1978年,我国实行改革开放初期,国内房屋建筑水平非常落后,城市里很少有像样的饭店、楼宇,而农村的建筑条件更差。当时,国家想搞新型建材企业,于是,成立了北京新型建材试验厂(北新的前身)。其实,最初引进新型建材是想做房屋,当时推行混凝土预制构件建房子也需要大量建筑材料。那时,北新建材向北京市提供了新型房屋的建筑设计方案,但他们订的很少,还继续沿用传统的砖块堆 In 1978, at the initial stage of China's reform and opening up, the level of domestic housing construction was very backward. There were few decent hotels and buildings in the cities, and the construction conditions in rural areas were even worse. At that time, the state wanted to engage in new building materials enterprises, so set up a new Beijing building materials testing plant (North new predecessor). In fact, the initial introduction of new building materials is to do the housing, then the implementation of concrete prefabricated building houses also need a lot of building materials. At that time, Beijing New Building Materials Co., Ltd. provided the architectural design plan of new houses to Beijing, but they did not subscribe so much and they continued to use traditional brick heaps
