The invention discloses a construction method for improving the horizontal precision of rail top of a crane beam steel rail. The construction method adopts a mode of matching adjusting nuts with baseplates, and the horizontal precision of the rail top is adjusted through the adjusting nuts outside the bottom of the steel rail after the steel rail is placed. According to the construction method, plates, bolts and the nuts are mainly adopted as raw materials, required parts can be obtained through simple machining, the whole process is simple in technology, materials are convenient to obtain, and the material cost is low; and the levelness of the rail top of the reinforced concrete crane beam steel rail can be controlled within +/-2 mm, the mounting precision is improved, reworking is avoided, the construction cost can be saved, and the construction cost can be controlled within a controllable range.
本发明公开了一种提高吊车梁钢轨轨顶水平精度的施工方法,采用调节螺母和垫板配合使用的方式,在钢轨放置完成后通过钢轨底部外的调节螺母来调整轨顶水平精度。本发明主要采用板材、螺栓、螺母为原材料,通过简单加工即可得到所需的零件,整个过程工艺简单,取材方便,材料成本低廉;本发明能把钢筋混凝土吊车梁钢轨轨顶水平度控制在±2mm以内,提高安装精度,避免了返工,可节约施工成本,能把施工成本控制在可控范围以内。
