Abstract
The utility model provides a steel fibre for ring shape concrete, it relates to the building steel field, concretely relates to ring shape steel fibre comprises ring shape mobile jib, anchor point, rib line and anticorrosive coating, and the equidistant several anchor point that is provided with on the ring shape mobile jib surface is provided with the rib line between two adjacent anchor points, surveys in the ring mobile jib and also sets up the rib line, and the surperficial cladding of ring shape mobile jib has the anticorrosive coating. After the technical scheme is adopted, the utility model discloses beneficial effect does: the composite reinforcing effect of the steel fiber on a two-dimensional coordinate is realized, the design is simple and novel, and the compressive strength, the bending resistance, the crack resistance and the agglomeration resistance of the concrete doped with the steel fiber are greatly improved compared with those of the traditional linear steel fiber.
Description
Technical Field
The utility model relates to a reinforcing concrete anti-fiber material who splits ability, concretely relates to ring shape steel fiber for concrete.
Background
At present, steel fibers used for concrete are linear fibers, namely a straight line, an arc line or a broken line, and the functions of the steel fibers are mainly embodied in that the toughness or the energy absorption capacity of the concrete is improved, the tensile limit or the tensile strength or the strain of the concrete is improved, and the capability of controlling cracks of the concrete is improved. However, the tensile stress to which the linear steel fibers are subjected is along the axial direction, and the region in which the tensile stress or the shear stress acts is also limited to the linear region in which the fibers are in contact with the concrete matrix, so that the linear steel fibers are easy to separate from or pull out of the concrete matrix under the action of higher tensile stress or shear stress, and have certain limitation, if the fibers can act together in 2 dimensions under the action of tensile stress or shear stress, the performance of the steel fibers for reinforcing the concrete matrix can be exerted to a greater extent. And the linear steel fiber is easy to agglomerate and is not easy to disperse in the using process due to the two protruding ends of the linear steel fiber, and the uniformity in the concrete body is poor. If the ring shape is closed, it becomes easier to disperse uniformly because it has no protruding portion.
Disclosure of Invention
An object of the utility model is to provide a ring shape steel fibre for concrete has improved the anti toughening performance that splits of one-dimensional linear steel fibre in the concrete to in use changes the homodisperse.
The utility model provides a ring shape steel fibre for concrete comprises ring shape mobile jib, first rib line, anchor point, second rib line and anticorrosive coating, and the interior survey evenly distributed of ring shape mobile jib has first rib line, and outside evenly distributed has the anchor point, is equipped with second rib line between two adjacent anchor points, and the surface coating of ring shape mobile jib has anticorrosive coating.
The utility model discloses in, ring shape mobile jib is the confined ring shape, and the material is the steel material, and the internal diameter is 10mm ~40mm, and thickness is 0.4~0.7mm, and the width is 0.8~2.0 mm.
The utility model discloses in, first rib line is long banding protruding helicitic texture, at the inboard equidistant setting of ring shape mobile jib.
The utility model discloses in, the anchor point is the protruding structure of square, at the equidistant setting in ring shape mobile jib outside.
The utility model discloses in, second rib line is rectangular form protruding helicitic texture.
The beneficial effects of the utility model reside in that: the utility model relates to a novelty compares in traditional linear fiber, and in use should not reunite, easy homodisperse, and single fibrous body can be when the concrete base member atress in the arbitrary direction performance at ring place anti effect of splitting, the ring shape fibre can form the hoop effect to the concrete simultaneously, has promoted the anti toughening performance that splits of fibre concrete greatly.
