Description
Technical Field
The utility model belongs to the technical field of prevent fire door, concretely relates to steel-wood combination prevents fire door safely.
Background
The fireproof door is a door which can meet the requirements of fire-resistant stability, integrity and heat insulation within a certain time; besides the function of a common door, the fire door has the functions of preventing the fire from spreading and the smoke from diffusing, can prevent the fire from spreading within a certain time, and ensures the evacuation of people.
The fireproof doors comprise a wooden fireproof door, a steel-wood fireproof door and the like; traditional fire door mainly solves thermal-insulated fire-resistant problem, and its intensity is than poor, and is impaired easily, and effect such as give sound insulation is also relatively poor.
Disclosure of Invention
An object of the utility model is to provide a stable in structure, fire prevention, explosion-proof and the effectual steel wood combination safety fire door that gives sound insulation.
In order to realize the technical purpose, the utility model discloses a following technical scheme: the utility model provides a steel-wood combination safety fireproof door, includes the door frame and installs the door leaf on the door frame, its characterized in that: the door leaf comprises a galvanized steel skeleton filled with fireproof rock boards, galvanized steel core boards, fireproof light calcium boards and high-density fiber panels are sequentially arranged and connected on two sides of the galvanized steel skeleton from inside to outside, the four sides of the galvanized steel skeleton are respectively connected with the four door leaf edge covering portions in a wrapping mode, and the four door leaf edge covering portions are welded and fixed.
Furthermore, the galvanized steel skeleton is formed by welding a plurality of galvanized steel profiles, and a plurality of cavities formed among the galvanized steel profiles are respectively embedded with the fireproof rock plates.
Further, the thickness of the galvanized steel core is 0.85mm. The thickness of the fireproof light calcium carbonate plate is 3mm. The thickness of the high-density fiber panel is 8mm.
Further, a stainless steel ribbon board is also arranged on the high-density fiber panel.
The utility model has the advantages that: adopt above-mentioned structure, overall structure is stable, fire prevention, explosion-proof and give sound insulation effectually.
In particular, the edge covering process is adopted around the door leaf, the fireproof rock plates are embedded in the galvanized steel framework, and the galvanized steel core plates connected in front and back are matched, so that the hardness and the sealing property can be enhanced, and the deformation can be prevented; the arranged light calcium fireproof plate can enhance the fireproof effect; and the high-density fiber panel can strengthen the effects of fire prevention, heat insulation and sound insulation, and the whole door leaf effect reaches the national standard of fire doors and has the effects of explosion doors and safety doors.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an exploded view of the middle door leaf of the present invention.
Detailed Description
As shown in fig. 1, the utility model relates to a steel-wood combined safety fireproof door, including door frame 1 and the door leaf 2 of installing on the door frame, door leaf 2 passes through hinge 3 and connects on door frame 1, installs tool to lock 4 on the door leaf 2, can lock door leaf 2 on door frame 1 through tool to lock 4. The doorframe 1 may be made of steel or fire-resistant wood, such as stainless steel plate having a thickness of 1.2 mm.
As shown in fig. 2, the door leaf 2 includes a galvanized steel skeleton 21 filled with fireproof rock plates, and a galvanized steel core plate 22, a fireproof light calcium plate 23 and a high-density fiber panel 24 are sequentially disposed and connected on two sides of the galvanized steel skeleton 21 from inside to outside. The galvanized steel skeleton 21 is formed by welding a plurality of galvanized steel profiles, and a plurality of cavities formed among the plurality of galvanized steel profiles are respectively embedded with the fireproof rock plates 25. The high-density fiber panel 24 is also provided with a stainless steel strip 26 for decoration and positioning reinforcement, and the stainless steel strip 26 is vertically arranged and is arranged at a position corresponding to the door lock.
The installation of each plate can adopt the following modes: (1) After the galvanized steel skeleton is welded, fireproof glue is coated, the fireproof rock core board (2) is embedded, the galvanized steel core board (22) is coated with the fireproof glue, then the galvanized steel skeleton (21) is bonded, the periphery of the galvanized steel core board is welded and fixed, and the galvanized steel skeleton is pressed on a cold press for more than 6 hours. (3) The fireproof light calcium plate 23 is pasted on the galvanized steel core plate 22 after being coated with fireproof glue and is pressurized for more than 6 hours. (4) The high-density fiber panel 24 is also coated with fireproof glue, and then is adhered to the fireproof light calcium board 23, and the periphery of the fireproof light calcium board is fixed by screws. (5) The stainless steel ribbon board 26 is adhered on the high-density fiber panel 24 by high-temperature glue and is welded and fixed with the surrounding edge. After each plate is installed in sequence, the periphery of each plate is wrapped and connected through four door leaf wrapping edges 27, and the four door leaf wrapping edges 27 are welded and fixed. After the installation is connected, overall structure is stable, and intensity is sufficient, and fireproof effect is good, reaches fire door national standard, and effect and the security performance that gives sound insulation simultaneously are all very good.
Further, the thickness of the galvanized steel core plate 22 is 0.85mm. The thickness of the fireproof light calcium board 23 is 3mm. The high density fiber panel 24 has a thickness of 8mm.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
