Flat slab ceiling screen

Abstract

The invention discloses a flat slab ceiling screen. The flat slab ceiling screen comprises a smoke detector (1), a marking controller (2), a control line (3), connecting lines (4), a reserved steel bar (5), a telescoping device (6), a smoke barrier plate (7), a floor slab (8), angle iron (9) and a supporting frame (10). By adopting the above structure, the smoke barrier plate does not affect the space at normal time, and is horizontally fixed below the floor plate, and the smoke barrier plate automatically sags through the smoke detector and the controller when a fire hazard occurs in order to realize smoke baffle, so the floor height is reduced, and energy is saved. The invention also discloses a novel vehicle gateway height limiting rack. The novel vehicle gateway height limiting rack comprises a height limiting rack crossbeam (1), a signboard (2), a solar photovoltaic cell panel (3), a horizon (4), a height limiting rack column (5), a storage battery (6) and a charging controller (7). By adopting the above structure, the solar photovoltaic cell panel converts solar energy into electric energy stored in the storage battery during the day, and powers up the LED lamp of the signboard at night, so the renewable clean energy solar energy is used, and pollution is reduced.

Description

technical field [0001] The invention relates to the field of building smoke prevention and exhaust, in particular to a beamless floor smoke-retaining vertical wall. Background technique [0002] Underground structures and other projects should be divided into smoke-proof zones according to the building area. There should be smoke-proof vertical walls between the smoke-proof zones, and the smoke-proof vertical walls should not be less than 500mm protruding from the ceiling. Where there are beams, they can be replaced by beams. However, some underground structures are not conducive to deep excavation of foundation due to geological reasons. In order to gain storey height, beamless floors are adopted. At this time, the use of fixed smoke-shielding vertical walls will affect the use function. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a beamless floor smoke hanging wall. In order to achie...

AI Technical Summary

Problems solved by technology

Places with beams can be replaced by beams, but some underground structures are not conducive to deep excavation of the foundation due to geological reasons. In order to strive for storey height, beamless floors are used. At this time, the use of fixed smoke-shielding vertical walls will affect the use function.
