Definitions

  • the object of the invention is a method for connecting barrier elements together and disconnecting barrier elements from each other and a barrier placing in a side of a roadway comprising of barrier elements.
  • the object of the invention is defined in the preambles of the independent claims.
  • the road barriers can be used for separating lanes leading to different directions in order to prevent meeting accidents, as well as in the side of roads for preventing swerving from the road.
  • the experiences collected over years has led to guidelines, with which are aimed to steer the vehicle in accident along the barrier as safely as possible, preventing the vehicle to fall over the barrier or to dart back to the driving lane.
  • Steel structured barriers are well known and their design problems concern to discontinuity of the structure; horizontal structured barrier is connected to an upright bar at specified distance. In an accident situation the darting of the vehicle back to the driving lane depends on the distance of the bars, the stiffness of the horizontal structured barrier and the bar connection thereof.
  • the steel structured bars are more rigid than horizontal structures and when a car hits to the bar it easily darts back to the drive lane without control. If the car falls to its side before hitting the barrier, the bars can shear inside the car with mortal results.
  • concrete barriers have certain advantage over the steel barriers. Due to the absence of the upright bars the continuous concrete barrier is safer than the steel barrier.
  • the concrete barrier is mountable straight to the surface of a road or to the shoulder of a road without a foundation, while the bars of the steel barrier have to be pushed into the ground.
  • the continuity of the concrete barrier is achieved by connecting single barrier elements together with sufficiently rigid connecting member. In collision situation the concrete barrier acts as a chain, which moves to aside, and wherein the link in the chain are the elements and the connecting members, as well as the meetings between the elements acting as joints with certain stiffness.
  • the concrete barrier structures has been developed in recent decades, in order to provide better mountability, dismantlement and remounting, if necessary, so that the traffic safety can be ensured in a collision situation.
  • Such inventions are presented in publications e.g. EP0589073 , EP0715026 , EP0826833 , EP1650353 and FR2862673 .
  • Common to these inventions is that there are anchoring parts in the end of the elements forming a top-open slots or grooves.
  • the adjacent anchoring parts are connected together with a connecting member, which has hooks or T-shaped end thickenings at the ends of the member.
  • a top-open slot weakens the strength of the concrete end in environmental conditions with humidity and temperature variations of the both sides of zero Celsius degree.
  • a top-open slot has to be jointed or shield plugged in order to prevent frost damages. If the slot is formed only to the upper part, the connecting member has to be pressed into place either manually or mechanically, so on the behalf of mounting, the joint clearance must be large enough, which in turn affects negatively the impact sustainability of large vehicles. If the slot is formed as continuous from the top to the ground, the moisture can be led away from the bottom and take advantage of the element's own weight in mounting, basically, but in practice, leaves and other trash may be flocked in such an open slot structure, which may finally prevent the free flow of water out of the slot and, when the water freezes, may cause cracks to the barrier element, which reduce the structure of the barrier element and the impact sustainability thereof. In addition, in this type of slot structure is forced to use more corrosion protected steel, which makes this solution expensive to implement.
  • the objective of the invention is to improve driving safety by presenting a new kind of road barrier consisting of barrier elements, by means of which the foregoing problems can be eliminated or they can be significantly alleviated.
  • One object of the invention is to create a barrier, which, compared to previously known solutions, is more resistant to varying weather conditions, and in which the impact sustainability of the interconnections are in the requested level.
  • One object is also to provide a method, in which both the connecting and disconnecting of barrier elements is quick and easy.
  • the objects of the invention are achieved with a solution, wherein the barrier elements are connected to each other with a connecting member, which connecting member is placed in an anchoring part of the barrier element through a slot part formed to the barrier elements and is fastened in the anchoring part with a fastening means.
  • the barrier elements are also easily disconnectable by removing the fastening means, in which case the elements can be exchanged or transferred and reconnect.
  • a barrier according to the invention is characterized by the features disclosed in a corresponding claim 1.
  • a method according to the invention for connecting two barrier elements together with the connecting member is characterized by the features disclosed in a corresponding claim 8.
  • a method according to the invention for disconnecting two barrier elements from each other is characterized by the features disclosed in a corresponding claim 13.
  • connection structure of the barrier elements can endure without breaking collisions of large vehicles.
  • the barrier element according to the invention and the connection member thereof is easy and inexpensive to manufacture and simply to mount. The possibility to disconnect the elements may provide savings also when, for example in collision situation, only the damaged parts can be replaced with new ones and leave the undamaged elements in place.
  • Fig. 1 depicts, as a perspective view, a barrier element according to the invention.
  • the barrier element 102 comprises at least an element part 104, a slot part 106 formed at least another end of the barrier element, an anchoring part 108 formed in the slot part, which anchoring part 108 is preferably attached to the element part 104 with longitudinal reinforcing parts 110 and which anchoring part 108 is formed to the barrier element 102 so that the element part 104 extends over the top of the anchoring part 108 forming a shield for the anchoring part 108.
  • a ceiling part 112 may be attached on the top of the anchoring part 108.
  • a connecting member led through the slot part 106 to the anchoring part 108, may be fastened in the anchoring part 108 with fastening means 114.
  • the shape, height and width of the barrier element 102 may vary depending on the intended use, but the barrier element 102 shown in Figure 1 , is similar to a protective barrier for roadway according to Finnish regulations.
  • the height of such barrier element may be, for example, about 900 mm or 1000 mm and the width, for example, about 4 m and 8 m.
  • the element part 104 of the barrier element is preferably manufactured from cast stone material, such as concrete, but element part 104 can also be manufactured from other suitable material for the purpose.
  • the element part 104 may be solid or it may have been provided with cavities during the casting to reduce the weight of the element part 104.
  • the barrier element 102 intended to be a protective barrier must be solid, at least in the parts, which it is reinforced with the reinforcing parts 110 of the anchoring part 108.
  • the element part 104 may also be reinforced with longitudinal reinforcement bars, which are anchored with links bent to U-shape, as well as with hook pins and horizontal links. The meaning of the reinforcement is to improve the impact sustainability of the barrier element and to prevent the formation of darting element pieces, for example from the end parts of barrier elements, in a collision situation.
  • the slot part 106 is provided to at least another end of the element part 104.
  • the slot part 106 is formed to be proceeding substantially vertical position in relation to the barrier element 102, beginning from the bottom of the barrier element 102, but the slot part 106 may also be formed to be proceeding in the barrier element 102 in another angle, for example diagonally in relation to the barrier element 102.

