FIELD: construction.

SUBSTANCE: invention is related to construction of wooden structures and may be used in construction of wooden decks, floors or fences. Method includes manufacturing of interlocking items, for which slots are arranged at end side of one of connected items in vertical plane with depth equal to thickness of interlocking device vertical wall. Then they are installed in slots aflush, and another item is joined by end to interlocking item, and thus all wooden items are connected serially one after another. Besides, each subsequent row of interlocking items is displaced relative to the previous one by half of pitch between them. Device for connection of wooden parts, which is made of metal, has vertical wall with height that is equal to thickness of connected items. Plates are fixed rigidly and coaxially to the wall perpendicularly on both sides, and are sharpened on one side with width of at least 1-2 thicknesses of joined items and length equal to width of joined items. Pitch of interlocking items installation makes at least 1.618 of their length, moreover, round openings are arranged for fastening elements on vertical wall of interlocking item.

EFFECT: higher strength of connection.
