Background Art

[0002] Currently, the deformation monitoring of most formwork support vertical poles is carried out manually on-site using equipment such as plumb bobs, plumb lines, and total stations. Since the pipe fittings of most formwork supports are relatively dense, real-time measurement is not convenient, and there are also certain safety risks for personnel to walk inside the formwork support. Especially during the concrete pouring period, the safety risks for measurement personnel to walk inside the formwork support increase exponentially. Moreover, the manual on-site measurement method for monitoring the deformation of formwork support vertical poles also significantly increases the labor cost. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a deformation monitoring system for the vertical poles of a full hall formwork support with less manual participation, convenient inspection, and capable of sending signals for excessive deformation at any time.

[0004] The technical solution adopted to solve the above technical problem is: a deformation monitoring system for the vertical poles of a full hall formwork support, including each vertical pole body arranged inside the full hall formwork support. The deformation monitoring system further includes a monitoring base point and a real-time alarm device for the combined monitoring of the vertical pole deformation. The monitoring base point is arranged at the top of the vertical pole body at a specified position. During the working process of the full hall formwork support, the bending, inclination, and settlement deformation of the vertical pole body at the specified position are monitored by the real-time alarm device for the combined monitoring of the vertical pole deformation in cooperation with the monitoring base point, and an alarm signal is sent when the deformation exceeds the standard.

[0005] Furthermore, the monitoring base point is composed of a plastic-steel hanging bracket hoop-connected to the top of the vertical pole body, and the reference point monitored by the real-time alarm device for the combined monitoring of the vertical pole deformation is arranged at a specified position of the plastic-steel hanging bracket. During the working process of the full hall formwork support, the real-time alarm device for the combined monitoring of the vertical pole deformation monitors the bending, inclination, and settlement deformation of the vertical pole body by monitoring the position change of the specified reference point.

[0006] The preferred mode of the above solution is that the real-time alarm device for the combined monitoring of the vertical pole deformation includes an alarm component, a normally open circuit, and a deformation information transmission component. The alarm component is connected in series on the normally open circuit, and the normally open circuit is closed and an alarm signal is sent through the excessive deformation information of the vertical pole body transmitted by the deformation information transmission component.

[0007] Furthermore, the deformation information transmission component includes a pendant and a composite connected hanging component group. The pendant is suspended on the normally open circuit through the composite connected hanging component group fixedly installed at the top end on the monitoring base point. During the working process of the full hall formwork support, the normally open circuit closes and sends out an alarm signal through the bending, inclination, and settlement deformation information of the vertical rod body transmitted by the pendant in cooperation with the composite connected hanging component group.

[0008] The preferred way of the above solution is that the composite connected hanging component group includes a wire hanging conductive group and an electrode plate group. The wire hanging conductive group is connected into the normally open circuit through the specified position of the monitoring base point in cooperation with the pendant, and the electrode plate group is connected in parallel with the wire hanging conductive group into the normally open circuit in cooperation with the pendant. During the working process of the full hall formwork support, the inclination deformation information of the vertical rod body is transmitted to the normally open circuit through the wire hanging conductive group in cooperation with the pendant, the settlement deformation information of the vertical rod body is transmitted to the normally open circuit through the electrode plate group in cooperation with the pendant, and the bending deformation information of the vertical rod body is transmitted to the normally open circuit through the wire hanging conductive group and / or the electrode plate group in cooperation with the pendant.

[0009] Furthermore, the wire hanging conductive group includes a conductive hanging wire, a zero wire, and a conductive copper ring. The conductive copper ring is arranged on the normally open circuit. The upper end of the conductive hanging wire is fixed at the specified position of the monitoring base point. The pendant is suspended at the lower end of the conductive hanging wire passing through the conductive copper ring. The upper end of the conductive hanging wire is connected into the normally open circuit through the zero wire. During the working process of the full hall formwork support, the inclined and / or bent vertical rod body horizontally moves the conductive hanging wire to contact the conductive copper ring to close the normally open circuit and send out an alarm signal in cooperation with the monitoring base point.

