The embodiment discloses a fire door closing-in structure, which has the advantages of simple structure, convenient installation, good appearance quality and effective improvement of construction efficiency. Fig. 1 shows a horizontal sectional structure of the closing-in structure of the fire door.
Referring to fig. 1, the fire door closing structure includes: a fireproof door frame 21, a steel sheet 3, a flame retardant plate 4 and a sheath 5. The fireproof door frame 21 is fixed on one side of the wallboard door opening, as shown in fig. 1, a door leaf 22 is further arranged on the fireproof door frame 21, and one side edge of the door leaf 22 abuts against the fireproof door frame 21 to form a fireproof door structure together with the fireproof door frame 21. The steel sheet 3 is fixed to be pasted on the surface of the wallboard door opening, so that a good reinforcing effect can be achieved on the wallboard door opening, and one side of the steel sheet 3 is abutted against the fireproof door frame 21. The fire-retardant board 4 bonds in the outside of steel sheet 3, selects to use 12mm thick fire-retardant board 4 in this embodiment, can realize the fire behavior that this fire door binding off structure required well on the one hand, on the other hand can also reduce construction process, civilized construction in order to protect the site environment. In addition, a sheath 5 is fixedly arranged on the outer periphery of the flame retardant panel 4, and in this embodiment, a sheath 5 with a thickness of 1.2mm and a width of 11cm is selected. The sheath 5 is of a bent structure, one side of the sheath is fixed on the surface of the wallboard 1, the other side of the sheath is abutted to the fireproof door frame 21, and the steel sheet 3 and the flame retardant plate 4 can be wrapped in the sheath 5, so that the external line of the fireproof door closing-in structure is more attractive, and better appearance quality is achieved.
After the wall construction is completed, the steel sheet 3 is installed on the surface of the wallboard door opening to strengthen, the fireproof door frame 21 is installed on one side of the wallboard door opening, the fire-retardant plate 4 is adhered to the surface of the steel sheet 3, and finally the sheath 5 is fixedly arranged on the periphery of the fire-retardant plate 4 to finish the closing-in of the fireproof door. The setting and the connected mode between each structure of this fire door binding off structure are comparatively simple, and the installation procedure is simple and convenient, can save the manual work, reduces construction cost, effectively improves the efficiency of construction.
In the embodiment, the sheath 5 and the wallboard 1 are fixed by self-tapping nails, and the self-tapping nails have higher hardness and strength, and the locking mode is simple and convenient and easy to operate. The self-tapping nails are adopted to fix every 50cm on the sheath 5, so that the connection between the sheath 5 and the wallboard 1 can be ensured to be more stable, the stability of the whole structure of the fireproof door closing-in structure is further ensured, and good appearance quality is achieved.
