Abstract

The invention relates to the field of the metering of intervals or gaps between spaced objects or holes, in particular to an online identification device for a bridge beam plate hinge joint state, anda use method thereof. The online identification device for the bridge beam plate hinge joint state comprises targets (3) and cameras (4) and is characterized in also comprising a wireless transmission module (5), a power supply module (6), a client side platform (7) and a cloud data side (8), wherein the targets (3) are fixed on the center of each beam plate (1), the cameras (4) are fixed on piers (2), and the wireless signal transmitting terminal of the wireless transmission module (5) and the client side platform (7) are connected with the cloud data side (8) through a wireless signal. Theuse method for the online identification device for the bridge beam plate hinge joint state is characterized in being implemented according to the following steps of installation (1), recording (2) and pushing (3). The device has the advantages of being low in cost, high in identification efficiency, simple in labeling and high in instantaneity.

Description

technical field [0001] The invention relates to the field of measuring distances or gaps between separated objects or holes, in particular to an online identification device for the state of bridge girder slab hinge joints and a method for using the same. Background technique [0002] Prestressed bridge girder-slab assembly construction is the mainstream method of bridge construction at present. In order to increase the integrity of the bridge, adjacent beams and slabs need to be hinged through steel structures. Over time, cracks can develop at the hinges, threatening the safety of the bridge. Therefore, the hinge joint must be monitored. At present, the monitoring of hinge joints mostly adopts the method of regular inspection of bridges, and the static deflection of each beam and slab is measured by measuring instruments such as total stations, so as to judge the state of each beam and slab on both sides. This method is complicated to operate and cannot realize online rea...
