Description

The door of band escape wicket

The utility model relates to a kind of door with the escape wicket, especially because the door of the band escape wicket that the big door leaf of gate doorframe body and double as escape wicket doorframe is formed.

The various rooms that people live are from not various doors.Especially medium-to-high grade playground, having relatively high expectations of opposite house, has fire prevention, fire-retardant, heat insulation function, in real life, no matter be common door or senior labeled door, all can have fire resistance property at short notice is that huge difference was arranged on the strick precaution time, the Men Douhuis all along with the prolongation of time gross distortion can occur in the scene of a fire of high temperature, problems such as switch difficulty, the red-hot air in scene of fire can make in the door in addition, the powerful pressure reduction of outer generation, seriously hindered the escape behavior of indicator of trapped personnel, will be between a little longer door of time and the doorframe because of the gross distortion mutual extrusion of being heated, make various door comprise that also high re door A all can't smooth opening, can cause bigger personal casualty loss.

Also there are many labeled door scientific and technological contents higher abroad, the time of keeping out fire can prolong greatly, but because its accuracy of manufacture is higher, the door and doorframe between after the extruding of other natural calamities such as high-temperature baking that is subjected to big fire or earthquake, block because of distortion between door and the doorframe, especially adopting hinges various more than 2 to connect manner between door and the doorframe, can cause bigger personal casualty loss too because profile variation seriously makes these doors be difficult for being opened easily.

The purpose of this utility model provide a kind of use more reliable, more easily under any fortuitous event, anyone effortlessly just can open the escape wicket above the door of this band escape wicket and flee for life, and under normal condition at ordinary times, also have good appearance and decorate and draught capacity, the emergency light deixis can also be provided and can be luminous in dark surrounds night bright indication escaping wicket position sign.

For achieving the above object, the door of band escape wicket of the present utility model is by gate doorframe body, the big door leaf of double as escape wicket doorframe and the single-point hinge composition that places on the escape wicket, the vent window opened downwards and the track of vent window are housed on big door leaf, the power supply of emergency light and emergency light is housed near the escape wicket, between gate doorframe body and the big door leaf is to flexibly connect by the hinge more than 2, on big door leaf, there is a shape similar, size differs big and escape wicket cavity similar, and the position of this cavity can make between escape wicket and the big door leaf enough big gap; Size between the doorframe on escape wicket and the big door leaf differs bigger, so just can not be because of the distortion between door and the doorframe, and the escape wicket of not opening at crucial moment, the section of wicket are the shapes that adopts the band convex; Multiple tracks fire prevention, fire-retardant, heat-insulating and sealing material are housed in the above, on the escape wicket, be furnished with the big door leaf of picture and use similar lockset, the escape wicket can only be opened in the inboard, room, and can't open from the outside, also can install unified decorative panel in the medial and lateral of door additional; So can not influence the switch of escape wicket yet, between escape wicket and big door leaf, single-point hinge articulating device is housed.

This single-point hinge articulating device can be that the little doorframe on big door leaf is on a left side or the left frame vertical direction and installs and have only a hinge, to escape and flexibly connect between wicket and the big door leaf, no matter big door leaf can not influence opening of gate toward that direction switch after little escape are opened.If it is back when wall is nearer that big door leaf is opened, wicket can opening and close automatically with the gate.

This single-point hinge articulating device can also be the little doorframe on the big door leaf be in or lower frame on horizontal direction the escape wicket that has only a hinge tie point is installed, after the escape wicket is opened in a horizontal manner, help creeping of indicator of trapped personnel, can play the effect of a foot bridge.

After adopting such structure, owing on big door leaf, be provided with cavity and vent window of opening and the emergency light of admitting the escape wicket downwards, during use, the size of escape wicket is far smaller than the preliminary dimension on the big door leaf, so just make between escape wicket and the big door leaf enough slits are arranged, to guarantee behind big door leaf generation gross distortion, the escape wicket also can effortless smooth opening, thereby the escape ability is improved greatly, in big door leaf and escape wicket, the outside all is to install identical decorative layer additional, and the Warning Mark that demonstrates escape wicket position in can the environment in dark is housed in big door leaf inboard; Multiple tracks fire prevention, fire-retardant, heat insulation protection material are equipped with in structure place in escape wicket projection.The phenomenon that fire spreads herein can not appear.On the escape wicket, also be equipped with and the big similar lockset of door leaf, between escape wicket and big door leaf, the method for attachment of single-point hinge type is housed, but the hinge position is installed difference is arranged, during use, can respectively be installed in left side or the limit of side on vertical mode the single-point hinge or be installed in the top in a horizontal manner respectively or following frame on, install in any case, can make indicator of trapped personnel easily, successfully open the escape wicket and flee for life.
