摘要
The utility model relates to the field of construction and is intended for invisible installation of structures. Invisible fasteners for facade and terrace boards is a plate made of steel. The fastener has one open hole for a self-tapping screw for the guide - lags for mounting the first board at one end. It contains a spacer in the form of a tongue bent at 90 ° from the edge of the plate, located along the longitudinal axis. In addition, the fasteners have at least one round hole and at least one oval-shaped hole located on the longitudinal axis, under the self-tapping screws for the board. Also, the fastener contains at least one hole for a self-tapping screw for the guide - lags from the opposite end of the open hole. At the same time, chamfers are made in the holes. In the loaded places of the fasteners, stiffeners are made in the form of bulge-extrusions. On the ends of the fasteners on both sides of the axis, notches are made in the form of semicircular cut holes, and chamfers are made on the narrow ends on both sides of the fastener. Fasteners allow for easy bending of fasteners in places of notches for easy planting of protruding fasteners under the board, which allows bending of fasteners against guides - logs, which is necessary for the beginning and end of installation of structures with an external framing box. 4 s.p. f-ly, 8 Fig.
