在混凝土或钢筋混凝土结构中埋设地脚螺栓,通常采用预留洞二次灌浆的施工方法。可是当留洞过多或密度过大时,往往会影响混凝土构件的强度和抗裂性能,还会给施工带来很大麻烦。为了克服这些弊病,基建工程兵某部六连和六○五研究所工程技术人员在“水池工程”施工中,对埋设精度很高的大量地脚螺栓试用了“直接预埋”的方法并获得了成功。
For anchor bolts embedded in concrete or reinforced concrete structures, the method of secondary grouting with reserved holes is usually used. However, when there are too many holes or the density is too large, the strength and crack resistance of the concrete member are often affected, and the construction is also greatly troubled. In order to overcome these shortcomings, the engineering and technical personnel of the 6th and 6th Research Institute of a certain infrastructure engineering force used a large number of anchor bolts with high precision to try the “direct embedding” method and obtained the “pool engineering” construction. success.
