Abstract
The invention discloses a high-fire-resistance steel fireproof wooden door. The high-fire-resistance steel fireproof wooden door comprises a door frame, a door leaf, a fireproof hinge, a fireproof expansion sealing strip and lockpin devices. The door leaf is of a wooden frame structure and comprises a door core board, base layer boards and outer layer panels, and the base layer boards and the outer layer panels are arranged on the two sides of the door core board from inside to outside. The door frame comprises an outer frame body and an inner core. The fireproof expansion sealing strip is embedded in the contact face of the door frame and the door leaf. The two or more lockpin devices are arranged between the upper edge of the door frame and the door leaf in a spaced mode. Each lockpin device comprises a plug bush, a fixing sleeve, a bolt, a compression spring, a fuse link, an end cover and a fireproof expansion rubber gasket. The further improvements are that holes used for fixedly connecting the fireproof expansion rubber gaskets in the plug bushes are blind holes, the section of the fireproof expansion sealing strip is in an L shape, a prying-resistant steel plate is arranged between the base layer board and the outer layer panel located on the counter-fire side, and the door core board is a multi-layer keel frame made from a fireproof board material. The door is high in reliability, and a door plank is not deformed during fires.
Description
Technical field
The present invention relates to a kind of building material field, and in particular to a kind of steel fire-proof wooden door.
Background technology
There is one kind to be wooden door leaf, wooden one fire-resistant door core in existing steel fire-proof wooden door, steel doorframe.This steel wood
When there is fire, door-plate is burnt and can be deformed after certain hour matter fire resistant doorsets（Because flame is altered upwards, deformation position
The general edge on door-plate）, flame, dense smoke will alter crack between a door and its frame, it is difficult to intercept spreading for fire.For this problem, present city
There is a kind of steel fire-proof wooden door one latch gear of arranged for interval between, door leaf on the doorframe on, be provided with latch gear
Latch structure and fuse link, when a fire, fuse link fusing, under spring force effect, latch ladder shaft end can be inserted into
In fire prevention expansion cushion rubber endoporus, so, in the presence of detent configuration, along being connected with door leaf on doorframe, by latch
Form drag of preapring for an unfavorable turn of events can effectively prevent door leaf from deforming, it is to avoid flame, dense smoke altered crack between a door and its frame.But the defect of this structure is：Only set
A latch gear is put, reliability is not high, when a fire just in case this latch gear breaks down, just not having to have
Effect prevents flame and dense smoke from altering the effect of crack between a door and its frame.
The content of the invention
The present invention is directed to the deficiencies in the prior art, proposes that a kind of high fire-retardance steel that can be significantly improved using reliability is wooden anti-
Vent.
The present invention is achieved through the following technical solutions technical goal.

Latch is arranged in fixed cover, is coordinated with fixed cover endoporus gap, and latch is provided with ladder shaft end, the ladder towards sleeve one end
Shaft end can be inserted in fire prevention expansion cushion rubber endoporus；The end cap is fixedly connected on one end of fixed cover dorsad sleeve；The latch,
Fuse link, compression spring are provided between end cap；The fuse link two ends are connected respectively with latch, end cap；The compression spring set
It is mounted on fuse link；It is theed improvement is that：Arranged for interval two or more latch gear between edge, door leaf on the doorframe.
In said structure, the hole for being used to be fixedly connected fire prevention expansion cushion rubber on the sleeve is blind hole.
In said structure, the fire-proof expansion seal strip section is L-shaped, can simultaneously with door leaf side, counter-fire side it is outer
Deck panels are contacted.
In said structure, between basal plate, the outer layer panel of the counter-fire side pick-proof steel plate is provided with.
In said structure, the door panel is the multilamellar keel shoe of PLASTIC LAMINATED material.
The present invention compared with prior art, has the positive effect that：
1. on doorframe between, door leaf arranged for interval two or more latch gear, by multiple latch gears, significantly improve and use
Reliability.
2. the hole for being used to be fixedly connected fire prevention expansion cushion rubber on sleeve is blind hole, when preventing fire, latch multidiameter
In end insertion sleeve during fire prevention expansion cushion rubber, go out from sleeve together with fire prevention expansion cushion rubber, further improve and use reliability.
3. latch gear is provided with end cap in one end of fixed cover dorsad sleeve, need to such as change fuse link, it is only necessary to pull down end
Lid, it is convenient and swift.
4. fire prevention expansion cushion rubber is provided with latch gear sleeve, when there is fire, fuse link fusing, latch ladder shaft end is inserted
Enter in sleeve in fire prevention expansion cushion rubber, fire prevention expansion cushion rubber gradually expands, stuck fast latch ladder shaft end, it is to avoid spring force
Latch ladder shaft end skids off from sleeve when not enough.
5. fire-proof expansion seal strip section is L-shaped, can simultaneously with door leaf side, the outer layer plate contact of counter-fire side, one
Aspect significantly improves door leaf, the sealing of doorframe junction, on the other hand, substantially reduces the strike note of generation of closing the door.
6. pick-proof steel plate is provided between the basal plate of counter-fire side, outer layer panel, on the one hand increases structural strength, the opposing party
Face can play good anti-theft function.
7. door panel is the multilamellar keel shoe of PLASTIC LAMINATED material, and structural strength is high, can play preferable heat-insulation and heat-preservation
Effect.
