Hollow floor slab structure and construction method thereof
The invention discloses a hollow floor slab structure and a construction method thereof.The hollow floor slab structure comprises a plurality of longitudinal steel bars and a plurality of transverse steel bars, the longitudinal steel bars and the transverse steel bars are laid on a formwork in a cross grid shape, the longitudinal steel bars are all arranged in the length direction, and every two adjacent longitudinal steel bars are arranged at intervals in the width direction; a plurality of ribbed beam steel bars are preferably arranged at the upper end of the lower reinforcing mesh in a cross grid shape, and the upper end space of the lower reinforcing mesh is divided into a plurality of blank spaces by the ribbed beam steel bars; metal hollow core molds are arranged in the blank spaces, elastic toggle clips are arranged on the two sides of the lower end face of each metal hollow core mold in the width direction, and the distance between the two elastic toggle clips in the width direction is equal to the distance between the two adjacent longitudinal steel bars located in the blank spaces in the width direction; and the relative lower end of the elastic toggle clip is provided with an opening which is smaller than the longitudinal steel bar in size and is used for clamping the longitudinal steel bar. The metal hollow core mold is stable in positioning and does not move during concrete pouring, and the quality of a hollow floor slab structure manufactured through construction is ensured.
本发明公开了一种空心楼板结构及其施工方法，其中空心楼板结构包括用于呈十字网格状铺设在支模板上的多个纵钢筋和多个横钢筋，纵钢筋均平行于长度方向布置，且相邻两个纵钢筋沿宽度方向间隔布置；下部钢筋网的上端呈十字网格状优选布置有多个肋梁钢筋，肋梁钢筋将下部钢筋网的上端空间分隔成多个空格；空格内设有金属空心芯模，每个金属空心芯模的下端面沿宽度方向两侧分别设有弹性夹扣，两个弹性夹扣沿宽度方向的间距与位于空格内的相邻两个纵钢筋沿宽度方向的间距相等；弹性夹扣的相对下端设有尺寸小于纵钢筋尺寸的开口，且用于卡入纵钢筋。本发明的金属空心芯模定位稳定，在混凝土浇筑时不产生移动，确保施工制得的空心楼板结构的质量。
