楼梯踏步斜板一般采用翻转脱模工艺成型,后又改在地面生产,这两种方法对质量都无保证。其主要缺点是:砼不密实,与钢筋的握裹力差,构件的承载能力远远达不到设计要求;几何尺寸不准,超长、超宽、超厚严重;底面粘结的砂、石很多,而且工效很低。近年来,我厂为了满足设计和施工要求,消除质量事故,经反复试验研究,解决了构件生产中的通病,达到了保证质量、提高工效、降低成本、减轻劳动强度的目的。具体做法如下: 1.做一个斜坡形固定台座。用砖砌一支墩,在支墩上安放圆孔板或其它平板,用1∶2水泥砂浆抹平
Stair sloping plates are generally formed by flipping and demoulding process, and then changed to ground production. These two methods have no guarantee for quality. The main disadvantages are: the concrete is not dense, and the grip strength of the steel is poor, the bearing capacity of the component is far from the design requirements; the geometrical dimensions are not accurate, the length is long, the width is extraordinarily thick, and the thickness is serious; A lot of stone, and ergonomics is very low. In recent years, in order to meet the design and construction requirements and eliminate quality accidents, our factory has solved the common problems in the production of components through repeated trials and research, achieving the purpose of ensuring quality, improving work efficiency, reducing costs, and reducing labor intensity. The specific approach is as follows: 1. Make a slope-shaped fixed pedestal. Using a brick to form a pier, place a round hole plate or other plate on the pier, and level it with 1:2 cement mortar
