Description

Technical Field

[0001] The present application relates to the technical field of fireproof roller shutters, and in particular to special-shaped fireproof roller shutters at atrium openings of commercial complexes. Background Art

[0002] Fireproof roller shutters are fire-proof isolation facilities used inside or outside buildings. Fireproof roller shutters are usually made of special high-temperature resistant and fire-resistant materials. When a fire occurs, the fireproof roller shutters close to form a barrier, reducing the spread of flames and smoke to other areas. Fireproof roller shutters play a role in reducing the spread of fire and controlling the spread of fire, thereby protecting people's lives and reducing property losses.

[0003] Commercial complexes gather many people. Therefore, when a fire occurs, fire shutters can be installed at the entrances of commercial complexes to form temporary fire barriers to prevent the spread of fire and smoke. This partition helps to protect the safe evacuation of personnel, and also provides valuable time for the fire department to extinguish the fire. Fire shutters can be used as part of the evacuation route to guide people to evacuate from dangerous areas. Especially in the atrium area, people may gather because of its openness. The correct use of fire shutters can ensure that people can evacuate quickly in an emergency.

[0004] The fireproof roller shutter includes a rotating shaft and a rolling surface. The rotating shaft is rotated to reel the rolling surface up or release it to lower it. The rotating shaft is a linear axis. When the atrium opening of the commercial complex is irregular, it is difficult to set the fireproof roller shutter according to the shape of the atrium opening of the commercial complex. Summary of the invention

[0005] In order to improve the adaptability of fireproof roller shutters to atrium openings of commercial complexes with different shapes, the present application provides special-shaped fireproof roller shutters for atrium openings of commercial complexes.

[0006] The special-shaped fireproof roller shutter for the atrium opening of the commercial complex provided in this application adopts the following technical solution:

[0007] A special-shaped fireproof roller shutter for an atrium opening of a commercial complex comprises a roller shutter, wherein the roller shutter comprises a rolling surface and a driving mechanism, wherein the driving mechanism is used to drive the rolling surface to be rolled up or unfolded, a folding curtain is arranged on one side of the roller shutter, wherein the folding curtain comprises a folding surface and a transmission mechanism, wherein one side of the folding surface is inserted into a roller shutter cavity, wherein the transmission mechanism is used to drive the folding surface to be folded or unfolded, an outer base frame is arranged at the bottom of the roller surface, an inner base frame is arranged at the bottom of the folding surface, and decorative panels are respectively fixed to the bottom of the inner base frame and the bottom of the outer base frame.

[0008] By adopting the above technical solution, one side of the folding curtain is inserted into the rolling curtain cavity. When a fire occurs, the fire is reduced from the gap between the folding curtain and the rolling curtain. The rolling curtain and the folding curtain are installed in combination for use. When the atrium opening of the commercial complex is irregular, the folding curtain will be used in the place with the curve. The folding curtain can be folded according to the shape of the curve, so that the folding curtain adapts to the shape of the curve. Under the action of the folding curtain, the adaptability of the fireproof rolling curtain to the atrium openings of the commercial complex with different shapes can be improved.

[0009] Under the action of the outer base frame and the inner base frame, the weight of the bottom of the rolling shutter and the folding shutter can be increased, thereby accelerating the descending speed of the rolling surface and the folding surface, and the strength of the rolling shutter and the folding shutter can be improved, thereby improving the ability of the rolling shutter and the folding curtain to resist the fire pressure, so as to reduce the situation where the rolling surface and the folding surface are exposed to the wind pressure of the fire and cause fire or be lifted up.

[0010] Under the action of the decorative panel, the weight of the bottom of the rolled surface and the folded surface can be further increased, thereby increasing the speed at which the folding curtains and the rolling curtains descend. Moreover, when the rolling curtains and the folding curtains are in a retracted state, the decorative panel can reduce the abruptness of the rolling curtains and the folding curtains in the surrounding ceiling. At the same time, it can also reduce the dust in the rolling curtains and the folding curtains from falling to the ground, thereby reducing the impact on consumers.

[0011] Preferably, the side walls of the folding surface are respectively fixed with pressure strips, and a guide component is provided on the outer side of the pressure strip, and the guide component includes a guide part, and the side wall of the guide part is in contact with the outer side of the roll surface.

[0012] By adopting the above technical solution, the side wall of the guide part abuts against the outer side of the roll surface. When the folding surface moves vertically along the roll surface, the folding surface can be guided to move under the action of the guide part, so that the folding surface can better move along the corresponding trajectory. When a fire occurs, the shaking of the folding surface caused by the downward movement is reduced, and the movement of the folding surface is more stable.

[0013] Preferably, the guide assembly also includes a mounting column and a connecting portion, one side of the mounting column is connected to the outer wall of the pressure strip, a mounting groove is provided at the top of the mounting column near one end of the roll surface, one end of the connecting portion is inserted into the mounting groove, the connecting portion is rotatably connected to the mounting column, and the side wall of the guide portion is connected to one end of the connecting portion away from the mounting column.

