混凝土叠合箱网梁楼盖在某地下车库中的应用

混凝土叠合箱网梁楼盖是一种新型的楼盖形式,是由小型预制构件(混凝土叠合箱)与现浇混凝土肋梁结合成具有连续箱型截面的整体结构,箱体与肋梁共同受力.与传统的楼盖形式相比,它具有预制构件工厂化加工、施工质量稳定、减少施工现场劳动强度、降低环境污染等优点,也具有现浇结构整体性好的特点.但该工艺在国内工程实例中应用还相对较少,施工标准也不是很完善.结合某车库工程,详细介绍了这一新型的楼盖施工方法及施工中应注意的问题,对今后类似工程的施工具有重要的实践指导意义.

The Application of Concrete Composite Box Net Joint Floor in Underground Garage Engineering

The concrete composite box net joint floor is one kind of new-style floor.It is composed of the small prefabricated component with the cast-in-place concrete rib beam.The box and rib beam form a whole structure that has continuous box section and undertake the load together.Compared with the traditional concrete floor,the new style has some traits,such as component factory-prefabrication,steady construction quality,reducing workload and environment pollutions,etc.Also,it has the integrity of cast-in-place concrete floor structure.However,this floor technique was used less in the domestic engineering,and the related construction criteria were not very perfect.So,taking the engineering as an example,the construction method and some problems deserving attention about this new floor style are presented in details,which is of great significance for similar projects in the future.
