Description

A kind of the double of top sealing open fire resistant doorsets

Technical field

The utility model relates to fire proof construction technical field, in particular to a kind of the double of top sealing open fire resistant doorsets.

Background technique

Fire resistant doorsets refer to is able to satisfy the door that fire stability, fire resistant doorsets integrality and thermal insulation require within a certain period of time. It is the fire protection separators with certain fire resistance for being located at fire protection interval, emergency staircase, vertical shaft etc., in addition to tool Play the role of outside common door, has the function of preventing fire spreading and flue gas diffusion, the intensity of a fire can be prevented within a certain period of time Sprawling, it is ensured that evacuating personnel.

Currently, the Chinese patent that notification number is CN204299426U discloses a kind of fire resistant doorsets, it includes doorframe, and setting Door leaf on the inside of doorframe, and it is set to the fireproof door closer at the top of door leaf；And it is set to the fire prevention between door leaf and doorframe Hinge；And it is opened in the square through hole in the middle part of door body；Compound heat-insulation flame resistant glass is provided on the inside of the square through hole；And it sets The fireproofing door lock being placed on a door leaf；And it is set to the fire prevention bolt of door leaf bottom and top；And to close a flame damper another for setting Fire prevention Syn-position device on the door leaf of side.

Although this fire resistant doorsets solve the problems, such as that fireproof door frame side wall is bonded not tight enough with door leaf in the prior art, But still there are gaps between its two sides door leaf and doorframe top, after fire occurs, dense smoke is overflowed from the top of two sides door leaf, prestige It coerces to safety area and does not evacuate personnel.

Utility model content

The utility model is to provide a kind of the double of top sealing and opens fire resistant doorsets, and having effectively to open fire resistant doorsets for double Gap shielding at the top of the door leaf of two sides, prevents flue gas from overflowing, and will not influence the advantages of fire resistant doorsets are opened and closed.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of the double of top sealing open fire resistant doorsets, including top beam, bottom beam, the first column and the second column, the first column and First door leaf and the second door leaf are respectively articulated on second column, it further includes being arranged at top beam that top beam, which is equipped with door closer, Sealing device, the sealing device include

Fire resisting shutter, for blocking the gap between top beam and first door leaf and the second door leaf；

Retracting assembly, for furling fire resisting shutter, including the groove being opened on wall, groove is located at door closer Wall two sides, and groove is located at the first column side, and flushes with its top, rotating turret is equipped with volume along the vertical direction in groove Axis, spool both ends are connected with clockwork spring, and the fire resisting shutter coiling is on spool；

Driving assembly, for fire resisting shutter to be unfolded, including the drawstring and sliding block for drawing fire resisting shutter expansion, on top beam Sliding slot is offered, sliding slot is arranged along top beam length direction, and is located above the second door leaf, and downward, sliding block sliding is arranged notch In sliding slot, and slider bottom side wall offsets with the second door leaf, and top beam offers the through-hole being connected to sliding slot backwards to groove one end, Described drawstring one end is connected with fire resisting shutter, and the other end passes through through-hole and bypasses sliding block, second door leaf top affixed with top beam Portion is also provided with the holding tank for accommodating sliding block towards first door leaf one end.

By using above-mentioned technical proposal, on spool, spool both ends are connect fire resisting shutter coiling with clockwork spring, so that fire prevention Roller shutter keeps winding state in no external force, avoids it that from blocking at the top of fire resistant doorsets；When second door leaf is closed, top Offset with slider bottom side wall, sliding block driven to slide in sliding slot, drawstring is at this time around affixed with top beam after sliding block, then sliding block from When sliding slot one end slides to the other end, the mobile distance of drawstring is twice of sliding block, draws fire resisting shutter just from the first column side It is expanded to the second column side；Groove and door closer are located at wall two sides so that fire resisting shutter during folding and unfolding not It is influenced by door closer.

Further setting: the sliding slot is T-type sliding slot, and the sliding block is T-type sliding block, and slider top is opened in the horizontal direction Equipped with annular groove, drawstring is around on annular groove.

By using above-mentioned technical proposal, drawstring is around on annular groove, and when so that sliding block driving drawstring mobile, drawstring can be steady Surely cooperate with sliding block.

Further setting: the annular groove bottom turning set is equipped with axle sleeve.

By using above-mentioned technical proposal, drawstring one end is fixed, and when sliding block drives its movement, is occurred therebetween relatively sliding It is dynamic, it is easy to wear drawstring, setting axle sleeve rotates on annular groove, and drawstring moves synchronously always with axle sleeve, can be preferably Protect drawstring.

Further setting: the top beam is connected with guide groove backwards to door closer side, and guide groove is horizontally disposed, Notch downward, is embedded in guide groove at the top of the fire resisting shutter.

By using above-mentioned technical proposal, it is unfolded in guide groove, and along guide groove at the top of fire resisting shutter, can makes to prevent Fiery roller shutter is close to top beam, and after fire resistant doorsets closing, fire resisting shutter is close to first door leaf and the second door leaf, to preferably hide Keep off the gap between first door leaf and the second door leaf and top beam.

Further setting: being equipped with guiding axis along the vertical direction in the groove, guiding axis is flushed with metope, the fireproof rolling Curtain is around on guiding axis.

By using above-mentioned technical proposal, guiding axis is set, avoids notch side of the fire resisting shutter folding and unfolding in the process with groove It is impaired along direct friction.

Further setting: the fire resisting shutter towards drawstring one end be equipped with support rod, support rod along the vertical direction with fire prevention Roller shutter is affixed, and drawstring is connect with support rod.

By using above-mentioned technical proposal, the support rod being arranged along the vertical direction props up fire resisting shutter one end, drawstring band During dynamic support rod traction fire resisting shutter expansion, fire resisting shutter is made to keep smooth.

Further setting: being embedded with magnet at the top of second column, the support rod uses ferrimagnet.

By using above-mentioned technical proposal, after fire resisting shutter is fully deployed, magnet that support rod is embedded on the second door leaf Absorption, fits closely with the second door leaf and top beam, and fire resisting shutter is driven to be close to first door leaf and the second door leaf, enhances fireproof rolling The leakproofness of curtain.

In conclusion the utility model has the following beneficial effects:

1, it can prevent flue gas from overflowing effectively by double gap shieldings opened at the top of the door leaf of fire resistant doorsets two sides；

2, the wrapup procedure of fire resisting shutter will not influence the opening and closing of fire resistant doorsets；

3, when fire resistant doorsets are opened, fire resisting shutter automatic rolling will not impact the disengaging of people or cargo；

4, fire resisting shutter and drawstring be not easy to wear, long service life.
