Embodiment 1

[0022] A bridge shock-absorbing expansion joint device that can be automatically closed, such as figure 1 As shown, including the bridge body 1, the fixed joint 2 and the damping assembly, since the bridge expansion joint is established between the two beam ends, between the beam end and the bridge abutment or between the hinged positions of the bridge, so the present embodiment The bridge body 1 is the beam end or abutment of the bridge.

[0023] The fixed connector 2 and the shock absorbing assembly are installed in combination one by one and the number of the two is two, wherein one set of fixed connector 2 and the shock absorbing assembly are located at the end of the bridge body 1 on the left, and the other group is located at the end of the right bridge body. The end of the bridge body 1; two sets of fixed connectors 2 and damping components are used to connect two bridge bodies 1 to form an expansion joint structure with automatic closing function and shock absorption f...

Embodiment 2

[0027] A bridge shock-absorbing expansion joint device that can be automatically closed, such as image 3 As shown, including the bridge body 1, the fixed connector 2 and the shock absorbing assembly, the structure and connection method of the bridge body 1 and the fixed connector 2 are the same as those in Embodiment 1. In Embodiment 2, the shock absorbing assembly not only includes the transverse connecting plate 3, the angled plate 4, the longitudinal connecting plate 5, the shock absorbing spring 6, the shock absorbing rubber 7, the shock absorbing connecting rod 8, the transverse connecting plate 3, the angled plate 4. The connection between the longitudinal connecting plate 5 , the shock absorbing spring 6 , the shock absorbing rubber 7 , the shock absorbing connecting rod 8 , and between them and the fixed connecting head 2 is the same as that in Embodiment 1. In Embodiment 2, the shock absorbing assembly further includes a top trapezoidal stress guide plate 31, a top s...

Abstract

The invention belongs to the technical field of bridge structures and specifically relates to a bridge shock absorbing expansion joint device capable of being automatically closed. The bridge shock absorbing expansion joint device capable of being automatically closed comprises bridge bodies, fixed connecting heads and shock absorbing components; the bridge bodies and the fixed connecting heads fixedly coat the end parts of the bridge bodies; the shock absorbing components comprise transverse connecting plates, bent corner plates, longitudinal connecting plates, shock absorbing springs, shockabsorbing rubbers and shock absorbing connecting rods; the fixed connecting heads fixedly coat the end parts of the bridge bodies; two groups of fixed connecting heads and the shock absorbing components are symmetrically distributed between the two adjacent bridge bodies; the two shock absorbing rubbers are attached to each other; top elastic rubbers are arranged between the two shock absorbing rubbers; and bottom corners of the two fixed connecting heads are connected with each other through bottom elastic rubber. As the bridge shock absorbing expansion joint device capable of being automatically closed contains a shock absorbing structure device capable of bearing pressure in the inclined direction, the bridge shock absorbing expansion joint device capable of being automatically closed can adapt to the pressure, generated to the bridge expansion joint in the running process of heavy objects such as vehicles, in the inclined direction.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and in particular relates to a bridge damping expansion joint device that can be automatically closed. Background technique [0002] The bridge expansion joint is an expansion joint structure designed to meet the deformation requirements of the bridge deck, which is used to allow vehicles to pass smoothly and can adapt to certain stress changes. The common bridge expansion joints are located at the ends of the two sections of the bridge body. In order to ensure the shock absorption effect between the two sections of the bridge body, most existing technologies adopt a longitudinal shock absorbing structure that can withstand longitudinal pressure or a structure that can withstand lateral extrusion. Force lateral shock absorbing structure. For example, Chinese patent CN 208266680U discloses a shock-absorbing expansion joint device for railway bridges, which adopts vertically arranged lon...
