FIELD: construction. ^ SUBSTANCE: assembly system comprises connection facilities to join facing boards arranged in one plane with each other. Connection facilities are formed by curvilinear sections arranged in the form of grooves located on a reverse side of at least some facing boards reaching side edges of facing boards and meeting each other on specified edges. As facing boards are installed nearby, oppositely to each other and in the point, where facing board corners meet, these curvilinear channelled sections form a channel on the reverse side of facing boards, where, at least on a separate section, insert elements enter tightly, joining and engaging at least two neighbouring facing boards. ^ EFFECT: easier process of assembly and provision of resistance and fixation of facing boards. ^ 31 cl, 29 dwg |
