摘要
为避免地震造成的损失,设计了一种玻璃温室防震结构。该结构由工字钢框架、耗能轴承、板弹簧等组成。温室建在工字钢框架上,耗能轴承安装在框架下面,缓冲板弹簧安装在框架四周。温室移动时会受到板弹簧的缓冲作用,通过消耗能量提高温室抗震能力。温室质量15 t,缓冲墩5个,缓冲弹簧板2片,厚度8 mm,宽度50 mm,满足使用要求。耗能轴承的上板设置了浅槽,卡在槽钢上。对传统球形滚子进行了改进,设计为削面滚子,削面圆直径取5 mm。缩尺模型试验显示,相对于无缓冲装置模型,其抗震动次数提到了4倍,抗震效果明显。
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.
