Definitions

  • the invention relates to a plate made of stainless steel for draining wet masonry, which is driven into the masonry and is designed to increase its rigidity, the waves having their longitudinal axis in the driving direction.
  • the invention also relates to a rolling device for producing such plates.
  • the corrugation of the insulating plates increases their rigidity. In the known wave-shaped insulating plates, it can nevertheless happen that the plates inadvertently deform at certain points when they are driven into the masonry and jam in the mortar joint between the guides or against one another.
  • the boards can be made of harder and thicker material according to general knowledge. However, this considerably complicates the wave-like profiling of the plates.
  • the simplest way to produce such corrugated plates is by rolling or pressing, with them being deformed over their entire width simultaneously between profiled pressing tools or being passed through profile rollers in the longitudinal direction of the shafts.
  • this deformation is only possible when using plates made of relatively soft, easily deformable steel, because stretching of the material occurs here, which is due to the profiling process and is therefore unavoidable.
  • hard material that has a ferritic structure and is not stretchable cracks occur that make the boards unusable or at least cause disadvantageous deformations when driving the boards into the masonry.
  • DE-OS 25 05 199 describes a method for producing ventilation ducts.
  • Pipe linings and the like known, the so-called cross-profiling is used to produce corrugated channel walls.
  • Deformation rollers are used, which are arranged at a certain distance from each other and interlock with deformation ribs running in the axial direction.
  • a flat sheet metal sheet is passed through these toothed rollers, which is deformed into a corrugated profile with a trapezoidal profile cross section and then cut into the individual components with the aid of a cross cutting device.
  • This profiling process is basically also possible with hard material, because the sheet metal plates are only bent when they are deformed, but not stretched over the entire cross-section.
  • certain design features of the rolling device are required, and particular care must also be taken to ensure that the finished corrugated plates have a profile cross section which makes them suitable for their particular use.
  • the invention has for its object to improve the previously used for draining damp masonry stainless steel plates so that despite the use of hard material they have an advantageous profile for driving into the masonry and do not deform when driving, especially none cracks originating from the profiling, which are the moisture could endanger insulation.
  • Another object of the invention is to provide an improved rolling device with which the corrugated plates of hard material having the above-mentioned properties can be suitably manufactured.
  • the stainless steel plate according to the invention is characterized in that the cross-sectional profile of the waves is curved in its entire course and adjacent wave profiles merge into one another via turning points of the profile curves while avoiding flat patches, wherein they preferably consist of hard, non-stretchable material.
  • a plate profiled in this way does not have the greatest possible stiffness and is in particular less stiff than a comparable plate with a rectangular or trapezoidal wave profile.
  • the best possible local strength against denting in the area of the profile waves is achieved with sufficient buckling rigidity of the plate itself, so that the plate cannot be adversely deformed when driving into the masonry, even if obstacles encounter the shaft flanks.
  • the shape of the plate according to the invention therefore ensures not only a perfect driving into the masonry but also a time-effective, effective sealing of the masonry against rising damp.
  • a simple and therefore preferred embodiment of the invention provides that the wave profiles adjoining one another via turning points are circular or approximately circular. At the turning points, two circular sections with opposite curvatures adjoin each other, so that practically no flat surface pieces are present in the area of the turning points.
  • This wave profile can be produced with relatively simple rolling devices.
  • the rolling device according to the invention for the production of stainless steel plates for draining damp masonry which are driven into the masonry and are designed to increase their stiffness, the waves running with their longitudinal axis in the driving direction, has two deformation rollers which have a cross section have gear-shaped profile, which forms deformation ribs running in the axial direction, which mesh with one another in the manner of a gearwheel, the center distance of the two deformation rollers being greater than the sum of the radii of the pitch circles of the toothed rollers.
  • the interlocking deformation ribs are formed on their flanks as an involute profile, to which the profile of the tip circle and the base circle adjoins, the pressure angle of the deformation ribs in the region of the pitch circle being at least 30 ° and the tooth height of the deformation ribs being at least 15% of the radius of the pitch circle matters.
