ABSTRACT:
A connecting stake with a fixing stirrup and nails to be pneumatically inserted for connection with a concrete casting on an iron beam, comprises a staff (1) of cylindrical section and predetermined length, provided with an upper head (2) of a greater diameter, and with a lower bar of slightly lesser diameter. The lower bar has an end. The stake (1) has a shaped plaque (3) provided with two lateral openings (7) and (8), the plaque having a central opening, the end of the bar being riveted in the central opening. The nails (9) and (10) are predisposed in the lateral openings and are held within the openings by two thin sheaths (11) and (12). The concrete casting has an upper flange and the nails are inserted in the upper flange by means of a pneumatic nailing machine. The concrete casting is subsequently applied on the upper flange. The plaque (3) is provided with lateral wings (4) and (5) emerging from the plaque, whereby said stake is reinforced.
