Description

The utility model belongs to road construction, namely: - to the means intended to increase safety on highways; - reducing the possible departure of vehicles from the highway on bridge structures, overpasses, dams, sharp turns; - driving into the oncoming lane and colliding with a vehicle; - hitting buildings; - going to the roadside; - falling of vehicles from the roadside into a ditch and mountain terrain into a cliff; - injury to people in vehicles against various types of highway guardrails.

From the state of the art, there are known types of fences, which include posts with limiting elements attached to them (directly or with the help of bolts) (made of profiled metal strips), the main task of which is to prevent the movement of vehicles in prohibited (dangerous) directions, as well as dispersion of impact energy when a vehicle collides with a road barrier | GOST 26804-86 "Barrier-type metal road barriers"). The energy of the impact is dissipated due to the deformation of the limiting elements made in the form of corrugated tape, their fastening nodes and the elements of the vehicle, due to the friction that occurs between the elements of the vehicle and the road fence.

Disadvantages of this type of highway constructions are: - constructions have high rigidity and low degree of deformation and energy absorption; - the vehicle is kept on the road in the event of a collision, but receives significant damage; - high trauma in the event of a collision and damage to drivers and passengers, because the elements of the fence can penetrate the inside of the vehicle; - the guard works on deformation and damping only by one area of the collision, significantly limiting the energy absorption of the impact during the collision.

From the state of the art, a road inertial damping system is known, which can be used to protect cars when they hit stationary obstacles and reduce the number of fatal road users. The technical result of the declared useful model of the road inertial damping system is an increase in the efficiency of extinguishing the energy of the shock pulse when the car collides with this system. The specified technical result is achieved due to the fact that the front bumper, made in the form of a movable buttress

From the support installed on the guides with the possibility of movement, necessary for damping the impact energy, which is carried out due to the ""dry" friction of movable inertial dampers in the form of plates located between the guides and driven by a system of cables connected to the bumper, while the back reaction of the damping system is excluded (Patent KO Mo 66 356 01 IPC: EOTE 15/00. Road inertial damping system / Inventors:

The disadvantages of this type of construction are: - complexity of manufacturing and its high cost; - insufficient technical and economic indicators during the movement of massive slabs in the winter period (freezing, snowing, etc.), in the autumn-spring period, water and mud clogging of the movement guide rollers, movable structural elements.

The closest analogue, known from the state of the art, is a road anti-shock damping system, which is designed for more effective protection of human life and health in road traffic accidents (hereinafter referred to as road accidents), in particular in the event of a head-on or tangential collision of a car with traffic flow dividers and barrier fences. The result is achieved due to the implementation of the system in the form of articulated sections, installed on steel cables, laid on the base along these sections, inside which are located all-metal cable damping elements of quasi-zero stiffness. Sections are sequentially connected to each other with the help of corrugated walls of the fence, which in the event of a collision enter into each other in this way, and the shock load is absorbed by cable damping elements. Moreover, the system is located on the support cables from below and moves along them upon impact (like on rails). The system is restored in a short time to 100 95 tension with a tow rope, does not require replacement of damping elements. Being completely all-metal, it is not subject to the influence of aggressive environments, temperature, atmospheric precipitation, it is fireproof, it does not have scarce materials and nodes (Patent KO Mo 60 947 01 IPC:

EOTE 15/00. Road anti-shock damping system // Inventors: Mansurov O.Y (KU), Mansurov I.Ya (KU)) /Patent holder: Mansurov O.Y (KU), Mansurov I.Ya (V) // Application: 2005130737/03, 05.10.2005, Date of publication: 10.02.2007. Bul. Mo 4). because the disadvantages of this type of construction are:

- complexity of manufacturing and its high cost; - insufficient technical and economic indicators of corrosion in the winter period (freezing, snowing, etc.), in the autumn-spring period clogging of all-metal cable damping elements with water and dirt.

