Description

The proposed utility model relates to road barriers and can be used to fence the carriageway of roads.

A patent of the Russian Federation for utility model No. 71123, IPC E01F 15/04, “Road barrier fence” is known. The utility model relates to road barriers for roads. The guardrail contains at least one longitudinal beam fixed to the uprights, while the uprights are oriented at an angle to the vertical, obliquely to the side of the beam, made solid and straight, so that the submerged part in the road base is a continuation of its above-ground part.

The disadvantage of this device is that when the vehicle hits the beam does not separate from the rack, one hundred leads to the deformation of a large section of the road fence, and therefore high repair costs.

Closest to the claimed utility model is the RF patent for utility model No. 79574, IPC E01F 9/00; E01F 15/04, “Barrier fence for highways”. A road barrier comprising vertical struts and longitudinal sinusoidal beams mounted along the road attached to them, secured to the struts via shock absorbing consoles, and sections of the longitudinal beams of the tier are lapped in series with each other along the lap along the path of the carriage, while the barrier fencing is provided with box beams moreover, the box-shaped beams are parallel to the beams of the sinusoidal profile and are fixed to the vertical posts in their upper side part with exceeded em top box girder above the end of the vertical upright, wherein the sinusoidal profile beams attached to two bolts each formed in cross-section U-shaped brackets, shock absorbers, said free ends of the shelves are oriented in the direction of movement of motor vehicles.

The disadvantage of this technical solution is that in its design beams of different sections are used, which makes this fence inconvenient for repair, as well as the large weight of the entire set of road fencing, which reduces safety.

The objective of the proposed utility model is to create the safest barrier for roads.

The problem is solved due to the fact that the barrier fence for roads contains two tiers of longitudinal beams of a sinusoidal profile, where in the first tier the longitudinal beams of the sinusoidal profile are attached through the shock absorbers, and in the second tier the longitudinal beams of the sinusoidal profile are connected directly to the vertical racks. The sections of the longitudinal beams are successively lapped together in the direction of travel of the vehicle. The beams of the sinusoidal profile of the first tier are bolted to each of the cross-sections made by U-shaped shock absorbers, and the shock absorbers themselves are oriented with their free ends in the direction of movement of road vehicles. Vertical posts are fixed in the ground by deepening. The longitudinal beams of the sinusoidal profile of both tiers are additionally equipped with a mounting stiffness plate, and the height of the U-shaped cantilevers of the shock absorbers of the first tier is equal to the width of the longitudinal beams of the sinusoidal profile. The uprights are additionally equipped with two identical tiers of longitudinal beams of a sinusoidal profile on the opposite side.

The road barrier 1 for roads contains two tiers of longitudinal beams of a sinusoidal profile 2, where in the first tier 3 longitudinal beams of a sinusoidal profile are attached to the uprights 4 through cantilever shock absorbers 5, and in the second tier 6 the longitudinal beams of a sinusoidal profile 2 are connected directly to the vertical racks 4. (see Fig. 2, 4, 5, 6, 8)

The sections of the longitudinal beams 2 are sequentially interconnected by an overlap in the direction of the vehicle. The beams of the sinusoidal profile 2 of the first tier 3 are bolted 7 to each of the cross-sections U-shaped shock absorbers 5, and the console-shock absorbers 5 are oriented with their free ends 8 in the direction of movement of the road transport (see Figs. 1, 3, 7)

The vertical struts 4 are fixed in the concrete base 9 by means of a recess 10. The longitudinal beams of the sinusoidal profile 2 of both tiers 3, 6 are additionally equipped with a stiffening plate 11, and the height of the U-shaped shock absorbers 5 of the first tier 3 is equal to the width of the longitudinal beams of the sinusoidal profile 2. (cm Fig. 2, 3, 4, 5, 7, 8)

The vertical struts 4 are additionally equipped with two identical tiers 3, 6 of the longitudinal beams of the sinusoidal profile 2 from the opposite side 12.

When installing the barrier fence 1 on the roadway of the bridge structure, the vertical struts 4 are fixed on a concrete base with 9 L-shaped cross-section brackets 13, which strengthen the structure of the fence on the bridge structure and greatly facilitate the repair of the damaged section (see Fig. 6)

The device is assembled as follows:

1. On a pre-marked for installation area install vertical racks. Vertical racks are installed at a calculated distance from each other.

2. Next, prepare the U-shaped console-shock absorbers of the first tier, tightly fixing them to the vertical struts by means of a bolted connection.

3. After that, the longitudinal beams of the sinusoidal profile of the first tier are fixed to the shock absorbing consoles by means of a bolted connection.

4. Next, the longitudinal beams of the sinusoidal profile of the second tier are fixed directly to the vertical posts by means of a bolted connection.

The device operates as follows:

1. Road barrier fencing set with longitudinal beams inside the roadway.

2. At the time of the vehicle’s collision with the road barrier, the vertical post deviates in the opposite direction from the vehicle.

3. The longitudinal beam of the first tier works to hold the passenger vehicle.

4. The longitudinal beam of the second tier works to hold the cargo vehicle or bus.

Service:

The damaged section of the road barrier must be replaced. At the same time, the replacement of the damaged area takes place locally and does not affect the operation of the entire road barrier. Replacing the damaged area is also facilitated by the use of beams and profiles of the same cross section.

Moreover, in the case of installing a barrier fence on the roadway of the bridge structure, the uprights are fixed on a concrete base with L-shaped cross-section brackets that reinforce the fence structure on the bridge structure and greatly facilitate the repair of the damaged area.

Advantages over prototype:

1. Ease of assembly of the barrier fence.

2. Efficiency at collision of both a passenger car, and freight transport or bus due to the presence of two tiers of longitudinal beams of a sinusoidal profile.

3. Safety for people in both a passenger car and a truck and a bus by reducing the ground clearance of the first tier to 394 mm, which eliminates the diving effect.

4. Manufacturability and simplicity in production and repair due to the use of beams of a single section, namely in vertical racks there are no additional elements of another section, in both tiers of longitudinal beams of a sinusoidal profile use the identical profile of a double sinusoid in cross section.

All of the above indicates the fulfillment of the technical task and the industrial applicability of the claimed device.
