Description
Technical field
A kind of abnormity concrete trilateral of the present invention terminal steel fiber, relates to engineering construction field.
Background technology
Steel Fiber Reinforced Concrete is with concrete materials such as grout, sand, aggregates for matrix, the matrix material that mixing of steel fiber forms as strongthener.The expansion that tensile strength is high, limit elongation is large, interface cohesive force is strong steel fiber effectively can limit tiny crack in external load function lower substrate is mixed in matrix.On the one hand, before matrix breakdown, matrix and steel fiber bear external load jointly, and matrix is main recipient; On the other hand, when after MATRIX CRACKING, the fiber across crack becomes the main recipient of external load.
At present, along with development and the going deep into concrete research of foundation works construction, 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 existed is: steel fiber and concrete bonding effect is undesirable, anchor force is poor, and performance is difficult to meet the requirement that engineering construction improves day by day.The solution key of the problems referred to above is the steel fiber designing highly effective.
Summary of the invention
The invention 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 present invention takes is: a kind of abnormity concrete trilateral terminal steel fiber, comprise by-level section, by-level section two ends connect the first tilting section, the second tilting section respectively, described first tilting section, the second tilting section connect the first horizontal section, the second horizontal section respectively, the end of described first horizontal section, the second horizontal section connects trilateral terminal, and described trilateral terminal is provided with indenture.
Staggeredly on the upper surface of described by-level section, lower surface be distributed with indenture.
Described first tilting section, the second tilting section are provided with indenture.
Described 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.
Three limits of described trilateral terminal are equipped with indenture.
Described horizontal section, tilting section, trilateral terminal comprise in carbon steel fibre, steel alloy fiber or Stainless Steel Fibre one or several.
The diameter of described horizontal section, tilting section is 1mm ~ 2mm.
A kind of abnormity concrete trilateral of the present invention 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 to increase significantly.
