我在多个工地发现,有些施工人员对砖砌体中拉结筋的具体形式、埋设位置和间距等存在模糊认识,放置也不规范。具体有以下几种状况: 1.拉结筋的制作没有按设计或规范要求下料,预埋入墙体内的长度不一; 2.120mm厚隔墙常常只留设1根直径6mm拉结筋; I found on several sites that some constructors have vague understanding of the specific form, location and spacing of the tie bars in the brickwork, and they are not normatively placed. There are several specific conditions: 1. Rigid bar production according to the design or specification requirements of the material, embedded in the wall length varies; 2.120mm thick wall often only set a diameter of 6mm pull the bar ;
