[0048] Embodiment

[0049] This embodiment provides an energy-saving steel-wood composite entrance door, as Figures 1 to 3 shown, which includes a door frame, a door leaf, and a hinge 3. The door leaf is arranged inside the door frame, and the hinge 3 is arranged between the door frame and the door leaf.

[0050] Figure 1 is a schematic cross-sectional view of the door body in the horizontal direction, Figure 3 is a schematic cross-sectional view of the door body in the vertical direction. In this embodiment, the door frame includes a separated inner door frame 11 and an outer door frame 12, and the first flame-retardant wood skeleton is respectively connected to the inner door frame 11 and the outer door frame 12. The fireproof and heat-insulating member 5 is arranged inside the door leaf. The door leaf includes a separated door leaf front plate 21 and a door leaf rear plate 22, and the door leaf front plate 21 and the door leaf rear plate 22 are respectively connected to opposite sides of the fireproof and heat-insulating member 5.

[0051] In the above structure, by arranging the first flame-retardant wood skeleton to separate the inner door frame 11 and the outer door frame 12, there is no direct contact between the inner door frame 11 and the outer door frame 12, and by arranging the fireproof and heat-insulating member 5 between the door leaf front plate 21 and the door leaf rear plate 22, there is no direct contact between the door leaf front plate 21 and the door leaf rear plate 22. Therefore, a broken bridge is formed between the inner door frame 11 and the outer door frame 12 and between the door leaf front plate 21 and the door leaf rear plate 22, blocking the transfer and dissipation of heat.

[0052] Specifically, the first flame-retardant wooden skeleton includes a doorframe edge-locking wooden skeleton 41, a doorframe hinge-side wooden skeleton 42, a doorframe upper-side wooden skeleton 43, and a doorframe lower-side wooden skeleton 44. The ends of the four are fixedly connected to each other to form a frame-like structure. Both the inner doorframe 11 and the outer doorframe 12 are frame-like structures. During installation, the inner doorframe 11 and the outer doorframe 12 are respectively arranged on both sides of the first flame-retardant wooden skeleton and fixed to the first flame-retardant wooden skeleton by screws.

[0053] In this embodiment, the energy-saving steel-wood composite entrance door further includes a second flame-retardant wooden skeleton, which is arranged on the periphery of the door leaf and is located between the front door leaf panel 21 and the rear door leaf panel 22.

[0054] In the above structure, the second flame-retardant wooden skeleton includes a door leaf edge-locking wooden skeleton 61, a door leaf hinge-side wooden skeleton 62, a door leaf upper-side wooden skeleton 63, and a door leaf lower-side wooden skeleton 64, and the four are respectively arranged on the corresponding sides of the door leaf. The corresponding sides of the door leaf refer to: the door leaf edge-locking wooden skeleton 61, the door leaf hinge-side wooden skeleton 62, the door leaf upper-side wooden skeleton 63, and the door leaf lower-side wooden skeleton 64 are respectively arranged on the edge-locking side, hinge side, upper side, and lower side of the door leaf. The adjacent ends of the four are fixed, so that the second flame-retardant wooden skeleton forms a frame-like structure sleeved on the periphery of the fireproof and heat-insulating member 5.

[0055] By arranging the second flame-retardant wooden skeleton on the periphery of the fireproof and heat-insulating member 5, and fixing the front door leaf panel 21 and the rear door leaf panel 22 on both sides of the second flame-retardant wooden skeleton respectively, the heat insulation effect between the front door leaf panel 21 and the rear door leaf panel 22 can be improved.

[0056] Figure 2 The following shows a schematic structural diagram of the edge-locking of the door leaf and the doorframe, that is, when the door leaf is closed, it is locked by the fireproof lock body 10 arranged on this side. Correspondingly, the opposite side is the hinge side, and the hinge 3 is connected to this side to realize the rotation of the door leaf relative to the doorframe. Among them, the hinge 3 adopts a fireproof hinge 3.

[0057] As Figure 1 and Figure 3 shown, both ends of the front door leaf panel 21 and the rear door leaf panel 22 are bent, and the bent ends of the front door leaf panel 21 and the rear door leaf panel 22 are attached to and fixed to the corners of the second flame-retardant wooden skeleton.

[0058] In the above structure, both ends of the front door leaf panel 21 and the rear door leaf panel 22 are bent towards the second flame-retardant wooden skeleton, and can be fixed to the second flame-retardant wooden skeleton through this bent part, and specifically, screws can be used for fixation.

[0059] In this embodiment, in order to improve the airtightness, heat insulation performance, and heat preservation performance of the entrance door, a first fireproof seal 7 is filled in the space between the door leaf and the doorframe, and the door leaf and the doorframe are separated by the first fireproof seal 7.

[0060] For example, in Figure 1 as well as Figure 2 In the structure shown, the inner door frame 11 is formed with a stepped side adapted to the bent end of the door leaf rear plate 22, and a fireproof seal is arranged between the stepped side and the bent end. The outer door frame 12 is formed with two stepped sides adapted to the bent end of the door leaf front plate 21, and a first fireproof seal 7 is arranged between any of the stepped sides and the bent end.

[0061] By forming a stepped structure on the inner door frame 11 and the outer door frame 12, when the door leaf is closed, the locking side of the door leaf can abut against the stepped structure, and a first fireproof seal 7 is provided on the stepped structure, which can improve the air tightness, heat insulation and thermal insulation performance of the door frame and door leaf abutment.

[0062] In this embodiment, in order to improve the heat insulation effect between the inner door frame 11 and the outer door frame 12 , a second fireproof sealing member 8 is provided in the interval between the inner door frame 11 and the outer door frame 12 .

[0063] For example Figure 2 In the structure shown, a cavity is provided at the ends of the outer door frame 12 and the inner door frame 11 close to each other, and a second fireproof seal 8 is placed and fixed inside the cavity. The second fireproof seal 8 is respectively abutted against the outer door frame 12 and the inner door frame 11 to improve the heat insulation effect therebetween.

[0064] In this embodiment, if Figure 2 As shown, in order to improve the heat insulation effect between the door front plate 21 and the door rear plate 22, a third fireproof seal is arranged between the ends of the door front plate 21 and the door rear plate 22.

[0065] Specifically, in this embodiment, the first fireproof seal 7, the second fireproof seal 8 and the third fireproof seal 9 can be made of the same material. In this embodiment, the first fireproof seal 7, the second fireproof seal 8 and the third fireproof seal 9 are all fireproof sealing strips.

[0066] The energy-saving steel-wood composite entrance door provided in this embodiment improves the heat insulation effect of the energy-saving steel-wood composite entrance door by setting a first flame-retardant wooden frame to partition the heat transfer between the inner door frame 11 and the outer door frame 12, setting a fireproof heat insulation component 5 and a second flame-retardant wooden frame to partition the heat transfer between the door leaf front plate 21 and the door leaf rear plate 22. At the same time, a first fireproof seal 7 is set between the door leaf and the door frame, a second fireproof seal 8 is set in the interval between the inner door frame 11 and the outer door frame 12, and a third fireproof seal 9 is set between the ends of the door leaf front plate 21 and the door leaf rear plate 22, so as to further improve the air tightness, heat insulation and thermal insulation performance of the energy-saving steel-wood composite entrance door.

[0067] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaustively list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model creation.
