Nomadic lightweight lifting belt dome structure

Abstract

The invention discloses a nomadic lightweight lifting belt dome structure. The nomadic lightweight lifting belt dome structure mainly comprises a peripherally-pressed truss part erected by ring lock type steel pipe scaffolds, and a lifting belt dome system part composed of lifting belt dorsal cords, lifting belt oblique cords, lifting belt ring cords and aluminum alloy supporting rods. The peripherally-pressed truss part is erected by the ring lock type steel pipe scaffolds. The upper ends of the aluminum alloy supporting rods in a dome are connected with the lifting belt dorsal cords and the lifting belt oblique cords through double-layer splint type joints, and the lower ends of lifting belts are connected with the same-ring supporting rods in a closed mode. The supporting rods are prefabricated from aluminum alloy and assembled on site through hinge joints. Through tensioning of the lifting belt oblique cords or ring cords, pre-tension is established in the whole structure, and the form belongs to whole-tension structural forms. The overall structure can be rapidly spliced and formed on site; construction is convenient and rapid, and high rigidity and the large span are achieved after the structure is formed; the overall mass of the structure is low, transportation and storage are convenient, and the structure can be repeatedly disassembled and assembled multiple times; the structure can be applied to temporary structures such as nomadic industrial plants, greenhouses, temporary shelters and field hospitals, and has high practical significance.

Description

technical field [0001] The invention discloses a nomadic light hoisting belt dome structure, belonging to the technical field of civil engineering space structures. Background technique [0002] As one of the main structural types of space structures, the cable dome structure has the advantages of large span, light weight, full use of material strength, high degree of structural prefabrication, high efficiency and environmental protection of on-site construction, and has been widely used in practical engineering fields. In the fields of disaster relief and field operations, it is often necessary to build large-scale simple tents in the field to meet the functional needs of accommodation, material storage, field hospitals, and combat command. At present, the indoor space that can be built by simple tents is limited, and it is increasingly difficult to meet the needs of temporary shelters and field hospitals. Key technical issues that need to be resolved urgently. Contents ...

AI Technical Summary

Problems solved by technology

[0003] The invention solves the problem that the conventional cable dome structure cannot be quickly installed and formed in the field, and the construction is complicated, and proposes a new nomadic tension structure—a nomadic light-duty hoisting belt dome structure, which has the advantages of a traditional cable dome with a large space span At the same time, it has the advantages of convenient transportation, quick disassembly and assembly, and efficient construction on site, and can create a large-span space suitable for various production and living in a short period of time