  • the inventive design of the deformation rollers ensures that only one deformation rib of one deformation roller is in engagement with a deformation rib of the other deformation roller, thereby stretching the mate rials over the entire deformation cross-section of the deformed plates and the resulting cracks can be avoided.
  • the possible diameter of the deformation rollers is limited.
  • the forming rollers which have to be long enough so that even long plates, for example with a length of one meter and more, can be profiled, therefore have a limited bending stiffness.
  • the deformation rollers held at their ends in bearings are provided with support rollers which act on the deformation rollers at diametrically opposite locations on the deformation rollers in the region between the bearings. It is then also possible to process relatively thick sheets without difficulty.
  • the support rollers expediently have a tooth profile with the same tip circles and root circles as the deformation rollers and are in engagement with them. It is a further advantage if the distance between the support rollers and the associated deformation rollers is adjustable. The appropriate contact pressure can then always be set depending on the thickness and rigidity of the processed sheet.
  • the distance between the deformation rollers, including any support rollers, can also be adjustable, for example by means of a wedge or vertical spindle bearing adjustment. This measure also serves to adapt the rolling device to the thickness of the sheets used and also to change the height of the corrugated profiles.
  • the support rollers are expediently provided in pairs, with a plurality of support roller pairs being arranged alongside one another along the deformation rollers and being adjustable separately from one another. This further increases and improves the possibility of adapting the rolling device to the respective operating conditions.
  • the deformation rollers for synchronizing their rotational movement are provided with gears which are rotatably mounted on them and which mesh with one another.
  • the deformation rollers themselves and their deformation ribs are thereby relieved of influences and forces which are required for synchronization, thereby precluding an adverse change in the wave profile of the plates due to such forces. It is advisable to provide the deformation rollers with their own drive motors with the interposition of elastic couplings.
  • a further advantageous embodiment of the rolling device according to the invention is that straightening rollers through which the plates are guided are arranged on the inlet side and / or on the outlet side of the forming rollers. These straightening rollers not only effect the correct feeding of the plates to be profiled into the rolling device, but in particular they ensure that the finished corrugated plates just leave the rolling device. This eliminates the need to straighten the plates afterwards.
  • the straightening rollers with rubber or plastic coated cylindrical rollers are advantageous. You can cross through the direction of the plates Deformation rollers can be arranged adjustable, whereby their position and their mutual distance can be adapted to the respective properties of the plates and the operating conditions. The straightening rollers are expediently adjusted empirically until the corrugated plates produced have a sufficiently precise plane shape.
  • a preferred embodiment of the rolling device according to the invention consists in that the deformation rollers are each rotatably mounted in a box-shaped housing, the housings are arranged one above the other in a frame so as to be adjustable relative to one another and have guide shafts provided one behind the other in the longitudinal direction of the deformation rollers, into which the support rollers are slidably inserted and in which they are supported by a set screw. It is a simple and robust rolling device, which nevertheless enables precise adjustment.
  • the straightening rollers are arranged on the box-shaped housings and are preferably supported with the aid of adjusting spindles, so that they can also be adjusted in a simple manner.

  • FIG. 2 shows the enlarged wavy profile
  • FIG. 3 shows a detail of a rolling device for producing the corrugated plate

  • FIG. 5 shows a side view the rolling device, partly in the axia len middle section
  • Fig. 6 shows a cross section through the rolling device along the line VI-VI in Fig. 5th
  • the plate 1 shown in Fig. 1 is made of stainless steel and is corrugated to increase its rigidity.
  • the waves denoted by 2 in FIG. 1 run parallel to one another.
  • the entire cross-sectional profile 3 of a plate 1 is composed of a plurality of wave profiles 4, which form wave crests and wave troughs next to one another.
  • the cross-sectional profile 3 is curved in its entire course, the adjacent wave profiles 4 only merging into one another via turning points 5 of the profile curve, avoiding flat surface pieces. 2, the wave profiles 4 are circular.
  • the straight line 6 drawn in dash-dotted lines passes through the apexes of a wave crest and the adjacent wave valley and through the intervening turning point 5, the curved course of the cross-sectional profile 3 being clearly visible. Deviations from the circular wave profile, which is also curved differently, are also possible within the scope of the invention can be. It is only essential that flat surfaces are avoided in the course of the cross-sectional profile, because flat areas would favor a local deformation of the plate.
