混凝土用建筑锚栓拉伸承载力影响因素的试验分析

Analysis of main factors influencing the ultimate tensile capacity of building anchor

本文对埋置于混凝土中的建筑锚栓(膨胀摩擦型锚栓)进行了拉伸试验,分析了影响膨胀摩擦型锚栓极限荷载的因素(锚栓的锚杆直径。锚栓的埋深、混凝土的强度),以及拉伸极限荷载随各因素的变化情况。

The building anchors (expansion anchor) em- bedded in the concrete and subjected to the concentrated tension load are studied in this paper. Main factors (the diameter of anchors, the depth of fixing, the strength of concrete) influencing the ultimate tensile load of expan- sion anchor have been discussed. The change of the ulti- mate load factor have also been discussed.
