Digitized testing of hollow-core elements in accordance with: NS-EN1168:2005+A3:2011<\/h2>\n

When starting up production of hollow-core elements, several tests has to be done and cleared before the elements can be utilized in construction projects. Since there were no effective setup made to complete these tests, we’ve decided to take matters into our own hands.<\/p>\n

The result was a one of a kind testing rig in Norway.<\/p>\n

Why we developed our testing rig<\/h2>\n

There are strict regulations and requirements for producing and testing hollow-core elements. If the mixing ratio or construction method of the hollow-core element is changed in any way, new tests has to be performed and approved.<\/p>\n

When Helgeland Betong wanted to optimize their products, we had to perform new tests on all our altered products. When examining the current rules and regulations about testing our products, we concluded that manually-controlled testing was not a good solution. In addition, performing tests off-site would prove to be a costly endeavour. Our solution was innovation. <\/p>\n<\/div>\n

Development<\/h2>\n

In short, current testing requirements demands exposing the hollow-core elements to different levels of loads, in a sequential manner. The load on the hollow-core element is gradually increased until it cracks. It was clear that in order to achieve detailed and comparable results, the testing process would have to be automated. <\/p>\n

Our analogue pressure plate was therfore equipped with a digital control interface. A new software was developed to handle the test, and analysing and storing the results from the tests. The testing rig is now controlled digitally, with an integrated hydraulic unit. Every setting and adjustment is easily done on a touchscreen, and all results can be sent out digitally with a standardized post-test document. <\/p>\n

Our first of its kind digital testing rig was approved by Kontrollr\u00e5det (The Norwegian construction certification council).<\/p>\n<\/div>\n
