Abstract

The invention provides a vertical force measuring type bridge support and a force measuring method. The vertical force measuring type bridge support comprises an upper support, a seat board, a bottombasin, a displacement amplification device and a displacement sensor; and the upper part of the support bears force-displacement conversion. After the support bears a vertical force, the center of a lower seat board generates a downward displacement; through the displacement amplification device, the displacement is amplified and led out of the support; through a load test, a relation between thevertical load force of the support and the reading of a displacement sensor is calibrated to realize purposes of force-displacement conversion and an easily detached and changed displacement measuringelement.

Description

technical field [0001] The invention relates to the field of bridge bearings, in particular to a vertical force-measuring bridge bearing and a force-measuring method. Background technique [0002] The bridge bearing is the main force-transmitting component directly between the upper structure and the lower structure of the bridge structure. The change of the bearing force can largely reflect the overall operation of the bridge, and realize the monitoring data collection of the bridge bearing, that is, the vertical reaction force of the bridge. , which can provide a technical basis for bridge health monitoring. With the increase of highway and railway bridge construction in our country year by year, the monitoring of the vertical static load and dynamic load of the bridge bearing has important practical significance for the operation of the bridge. [0003] At present, there are few bridge supports with vertical force measurement function. "A Spherical Multidirectional Force...
