When a fire occurs, the second fireproof expansion rod 42 in the second accommodating cavity 41 absorbs heat and expands rapidly to support the inside of the outer frame profile 4, on one hand, the strength is increased, the deformation possibility is reduced, on the other hand, the temperature is reduced and the fire is retarded, and simultaneously, along with the continuous expansion of the fireproof expansion rod, the position of the extrusion groove 9 corresponding to the position is extruded out of the extrusion groove 9 along with the expansion, the extrusion groove 9 is filled between the window frame 1 and the window sash 2, on the one hand, the reinforcement and the sealing of the window frame 1 and the window sash 2 are achieved, on the other hand, the fire retardation and the heat insulation are achieved, and the fire resistance of the window frame 1 and the window sash 2 are ensured.

Referring to fig. 2 and 5, and secondly, to enhance the stability of the frame 1 and the sash 2 in the event of a fire. A plurality of mounting holes 44 can be formed in the side, close to each other, of the outer frame section bar 4 of the window sash 2 and the window frame 1, and the mounting holes 44 penetrate through the side wall of the outer frame section bar 4 and are communicated with the second accommodating cavity 41; fixing columns 45 are inserted into the mounting holes 44, hot melt adhesive is filled between the fixing columns 45 and the mounting holes 44 and used for fixing the fixing columns 45 in the mounting holes 44, one ends of the fixing columns 45 extend into the second containing cavity 41 and are fixed to the second fireproof expansion rods 42, and the other ends of the fixing columns 45 extend out of the mounting holes 44; a slot 451 is formed in the end portion of any one 45 of the two oppositely arranged fixed columns 45, and an inserting column 452 is formed in the other 45; the expansion of the fire-proof expansion bar can push the fixed columns 45 to move along the axes thereof to the inserting columns 452 of the two opposite fixed columns 45 to be inserted into the inserting grooves 451.

Referring to fig. 2 and 5, in a normal state, the fixing column 45 is fixed to the window sash 2 and the window frame 1 through the hot melt adhesive, and then one end of the fixing column 45 extends into the second accommodating cavity 41 to fix the fireproof expansion strip, so that the fireproof expansion strip is prevented from moving in the second accommodating cavity 41; when the intensity of a fire takes place, the thermosol melts, fixed column 45 can be for casement 2 or window frame 1 activity, simultaneously, the thermal expansion strip meets high temperature expansion, begin to promote corresponding fixed column 45 and tend to keep away from the direction motion that the second holds chamber 41, until the outer end of two fixed columns 45 that relative setting on window frame 1 and the casement 2 is mutual butt, realize inserting post 452 and peg graft in slot 451, can accomplish the further fixed of casement 2 and window frame 1 this moment, avoid casement 2 to break away from on window frame 1, strengthen its fire window's security performance.

The implementation principle of the energy-saving and environment-friendly heat-insulation firewall in the embodiment of the application is as follows: when a fire occurs, the first fireproof expansion rod 63 meets high temperature, the first fireproof expansion rod fills the whole first accommodating cavity 62 by rapid heat absorption expansion, deformation of the first accommodating cavity 62 is avoided, and a heat insulation and flame retardant effect is achieved, then, along with continuous expansion of the first fireproof expansion rod 63, the through holes 64 are extruded out of the positions, corresponding to the through holes 64, of the first fireproof expansion rod 63, the first fireproof expansion rod is gradually attached to the inner frame profile 5, the outer frame profile 4 and one side, far away from the first accommodating cavity 62, of the outer frame profile 5, the outer frame profile 4 and the first accommodating cavity 62, a fireproof and heat insulation adhesion layer is formed on one side, so that a fireproof and heat insulation effect is further achieved, flame combustion is blocked, the sealing performance between the profiles is enhanced, deformation of the profiles is reduced, and the fireproof performance of the window frame 1 and the window sash 2 is improved.

The second fireproof expansion rod 42 in the second accommodating cavity 41 absorbs heat and expands rapidly to support the inside of the outer frame profile 4, so that the strength is increased, the deformation possibility is reduced, the temperature is reduced, the flame retardance is realized, meanwhile, along with the continuous expansion of the fireproof expansion rod, the position of the extrusion groove 9 corresponding to the second fireproof expansion rod extrudes the extrusion groove 9 along with the expansion, the extrusion groove 9 is filled between the window frame 1 and the window sash 2, on one hand, the reinforcement and the sealing of the window frame 1 and the window sash 2 are realized, on the other hand, the flame retardance and the heat insulation are realized, and the fireproof performance of the window frame 1 and the window sash 2 is ensured.

In addition, the fixing column 45 is fixed to the window sash 2 and the window frame 1 through hot melt adhesive, and then one end of the fixing column 45 extends into the second accommodating cavity 41 to fix the fireproof expansion strip, so that the fireproof expansion strip is prevented from moving in the second accommodating cavity 41; when the intensity of a fire takes place, the thermosol melts, fixed column 45 can be for casement 2 or window frame 1 activity, simultaneously, the thermal expansion strip meets high temperature expansion, begin to promote corresponding fixed column 45 and tend to keep away from the direction motion that the second holds chamber 41, until the outer end of two fixed columns 45 that relative setting on window frame 1 and the casement 2 is mutual butt, realize inserting post 452 and peg graft in slot 451, can accomplish the further fixed of casement 2 and window frame 1 this moment, avoid casement 2 to break away from on window frame 1, strengthen its fire window's security performance.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
