Description

REINFORCEMENT ELEMENT FOR CASTING AND REINFORCEMENT ARRANGEMENT COMPRISING SUCH REINFORCEMENT ELEMENTS
Field of the invention
The present invention relates to the field of reinforcement elements and reinforcement arrangements comprising such reinforcement elements. In particular, the invention relates to a reinforcement element and a
reinforcement arrangement comprising such reinforcement elements for casting.
Background of the invention
Conventional 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. These means for coupling together require extra steps in the manufacturing process and, in the case of the separate linking elements, may be inconvenient to handle during assembly. Summary of the invention
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.
These and other objects are achieved by a reinforcement element and a reinforcement arrangement comprising such reinforcement elements according to the independent claims. Embodiments of the invention are defined by the dependent claims.
According to a first aspect of the invention, there is provided 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.
In other words, 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. Put differently, 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. Thus, 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. According to a second aspect of the invention, there is provided a
reinforcement arrangement comprising a first and second reinforcement element. 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. Thus, by adapting the elongation of the oblong or elongated through hole to the peripheral or outer width of the end reinforcement portion, or vice versa, the end reinforcement portion may easily be introduced into the oblong through hole and thereafter turned to obtain an efficiently locked coupling. In other words, the oblong through hole and the peripheral width are configured to be lockable by insertion and turning.
Surprisingly, 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.
It is understood that 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.
In an embodiment of the invention according to the first or second aspect, 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
understood that the row of reinforcement portions and line along which the reinforcement portions are not necessarily straight. In some embodiments, 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. In another embodiment of the invention according to the first or second aspect, 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. For example, the at least one reinforcement portion may have the shape of an elongated or oblong ring.
In yet another embodiment of the invention according to the first or second aspect, 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.
In yet another embodiment of the invention according to the first or second aspect, each reinforcement portion has a smoothly curved periphery. In other words, 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. In yet another embodiment of the invention according to the first or second aspect, 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.
In yet another embodiment of the invention according to the first or second aspect, the inner periphery, i.e. the circumference of the through hole, of each reinforcement portion is smooth. Consequently, no edges, which could be potential indications of fracture, are present on the inner periphery of the reinforcement portions. In yet another embodiment of the invention according to the first or second aspect, each of the waist portions has a smaller peripheral width than the peripheral width of the neighboring reinforcement portions. In other words, the portions of the reinforcement element where the reinforcement portions transcend into neighboring reinforcement portion(s) are narrower than the peripheral widths of the 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.
In yet another embodiment of the invention according to the first or second aspect, 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. In yet another embodiment, 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. In yet another embodiment of the invention according to the first or second aspect, all reinforcement portions have the same shape and dimensions. In yet another embodiment of the invention according to the first or second aspect, the oblong through hole is elliptic, oval or race track-shaped. Short description of the figures

fig. 6 shows a fifth embodiment of a reinforcement element according to the first aspect of the invention.
Detailed description of preferred embodiments
Fig. 1 shows a first embodiment of a reinforcement element 1 according to the first aspect of the invention. The reinforcement element comprises a plane sheet- or plate-shaped body of a row of at five consecutively coupled reinforcement portions 1 a-1 e with waist portions 2a-2d there between. All reinforcement portions are provided with oblong through holes 3a-3e. The oblong through holes are elongated in the lengthwise direction of the row. The oblong through holes and the outer peripheries of all reinforcement portions have the same elliptical shape. The reinforcement portions may also be described as elongated or oblong rings. Each reinforcement portion has the same dimensions. Each of the waist portions 2a-2d has a smoothly curved periphery such that the elliptical reinforcement portions 1 a-1 e transcend to each other smoothly and that the outer periphery of the overall reinforcement element is smooth. Each waist portion has a smaller width than the peripheral width of the neighboring reinforcement portions (in a perpendicular direction relative the lengthwise direction of the row). The width of each waist portion is furthermore slightly smaller than the width of the through holes (in a perpendicular direction relative the lengthwise direction of the row). The fifth reinforcement portion 1 e has a peripheral width W corresponding to the elongation L of the oblong through hole 3a of the first reinforcement portion. The elongation L corresponds to the length of the oblong through hole 3a in the lengthwise direction of the row. Furthermore, the width (in a perpendicular direction relative the lengthwise direction of the row) of each oblong through hole 3a-3e is smaller than the peripheral width W.
