible fibres, or of hardrolled light alloy strips or of foil strips produced by electro-deposited or of thin metal strips.
  • the incombustible fibres may consist of asbestos or melted silicates, to which preferably cement is added as an incombustible binder; also gypsum may be added. If for special purposes of use hard-rolled light metal foil strips are employed which are particularly recommendable, it is preferred to connect the wound tubes or tube sections together by means of thermosetting resins although also other bonding materials may be used.
  • the webs can also consist of electro-deposit foil strips, e.g., hard nickel, or of thin metal strips, for example chromium nickel steel, in which case a solder can be used as a bonding material. It is also possible to wind thin metal strips which after their production are welded together by the action of heat, should preferably be carried out in an atmosphere of protective gas. Incombustible bonding materials can be added prior to winding or else only after the winding.

Of a plurality of strips or tubes, also here only four of them are shown. It is assumed that the starting material consists of a web 18 which is cut up into individual strips by a cutting device formed by severing discs 19. These strips are fed via pairs of conveyor rollers 20 to the winding devices which are arranged in the area 7. In order to put the wound tubes into rotation on the one hand, and to move them in the feed direction on the other hand, pairs of guide rails 21, 22 are provided in the case of the embodiment of FIGS. 5 and 6, which are controlledly moved to and fro, transversely and longitudinally of the direction of movement of the tubes.

If necessary additional pairs of guide rails 26 or the like can be provided at a short distance in front of a cutting-off device 25.
  • FIG. 1 according to which tube sections 11 are cut off the tube lengths before being combined to form the block 5, it is here assumed that separation only takes place when the ends of the tube lengths have been pushed onto parts of the block to be produced and have been connected therewith.
  • a ram 28 moving to and fro in the directions of the double arrow 27 helps in the stacking of the tube sections, roller 29 being provided to guide the already produced part of the block 5. How the connection is effected is immaterial per se; for connecting tube sections to the block 5, the block can be moved vocational stepwise.
  • a block 5 After a block 5 has been completed, it can be split up into panels 30; when for example synthetic strips or unwoven web of synthetic fibers mutually secured in position by thermoplastic binders, were used as starting material, instead of cutting means, such as saw blades, also electrically heated wires 31 may be employed.
  • bonding materials applied can be activated by heat sources, such as lamps 24a.
  • FIG. 7 shows an embodiment of a winding method.
  • a winding device which consists of a mandrel 32 which is mounted in a bearing 33 and is of such length that it serves as a support for pressure means, here a pair of rails 21. 22.
  • the mandrel is moved in the direction of the direction of the double arrow 34, synchronously with the winding movement, said mandrel can also be arranged only for rotation.
  • a cylinder 35 is provided on its circumference with several rails 37 controlledly movable to and fro which are guided parallel to the axis of rotation 36 of the cylinder.
  • the cylinder 35 rotates about an axis extending transversely to the direction of motion of the tube.
  • the rail which at that moment exerts a compressive force on the wound tubes, is additionally displaced transversly to the direction of motion of the individual tubes so that the resultant action is in the direction of the pitch of the winding.
  • This control is effected by slide earns 38 which are in engagement with the front faces of the individual rails.
  • the individual tubes are supported by a roller 39 mounted in parallel to the cylinder 36; instead of said roller 39 also other support means may be provided.
  • the mandrels 32 are also here freely rotatably mounted in bearings 33. Obviously a plurality of mandrels is provided for producing a plurality of tubes although only two winding devices have here been shown.
  • FIG. 10 and 11 shows that in place of a cylinder provided with rails, also a roller 40 may be provided which can be put in rotation about its axis 42 in the direction of arrow 41 and is also guided movably to and fro in the direction of the axis 42; this is indicated by the arrow 43.
  • This feature is particularly advantageous when the winding processes have to be interrupted for a short time for the severance of tube sections since the roller 40 can then be returned to its initial position during this short interruption.
  • the mandrels 32 are fixedly mounted at 44; the mandrels have a coat of polytetrafluorethylene (trade name Teflon): they can also be rotatably mounted.
  • FIGS 12 and 13 shows a further possibility of how the individual tube windings can be acted upon in the sense of rotation and feed.
  • pressure means drivable wheels, rolls or the like 45 are provided, the axes of rotation of which are designated as 46.
  • the wheels or the like 45 extend obliquely to the direction of motion of the individual tube windings.
  • mandrels 32 are fixedly mounted at 44 and they are of hollow construction for receiving ducts 47 which serve to feed bonding material or the like to the inner wall surfaces of the individual tube windings.
  • the compressive force exerted by the rails, roller or wheels should preferably not only be so great that each tube winding is rotated and advanced thereby; the compressive force should also enable a permanent deformation by a certain amount in each wound strip as shown in FIG. 14, as a result of which the rigidity of each individual tube length is considerably increased.
  • each pressure means which comes into working contact with one or more tubes, with a deformable coating, for example of rubber so that the compressive force exerted by each one can be distributed over the surface on which it acts.
  • the substantially plane strips can also consist of most dissimilar materials and they can also be wound into tubes using different means.
  • bonding materials for the reciprocal location of the individual windings and for connection tube sections to other sections also differently composed bonding materials may be used, for example glue, lacquer, silicon rubber, hardened casting resin (thermosetting plastics), cement, gypsum, metal or the like.
  • glue, lacquer, silicon rubber, hardened casting resin (thermosetting plastics), cement, gypsum, metal or the like Similar considerations also apply to other connection means; tube sections can be connected to other such sections also by soldering, welding, sintering or the like, depending on the starting materials used.
  • the blocks produced and the load bearing structures manufactured therefrom have a relatively low specific weight since the wall thicknesses of the starting materials used can be extremely small; these thicknesses vary in magnitude between a few microns and 0.1mm (100 microns). Since no difficulties are caused by arranging winding devices closely side by side, a plurality of tubes, for example one thousand side by side, can be produced simultaneously in a single plane. It becomes thus possible to produce panels, the width of which corresponds to the height of a room, whilst its length has to be suited to requirements.
  • incombustible fibres which are provided with incombustible bonding materials, for example fibres of fused silicates, such as a glass or slag, to which cement or gypsum-containing bonding materials are added before or during the manufacturing process of the blocks or panels, it will be possible to manufacture non-combustible building elements of high heat insulation which are not only relatively light in weight and stable but which can not even be deformed by an excessive action of heat.
