Description

Emergency access

The utility model relates to hugs room fire extinguishing and fire escape, particularly a kind of passage that is attached to exterior wall.

Chinese patent application 99109027 discloses a kind of exterior wall that is attached to, the emergency access of horizontal and vertical shape.It leaves hole on balcony partition or balcony floor, load onto to open and close in check door and lid, makes common balcony become the passage that can use when urgent.Wherein opening and closing function is to finish by the axle of controlled rotation.

The purpose of this utility model is that the technology that adopts another kind of control door leaf to open and close constitutes emergency access.

This purpose is achieved in that rotating shaft and the associated components thereof that adopts in the alternative institute of the automatically controlled breech lock reference document, and remainder is constant substantially.

So-called automatically controlled breech lock is meant that the break-make by electric current causes the adhesive and the release of electromagnet, and then door leaf is locked and release.

Embodiment and description of drawings are as follows.

Fig. 1 to Fig. 3 is the structure chart of automatically controlled breech lock.

Fig. 4 is the part figure of horizontal channel one end.

Fig. 5 is the part figure of Vertical Channel bottom.

Among Fig. 1, armature (4) is descended by adhesive during electromagnet (6) energising.Spring (5) is compressed.In the door bolt hole (2) on door bolt tongue (3) the insertion door leaf (1).So door leaf (1) is by breech lock.During electromagnet (6) outage, armature (4) is lifted by spring (5).Door bolt tongue (3) withdraws from door bolt hole (2).So door leaf (1) is unlocked.

Among Fig. 2, during electromagnet (6) energising, armature (4) rotates counterclockwise upwards around fulcrum (7) together with weight (8).Door bolt tongue (3) inserts in the door bolt hole (2).During outage, weight (8) drives armature (4) and falls.Door bolt tongue (3) withdraws from door bolt hole (2).

Among Fig. 3, armature (4) is fixed on the door leaf (1).Hold armature (4) during electromagnet (6) energising.Door leaf (1) is by breech lock.Otherwise then release.

More than among three width of cloth figure, except that door leaf (1) and the part on it, remainder is formed automatically controlled breech lock.It is other that automatically controlled breech lock is installed in door leaf (1), requires near aliging and fixing it.All the release of when outage among this three width of cloth figure, if release will switch on the time need only be adjusted part relative position among Fig. 1 and Fig. 2 by symmetric relation.In addition, all be to adopt electromagnet among this three width of cloth figure, also can adopt motor, at this moment need only become to fasten with a bolt or latch the required motion of tongue to the rotational transform of motor and get final product with reduction box and tooth bar etc.

Among Fig. 4, balcony door (13) and interior window (15) are arranged between room and the balcony (14), tempered glass or fence are housed above, as auxiliary protection.There is revetment (16) in balcony (14) outside, on it exterior window (not shown) can be installed.Have door opening and load onto the automatically reset escape door of bidirectional opening (10) on the partition wall (12) between the balcony (14).The other automatically controlled breech lock (9) that is equipped with of escape door (10).The outdoor ladder (11) of hugging is located on the flank wall and links to each other with balcony (14).At ordinary times, escape door (10) is by breech lock.Personnel can not walk up and down.When urgent, escape door (10) release.Personnel can evacuate ground to the building by balcony (14) and the outdoor ladder (11) of hugging.The fire fighter can enter along this passage and hug interior fire fighting and rescue.

Among Fig. 5, cat ladder (17) is housed on the partition wall (12).Hugging of balcony (14) has manhole and loads onto the cover plate (20) of being with hinge on the plate.At the other automatically controlled breech lock (9) that is equipped with of cover plate (20).Personnel can not walk up and down at ordinary times.Personnel are through manhole when urgent, and cat ladder (17, bottom (18), the gate facing the street (19) is evacuated ground to the building.

The utility model has the advantages that and adopt another technique construction to be used for the urgent logical of fire extinguishing and evacuation The road.

Claims

1, a kind of room fire extinguishing fire escape of hugging, form by the escape door (10) in balcony (14), balcony door (13), interior window (15), revetment (16), partition wall (12), the horizontal channel, outdoor cover plate (20), cat ladder (17), bottom (18) and the gate facing the street of hugging in ladder (11), the Vertical Channel (19) etc., it is characterized in that the other automatically controlled breech lock (9) that is equipped with of escape door (10) and cover plate (20).
