Definitions

  • Scaffolding panels, planks or planks are currently made either from solid wood, from steel or from aluminum sheets and profiles, whereby attempts have been made to save weight for a number of years, instead of profiling the entire length and width of profiles 0 frames made of thin plywood panels, which are made weatherproof, insert, insert, insert, rivet, screw in, glue in, weld in or fasten in any other way.
  • the plates are available in various lengths of approx. 100, 150, 200, 250, 300 and more and widths of approx. 15, 30, 45, 60 and more cm, which are then lined up and arranged one behind the other in the individual heights, usually each display the scaffold at floor level, suspended in the scaffold construction.
  • different scaffolding panels are provided with access openings within the panel, which can be opened and closed if necessary.
  • 10 to 15 cm high side protection parts 5 made of the same material, preferably wood, and at a corresponding height railing and, if necessary, tarpaulin behind it are at the level of the scaffolding panels or nets attached to the sides of the scaffold structure facing away from the building, which then, taken as a whole, result in the finished scaffold.
  • the scaffolding panels regardless of the material, have one disadvantage in common: the craftsmen who have to deal with them every day describe them - especially with the lengths of approx. 250 or 300 cm, which are usual in the main 0 - too difficult to lay , The laying and hanging work is still to be done by hand, despite the possible transport of the plate stack with cranes and other aids.
  • the lightweight plastics often have the property of having too low a modulus of elasticity without reinforcement, so that the deflection of the plates, for safety reasons at least in Europe with a 1 / 100th of the length is only achieved by considerable thickness of the panels or by complex reinforcements.
  • the required low permissible deflection of the plates is due to the fact that with very often narrow plate widths, when lying side by side under load, there are stumbling points which lead to an increased risk of accidents.
  • composite panels and processes for their production from various materials which consist of a support core as a spacer for the upper and lower cover layers, are known.
  • the support core usually consists of foam, honeycomb,
  • thermosetting and thermoplastic cover layers with reinforcing fibers or fabrics are also known. Even heating elements between the different layers are used for the connection (WO 01/19937 A 1). This also applies to the connection with edge profiles that are placed on the composite panels, whereby the heating wires in strips made of hot glue or thermoplastic synthetic
  • Edge closures for composite panels made of thermoplastic are made using hot press tools by pressing and fusing the top and bottom cover layers and sealing
  • scaffolding boards are very heavy, difficult to transport and can only be assembled with considerable effort by man and machine.
  • the slightly lighter aluminum scaffolding panel is barely affordable and prone to theft.
  • Most scaffolding panels used to date are hazardous waste and expensive to dispose of after use.
  • the invention is therefore concerned with both the weight problem, as well as the problem of high costs and the development of a new manufacturing process which has the advantages of the easy deformability of the plastic as a whole, the light weight compared to wood, steel and aluminum and when using appropriate materials the combination of as many individual steps of production as possible.
  • the plastic scaffolding panel which weighs around a third of the weight of the wooden or steel plank board, is easy to transport and assemble, has already molded on the separately installed side protection if necessary and is permanently UV-resistant without further processing or impregnation and weatherproof and thanks to the structure embossed in the tread, it is non-slip and safe to walk on in any weather.
  • a directly molded side protection also contributes significantly to the improved static strength of the scaffold panel at no additional cost, further reduces the transport weight to the construction site and saves considerable additional assembly costs.
  • panels with a manhole are usually used, which generally have a much higher weight than the scaffolding panel, simply because of the frame and the hinges.
  • the frame and the hinge running over all or part of the length or width of the frame and the flap is made entirely of the same material by its compression, the plate in the usual plate thickness, the Frame by fusing the plate material and the cover layers to a statically corresponding rebate profile, unless a more cost-effective solution with a light metal, preferably aluminum frame attached to the edges of the plate or embedded in the plastic is not recommended due to the length of the plate.
  • O The hinge of the plate is permanently welded in or on by a thermal treatment of plate material with or without reinforcement in or on the cover layers of the flap and frame, so that this important access plate is lightweight and has the same height as the usual scaffolding plate and none selective increases as stumbling points.
  • the static values of this frame construction can then also be used for the overall dynamics of such scaffolding types.
  • the question of dewatering that arises here is solved by dewatering openings in the plate made by thermal deformation in the manufacturing process.
  • the panels can be colored permanently and weatherproof in any color.
