FIELD: construction.
SUBSTANCE: metal support for scaffolding, raised floor, stairs or a similar space bearing frame comprises a fastening facility to fix at least one railing fitting, preferably, a railing bar. The fastening device comprises a holder for a railing fitting, at the same time the holder is fixed permanently on the support, at the same time the holder has an adjacent element stretching from it in the first direction across the longitudinal axis with a horizontal coupling surface in the position of the support usage for a vertical support of the railing fitting, at the same time the fastening device additionally comprises a locking element rigidly connected to a support and arranged in the form of a locking lever rotated around the rotary axis to lock with geometric closure, preferably, without clamping forces, the railing fitting against its vertical removal upwards in the position of support usage in the locking position, at the same time the locking lever is fixed with the help of a fastening facility comprising a rotary axis on a support as capable of rotation around the rotary axis from the unlocked position downwards into the locked position and vice versa, at the same time the locking surface of the locking element in the locking position lies oppositely to the coupling surface of the adjacent element, and in the locking position, and also in the position of support usage is arranged at the distance along the vertical line above the coupling surface of the adjacent element, besides, the rotary axis in the position of support usage is located at the distance along the vertical line above the locking surface in the locking position. The holder is made in the form of a bracket stretching in the direction of a longitudinal axis of the support, which has or accordingly limits a closed or accordingly surrounded along the entire or substantially entire perimetre through hole to insert one end of the specified at least one railing fitting and to receive the adjacent part of the railing fitting, at the same time the through hole is limited with the help of a support element of the holder stretching at the distance in the transverse direction from the support, connected with the adjacent element for a side support of the adjacent part of the railing fitting, and in the position of support usage is arranged in the form of a vertical receiving slot stretching in direction of the longitudinal axis of the support. The following are also described: a connection system for a railing fitting and methods to fix a railing fitting.
EFFECT: higher stability of a frame, reduced installation costs, higher speed and simplified assembly and disassembly.
