Definitions
- the invention relates to a compliance element for integration in an underground composite construction of channel profiles or lattice girders and a concrete shell according to the features in the preamble of claim 1.
- a compliance element is basically within the scope of EP 1 762 698 A1 known. It is used in the construction of elongated underground structures such as tunnels or tunnels.
- the compliance element is designed so that it can be compressed under the influence of rock pressure. It is honeycomb-shaped and has intermediate layers and spacers which form gaps. The gaps are offset from each other and are reduced when compressed.
- the gutter profiles or lattice girders are embedded by means of shotcrete or shotcrete in a concrete shell inserted on the circumference of the tunnel or the track.
- the known compliance element has basically proven itself in practice. For example, during the construction phase of a tunnel or a route, the person skilled in the art can already see which force from the mountain acts on the composite structure. In particular, however, which force rests on the compliance element. Consequently, a compliance element is mainly used in fault zones or in a pressure rock. The number of each to be integrated in a composite expansion compliance elements depends on the local conditions.
- the invention is - based on the prior art - the object to provide a compliance element for integration into an underground composite structure, which has an increased resistance to the force from the mountains.
- At least one hollow profile is now inserted into at least one tubular body of a compliance element.
- a hollow profile is inserted or whether only in selected tubular bodies hollow sections are provided or whether more than one hollow section is used in a tubular body depends on the local Conditions from. In this case, it is conceivable for the person skilled in the art to insert hollow sections into the tubular body as needed on site. If the local conditions are already known in advance, then the compliance elements can already be appropriately prepared at the factory and provided in a suitable manner with hollow profiles in the tubular bodies.
- the hollow profile is suitably fixed in position in the tubular body according to claim 2. In this way, it keeps its intended position until the composite construction is completed in its entirety.
- the hollow profile consists of a slot tube which is frictionally and positively pressed into the tubular body.
- the hollow profile can also consist of a circumferentially closed tube with preferably circular cross-section, which is clamped by means of fastening elements in the tubular body. But there are also other cross-sections of a hollow profile conceivable.
- the fastening elements consist of fixed in the hollow profile wires.
- two wires such as welding wires, dotted and provided on the opposite ends of the protruding ends with bent legs, wherein the forward leg in the insertion direction are bent by about 160 °, so that they when inserting a hollow profile in a Tube bodies are compressed and slide on the inner wall of the tubular body.
- the legs in the insertion direction are bent by about 90 °. If these legs contact the rear end wall of the tubular body, the legs lying in the direction of insertion are exposed in front of the end face of the tubular body and can spring open, so that the hollow profile is then fixed in position over the legs in the longitudinal direction of the tubular body.
- fasteners consist of insertable between the tubular body and the hollow profile spring steel strips.
- two spring steel strips which are preferably provided in an opposing arrangement, are also bent in two layers and inserted into the gap between the hollow profile and the tubular body.
- inserting the hollow profile in the tubular body slide the spring steel strips in the tubular body and ultimately tense due to the inherent spreading force in the use position, the hollow section in the tubular body.
- a particularly advantageous embodiment of the invention according to claim 7 is that between the support plates at least two layers are provided with tubular bodies and hollow sections inserted therein, wherein between two layers, a separating plate is arranged.
- the number of tube body layers and separating plates required depends on the respective local conditions. For example, three or four layers are conceivable. Also, the number of tubular body with hollow profiles in the individual layers may vary from application point to application point.
- the tube body and / or the hollow profiles in a position compared to the tubular bodies and / or the hollow sections in a different position have different wall thicknesses and / or diameter.
- the upper layer does not provide hollow sections in the tubular bodies, the middle and lower layers but have hollow sections in the tubular bodies, but the wall thicknesses of the hollow profiles in the lower layer are greater than that of the Hollow profiles in the tubular bodies of the middle layer.
- the wall thickness can be varied within the scope of the invention with different diameters of the hollow profiles.
- a combination of the diameter of the tubular body and its wall thicknesses with the diameters and / or Wall thickness of the hollow sections done.
- the number of hollow sections in the tubular bodies may vary from one point of use to another.
- a controlled compliance behavior can be achieved, wherein the carrying capacity of a compliance element can be exactly matched to that of the adjacent channel profiles or lattice girders.
- the compliance element also begins to deform and absorb load.
- FIG. 1 a composite structure for a tunnel called.
- the illustration shows the composite structure 1 seen from the tunnel longitudinal axis in the direction of the mountains.
- the composite structure 1 comprises a curved construction 2 from end-to-end channel profiles 3, which are clamped together in the overlapping area 4 by clamping means 5 which are not illustrated in greater detail, so that the channel profiles 3 can slide relative to one another at a correspondingly high rock pressure.
- the composite construction 1 further comprises a concrete shell applied to the mountains by means of shotcrete or shotcrete in which the gutter profiles 3 are also embedded.
- each compliance element 8 In a recessed area 7 of the concrete shell 6 are located next to the channel profiles 3 compliance elements 8. As in this context, the FIGS. 3 and 4 can be seen closer, each compliance element 8, a lower support plate 9 and an upper support plate 10. On the underside 11 of the lower support plate 9 and the top 12 of the upper support plate 10 reinforcing elements 13 are welded in the form of U-shaped bent wires, which, like the FIG. 1 can recognize, in the concrete shell 6 protrude.
- the support plates 9, 10 are connected in non-illustrated manner with the channel profiles 3.
- tubular body 16 In the height range between the two support plates 9, 10 are two separating plates 14, 15. Between the support plates 9, 10 and the separating plates 14, 15 are tubular body 16 is welded with a circular cross-section. Thus, three layers L, L1 and L2 are formed with tubular bodies 16. At the Embodiment, all tubular body 16 have the same diameter D and the same wall thickness WD. However, it is also conceivable that the diameter D and / or the wall thickness WD of the tubular bodies 16 vary from position L, L1 to position L1, L2.
- yielding element 8 is also in the composite construction 1a of FIG. 2 used. This differs from the Verbundausbau 1 of FIG. 1 only in that instead of the gutter profiles 3 lattice girders 18 are used as a sheet expansion 2a. Thus, on a further description of the FIG. 2 waived.
- the hollow profile 17a according to the FIGS. 5 and 6 consist of a slotted tube.
- the slotted hollow section 17a is widened so that it fits for insertion into the tubular body 16 according to FIG. 5 must be compressed. In the compressed state, it can then in the tubular body 16 according to FIG. 5 be pushed in, so that it ultimately according to the representation of the FIG. 7 is applied by spring force to the inner wall 19 of the tubular body 16 and thus properly clamped in the tubular body 16.
- FIGS. 8 and 9 are used to fix the position of a circumferentially closed hollow section 17 in a tubular body 16 spring wires 20.
- two spring wires 20 are stapled punctually in opposite arrangement to the inner surface 21 of a hollow section 17.
- the insertion direction ER of the hollow section 17 forward ends 22 of the spring wires 20 protrude beyond the end face 23 of the hollow section 17 and are according to FIG. 9 Bent V-shaped.
- rear ends 24 of the spring wires 20 are bent by almost 90 ° to the outside.
- spring steel bands 27 are used for fixing a circumferentially closed hollow section 17 in a tubular body 16 .
- These opposing spring steel strips 27 are first bent over two layers and inserted when inserting a hollow section 17 in a tubular body 16 in the gap 28 between the hollow section 17 and the tubular body 16 with.
- the spring steel strips 27 brace due to their inherent spring force the hollow section 17 in the tubular body 16.
- the spring steel bands 27 may be fixed selectively before the insertion of the hollow section 17 in the tubular body 16 on the outer surface 29 of the hollow section 17.
