当前,随着农村经济日趋好转,广大农民迫切需要修建房屋,而木材又建不应求。楼板如果采用多孔板,造价较高,吊装也比较困难,不适合农村使用。近年来,有些地方采用了预制小梁,加铺混凝土小块平板,造价虽低,但又存在施工工期长、螺体性差的问题针对这种情况,浙江省东阳、义乌等县试验成功了 At present, with the improvement of the rural economy, the majority of farmers urgently need to build houses, and the construction of timber is not to be done. If the floor plate is made of perforated plates, the construction cost is relatively high, lifting is also difficult, and it is not suitable for rural use. In recent years, prefabricated trabecular beams have been used in some places and slabs of small concrete slabs have been added. Although the construction cost is low, there are problems with long construction period and poor screw properties. In response to this situation, the tests in Dongyang and Yiwu counties in Zhejiang Province were successful.
