Abstract:
A barrier (301) includes recycled rubber portions (101) and a binder (102) molded around a core infrastructure (401). The core infrastructure may itself include a filler material (404) in the form of recycled rubber in a containment body (401). The containment body may include baled recycled or other waste material. The barriers may be stacked or connected to form a barrier structure useful in environmental control and other applications. The method for making the barriers includes molding rubber portions and a binder around a core infrastructure.

A crash barrier system for forming a crash barrier comprising a plurality of barrier units, each barrier unit comprising: a body having at least one crash wall, the body defining a cavity for receiving ballast; the crash wall comprising a series of longitudinal grooves on the outside surface thereof, each groove adapted to house a reinforcement bar; wherein a first barrier unit is connectable to an adjacent second barrier unit by locking pins; at least one locking pin able to pass through apertures in the body of the first barrier unit and reinforcement bar(s) housed in the crash wall of the first barrier unit, and through apertures in the adjacent second barrier unit and reinforcement bar(s) housed in the crash wall of the adjacent second barrier unit so as to lock the barrier units together to form the crash barrier.
Abstract:
Die erfindungsgemäße Verkehrsleitwand (10) besteht im Wesentlichen aus einer Vielzahl von in Wandlängsrichtung hintereinander angeord- neten Wandabschnitten (12) die an ihren Stirnseiten miteinander ver- bunden sind. Im Inneren der Wandabschnitte sind diese mit in Wand- längsrichtung verlaufenden Hauptbewehrungen (17a, b, 18a, b) be- wehrt, die an an den stirnseitigen Enden der Wandabschnitte angeord- neten Wandverbindern (15) angeschlossen sind. Um im Falle eines Un- falls eine möglichst gleichmäßige Belastung der Wandabschnitte über deren Querschnitt zu erreichen und die seitliche Auslenkung der Wand im Falle eine Anpralls zu verringern, ist erfindungsgemäß vorgese- hen, dass die Wandabschnitte mindestens je zwei paarweise nebenei- nander angeordnete Hauptbewehrungen aufweisen und die miteinander gekoppelten Wandverbinder zweier benachbarter Wandabschnitte Beweh- rungsumlenkungen bevorzugt durch Ausbildung von Kreuzungskupplungen (16) unter Wechsel der Zug- und Druckseiten der paarweise angeordne- ten Hauptbewehrungen bilden.

Abstract:
A stackable roadside barrier (10) has an open base (12) and a closed top (18), and front and rear walls (14, 16) and end walls (20, 22). The front and rear walls (14, 16) and/or end walls (20, 22) taper from the open end to the closed end to allow one barrier to nest within another similar barrier. The barrier includes at least one open channel or the like defined at or near the base of the barrier, adjacent the front and/or rear walls of the barrier for receiving ballast such as sand or gravel either in bags or loose.
Abstract:
A crash cushion includes a plurality of resilient, self-restoring tubes each having a center axis and an interior surface. At least some of the tubes are positioned such that respective ones of the center axes are spaced apart in a longitudinal direction. The center axis of at least one tube is substantially perpendicular to a longitudinal axis extending in the longitudinal direction, with the tube defining a diametral plane intersecting and oriented substantially perpendicular to the longitudinal axis. The center axis of the tube lies in the diametral plane. One or more segments are positioned in the tube, with the segments, or portions thereof, disposed on opposite sides of the interior surface of the tube. Each of the segments or portions is symmetrically secured to the tube relative to the diametral plane, with the tube being substantially open between the opposing segments.
Abstract:
A block (100) for a lane separator having a first end with recess (132) and protrusions (131, 133) and a second end (140) with a complementary protrusion (142) and recesses (141, 143) such that the projections and recesses ( 131-133; 141-143) fit into the recesses and protrusions of the neighboring blocks of the same shape as the block (100), wherein the recesses and protrusions are provided with bores (160) adapted to receive a cylindrical locking pin (150). The base portion (110) having vertical side walls (111, 112) that prevents a vehicle from climbing onto the block. The locking pin (150) is formed of a hollow, deformable tube, so that kinetic energy of a collision to a greater extent than before deforms the block, and to a lesser degree the vehicle. The block is hollow and can be deployed manually without tools, and then filled with water, sand or similar to the desired weight. The lane separator can also be used as a foundation for signs, and more.

Abstract:
Increased resistance to displacement of a barrier or barrier sections, thereof in response to a lateral force without anchoring or bolting harrier sections together is achieved by providing an attachment arrangement near the top of an end of barrier sections which is capable of carrying a tensile force and developing that tensile force using a tightening bolt/n?t arrangement located at deflection stops at lower comers of the barrier sections to develop a compressive force. The barrier sections are thus rigidly attached together such that a lateral force applied to one or more barrier sections is partially transferred to additional attached barrier sections effectively increasing the mass against which the lateral force is applied. The tightening bolt/nut arrangements are retained by and are captive to the respective barrier sections when barrier sections are disassembled from each other.
Abstract translation:通过在屏障部分的端部的顶部附近提供附接装置来实现屏障或屏障部分的位移阻力,所述屏障或屏障部分响应于侧向力而不将锚固部分锚固或栓接在一起,所述阻挡部分能够承受张力,并且 使用位于偏转位置处的紧固螺栓/ Nt t布置产生拉力停止在阻挡部分的下角处以产生压缩力。 这些屏障段因此刚性地连接在一起,使得施加到一个或多个屏障段的横向力部分地传递到附加的附接屏障段,从而有效地增加施加侧向力的质量。 当阻挡部分彼此分开时,紧固螺栓/螺母装置被相应的阻挡部分保持并被捕获。
