Abstract

The invention belongs to the field of doors and windows, and specifically relates to a novel door leaf of a fire-proof door. The novel door leaf is suitable for two-piece fire-proof doors and single-piece fire-proof doors. The novel door leaf comprises a door core plate, a door leaf panel, rivets and insertion bars, wherein the door core plate is wrapped up by the door leaf panel, the door leaf panel is formed by two paint-free steel plate, different in specification, vertically jointed, and the joint portions are fixed through rivets, the bottom portion of the door leaf panel is in a topless U shape, the top portion of the door leaf panel is in a topless T shape, and a lateral bar is arranged on the side surface of the topless T shape. The types of specifications of the door leaf panels are reduced, and a paint-free steel plate is employed. The manufacture process is simplified, the production efficiency is improved, and the economic benefit of a manufacturing company is improved.

Description

technical field [0001] The invention belongs to the field of door and window production, and in particular relates to a fireproof door leaf. Background technique [0002] The fire door is one of the fire-fighting facilities used to block the spread of fire. It is a door that is set on the fire-resistant partition bulkhead and can meet the requirements of the same level of fire separation. For fire doors, this includes the frame and leaf. Among them, the door leaf is the core component, and at the same time the market is mainly dominated by side-opening door leaves. In addition to the requirements for the door core board, the side-opening door leaf also has requirements for the door leaf panel, which not only plays a sealing role on the door core board. [0003] Existing door leaves are made of galvanized steel sheets of different specifications and sizes, and then combined with the door core board, fixedly connected by welding the seams, and finally the surface of the door...
