Definitions

  • the present invention relates to connecting stakes for beams and more specifically to connecting stakes of cylindrical shape which are inserted within the flange of a beam made of steel. More specifically, the present invention provides a connecting stake of cylindrical shape provided in the lower part with a fixing stirrup or predisposed nails capable of being inserted pneumatically within the flange of a steel beam for the purpose of strengthening the connection between the slab made of concrete which is above and the beams made of steel which are disposed beneath the slab.
  • the crux of the present invention resides in the fact that the connecting stake, being initially provided with a fixing stirrup with nails predisposed in the openings of the same stirrup, is mounted on the flange of the beam by means of a pneumatic riveting machine which inserts the nails in the flange of the structural section so that a perfect and stable fixing is achieved, both when the connecting stake is mounted directly on the flange of the beam as well as when it is mounted through the interposition of a plate in a fret shape which supports the casting of the concrete slab placed above it.
  • the connecting stake is constituted by a cylindrical rod (1) provided with a head of enlarged diameter (2) obtained by cold heading and also with a base plaque (3) of rectangular shape with two lateral borders (4) and (5) which rigidify the structure and which are obtained by bending in the cold the steel plate.
  • the fixing of the stake (1) to the base plate (3) is obtained by riveting the lower part of the stake (1) of reduced diameter so as to form a conical portion (6) which ends on the level of the bottom surface of the rod (3).
  • the latter is provided with two orifices (7) and (8) within which the nails (9) and (10) are inserted, the nails being advantageously coated with two thin cylindrical sheaths (11) and (12) which permit to maintain the nails (9) and (10) inserted in them in position for mounting or inserting during storage as well as during the transportation and when the fixing operation is carried out.
  • the fixing operation is obtained by means of a pneumatic nailing machine which acts on the heads of the nails (9) and (10) as shown in Fig. 4 so that the tips of the same nails penetrate within the flange (13) of the beam made of iron on which the stake (1) is intended to be fixed.
  • the object may also be achieved by means of the interposition of the fret shaped plate (14) shown in Fig. 5 when the latter is interposed between the connecting stake (1) and the upper flange of the beam (13).
