Definitions

  • the invention relates to a stiffening rib according to the preamble of claim 1.
  • formwork panels such as those used for concrete formwork, are exposed to very high loads and must therefore be stiffened very effectively.
  • a formwork panel should be as light as possible so that it can be handled more easily.
  • Simple metal stiffening webs or ribs have proven unsatisfactory because of their high weight.
  • a generic stiffening rib is known from FR-A 2275605, the two side walls of foam ribs each having the sandwich structure which is decisive for the stiffening effect.
  • the third material is a perforated metal plate that is embedded in the plastic layer of the side walls. The reinforcement deliberately results only from the strength of the metal itself and to stiffen a plate-shaped element effectively, high stiffening ribs with a corresponding amount of metal are required.
  • the object of the invention is therefore to develop a generic stiffening rib in such a way that a higher stiffening effect is nevertheless achieved with a more compact overall height and thus lower weight.
  • the manufacturing process is as usual, that is, in a mold for the stiffening rib, the solid layer of the third material is positioned appropriately, and then the other two still liquid materials are poured into the mold on both sides.
  • the tensile pretension that occurs after cooling from the curing temperature has the effect that the stiffening effect does not start when the plate-shaped element begins to bend, but that loads are deflected without deflection up to the level of the pretension. Only loads that go beyond this begin to bend the plate-shaped element, the maximum deflection being less by a dimension corresponding to the prestressing for a given maximum load compared to a conventionally stiffened plate.
  • a plate-shaped element such as a formwork panel
  • a plate-shaped element such as a formwork panel
  • the requirement can be met with smaller stiffening webs, so that the plate-shaped element as a whole can be made more compact and lighter.
  • the features of claim 2 make production easier and the conditions are symmetrical, so that there is no delay.
  • 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 metal content and thus the weight content can be kept low and it is left to the other two materials to form the main volume.
  • the sheet metal strip remains straight and does not form a hump when cooling, which would completely or partially cancel the pretension. Due to the features of claim 8, a reinforcement of the plastic is achieved.
  • the features of claim 9 are particularly suitable when the stiffening rib is manufactured in a vacuum process.
  • the procedure is followed when printing processes such as e.g. in the SMC process.
  • the formwork panel together with the stiffening webs can be made in one piece.
  • the stiffening webs and the formwork panel form a composite, which leads to better stiffness and load options than the mere contact of the formwork panel with the stiffening webs since then, and due to the integrated spirit level, correct alignment at the construction site is made easier.
  • the Basis DSM 730 is a reactive resin compound sold by Thyssen Umformtechnik, the name of which has recently been changed to TC 730.
  • the metal strips interlock and they can run between the same room levels. It is therefore not necessary to increase the overall height because sheet metal strips cross each other.
  • 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.
  • circumferential webs 13 to 17 and the inner field webs 18 as well as the webs possibly 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 in relation 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. According to FIG. 2, a sheet metal strip 22 is inserted into it 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 does not lie 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 aT value of 14 x 10- 6 .
  • the sheet metal strip 22 has a higher aT 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 it is 5326.33 N / cm 2 .
  • This load would withstand, for example, glass fiber reinforced plastic SMC based on DSM 730. 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, the voltage diagram according to FIG. 9, ie the difference from FIG. 7 to FIG. 8, is obtained by superimposition, and by this difference the deflection has now become correspondingly smaller, ie, can be carried 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 transferred to the thermally quick 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 / cm2 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 everywhere, by no means rare materials. 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 an intersection by plugging one into the other.
  • a small excess 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 ° C.
  • the preload becomes even higher. The same is achieved if plastics are used which react and harden at even higher temperatures, because then the sheet metal strip 22 and possibly also 31 expands even more and is frozen in this even greater extent.
  • 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.
  • nuts 34 are cast in at the corner regions of the formwork panel 11. 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 heated in a different way, namely by connecting them in series.
