Definitions

  • the present invention relates to a shuttering system for cast floors which is characterized in that it is fully recoverable.
  • one of the objectives for the reduction of costs in construction consists in the reduction of the investment in shuttering devices and members, since these represent an important part of the costs of the construction.
  • the invention set himself the aim of obtaining a shuttering system which is fully recoverable with regard to the actual floor cast shuttering members.
  • the present invention discloses a shuttering system for cast floors which can be designated as being fully recoverable, that is to say, at the moment when a specific strength of the cast floor is reached, all the members used for the actual shuttering of the cast floor, with the exception of some props, can be dismantled.
  • the entirety of specific shuttering members, including the entirety of the beams, both panel supporting beams and lower supporting beams, can be recovered for use in other areas of the construction.
  • the system of the present invention is fundamentally based on arranging recoverable members, having special characteristics, adjacent to some of the floor shuttering panels, for example, one every three or four shuttering panels, said recoverable members, which in a preferred solution may assume a tie-beam structure, being supported, in a manner that can be easily dismantled, at one of their ends by the support beams for the shuttering panels and at the other end, remaining facing one another and supported by an intermediate beam.
  • Said recoverable members have a variable width, preferably reduced, sufficient as a minimum for permitting the introduction and placing of the head or upper end of a building prop, and combine with the structure of the beams in such a way that they permit easy dismantling thereof at the moment of their recovery, for example, the support beams or panel supporting beams having a stepped lateral region slightly inclined at an angle, so that the recoverable members or tie-beams might be equipped with rebates or cavities on their inner lower edge in order to permit their downward rotation on a flat step.
  • the recoverable members are equipped, near each of their ends and on the lower face, with respective stops for their centring on the long sides of the panel supporting beams.
  • the system of the present invention therefore makes it possible, once sufficient hardening of the concrete floor has taken place, to proceed with the dismantling of an intermediate panel supportingbeam, which will in turn permit the dismantling of two recoverable members of the system, which will therefore provide a free surface of the lower face of the cast floor which will allow the arrangement of support props directly in contact with said lower face, permitting direct bearing of the cast floor on the props.
  • the floor shuttering panels and the support beams for same can be dismantled, so that the cast floor will remain supported only by several props, the entirety of the lower supporting beams, beams and shuttering panels, which are the actual floor shuttering members, having been recovered, as well as a large part of the props or stanchions.
  • Figure 1 shows in perspective an assembly of members for the shuttering of a cast floor, seen in perspective from above.
  • Figure 2 shows a perspective view of a part of the actual assembly of floor shuttering members from below, after the recoverable members of the invention have been dismantled.
  • Figures 3 to 8 are sectional views which show in a simplified manner the functioning of the system of the present invention in the shuttering of a cast floor from the placing of the recoverable members to their final dismantling and the support of the recently set floor by means of props.
  • Figures 9 and 10 show, respectively in side elevation and in plan, views of a recoverable tie-beam of the type used in the present invention.
  • Figure 11 shows a perspective view, from below, of a recoverable tie-beam used in the system of the invention.
  • Figures 12 and 13 show simplified sections of intermediate beams for the support of the recoverable members which in the first case combine with beams having inclined flanks and in the second case with beams equipped with flat steps.
  • Figures 14 to 19 show an alternative to the process of assembly or de-shuttering of the recoverable members in a similar manner to that shown in Figures 3 to 8, valid for the case where a version of said members such as those shown in Figure 13 is employed.
  • Figures 1 and 2 show the arrangement of a multiplicity of shuttering panels 1, 1', 1", supported on end beams, such as those indicated by the numbers 2 and 3. Underneath are arranged other intermediate beams, parallel to 2 and 3, indicated in the drawing by the number 4, and lower supporting beams, such as those indicated by the number 5, which are intended to support by their lower face the beams 2, 3 and 4.
  • the support on the floor 6 of the lower storey is effected by means of a multiplicity of props 7, 7', which bear on the floor 6 and which receive the load of the beams.
  • some recoverable members such as those indicated by the numbers 8 and 9, are arranged parallel to the shuttering panels 1, 1', 1", adjacent to one of said panels, grouped with a specific series of floor shuttering panels, which has been shown in the drawings by the numbers 1, 1', 1".
  • Said recoverable members 8 and 9 bear by one of their ends on the beams 2 and 3, and by the other ends which are facing one another, as can be seen in Figure 1, on one of the intermediate beams 4.
  • Figure 2 shows, from below, the arrangement of Figure 1, in which can be seen the shuttering panels 1' and 1" and also the intermediate beam 4, and various props on which said lower supporting beam and which are indicated by the numbers 10, 11 and 12.
  • the beam 3 supported by the props 14, 15 and 16 and which is the one which will bear the ends of the shuttering panels and the outer ends of the recoverable members 8 and 9.
  • the recoverable members such as 8 and 9, will be variable in shape, especially as regards width, their length being part of the length of the shuttering panels, for example 1', 1" between which they are situated. Their function is to permit prior dismantling which will free local areas of the lower face of the cast floor in order to allow the placing of props for direct support of said floor cast, permitting the dismantling of the entirety of the shuttering panels and also of the support beams, intermediate beams and their respective props.
  • the structure of said recoverable members will therefore be preferably extended with a width which will correspond, at minimum, to the width of the head of a prop so that the freed space will permit the placing of the prop, but without express limitation as regards the maximum value of the width, since the function of said intermediate devices could be performed by shuttering panels of lesser length than the main panels.
  • said recoverable members may assume a structure of tie-beams of sheet metal cut and bent as will be explained hereinafter.
  • Figure 5 shows the dismantling of the intermediate beam 4, the recoverable members 8 and 9 being able to be loosened afterwards on tilting on the inclined support steps of the beams 13 and 18.
  • the shuttering panel 20 obviously double the length of said members.
  • the recoverable members are characterized in that they have a length which will preferably be half that of a floor shuttering panel and a width which is variable although preferably reduced, which should fulfil the condition of permitting the direct bearing of the head of a prop, that is to say, its width should be greater than that of the top end of the support props that are being used.
  • a preferred construction is shown in Figures 9, 10 and 11, it being observed that a recoverable member 8 is constituted by a sheet metal member, for example of cold-rolled steel sheet conveniently cut and bent on its lateral edges and ends, forming a very flattened box structure, with lateral walls of the longer sides 23 and 24 and shorter sides 25 and 26.
  • the recoverable members 8 may be constituted by any method and materials compatible with the technical functions explained, that is to say, corresponding dimensionally to a narrow zone between shuttering panels and permitting their initial dismantling in order to be able to place props in direct contact with the at least partially hardened floor cast.
  • the beam 2' has a stepped shape similar to that of Figure 12, although its steps have faces 32 that are not inclined but substantially horizontal.
  • the bearing point of the beam 8' which is shown by the number 33 and which corresponds to the bearing point 34 of the case shown in Figure 12, is formed by the rib formed by the vertical face 35 of the recoverable member 8' and the corresponding lower face 36. In this way, a free zone 37 is formed between the lower face of the recoverable member 8' and the corresponding upper face 38 of the beam 2', in order to permit downward rotation of the recoverable member 8', the detailed functioning of which is shown in Figures 14 to 19.
  • the precise form of the cavity 37 may be widely variable in the shape of curvature or step in the opposite direction or any other arrangement which permits the partial free rotation of the recoverable member 8, 8' to permit its dismantling.
