The 2022 Beijing Winter Olympics has kicked off on February 4th.

International Olympic Committee President Thomas Bach said: "The Olympic Games will become the light at the end of the dark tunnel in the post-epidemic era, inspiring us and inspiring us

bright venues,

Start at the source

Composed of 3,360 pieces of curved glass, the national speed skating hall with a smart and elegant appearance covers an area of ​​about 80,000 square meters and can accommodate about 12,000 spectators

The most shocking thing about "Ice Ribbon" is its incredible steel structure

For such a large-scale steel structure building, the selection and testing of the steel is very important.

The evaluation of steel grain size is the key to the evaluation of steel industry standards

In the past, assessing grain size was simply a matter of visually determining which standard spectrum was more similar to the grain size of the material being tested, thereby determining the grain size of the material being tested

OLYMPUS Stream image analysis software allows inspectors (even if they are using microscopes for the first time) to measure industry-standard "grain size" by selecting an industry-standard and following the software-guided operating procedures, and attaching the measurement results as an additional Information is embedded in the image
.
OLYMPUS Stream image analysis software provides users with a powerful "grain discrimination" function, which enables the microscope to detect grain boundaries that are difficult to determine by ordinary software, just like the human eye

steel structure sports venues,

detection is critical

Modern large stadiums usually use advanced steel structure technology for engineering construction, and most of the tens of thousands of steel components are assembled by welding, and the quality of the welding seam directly determines the overall structural strength of the stadium
.

 

Buildings such as stadiums have high storeys and multiple suspension structures, which may bring many difficulties to detection
.
At this time, very high requirements are placed on the portability of the detection equipment

At this point, the portable and compact Olympus EPOCH 6 LT portable flaw detector, as well as the various functions of its powerful ultrasonic flaw detector, can be perfectly qualified for such inspection tasks
.
At the same time, a cord accessory kit is available to tie the instrument to the leg, or tether the instrument to a cord, freeing up the inspector's hands for better balance or probe adjustment

At the same time, inspectors can also rotate the display screen to change the view from vertical to horizontal to better observe A-scans and readings

Use vertical display mode

high-quality innovation,

fill the technical gap

On the oval "ice ribbon" is a hyperbolic saddle-shaped roof structure
.
The roof is the largest single-layer two-way orthogonal saddle-shaped cable-net roof in today's global stadiums, with a long span of about 200 meters and a short span of about 130 meters
.
It fills the gap of synchronous tensioning technology of large-tonnage and large-area super-span single-layer orthogonal cable net in China

And it is precisely because of this that "Ice Ribbon" won the "China Steel Structure Gold Award Annual Outstanding Project" award, the highest engineering award in the steel structure industry established by the China Construction Metal Structure Association, entrusted by the Ministry of Housing and Urban-Rural Development of the People's Republic of China
.

 

We believe that such high-quality stadiums are becoming a business card in China's sports industry
.
And we believe that excellent testing equipment and testing practitioners are also an important help for these "business cards" to fly all over the world
