Definitions

  • the invention relates to a device with the zugbe pipete components without Welded or direct mechanical connections of extremely short length development can be connected to one another in a force-transmitting manner.
  • the device according to DE 957 685 C is further characterized in that it can only be used if the reinforcement is arranged in ducts and thereby can be stretched. It is therefore not suitable for connection of reinforcement, which was immediately concreted in and with the concrete in the Verbund lies.
  • the device according to DE 36 34 568 A1 may deviate from this Although used for embedded concrete reinforcement, but required for installation a comparatively large joint width, which in addition to the multipart, comparatively consuming construction represents a significant disadvantage.
  • the object of the present invention is under tensile stress with a correspondingly designed, in a particularly simple molded device to connect rod-shaped devices, without further measures having a minimum length of development of a force-absorbing structure.
  • the tension rods can consist either of rod-shaped reinforcing steels or else of other materials and / or other cross sections.
  • the elements to be pushed tensile elements are bent in loop form and overlapping installed .
  • the loops devices made of steel or other suitable materials are installed, which are circular or annular at least on one side, so that they direct the deflection of the already mentioned Buchlenkungen or indirectly -. B. on the concrete - can record.
  • These forces can be passed on to the further construction with the same method; Depending on the initial situation, however, the force transmission can also be ensured elsewhere, for example by means of welded joints.
  • the overlap ensures that the length development of the tow joints can be kept extremely small. This is a very significant advantage, as this building joints, in which the pull is to be installed, can be formed with a small joint width. This leads to significant functional and economic benefits.
  • the overlap allows the formation of particularly simple and small connectors, which also ensures economic and functional advantages.
  • the device may preferably be used in steel and prestressed concrete structures, wherein the short length development is particularly advantageous, in particular in connection with structural joints over which tensile forces are to be transmitted. With the device but also tensile forces of components made of other materials (such as, for example, wood or steel) are passed into the concrete. Finally, the device can also be used favorably for the transmission of tensile forces between wood and steel or other suitable materials.
  • the tensile to colliding components can have a height offset on exhibit. This can be a significant advantage in certain applications of steel and prestressed concrete construction - namely, if different sized concrete cover dimensions are to be observed for the reinforcements to be repelled (eg reinforcing steel and stainless steel).
  • the connecting element can be designed so that both reinforcements are installed in each case with their specific concrete cover and thus have the respective maximum possible lever arm for receiving bending tensile forces.
  • the resulting offset moment can be compensated solely by the fact that the loops are supported at right angles to their plane against the concrete.
  • the intermediate elements can be formed due to the height offset so that the resulting during the transmission torque offset moment is maintained by a counteracting force pair in equilibrium.
  • FIG. 1 shows an example of this situation in a longitudinal section through a Reinforced concrete slab, like the reinforcements 1 in the area of a shrinkage gap 2 with the help of the devices 3 according to the invention with the further reinforcements 4 tensile strength can be connected.
  • Shrinkage joints are arranged in structures where due to the structural constraints due to shrinkage of the concrete would be large compulsory loads. They become one closed as late as possible after completion of the shell work. While the width of the shrinkage joints in conventional training Overlapping impacts is relatively large and so too unwieldy for many operations is the follow-up work at the short joint width shown here almost be carried out unhindered.
  • Figures 2 and 3 and 4 and 5 each show a slightly modified variant the device of Figure 1, in which it is possible, initially only the two Reinforcement loops 1 and 4 sufficiently accurate fit - if necessary, with a sufficient Tolerance measure for Schwindverkürzungen - to install.
  • the circular cylinder molded connector 3 can be used later. In other applications such as For joints with thermal separation, it may be against be useful, the connector with that loop through the Dämmfuge is already connected before installation.
  • the loop 1 pulls to the left and accordingly the loop 4 to the right.
  • the resulting due to the height offset of the two loops offset moment wants to turn the connector clockwise.
  • this is prevented by the fact that the loop 1 is supported at the point A down against the concrete. Due to the comparatively low tensile strength of the concrete, however, it is often not possible for the point B of the loop 4 located near the concrete surface 5 to support itself in the same way. Therefore, in the example of FIG. 3, the lug 5 arranged on the circular ring serves to accommodate this upwardly directed force required for the equilibrium.
  • FIG. 6 shows, as a further possible variant, the applicability of the invention Device the rigid connection of wooden beams 11 to a Reinforced concrete slab 12 in the area of a thermally insulated joint.
  • the bending tensile forces occur here in the upper region of the wooden beam 11.
  • the inventive Device for transmitting tensile forces is therefore in the upper range arranged.
  • the occurring in the lower region of the cantilevered wooden beam 11 Bending forces and the shear forces are provided by a designated Pressure plate 18 recorded, the horizontal and vertical support surface components has and by means of a diagonal arrangement, the transverse forces and forwards this can be connected to the pull loop 15.
  • the two printing plates are here about roof-shaped inclined against each other.
