SELF-FIXING CONNECTING ELEMENTS FOR PANEL STRUCTURES AND METHODS OF THEIR PRODUCTION Russian patent published in 2017 - IPC F16B5/07 

FIELD: construction.

SUBSTANCE: invention relates to composite structures and aims at increasing reliability of connection. Method of making self-fixing connecting element in panel structure, including:provision of panel structure including two face sheets and core part, baffle between them to form multilayer structure; making in first part of panel structure slot holes with self-fixing end parts; making on second part of panel structure elongation in form of projection with flexible self-fixing elements, which contain envelope parts and parts for engagement, wherein between parts for engagement and end side of panel structure there are gaps; and mutual fixation of flexible self-fixing elements of elongation in form of a projection with self-fixing end parts of slotted hole to make self-fixing connecting element in panel structure. Step of making on second part of panel structure additionally involves making elongation in form of projection with converging sides to be fitted in said slot hole, size of which is greater than size of slot holes, so that flexible self-fixing elements are mutually locked with self-fixing end parts without possibility of extracting of elongation in form of ledge slot hole.

EFFECT: higher reliability.
