Definitions

  • the invention relates to composite profiles, in particular supports, formed from concrete and at least one steel profile, the open chambers being largely filled with concrete and the outer surfaces of the flanges being exposed. H. are not covered with concrete.
  • Such composite profiles are used in the construction of houses, halls, warehouses, etc. if fire resistance is to be achieved.
  • DE-OS 2 829 864 describes a composite profile, which on the flange outer sides, i. H. has no concrete outside the profile outline.
  • the chamber concrete is non-positively connected to the inside of the steel profile by welded compound in order to avoid detachment of the chamber concrete both at room temperature and at fire temperature.
  • Steel profile cross-section, concrete cross-section and reinforcement steel cross-section contribute proportionately according to their surface area and their temperature-dependent strength. In the event of a fire, the temperature rises and the load is continuously shifted from the steel section to the reinforced concrete section, primarily due to the softening of the flanges, which make up the majority of the steel section.
  • the invention has for its object to provide a composite profile of the type mentioned, which avoids the disadvantages mentioned above and is characterized by increased load-bearing capacity and fire resistance with approximately the same external dimensions.
  • this composite profile should be characterized by a targeted height-dependent load capacity.
  • the composite profiles according to the invention which are constructed either from common hot-rolled profiles or from welded special profiles and from flat iron, have large masses of steel in the fire-protected area.
  • the flat bars which can be stored easily and in a space-saving manner, are either connected to the profiles at the factory or on site.
  • the load-bearing capacity of the profiles which can have minimal dimensions for the respective application, is specifically increased by means of the flat iron, while at the same time the load-bearing capacity is increased proportionally in the event of a fire.
  • FIG. 1 you can see an H-profile 1 whose chambers are filled with concrete 6.
  • Flat bars 2 are welded onto both sides of the web.
  • the welded joint 5 can be made continuously or by spot welding.
  • Structural steel mats 3 provided with longitudinal reinforcement bars 4 are welded to the side of the flat bars 2. These prevent the concrete from flaking off due to heat.
  • the flat bars can have a thickness between 10 and 80 mm. In order to allow problem-free welding, the width of the flat iron is approximately 10 cm less than the web height. If the available flat bars are shorter than the profiles, several pieces are butted together.
  • the flat bars should advantageously cover about 70% of the area of a web side.
  • two flat bars arranged in parallel can be welded to the web of the profile.
  • the two flat bars can be arranged continuously, symmetrically or eccentrically.
  • the flat iron 22 can extend over the entire height of the profile 1, while the flat iron 22a only extends to the level of a change in load, which is caused, for example, by ceilings can be.
  • FIG. 3 shows a further possibility for fastening the structural steel mats 33 provided with longitudinal reinforcement bars 34 on the flat bars 32.
  • the headed pin dowels 38 are connected to the flat bars by means of electrical spot welding and the mats are suspended in the dowels. The concrete then poured into the profile chamber causes the mats to be attached to the flat iron using the dowels.
  • the composite profile shown in FIG. 4 comprises a plurality of flat iron 42 arranged one above the other on both sides of the web, which means. Screw pins 48 and nuts 49 are attached to the web of the profile 1.
  • the number of flat iron 42 used can be selected depending on the required load and fire resistance.
  • the structural steel mats or reinforcement baskets 43 provided with longitudinal reinforcement bars 44 are connected to the profile, similarly as set out above for the dowel fastening, by means of screw nuts or related elements 49a screwed onto the screw pin ends.
  • this embodiment leads to a composite profile which has different, for example height-dependent, properties with identical external dimensions. This profile is also ideally suited for construction on site.
  • both the profile 1 and the flat iron 42 are advantageous to provide both the profile 1 and the flat iron 42 with the required perforations in the factory.
  • the profile is placed on the floor in such a way that both flanges lie on it.
  • the structural steel mat 43 is then inserted and the elements 49a are turned onto the screw pin ends; the concrete is poured into the open chamber, formwork preventing it from running out at both open ends.
  • the concrete is advantageously vibrated. After the concrete has solidified, the composite profile is turned over and the same process steps are repeated. If you want to reduce the amount of reinforcing steel or avoid it altogether, it is recommended to use colloidal concrete or fiber-reinforced concrete instead of normal concrete.
  • Fig. 5 shows a longitudinal section through a profile on the web flat iron 52 are fastened by means of screws 58 and nuts 59.
  • Raw screws as well as fitting screws or high-strength screws can be used as screws.
  • the preparation of the friction surface can be carried out using shot blasted steel, sand or flame.
  • the friction coefficients of the contact surfaces can also be increased by non-slip coatings or corrugation.
