Specific embodiment:

Specific embodiment of the present utility model is provided in conjunction with attached drawing, it should be noted that the specific reality of the utility model It is practical new to this to be not construed as convenient for the comprehensive understanding to the technical solution of the utility model for applying the detailed description of mode The limitation of the scope of protection of the claims of type.

The technical solution of referring to Figure 1~Fig. 6, specific embodiment of the utility model are: including doorframe 2 and door leaf 3, door leaf 3 is connect through hinge 4 with doorframe 2, and door leaf 3 is equipped with door lock 1, it is important to and the cladding steel plate of doorframe 2 is equipped with bridge cutoff structure, The bridge cutoff structure has blocked heat to be coated the conduction of steel plate, and the mating surface of door leaf 3 and doorframe 2 is equipped at least two seals item 5, Door leaf 3 is steel wood composite construction, which is to be equipped with high-intensitive layer 7, high-intensitive 7 surface of layer on 6 liang of surfaces of substrate For layer of wood 8,8 surface of layer of wood is decorative layer 9；Above-mentioned door leaf 3 and doorframe 2 is steel wood composite construction, but is had any different, Above-mentioned technical solution ensures that entry door has splendid thermal and insulating performance, while there is more wooden entry door to be greatly improved Security performance.

The cladding steel plate of the doorframe 2 coats steel plate 11 by the first cladding steel plate 10, second, third coats 12 and of steel plate 4th cladding steel plate 13 is constituted, the mating surface of door leaf 3 and doorframe 2 be it is step-like, step-like mating surface causes crack between a door and its frame to be to bend Shape, the resistance for flowing air through crack between a door and its frame are significantly increased, and the step of door leaf 3 and doorframe 2 at least should be two, most preferably three (shown in Fig. 2~Fig. 4) is equipped between the first and third cladding steel plate (10,12) and item 14 is blocked to form sealing structure, at third and fourth Coating to be equipped between steel plate (12,13) blocks item 14 to form second seals structure, and the second cladding steel plate 11 and third coat steel plate There is interval to form bridge cutoff structure without being in contact between 12；The end of above-mentioned blocking item 14 is between doorframe 2 and door leaf 3 Crack between a door and its frame is sealed in crack between a door and its frame, blocks flowing of the air through crack between a door and its frame, is blocked item 14 to be prepared by flexible rubber-plastics material, is made its master Body had not only been not easy to deviate from out of recess portion that formed between cladding steel plate but also had kept end deformable to adapt to crack between a door and its frame width in being used for a long time Variation.

The corner positions for the step-like mating surface that the door leaf 3 is matched with doorframe 2 are equipped with sealing strip 5, sealing strip 5 There is overlapping in part just corresponding or mutual with the blocking end of item 14 above-mentioned, and sealing strip 5 can incite somebody to action after matching with item 14 is blocked The bigger section sealing of crack between a door and its frame, makes air be more difficult to flow by crack between a door and its frame, sealing strip 5 is elastically deformable plastic material system It is standby, the easy adaptive deformation under the extruding of door leaf 3 and doorframe 2 and achieve the effect that better seal crack between a door and its frame.

The substrate 6 of the door leaf 3 be silicate aluminum board or be graphite polystyrene board or be extrusion molding formed plastic plate, substrate 6 be the foundation of door leaf 3, and has preferable intensity and lesser quality, while its thermal conductivity is relatively low, becomes door leaf 3 Layer structure thermal insulation layer；The high-intensitive layer 7 is sheet metal or is steel screen layer or be steel wire that steel wire is worked out With composite steel wire stratum reticulare made of plastic material extrusion molding, high-intensitive layer 7 clamps substrate 6, not only obtains the intensity of door leaf 3 very big Raising, and the non-deformability of globality is also significantly increased, if above-mentioned high-intensitive layer 7 is made of plastic material extrusion molding When composite steel wire stratum reticulare, the substrate 6 that can be formed with extrusion molding is integrally prepared with co-extrusion technology, further reduced preparation cost and letter Preparation process is changed.

The end of the substrate 6 of the door leaf 3 is equipped with wooden end 15, and wooden end 15 is through refractory process, also Effect is for convenient for combining with the installation of sealing strip 5；The part positioned at above-mentioned corner of the sealing strip 5 is that centre has cavity Closed or semienclosed bellows structure, can further improve elasticity or the deflection of sealing strip 5 to improve sealing crack between a door and its frame Effect.

When the door leaf 3 of the entry door is two fan structure, the door lock 1 is between one door leaf 3, two door leafs 3 Mating surface be it is step-like, step corner positions be equipped with sealing strip 5, to block the flowing of air, in the boundary of two door leafs 3 Outer surface at seam is equipped with overlay structure, which is tabular, and one end is fixedly connected with the edge of a door leaf 3, separately The inner surface of one end is equipped with sealing element to seal the gap between 3 surface of door leaf.
