  • An example of this kind is illustrated in FIGS. 23 and 24.
  • the crane 1 is here adapted to run by means of wheels 44 on rails 45, which are disposed in the well 16 between the longitudinal walls 17.
  • the lifting of the shuttering 20 27, the insertion and laying of the prefabricated floor slabs 36 and the lowering of the shuttering 20 27 on to the floor slabs 36 are in this case carried out sector by sector, while the shuttering panels 27 for the longitudinal walls 17 are preferably divided into a plurality of corresponding length sectors.
  • the travelling crane 1 is firstbrought into the region of one end of the well, where it lifts the corresponding shuttering panels 23, 24, together with the shuttering wings 25 articulated on them, and also the shuttering panel 26 and the respective portion of the shuttering panel 27. After insertion of the prefabricated floor slabs 36 under the raised shuttering, the latter is lowered and the crane 1 is run into the middle region of the well, where it raises the shuttering panel 20 together with the shuttering wings 25 articulated thereto and the respective portion of the shuttering panel 27 and inserts the prefabricated floor slab 36 under this shuttering and so on.
  • the travelling crane 1 shown in FIG. 23 and 24 is also preferably provided with an elevating device, for example one of the kind previously described.
  • the bottom bearing catches 41 of this elevating device are however here not disposed on the masts 2, but on the tops of sleepers 46 fastened to the rails 45, as can be seen particularly in FIG. 24..
  • the rails 45 are temporarily fastened to the masts 2 by a fastening device 47 and consequently are raised together with the masts and with the sleepers 46.
  • the fastening device 47 is released and the crane 1 can travel on the rails 45.
  • a single crane in the form of a rotary crane provided with a climbing device may be disposed in a central well, this crane effecting the raising of the shuttering, the laying of the floor slabs, and the lowering of the shuttering approximately sector by sector.
  • the reinforced concrete frame of the building need not necessarily consist of longitudinal and transverse walls 17, 18, 118 disposed roughly in U-shape, although this arrangement has particularly great stability which is especially advantageous when elevatable cranes are used.
  • Some possible groundplan forms for the reinforced concrete frame are shown in P16. 25. From this Figure it can be seen that in addition to the longitudinal and transverse walls 17, 18, 118 in continuous U-form the building frame may also consist of simple walls 48 or of posts 49, preferably of angular cross-section, or of hollow pillars 49 with an open or closed cross-section.
  • a method of forming floors and walls of successive stories using a reusable form having a vertical height equal to the full height of a storey including the steps of erecting the form in place by retaining the form in a suspended condition and securing the form in place, forming vertical walls by pouring the material of the vertical walls into the erected form, raising the form by a dis tance equal to at least one storey plus the thickness of a prefabricated floor siab following the curing of said vertical walls, and, with the aid of a crane erected in a well formed by internal vertical walls not covered by the floor slabs;
  • a method of forming floors and walls of successive stories using a reusable form having a vertical height equal to the full height of a storey including the steps of: erecting the form in place by retaining the form in a suspended condition and securing the form in place, forming vertical walls by pouring the material of the vertical walls into the erected form, raising the form by a distance equal to at least one full storey plus the thickness of a prefabricated floor slab following curing of the said vertical walls, inserting said prefabricated floor slabs horizontally between the raised form and the tops of the vertical walls and laying the slabs on the tops of the vertical walls of said one storey to form a floor, and lowering the form onto the floor and securing the form in place preparatory to the formation of the walls of the next higher storey.
  • the method includes raising the crane stepwise by at least one storey at a time and then supporting the crane by previously erected walls or floors.
  • step of forming vertical frame parts storey by storey comprises forming walls with an angular horizontal