[0014] By adopting the above technical solution, the connecting part is rotatably connected to the mounting column, and under the action of the mounting groove, the connecting part can be rotated upward. When the folding curtain is folded, when two adjacent guide parts are in contact, while the lower guide part continues to move upward, the lower guide part applies an upward force to the upper guide part, so that the upper connecting part rotates upward, thereby shortening the gap between the two adjacent guide parts, making the thickness of the folded folding curtain smaller, and further making the space occupied by the folded folding curtain smaller.

[0015] Preferably, the guide portion is an arc-shaped rod.

[0016] By adopting the above technical solution, compared with the case where the guide part is a straight rod, the guide part is an arc-shaped rod, which can increase the contact area with the roll surface, thereby better guiding. At the same time, it can also increase the lateral contact length and reduce the situation where the guide part slides out of the roll surface.

[0017] Preferably, the distance between the top surface of the guide portion and the folding surface is greater than the distance between the bottom surface of the guide portion and the folding surface.

[0018] By adopting the above technical solution, the distance between the top surface of the guide part and the folding surface is greater than the distance between the bottom surface of the guide part and the folding surface, so that when the folding curtain is folded, when two adjacent guide parts are in contact, the top end of the lower guide part can abut against the outer wall of the upper guide part, thereby shortening the gap between the two adjacent guide parts.

[0019] Preferably, a support frame is provided inside the pressure strip, and the support frame is arranged horizontally.

[0020] By adopting the above technical solution, under the action of the supporting frame, the strength of the folding curtain can be improved, thereby improving the ability of the folding surface to resist the air pressure in the fire scene, so as to reduce the situation where the folding surface jumps into fire or is lifted up due to the wind pressure in the fire scene.

[0021] Preferably, a connecting groove is provided on an outer side of one end of the inner bottom frame close to the outer bottom frame, and the outer bottom frame is inserted into the connecting groove.

[0022] By adopting the above technical solution, the outer chassis is inserted into the connecting groove, thereby reducing the gap between the inner chassis and the outer chassis, thereby reducing the situation where fire escapes from the gap between the inner chassis and the outer chassis.

[0023] Preferably, the outer side wall of the inner bottom frame and the outer side wall of the outer bottom frame are on the same horizontal plane.

[0024] By adopting the above technical solution, the outer wall of the inner base frame and the outer wall of the outer base frame are on the same horizontal plane, so that the width of the inner base frame is consistent with that of the outer base frame, thereby making the width of the decorative panel consistent. Therefore, the specifications of the decorative panel can be the same, reducing the situation of using decorative panels of different specifications. At the same time, when performing ceiling installation, the width of the reserved space for rolling curtains and folding curtains is consistent, thereby reducing the trouble of construction.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. One side of the folding curtain is inserted into the rolling curtain cavity. When a fire occurs, the fire is reduced from the gap between the folding curtain and the rolling curtain. The rolling curtain and the folding curtain are installed and used in combination. When the atrium opening of the commercial complex is irregular, the folding curtain will be used at the bend. The folding curtain can be folded according to the shape of the bend, so that the folding curtain can adapt to the shape of the bend. Under the action of the folding curtain, the adaptability of the fireproof rolling curtain to the atrium openings of commercial complexes of different shapes can be improved.

[0027] 2. The side wall of the guide part is in contact with the outer side of the roll surface. When the folding surface moves vertically along the roll surface, the guide part can guide the movement of the folding surface so that the folding surface can move better along the corresponding trajectory. When a fire occurs, the shaking of the folding surface caused by the downward movement is reduced, making the movement of the folding surface more stable. BRIEF DESCRIPTION OF THE DRAWINGS

When the folding surface 21 moves vertically along the roll surface 11, under the action of the guiding portion 33, the folding surface 21 can be guided to move, so that the folding surface 21 can better move along the corresponding trajectory. When a fire occurs, the shaking of the folding surface 21 when moving downward is reduced, so that the folding surface 21 moves more smoothly.

[0044] In the embodiment of the present application, the guide portion 33 is an arc-shaped rod, and the distance between the top surface of the guide portion 33 and the folding surface 21 is greater than the distance between the bottom surface of the guide portion 33 and the folding surface 21, so that when the folding curtain 2 is folded, when two adjacent guide portions 33 are in contact, the top end of the lower guide portion 33 can abut against the outer wall of the upper guide portion 33, thereby shortening the gap between the two adjacent guide portions 33, making the thickness of the folded folding curtain 2 smaller, and further making the space occupied by the folded folding curtain 2 smaller, and in the process of the lower guide portion 33 continuing to move upward, the lower guide portion 33 applies an upward force to the upper guide portion 33, so that the upper connecting portion 32 rotates upward, thereby further shortening the gap between the two adjacent guide portions 33.

[0045] Reference Figure 5A decorative panel 4 is fixed to the bottom of the inner bottom frame 23 and the bottom of the outer bottom frame 17 respectively.
