Fencing of roads

 

(57) Abstract:

Use: rehabilitation of roads. The inventive enclosure contains material elements 1, placed at an angle to each other and interconnected in pairs by flexible connections 5 and 6 cables, and the bushes 4. Material elements 1 made in the form of rods extending from the center of the element 1 at equal angles, and freely installed on the ground in bushes 4. Upon impact of the vehicle in the fence freely set elements 1 before the shock front approach among themselves, and on the other hand disagree, deforming the largest surface of the elastic branches of the Bush 4. 5 Il.

The invention relates to the separation lanes of highways and has a high shock absorption.

Known elastic enclosure (ed. St. N 1017759, 1983), containing strung between the posts ropes hung on them shock-absorbing elements of the tires.

The disadvantage of analogue is that near him trapped exhaust gases, dust, snow and other

Known fencing of roads (ed. St. USSR N 852998, 1971), containing the first material.

The disadvantage of analogue is that the bulk material from the blow falls into the oncoming lane, which may be the cause of the accident.

The closest analogue, as to the technical essence and purpose, is the fencing of roads (application Germany N 2337498, 1975), contains a number of material elements, interconnected, and Bush entered in the specified range.

The disadvantage of the prototype is that it has a low energorashodyi properties and low flexibility and adaptability of the installation.

The technical problem of the invention increase the intensity of the fence and its sustainability, as well as increasing the ease of installation.

The solution of the stated problem is achieved by the fact that the fencing of roads, containing a number of material elements, interconnected, and Bush entered in the specified range, according to the invention the material elements made of rods extending from the center at equal angles to each other, with material elements placed on the base at an angle to each other and connected in pairs by flexible connections, and together by a common rope.

In Fig. 1 itbrain of the material of the structural elements of the fence; in Fig. 5 pairwise connection material elements.

In Fig. 4 the following notation: l is the distance between the end points of the rod material elements; L the angular setting of the rods; a

the geometric parameter of the profile rods.

Fencing of roads contains a number of interconnected material elements 1, a strip of Bush 2 made in the specified number of material elements 1. The latter made each of the rods 3 extending from the center of the element 1 at equal angles of 120oto each other. And material elements 1 are placed on the base 4 at an angle to each other and connected in pairs by flexible connections 5, and between a common cable 6.

The fence works as follows.

In an accident in the event of a collision of the vehicle, directed along the fence road, freely installed material elements 1 located before the shock front, closer to each other. Moreover, the elements 1, positioned on either side of the shock front, stretched flexible relations 5 between them. The energy of the blow much is absorbed due to the deformation of the strip custno and shear strain in each pair are interconnected at an angle members 1 design. A common connecting cable 6 allows quick installation of fencing on the base 4 in the case of construction or overturning the result of the impact of vehicles. The construction material of the element 1, made of rods 3 extending from the center at equal angles a to each other, has considerable resistance.

Fencing of roads, containing a number of material elements, interconnected, and Bush entered in the specified range, characterized in that the material elements are made of rods extending from the center at equal angles to each other, with the elements placed on the base at an angle to each other and connected in pairs by flexible connections, and between a common cable.

Novelty is that each post rests on apron of height H made of sheet steel, thickness S, and provided with vertical and horizontal members of different areas and with inclined widening downwards trapezoidal member in between, whose side edges of width (1.7-1.8)S are bent inwards the railing through 45°. Hole is made on vertical member for fastening to post. Holes on horizontal member are designed for anchor bolts. Angle of inclination of trapezoidal member to horizontal is 60° at its length being (o.64-0.67)H. Intermediate vertical member of width equal to width of horizontal member and with height within (0.110-0.125)H is made between trapezoidal member and horizontal members. Ratio of widths of vertical and horizontal members is 0.30-0.34. Apron can be provided with second inclined and second vertical members arranged symmetrically relative to vertical axis of post relative to other inclined and vertical members.

SUBSTANCE: guard barrier comprises vertical posts and longitudinal beams arranged along road and secured to them. The posts are formed of U-type roll-formed shapes or of two U-type roll-formed shapes connected with each other or of C-type shape. Longitudinal beams are formed of C-type shape provided with additional flanges bent into the shape section.
