Construction method for assembling formwork-removal-free prefabricated part
The invention discloses a construction method for assembling a formwork-removal-free prefabricated part. The prefabricated part comprises a cast-in-place area, a plurality of groups of transverse steel bars and a plurality of groups of longitudinal steel bars, wherein the bottoms and the tops of the longitudinal steel bars extend out of concrete of the prefabricated part, and the cast-in-place area is formed in a way that an inner formwork block with a concave-convex structure on the surface is embedded in the prefabricated part. The method comprises the steps of adjusting the elevation of a lower prefabricated part, and lifting an upper prefabricated part to the position above the lower prefabricated part; controlling the upper prefabricated part to fall down, so that the top longitudinal steel bars of the lower prefabricated part extend into the bottom cast-in-place area of the upper prefabricated part, wherein the upper ends of the top longitudinal steel bars of the lower prefabricated part are of first closed structures, and the lower ends of the longitudinal steel bars of the upper prefabricated part are of second closed structures, so that the first closed structures and the second closed structures form a ring anchor; and erecting a cast-in-place formwork after all the steel bars are bound, and pouring concrete into the cast-in-place area of the upper prefabricated part, so that the cast-in-place area and the space between the upper and lower prefabricated parts are filled with concrete.
本发明公开一种免拆模预制构件装配的施工方法，预制构件包括现浇区、多组横向钢筋和多组纵向钢筋，纵向钢筋底部和顶部分别从预制构件的混凝土中伸出；表面具有凹凸结构的内模块嵌在预制构件内形成现浇区，方法包括：调整好下层预制构件标高，起吊上层预制构件到下层预制构件上方；控制上层预制构件下落，使下层预制构件顶部纵向钢筋伸入到上层预制构件底部现浇区中，下层预制构件顶部纵向钢筋上端为第一封闭式结构，上层预制构件纵向钢筋下端为第二封闭式结构，以使第一封闭式结构和第二封闭式结构形成环锚；完成各钢筋绑扎后，支设现场浇筑模板，向上层预制构件现浇区内浇筑混凝土，使混凝土填充到现浇区内和上下层预制构件之间的空间。
