Description

Fire-proof smoke-proof soundproof door

This creation is about a fire-proof, smoke-proof and sound-proof door, which mainly refers to a door that can be fireproof, smoke-proof and soundproof.

In order to improve fire safety, fire doors are currently provided to block the source of heat insulation, and the back temperature of the non-heated surface can be lowered below the set temperature, and it can block the penetration of high-heat smoke to prevent people from inhaling the smoke from harming the human body.

The fire door generally has two opposite door panels. The two door panels are surrounded by a frame. Fireproof materials such as fireproof panels and fireproof cotton are arranged in the two door panels to have fire and heat protection effects. An airtight strip is arranged in the center of the frame to close the fire door. At this time, the airtight strip can have a smoke shielding effect.

However, although the fire door is equipped with fireproof material inside, the external sound source can still be directly transmitted to the inside of the fire door by the fireproof material, resulting in poor sound insulation effect of the fire door. At present, to improve the sound insulation effect of the fire door, the thickness of the fire door can be increased. However, this will cause the fire door to be too heavy, costly, and difficult to install. In addition, the fire door and the outer frame are only tightly sealed by an airtight strip, and its tightness is poor, resulting in poor smoke shielding and sound insulation effects. The airtight strip located in the center will cause the door leaf opening and closing to have greater frictional resistance.

The purpose of this creation is to provide a door that can be fire-proof, smoke-proof and soundproof.

The fireproof door of this creation includes a door leaf, the door leaf includes two door panels, two first fireproof layers, two second fireproof layers, an air layer, and a frame. The two door panels are arranged at a relative interval, and the side facing the center is the inner side; And the two first fireproof layers are respectively attached to the inner side of the two door panels; and the two second fireproof layers are respectively arranged on the inner side of the two first fireproof layers; and the one air layer is arranged between the two second fireproof layers, It has a grid frame and at least one air chamber; and the one frame can cover the two door panels, the two first fireproof layers, the two second fireproof layers, and the periphery of the one air layer.
