Description

The utility model relates to road fencing and can be used in the arrangement of roads and artificial structures as barrier fences, which serve to increase the safety of road traffic on difficult road sections and protect it from critical damage.

A retention barrier for roads is known (patent RU2278199, publ.: 06/20/2006) containing vertical posts and longitudinal beams attached along them along the road, characterized in that the posts are made of a curved profile of a U-shaped cross-section, or of two connected between bent profiles of a U-shaped section, or from a profile of a C-shaped section, and the longitudinal beams are made of a profile in the form of a C-shaped section with additional shelves bent inward to the section, and the longitudinal beams are attached to the racks in one or more tiers directly or through shock absorbers using a fastener in the form of a mounting bracket, which is a bolt with a U-shaped washer welded to its head, made in such a way that the bolt passes through the through longitudinal groove of the beam, and the washer covers the sections bent inward shelves, ensuring the installation of vertical racks with any step, and sections of the longitudinal beams of one tier are joined together end-to-end without protruding parts using U-shaped inserts through bolts through spacer sleeves while the size of the barrier fence from the front side of the maximum projecting beam to the rear wall of the rack rod - for a one-sided fence and to the front side of the opposite beam - for a two-sided fence is, respectively, in the ranges from 0.25 to 0.50 m for a one-sided fence and from 0.4 to 0.8 m for a double-sided fence, and the ratio of the specified dimension to the height of the fence is 0.17-0.63 for a unilateral and 0.4-1.1 for a double-sided fence.

The closest analogue is a barrier barrier for roads (patent RU2595121, publ.: 08.20.2016.), Containing vertical columns and longitudinal beams attached to them located along the carriageway, characterized in that the columns are made of I-beam profile, to which longitudinal beams are mounted, which are an asymmetric C-shaped profile with additional shelves bent inward to the section, where crimping (reducing the overall dimensions of the section profile) is made on one side of the beam in this way ohm, that during the installation of the structure, longitudinal asymmetric C-shaped beams are inserted into each other and attached to the shock absorbing consoles on the lower tiers and to the consoles supporting on the upper tiers, which form, in connection with the longitudinal beams, a spatial truss fastened by the hardware group representing a T-shaped pin with a fixing elastic sleeve, which is made in such a way that the pin passes through the longitudinal slot of the asymmetric beam, being in a horizontal position, then deploying 90 ° relative to the axis of the pin and leaning in the opposite direction, abuts against the inner bent flanges of the beam and due to bends on the T-shaped jumper not only allows it to go outside, but also to turn around its axis, which ultimately allows you to set the T-shaped hairpin directly in any place of the beam and, accordingly, install the racks in the design of the fence with any step.

The technical problem of the prototype and other known solutions is that in them the longitudinal beams of the double-sided fencing form a structure in which, to ensure sufficient energy intensity, a large thickness of the beams with a large mass is needed. In addition, when a vehicle hits a fence, the longitudinal beams perceive the load sequentially, separately from each other, which also reduces the energy consumption of the fence structure.

The objective of the utility model is to eliminate the disadvantages of the known technical solutions.

The technical result is to increase the energy consumption of the design of the fence, the ability to withstand a large load with a smaller thickness of the beams and a smaller mass of the fence.

The specified technical result is achieved due to the fact that the claimed two-way barrier for roads containing vertical racks and attached to them longitudinal beams located along the carriageway, characterized in that the longitudinal beams are fixed to the vertical rack through the bracket, which is a metal plate, in the upper part of which there is a mounting hole through which both beams are fixed with a bolt connection, and in the lower part there is a fastener a bolt hole through which the bracket is bolted to the rack, and the lower part of the bracket plate has longitudinal bends of the edges, forming in the end section a U-shape made with the possibility of entering the interior space of the rack profile with touching the surfaces of the lower part of the plate of the inner surfaces of the rack.

It is conceivable that the upper portion of the bracket plate may be wider than the width of the strut.

It is permissible that the hole for fixing the bracket to the rack is made without a jumper.

Utility Model Implementation

The two-way road barrier contains vertical struts 2 and longitudinal beams 1 attached to them (see FIG. 1, FIG. 2, FIG. 3) located along the roadway.

What is new is that the longitudinal beams 1 are fixed to the vertical post 2 by means of a special fastening connecting element 3, which is a metal plate, in the upper part of which 8 there is a mounting hole 11 (see Fig. 13), through which both beams are fixed by bolt connection 1, and in the lower part 7 there is a mounting hole 12, through which the fastening connecting element 3 is fixed to the post 2 by bolting, and the lower part 7 of the plate of the fastening connecting element and 3 has longitudinal bends of the edges, forming in the end section a U-shaped shape, configured to enter the interior of the profile of the rack 2 by touching the surfaces of the lower part 7 of the plate of the inner surfaces of the rack 2.

The upper part 8 of the plate can be made wider than the width of the rack 2, which eliminates the failure of the element 3 inside the rack 2.

The hole 9 for fixing the fastening connecting element to the rack can be made with a jumper 10 (see Fig. 14) or without a jumper (see Fig. 13).

The lower part 4 of the bracket 3 allows you to securely install this element in the upper part of the rack 2 and fasten to it with bolts 4. The upper part 8 of the bracket 3, protruding from the upper plane of the rack 2 is a mounting point on both sides of the longitudinal beams 1 of a sinusoidal or other profile by bolts 5 and nuts 6.

A feature of the claimed double-sided barrier fence is the presence of a bracket 3, which allows to fix the longitudinal beams 1 to each other and the vertical strut 2, while significantly reducing the dimensions of the fence, the width of which is equal to the width of two longitudinal beams 1.

At the same time, the width of a standard double-sided barrier, known in the art, is calculated by the formula: two widths of longitudinal beams + rack width + two widths of the shock absorber console.

The longitudinal beams 1, assembled with each other according to the claimed utility model, form a structure with a significantly higher energy intensity, which can withstand a large load with a smaller thickness of the beams 1 (weight). An increase in the energy consumption of the structure occurs due to the fact that when a vehicle hits a fence, two beams 1 perceive the load at once, and in the "classic" known constructions of double-sided barrier fences, the longitudinal beams perceive the load sequentially, separately from each other.

As the rack 2 can be used, for example, the rack profile channel (Figure 4), I-beam (Figure 5), on the U-shaped profile (Figure 6), on the C-shaped profile (Figure 7).

In all of the above embodiments, the rack 2 is installed so that its plane of the rear wall is perpendicular to the beams 1.

In this case, the post 2 can be installed, as shown in Fig. 8, where the plane of the rear wall of the post 2 is parallel to the beams 1.

For this embodiment also, the rack 2 can be made in the form of a U-shaped profile (see Fig. 9), on a C-shaped profile (see Fig. 10), on a channel (see Fig. 11), on an I-beam (see Fig. 12).

Alternatively, the upper part 8 of the plate of the bracket 3 can be made wider than the width of the rack as shown in FIG.
