  • a method for assembling the mobile safety barrier according to the invention is characterised in that at places where panels are connected, bottom strips forming the bases of the mobile safety barrier and supporting the panels in the regions of their bottom ends are positioned, whereby each bottom strip comprises one concave and opened at the top strip profile with arms oriented upwards, and which has permanent connecting elements fixed to the strip profile, going through holes of bottom flat bars or panel profiles, and mobile connecting elements, forming together with the permanent connecting elements bottom elements intended for connecting the adjoining panels with each other at the bottom, and which at the bottom is inseparably fixed to a flat bar, and that upon putting the panels with their holes onto the permanent connecting elements embraces with its arms the bottom flat bars or profiles with holes in the regions of the ends of the panels that are being connected, and which are arranged as the permanent connecting elements, and then in concave beds opened at the top and the arms oriented upwards and formed in the regions of the ends of the adjoining panels in their top parts is positioned at the top the connecting element which is the flat bar or profile and which connect
  • the basic idea of the invention is to provide the mobile safety barrier comprising the panels, which is stiffened at the connection places at the bottom by one profile with the flat bar, and at the top it is stiffened by one connecting element, which has the holes arranged as the screws fixed to the concave beds opened at the top, which simplifies connecting the panels with each other, each of which can be removed from a row of panels by an upward movement upon unscrewing the nuts creating the connecting means together with the screws assigned to them.
  • An increase in barrier strength and stiffness is furthermore obtained due to a fact that a fit between the connecting elements and the concave beds at the top and a fit of the bottom flat bars or profiles in the open profile at the top of the bottom strip are the slide fits, therefore there is no clearance between the connecting elements and the concave beds, and between the bottom flat bars or the profiles and the profile arms of the bottom strip, in particular when the profile of the bottom strip with the arms oriented upwards is a channel section or a profile with a cross-section with a shape chosen from a fragment of trapezium, rectangular, circle or ellipse.

  • the holes of the connecting element have internal centring surfaces at the top, and the nuts tightened on the screws fixed permanently to the beds have external centring surfaces at the bottom, which are in contact with the internal centring surfaces, which enables an accurately positioning the adjoining panels each other, whereas a diameter of the internal centring surfaces increases upwards and a diameter of the external centring surfaces decreases downwards.

  • the bottom strip that is one channel section with the permanent connecting elements and the flat bar fixed to it at the bottom which may be shorter than the strip profile, with a length equal to a length of the strip profile, or longer than the strip profile, is cheap and simple to perform.
  • the connection of the panels with each other is not complicated, because while connecting it is sufficient to put the end of the connected panel onto the bottom strip and screw the nuts onto the permanent connecting elements in order to obtain a preliminary connection of two adjoining panels of the barrier with each other.
  • the concave strip profile opened at the top and forming the bottom strip with the arms oriented upwards is the profile with the cross-section in a shape chosen from a fragment of a trapezium, rectangular, circle or ellipse.
  • the connecting element with holes under the permanent connecting elements can be the profile with the cross-section with a shape of a rectangular, which is embedded in the concave beds, or it can be the flat bar or the profile with the cross-section in a shape of a trapezium, circle or ellipse.
