Description

The invention relates to cable production and can be used in the production of tensile and embedded reinforcement intended for reinforcing monolithic structures and other concrete products.

Known reinforcing seven-wire rope according to GOST R 53772-2010, consisting of a central wire with a smooth surface and six wires with a smooth surface of the outer layer, twisted in a spiral. The disadvantage of this design is the relatively low adhesion to concrete. This factor is due to the low adhesion of concrete to the smooth surface of the wires, as well as the small size of the gaps between the circumference described around the section of the rope and the surface of the outer wires, which does not leave space for the formation of strong concrete crests under the generatrix of the rope and, in addition, the small inclination of these gaps to the axis of the rope . In combination with a smooth surface of the wires, this provokes the effect of screwing the rope into concrete on its own print.

Known reinforcing seven-wire rope according to patent DE 1659265, in which the wires have an additional periodic profiling in the form of protrusions and troughs, covering on three sides the entire surface of the grafting wires. This design of the rope provides a higher adhesion of the surface of the wires to concrete. The known rope has an additional mechanical engagement in the direction of screwing, however, in general it does not provide high adhesion to concrete due to narrow gaps between the circumference described around the section of the rope and the surface of the outer wires, which do not leave space for the formation of strong concrete crests under the generatrix of the rope. Another disadvantage of the known reinforcing rope is the reduction of endurance and relaxation resistance relative to a similar rope of smooth wires. It is due to the fact that the periodic profile forms numerous stress concentrators, which themselves reduce the mechanical properties, and, in addition, the periodic profile on the contacting surfaces determines the point contact between adjacent wires, which further enhances the stress concentration and also reduces the relaxation resistance - due to the local introduction of adjacent wires into each other at the contact points and the resulting displacement by a smaller laying radius and a direct increase in the length of Oloka, leading to an increase in length of the rope during operation in the constructions, and, consequently, reduce the pretension.

The closest analogue of the rope according to the present invention is the reinforcing rope according to the patent RU 2431024, containing the Central wire and wound around it helix wound wires with a periodic profile. The periodic profile is made in the form of inclined protrusions above the generatrix of the pressed surface of the rope, and the surface sections of the wires in contact with other wires are made in the form of spirally arranged flat platforms. A periodic profile is applied to the outer portion of the surface of the grading wires, and the gaps between the circumference described around the cross-section of the rope and the surface of the outer wires are larger than the gaps in the round wire rope due to the cross-sectional shape of the outer wires and the arrangement of the wires so that the contour connecting tangentially the outer sections of the midwire wires were close to a triangle with rounded corners.

The known rope has high adhesion due to the large gaps between the circumference described around the rope section and the surface of the outer wires, leaving space for the formation of strong concrete crests under the rope generatrix, a large enveloping contour and mechanical engagement in the screwing direction, and also has increased endurance relative to the previous considered analogue due to surface contact between the wires, fewer elements of the periodic profile and their location only on the outer surface of the rope and above the plastically compressed surface, which reduces the stress concentration during application.

A disadvantage of the known construction of the rope is the presence of stress concentrators in the form of protrusions of a periodic profile on all grafting wires. These stress concentrators significantly reduce the properties of reinforced structures at critical loads. In addition, the implementation of periodic profiling in the form of uncompressed protrusions above the crimped surface of the grafting wires leads to inhomogeneous length properties of the crimped and uncompressed surface sections. It also generates intense tensile stresses at the boundary between the crimped and uncompressed sections of the rope, in particular on the transverse surfaces of the periodic profile, which does not allow for maximum endurance and relaxation resistance.

A known method of manufacturing a reinforcing rope according to the patent RU 2431024, including the manufacture of round wires, twisting the wires into a rope of shaped spiral section and plastic crimping of the rope with simultaneous drawing of a periodic profile by deformation directly in the center of the winding along the outer surface of the inoculation wires in the shaped roller gauge with inclined rollers .

The disadvantage of this method is the inevitable formation of stress concentrators when applying a periodic profile in the form of protrusions above the crimped surface, which reduces the endurance of the manufactured rope. In addition, when compressing the surface and simultaneously applying a periodic profile with one roller on wires located at significantly different distances from the axis of the rope, the wires move relative to the surface of the roller at different speeds. In this case, defects arise in the form of “smeared” and “torn” sections of the profile, which increase the stress concentration. Another disadvantage of this method is the lack of thermomechanical processing, which further increases the operational characteristics of the rope.

The objective of the invention is to develop a reinforcing rope and a method for its manufacture, due to which the rope has increased endurance with a reduced number of stress concentrators in the wires and at the same time high adhesion to concrete both in the direction of longitudinal movement and in the direction of screwing.

