Description

Technical Field

[0001] The utility model relates to the technical field of super high-rise construction, in particular to an external frame dense mesh device for super high-rise buildings which can be automatically retracted and extended on windy days. Background Art

[0002] External scaffolding is a commonly used protective system in current construction projects and is an indispensable component of construction. Using external scaffolding in conjunction with fine mesh netting not only ensures edge protection during elevated work, but also prevents impact from falling materials within the building. Ultimately, it also contributes to a more civilized construction site and enhances its image.

[0003] Currently, the most common method of securing steel tubular scaffolding is a combination of fine mesh netting. When using fine mesh netting, workers often secure it to the scaffolding steel tubes with ties. This method is currently used on the vast majority of construction sites. However, this method of securing also presents potential risks. High winds are common in the summer, and their occurrences are random. Excessive wind loads acting on the scaffolding with fine mesh netting can cause the scaffolding to tip over or even collapse. Furthermore, it is risky for workers to untie the ties and retract the netting during strong winds, or to do so late at night when no one is available.

[0004] Therefore, how to ensure the wind resistance of external scaffolding, especially high-rise external scaffolding construction, is one of the key tasks for those skilled in the art. Utility Model Content

[0005] The utility model aims to provide an external scaffolding fine mesh device which can be automatically retracted and extended on windy days for super high-rise buildings. When the external wind force reaches a certain level, the fine mesh is automatically retracted, thereby improving the wind resistance of the external scaffolding.

[0006] In order to solve the above technical problems, an embodiment of the present utility model provides an external frame dense mesh device that can be automatically retracted and extended on super-high-rise windy days, including a wind pressure plate, a guide rod, a trigger and a reel motor. The wind pressure plate is connected to the trigger through the guide rod. After the external wind pressure is greater than or equal to the threshold wind pressure, the trigger is triggered by driving the guide rod, controlling the reel motor to rotate in the opposite direction, and retracting the dense mesh connected to the reel motor.

[0007] The utility model further includes a top sensor connected to the reel motor, which is used to control the reel motor to stop working after detecting that the dense mesh reaches the top.

[0008] In which, the trigger includes a trigger body and an elastic trigger component arranged between the wind pressure plate and the trigger body, the guide rod is a guide rod having positive and negative poles of a battery, and after the wind pressure plate is subjected to wind pressure greater than or equal to the threshold wind pressure, the deformation of the elastic trigger component is greater than or equal to the threshold deformation, so that the guide rod reaches the specified position, and the roller motor is activated through the positive and negative poles of the battery, so that the roller motor works.

[0009] Wherein, the elastic trigger component is a spring stretching trigger component or a spring pressing piece.

[0010] It also includes a cross bar, a stainless steel bracket and a connecting fastener. The scroll motor is fixed to the stainless steel bracket through the connecting fastener, and the cross bar is set through the stainless steel bracket, and is installed in a designated position through the cross bar.

[0011] It also includes a metal card slot, a bottom sensor arranged in the metal card slot, and a chamfered metal clip arranged on the metal card plate at the bottom of the dense mesh.

[0012] It also includes a turntable for installing the trigger and a baffle arranged on the turntable, the connecting end of the baffle and the turntable and the connecting end of the trigger and the turntable are on the diameter of the circumference of the turntable, so that after the trigger is triggered, the baffle moves in the opposite direction of the trigger, so that the movable end of the baffle moves out of the chamfered metal buckle to release the metal clip, or after the external wind pressure is lower than the threshold wind pressure for a predetermined period of time, the metal clip enters the metal slot and the movable end of the baffle enters the chamfered metal buckle.

[0013] Wherein, the top sensor and the bottom sensor are infrared sensors or gravity sensors.

[0014] Wherein, it also includes a display connected to the wind pressure plate and the scroll motor, which is used to display the pressure status of the wind pressure plate and the operating status of the scroll motor.

[0015] It also includes a battery and a solar panel connected to the reel motor. The solar panel is used to charge the battery and supply power to the reel motor through the battery.