The useful model is based on the task of creating a construction of a road damping fence that would provide: - high technical and economic indicators; - simple reliable repairable construction; - convenience in production; - ease of maintenance and repair; - Increasing the contact zone of the vehicle with the fence in the event of an accident; - Increasing the damping properties of the fence; - cost reduction due to lack of use of expensive and scarce materials; - to reduce maintenance and recovery costs after a collision with a vehicle; - to increase impact absorption in the event of a tangential and lateral collision of a vehicle with a fence; - to increase the period of reliable operation by increasing the damping properties in the event of a collision (traffic accident).

The task is solved by the fact that the damping fence is made in the form of profiled metal strips (hereinafter - the beam) inside in the recess with the help of tension brackets (hereinafter - the bracket or tension bracket) ropes (steel, galvanized, which were in use, segments) are laid along the length ropes, etc.). The lower part of the tension brackets is attached to the inside of the beam by welding one section of the beam, then edges are laid in the gutters and the upper part is pressed, the adjacent beam is mounted overlapping on the outside of the first beam and with the help of bolted connections the entire structure is tightened into a single unit, joints sections of beams are mounted on vertical racks that are fixed in the foundation.

Damping protection is installed on highways, bridges, overpasses and has:

Ko) beam; stable; ropes; bolted connections; clearances; consoles; clamping bracket (bracket); the lower part of the bracket; the upper part of the bracket; damper block; metal plates, thus forming a single structure of the device in which the ropes are placed inside the beam in several layers in horizontal and vertical directions; tension brackets consist of upper and lower parts, between which there is a gap and landing grooves for ropes; the lower part of the tension bracket has an external surface in the shape of a sector; damper blocks are installed on racks and ropes are pulled through them; the ropes are installed along the length alternately in a larger number in the corresponding areas.

The lower part and the upper part of the tension bracket have landing grooves under the ropes with the help of which, bolted connections and a gap tighten the ropes between the parts of the bracket.

The ropes are placed inside the beam in several layers in the horizontal and vertical directions, the tensioning brackets are mounted inside both half-waves of the beam from above and below, the ropes are laid in the brackets: in a single row; two-row or more, depending on the amount of damping.

The racks consist of an I-beam, which is installed with a certain step 5 on the foundations, the ropes are fixed inside the beam with the help of tension brackets, which are attached to the racks on both sides with the help of shock-absorbing consoles, damper blocks are installed inside the beam with a certain step, through which the ropes pass.

When the vehicle hits the damper fence, the beam bends and pulls the ropes in the adjacent areas, while the energy of the impact is absorbed by pulling the ropes through the damper block and braking the ropes in the tension brackets, while providing a high holding force of the vehicle on the road.

When installing a damping fence in some relevant areas (bridge structures, overpasses, dams, sharp turns), ropes are installed alternately in a larger number and of a smaller diameter, that is, when a vehicle collides with a damping fence, the ropes have a larger area of friction against the gutters of the brackets, they can break, when it absorbs even more impact load.

To increase impact damping in critical areas (turns, etc.), the beams are reinforced with ropes, which are installed on both sides of the racks in two tiers and stretched by the ends of the rope segments behind the bottom of the racks.

The tension of the ropes in the tensioning clamps takes place beforehand in different directions to prevent tilting of the racks, the ends of the ropes in the clamps are fastened with the help of collet fasteners, and the ends of the ropes on the slopes are attached to the bottom of the racks to hold the fence in case of an accident.

The one-sided beam is reinforced with ropes and is attached to the racks (made of channel, which are fixed to the foundation) with the help of a console with a rigid bolted connection, the overlapping joint of the beams is placed on the racks and fixed with a bolted connection.

To increase the damping properties of the device, annular metal plates (brake) made of soft metal (lead, tin, plastic, etc.) are installed on the cantatas in front of and behind the bracket with rubber annular layers between them, for deformation in the event of an accident and shock absorption.

Ropes are made of: steel; - galvanized steel; - combined (steel with polymers); - from composites.

The internal landing channels of the tension brackets have soft metal plates inside.

In some cases, ropes are used in sections to strengthen the damper fence, which are connected to each other with a screed.

Galvanized ropes are used for damping fences in places where the air temperature is persistently low in winter, and to prevent corrosion.

In some cases, where the dimensions of the damper enclosure allow, tension levers and rubber spacers with metal plates (brake) made of soft metal between them are used for constant rope tension and damping.
