Background technology

Labeled door most employing fritter door panel assembly unit at present and filling forms, the labeled door core segment exists a large amount of splicing seams and cavity, if take encapsulation process, then cost is high and time-consuming, so labeled door manufacturer generally no longer takes encapsulation process, cause labeled door core heat-proof quality to descend, can't reach due fire-proof function.

The utility model content

Main purpose of the present utility model provides a kind of integral door core labeled door, and it not only has preferable fire prevention usefulness, and product structure is simple, easy to make.

For achieving the above object, the utility model adopts following technical scheme:

A kind of integral door core labeled door includes doorframe and door-plate, and this door-plate is installed on the doorframe, and described door-plate comprises whole expanded perlite door panel or expanded vermiculite door panel, is coated with steel plate in this door panel.

As a kind of preferred version, described steel plate includes the front spring of being close to the door panel leading flank and is close to the back steel plate of door panel trailing flank, laminate side end face after the rim bending of this front spring and back steel plate in door panel, further comprise an outer bound edge element, this outer bound edge element while hard-pressed bale is lived the bending rim of front spring and back steel plate.

As a kind of preferred version, further include bound edge element in, bound edge element is coated on the side end face of door panel in this, is laminated under front spring and back steel plate.

As a kind of preferred version, described interior bound edge element is the frame plate structure to the unidirectional opening of a side.

As a kind of preferred version, the recess of bound edge element in the lateral margin of described door panel is provided with and is used to take in.

As a kind of preferred version, described outer bound edge element is the frame plate structure to the unidirectional opening of a side.

As a kind of preferred version, described doorframe includes records monoblock expanded perlite doorframe central layer or expanded vermiculite doorframe central layer, and this doorframe central layer includes steel plate outward.

After adopting technique scheme, the utility model compared with prior art has tangible advantage and beneficial effect, specifically concludes following points:

1), its insulating portion (door core) is overall structure, seamless, no cavity has guaranteed good fire prevention and effect of heat insulation.

2), easy for installation, reduced the labeled door production process, efficiency of construction improves greatly;

3), since whole door panel intensity good, labeled door needn't weld web frame in addition, has reduced material cost and time cost;

4), guaranteed a door body integral smoothness, improved product quality;

5), Stability Analysis of Structures, use indeformablely, non-warping for a long time, prolonged labeled door application life;

6), adopt whole concavo-convex molding gate central layer, can produce various colored shape moulding labeled doors easily.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:

The specific embodiment:

Please refer to Fig. 1 to shown in Figure 6, the concrete structure that it has demonstrated the preferred embodiment of the utility model includes doorframe 10 and door-plate 20, and this door-plate 20 is installed on the doorframe 10, wherein by hinge or hinge 30:

Described doorframe 10 includes monoblock expanded perlite doorframe central layer or expanded vermiculite doorframe central layer 11, these doorframe central layer 11 outer steel plates 12 that include.

Described door-plate 20 comprises whole expanded perlite door panel or expanded vermiculite door panel 21, is coated with steel plate 22 equally outside this door panel 21.And, this steel plate 22 includes the front spring 221 of being close to door panel 21 leading flanks and the back steel plate 222 of being close to door panel 21 trailing flanks, laminate side end face 211 after the rim bending of this front spring 221 and back steel plate 222 in door panel 21, further comprise bound edge element 224 in an outer bound edge element 233 and, this outer bound edge element 223 and interior bound edge element 224 are all for being made the frame plate structure to the unidirectional opening of a side by steel plate.Lateral margin corresponding to door panel 21 is provided with the recess 212 that is used to take in interior bound edge element 224, should in bound edge element 224 be flush-mounted in the side end face 211 that is coated on door panel 21 in this recess 212, simultaneously in bound edge element 224 laminated in front spring 221 and back steel plate 222 times.Should outer bound edge element 233 simultaneously hard-pressed bale outside the bending rim of front spring 221 and back steel plate 222, with front spring 221 and after steel plate 222 strong bonded.
