我厂在省建材科研所的帮助下,研制了预应力粘土空心桁条和预应力粘土空心楼板。经过多年的建筑使用,效果良好。它工艺简单,造价低廉,就地取材,节约水泥,同水泥空心楼板比较,还具有某些优越性。农民用来建房,非常方便。一、空心楼板砖及空心桁条砖的选型这两种砖根据减轻自重,适当提高孔洞率,保证砖的抗压抗剪强度,便于配筋浇灌混凝土
With the help of the Provincial Institute of Building Materials Science and Technology, our factory has developed prestressed clay hollow purlins and prestressed clay hollow floor slabs. After many years of construction, the effect is good. Its simple process, low cost, local materials, saving cement, compared with the hollow concrete floor, but also has some advantages. It is very convenient for farmers to build houses. First, the selection of hollow floor slabs and hollow raft bricks These two types of bricks are based on lightening their own weight, increasing the hole rate, ensuring the compressive shear strength of the bricks, and facilitating the reinforcement of concrete.
