[0025] like Figure 1-Figure 5 As shown, an energy-saving, heat-insulating and fire-resistant window comprises a frame body, wherein the frame body comprises an inner frame profile and an outer frame profile, glass is installed between the outer frame profile and the inner frame profile, and the inner frame profile and the outer frame profile are connected by a connector.

[0026] The frame body includes a window frame 1 and a window sash 2. The window frame 1 is installed in the wall, including an inner window frame 5 and an outer window frame 6, and a window frame glass 3 is installed between the inner window frame 5 and the outer window frame 6. The window sash 2 is hinged in the window frame 1, including an inner window sash 7 and an outer window sash 2, and a window sash glass 4 is installed between the inner window sash 7 and the outer window sash 2. The inner window frame 5 and the inner window sash 7 face indoors, and the outer window frame 6 and the outer window sash 2 face outdoors. Two heat insulation strips are arranged between the inner and outer window frames 6 and the inner and outer window sashes 2 to block heat transfer between the inner frame profile and the outer frame profile.

[0027] The connecting member includes a first connecting member 9, a second connecting member 10 and a third connecting member 11. The first connecting member 9 is provided on the side of the window frame 1 close to the wall, and the first connecting member 9 is fixedly connected to the inner window frame 5 and the outer window frame 6 respectively; the second connecting member 10 is provided on the side of the window frame 1 corresponding to the window frame glass 3, and the second connecting member 10 is fixedly connected to the inner window frame 5 and the outer window frame 6 respectively; the third connecting member 11 is provided on the side of the window sash 2 corresponding to the window sash glass 4, and the third connecting member 11 is fixedly connected to the inner window sash 7 and the outer window sash 2 respectively. The first connecting member 9 and the second connecting member 10 fix the positions of the inner window frame 5 and the outer window frame 6, and the third connecting member 11 fixes the positions of the inner window sash 7 and the outer window sash 2. The first connecting member 9 is straight, the second connecting member 10 and the third connecting member 11 are bent, such as L-shaped or other shapes, including a connecting portion 12 connected to the inner frame profile and the outer frame profile, and a supporting portion 13 bent at the outer glass, the supporting portion 13 contacts the outer glass and supports the glass to prevent the glass from falling after the outer window frame 6 is melted by fire. The first connecting member 9, the second connecting member 10 and the third connecting member 11 are all arranged at intervals, and the interval distance is 10cm-50cm, preferably 40cm.

[0028] The first connector 9, the second connector 10 and the third connector 11 are all metal sheets 22 with rock wool 23 on the surface, and the metal sheet 22 is preferably an iron sheet. Since the connector is made of metal, the thermal conductivity is good, and heat is easily lost through the connector. Therefore, the surface of the connector is covered with rock wool 23, which can block the spread of heat, effectively reduce the loss of heat, reduce the heat transfer coefficient of the house, and effectively improve the energy efficiency of the building.

[0029] In the outer frame profile and the inner frame profile, in order to increase the strength and stability of the door and window, a plurality of U-shaped steel liners 14 are arranged in the window frame 1 and the window sash 2. The opening of the U-shaped steel liners 14 faces the interior. The U-shaped steel liners 14 are filled with perlite 15. The perlite 15 has the characteristics of light weight, heat preservation, heat insulation and fire resistance, which can effectively block the conduction of heat and improve the heat insulation and fire resistance of the window frame 1. When a fire occurs and the outer frame profile and the inner frame profile melt in the fire, the perlite 15 and the steel liners keep the structural frame of the fireproof window intact, effectively reducing the possibility of glass falling off, thereby improving the fire resistance and safety of the window.

[0030] Fireproof expansion strips 16 are arranged on the inner walls of the outer window frame 6 and the outer window sash 2 as the first line of defense in case of fire. Fireproof expansion strips 16 are arranged on the sides away from the two insulation strips of the window frame 1 and the window sash 2 as the second line of defense in case of fire. The fireproof expansion strips 16 are 15 times adhesive expansion strips, which expand after encountering fire to block the gaps, thereby avoiding that all components are exposed to flames at one time and are quickly consumed, thereby extending the fire resistance time.

[0031] In order to ensure the sealing effect between the window frame 1 and the window sash 2, an EPDM rubber strip 17 is provided between the window frame 1 and the window sash 2. When the window sash 2 is closed, the EPDM rubber strip 17 can seal the window frame 1 and the window sash 2.

[0032] Fireproof glass pads 18 are installed on the side walls of the window frame glass 3 and the window sash glass 4. The fireproof glass pads 18 are installed between the side edges of the glass and the fixed parts of the connectors to ensure uniform force areas between the frame and the glass, while avoiding hard contact between the glass and the frame, reducing the risk of glass bursting.

[0033] A bead 19 is installed on the inner side of the inner window frame 5 and the inner window sash 7, at the edge of the glass. In the bead 19, fireproof cotton strips 20 are fixedly installed on the edges of both sides of the glass. When a fire occurs, heat is isolated from being conducted from the outside to the inside through the gap between the glass and the profile, thereby preventing the spread of the fire. Fireproof positioning strips 21 are used to seal the glass and the profile at the edges of the glass and the outer window frame 6, the outer window sash 2, and the glass and the bead 19.

[0034] 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 variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
