液压滑模施工中对混凝土脱模强度有一定的工艺上的要求,以保证模板滑升时摩阻力较小,避免拉裂混凝土,同时要求滑出模板的混凝土具有足以支承自重、保持形状不变的强度,且不流淌和坍落,还要易于表面抹光。目前,判定混凝土适宜的脱模强度的方法,归纳起来大致有以下几种:1.按指印法:这是一种经验判断的方法,也有以8号铅丝插试者。这类方法的主
Hydraulic slip form construction has certain technical requirements for the demolding strength of concrete to ensure that the frictional resistance when the template is slipping is small, so as to avoid cracking the concrete. At the same time, it is required that the concrete that slides out of the formwork is sufficient to support its own weight and keep its shape unchanged. The strength, and does not flow and fall, but also easy to wipe the surface. At present, the method for judging the suitable demoulding strength of concrete can be summed up in the following ways: 1. Fingerprinting method: This is an empirical judgment method. There are also lead wire inserters. The master of this method
