Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a temporary support system used in a construction phase. Background Art

[0002] Temporary support structures such as formwork and scaffolding are essential and important facilities in the construction process.

[0003] Publicly available document 1 (Research Progress and Development Path of Temporary Support Technology and Equipment for Coal Roadway Excavation, 2023) discloses a temporary support device primarily composed of a "front exploration beam + roof protection beam + lightweight single-column" system. After reserving a certain clearance ahead of the roadway excavation, this temporary support device utilizes fiberglass single-column pillars to bring the roof protection beam into contact with the roadway's empty roof area, providing strong horizontal roof control. Simultaneously, the front exploration beam is moved forward through the front exploration beam extension groove, and the beam extension device is rotated to bring the front exploration beam into contact with the roof, providing auxiliary longitudinal roof control. This creates a "combined beam" roof control structure with the roof protection beam, providing support for the empty roof area in a "surface" manner. However, the design phase of this temporary support device relies primarily on manual calculations and experience, which is prone to errors and consumes a significant amount of manpower and time.

[0004] Publicly available document 2 (Finite Element Analysis of a Temporary Support for Rapid Top Coal Excavation, 2021) discloses a temporary support for rapid top coal excavation. This temporary support is a tunnel support device consisting of an internal frame, an external frame, and a cylinder. Driven by a hydraulic system, it provides timely support for the newly exposed roof after the tunnel boring machine cuts, expanding the support area, shortening the permanent support time, and improving tunneling efficiency. SolidWorks modeling and ANSYS finite element analysis have verified its safety under uniform, front-loaded, and eccentrically loaded conditions. However, this temporary support lacks an automated temporary support structure design and real-time monitoring system that integrates information technology, resulting in safety issues.

[0005] Therefore, there is an urgent need to develop an intelligent, safe and reliable temporary support system to improve construction safety and work efficiency. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a temporary support system for the construction phase, which automatically extracts building model parameters through the Revit API interface, automatically checks stress in combination with the safety redundancy coefficient, dynamically adjusts the support spacing or cross-sectional size, and ensures the safety and reliability of the temporary support equipment structural design through the algorithm logic of the safety redundancy check, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A temporary support system for the construction phase, comprising temporary support equipment, a BIM automation plug-in module, a real-time monitoring module, and a cloud server; the temporary support equipment includes a flat plate formwork and a wall formwork; the BIM automation plug-in module designs the components of the temporary support equipment through an API interface; the real-time monitoring module can monitor the deformation and displacement of the temporary support equipment during the construction phase in real time; and the cloud server processes and analyzes the received data in real time;

[0009] The Revit platform plug-in in the BIM automation plug-in module has built-in safety redundancy check algorithm logic to ensure the safety and reliability of the temporary support equipment structure design. The specific steps are as follows:

[0010] Step Y1: The plug-in calls the Revit API interface to obtain structural geometric parameters, material characteristic parameters and load conditions from the Revit building model, and performs load calculation and stress analysis to calculate the component stress value under the preliminary design scheme. The initial maximum stress is σ max0 ;

[0011] Step Y2: The plug-in automatically calls a preset safety redundancy coefficient algorithm and selects a safety redundancy coefficient according to the construction conditions. The safety redundancy coefficient has a value range of 1.2-1.5.

[0012] Step Y3: After determining the safety redundancy coefficient, the plug-in automatically multiplies the initially calculated component stress value by the redundancy coefficient to obtain an adjusted stress verification value;

[0013] Step Y4: The plug-in automatically compares the adjusted calibration stress value σ through the Revit API. check and the material allowable stress value Fb', if σ check >Fb': Adjust support spacing and increase section height, and perform real-time iterative calculations until the ACI specification is met.

[0014] As a further embodiment of the present invention, temporary support equipment includes a flat plate formwork and a wall formwork, including the following specific features: The flat plate formwork is used for the construction of horizontal concrete components and is composed of plywood or formwork. In combination with a temporary support system such as support beams, pillars, and crossbeams, it provides shape control for the floor slab during the concrete pouring phase. The wall formwork is used for the construction of vertical concrete walls and is composed of steel formwork panels connected and fixed by bolts and support rods to form a solid overall structure.

