To achieve these goals, technical solution of the present invention is: the job practices of a kind of removal-free ater-casting, may further comprise the steps: (one) arranges left horizontal skeleton within structure to be cast needs to arrange the cross section of position high order end of ater-casting, left vertical skeleton, make left horizontal skeleton, the structure reinforcing bars of left vertical skeleton and structure to be cast fixes, and left horizontal skeleton intersects mutually with left vertical skeleton, within structure to be cast needs to arrange the cross section of position low order end of ater-casting, right horizontal skeleton is set, right vertical skeleton, make right horizontal skeleton, the structure reinforcing bars of right vertical skeleton and structure to be cast fixes, and right horizontal skeleton intersects mutually with right vertical skeleton, (2) at left horizontal skeleton, left vertical skeleton left side arranges left steel fabric sheet, at right horizontal skeleton, right vertical skeleton right side arranges right steel fabric sheet, make left steel fabric sheet and left horizontal skeleton, left vertical skeleton mutually against, right steel fabric sheet and right horizontal skeleton, right vertical skeleton mutually against, and make a left side, right steel fabric sheet is full the shop in the cross section of structure to be cast, on a left side, form the ater-casting between the right steel fabric sheet.
The job practices of removal-free of the present invention ater-casting, wherein, described left horizontal skeleton is at least two, wherein the structure reinforcing bars with the superiors fixes, another root and undermost structure reinforcing bars fix, and each left horizontal skeleton all is parallel to each other with horizontal plane, and each left vertical skeleton is arranged in order along the width of structure to be cast, each left vertical skeleton interfix with left horizontal skeleton and each vertical skeleton in a left side and each left horizontal skeleton perpendicular.
The job practices of removal-free of the present invention ater-casting, wherein, the differing heights place of described each left horizontal skeleton in the cross section of structure to be cast is arranged in order, and the distance between the adjacent two left horizontal skeletons is 300-500mm.
The job practices of removal-free of the present invention ater-casting, wherein, described right horizontal skeleton is at least two, wherein the structure reinforcing bars with the superiors fixes, another root and undermost structure reinforcing bars fix, and each right horizontal skeleton all parallels with horizontal plane, and each right vertical skeleton is arranged in order along the width of structure to be cast, each right vertical skeleton interfix with right horizontal skeleton and each vertical skeleton in the right side and each right horizontal skeleton perpendicular.
The job practices of removal-free of the present invention ater-casting, wherein, the differing heights place of described each right horizontal skeleton in the cross section of structure to be cast is arranged in order, and the distance between the adjacent two right horizontal skeletons is 300-500mm.
The job practices of removal-free of the present invention ater-casting, wherein, the distance between the vertical skeleton of the distance between the vertical skeleton in adjacent two described left sides and the adjacent two described right sides is 200-400mm.
The job practices of removal-free of the present invention ater-casting, wherein, the aperture of described left and right steel fabric sheet mesh is 5mm.
After adopting such scheme, the job practices of removal-free of the present invention ater-casting is owing to arranging left and right steel fabric sheet at the left and right two ends that structure to be cast needs the position, ater-casting is set, not only work progress is simple, easy to operate, can avoid spillage, and can be directly at ater-casting part fluid concrete after the concrete of formerly building part fully is out of shape, free removal saves time, laborsaving, and drops at the concrete easy to clean of ater-casting part.
