Description
Technical field
This utility model relates to a kind of construction of road and bridge, particularly relates to a kind of precast splice type bridge pier using marmem reinforcing bar to have self-resetting capability.
Background technology
The main target of current seismic design is no collapsing with strong earthquake, repairs after not accounting for seismic Damage degree and shake.Along with design based on performance thought is rooted in the hearts of the people, people gradually recognize and limit the importance of residual displacement after shake.In such as the big earthquakes in Osaka and Kobe,Japan, more than more than 100 bridge pier residual offset rates more than 1.75%, although these bridge piers do not collapse, but lose because residual displacement is excessive and use function to have to remove.
It is strong that the reinforced concrete bridge pier using tradition reinforcing bar has energy dissipation capacity, but the feature that self-resetting capability is weak.Marmem has two character the most peculiar: shape memory effect and super-elasticity, therefore, marmem reinforcing bar can bear larger structure deformation, can return to initial elasticity position after unloading.Therefore the regular reinforcement using marmem reinforcing bar to replace areas of plasticity hinge becomes a kind of way with development potentiality.In view of marmem cost intensive, so only the areas of plasticity hinge in structure uses.There is moderate finite deformation in areas of plasticity hinge in earthquake, can automatically recover plastic deformation, thus component bulk deformation is little after earthquake, and the repair amount after shake is the least.
The mode that mechanical sleeves connects is used between marmem reinforcing bar and the adjacent regular reinforcement of plastic hinge region.The reinforced bar sleeve used in earthquake territory must is fulfilled for the standard of I level joint.It is mechanically connected sleeve and there is connection reliably, the advantages such as cost is relatively low, easy construction.
Precast assembly bridge pier is the inexorable trend of bridge industrialization development.Reinforcing bar between precast pier and cast-in-place cushion cap is by mechanical sleeves and marmem bar connecting.Bridge industrialization can be met, it is provided that self-resetting capability, the requirement of rapid construction simultaneously.
Summary of the invention
Because the drawbacks described above that prior art exists, this utility model provides a kind of precast splice type bridge pier using marmem reinforcing bar to have self-resetting capability
For achieving the above object, the technical solution adopted in the utility model is: a kind of precast splice type bridge pier using marmem reinforcing bar to have self-resetting capability, including cushion cap, prefabricated pier shaft, described cushion cap has cushion cap embedded bar, and cushion cap embedded bar stretches out cushion cap upper end certain distance, there is in described prefabricated pier shaft pre-buried vertical muscle, and pre-buried vertical muscle stretches out prefabricated pier shaft lower end certain distance, prefabricated pier shaft bottom is prefabricated with a strut, time assembled, the described cushion cap embedded bar stretching out cushion cap passes through together with mechanical sleeves and SMA bar connecting with the described pre-buried vertical muscle stretching out prefabricated pier shaft, its junction pours high-intensity fiber concrete.
Described cushion cap embedded bar and pre-buried vertical muscle are mechanical whorl reinforcing bar.Described mechanical sleeves is the reinforced bar sleeve of the I level joint standard that earthquake region uses contentedly.Described SMA reinforcing bar is made by the marmem with shape memory effect and super-elasticity feature.
Described mechanical sleeves includes inner sleeve, outer sleeve, step screwed hole it is provided with in inner sleeve, step connecting hole it is provided with in outer sleeve, step screwed hole in inner sleeve is connected with the step external screw thread male thread on pre-buried vertical muscle or cushion cap embedded bar, and the step connecting hole in outer sleeve is connected with the Step Shaft of SMA reinforcing bar.
The beneficial effects of the utility model are:
Employing marmem reinforcing bar of the present utility model has the precast splice type bridge pier of self-resetting capability by using SMA bar connecting between cushion cap and pier shaft, substantially increase the anti-seismic performance of bridge pier, and the self-resetting capability after earthquake, therefore this utility model is particularly suited for high intensity Zone, and this utility model energy rapid construction, post-disaster reconstruction is also significant.

Detailed description of the invention
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further.
As depicted in figs. 1 and 2, originally it is embodied as example and proposes a kind of precast splice type bridge pier using marmem reinforcing bar to have self-resetting capability, including cushion cap 8, cushion cap embedded bar 5, and cushion cap embedded bar 5 stretches out the outer certain distance of cushion cap 8, prefabricated pier shaft 7, pre-buried vertical muscle 6, and pre-buried vertical muscle 6 stretches out prefabricated pier shaft 7 certain distance, the prefabricated strut 3 in prefabricated pier shaft 7 bottom.
Time assembled, the cushion cap embedded bar 5 stretching out cushion cap 8 uses mechanical sleeves 1 to be connected with SMA reinforcing bar 2, and meanwhile, SMA reinforcing bar 2 is also adopted by mechanical sleeves 1 and is firmly connected with the pre-buried vertical muscle 6 stretching out pier shaft and stretching out.High-intensity fiber concrete 4 is finally used to pour.
Such as Fig. 3, shown in 4, mechanical sleeves 1 includes inner sleeve 9, outer sleeve 10, step screwed hole it is provided with in inner sleeve 9, step connecting hole it is provided with in outer sleeve 10, step screwed hole in inner sleeve 9 is threadeded with the step external screw thread axle 11 on pre-buried vertical muscle 6 or cushion cap embedded bar 5, and the step connecting hole in outer sleeve 10 is connected with the Step Shaft 12 of SMA reinforcing bar 2.Mechanical sleeves 1 is the reinforced bar sleeve of the I level joint standard that earthquake region uses contentedly.
SMA reinforcing bar 2 is made by the marmem with shape memory effect and super-elasticity feature.In view of marmem cost intensive, so only the areas of plasticity hinge in structure uses SMA reinforcing bar 2.There is moderate finite deformation in areas of plasticity hinge in earthquake, can automatically recover plastic deformation, thus component bulk deformation is little after earthquake, and the repair amount after shake is the least.
The mode that mechanical sleeves is connected is used between marmem reinforcing bar and the adjacent regular reinforcement of plastic hinge region.The reinforced bar sleeve used in earthquake territory must is fulfilled for the standard of I level joint.It is mechanically connected sleeve and there is connection reliably, the advantages such as cost is relatively low, easy construction.
