Door skin, distance piece, edge reinforcement and channel member can be made by mild steel or other steel plate.Door (movable or inactive) can have any outer thickness, such as 1.75 inches (44.5mm).Door micromicro is to be manufactured by No. 16 steel (16gauge steel), and thickness range is about 0.053-0.059 inch (1.35-1.50mm), so that the internal clearance of approximately 1.625 inches (41.3mm) to be provided between the inner surface at door skin.Each can have width and the height of any hope, but the present invention is used in particular for kissing gate, be that its width W is less than approximately 32 inches (0.81mm), preferably be not more than approximately 24 inches (0.61m), and wealthy family, be that its height or length H are greater than approximately 84 inches (2.13m), preferably to approximately 96 inches (2.44m) or more.
The main thermal insulation of door of the present invention is provided by gypsum panel, and this gypsum panel covers roughly whole width and basic whole height or the length that covers door of door substantially.Gypsum plank is also also referred to as plaster board, wallboard or dry wall, and manufactures panel-form by being pressed in two gypsum plasters between millboard.Gypsum is to be CaSO by chemical formula
4.2H
2the very soft Sulfates mineral matter that the calcium sulphate dihydrate of O forms, gypsum plaster produces by gypsum being heated to approximately 300 ℉ (150 ℃).Preferred gypsum plank is that the brand that can obtain from the U.S. Gypsum (United States Gypsum Company of Chicago, Illinois) of Chicago, Illinois, USA of thickness approximately 5/8 inch (16mm) is the product of Sheetrock Firecode Core Type X.
Advantage of the present invention is that labeled door can be controlled the ability arching upward to fire when labeled door arrives the temperature relevant to fire.Door of the present invention is configured to meet the door swing of ANSI A250.4-2011 of the He Gang of company of ANSI timber research institute promulgation and the standard of the physics endurance of distortion.The more important thing is, door of the present invention is configured to meet the standard by the positive banking fire test for door assembly of the UL10C of the Underwriters Laboratories Inc. issue of Illinois Northbrook.Men Yi side is exposed to gas burner source with specified temp and time.Not exposing an epidermis face to the open air, at least three parts of the side that deviates from thermal source of door are carried out temperature survey, and cotton pad is applied to crack, hole or other opening near in door or around with ad hoc rules interval.During flammability test, steel casement door skin through expanded by heating and towards thermal source, outwards arch upward and in the direction with door original plane quadrature at room temperature distortion up to approximately 8 inches (20cm) or more.When door is deformed with distortion at elevated temperatures, gypsum panel is held in place and is separated with the inner side of door skin by distance piece part, and this distance piece distributes stress to protect the integrality of gypsum panel.Because gypsum panel is frangible in a way, and because be exposed to high heat and make cover the paper performance degradation of gypsum panel and finally burn, so the last performance degradation of gypsum panel and breaking.Surprisingly,---for example approximately 24 inches (0.61m) wide door---is when above used when at kissing gate, gypsum panel allows enough heats via panel, to flow to the contrary door skin of non-exposed sides from exposing to the door skin of Combustion Source, to cause that this contrary door skin expands along with temperature and roughly as one man arches upward.This makes distance piece partly keep sufficient distance piece contact and (until 3 hours or more) keep gypsum panel in sufficiently long duration position and globality, to provide the heat insulation quality of hope before it is cracked.
Do not have gypsum panel of the present invention still to have the kissing gate of traditional thermal insulation barriers of higher insulation value not meet UL10C standard.Although do not wish to be bound by theory, believe that the low insulation value of gypsum panel allows additional heat to reach a non-skin that exposes to the open air, thereby allow the better controlled expansion of two skins during exposing to the open air.Although the exposed sides of door can reach the temperature over the about 1800-1900 ℉ of surrounding environment (1000-1050 ℃) after 30 minutes, the non-exposed sides of door of the present invention is no more than the temperature of surrounding environment approximately 450 ℉ (250 ℃).
Another advantage of the present invention is the tolerance of the heat to around transmitting at locking mechanism.Due to the impact that the maintenance lockset of door or the part of locking mechanism are especially easily heated and are transmitted, the present invention has introduced mineral wool part around in lockset region.By using flexible insulant material such as mineral wool part, near the lockset seat of dodge gate and near the free edge of inactive door, providing thermal insulation.C shape mineral wool part partly surrounds mortise lock or the locking mechanism on dodge gate.The elongated mineral wool part that extends to a bottom from header partly surrounds the locking bar inactive door.Mineral wool part or rock wool are that melting ore is at the temperature of about 1600 ℃, blow the smelting furnace product of air stream or jet to it.More advanced production technology is based on draw melting ore revolving at a high speed on spinning roller, in some degree with similar process for the preparation of cotton candy.Final products are that representative diameter is meticulous, the piece that is wound around fiber of 6 to 10 microns.Mineral wool can comprise adhesive.The mineral wool adopting in the present invention can comprise the mineral wool fiber that adopts modified urea to extend phenolic cured resin adhesive.Preferred mineral wool is the mineral wool that the trade mark that can obtain from the rock wool manufacturing company (Rock Wool Manufacturing Company of Leeds, Alabama) of Ritz, Alabama is Delta.
In order further to improve the tolerance performance that heat is transmitted, ceramic paper extends and covers the length of door roughly and be positioned at the side in the face of Combustion Source of door, contiguous lockset edge reinforcement.Ceramic paper stops the heat transmission in the part without gypsum panel of labeled door.Ceramic cardboard under door skin conventionally extend across reinforcement and with the imbricate of gypsum panel.In the present invention, adoptable ceramic paper is by aluminium silicon materials, to be manufactured the ceramic fiber products of paper and other sheet form, is generically and collectively referred to as ceramic paper herein.Ceramic paper has conventionally from the wide temperature application range of 1500 ℉ to 3000 ℉.Ceramic paper by clean, revolve the high-purity fiber process of spinning and form high flexibility sheet material.Ceramic paper comprises organic adhesive so that the processing intensity of increase to be provided in room temperature.The ceramic paper adopting in the present invention can be included in the refractory ceramic fibre (RCF) in acrylic acid and polymeric cementing agent.The Inswool2300 paper that the ANH refractory Company (ANH Refractories Company of Moon Township, Pennsylvania) in preferred ceramic paper Shi Kecong Pennsylvania's moon town obtains.
Believe using and arrange by being limited in the formation of a deformation time gap and opening and making door of the present invention there is good fire line of C groove reinforcement and additional mineral wool part and ceramic paper thermal insulation barriers.
