ATTACHMENT FOR CONNECTION OF WOODEN ELEMENTS IN "STAR" Russian patent published in 2020 - IPC E04B1/32 E04B1/58 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used in spatial rod wooden frames of buildings and structures of dome shape for formation of connecting units in form of "star". Disclosed is attachment for connection of wooden elements in "star", comprising upper and lower covers, central cylindrical support element between them and a coupling bolt passing through the center to form a nodal joint of the wooden elements radially directed towards the center and fixed in the assembly between the covers, uniformly distributed in a circle, note here that cover plates have holes to receive coupling bolt. Novelty is that covers are made from metal sheet with concave shape and shaped ledges on convex surface side. Shaped projections are made in the form of U-shaped slots radially located with decreasing to the center height of ribs, open on the side of concave surface and intended for installation of wooden elements with pre-milled ends. At that U-shaped slots in covers correspond to sizes of cross-section of radially oriented wooden elements and are located opposite to each other, and their bases are parallel to each other and are inclined to axis of assembly. Besides, along the longitudinal axis of the base of the shaped ledge there are holes for cylindrical nails for attachment of covers and wooden elements, and the central cylindrical support element intended for installation on the bolt and fixation of the distance between the upper and lower covers is made in the form of a tube enveloping with the inner surface the central ledge in the upper cover, made during stamping and directed towards its concave surface.

EFFECT: technical result is to expand the range of technical means for reducing labor costs when mounting a nodal joint of wooden elements in a "star" due to structural improvement of the hinge joint and use of fasteners of complete factory readiness, characterized by simplicity of manufacture and assembly in nodal joint.
