In order to achieve the above object, the technical solution of the present invention is: a mounting structure of a fire-resistant window comprises a graphite polyphenyl support body, an auxiliary frame, an indoor window board, a waterproof air-isolating film, a waterproof air-permeable film, a prepressing expansion band and a flashing; an auxiliary frame is fixedly arranged on the outer end face of the wall body at the reserved hole, and a graphite polyphenyl supporting body wrapping the auxiliary frame is fixedly arranged at the outer end of the auxiliary frame; the auxiliary frame and the graphite polyphenyl supporting body are fixedly provided with a window frame and a window board; a waterproof air-isolating film is fixed at the indoor corner of the wall body and the window frame; heat preservation blocks are fixed among the indoor section bar, the outdoor section bar and the graphite polyphenyl support body of the window frame; waterproof breathable films which are not interrupted are fixed between the outdoor ends of the auxiliary frames, the outdoor ends of the walls and the lower ends of the heat preservation blocks and the graphite polyphenyl supporting bodies, and prepressing expansion belts are fixed at corners between the flashing plates and the graphite polyphenyl supporting bodies.
Further preferably, the sub-frame comprises a plurality of rectangular support section bars and four equilateral right-angle connectors; the section of the side of the equilateral right-angle connecting piece is a rectangle with the same shape as the section of the strip-shaped supporting section bar; the strip-shaped supporting section bar and the equilateral right-angle connecting piece are respectively made of high-density graphite polystyrene; one end of the strip-shaped supporting section bar is a tenon, and the other end of the strip-shaped supporting section bar is a groove matched with the tenon; one end of the equilateral right-angle connecting piece is a tenon, and the other end of the equilateral right-angle connecting piece is a groove matched with the tenon; the four corners of the auxiliary frame are equilateral right-angle connectors, one or more strip-shaped supporting section bars are arranged on the vertical frame, and one or more strip-shaped supporting section bars are arranged on the transverse frame; the groove and tenon connection or the tenon and groove connection between the adjacent strip-shaped supporting section bars is fixed in an adhering way, and the groove and tenon connection or the tenon and groove connection between the adjacent strip-shaped supporting section bars and the equilateral right-angle connecting piece is fixed in an adhering way. The middle of the vertical frame and the horizontal frame of the auxiliary frame adopts a strip-shaped supporting section bar, the corner adopts an equilateral right-angle connecting piece, the corner is connected without a gap, the strength is high, no crack exists, the heat insulation performance is good, and the service life is long. The middle strip-shaped supporting sectional materials and the equilateral right-angle connecting pieces are connected and bonded fixedly through the tenons, the fixing structure is firm, the joints are not prone to cracking, and the service life is further prolonged. One or more strip-shaped supporting section bars can be selected according to the lengths of the vertical frame and the transverse frame of the auxiliary frame in the middle, the auxiliary frame with any size can be butted to form the required auxiliary frame, and the installation is very convenient.
It is further preferred that the slot and tongue of the elongate support section and equilateral right-angle connector are open at an intermediate position at one end of the chamber. The profiles do not need to be inserted into the grooves and the tenons, so that the installation is simple and convenient, time and labor are saved, and the grooves and the tenons are not easy to damage during connection; because the interior of the room has no visible surface, only one connecting gap can be seen at the visible position outside the room, and the appearance is attractive.
The window adopting the mounting structure is an externally-hung mounting structure, the graphite polyphenyl support body is mounted on the outer side of the wall body of the opening, and the waterproof air-isolating film and the waterproof air-permeable film are mounted. When a fire disaster occurs, the graphite polyphenyl supporting body can well block the fire, the waterproof air-isolating film prevents hot air from entering, and then the fire disaster is blocked, and particularly, the joint of the corner of the auxiliary frame supported by high-density graphite polystyrene is seamless, the sealing performance is good, and the auxiliary frame is not easy to burn. In a word, the window adopting the mounting structure has good heat insulation performance, good sealing performance, difficult burnthrough and good fireproof performance. Still compare steel and aluminum alloy material's connecting piece, the utility model discloses it is low to transfer heat, no longer causes the injury to the human body because of metal surface temperature.
The graphite polystyrene board heat insulating layer belongs to B1 grade fireproof material, and the auxiliary frame is made of high density graphite polystyrene material. Meets the regulation of GB50016-2014 'fire-proof code for building design', can meet the requirement of building heat preservation, can effectively prevent flame spread and smoke permeation when a fire disaster happens, reduces the damage of the fire disaster, and provides guarantee for life and property.
