Abstract
The utility model relates to a high-strength double-side rolling corrosion resistant type fireproof rolling gate. The utility model is characterized in that after battens (can also be called curtain boards) being shaped, one end of the utililty model is cylinder-shaped, the other end is arc groove and middle part is straight, realizing the column connection of the battens and the symmetric structure of both sides realizes double-side rolling up; the utility model has same decorated surface of both sides; moreover, connection position has high air tightness and the scuff of the utility model is small; interior is filled with novel expanded fireproof heat-insulating material which can isolate air and reinforce the performance of corrosion preventive. The utility model is especially suitable for guesthouses, high-grade hotels, markets, shopping centers and other projects which have higher requirement of decoration.
Description
The utility model relates to a kind of roller shutter type fire damper.
At present, the fire prevention volume lock that China adopts (or claims rolling door, contain imported product) individual layer coil of strip lock and compound steel fire prevention volume lock (as No. 87208694, Chinese patent, No. 88212057) two classes are arranged, wherein use wide (seeing Fig. 3, Fig. 4) with compound volume lock.But have compound volume lock now owing to structurally with on the technology have some problems, thereby had a strong impact on the functional performance of fire prevention volume lock.Its defective mainly contains:
1, battened construction (referring to the cross section) is that reverse latch closure of both-end or lath connect, belong to the latch closure mode of connection, so can only roll by single face, and the latch closure position exists poor air-tightness and problems such as serious wear and snap-in strength deficiency, so easily thread off, this has influenced reliability of products, compliance and to a great extent in application in engineering.
2, lath (or claim curtain plate) be by two steel bands through the inner chamber that welding or welding roll extrusion form, irritate the fire-proof heat-insulating filler then and form, be subjected to the restriction of structure and technology characteristics and process conditions, its inner chamber can't be filled full fire-proof heat-insulating filler.Thereby the inner chamber long term exposure is in air, so can not prevent the corrosion of surface of internal cavity effectively.From the practical engineering application situation, great majority fire prevention volume lock appearance still can prevent corrosion through surfacing, but the inner chamber corrosion is very serious, makes many volume locks occur corroding hole in use for some time, weakens so that lose fire prevention mitigation function.
3, existing compound volume lock is because its lath backside surface out-of-flatness is very not attractive in appearance.Be applied in the whole weak effect of decorating in emporium, luxurious hotel, restaurant and other the ornamental engineering of having relatively high expectations.
The purpose of this utility model is exactly to be to solve problem and the defective that above-mentioned roller shutter type fire prevention volume lock exists, provide a kind of can two-sidedly roll, wear and tear little, snap-in intensity is good, rational in infrastructure, the novel fire prevention volume of corrosion-resistant lock.
The purpose of this utility model is achieved in that
1, designed novel lath (as shown in Figure 1) structure.This lath is two-sided straight, and an end is a cylinder, and the other end is the arc groove.The cylindrical end radius size is less, and the gap between it and arc groove is between 0.5-0.9mm.During connection the cylinder of a slice lath is inserted in the arc groove of another sheet lath and gets final product.Cylinder can rotate in arc groove, and rotating radian can be by the control of arc groove radian size, to satisfy the scrolling requirement.Generally between 30 °-60 °, it is decided by actual requirement of engineering in rotation radian measure alpha/2.Fire prevention volume lock can solve in the past spool body owing to be subjected to install restriction like this because symmetrical configuration before and after the lath can two-sidedly be rolled, the volume lock can only the lath back side in some engineering outwardly, influence problem attractive in appearance.The routing motion situation of its bond sites also is able to very big improvement, and wearing and tearing greatly reduce, and its intensity and tightness improve greatly.Be straight symmetrical plane because of the two sides simultaneously, its ornamental also improvement greatly.
2, adopt the novel expansile fireproof heat insulating material that has, (forming) cavity filling by alumina silicate fibre band spraying amino fire-proof dilatation, the control loading can make whole lath inner chamber density be full of after expanding, make surface of internal cavity be covered and not contact with air by fire proofing material, thereby improve its anticorrosive property greatly, prolong the application life of fire prevention volume lock effectively, improved the reliability and the economy of fire prevention volume lock.
For realizing process equipment that above-mentioned new technology needs and uncomplicated, mode moulding such as roll extrusion or extruding are adopted in lath processing earlier, fill fireproof heat insulating material then, synthetic in flat segments welding back at last, but lath also can become two symmetrical components at arc groove and cylinder axle center symmetrical center line A-A punishment type, after filling fireproof heat insulating material, synthetic in circular arc and welding back, cylinder place.Laths of metal (1) adopts medium carbon steel or Stainless Steel and the aluminum alloy plate materials of thickness δ=0.8-1.2mm, the thick t=15-20mm of curtain sheet, and high H is decided by actual requirement of engineering, generally at 70-140mm
Description of drawings:
Fig. 1 is a lath profile of the present utility model.(1) among Fig. 1 is a lath, and (2) are the fire-proof heat-insulating filler.
Fig. 2 is fire prevention volume lock schematic diagram.(1) is transmission mechanism among the figure, and (2) are protecting cover, and (3) are range controlling mechanism, and (4) are spool body, and (5) are electric control box, and (6) are lath, and (7) are guide rail.
Fig. 3, Fig. 4 are the lath profiles of patent 87208694.(1), (2) are respectively main and auxiliary batten among the figure, and (3) are spacers.
Embodiment:
Fig. 1 is one of the utility model embodiment.The thick t=18mm of curtain sheet, high H=103mm, arc groove R=6.5mm, cylinder R=6mm, the gap between them is 0.6mm, α/2=45 °, lath sheet material is medium carbon steel thickness of slab δ=1mm.The fire-proof heat-insulating filler is an alumina silicate fibre band spraying amino expansion fireproof material.
The utility model has the advantages that owing to be that cylinder connects, the two sides symmetrical configuration can realize two-sided rolling, and has the same good decorative effect in two sides; It is little to wear and tear, and air-tightness is good, and is anticorrosive, and keying strength is good, and fire protecting performance is good, safety, and structure ﹠processes is reasonable, and is specious. Be suitable for hotel, senior market, shopping center, top restaurant and other is in the ornamental engineering of having relatively high expectations.
