Abstract
The utility model discloses a steel fiber with a plurality of anchoring points, which comprises a middle connection segment. A fist anchoring segment which is in a first plane and protrudes out of the middle connection segment is arranged on both ends of the middle connection segment; a first anchoring end is connected with a second anchoring segment; an obtuse included angle is formed between the axial lines of the second anchoring segment and the first anchoring segment; the second anchoring segment is connected with a third anchoring segment; an included angle is formed between the axial lines of the third anchoring segment and the second anchoring segment; the third anchoring segment is in a second plane and protrudes out of the second anchoring segment. Three anchoring segments are arranged on both ends of the middle connection segment in the steel fiber to form three anchoring points so that bonding stress and anchoring force in concrete are used effectively and the bending resistance property and cracking resistance property of the concrete are improved. The steel fiber has good workability and no balling during the processes of construction stirring and spraying.
Description
Technical field
The utility model belongs to the attached material of building, is specifically related to the steel fibre in a kind of concrete.
Background technology
Steel fibre has been widely used in the concrete, to strengthen concrete fracture resistance and cracking performance.Existing steel fibre has two kinds of form of structure, a kind of is end hook shape and shield bell shape, the steel fibre two ends of these two kinds of structures respectively have only an anchoring section, promptly only form an anchor point, this steel fibre and concrete bond stress and anchored force are less, and be limited to increasing concrete fracture resistance and cracking performance.Existing a kind of ball trace type steel fibre patented product, it is the concavo-convex ball trace that distributes at the two ends of steel fibre principal piece, it is to form anchor point at the position of ball trace, promptly a ball trace position forms an anchor point, form a plurality of anchor points, just must establish a plurality of ball traces, and all in the same side of principal piece.Holding capacity is better in this plane like this, and the holding capacity in other planes is limited.
Summary of the invention
Purpose of the present utility model is to provide a kind of steel fibre with multi-anchor fixed point, to address the above problem.
The technical solution of the utility model is: the steel fibre with multi-anchor fixed point: it comprises middle connecting segment, first anchoring section that protrudes from middle connecting segment that all has in first plane is established at the two ends of middle connecting segment, what be connected with first anchored end has second anchoring section, the angle that has an obtuse angle between the axis of second anchoring section and first anchoring section, what be connected with second anchoring section has the 3rd anchoring section, have an angle between the axis of the 3rd anchoring section and second anchoring section, the 3rd anchoring section at the second plane convex for second anchoring section.
Described middle connecting segment cross section forms by circular cross-section is cold rolling.
Described first plane is vertical with second plane.
This steel fibre is provided with three anchoring sections separately at the two ends of middle connecting segment, forms three anchor points, and first anchor point and second anchor point have improved the supporting capacity of steel fibre in Different Plane not in same plane.Middle connecting segment has improved 10 by the tensile strength of cold rolling back steel fibre on raw-material intensity basis simultaneously.Bond stress and the anchored force of this steel fibre in concrete is fully used, and more helps improving concrete fracture resistance and cracking performance.This steel fibre the construction whipping process in and the construction course of injection in workability good, no conglomeration, steel fibre can be not stretching in concrete.
Description of drawings
The steel fibre master that Fig. 1 has multi-anchor fixed point looks schematic diagram.
Fig. 2 has the attached schematic diagram of looking of steel fibre of multi-anchor fixed point.
The specific embodiment
As shown in Figure 1, the cross section of steel fibre middle connecting segment 1 is flat straight shape, form by cold rolling by circular cross-section, establish at the two ends of middle connecting segment 1 all first anchoring section 2 that protrudes from middle connecting segment, be that vertical plane is connected or the inclined-plane connects between first anchoring section 2 and the middle connecting segment 1, present embodiment adopts the inclined-plane to connect 3 transition.The projection of first anchoring section 2 is at vertical plane.The cross section of first anchoring section 2 is circular.Have the angle at an obtuse angle between the axis that second anchoring section, 5, the second anchoring sections 5 and first anchoring section 2 are arranged that is connected with first anchoring section 2, angle is 120～150 °: the cross section of second anchoring section 5 is for circular; Have an angle between the axis that the 3rd anchoring section 6, the three anchoring sections 6 and second anchoring section 5 are arranged that is connected with second anchoring section 5, angle is 120～150 °.This angle can be acute angle, right angle or obtuse angle, adopts the obtuse angle in the present embodiment.This section is parallel with interlude.As shown in Figure 2, for second anchoring section, promptly for second anchoring section, the cross section of the 3rd anchoring section also is to form by circular cross-section is cold rolling to the 3rd anchoring section to the 3rd anchoring section at the horizontal plane convex at the second plane convex.Above-mentioned three anchoring sections can form five anchor points in concrete, promptly anchor point 7,8,9,10,11.
Claims (6)
1. steel fibre with multi-anchor fixed point, it comprises middle connecting segment, first anchoring section that protrudes from middle connecting segment that all has in first plane is established at the two ends that it is characterized in that middle connecting segment, what be connected with first anchored end has second anchoring section, the angle that has an obtuse angle between the axis of second anchoring section and first anchoring section, what be connected with second anchoring section has the 3rd anchoring section, have an angle between the axis of the 3rd anchoring section and second anchoring section, the 3rd anchoring section at the second plane convex for second anchoring section.
2. the steel fibre that has multi-anchor fixed point according to claim 1 is characterized in that between first anchoring section and the middle connecting segment it being that vertical plane is connected or the inclined-plane connects.
