Recently, the construction of the first 3D printed bridge railing in Nanjing was completed.
After the design of the bridge railing is completed by the designer, the three-dimensional building model is simulated by computer, and then the data is transmitted to the large-scale construction-dedicated 3D printer for manufacturing.
Bridge manufacturers say that it takes more than a month to build a bridge using conventional processes, and with 3D printing technology , it takes only 15 days from design to manufacturing, saving a lot of time. Moreover, the advantage of using 3D printing manufacturing is that in addition to cement and quartz sand, the main material is also added with environmentally friendly additives, which is stronger than traditional building materials, and has no dust problem and is more environmentally friendly.
It is understood that this bridge construction project, as part of the Nanjing Dangerous Bridge Reconstruction Plan, used 3D printing technology for the first time.
Swing Turnstile Gate characteristics
1. Practicability: The swing barrier gate adopts non-contact IC or ID card, which successfully solves the problems of one card with multiple functions, confidentiality, no wear, and easy operation, which greatly improves the practical application.
2. Convenient expansion: The computer and the mechanical swing turnstile gate use 485 bus communication, so the expansion is convenient.
3. It can be used offline: the full automatic swing barrier gate can not only be used in conjunction with a computer network, but also can be used offline.
4. Reset function: After the personnel pass through the channel, the swing baffle gate will reset by delay or infrared induction.
5. Convenient counting: The RFID swing turnstile gate can be displayed on an external screen to facilitate the management of the flow of people.
