Definitions

  • the invention is based on a connecting and pressure distribution element for two components to be concreted in succession on a horizontal base in the same plane, which are to be separated from one another by a dilatation joint, with a sleeve and a mandrel which can be slid into the sleeve, both about the Sleeve as well as around the mandrel and at a distance therefrom are each arranged at least two self-contained brackets made of reinforcing bars, which are firmly connected to the sleeve or the mandrel, which sleeve is to be fastened to a face formwork and to be inserted with the brackets in the first the component to be concreted and the mandrel are intended for insertion into the sleeve anchored in the first hardened component and for insertion with the brackets into the component to be concreted later.
  • connection and pressure distribution element is described in European Patent Application No. 0119652.
  • connection and pressure distribution elements are namely used to connect building or civil engineering components, such as roof panels, floor panels, ceilings, walls, supports, retaining walls, or highways or landing strips of the airfields, which components are to be fixed in exactly the same plane. The components connected by such an element are exposed to the influence of different temperatures and pressures, so that they should expand and contract in the direction of a joint.
  • the invention specified in claim 1 has for its object to provide a connection and pressure distribution element that allows different mandrel diameters to be used without having to replace the sleeve bracket with the corresponding diameter sleeve. This further allows such brackets to be kept in stock and not to be welded onto the sleeve when the sleeve is changed.
  • connection and pressure distribution element according to the preamble of claim 1 by the features of the characterizing part of claim 1.
  • the webs with the tube are advantageously one-piece longitudinal ribs, each steel ring having an inside diameter which corresponds to the outside diameter of the longitudinal ribs.
  • the element shown in the figures serves to connect two components 2, 3 to be concreted one after the other on the horizontal base 1 in the same plane, which are to be separated from one another by a dilatation joint 4, as is the case in particular in the case of motorways or airfield railways.
  • the element embedded in the components enables the components to be expanded and contracted freely, which components are exposed to different temperatures. Furthermore, the element serves to distribute the forces that occur in particular when the components are expanded and contracted over a larger area in the concrete.
  • the connecting and pressure distribution element consists of a sleeve 5, a mounting shoe 16 and a mandrel 6 which can be slid into the opening of the sleeve 5.
  • the sleeve 5 comprises a tube 9 with at least three webs arranged symmetrically around the tube and parallel to its longitudinal axis x 10 of the same height. Furthermore, the sleeve 5 comprises at least two steel rings 11 which are pressed onto the webs 10. On each steel ring 11, a bracket 7 is welded from the outside, which is designed in a spiral shape. Each bracket 7 consists of reinforcing bars, the thickness of which is, however, smaller than the thickness of the bars of the basic armoring 20 (FIG. 6).
  • the tube 9 carries a flange 12 running perpendicular to the longitudinal axis x of the tube 9.
  • the tube 9 carries a height-adjustable support rod 13 which can be fixed at the desired height by means of a nut 14.
  • the support rod 13 also extends perpendicular to the longitudinal axis x of the tube 9 in a bore in a screw 15, on which the fixing nut 14 is arranged such that it can be screwed.
  • the webs 10 are integral with the tube 9 longitudinal ribs.
  • the at least two steel rings 11 have the same inside diameter as the outside diameter of the longitudinal ribs. From the For this reason, the steel rings 11 must be pressed onto the longitudinal ribs by means of a press or by hammer blows.
  • the brackets 7 are welded onto the steel rings 11.
  • the inner diameter of the tube can be different, the height of the webs 10 also varying.
  • the steel rings 11, which all have the same inner diameter and on which the brackets 7 are welded, can thus be pressed onto pipes of different inner diameters.
  • the steel rings 11 with the welded-on brackets 7 can thus be kept in stock in larger quantities.
  • the tubes 9 of different inner diameters are then used for mandrels 6 of different diameters.
  • the assembly shoe 16 shown in FIG. 2 has a U-shaped recess 17, which is intended to receive one end 9a of the tube 9.
  • the assembly shoe 16 is fastened to the front formwork 8 by means of nails; for this purpose 16 nail holes 21 are provided in the mounting shoe.
  • the face of the assembly shoe 16 facing the face formwork 8 is offset inwards around the recess 17 for receiving the flange 12 of the tube 9. This insertion recess is designated 22.
  • the assembly shoe 16 On its surface facing away from the face formwork, the assembly shoe 16 is provided with two anchoring ribs 18, each of which lies on the opposite side of the recess 17. These anchoring ribs ensure good anchoring in the concrete of the first component 2.
  • the side edges of the assembly shoe 16 have centering slots 19 for facilitating the fastening of the assembly shoe 16 to the face formwork 8.
  • the side edges of the assembly shoe 16 are chamfered on the surface to be turned towards the face formwork 8 in the direction of the recess 17. A good anchoring of the assembly shoe 16 is achieved after the end formwork 8 has been torn off from the first hardened component 2.
  • the support rod 13 is made of steel with a diameter of approximately 5 mm. It is carried out by a screw 15 and adjustable in height; it serves as a support for the other end 9a of the tube during the insertion of the sleeve 5 into the first component 2. This support absorbs the pressures of the cast concrete of the first component 2, so that the sleeve 5 is not displaced from its position.
  • the two components 2, 3 are shown with the recessed sleeve, mounting shoe and mandrel in section.
  • the front formwork was torn off from the first hardened component 2 and the mandrel 6 was inserted into the opening of the sleeve 5.
  • the second component 3 was concreted and the mandrel 6 embedded in the same.
  • the dilatation joint 4 between the components 2 and 3 is also visible here, which was created after the front formwork 8 was removed. This dilatation joint is filled with insulation material.
  • the connection is established.
  • the mandrel 6 with a diameter of 16 to 40 mm, which must correspond to the diameter of the opening of the sleeve 5, is slidably inserted in the sleeve.
  • connection and pressure distribution element described above is manufactured entirely in a factory. At the construction site, it will only be adjusted in height and folded. Assembly is very simple because only the assembly shoe is attached to the front formwork at the desired height and the sleeve with its flange is inserted into the insertion recess of the assembly shoe. The other end of the sleeve is supported by the support rod at the desired height. This means that the sleeve can no longer fall down during assembly of the heavy basic reinforcement.
  • the brackets achieve a better distribution of the pressure in the two components.
