（中國建筑標(biāo)準(zhǔn)設(shè)計(jì)研究院，北京100048）[摘要] 介紹了國標(biāo)圖集《型鋼混凝土結(jié)構(gòu)施工鋼筋排布規(guī)則與構(gòu)造詳圖》的主要內(nèi)容，包括現(xiàn)澆型鋼混凝土梁、柱、剪力墻、基礎(chǔ)等構(gòu)件的施工鋼筋排布規(guī)則與構(gòu)造詳圖。該圖集針對型鋼混凝土結(jié)構(gòu)工程中，一直困擾工程人員的鋼筋與型鋼的排布難題進(jìn)行編排。重點(diǎn)介紹了型鋼混凝土框架節(jié)點(diǎn)鋼筋與型鋼的四種連接方式：牛腿焊接法、繞筋穿孔法、套筒連接法和短鋼梁搭接法。并根據(jù)已有的試驗(yàn)研究成果和工程實(shí)踐調(diào)研，從抗震性能、施工難易程度和經(jīng)濟(jì)性方面對四種連接方式進(jìn)行對比分析。推薦牛腿焊接的連接方式作為型鋼混凝土框架節(jié)點(diǎn)鋼筋連接的首選做法。[關(guān)鍵詞] 型鋼混凝土結(jié)構(gòu); 鋼筋排布; 國標(biāo)圖集; 牛腿焊接中圖分類號：TU398+.2 , TU318.4 文獻(xiàn)標(biāo)示碼：A 文章編號：1002-848X(2013)S2-0512-05作者簡介：彭明英，碩士，一級注冊結(jié)構(gòu)工程師，Email：1109282009@qq.com。Introduction of Arrangement rules and construction details of rebars in the SRC structurePeng Mingying, Jiang Hangjun, Zhang Linzhen, Yu Yinquan(China Institute of Building Standard Design & Research, Beijing 100048, China)Abstract: The main content of this standard atlas——Arrangement rules and construction details of rebars in the SRC structure was introduced, including cast-in-place SRC members such as beams, columns, shear wall and bases. The purpose of this atlas is to solve the difficulty of arrangement between rebars and section steel, which is very troublesome for engineering staff all the time. It focuses on the four connection types of rebars and section steel in SRC frame joints: welding by bracket, bending the rebars and through the holes in section steel, connecting by rebar connecters, and connecting by steel beams. Moreover, the four connection types were compared in three aspects: seismic performance, the degree of difficulty in construction, and economical efficiency, basing on existing test results and practice investigation in construction. And the method of welding rebars by bracket on section steel is recommended for the first choice.
Keywords: SRC structure; arrangement rules of rebars; standard atlas; welding by bracket