[0016] The ultra-high-rise high-windy day automatically retractable outer frame dense mesh device provided by the embodiment of the utility model has the following advantages compared with the prior art:

[0017] The super-high-rise structure's automatically retractable mesh netting device uses a wind pressure plate to detect wind pressure. When the external wind pressure is greater than or equal to a threshold wind pressure for a predetermined period of time, it indicates that the current wind force has reached a point where the mesh netting needs to be rolled up. Simultaneously, the wind pressure plate drives the guide rod to trigger the trigger, which in turn controls the reel motor to rotate in the opposite direction, retracting the mesh netting connected to the reel motor. This automatically retracts the mesh netting when the external wind force reaches a certain level, improving the stability and reliability of the entire structure and the wind resistance of the external scaffolding without requiring manual operation.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please refer to Figure 1-Figure 3 , Figure 1A schematic structural diagram of an embodiment of an external frame dense mesh device for a super high-rise building that can be automatically retracted and extended on windy days provided by the utility model; Figure 2 A schematic diagram of the top structure of an embodiment of an external frame dense mesh device for a super-high-rise building that can be automatically retracted and extended on windy days provided by an embodiment of the utility model; Figure 3 This is a schematic diagram of the bottom structure of an embodiment of an external frame dense mesh device for super high-rise buildings that can be automatically retracted and extended on windy days provided by an embodiment of the utility model.

[0025] In one embodiment, the super-high-rise structure's external mesh netting device that can be automatically retracted and extended during high winds includes a wind pressure plate 10, a guide rod 20, a trigger 21, and a reel motor 30. The wind pressure plate 10 is connected to the trigger 21 via the guide rod 20. When the external wind pressure is greater than or equal to a threshold wind pressure, the guide rod 20 is driven to trigger the trigger 21, thereby controlling the reel motor 30 to rotate in the opposite direction, thereby retracting the mesh net 90 connected to the reel motor 30.

[0026] The wind pressure is detected by using the wind pressure plate 10. When the external wind pressure is greater than or equal to the threshold wind pressure, it indicates that the current wind force has reached the point where the mesh net 90 needs to be rolled up. At the same time, the wind pressure plate 10 drives the guide rod 20 to trigger the trigger 21, and finally controls the reel motor 30 to rotate in the reverse direction to retract the mesh net 90 connected to the reel motor. When the external wind force reaches a certain level, the mesh net is automatically retracted, thereby improving the stability and reliability of the entire structure and the wind resistance of the external scaffolding without manual operation.

[0027] In this application, the mesh screen is collected by the reel motor 30, but the specific collection process may still require manual operation to prevent the mesh screen from continuing to rotate after collection, resulting in idling, or even causing the counterweight set at the bottom of the mesh screen to damage the reel motor 30 or the corresponding retracting device.

[0028] To solve this technical problem, in one embodiment, the external frame dense mesh device that can be automatically retracted and extended on windy days in super-high-rise buildings also includes a top sensor 40 connected to the reel motor 30, which is used to control the reel motor 30 to stop working after detecting that the dense mesh 90 reaches the top.

[0029] After the top sensor 40 detects that the dense mesh 90 reaches the top, the reel motor 30 is controlled to stop working, so that the reel motor 30 automatically stops working after the dense mesh 90 is collected, thereby improving the automation control of the entire device and improving the control efficiency.

[0030] The present application does not limit the top sensor 40. It can be mechanically implemented, such as by placing a metal component on the dense mesh 90 and utilizing the magnetic force of a magnet. When the metal component reaches a predetermined position, the magnet attracts the metal component. The reaction force pulls the magnet outward, disconnecting the circuit of the corresponding reel motor 30, stopping the power supply, and causing it to stop working. Alternatively, a photoelectric sensor can be used. When the metal component passes through, no photoelectric signal is detected, thereby controlling the reel motor 30 to stop operating.

[0031] In addition to using the above-mentioned top sensor 40, a timer or the like may be used alone or in combination to control the state of the scroll motor 30, and this application does not limit this.

[0032] The present application does not limit the structure and triggering method of the trigger 21, but in order to simplify the structure and avoid false triggering caused by a sudden short-term strong wind from the outside, or when a timer is needed for immediate operation after the trigger is completed, in one embodiment,

[0033] The trigger 21 includes a trigger body and an elastic trigger component arranged between the wind pressure plate 10 and the trigger body. The guide rod 20 is a guide rod having positive and negative poles of a battery. After the wind pressure plate 10 is subjected to a wind pressure greater than or equal to the threshold wind pressure, the deformation of the elastic trigger component is greater than or equal to the threshold deformation, so that the guide rod 20 reaches the specified position, and the roller motor 20 is activated through the positive and negative poles of the battery, so that the roller motor 30 works.

