Abstract

The utility model provides a prestressed steel wire, which is characterized in that the diameter phi of the steel wire ranges from 2.9mm to 6.00mm, three sides of the steel wire are provided with indentations along the radial direction, the indentations on the three sides form 120-degree angle mutually, an indentation line of the steel wire along the axial direction forms a reflex angle with the adjacent indentation line, the indentations are parallelograms, the depth of each indentation ranges from 0.03mm to 0.2mm, the length of each indentation ranges from 3mm to 5mm, and the pitch of each indentation ranges from 5.0mm to 8.5m. The prestressed steel wire has the advantages of capability of enhancing bond stress with concrete, high strength, capability of solving the problems of slipping and retraction of core wires and intermediate wires, high mechanical property and wide application range.

Description

A kind of compressor wire
Technical field
The utility model relates to a kind of building trade prestressing steel technical field, particularly relates to employed compressor wire in a kind of prestressed concrete member.
Background technology
Prestressed concrete member in the building trade in increasing mechanical properties such as member resistance to compression, antidetonation, mostly uses compressor wire or steel strand to make arrangement of reinforcement.The quality of the bond stress between tool arrangement of reinforcement and the concrete is the key factor of decision prestressed concrete member quality,
The prestressed concrete member of present technology adopts round wire or single rule deforming steel wire or has the steel strand that symmetrical indented wire is done or formed by the above steel wire system of twisting is prestressed concrete member adapted master muscle, there are the following problems: 1, the round wire surface is smooth, bond stress is less, 2, the steel strand that have the round wire system of twisting to form, only depend on the back pressure stress of the frictional force generation of the non-effective contact between the round wire to concrete component, very easily produce core silk limit portion slippage retraction, cause the minimizing of core silk stress or lose stress fully, restrict the quality and the life-span of prestressed concrete member, and reduced steel strand and concrete bond stress; 3, single rule deforming steel wire or the steel strand that have symmetrical indented wire or formed by the above steel wire system of twisting, and the bond stress between the concrete is less, especially the former stress is concentrated seriously, causes prestressed concrete member second-rate.
Summary of the invention
The purpose of this utility model is to provide a kind of enhancing and grip of concrete in order to overcome deficiency of the prior art, and the intensity height solves core silk and intermediate filament slippage retraction problems, and mechanical property is good, the compressor wire of applied range.
The technical scheme that the utility model adopted is: a kind of compressor wire, described steel wire diameter is φ 2.9mm-6.00mm and has indentation, described steel wire radially three has been worn indentation, three indentations are mutually 120 °, a described steel wire line of weakness in axial direction becomes dihedral with an adjacent line of weakness, and described indentation is a parallelogram, and width of nick is 0.03mm-0.2mm, indentation length is 3mm-5mm, and pitch of nick is 5.0mm-8.5mm.
The beneficial effects of the utility model are: increased steel strand and concrete bond stress, solved core silk and intermediate filament slippage retraction problems, kept steel strand good mechanical performance, improved the prestressed concrete member quality.

The specific embodiment
In order to further specify summary of the invention of the present utility model and characteristics, specify as follows in conjunction with the embodiments:
As shown in Figure 1 and Figure 2, steel wire 1 diameter described in the utility model is φ 2.9mm-6.00mm and has indentation 2, described steel wire 1 radially three has been worn indentation 2, three indentations 2 are mutually 120 °, described steel wire 1 line of weakness in axial direction becomes dihedral with an adjacent line of weakness, and described indentation 2 is a parallelogram, and indentation 2 degree of depth are 0.03mm-0.2mm, indentation 2 length are 3mm-5mm, and indentation 2 pitches are 5.0mm-8.5mm.
The above only is preferred embodiment of the present utility model, is not scope of the present utility model is limited, and various distortion and improvement that those of ordinary skills make skill flitch case of the present utility model all should fall in the utility model protection domain.
