Disclosed is a finger joint having a bridging cover plate, which enables a steel plate having a thickness much smaller than that of a conventional finger to be used and allows the vertical rotation of an upper bridge structure. The finger joint includes: a bridging cover plate installed on a first structure and supported to a second structure across a gap so as to support a load of a vehicle passing over the gap, and configured to allow relative movement between the first structure and the second structure in a direction in which the distance of the gap changes; a first finger unit connected to the bridging cover plate; and a second finger unit installed on the second structure so as to allow relative movement relative to the first finger unit in a direction in which the distance of the gap changes.

A high-damping rubber isolation bearing, an intelligent bearing and a bearing monitoring system are disclosed. The high-damping rubber isolation bearing comprises a top bearing plate, a bottom bearing plate, a high-damping rubber bearing body and a base plate, wherein at least one pressure sensing unit is arranged between the top bearing plate and the base plate, or between the bottom bearing plate and the base plate. The intelligent bearing includes a data acquisition unit, a data output unit and the high-damping rubber isolation bearing. The data acquisition unit transmits the bearing pressure measured by the at least one pressure sensing unit to the data output unit. The bearing monitoring system includes a data acquisition unit, a data output unit, a monitoring center and the high-damping rubber isolation bearing.

This application provides for flexible load bearing connectors (FLBCs) systems and methods and for monitoring, reporting, and responding to the performance and/or health of the FLBC. The system provided is an instrumented FLBC that can at least one of sense, record, report, react to and/or otherwise make use of performance and/or health information of the FLBC. The performance and/or health information can include any information related to movement (such as displacements and/or relative motions) of the FLBC and/or the system components the FLBC joins together and/or loads, vibrations, shocks, and environmental exposures the FLBC receives, transmits, supports, and/or experiences.

Disclosed are a lead core rubber seismic isolation bearing, an intelligent bearing and a bearing monitoring system, belonging to the technical field of bearings. The lead core rubber seismic isolation bearing comprises a top bearing plate, a bottom bearing plate, a lead core rubber bearing body and a base plate, wherein pressure sensing units are arranged between the top bearing plate and the base plate, or between the bottom bearing plate and the base plate. The intelligent bearing includes a data acquisition unit, a data output unit and the lead core rubber seismic isolation bearing, the data acquisition unit transmitting the bearing pressure measured by the pressure sensing unit to the data output unit. The bearing monitoring system includes a data acquisition unit, a data output unit, a monitoring center and the lead core rubber seismic isolation bearing.

Provided is a rubber bearing formed from a polychloroprene composition and having higher ozone resistance.

The rubber bearing comprises a laminate prepared by alternately laminating a plurality of soft layers having rubber elasticity and a plurality of hard layers having rigidity, and a covering layer covering an outer peripheral part of the laminate. The soft layer comprises a rubber composition containing a polychloroprene, and the covering layer comprises a blend rubber composition containing 30 to 95 parts by mass of a polychloroprene and 70 to 5 parts by mass of an elastomer other than the polychloroprene.

A partially replaceable orthotropic steel bridge deck structure is provided, including a bridge deck laid on a top of a main girder along a longitudinal direction. The bridge deck includes a heavy-vehicle lane, a medium-vehicle lane, a light-vehicle lane and an emergency lane. A top plate structure of the bridge deck includes a first top plate and a second top plate. The heavy-vehicle lane includes a first diaphragm and the first top plate. A bottom of the first top plate is connected to a longitudinal rolled U-shaped rib arranged via a blind rivet. The medium-vehicle lane, the light-vehicle lane and the emergency lane each include a second diaphragm and the second top plate. A bottom of the second top plate is welded with a longitudinal cold-formed U-shaped rib. An erection method of such orthotropic steel bridge deck structure is also provided.
