Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a complete fire door for the problem that the existing fire doors cannot prevent the fire and smoke from overflowing from the gap of the door, and the fire resistance or high temperature resistance of the fire door as a whole is not strong. The door with fire protection function can not only prevent the door body from being deformed by heat after being caught on fire, but also effectively prevent the fire and smoke from overflowing

Embodiment 1

[0016] As shown in the figure, a steel heat-insulating fireproof door is made. The door is composed of a door frame 1 and a door leaf 2. The door frame 1 and the door leaf 2 are connected by a hinge 3. The door leaf 1 is provided with a handle 4 and a door lock 5. The case of the door frame 1 is made of cold-rolled galvanized steel; the inside of the door frame 1 is poured with cement mortar 6; wherein the cement mortar 6 is prepared by cement, sand and expanded perlite in a ratio of 1:2:5; the door leaf 2. It is composed of skeleton 7, door leaf panel 8 and composite fireproof door core board 9, in which the skeleton 7 and door leaf panel 8 are made of cold-rolled galvanized steel plate. The cladding frame 7 and the composite fireproof door core board 9 make the door leaf 2; the door frame 1 in contact with the door leaf 2 is also mounted with a fireproof expansion sealing sheet 10, and the hinge 3 is a fireproof concealed hinge installed. At the same time, the door frame 1 an...

Embodiment 2

[0018] Further, on the basis of the steel heat-insulating fire door made in Example 1, the fire door made is a mother-child fire door or a double fire door, and a cover seam 13 is installed between the two door leaves; the cover seam 13 is composed of cold-rolled galvanized steel frame 14, inorganic fireproof board 15, fireproof expansion sealing strip 16 and mounting plate 17; inorganic fireproof board 15 is installed in cold-rolled galvanized steel frame 14, and The steel plate frame 14 is vertically fixedly connected, and a plurality of interlaced long holes 18 are dug on the mounting plate 17, and the fireproof expansion sealing strip 16 is installed in the long holes 18 on the mounting plate 17. 17 is fixedly installed on the side of a door leaf among two door leaves. Promptly make steel heat insulation fire door of the present invention.

Abstract

A steel thermal-insulation fireproof door comprises a door frame and door leaves which are connected through hinges. A handle and a door lock are arranged on the door leaves. The fireproof door has the advantages expanded perlite are used as main materials of cement mortar in the door frame, re-expansion can be hard even if the door frame is on fire and heated, and accordingly, the heating and deformation of the door frame can be prevented; a framework and a plate of the door leaves are made of galvanized steel sheets, a door core is made of fireproof materials, and accordingly, the fireproof thermal-insulation effect can be achieved to a large extent; a fireproof door closing unit is arranged between the door frame and the door leaves, and the door leaves can be closed timely effectively, accordingly, the fire behavior and the hot gas can be blocked; meanwhile, the hinges, the lock and a door mirror are made of fireproof materials, so that a good fireproof thermal-insulation effect can be achieved through the overall action; a seam covering plate is added between the door leaves, fireproof expansion seal strips are arranged on a connection plate, and accordingly, the spreading of the fire behavior or smog can be prevented well.

Description

technical field [0001] The invention relates to a fireproof door, in particular to a steel heat-insulating fireproof door. Background technique [0002] 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 located in fire compartments, evacuation stairwells, vertical shafts and other fire partitions with certain fire resistance. In addition to the function of ordinary doors, it also has 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 personnel. [0003] In the existing fire doors, the door leaf structure adopts the method of filling material in the hollow door leaf, and the filling material is generally rock wool, expanded perlite and the like. Due to design and structural problems, such fire doors are not easy to prevent fire and smoke from overflowing from the gaps in ...
