（山東省建筑設(shè)計研究院 濟南 250001）[提要] 簡述了冷拔螺旋鋼筋的各項機械性能及力學性能指標，同時給出預(yù)應(yīng)力冷拔螺旋鋼筋空心板的試驗結(jié)果，另外還分析了開發(fā)冷拔螺旋鋼筋的生產(chǎn)技術(shù)及經(jīng)濟效益。
[關(guān)鍵詞] 冷拔螺旋鋼筋 預(yù)應(yīng)力 空心板All kinds of mechanical properties for the Cold Spirally-drewing Deformed Bar(CSDB) are simply intro-duced, and the test results of the prestressed round-hole slab reinforced with the Cold Spirally drewing Deformed Bar are given. The technology for manufacture and the financial benefit for the development of CSDB are analyzed.
Keywords: Cold Spirally-drewing Deformed Bar; prestress; round-hole slab
