Abstract
The invention relates steel fibers, specifically to a flat-rolled drum shaped cross section spiral steel fiber. The invention solves the poor manufacturability problem in current the spiral steel fiber batch production. The flat-rolled drum shaped cross section spiral steel fiber includes a steel fiber body, the cross section of which is flat drum shaped cross section and the side of which is a spiral side. The flat-rolled drum shaped cross section spiral steel fiber concrete made from the flat-rolled drum shaped cross section spiral steel fiber provided in the invention is suitable for building construction.
Description
Technical field
The present invention relates to steel fiber, specifically is a kind of draw down cydariform cross section screw steel fiber.
Background technology
Steel fiber is the concrete reinforced material that the world today generally adopts.In normal concrete, mix random steel fiber, promptly form Steel Fiber Reinforced Concrete to distribution.Disorderly the expansion of inside concrete microfracture and the formation of macroscopic fracture be can effectively hinder, thereby concrete tension, bending resistance, shock resistance and anti-fatigue performance improved significantly to the steel fiber that distributes.Steel fiber is divided into because of its shape is different: straight shape steel fiber, pressure prismatic steel fiber, waveform steel fiber, crotch shape steel fiber, big capitiform steel fiber, two oar shape steel fiber, spiral steel fiber etc.In above-mentioned various Steel Fiber Reinforced Concretes, the spiral steel fiber concrete has typical strain hardening and compound crackle characteristic because of it, and excellent performance, application prospect are the most wide.Yet practice shows that existing spiral steel fiber is limit because of himself structure, and the problem of ubiquity mass production processes poor (promptly being difficult to produce in batches) causes it to be difficult to widespread adoption.Be necessary to invent a kind of brand-new spiral steel fiber, to solve the problem of existing spiral steel fiber mass production processes difference for this reason.
Summary of the invention
The present invention provides a kind of draw down cydariform cross section screw steel fiber in order to solve the problem of existing spiral steel fiber mass production processes difference.
The present invention adopts following technical scheme to realize: draw down cydariform cross section screw steel fiber comprises the steel fiber body; The cross section of steel fiber body is flat cydariform cross section; The side of steel fiber body is the volution side.
The length of described steel fiber body is 30-50mm.
The lateral pitch of described volution is 3-6mm.
Compare with existing spiral steel fiber, draw down cydariform cross section screw steel fiber of the present invention has adopted flat cydariform cross section, and every structural parameter have been carried out brand-new design, thereby it is easier to produce in batches, effectively improve mass production processes thus, effectively made things convenient for its widespread adoption.
The present invention is rational in infrastructure, design is ingenious, efficiently solve the problem of existing spiral steel fiber mass production processes difference, the draw down cydariform cross section screw steel fiber concrete that adopts draw down cydariform cross section screw steel fiber of the present invention to make is applicable to building operation.
