根据砼裂缝成因,采取适当措施进行预防要比事后补救有效的多。也就是说采取以防为主的方法,归纳起来。1.采取适当以防为主措施的以下几个方面1.1设计在设计上要注意到那些容易开裂的部位,如深基与浅基、高低跨处等,应考虑到由于地基的差异沉降或结构原因而引起的薄弱环节,在设计中加以解决。在构件截面允许、配筋率不变而且浇筑方便和条件下,钢筋直径越细、间距越小则对预
According to the causes of the cracks, it is more effective to take appropriate measures for prevention than afterwards. That is to say, the method of prevention is the main method. 1. Take appropriate precautions in order to prevent the main aspects of the following aspects 1.1 Design in the design should pay attention to those parts that are prone to cracking, such as deep and shallow base, high and low cross, etc., should take into account the difference in settlement due to foundation or structure The weak links caused by the reasons are solved in the design. The finer the diameter of the steel bar and the smaller the distance, the better the prefabrication of the member cross section, the constant reinforcement ratio, and the ease of pouring.
