PCT No. PCT/SE83/00238 Sec. 371 Date Feb. 21, 1984 Sec. 102(e) Date Feb. 21, 1984 PCT Filed Jun. 9, 1983 PCT Pub. No. WO84/00288 PCT Pub. Date Feb. 2, 1984.The disclosure relates to shelving structures and other structures which, for reasons of stability, require reliable stiffening diagonally in one or more planes, by means of two mutually intersecting wire-like or rod-like stays (3, 4), the ends (5) of which are attached to the structure at four attachment locations (7). The erectness of the structure, for example on an uneven foundation, and the extent to which it can sway are both dependent upon the stays being brought to the correct length and tension between respective attachment locations. This has previously either been neglected or achieved with the aid of robust, expensive and complicated tensioning mechanisms, primarily tensionscrews, used to shorten the stays. A much simpler solution is afforded by the disclosure, according to which the point of intersection of the stays (3, 4) is displaced in the respective transverse directions of the stays (3, 4), while at the same time holding the structure fixed in its intended position, until the stays (3, 4) have both been tensioned to the same, desired extent, in which position the stays are connected together, either detachably or permanently, at said point of intersection by means of a suitable joint means (8, 9, 10), for example a spot weld or a screw joint. When a screw joint (8, 9, 10) is used, the joint can be tightened from the front of a shelving structure (1, 2) placed against a wall.
