Self-formwork cast-in-place floor and construction method thereof
The invention discloses a self-formwork cast-in-place floor and a construction method thereof, and belongs to the technical field of buildings. The floor comprises a steel bar truss which comprises longitudinal and transverse steel bars, triangular overlapping frames and frame-shaped connecting frames, each triangular overlapping frame is composed of six triangles which are integrated and overlapped with one another, each frame-shaped connecting frame is formed by bending a steel bar, a self-formwork system is formed by fixing an inner-layer bottom formwork, an outer-layer bottom formwork and gasket strips on frame arms of the frame-shaped connecting frames in a mutually crossed manner, and the pouring is divided into two steps, and a bottom template for the front pouring is used as a bottom template for the rear pouring. The floor has the beneficial effects that the overall load force of the self-formwork system is increased, the formwork is erected on the whole by means of the structural characteristics of the steel bar truss of the self-formwork system, scaffold supporting is completely omitted, and material cost and labor cost are greatly saved; and the triangular overlapping frames and the frame-shaped connecting frames are adopted, so that the strength of the steel bar truss can be improved, and the triangular overlapping frames and the frame-shaped connecting frames can be used as hoisting and supporting parts of the bottom formwork to provide alternative supporting force for removing a scaffold.
一种自支模现浇楼板及其施工方法，属于建筑技术领域，公开了所述钢筋桁架包括纵横钢筋、三角重叠架和匡形连接架；所述三角重叠架由一体式的互相重叠的六个三角形构成；所述匡形连接架是由一根钢条折弯而成；所述自支模系统由内层底模板、外层底模板和垫片条相互交叉固定在匡形连接架的匡臂上；所述浇注分两步，在前浇注的作为在后浇注的底模板；其有益效果是增加了自支模系统的整体荷载力，整体上利用自身钢筋桁架的结构特点支设模板，完全去掉了脚手架支撑，大大节省了材料成本和劳动力成本；采用三角重叠架和匡形连接架不仅可以增加钢筋桁架的强度，还可以作为底模板的吊拉支撑部件，为去掉脚手架提供替代支持力。
