Big noise, vibration does not say, protruding corners will soon have a lot of crushed cars, parking Which benefits, reduced non-slip effect. Such an approach should not be used in the design. The correct approach as shown in Figure 2, on the street parking garage, make lateral grooves. Pitch of the grooves should not be too dense. In practice the groove pitch 100 ~ 170mm, parking garage Which is good, depth 60 ~ 70mm is appropriate. Similar houses!

The study effect to fill the gap, reached the international advanced level. Live in total Group, a joint China Academy of Building Research Institute building fire, City Fire Department, Tsinghua University public safety research center, China University of Science and State Key Laboratory of Fire Science, technology, the project is the Municipal Science and Technology Commission. More than two years to complete. Fire problems exist with the existing parking garage, the project research group analyzed the current situation at home and abroad to stop the underground automated mechanical parking system performance based fire safety design.
