Description

Field of technology

The utility model refers to a road restraint system that will find application in road construction, repair and maintenance activities, and in particular to ensure adequate safety of road infrastructure and road users.

BACKGROUND OF THE INVENTION

The main means of ensuring adequate security of road infrastructure are road restraint systems. They are a guarantee for greater safety of passengers on the roads, a guarantee for less damage to motor vehicles in the event of a collision with them and last but not least - saved lives.

The main characteristics of restraint systems are: degree of restraint, showing the ability to restrain vehicles, depending on their mass, angle and speed of impact; Range defined by the distance between the restraining side of the restraint system and the maximum dynamic lateral displacement of each of the restraint elements in the impact test and the degree of impact force assessing the load on the body and the severity of the occupants' injuries on impact.

The restraint systems partially absorb the kinetic energy of the impact of the vehicle in them. The system must keep the vehicle in a controlled condition, without breaking the main elements of the fence, and without distortion or deformation that could cause damage to passengers. The main purpose of restraint systems is to protect drivers and passengers in vehicles from significant injuries.

In practice, restraint systems with different levels of restraint and areas of action are generally used, but do not provide rear protection for pedestrians and cyclists. Due to the fact that the fasteners (bolts) of the system are protruding behind it and in the event of a collision in them, the cyclist or pedestrian may be injured.

Technical essence of the utility model

The task of the utility model is to create a road restraint system that will provide adequate protection of the road infrastructure and protection of drivers and passengers in vehicles from significant injuries, as well as to provide protection to other road users - motorcyclists, cyclists and pedestrians.

The problem is solved by creating a road restraint system, which includes steel poles located at a distance, on which horizontal rails are fastened at the front by means of connecting elements. L-shaped safety elements are mounted on the rear and top of the steel poles by means of self-tapping screws.

The problem was solved by creating a second road restraint system, which includes steel poles located at a distance, with brackets mounted on them, on which horizontal rails are attached at the front by means of connecting elements. L-shaped safety elements are mounted on the back and top of the brackets by means of self-tapping screws.

Road restraint systems also include studs for anchoring the pillars to the foundation.

The horizontal rails of the road restraint systems have two or three waves - type 2N or 3N or are W-shaped.

The advantage of the created road restraint systems is the possibility to protect cyclists or pedestrians from injury by installing the safety element in case of possible contact with the safety systems.

Explanation of the attached figures

This utility model is illustrated in the accompanying figures, where:

Figure 1 is a cross-sectional view of a roadway restriction system with a horizontal three-wave rail;

Figure 2 is a cross-sectional view of a restraint system for a horizontal installation

4676 double wave bus;

Figure 3 is a cross-sectional view of a road restraint system with a bracket and a horizontal two-wave rail; and Figure 4 is a cross-sectional view of a restraint system for a bracket and a W-shaped horizontal rail.

Examples of implementation of the utility model

The created road restraint system includes steel poles 3, located at a distance, at which horizontal rails 2 are fastened at the front by means of connecting elements 4. L-shaped safety elements 1 are mounted on the rear and upper side of the poles 3 by means of self-tapping screws.

A second road restraint system has been created, which includes steel poles 3 located at a distance, with brackets 6 mounted on them, on which horizontal rails 2 are fastened at the front by means of connecting elements 4. self-tapping screws are mounted L-shaped safety elements 1.

The created road restraint systems also include studs 5 for anchoring the pillars 3 to the foundation.

The horizontal rails 2 of the road restraint systems have two or three waves - type 2N or 3N or are W-shaped.

The main purpose of the established road restraint systems is to protect drivers and passengers in vehicles from significant injuries. In order for a safety system to provide protection to other road users - motorcyclists, cyclists and pedestrians, additional safety elements 1 are installed to provide the necessary safety.

The safety element 1 for road restraint systems is an L-shaped steel profile S235 or S355 with certain dimensions depending on the type of restraint system. Its length is in the range from 1 w to 4 w depending on the distance between the pillars of the respective safety system. The safety element 1 is mounted by means of connecting elements - self-tapping screws. Specially selected fasteners provide a smooth surface that helps to perform its main function.

The road restraint system with safety elements is suitable for installation between a road and a bicycle lane and between a road and a pedestrian zone.

The created road restraint systems are used both for road parts and for facilities, such as bridges and overpasses.

The restraint system with safety elements for cyclists and pedestrians by means of its smooth surface, in addition to protection, can also be used for marking and signaling purposes. Safety elements can be fitted with special signal stickers / foils, etc., to guide or warn pedestrians and cyclists of various traffic situations for their safety.
