Door frames can be attached to a vertical rack profile frame walls without additional stiffeners under the following conditions: ceiling height does not exceed 2.6 m, width of door leaf – 0.9 m, leaf weight – 25 kg. Rigidity of partitions to doorway in this case will be provided with a reliable connection rack and guide profiles, which, in turn, must be attached to an overlap of dowels near the opening (at a distance of 10 cm from it). Over doorway rack sections should be isolated bolt, increasing the rigidity of the assembly the door frame. If the weight of door panels is greater than 25 kg, the rack frame walls that flank the doorway, it is necessary strengthened. In practice, this amplification is carried out either by pressing in the rack wooden beam and then attaching it with screws, screws, or by installing an additional profile. Last manipulation of the door opening – setting him over the intermediate supports. They are usually mounted two. Electrical wires are passed through the inserts isolated holes in the walls rack profiles perpendicular to them.
Once again: no allowed cabling inside the rack along the profiles of the frame, to avoid damaging the screws when installing plasterboard. Built-in sockets firmly stick to the lining due to the interaction region of sockets and internal uncovered metal legs. Previously fixed in the partition wall outlet, and then mount the switch or plug input. Now you can on one side of the finished frame to establish and strengthen plasterboard.
