Construction And Detection Control Of Bailey Plate

The Bailey piece is welded by the upper and lower string rods, vertical rods and inclined rods. The end of the upper and lower string rods is provided with Yin and Yang joints, and the joints are provided with pestle frame connection pin holes. The string rod of Hunan Bailey piece is composed of two No. 10 channel steel (back-to-back). On the lower chord rod, there are a number of steel plates with round holes welded. In the upper and lower chord rod, there are bolt holes for connecting with the strengthening chord rod and the double truss, and in the upper chord rod, there are four bolt holes for connecting the support frame, among which the two holes are for connecting the double or multiple rows of trusses with the joint.

By describing the development and testing of Hunan Bailey tablet testing system, the test control index is determined. The process flow of testing system for Bailey tablets is put forward. Through a certain amount of testing, analysis and verification, Bailey tablets are divided into three categories: normal use, degraded use and discarded. The judgment method and criterion for quickly judging the use grade of Bailey tablets are put forward to eliminate the hidden danger in the use process and effectively ensure the safety and reliability of Hunan Berei tablets.

Due to the different service life of the truss pieces (hereinafter referred to as "the pieces"), the different working conditions (some used in offshore engineering and soaked in seawater), the maintenance process is not standard, resulting in the performance of some parts of the pieces have been reduced to varying degrees.