  • Labels and company advertisements can be permanently applied or applied by fleece printing embedded in the plastic, by hot stamping in the manufacturing process or simply by subsequent printing using screen printing or pad printing.
  • Scaffolding panels, planks or boards are usually hung directly into the crossbeams of the scaffolding or, if they are less thick, inserted, inserted or riveted into attachable frames.
  • scaffolding plates or scaffolding plate frames have either screwed, attached or welded plates with claws or round grooves for hanging in upwardly open U-profiles and hanging on pipes, or plates with perforated cutouts for hanging in several on the Bolts welded or screwed on side by side.
  • Both the solid scaffolding panels made of wood and lighter panels made of perforated steel or aluminum have, based on the high material weight of the panel, a weight that is significant for scaffolding assembly even with half the usual scaffolding width of approx. 30 cm depending on the length - 5 Chen use of energy, especially for the assembly team, required.
  • the plate according to the invention no longer has this main disadvantage, namely the high weight of each individual plate, even in the case of double plate width, and can be used for any conventional scaffolding system with the specifically formed suspension devices.
  • a disadvantage here is that a different form of suspension is required for each system, which leads to a variety of production. 0 This last problem was solved in such a way that the plate can only be produced in one or two different plate thicknesses and mainly in double or triple scaffold plate width of approx.
  • customary two scaffolding plates with a width of approx. 30 cm can easily be combined with a length of 250 and 300 cm or more to form a plate of approx. 60 cm width, but also to much larger plates, and these with one Hanging device on the plate ends are pressed in one go.
  • thermoplastic reinforced edge closures and, if necessary, the insertion of an additional, also reinforced, web or with Large plate lengths of a round, square or rectangular tube or U-profile, also made of the same reinforced material or light metal, at the height of the support core in this or on the edge of the support core as an edge closure, all static requirements and in particular the requirements for the E Module covers.
  • damage to the scaffolding plate can be carried out in a simple manner with the soldering iron and thermoplastic repair material and, in the presence of a honeycomb 0 as the support core, no risk to the quality or durability of the plate is to be expected due to the limitation of damage to a few honeycomb tubes.
  • Another novelty in the reinforcement of the plastic top layers is the creation of a light sandwich panel top layer by laying on a perforated metal plate, which is either thermally connected on one or two sides with one or two thermoplastic layers or with a thermoplastic support core 5, so that either a perforated plate on one or two sides with a thermoplastic cover layer or a complete sandwich plate with one or both sides of perforated plate cover layers or a perforated plate encapsulating thermoplastic cover layers are created in a single hot and possibly cooling press pass.
  • thermoplastic connecting layers from the honeycomb as the support core to the perforated plate can be placed, rolled, sprinkled or sprayed on either in the form of thermoplastic films or plates placed between the support core and the perforated plate or in the case of closed support cores or spacers in powder form.
  • honeycomb material which already has an upper and lower full or partial hole cover during the manufacturing process, or else beads made of thermoplastic material at the edges of the holes, with the melting volume of which the perforated plate is then thermoplastic bonded to the honeycomb core.
  • honeycombs can be produced in the required honeycomb panel thicknesses in the direct extrusion process and can also be included in the production process.
  • the perforated metal cover layers can already have structures on the surface during their manufacture and can be provided on one or both sides with raised or recessed structures, eg. B. can also be provided with an anti-slip covering during pressing. Furthermore, a color design can also be achieved here by permanently coloring the thermoplastic material visible through the perforation, but also the perforated metal plate. This makes it possible, for example, for company products to be permanently labeled, which is just as good as theft protection as well as for advertising purposes.
  • the cutouts in the perforated metal plates can have different shapes, e.g. Round holes, oval or box-shaped perforations, oblong or square perforations, with and without rounded corners or a mixture thereof, crescent, cross or diamond shape, are arranged in straight or staggered rows, diagonally staggered rows or the like, with the relatively free perforated area being approximately the same Half of the plate, but can also make up more or less.
  • thermoplastic material is placed around the existing beads or tapered hole edges during hot melting during the melting process and thus the perforated metal plates connects the thermoplastic material in a non-displaceable, homogeneous, body-locking manner. 5
  • the connection of the thermoplastic material from the top cover layer to the cover layer below the perforated plate and via this or directly from the top layer is created via the hole cutouts when the hole edge is not formed.
