Description

Technical Field

[0001] This invention relates to the field of building structure monitoring, and in particular to a composite sensor and measurement system for axial force and tilt of a plug-in type disc buckle support column. Background Technology

[0002] In modern building construction, socket-type disc-lock steel pipe scaffolding is widely used to construct high formwork systems, a practice that has become an industry standard (JGJ231-2011) and is mandatory. According to the standard, steel pipe scaffolding is assembled in modular units based on the spacing of the connecting discs on the uprights, typically 500mm. Since the uprights are slender structures, any imbalance in the support can lead to excessive axial force and tilting in certain areas of the steel pipes, potentially causing structural instability, scaffold collapse, and ultimately, a safety accident. Therefore, real-time monitoring of the axial force and tilt of the uprights during structural construction is crucial and is a core component of safety monitoring for high formwork systems.

[0003] Currently, the axial force on the uprights is monitored using independent digital pressure sensors or vibrating wire axial force gauges; the tilt of the uprights is monitored using independent tilt sensors. Existing technologies have the following problems:

[0004] 1. Low integration; two independent sensors are used to measure the axial force and tilt of the upright.

[0005] 2. Installation is difficult. Special mounting accessories are used to fix the axial force sensor at the top or bottom of the pole. Using special mounting accessories to fix the tilt sensor on the pole results in high installation costs.

[0006] 3. Sensor protection is difficult. Both types of sensors are installed on the outside of the pole, making them susceptible to human movement or damage during construction, resulting in high maintenance costs. Summary of the Invention

[0029] This invention provides a composite sensor for axial force and tilt of plug-in type disc-lock scaffold uprights. It employs a measuring assembly upright using the minimum module of the disc-lock standard, consisting of a sensor body, a pressure-bearing head plug-in adapter, and an adaptable upright assembly. This assembly is installed on the upright section to be measured in a high-formwork plug-in type disc-lock scaffold, serving as the shortest standard upright in a high-formwork system. It can be easily combined with existing high-formwork standard uprights without affecting the existing construction workflow of plug-in type disc-lock high-formwork. Specifically, a sensor component is located in the middle of the sensor body, which can collect axial force and tilt measurement data of the upright section to be measured. This invention features high integration, convenient installation, strong field adaptability, and low overall cost. It enables real-time, accurate, and reliable sensing of upright axial force and tilt, providing effective support for construction management, especially risk control in high-formwork systems.

[0030] The following is an appendix Figure 1 For reference, embodiments of the present invention will be described in detail so that those skilled in the art can readily implement the invention. The present invention can be embodied in many different forms and is not limited to the embodiments described herein.

[0031] like Figure 1 The diagram shows a structural schematic of a composite sensor for axial force and tilt adapted to the upright of a plug-in type disc buckle bracket in one embodiment.

[0032] The axial force and tilt composite sensor uses a measuring combination pole with the same shape as the standard disc buckle pole with the minimum module of the disc buckle standard. It can be used as the shortest standard pole in the high formwork socket type disc buckle scaffold combination pole. It is set at the pole position to be monitored in a high formwork socket type disc buckle scaffold combination pole. In specific use, if the pole position to be monitored is determined, the standard disc buckle pole at that position is replaced with the measuring combination pole. It is combined with multiple standard disc buckle poles and other axial force and tilt composite sensors to form a new high formwork socket type disc buckle scaffold combination pole.

[0033] Specifically, each standard disc buckle upright has the same structure, consisting of an upper upright, a connecting plate, and a lower connecting sleeve, with the connecting sleeve having a receiving hole. In a typical cascading process, the upper upright is tightly connected to the previous standard disc buckle upright by tightly engaging the bottom of the receiving hole in the lower connecting sleeve, and then tightly engages with the upper upright of the next standard disc buckle upright through the receiving hole in the lower connecting sleeve.

[0034] The measuring assembly pole structure is installed on the pole to be measured part of the high-support plug-in type disc buckle bracket assembly pole, and can be cascaded with the upper standard disc buckle pole and / or the lower standard disc buckle pole. It is composed of a sensor body 1, a pressure head plug-in adapter 2, and an adapter pole 3. The upper part of the sensor body 1 is connected to the pressure head plug-in adapter 2, and can be cascaded with the upper standard disc buckle pole by connecting the pressure head plug-in adapter 2. The lower part of the sensor body 1 is connected to the adapter pole 3, and can be cascaded with the lower standard disc buckle pole by connecting the adapter pole 3.

[0035] It should be noted that the upper standard disc buckle upright and the lower standard disc buckle upright can be a standard disc buckle upright or another upright that is adapted to the axial force and tilt composite sensor measurement combination of the plug-in type disc buckle bracket upright.

