Definitions

  • the invention relates to a device according to the preamble of the main claim.
  • formwork panels are reusable and serve to support the concrete as long as it has not yet set. They are used for the production of walls. In this case, two mostly parallel formwork panels limit the thickness of the later wall.
  • Such formwork panels are also used for slab formwork, the protection of beams, the formwork of pillars, etc. In operation, they have to meet numerous requirements that are very contradictory. For example, they have to be light. This is because as single formwork panels they have to handle one man or two men if possible. But even if the formwork panels are to be lifted with a crane, they should be light, because in this case several formwork panels are connected to each other.
  • the formwork panels normally used are heavy, because the formwork panel consists of a thick sandwich panel with the main component wood. The frame and the formwork panel support the rear
  • the object of the invention is to provide components of the type mentioned, which is considerably lighter than the lightest metal formwork, which is easy to manufacture and which, despite the low weight, is both able to withstand the rough treatment customary on the construction site over the long term and also Above all, is able to absorb the hydrostatic pressures that occur during concreting. It should be possible to demold better than was the case with aluminum formwork bi slang and it should also be achieved that the surface quality of the formwork panel is and remains excellent.
  • Such a device can also be used as a plate for winter construction, it can be used as a roof for barracks, etc.
  • the component can be preloaded.
  • the two outer materials would be overused.
  • the load that the plastic has to withstand is reduced. If the curing temperature is significantly above the operating temperature, which z. B. at 130 to 150 ° C, then the state of the bias is frozen in such high temperature ranges that they can never be reached in operation.
  • the features of claim 3 can be used to protect the third material, and furthermore only one layer of the third material is required.
  • the third material then offers its entire surface to the first and the second material.
  • the features of claim 5 ensure that the third material offers a very large area compared to the second and first material, because such sheet metal strips are largely two-dimensional. The prestressing forces can therefore be absorbed over a large area.
  • the sheet metal strip remains straight and does not form a hump when cooling, which would completely or partially remove the pretension.
  • the features of claim 9 are suitable for such processes if the device is manufactured in a vacuum process.
  • the procedure is followed if one uses printing methods such. B. wants to manufacture the SMC process.
  • the features of claim 12 make the device more predictable, it is easier to achieve symmetrical relationships, with bends in this zone the third material is used less or not at all and no one is required special surface treatment of the third material, such as roughening or the like.
  • the features of claim 14 mean that the end of the third material does not have to absorb any specifically high forces, so that the risk that no cracks may result from this sharp-edged end is minimized.
  • the formwork panel together with the stiffening webs can be made one piece.
  • the stiffening webs and the formwork panel form a composite that leads to better stiffness overall and leads to higher load options than the mere contact of the formwork panel with the stiffening webs since then.
  • the frame since then can be omitted and this area can also be made in one piece with the formwork panel.
  • the invention is also applied to the inside jetties. However, it is not necessary to stick to the grid of parallel bars since then. Rather, the inner webs can now also form triangular shapes, hexagonal honeycomb shapes or the like.
  • the first and second material can also interlock, so that the sandwich has a better bond.
  • the invention is particularly suitable for applications according to claims 26 and 27.
  • the metal strips interlock and they can run between the same room levels. It is therefore not necessary to make the components higher because sheet metal strips must run in them.
  • a formwork panel 11 has a formwork plate 12, four circumferential webs 13, 14, 16, 17 and, parallel to the circumferential webs 14, 16, a larger number of inner field webs 18 which are approximately 22 cm apart. According to the dashed lines 19, further webs of the shape of the inner field webs 18 can also be provided at a uniform distance and parallel to the circumferential webs 16, 13.
  • the circumferential webs 13 to 17 have a width of 2.3 cm and are therefore considerably narrower than the circumferential webs which have been made of steel or aluminum since then.
  • the inner field webs 18 have a width of 6 mm, which is also considerably less than the inner field webs that had been since then.
  • the circumferential webs 13 to 17 and the inner field webs 18 and any webs that may be present according to the dashed lines 19 are conical to a small extent from the plane of the drawing in FIG. 1, with the exception of the circumferential surfaces 21 of the circumferential webs 13, 14, 16, 17, which Circumferential surfaces 21 are perpendicular to the plane of the drawing in FIG. 1.
  • Such a formwork panel 11 weighs approximately. 30 to 32 kg, which means considerable savings compared to an aluminum formwork of 39 kg or even a steel frame formwork of 68 kg.
  • the inner field bridges 18 are 96 mm high. 2, a sheet metal strip 22 is provided in the center plane or meandering around it. Its lower end 23, as shown in FIG. 2, is at a small distance from the end face 24 of the associated inner field web 18.
