Embodiment 1

[0032] Embodiment 1, please refer to the attached figure 2 As shown, the technical solution of the present invention provides a high-energy-saving, heat-insulating, sound-insulating and fire-resistant steel door, which includes a door frame 1 and two door panels 2 respectively installed on the front and rear end faces of the door frame 1. The door frame 1 is rectangular The glass fiber reinforced polyurethane frame, the two door panels 2 are galvanized cold-rolled steel plates, and the outer surfaces of the two door panels 2 are painted with fireproof paint, the fireproof paint is mainly made of cement (Portland cement , magnesium oxychloride or inorganic high-temperature binder, etc.), aggregates (expanded vermiculite, expanded perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers, hardeners, waterproofing agents, etc. ) and water, the inside of the door frame 1 is provided with a filling layer 3 between the two door panels 2, the fi...

Embodiment 2

[0033] Embodiment 2, please refer to the attached figure 2As shown, the inner surfaces of the two door panels 2 are all cast-welded with rice-shaped reinforcing ribs 21, and each rib section of the rice-shaped reinforcing ribs 21 is straight-sided arc-shaped. Design, so that the strength of each door panel 2 is improved, and the impact resistance is strengthened. There are several mounting holes 23 through the two door panels 2, and each two is a group, and each group is located one by one in each The ribs are close to both sides of the edge head of the door panel 2, and the outer opening of each of the mounting holes 23 is provided with a nut hidden groove 23a, and each of the two corresponding mounting holes 23 on the two door panels 2 Both are interspersed with hexagonal long screws 24, and two sets of flat pads 24a and sealing rubber rings 24b are respectively sleeved on the rod bodies at both ends of the hexagonal long screw rods 24, and the hexagonal long screw rods 24 ...

Abstract

The invention discloses a high-energy-conservation, heat-insulation, sound-insulation and fireproof steel door which comprises a door leaf framework and two door leaf panels installed on the front endface and the rear end face of the door leaf framework correspondingly. The door leaf framework is a rectangular glass fiber reinforced polyurethane frame body, and a filling layer is arranged at theposition, located between the two door leaf panels, in the door leaf framework. The filling layer comprises a fireproof plate. Honeycomb material layers are connected to the surfaces of the two edges,close to the front door leaf panel and the rear door leaf panel, of the fireproof plate. Each honeycomb material layer is composed of an elastic honeycomb rubber piece and a honeycomb panel wrapped on the outer surface of the elastic honeycomb rubber piece. By means of the high-energy-conservation, heat-insulation, sound-insulation and fireproof steel door, a glass fiber reinforced polyurethane material is used for manufacturing a sectional material to serve as the door leaf framework, the strength of a door leaf can be ensured, meanwhile, the sectional material serves as a broken bridge to be matched with honeycomb materials and a fireproof plate between the back plate and the face plate to achieve a heat-insulation, sound-insulation and fireproof function, and in addition, a high energy-conservation effect can also be achieved by means of the efficient heat insulation effect of the sectional material.

Description

technical field [0001] The invention mainly relates to the technical field of steel doors, in particular to a steel door with high energy saving, heat preservation, sound insulation and fire resistance. Background technique [0002] Most of the existing steel door leaves are formed by cold bending of two steel plates on the back and the face, and the two panel plates are either mechanically snapped together, or welded or riveted. The form of direct connection between two panels has cold bridges and sound transmission media, which cannot meet the higher requirements for heat preservation, sound insulation and fire resistance. Bring effective energy saving effect. Contents of the invention [0003] The present invention mainly provides a steel door with high energy saving, thermal insulation, sound insulation and fire resistance, which is used to solve the technical problems raised in the above-mentioned background technology. [0004] The technical solution adopted by the...