[0036] The sensor body 1 has a sensor component 101 in the middle, which is used to collect axial force measurement data and tilt measurement data of the test column part of the high formwork socket-type disc buckle bracket combination column, and send the collected axial force measurement data and tilt measurement data to the host computer so that the working status of the high formwork column can be monitored in real time through the platform software.

[0037] The structural material used in the composite axial force and tilt sensor is of a higher grade than that used in the plug-in type disc buckle support pole. For example, stainless steel structural components are used, and the support cross section is not smaller than that of a standard disc buckle pole. This ensures that the support strength is not reduced and no safety hazards are caused when using the composite sensor.

[0038] In one embodiment, the sensor body 1 is composed of a pressure-bearing head 11, a sealed measuring part, and a pole adapter connecting sleeve 12;

[0039] The pressure-bearing head 11 is located at the upper part of the sensor body 1, the sealing measurement part is located at the middle part of the sensor body, and the upright adapter connecting sleeve 12 is located at the lower part of the sensor body.

[0040] The pressure-bearing head 11 is provided with a pin hole 111 for the insertion of the pressure-bearing head socket adapter 2, so as to tightly connect the pressure-bearing head socket adapter 2 with the bottom of the receiving hole of the connecting sleeve at the bottom of the upper standard disc buckle upright; this solves the problem that the sensor body cannot be tightly connected with the bottom of the socket hole of the disc buckle upright, and can also use the standard pin of the upright to transmit the axial force to the composite sensor;

[0041] The sealed measuring unit contains the sensor component 101 sealed inside.

[0042] The pole adapter sleeve 12 has the same socket as the standard disc buckle pole for inserting the adapter pole 3.

[0043] In one specific embodiment, the diameter of the pressure-bearing head 11 is the same as the diameter of the standard disc buckle upright, and it can be directly inserted into the connecting sleeve of the upper standard disc buckle upright; the inner and outer diameters of the upright adapter connecting sleeve 12 are the same as the inner and outer diameters of the connecting sleeve at the lower part of the standard disc buckle upright, and it can be inserted into the adapter upright 3.

[0044] In one embodiment, such as Figure 1 As shown, the sealing measurement unit includes: a sealing ring 13 with a sealing space inside; and a measuring rod 14 disposed in the sealing space of the sealing ring, on which the sensor component 101 is disposed.

[0045] In one embodiment, the sensor component 101 transmits axial force measurement data and tilt measurement data to the host computer via a signal cable 15 leading from inside the sealing ring 13 to outside the sensor body 1.

[0046] In one specific embodiment, the sealing ring 13 is provided with a waterproof connector through which the signal cable 15 passes, so that the signal cable 15 can be led from inside the sealing ring 13 to outside the sensor body 1.

[0047] In one embodiment, the distance between the pressure head 11 and the pressure head socket fitting 2 inserted into the pin hole 111 is adjusted within a certain range by the screw hole, so as to tightly connect with the bottom of the receiving hole of the connecting sleeve at the lower part of the upper standard disc buckle upright.

[0048] In one embodiment, the adapter pole 3 is modified from a standard disc buckle pole, using the connecting plate retained by the standard disc buckle pole and the connecting sleeve at the lower part, as well as the pole insertion section obtained by cutting off a part of the upper end of the connecting plate of the standard disc buckle pole; so that the pole insertion section can be inserted into the receiving hole of the connecting sleeve of the next lower standard disc buckle pole and fit tightly.

[0049] In a preferred embodiment, the distance between the pin hole 111 of the pressure-bearing head 11 and the socket hole of the connecting sleeve of the adapting upright is the minimum module of the disc buckle standard, typically 500mm. Furthermore, to ensure that the distance between the pin hole 111 of the pressure-bearing head 11 and the socket hole of the connecting sleeve of the adapting upright is the minimum module of the disc buckle standard, the upright corresponding to the upper end of the connecting disc is cut off by the standard disc buckle upright.

[0050] In one embodiment, such as Figure 2 The circuit structure of the sensor component 101 includes:

[0051] Axial force sensing unit 111 is used to acquire the axial force measurement data by sensing changes in strain.

[0052] Tilt sensing unit 112 is used to collect the tilt measurement data;

[0053] Power management unit 113 is used to supply power to each unit;

[0054] The control unit 114 is connected to the axial force sensing unit 111, the tilt sensing unit 112 and the power management unit 113. It is used to control the uploading of the collected axial force measurement data and tilt measurement data to the host computer through the communication cable 15 and to control the power supply to each unit through the power management unit 113 via the communication cable 15.

[0055] In one embodiment, the axial force sensing unit 111 includes: a bridge strain gauge 1111 tightly attached to the measuring rod for sensing strain changes at the monitored rod portion and obtaining a corresponding axial force strain signal; a strain signal processing unit 1112 connected to the bridge strain gauge 1111 for performing signal conditioning processing on the axial force strain signal to obtain the axial force measurement data; and the tilt sensing unit 112 employs a high-precision triaxial MEMS sensor tightly attached to the measuring rod.

