Definitions

  • This invention concerns the construction of a profile in metal or in another material for the formation of trestles to be used to make joists in cement brick, concrete or another material, either manufactured in the factory, prefabricated or made and cast during work for use in the building trade for the construction of floors, decking, or other structures, the relative constructional and applicational system.
  • the prior-art joists that are generally used in building have the shape of an equilateral or isosceles triangle and the most commonly used are those in cement brick.
  • the aim of this invention is to provide an element that ensures that the reinforcing irons are positioned in their optimal position both during the assembly phase, the casting phase, the vibration phase and the seasoning phase.
  • the invention also enables other aims to be achieved, namely:
  • this result is achieved by simple conformation of the invention, inasmuch as from the opposing union of two profiles and from the installation of the reinforcing irons both the trestle that is resistant to cutting and locking in the appropriate seat of the reinforcing irons are achieved.
  • a joist has to be made wherein a reinforced section of more than 1000 cm2 is required a iron with a 12 mm diameter with a circumference of 37.704 mm or two irons with a 8 mm diameter with a circumference of 25.136 mm can be used that together amount to 50.272 mm.
  • the trestles that are used in prior-art joists consist of three longitudinal irons placed at the top of an upturned 'V' that are connected together by V-shaped brackets by means of welding or another prior-art technique according to custom whereas the reinforcing irons rest in the chamber of the base, where the trestle formed as above is also inserted.
  • the profile that is the subject of the invention consists of a wire that is suitably bent in order to obtain a series of upturned V-shaped profiles with different dimensions and functions that are nevertheless connected together.
