Problems solved by technology

At present, the sound insulation effect is generally not considered in the design of fire doors. Facing the ubiquitous road traffic noise in life and industrial noise during factory operations, they all cause serious harm to the human body. Living in the noise for a long time will affect people's health. Nervous system, making people irritable and irritable, affecting sleep, causing fatigue, and increasing the incidence of high blood pressure

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0023] Example. A manufacturing method of a steel soundproof and fireproof door of the present invention is as follows: the door leaf of the method adopts a cavity structure of a steel frame covered with a steel plate, and the steel frame is welded with channel steel, angle steel and flat steel; the covered steel plate is Cold-rolled steel sheets with a thickness of 1.2 mm or more. The cavity is filled with sound-insulating materials and fire-proof materials; the sound-insulating material is a high-damping sound-insulating felt pasted on the inner surface of the covering steel plate; the characteristics of high internal damping and good flexibility are used to block the propagation paths of sounds in different frequency bands and suppress the generation of resonance . The fireproof mate...

Abstract

The invention discloses a manufacturing method and structure of a steel soundproof and fireproof door. The door leaf of the method adopts a cavity structure in which a steel frame is covered with a steel plate, and the cavity is filled with sound insulation materials and fireproof materials; The fireproof expansion sealing strip is pasted on the top, and the gap between the door leaf and the door post is sealed by using the characteristic that the fireproof expansion sealing strip will automatically expand in case of fire; the two sides and the upper side of the door leaf are connected with the door frame in a circular arc wave shape Sealing strips for a better fit of the sealing strips. this invention While meeting the fire protection requirements, the sound insulation function is increased. It can meet the needs of fire protection and sound insulation.

Description

technical field [0001] The invention relates to a manufacturing method and structure of a steel soundproof and fireproof door, belonging to the technical field of soundproof and fireproof doors. Background technique [0002] Building standards stipulate that when a door is connected to the front room in a residential building, it must be a fire door. In an industrial building, the door opened on the partition wall that requires a fire compartment must be a fire door. At present, the sound insulation effect is generally not considered in the design of fire doors. Facing the ubiquitous road traffic noise in life and industrial noise during factory operations, they all cause serious harm to the human body. Living in the noise for a long time will affect people's health. The nervous system makes people irritable and irritable, affects sleep, causes fatigue, and increases the incidence of high blood pressure. These noises can be divided into low frequency, medium and low frequen...
