COMPONENT WOODEN PLUG AND METHOD OF FASTENING WOODEN AND/OR FIBROUS ITEMS Russian patent published in 2008 - IPC F16B13/04 F16B5/00 

FIELD: construction, equipment.

SUBSTANCE: invention relates to construction and connection mechanisms used in construction. The component wooden plug consists of a spacer assembly, which consists of head and shaft, clamp plate, designed for mounting on the outer side of the joined item, which is fixed to the fundamental item, second clamp plate, designed for mounting between the joined item and the fundamental item. Both clamp plates have mounting bores and a star shape dispersing from the outer circumference of the clamp plates and incurved pointed elements in the form of incurved needles of different forms. Curves of the needles alternate in opposite directions. The technique for fastening wooden and/or fibrous items uses wooden lugs, clamp plates which have mounting bores, combined with previously drilled openings in the joined items. The clamp plates are mounted in cavities which are made around the openings. On the upper and lower sides of the joined item there are cavities. On the upper side of the fundamental item there is a cavity, identical to the cavity on the lower side of the joined item. The cavity on the upper side pass through the joined item, and on the lower side which is the basic, there is a blind hole. The spacer assembly is inserted through the mounting bore of clamp the plates and openings in the joined item. As a result, there is formation of a multilayer construction with formation, internally and externally, of a uniform strong frame, without any internal stress.

EFFECT: increased strength properties of the multi channel construction, due to formation of a frame which does not have any internal stress.