This problem is solved in that the reinforcing rope consists of a central wire and helically wound around it in two concentric layers of grafting wires, each grafting wire has a surface area that is part of the outer surface of the rope, and each grafting wire of the outer layer is located in the groove between the two adjacent inoculation wires of the inner layer, and its surface is from the surface of the nearest inoculation wire of the outer layer at a distance of not less than half of its own radius of a cross-sectional size, while on each side of the surface of adjacent wires facing each other there are continuous spiral faces along the length, and the surface area of each of the grafting wires of the outer layer facing the outer surface of the rope has at least one crimped part, continuous along the entire length specified wires.

In this case, the term “continuous along the length of spiral faces” means surface areas of the central and grafting wires located on their surface in a spiral with a step equal to the pitch of the twist of the rope, and having borders visible to the naked eye with the rest of the surface of these wires, the transverse generatrix of these sections represents a straight line or arc with a radius of curvature not less than twice the radius of curvature of the remaining sections of the surface.

The execution of the rope in two concentric layers and the location of the winding wires of the outer layer with a considerable distance between them forms a pronounced, but at the same time smoothly changing surface profile of the rope, leaving gaps for the formation of massive and strong concrete crests under the circumference described around the section of the rope. The presence of continuous lengths of crimped parts on the outer surface ensures uniformity along the length of the mechanical properties of the rope and the absence of pronounced stress concentrators. The deep and extended protrusions of the profile allow the formation of massive crests of concrete under the generatrix of the rope, which ensures high adhesion to concrete in the longitudinal direction. The location of the outer layer winding wires in the grooves between the internal layer winding wires and the presence of spiral faces at the contact points of adjacent wires ensures reliable fixation of each wire of the rope in a predetermined position.

In addition, the reinforcing rope can be made in such a way that the surface section of at least one inoculation wire of the inner layer, which is part of the outer surface of the rope, has at least one crimped part, continuous along the entire length of the specified wire. This design increases the degree of compression of the grading wires of the inner layer and the central wire, which allows to increase the width of the spiral faces on them and, thus, to ensure the most reliable fixation of the wires in the structure of the rope.

In this case, the compressed parts of the surface of the midwire wires on the outer surface of the rope can be made rectilinear in cross section. This design is the most technologically advanced in production and when fixing the rope with clamps, it is also most effective when using reinforcing ropes in concrete with inert aggregates of a large fraction.

In addition, the compressed parts of the surface of the midwire wires on the outer surface of the rope can be made convex or concave in cross section. This design allows you to increase the contact surface of the reinforcing rope with concrete and thereby increase the adhesion and friction adhesion in concrete with inert aggregates of fine fraction.

Also, the reinforcing rope can be made in such a way that the compressed part of the surface of the at least one grafting wire has a periodic profile, which is fragments of the compressed part of the surface, having a generatrix different from the rest of the compressed part of this surface. This design is effective for conditions of increased vibration load on the reinforcement, when to prevent the screwing-in effect, mechanical coupling of the reinforcement with concrete in the screwing direction is necessary.

In addition, the reinforcing rope can be made so that the outer surface of the rope, including crimped parts, has a roughness exceeding the roughness of the surface of the spiral faces by at least 1 class. This design provides increased, relative to the original parts pressed in the roller gauge, adhesion to concrete, as well as reducing and equalizing residual stresses on the outer surface of the rope and in the surface layer of metal.

Also, the reinforcing rope may have an anti-corrosion coating on the wires. Corrosion-resistant coating can be made of a material, the main component of which is zinc. This design is effective for use in reinforced concrete structures that are regularly exposed to water, salt and other substances that contribute to corrosion.

According to one design variant, the reinforcing rope can be arranged in such a way that the inner layer consists of six inoculation wires, and the outer layer consists of three inoculation wires located at regular intervals from each other. In other embodiments, the reinforcing rope may have six inoculation wires in the inner layer, two or six inoculation wires in the outer layer, eight inoculation wires in the inner layer, and two, four or eight inoculation wires, or nine inoculation wires in the inner layer a layer and three or six inoculation wires in the outer layer. Rope design options allow you to implement different ratios of absolute and specific strength characteristics of the rope, as well as various ratios of strength characteristics and adhesion to concrete.

This problem is also solved by the fact that in the method of manufacturing the reinforcing rope, round wires are sequentially produced, the wires are twisted together with a rotary rotor in a spiral rope, so that two concentric layers of wires are located around the central wire, each wound wire of the outer layer located in the groove between two adjacent grafting wires of the inner layer and its surface is outside the surface of the nearest grafting wire outside He layer at a distance of not less than half the size of its own radial section. Then, the plastic compression of the rope is carried out by deformation along the outer surface of the grafting wires in at least one roller gauge, while the roller gauge is rotated relative to the axis of the rope synchronously with the rotation of the rotor of the rope machine. Next, the crimped rope is subjected to thermomechanical processing. In this case, the thermomechanical treatment of the rope may include tension of the rope and at least one heating-cooling cycle.

