Description

Fireproof door frame split steel sleeve inserting structure Technical Field The utility model relates to the technical field of fireproof door frames, in particular to a split steel sleeve splicing structure of a fireproof door frame. Background In most public places such as hospitals, schools, super-market places and workshops, fireproof doors are arranged, namely doors which can meet the requirements of fire resistance stability, integrity and heat insulation in a certain time, and the doors are fireproof partitions with certain fire resistance, such as fireproof partitions, evacuation stairways, vertical shafts and the like, and the fireproof door frames are needed in the installation process of the fireproof doors. The fireproof door is attractive at present, a fireproof door frame and a sheath form are adopted, a solid wood sheath or an aluminum-plastic plate sheath is adopted before, and the problems of low structural strength, easiness in abrasion and the like exist, so that the steel sheath form is widely adopted nowadays. The steel sheath has the advantages of high structural strength, abrasion resistance, easy cleaning and long service life, and is widely used. The installation of traditional steel sheath is generally all to confirm entrance to a cave thickness earlier, then fixes sheath and door frame together, then installs in the entrance to a cave together, especially two sides package mouths mode together, and this kind of mode is more strict to entrance to a cave thickness requirement, can exist the gap between sheath and the wall body after the general installation is accomplished, still has to handle the gap, and the gap that the error is big, and the processing gets up the degree of difficulty big, both waste time and influence work efficiency, and aesthetic property receives the influence, and the installation effect is not good. Disclosure of utility model The utility model aims to provide a split steel sleeve splicing structure of a fireproof door frame, which adopts a splicing mode, the splicing depth can be adjusted until the split steel sleeve is spliced in place, the structure is simple, the installation process is simple, convenient and quick, the splicing seam is compact and attractive, and the installation effect is improved.
