Description

Technical Field

[0001] This utility model relates to the field of fire-resistant roller shutter doors for building safety, and more specifically, to a fire-resistant roller shutter door assembly based on building safety. Background Technology

[0002] Fire-resistant roller shutters are retractable isolation devices made of fire-resistant materials such as metal. They are typically installed in building corridors, stairwells, or at the boundaries of functional areas, primarily to block the spread of fire and smoke during a fire. Their core function is to automatically and rapidly descend through temperature and smoke detection systems or fire alarm signals, forming a physical barrier that effectively delays the spread of fire for 2-4 hours, buying crucial time for evacuation and fire rescue. Fire-resistant roller shutters significantly reduce the horizontal and vertical penetration of high-temperature smoke inside buildings, preventing the "chimney effect" from exacerbating the disaster and reducing the contamination of toxic gases in evacuation routes.

[0003] In open spaces such as large shopping malls, underground parking garages, factories, and warehouses, fire-resistant roller shutters can divide fire zones, meeting daily passage needs while cutting off air circulation and heat transfer paths in emergency situations. Combined with sprinkler systems, they form a three-dimensional fire protection system, significantly improving the passive fire resistance of building structures. They are an indispensable compliant safety facility in modern building fire protection design.

[0004] In the event of a fire, the spread of the fire may damage the electrical wiring, which could lead to a power outage and affect the normal opening and closing of the fireproof roller shutter door driven by the motor. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies: during a fire, the spread of fire may damage the wiring, which in turn will cause a power outage, affecting the normal opening and closing of the fireproof roller shutter door driven by the motor. Therefore, this utility model proposes a fireproof roller shutter door assembly based on building safety.

[0006] The specific technical solution is as follows: A fireproof roller shutter assembly based on building safety includes an outer positioning frame and a fireproof roller shutter. The outer positioning frame is installed on the door frame of the building. The fireproof roller shutter is assembled inside the outer positioning frame and can move along the main body of the outer positioning frame for folding and unfolding. The fireproof roller shutter includes a traction rope and multiple unit fireproof roller shutters distributed along the traction rope array. The multiple unit fireproof roller shutters are rotatably connected, and both ends of the multiple unit fireproof roller shutters are slidably assembled on the outer positioning frame. The traction rope is connected to the top of the outer positioning frame and is limited by an electrical limiting structure inside the outer positioning frame. Each unit fireproof roller shutter includes a fireproof plate one and a fireproof plate two, and an elastic connector for the elastic rotatable connection of the fireproof plate one and the fireproof plate two. Therefore, after a power outage during a fire, the electrical limiting structure loses its restraint on the traction rope, and the traction rope loses its restraint on the multiple fireproof roller shutters distributed along the traction rope array. The elastic connectors between fireproof plate one and fireproof plate two on the unit fireproof roller shutter will elastically unfold and unfold the fireproof roller shutter through the unit fireproof roller shutter, realizing the automatic closure of the fireproof roller shutter after the power is cut off. By dividing fire compartments through fireproof roller shutters, daily passage needs can be met, and in an emergency, the air circulation and heat transfer paths of the three elements of combustion can be cut off. Combined with the sprinkler system, a three-dimensional fire protection system is formed, which significantly improves the passive fire protection capability of the building structure.

[0007] In the technical solution of this utility model, both the fireproof board one and the fireproof board two are made of fireproof and heat-insulating materials.

[0008] In the technical solution of this utility model, the outer positioning frame includes a winding drum, which is rotatably equipped with a take-up roller, and a take-up rod is used to wind a take-up traction rope; an electrical limiting structure is installed inside the winding drum and acts on the take-up rod.

[0009] Furthermore, a power drive wheel is fixed at one end of the storage roller. The power drive wheel is used to rotate by a drive motor or a pull rope to achieve folding and storage of the fireproof roller shutter.

[0010] Furthermore, the electrical limiting structure includes a magnetic adsorption disk A and a magnetic adsorption disk B, with magnetic adsorption disk A installed on the take-up roller and magnetic adsorption disk B installed inside the take-up drum.

[0011] Both magnetic adsorption disk A and magnetic adsorption disk B have electromagnetic coils inside. By switching the electromagnetic coils on and off, magnetic adsorption disk A and magnetic adsorption disk B can be made to have or lose their magnetism.

[0012] Therefore, after a power outage due to a fire, the electromagnetic coils inside both magnetic adsorption discs A and B will lose their magnetism, and they will no longer attract each other. The take-up roller will be released from its restraints inside the take-up drum and can rotate freely. This means the electrical restraint structure will lose its restraint on the traction rope, and the traction rope will lose its restraint on the multiple fireproof roller shutters distributed along the traction rope array. The elastic connectors between fireproof plate one and fireproof plate two on each fireproof roller shutter will elastically unfold and unfold the fireproof roller shutter through the unit fireproof roller shutter, thus achieving automatic closing of the fireproof roller shutter after a power outage.

