Definitions
- the present invention relates to a transverse force mandrel bearing for transmission dynamic loads, consisting of a transverse force dome, a shear force mandrel bearing sleeve and at least one bearing sleeve and a lateral force dome holding storage basket.
- Querkraftdome are connection and pressure distribution elements for two in the same level running concrete parts, separated from each other by a joint are.
- a transverse force mandrel bearing is known which, as usual from a transverse force dome, a shear force mandrel bearing sleeve and a bearing sleeve holding storage basket consists.
- end plates are on the storage basket arranged, the only the fixation of the transverse force mandrel bearing sleeve to a Formwork serve during the construction of the concrete slab.
- the storage basket exists from a number of closed loops of reinforcing steel wires. The Loops lie in planes parallel to the direction of the fugue.
- EP-A-0'032'105 U.C. Aschwanden
- the baskets are here by more or less all-round closed cups formed. Within the cup is doing while the permissible pressure limit of the concrete is exceeded, but the power transmission takes place on the cup and the running above the cup of concrete is so far Relieves that here the permissible pressure limit is no longer exceeded.
- EP-A-0'773'324 A further development is shown in EP-A-0'773'324. Again, this is the Problem of static load and especially the force distribution to Avoidance of exceeding the allowable pressure limit of the concrete considered.
- a stimulus directed towards the joint is also provided here, wherein arranged on each end plate projecting into the building plate is. This plate lies respectively on the side of the dome or the sleeve, when transmitting the static reaction forces to the corresponding Component of the pressure-loaded side of the dome or the sleeve opposite.
- this in the building protruding plates so to speak useless even on the opposite Side to ensure that the element to the static loads even if it is installed inadvertently upside down would.
- transverse force dome Made of inexpensive structural steel and finished with a sleeve or layer To protect stainless steel in order to achieve a cheaper solution overall as with a transverse force dome, which is made only of stainless steel.
- This task meets a transverse force mandrel storage with the features of claim 1.
- the overall concept consists of a lateral force mandrel bearing basket and a more than two-layered lateral force dome and their common arrangement is of essential importance. For the dynamic Loads, these two elements must be coordinated.
- transverse force mandrel bearing The two components under dynamic load, which are connected to one another by means of transverse force mandrel bearings, are here marked B 1 and B 2 .
- Figure 1 a is hinted that the elements are embedded in the concrete.
- the transverse force mandrel bearing is designed symmetrically with respect to the gap F to be bridged.
- the transverse force mandrel bearing consists of the transverse force dome 1, a transverse force mandrel bearing sleeve 2 and bearing baskets 3.
- the storage baskets 3 consist of at least two elements, namely an end plate 4 and a portable belt-like loop 5. It is essential that the traggurtähnliche loop 5 with the end plate 4 together forms a closed force system.
- the end plate 4 is flush with the facing towards the joint end face of the respective concrete part B 1 , B 2 embedded in the concrete.
- the Traggurtartigen loops are arranged so that they are able to transfer the alternating loads occurring on the transverse force dome on the end plate. This is achieved by the Traggurtartige design of the loops 5.
- the portable belt-like loops 5 can be formed in various design forms. They can be exactly the same width as the stim plates 4 or narrower or wider than these. In the embodiment according to FIGS.
- the carrying belt-like loop 5 has the same width as the end plate 4, while the other three embodiments represent variants in which the carrying belt-like loops are narrower than the end plate 4.
- the transverse force dome 1 or the transverse force mandrel bearing sleeve 2 can pass through the carrying belt-like loop 5, as the embodiments according to FIGS. 1 and 4 show or they can be surrounded by these loops 5, as illustrated by the embodiment according to FIG. In both variants, however, the loops 5 have traggurt shame functions. This becomes even clearer in the embodiment according to FIG. 3.
- two support straps are used per side, which together form a closed force system with the end plate 4.
- the possible in the side view forms of traggurtianon loops 5 may for example be trapezoidal, preferably one chooses the shape of an isosceles trapezoid, the height, however, may be different, as indicated by the dashed line in the component B 1 hinted.
- the shape of the Traggurtartigen loops 5 but may also have approximately the shape of a triangle, as shown in FIG 2a. Of course, this shape can also be achieved when the transverse force dome or the transverse force mandrel bearing sleeve 2 pass through the single strap-like loop 5 in each case.
- the Traggurt-like loop be designed semicircular, as shown in Figure 4a.
- the portable belt-like loops are preferably provided with vent holes or vent holes 6 in any size and any number, as shown in the various embodiments.
- shear force 1 For the transmission of dynamic loads is the more than two-layered design of shear force 1 of absolute necessity. Only thanks the more than two-layered design of the transverse force dome can be the achieve physical properties, namely the required Interchangeability coupled with the high compressive strength, shear strength and Elasticity values. Shear force mandrels with monoferritic cross section, d. H. Transverse force mandrels, in their entirety of a metal or a Metal alloy and consist of one piece, have these desired Pairings of physical properties not provided. This realization is very surprising.
- the transverse force domes according to the invention can be used with all common known cross-sectional shapes also produce more than two layers. Still The most common cross-sectional shapes will be present, such as in particular cylindrical lateral force domes and transverse force domes with a rectangular or square cross section. Transverse force domes with a rectangular or square cross section are made of a stratification of at least three formed plate-shaped rods. In this case, the outermost layer as well be enveloping coat formed. Also the connection between the plate-shaped bars to a shear force mandrel can of course be different nature. In addition to adhesive and welded joints come also positive and / or non-positive connections in question. It can packages of plates, similar to multilayer leaf springs, with the individual Bearings, for example, by interspersing rivets or pins form fit be interconnected, or have lateral notches to finally to realize a connection through a strapping.
- a cylindrically shaped Shear force mandrel can be made from more than two layers.
- a special interesting method for producing such lateral force dome is that one slides over a centric cylindrical rod a first tube, which with a certain game surrounds this rod and then its diameter through a Hammering method hammered on the core completely backlash.
- a Hammering method hammered on the core completely backlash.
- the practically purely non-positive Connection is excellent.
- On such a shaped two-ply Kern can easily pull over another tube in the same way be, again with play, again using a Hämmerbacter the new outermost coat hammered on the already two-ply core can be.
- the new outermost coat hammered on the already two-ply core can be.
- can be any multi-layered rod form which can show enormous strength values and its physical Properties practically tailored to each application are.
- the core of the shear force dome is a rod.
- the core is an innermost tube and several Pipes in multiple layers are pulled or hammered over them.
- the cavity of the innermost tube for physical reasons or as Corrosion protection must be filled with a hardening mass.
- the hardness of the more than two - layered dome between the to vary individual layers It is possible both the hardness from the outside increasing and decreasing inside. For various reasons It is particularly advantageous to increasingly increase the hardness from the outside to the inside choose.
