Construction method of cast-in-situ concrete hollow floor system
The invention relates to a construction method of a cast-in-situ concrete hollow floor system. the method comprises the steps of manufacturing a cavity component in advance, erecting a floor bottom formwork, arranging bottom steel reinforcement bars on the bottom formwork, placing the cavity component, installing anti-floating screw nails, arranging ribbed beam steel bars and panel steel bars, andcasting concrete, wherein the cavity component comprises a pot-shaped formwork shell and a sealing plate, a vertical groove is formed in the peripheral side wall of the pot-shaped formwork shell, andpot opening bars are arranged at the pot opening. Each anti-floating screw nail comprises a head, a rod body and a rod body tail end with a threaded tip, wherein a gasket is arranged between the headand the sealing plate, the rod body penetrates through the sealing plate of the cavity component and the vertical groove in the peripheral side wall, and the tail end of the rod body with the threaded tip is screwed into the floor bottom formwork through the tool so that the cavity component can be tensioned and fixed. The method can be widely applied to the field of cast-in-situ concrete hollowfloor systems, and has the advantages of being low in construction cost and high in speed, and the problem that floating and drifting appear in the concrete casting process is solved.
本发明涉及一种现浇砼空心楼盖的施工方法，步骤包括预先制作空腔构件，支楼板底模板，在底模板上布设底部钢筋，放置空腔构件，安装抗浮螺杆钉，布设肋梁钢筋和面板钢筋，浇捣砼等。其中，空腔构件包括盆状模壳和封口板，盆状模壳的四周侧壁设置有竖向凹槽，且盆口设置有盆口筋；抗浮螺杆钉包括头部、杆身和带螺纹尖头的杆身末端，其头部与封口板之间设置有垫片，杆身穿过空腔构件的封口板及四周侧壁的竖向凹槽，通过工具使带螺纹尖头的杆身末端旋入楼板底模板上将空腔构件拉紧固定。本发明可广泛应用于现浇空心楼盖领域，具有施工成本低、速度快等特点，且解决了混凝土浇筑过程中出现的上浮漂移问题。