[0013] Furthermore, the outer positioning frame also includes two side guide rails, which are distributed in parallel and located at the ends of the winding drum; the side guide rails are integrally fixed to the winding drum.

[0014] In the technical solution of this utility model, the elastic connector includes a connecting column, which is mounted on an outer positioning frame; a guide slider is fixed at each end of the connecting column, and the guide slider is slidably assembled on the outer positioning frame.

[0015] Specifically, the connecting column is parallel to the winding drum and is mounted between two side guide rails. The connecting column is slidably mounted on the side guide rails via a guide slider. The side guide rails are provided with grooves to cooperate with the guide slider. The grooves are provided with limiting flanges to limit the guide slider and prevent the guide slider from falling out of the grooves.

[0016] Furthermore, the elastic connector also includes multiple elastic bodies, each of which is sleeved and fixed on the connecting post; the multiple elastic bodies are distributed at equal intervals along the connecting post; the elastic bodies are used to act on fireproof board one and fireproof board two, for the elastic rotational connection of fireproof board one and fireproof board two.

[0017] The elastic body includes a spring, which is sleeved and fixed on the connecting column; the elastic body also includes a support column one and a support column two, which are distributed at both ends of the spring; the support column one and the support column two are integrally fixed to the spring; the support column one is inserted and fixed on the fireproof board one, and the support column two is inserted and fixed on the fireproof board two.

[0018] Compared with existing technologies, this utility model, based on building safety, features a fire-resistant roller shutter assembly. In the event of a fire and power outage, the electrical limiting structure loses its restraint on the traction rope, causing the traction rope to lose its restraint on multiple fire-resistant roller shutter units distributed along the traction rope array. The elastic connector between fire-resistant plate one and fire-resistant plate two on each fire-resistant roller shutter will elastically unfold, and the fire-resistant roller shutter will be opened through the unit fire-resistant roller shutter, achieving automatic closure of the fire-resistant roller shutter after power failure. By dividing fire zones through the fire-resistant roller shutter, it not only meets daily passage needs but also cuts off the airflow and heat transfer paths of the three elements of combustion in an emergency. Combined with the sprinkler system, it forms a three-dimensional fire protection system, significantly improving the passive fire resistance of the building structure. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.

[0030] like Figure 1 , Figure 2 , Figures 4-6 As shown: A fireproof roller shutter door assembly based on building safety includes an outer positioning frame 1 and a fireproof roller shutter 2, wherein the outer positioning frame 1 is installed on the door frame of the building;

[0031] The method of "installing the external positioning frame 1 on the door frame of the building" is existing technology. For example, it can be installed by bolts or by building expansion nails, etc. The specific structure is not limited, as long as the external positioning frame 1 can be stably installed on the door frame of the building. At the same time, it can be purchased directly on the market, and there are relevant descriptions in relevant journal literature. It is not what this invention is trying to protect, so it will not be described in detail here.

[0032] The fireproof roller shutter 2 is assembled inside the outer positioning frame 1 and can move along the main body of the outer positioning frame 1 for folding and unfolding.

[0033] The fireproof roller shutter 2 includes a traction rope 21 and multiple unit fireproof roller shutters 22 arranged in an array along the traction rope 21; the multiple unit fireproof roller shutters 22 are rotatably connected to each other, and both ends of the multiple unit fireproof roller shutters 22 are slidably mounted on the outer positioning frame 1; the traction rope 21 is connected to the top of the outer positioning frame 1 and is limited by the electrical limiting structure inside the outer positioning frame 1.

[0034] The method of "rotating connection between multiple fireproof roller shutters 22" is existing technology. For example, it can be a rotating connection through a pivot or a rotating connection through a fixed column, etc. The specific structure is not limited, as long as it can satisfy the requirement that the fireproof roller shutter 2 can move along the main body of the outer positioning frame 1 through multiple fireproof roller shutters 22 for folding and unfolding. At the same time, it can be purchased directly on the market, and there are relevant descriptions in relevant journal literature. It is not what this invention is trying to protect, and will not be described in detail here.

[0035] The unit fireproof roller shutter 22 includes a fireproof plate 1 23 and a fireproof plate 25, as well as an elastic connector 24 for the elastic rotational connection of the fireproof plate 1 23 and the fireproof plate 25.

[0036] Therefore, after a power outage due to a fire, the electrical limiting structure loses its restraint on the traction rope 21, and the traction rope 21 loses its restraint on the multiple fireproof roller shutters 22 distributed along the array of traction ropes 21; the elastic connector 24 between the fireproof plate 1 23 and the fireproof plate 25 on the unit fireproof roller shutter 22 will elastically unfold and unfold the fireproof roller shutter 2 through the unit fireproof roller shutter 22, realizing the automatic closing of the fireproof roller shutter 2 after the power is cut off; by dividing fire compartments through the fireproof roller shutter 2, it not only meets the daily passage needs, but also cuts off the air circulation and heat transfer path of the three elements of combustion in an emergency, and forms a three-dimensional fire protection system in conjunction with the sprinkler system, significantly improving the passive fire protection capability of the building structure.