Due to this manufacturing method, a plastic compression of the rope is provided along the length, since each grafting wire of the rope interacting with the rollers of caliber or successive calibers is constantly crimped by the same rollers rotating together with it relative to the axis of the rope and thereby maintaining an unchanged angular and radial position relative to deformable wire, which provides on the rollers side a constant in magnitude and direction of application load on each wire Oka. Thus on the outer surface of the rope is formed continuous along the length of the graft wire pressed part. Accordingly, the wires directly interacting with the rollers act on other wires also with a constant in magnitude and direction force, forming continuous and constant in magnitude spiral faces on their own surface and the surface of the interacting wires, including the central one. Moreover, the compression continuity ensures uniformity of properties along the length of each wire, as well as the absence of pronounced stress concentrators.

In addition, a method of manufacturing a reinforcing rope at the stage of plastic crimping in a roller gauge may include the formation of a periodic profile, which is separate sections of the compressed part of the outer surface of the rope. This variant of the method of manufacturing the rope allows you to provide the highest possible characteristics of its adhesion to concrete.

In this case, plastic compression can be carried out directly in the center of the lay. This makes it possible to completely exclude the possibility of forming a defect in the so-called “flashlight” known in cable production. Also, plastic crimping can be carried out after lay. This version of the method of manufacturing the rope simplifies the implementation of plastic crimping, but requires measures to prevent the defect of the "flashlight".

In addition, after plastic crimping of the reinforcing rope, they can carry out blasting of its outer surface with bulk material. Blasting can be carried out after heating the rope and combine with its cooling in the stabilization process. Also, blasting can be carried out after heating the rope and before cooling it, after heating and cooling the rope, or before heating the rope. As bulk material can be used fraction or shavings from a material that forms an anticorrosive coating on the surface of the wires. Additional surface plastic deformation in the process of blasting with bulk material, reducing and equalizing residual stresses, increases the endurance of the rope, and simultaneously contributes to surface hardening, which is also a positive effect. At the same time, due to the increase in surface roughness, the adhesion of the reinforcing rope to concrete is further increased.

They can also form an anticorrosive coating, applying it to the surface of the wire after its manufacture and before twisting. This variant of the method allows to ensure the presence of an anti-corrosion coating on the entire surface of the wires. Moreover, in any of the above variants of the method of manufacturing a reinforcing rope with an anti-corrosion coating, zinc can be the main component of the material of the anti-corrosion coating.

The described structural embodiment of the reinforcing rope allows for high endurance due to uniform and low residual stresses in the outer surface, including in profiled sections.

A reinforcing rope is made as follows.

Pre-made wire 1, 2 and 4 of circular cross section. After manufacturing, the wires can be coated with an anticorrosion coating, for example, based on zinc. Next, the wires are twisted together into a rope using any known rope machine, for example, a yoke type. Directly in the center of the rope lay, it is crimped in a roller caliber rotating together with the rotor of the rope machine. As a result of the crimping, the wires are tightly pressed against each other and deformed, while spiral faces 5 are formed on the contacting surfaces of the central wire 1, as well as the grading wires 2 and 4 of the inner and outer layers, and on the surface of the rope in the places where the grading wires interact 2 and 4 s continuous compressed parts 6 are formed by caliber rollers. At the same time as the rope is crimped onto the outer section of the midi wires 2 of the inner layer, or the midi wires 2 and 4 of the inner and outer layers can be applied iodic profile in the form of fragments 8 of the compressed part 6, having shapes forming different from those forming 7 of the remaining surface of the compressed part 6 on which they are made.

Next, the formed rope is pulled to a force of 50-80% of the breaking force by any known method, for example, between two capstans, each of which is a set of drive and non-drive pulleys. In the interval between the passage of the first and second capstans, when the reinforcing rope is under tension, it is heated to a temperature of 370-430 degrees by means of an inductor, after which forced tension of the tensioned rope is also carried out between the first and second capstans.

In addition, after twisting the rope, its surface can be additionally blasted with bulk material in order to simultaneously increase the surface roughness and smooth out residual stresses. As bulk material can use metal shot or shavings. In addition, zinc fractions can be used as bulk material in order to simultaneously apply an anti-corrosion coating. The blasting of bulk material is carried out after twisting the rope, while the treatment of the heated rope is preferable, allowing it to affect the microstructure of its outer surface in a state where the mobility of the dislocation is maximum. Also, this treatment can be performed after cooling the rope in order to combine the effect on the microstructure of its outer surface with the mechanical removal of moisture remaining in it.

Upon completion of cooling, the rope passes through the second capstan and enters the storage coil. After the rope machine has run out of wire on at least one of the coils installed in its rotor or on the external unwinding of the coils, the technological process is interrupted for filling the rope machine with wire, at the same time, the storage coil is replaced with a similar empty storage coil, and the filled storage coil shifted to the rewind section, where the finished rope wound on a storage coil is rewound onto tare reels or coils and packaged by known methods.
