建材项板是混凝土结构工程施工的重要工具。在现浇混凝土结构工程中,顶板工程一般占混凝土结构工程造价的20%~30%,占工程用工量的30%~40%,占工期的50%左右。顶板技术直接影响工程建设的质量、造价和效益,因此开展低成本、施工高效、耐用的建筑顶板研究开发,对推动我国建筑技术进步有积极意义。 Building materials board is an important tool for construction of concrete structures. In the cast-in-place concrete structure project, the roof project generally accounts for 20% ~ 30% of the cost of the concrete structure project, accounting for 30% ~ 40% of the engineering employment, accounting for about 50% of the construction period. The roof technology has a direct impact on the quality, cost and benefit of the project construction. Therefore, research and development of building roof with low cost, high construction efficiency and durability has positive significance for promoting the progress of construction technology in our country.
