我部有关单位遵照伟大领袖毛主席关于“独立自主,自力更生”和“洋为中用”的教导,根据国外关于“双钢筋”技术资料的介绍情况,对该项技术做了少量授核性试验。试验结果表明:“双钢筋”是一种发挥冷拔中倔碳钢筋在混凝土中有效强度的较好措施,它不需预应力设备,可用作主筋,也可用作架立筋和构造筋,在节约钢材方面有较明显的效果。由于可以盘卷供应,只有单向弯曲,所以调直、运输均较简便,一般工地都可解决,适应面广。据了解奥地利这方面采用的较早。因此本刊介绍有关奥地利等国家应用的部分情况,以供借鉴。——编者 The relevant units of our Ministry have followed the guidance of the great leader Chairman Mao on “independence, self-reliance and self-reliance” and “foreign use,” and according to the introduction of technical data on “double steel bars” in foreign countries, this technology has been A small amount of nuclear test. The test results show that: “double steel bar” is a better measure to exert the effective strength of carbon steel in cold drawn concrete in concrete. It does not require prestressing equipment and can be used as main reinforcement, and can also be used as erection reinforcement. Constructing ribs has obvious effects in saving steel. Because it can coil supply, only one-way bending, so straighten, transport are more simple, the general site can be resolved to adapt to a wide range. It is understood that Austria used this earlier. Therefore, the journal introduces some aspects of application in Austria and other countries for reference. --editor
