Pier top displacement spring limiter for high-pier bridge
The invention discloses a pier top displacement spring limiter for a high-pier bridge. Stiffening steel plates are respectively arranged on a stand column or the lateral side of a cover beam and the bottom of a main beam; the stiffening steel plates are connected with the stand column or the cover beam, and the main beam through bolts; a plurality of springs are arranged between vertical stiffening steel plates anchored on the stand column or the lateral side of the cover beam; the other ends of the springs are fixed on the same steel plate, and a certain clearance is reserved between the steel plate and a steel plate anchored on the main beam to play a limiting role when the longitudinal displacement of the pier top is too large; the connection between the stiffening steel plate and the cover beam as well as between the stiffening steel plate and the beam bottom is designed according to anchoring requirements. When the displacement of the pier top is too large, soft collision can enable the springs to deform and consume energy so as to reduce and limit the displacement, the accumulated effects can be reduced and limited, and the phenomenon that because the accumulated displacement of the pier top is too large, the stress of the pier is adverse can be avoided; besides, the performance of the pier top displacement spring limiter can be adjusted through the adjustment of the width of the clearance and the category of the springs.
