Column beam connecting joint of GFRP pipe, concrete and I-shaped steel composite column
The invention provides a column beam connecting joint of a GFRP pipe, concrete and I-shaped steel composite column. The joint comprises a GFRP pipe, main I-shaped steel, auxiliary I-shaped steel, angle steel and a plurality of high-strength threaded connecting pieces, wherein one end of the main I-shaped steel is embedded in the middle of the GFRP pipe, the other end of the main I-shaped steel protrudes out of the GFRP pipe, concrete is poured between the main I-shaped steel and the GFRP pipe, the angle steel comprises first angle steel and second angle steel, first side plates of the first angle steel and the second angle steel are connected with two auxiliary wing plates of the auxiliary I-shaped steel through the high-strength threaded connecting pieces respectively, and second side plates of the first angle steel and the second angle steel are connected with first main wing plates of the main I-shaped steel through the high-strength threaded connecting pieces respectively. The concrete is in a three-dimensional stress state under the constraint action of the GFRP pipe, so that the strength of the concrete is improved; and the other end of the main I-shaped steel is connected with the auxiliary I-shaped steel through the high-strength threaded connecting pieces, so that adverse effects of welding stress and welding deformation caused by welding on the performance of the joint are avoided, the strength of the joint and the stability of the structure are improved, and good practicability is achieved.
本发明提供了一种GFRP管‑混凝土‑工字钢组合柱的柱梁连接节点，包括GFRP管、主工字钢、副工字钢、角钢和若干高强度螺纹连接件，主工字钢的一端嵌设在GFRP管的中部、另一端凸出于GFRP管，主工字钢和GFRP管之间浇筑有混凝土，角钢包括第一角钢和第二角钢，第一角钢和第二角钢的第一侧板通过高强度螺纹连接件分别连接副工字钢的两个副翼板、第二侧板通过高强度螺纹连接件分别连接主工字钢的第一主翼板；通过GFRP管的约束作用使混凝土处于三向应力状态，从而提高其强度；而利用主工字钢的的另一端与副工字钢通过高强度螺纹连接件进行连接，避免了由于焊接带来的焊接应力以及焊接变形对节点性能的不利影响，增加了节点的强度以及结构的稳定，具备很好的实用性。
