In a method and a device for anchoring timber framing (3, 4) movably to a substructure, e.g. in supplementary insulation of roofs or walls, timbers are laid out to cross over each other on the substructure in its entirety. Holes (7 or 8) are then made in the substructure at each crossing of the timbers as fastening devices (2, 10 or 20, 10) are anchored in the substructure. The holes may be through holes or they may bottom in the substructure, and they have an area which is greater than the arm (9 or 20) associated with the fastening device and which is to be inserted in the hole. Clamping is done by the holding means of the fastening device being engaged with the substructure and the bracket (10) of the fastening device gripping round the framing and urging it towards the substructure. The holes are then filled, suitably with a porous moisture-sealing material. The anchorage of the timber framing will be movable so that sheeting with larger surface than up to now can be erected without risk of damage or other undesirable effects. |
