一、滚动式支座的作用 滚动式支座是压力明钢管支承结构的一种型式。它使支撑在其上的钢管,在温变时能通过放置在刚性支承环与混凝土支墩之间的圆柱形辊轮移动,并将两支承环之间的管段自重和水重安全的传到地基上。 这种支座多数用在管径比较大、温度变化产生较大位移的压力明钢管上。 二、滚动式支座的结构型式 滚动式支座是由下列一些金属构件所组成:
First, the role of rolling bearing Rolling bearing is a type of bearing structure of the pressure Ming steel. It enables the steel pipe supported thereon to move through the cylindrical roller placed between the rigid support ring and the concrete support pier during the temperature change and to pass the weight of the pipe between the two support rings and the weight of the water safely On the foundation. Most of this support used in the larger diameter, temperature changes have a greater displacement of the pressure on the steel pipe. Second, the structure of rolling bearing type rolling bearing is composed of the following metal components:
