Steel wood indoor door

Abstract

The invention discloses a steel wood indoor door which comprises a magnetic attraction plate on a wall and a steel plate door body. The magnetic attraction plate is arranged in a room and is in contact with the steel wood indoor door. The steel plate door body is plated with chrome or aluminum, and the surface of the steel plate door body is coated with an inflaming retarding coating and an anti-fingerprint coating. The steel plate door body is internally provided with a sandwich structure with two layers of inflaming retarding boards clamping a layer of grid-shaped steel frame. A first plate body, namely an iron plate, is welded to the side, facing the wall, of the door body. The first plate body is connected with a second plate body through a first hinge, the long edge, not connected with the first hinge, of the second plate body is connected with a third plate body through a second hinge, and magnets are installed on the side, facing the wall, of the second plate body and the side, facing the wall, of the third plate body respectively. According to the steel wood indoor door, due to the fact that the surface is coated with the inflaming retarding coating and the anti-fingerprint coating, meanwhile, the door body is filled with materials, a foldable shoe rack is installed based on the magnetic attraction principle, the high fireproof performance and physical strength are achieved, cleaning is easy, and the space utilization rate is high.

Description

technical field [0001] The invention relates to an interior door, more specifically, the invention relates to a steel-wood interior door for a room. Background technique [0002] The outer layer of the traditional steel-wood interior door is mostly composed of ordinary steel plates, and the inner layer of the door is mostly composite wood boards. Although this kind of steel-wood interior door has certain fire resistance, it is easy to absorb a large amount of heat energy in the event of a fire, causing the door to be damaged. The body temperature rises to ignite the wood inside the door and the combustibles around the door. The overall flame retardant and anti-corrosion performance is poor, and the impact resistance and safety are not good enough. The composite wood board often shrinks and expands due to seasonal changes. Cracking and deformation seriously affect the durability of interior doors. Indoor doors often leave various fingerprints and stains on the surface due to...

The overall flame retardant and anti-corrosion performance is poor, and the impact resistance and safety are not good enough. The composite wood board often shrinks and expands due to seasonal changes. Cracking and deformation seriously affect the durability of interior doors

Indoor doors often leave various fingerprints and stains on the surface due to contact with people or objects, which is not easy to clean, and will affect the appearance of the door body after a long time

In addition, in order to store shoes in daily life, the shoe rack is hung on the door body or fixed with screws. Such a fixed shoe rack has the disadvantages of taking up a large space, affecting the appearance, and being inconvenient to open and close the door.
