Experimental Study on Plug-In Filling Hole for Lap-Joint of Steel Bar of PC Concrete Structure 预制混凝土结构插入式预留孔灌浆钢筋锚固搭接试验研究
This paper describes the major design problems of three layer lap-joint and multi-stage dosing asphalt sprayer and introduces the selection of the domestic truck chassis. 本文对三层搭接多级定量沥青洒布车的设计主要问题加以论述,并介绍如何正确选用国产汽车底盘。
The results shown that a deformation-free joint with good weld surface appearance can be obtained with suitable welding conditions for butt-joint and lap-joint of the dissimilar materials. 结果表明,当焊接工艺参数合适时,可以获得表面成形良好、无变形的铝合金与钢的对接接头和搭接接头。
Results indicate that the fracture positions of two kinds of joints happen on the base metal, except for the lap-joint of brass, which shows better mechanical properties of the joints brazed with the silver filler metal bearing gallium. 结果表明,除黄铜对接形式外,其它形式的接头的断裂位置均在母材上,说明含镓、铟银钎料的力学性能优良。
