Fire-resisting sound-insulating safety door and its production method

Abstract

The invention relates to a fireproof and soundproof safety door and a production method thereof. The fireproof and soundproof safety door of the present invention is mainly composed of a surface layer, a steel frame and a reinforcing rib, and is characterized in that two surface layers are provided on both sides of the steel frame; and several surface layers are arranged between the two surface layers. The reinforcing rib is firmly connected with the surface layer as a whole; several holes or spaces through which foam cement can penetrate are arranged on the reinforcing rib; foaming cement is arranged in the steel frame Cement filling material; and a door handle and door shaft reinforcement on the safety door; and a door lock device. Wherein, the two surface layers are both steel plates; or one steel plate, and the other is glass fiber reinforced plastics, wood boards, plastic plates or cement surface layers. The advantages of the present invention are: it has the properties of fire prevention, heat insulation, gas insulation and water insulation; light weight, heat preservation, durability, sound insulation, crack resistance, impact resistance, good weather resistance; acid and alkali corrosion resistance. The invention also has the advantages of quick and convenient construction and low cost.

Description

technical field [0001] The invention relates to a safety device, in particular to a fireproof and soundproof safety door and its manufacturing method. Background technique [0002] At present, fire safety devices are generally made of steel plates and refractory materials. For example: Fire doors are generally made of steel plates and steel keel frames and glass wool refractory materials. Although this kind of fire doors made of soft composite materials has certain fire resistance and safety performance, its overall impact resistance and The safety is not good enough; at the same time, because it generally uses soft glass wool or rock wool core material, its overall strength is reduced. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages in the background technology and provide a safety door with fire prevention and sound insulation performance and its manufacturing method. [0004] Technical scheme of the present inven...
