Junction attachment device 2, and stretch out segment concrete using stirrup encryption.
For cast-in-place cushion cap 11 when prefabricated, the vertical reinforcement that cushion cap stretches out trifle section concrete connect dress with extension upper end
The level set between 2 open pore steel plate is attached through reinforcing bar 6, and the pressure-bearing steel plate of cast-in-place cushion cap extension attachment device is pre-
8 small holes that 8 small holes stayed should be reserved with segment upper and lower side pressure-bearing steel plate are aligned.
Cast-in-place cushion cap 11 penetrates through hole in the vertical circular that center reserves interspersed prestress wire 9 when prefabricated
2 13, and a groove 12 is emptied in cushion cap bottom middle position, convenient for the tensioning and anchoring of prestress wire 9.
When precast segment assembly bridge pier is installed, the lower part pressure-bearing steel plate of upper segment is aligned with the top pressure-bearing of lower segment,
Reserved 14 position bolt 7 of small holes is attached, and the hole of the reserved interspersed prestress wire 9 of all components should be aligned,
Prestress wire 9 is finally assigned, and carries out stretch-draw anchor.
The principle of the present invention is:
In precast assembly bridge pier segment, the upper and lower side of concrete is fixedly installed attachment device at segment, to make bolt
7, which pass through 8 small holes reserved around the adjacent pressure-bearing steel plate 3 in segment stitching portion, realizes connection, improves sectional type precast assembly
Shear behavior of the bridge pier in segment junction；Attachment device mainly passes through the setting aperture steel welded on pressure-bearing steel plate 3 at segment
Level between the aperture of plate 4 and 5 connect to form entirety through reinforcing bar 6 with the vertical muscle of concrete segment；Entire precast assembly bridge pier
It can reduce precast assembly in earthquake by the self-resetting capability that longitudinal prestress wire 9 improves precast assembly bridge pier
The residual displacement of bridge pier；The anti-of the segment can be improved by stirrup encryption in the concrete segment 15 for the part that cast-in-place cushion cap stretches out
Curved performance.
The present invention realizes the connection of section assembling bridge pier by attachment device at segment and bolt, improves the prefabricated spelling of sectional type
Bridge pier is filled in the shear behavior of segment stitching portion；Prefabricated spelling is improved through all segments and cast-in-place cushion cap using prestress wire
Fill the self-resetting capability of bridge pier.It is poor in segment stitching portion shear behavior that the present invention has evaded previous sectional type precast assembly bridge pier
The shortcomings that, the reserved small holes that segment stitching portion shank of bolt passes through adjacent pressure-bearing steel plate at segment bear cutting for segment stitching portion
Power, the bending resistance that the stirrup encryption of the concrete segment of cast-in-place cushion cap extension improves precast assembly Pier are strong
Degree；The energy dissipation capacity of precast assembly bridge pier can be improved in segment junction attachment device.The present invention and previous sectional type are prefabricated
Assembled bridge pier is compared to shearing strength is big, initial stiffness is big, self-resetting capability is more preferable (residual deformation is small after shake).
