这是适用于建筑工程混凝土试件或类似试件预制块生产的充气式脱模装置,由塑料制成,重量不到铸铁模具的五分之一。其优点是:制作的混凝土试件不变形、不跑模、不掉边,表面平整;试件脱模的工序减少,平均约10s就可将试件脱出;无需拆模装模,没有敲击损伤。又因试模用塑料制成,内外表面光洁,不生锈,有利于脱模后的清洗。现场
This is an inflatable demoulding device suitable for the production of prefabricated concrete specimens of construction engineering or similar specimens. It is made of plastic and weighs less than one-fifth of that of cast iron. The advantages are: the produced concrete specimen is not deformed, does not run the mold, does not drop the edge, the surface is flat; the demoulding process of the test piece is reduced, and the test piece can be taken out in an average time of about 10 seconds; damage. Because the trial mold is made of plastic, the inner and outer surfaces are smooth and free from rust, which is conducive to cleaning after demoulding. on site
