Abstract: In order to avoid the phenomena, a mechanical device was designed, which was made up of double T-steel frame, plane bearing and buffer spring. The greenhouse was built on I-steel frame. Plane bearings were mounted under the frame. The buffer plate spring was installed around the frame. When the greenhouse moved, it will be buffered by plate springs. Seismic capacity of the greenhouse will be improved by consuming energy. Greenhouse quality was 15 t, buffer plate spring was 5, spring plate takes was 2. The thickness was 8 mm, and the width was 50 mm, the produced stress will meet the requirement. Shallow groove was designed for the upper plate of plane bearing, which sandwiched on I-steel. Spherical roller was improved designed. The ball was flattened up and down. Two sides were parallel. The diameter of cut face was 5 mm. The vibration test showed that the buffer device has a fold increase in anti collapse capability compared with the non buffer device. Seismic effect was obvious.
