Description

A kind of fire resistant doorsets of Initial Stage of Fire Smoke prevention

Technical field

The utility model is related to fire prevention, Initial Stage of Fire Smoke prevention field, more particularly to a kind of fire resistant doorsets of Initial Stage of Fire Smoke prevention.

Background technology

As the improvement of people's living standards, annual have a large amount of buildings to come into operation, a large amount of doors are used in architectural Construction inside fire security context, safe practice is widely applied on door, such as heat-insulated, fire prevention.Generally manufacture at present Fire resistant doorsets, such as CN2911148Y use in the door leaf at two end points of faying surface of doorframe and door leaf and have one Groove, fire-proof expansion seal strip is embedded in the groove.Because the groove by door leaf side periphery is embedded in the fire prevention of the fiery swelliong power of chance Expanding sealing strips so that fire proof sealing strip is immediately full of the narrow gap between doorframe and door leaf when door body meets fire.But when fire Calamity is not when in the initial stage of that flue-gas temperature is high, and sealing strip is notheated expansion and plays sealing function, so that Initial Stage of Fire poison gas can be climing Prolong multilayer even Zheng Dong buildings and cause harm.

Utility model content

The utility model aims to provide a kind of the double of Initial Stage of Fire Smoke prevention and opens fire resistant doorsets, with sound insulation, it is heat-insulated, to human body without Poison, and flameproof effect is good and other effects；Poison gas can be obstructed simultaneously spreads diffusion.

To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：

A kind of the double of Initial Stage of Fire Smoke prevention open fire resistant doorsets, including doorframe, door leaf, Fire-proof lock, fire-proof door closer and fire prevention are closed Page, door leaf includes left-hand door fan and right door leaf, and left-hand door fan and right door leaf are connected by hinge of preventing fires with doorframe respectively, door leaf and doorframe Shape adaptation, Fire-proof lock, fire-proof door closer are separately fixed on door leaf and doorframe, the described one end of left-hand door fan away from fire prevention hinge For step, the step includes two vertical planes and a curved surface, front and the back of the body that described two vertical planes are fanned with left-hand door respectively Face is adjacent, and curved surface head and the tail connect two vertical planes；The right door leaf is adapted to left-hand door fan shape, when door leaf is closed, left-hand door fan It is overlapping in stage portion with right door leaf；Flame retardant type sealing joint strip is covered with vertical plane on the outside of the curved surface and close door leaf.

It is preferred that, the Fire-proof lock is fixed on the vertical plane position on the inside of door leaf.

It is preferred that, the door leaf fills out inorganic foaming perlite core plate, lining steel plate, double-side fireproof plate and face in wooden frame Plate gluing composition.

It is preferred that, sealing joint strip is provided with the notch of the doorframe.

It is preferred that, the fire-proof door closer is located on the inside of door leaf.

It is preferred that, the front vertical of the vertical plane and door leaf.

It is preferred that, the curved surface is S-shaped curved surface.

The utility model is as a result of inorganic foaming perlite core plate, with sound insulation, heat-insulated, harmless to the human body, and Flameproof effect is good and other effects；Meanwhile, left and right door leaf is in the overlapped crack between a door and its frame and communicating door for foring relative dislocation of closed location The S-shaped passage of seam, and with flame retardant type sealing joint strip, the length of seal section is extended, stop that flue gas spreads into door；Enhance The entirety of building resists fire ability, reduces casualties and damage to property that fire is brought.

Brief description of the drawings

Fig. 1 is the utility model structure top view.

In figure：1- doorframes, 2- door leafs, 3- Fire-proof locks, 4- fire-proof door closers, 5- vertical planes, 6-S shapes curved surface, 7- flame retardant types Sealing joint strip.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality It is further elaborated with new.

As shown in figure 1, a kind of the double of Initial Stage of Fire Smoke prevention open fire resistant doorsets, including doorframe 1, door leaf 2, Fire-proof lock 3, fire prevention are closed Door device 4 and fire prevention hinge, door leaf 2 include left-hand door fan and right door leaf, and left-hand door fan and right door leaf pass through hinge and the doorframe 1 of preventing fires respectively Connection, door leaf 2 and the shape adaptation of doorframe 1, Fire-proof lock 3, fire-proof door closer 4 are separately fixed on door leaf 2 and doorframe 1, the left side The one end of door leaf away from fire prevention hinge is step, and the step includes two vertical planes 5 and a S-shaped curved surface 6, described two perpendicular Face directly 5 respectively with left-hand door fan front and back it is adjacent, S-shaped curved surface 6 connects two vertical planes 5 from beginning to end；The right door leaf and a left side Door leaf shape adaptation, when door leaf 2 is closed, left-hand door fan is overlapping in stage portion with right door leaf；The S-shaped curved surface 6 and close door leaf Flame retardant type sealing joint strip 7 is covered with the vertical plane 5 in outside.The Fire-proof lock 3 is fixed on the vertical plane 5 close to the inner side of door leaf 2 Position.The door leaf 2 fills out inorganic foaming perlite core plate, lining steel plate, double-side fireproof plate and panel gluing unit in wooden frame Into.Sealing joint strip is provided with the notch of the doorframe 1.The fire-proof door closer 4 is located at the inner side of door leaf 1.The vertical plane 5 and door The front vertical of fan 2.

During fire, evacuation personnel can firmly be pinned the fire resistant doorsets by Fire-proof lock, due to the fire resistant doorsets of the fire resistant doorsets All it is sealed between frame and fire resistant doorsets, and the notch inside fireproof door frame has added one layer of sealing strip, so working as the intensity of a fire When spreading rapidly, sealing strip for door frame can expand because of the rise of temperature, so that the gap air channel of fireproof door frame and fire resistant doorsets has The filling of effect ground.Meanwhile, left and right door leaf closed location is provided with flame retardant type sealing joint strip, can in crack between a door and its frame position effectively by the intensity of a fire and The impurity particles such as the toxic and harmful gas, smog and the dust that are produced in fire are completely cut off, thus reach protection take refuge personnel peace Escape entirely, and obstruct the effect of fire spreading.

Certainly, the utility model can also have other various embodiments, spiritual and its essence without departing substantially from the utility model In the case of, those skilled in the art can make various corresponding changes and deformation, but these phases according to the utility model The change and deformation answered should all belong to the scope of the claims appended by the utility model.