[0056] In one embodiment, such as Figure 2 As shown, the sensor component further includes a temperature sensing unit 115, which is connected to the control unit 114 and is used to collect temperature measurement data of the test pole part of the high-support plug-in type disc buckle bracket combination pole, so that the control unit can control the upload of the temperature measurement data to the host computer through the communication cable.

[0057] In one embodiment, the sensor component 101 is a fully digital sensor with an editable address. Multiple composite sensors can be cascaded through a communication bus, facilitating on-site composite sensor data management and transmission.

[0058] To better describe the composite sensor for axial force and tilt of the plug-in type disc buckle bracket upright, the following specific embodiments are provided for illustration;

[0059] Example 1: A composite sensor for axial force and tilt adapted to the upright of a socket-type disc buckle bracket; the composite sensor for axial force and tilt adapted to the upright of a socket-type disc buckle bracket is a composite sensor combined with the upright structure.

[0060] The composite sensor structure is adapted to the combination method of the plug-in type disc buckle bracket upright. The composite sensor has a cylindrical structure and is divided into three independent parts, including the sensor body, the pressure head plug-in adapter, and the adapter upright. When the three are used together, they form a composite sensor combination upright, which can be used as a minimum module standard disc buckle upright.

[0061] The sensor body consists of four parts: a pressure head, a measuring rod, a sealing ring, and a vertical rod adapter connecting sleeve.

[0062] The measuring sensor and related circuitry are mounted on the measuring rod. Power supply and signal transmission for the circuitry are led to the sensor body via a signal cable passing through a waterproof connector with a sealing ring. A pressure head is used for cascading between the uprights of the disc-lock bracket. The diameter of the pressure head matches the diameter of the upright and can be directly inserted into the connecting sleeve of the upper standard upright. A pin hole is provided on the pressure head, allowing the axial force to be transmitted to the composite sensor even if the sensor body cannot be tightly fitted to the bottom of the socket hole on the disc-lock upright. The distance between the pin hole on the pressure head of the composite sensor and the socket hole on the connecting sleeve is the minimum module of the disc-lock standard, typically 500mm. The middle part of the sensor is the measuring rod, on which all sensing components and signal processing circuitry are mounted. Signals are led out via a communication cable. The lower part of the sensor is the connecting sleeve, with inner and outer diameters matching the standard upright. The socket hole on the connecting sleeve also matches the standard upright, used for the adapter upright of this composite sensor. A sealing ring is used to protect the measuring rod and sensor seal.

[0063] A socket adapter is provided on the upper part of the pressure head. The distance between the socket adapter and the pressure head can be adjusted by the screw hole of the pressure head. Within a certain range, the composite sensor body can be tightly connected to the bottom of the standard pole connecting sleeve.

[0064] The adapter pole is modified from the minimum module standard disc buckle pole; using the minimum module standard disc buckle pole, the connecting plate and the lower connecting sleeve are retained. In this invention, based on the minimum module distance between the pin hole on the composite sensor body and the pin hole of the adapter pole, which is usually 500mm, a part of the pole at the upper end of the connecting plate is cut off, so that the remaining upper pole section can be inserted into the connecting sleeve at the lower part of the composite sensor and fit tightly.

[0065] Measurement sensors and related circuits, such as Figure 3 As shown, the composite sensor monitors axial force and strain using a strain axial force sensing component, which is tightly mounted on the measuring rod in the middle of the sensor and sealed. The composite sensor's built-in strain gauge and strain signal conditioning unit sense the force on the composite sensor through strain changes. The composite sensor also incorporates a high-precision triaxial MEMS sensor, which is tightly mounted on the measuring rod in the middle of the sensor and sealed, enabling accurate measurement of the composite sensor's tilt data. Furthermore, the composite sensor incorporates a high-precision temperature sensor, capable of measuring the internal temperature of the composite sensor. The composite sensor connects to the external network via a communication cable, obtains power through a communication bus, and communicates with the host computer to transmit field measurement data. The composite sensor is a fully digital sensor with a built-in editable address; multiple composite sensors can be cascaded through the communication bus, facilitating on-site composite sensor data management and transmission.

[0066] The application method of the composite sensor includes:

[0067] Insert the upper end of the composite sensor adapter pole into the connecting sleeve at the lower part of the composite sensor. The connecting sleeve at the lower part of the composite sensor is used for connecting the standard pole. In this way, the disc buckle bracket pole of the part to be monitored is transformed into a combined pole with composite monitoring. The combined pole is used as the smallest modular component of the disc buckle bracket pole in high formwork.

