水泥路面砖作为水泥制品生产中的一个主要产品。就以方砖(250×250×50mm)为例,在沈阳市生产已有30余年的历史,当前年用量在300万块以上。1959年,沈阳首次在中山路三经街口铺设了自己生产的水泥方砖1000m~2,当时制砖方式是用人工夯打,质量不过关。后来改用5t摩擦压力机压制,将铁模具在压力机下推来推去,劳动强度极大。当时沈阳市年铺设方砖达10～20万块,均使用在人行步道上。1965～1966年连续在沈阳南京街铺设了人行步道方砖50万块,从那时起就开始着手进行方砖生产线的机械装置及其自动生产线的研制工作。 Cement pavers are a major product in the production of cement products. Taking a square brick (250×250×50mm) as an example, it has been produced in Shenyang for more than 30 years. The current annual usage is more than 3 million pieces. In 1959, for the first time, Shenyang laid its own 1,000m~2 cement square bricks at Sanjingjie Street of Zhongshan Road. At that time, the brick making method was beaten by hand and the quality was not enough. Later, it was replaced with a 5t friction press to push the iron mold under the press and the labor intensity was great. At that time, Shenyang City laid 1,000 to 200,000 bricks per year, all of which were used on pedestrian walkways. From 1965 to 1966, 500,000 pedestrian walkway bricks were laid on Nanjing Street in Shenyang. Since then, work on the production of mechanical devices for the brick production line and its automatic production lines has begun.
