Foundation bolt fixing device

The invention relates to a foundation bolt fixing device, and relates to the technical field of engineering construction. The embedded cylinders are in one-to-one correspondence with the foundation bolts and are in threaded connection with the foundation bolts, the upper ends of the embedded cylinders are open, and the upper surfaces of the embedded cylinders are flush with the surface of a concrete foundation. According to the device, directly-buried foundation bolts are replaced with the pre-buried cylinders, then the equipment is clamped and fixed through the foundation bolts and the pre-buried cylinders, and the situation that after a concrete foundation is solidified, the foundation bolts stretch out of the ground, and consequently carrying and placing of the equipment are hindered is reduced. 本申请涉及一种地脚螺栓固定装置，涉及工程施工技术领域。其包括多个地脚螺栓，以及多个与地脚螺栓一一对应且螺纹连接的预埋筒，所述预埋筒上端开口，且预埋筒的上表面与混凝土地基的表面平齐。本申请通过将直接埋设的地脚螺栓更换成预埋筒，再用地脚螺栓和预埋筒对设备进行夹紧固定，减少了混凝土地基凝固后，地脚螺栓伸出地面对设备的搬运和放置造成阻碍的情况。
