Problems solved by technology

[0003] However, due to the continuous occurrence of earthquakes and the occurrence of disasters, many bridge projects around the world have been damaged in earthquakes in recent decades, which seriously blocked the traffic lifeline in the earthquake area and further aggravated the secondary disasters caused by earthquakes. and post-disaster reconstruction efforts have brought great difficulties
At the same time, as an important social infrastructure, bridges require large investment, strong publicity, and difficult maintenance and management. Once the bridge is damaged, it will cause heavy economic losses.

Embodiment Construction

[0029] Below the present invention is further described:

[0030] see Figure 1-6 ,

[0031] The invention discloses a friction and gravity energy consumption type bridge anti-seismic block, which comprises a steel base plate 1, a steel cover 2, a grooved steel block 3, a first small steel block 4, a second small steel block 5, a steel block Block 6, steel ball 7, outer horizontal spring 8, middle horizontal spring 9, inner horizontal spring 10, vertical spring 11, heavy pulley 14, steel corbel assembly, steel baffle assembly; this embodiment is divided into two parts : core device and auxiliary device, the auxiliary device includes a steel corbel assembly and a steel baffle assembly; the core device is the device part except the auxiliary device, and the core device is a symmetrical device on the left and right sides.

[0032] Such as Figure 1-4 As shown, when the device is naturally placed, the steel ball 7 is located at the midpoint of the core device in the horizontal ...

Abstract

The invention relates to the technical field of bridge earthquake prevention, in particular to a friction and gravity energy dissipation type bridge anti-seismic check block and a construction methodthereof. The friction and gravity energy dissipation type bridge anti-seismic check block comprises a steel bottom plate, a steel cover, a groove steel block, a small steel checkblock, a steel check block, a steel ball, a transverse spring, a vertical spring, a thick and heavy pulley, a steel corbel web plate, a steel corbel bottom plate, a steel corbel top plate, a steel corbel side plate, a steel corbel bolt, a steel baffle web plate, a steel baffle top plate, a steel baffle side plate and a steel baffle bolt. In the case of earthquake occurrence, earthquake energy is converted into pulley gravitational potential energy to achieve the effect of reducing the earthquake energy on a bridge; internal components generate friction force and consume earthquake energy during movement; meanwhile,earthquake energy can be buffered through the arrangement of the steel springs, so that the problem that the bridge body moves can be relieved, even the possibility of collision between the bridge bodies is reduced, the bridge can be well protected, and harm to the bridge when an earthquake occurs is reduced.

Description

technical field [0001] The invention relates to the field of bridge anti-seismic technology, in particular to a friction and gravity energy-consuming bridge anti-seismic block and a construction method thereof. Background technique [0002] With the continuous acceleration of the urban modernization process, the large concentration of urban population, and the increasing importance of the transportation network in the lifeline of the entire city, the people's dependence on bridges is also increasing. [0003] However, due to the continuous occurrence of earthquakes and the occurrence of disasters, many bridge projects around the world have been damaged in earthquakes in recent decades, which seriously blocked the traffic lifeline in the earthquake area and further aggravated the secondary disasters caused by earthquakes. and post-disaster reconstruction efforts have brought great difficulties. At the same time, as an important social infrastructure, bridges require large in...
