盖房子用木材,这是几千年人们建房的习惯。随着建材技术的发展,现在农村建房所用的梁、檩、椽已可以利用预应力混凝土构件来代替。去年昌图县建筑工程公司在铁岭地区科委、建委的支持下,在我省首先制成了预应力混凝土檩条,这个县当年用这种建房新材料建起民房90间。 Building a house with wood is a habit of building houses for thousands of years. With the development of building materials technology, beams, concretes, and concretes used in rural housing construction can now be replaced with prestressed concrete components. Last year, Changtu County Construction Engineering Co., Ltd., with the support of the Tieling Science and Technology Commission and the Construction Committee, made the prestressed concrete purlins in our province. The county built 90 private houses with this kind of building materials.
