Abstract (en)
In a structural node joint of the kind comprising a) a hollow connecting member (1), in the wall (2) of which a number of through-going attachment holes (3,4) are formed, b) the adjacent ends of a number of rod-shaped or tubular elements (5,6), c) a number of attachment screws (7,8), the heads (9) abut against the inside of the wall (2), and the shafts (10) of which extend outwardly through the attachment holes (3,4) and are screwed into said ends of the elements (4,6), and d) an access opening (11) formed in the wall (2) of the connecting member (1), said access opening (11) being sufficiently large to allow the introduction of the screws (7,8) and possibly associated washers (19) through the opening into the internal cavity of the connecting member (1), said access opening being closable by means of a releasably secured closure member (12), the features consist in e) that the access opening (11) is not substantially larger than what is necessary to allow the heads (9) of the screws (7,8) and possibly associated washers (19) to be introduced through it, and f) that a thread (14) is formed in the access opening (11). n
