Definitions

  • the invention relates to a load-bearing, area-forming sheet metal profile element, in particular roof element for the production of hall roofs.
  • Elements of this type are known as so-called trapezoidal profile sheets. They consist of a large number of support flanges and belts which are offset in height from one another and which are connected by means of webs to form a meandering sheet metal profile formed from a large number of trapezoids arranged next to one another. Such profiles are used for covering rooms and roofs by placing them side by side over purlins or trusses.
  • the roof structure is applied to roofs thus formed, e.g. a multi-layer layer consisting of bitumen roof slabs is applied and sprinkled with a layer of gravel or covered with a roofing film.
  • the channel-shaped troughs of the trapezoidal sheets are poured out with concrete.
  • Sheet metal profiles with a trapezoidal cross-section are also known, which are formed from two outer support flanges, webs emanating from them and a single upper flange connecting the webs, impressions or bulges arranged at a distance from one another transversely to the longitudinal extension of the elements.
  • these trapezoidal profiles as described, for example, in AT-PS 345 525 or GB-PS 1 249 997, have only a low bending stiffness in the transverse direction, which is why their assembly is difficult and requires considerable effort. It is necessary to use bearing plates with webs and base flanges spread by special brackets as assembly aids when laying such profiles, which increases the sheet metal work and the weight accordingly and complicates the assembly.
  • the invention aims to avoid the described difficulties and disadvantages and has as its object an improvement over the known elements To create a ratio of resilience to dead weight, but increasing the rigidity in the transverse direction, stabilizing the angle between the top chord and web and no additional aids are required during assembly.
  • the invention solves this problem in a load-bearing, area-forming sheet metal profile element, in particular roof element for the production of hall roofs, with two outer support flanges, two webs extending from these and a top flange connecting the webs, the transverse embossments arranged at a distance from one another transversely to the longitudinal extent of the element has, characterized in that between the transverse embossments of the upper chord on the upper chord and on the lateral webs extending around the edges, transverse embossments are provided which extend transversely to the longitudinal extent.
  • transverse embossments in the upper flange expediently end at a predetermined distance from the webs, whereas the ends of the extending in the upper flange. Corner embossing that grips behind the cross embossing.
  • the flat, undeformed part of the upper flange between the transverse and corner impressions advantageously extends in a meandering fashion over the entire length of the element.
  • This meandering course of the flat part of the top chord between the transverse and corner impressions in the chord means that the course of forces is not interrupted, which in turn enables material to be saved by using sheet metal in smaller sheet thicknesses.
  • a preferred embodiment of the invention is characterized in that the parts of the corner impressions extending into the webs over at least a third of the web height is sufficient.
  • Fig. 1 shows a diagonal view
  • Fig. 2 shows a section along the line II-II
  • Fig. 3 shows a section along the line III-III.
  • Fig. 4 the laying of such elements as a roof structure or as a floor ceiling is shown graphically.
  • the element 1 according to FIG. 1 consists of the two outer support flanges 2, 2 ', the inclined webs 3, 3' and the upper flange 4 connecting these webs.
  • These transverse impressions 5 could also be designed as elevations.
  • groove-shaped corner impressions 7, which run around the edges and extend around the edges, are also embossed with a smaller depth than the beads 5. Instead of the corner impressions 7, bulges could also be present.
  • the parts of the corner embossments protruding into the webs expediently extend over at least a third of the web height 9, in the exemplary embodiment shown up to about half the web height. ⁇
  • the transverse embossments 5 and the corner embossments 7, 7 ' engage in a "tooth-like" manner, whereby they reach behind the dimension 10, viewed in the longitudinal direction of the element.
  • the transverse impressions 5 each end at a distance 11 in front of the edges 6, 6 'and are each arranged at a distance 12 from the corner impressions 7, 7', so that the flat undeformed part of the upper flange 4 meanders between the transverse and corner impressions extends over the entire length of the element. This ensures that the force curve on the upper flange is not caused by the impressions 5; 7, 7 'is interrupted, so that a further material saving is possible by using even thinner sheets with the same load capacity.
  • FIG. 4 shows how several elements 1 are placed over support profiles 13, 14 and joined together with the flanges, the guide grooves 8, 8 'of adjacent elements coming to lie one above the other. This results in a firm association.
  • the troughs 15 formed between adjacent elements can be poured with concrete, the corner impressions 7, 7 'preventing the concrete from migrating relative to the elements. It can also be placed over the straps 4, depending on the load that occurs, in which case the transverse embossments 5 further increase the adhesion, so that migration of the concrete relative to the sheet metal profiles 1 is not possible.
  • no auxiliary support devices are used for assembly.
  • a spreading of the webs is also due to the corner embossing, even if the elements are not yet firmly attached to the support profiles, but only when the elements are initially placed on them 7, 7 'and their "engagement dimension" 10 with the transverse embossments 5, even with greater loads, for example by the assembly staff, effectively prevented.
  • the sheet metal profiles designed according to the invention can advantageously be produced from thin metal sheets with thicknesses of 0.75 to 2 mm, the height 9 of the profile, i.e. the vertical distance of the top flange from the support flanges can be 75 mm to 250 mm depending on the load.
  • the weight saving compared to conventional sheet metal profiles, in particular trapezoidal profile sheets - with the same load capacity of the profiles - is considerable, as can also be seen from the following example.
  • a trapezoidal profile sheet was used for a certain predetermined load, which had a width of 625 mm and a height of 100 mm.
  • These profiles were formed in a known manner from four support flanges, six webs and three top chords into a meandering shape.
  • These known profiles were made from a sheet metal strip with a width of 1250 mm.
  • the sheet thickness required for the specified load was 0.88 mm.
  • This sheet profile was replaced on the basis of the same load by an element according to the invention.
  • the height of the profile according to the invention was 175 mm with the same width.
  • the sheet metal profile according to the invention was formed with two webs, two support flanges and an upper flange from a sheet metal strip with a width of 1000 mm and a thickness of 1 mm.
  • the sheet volume for 1 m length is 110 0 cm 3 for the known trapezoidal profile sheet, but only 1000 cm 3 for the sheet profile element according to the invention. This results in a saving of 10% when using the sheet metal profile element according to the invention instead of a previously used trapezoidal sheet metal. This saving is when using inventive Sheet metal profile elements of greater height (for a correspondingly greater load) even larger.
  • the depth of the transverse and corner impressions 5 and 7, 7 'or the height of the bulges can vary widely, from single to multiple sheet thickness, the depth of the transverse impressions 5 advantageously being greater than that of the corner Embossments 7, 7 'in the edge area.
  • the sheet metal profiles according to the invention can be galvanized or surface-coated. In addition to steel, they can be made from light metal alloys. They are fastened with screws or set bolts. In the construction according to FIG. 4, the flanges 2 lying one on top of the other are riveted together.
