现在,许多构件生产厂在贯彻预应力混凝土构件质量检验评定标准和冷拔低碳钢丝预应力混凝土小型构件设计与施工规程方面,还存在不少问题。无论在设计上还是在施工方面,不同程度地存在各种各样的(如张拉应力不足、换筋、计算错误以及使用不合格原材料)等现象。现在将农村建房工程中小圆孔板断裂的原因分析如下。 At present, many component manufacturers still have many problems in implementing the quality inspection and evaluation standards for prestressed concrete components and the design and construction regulations for cold drawn low carbon steel wire prestressed concrete small components. Regardless of design or construction, there are various kinds of phenomena (such as insufficient tension, inflection, miscalculation, and use of unqualified raw materials). Now we will analyze the reasons for the breakage of small round hole plates in rural housing construction projects as follows.