[0015] As a further solution of the present invention, a BIM automation plug-in module designs components of temporary support equipment through an API interface, including the following specific contents: the BIM automation plug-in module is based on BIM technology and is developed as a Revit platform plug-in for designing temporary support equipment. The plug-in is implemented using the open secondary development interface provided by Revit, namely the API (Application Programming Interface), and is programmed using the C# language to ensure that it can be integrated with the existing mainstream BIM platform. The plug-in can automatically identify and extract geometric dimension data of concrete slabs and walls in the Revit building information model through the API interface, including core parameters such as slab thickness, span, wall height and length, and call and read the predefined material information database in the model in real time, which covers the physical property parameters of various commonly used support materials such as wood and steel, such as elastic modulus, compressive strength, flexural strength, material density, etc. These parameters are strictly calibrated and verified in advance to ensure that the parameters are true and reliable and can meet actual construction needs.

[0016] The BIM automation plug-in module automatically determines the component support method, analyzes the stress conditions, calculates the maximum bending moment, and automatically selects the optimal support scheme and cross-sectional dimensions to ensure that the temporary support structure design complies with the specifications and avoid human omissions and misjudgments. The specific steps are as follows:

[0017] In step S1, the plug-in automatically extracts the required formwork structural information through the Revit API interface, including formwork dimensions (span, thickness), material properties (such as elastic modulus, flexural strength, allowable stress value), and construction load information (concrete weight, construction live load, accidental load, etc.); based on the above information, the plug-in automatically predicts the initial support method according to the span of the formwork: when the formwork span is less than or equal to 3 meters, the plug-in gives priority to the simply supported support method, that is, a single-span arrangement; when the formwork span is greater than 3 meters, the plug-in automatically gives priority to the double-span continuous support method.

[0018] Step S2: After the initial support mode is determined, the plug-in calculates the maximum bending moment under different support modes. The maximum bending moment calculation formula for the simply supported beam mode is: Among them, M max is the maximum bending moment of the simply supported beam, q total is the total construction load, L is the formwork span; the maximum bending moment calculation formula for the double-span continuous support method is: Among them, M' max It is the maximum bending moment of the double-span continuous support method.

[0019] As a further aspect of the present invention, a real-time monitoring module is capable of monitoring the deformation and displacement of temporary support equipment during construction. Specifically, the module includes several wireless sensor nodes installed at key stress-bearing locations and deformation-sensitive areas of the temporary support equipment. These sensor nodes primarily include two types: ultrasonic sensor nodes and flexible strain sensor nodes. By transmitting and receiving ultrasonic signals, the ultrasonic sensor nodes can accurately measure the vertical displacement of the formwork support during construction, particularly during concrete pouring and vibration, with millimeter-level accuracy and high anti-interference performance. The flexible strain sensor nodes can be attached to the surface of the formwork or key support components. By measuring minute strain changes on the component surface, they can reflect the real-time bending deformation state of the support structure. Their measurement sensitivity reaches micrometers or even submicrometers, and they offer excellent flexibility and adhesion, making them suitable for diverse structural surfaces. Furthermore, to ensure the real-time and efficient delivery of monitoring data, the sensor nodes incorporate a built-in microcontroller and wireless communication module, forming a low-power, low-latency, and highly stable sensor data acquisition and transmission unit that collects sensor measurement data in real time and automatically packages and transmits it. The data collected by the wireless nodes are transmitted to the gateway node in real time via Wi-Fi wireless communication technology based on the IEEE 802.11 protocol. The gateway node then uploads the data directly to the cloud server via the 4G or 5G cellular network for centralized storage and analysis. The transmission delay is usually less than a few seconds, ensuring accurate reflection of the real-time status of the construction site.

[0020] As a further solution of the present invention, the cloud server processes and analyzes the received data in real time, including the following specific contents: the cloud server deploys a real-time data analysis unit, which has a built-in Kalman filter algorithm to effectively filter out on-site noise and interference. At the same time, the cloud server also has a built-in threshold analysis and early warning algorithm logic, which sets safety threshold parameters. For example, the maximum displacement allowed for the template equipment shall not exceed 10 mm, and the maximum deformation allowed shall not exceed 500 microstrain. Once the real-time analysis algorithm on the Internet of Things platform automatically detects that the data collected by a certain sensor node exceeds the preset threshold, the system will immediately automatically trigger the early warning mechanism and push the alarm information to the mobile terminal devices of on-site construction personnel and management personnel in real time through the Internet of Things communication protocol, including mobile phone apps, WeChat mini-programs or SMS notifications. The notification content includes the specific location of the abnormality, the current abnormal parameter value, the specific risk level and emergency measures, such as requiring on-site personnel to immediately stop pouring concrete, add temporary support or urgently adjust the construction plan.

