Embodiment Construction

[0020] Such as figure 1 , 4 As shown, the super fire-resistant door leaf of the present invention includes a front panel 1, a rear panel 2 and a core plate 3 placed between the front panel 1 and the rear panel 2, and the front panel 1 or / and the rear panel 2 are vacuum Airtight cavity.

[0021] At least one panel is a vacuum-tight cavity, which is beneficial to heat insulation and reduces the weight of the panel.

[0022] As an example, the rear panel 2 and the front panel 1 of the vacuum-tight cavity are formed in this way.

[0023] The rear panel 2 includes an outer plate 21, an inner plate 22, a peripheral frame 23 and a plurality of support columns 24 supported between the outer plate 21 and the inner plate 22, the peripheral frame 23 and the outer plate 21 , The inner layer board 22 is airtightly connected and vacuumized.

[0024] The front panel 1 includes an outer plate 11, an inner plate 12, a peripheral frame 13 and a plurality of support columns 14 supported betw...

Abstract

The invention discloses a super-fireproof door leaf, comprising a front panel (1), a rear panel (2) and a core panel (3) arranged between the front panel (1) and the rear panel (2), wherein the front panel (1) or / and the rear panel (2) are vacuum enclosed cavities, and the core panel (3) is composed of a plurality of polygonal frameworks (31) continuously spliced along a plane. The super-fireproof door leaf provided by the invention has light weight, good heat insulation effect and good fireproof performance.

Description

technical field [0001] In the technical field of fire doors of the present invention, in particular, a super fire-resistant fire-proof door leaf whose fire-resistant performance is far better than conventional fire-proof doors. Background technique [0002] Fire doors, also known as smoke-proof doors, including door frames and matching door leaves, are doors used to maintain the fire-resistant integrity of fire escapes and provide escape routes. Its purpose is to ensure that within a reasonable period of time (usually the escape time), people who are escaping in the fire escape are protected from the threat of fire, including blocking smoke and heat. Among them, the heat insulation and fire resistance of the fire door leaf have the most important influence on its overall performance. [0003] Existing fire door leaves are usually as described in the Chinese invention patent application "fire door core and fire door" (application number: 201380034441.7, publication date: 201...