[0010] The preferred way of the above solution is that the electrode plate group includes two electrode copper plates. One electrode copper plate is fixedly installed at the tip of the lower part of the pendant, and the other electrode copper plate is arranged on the normally open circuit. During the working process of the full hall formwork support, the vertical rod body with settlement deformation and / or bending deformation moves one electrode copper plate vertically along the pendant to contact the other electrode copper plate to close the normally open circuit and send out an alarm signal in cooperation with the monitoring base point and the conductive hanging wire.

[0011] Furthermore, the normally open circuit includes a power supply and two sets of circuits. The conductive copper ring and one electrode copper plate are respectively connected in series on different circuits. Alarm components are respectively connected in series on the two sets of circuits.

[0012] The preferred way of the above solution is that the alarm component includes two groups of warning lights and two prompting speakers. One group of warning lights and one prompting speaker are respectively connected in series on each set of circuits.

[0013] Furthermore, the power supply includes a storage battery and a photovoltaic power generation panel. The storage battery is powered by the photovoltaic power generation panel.

[0014] The beneficial effects of the present invention are as follows: The technical solution provided by this application is based on each vertical rod body arranged in the full hall formwork support. By adding monitoring base points and a real-time alarm device for composite monitoring of the deformation of the vertical rods, a deformation monitoring system of this application is constituted, and the monitoring base points are arranged at the tops of the vertical rod bodies at specified positions. Then, during the working process of the full hall formwork support, the bending, inclination, and settlement deformation of the vertical rod bodies at the specified positions are monitored by the real-time alarm device for composite monitoring of the deformation of the vertical rods in cooperation with the monitoring base points, and an alarm signal is sent when the deformation exceeds the standard. This solves the technical problem in the prior art that when the vertical rod bodies in the full hall formwork support are deformed, it completely requires manual use of devices such as plumb bobs, wire plummets, and total stations on-site for practical measurement. After adopting the deformation monitoring system of this application, when the vertical rod bodies have excessive inclination, settlement, and bending deformation, through the cooperation of the real-time alarm device for composite monitoring of the deformation of the vertical rods and the monitoring base points, an alarm signal can be invented in real time to achieve real-time monitoring of the deformation. Except for arranging the monitoring base points and the real-time alarm device for composite monitoring of the deformation of the vertical rods, the entire monitoring process does not require manual participation and is completely completed by the real-time alarm device for composite monitoring of the deformation of the vertical rods. This not only significantly reduces the degree of manual participation in monitoring and improves the convenience of inspection, but also can send signals for excessive deformation at any time to prompt the operator to process immediately.

[0019] Such as Figure 1 、 Figure 2 and Figure 3Shown is a deformation monitoring system for the vertical poles of a full hall formwork support, which has little human participation, is convenient for inspection, and can send signals for excessive deformation at any time. The deformation monitoring system includes each vertical pole body 1 arranged in the full hall formwork support. The deformation monitoring system also includes a monitoring base point 2 and a real-time alarm device for comprehensive monitoring of the deformation of the vertical poles. The monitoring base point 2 is arranged at the top of the vertical pole body 1 at a specified position. During the working process of the full hall formwork support, the bending, inclination, and settlement deformation of the vertical pole body 1 at the specified position are monitored by the real-time alarm device for comprehensive monitoring of the deformation of the vertical poles in cooperation with the monitoring base point 2, and an alarm signal is sent when the deformation exceeds the standard. The technical solution provided in this application is based on each existing vertical pole body arranged in the full hall formwork support. By adding a monitoring base point and a real-time alarm device for comprehensive monitoring of the deformation of the vertical poles, the deformation monitoring system of this application is constituted, and the monitoring base point is arranged at the top of the vertical pole body 1 at a specified position. Then, during the working process of the full hall formwork support, the bending, inclination, and settlement deformation of the vertical pole body 1 at the specified position are monitored by the real-time alarm device for comprehensive monitoring of the deformation of the vertical poles in cooperation with the monitoring base point 2, and an alarm signal is sent when the deformation exceeds the standard. This solves the technical problem in the prior art that when the vertical pole body in the full hall formwork support is deformed, it is completely necessary for workers to use devices such as plumb bobs, plumb lines, and total stations on-site for practical measurements. After adopting the deformation monitoring system of this application, when the vertical pole body has excessive inclination, settlement, and bending deformation, the real-time alarm device for comprehensive monitoring of the deformation of the vertical poles can send out an alarm signal in cooperation with the monitoring base point in real time to realize real-time monitoring of the deformation. Except for arranging the monitoring base point and the real-time alarm device for comprehensive monitoring of the deformation of the vertical poles, the entire monitoring process does not require human participation and is completely completed by the real-time alarm device for comprehensive monitoring of the deformation of the vertical poles. This not only significantly reduces the degree of human participation in monitoring, improves the convenience of inspection, but also can send signals for excessive deformation at any time to prompt the operator to deal with it immediately. Considering the existing technology, the real-time alarm device for comprehensive monitoring of the deformation of the vertical poles in this application can adopt an existing scanning device, and a monitoring point is marked at the top of the vertical pole body 1 at a specified position accordingly. The deformation of the vertical pole body 1 is monitored by continuously scanning the position change of the monitoring point. However, this monitoring method has a large investment cost and poor monitoring effect due to light reasons in the full hall formwork support. Therefore, this application provides another structural monitoring method.

