JP6902925B2 - Maintenance system for bridge bearings - Google Patents

Description

The present invention relates to a maintenance system for bridge bearings.

As a member constituting a bridge, a bearing installed between an upper structure and a lower structure is known. Bearings are roughly divided into steel bearings and rubber bearings, but both are susceptible to corrosion due to installation in a narrow and inferior space, and damage such as cracking, breakage, and breakage due to the large stress acting during an earthquake.

For this reason, maintenance is carried out by regularly inspecting the bearings after they are installed and repairing them if necessary. Conventionally, when inspecting a bearing, a worker goes to the place where the bearing is installed, and at that time, he / she brings a paper book containing the design / manufacturing information of the bearing and inspects it while collating it. However, it is troublesome to search for and bring the books stored in the office, etc., which correspond to the bearings, and the management report after the inspection is also created in paper documents, so the efficiency of office work is not good.

Patent Document 1 discloses a structure deterioration detection system capable of efficiently detecting deterioration of a concrete structure by using an IC tag. However, the system described in the prior art document is limited to detecting the deterioration of the structure, and cannot confirm the information from the design stage to the maintenance management stage of the structure.

The database server 11 may be a stationary type or a cloud type installed in the company office responsible for maintenance.

The mobile terminal 12 is a mobile terminal such as a smart phone that can directly read the unique identification number registered in the IC tag 10 without going through a reader / writer as hardware, and application software for executing the mobile terminal 12 can be used. It is installed. As a terminal, a tablet can be used in addition to the smart phone.

The mobile terminal 12 also reads and displays the basic information and maintenance information of the support corresponding to the unique identification number stored in the database server 11 by communicating with the database server 11 via a line network such as an Internet line. It is possible, and it is possible to input additional maintenance information of the support corresponding to the unique identification number and send it to the database server 11, and application software for executing them is installed.

Next, the operation of the maintenance management system configured as described above will be described. The worker brings the mobile terminal 12 and goes to the installation site of the bearings 13 which are installed in large numbers. Then, when the unique identification number of the IC tag 10 attached to the bearing 13 to be inspected is read into the mobile terminal 12, the mobile terminal 12 has a main menu screen of the "bearing management system" as shown in FIG. 3, for example. Top screen) is displayed. The operation menu includes, for example, "bearing basic data", "bearing inspection manual", "inspection / repair data", "inspection route guidance", and "data transmission".
