Background technology:
When the interior breaking out of fire of skyscraper, the flame of staircase can on alter and spread, increase the weight of the extent of injury of fire, in order to prevent the generation of this thing, existing stop mode is that rolling screen door is set in staircase, in the time altering in the intensity of a fire, by the drop-down intensity of a fire that stops of rolling screen door of the staircase of its top, but the handle portion of rolling screen door is generally higher, normally closing the door needs people to hold the handle portion that extension bar catches on rolling screen door to carry out drop-down, so not only inconvenient, and it need to be by other instrument while pulling, when the Emergency time at fire spreading, once can not find instrument, cannot close the door, just do not stop in the intensity of a fire and alter.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides a kind of skyscraper staircase fire prevention to grip door, and it facilitates move operation, and good airproof performance, can prevent from altering in the staircase intensity of a fire.
Technology solution of the present invention is as follows:
The fire prevention of skyscraper staircase grips door, comprise staircase, between the going upstairs and go downstairs of described staircase, be provided with midfeather, stair stringer above going downstairs forms raised item, on the sidewall of going downstairs, form oblique fixed lobe bar, on a midfeather sidewall relative with the sidewall of going downstairs, form the oblique raised item that presses, on oblique fixed lobe bar, be hinged with upset sliding door by hinge, a hinged side pressure of upset sliding door leans against on hinge, opposite side is pressed against oblique pressing on raised item, and the top of the sliding door of upset sliding door is pressed against on raised item.
Described upset door moving structure is, the both sides of main door-plate are fixed with push/pull slot, and sliding door is above main door-plate, and the both sides sleeve of sliding door is in the push/pull slot of main door-plate both sides.
In the following portion of described sliding door, be fixed with Handheld Division.
On described sidewall of going downstairs, be also fixed with sliding door fixator, sliding door fixer structure is, one end of connecting rod is fixed on the sidewall of going downstairs, the sidewall that connecting rod is vertically gone downstairs, and the other end of connecting rod is hinged with cursor.
Described main door-plate is identical with sliding door structure to be, and on the front and back sidewall of wooden frame, is fixed with panel, is filled with perlite and fills out core between panel and wooden frame.
Described panel is asbestos panel.
The horizontal width of described oblique fixed lobe bar is equal to or greater than the thickness of the upset sliding door of twice.
The described oblique horizontal width that presses raised item equal the to overturn thickness of sliding door.
Described oblique fixed lobe bar and oblique top of pressing raised item form upwardly extending lug, and the both sides that sliding door shifts out the part of main door-plate are pressed against respectively on oblique fixed lobe bar and the oblique lug that presses raised item.
Beneficial effect of the present invention is:
It facilitates move operation, and good airproof performance, can prevent from altering in the staircase intensity of a fire.

The specific embodiment:
Embodiment: see shown in Fig. 1 to 6, the fire prevention of skyscraper staircase grips door, comprise staircase 1, described staircase 1 go upstairs 11 and go downstairs and between 12, be provided with midfeather 13, the stair stringer of 12 tops of going downstairs forms raised item 3, go downstairs on 12 sidewall and form oblique fixed lobe bar 4, on midfeather 13 sidewall relative with 12 the sidewall of going downstairs, form the oblique raised item 5 that presses, on oblique fixed lobe bar 4, be hinged with upset sliding door 7 by hinge 6, a hinged side pressure of upset sliding door 7 leans against on hinge 6, opposite side is pressed against oblique pressing on raised item 5, the top of the sliding door 72 of upset sliding door 7 is pressed against on raised item 3.
Described upset sliding door 7 structures are, the both sides of main door-plate 71 are fixed with push/pull slot 711, and sliding door 72 is above main door-plate 71, and the both sides sleeve of sliding door 72 is in the push/pull slot 711 of main door-plate 71 both sides.
In the following portion of described sliding door 72, be fixed with Handheld Division 721.
On described 12 the sidewall of going downstairs, be also fixed with sliding door fixator 8, sliding door fixator 8 structures are, one end of connecting rod 81 is fixed on 12 the sidewall of going downstairs, vertically go downstairs 12 sidewall of connecting rod 81, and the other end of connecting rod 81 is hinged with cursor 82.
Described main door-plate 71 and identical being of sliding door 72 structures, be fixed with panel 74 on the front and back sidewall of wooden frame 73, is filled with perlite and fills out core 75 between panel 74 and wooden frame 73.
Described panel 74 is asbestos panel.
The horizontal width of described oblique fixed lobe bar 4 is equal to or greater than the thickness of the upset sliding door 7 of twice.The horizontal width of oblique fixed lobe bar 4 equals push/pull slot 711 width and folding hinge width sum.
The described oblique horizontal width that presses raised item 5 equal the to overturn thickness of sliding door 7.
Described oblique fixed lobe bar 4 and oblique top of pressing raised item 5 form upwardly extending lug 10, and the both sides that sliding door 72 shifts out the part of main door-plate 71 are pressed against respectively on oblique fixed lobe bar 4 and the oblique lug 10 that presses raised item 5.
Operation principle: while use at ordinary times, upset sliding door 7 upwards overturn, makes it near going downstairs 12 sidewall, rotates the cursor 82 of sliding door fixator 8, and the sliding door 7 that makes to overturn is clamped in formation between go downstairs 12 sidewall and cursor 82 and fixes.
In the time altering in the intensity of a fire, on staircase 1, cursor 82 is upwards rotated, make it not block upset sliding door 7, then put down upset sliding door 7, the hinged side pressure of the sliding door 7 that makes to overturn leans against on hinge 6, opposite side is pressed against oblique pressing on raised item 5, then holding Handheld Division 721 moves up sliding door 72 along the push/pull slot 711 of main door-plate 71 both sides, be pushed on raised item 3 always, the top of sliding door 72 is pressed against on raised item 3 (owing to having certain frictional force between sliding door 72 and main door-plate 71, between sliding door 72 and raised item 3, also there is frictional force simultaneously, can prevent that sliding door 72 from gliding), like this by midfeather 13, 12 sidewall and the sliding door 7 of overturning of going downstairs seals the rising space of staircase 1, prevented the intensity of a fire on alter, it is simple in structure, easy to operate.
Meanwhile, when mounted in order to guarantee shutoff sealing, add fire-proof sealing material as asbestos layer of cloth at main door-plate 71 and sliding door 72 and raised item 3, oblique fixed lobe bar 4, oblique pressing on the face contacting between raised item 5.
