Definitions

  • the invention relates to a support in construction and a method for producing a pipe of a support in construction.
  • supports that are usually height adjustable, for example, used to build slab formwork.
  • numerous supports are distributed over a surface and vertically adjusted, and on the supports carriers are placed, which usually extend in a first horizontal direction.
  • On this carrier numerous other carriers are placed, which extend in a second horizontal direction.
  • Numerous shuttering panels are placed close to each other on the last mentioned supports in order to be able to cast a concrete ceiling thereon, for example.
  • From the DE 44 31 145 A1 is a height-adjustable support for a slab formwork, in which the outer tube is provided in the region of a bottom plate with a flared portion having a larger outer diameter.
  • the DE 76 36 864 U1 relates to a height-adjustable support with an outer tube whose head or foot has a so-called approach, which may have a bead of larger diameter.
  • US Pat. No. 2,508,779 A1 relates to a support for the building with an inner and an outer tube in which the inner tube is telescopic, the outer tube is screwed into a socket which is accessible from the outside in use and has, seen in cross section, four wave-shaped projections.
  • the invention has for its object to provide a support in construction, which is suitable to meet the requirements placed particularly well. Furthermore, a method for their production is to be created.
  • this has a tube which is axially profiled in at least one end region, which is externally accessible in use, and whose outer and / or inner diameter and / or wall thickness is increased in at least one end region compared to the rest of the tube ,
  • the inner diameter and / or the wall thickness of the described end region is particularly stable. This is particularly advantageous especially for the lower end region, because here the described impacts are applied for adjusting the support.
  • the advantageous effect is essentially that the stability in this area is improved. This means that the pipe can better withstand the impacts described, and deformations become much less likely.
  • the axial profiling interacts with the above measures in many ways. On the one hand, this visually shows the user the area which is amplified in order to achieve the above-mentioned effects. The user gets signaled by the axial profiling in optically easily recognizable manner, where the required shocks are applied. As a result, these impacts can be limited to the area in which the tube is particularly stable, and impairments of functionality by impacts in unsuitable zones are significantly reduced. Second, it has been found that the axial profiling contributes to the stability of the tube. In other words, even if the outer and / or inner diameter is increased only in places, namely according to the axial profiling, this contributes to the stability of the tube and the resistance to deformation.
  • the force is introduced by the axial profiling in a particularly favorable manner in the wall of the tube when applied to this blows, so that for this reason the likelihood and extent of dents on the outside and bulges on the Reduced inside.
  • the introduction of force is to some extent tangential in the direction of the pipe circumference and to a lesser extent radially, which would lead to the dents described.
  • the axial profiling advantageously has the effect that dents and the like visually appear significantly less.
  • the appearance of the tube becomes even after prolonged use improved because unavoidable dents and other damage are much worse visible than a smooth-walled pipe.
  • the axial profiling advantageously leads to a microstructural change, in particular a microstructural compaction of the steel used, so that the tube therefore also acquires an increased strength.
  • alloyed steels having a defined carbon content and / or manganese as the alloying element are preferred for the outer tube of the support according to the invention.
  • the tube is profiled axially and in which its inner and / or outer diameter and / or wall thickness is increased, a range of 15 cm to 20 cm, measured from the lower end, has proven to be particularly advantageous.
  • the bumps for displacing the support are particularly effective because they are applied comparatively close to the lower end of the support, so that it shifts and in a favorable manner, a vertical adjustment can be achieved.
  • the lower end is in use in the area of the floor, the ground or the building ceiling on which the pipe is placed, and may for this purpose have a foot plate.
  • the described range can be at least in the mentioned zone of 15 cm to 20 cm, measured from the lower end, it can extend significantly further. It has proved to be advantageous if he is up to a few inches from the lower end and / or extends to a point 30 cm from the lower end. If the lower end itself is not axially profiled, this offers the advantage that the attachment of a plate, in particular a foot plate of an outer tube, preferably by welding, is facilitated. However, the enlargement of the inner and / or outer diameter and / or the wall thickness can also be provided in this area. The same advantage applies to the case that the teaching of the invention is applied to the inner tube, which is usually the upper tube and accordingly has a top plate.
  • Particularly preferred is currently an embodiment in which the inner and outer diameter is increased, but the wall thickness, compared to the rest of the tube remains the same.
  • particularly good properties could be determined.
  • a particularly favorable production method could be developed, in which the area in question is first compressed to increase the wall thickness, and the tube is subsequently widened at the inner and outer diameter, so that at least almost the same wall thickness is established in the widened region like the rest of the pipe.
  • the profiling is seen in cross-section largely wavy. Such a shape ensures a visually appealing and harmonious design.
  • the waveform also prevents the formation of zones where voltage spikes could form.
  • this can provide a support that is particularly well suited to the requirements.
  • expansion and / or axial compression take place in order to form the described end region.
  • Particularly favorable results are shown when initially an axial compression takes place in order to increase the wall thickness, and subsequently an expansion is carried out to increase the inner and outer diameter, the resulting wall thickness at least substantially equal to the wall thickness of the remaining tube.
  • the profiling can take place one or more times before, during or after swaging and / or swelling.
  • the further preferred embodiments of the method according to the invention correspond to the preferred embodiments of the support produced therewith.
  • the area immediately at the edge of the pipe can be smoothed, rounded and / or formed into a cylinder to connect to a foot or head plate , For example, by welding, to facilitate.
  • Fig. 1 is shown in a perspective view of the lower portion of a tube 10 of a support in construction. In the illustrated embodiment, it is an outer tube having a base plate 18 at its lower end.
  • the area mentioned is designed to be axially profiled, and in the case shown both its outer and inner diameters are increased compared to the rest of the tube.
  • the wall thickness is approximately equal to the wall thickness of the remainder of the tube.
  • a lowermost region 16 in other words adjacent to the foot plate 18, is not enlarged and not profiled, so that attachment of the tube to the foot plate in this region can be accomplished particularly easily.
  • Fig. 12 is a sectional view of the specially shaped portion 12.
  • the axial profiling is designed substantially as a waveform.
  • the wave crests 14 present on the outside are slightly flattened, so that in each case two edges 20 result.
  • the force can be transferred very well by a hammer, and this is introduced into the pipe wall in a tangential manner tangentially.
  • the wave crests can be flattened on the inside and accordingly provided with edges.
  • the smallest inner diameter in other words the inner diameter, which results from the wave crests on the inside, compared to the rest of the tube is widened.
  • the effect can be obtained that even in a case where a dent on the outside of the tube leads to a bulge on the inside, the movement of the inner tube is not hindered and, accordingly, the telescopability is maintained.
  • the axial profiling can be described as leading to substantially axially extending ribs with intervening grooves.
