Technical Field

The utility model belongs to the technical field of building construction, and particularly relates to a temporary separation device for pouring concrete with different grades.

Background

In actual building construction, the strength grades of the concrete used by the wall plate beams and the columns are different, and the difference between the strength grades of the concrete of a large number of columns and beams exceeds the strength of two labels. The concrete is classified into different grades of concrete such as C20, C25, C30, C35, C40, C45, C50, C55, C60, C80 and the like according to strength. When the concrete marks of the same part, such as the junction of the wall beam and the plate of the frame structure, are different by two or more, measures are required to be taken for separation.

The traditional concrete separation method is that a steel wire mesh is used for intercepting, the steel wire mesh is bound on the lower row of reinforcing steel bars and the upper row of reinforcing steel bars, and concrete with high strength is poured firstly during pouring. This practice has several disadvantages: firstly, waste manual work, the installation is inconvenient, needs the hand to reach the reinforcing bar of arranging down and carries out the ligature, and the ligature is not in place in the place that the reinforcing bar is very dense and roof beam slab thickness is thicker. Secondly, the gap is very much, and bottom and limit portion can't be sealed, when pouring high-grade concrete, a large amount of cement paste flows to region around, causes the concrete impression quality poor after the form removal, and extravagant high-grade concrete.
