Abstract

The invention discloses a steel sound insulation door. The steel sound insulation door comprises a door frame and a door leaf. The door leaf comprises an inner door plate and an outer door plate and further comprises a frame (8) connecting the inner door plate and the outer door plate. The inner door plate (1), a first fireproof layer (2), a first sound insulation layer (3), a core plate layer (4), a second sound insulation layer (5), a second fireproof layer (6) and an outer door plate (7) are sequentially arranged from inner to outer. The inner door plate (1) and the outer door plate (7) are made of steel plates. By means of the multilayer design, the steel sound insulation door is good in sound insulation effect, the strength and the fireproof effect of the door are improved, and demands of special occasions are completely met.

Description

technical field [0001] The invention relates to the technical field of doors, in particular to a steel soundproof door. Background technique [0002] The rapid development of industry and urbanization has inevitably aggravated the degree of noise pollution. [0003] Noise from various occasions in life is exhausting. The most direct harm of noise to the human body is hearing damage, and then acts on the central nervous system of the brain, causing people to have symptoms of neurasthenia such as headache, brain swelling, tinnitus, insomnia, general fatigue and weakness, and memory loss. Compared with people who work in a high-noise environment for a long time, the incidence of hypertension, arteriosclerosis and coronary heart disease is 2-3 times higher than that in a low-noise environment. Noise is extremely harmful to the fetus. High-decibel noise can damage the auditory organs of the fetus, and it can also cause dysfunction of the endocrine glands of pregnant women, le...
