Definitions

  • the ceiling formwork support system that is the object of this invention comprises several elements that represent a novelty within its field of application, all of them conceived to provide greater stability to the system while facilitating its assembly and disassembly.
  • One of the elements of the system corresponds to a strap, consisting of a beam defined by a profile that comprises a flat lower surface so that it can be supported on the upper surface of one or more strap holders.
  • the present strap is characterized in that at least one end of the profile comprises a terminal, the base of which is defined by an inner corner contiguous to the profile and an outer corner longitudinally opposite the previous one, the outer corner having a descending extension configured as a point. support in a longitudinal groove of a belt holder.
  • the system comprises a slotted strap holder defined by a profile that comprises a flat upper surface, characterized in that it comprises at least one slot in the longitudinal direction on the upper surface, suitable for receiving the downward extension of the terminal of the previous strap.
  • This belt and slotted belt holder configuration offers an alternative to existing roof form support system that is inexpensive to manufacture, allowing operators to place the belt on the slotted belt holder from a lower level than the formwork, and that prevents inadvertent detachment of the straps once installed.
  • the strap it is the outer edge of the downward extension that is defined to be the fulcrum in the groove (or what is the same, it does not form a right angle, but an angle less than 90 ° ), so that the strap can be extracted by pivoting it downwards with respect to said external edge. Thanks to this configuration, the upper end of the belt does not rise when it is pivoted downwards, thereby preventing the displacement of the supported formwork.
  • the extension is of sufficient length to provide the necessary space to extract the belt from the slotted belt holder when it is pivoted downwards without the need to raise the supported formwork.
  • This length is therefore linked to the depth and width of the groove, as well as the distance of the groove to the lateral surface of the belt holder.
  • the length of the extension is such that, in its condition of bearing in said groove, the lower surface of the profile is at the same level as the upper surface of the strap holder, at the same time as the terminal has a slit on its lower face, transverse to the longitudinal direction of the profile and located between the inner corner and the outer corner, whose depth and width dimensions allow the necessary space to be able to remove the strap from the slotted strap holder without having to lifting the supported formwork.
  • the space is still provided to extract the strap from the slotted strap holder without raising the supported formwork, while allowing the strap to remain at the same height in the event that it is the bottom surface of the profile that it needs to be supported on the top surface of the slotted strap holder, and not the terminal, leaving a section of strap cantilevered.
  • the upper corner of the outer face of the terminal is rounded, so that removal of the strap is further facilitated without lifting the supported formwork.
  • the base of the terminal, or at least the support extension is wider than the base of the profile, with the intention of offering greater stability when supported by the slotted strap holder.
  • a preferred embodiment may comprise two longitudinal grooves on the entire upper surface, suitable to allow the reception of two belts aligned with each other, one on each side of the slotted belt holder.

  • Another element of the present system consists of a self-adjusting belt holder distance fixer, defined by a profile that comprises at least two lower slots destined to receive two parallel belt holders and whose distance is to be set, the slots being transverse to the longitudinal direction of the profile, being characterized in that the width of the grooves in their entry zone is greater than that of the belt holders, while it decreases as the groove enters the profile, to a width less than that of the belt holders.
  • this fixer allows to fix the distance between the belt holders (and therefore help to stabilize the formwork support system) without the need for precise positioning and without the need for the belt holders to be at a precise distance.
