Door leaf

Abstract

The invention discloses a door leaf. A base plate of the door leaf is a light-weight plate; the outer surface of the light-weight plate is covered with mesh ribs and a reinforcing layer; structural parts are also arranged in the door leaf, and are separately embedded into the edges of the door leaf, and the positions for mounting a lock, a door closer and a door magnet; each section of the structural parts is connected with other opposite or diagonal structural parts through steel wires; screw holes are also formed in the structural parts on which hinges and the door closer are required to be mounted. The door leaf has the advantages of being light in weight and high in strength, preventing water and fire, being small in heat conductivity coefficient, being resistant to deformation and halogenide, being good in sound insulating effect and the like, is difficult to crack, break and deform in using and transporting processes, and cannot be damaged even being kicked by feet; moreover, the production process and sequence are simple; a door panel is not required to be mounted additionally for reinforcing, so that the cost is lower. In a manner of speaking, the door leaf disclosed by the invention is a new generation of green environment-friendly door leaf.

Description

technical field [0001] The invention relates to the technical field of door manufacturing, in particular to a door leaf. Background technique [0002] Existing indoor doors and outdoor door leaf types are distinguished by materials such as wooden doors, steel doors, stainless steel doors, iron doors, etc. The disadvantages are high cost, heavy weight, and no fire prevention. Fire doors made of fire door core panels (such as foam door core panels), the door panels are mostly made of wood or steel plates, and more glue connections, solid filling, and steel nail anchors are required between the door core panels and door panels. In addition, the wooden door panel is not fire-resistant and has low strength, and the steel door panel will be deformed after being burned, making it difficult to effectively block the spread of toxic fumes. Contents of the invention [0003] In order to solve the above-mentioned deficiencies of the existing door leaves, the object of the present inv...

AI Technical Summary

Problems solved by technology

[0002] The existing indoor doors and outdoor door leaf types are divided into wooden doors, steel doors, stainless steel doors, iron doors, etc. according to the materials. The disadvantages are high cost, heavy weight, and no fire protection.

Fire doors made of fire door core panels (such as foam door core panels), the door panels are mostly made of wood or steel plates, and more glue connections, solid filling, and steel nail anchors are required between the door core panels and door panels. In addition, the wooden door panel is not fire-resistant and has low strength, and the steel door panel will be deformed after being burned, making it difficult to effectively block the spread of toxic fumes.
