本文通过分析刚性防水屋面开裂的主要原因,提出把钢纤维混凝土用于屋面刚性防水,以减少屋面裂缝,提高混凝土极限抗拉强度,并具体介绍了这种防水屋面保证防水层承重结构的刚度、在找平层上做隔离层、设分仓缝等设计要点,以及预制屋面板安装应排列整齐、屋面板或找平层应抹光、减小水灰比等施工要点。本文最后还探讨了钢纤维后撒施工法。

[摘要] 2007年6月29日,历经四审的《中华人民共和国劳动合同法》颁布,并自2008年1月1日起实施。与现行《劳动法》相比,《劳动合同法》对劳动合同签订、劳动合同解除与终止、企业规章制度、违约金等内容做出了新的规范。而违约金作为处理违约责任的一种主要形式,一直是劳动合同实践中最敏感、最复杂、最有争议的话题之一。本文将从违约金新规定的分析入手,探索企业的应对之策。  [关键词] 劳动合同法 策略
