Definitions

  • the present invention relates to a connecting device with a horizontally arranged, frame-like edge support for connecting a concrete ceiling to at least one support and a structure with at least one device.
  • a column head for connecting a solid concrete ceiling to a steel profile column with a vertical passage for utility lines in which construction the head part of the steel profile column is provided with vertical, wing-like steel sheets.
  • an anchoring part is provided, which consists of rows of stud bolts which are welded to the wing-like steel sheets of the steel profile support.
  • This prop head avoids peak loads, which in particular due to the anchoring part, which consists of dowel bolts. (DE-OS 29 20 044)
  • This column head can only be used for steel profile columns; the basic idea disclosed is therefore not to be used for pure iron-reinforced concrete structures.
  • the headed dowels used are only used for laying on and not for mechanical connection with concrete reinforcing bars.
  • a reinforced concrete ceiling with at least one vertical support has also become known, in which the connection of the ceiling and the support or supports at or at each connection point is formed by a horizontally arranged element made of steel profile and having at least two angles to one another. The free legs of this element are connected to one another by at least one steel link. Concrete-free space for the passage of lines exists between the legs of the horizontal element and the associated steel connecting link. (CH-PS 430 128)
  • a metallic column knob which serves as a connecting element between a supporting column on which it is fastened and an armored concrete slab, in which slab it is cast.
  • This column knob consists of several rods which are welded together and which circumscribe a polygon, the ends of the rods projecting from this polygon being self-supporting. These bars or profiles are provided with pins pointing towards the inside of the polygon, which are used for anchoring in the concrete. (CH-A-596 399) That as a composite element serving U-profile also has an upper horizontal continuous leg, which is difficult to introduce reinforcements.
  • the prior art also includes a support device of an reinforced concrete ceiling provided at least with a vertical steel support, wherein a horizontally arranged element made of a steel profile and having at least two angles to one another is used to connect the ceiling and support at the connection point, the leg of which is formed by at least one steel element are connected to each other to form a steel mushroom.
  • a support device of an reinforced concrete ceiling provided at least with a vertical steel support, wherein a horizontally arranged element made of a steel profile and having at least two angles to one another is used to connect the ceiling and support at the connection point, the leg of which is formed by at least one steel element are connected to each other to form a steel mushroom.
  • the present invention aims to provide a connecting device which has a lower steel consumption compared to the prior art, ensures an effortless, safe insertion of reinforcing steels of the concrete ceiling, creates advantageous force relationships in the area of supporting the ceiling on the support and is environmentally friendly.
  • Such a connecting device is characterized by the wording of claim 1.
  • FIG. 1 shows a support 1 with a concrete ceiling 2, in which construction no special measures for transferring forces from the concrete ceiling 2 into the support 1 are provided, that is to say in particular also no support head. Then the Known outbreak 4, which can collapse the ceiling.
  • FIGS. 2 and 3 shows a support 16 with a frame which serves as an edge support 19 and is made of flat steel, glass fiber reinforced plastic or the like. Furthermore, outer and inner composite means 20 and 24 are arranged in a hedgehog-like manner projecting outwards and inwards from the edge carrier 19.
  • the force on the concrete is represented in a purely ideal way as a force-conducting pressure strut 27, without installing a cross 17, in the support 16.
  • Any moments as well as forces not taken over by concrete pressure struts can be transferred from beams by installing a cross 17.
  • the construction according to the invention is shown with a support 16 and a frame 28 made of a Z-profile as an edge support.
  • a cross 17 and a pressure plate 21 can also be provided here.
  • the edge support 19 can therefore be operatively connected to the support 16 via concrete pressure struts 27 or steel profiles in the form of the cross 17.
  • 5 to 12 show different variations and applications of devices according to the invention when supporting concrete ceilings.
  • the forms square, rectangular, polygonal, circular, oval or other shapes are provided.
  • Fig. 13 shows excerpts, among others. 2 and 4, in different versions.
  • Edge supports 19 and 28 with or without additional supports 17 arranged in the cross 17 or laid in the diagonals can be used as main structures.
  • Shapes can be used for these flat or wide flat sheets, double T or T rolled profiles or other types of composite profiles and composite structures made of appropriate materials.
  • the edge beams 19, 28, shown here as flat bars or Z-profiles, can also be designed as L-profiles, as box profiles or in any composition or as composite structures.
  • FIG. 14 shows a section of a reinforcement guide for a structurally perfect anchoring.
  • the edge girder 19 with the composite means 20 is concreted in a concrete ceiling 18, as is analogously e.g. is explained with reference to FIGS. 2 and 3.
  • the ceiling 18 is reinforced by means of reinforcing steels 30. It can be seen from the illustration how the U-shaped reinforcing steel is connected here via the composite means 20 to the edge support 19, the outer surface 31 and inner surface 32 of which are designated in FIGS. 2 and 14.
  • This embodiment allows a flawless, clear transfer of forces from the ceiling 18 in the support 16. Thanks to this new construction, the troublesome problems with the lower reinforcement, here in the form of steel 30, are finally a thing of the past with regard to anchoring, cutting lengths and welded connections; because the composite means, for example in the form of bolts 20, are not welded to the reinforcing mesh, the bottom of the U-shaped steels 30 preferably touching the frame.
  • Flat or wide flat sheet is normally used for the head plates.
  • Their shape can be square, rectangular, circular or star-shaped. But it is also possible without constructing these head plates and dimensioning the crosses accordingly.
  • the devices according to the invention allow horizontal and vertical cutouts in the ceiling. They are particularly suitable for medium to large loads, but are material and therefore cost-saving for them. They form complete units with a relatively small installation weight and are inexpensive in every respect. They also comply with the SIA 160, 162 standard.
  • the inner connection means 24 must be closer to the upper end plane of the ceiling, which is normal to the support, than the outer connection means 20, so that the pressure forces introduced into the pressure strut form a minimum inclination angle ⁇ with this end plane, which is greater than 25 according to SIA standards ° should be. If this angle becomes too small, several frames with composite materials must be provided to ensure that the forces are applied at an angle> 25 ° to the support.
  • the new construction explained in detail offers the greatest possible degree of safety and improves the bending strength in the contact area.
  • it enables perfect reinforcement management and thus optimal force transmission. It is therefore particularly well suited for absorbing high punching loads.
