Description

Firm in structure's metal anti-theft fireproof door

Technical Field

The utility model relates to a metal anti-theft fireproof door with a firm structure, belonging to the field of anti-theft fireproof doors.

Background

Fireproof doors are doors that meet the requirements of fire resistance stability, integrity and thermal insulation over a period of time. The fire-proof partition is arranged between fire-proof partitions, evacuation stairwells, vertical shafts and the like and has certain fire resistance. The existing normally open fireproof door has the advantages that a small gap exists between the bottom surface and the ground, and due to the small gap, the bottom surface of the fireproof door can be easily worn by interaction with stone particles and sundries on the ground in the opening and closing process, so that the bottom of the fireproof door is easily damaged, and the fireproof work is affected.

In order to achieve the above object, the present utility model is realized by the following technical scheme: the utility model provides a metal anti-theft fireproof door with firm structure, its structure includes anti-theft fireproof door plant, anti-theft fireproof door plant rear end face one side is vertical to be equipped with the hinge rod, anti-theft fireproof door plant rear end face middle part is equipped with the pull handle, anti-theft fireproof door plant bottom has cup jointed supplementary fire-proof strip, anti-theft fireproof door plant bottom surface is equipped with one and accomodates the groove, supplementary fire-proof strip inboard is equipped with the activity and joins in the storage pole of accomodating the groove, accomodate and be equipped with the spring between pole top and the storage groove top, anti-theft fireproof door plant rear end face bottom has inlayed restriction bolt, the restriction bolt inner tip is joined in marriage and is accomodate the groove to run through and accomodate pole top, anti-theft fireproof door plant rear end face bottom still hinge is equipped with the safety cover that shields the restriction bolt.

Further, the auxiliary fire-isolating strip is made of stainless steel.

Further, the cross section of the auxiliary fire isolating strip is of a U-shaped structure.

Further, a monitor is arranged at the top of the front end face of the anti-theft fireproof door plate.

Further, a door closer is arranged at the top end of the anti-theft fireproof door plate.

Further, the fire control warning sign is pasted to the safety cover outer wall.

The beneficial effects of the utility model are as follows: when the anti-theft fireproof door plate is installed, the installation position of the anti-theft fireproof door plate can be higher than the height of an existing fireproof door, the gap between the bottom surface of the auxiliary fire isolating strip and the ground is increased, interaction abrasion between the auxiliary fire isolating strip and stone particles and impurities on the ground is prevented, when a fire disaster occurs, fire isolating is closed along with the anti-theft fireproof door plate, a protective cover can be opened by an escape person positioned on the back of the anti-theft fireproof door plate, then a limiting bolt is pulled out, a spring in a compressed state rebounds, the auxiliary fire isolating strip is driven to move downwards through a storage rod to be in contact with the ground, flame at the bottom is isolated, and fire isolating capacity is effectively improved.
