Specific embodiment
Embodiment, as shown in Fig. 1, Fig. 4, Fig. 5, Figure 10: embodiment, as shown in Fig. 1, Fig. 4, Fig. 5 and Figure 10: opposite opened
Steel wooden heat-insulating fireproof door, including doorframe 10 and door leaf 20.It is same as common technique, which necessarily has 2 103 Hes of munnion
Left and right ends are separately connected 1 upper ledge 104 of the upper end of 2 munnions 103, perhaps also have lower frame thus the doorframe 10 or
In inverted " u "-shaped or box.Door leaf 20 includes the left side on the munnion in the left side that left side is hinged at the doorframe 10 by hinge for fireproof
Right wing body 204 on the munnion on the right side that fan body 203, right side are hinged at the doorframe 10 by hinge for fireproof.That is, the left fan body
203 is usual in rectangle with the right wing body 204, and in shutdown state, door leaf 20 is stuck in inside the doorframe 10.The left fan body 203
Right side and right wing body 204 left side between be equipped be equipped with Fire-proof lock 40.Door leaf 20 all has fire surface 201 and carries on the back fiery face 202.
In general, fire surface 201 is the one side being located outside under shutdown state, carrying on the back fiery face 202 is to be located at indoor one side.
Further say:
In conjunction with shown in Figure 11, door leaf 20 includes being formed rectangular by 2 connections of cross bar 2011 and 2 piece vertical bar 2012
Frame 21.Frame rod 22 is equipped in frame 21.Grid 23 is formed with after frame rod 22 is criss-cross.That is, frame rod 22
Both ends be connected on the cross bar 2011 or vertical bar 2012 of corresponding frame 21, grid 23 is preferably square.Filling in grid 23
There is anti-fire door core board 24.Meanwhile the front and rear sides of frame rod 22 are symmetrically successively arranged fire-proof plate 251, cold rolling plating from the inside to the outside
Zinc steel plate 252, burning-resistant medium density fibreboard 253, decorative cover 254.Wherein, inward-outward direction from the inside to the outside defines, and refers to
Side close to corresponding door leaf 20 is inside, the side far from corresponding door leaf 20 is outside.And the left fan body 203
Right edge is equipped with interlocks portion 2031 in a vertical left side, and the left side of the right wing body 204 is equipped with to interlock portion in the vertical right side
2041.When door leaf 20 is closed, staggeredly portion 2031 and the right side staggeredly form staggered occlusion in portion 2041 on the left side.For example, working as door leaf
20 close when, left side interlock the front side face contact in the portion 2031 right wing body 204 left edge portions trailing flank, the right side staggeredly portion
The leading flank of the right edge of the 2041 rear side face contact left fan body 203.In such manner, it is possible to form better flameproof effect.Make
For optimization, left side interlock portion 2031 leading flank on contact the right wing body 204 position can be equipped with following fire prevention expand it is close
Strip of paper used for sealing 50, the right side interlock portion 2041 trailing flank on contact the position of the left fan body 203 also and can be equipped with following fire prevention expansions it is close
Strip of paper used for sealing 50.Obviously, fire-proof expansion seal strip 50 herein is in vertically extending.
Optimization:
In conjunction with shown in Fig. 2 and Fig. 3, hinge for fireproof includes the middle part hinge 31 for being set to the middle side edge of corresponding door leaf 20
And it is set to the end hinge 32 of the upper and lower ends of the side of door leaf 20.Preferable mode is used in fixed on door leaf 20
The position of portion's hinge 31 is equipped with the strengthening steel slab 60 of 8-12mm thickness, and middle part hinge 31 can be by being fixed on corresponding reinforcing
It is indirectly fixed on corresponding door leaf 20 after on steel plate 60.In this way, keeping the connection of door leaf 20 and the doorframe 10 more stable
With it is secured.
As shown in connection with fig. 7, the cross bar 2011 of frame 21 and the section of vertical bar 2012 are in " [" shape.Cross bar 2011 and vertical bar
The 2012 2.0mm lvanized cold rolled strips for being all made of steel are prepared.In conjunction with shown in Figure 12, interlock in the left fan body 203 and the left side
The engaging portion in the engaging portion in portion 2031 and the right wing body 204 and right side staggeredly portion 2041, can frame 21 as shown in Figure 12
To be formed.
As shown in connection with fig. 8, edge on 2 vertical bars 2012 of frame 21 and the lateral surface for a cross bar 2011 being located above
Vertical bar 2012 or cross bar 2011 are vertically arranged with fire prevention groove 211.That is, the fire prevention groove 211 being located on cross bar 2011 is a left side
Right trend, the fire prevention groove 211 on vertical bar 2012 are to move towards up and down.The section of fire prevention groove 211 can be in " [" shape.Phase
Answer, in conjunction with shown in Fig. 6 and Figure 10, the doorframe 10 include can be stuck in body part 101 outside door leaf 20 and can and door
The protrusion 102 that the fire surface 201 of fan 20 contacts.Meanwhile on the munnion 103 of the doorframe 10 and the body part 101 of upper ledge 104,
And the munnion 103 of the doorframe 10 and the protrusion 102 of upper ledge 104 are equipped in the one side of the fire surface 201 of door leaf 20
Fire-proof expansion seal strip 50.When shutdown state, the fire-proof expansion seal strip 50 on the munnion 103 of the doorframe 10 can be just
It is stuck in well in corresponding fire prevention groove 211.In this way, having reached better fire-proof and thermal-insulation effect.
As shown in connection with fig. 9, frame rod 22 is prepared using channel steel, and channel steel is preferably 4.0mm channel steel.
Continue to optimize:
Fire-proof plate 251 use 5mm fire-proof plate, cold-rolling galvanization steel plate 252 use 1.0mm cold-rolling galvanization steel plate, it is fire-retardant in it is close
It spends fiberboard 253 and uses 12mm burning-resistant medium density fibreboard, decorative cover 254 is using copper facing or the wooden facing.In this way, ensure compared with
Under the premise of good fire-proof and thermal-insulation effect, the cost of the heat-insulating fireproof door is lower.Meanwhile door can be made to seem more using copper facing
To be luxurious, and the wooden facing can have more moulding, keep door more aesthetically pleasing.
