摘要

The device has a leg placed near ends of a rafter (17), where the leg has an outer protrusion at its lower end, where the protrusion is in the form of a hollow hemispherical dome (9) cooperating with a hemispherical basin (15). The basin is integrated to a stable structure unit such as wall plate`s backside (16). The dome has pre-established perforations receiving a fixation screw before immobilization of the dome.
