Description

Technical Field

[0001] The utility model relates to the technical field of building ceilings, in particular to a ceiling structure combining a tensioned membrane and a steel frame. Background Art

[0002] Steel frame roof is a roof system that uses steel structure as the main load-bearing component. It is usually composed of steel beams, steel columns, steel purlins and other components, and is assembled by welding or bolting. Steel has high strength and rigidity and can withstand large loads. Steel frame roof can achieve a large span design and is suitable for large buildings and places that require open space. However, steel frame roofs usually use metal roof panels, which are more expensive. At the same time, if lighting is required from the roof, additional structures such as skylights must be installed.

[0003] Tensile membrane roof is a common building structure, widely used in underground parking entrances and exits, large outdoor parking sheds and other occasions that require sunshade and rain protection. This structure is mainly composed of tensile membrane materials and supporting structures. The tensile membrane roof structure has the following advantages: (1) The design of the tensile membrane roof is flexible and diverse, and can be personalized according to different needs; (2) Compared with traditional concrete or steel structures, the tensile membrane roof is lighter and weighs only about 1 / 30 of the traditional structure, which makes it more convenient and quick during construction and installation, and also reduces the bearing requirements of the foundation; (3) Due to the light weight and low material consumption of the tensile membrane roof, the cost can be effectively reduced during the construction process; (4) Due to its light weight and high material strength, the tensile membrane roof can achieve a large span of coverage space. However, due to the lightness and flexibility of the tensile membrane roof structure, it is more sensitive to wind loads. In strong winds, it may vibrate or shake, and corresponding wind protection measures need to be taken. Therefore, it is not suitable for high ceilings.

[0004] At present, no effective solution has been proposed for the problems existing in the relevant technology, such as the high cost of steel frame roofs, the sensitivity of tensile membranes to wind loads and their unsuitability for high roof ceilings. Utility Model Content
