Preparation method of ceramsite concrete prefabricated composite floor slab
The invention relates to the field of concrete prefabricated floor slabs, and particularly discloses a preparation method of a ceramsite concrete prefabricated composite floor slab. The preparation method of the ceramsite concrete prefabricated composite floor slab comprises the following steps that (1) a mold release agent is smeared in a prefabricated composite floor slab mold, and then an embedded part and a reinforcing mesh are installed; (2) manufacturing a reinforcing mesh protective layer; (3) pouring is conducted, specifically, after pouring is completed, a wood board is placed above the mold, ceramsite in concrete is vibrated to the bottom of the mold through an up-down vibrator, the vibration time is 10-20 min, and after vibration is completed, the wood board is removed; then, a pouring surface is troweled manually; and (4) after the pouring face is trowelled, an accelerator is sprayed, formwork removal is conducted after hardening, and the prefabricated composite floor slab is obtained. According to the method, the phenomenon that ceramsite in the concrete of the prefabricated composite floor floats upwards can be effectively reduced, and therefore the good quality of the prefabricated composite floor can be guaranteed.
本申请涉及混凝土预制楼板的领域，具体公开了一种陶粒混凝土预制叠合楼板的制备方法。一种陶粒混凝土预制叠合楼板的制备方法包括以下步骤：（1）在预制叠合楼板模具内涂抹脱模剂，然后安装预埋件和钢筋网片；（2）制作钢筋网片保护层；（3）浇筑，浇筑完成后，在模具上方放置木板，采用上下式振捣器将混凝土内的陶粒向模具底部振捣，振捣时间为10‑20min，振捣完成后将木板撤去；然后人工抹平浇筑面；（4）抹平浇筑面后，喷洒速凝剂，硬化后拆模，得到预制叠合楼板。本申请的方法能够有效减少预制叠合楼板是混凝土内的陶粒出现上浮的现象，从而有利于使叠合预制楼板保证良好的质量。
