我国1976年颁布的《钢筋混凝土预制构件质量检验评定标准》(TJ321-76)(以下简称老标准),对保证钢筋混凝土预制构件的质量,发挥了应有的作用。但随着我国科学技术的发展,已不能完全适应当前情况。为此组成了标准修订组,对老标准进行修订,并写出了讨论稿。讨论稿对老标准的正文部分作了较大的修改,并增加了新内容,使之同已经颁布施行的《钢筋混凝土工
China’s “Test and Assessment Standard for Quality of Reinforced Concrete Prefabricated Components” (TJ321-76) (hereinafter referred to as the old standard) promulgated in 1976 has played its due role in ensuring the quality of reinforced concrete precast components. However, with the development of science and technology in our country, we can no longer fully adapt to the current situation. To this end, a standard revision group was formed to revise the old standards and write a discussion paper. The discussion paper made major changes to the main part of the old standard and added new content to make it compatible with the already issued “reinforced concrete workers”.
