Description

Technical Field

[0001] This invention relates to a deformation monitoring system, and more particularly to a deformation monitoring system for the uprights of a full-span formwork support, belonging to the field of design and manufacturing technology of construction equipment for road and bridge engineering. Background Technology

[0002] Currently, deformation monitoring of most formwork support uprights is conducted manually on-site using equipment such as plumb bobs, plumb lines, and total stations. Since most formwork support components are densely packed, real-time measurement is inconvenient, and there are safety risks associated with personnel walking inside the formwork, especially during concrete pouring when the safety risks increase exponentially. Furthermore, manual on-site measurement for formwork support upright deformation significantly increases labor costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a deformation monitoring system for uprights of full-span formwork, which requires little manual intervention, is convenient to inspect, and can send signals for excessive deformation at any time.

[0004] The technical solution adopted to solve the above-mentioned technical problems is: a deformation monitoring system for uprights of a full-span formwork support, including each upright body arranged in the full-span formwork support. The deformation monitoring system also includes a monitoring base point and a real-time alarm device for composite monitoring of upright deformation. The monitoring base point is arranged on the top of the upright body at a specified position. During the operation of the full-span formwork support, the bending, tilting and settlement deformation of the upright body at the specified position is monitored by the real-time alarm device for composite monitoring of upright deformation in conjunction with the monitoring base point, and an alarm signal is issued when the deformation exceeds the standard.

[0005] Furthermore, the monitoring base point is composed of a plastic steel hanger frame that is hooped to the top of the upright body. The benchmark point monitored by the composite monitoring and real-time alarm device for upright deformation is set at the specified position of the plastic steel hanger frame. During the operation of the full-span formwork support frame, the composite monitoring and real-time alarm device for upright deformation monitors the bending, tilting and settlement deformation of the upright body by monitoring the position changes of the specified benchmark point.

[0006] The preferred embodiment of the above scheme is that the pole deformation composite monitoring real-time alarm device includes an alarm component, a normally open circuit, and a deformation information transmission component. The alarm component is connected in series with the normally open circuit. The normally open circuit closes and sends an alarm signal when the excessive deformation information of the pole body is transmitted through the deformation information transmission component.

[0007] Furthermore, the deformation information transmission component includes a pendant and a composite connecting suspension assembly. The pendant is suspended from the normally open circuit via the composite connecting suspension assembly fixed at the top of the monitoring base point. During the operation of the full-span formwork support, the normally open circuit transmits information on the excessive bending, tilting, and settlement deformation of the upright body through the pendant in cooperation with the composite connecting suspension assembly, and then closes and issues an alarm signal.

[0008] The preferred embodiment of the above scheme is that the composite connecting suspension assembly includes a wire suspension conductive assembly and an electrode assembly. The wire suspension conductive assembly is connected to a normally open circuit at a specified position of the monitoring base point with the assistance of a plumb bob. The electrode assembly is connected to the normally open circuit in parallel with the wire suspension conductive assembly with the assistance of a plumb bob. During the operation of the full-span formwork support, the tilt deformation information of the upright body is transmitted to the normally open circuit through the wire suspension conductive assembly with the assistance of a plumb bob. The settlement deformation information of the upright body is transmitted to the normally open circuit through the electrode assembly with the assistance of a plumb bob. The bending deformation information of the upright body is transmitted to the normally open circuit through the wire suspension conductive assembly and / or the electrode assembly with the assistance of a plumb bob.

[0009] Furthermore, the wire-suspended conductive assembly includes a conductive suspension wire, a neutral wire, and a conductive copper ring. The conductive copper ring is arranged on a normally open circuit. The upper end of the conductive suspension wire is fixed at a specified position of the monitoring base point. The pendant is suspended from the lower end of the conductive suspension wire that passes through the conductive copper ring. The upper end of the conductive suspension wire is connected to the normally open circuit through the neutral wire. During the operation of the full-span formwork support, the tilted and / or bent pole body moves horizontally with the cooperation of the monitoring base point. The conductive suspension wire contacts the conductive copper ring, closes the normally open circuit, and sends an alarm signal.

[0010] The preferred embodiment of the above scheme is that the electrode assembly includes two copper electrode plates, one of which is fixed on the tip of the lower part of the pendant, and the other is arranged on the normally open circuit. During the operation of the full-span formwork support, the vertical pole body with settlement deformation and / or bending deformation, in coordination with the monitoring base point and the conductive hanging steel wire, moves vertically along the pendant. One copper electrode plate contacts the other copper electrode plate to close the normally open circuit and issue an alarm signal.

[0011] Furthermore, the normally open circuit includes a power supply and two circuits, with a conductive copper ring and an electrode copper sheet connected in series in different circuits; alarm components are connected in series in each of the two circuits.

[0012] The preferred embodiment of the above scheme is that the alarm component includes two sets of warning lights and two warning horns, with one set of warning lights and one warning horn connected in series on each circuit.

[0013] Furthermore, the power source includes a battery and a photovoltaic panel, with the battery providing electricity through the photovoltaic panel.

