Concrete formwork
The invention relates to a concrete formwork. The concrete formwork comprises a panel and a main framework abutting against the outer surface of the panel; the main framework comprises vertical keelsand transverse keels which are arranged in a mutually orthogonal mode; the upper ends of the vertical keels are fixed to the vertical keels at the opposite side through a first counter-pull rod; the lower ends of the vertical keels are fixed to a poured structure through a second counter-pull rod and a third counter-pull rod which are coaxially connected; and the third counter-pull rod is pre-buried in the poured structure. The upper ends of the vertical keels are fixed to the vertical keels at the opposite side through the first counter-pull rod, so that the stability of the upper end of theformwork without internal pull rods is guaranteed; and the third counter-pull rod is pre-buried in the poured structure of the formwork, and the second counter-pull rod and the third counter-pull rodare coaxially connected, so that a force of post-poured non-solidified concrete in the formwork on the formwork can be continuously generated between the second counter-pull rod and the third counter-pull rod, and the situation that the formwork is loosened and leaks is avoided.
本发明涉及一种混凝土模板，其包括面板和抵靠在面板外表面的主骨架，所述主骨架包括相互正交布设的竖向龙骨和横向龙骨，所述竖向龙骨的上端通过第一对拉杆与对侧的竖向龙骨固定；所述竖向龙骨的下端通过同轴连接的第二对拉杆和第三对拉杆与已浇筑结构固定，其中，所述第三对拉杆预埋在已浇筑结构内。竖向龙骨的上端通过第一对拉杆与对侧的竖向龙骨固定，即保证无体内拉杆的模板上端的稳定性，第三对拉杆预埋在模板已浇筑的结构内，并将第二对拉杆与第三对拉杆同轴连接，使得第二对拉杆和第三对拉杆之间能够产生连续的对抗模板中后浇筑的未凝固的混凝土对模板的力，避免模板松脱、出现渗漏的状况。
