Description
Technical field:
The present invention relates to architecture storey technical field, relate to the fire prevention of skyscraper staircase in particular and grip door.
Background technology:
In skyscraper during breaking out of fire, 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 arranges rolling screen door in staircase, when the intensity of a fire is altered, the intensity of a fire is stoped by drop-down for the rolling screen door of the staircase above it, but the handle portion of rolling screen door is general higher, normally closing the door needs people to hold extension bar to carry out drop-down to the handle portion catching on rolling screen door, so not only inconvenient, and it needs the instrument by other when 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 the fire prevention of a kind of skyscraper staircase to grip door, and its convenient mobile operation, and good airproof performance, can prevent from the staircase intensity of a fire is altered.
Technology solution of the present invention is as follows:
The fire prevention of skyscraper staircase grips door, comprise staircase, midfeather is provided with between the going upstairs and go downstairs of described staircase, stair stringer above going downstairs forms raised item, the sidewall of going downstairs forms oblique fixed lobe bar, the sidewall that midfeather is relative with the sidewall of going downstairs forms and is obliquely pressed against raised item, oblique fixed lobe bar is hinged with upset sliding door by hinge, the hinged side of upset sliding door is pressed against on hinge, opposite side is pressed against and is obliquely pressed against 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 that 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;
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 being pressed against raised item equals the thickness overturning sliding door.
The lower edge of described sliding door is fixed with Handheld Division.
Described sidewall of going downstairs also is fixed with sliding door fixator, and sliding door fixer structure is, one end of connecting rod is fixed on the sidewall of going downstairs, and the sidewall that connecting rod is vertically gone downstairs, the other end of connecting rod is hinged with cursor.
Described main door-plate is identical with sliding door structure to be, and the front-rear side walls 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.
Described oblique fixed lobe bar and oblique top of being pressed against raised item form the lug upwards extended, and the both sides that sliding door shifts out the part of main door-plate are pressed against oblique fixed lobe bar respectively and are obliquely pressed against on the lug of raised item.
Beneficial effect of the present invention is:
Its convenient mobile operation, and good airproof performance, can prevent from the staircase intensity of a fire is altered.

Detailed description of the invention:
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 between 12 and be provided with midfeather 13, the stair stringer of going downstairs above 12 forms raised item 3, go downstairs 12 sidewall on form oblique fixed lobe bar 4, midfeather 13 with go downstairs 12 the relative sidewall of sidewall on form and be obliquely pressed against raised item 5, oblique fixed lobe bar 4 is hinged with upset sliding door 7 by hinge 6, the hinged side of upset sliding door 7 is pressed against on hinge 6, opposite side is pressed against and is obliquely pressed against 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 structure is that 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.
The lower edge of described sliding door 72 is fixed with Handheld Division 721.
Described go downstairs 12 sidewall on be also fixed with sliding door fixator 8, sliding door fixator 8 structure is, one end of connecting rod 81 is fixed on goes downstairs on the sidewall of 12, connecting rod 81 vertically go downstairs 12 sidewall, the other end of connecting rod 81 is hinged with cursor 82.
Described main door-plate 71 is identical with sliding door 72 structure to be, and the front-rear side walls of wooden frame 73 is fixed with panel 74, 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 being pressed against raised item 5 equals the thickness overturning sliding door 7.
Described oblique fixed lobe bar 4 and oblique top of being pressed against raised item 5 form the lug 10 upwards extended, and the both sides that sliding door 72 shifts out the part of main door-plate 71 are pressed against oblique fixed lobe bar 4 respectively and are obliquely pressed against on the lug 10 of raised item 5.
Operation principle: when not using at ordinary times, upset sliding door 7 upwards overturns, make its near go downstairs 12 sidewall, rotate the cursor 82 of sliding door fixator 8, make to overturn sliding door 7 be clamped in go downstairs 12 sidewall and cursor 82 between is formed and fixes.
When the intensity of a fire is altered, cursor 82 upwards rotates by staircase 1, it is made not block upset sliding door 7, then upset sliding door 7 is put down, the hinged side of upset sliding door 7 is made to be pressed against on hinge 6, opposite side is pressed against and is obliquely pressed against on raised item 5, then hold Handheld Division 721 push/pull slot 711 of sliding door 72 along main door-plate 71 both sides is moved up, 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, also there is frictional force between sliding door 72 and raised item 3 simultaneously, can prevent sliding door 72 from gliding), like this by midfeather 13, go downstairs 12 sidewall and upset sliding door 7 rising space of staircase 1 is sealed, prevent the intensity of a fire on alter, its structure is simple, easy to operate.
Meanwhile, when mounted in order to ensure shutoff sealing, add fire-proof sealing material as asbestos layer of cloth main door-plate 71 and sliding door 72 and raised item 3, oblique fixed lobe bar 4, oblique being pressed against on the face that contacts between raised item 5.
