Embodiment 1

[0023] to solve figure 1 According to the design and use of the structural system shown, the embodiment of the present invention provides a combined node of a fully tensioned cross-cable truss structure, such as figure 2 As shown, the upper node is composed of main cable groove 6, secondary cable groove 7, rubber block A501, rubber block B502, base 4, cover plate 8, nut A1501 and nut B1502; the lower node is composed of upper cable groove 11, lower cable Groove 12, gasket 9, rubber layer A1001, rubber layer B1002, disc spring 17, anchor plate 13, anchor clamp 14 and nut C16.

[0024] Such as image 3 As shown, the lower surface of the main cable groove 6 has a strip-shaped groove that can be embedded in the cable in one direction of the upper string cable 1; the lower surface of the secondary cable groove 7 has a strip-shaped groove that can be embedded in the upper string The cable in the other direction in the cable 1; the upper surface and the lower surface of the main c...

Abstract

The invention provides a tension self-adjusting type combined joint for a full-tension crossed cable truss structure, and belongs to the field of large-span space structure design. An upper joint body is composed of a main cable groove, an auxiliary cable groove, a rubber block, a base, a cover plate and a nut A; a lower joint body is composed of an upper cable groove, a lower cable groove, a gasket, a rubber layer, a belleville spring, an anchor plate, an anchoring clamp and a nut B; crossed horizontal inhaul cables can penetrate through the upper joint body and the lower joint body, the main cable groove and the auxiliary cable groove can rotate relatively, the upper cable groove and the lower cable groove can rotate relatively, and the crossed angle of the inhaul cables is adjusted; the upper end of a vertical inhaul cable is fixed to a lug plate of the base of the upper joint body, and the lower end of the vertical inhaul cable penetrates through all the components of the lower joint body and is anchored through the anchoring clamp at the bottom of the anchor plate; and the belleville spring is installed on the lower joint body, the pressure borne by the belleville spring is kept the same as the tension of the vertical inhaul cable all the time, and the cable force in the vertical inhaul cable can be automatically adjusted. The combined joint is simple in structure, easy to assemble, capable of automatically adjusting the cable force of the vertical inhaul cable, convenient to construct and install, high in construction safety degree and low in construction cost.

Description

technical field [0001] The invention relates to a tension force self-adjusting combined node for a fully tensioned cross cable truss structure, which belongs to the field of large-span space structures. Background technique [0002] A new type of space structure system - fully tensioned cross-cable truss structure without inner ring (patent publication number CN109629690A), its structural force is different from that of the traditional tensioned overall structure in the "ocean of cables and struts (compression bar) )'s design concept, all use cables to realize the establishment of the overall structural system. Therefore, the design of nodes is also different from the characteristics of node compression in traditional space cable structure systems. The nodes of the new fully-tensioned cross-cable truss need to meet three conditions: first, the upper node is subjected to the tension of the upper chord cable and the vertical stay cable, that is, the upper node must have suffic...