  • the upper end 26 projects into the formwork panel 12 to such an extent that it is essentially in the neutral zone of the formwork panel 12. Because the Formwork panel 12 is still connected to the circumferential webs 13 to 17 and the inner field webs 18, the neutral zone of the formwork panel 12 is not approximately in the middle thereof, but is further shifted downward according to FIG. 2.
  • the formwork panel 12 has on its upper surface 27 according to FIG. 2 a roughness which is negligible in this trade.
  • the sheet metal strip 22 is 1 mm thick and consists of steel of the type St 37. It is corrugated like corrugated sheet with corrugations 28 in its longitudinal direction.
  • the material of the formwork panel 12 and the inner field web 18, with the exception of the sheet metal strip 22, is made of glass fiber reinforced thermosetting plastic with an ⁇ T value of 14 x10 -6 .
  • the sheet metal strip 22 has a higher ⁇ T value of 21 x 10 -6 .
  • FIG. 7 shows the voltage diagram for the inner field bridge 18 in the zero state with the payload applied.
  • the minus sign means pushing force and the plus sign means pulling force. Where the two fields meet is the neutral zone. In the example, 5326.33 N / cm 2 .
  • This load was e.g. B. Endure glass fiber reinforced plastic SMC based on DSM 730. However, the deflection of the inner field web 18 would then be much too large, ie the surface 27 would bulge.
  • the sheet metal strip 22 now exerts an exactly opposite prestress of 4174 N / cm 2 . If one now looks at the entire inner field web 18 (in the diction of the main claim "component") then one obtains the voltage diagram according to FIG. 9, ie the difference from FIG. 7 to FIG. 8, by superimposition, and the deflection is now correspondingly smaller by this difference become ie portable in practice.
  • the pretension is generated by shaping the glass fiber reinforced plastic and the sheet metal strips 22.
  • the glass fiber reinforced plastic now reacts chemically, and since this process is exothermic, heat is generated in the range of 130 ° C. This heat is also transmitted to the thermally agile sheet metal strip 22, which now expands relative to the materials surrounding it. At this temperature of 130 ° C., the thermosetting material now hardens and connects to the sheet metal strip 22. Although the whole thing cools down, the sheet metal strip 22 remains connected to the material and now contracts relative to the hardened plastic. This results in the pretension according to FIG. 8 of 4174 N / cm 2 in the area of the highest pressure or the highest tension.
  • the plastics have no cold creep properties. These would also be prevented by using fibers.
  • the plastic used can be nailed with steel nails. It is water-repellent and does not take on concrete.
  • the materials are freely available on the market. For example, the companies Bayer and Hoechst offer the material DSM 730.
  • the glass fiber reinforced plastic SMC can be prepared by yourself or can be bought ready-made, so that you only have to move it with an activator before entering it into the mold. Plastic and glass fibers are available materials that are by no means rare. If necessary, they could be patched in the manner of mending boat hulls, gliders or the like.
  • the sheet metal strip has holes 29 through which the plastic material can connect, so that a positive connection also takes place and the plastic not only adheres to the surface of the sheet metal strip 22.
  • FIG. 4 shows how the sheet metal strip 22 can be formed when it crosses another sheet metal strip 31.
  • a notch 32 is then provided in the sheet metal strip 22, which extends a little more than up to half of the sheet metal strip 22 and is wider than the sheet metal strip 31 is thick.
  • a notch 33 is made in the sheet metal strip 31, so that the sheet metal strips 22, 31 can form a crossing point by being inserted into one another.
  • a small oversize in the notches 32, 33 is sufficient for the sheet metal strips 22, 31 to be able to stretch easily at the temperature of 130.degree.
  • sheet metal material is also provided in the formwork sheet 12, which is either inserted as a strip or better inserted as a sheet metal plate, which, however, is not full-surface, but has holes according to the holes 29 from FIG. 3.
  • screws 34 are cast in at the corner areas of the formwork panel. A screw can be screwed into this in the viewing direction of FIG. 1. Furthermore, in each of the fields visible in FIG. 1, a level 36 and a level 37 perpendicular to it can be formed, so that one can see later whether the formwork panel 11 is also perpendicular.
  • the sheet metal strips must be electrically connected to one another at the crossing points or the bluntly adjacent points, which can be easily achieved by wires serving only for the electrical connection.
  • Fig. 6 shows that the sheet metal strips can also be done in a different way, namely by rear interconnection can heat up.
  • the device according to the invention has a significantly longer service life than all known devices.
  • the number of uses of the device according to the invention is also significantly higher than that of known devices. Since the material that comes into contact with the concrete is dead plastic material, this material is insensitive to concrete. With rough treatment on site, the device is much less sensitive to damage. For example, dents remain around steel, and particularly on aluminum, when a stack of devices falls apart, is hit on it, or the like.
  • the device according to the invention absorbs such forces resiliently and returns to the starting position. If cracks do occur, they can be repaired by laypersons just as easily as cracks in leisure objects can be repaired by laypersons.
