Description
Technical field
This utility model relates to fire resistant doorsets, particularly relates to a kind of fire resistant doorsets being provided with shirt rim.
Background technology
Fire resistant doorsets refer to play burning things which may cause a fire disaster the door of partition effect.The basic structure of fire resistant doorsets includes that a body, door body are provided with surfaces externally and internally layer and the fireprotection layer between surfaces externally and internally layer, and overcoat can be one or more layers.
Existing fire resistant doorsets have the disadvantage that so that door can carry out unobstructed unlatching, and door shuts the both sides of the width at back door with there is certain gap between doorframe, and the existence in this gap can cause fire resistant doorsets to decline the partition effect of burning things which may cause a fire disaster；Door body lower end is poor with the sealing effect between ground.
Utility model content
This utility model provides and a kind of can automatically carry out sealing with the gap between doorframe by the width of door when producing fire and lower end is with the good fire resistant doorsets being provided with shirt rim of the sealing effect between ground, solve the both sides of fire resistant doorsets width with between doorframe can gap and the problem that burning things which may cause a fire disaster is cut off effect decline that caused with the sealing effect difference between ground of the lower end of door.
More than technical problem is that and solved by following technical proposal: a kind of fire resistant doorsets being provided with shirt rim, including a body, described door body through-thickness is sequentially provided with interior surface layers, inner side fireprotection layer, outside fireprotection layer and outer surface layer, it is provided with atmospheric pressure cavity between described inner side fireprotection layer and outside fireprotection layer, it is filled with water in described atmospheric pressure cavity, described atmospheric pressure cavity all slidably connects the sealing strip that can stretch out a body along the width of door body along the both sides in door body width direction, and the lower end of described door body is provided with the elastic shirt rim on ground of can swiping.When producing fire, temperature produced by fire can cause the water evaporation in atmospheric pressure cavity to produce steam, the formation of steam can make the air pressure in atmospheric pressure cavity raise, the result that air pressure in atmospheric pressure cavity raises is the sealing strip that drives and be positioned at atmospheric pressure cavity both sides separately stretches out body from the side of the width of door body along the width of door body and abuts to doorframe, thus realizes the gap between this body fellow disciple's frame is carried out automatic-sealed.Atmospheric pressure cavity is filled with water, it is possible to when temperature is raised, the air pressure of air pressure intracavity can quickly raise and have enough thrust, simultaneously evaporation of water and can also play the effect of cooling.The lower end of door body can be sealed connected together by elastic shirt rim with between ground.
As preferably, between the described sealing strip of atmospheric pressure cavity both sides, it is provided with the position limiting structure preventing sealing strip from coming off from described atmospheric pressure cavity.It is prevented from accident and makes sealing strip abjection cause afunction, good reliability.
As preferably, described position limiting structure includes two connecting rods, one end of described two connecting rods links together with the described sealing strip of atmospheric pressure cavity both sides respectively, the other end is respectively equipped with spliced eye and connection-peg, described connection-peg is plugged in described spliced eye, described spliced eye is provided with inner retaining side, and described connection-peg is positioned at the part of spliced eye and is provided with the outer rib coordinated with described inner retaining side.Sealing strip can also be played support fixation by position limiting structure.
As preferably, described connecting rod is slided and is located in fairlead, and described fairlead is fixed together with described door body.The fairlead bar that is connected can play guide effect, prevents producing sealing strip above-below direction during the extrapolation sealing strip of the air pressure in atmospheric pressure cavity and tilts to stretch out and affect sealing reliability.
As preferably, described door body is provided with at least two bolt through described elastic shirt rim, described bolt thread connects the nut being pressed together elastic shirt rim with described door body, described nut includes the screwed hole section coordinated with described bolt, the hole wall of described screwed hole section is provided with along the axially extended groove of nut, and described groove runs through described screwed hole section.During installing/dismounting elasticity shirt rim conveniently." screwed hole section " refers to set that section threaded on nut.nullNut in the technical program is by offering groove in the threaded walls of screwed hole section，And groove runs through whole screwed hole section，If screw thread gets rusty or has foreign material，So during turning nut，The foreign material such as rust can be by exclusion to groove，Without the stuck screw thread that affects between nut and the screw thread of bolt according to normal orbiting motion、Thus cause the phenomenon of stripped thread to occur，Before twist-on nut，Some lubricating oil can be dripped in groove，After in nut twist-on to bolt，Unnecessary lubricating oil can be stored in groove，Play the function of pcrmanent lubrication，The long rear thread of evaluation time is got rusty，But as long as staggering slightly some positions between screw thread，Screw thread can be lubricated again by the lubricating oil being stored in groove，Screw thread is made to turn on easily，It is unlikely to stripped thread，Simultaneously because being designed with groove，Destroy the seriality of screw thread，So nut is not easy to loosen，Locking function can be higher.
As preferably, described groove is " V " shape groove.When nut is screwed on bolt, groove is oblique line with the line that contacts of the screw thread on bolt, and during rotation, the edge of groove is good with the scraping effect of foreign material to the rust on screw thread so that be less susceptible to stripped thread between nut and Hanging bolt.
As preferably, the angular aperture of described groove is 20 ° to 60 °.Can either ensure there are enough water environment capacities, have the intensity that ensure that Luo Ya is enough.
As preferably, the cell wall of described groove is provided with sword.Scraping effect to the rust on screw thread Yu foreign material when can improve nut rotation.
As preferably, described groove is three or four, and described groove is evenly distributed on the hole wall of described screwed hole section.When screw thread gets rusty or has foreign material on it, nut only need to rotate a less angle i.e. no more than 60 degree just can be discharged in groove by the foreign material such as rust, if uneven distribution, the angle that in foreign material are discharged to groove, the required angle rotated can be to be rotated than being uniformly distributed is big, namely anti-slip thread function do not have equally distributed good, if the quantity of groove is opened too much, the intensity of nut can be affected.
As preferably, described nut outer surfaces is axially sequentially provided with guiding area, operation area and crimping district, and the cross-sectional area of described guiding area, operation area and crimping district three becomes big successively, and described operation area is positive hexagonal prism.Hexagon is more general, is not required to special tool(s) and just this nut can be carried out twist-on operation.
This utility model has an advantage that when not producing fire, door body can compared with fire resistant doorsets the same, carry out opening and closing, when producing fire, it is possible to automatically lived so that fire resistant doorsets have preferably partition effect with the clearance seal between doorframe in door body width direction unobstructedly；Elastic shirt rim is set, it is possible to increase door body lower end is with the sealing effectiveness between ground.
