Prestressed hollow slab non-overlapping floor system of multi-story building and construction method of prestressed hollow slab non-overlapping floor system
According to the multi-story building prestressed hollow slab non-overlapping floor system and the construction method thereof, a floor system frame comprises a unit frame, prestressed hollow slabs are distributed in the unit frame and are in lap joint with the side edges of the unit frame, and slab joints of key groove structures are formed between the slab sides of the adjacent prestressed hollow slabs in the unit frame; when the side edge of the unit frame is located at the edge of the floor system frame, a sealing plate is fixedly arranged on the side edge of the unit frame, and a pouring groove is formed among the sealing plate, the prestressed hollow plate and the side edge of the unit frame; and when the side edges of the unit frames are located in the middle of the floor system frame, second pouring grooves are formed between the side edges of the unit frames and the prestressed hollow slabs on the two sides of the unit frames, studs are evenly distributed on the bottom faces of the pouring grooves and the second pouring grooves, and fine aggregate concrete is poured after reinforcing steel bars are arranged in slab joints, the pouring grooves and the second pouring grooves. A concrete laminated layer is not arranged, the floor system meets the building requirement, the building construction speed of a building is greatly increased, cost is low, and the system is particularly suitable for a multi-story building with the requirement for the short construction period.
一种多层建筑预应力空心板不叠合楼盖及其施工方法，楼盖框架包括单元框架，预应力空心板分布在单元框架内并搭接在单元框架的侧边上，单元框架内相邻的预应力空心板板侧之间设有键槽结构的板缝；当单元框架的侧边位于楼盖框架边缘时，在单元框架的侧边上固设封板，封板、预应力空心板和单元框架侧边之间形成浇筑槽；当单元框架的侧边位于楼盖框架中部时，则单元框架的侧边与其两侧的预应力空心板之间形成第二浇筑槽，在浇筑槽和第二浇筑槽的底面上均分布有栓钉，在板缝、浇筑槽和第二浇筑槽内设置加固钢筋后灌注细石混凝土。不设置混凝土叠合层并使楼盖满足建筑要求，建筑的建造速度大幅提升，且成本低，特别适用于要求建筑工期短的多层建筑。
