Cast-in-place concrete large-size core formwork hollow floor anti-floating structure and construction method
The invention discloses a cast-in-place concrete large-size core formwork hollow floor anti-floating structure and a construction method. The cast-in-place concrete large-size core formwork hollow floor anti-floating structure comprises a formwork and a support, wherein an upper-layer reinforcing mesh and a lower-layer reinforcing mesh are arranged on the formwork, a plurality of core formworks are arranged between the upper-layer reinforcing mesh and the lower-layer reinforcing mesh, anti-floating steel bars are arranged between the upper-layer reinforcing mesh and the core formworks, the anti-floating steel bars are horizontally placed on the plurality of core formworks, vertical rods are perpendicular to the anti-floating steel bars mutually, positioning pieces are arranged on one endsof the vertical rods towards the anti-floating steel bars in an extending mode, threaded ends are arranged on the other ends of the vertical rods towards the formwork in an extending mode, bearing rods are arranged on the outer walls of the vertical rods, a plurality of through holes are formed in the formwork, the plurality of through holes are in one-to-one correspondence with the vertical rods,and connecting pieces are detachably arranged on the through holes. According to the cast-in-place concrete large-size core formwork hollow floor anti-floating structure and the construction method,the problems that in the prior art, a large-size core formwork hollow floor structure floats upwards in construction, and a large amount of labor is consumed for core formwork fixing and iron wire cleaning in a traditional construction technology are solved.
本发明公开了一种现浇混凝土大尺寸芯模空心楼盖抗浮结构及施工方法，包括模板和支架，模板上方设置有上层钢筋网和下层钢筋网，上层钢筋网和下层钢筋网之间设置有若干个芯模，上层钢筋网与芯模之间设置有抗浮钢筋，抗浮钢筋平放在若干个芯模上，相邻芯模之间均设置有立杆，立杆与抗浮钢筋互相垂直设置，立杆一端向抗浮钢筋方向延伸有定位件，另一端向模板方向延伸有螺纹端，立杆外壁上设置有马凳筋，模板上开设有若干个透孔，若干个透孔均与若干个立杆一一对应，透孔上可拆卸设置有连接件。本发明解决了现有技术中大尺芯模空心楼盖结构在施工中上浮且传统的施工技术中耗费大量人工用于芯模固定及铁丝清理的问题。
