Shenzhen Baoan District building engineering Quality testing center: Residual deformation measurement project of steel mechanical connectors
Implementation of the People's Republic of China industry standard JGJ107-2010 (record number: J986-2010) steel mechanical connection technical regulations,However, most residual deformation measuring devices sold on the market use extensometers as measuring methods,There are some shortcomings, such as asymmetric data, low accuracy, excessive error after lengthening the marker bar of extensometer,Seriously does not comply with JGJ107-2010 technical regulations,Nor can it meet the actual needs of our customers。
For better response standards,And to meet customer needs to a large extent,After the company's technical personnel to tackle the problem,In June 2011, a new measuring device for residual deformation of steel mechanical joint was developed,The device adopts digital displacement sensor as measuring mode,The problem of data asymmetry and data inaccuracy is completely solved,At the same time reasonable specimen clamping device design,Solved the problem that the marker bar can be lengthened,Through the use of several microcomputer controlled electro-hydraulic servo universal test machines of different manufacturers in the building engineering quality testing center of Bao 'an District, Shenzhen,Fully in line with the People's Republic of China industry standard JGJ107-2010 (record number: J986-2010) steel mechanical connection technical specifications。
The residual deformation measuring device of steel mechanical joint has been successfully applied for patent, and has been successfully used in many units such as Futian District Building engineering Quality Testing Center of Shenzhen City and Longgang District Building Engineering Quality Testing Center of Shenzhen City。