  • the perforated metal plate has a tight fit due to the formation of the perforated edge or within the thermoplastic connection or cover material, it can be used for special demands the connection between the perforated plate and the thermoplastic can be optimized by a special treatment of the cover material, for example with a primer (adhesion promoter) or a roughening, other treatment already during the rolling process, so that even strong bending and impact stresses of the light scaffold plate are permanently absorbed can.
  • a primer adheresion promoter
  • a roughening other treatment already during the rolling process
  • the non-positive connection of the metal cover layer can be dispensed with when the light weight of the scaffolding plate is subsequently reduced, the direct connection of the primed metal layer or one with an adhesion promoter to the thermoplastic core is also appropriate. This also creates a weatherproof connection and when using structured sheets, the necessary slip resistance of the plates can also be achieved, which offers sufficient security with and without a structured plastic layer possibly additionally applied during the pressing process.
  • the aforementioned deformations of the plates are also possible here.
  • additives in the thermoplastic material of the cover layers, but also of the support core lead to properties that the base material does not necessarily have.
  • Additives such as short or long glass fibers, glass balls, talcum, more wood, wollastonite, zinc oxide, polyester fibers, metal powder, mica, calcium carbonate and the like lead to greater rigidity, a higher modulus of elasticity, 0 influence the flexural or creep modulus, the hardness , dimensional stability under heat, tear and tensile strength, compressive strength, dimensional stability, density, alternating bending strength, thermal conductivity and melt viscosity, decrease in elongation, impact strength, notched impact strength, tendency to creep, shrinkage, thermal expansion, abrasion resistance, UV and weather resistance - density, the melt index, etc.
  • the light scaffolding panels can be laterally or all around upwards, downwards or on one side upwards, on the other side downwards directly side parts by folding or edging or otherwise in any length, can also be formed with recesses, so that either the finished products are created during the hot pressing process or in a second shaping process.
  • the static absorption of the load-bearing capacities takes place mainly through the two cover layers connected to the support core and their reinforcement or the perforated metal sheets via the corresponding dimensioning of the height of the support core.
  • the already used frame plates with inserted or attached thinner floors or the wooden planks mainly by dimensioning the height of the metal frame or the planks.
  • the solution to the static problem of absorbing the load-bearing capacities in a thin scaffolding plate without using a frame can also, as shown according to the invention, by including the 10 to 15 cm high side part, which is prescribed for scaffolding anyway, as a supporting web on one side and one On the other side, bevelled or folded at a height of 5 to 10 cm without the thickness of the panel being unnecessarily expanded.
  • the covering and side or part thickness can also be kept very low, which also has an impact on the weight of the square meter.
  • the only problem is the stackability of the panels for storage as well as for transport, which was not only solved with the upward and downward folding of the side protection part and the supporting web, but also with the alternative possible upward folding on both sides. In both cases, only a slightly sloping stack is required to create vertical stacks; transverse storage is also possible without significantly greater surface loading, since there is no storage or transport area for the side parts.
  • the time saving during loading and in particular the scaffolding assembly must also be mentioned, which is not insignificant, so that the handling and assembly costs can be significantly reduced again.
  • This also achieves a considerable weight reduction. It weighs the scaffolding lightweight panel per running meter of scaffolding length with a panel thickness of up to 15 mm only including the side panel 3.5 kg, with a panel thickness of 20 mm only 4.2 kg, a reduction compared to previously customary scaffolding panels to a fraction of the weight. The same applies to other dimensions. Taking into account the omission of the additional side protection part to be transported or assembled, the weight reduction is much higher.
  • the lightweight scaffold panel or parts thereof then consist of colorless, translucent thermoplastic material.
  • the outer cover layer of the side protection part can be provided with an overlapping overlap to the nearest side, but also lower or upper panel, which resiliently and permanently on the other panel is set depressingly. This is permanently possible with a suitably aligned and hot-pressed glass fiber-reinforced material such as the plate with pre-tension.
  • the side protection parts and possibly attached side parts can also be provided with a permanent inscription in the thermoplastic layer, also for advertising purposes and for identification, whether by printing on a fleece or by attaching a hot-pressed structure or similar as already described.
  • thermoplastic plastic connection or cover layer to the thermoplastic support core.

  • sheet metal with a thin material thickness with beads or beads or other structures and to attach c-shaped, L-shaped or U-shaped webs to the two side parts, or to design these sheet-metal pockets and to lock them in these sheet metal sleeves.
  • the invention opens up a new type of scaffolding planking, securing and design in addition to saving weight-related transport costs, saving huge assembly and handling costs.
