Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0020] The bearing capacity of the support is 15000KN, and the rotation angle is ±0.02 radians.

[0021] The upper support plate is 1.45 meters long and 1.45 meters wide, and its lower surface is 25 centimeters away from the four sides. Side stoppers are respectively cast. The block along the bridge is 1.45 meters long, 5 cm wide, and 5 cm high; the block on the side of the bridge is 1.45 meters long, 5 cm wide, and 2 cm high.

[0022] Place a 2 mm thick stainless steel plate on the lower surface of the upper support plate, 80 cm long and 80 cm wide; place a 7 mm thick polytetrafluoroethylene plate under the stainless steel plate, 66 cm long along the bridge, and 66 cm long along the bridge 80 cm long.

[0023] A cylindrical pendulum with a radius of 1334 mm and a center height of 55 mm is placed under the Teflon plate. ...

Abstract

A steel curve face rubber shock reduction and insulation support belongs to the technical field of bridge engineering. The support comprises an upper support plate, a cylinder (ball) pendulum, a lower support plate, rubber and an inner steel plate. The cylinder (ball) pendulum is arranged between the upper support plate and the lower support plate. The cylinder pendulum is a part of a cylinder, the lower arc face of the cylinder pendulum clings to a support lower steel plate in the bridge direction. The ball pendulum is a segment, and the lower arc face of the ball pendulum clings to the support lower steel plate. A plate rubber support is arranged under the lower support plate and comprises the rubber and the inner steel plate. The support is low in construction cost and convenient to assemble and maintain.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and relates to a steel curved surface rubber shock-absorbing and isolation support, in particular to a rubber shock-isolation support with a steel cylinder surface or a steel spherical surface. Background technique [0002] The bridge support is set between the superstructure of the bridge and the piers, and its function is to transfer various load reactions on the bridge span structure to the piers, while ensuring the required displacement and rotation of the bridge span structure. Bearings are divided into ordinary bearings and seismic bearings. The anti-seismic bearing is designed according to anti-seismic requirements and can resist earthquake force. At present, the main types of shock-absorbing and isolation bearings and anti-seismic bearings in China include anti-seismic spherical steel bearings, lead-core rubber bearings and high-damping rubber bearings. The anti-seismic spher...
