The bar system comprises bars and level adjustment members, the bars being formed with through holes extending transversely in relation to the lengthwise extension of the bars and at least adjacent the holes, with engagement parts. The level adjustment member is adapted for attachment in the bars so as to project in the shape of load-carrying legs from the bars against the support structure. It comprises hollow rods, the end face of which that in the attached position of the rods projects from the bar being provided with an opening for attachment of the rod to the support structure by means of a fastener and at the opposite end with external threads. The level adjustment member also comprise internally threaded sleeves (3, 21, 41) the threads of which match those of the rods (4), in that the sleeves (3, 21, 41) are manually applicable to the bars (1, 20, 40) by engagement with the engagement parts (10, 23, 42) of the bars. The rods (4) are attachable to the sleeves (3, 21, 41) by thread engagement as they are being screwed into the bar, during which operation also the length by which the rods (4) project from the bar (1, 20, 40) is adjustable. |