  • 15 gender film which can usually only be used a few times or even once, can be manufactured more stably and cost-effectively using reusable side cover plates.
  • the "lightweight scaffolding panel" with perforated metal cover layer according to the invention becomes a homogeneously bonded panel, in particular if a complete covering of the panel with perforated edge depressions, which are encompassed by the thermoplastic connecting layer, is dispensed with.
  • thermoplastic material of the cover or connecting layer engages behind the perforated plate in a number of places without closing the full surface of the cover plate capture, be attached and that in the form of round holes, square holes or elongated holes, hexagonal or polygonal holes, diamond holes
  • the individual recesses or perforations in the metal sheets can be made on the plate or on the band of steel, aluminum or other metal or thermosetting plastic provided for later division by punching, drilling, milling, sawing or other cutting, combinations thereof or other processes in all possible cell sizes are attached.
  • thermoplastic plate or foil material that has tightly arranged, endless glass fibers along the full length of the plate.
  • This material can also be used in several layers and, alternately laid lengthways and crossways, can have the same results as a fabric reinforcement.
  • a flexible closure or a partial deepening of the thermoplastic surface in the hole area on below the upper edge of the sheet for example to produce a structure for the slip resistance, the hot press and / or the cooling press or flat plate tool, which is passed through or passed through by both presses with the material to be pressed, with a heat-resistant, rubber-like, sealing and subsequently expanding, separable layer what causes the thermoplastic material of the connecting or covering layer to be pushed back towards the underside of the perforated plate at the perforated locations, so that the upper side of the perforated plate remains free of material. In addition to other effects, this also leads to material savings.
  • Another way of making the lightweight scaffolding panels from a single material, both for the cover layers and for the support cores and all the necessary fittings and auxiliary parts, is to use a homogeneous, polymeric monolith.
  • EP 0531473B1 refers to a process for producing a homogeneous polymeric monolith, in which a structure of oriented polymer fibers is kept at an elevated temperature, about 5-2 ° C. below the melting point, and some of the polymers are melted and then melted within one predetermined time window compressed or compressed and then cooled again to ambient temperature by standing in the air. These are melt-spun homo- or copolymer fibers, which then have a density of at least 90% of the original fiber density as a compressed product.
  • thermoplastic material consisting of the main thermoplastic material, which is modified in several layers with bidirectional molecular alignment. This brings considerable weight savings for the outer layers from highly oriented reinforcement elements of the same material with the same stiffness and strength as with glass fiber reinforcement.
  • Another new feature is the use of this material for the support core, i.e. for the manufacture of honeycombs, cones, boxes or bars.
  • this material for the support core, i.e. for the manufacture of honeycombs, cones, boxes or bars.
  • the distance between the individual spacer bodies from one another can be doubled or quadrupled without the load-bearing capacity of the plate being impaired.
  • this processed material whose structure has been changed, while maintaining the dimensions which are usually required, to reduce the material thickness and thus to make the lightweight panels even lighter.
  • the support components such as tubes (also connected to honeycombs), cones, webs or corrugated webs, boxes or the like, for example in the deep-drawing or hot-pressing process
  • considerable weight savings in material can be achieved while increasing the strength and, above all, it is then possible to the further processing of the material to form a complete lightweight panel while largely maintaining the necessary deep-drawing or hot-pressing o temperature, the cover layers of the same material then with the required pressure to thermally press on the support core, even without a nonwoven or adhesive intermediate layer, and to provide the pressing piece simultaneously or subsequently with the required structures, for example edge closures or a non-slip structure and fittings, made of the same material.
  • thermoplastic material that remains on the top or bottom of the tubes or cones, webs or corrugated webs, crates or the like in the deep-drawing or hot-pressing process of the same or considerably greater thickness than the material of the actual support body then serves at the same time to reinforce the cover layers and serves here at the same time in the case of linear longitudinal or transverse alignment to a further, substantial improvement in the rigidity and flexural strength and thus makes it possible to achieve an optimal, weight-favorable use of material, which is of course reflected in the price.
  • Another inventive consideration is to find a simple and inexpensive process technology which enables a coherent connection of the perforated metal plate with a thermoplastic and a statically effective base layer as a support core in a simple manner.
  • the support core which consists of either the known thermoplastic plastic honeycomb, tube, cap, box, web, corrugated web or similar structural panels or also plastic foam panels, is directly in one production step hot-pressed without an intermediate layer with one or two perforated sheets and cooled under pressure, so that the support core material deforms itself into the shapes of the perforated sheet required for the positive connection.
