| description | According to the large heat preservation and sound insulation door, two door leaves are installed in a door frame in a matched and hinged mode through door leaf hinges, the protection area of the large heat preservation and sound insulation door can be greatly increased, and the opening and closing rate of the door leaves can be reduced by forming door grooves and passing doors in the side faces of the door leaves. The safety protection and heat preservation effects of the large heat preservation and sound insulation door are improved, the stability of the door leaf can be improved through the supporting framework made of the latticed galvanized sheet, the diameters of the lattices of the supporting framework are gradually reduced from outside to inside, the material loss can be reduced while the stability of the door leaf is guaranteed, and the service life of the door leaf is prolonged. The sound insulation effect of the large heat preservation and sound insulation door can be greatly improved by filling th |
