钢筋挤压连接是用特别的钢套筒,将连接的两根钢筋套在一起,通过挤压机和钢模具,将套筒挤压变形,使之咬住变形钢筋的横肋,从而使两根钢筋与变形后的套筒连为一体,形成可靠的钢筋连接接头。钢筋挤压连接法有以下特点: 1.接头性能可靠。接头的静载拉伸试验,断裂处在母材,在钢筋弹性极限内加载后的永久应变量小于0.3％。模拟地震荷载作用下的变应力重复。试验结果为接头强度及刚度大于母材。残余变形量为0.045～0.190mm<0.3mm,上述指标完全符合日本土木学会标准《钢筋评价指南》和
Rebar extrusion connection is a special steel sleeve, the two connected to the two sets of steel sleeve, through the extruder and the steel mold, the sleeve extrusion deformation, so that bite deformation of the transverse ribs, so that the two The root reinforcement is connected to the deformed sleeve to form a solid reinforced connection. Reinforced extrusion connection has the following characteristics: 1. Connector performance and reliable. Static load tensile test joints, broken in the base metal, within the elastic limit of steel loaded permanent strain less than 0.3%. Simulated earthquake stress repeated stress. The test results for the joint strength and stiffness greater than the base metal. Residual deformation of 0.045 ~ 0.190mm <0.3mm, the above indicators in full compliance with Japan Society of Civil Society “Guidelines for the evaluation of steel” and
