澡塘梁板裂缝产生的原因及加固处理方法

高湿环境下混凝土保护层过薄是导致钢筋锈蚀膨胀而引起梁板裂缝的主要原因之一 ;同时 ,梁板刚度较小、梁板裂缝控制宽度较大以及施工质量低劣 ,都加快了钢筋锈蚀 .实际表明 ,采用梁下增加支座和板下做“板下整体式补强”对澡塘梁板进行加固 ,方法简单实用且行之有效 .

The causes of the beams and slab cracks of the bathrooms and the reinforcement methods

In high humity surroudings, the thickness of protection for concrete, which are thinner will make reinforcement rusty, expanded and cause beams and slab crack. Meanwhile, the stiffiness of beams and slab are smaller, the width of control crack are bigger. The poor quality for construction will make rust faster. The construction performances have showed that to add stanchion under beams and whole replenishment under slab is simple and efficient.
