1984年至今,在西安地区,空心砖成了热门货。240×115 ×90毫米承重空心砖(26孔圆孔)和240×240×115毫米非承重空心砖(7孔)供不应求。这同三年前的情况形成鲜明对比。那时,空心砖无人问津,大量积压。空心砖由积压到供不应求,这种变化绝不是偶然的。这是由于: 一、各方通力协作1981年,正当空心砖的发展濒临绝境的时候,原建工总局设计局和原建材部地新局,根据当时国内及西安地区空心砖发展情况,联合下达了《西安地区推广空心砖可行性研究》课题,课题由中国建筑西北设计院负责,并有研究、生产、施工部门参加。这项课题于1981年年底完成。课题报告分析了国内外空心砖发展情况,总结了国内空心砖推广应用的经验和存在的问题,并提出了推广应用空心砖的八项建议;对空心砖的性能进行了一些测试,给推广
Since 1984, hollow bricks have become popular in Xi’an. 240 × 115 × 90 mm load-bearing hollow bricks (26-hole round holes) and 240 × 240 × 115 mm non-load-bearing hollow bricks (7 holes) are in short supply. This contrasts sharply with the situation three years ago. At that time, nobody asked for hollow bricks and there was a huge backlog. From the backlog of hollow bricks to supply, this change is by no means accidental. This was due to: 1. All parties worked together. In 1981, when the development of hollow bricks was on the verge of an impending situation, the original design bureau of the former State Bureau of Construction and Industry and the new bureau of the original building materials division jointly issued the “according to the development of hollow bricks in the domestic and Xi’an regions at the time.” The feasibility study of the promotion of hollow bricks in Xi’an area is under the responsibility of the Northwest Building Design Institute of China Architecture, with the participation of research, production, and construction departments. This topic was completed at the end of 1981. The project report analyzed the development of hollow bricks at home and abroad, summed up the experience and problems of the promotion and application of domestic hollow bricks, and proposed eight proposals for the promotion and application of hollow bricks; some tests were conducted on the performance of hollow bricks to promote them.
