The road buffer

 

(57) Abstract:

The invention relates to the construction and for the construction of roads for visual orientation and the direction of traffic, and also to bypass the obstacles and retention of vehicles stopping at a frontal impact front protected by a barrier in the case of using the buffer complete with road sections. Hollow body buffer is made of plastic, such as polyethylene, and has a base, a top surface and four walls. The front and rear walls are made convex, and flat side walls parallel to each other. The front wall has a cylindrical shape. The back wall is made with a radius of curvature greater than the radius of curvature of the front wall, and provided with attachment points for connection with the return nodes of joined sections if necessary. The upper surface has three sections. Flat horizontal section is from the plane of articulation of the front wall with the side walls towards the back wall. From the horizontal plot forward and backward depart two sloping down flat plot. Tilt the front of the site is 15o10ofrom the horizontal square is lthat of the invention is to improve the safety of repair work by providing a high degree of damping forces of the shock when hitting a vehicle on the fence, to improve the usability of the buffer, and providing a good appearance and visual perception. 11 C.p. f-crystals, 7 Il.

The invention relates to the field of construction and arrangement of roads and intended primarily for visual orientation and flow direction of the road when approaching places of road works, road junctions, to bypass the obstacles (pillars of bridges, viaducts and other), and complete with road sections PC D-1.85-45/1.0-TU 52 16-010-17152852-98 to hold and stop the vehicle in a frontal impact front protected by a barrier.

Known traffic separation unit, used for fencing venue repair work (certificate for utility model 8373, E 01 F 15/00, publ. 16.11.98). The unit is made in the form of hollow containers made of polymeric material formed from two connected on a path identical parts made of polyethylene. The execution of the block of two halves allows the manufacture of a two-tone block (for example, one side red, the other white), which is convenient in operation and the creation of alternating colors.

A well-known sign to be used for fencing strouble the than two located opposite to each section have a greater horizontal dimension, and the other two, also located opposite each other, the smaller horizontal dimension (see patent UK 1172460, E 01 F 9/02, 1969).

The technical problem solved by the invention is to increase the safety of repair work due to the high degree of damping forces of the shock when hitting a vehicle on the fence. If this solves the problem of creating facilities in operation due to the elements, allowing maintenance staff to raise, rotate and move the buffer. In addition, easy to use form, while maintaining a high degree of damping-end collision of a vehicle, has a good appearance and well perceived visually.

The problem is solved due to the fact that the road buffer containing hollow body made of polyethylene or plastic, formed by the base, the top surface and four sidewalls, the front has a convex cylindrical shape, two flat side walls parallel to each other, the back wall is made convex and provided with attachment points designed for the connection, if necessary, with a return nodes of joined sections.

When this upper powsociety front cylindrical with flat side towards the back wall, and two exhaust from this horizontal section forward and backward sloping down flat sections, and the angle of inclination of the front of the site is 15o10ofrom the horizontal plane, and the slope of the rear section 55o30ofrom the horizontal plane. In addition, on the upper surface of the housing on the rear inclined part made a hole closed by a plug.

The attachment points designed for the connection, if necessary, with a return nodes of joined sections, can be made in the form of two series of loops forming when connecting through bolt the two joined sections with hinge hinge hinge, allowing positioning of joined sections parallel to each other or at an angle up to 30o.

While the base can be made flat with two pairs of symmetrical relative to the plane of symmetry of the housing slots with walls perpendicular to the base and a sloping bottom, and the grooves are directed towards each other from the front and rear walls and are designed to connect with anchors that are installed on the road surface, and the front cylindrical wall can be accomplished with three recesses, each of cotogno of recesses located in the symmetry plane of the casing, and the other two symmetrically with respect to this plane. In addition, the convex rear wall is also made with a similar recess with a hole located in the symmetry plane of the body.

The body cavity can be filled with ballast, the volume of ballast is not less than 600 HP as ballast can be used with water or sand.

In addition, polyethylene or plastic, which made the case for a buffer that can be painted in red or yellow color in the manufacture of the housing and for drawing characters detour on the surface of the case it is possible to paste a picture of the sign, made of reflective film.

The technical result achieved by the invention, is that first and foremost provides a high degree of damping forces of the shock in case of a collision of the vehicle to the buffer due to the formation of box-shaped design with a more pliable front wall. The combination of a cylindrical front wall of the buffer which is being deformed, absorbs the kinetic energy of the vehicle and two parallel flat walls connected by a convex wall of the lesser curvature, supported by the attachment points CLASS="ptx2">

Additional fastening buffer to the road surface, provide established elements (grooves on the base, the grooves with holes for fasteners on the walls), gives an incremental effect and allows you to securely attach the buffer to the place of its installation, without fear of bias because any effects (except strike vehicles hitting the buffer).

The cavity filling buffer cheap ballast (sand, water) significantly increases its mass, which in combination with the above-described shape of the hull allows you to successfully extinguish even the windshield blows a vehicle.

Perform body buffer, for example, from polyethylene for rotational molding, light-resistant to UV radiation, makes the production buffer-tech and cheap. In addition, this material allows you to paint the product in the desired color (yellow, red), and stick to it reflective film with the image of the sign detour.

The invention is illustrated by drawings, where:

in Fig.1 presents a General view of the road buffer;

in Fig.2 is a rear view of the buffer;

in Fig.3 is a bottom view of the buffer;

in Fig.4 - section a-a of Fig.3 (fragment);

in Fig.5 - IP is Apatite;

in Fig.7 - use the buffer at the junction.

The road buffer formed hollow housing 1 and may be made of polyethylene for rotational molding, light-resistant to UV radiation or plastic material with the appropriate properties. The housing 1 comprises a base 2, a top surface and four walls.

The front wall 3 has a convex cylindrical shape, two flat side walls 4 are parallel to each other, and the rear wall 5 is made convex with a large radius of curvature and provided with fasteners 6. These sites are designed to connect the buffer to the response nodes joined workers of road sections 15 (sections not included in the design of the buffer).

The upper surface of the case is made of three sections: a flat horizontal section 7 located from the plane of articulation of the front cylindrical with flat side towards the back wall, and two exhaust from this horizontal section forward and backward sloping down flat sections 8 and 9.

The slope of the front section 8 of 15o10ofrom the horizontal plane, and the slope of the rear section 9 55o30ofrom horizontal hole, closed by a plug 10. Fasteners 6 for connecting with the response nodes of joined sections, can be made in the form of two series of loops forming when connecting via pin loops of two joined sections of the hinge joint. This hinge allows you to place the joined work of road sections parallel to each other or at an angle up to 30o. Over the loops of the upper surface is another horizontal section 15.

The base 2 of the housing 1 can be made flat with two pairs of symmetrical relative to the plane of symmetry of the housing grooves 11. The walls of grooves perpendicular to the bottom, and the bottom 12 is inclined at an angle to the base, the grooves 11 are directed towards each other from the front 3 and rear 5 of the wall and are designed to connect with anchors that are installed on the road surface (not shown).

The front cylindrical wall 3 can also be carried out with three recesses 13, each of which has a hole 14 that is designed for the fastening element (not shown) for connection with the road. One of the recesses 13 have in the symmetry plane of the casing, and the other two symmetrically with respect to this plane.

The cavity of the housing 1 can be filled with ballast, the volume of ballast shall be not less than 600 HP as ballast can be used water (in summer) or sand (in the winter). The ballast is filled (filled through the hole in the case), then the hole is closed by a plug.