  • the corrugated plates 1 must be made of hard, stainless steel so that they withstand the mechanical stresses acting on them and do not weather in the masonry itself.
  • the materials that meet these requirements can be difficult to deform, especially because they are not stretchable.
  • sheet metal panels made of such material are stretched, cracks and cracks occur, which, when the panels are driven into the masonry, impair the bending stiffness and the tightness can no longer be guaranteed after driving in.
  • the rolling device shown schematically in Fig. 3 enables the production of corrugated sheet metal plates made of hard material without this being stretched over the entire deformation cross section.
  • the 3 consists of two deformation rollers 7 and 8, which have a gear-shaped profile with deformation ribs 9 and 10 in cross section.
  • the two deformation rollers 7, 8 are arranged such that they can be rotated one above the other with parallel axes, their deformation ribs 9, 10 meshing like a gear.
  • the center distance of the two deformation rollers 7, 8 is greater than the sum of the radii of the rolling circles 11 and 12 of the toothing of the rollers 7, 8, shown in dash-dot lines in FIG. 3. This creates a space between the interlocking deformation ribs 9, 10 between them successively plates 1 are inserted to be provided with shafts 2.
  • the interlocking deformation ribs 9, 10 are formed on their flanks 13 and 14 with an involute profile, to which the profile of the tip circle 15 and the root circle 16 connects.
  • the deformation rollers 7, 8 are designed and arranged such that only one deformation rib 9 of the one deformation roller 7 engages with the deformation ribs 10 of the other deformation roller 8 stands.
  • the deformation rollers 7, 8 are designed with a relatively small diameter in comparison to the tooth height 17 of the two deformation rollers 7, 8.
  • the tooth height 17 is at least 15% of the radius of the pitch circle 11, 12 of the associated deformation roller 7.8.
  • the plate 1 is inserted in the still flat state in FIG. 3 from the left between the two deformation rollers 7, 8, which are driven at the same speed and in opposite directions.
  • the plate 1 is deformed and provided with the shafts 2 between the deformation ribs 9, 10 of the deformation rollers 7, 8.
  • the plate 1 can slide in the direction of its plane, so that only its width is reduced.
  • Fig. 4 shows schematically the entire rolling device with the shaping rollers 7, 8, the shaping ribs 9, 10 and with the sheet metal plate 1, which is provided with the shafts 2 as it passes through the device in the direction of the arrows.
  • the shaping rollers 7, 8 must, however, have a relatively small diameter in order to be able to deform the plates 1 without stretching.
  • the relatively thin deformation rollers 7, 8 can therefore bend, in particular in the case of greater lengths, which results in irregular wave heights over their length and the plates are given a convex shape.
  • FIG. 1 shows schematically the entire rolling device with the shaping rollers 7, 8, the shaping ribs 9, 10 and with the sheet metal plate 1, which is provided with the shafts 2 as it passes through the device in the direction of the arrows.
  • the two deformation rollers 7, 8 are therefore provided with support rollers 19 and 20, which each act on the deformation rollers 7, 8 at diametrically opposite locations on the deformation rollers.
  • the support rollers 19, 20 have the same gear profile as the deformation rollers 7, 8 and are in engagement with them, the toothings rolling directly onto one another.
  • the distance between the support rollers is 19, 20 adjustable to the associated deformation rollers 7,8.
  • the distance between the two shaping rollers 7 and 8 itself is expediently designed to be adjustable so that it can be adapted to the thickness of the plates 1 to be deformed and the height of the shafts 2 produced can also be selected.
  • the bearings of the deformation rollers 7, 8 can be provided with wedge or spindle bearing adjustments, not shown in the drawing.
  • the deformation rollers 7 and 8 are each supported in a box-shaped housing 21 and 22, the two housings 21, 22 being arranged one above the other in a frame 23.
  • the housings 21 and 22 have guide shafts 24 which are provided one behind the other above or below the deformation rollers 7, 8 in the longitudinal direction thereof and which are intended for receiving the support rollers 19, 20.
