Plate beam pouring formwork, prefabricated plate beam construction method and bridge construction method
The invention provides a plate girder pouring formwork, a prefabricated plate girder construction method and a bridge construction method. The plate girder pouring formwork comprises a lower formwork body, an upper formwork body and fixing pieces. The lower die plate comprises a lower die body and a die plate guide wheel lower portion connected to the lower die body, an opening is formed in the upper side of the lower die body, and a positioning hole is formed in the length direction of the lower die body in a penetrating mode. The upper mold plate comprises an upper mold main body and a mold plate guide wheel upper part connected to the upper mold main body 210, so that a square mold cavity is formed in the lower mold main body; the lower die body and the upper die body are connected through the fixing piece, so that the upper portion of the die cavity is closed, and meanwhile the lower portion of the template guide wheel and the upper portion of the template guide wheel are in butt joint to form a complete template guide wheel. According to the precast slab beam construction method, a pouring formwork is matched with a centrifugal method to pour concrete to achieve forming of a hollow slab beam, and the problems that the size precision is poor and forming flaws exist when the hollow slab beam is formed are solved.
本发明提供一种板梁浇注模板、预制板梁施工方法及桥梁施工方法，板梁浇注模板包括下部模板、上部模板、固定件；下部模板包括下模主体和连接于下模主体的模板导轮下部，所述下模主体上侧开口，沿所述下模主体长度方向贯穿设置定位孔；上部模板包括上模主体和连接于上模主体210的模板导轮上部，使得所述下模主体内形成方形的模腔；固定件将下模主体和上模主体相连接，使得模腔上部封闭，同时所述模板导轮下部和模板导轮上部对接成一个完整的模板导轮；预制板梁施工方法使用浇注模板配合离心法浇注混凝土实现空心板梁的成型，解决空心板梁成型时尺寸精度差、成型瑕疵的问题。
