In said structure, the bottom of described heat insulation is fixed by reinforced rib.
Wherein, the top of described door-plate, bottom and both sides are provided with fire proof seal plate.Further, the fire proof seal plate bottom described door-plate and door slide block are fixed and embed in sill.Fire proof seal plate and the door volume at described door-plate top form labyrinth seal structure, and the fire proof seal plate of door-plate both sides forms labyrinth seal structure with other overlapping, and the fire proof seal plate bottom door-plate and sill form labyrinth seal structure.
In said structure, the width of described heat insulation is identical with the width of layer door.
Wherein, top and the both sides of described door-plate are U-shaped, and the cross section of described reinforced rib is Z-shaped, and its side is bonding with door-plate, and opposite side is close to outer thermal insulation layer, the upright position of middle linkage section restriction heat insulation, and the end of reinforced rib and door-plate both sides are fixed.
In said structure, fire proof seal plate and the door volume at described door-plate top form labyrinth seal structure, and the fire proof seal plate of door-plate both sides forms labyrinth seal structure with other overlapping, and the fire proof seal plate bottom door-plate and sill form labyrinth seal structure.
In fire-proof and thermal-insulation elevator door of the present utility model, owing to have employed the thermal insulation material that piecemeal is installed, so can not be damaged because of door-plate temperature distortion as monoblock thermal insulation material, and easy for installation, practical reliable.In addition, heat insulation adopts two kinds of different materials to combine, have the feature of low thermal conductivity material intercept heat conduction and the effect of high hardness strength materials fixed pedestal concurrently, effectively can control the thickness of door-plate, for the layer door designing different operating needs is provided convenience.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Fire-proof and thermal-insulation elevator door of the present utility model, as shown in Figure 1 and Figure 2, some heat insulations 4 are provided with in the door-plate 1 of described layer door, described heat insulation 4 is fixed by reinforced rib 5, each heat insulation 4 comprises pressing close to the inner insulating layer 2 of door-plate 1 and the outer thermal insulation layer 3 away from door-plate 1, as shown in Figure 3, the permeability to heat of described inner insulating layer 2 is less than the permeability to heat of outer thermal insulation layer 3, and the intensity of inner insulating layer 2 and hardness are less than intensity and the hardness of outer thermal insulation layer 3, such as inner insulating layer 2 is nano heat-insulating plate, and outer thermal insulation layer 3 is calcium silicate board.
As shown in Figure 2, Figure 4 shows, door-plate 1 is bent by metal sheet and forms, its top and both sides are U-shaped embeds for heat insulation 4.The width of heat insulation 4 is substantially identical with the width of layer door, the cross section of reinforced rib 5 is Z-shaped, its side is bonding with door-plate 1, opposite side is close to outer thermal insulation layer 3, middle linkage section is positioned at the bottom of heat insulation 4 and the upright position of restriction heat insulation 4, the end of reinforced rib 5 and door-plate 1 both sides are fixed by rivet 6 or screw etc., as shown in Figure 3.
The top of door-plate 1, bottom and both sides are provided with fire proof seal plate 7.As shown in Figure 1, fire proof seal plate 7 and the door volume 10 at door-plate 1 top form labyrinth seal structure, as shown in Figure 3, the fire proof seal plate 7 of door-plate 1 both sides overlaps 11 with side and forms labyrinth seal structure, embeds sill 9 and forms labyrinth seal structure with sill 9 after the fire proof seal plate 7 bottom door-plate 1 is fixing with door slide block 8.When fire occurs, door volume 10, other cover 11 and sill 9 are fixing on the wall, obvious distortion can not be there is because of het expansion, and door-plate 1 is only connected with layer door gear on top, by fiery face rapid expanding when fire occurs, and speed of expansion exceedes the fiery face of the back of the body, fiery face of supporting or opposing, four limits of door-plate 1 extends, can cave in by fiery face in the middle part of door-plate 1, now the gap of labyrinth seal structure can diminish until mutually fasten, and effectively can stop the leakage of flame and hot gas like this.
When fire occurs, be comparatively significantly out of shape although door-plate 1 can produce, the thermal insulation material that in the utility model, sectional type is installed can adapt to this distortion automatically, can not produce the phenomenon that thermal insulation material destroys because of door plate deformation, can provide better protection in a fire.
In addition, heat insulation adopts two kinds of different materials to combine, have the feature of low thermal conductivity material intercept heat conduction and the effect of high hardness strength materials fixed pedestal concurrently, effectively can control the thickness of door-plate, for the layer door designing different operating needs is provided convenience.
Be described in detail the utility model by specific embodiment above, above-described embodiment is only preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment.When not departing from the utility model principle, the equivalent replacement that those skilled in the art makes the Material selec-tion of inside and outside thermal insulation layer, the shape of reinforced rib and connection mode etc. and improvement, all should be considered as in the technology category protected at the utility model.
