The subject of the main patent application H 18615 VI / 5c is a longitudinal direction of an underground stretch effective bracing of the line extension., which from in; in this direction at intervals behind one another, Extension units, preferably composed of steel sections, and. from bracing columns i exists, which are arranged between these units in the longitudinal direction. According to the The proposal of the main patent application should end with the associated. Side faces of the Extension units full of adjoining supports, near each end a rigid one pointing to the section joint Wear approach and the approaches of two adjacent ones on either side of an expansion unit Supports by a bolt, preferably designed as a swivel hook, resistant to tension and compression, but releasably connected to one another: to be.

Claims (4)

In different places on the side surfaces! the webs of expansion units made of I-profile steels. 2, the bracing supports, which consist of U-shaped bent sheets 103 and are arranged horizontally in the longitudinal direction of the section, lie snugly with their ends 4. The lugs 105 and 106 of each post form one. Part of the plate 103 and are above or below one end of the associated swivel hook ?. Outside the area of these approaches, the sheet metal edges 103a are bent outwards and, when the sheet metal is in a horizontal position, form longitudinal strips protruding upwards or downwards. If a support 103 consists of two parts 103 b and 103 c, the adjacent ends of which contain the longitudinal slots are pushed into one another in an overlapping manner, as can be seen in FIGS. 2 and 4. The two sections can then be braced together by means of simple setting wedges 112 or the like driven into the slots. The L-shaped outwardly beaded sheet metal edges 103a ″ of the inner part 103 b overlap the outwardly bent edges 103 o of the outer part 103 c at the point of overlap. 1. Bracing for the expansion of underground routes according to patent application H18615VI / 5c, in which bracing supports arranged in the longitudinal direction of the route with their ends at the. associated side surfaces' of the expansion unit fit snugly, carry a rigid approach pointing to the section joint near each end, and the approaches of two adjacent supports lying on either side of an expansion unit, by a bolt preferably designed as a swivel hook, tensile and pressure-resistant, but are detachably connected to one another, characterized in that the stiffening supports consist of U-shaped bent and preferably horizontally arranged sheets (103) , the attachments (105 and 106) of which form part of the sheets. 2. Bracing according to claim 1, characterized in that the sheet metal edges (103a) of each support (103) outside the area of the lugs (105 and 106) are bent outwards. 3. Bracing according to claim 1 and 2, characterized in that, in the case of a multi-part design of the supports (103), their sections (103 t and 103 c). the junction with their. Ends are pushed into one another in an overlapping manner and at this point have longitudinal slots into which setting wedges (112) or the like are to be driven in order to clamp the sections together. 4. Bracing according to claim, characterized in that the sheet metal edges (103 d) of the section (103 b) lying on the inside at the point of overlap are flanged outwards in an L-shape and at this point the sheet metal edges (103a) of the outer section (103) which are bent outwards are at this point c) overlap.