Fig. 2 shows a second embodiment of a reinforcement element according to the first aspect of the invention which is similar to the first embodiment except for that only the first and fifth reinforcement portions 1 1 a, 1 1 e are elliptical, whereas the second, third and fourth reinforcement portions 1 1 b-1 1 d are ring- shaped, i.e. the through holes 13b-13d and the outer peripheries of the second, third and fourth reinforcement portions are circular.
Fig. 3 shows a third embodiment of a reinforcement element 21 according to the first aspect of the invention. The reinforcement element comprises a plane sheet- or plate-shaped body of a row of at five consecutively coupled reinforcement portions 21 a-21 e with waist portions 22a-22d there between. The first reinforcement portion 21 a is provided with an oblong through hole 23a. The oblong through hole 23a is elongated in the lengthwise direction of the row, but may, as illustrated by the dotted ellipses, be elongated in other directions, preferably in a non-perpendicular direction relative the lengthwise direction of the row. The outer peripheries of the first, second, third and fourth reinforcement portions 21 a-21 d are circular, whereas the outer periphery of the fifth reinforcement portion is elliptical. The second, third and fourth reinforcement portions 21 b-21 d have circular through holes 23b-23d. The fifth reinforcement portion 21 e does not have a through hole in this embodiment, but may have so in other embodiments. Each of the waist portions 22a-22d has a smoothly curved periphery such that the reinforcement portions 21 a- 21 e transcend to each other smoothly and that the outer periphery of the overall reinforcement element is smooth. Each waist portion has a smaller width than the peripheral width of the neighboring reinforcement portions (in a perpendicular direction relative the lengthwise direction of the row). The fifth reinforcement portion 21 e has a peripheral width W corresponding to the elongation L of the oblong through hole 23a of the first reinforcement portion. The elongation L corresponds to the length of the oblong through hole 23a in the lengthwise direction of the row. Furthermore, the short or non-elongated width of the oblong through hole 23a is smaller than the peripheral width W. Fig. 4 shows a fourth embodiment of a reinforcement element 31 according to the first aspect of the invention which is identical to the first embodiment, except for that it comprises a larger number of reinforcement portions. The reinforcement is shown bent into a circular shape, where the last
reinforcement portion 31 b of the row of reinforcement portions is locked within the through hole 32a of the first reinforcement portion 31 a. The peripheral width of the last reinforcement portion 31 b has a peripheral width
corresponding to the elongation of the through hole 32a of the first
reinforcement portion in the same manner as disclosed in figure 1 . The waist portion 33b between the last reinforcement portion 31 b and the preceding reinforcement portion 31 c has a smaller width than the peripheral width of the reinforcement portions 31 b, 31 c and also a slightly smaller width than the width of the through hole 33b (in a perpendicular direction relative the lengthwise direction of the row). Therefore, all the reinforcement portions of the reinforcement element may be arranged in a plane as shown in figure, also when the last reinforcement portion 31 b is locked within the through hole 32a.
Fig. 5 shows an embodiment of a reinforcement arrangement according to the second aspect of the invention. The reinforcement arrangement comprises first and second reinforcement elements 41 and 44 according to the first embodiment (not all reinforcement portions are shown). The first
reinforcement portion 44a of the second reinforcement element 44 is locked within the oblong through hole 42a of the first reinforcement portion 41 a of the first reinforcement element 41 . The waist portion 45a between the first reinforcement portion 44a of the second reinforcement element 44 and the preceding reinforcement portion 44b has a smaller width than the peripheral width of the reinforcement portions 44a, 44b and also a slightly smaller width than the width of the through hole 42a (in a perpendicular direction relative the lengthwise direction of the rows). Therefore, the first and second reinforcement elements may be arranged along a straight line, i.e. along a common lengthwise direction, as shown in figure, also when locked together. Fig. 6 shows a fifth embodiment of a reinforcement element 51 according to the first aspect of the invention which is similar to the third embodiment except for that all reinforcement portions have circular outer peripheries, and that all reinforcement portions have through holes. The second, third, fourth and fifth reinforcement elements have the same shape and dimensions. The fifth reinforcement portion 51 e has a peripheral width W corresponding to the elongation L of the oblong through hole 53a of the first reinforcement portion.
Although exemplary embodiments of the present invention have been shown and described, it will be apparent to the person skilled in the art that a number of changes and modifications, or alterations of the invention as described herein may be made. In particular, the number of reinforcement portions of the reinforcement elements shown in the figures are merely chosen for illustrative purposes. Thus, it is to be understood that the above description of the invention and the accompanying drawings are to be regarded as a non- limiting examples thereof and that the scope of the invention is defined in the appended patent claims.
