Description

Technical Field

[0001] The utility model relates to the technical field of building skylights, and in particular to a gravity self-sliding opening skylight structure, a device and a fire protection system. Background Art

[0002] The full-height atrium is a special design form in architecture. Its characteristic is that the atrium space is vertically connected to form a multi-layer or multi-functional shared space. This design form is widely used in commercial buildings, office buildings, hotel buildings and other types of buildings. The full-height atrium can bring natural light into the deep layers of the building, improve the indoor environment, and create a unique visual effect and spatial experience; secondly, the full-height atrium can promote communication and interaction between different floors, and enhance the sociability and publicity of the building.

[0003] According to the Code for Fire Protection Design of Buildings (GB 50016-2014), smoke exhaust facilities should be installed in the atrium. Smoke exhaust facilities can effectively exhaust the smoke in the atrium, keep the sight line in the atrium clear, and facilitate personnel evacuation and fire rescue. Therefore, an openable skylight is usually installed on the roof.

[0004] The existing openable skylights for lighting are mostly pneumatically opened smoke exhaust skylights, but each openable skylight requires a separate drive device, and the large number of drive devices makes subsequent maintenance more troublesome; if a single-layer sliding smoke exhaust skylight is used, when a skylight with a larger opening area is required, the opening part that is translated to the side of the roof has a larger area, which occupies the usable area of ​​the roof, thereby reducing the utilization efficiency of the roof space.

[0005] At present, no effective solution has been proposed for the problems in the relevant technology, such as the large number of pneumatic smoke exhaust skylight drive devices causing trouble for later maintenance, and the large area of ​​the single-layer sliding smoke exhaust skylight reducing the efficiency of roof space utilization.