[0020] That is, first, the monitoring base point 2 is set as a plastic-steel hanging bracket clamped to the top of the vertical rod body, and a reference point for monitoring is set thereon. Then, the reference point is led out through the conductive hanging wire 4 of the real-time alarm device for composite monitoring of vertical rod deformation. During the working process of the full hall formwork support, the real-time alarm device for composite monitoring of vertical rod deformation monitors the bending, inclination, and settlement deformation of the vertical rod body 1 by monitoring the position change of the specified reference point, so as to achieve the purpose of simplifying the structure. At the same time, the real-time alarm device for composite monitoring of vertical rod deformation in this application is set into the structure of an energized circuit, avoiding the situation of poor monitoring effect due to light reasons in the full hall formwork support.

[0021] Specifically, the real-time alarm device for the deformation compound monitoring of the upright pole in this application includes an alarm component, a normally open circuit, and a deformation information transmission component. The alarm component is connected in series to the normally open circuit, and the normally open circuit is closed and emits an alarm signal through the excessive deformation information of the upright pole body 1 transmitted by the deformation information transmission component. Based on the complexity of the deformation of the upright pole body and combined with the inventive concept of this application that the circuit closure forms a complete loop and then conducts the alarm component to emit an alarm signal, the deformation information transmission component of this application includes a pendant 3 and a composite connected hanging component group. The pendant 3 is suspended on the normally open circuit through the composite connected hanging component group with its top fixedly installed on the monitoring base point 2; during the working process of the full hall formwork support, the normally open circuit is closed and emits an alarm signal through the excessive bending, inclination, and settlement deformation information of the upright pole body 1 transmitted by the pendant 3 in cooperation with the composite connected hanging component group. At this time, the composite connected hanging component group includes a wire hanging conductive group and an electrode plate group. The wire hanging conductive group is connected into the normally open circuit through the specified position of the monitoring base point 2 in cooperation with the pendant 3, and the electrode plate group is connected into the normally open circuit in parallel with the wire hanging conductive group in cooperation with the pendant 3; during the working process of the full hall formwork support, the inclination deformation information of the upright pole body 1 is transmitted to the normally open circuit through the wire hanging conductive group in cooperation with the pendant 3, the settlement deformation information of the upright pole body 1 is transmitted to the normally open circuit through the electrode plate group in cooperation with the pendant 3, and the bending deformation information of the upright pole body 1 is transmitted to the normally open circuit through the wire hanging conductive group and / or the electrode plate group in cooperation with the pendant 3. More specifically, the wire hanging conductive group includes a conductive hanging wire 4, a zero wire 5, and a conductive copper ring 6. The conductive copper ring 6 is arranged on the normally open circuit. The upper end of the conductive hanging wire 4 is fixed at the specified position of the monitoring base point 2, and the pendant 3 is suspended at the lower end of the conductive hanging wire 4 passing through the conductive copper ring 6. The upper end of the conductive hanging wire 4 is connected into the normally open circuit through the zero wire 5; during the working process of the full hall formwork support, the inclined and / or bent upright pole body 1 moves the conductive hanging wire 4 horizontally in cooperation with the monitoring base point 2 to contact the conductive copper ring 6 to close the normally open circuit and emit an alarm signal. The electrode plate group includes two electrode copper plates 7. One electrode copper plate 7 is fixedly installed at the tip of the lower part of the pendant, and the other electrode copper plate 7 is arranged on the normally open circuit; during the working process of the full hall formwork support, the settling and / or bent upright pole body 1 moves one electrode copper plate 7 vertically through the pendant 3 in cooperation with the monitoring base point 2 and the conductive hanging wire 4 to contact the other electrode copper plate 7 to close the normally open circuit and emit an alarm signal. Correspondingly, the normally open circuit of this application includes a power supply and two sets of circuits. The conductive copper ring 6 and one electrode copper plate 7 are respectively connected in series to different circuits; alarm components are respectively connected in series to the two sets of circuits. The power supply includes a storage battery 8 and a photovoltaic power generation panel, and the storage battery 8 is powered by the photovoltaic power generation panel.Based on the need to emit different alarm signals based on different deformations, the alarm component of this application includes two groups of warning lights 9 and two prompting horns 10. One group of warning lights 9 and one prompting horn 10 are connected in series on each loop. Of course, different warning lights 9 can emit different alarm lights, and different horns 10 emit different alarm sounds for distinction.

