Fire resisting shutter of highway tunnel
The invention discloses a fire resisting shutter of a highway tunnel. The fire resisting shutter of the highway tunnel comprises a shutter plate and guide rails, and the shutter plate is located between the guide rails on the two sides and longitudinally slides through the guide rails; the fire resisting shutter of the highway tunnel further comprises wind pressure resisting buffering bodies used for buffering transverse vibration of the shutter plate, and the wind pressure resisting buffering bodies are arranged on the two transverse sides of the shutter plate. According to the fire resisting shutter of the highway tunnel, due to the fact that the wind pressure resisting buffering bodies are additionally arranged, the wind pressure resisting buffering bodies can relieve transversely repeating mechanical vibration of the shutter plate, therefore, the phenomena of shutter plate and guide rail warping and shutter plate disengagement due to the fact that wind pressure difference changes are influenced by reasons such as vehicle piston wind are effectively reduced, the maintenance and replacement cycle of the fire resisting shutter in the tunnel is significantly prolonged, safe operation of the tunnel is guaranteed, and the operation cost of the highway tunnel is lowered. The fire resisting shutter of the highway tunnel is simple in structure, low in cost and capable of being applied to the fire resisting shutters of various structures according to the actual conditions.
