Light interlayer prefabricated floor slab and preparation method thereof
The invention relates to a light interlayer prefabricated floor slab and a preparation method thereof. The prefabricated floor slab comprises a slab body, shear keys, filling bodies and lower tensile steel bars. The shear keys are cross-shaped shear keys, and shear key reinforcement holes are formed in the lower parts of the shear keys; the filling body is a thin-wall filling body and is provided with a thin-wall shell, and a hollow cavity or a high-temperature heat insulation material is arranged in the thin-wall shell; the thin-wall filling bodies are distributed in the area outside the cross-shaped shear keys, gaps are reserved between the four side faces of the plate body and the thin-wall filling bodies, and floor slab bolt holes penetrating through the plate body in the thickness direction are formed in the reserved gaps. The lower tensile steel bars are arranged in the length direction of the plate body, and the multiple lower tensile steel bars are arranged in the width direction of the plate body at intervals. The preparation method comprises the steps of building the supporting formwork, placing the shear keys, laying the lower tensile steel bars, connecting the supporting rods, pouring for the first time, placing the filling body, pouring for the second time and removing the formwork. The light interlayer prefabricated floor slab has excellent mechanical property and heat preservation, heat insulation and sound insulation performance and is convenient to construct.
本发明涉及一种轻型夹层预制楼板及其制备方法，预制楼板包括板体、剪力键、填充体和下部受拉钢筋；剪力键为十字形剪力键，下部设有剪力键钢筋孔；填充体为薄壁填充体，具有薄壁外壳，薄壁外壳内为中空腔或高温隔热材料；薄壁填充体分布在十字形剪力键以外的区域，且板体的四个侧面与薄壁填充体之间留有间距，在所留间距处设有贯穿板体厚度的楼板螺栓孔；下部受拉钢筋沿板体长度方向设置，且多根下部受拉钢筋沿板体宽度方向间隔排布；所述制备方法包括搭建支护模板、放置剪力键、铺设下部受拉钢筋、连接支撑杆、第一次浇筑、放置填充体和第二次浇筑并拆除模板。该轻型夹层预制楼板具有优良的力学性能和保温隔热隔声性能，且便于施工。
