Definitions

• the present invention relates to the field of reinforcement elements and reinforcement arrangements comprising such reinforcement elements.
• the invention relates to a reinforcement element and a
• reinforcement arrangement comprising such reinforcement elements for casting.
• reinforcements for casting comprise reinforcement rods or elements which are attached and/or connected to each other in structures. Such reinforcements have the disadvantage of providing a relatively poor load resistance to weight ratio. Furthermore, handling of the reinforcement rods and assembling them into reinforcement structures is a time consuming and heavy task.
• Reinforcement elements comprising a plate-shaped body of a row of consecutively coupled ring-shaped portions are known from WO2012/050515. Such reinforcement elements achieve an improved load resistance to weight ratio compared to conventional reinforcements. Various means for coupling two or more reinforcement elements together are disclosed in
• WO2012/050515 such as for example separate linking elements or interconnecting portions formed by not cutting out the entire circumference of the hole of an outermost reinforcement portion.
• An object of the invention is to provide a reinforcement element and a reinforcement arrangement comprising such reinforcement elements which allows the reinforcement elements to be more efficiently and conveniently coupled together compared to the state of the art. Another object is to allow an individual reinforcement element to be coupled to itself in for example a ring-formed reinforcement arrangement or any other curved shape. Yet another object is to achieve such a reinforcement element and reinforcement arrangement which may be easily manufactured.
• a reinforcement element for being positioned within a cast, wherein the reinforcement element comprises a plane sheet- or plate-shaped body of at least one row of at least two consecutively coupled reinforcement portions with waist portions there between. At least one of the reinforcement portions has an oblong through hole, and at least one end reinforcement portion at the end of the row of reinforcement portions has a peripheral width corresponding to the elongation of the oblong through hole such that the end reinforcement portion is lockable with the oblong through hole.
• the at least one end reinforcement portion at the end of the row of reinforcement portions has a peripheral width such that the end reinforcement portion is insertable in the oblong through hole in order to couple the reinforcement portions together.
• the peripheral width of the at least one end reinforcement portion corresponds to the length of the oblong through hole in its direction of elongation.
• the peripheral width of the at least one end reinforcement portion may be substantially equal to or smaller than the elongation or length of the oblong through hole in its direction of elongation.
• a short or non-elongated width of the oblong through hole is smaller than that of the peripheral outer width of the at least one end reinforcement portion in order to obtain locking.
• Each of the reinforcement elements comprises a sheet- or plate- shaped body of at least one row of at least two consecutively coupled reinforcement portions with waist portions there between. At least one of the reinforcement portions of the first reinforcement element has an oblong through hole. At least one end reinforcement portion at the end of the row of reinforcement portions of the second reinforcement element has a peripheral width corresponding to the elongation of the oblong through hole such that the end reinforcement portion is lockable with the oblong through hole.
• the invention is based on the insight that by making the through hole in at least one of the reinforcement portions forming the reinforcement element oblong or elongated such that the peripheral or outer width of an end reinforcement portion (i.e. a reinforcement portion disposed at an end of the reinforcement element) corresponds to the elongation of the through hole, the reinforcement element may be conveniently coupled to itself or to another reinforcement element by introducing and thereafter locking the end reinforcement portion into and with the oblong or elongated through hole.
• the end reinforcement portion may easily be introduced into the oblong through hole and thereafter turned to obtain an efficiently locked coupling.
• the oblong through hole and the peripheral width are configured to be lockable by insertion and turning.
• a reinforcement element having at least one oblong through hole has proven to achieve a load resistance to weight ratio which is not substantially impaired, and in some applications actually improved, compared to the known reinforcement element having circular through holes.
• oblong through hole refers to a through hole which is elongated in one direction, e.g. elliptical, oval, drop-shaped or the like. Put differently, oblong through hole refers to a through hole having a cross section in the plane being perpendicular to the bore direction of the through hole which is elongated in one direction. It is furthermore understood that the peripheral width of a reinforcement portion refers to the outer width of the reinforcement portion, e.g. the outer diameter of a reinforcement portion having a circular outer shape or the minor or conjugate diameter of a reinforcement portion having an elliptic outer shape.
• the reinforcement element and reinforcement arrangement according to the invention may be used for reinforcing for example concrete, EPS concrete (expanded polystyrene concrete), AAC (autoclaved aerated concrete), composite materials or the like.
• the oblong through hole is elongated in a non-perpendicular direction relative a lengthwise direction of the row of reinforcement portions. It is understood that lengthwise direction refers to the direction of the row or the direction of the line along which the reinforcement portions are arranged. It is also
• the row of reinforcement portions may be curved.
• the at least one end reinforcement portion may furthermore have a peripheral width such that the end reinforcement portion is insertable in the oblong through hole solely when the end reinforcement portion is in a rotated position relative the at least one of said reinforcement portions. Thereby, the end reinforcement portion is locked to the oblong through hole in the sense that it cannot be pulled out from the through hole in the lengthwise direction of the row (or in any other direction) except for in the rotated position.
• at least one reinforcement portion has an outer shape corresponding to that of its through hole.
• the at least one reinforcement portion may thus have the same oblong outer shape as the through hole.
• the at least one reinforcement portion may have the shape of an elongated or oblong ring.
• each reinforcement portion has a through hole. In yet another embodiment of the invention according to the first or second aspect, each reinforcement portion has an oblong through hole.
• each reinforcement portion has a smoothly curved periphery.
• the periphery of each reinforcement portion is smooth such that each reinforcement portions does not have any edges, which could be potential indications of fracture.
• the reinforcement element has a smoothly curved periphery. In other words, not only do the reinforcement portions have smooth peripheries, but the waist portions between the reinforcement portions are also smooth and the waist portions transcend to the reinforcement portions in a smooth manner, i.e. with a smoothly curved shape. Consequently, no edges, which could be potential indications of fracture, are present on the periphery of the reinforcement element.
• each of the waist portions has a smaller peripheral width than the peripheral width of the neighboring reinforcement portions.
• the peripheral width of the waist portions and the peripheral width of the reinforcement portions may refer to the outer width of the waist portions and reinforcement portions, respectively, in a perpendicular direction relative to the lengthwise direction of the row of reinforcement portions.
• the waist portion between the end reinforcement portion and its neighbouring reinforcement portion has a peripheral width which corresponds to, i.e. is substantially equal to, or slightly smaller than the short or non- elongated width of the oblong through hole of the at least one reinforcement portion.
• each waist portion has a peripheral width which corresponds to, i.e. is substantially equal to, or slightly smaller than the short or non-elongated width of the through hole or each through hole.
• the peripheral width of the waist portion and the width of the through hole may refer to the widths in a perpendicular direction relative to the lengthwise direction of the row of reinforcement portions.
