The vehicle is added with the layers to form multiple layers, so that the vehicle can stop in the parking lot. By the method, a five-layer real case with only two layers can be avoided, and the loss of commercial benefits of the parking lot is reduced.

2. Mode 2

When the space above the original parking lot is limited, the number of layers to be added can be determined according to the height of the real space. For example, an underground parking lot can be added by one more floor when the space height reaches 4.4 m. Namely adding one layer according to the height of 2.2 meters.

Connection method of steel structure frame

1. The stand column of the first layer of fixed dimension steel structure frame is firmly connected with the pre-buried bolt connection and steel plate welding connection on the reinforced concrete foundation.
