平屋面的补渗抗漏维修和隔热层的增设,已成为建筑修缮中的常见项目。维修和增设工程中,平屋面的超载,是对建筑物的主要危害。建筑施工队是工程项目施工图的实施者,对建筑设计,结构布置的可行性,一般不承担负责。在修缮项目中,情况有些不同,因建设单位的要求,建筑修缮施工队也会提供实施方案,不容忽视的是一些缺乏实践经验、对建筑结构力学基础知识、建 The repair of seepage and leak resistance of flat roofs and the addition of insulation have become common items in the renovation of buildings. In the maintenance and addition projects, the overloading of flat roofs is a major hazard to buildings. The construction team is the implementer of the construction drawings of the project. Generally, it is not responsible for the feasibility of the architectural design and structure layout. In the repair project, the situation is somewhat different. Because of the requirements of the construction unit, the construction and repair team will also provide implementation plans. It should not be overlooked that some lack of practical experience, basic knowledge of building structural mechanics, construction
