Abstract
The utility model relates to a built-in driver for a shape memory alloy, belonging to the technical field of the shock absorption of civil engineering structures and solving the problem that a traditional reinforced concrete structure is low in safety. The built-in driver comprises stranded wires and leads, wherein the stranded wires include seven martensite phase transformation SMA (Shape Memory Alloy) monofilaments which are twisted together in a stranded wire manner; multiple stranded wires are longitudinally and transversely arrayed to form a net shape, the separation distances of the stranded wires arranged in a net shape manner are equal, the intersection points of the stranded wires arranged in the net shape manner are fixedly connected, and both two ends of multiple stranded wires are respectively and fixedly connected with one lead; the leads are copper wire cables with sheaths. In a use process, the built-in driver for the shape memory alloy is distributed in the reinforced concrete structure and is electrified and heated through the leads according to requirements, so that the rigidity and the damping of the reinforced concrete structure are changed, and the safety of the reinforced concrete structure is improved. The built-in driver for the shape memory alloy is applied to the reinforced concrete structure.
Description
Technical field
The utility model belongs to civil engineering structure cushion technique field, is specifically related to the marmem built-in drive of using in a kind of concrete structure.
Background technology
Traditional reinforced concrete structure safety is not strong, the self-regulation ability that itself possesses stiffness and damping is minimum, for resisting the natural calamities such as earthquake, high wind, Seismic Design of Reinforced Concrete Structure and Wind-resistant design method are the sectional dimensions that improves the strength grade of material and strengthen member, can not fundamentally change the safety of steel concrete itself.
Marmem Shape Memory Alloy is abbreviated as SMA, martensite phase transformation SMA has can realize the various deformation form, easily be combined with matrix, high damping, modulus of elasticity can change along with the variation of temperature, can produce the characteristics such as restoring force during limited reply, if these characteristics that can utilize martensite phase transformation SMA change it characteristics such as the stiffness, damping of reinforced concrete structure as inner drive, thereby the ability that makes reinforced concrete structure resist the natural calamities such as earthquake, high wind is strengthened, the safety that can improve steel concrete.
The utility model content
Order of the present utility model ground is in order to solve traditional not high problem of reinforced concrete structure safety, a kind of marmem built-in drive to be provided, and concrete scheme is as follows:
The marmem built-in drive, it comprises twisted wire and wire, and described twisted wire comprises seven martensite phase transformation SMA monofilament, and described seven martensite phase transformation SMA filament diameters are identical, and described seven martensite phase transformation SMA monofilament are twisted together with the twisted wire form; Described twisted wire has many, described many twisted wires are arranged into netted in length and breadth, and described netted many twisted wire spacings of arranging are identical, and described netted many twisted wire intersections of arranging are fixedly connected with, described many twisted wire two ends all are fixedly connected with a wire, and described wire is the copper core cable with sheath.
The beneficial effects of the utility model are: can change frequency and the damping ratio of concrete structure, improve the safety of concrete structure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross sectional representation of twisted wire in the utility model.
The specific embodiment
With reference to figure 1 and Fig. 2, the marmem built-in drive, it comprises twisted wire 1 and wire 2, and described twisted wire 1 comprises seven martensite phase transformation SMA monofilament 1-1, described seven martensite phase transformation SMA monofilament 1-1 diameters are identical, and described seven martensite phase transformation SMA monofilament 1-1 are twisted together with the twisted wire form; Described twisted wire 1 has many, described many twisted wires 1 are arranged into netted in length and breadth, described netted many twisted wires 1 spacing of arranging is identical, described netted many twisted wires 1 intersection of arranging is fixedly connected with, each is fixedly connected with described netted many twisted wires 1 two ends of arranging with an end of a wire 2, and described wire 1 is the copper core cable with sheath.
Using method is: at first this marmem built-in drive is applied prestrain, make the distortion of this marmem built-in drive surpass its elastic deformation, then this marmem built-in drive is arranged in reinforced concrete structure, can replace the main muscle of part, described wire 2 stretches out outside reinforced concrete structure, as required by the heating of switching on of 2 pairs of this marmem built-in drive of described wire, thereby change stiffness and the damping of reinforced concrete structure, increase the safety of reinforced concrete structure.
Operating principle of the present utility model is: utilize martensite phase transformation SMA to have and can realize the various deformation form, easily be combined with matrix, high damping, modulus of elasticity can change along with the variation of temperature, can produce the characteristics such as restoring force during limited reply, it is changed the characteristic such as stiffness, damping of reinforced concrete structure as inner drive, thereby the ability that makes reinforced concrete structure resist the natural calamities such as earthquake, high wind is strengthened, the safety that has improved steel concrete.Copper core cable is ductile, and intensity is high, antifatigue, and the advantage such as corrosion-resistant uses the copper core cable with sheath can increase physical life of the present utility model.