[0022] In short, the working principle of the technical solution of this application is as follows: When the formwork support settles, the pendant moves downward, driving the electrode copper sheet 7 thereon to contact the electrode copper sheet 7 in the circuit to connect the circuit and trigger the lower alarm and warning lights; when the frame deflects, the pendant deflects left and right, front and back, and the conductive hanging steel wire 4 contacts the conductive copper ring 6 to connect the circuit and trigger the upper alarm and warning lights; the settlement and deflection distances are both set in accordance with the scaffolding safety management regulations, and an alarm is issued when the required value is exceeded.

[0023] In summary, adopting the technical solution provided by this application also has the following advantages.

[0024] 1. By designing a conductive plumb bob and a contact reaction device for physical linkage, when the support vertical pole deflects or settles and compresses, when the deformation amount exceeds the set value, the alarm device will be triggered for warning;

[0025] 2. After the formwork support is erected until it is demolished after pouring, the device can be used to check or record whether continuous alarms occur, which is convenient for inspection and reduces the need for personnel to walk inside the support, especially during the concrete pouring period.

[0026] The technical solution of this application will be further described below through specific embodiments:

[0027] Embodiment 1

[0028] The technical solution in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in this application belong to the scope of protection of this application.

[0029] For the formwork support vertical poles from erection until demolition, in order to ensure construction safety and convenient monitoring, it is necessary to improve a monitoring device that can not only improve construction efficiency, but also ensure personnel safety and save construction costs.

[0030] Main construction method: At the top of the vertical pole of the formwork support, a plumb bob is suspended at an appropriate distance from the vertical pole by a plastic-steel hanging clip. The hanging clip is non-conductive, while the pendant wire and the plumb bob are conductive. The lower plumb bob is placed inside the monitoring device, and the monitoring device is fixed to the bottom plate by bolts. The monitoring reaction device is provided with a triggering mechanism for inclination and vertical deformation, mainly through the offset of the plumb bob and the contact on the monitoring device to conduct an electrical reaction. A storage battery is installed inside the monitoring device. The live wire of the storage battery is connected to an alarm (lamp and horn), and the neutral wire is transmitted to the plumb bob through the vertical pole and the hanging wire. When the vertical pole deforms, it will cause the plumb bob to swing. When the swing exceeds the set limit, the switch is triggered to continuously alarm.