  • Narrowing parts 126 may extend from slot part 106 to end part of the element part 104, but it is not necessary. Between the narrowing parts 126 remains a groove having same direction than the slot part 106, which width of the groove is greater than thickness of a plate part 118 of the connecting member shown in Figure 3 , but less than the thickness of the connecting member 116 in the spot of a thickening part 120.
  • the narrowing parts 126 extend along the side walls 122 of the slot part at most so deep to the slot part 106 that the thickening part 120 of the connecting member is able to pass in the slot part 106.
  • the narrowing parts 126 are preferably rigid and durable material, such as bent steel or angle irons.
  • the narrowing parts 126 of the anchoring part may also be connect to one another by means of the ceiling part 112 (as shown e.g. in Fig. 1 ).
  • the narrowing parts connected by the ceiling part 112 can distribute forces originated from the collision situation to the whole end structure, which may improve the impact sustainability of the barrier element.

  • Parts such as bent steel panel or plastic or some other corresponding material, improving the guiding of the connecting member 116, may be attached to the slot part 106 in the spot of the anchoring part 108 (not shown).
  • the anchoring part 108 is attached by the reinforcement parts 110 to the aggregate material of the element part 104 or the material, from which the element part 104 is manufactured. This aims to improve the impact sustainability of the barrier element 102.
  • the reinforcement parts 110 of the anchoring part are preferably longitudinally attached to the element part 104.
  • the reinforcement parts 110 may be, for example, longitudinal reinforcement bars commonly used in concrete elements, which reinforcement bars are bent to U-shape, for example, for anchoring to the element part 104. Reinforcement parts 110 may also be other suitable materials for reinforcing concrete.
  • the fastening means 114 are placed below the anchoring part.
  • the fastening means are discussed more closely in context of Figures 6a-6c .
  • the place of the anchoring part in the element part may vary depending on the purpose of use of the barrier element.
  • the anchoring part is placed in the bumper level or higher, in which case the impact sustainability of the barrier may improve and the fall of the barrier element in collision situation may also be prevented.
  • the place of the anchoring part in the element part 10 may thus be, for example about between 550 mm - 900 mm from the ground level, also depending on if the barrier element is placed to asphalt for separating lanes or beside the road, in which case the barrier element is approximately 10 cm below the surface of the roadway asphalt set into crushed stone.
