String structure, string beam and building

Abstract

The invention discloses a string structure, a string beam and a building. According to the string structure, tensioned stay rope components are adopted as basic components. Stay ropes are building components frequently used at present, conventionally, the structure weight of the stay ropes is greatly reduced compared with that of rigid components used for rigid beams, certain supporting capability can be formed through tensioning, the supporting capability can be effectively improved in cooperation of the composite structure of upper string ropes and lower string ropes, and thus a light roof such as a thin film roof can be supported; by means of the structure, the influence of the self-gravity capability on the span is greatly relieved under the influence of the tensioning resisting capability of the stay ropes, and thus the span of the string beam can be relatively increased.

Description

technical field [0001] The invention relates to a string tension structure, a string tension beam and a building. Background technique [0002] At present, facilities with large-span ceilings and roofs, such as factories, large-scale open vegetable markets, and temporary parking lots with large-span ceilings, generally have brick-wood structures, brick-concrete structures, reinforced concrete structures, or steel structure. Such structures generally use beams as the basic structure such as the roof, and then build other auxiliary facilities according to the basic structure. Affected by the relatively large weight of the beam and its own rigidity, for example, the span of the roof will be greatly restricted. In addition, even for steel structures with relatively fast construction speed, the construction period will still be relatively long, and the requirements for the foundation are relatively high. [0003] In order to meet the needs of existing civil engineering for lon...
