Definitions

  • the present invention concerns a device and method for the production of horizontal flat structures, such as bearing floors, floors or others, which make up the cover and the support of the intermediate floors of buildings. Moreover the present invention also concerns a mobile supporting formwork, or board, on which the flat structure is cast on site, and a lifting equipment for said mobile formwork.
  • This type of known boards has the support frame adjustable in height, so as to determine the height of the cast from the floor and, once the cast is consolidated, they are transported above the bearing floor which has just been made, so that they are ready to make a new bearing floor of a higher floor.
  • This known lifting equipment supports and lifts the formwork from below and, by means of the action of the crane, transports the board itself to above the bearing floor.
  • Purpose of the present invention is to allow to produce bearing floors with the possibility of transporting the board from below to above the bearing floor itself, in a limited time, with operative simplicity and with limited risks for the operators, without incurring the disadvantages of the state of the art.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • the present invention refers to a device, to a formwork, to a lifting equipment and to an method, for the production of horizontal flat structures.
  • the present invention provides a formwork having a molding surface on which a cast of concrete is made on site, in order to define the horizontal flat structure, and a lifting equipment, able to be selectively constrained to the formwork, in order to lift the latter from a first position lower than the horizontal flat structure, to a second higher position resting on the horizontal flat structure.
  • the formwork comprises first constraint means disposed in proximity both to its molding surface and also to a barycentric zone of the formwork itself.
  • the lifting equipment is conformed in such a way as to define at least a lower segment provided with second constraint means able to cooperate with the first constraint means, in order to define the attachment from above of the lifting equipment to the formwork.
  • the equipment comprises at least an upper segment connected to the lower segment and provided with connecting means with which it is able to be connected in a balanced way to a lifting member.
  • the connecting means is disposed on the upper segment in such a way that, with respect to the conformation of the lifting equipment, the lifting action applied on this upper segment by the lifting member is substantially balanced, that is, sufficiently compensated, with respect to the action of downward traction applied by the weight of the formwork on the lower arm.
  • the attachment from above of the lifting equipment to the formwork allows to simplify and standardize the conformation of the lifting equipment, guaranteeing an efficient and rapid lifting of the formwork itself.
  • connection from above with respect to the first constraint means disposed in proximity to a barycentric zone of the formwork, allows a standardized lateral extraction of the formwork with respect to the bulk of the horizontal flat structure.
  • This lateral extraction of the formwork can be carried out in safety until the barycentric zone of the formwork is at a determined distance, irrespective of the length of the formwork, with respect to the lateral edge of the flat structure.
  • the lower segment of the lifting equipment can be partly inserted between the flat structure and the molding surface of the formwork, until reaching the first constraint means.
  • the entity of this insertion is directly proportionate to the distance of the barycentric zone from the edge of the structure.
  • the size of the lower segment can be standardized depending on the entity of the distance and not of the sizes of the formwork.
  • the device 10 substantially comprises a mobile formwork, or board 12, and a lifting equipment 13 which, assisted by a crane or other lifting device, selectively moves the board 12 between a first position lower than the bearing floor 11 and a second position resting above the bearing floor 11, in order to make a new bearing floor 11 of a higher story.
  • the board 12 comprises a lower support frame 15 and an upper molding surface 16, substantially flat, on which concrete is directly cast on site in order to make the bearing floor 11.
  • the support frame 15 comprises a pair of reticular beams 17 to support the molding surface 16, and a plurality of supporting legs 19, in this case eight, made telescopically to allow to regulate the board 12 in height.
  • the molding surface 16 comprises a plurality of openings 16a, re-closable, made in correspondence with each constraint pin 18, in such a way as to allow selective access from above to the latter.
  • the lifting equipment 13 comprises a frame 20 shaped like a double "C" and provided with two lower segments 21, two upper segments 22 substantially parallel to the two lower segments 21, and two connecting segments 23 which connect with each other one end of each lower segment 21 with respective ends of each upper segment 22.
  • Each lower segment 21 is advantageously shaped in a telescopic way, to be able to be selectively lengthened and shortened, and at the lower part comprises two constraint brackets 25 able to be inserted from above, through the openings 16a, to cooperate with the constraint pins 18.
  • the connecting ringbolts 26 allow to connect, through relative drawing cables 27, the lifting equipment 13 to a lifting crane, of the traditional type and not shown here.
  • Both the two lower segments 21 and the two upper segments 22 and the two connecting segments 23 are connected to each other by means of stiffening cross-pieces 29.
  • the method to make bearing floors 11 with the device 10 according to the present invention is as follows.
  • the board 12 is set up, regulating the supporting legs 19, in order to dispose the relative molding surface 16 substantially horizontal and at a desired height from the floor.
  • the molding surface 16 is slightly detached from the bearing floor 11 formed ( fig. 2 ).
  • the four central supporting legs 19 are then also lifted, and respective revolving wheels 31 are associated with each of these ( fig. 5 ).
  • the jacks are released ( fig. 6 ) in order to rest the board 12 on the ground by means of the wheels 31, and to define a space between the molding surface 16 and the bearing floor 11.
  • a safety catch 32 is disposed on the floor, and is advantageously, but not exclusively, applied when the above and subsequent operations are carried out at a certain height.
  • the board 12 is then thrust on the wheels 31 until it protrudes laterally with respect to the bearing floor 11 ( fig. 7 ).
  • the entity of the movement given to the board 12 is such as to take the barycentric zone of the latter into proximity with the outside edge of the bearing floor 11.
  • the movement is such as to take the barycentric zone of the board 12 to a determined standardized distance from the outside edge of the bearing floor 11.
  • the lifting equipment 14 is disposed with its lower segment 21 in the space between the bearing floor 11 and the molding surface 16, in such a position that the constraint brackets 25 are in correspondence with the constraint pins 18 ( fig. 8 ).
  • the openings 16a are opened to allow the coupling from above of the constraint brackets 25 and the relative constraint pins 18.
  • the board 12 is positioned on the upper surface of the bearing floor 11 which has been previously made ( figs. 10 and 11 ), in order to prepare it for making a new bearing floor 11.
  • the constraint brackets 25 are detached from the relative constraint pins 18, the openings 16a are re-closed and the lifting equipment 13 is discharged ( fig. 12 ).
  • the lifting equipment 13 can have a different shape than that of the double "C” as shown here, for example a “Z”, an upside down “T”, an “I”, or others which in any case guarantee, on the one hand, the insertion of the lower segment 21 in the space between the bearing floor 11 and the board 12 and, on the other hand, a sufficient compensation and balance of the forces exerted by the crane and the board 12 during the lifting.
