Description
Technical field
The utility model belongs to architectural and civil engineering field, more particularly to a kind of SMA for reinforced concrete structure
Muscle plasticity hinge connector.
Background technology
Reinforced concrete structure is the most widely used a kind of structure type in field of civil engineering, plays and extremely weighs
The effect wanted.Although reinforcing bar has good intensity, rigidity, ductility and an applicability, however its can be produced after geological process compared with
Big residual deformation, and the constantly accumulating residual deformation under the effect of consecutive shock disaster, cause structural seismic performance gradually to move back
Change, or even collapse, so that the feature after structure shake can not be ensured, it is necessary to very big maintenance and rehabilitation cost.Therefore, carry
The ability of high reinforced concrete structure resistance consecutive shock disaster effect turns into urgent problem to be solved.
Utility model content
The technical problems to be solved in the utility model is that the drawbacks described above for how overcoming prior art is used for steel there is provided one kind
The SMA muscle plasticity hinge connectors of tendon concrete structure.The SMA muscle plasticity hinge connectors for being used for reinforced concrete structure cause existing
There is reinforced concrete structure to keep good anti-seismic performance under consecutive shock effect.
In order to solve the above technical problems, a kind of SMA muscle plasticity for reinforced concrete structure of the utility model is hinged
Device, connects SMA connecting rods between two sections of reinforcing bars, is connected between reinforcing bar and SMA connecting rods by stainless steel sleeve head and the tail, stainless steel sleeve
Cylinder is connected with bar connecting one end using taper thread, and stainless steel sleeve, which is connected one end with SMA connecting rods and fixed using bolt presses, to be connected
Connect.
As optimization, the cross section of the stainless steel sleeve is cylindrical, and one end is provided with carries out taper thread machinery with reinforcing bar
The cone cylinder shape groove of connection, the other end is provided with carries out the cylinder shape groove that bolt presses are fixedly connected with SMA connecting rods, connection
Longitudinally arranged zigzag guide rail in the cylinder shape groove of the stainless steel socket end of SMA connecting rods, connects the stainless steel sleeve of SMA connecting rods
The cylindrical hole slot inwall at cylinder end is provided with the zigzag guide rail groove matched with the zigzag guide rail.
As optimization, the zigzag guide rail is evenly arranged three along longitudinal direction, be respectively arranged in cylindrical hole slot inwall by
In the zigzag guide rail groove of 120 grades point processing.
The beneficial effects of the utility model are：
The utility model, simple in construction, design science, easy construction are economic and practical, for reinforced concrete structure,
Its areas of plasticity hinge places SMA " plastic hinge " connector so that structure can occur large deformation and not destroy, while in geological process
Recover deformation after end, small residual deformation is only existed, so as to improve reinforced concrete structure under consecutive shock disaster
Anti-seismic performance.Reinforced concrete member is overcome to resist the defect of consecutive shock disaster ability；In addition, not changing the outer of concrete
Shape size, and convenient, economically feasible of constructing, are that one kind effectively improves reinforced concrete structure resistance consecutive shock disaster ability
Method.With preferable actual application value and promotional value.
Brief description of the drawings
A kind of this SMA muscle plasticity hinge connector for reinforced concrete structure is made furtherly below in conjunction with the accompanying drawings
It is bright：
Fig. 1 is a kind of structural representation of SMA muscle plasticity hinge connectors for reinforced concrete structure of the utility model；
Fig. 2 is the structural representation of I-I sections in Fig. 1；
Fig. 3 be three layer one of the utility model one embodiment across reinforced concrete frame structure schematic diagram.
In figure：1 it is reinforcing bar, 2 be stainless steel sleeve, 3 be bolt, 4 be SMA connecting rods, 5 is zigzag guide rail.
Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, develop simultaneously implementation referring to the drawings
Example, the utility model is further described.
As shown in Figure 1-2, this kind of SMA muscle plasticity hinge connector for reinforced concrete structure, two sections of reinforcing bars 1 it
Between connection SMA connecting rods 4, connected from beginning to end by stainless steel sleeve 2 between reinforcing bar 1 and SMA connecting rods 4, stainless steel sleeve 2 and reinforcing bar 1
Connect one end to connect using taper thread, stainless steel sleeve 2 is connected one end with SMA connecting rods 4 and is fixed connection using bolt 3.
It is so designed that, SMA connecting rods is introduced in reinforced concrete structure, forms the combination muscle of reinforcing bar-SMA- reinforcing bars, not only
The anti-seismic performance of structure is improved, and significantly reduces the residual deformation of structure to reduce the economic damage that earthquake is brought
Lose, good anti-seismic performance can be kept under consecutive shock effect, it is ensured that life security and property safety.Further, since
SMA connecting rods are very sensitive to indentation, and its intensity, therefore stainless steel sleeve and reinforcing bar, the connection of SMA connecting rods can be reduced using screw thread
Processing methods different Shi Caiyong, is connected with bar connecting one end using taper thread, one end is connected with SMA solid using bolt presses
Fixed connection.
Specifically, the cross section of the stainless steel sleeve 2 is cylindrical, one end is provided with carries out taper thread machinery with reinforcing bar 1
The cone cylinder shape groove of connection, the other end is provided with carries out the cylinder shape groove that bolt presses are fixedly connected with SMA connecting rods 4, connection
Longitudinally arranged zigzag guide rail 5 in the cylinder shape groove at the end of stainless steel sleeve 2 of SMA connecting rods 4, connects the stainless of SMA connecting rods 4
The cylindrical hole slot inwall at the end of steel bushing 2 is provided with the zigzag guide rail groove matched with the zigzag guide rail 5.So set
Meter, is connected firmly, easy to use.
Specifically, the zigzag guide rail 5 along longitudinal direction be evenly arranged three, be respectively arranged in cylindrical hole slot inwall by
In the zigzag guide rail groove of 120 grades point processing.It is so designed that, connects more firm, using more convenient.
Above-mentioned embodiment is only specific case of the present utility model, is not to make other forms to the utility model
Limitation, any those skilled in the art are changed or are modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But every content without departing from technical solutions of the utility model, according to technology of the present utility model
Any simple modification, equivalent variations and remodeling that essence is made to above example, should all fall into patent of the present utility model and protect
Protect scope.
