Abstract
The utility model relates to a part which is arranged inside a door and used for insulating fire, in particular to a door leaf. The integral type steel fireproof door leaf consists of a face plate (1), a back plate (4), rib strips (2), an upper closing plate (5), a lower closing plate (6) and fireproof filler (3); wherein the face plate (1) and the back plate (4) are respectively provided with a folding surface connected into a whole body; a plurality of rib strips (2) are respectively fixed and connected with the inner wall of the face plate (1) or the back plate (4); a rectangular body is formed by the face plate (1), the back plate (4), the folding surfaces of the face plate (1) and the back plate (4), the upper closing plate (5) and the lower closing plate (6); a cavity of the rectangular body is provided with the fireproof filler (3) which is molded filler formed by coagulating dispergated filler. Due to reasonable structure and design, the integral type steel fireproof door leafhas low cost, simple manufacturing technique, good integrity, high strength and excellent fireproof thermal insulation property. Furthermore, the fireproof door leaf can effectively isolate the fire when in fire, and meets the technical conditions of a fireproof door required by national standard GB 12955-2008 of the PRC.
Description
Technical field
The utility model relate to a kind of isolate fire the door in parts, especially door leaf.
Technical background
Chinese patent application number 03270444.5 discloses a kind of " extraordinary fire resistance steel door ", and its technical scheme comprises doorframe, door leaf, weather strip, it is characterized in that in the side that door leaf hinges pilot pin being housed, and the doorframe relative with pilot pin is provided with the pilot pin cave; The upside and the left and right sides of door leaf are fluted, inlay the fire proof seal bar in the groove.It is the labeled door that is suitable for use as architectural openings.Chinese patent application numbers 99216848.1 discloses a kind of " Fireproof door structure ", comprises: a pair of refractory slab suitable distance of being separated by; The pair of metal net is located at the refractory slab inboard; One framework is made up of some first, second skeletons that are longitudinal extension or horizontal expansion, and between two wire laths; Some insulating assemblies are located at framework inside, its both sides respectively with each refractory slab suitable distance of being separated by, have at least two insulating boards of the suitable distance of being separated by on it, and be convexly set in the some heat insulating strips on the outer rim; By this so that between adjacent each refractory slab and insulating board, between each insulating board, all can form a tabular compartment that prevents the rapid radiation of heat energy.
At present build a building, widely-used fire resistance steel door such as factory building, public place, because the harmful competition in market, the price of fire resistance steel door is pressed onto can not produces effective fireproof fire resistance steel door, add the incompatibility of traditional processing technology, make the market of labeled door almost not have qualified fire resistance steel door, make the people's lives and property be subjected to serious prestige association.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, provides a kind of simple in structure, with low cost and can effectively isolate the monolithic fire resistance steel door fan of fire.
Monolithic fire resistance steel door fan described in the utility model is made up of panel, backboard, rib, upper sealing plate, following shrouding and fire-proof packing, described panel and backboard respectively have a folding face that is connected as a single entity, rib is many, fixedly connected with the inwall of panel or backboard respectively, panel, backboard constitute a cuboid together with its folding face and upper sealing plate, following shrouding, be filled with fire-proof packing in its cavity, described fire-proof packing is the shape that the looses aftershaping filler that condenses.
Monolithic fire resistance steel door fan described in the utility model has very big difference with existing fire-proof door leaf in structure.At first be simple in structure, reject materials such as unnecessary composite panel and skeleton, only adopt steel panel, backboard etc. to form cuboid; Next is the setting of rib, rib is to fixedly connected with the inwall of panel or backboard respectively, can play booster action, makes panel, backboard combine effectively by condensing of filler, it connects respectively, can stop the transmission of heat between panel and backboard; The 3rd is fire-proof packing, filler of the present utility model is the shape that the looses aftershaping filler that condenses, this filler can counter plate, backboard is together with its folding face and upper sealing plate, the cuboid cavity that constitutes of shrouding is closely filled down, and in the process of aftershaping of condensing, panel, backboard are connected as a single entity together with its folding face and upper sealing plate, following shrouding, some ribs, become real monolithic door leaf.Compare with the filler of existing moulding in advance, how accurate that no matter makes is, between filler and the filler, always have the slit between filler and panel or the backboard, these slits will become the better channels that heat is transmitted, and make the thermal insulation of fire-proof door leaf and bulk strength reduce greatly.
Monolithic fire resistance steel door described in the utility model fan is because reasonable in design, makes with low costly, and manufacture craft is simple, formed door leaf good integrity, and the intensity height, heat insulation fire retardant is good.Can when fire takes place, isolate fire effectively, can satisfy the technical condition of State Standard of the People's Republic of China GB12955-2008 labeled door.
Description of drawings
Fig. 1 is a door leaf transverse cross-sectional view described in the utility model.
Fig. 2 is a door leaf longitudinal sectional drawing described in the utility model.
Among the figure: 1-panel, 2-rib, 3-fire-proof packing, 4-backboard, 5-upper sealing plate, shrouding under the 6-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being described further, is embodiment of the present utility model, and embodiment only is used to describe in detail the utility model, and does not limit it.
The described monolithic fire resistance steel door fan of present embodiment is by the panel 1 that has the folding face, backboard 4 and upper sealing plate 5, following shrouding 6 is formed cuboid, wherein be provided with some strengthened connection bar bars 2, part rib 2 is fixedlyed connected with the inwall 1 of panel, another part rib 2 is fixedlyed connected with the inwall of backboard 4, its objective is and to play the effect of strengthening door leaf, panel 1 and backboard 4 are not interconnected by rib 2, cut off heat transmission therebetween, in the cavity of above-mentioned cuboid, be filled with fire-proof packing, described fire-proof packing 3 is the shape that the looses aftershaping filler that condenses, its objective is in filling, filler 3 is the shape that looses, can be closely, the institute that seamless unoccupied place is filled up in the cuboid cavity has living space, isolated admirably heat is transmitted, after filling finishes,, make the plate of periphery all closely be connected as a whole with rib 2 by the aftershaping that condenses of filler 3.
Described fire-proof packing 3 can be Pengization perlite or vermiculite etc. and the blending body of adhesives, and in filling, filler 3 is for the shape that looses, and after filling finished certain hour, filler 3 moulding of condensing had the intensity of forging a good relationship.
