Sound insulation and dampproof door

Abstract

The invention belongs to the field of doors and windows of fixed constructions, and particularly discloses a sound insulation and dampproof door comprising a door body movably hinged to a door frame. The door body includes an inner plate, a sound insulation layer, a damp removing layer, a water absorption layer and an outer plate in sequence from inside to outside. The inner plate and the outer plate are both formed by splicing a plurality of wooden strips. The sound insulation layer is composed of cotton fibers, wood chips and sound-absorbing cotton. The damp removing layer is composed of crushed wheat straw and a heat transferring wire. The heat transferring wire is attached to the crushed wheat straw. The end of the heat transferring wire communicates with a power source. The water absorption layer is laid outside the damp removing layer and composed of salt and flour. The outer plate is fixed outside the water absorption layer. The part between the inner plate and the outer plate are fixed with screws. The sound insulation effect is good, noise is reduced obviously, and the door body is prevented from being damp effectively.

Description

technical field [0001] The invention belongs to the field of doors and windows of fixed buildings, in particular to a special-purpose door. Background technique [0002] In the building decoration industry, people generally use wooden doors to decorate their rooms. However, the sound insulation and sealing performance can not reach the ideal effect, which seriously affects the acoustic environment of people's private space. In particular, the noise in public places is relatively loud, and soundproof doors are needed to arm the office space. [0003] The Chinese patent document with the publication number CN102561911A discloses a wooden soundproof door, which includes a wooden door frame and a door leaf. The door leaf includes a frame-shaped door stile. Vibration damping plate, sound insulation board and decorative veneer are fixed on the vibration damping plate in turn; the outer side of the door frame is provided with an outer groove matching the door leaf, and the upper ...

AI Technical Summary

Problems solved by technology

The wooden soundproof door improves the sound insulation effect of the door to a certain extent through the cooperation of the inner and outer grooves, but the door body is often deformed in wet weather. At this time, the sealing performance of the inner and outer grooves will be greatly weakened, and the sound insulation effect will be greatly improved. reduce
