Abstract
The utility model discloses a two-side fire prevention and two-side winding steel winding door comprising a door sash, a guide rail and a rotary device. The door sash is made into the bilateral structure and the same page sheet with the method of forming in one piece and is connected by a clasp. The bottom page sheet of the door sash is provided with a touchdown sheet. The door is designed with the Y type guide rail to increase the fire prevention effect and to avoid the occurrence of the contingency. The utility model has the advantages of good fire prevention effect, shapely ornamentation, convenient production process and fixation usage, and good safety. The utility model can be used as a fire prevention, antitheft and decoration steel winding door for the various civil buildings, the important material storehouses, the hotels, and the high-rise buildings.
Description
The utility model relates to the building fireproof steel rolling door.Be applicable to general civil building, usurp rolling door as preventing fires, preventing, also can satisfy the fire safety needs of valuable cargo warehouse, hotel and high-rise building as buildings such as shop, the shop front, garages.
In the prior art, fireproof steel rolling door mostly is single face fire prevention and single face receipts rolling door greatly.Fireproof steel rolling door (the number of patent application: 88212867.1 produced of Daxian county, Sichuan Province machine making factory for example, notification number: CN2031436U), it is made up of door sheet, door sheet lift rotating device, guide rail and ground guide rail, inside and outside door sheet is connected by spot welding, design and installation has fire-proof heat-insulating material between inside and outside door sheet, connect with occlusion structure between the page or leaf sheet of door sheet, there is the height of a baffle plate with the rolling of control door curtain the upper end of door sheet.It is to be solved that this fireproof steel rolling door also exists following problem to have:
1, adopt the single face fire-proof door leaf, towards within doors, not only flameproof effect is restricted, and does not reach the purpose of attractive, decorative shop front decorative layer.
2, door sheet lower end is provided with bottom girder and ground guide rail.When steel rolling-up door is installed, need the ground guide rail is installed on the ground, destroy ground and influence original building; When breaking out of fire, because a recoil strength and an elastic force effect that the door sheet descends, make door be not closed completely close and produce the string fire, leak the cigarette phenomenon, involve neighbour.
3, a door sheet is made by spot welding, and the upper end is provided with baffle plate, and is out of control in case run into that tumbler breaks down when the rolling of curtain door, a sheet rolled up to baffle plate pulled, and not only damages rolling door, and a door sheet falls down from eminence and injures people or thing.The door sheet of spot welding has the phenomenon of taking off a little.
The purpose of this utility model provides a kind of fire prevention, fire-resistant effective, beautiful decoration, and all very easy two-sided fire prevention and the steel rolling-up door of two-way rolling are produced and installed to rolling freely, reliably.
The utility model is achieved in that this steel rolling-up door is made up of the guide rail and the door sheet lift rotating device of the bilateral structure door sheet identical with shape, band Y type.The page or leaf sheet of door sheet is with steel disc or stainless steel substrates, through one-shot forming is the two-sided structure page or leaf sheet identical with shape, between the internal layer of page or leaf sheet, fill fire-proof heat-insulating material 11, with the fire safety that satisfies valuable cargo warehouse, hotel and high-rise building and the needs of attractive, decorative.Be connected to become a sheet by fastener between page or leaf sheet and the page or leaf sheet, the bottom page or leaf sheet of door sheet is equipped with the sheet that contacts to earth.When tumbler when rotating forward or backwards, drive the door sheet along being installed on the tumbler rolling forward or backwards of Y type guide rail or closing.
Reaching in the page or leaf sheet of the utility model door sheet also can be without fire proofing material on the internal layer, adopt aluminium flake to make to decorate usefulness the one side of door sheet, another side is selected steel disc or stainless steel substrates mineral wool for use, is prevented usurping, also can make by two-sided employing commaterial, be used for fire prevention, antitheft and decorating roller blind door as general civil building (as shop, the shop front etc.).
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 (a) is a front view of the present utility model, (b) is the utility model lateral view
Fig. 2 is the page or leaf chip architecture schematic diagram of the utility model door sheet
Among Fig. 1,1, fixed support, 2, rotating shaft, 3, the hole height, 4, transmission device, 5, motor, 6, Y type guide rail, 7, the door sheet, 8, guide rail, 9, page sheet that contacts to earth, 10, the Horizon absolute altitude; Among Fig. 2, (a) the page or leaf sheet schematic diagram that connects for fastener, (b) for having the page or leaf sheet schematic diagram of the sheet that contacts to earth, 11, the heat-barrier material in the page or leaf sheet, 12, the sheet refractory material contacts to earth.
As shown in Figure 1, by motor and drive transmission 4 and rotating shaft 2 rotations, drive a door sheet 7 again and move and rolling along guide rail 8 together with the sheet 9 that contacts to earth, when moving to Y type guide rail 6 places, a door sheet is rolled onto high 3 places of door opening and gets final product.When rolling door is in when closing, the sheet 9 that contacts to earth contacts with ground line 10, because the sheet that contacts to earth is bonding as refractory material 12 with compound glass fiber and fireproof paint, has the characteristics of elasticity and soft or hard appropriateness, so that door curtain is closed and tightly and not gone here and there fire, cigarette thoroughly; Simultaneously, do not need to install the ground guide rail on the ground yet, do not destroy ground and damage original building.
If run into tumbler when out of control, a door sheet continues rolling in rotational direction, when surpassing tumbler 180 and spend, the door sheet will be automatically along on Y type guide rail, closing downwards, rolling so repeatedly always and closing, unlikely damage door curtain with injure people or thing.
Change the rotation direction of motor 5, the door sheet is incited somebody to action rolling in the other direction or is closed.
The utility model compared with prior art has the following advantages:
1, adopt double-side fireproof and two-way receipts rolling door flat, fire-proof and thermal-insulation is effective, and beautiful decoration and rolling are freely.
2, adopt one-shot forming technique to make door sheet hinge, use the fastener connected mode between hinge, make its production technology simple, the door sheet is not fragile.
3, the bottom hinge of door sheet is provided with the sheet that contacts to earth, and does not need to install the ground guide rail, not only closes Tightly, and easy for installation.
4, adopt Y type guide rail, baffle plate is not installed, can avoid the damage door sheet that causes because of tumbler is out of control, injure contingencies such as people or thing, safe in utilization, reliable.
Claims (2)
1, a kind of fireproof steel rolling door of forming by door sheet 7, guide rail 6,9 and tumbler 2,4,5, the page or leaf sheet 7 that it is characterized in that a sheet is with steel disc or stainless steel substrates, through one-shot forming is the two-sided structure page or leaf sheet identical with shape, between page or leaf sheet and page or leaf sheet, be connected to become a sheet by fastener, the bottom page or leaf sheet of door sheet is equipped with the sheet 9 that contacts to earth, when rotate forward or backwards on the tumbler edge, drive the door sheet along being placed in Y type guide rail 6 rollings forward or backwards on the tumbler or closing.
2, according to the said fireproof steel rolling door of claim 1, the bottom page or leaf sheet that it is characterized in that a sheet adopts the contact to earth refractory material 12 of sheet of compound glass fiber and the bonding conduct of fireproof paint.
