Road fence

 

(57) Abstract:

The invention relates to a device for the protection of roads. Road fence, containing the rack 1, the intermediate spacer element holder 2 located parallel to the ground, fastened one end to the rack and bearing at the other end of the enclosing panel N. the Element holder 2 has a vertical wall plate 102, part 502 which is a structural weakening in the form of either bumps or holes with base 1 by means of fixing bolts of 7.8. In the wall 102 may be made of the window to bend the spacer element up at impact. The holder 2 is fastened to the rack with brackets 602. The upper part of the bracket 602 is made with flanging deflected toward the supporting rack for supporting it. 8 C.p. f-crystals, 3 ill.

The invention relates to devices for road barriers with the supporting cast metal road safety panels that upon impact of the vehicle absorb the kinetic energy during deformation the displacement of the enclosing barrier fix it after absorbing the impact energy in a safe car position.

Known metal road safety is located parallel to the ground, pinned with one hand on this pedestal and bearing on the other side of the support piece, which is attached enclosing the panel, and the support piece is mounted on the specified intermediate element with the possibility of rotation about the hinge node charms parallel to the longitudinal direction, shock-absorbing end of the shock absorber, damping compensation reversal re-paving of the support piece around its pivot point suspension when hitting the car in the enclosing panel is proportional to the energy of the impact.

Known road fence, containing a rack, on which are fixed by means of the finger intermediate spacer element holder connected to one end of the enclosing panel /U.S. patent N 3981486, CL E 01 H F 15/00, 1976/.

The invention solves the problem by simplifying the design of road fencing above types by eliminating complex support part connecting the enclosing panel with the intermediate element is a strut.

In Fig. 1 shows a General view of the enclosing panel with an intermediate spacer element holder; Fig. 2 structural weakening in the form of a corrugation of Fig. 3 structural weakening in the form of holes.

the other plate wall 102 of the element holder 2 in the place of attachment to the panel has a bracket 202 with diverging flat pads and holes or slots 3 days of the mounting panel, the bracket 202 has A bevel around 2-4owith respect to the vertical, thereby enclosing the panel will be slightly tilted toward the road.

The top and bottom of the intermediate element holder 2 has a-shaped longitudinal ribs 302 and 402, and the lower end of the ribs 402 from the side of the bracket is shifted backward relative to the single-shift of the upper end of the ribs 302. Part 502 of the vertical wall 102 has a triangular shape with a broadening bottom. In part 502 can be made holes 4 or corrugations 5, the latter can be a fan so that when the collision with the vehicle on the fence a specified part 502 jammed in the side of the supporting rack 1 with offset, increasing from top to bottom that will allow the bracket 202 and the panel to turn around a geometrical axis parallel to the axis of this panel, passing near the upper edge 302.

The wall 102 of the intermediate spacer element holder 2 in the zone part 502 to mount to the rack 1 can have the window 6, which if necessary can be made with ribs /tides/ stiffness 106, protruding to the side that faces to the rack 1. Box 6, having a rectangular or trapezoidal shape, serves as an additional element of the second bending the clip up with a turn around the corners of the window 6, i.e. close to the supporting rack 1.

The wall 102 is attached to the stand 1 by means of two bolts or other fastening means 7 and 8, which are located one above the other with an appropriate distance. Before the top of the fastening bolts 8 zone panel N wall 102 has a few holes or weakening of the cutouts 9, located on the arc of a circle whose center is on the lower bolt 7. Such a node intermediate fastening element on the rack in case of impact and deformation amortizatory forms an additional energopostachalna and energy dissipating system, because in this case, the element holder tends to turn up around the lower bolt 7, simultaneously deformed in part, weakened by the holes 9. Such a turn would be accompanied by the predictable care up fencing panels, which thus can effectively slow down nathusii her car, not allowing him to move through the fence.

The element holder 2 may be attached to opposite sides of the rack with one or two CasinoClub brackets 602, which are a continuation of the wall 102, and the internal solitaire is partially or completely from Miami, the top of these holes are used for fastening the gusset plates with stand 1, for example, by means of bolts 11. With a very strong blow to the fence perforated portion of the gusset plates having apertures 10 and 11, will serve as an additional strain-energy absorbing damping design, triggered at the final stage of shock when turning the offset of this intermediate element up to its full ocalenia from the holding rack 1.

For proper installation of the element holder 2 in the rack 1 kerchiefs 602 are top flanging 702, which are bent towards each other and when installing the holder rest on the upper horizontal surface of the rack.

On the wall 102 also made foot 802 with a slot 12 for the fastening bar 13, available from the rear side fixing all holders 2 on which is mounted the enclosing panel N.
