Abstract
The utility model relates to a reinforced fiber structure for concrete. The reinforced fiber structure for concrete is a high polymer fiber which is provided with a rough surface. A cross-sectional shape of the reinforced fiber structure for concrete can be a six-leaf shape or a five-leaf shape. A profile shape can be a wave shape or a saw-tooth shape. The diameter of the fiber is between 0.5 mm and 1.0 mm. The length of the fiber is between 40 mm and 75 mm. The fiber structure has high tensile strength, low elastic modulus, strong acidity and alkalinity resistance, and light specific gravity. The reinforced fiber structure for concrete is used for controlling cracks of cement concrete in a construction work, and the toughness and shock resistance of the cement concrete in the construction work can be raised. Anti checking and reinforced actions of a traditional steel reinforcement and a steel fiber can be replaced. Construction cost can be more economic. Operation can save time conveniently. The utility model is a novel reinforced material for concrete with extensive use prospect. The utility model can be used for replacing the toughness of fiber reinforced concrete and can meet the needs of the combination property of construction work quality.
Description
Technical field
The utility model relates to the improvement of reinforcing rib structure in the concrete, belongs to International Classification of Patents C04B16/06 " fibrous reinforcement filler in mortar, the concrete " technical field.
Background technology
The construction work cement concrete is easy to cracking, infiltration under different temperature climate change conditions, and under the use of heavy loading, ftracture easily, fracture, be influence construction quality and work-ing life long-standing for a long time.Many construction project experts improve concrete tenacity for solving concrete cracking resistance, impervious, anti-folding, have adopted reinforcing mat, steel fibre web, glass fibre to replenish as anticracking material, are applied to concrete.Be to use man-hour many but do one like this, cumbersome, the 2nd, the contact of acid-basicity gets rusty easily, and influences the engineering life-span.The 3rd, price is expensive, and it is big to increase construction cost.Also have glass fiber applications in concrete enhancing, the one, resistance to acids and bases not, the 2nd, rupture easily when stirring, the 3rd, the tension brute force is low, therefore is difficult to popularize in an all-round way in engineering construction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of tenacity and shock resistance of can improving in the engineered cementitious concrete is provided---be used for concrete fortifying fibre structure.
The technical solution of the utility model is as follows.
A kind ofly be used for concrete fortifying fibre structure, for a kind of high-polymer fiber, have uneven surface, its shape of cross section can be sexfoil or five leaf, and its outer shape can be undaform or zig-zag; The diameter of fiber is between 0.5mm-1.0mm, and the length of fiber is 40mm-75mm.
Concrete reinforced fiber structure of the present utility model, the tensile strength height of fiber, Young's modulus is low, and anti acid alkali performance is strong, light specific gravity.Be applied to construction work cement concrete control crack, improve its tenacity and shock resistance, the anticracking and the enhancement of alternative traditional reinforcing bar, steel fiber, its construction cost is more economically.Using operation to save time conveniently, is that the concrete with wide application prospect strengthens type material.The toughness that it replaces fiber reinforced concrete can satisfy construction project quality comprehensive performance demands.
Description of drawings
Fig. 1 is a kind of embodiment of the utility model concrete reinforced fiber structure: the cross section is the synoptic diagram of sexfoil;
Fig. 2 is another kind of embodiment: the cross section is five leaf synoptic diagram;
Fig. 3 is a kind of embodiment of profile: profile is corrugated synoptic diagram;
Fig. 4 is the another kind of embodiment of profile: profile is zigzag synoptic diagram.
Embodiment
The main raw material(s) of fortifying fibre of the present utility model be polypropylene and, adding the minor amounts of copolymerized thing mixes, be shaped through screw rod melt extruded to special-shaped spray silk, again through too much times, repeatedly stretching, after being rolled into zig-zag, undaform, through cooling and shaping, drying, cut into needed length, use the plastic film bag packaging final prod again.
Fiber truncation surface abnormal shape is a sexfoil or five leaf, and outer shape can be undaform or zig-zag, and assembly can be carried out in outer shape and cross section.
The diameter of fiber is the arbitrary value between the 0.5mm-1.0mm, and staple length is 40-75mm, and preferred embodiment is 40mm, 50mm, 65mm, 75mm.
The key technical indexes of fiber: density is 0.91g/cm, and tensile strength is greater than 500Mpa, and Young's modulus is 3000-3500Mpa, and unit elongation is 15-20%, and fusing point is 165 ℃.
This fibrous texture has the profile of reinforcing bar, steel fiber, possesses the function of reinforcing bar, steel fiber, has the advantage of synthetic soft fibers again.The material of this fibrous texture is widely used in cement highway, motorway, airfield runway, hardstand, cement concrete precast construction part, plate, pipeline; various tunnels sprayed concrete building, roof, vault, parking lot, terminal of containers and all kinds of concrete construction engineering.
Volume and using method: the minimum volume in every cube of concrete is 2.5 kilograms, and maximum doping quantity is 5 kilograms, can use common concrete batch plant, uses more convenient.When concrete normally stirs, add fiber, proper extension 2-3 minute, just can make fiber be evenly distributed on concrete each corner.
Show through concrete experiments: as 2.5 kilograms of fibers of every cube of blending, its shock resistance can improve 3.5 times, and plastic shrinkage cracks can reduce 10.5 times, and residual intensity can reach 120 pounds, improves more than 10 times.