[0037] In the technical solution of this utility model, such as Figure 5 As shown: Both fireproof board 23 and fireproof board 25 are made of fireproof and heat-insulating materials.

[0038] Fireproof and heat-insulating materials are existing technologies, and their detailed structures can be found in existing literature and journals, as well as being readily available on the market; they are not the subject of this invention, and will not be described in detail here, nor are they shown in the accompanying drawings.

[0039] In the technical solution of this utility model, such as Figure 3 As shown: The outer positioning frame 1 includes a winding drum 11, which is rotatably equipped with a take-up roller. The take-up roller is used to wind the take-up traction rope 21. An electrical limiting structure is installed inside the winding drum 11 and acts on the take-up roller.

[0040] The method of "rotating assembly of the storage roller" is existing technology. For example, it can be assembled by rotating a shaft or by rotating a fixed column, etc. The specific structure is not limited, as long as it can satisfy the requirement that the storage roller is rotated and assembled inside the winding drum 11. At the same time, it can be purchased directly on the market, and there are relevant descriptions in relevant journal literature. It is not what this invention is trying to protect, so it will not be described in detail here.

[0041] Furthermore, a power drive wheel is fixed at one end of the storage roller. The power drive wheel is used to rotate by a drive motor or a pull rope to achieve the folding and storage of the fireproof roller shutter 2.

[0042] Furthermore, the electrical limiting structure includes a magnetic adsorption disk A and a magnetic adsorption disk B, with magnetic adsorption disk A installed on the take-up roller and magnetic adsorption disk B installed inside the take-up drum 11.

[0043] Both magnetic adsorption disk A and magnetic adsorption disk B have electromagnetic coils inside. By switching the electromagnetic coils on and off, magnetic adsorption disk A and magnetic adsorption disk B can be made to have or lose their magnetism.

[0044] Therefore, after a power outage due to a fire, the electromagnetic coils inside both magnetic adsorption disks A and B will lose their magnetism, and they will no longer attract each other. The take-up roller will be released from its restraint inside the take-up drum 11 and can rotate freely. This means that the electrical restraint structure loses its restraint on the traction rope 21, and the traction rope 21 loses its restraint on the multiple fireproof roller shutters 22 distributed along the array of traction ropes 21. The elastic connector 24 between the fireproof plate 1 23 and the fireproof plate 25 on the fireproof roller shutter 22 will elastically unfold and unfold the fireproof roller shutter 2 through the fireproof roller shutter 22, thus achieving automatic closing of the fireproof roller shutter 2 after a power outage.

[0045] Furthermore, such as Figure 3 As shown: The outer positioning frame 1 also includes two side guide rails 12, which are distributed in parallel and located at the ends of the winding drum 11; the side guide rails 12 are integrally fixed with the winding drum 11.

[0046] In the technical solution of this utility model, such as Figures 5-8 As shown: The elastic connector 24 includes a connecting post 241, which is mounted on the outer positioning frame 1; a guide slider is fixed at each end of the connecting post 241, and the guide slider is slidably assembled on the outer positioning frame 1.

[0047] Specifically, the connecting post 241 is parallel to the winding drum 11 and is mounted between two side guide rails 12. The connecting post 241 is slidably mounted on the side guide rails 12 via a guide slider. The side guide rails 12 are provided with a groove to cooperate with the guide slider. A limiting flange is provided on the groove to cooperate with the guide slider. The limiting flange is used to limit the guide slider and prevent the guide slider from falling out of the groove.

[0048] Furthermore, such as Figures 5-8 As shown: The elastic connector 24 also includes a plurality of elastic bodies 242, which are all sleeved and fixed on the connecting post 241; the plurality of elastic bodies 242 are distributed at equal intervals along the connecting post 241; the elastic bodies 242 are used to act on the fireproof plate 1 23 and the fireproof plate 25, and are used for the elastic rotational connection of the fireproof plate 1 23 and the fireproof plate 25.

[0049] like Figures 6-8 As shown: The elastic body 242 includes a spring 2421, which is sleeved and fixed on the connecting post 241;

[0050] The elastic body 242 also includes a first support column 2422 and a second support column 2423, which are distributed at both ends of the spring 2421. The first support column 2422 and the second support column 2423 are directly fixed to the spring 2421 in an integral manner. The first support column 2422 is inserted and fixed to the first fireproof plate 23, and the second support column 2423 is inserted and fixed to the second fireproof plate 25.

[0051] After a power outage due to a fire, the electrical limiting structure loses its limiting effect on the traction rope 21, and the traction rope 21 loses its limiting effect on the multiple fireproof roller shutters 22 distributed along the array of traction ropes 21; the elastic connector 24 between the fireproof plate 1 23 and the fireproof plate 25 on the unit fireproof roller shutter 22 will elastically unfold through the spring 2421, and unfold the fireproof roller shutter 2 through the unit fireproof roller shutter 22, realizing the automatic closing of the fireproof roller shutter 2 after the power is cut off.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
