Abstract
The utility model discloses spiral-type steel fiber with a special-shaped section. The whole appearance of the steel fiber is linear, the axial direction is spiral-type, and a transverse section is a non-circular plane. Compared with common steel fiber, the special-shaped section enlarges the contact surface of the steel fiber and concretes, and the spiral-type feature of the axial direction obviously improves bounding and anchoring property of the steel fiber to the concretes. Therefore, anti-bending property and toughness of the concretes are obviously improved, and durability of a concrete structure is improved. The linear whole appearance is good in workability during stirring and construction, has no agglomeration phenomenon, and has good practical use property.
Description
Technical field
The utility model relates to a kind of steel fiber, more specifically relate to a kind of can be dispersed in the concrete and strengthen, the special crosssection spiral steel fiber of toughness reinforcing concrete material.In International Patent Classification (IPC), should belong to the E04C group.
Background technology
Weakness such as Steel Fiber Reinforced Concrete is increasingly extensive in application in engineering such as road, bridge, tunnel, water conservancy project, airports as a kind of important civil engineering material, and steel fiber and concrete bond-anchorage intensity are low, the steel fiber kind aging, effect is single are difficult to satisfy the requirements at the higher level of modern architecture to concrete material.
Summary of the invention
The purpose of the utility model is to provide a kind of special crosssection spiral steel fiber, and itself and concrete bonding strength and anchorage effect obviously improve, and can significantly improve concrete toughness, reaches the purpose that promotes concrete over-all properties.
The said special crosssection spiral of the utility model steel fiber overall appearance type linearly, it axially is a spiral, the non-circular plane of xsect is preferably trilateral, these three sides of a triangle are the circular arc limit.
The diameter of the said special crosssection spiral of the utility model steel fiber is 0.5～0.9mm, and nominal length is 25～50mm, and length-to-diameter ratio is 40～80.
The utlity model has following beneficial effect:
1, the main part of the utility model type linearly, mix concrete after, good dispersion property stirs, does not have clustering phenomena in the construction process, shows the favorable actual application performance.
2, the utility model is spiral axially; Make whole steel fiber good adhesive property to be arranged with concrete; Greatly improved itself and concrete bond stress, the power consumption that steel fiber is extracted from concrete substrate increases, and the toughness of Steel Fiber Reinforced Concrete significantly strengthens.
3, the steel fiber profiled cross-section has increased the specific surface area of steel fiber, with the expansion of concrete binding area, can suppress and slow down the formation and the development of distress in concrete effectively, thereby improve concrete resistance to cleavage.
In a word, the utlity model has good with the concrete binding performance, the cracking resistance toughening effect is good, be easy to outstanding advantage such as construction, and is remarkable to concrete enhancing, toughening effect, effectively improves the weather resistance of concrete structure, prolongs the work-ing life of buildings.

Fig. 2 looks enlarged view for the transversal face of Fig. 1.
Embodiment
The steel wire of rounded section is designed to the punching block of special crosssection through the traction entering of traction type equipment; Through pushing, be drawn into the steel wire of special crosssection; Through the spiral forming device steel wire is radially rotated along its axle center again; Reverse and form the spirrillum steel wire, cut off obtaining the special crosssection spiral steel fiber of length range at last by demand at 25～50mm.
Claims (4)
1. special crosssection spiral steel fiber, the overall appearance that it is characterized in that steel fiber is type linearly, and it axially is a spiral.
2. special crosssection spiral steel fiber according to claim 1 is characterized in that the steel fiber xsect is non-circular plane.
3. special crosssection spiral steel fiber according to claim 2 is characterized in that the steel fiber xsect is a trilateral, and these three sides of a triangle are the circular arc limit.
4. according to claim 1 or 2 or 3 described special crosssection spiral steel fibers, the equivalent diameter that it is characterized in that steel fiber is 0.5～0.9mm, and nominal length is 25～50mm, and length-to-diameter ratio is 40～80.
