| 摘要 | PURPOSE:To prevent a concrete product from generating the color shade by providing a support head section, a sinkage preventive section, and a floating preventive section on an adherence preventive spacer for separating products when stacking and drying concrete panels. CONSTITUTION:An adherence preventive spacer of a concrete product is provided with a support head section 1 for supporting concrete products stacked above, a sinkage preventive section 2 is formed below the support head section 1, and a floating preventive section 5 is provided below the support head section 1. When vibration processing is applied to the formwork F of cement C installed in the formwork F, the adherence preventive spacer sinks in the cement C and the lower end section of the support head section 1 is submerged in the cement C. In this case, a brake is applied by the sinkage preventive section 2 and the tapered face 6 of a thrust section 4, and an abrupt descent is prevented. In addition, a rise is prevented by the floating preventive section 5, thus the projection condition of the support head section 1 is invariably made uniform. | ||||||
