Description
Technical field
A kind of abnormity concrete trilateral of the utility model terminal steel fiber, relates to engineering construction field.
Background technology
Steel Fiber Reinforced Concrete is take concrete materials such as grout, sand, aggregates as matrix, the matrix material that mixing of steel fiber forms as strongthener.In matrix, mix tensile strength is high, limit elongation is large, interface cohesive force is strong steel fiber and can effectively limit the expansion of tiny crack in external load function lower substrate.On the one hand, before matrix breakdown, matrix and steel fiber bear external load jointly, and matrix is mainly to hold receptor; On the other hand, when after MATRIX CRACKING, what across the fiber in crack, become external load mainly holds receptor.
At present, along with the development of foundation works construction with to the going deep into of concrete research, Steel Fiber Reinforced Concrete is widely used.Because concrete steel kinds of fibers mainly contains: shear model steel fiber, undaform steel fiber, flat type steel fiber, steel wire end hook type steel fibers etc., the main drawback existing is: steel fiber and concrete bonding effect is undesirable, anchor force is poor, performance is difficult to meet the requirement that engineering construction improves day by day.The solution key of the problems referred to above is to design the steel fiber of highly effective.
Summary of the invention
The utility model provides a kind of abnormity concrete trilateral terminal steel fiber, have specified shape, can be uniformly distributed in randomly in concrete, to increase concrete strength.
The technical scheme that the utility model is taked is: a kind of abnormity concrete trilateral terminal steel fiber, comprise by-level section, by-level section two ends connect respectively the first tilting section, the second tilting section, described the first tilting section, the second tilting section connect respectively the first horizontal section, the second horizontal section, the end of described the first horizontal section, the second horizontal section connects trilateral terminal, and described trilateral terminal is provided with indenture.
The staggered indenture that is distributed with on the upper surface of described by-level section, lower surface.
Described the first tilting section, the second tilting section are provided with indenture.
Described the first tilting section, the second tilting section and the first horizontal section, the connected node position that the second horizontal section is corresponding are provided with indenture.
Described by-level section is connected and composed by two joint symmetric sections.
On three limits of described trilateral terminal, be equipped with indenture.
Described horizontal section, tilting section, trilateral terminal comprise one or several in carbon steel fibre, steel alloy fiber or Stainless Steel Fibre.
The diameter of described horizontal section, tilting section is 1mm ~ 2mm.
A kind of abnormity concrete trilateral of the utility model terminal steel fiber, steel fiber outside surface indenture can strengthen the bond-anchorage effect of steel fiber and concrete substrate.Described horizontal section, tilting section, trilateral terminal adopt carbon steel fibre, steel alloy fiber or Stainless Steel Fibre to be made.Its ultimate compression strength, ultimate bending strength, first crack strength, all increase significantly.
