Definitions

  • the invention relates to components with the help of forces on joints of steel and Prestressed concrete structures can be conducted.
  • the elements consist of kinked rods or sheets that either individually or assembled from several parts.
  • the elements are with shear forces and bending moments and in sections also stressed with normal forces.
  • An essential feature of the construction according to the invention is the kinked shape. This initially ensures that the concrete is always on the load-bearing side supported from below and the loads on the load-bearing side from above in the construction can be initiated. This makes the pressure-resistant concrete in stressed primarily with compressive stresses, which always makes a comparative high load-bearing capacity of the construction is guaranteed.
  • Another advantageous feature of the construction according to the invention exists in that they are positively connected to the concrete at the corner or end points is, so that pairs of forces for the balance of arising bending moments into the concrete.
  • the elements preferably have rectangular cross sections. Compared to Round cross sections can, on the one hand, depending on the arrangement, the bending stiffness be minimized or maximized so that for the desired load-bearing capacity (mostly normal forces or mostly bending moments) always optimally acting Cross sections can be selected. Particularly favorable load capacities can for absorbing bending moments can be achieved if the bars made of L-, U-, T, TT, I-shaped or similar composite cross sections exist.
  • the rectangular or composite rods can be individually, in pairs or installed in series with or without gaps. Will two or more rectangular bars arranged side by side can be reached thus particularly favorable for the absorption or transmission of the forces in the concrete Conditions, since the concrete is exposed to several small sub-areas tolerates greater local stresses.
  • the task of transferring, in particular, vertical transverse forces via joints is solved according to the invention by claim 1.
  • the invention provides that bent bars or sheets in the form of simple, two-legged hooks or bridge the joints with approximately Z-shaped double hooks. Each in the latter case, the middle part is vertical or inclined according to joint width arranged. With this form it is first achieved that both on the load-bearing as well as on the load-bearing side of the concrete Pressure is claimed. Elaborate additional reinforcements are not necessary.
  • FIG. 1 shows the longitudinal section through a reinforced concrete or prestressed concrete construction in which two components 1 and 2 are separated from one another by a relatively narrow joint 3.
  • the load of the component shown on the left is with the inventive -shaped support element 4 introduced into the right component.
  • a sleeve 5 can first be installed in the left component, into which the support element is inserted after stripping. In this case, the support element on the underside of the sleeve z. B. locked with a knob 6.
  • the support element consists of two supports arranged side by side, which are connected at the top to a belt plate 9. The support forces can be released from the support element either directly onto the concrete or - as shown in the drawing - via a sound-absorbing intermediate structure 10.
  • FIG. 2 shows a device according to the invention with a support element 11 shown that the loads of the left component via an expansion joint 12 on the right component should transfer.
  • the support element is mounted on one side in a sleeve 13.
  • a load introduction plate can be on the sleeve 14 are arranged.
  • the bending stress of the support element can be optimally designed by the support element in addition to the actual Load introduction area to the left further into the concrete and here with the help of Sleeve and one welded to this welded 15 is anchored upwards.
  • the concrete is lifted by the load at the bottom left and the load delivery at the top right each favorably stressed; there are no complex additional reinforcements needed.
  • the forces are favorable in the concreted part of the support element initiated with the aid of the recesses 16 arranged in the carrier, so that here none additional pressure plates or tension anchors are required.
  • the supporting element is supported by the lower right end face 17 of the transmission against the right concrete body.
  • the upper right part of the Carrier element an equal tensile force.
  • the resulting moment takes a substantial part of the resulting offset torque. Overall will due to the chosen shape and the arrangement an extremely favorable carrying behavior reached.
  • FIG. 3 shows a further variant of the device according to the invention, which are preferably used to absorb and forward support forces relatively wide insulation joints 18 can be used. With wide joints it offers to arrange the central part 20 of the support element 19 inclined; thereby this part of the beam is used very cheaply almost exclusively with normal forces.
  • both sides of the support element are firmly concreted in shown.
  • the load-bearing capacity of the parts concreted in corresponds to that the right part in Figure 2.
  • FIG. 4 shows a variant of the invention shown in FIG. 1 Support element 4. It differs on the one hand in the curved shape of the lower, left, load-bearing part 21 of the construction. Through the curved The knob 6 shown in FIG. 1 and the associated bolt are unnecessary in shape 7. As a result of the curved shape, a horizontal one pointing to the right can still occur Force component from the support element through the sleeve into the concrete will.
  • the support element according to the invention shown in FIG. 4 differs from that in Figure 1 by connecting the two arranged side by side Carrier through a threaded sleeve 22.
  • the Carrying element according to the invention can also be used as a transport anchor.
  • FIG. 5 shows a further variant of a support element according to the invention, this is used to advantage in both small and medium joint widths can be.
  • the loads of the left component are from the invention Carrier with the help of the numerous contact surfaces between carriers and concrete added through the openings 23 and the rounded Surfaces 24 of the support element are given.
  • the resulting offset moment maintains equilibrium through a horizontal pair of forces with which the support element presses against the concrete at the top left and pulls to the right at the bottom.
  • Of the Concrete transfers the lower tensile force with compressive stress into the usual inserted reinforcement.
  • FIG. 6 shows an additional variant of a support element according to the invention 26, which is preferably used for the reception and transmission of support forces relatively wide fingers can be used. Similar to the support element 25 according to Figure 5 are rounded for opening and delivery of loads through openings 23 and Surfaces 24 achieved particularly favorable conditions. For receiving of the offset moment, the element is supplemented below by a pressure rod 27, which releases the pressure force via a pressure plate 28 in the right-hand emphasis.

  • fastening aids e.g. as a molded part Plastic
