Description
Technical field
This utility model relates to a kind of building material field, is specifically related to a kind of steel fire-proof wooden door.
Background technology
Having one in existing steel fire-proof wooden door is wooden door leaf, wooden one anti-fire door core board, and steel doorframe, anti-fire door core board is generally perlite fireproof plate.Owing to the heat-insulating, fire-preventing performance of perlite fireproof plate is general, therefore, the heat-insulating, fire-preventing performance of existing steel fire-proof wooden door has much room for improvement.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is proposed to a kind of high fire-retardance steel fire-proof wooden door that can significantly improve heat-insulating, fire-preventing performance.
This utility model is achieved through the following technical solutions technical goal.
High fire-retardance steel fire-proof wooden door, including doorframe, door leaf, hinge for fireproof, fire-proof expansion seal strip；Described door leaf side is hinged by hinge for fireproof and doorframe；Described door leaf is wood frame structure, including door panel be arranged on door panel both sides basal plate from inside to outside, outer layer panel；Described doorframe includes housing, inner core, and described housing is the cross section that galvanized steel plain sheet is made is stair-stepping framing component；The contact surface of described doorframe and door leaf side is embedded with fire-proof expansion seal strip；It thes improvement is that: be provided with complex reflex heat-insulating shield between the basal plate of described door leaf counter-fire side, outer layer panel.
In said structure, described complex reflex heat-insulating shield is inorganic SiO2As interval insulant, aluminium foil as the multi-layer compound structure of sandwich material.
In said structure, described doorframe and door leaf side, counter-fire side the contact surface of outer layer panel be embedded with the fire-proof expansion seal strip that cross section is L-shaped；Described fire-proof expansion seal strip can simultaneously with the outer layer plate contact of door leaf side, counter-fire side.
In said structure, described door panel is the multilamellar keel shoe of PLASTIC LAMINATED material.
This utility model compared with prior art, has the positive effect that:
1. the basal plate of door leaf counter-fire side, be provided with complex reflex heat-insulating shield between outer layer panel, on the one hand owing to complex reflex heat-insulating shield has stronger reflection, on the other hand owing to complex reflex heat-insulating shield heat conductivity is extremely low, therefore, heat-blocking action can be played, improve heat-insulating, fire-preventing effect of the present utility model.
2. doorframe is embedded with, with the contact surface of door leaf side, the outer layer panel of counter-fire side, the fire-proof expansion seal strip that cross section is L-shaped, fire-proof expansion seal strip can simultaneously with the outer layer plate contact of door leaf side, counter-fire side, significantly improve the sealing of door leaf, doorframe junction on the one hand, on the other hand, the strike note produced of closing the door is substantially reduced.
3. door panel is the multilamellar keel shoe of PLASTIC LAMINATED material, and structural strength is high, it is possible to play good heat insulation and preservation effect.

Fig. 1 is this utility model structural representation.
Fig. 2 is the A-A profile in Fig. 1.
Fig. 3 is II enlarged schematic partial view in Fig. 2.
Detailed description of the invention
Below according to accompanying drawing and the utility model is described in further detail in conjunction with the embodiments.
The fire-proof wooden door of high fire-retardance steel shown in accompanying drawing, including doorframe 1, door leaf 2, hinge for fireproof 6, fire-proof expansion seal strip 7；Door leaf 2 side is hinged by hinge for fireproof 6 and doorframe 1；Door leaf 2 is wood frame structure, and including door panel 2.1 be arranged on door panel 2.1 both sides basal plate 2.2 from inside to outside, outer layer panel 2.3, door panel 2.1 is the multilamellar keel shoe of PLASTIC LAMINATED material；Doorframe 1 includes housing 1.1, inner core 1.2, and housing 1.1 is stair-stepping framing component for the cross section that galvanized steel plain sheet is made.
The contact surface of doorframe 1 and door leaf 2 side, the outer layer panel 2.3 of counter-fire side is embedded with the fire-proof expansion seal strip 7 that cross section is L-shaped；Fire-proof expansion seal strip 7 can contact with the outer layer panel 2.3 of door leaf 2 side, counter-fire side simultaneously.
Being provided with complex reflex heat-insulating shield 2.4 between the basal plate 2.2 of door leaf 2 counter-fire side, outer layer panel 2.3, complex reflex heat-insulating shield 2.4 is inorganic SiO2As interval insulant, aluminium foil as the multi-layer compound structure of sandwich material.
