在工业建筑中,往往存在设备的螺栓与混凝土基础的连接问题,如图1所示。由于直接将设备的地脚螺栓埋入混凝土中,地脚螺栓没有活动的余地,土建施工也很困难,满足不了设备安装的要求。因此,多年来,土建设计时多采用图2所示的作法。 In industrial buildings, there are often problems with the connection of equipment bolts to concrete foundations, as shown in Figure 1. Because the anchor bolts of the equipment are directly embedded in the concrete, there is no room for movement of the anchor bolts, and the civil construction is also difficult to meet the requirements of equipment installation. Therefore, for many years, the construction of the soil has used more of the method shown in Figure 2.
