Abstract
The utility model relates to a fireproof rolling shutter door which comprises a door post coated with a waterproof heat insulation material, a fireproof rolling shutter box body, a rolling shutter guide rail coated with a fireproof heat insulation board, a rolling shutter door sheet, and a fireproof seal piece; the door post coated with the waterproof heat insulation material is composed of a steel structure door post in the middle, the fireproof heat insulation board on the periphery, and a keel and a keel supporting piece in the middle; the keel and the keel supporting piece are adhered with the steel structure door post by an adhesive; the keel and the fireproof heat insulation board are fixed by a fastening piece; the upper part of the fireproof rolling shutter door is provided with the fireproof rolling shutter box body; the mechanism of the rolling shutter door sheet is arranged in the center of the box body; the seal piece is provided near an upper floor board; both sides of the upper floor board are provided with the fireproof heat insulation board and a light heat insulation material filled in the middle. Because the fireproof heat insulation board adopted by utility model is a light calcium silicate fireproof board whose dead weight is light, the weight of the whole component is decreased and the fireproof performance is unchanged in a long term; the light calcium silicate fireproof board is provided with a strong fireproof performance, which can cause the fireproof limit of the fireproof rolling shutter door system to reach more than four hours.
Description
Technical field:The utility model relates to a kind of fire resistance rolling shutter door, comprises the door pillar that coats fire-proof heat-insulating material, the fire curtain casing, coat the roller shutter guide rail of fire-proof heat insulation board, roller shutter door leaf and fireproof blocking spare, to reach the fire endurance that is complementary with the curtain body, the utility model belongs to the building fire protection technical field
Correlation technique:Existing fire resistance rolling shutter door at present only to the detection of preventing fires of curtain body, and to its corollary apparatus, does not all require as parts such as door pillar, casing, guide rail, closeouts, and its fire endurance far can not mate with the curtain body.Very fast distortion was until collapsing after its harmfulness was (1) door pillar, casing and guide rail are heated when fire, make the curtain body lose supporter and power set, thereby making whole fire curtain system lose due fire prevention cuts apart every effect, cause fire damage, at this problem, other materials such as adopting fireproof paint is arranged to its fire prevention cladding, to improve its fire endurance, but fire screen will often turn round, produce vibrations, fireproof coating easily comes off, and contains organic matter in the coating again, organic matter is rotten behind the 3-5, very easily comes off.What (2) adopt at present for closeouts is two-layer the combustion or difficult combustion inorganic plate, connects with lightgage steel joist, doses rock wool and reach certain fire endurance between two-layer sheet material, but experiment is found, during breaking out of fire, because the coefficient of thermal conductivity of two-layer sheet material itself is bigger, can be soon with the link lightgage steel joist in the middle of the heat transferred, make it produce distortion, this will make closeouts destroyed, until collapsing, lose the fire separation effect, can not lock the fire scope effectively, cause bigger loss.
Summary of the invention:The purpose of this utility model provides a kind of by fire curtain door pillar (7), fire curtain casing (10), coat the roller shutter guide rail (6) of fire-proof heat insulation board, the fire resistance rolling shutter door that roller shutter door leaf (9) and fireproof blocking spare (12) constitute makes the fire curtain system play the fire separation effect better.
The door pillar (7) that coats fire-proof heat-insulating material is by the steel work door pillar (7 ') of centre and fire-proof heat insulation board on every side (3) and middle keel (5) and grid bearer (5 ') formation; Keel (5) and grid bearer (5 ') bond with cementing agent (11) with steel work door pillar (7 '), and keel (5) and fire-proof heat insulation board (3) are fixing with securing member (1); Fire curtain casing (10) is arranged at fire resistance rolling shutter door top, the structure of cabinet shell is identical with the flameproof case of door pillar (7), there is the mechanism of coiling fire curtain door leaf (9) at casing (10) center, this is identical with prior art, the both sides of casing (10) respectively have a cover to coat the guide rail (6) of fire-proof heat insulation board, the nearly floor of going up has closeouts (12), by the channel-section steel keel (2) that are fixed on the floor, be fixed in the fire-proof heat insulation board (3) of lightgage steel joist (2) both sides and the light heat-insulating material (8) of middle filling and constitute, closeouts (12) has been located inorganic heat insulating mattress material (4) near last floor and following fire curtain casing (10).In the centre of the door pillar (7) that coats fire-proof heat-insulating material, except that being provided with keel (5) and grid bearer (5 '), the space still is filled with light heat-insulating material (8).
The material that above-mentioned member adopts, keel and grid bearer and lightgage steel joist can be made of steel or reinforced plastic, securing member adopts lightweight calcium silicates PLASTIC LAMINATED with bolt or nailing, fire-proof heat insulation board, and the light fire-proof heat-insulating material can adopt mineral wool, glass fiber, expanded vermiculite etc.
Adopt fire resistance rolling shutter door of the present utility model and correlation technique that following advantage is relatively arranged:
1. the calcium silicates PLASTIC LAMINATED has reduced the weight of integrated member from heavy and light.
2. calcium silicates PLASTIC LAMINATED and whole curtain body are in conjunction with solid and reliable, and its fire resistance remains unchanged for a long period of time.
3. the calcium silicates PLASTIC LAMINATED has superpower fire insulation performance, the fire endurance of fire resistance rolling shutter door was reached more than 4 hours, the fire endurance of door pillar body, casing, guide rail, closeouts is reached fully with the curtain body be complementary, make the whole fireproof performance of fire resistance rolling shutter door reach designing requirement.
