Abstract
The utility model discloses polypropylene fiber filaments and bunched twisting synthetic crude fibers made of the same, which are characterized in that three quadrilaterals arranged in parallel form a longitudinal section of each polypropylene fiber filament, the edges of each quadrangle are in inwards arced shapes; and adjacent quadrilaterals are connected into a whole. 20 to 30 groups of the polypropylene fiber filaments can be manufactured into a bunch of twisting synthetic crude fibers by means of twisted forming. The polypropylene fiber filaments and the bunched twisting synthetic crude fibers compensate the shortcomings of traditional engineering fibers, not only have enhanced effect of steel fibers to concrete, but also have anti-cracking and enhanced toughness effects, simultaneously have the advantages of corrosion resistance and long service life due to the characteristics of high polymer materials of the polypropylene fiber filaments.
Description
One, technical field
The utility model belongs to a kind of concrete anticracking strongthener, being mainly used in admixture is mixed in the coarse aggregate cement concrete, homodisperse and with aggregate mechanism enhancing concrete the combine density of back by reinforcement of combining closely, significantly strengthen its intensity in the concrete initial set phase, prevent the formation of fine cracks and the extension of reflection crack at its freezing period and normal usage period, and can significantly improve concrete impelling strength, thereby prolong concrete normal work-ing life.
Two, background technology
Domestic steel fiber is mainly used in concrete enhancing since the eighties is promoted fibrous concrete mid-term, easily gets rusty but exist, and stirs and carries difficulty big, and exposing surface is drawn shortcomings such as damage to outside things easily; Other synthon are mainly used in concrete cracking resistance, and because of fineness is little, equivalent diameter is 0.02-0.01mm only, can only stop the formation of concrete microfracture, work hardly after concrete setting.
Along with the technical progress of domestic construction industry and the popularization of fibrous concrete standard, adding of fiber strengthens the basic way that anti-cracking and seepage control has become field of civil engineering in concrete, and the functional limitation of conventional products applying of fiber product.
Summary of the invention
The utility model purpose just is defective according to above-mentioned prior art a kind of polypropylene fibre monofilament is provided and by its pencil of making synthetic robust fibre that is twisted together.
Its technical solution is as follows: polypropylene fibre monofilament, the profile that it is characterized in that above-mentioned polypropylene fibre monofilament are three tetragons of arranging side by side, and above-mentioned tetragonal limit is the arc of indent, and adjacent tetragon is connected to each other to one.
Organize above-mentioned polypropylene fibre monofilament by 20-30 and after twisting moulding, can be made into a branch of synthetic robust fibre that is twisted together.
The utility model has remedied the deficiency of traditional technical fiber, and it had both had steel fiber to concrete reinforced effects, has anticracking again and strengthens the flexible effect, and because of the material behavior of its high molecular polymer, it has corrosion-resistant, the advantage of long service life simultaneously.
Three, description of drawings
Figure is the sectional view of the utility model fibre single thread.
Four, embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
Polypropylene fibre monofilament cross-sectional shape of the present utility model as shown in the figure, it comprises three tetragons of arranging side by side 1, above-mentioned tetragonal limit is the arc of indent, is connected as one by muscle 2 between adjacent tetragon.This product passes through high molecular polymer mixing extrusion moulding work in-process such as polypropylene,, properties-correcting agent painted by adding makes its color match with concrete, technical feature is fit to concrete and strengthens requirement, and by special distortion moulding and setting process, and then cut-out is packaged as finished product.
The above-mentioned polypropylene fibre of 20-30 root can be made into the be twisted together robust fibre of structure of cable shape, and dense structure is easy to packing and stores, and the cross section of its monofilament is flat concave shape, and three and together, increased and concrete bonded bond stress.In the concrete whipping process, tear the part of its connecting portion, can increase the crude degree in the monomeric surface of fiber, make its with concrete combine more firm.
Its equivalent diameter is 0.3-0.4 millimeter (a monomer diameter), between steel fiber (0.8-1.2 millimeter) and plastics synthon (0.02-0.1 millimeter), when concrete is played the cracking resistance effect, significant enhancing and toughening effect are arranged again, thereby improved concrete over-all properties.
Claims (3)
1. polypropylene fibre monofilament is characterized in that: the profile of described polypropylene fibre monofilament is three tetragons of arranging side by side, the arc that above-mentioned tetragonal every limit is an indent, and adjacent tetragon is connected to each other to one.
2. the pencil synthetic robust fibre that is twisted together is characterized in that: it is twisted together after through the distortion moulding by many groups of polypropylene fibre monofilament as claimed in claim 1 and makes.
3. the pencil according to claim 2 synthetic robust fibre that is twisted together is characterized in that: it is to be twisted together by 20-30 group polypropylene fibre monofilament to make.
