Abstract

851,380. Roofs; building blocks. LUBBERT, E., SCHULZ, E., FINSTERWALDER, U., JECHT, R., and RUF, E. Dec. 2, 1957 [Dec. 1, 1956], No. 37418/57. Classes 20(4) and 87(1) A pre-stressed concrete roof is formed by supporting reinforced concrete slabs 4 on cables or like tensior members 3 suspended from and extending between supports 2, 7, 8 (Fig 1), filling joints between slabs witt mortar after all the slabs have beer positioned, allowing the mortar tc harden to produce a rigid roof unit and then pre-stressing the concrete by tensioning the cables. The roof is as sembled by laying the slabs at the low est point and continuing uniformly or both sides, the slope at right angles tc the cables being adjusted by suitable tensioning of cables 3. In one embodiment, Fig. 3, the slabs 4 have reinforcing members 5 which project as hooks for engaging over the cables 3 which are enclosed in sheaths 9. The joints are filled with mortar 6; when this has set the cables are further tensioned to pre-stress the roof, and the cavities of sheathing tubes 9 are then filled with mortar under pressure. In another embodiment, Fig. 7, the slabs have projections or tongues 15 with grooves 16 for seating on cables 3 to which they are secured by bent reinforcing members 14. Hairpin loops 26 of reinforcement projecting from adjacent slabs are bound together by wires 12, and stirrups 10 are engaged around adjacent cables 3 and slab reinforcements 13. The slab ends at right angles to members 3 have quadrant shaped recesses filled with concrete and containing tensioning members.
