FIELD: construction. ^ SUBSTANCE: mounting/assembly element comprises a bushing rivet, which has the first end having a deformable area designed for insertion into matched openings of items, and the second end, in which a traction rod is installed, the first end of which has a head with a diametre exceeding the diametre of the traction rod, and a break area arranged above the specified head in the deformed area of the bushing rivet, and the second end stretches to the top above the second end of the rivet with external thread, where a nut is screwed. The mounting/assembly element is designed for fixation with the help of a tightening tool interacting with the traction rod prior to its break in the break area. The second end of the rivet has a non-cylindrical internal transverse section. When the mounting/assembly element is in a tightly fixed condition, a part of the break zone connected with the traction rod head is arranged in the first end of the bushing rivet, or when the mounting/assembly element is in a tightly fixed condition, the break area is arranged in the lower half of the second end of the rivet facing the traction rod head. ^ EFFECT: more reliable connection of elements. ^ 10 cl, 12 dwg |
