大型劲性混凝土梁拉筋连接技术

Connection of the Tied Reinforcement for Large SRC Beam

珠江新城L3-1,L3-3地块项目工程在第4层转换层设置劲性混凝土梁,采用在工字钢腹板设置拉筋连接板连接拉筋的施工方法,解决了削弱工字钢腹板抗弯能力、施工难度大的问题。与传统的拉筋连接技术相比,突出该技术的创新点,并详细介绍其拉筋连接的施工工艺和操作要点。该施工技术操作简单方便,缩短了由于在腹板预留孔穿插带钩拉筋花费的时间,节约了工期。

The SRC beam was designed at the transfer story in the fourth layer of the L3-1, L3-3 engineering of Zhujiang New Town. The construction technology of connecting the tied reinforcement by setting the connecting plate has successfully solved the special problems to bending resistance of the section steel web and construction difficulty. Compared with traditional connection technology of tied reinforcement, the prominent innovative points of the construction technology of the connection of tied reinforcement for large SRC beam were obtained, and the construction technology and operation points of the connection of tied reinforcement are described in detail. The operation of the construction technology is simple and saves construction period.