  • All properties that are expected from the later visible top layer e.g.
  • thermoplastic support core which also has a large positive influence on the strength and bending properties, and in particular the overall weight , 5
  • An additional, special property of the perforated metal sheet namely the existing countersinking or tapping of the holes and thus the possibility of a smooth surface of the cover layer, which is then made of metal and plastic, also provides the uniform, perfect coherent clawing and connection of the sheet Plastic material in the form of the variety of rivet heads safe.
  • the final thickness of the lightweight scaffold plate can be determined by the height of the support core before pressing. Inaccuracies and tolerances of the support core plates are compensated for by the specification of the final height, as are slight inaccuracies in the flatness of the perforated metal sheets or bones that arise during perforation.
  • the thickness of the connecting thermoplastic layer and thus the stiffness and flexural strength can be influenced.
  • both the hole sizes of the honeycomb, box or tubes, as well as the distance of the webs or cones etc. in the support core can be fully taken into account and a coherent, long-term stable connection can always be achieved.
  • the weight of the finished plate can be matched to the application, so that optimal results are achieved in the lightness of the plates.
  • the light scaffold plate also has other uses as a light plate. It is not only suitable as a scaffolding panel, but also as a floor and formwork panel and for a variety of other panels and load-bearing profiles that are subject to rigidity and bending strength. Such panels can be used as floor panels, shelf panels, insulation panels, soundproofing panels and panels for other areas of application which have to meet both static requirements and decorative purposes.
  • the plate can perform another important function using a gas-permeable support core and a gas-impermeable film fully encasing it as a vacuum panel. 5 Methods of manufacturing the plate are already discussed at various points in the description. However, the individual process steps are described again in detail in the following:
  • the .Light scaffolding plate made of a thermoplastic support core or other spacers that determine the color of the outside of the plate in overdimensioned thickness and the necessary width and length in the middle, above and below only a plate, a perforated plate or a countersunk perforated sheet is laid in a single hot pressing and cooling pressing process with temperatures for heating and cooling which are matched to the different melting points of the materials and the material thicknesses, in direct contact with the hot and / or subsequently hot plates of the press and / or the possibly To produce the required structure, it is necessary to place the perforated plate with the holes in the direction of the side facing away from the lower press plate on a structured separating film and to place the support core thereon in an oversized thickness.
  • the second perforated plate is then overlaid with the hole countersink in the direction of the support core and pressed with the structured separating film additionally placed in the direction of the plate and thermoplastic bonded to the panel previously determined in the later thickness and color.
  • the plate receives the final, sunken or raised surface structure and shape, as well as additional formings such as claws, grooves and other suspension fittings, closures, reinforcements, inlays and web inclusions, edges and perforations when using the appropriate molding tools.
  • the method using an additional thermoplastic cover layer between 5 perforated sheets and the support core is analogous, with the difference that the thickness of the support core approximates the final thickness of the plate with its cover layers and only the cover layers between the perforated or countersunk perforated sheet and the support core above and are inserted below.
  • the additional inscription of prepared lettering and motifs made of or on their color reflecting plastic film or fleece takes place directly above the o lower or below the upper perforated or countersunk perforated sheet layer before the pressing.
  • In order to press 'Lightweight Scaffolding Sheets' in several units at once in one press run with the stationary press these must be inserted next to or one after the other until the entire available press area is filled and at the same time hot pressed and cooled.
  • thermoplastic top layer During hot pressing, the thermoplastic top layer and / or the surface
  • An improvement in the stability, the modulus of elasticity and the UV and weather resistance of the plate is achieved by a greater strength and change in the material properties of the cover layer and / or the support core, and by an enlargement or reduction in the hole size and / or the lowering of the hole and / or influenced by staggered arrangement of the hole in the direction of the subsequent stress on the scaffolding plate.
  • honeycomb support core 15 upstream in the manufacture of the honeycomb support core, with or without a flattened plate surface or a continuous deep-drawing process for a support core in a tube, hat, box, web, corrugated web or similar structure.
  • the introduction of slits in the honeycomb structure can be further upstream.
  • this process can be done in a single, continuous process.
  • a "light scaffold panel" with a fiber-reinforced cover layer is produced in the same way, with only the fiber-reinforced thermoplastic cover layer being introduced instead of the normal thermoplastic cover layer and the perforated or countersunk perforated plate being dispensed with.