[0034] The elastic trigger component can avoid misoperation caused by sudden strong winds. Instead, the external wind energy reaches a certain level within a certain period of time, thereby turning on the scroll motor 30 without setting components such as a timer, making the entire trigger component structure simple.

[0035] In addition, the elastic trigger component only needs to receive a certain amount of energy. If a timing method is used directly, there will be a certain error. For example, if the trigger starts at level 8 or above, if the wind speed increases, the timer will not be reduced. According to common sense, it needs to be started earlier. If a processor is used for calculation, the amount of calculation will be large and the equipment cost will increase.

[0036] The elastic trigger component is used, which will be automatically triggered as long as the external wind energy reaches a certain level. It has a simple structure and does not require data processing and timely operation. It can start the reel and roll up the dense mesh 90 in time.

[0037] The present application does not limit the structure and installation method of the elastic trigger component, and the elastic trigger component is a spring tension trigger component or a spring pressure piece.

[0038] That is, the elastic triggering member in the present application can be triggered by stretching, that is, when the wind pressure plate 10 is pushed, the movable end moves away from the wind pressure plate 10, while the spring pressure piece can be triggered by one end approaching the wind pressure plate 10 during the push of the pressure divider plate, and is triggered by deformation under pressure.

[0039] It should be noted that the present application includes but is not limited to the above-mentioned structure.

[0040] The present application does not limit the installation method of the reel motor 30 and the like.

[0041] In one embodiment, in order to facilitate installation and improve installation efficiency and convenience, in one embodiment, the super-high-rise external frame dense mesh 90 device that can be automatically retracted and extended on windy days also includes a cross bar 50, a stainless steel bracket and a connecting fastener. The roller motor 30 fixes the stainless steel bracket through the connecting fastener, and sets the cross bar 50 through the stainless steel bracket, and is installed in a designated position through the cross bar 50.

[0042] The installation position of the entire structure is determined by the cross bar 50. The installation position and installation object can be determined according to different needs, and then the scroll motor 30 is installed on the cross bar 50 through a stainless steel bracket and connecting fasteners. The structure is simple.

[0043] This application includes but is not limited to the above-mentioned installation methods.

[0044] The present application mainly realizes the folding of the dense mesh net 90. However, in actual operation, it is not only necessary to determine the end of folding, but also to control the corresponding timing in the subsequent release. Moreover, the dense mesh net 90 itself is relatively light and easily blown up.

[0045] Therefore, in one embodiment, in order to realize the termination of automatic folding and releasing, and to realize the position detection of the dense mesh 90, the external frame dense mesh 90 device that can be automatically folded and released on windy days in super high-rise buildings also includes a metal card slot 80, a bottom sensor 23 arranged in the metal card slot 80, and a chamfered metal buckle arranged on the metal card plate at the bottom of the dense mesh 90.

[0046] By providing the metal slot 80 and the angled metal buckle, automatic control can be achieved, and automatic control can be achieved by detecting the position of the chamfered metal buckle.

[0047] The present application includes but is not limited to the metal slot 80 and the angled metal buckle, and other structures can also be used.

[0048] In order to realize the automatic release of the dense mesh 90, in one embodiment, the external frame dense mesh 90 device that can be automatically retracted and extended on windy days in super high-rise buildings also includes a turntable for installing the trigger 21 and a baffle 22 arranged on the turntable, and the connection end of the baffle 22 and the turntable and the connection end of the trigger 21 and the turntable are on the diameter of the circumference of the turntable, so that after the trigger 21 is triggered, the baffle 22 moves in the opposite direction of the trigger 21, so that the movable end of the baffle 22 moves out from the chamfered metal buckle to release the metal clip, or after the external wind pressure is lower than the threshold wind pressure for a predetermined period of time, the metal clip enters the metal slot 80, and the movable end of the baffle 22 enters the chamfered metal buckle.

[0049] By providing a turntable and a baffle 22 and changing the position of the movable end of the baffle 22 and the chamfered metal buckle, that is, clamping or releasing, the efficiency and reliability of the use of the dense mesh 90 are improved.

[0050] The present application includes but is not limited to the above structures.

