Abstract
The utility model relates to wire fibre for concrete, which is designed into waviness. The axial length of wire is 20-50 millimeters, equivalent diameter is from 0.3 millimeters to 0.8 millimeters, slenderness ratio is within 40-100, waviness height is from 1.5 times to 5 times longer than the equivalent diameter, and cross-sectional shape is a circle or a quadrangle or other irregular shapes. After the concrete is mixed in the wire fibre which is made according to the utility model, the cohesive force of the wire and cement enlarges, and the tensile strength, the compression strength, the breaking strength, the shock strength and shearing strength of concrete work is obviously enhanced. Besides, compared with a spiral shape, the waviness has a simple shape, and hence, the utility model is difficult to entangle and cake, but is easy to mix.
Description
The utility model relates to a kind of improved concrete steel wire fibre that is used for, and specifically a kind ofly dopes the steel wire fibre of thing as concrete, belongs to constructional materials articles for use technical field.
In order to increase the intensity of concrete structure, reinforcing bar is set in concrete structure normally.Make the concrete structure of aggregate with reinforcing bar, the intensity of aspects such as its bulk strength such as tension, resistance to compression, shearing resistance improves greatly, and still, the intensity of aspects such as the cracking resistance on this steel concrete top layer, shock resistance is still lower.There is the human steel wire fibre to add in the concrete, makes the surface strength of steel concrete obtain reinforcement.Yet further test finds that when this concrete was damaged, steel wire fibre was to extract, rather than breaks from matrix.This phenomenon explanation, steel wire fibre depends on the adhesive property of steel fibre and matrix to concrete humidification.When adopting the spirality steel wire fibre, though can improve adhesive property, conglomeration easily again with cement, the stirring of sandstone material the time.This also illustrates, this cross section is garden shape, axially for straight shape, arc or spiral steel wire fibre also have certain disadvantage, is necessary to design a kind of more rational steel wire fibre shape, strengthens the adhesive property of steel wire fibre and concrete substrate.
The purpose of this utility model provides a kind of improved concrete steel wire fibre, and this fiber should have and the better binding ability of concrete base-material, and in use has the characteristics that are not easy to tangle conglomeration.
The purpose of this utility model is achieved in that
A kind ofly be used for concrete steel wire fibre, the equivalent diameter of steel wire fibre is between the 0.3-0.8 millimeter, and draw ratio is in the 40-100 scope, axial length is the 20-50 millimeter, its basic improvements are that described steel wire fibre is corrugated, and the ripple height is 1.5-5 a times of equivalent diameter.
Above-mentioned concrete steel wire fibre, the ripple number 1-5 of steel wire fibre.
Above-mentioned concrete steel wire fibre, the cross section of steel wire fibre are that garden shape, quadrangle or other are irregularly shaped.
Above-mentioned concrete steel wire fibre in order to improve corrosion resisting property, can adopt sheet material or the wire rod of stainless steel Q195, Q235 and 0.8F, 0.8AL etc. to make.
The steel wire fibre of making according to the utility model because its axial shape is a corrugated, strengthens the adhesive property of itself and concrete base-material greatly, and the cross section is quadrangle or other irregular shape, has further strengthened its performance again.And be tetragonal steel wire fibre for the cross section, they generally are to adopt steel sheet to shear to form, corner angle that produce in shear history and burr have improved its adhesion stress again again, and tension, resistance to compression, cracking resistance, shock resistance, the shear strength of concrete work are strengthened.If adopt stainless steel,, thereby make a kind of higher intensity of the long-term maintenance of steel wire fibre then because of having prevented corrosion.In addition, because corrugated than helical form, shape is more simple, therefore is difficult for tangling conglomeration, is easier to dope.
Fig. 1 is a shape schematic diagram of the present utility model.
An embodiment of the present utility model as shown in Figure 1, the length of steel wire fibre is 30 millimeters, cross sectional shape is circular, diameter is 0.7 millimeter, and its axial shape is corrugated, and the ripple number is two, so-called ripple is to refer to comprise a crest and a trough.Ripple height (distance that refers to peak to peak is high) is 1.5 times of diameter, and its material adopts 0.8AL to make.
Another embodiment of the present utility model is, the length of steel wire fibre is 30 millimeters, the cross section is a rectangle, long 0.8 millimeter in cross section, wide 0.5 millimeter, equivalent diameter (so-called equivalent diameter is meant the diameter of a circle that equates with described section area) is 0.71 millimeter, and its axial shape is corrugated, the ripple height is 1 times of its cross section equivalent diameter, adopts the punching out of Q235 stainless steel materials to form.
More than the dope amount of two kinds of steel wire fibres in concrete represent with volume, be 1.5%, base-material is common 525 cement, sample dimensions is the 150*150*150 millimeter.After tested, record this ripple type steel wire fibre concrete sample that is added with after 28 days, than the tensile strength raising 38-47% of the concrete sample that does not add steel wire fibre, compressive strength improves 15-39.7%.Compare with the concrete sample that dashes with straight shape steel wire fibre, tensile strength improves 6-10%, and compressive strength improves 3-7%.Through explosion bulge test, with the fried bag test of same intensity, be added with the fried hole on the concrete floor of this corrugated steel wire fibre, more shallow than the fried hole of the concrete floor that does not add steel wire fibre, for its 1/3rd.As seen, it has improved the cracking resistance and the shock-resistant ability on top layer really greatly.This corrugated steel wire fibre can be widely used in the road surface of building highway, bridge, airfield runway, ship lock, sluicing gallery, dam, culvert, give in the concrete of system stake and explosion-proof engineering etc.
