Fire-resistant windows are windows whose frames can meet fire resistance and fire-resistance integrity requirements within a certain period of time. Generally, openings or skylights on the exterior wall of a building where the fire separation distance is insufficient, firewalls or fire partitions in the building that require observation, and exterior wall openings that need to prevent the vertical spread of fire, should be used as spaces separated by firewalls. Fireproof windows will also be installed when lighting and ventilation are needed.

Fire-rated windows include a window frame and a sash installed in the window frame. The sash is usually hingedly installed in the window frame. In order to facilitate the installation of fire-resistant windows, the window frames and sash frames of fire-resistant windows are generally formed by splicing profiles. However, when a fire breaks out near a door or window, due to the limitations of the existing door and window materials, deformation and damage may easily occur under high temperatures, resulting in a sharp decline in the stability of the fire-resistant window and a gradual increase in gaps, which in turn leads to a significant decrease in sealing performance.

A plurality of mounting holes 44 can also be opened on the side of the outer frame profile 4 of the window sash 2 and the window frame 1 that are close to each other. The mounting holes 44 penetrate the side wall of the outer frame profile 4 and communicate with the second cavity 41; the mounting holes 44 The fixing posts 45 are inserted into them, and hot melt glue is filled between the fixing posts 45 and the mounting holes 44 to fix the fixing posts 45 in the mounting holes 44 . One end of the fixing posts 45 extends into the second cavity 41 And fixed to the second fireproof expansion rod 42, and the other end of the fixed column 45 extends out of the mounting hole 44; the end of any one of the two opposite fixed columns 45 is provided with a slot 451, and the other fixed column 45 is provided with a slot 451. 45 is provided with an inserting post 452; the expansion of the fireproof expansion rod can push the fixed post 45 to move along its axis until the inserting post 452 of the two fixed posts 45 is inserted into the slot 451.

Referring to Figures 2 and 5, under normal conditions, the fixing post 45 is fixed to the window sash 2 and the window frame 1 through hot melt glue, and then one end of the fixing post 45 extends into the second cavity 41 to fix the fire expansion strip to avoid fire expansion. The strip moves in the second cavity 41; when a fire occurs, the hot sol melts, and the fixed column 45 can move relative to the window sash 2 or window frame 1. At the same time, the thermal expansion strip expands when exposed to high temperature and starts to push the corresponding fixed column 45 away. The second cavity 41 moves in the direction until the outer ends of the two opposite fixing posts 45 on the window frame 1 and the window sash 2 abut against each other, so that the insertion posts 452 are inserted into the slots 451. At this time, the window sash 2 can be completed. Further fixation with the window frame 1 prevents the window sash 2 from detaching from the window frame 1 and enhances the safety performance of the fireproof window.

The implementation principle of an energy-saving and environmentally friendly heat-insulating firewall in the embodiment of the present application is as follows: when a fire occurs, the first fire-proof expansion rod 63 encounters high temperature and will rapidly absorb heat and expand to completely fill the entire first cavity 62 to avoid the occurrence of fire in the first cavity 62. deform and achieve the heat insulation and flame retardant effect. Then, as the first fireproof expansion rod 63 continues to expand, the first fireproof expansion rod 63 will squeeze out of the through hole 64 at the position corresponding to each through hole 64, and gradually adhere to the inner frame profile. 5. The outer frame profile 4 and the side connected away from the first cavity 62, on the one hand, make the connection between the three tighter, and on the other hand, the inner frame profile 5, the outer frame profile 4 and the first cavity can be connected One side of 62 forms a layer of fire-proof and heat-insulating adhesion layer, thereby further achieving the effect of fire-proof and heat-insulating, blocking the burning of flames, enhancing the sealing between profiles, reducing the deformation of profiles, and improving the fire protection of window frame 1 and window sash 2. performance.

The second fireproof expansion rod 42 in the second cavity 41 absorbs heat and rapidly expands to support the inside of the outer frame profile 4. On the one hand, it increases the strength and reduces the possibility of deformation. On the other hand, it cools down and is flame retardant. At the same time, with the continuous expansion of the fireproof expansion rod , the position corresponding to the extrusion groove 9 will be extruded out of the extrusion groove 9 with expansion and filled between the window frame 1 and the window sash 2. On the one hand, the window frame 1 and the window sash 2 are strengthened and sealed, and on the other hand, the flame retardant insulation is achieved. heat to ensure the fire resistance of window frame 1 and window sash 2.

In addition, the fixing post 45 is fixed to the window sash 2 and the window frame 1 through hot melt glue, and then one end of the fixing post 45 is extended into the second cavity 41 to fix the fireproof expansion strip to prevent the fireproof expansion strip from being in the second cavity 41 When a fire occurs, the hot sol melts, and the fixed column 45 can move relative to the window sash 2 or the window frame 1. At the same time, the thermal expansion strip expands when exposed to high temperature and starts to push the corresponding fixed column 45 to move away from the second cavity 41. , until the outer ends of the two opposite fixing posts 45 on the window frame 1 and the window sash 2 are in contact with each other, and the inserting posts 452 are inserted into the slots 451. At this time, the further fixing of the window sash 2 and the window frame 1 can be completed. , prevent the window sash 2 from detaching from the window frame 1, and enhance the safety performance of its fireproof window.

The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be covered by the scope of protection of the present application. Inside.
