Lattice type rod piece and bolt connection joint for single-layer latticed shell structure and construction and installation method thereof
The invention relates to a lattice type rod piece and bolt connection joint for a single-layer latticed shell structure and a construction and installation method thereof. The lattice type rod piece and bolt connection joint for the single-layer latticed shell structure is composed of a double-limb batten plate lattice type rod piece part and a bolt connection joint part; the double-limb batten plate lattice type rod piece part comprises batten plates and limb rods; the bolt connection joint part comprises a split joint body, a double-section high-strength bolt, a thick nut, a thin nut and an end plate; the adopted double-limb batten plate lattice type rod piece is composed of an upper limb rod, a lower limb rod and a plurality of batten plates, and the portion, with a small stress, in the section of a solid-web rod piece and the section of a closed pipe rod piece is reduced, so that the utilization rate of materials in the rod piece is increased, and under the condition that the bearing capacity is not changed, the dead weight of the single-layer latticed shell structure is reduced; and meanwhile, the lattice type rod piece has a higher bending rigidity, so that when the single-layer latticed shell structure is applied with an external load, the deformation of the rod piece is smaller, and the rigidity and the stability of the structure are improved. The double-limb batten plate lattice type rod piece and the split type joint body are matched with each other, so that the overall weight and the economic cost of the structure are further reduced.
一种单层网壳结构用格构式杆件和螺栓连接节点及其施工安装方法，其由双肢缀板格构式杆件和螺栓连接节点两部分组成，双肢缀板格构式杆件部分包括缀板和肢杆，螺栓连接节点部分包括分体式节点体、双段高强度螺栓、厚螺母、薄螺母、端板；所采用的双肢缀板格构式杆件由上下两根肢杆与多块缀板构成，削减了实腹式杆件截面和闭口管杆件截面中受力较小的部分，提高了杆件中材料的利用率，在承载能力不变的情况下，降低了单层网壳结构的自重；同时，格构式杆件有更大的抗弯刚度，进而单层网壳结构在受外荷载作用时，其杆件的变形更小，提高了结构的刚度和稳定性。双肢缀板格构式杆件与分体式节点体两者相互配合，进一步降低了结构的整体重量及经济成本。
