[0002] In view of fires in high-rise buildings, corresponding fire prevention measures should be taken during the design process of the building to prevent fires and reduce the harm of fires to life and property. Fireproof windows are one of the commonly used fireproof building structures. Fireproof windows generally refer to windows composed of outer frames, inner panels, and fireproof glass. The outer frames are filled with fireproof materials to isolate and prevent the spread of fire. Fireproof windows are generally used on the exterior walls of buildings to separate indoor space from the outdoor natural environment.

[0034] Next, the steel heat-insulating fireproof window in this exemplary embodiment will be further described.

[0035] In the embodiment of the present application, the fireproof window is configured to be composed of a plurality of fixed windows and at least one movable window. The fixed windows can enhance indoor lighting, and the movable windows can be opened and closed to increase indoor ventilation. The fixed window includes a first fixed outer frame 11 and a first heat-insulating fireproof glass 12, wherein the first heat-insulating fireproof glass 12 is embedded in the first fixed outer frame 11; the movable window includes a second fixed outer frame 21, a second heat-insulating fireproof glass 22 and an inner fan 23, wherein the second heat-insulating fireproof glass 22 is embedded in the inner fan 23, and the top of the inner fan 23 is hinged to the inner top of the second fixed outer frame 21 through a hinge 24, and the inner fan 23 is connected to the second fixed outer frame 21 on opposite sides adjacent to its top through an opening and closing mechanism 300. The top of the inner fan 23 is hinged to the inner top of the second fixed outer frame 21, so that the movable window is a floating window that opens outward and upward, and is pulled inward and downward when closed, so that the gravity unlocking structure can unlock and close the window.

[0036] The opening and closing mechanism 300 includes a fixed seat 3, a base 4 and a movable rod 5. The fixed seat 3 is fixed to the inner fan 23, the base 4 is fixed to the second fixed outer frame 21, one end of the movable rod 5 is rotatably connected to the fixed seat 3, and the other end of the movable rod 5 is slidably connected to the first slide groove 41 provided in the base 4 and locked with the first slide groove 41 through an elastic plug-in structure; the inner fan 23 or the second heat-insulating fireproof glass 22 is pushed or pulled, and one end of the movable rod 5 slides up and down in the first slide groove 41 to open or close the window. The base 4 is also provided with a temperature-sensitive glass bead 9 and a gravity unlocking structure. The gravity unlocking structure is located on one side of the first slide groove 41 and opposite to the elastic plug-in structure. The temperature-sensitive glass bead 9 is arranged at the bottom of the gravity unlocking structure and abuts against the gravity unlocking structure, and the temperature-sensitive glass bead 9 is exposed to the outside of the base 4.

[0037] The temperature-sensitive glass beads 9 are provided to support the gravity unlocking structure, and a certain amount of heat-sensitive colored expansion liquid is filled inside the temperature-sensitive glass beads 9. When a fire occurs, the liquid expands due to heat and the pressure increases. When it reaches a specified value, the temperature-sensitive glass beads 9 burst, and the gravity unlocking structure loses weight and moves downward, abutting against the elastic plug-in structure, so that the elastic plug-in structure is unlocked from the first slide groove 41, and the movable rod 5 moves downward in the first slide groove 41 to pull the second heat-insulating fireproof glass 22 to close, thereby realizing automatic window closing in fire.

[0038] As an example, the first slide groove 41 is opposite to the fixed seat 3 and is located at the edge of the base 4 close to the outdoor side. The top of the first slide groove 41 is provided with a plug-in hole facing the indoor side; the elastic plug-in structure includes a slider 61, a plug-in column 62 and an elastic member 63. The slider 61 is hinged to one end of the movable rod 5, and the slider 61 is slidably connected in the first slide groove 41; the slider 61 is provided with a groove on the side facing the plug-in hole, the plug-in column 62 is slidably arranged in the groove, and the elastic member 63 is located between the end of the plug-in column 62 away from the plug-in hole and the groove. The first slide groove 41 is arranged close to one side edge so that the other side has enough space to accommodate the gravity unlocking structure and the temperature-sensitive glass bead 9. The slider 61 is slidably connected to the first slide groove 41 and is hinged to the movable rod 5 to limit the moving end of the movable rod 5 so that it can only move up and down along the first slide groove 41. Through the plug-in column 62 and the elastic member 63, when the slider 61 moves to the plug-in hole, the plug-in column 62 is extended and inserted into the plug-in hole under the action of the elastic member 63 to limit and lock the movable rod 5, so that the movable rod 5 does not move, and then fixes it in this position after the window is opened. The elastic member 63 is a compression spring 82.

