所谓“跳块法”施工,就是在混凝土路面(或整体式水磨石楼地面)分块支模(或嵌条)后,浇一块、跳一块地施工,让先浇筑的分块提前收缩。与分条连续浇筑法相比,跳块法的缺点是:1.支拆模板的工作量增加。按规定,路面的横向伸缝才需要上下贯通;而数量居多的横向缩缝,则无需贯通。采用分条连续浇筑法施工,是先将伸缝的填缝板预先埋入;缩缝可在浇筑后锯开,因而可以省去横向支模(仅头
The so-called “jump block method” construction is the concrete block (or integral terrazzo floor) after the block mold (or molding), pouring a piece, jump piece of land construction, so that the first pouring block early contraction. Compared with the strip continuous casting method, the disadvantages of the skip block method are: 1. The workload of the stripping template increases. According to the regulations, the horizontal stretch joints of the road surface need to pass through up and down; and the transverse shrinkage joints with the most quantity do not need to penetrate. In the continuous casting method, the joints of the joints are pre-embedded; the shrink joints can be sawed after being cast, so that the transverse formwork (head only) can be omitted.
