Definitions
- the present invention relates to a stiffening element according to the preamble of independent claim 1.
- arch supports are installed to support the vault after tunneling, with which free passage is guaranteed and which are subsequently concreted in.
- shotcrete means that more and more lattice girders are used because, unlike I or U girders, they have no splash shadow and therefore an even concrete surface is made possible.
- lattice girders are described for example in EP-B-73733.
- the stiffening elements should ideally be relatively close to each other on the one hand, and on the other hand, the single girder bar of the lattice girder should be supported in the middle between the nodes, so that its buckling length is halved.
- the tried and tested pyramid shape of the stiffening element is intended to ensure a high level of dimensional stability or cross-sectional stability both against bending stresses and against beans stresses on kinks and torsion can be achieved.
- the stiffening element can be formed in one piece, so that its connection to the belt rods can take place at relatively few welding points, which results in a correspondingly lower embrittlement of the material due to the welding.
- the welding point S5 on the apex belt T3 is specified as the only welding point, although it could easily be addressed as two welding points if the two wire polygons 1, 2 were at a greater distance.
- a two areas marked by a dashed line are highlighted. In these areas A, in addition to the wire polygons 1, 2, a wire triangle 3 is welded on in order to increase the strength of the belt carrier.
- three welding points S1, S2, S3 or S6, S10, S11 etc. practically coincide so that the undesirable formation of martensite is promoted, which was mentioned earlier.
- two triangular wire polygons 10, 20 similar to the above-described example can also be seen in FIG. 2, which are welded to a common welding point S3 on the apex belt T3.
- the wire polygon 20 is provided with a strut 40 connecting the two base straps T1, T2
- another triangular wire polygon 30 is connected to the other wire polygon 10, but without a strut connecting the two base straps T1, T2.
- the necessary strut between the base belts T1, T2 is formed by the following wire polygon as indicated by a broken line.