[0039] As an example, a second slide groove 42 is provided in the base 4, the second slide groove 42 is arranged adjacent to the first slide groove 41, and the second slide groove 42 and the first slide groove 41 are connected to each other through the plug hole. That is, the plug-in column 62 can be inserted into the second slide groove 42 after passing through the plug hole, so that the gravity unlocking structure in the second slide groove 42 can unlock it.

[0040] As an example, the gravity unlocking structure includes a U-shaped gravity block 71 and a reset block 72, wherein the open end of the U-shaped gravity block 71 faces the first slide groove 41; the U-shaped gravity block 71 is composed of a connecting block and two moving blocks relatively connected to the two ends of the connecting block, wherein one of the moving blocks is placed on the top of the temperature-sensitive glass bead 9, and the distance between the other moving block and the plug-in hole is equal to the height of the temperature-sensitive glass bead 9. Through the above structure, when the temperature-sensitive glass bead 9 is broken, the weightlessness of the moving block supported by it drives the U-shaped gravity block 71 to move down as a whole by the length of the temperature-sensitive glass bead 9, and the other moving block also moves down by the same length, just moving down to be opposite to the plug-in column 62, that is, the plug-in column 62 is squeezed inward during the downward movement, and the plug-in column 62 is retracted into the first slide groove 41 by the squeezing force, and after being unrestricted, it slides downward along the first slide groove 41 under its gravity, thereby driving the window to close.

[0041] A sliding hole 43 is provided on one side of the base 4 away from the first slide groove 41, and the sliding hole 43 is connected to the second slide groove 42, and the reset block 72 passes through the sliding hole 43 and is fixedly connected to the connecting block. By setting the sliding hole 43 and the reset block 72, the gravity unlocking structure can be reused. When the fire is over, the reset block 72 is moved upward along the sliding hole 43 to drive the U-shaped gravity block 71 to move upward, and then a new temperature-sensitive glass bead 9 is installed, which does not affect the use of the window and can also be used for the next fire. The above structure is simple to operate and can be recycled, which can save costs.

[0042] Furthermore, one end of the plug-in column 62 away from the elastic member 63 is in an arc shape, so that the plug-in column 62 can be quickly squeezed and retracted when the moving block moves downward.

[0043] As an example, the base 4 is provided with a receiving groove 45 corresponding to the temperature-sensitive glass bead 9, the receiving groove 45 is respectively connected with the second slide groove 42 and the outside, and the temperature-sensitive glass bead 9 is placed in the receiving groove 45. By providing the receiving groove 45, on the one hand, the temperature-sensitive glass bead 9 can contact with the outside world and sensitively sense the outside temperature, and on the other hand, it is convenient to install and replace the temperature-sensitive glass bead 9.

[0044] As an example, a stepped hole 44 is further provided on the side of the base 4 away from the first slide groove 41, and the stepped hole 44 is opposite to the plug-in hole, and an elastic pressing block 8 is provided in the stepped hole 44; a through hole 711 for the elastic pressing block 8 to pass through is provided at a position of the connection block corresponding to the elastic pressing block 8; the length of the elastic pressing block 8 is greater than the distance between the plug-in hole and the outer end surface of the stepped hole 44. By providing the elastic pressing block 8, the movable window can be pressed in a normal use state, and the elastic pressing block 8 can pass through the through hole 711, the second slide groove 42, the plug-in hole and abut against the plug-in column 62 in sequence, and the plug-in column 62 can be retracted into the first slide groove 41 by continuing to press, so that it is unlocked, and the movable window can be manually closed at this time.

[0045] Specifically, the elastic pressing block 8 includes a stepped block 81 and a spring 82, the stepped block 81 is placed in the stepped hole 44, the large diameter portion of the stepped block 81 is close to the plug hole, one end of the small diameter portion of the stepped block 81 is connected to an outer protrusion 83, and the spring 82 is sleeved on the outside of the small diameter portion and abuts between the large diameter portion and the protrusion. Through the above structure, the elastic pressing block 8 can be limited in the stepped hole 44 and will not be separated from the base 4 when not in use.

[0046] As an example, the first heat-insulating fireproof glass 12 and the second heat-insulating fireproof glass 22 are both formed by interlacing glass and crystalline silicon, wherein the outermost layers of the first heat-insulating fireproof glass 12 and the second heat-insulating fireproof glass 22 are glass. By interlacing glass and crystalline silicon to form a highly transparent and hard heat-insulating fireproof glass, it has high strength, high heat resistance and fire resistance, and can improve the fireproof and heat-insulating performance of the fireproof window of the present application.

[0047] As an example, the thickness of the glass and the crystalline silicon are both 5 mm, and the thickness of the first heat-insulating fireproof glass 12 and the second heat-insulating fireproof glass 22 are both 35 mm, so that the fireproof window achieves high transparency while having high strength and high fireproof performance.
