焊接梁柱连接在日本已得到广泛应用，但与螺栓连接相比，焊接梁柱连接的缺点之一是难度大，生产速度慢。螺栓连接可能是提高生产速度的另一种方法，但很少有定量和实际数据的报道。本文报道了腹板夹式连接作为螺栓连接之一的制造时间。根据使用腹板夹紧型连接件的实际钢结构建筑施工的工作记录，汇总每个生产步骤的工作时间，并与传统焊接连接件的工作时间进行比较。结果表明，腹板夹紧连接的制造时间比传统焊接连接的估计制造时间少30%，这要归功于零件数量较少和焊接量较少。
Welded beam-to-column connections have been widely used in Japan, however, one of the disadvantage compared to bolted connections is the difficulty and low production speed. Bolted connection may be an alternative way to higher production speed, however, very few quantitative and actual data have been reported. This paper reports the fabrication time for web-clamp type connections as one of the bolted connections. From the work record for an actual steel building construction using the Web-clamped type connections, the work time of each production step was aggregated and compared to that of conventional welded connections. As a result, it was shown that the fabrication time for Web-clamped connections is 30 % less than the estimated fabrication time for conventional welded connection, thanks to the smaller number of parts and the less quantity of welding.