[0051] The present application detects the position of the dense mesh 90 through the top sensor 40 and the bottom sensor 23, and does not limit the structure thereof. The top sensing device 40 and the bottom sensor 23 are infrared sensors or gravity sensors.

[0052] The present application includes but is not limited to the use of the above-mentioned bottom sensor 23 .

[0053] In order to further achieve efficient management, in one embodiment, the external mesh net 90 device that can be automatically retracted and extended on windy days in super-high-rise buildings also includes a display connected to the wind pressure plate 10 and the roller motor 30, which is used to display the pressure status of the wind pressure plate 10 and the operating status of the roller motor 30.

[0054] In an embodiment of the present application, one or more of the above-mentioned devices can be set up in a building. For example, only one of the above-mentioned structures needs to be used to control multiple dense meshes 90, and synchronous automatic control can be used to control the other dense meshes 90, thereby improving the control efficiency. It is sufficient to set up one of the above-mentioned devices in the same direction, and set up one of the above-mentioned devices in each direction of the building for wind force detection.

[0055] Furthermore, since the mains electricity can be used for driving during the construction process, the connection of the wires is relatively complicated during the implementation process. For example, in many floors, the wires are usually installed at the end.

[0056] Therefore, in order to reduce the installation of wires, and because the dense mesh net 90 is lighter in weight and requires less electricity, in one embodiment, the external frame dense mesh net 90 device that can be automatically retracted and extended on windy days also includes a battery 60 connected to the roller motor 30 and a solar panel 70, and the solar panel 70 is used to charge the battery 60 and power the roller motor 30 through the battery 60.

[0057] The storage battery 60 and the solar panel 70 can realize automatic power supply, reduce the installation of the external wire structure, and improve the convenience and efficiency of power supply.

[0058] In one embodiment, the present application adopts the external frame dense mesh 90 device that can automatically retract and extend in windy days for the super high-rise building. The wind pressure plate 10 is connected to the guide rod 20. If the strong wind reaches level 8, the bottom wind pressure pushes the wind pressure plate 10, and the wind pressure plate 10 drives the guide rod 20 forward to push the spring pressure plate, so that the blocking rod 22 moves backward, thereby releasing the metal clamping plate. At this time, after the top device is subjected to wind pressure, the wind pressure plate 10 drives the guide rod 20 containing the positive and negative poles of the battery. After connecting to the solar cell, it starts to power on, connects to the reel motor 30, reverses, and retracts the dense mesh 90. When it reaches the position of the top sensing device 40, the power is cut off and stopped. After the strong wind passes, the top device. The wind pressure plate 10 is retracted, the motor rotates forward, and the dense mesh 90 is lowered. After the metal clamping plate reaches the lower sensing device and enters the buckle slot, the upper motor cuts off and stops after 3 seconds. A windshield and power supply system are set on each surface, and the rest are retracted and extended at the same time through sensors.

[0059] The technical solution in this application solves the problem of excessive wind loads on super-high-rise external scaffolding during strong winds, which can cause the scaffold to overturn or even collapse. On the one hand, the scaffold can be automatically retracted on windy days, significantly reducing the impact of wind loads on the scaffold. On the other hand, it saves labor and avoids the risks of workers working on windy days, ultimately ensuring that the scaffold can be operated without workers.

[0060] The above device is convenient for workers to construct, has a firm fixation, improves efficiency, shortens construction period, is easy to replace and disassemble, makes up for the situation where no one is working during the workers' idle period, avoids the safety hazards caused by workers dismantling and collecting the 90-mesh net on windy days, reduces material loss and waste, is recyclable, green and environmentally friendly, and can be circulated to other construction sites for use.

[0061] In summary, the embodiment of the present application provides an external mesh netting device for super-high-rise buildings that can automatically retract and extend during strong winds. This device detects wind pressure using a wind pressure plate. When the external wind pressure is greater than or equal to a threshold wind pressure, it indicates that the current wind force has reached a point where the mesh netting needs to be rolled up. Simultaneously, the wind pressure plate drives the guide rod to trigger the trigger, which in turn controls the reel motor to rotate in the opposite direction, retracting the mesh netting connected to the reel motor. This automatically retracts the mesh netting when the external wind force reaches a certain level, improving the stability and reliability of the entire structure and the wind resistance of the external scaffolding without the need for manual operation.

This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
