Definitions

  • the invention concerns a bumper rail of safety fences consisting of a web, which consists of one tubular part and one U-shaped beam part extended along the tubular part and has its U-legs directed towards the side of the tubular part.
  • a safety fence web of above mentioned type is earlier known from e.g. SE-B-454 522. Certain problems have arisen with this known web and one of the problems is the difficulty to galvanize it so that no ferrous corrosion will occur. Furthermore it is difficult to simplify the manufacturing process so that the welding work is small and is as simple as possible.
  • the invention according to this application solves these problems and moreover the web will be reinforced by that the flexural resistance will be increased when the web is erected as a safety fence. The attachment of the web to the road will also be more safe according to the invention.
  • the invention is specified in independent claim 1.
  • the dependents claims 2-4 specify preferred embodiments of the bumper rail.
  • Fig. 1 is thereby a cross section along the line B-B in fig. 2.
  • Fig. 2 is a view along the arrows A-A in fig. 1.
  • Fig. 3 is a cross section of a second embodiment of the web.
  • Fig. 4 is a modification of the second embodiment according to fig. 3.
  • the band steel is formed by the roller mill into the shape, which is shown in fig. 1. Before the band steel is inserted in the roller mill, cuts 1 are recessed so that shoulders 2 are formed as can be seen from fig. 2. The web is welded together at these shoulders. A gap is left open at the other side of the band steel, see point 3. Due to this shape the safety fence web can be enclosed by zinc completely over its both sides when being galvanized.
  • the attachment of the safety fence web to the road poles is performed similar to what is disclosed in SE-B-454 522. There is however one difference and that is that the safety fence web according to the invention will be deformed when the web is placed in the screw clamping joint of the road pole and the screw is tightened, whereby contact will be achieved between the point 3 and the inner side of the safety fence web. The square part of the web will be a little wedge shaped by this deformation. The result from this is that a greater force is needed to draw the web out of the screw clamping joint.
  • a modification of the safety fence web is shown in fig. 3. Also this web is formed in a roller mill. Thereafter holes 4 are drilled through the U-shaped part and pins 5 are inserted in these holes, the ends of the pins thereafter being welded to its belonging holes 4.
  • the channel beam may in cross section have a certain angle according to what is shown in fig. 4. The angle is denoted with ⁇ in fig. 4.
  • the web is performed with pins which are attached by welding, or by any other means, to the holes.
  • the object of the pins is to give the web such a strength that it will not be deformed too much when the web is attached in the screw clamping joint of the pole. This will also prevent that it collapses when being hit by a car.
  • the attachment to the road pole is thus accomplished according to what is disclosed in SE-B-454 522.
  • the safety fence web has the form according to fig. 4 the screw clamping joint of the road pole is formed with corresponding angles.
