Description

Technical Field

[0001] The present invention belongs to the technical field of interior decoration building materials, and particularly relates to an aluminum-steel inorganic board composite fireproof door frame and an installation method thereof. Background Art

[0002] Currently, the mainstream fireproof doors are usually steel fireproof doors or wooden fireproof doors. The steel fireproof doors and wooden fireproof doors have poor decorative effects and will seriously affect the decorative effect when applied to the field of interior decoration. Although the aluminum alloy fireproof doors have good decorative effects, the melting point of aluminum alloy is low and the fireproof duration is short. Therefore, there is a need in the market for a fireproof door with good decorative effects and a long fireproof duration. For this purpose, the present application submitted a patent application for invention named "A Fireproof Door Frame with a Modern Minimalist Style and an Installation Method" on October 14, 2020. However, the following problems were found during the actual application process: 1. The fireproof expansion strip on the main frame bar is exposed, resulting in poor decorative effect; 2. The fireproof and flame-retardant rubber strip on the stop block has poor adhesiveness and is not easily adhered to the stop block, which causes the exposure of the stop block and poor decorative effect; 3. In practice, the lengthening block of the door pocket is made of inorganic board with a film. The side film is difficult, the adhesive force is poor, and it is extremely easy to fall off. Moreover, the inorganic board has low strength and high brittleness and is extremely easy to be damaged during the installation and use process. Therefore, this technical solution must be improved.
