摘　　要：在桥梁工程建设中,混凝土梁支架法现浇施工常采用的支架结构有满堂支架、梁式支架和混合支架3种。此文在阐述这3种支架结构形式及适用范围的基础上,通过对4座已建桥梁工程采用不同类型支架现浇法施工的研究,以及对所用支架用钢量的统计与分析,通过计算得出每立方米空间所用支架的用钢量指标。采用满堂支架时,用钢量指标为32.53 kg/(m3空间);采用梁式支架时,用钢量指标为37.16kg/(m3空间);采用混合支架时,用钢量指标为36.45 kg/(m3空间)。对编制行业和企业定额、施工组织设计和测算项目成本具有一定的参考作用。In the construction of bridge engineering, there are 3 kinds of bracket structure that full framing, beam framing and composite framing used in the cast - in - place construction with concrete beam scaffolding method. On the basis of expounding the 3 kinds of bracket structure forms and scope of application, through the study on 4 bridge engineering using different types of cast - in - place construction with con- crete beam scaffolding method and the statistics and analysis of steel quantity used in the bracket, the steel quantity use index of the bracket in per cubic meter of space. Using full framing, steel quantity in- dex is 32.53 kg/（ m3 space） ; Using beam bracket, steel quantity index is 37.16 kg/m3 space ; Using composite framing, steel quantity index is 36.45 kg/（m3space）. It has reference function for preparing the industry and the enterprise quota, construction organization design and calculating project cost.