[0014] The beneficial effects of this invention are as follows: The technical solution provided in this application is based on the existing uprights arranged in the full-span formwork frame. By adding monitoring base points and a real-time alarm device for composite monitoring of upright deformation, the deformation monitoring system of this application is constructed. The monitoring base points are arranged at the top of the uprights at designated locations. Then, during the operation of the full-span formwork frame, the bending, tilting, and settlement deformation of the uprights at the designated locations are monitored by the real-time alarm device for composite monitoring of upright deformation in conjunction with the monitoring base points, and an alarm signal is issued when the deformation exceeds the standard. This invention solves the technical problem in existing technologies where deformation of the uprights within a full-span formwork requires manual on-site measurement using instruments such as plumb bobs, line weights, and total stations. With the deformation monitoring system described in this application, when the upright exhibits excessive tilting, settlement, or bending deformation, the real-time alarm device for composite upright deformation monitoring, in conjunction with monitoring base points, can generate alarm signals in real time, achieving real-time deformation monitoring. Except for the setup of monitoring base points and the real-time alarm device for composite upright deformation monitoring, the entire monitoring process requires no manual intervention and is entirely completed by the device. This significantly reduces the degree of manual intervention in monitoring, improves the convenience of inspection, and allows for timely signaling of excessive deformation, prompting operators to take immediate action.

[0019] like Figure 1 , Figure 2 as well as Figure 3The diagram illustrates a deformation monitoring system for uprights in a full-span formwork scaffold, provided by this invention. This system features low manual intervention, convenient inspection, and the ability to issue signals for excessive deformation at any time. The deformation monitoring system includes upright bodies 1 arranged within the full-span formwork scaffold. It also includes monitoring base points 2 and a real-time alarm device for combined monitoring of upright deformation. Monitoring base points 2 are located on the top of the upright bodies 1 at designated positions. During the operation of the full-span formwork scaffold, the bending, tilting, and settlement deformation of the upright bodies 1 at the designated positions are monitored by the real-time alarm device for combined monitoring of upright deformation, in conjunction with the monitoring base points 2. An alarm signal is issued when the deformation exceeds the standard. The technical solution provided in this application is based on the existing uprights arranged in the full-span formwork. By adding monitoring base points and a real-time alarm device for composite monitoring of upright deformation, the deformation monitoring system of this application is constructed. The monitoring base points are arranged on the top of the uprights at designated locations. Then, during the operation of the full-span formwork, the bending, tilting, and settlement deformation of the uprights at the designated locations are monitored by the real-time alarm device for composite monitoring of upright deformation in conjunction with the monitoring base points, and an alarm signal is issued when the deformation exceeds the standard. This invention solves the technical problem in existing technologies where deformation of the uprights within a full-span formwork requires manual on-site measurement using instruments such as plumb bobs, line weights, and total stations. With the deformation monitoring system described in this application, when the upright exhibits excessive tilting, settlement, or bending deformation, the real-time alarm device for composite upright deformation monitoring, in conjunction with monitoring base points, can generate alarm signals in real time, achieving real-time deformation monitoring. Except for the setup of monitoring base points and the real-time alarm device for composite upright deformation monitoring, the entire monitoring process requires no manual intervention and is entirely completed by the device. This significantly reduces the degree of manual intervention in monitoring, improves the convenience of inspection, and allows for timely signaling of excessive deformation, prompting operators to take immediate action. In light of existing technologies, the real-time alarm device for composite monitoring of pole deformation in this application can utilize existing scanning devices, with monitoring points marked on the top of the pole body 1 at designated locations. The deformation of the pole body 1 is monitored by continuously scanning the changes in the position of these monitoring points. However, this monitoring method suffers from high investment costs and poor monitoring effectiveness within a full-span formwork scaffold due to lighting conditions. Therefore, this application provides an alternative monitoring method with a different structure.

[0020] First, monitoring base point 2 is set as a plastic steel hanger clamped to the top of the upright body, and a monitoring reference point is set on it. Then, the conductive hanging steel wire 4 of the upright deformation composite monitoring real-time alarm device is used to lead out this reference point. During the operation of the full-span formwork, the upright deformation composite monitoring real-time alarm device monitors the bending, tilting, and settlement deformation of the upright body 1 by monitoring the positional changes of the specified reference point, thereby simplifying the structure. At the same time, this application sets the upright deformation composite monitoring real-time alarm device as an electrically conductive circuit, avoiding the situation where the monitoring effect is poor due to light conditions inside the full-span formwork.

