Embodiment 1

[0040] Such as figure 1 As shown, a spliced ​​door frame for a fire door includes a square frame structure, the square frame structure includes two vertical frames 1 arranged in parallel at intervals, and the upper and lower ends of the two vertical frames 1 are respectively spliced ​​with horizontal The frame 2 and the bottom plate 4, that is, the horizontal frame 2, the two vertical frames 1 and the bottom plate 4 are spliced ​​to form a complete fire door frame structure. The spliced ​​fire door frame structure does not require additional welding work and riveting fixing structure, which is convenient for assemblers to operate, and is conducive to shortening the time of fire door frame assembly work, thereby achieving the purpose of improving the overall efficiency of fire door frame assembly operations.

[0041] combine figure 1 and figure 2 As shown, the vertical frame 1 includes a vertical main frame 11 and a vertical frame 12 integrally formed into a stepped structur...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that the plug-in fixing structures of the bottom plate 4 and the two vertical frames 1 are different, and the combination Figure 5 and Figure 6 As shown, the socket 71 on the vertical frame 1 is directly opened at the lower end of the side of the vertical frame 1, and the hole edge of the socket 71 extends toward the frame groove of the vertical frame 1 to form a ring-shaped fixing sleeve 711; When the base plate 4 is plugged and fixed with the two vertical frames 1 , the two ends of the base plate 4 are plugged into the two sockets 71 and extend along the fixing sleeve 711 to the inside of the frame groove of the vertical frame 1 .

[0053] combine Figure 5 and Figure 7 As shown, according to different types of fire doors and actual installation conditions, the bottom plate 4 also has different types, which mainly include two types of flat structure and stepped structure. When the bottom plate 4 is set t...

Abstract

The invention discloses a spliced door frame of a fireproof door and relates to the field of manufacturing of fireproof doors. The spliced door frame comprises two vertical frames, a horizontal frameand a bottom plate. The horizontal frame comprises a horizontal main frame and a horizontal blocking frame which are integrally formed to constitute a stepped structure; each vertical frame comprisesa vertical main frame and a vertical blocking frame which are integrally formed to constitute a stepped structure; inserting grooves are formed in the two ends of the horizontal main frame and the twoends of the horizontal blocking frame correspondingly, both the upper ends of the two vertical main frames and the upper ends of the two vertical blocking frames extend to form inserting plates, andthe inserting plates and the inserting grooves are in vertical inserted-connection fit; and inserting holes are formed in the lower ends of the two vertical frames correspondingly, the two ends of thebottom horizontally extend to form inserting blocks, and the inserting blocks and the inserting holes are in horizontal inserted-connection fit. Assembling personnel splice and fix the horizontal frame, the vertical frames and the bottom plate, thus assembling operation of the door frame can be achieved without extra welding or riveting operation, the assembling time of the door frame of the fireproof door is further shortened advantageously, and accordingly, the purpose of improving the overall assembling efficiency of the door frame of the fireproof door is achieved.

Description

technical field [0001] The invention relates to the field of fire door manufacturing, in particular to a spliced ​​door frame of a fire door. Background technique [0002] Fire doors refer to fire partitions that are installed in fire compartments, evacuation stairwells and vertical shafts, etc., and meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, fire doors also have the function of preventing and delaying the spread of fire within a certain period of time, which can buy time for personnel to evacuate. [0003] The existing authorized notification number is the Chinese patent of CN202990760U, which discloses a non-welded assembled door frame, including a horizontal frame and a vertical frame, and the horizontal frame and the vertical frame are spliced ​​to form a complete door frame structure, and the horizontal frame is located at the splicing place to be provi...
