Embodiment 1

[0027] This embodiment is basically as figure 1 Shown:

[0028] The synchronous limit anti-drop beam device based on the energy consumption structure includes the first anti-fall beam structure 4 arranged on the first main beam 1 and the second main beam 2, and the first main beam 1 and the cover beam 3 , the second anti-drop beam structure 13 on the second main beam 2 and the cover beam 3 .

[0029] combine figure 2 , 3 The first anti-drop beam structure 4 includes two first embedded bases, four energy dissipation sheets 7 and stoppers. The two first embedded bases are respectively arranged on the first main beam 1 and the second main beam 2 . The interior of the first embedded seat 5 is hollow, and the side walls parallel to the first main beam 1 and the second main beam 2 are opened on the first embedded seat 5, and the first embedded seat 5 faces the first main beam 1 and the second main beam. A side wall groove is provided on the side wall of the junction of the mai...

Abstract

The invention relates to the technical field of bridges, and specifically discloses a synchronous limit anti-fall beam device based on an energy-consuming structure, including a first anti-fall beam structure and a second anti-fall beam structure; the first anti-fall beam structure includes two The first pre-embedded base, four energy-dissipating sheets and stoppers, the first pre-embedded base is fixed with a connecting seat; The connection seat is fixedly connected, and the angle between the upper and lower two adjacent energy dissipation sheets is 90°-150°; the limiter includes two limit seats, two limit plugs and a limit rod. A first sliding hole and a second sliding hole are arranged in the seat, one end of the second sliding hole communicates with the first sliding hole, the other end of the second sliding hole runs through the limit seat, and the inner diameter of the second sliding hole is smaller than that of the first sliding hole. The limit plug is slidably arranged in the first slide hole, and the two ends of the limit rod are respectively inserted into the two second slide holes and fixedly connected with the two limit plugs. The invention aims to solve the problem of energy consumption and position limitation at the same time.

Description

technical field [0001] The invention relates to the technical field of bridges, and specifically discloses a synchronous position-limiting anti-drop beam device based on an energy-consuming structure. Background technique [0002] Falling beam damage refers to the detachment, falling, and damage of the upper structure of the bridge from the lower structure, resulting in bridge damage, casualties, and property losses. Falling beam damage is one of the most common forms of bridge earthquake damage. The causes of falling beam failure are very complicated, mainly including the short lap length of the upper and lower parts of the bridge, too large expansion joints of the bridge superstructure and so on. [0003] my country's anti-fall beam research has just started, and the existing anti-fall beam devices are generally cable-type, damper energy-dissipating type or single rigid connection type. Both the cable type and the single rigid connection type are fixedly connected beam-pi...
