Description

A new type of fire door

technical field

The utility model relates to the technical field of fire doors, in particular to a novel fire door.

Background technique

A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. Among them, the overall firmness of the fire door, the fire resistance of the door frame and the door leaf are the key factors to evaluate the quality of the fire door. Existing fire doors generally include a door frame and a door leaf, and the door leaf is composed of a fire resistant outer cladding decorative plate. In some special occasions, the fire doors of the existing structure cannot meet the use requirements. Therefore, a new technical solution should be provided to solve the above problems.

Contents of the invention

The purpose of the utility model is to provide a fireproof door with reasonable structure and good use effect.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A new type of fire door, comprising a steel door frame and a door leaf, the side of the door leaf is movably connected to the door frame through a fireproof hinge, a sound insulation strip and a smoke prevention strip are provided between the door frame and the door leaf, and the door leaf includes refractory filler layer, the refractory plate layer on both sides of the refractory filler layer and the surface decoration layer coated outside the refractory plate layer, a rectangular support frame is arranged around the refractory filler layer, and the refractory filler layer is provided with a "well" shape Supporting the frame, the exterior of the surface decoration layer is coated with a base layer and a nuclear radiation-resistant paint layer in turn, and a small fire door and window is installed on the door leaf, and a sealing strip is provided around the frame of the small fire door and window.

Further technical solutions:

The small fire doors and windows are connected with the door leaves by spring hinges.

Each end of the "well"-shaped support frame is fixedly connected with the rectangular support frame.

The nuclear radiation-resistant paint layer includes a radiation-resistant base material and radiation-absorbing pigments and fillers.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

1. The fireproof door of the present invention is provided with a sound-insulating strip and a smoke-proof strip between the door frame and the door leaf. The sound-insulating strip plays the role of sound insulation, and the smoke-proof strip blocks the flow of smoke when it is on fire.

2. The fireproof door of the present invention is provided with a "well"-shaped support frame in the refractory filler layer, and the "well"-shaped support frame can be integrated with the rectangular support frame around the refractory filler layer, increasing the refractory filler layer As well as the overall strength of the fire-resistant door, prolonging the service life.

3. The fire door of the present invention is coated with a base layer and a radiation-resistant paint layer on the outside of the surface decoration layer in sequence, so that the fire door of the present invention has good radiation resistance and wide application range.

1. The fire door of the present utility model has a small fire door and window installed on the door leaf. In some cases, it is only necessary to open the small fire door and window instead of the whole fire door. occasion. Sealing strips are installed around the outer edge of the door leaf and the frame of the small fire-fighting doors and windows, and the sealing strips are made of fire-proof expansion materials. Such structural design can enhance the sealing and fire-proofing of the fire-fighting door of the present utility model.
