Abstract

The invention provides a roof skylight air-tight door for civil air-defense construction. The roof skylight air-tight door comprises an air-tight door and a pressure-bearing door frame, a stabilizingpart is arranged in the air-tight door, a scraping part is arranged above the air-tight door, guide rods are driven to rotate through a turntable, a spike rod can be driven to move outwards, meanwhile, when a hydraulic rod is used for driving a spike part to move outwards, the spike rod and the spike part extend out of the end part of the air-tight door to puncture the sealing film, so that sealing liquid filled in the cavity flows out, and a gap between the air-tight door and the pressure-bearing door frame is filled with the sealing liquid; and when the hydraulic rod transversely moves and moves towards the inner side, a framework vertical beam and a framework cross beam generate certain rotation towards the outer side, an inclined boss is vertical and is tightly attached to the inner wall of the air-tight door, the internal strength of the air-tight door is conveniently improved, the stability of the air-tight door is effectively improved, and the stability of the skylight air-tightdoor can be enhanced while liquid sealing of the gap is achieved.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a roof skylight airtight door used in civil air defense engineering. Background technique [0002] Civil air defense engineering refers to the underground protective buildings built separately to ensure the shelter of personnel and materials in wartime, civil air defense command, and medical rescue, as well as the basement built in combination with ground buildings that can be used for air defense during wartime. Civil air defense engineering is to prevent sudden enemy attacks. It is an important facility to effectively cover personnel and materials and preserve the potential of war; it is an engineering guarantee to persist in urban combat and support the anti-aggression war for a long time until victory. With the need for integrated development of underground space, some existing buildings are in order to obtain natural lighting. Add skylights to the roof ...