[0021] Specifically, the real-time alarm device for composite monitoring of pole deformation in this application includes an alarm component, a normally open circuit, and a deformation information transmission component. The alarm component is connected in series with the normally open circuit. The normally open circuit, through the deformation information transmission component, transmits information on the excessive deformation of the pole body 1, closes, and issues an alarm signal. Based on the complexity of pole body deformation and the inventive concept of this application, which is that a closed circuit forms a complete loop, thereby activating the alarm component to issue an alarm signal, the deformation information transmission component of this application includes a pendant 3 and a composite connecting suspension assembly. The pendant 3 is suspended from the normally open circuit through the composite connecting suspension assembly, which is fixed at its top to the monitoring base point 2. During the operation of the full-span formwork, the normally open circuit, through the pendant 3 and in cooperation with the composite connecting suspension assembly, transmits information on the excessive bending, tilting, and settlement deformation of the pole body 1, closes, and issues an alarm signal. At this time, the composite connecting suspension assembly includes a wire suspension conductive assembly and an electrode plate assembly. The wire suspension conductive assembly is connected to the normally open circuit through the specified position of the monitoring base point 2 with the assistance of the pendant 3. The electrode plate assembly is connected to the normally open circuit in parallel with the wire suspension conductive assembly with the assistance of the pendant 3. During the operation of the full-span formwork support frame, the tilt deformation information of the upright body 1 is transmitted to the normally open circuit through the wire suspension conductive assembly with the assistance of the pendant 3. The settlement deformation information of the upright body 1 is transmitted to the normally open circuit through the electrode plate assembly with the assistance of the pendant 3. The bending deformation information of the upright body 1 is transmitted to the normally open circuit through the wire suspension conductive assembly and / or the electrode plate assembly with the assistance of the pendant 3. More specifically, the wire suspension conductive assembly includes a conductive suspension wire 4, a neutral wire 5, and a conductive copper ring 6. The conductive copper ring 6 is arranged on a normally open circuit. The upper end of the conductive suspension wire 4 is fixed at a specified position of the monitoring base point 2. The pendant 3 is suspended from the lower end of the conductive suspension wire 4 that passes through the conductive copper ring 6. The upper end of the conductive suspension wire 4 is connected to the normally open circuit through the neutral wire 5. During the operation of the full-span formwork support, the tilted and / or bent upright body 1 moves horizontally with the cooperation of the monitoring base point 2. The conductive suspension wire 4 contacts the conductive copper ring 6, closes the normally open circuit, and sends an alarm signal. The electrode assembly includes two copper electrode plates 7. One copper electrode plate 7 is fixed to the tip of the lower part of the pendant, and the other copper electrode plate 7 is arranged on the normally open circuit. During the operation of the full-span formwork support, the vertical pole body 1, which has undergone settlement deformation and / or bending deformation, moves vertically through the pendant 3 with the cooperation of the monitoring base point 2 and the conductive hanging steel wire 4. One copper electrode plate 7 contacts the other copper electrode plate 7, closing the normally open circuit and issuing an alarm signal. Accordingly, the normally open circuit of this application includes a power supply and two sets of circuits. The conductive copper ring 6 and the copper electrode plate 7 are connected in series in different circuits. Alarm components are connected in series in both circuits. The power supply includes a storage battery 8 and a photovoltaic power generation panel. The storage battery 8 provides electrical energy through the photovoltaic power generation panel.To meet the need for different alarm signals based on different configurations, the alarm component of this application includes two sets of warning lights 9 and two warning horns 10, with one set of warning lights 9 and one warning horn 10 connected in series in each circuit. Of course, different warning lights 9 can emit different alarm lights, and different horns 10 can 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 down and causes the electrode copper plate 7 on it to contact the electrode copper plate 7 in the circuit, thus triggering the lower alarm and warning light; when the frame shifts, the pendant shifts left, right, front, and back, and the conductive hanging steel wire 4 contacts the conductive copper ring 6, thus triggering the upper alarm and warning light; the settlement and shift distances are set in accordance with the scaffolding safety management regulations, and alarms will be triggered if the required values ​​are exceeded.

[0023] In summary, the technical solution provided in 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 column shifts or settles and is compressed, and the deformation exceeds the set value, an alarm device will be triggered to issue a warning.

[0025] 2. The device can be used to check and record whether there is a continuous alarm after the formwork is erected and before the concrete is poured and removed. This makes inspection convenient and reduces the need for personnel to walk inside the scaffold, especially during the concrete pouring process.

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

[0027] Example 1

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] To ensure construction safety and facilitate monitoring from the completion of the formwork erection until its dismantling, it is necessary to improve the monitoring device so as to enhance construction efficiency, ensure personnel safety, and save construction costs.

[0030] The main construction method involves using a plastic steel clamp to suspend a plumb bob at an appropriate distance from the top of the formwork support pole. The clamp is non-conductive, while the steel wire of the plumb bob and the plumb bob are conductive. The lower plumb bob is placed inside a monitoring device, which is fixed to the base plate with bolts. The monitoring device is equipped with a trigger mechanism for tilting and vertical deformation. It mainly reacts by contacting the plumb bob with the monitoring device when it deviates. A battery is installed inside the monitoring device. The live wire of the battery is connected to an alarm (light and horn), and the neutral wire is transmitted to the plumb bob through the pole to the suspension wire. When the pole deforms, it will cause the plumb bob to swing. When the swing exceeds the set limit, it will trigger a switch to continuously alarm.

This narrative style of the specification is merely for the purpose of clarity. Those skilled in the art should regard the specification as a whole.