[0068] Select the pole to be monitored, and change the original pole with an N-times modulus length to a combination of a pole with an N-1 times modulus length and a composite sensor combined pole. The combined pole can be placed above or below the N-1 times modulus pole. Taking the lower part as an example, insert the combined pole into the N-1 times modulus length pole connecting sleeve through the composite sensor socket on the combined pole, including the use of the bearing head adapter component. At the same time, the connecting sleeve on the combined pole is used to connect the lower standard pole. Through this operation, the disc buckle bracket pole of the part to be monitored is transformed into a pole with composite monitoring.

[0069] The composite sensor signal cable is connected to the host computer, and the data such as axial force, tilt and temperature are sent to the server through wireless or wired communication. Finally, the platform software realizes real-time monitoring of the working status of the high formwork support pole.

[0070] like Figure 4 The diagram shows a structural schematic of an axial force and tilt measurement system adapted to the upright of a plug-in type disc buckle bracket in one embodiment.

[0071] The system includes:

[0072] One or more axial force and tilt composite sensors 41 adapted to the plug-in type disc buckle support uprights and multiple standard disc buckle uprights 42 using the minimum module of the disc buckle standard can be combined to form a high-support plug-in type disc buckle support combination upright; the figure only takes one axial force and tilt composite sensor adapted to the plug-in type disc buckle support upright and a support upright with a module of 5 times as an example.

[0073] Each axial force and tilt composite sensor 41 uses a standard minimum module measuring combination pole with disc buckle, and is respectively set at a monitoring pole position of the high formwork socket type disc buckle bracket combination pole;

[0074] Furthermore, the measuring assembly pole consists of a sensor body, a pressure-bearing head socket adapter, and an adapter pole assembly.

[0075] The upper part of the sensor body is connected to the pressure-bearing head socket adapter, and can be cascaded with the upper standard disc buckle upright via the connection of the pressure-bearing head socket adapter; the lower part of the sensor body is connected to the adapter upright, and can be cascaded with the lower standard disc buckle upright via the connection of the adapter upright; wherein, the cascading of the upper and lower standard disc buckle uprights can employ a standard disc buckle upright or an axial force and tilt composite sensor adapted to the socket-type disc buckle bracket upright; it should be noted that... Figure 4 Taking the upper standard disc buckle upright and the lower standard disc buckle upright as the standard disc buckle upright 42 as an example, it can also be adapted to the axial force and tilt composite sensor 41 of the plug-in type disc buckle bracket upright.

[0076] The sensor body has a sensor component in the middle, which is used to collect axial force measurement data and tilt measurement data of the corresponding upright part to be measured, and send them to the host computer so that the host computer can realize real-time monitoring of the working status of the high-support plug-in type disc buckle bracket combination upright.

[0077] Since the implementation principle of the composite sensor for axial force and tilt of the upright of the adaptive plug-in type disc buckle bracket has been described in the previous embodiments, it will not be repeated here.

[0078] The present invention has the following advantages over the prior art:

[0079] 1. High integration: This invention simultaneously completes the measurement of axial force and tilt of the pole within a single integrated structure; the composite sensor is powered and communicates with data via a data bus.

[0080] 2. The composite sensor unit is compact and conforms to the technical standards of the plug-in disc buckle bracket upright. It can be used in a modular combination with standard disc buckle bracket uprights. It can not only measure axial force signals, but also simultaneously measure the three-dimensional tilt and temperature of the upright.

[0081] 3. Simple installation: For poles that need to monitor axial force and tilt, simply replace the ordinary pole with the measuring pole assembly with the composite sensor; if the measured part is an N-times module pole, then use an N-1 times module pole combined with the measuring pole assembly of this invention; thereby reducing the installation cost of the monitoring equipment.

[0082] 4. The composite sensor uses stainless steel structural components, which are high in strength. Only one signal cable is led out of the steel pipe, so it will not be moved or damaged by people during construction, resulting in low maintenance costs.

[0083] 5. Composite sensors can be recycled, resulting in low overall cost.

[0084] In summary, the axial force and tilt composite sensor and measurement system for plug-in type disc-lock scaffold uprights of the present invention employs a measuring assembly upright with the minimum module of the disc-lock standard, consisting of a sensor body, a pressure-bearing head plug-in adapter, and an adaptable upright assembly. This assembly is installed on the upright to be measured in the plug-in type disc-lock scaffold assembly uprights for high-formwork systems. It can be used as the shortest standard upright in high-formwork systems and can be easily combined with existing high-formwork standard uprights without affecting the existing construction workflow of plug-in type disc-lock high-formwork systems. In particular, the sensor body has a sensor component in the middle, which can collect axial force and tilt measurement data of the upright to be measured. The product of this invention has high integration, convenient installation, strong field adaptability, and low overall cost. It can achieve real-time, accurate, and reliable sensing of upright axial force and tilt, providing effective support for construction management, especially risk control in high-formwork systems. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0085] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
