    • Set of structural elements for producing supporting structures, having supporting bars 5 and cylindrical connecting elements 1 for insertion heads 6 provided on the end sides of the supporting bars 5, the connecting elements being provided with a plurality of slots which are open on one side and extend, parallel to one another and to the axis of the cylindrical connecting elements, from the surface to the center, and the slots each being widened, at a distance from the radial ends of the same, to form chambers for receiving the insertion heads. The insertion heads are formed in the flat end regions of the supporting bars, at a distance from the end edges, in that at least two parallel slits are provided at an angle of 90.degree. with respect to the end edge, and, in each case one bead running parallel to the end edge is formed in the strips produced by the slits, and the beads of adjacent strips are respectively formed on mutually opposite sides, with the result that an annular thickening with circular or oval cross section and an outer circumference which corresponds to the cross section of the chamber in the slots of the connecting elements is formed in the region of the flat ends of the supporting bars, parallel to the end side, beside a continuous border strip.
    • 一组用于制造支撑结构的结构元件,具有支撑杆5和设置在支撑杆5的端侧上的插入头6的圆柱形连接元件1,连接元件设置有多个在一侧开口的槽, 从表面到中心彼此平行并且相对于圆柱形连接元件的轴线延伸,并且每个狭槽在其距离其径向端部一定距离处被加宽,以形成容纳插入头的室。 插入头形成在支撑杆的平坦端部区域中,距离端部边缘一定距离处,因为至少两个平行狭缝相对于端部边缘以90°的角度设置,并且在每种情况下 在由狭缝制成的条带中形成平行于端缘的一个胎圈,并且相邻条带的胎圈分别形成在相互相对的两侧,结果是具有圆形或椭圆形横截面的环形增厚和外周 对应于连接元件的槽中的室的横截面形成在平行于端侧的支撑杆的平坦端的区域中,在连续的边界条旁边。
