Multidirectional offset mounting method for pre-embedded bolts of prefabricated stair sliding support
The invention discloses a multidirectional offset mounting method for pre-embedded bolts of a prefabricated stair sliding support. The method includes the steps that a prefabricated stair sliding support formwork is erected; steel bars are bound in the erected formwork; each pre-embedded bolt is arranged, and the position of each pre-embedded bolt corresponds to a pin key hole of a built-in structure of a prefabricated stair; after concrete is poured, the positions of the pre-embedded bolts are adjusted after the corresponding strength is achieved; cement mortar is used for leveling layer construction at the position, corresponding to the prefabricated stair, of the sliding support; after the leveling layer reaches the strength, the prefabricated stair is hoisted and installed to a presetposition; an annular gasket is mounted in each pin key hole; an opening gasket is placed at the upper part of each annular gasket, and an opening faces the direction of the bolt; nuts are used for fastening the gaskets; and the pin key holes are filled with the cement mortar. The installation construction progress is obviously improved by adopting the multidirectional offset mounting method for the pre-embedded bolts of the prefabricated stair sliding support.
本发明公开了一种预制楼梯滑动支座预埋螺栓多方向偏位安装方法，包括以下步骤：支设预制楼梯滑动支座模板；在支设的模板内部绑扎钢筋；在设置每个预埋螺栓，位置与预制楼梯自带结构销键孔相对应；在浇筑混凝土后，达到相应强度后对预埋螺栓位置进行调整；在滑动支座与预制楼梯对应位置，使用水泥砂浆进行找平层施工；找平层达到强度后，起吊预制楼梯安装至预定位置；在每个销键孔内安装一个环形垫片；在每个环形垫片上部放置一个开口垫片，开口朝向螺栓方向；使用螺母紧固垫片；使用水泥砂浆填平销键孔，采用本方法安装施工进度明显得到提高。
