Embodiment Construction

[0029] The following is further described in detail through specific implementation methods:

[0030] Such as Figure 1~6 A bridge anti-seismic anti-drop beam device shown includes a left beam body 1, a right beam body 6 and a support base 13, the support base 13 is fixedly connected to the ground through the first fixing nail 12, and the upper surface of the support base 13 is fixedly connected with a hollow column Body 27, two hollow cylinders 27 are provided with two, and two hollow cylinders 27 are respectively positioned at the upper surface both sides of support base 13, and the inner wall of hollow cylinder 27 is fixedly provided with some ring-shaped buffer protrusions 28, and hollow cylinder 27 inside The bottom is fixedly connected with an elastic buffer pad 31 , the upper side of the elastic buffer pad 31 is provided with a movable block 29 , and the outer surface of the movable block 29 is fixedly provided with an elastic rubber layer 30 .

[0031]The upper side s...

Abstract

The invention discloses an anti-seismic and anti-beam-falling device for a bridge. A first supporting column body moves up and down under the action of an elastic buffer pad, and an elastic rubber layer on the surface of a movable block rubs with an annular buffer bulge on the inner wall of a hollow column body, so that the up-down moving amplitude of the first supporting column body is reduced, and further the vibration force in the vertical direction caused by earthquake can be weakened gradually; a first spring gradually weakens vibration force in different horizontal directions, balls arearranged on the first curved surface and the second curved surface, so that the seismic force in the vertical direction is also consumed and weakened, and the anti-seismic effect is further enhanced;a second supporting column body, a supporting block, a left beam body and a right beam body are fixed together through a clamping groove and a steel cable, meanwhile, the steel cable has pulling forcein the vertical direction and the horizontal direction to fix the second supporting column body, the left beam body and the right beam body, the left beam body and the right beam body are prevented from falling off, and the anti-seismic and anti-beam-falling effects are achieved.

Description

technical field [0001] The invention relates to the technical field of bridge building construction, in particular to a bridge anti-seismic and anti-fall beam device. Background technique [0002] Earthquake is one of the frequent natural disasters. For a long time, human beings have been "powerless" in the face of this natural disaster. The direct cause of loss of life and property caused by earthquakes is the violent shaking, damage and collapse of buildings. Since the 20th century, human beings have continuously explored the structural control technology of earthquake resistance, energy dissipation and shock absorption of buildings, and successively invented and created products and technologies for structural earthquake prevention and disaster reduction. [0003] Transportation is the lifeline of the economy, and bridges are the backbone of the lifeline of the economy. When the earthquake happened, the bridge collapsed and the traffic was interrupted. The loss caused b...
