  • This capability is also indicated in Fig.
  • the above capability may be facilitated by the fact that the first joint pin 31 and the second joint pin 32 are arranged relative to the beams 1, 1' such that the portions of the pins 31, 32 protruding from the beams 1, 1' when the pins 31, 32 are inserted into the corresponding openings are not located in the extension in the groove 42.
  • the heads of the pins 31, 32 - i.e. the portions of the pins intended to protrude from the beams 1, 1' are relatively flat.
  • the scaffolding system further comprises a deck panel 50, the deck panel 50 comprising a deck panel connection member 52 adapted to be connected to at least one of the first and second beams 1, 1'.
  • connection accomplished by the male connection member and the female connection member of the beam 1 enables the groove 42 to extend uninterrupted over the connection between a first beam 1 and a second beam 1'.
  • the groove 42 may extend over a connection tongue 18 of the male connection member 12 at the first longitudinal end 10 of the beam 1.
  • the groove 42 extends towards the female connection member 22.
  • the groove 42 thus extends continuously over the beam 1, such that, when a first beam 1 and a second beam 1' are interconnected, their respective grooves 42, 42' may extend uninterrupted over the connection of the beams 1, 1'.
  • the uninterrupted groove 42, 42' enables uninterrupted attachment of further scaffolding devices to the beam assembly 100, for example, a deck panel 50 may extend uninterrupted over the connection of two beams 1, 1'.
  • the relative dimensions of the beam may be adapted to various needs.
  • the shape of the male connection member and the female connection member may be varied.
  • the number and/or shape of the connection elements, such as connection member tongues, may be varied.
