Novel composite material pultrusion profile truss node and construction method thereof
The invention discloses a novel composite material pultruded profile truss node and a construction method thereof, relates to the technical field of building construction, and aims to solve the problems that a composite material pultruded profile fabricated structure system node is complex in connection process, poor in integrity and low in connection efficiency. The connecting structure comprises a profile rod piece, a U-shaped steel sleeve and a transverse connecting steel sleeve, wherein the profile rod piece comprises an upper chord, an inclined supporting rod and a vertical rod; the U-shaped steel sleeves wrap the connecting points of the upper chord, the diagonal bars and the vertical bars and are fixed through high-strength bolts; the transverse connection steel sleeves are installed on the left side and the right side of the U-shaped steel sleeve, and transverse connection transverse rods and inclined rods are embedded in the transverse connection steel sleeves. The U-shaped steel sleeve connecting piece is adopted instead of two separated gusset plates, so that the joint has better overall rigidity and torsion resistance, the stress area of bolt pretightening force is enlarged, the hole periphery stress during bolt pretightening is effectively reduced, meanwhile, the tedious bolt gasket mounting procedure is omitted, and the production efficiency is improved. And the initial damage of the profile rod piece due to the action of the pre-tightening force of the bolt is avoided.
本发明的一种新型复合材料拉挤型材桁架节点及其施工方法，涉及建筑施工技术领域，用于解决复合材料拉挤型材装配式结构体系节点连接工艺复杂、整体性差、连接效率低的难题。它包括型材杆件、U型钢套以及横向联系钢套，型材杆件包括上弦杆、斜撑杆和竖杆；U型钢套包裹于上弦杆、斜撑杆和竖杆的连接点处，并通过高强螺栓固定；横向联系钢套安装于U型钢套的左右两侧，横向联系钢套上嵌设有横向联系横杆和斜杆。采用U型钢套连接件而非两块分离的节点板，使得节点具有更好的整体刚度和抗扭性能，扩大了螺栓预紧力的受力面积，有效减小螺栓预紧时的孔周应力，同时省去了繁琐的螺栓垫片安装工序，且避免因螺栓预紧力的作用使型材杆件发生初始损伤。
