现浇混凝土空心楼板是近几年国内发展起来的结构新技术,它适应大空间、大跨度柱网的住宅和大空间公共建筑的要求,具有自重轻、降低地震作用、减小楼板配筋量、楼板隔声效果好等优点,受到建设项目业主的欢迎。一、LPM轻质材料位于北京市大兴区的某培训楼工程主报告厅顶板(轴线尺寸为13200mm×14400mm)为现浇空心楼板,板厚450mm,采用LPM轻质材料填充楼盖技术,板内预埋填充材料为LPM材料。
Cast-in-place concrete hollow floor is a new structure developed in China in recent years. It adapts to the requirement of large space and large-span column network for residential buildings and large space public buildings. It has the advantages of light weight, reducing earthquake and reducing the amount of floor reinforcement , Floor sound effect is good, etc., by the construction project owners welcome. LPM lightweight materials The roof of the main lecture hall (axis size: 13200mm × 14400mm) of a training building located in Daxing District of Beijing is a cast-in-place hollow slab with a plate thickness of 450mm. LPM lightweight materials are used to fill the floor, The embedded filler material is LPM material.
