近年来小型混凝土空心砌块在我国得到迅速发展。这种砌块建筑是一种技术经济指标可以与普通砖混建筑相媲美的建筑体系,也是世界各国发展较快的适用建筑技术之一。自七十年代以来,随着砌块需要量的增加,各种砌块生产设备也跟着发展起来。到1984年的南宁全国小砌块成型机评选会时,已有23种机型,蔚为大观。十几年来我国主要采用移动式成型机生产砌块。由于该种生产工艺投资少,技术上要求不高,建厂周期短,见效块,而
In recent years, small concrete hollow blocks have developed rapidly in China. This kind of block building is a kind of building system with technical and economic indicators comparable to ordinary brick and concrete buildings, and it is also one of the fastest-growing applicable building technologies in the world. Since the 1970s, with the increasing demand for blocks, a variety of block production equipment has also developed. By the time of the Nanning National Small Block Molding Machine Selection Competition in 1984, there were already 23 types of machines, making it a grand occasion. For more than a decade, China has mainly used mobile molding machines to produce blocks. Because of the low investment in the production process, the technical requirements are not high, the construction period is short, and the effective block is