[0021] The technical effects and advantages of the temporary support system used in the construction phase of the present invention are as follows: the present invention automatically extracts building model parameters through the Revit API interface, and the algorithm developed based on the C# language can intelligently select simple support or double-span continuous support mode, automatically check stress in combination with the safety redundancy coefficient, and dynamically adjust the support spacing or cross-sectional dimensions. Using millimeter-level precision ultrasonic sensors and micron-level flexible strain sensors, data is uploaded to the cloud server in real time through low-power wireless nodes, combined with threshold analysis, to achieve a second-level response to abnormal situations, thereby improving the timeliness and accuracy of accident warnings. Compared with existing technologies, this system reduces the incidence of safety accidents of temporary support structures and improves construction efficiency through closed-loop management of "intelligent design + real-time monitoring + cloud-based warning".

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0028] Example 1

[0029] See Figure 1As shown in the structural schematic diagram, an embodiment of the present invention provides a temporary support system for the construction phase, which includes temporary support equipment, a BIM automation plug-in module, a real-time monitoring module and a cloud server; the temporary support equipment includes a flat plate formwork and a wall formwork; the BIM automation plug-in module designs the components of the temporary support equipment through an API interface; the real-time monitoring module can monitor the deformation and displacement of the temporary support equipment in real time during the construction phase; and the cloud server processes and analyzes the received data in real time.

[0030] In this embodiment, see Figure 2 The structural diagram shown is a temporary support device disclosed in the prior art that is mainly composed of a "front exploration beam + top protection beam + light single column" for matching and use. After a certain empty top distance is reserved in front of the tunnel excavation, the temporary support device uses a fiberglass single column to bring the top protection beam into contact with the empty top area of ​​the tunnel and perform horizontal strong top control. At the same time, the front exploration beam is moved forward through the front exploration beam extension groove, and the extension beam device is rotated to make the front exploration beam touch the top for longitudinal auxiliary top control, so that the front exploration beam and the top protection beam form a "combined beam type" top control structure, and support operations are performed on the empty top area of ​​the roof in the form of a "surface area". However, the design stage of this temporary support device mainly relies on manual calculations and experience, which is prone to errors and consumes a lot of manpower and time. See Figure 3 The schematic diagram shown shows a conventional temporary support structure for rapid top coal excavation. This temporary support, consisting of an inner frame, an outer frame, and a hydraulic cylinder, is a roadway support device. Driven by a hydraulic system, it provides timely support for newly exposed roof slabs after the roadheader cuts through the roof. This expands the support area, shortens the permanent support period, and improves excavation efficiency. SolidWorks modeling and ANSYS finite element analysis have verified its safety under uniform, front-loaded, and eccentrically loaded conditions. However, this temporary support structure lacks an automated temporary support structure design and real-time monitoring system integrated with information technology, resulting in safety issues.

[0031] Furthermore, temporary support equipment includes flat plate formwork and wall formwork, including the following details: Figure 4 As shown in the schematic diagram, the flat plate formwork is used for the construction of horizontal concrete elements and is composed of plywood or formwork, combined with a temporary support system such as supporting beams, pillars and beams to provide shape control of the floor slab during the concrete pouring stage. Figure 5 As shown in the schematic diagram, the wall formwork is used to construct a vertical concrete wall, which is composed of steel formwork panels, which are connected and fixed by bolts and support rods to form a strong overall structure.

[0032] Furthermore, the BIM automation plug-in module designs the components of the temporary support equipment through the API interface, including the following specific contents: the BIM automation plug-in module is based on BIM technology and is developed as a Revit platform plug-in for designing temporary support equipment. The plug-in is implemented using the open secondary development interface provided by Revit, namely the API (Application Programming Interface), and is programmed using the C# language to ensure that it can be integrated with the existing mainstream BIM platform. The plug-in can automatically identify and extract the geometric dimension data of the concrete slabs and walls in the Revit building information model through the API interface, including core parameters such as slab thickness, span, wall height and length, and call and read the predefined material information database in the model in real time, which covers the physical property parameters of various commonly used support materials such as wood and steel, such as elastic modulus, compressive strength, flexural strength, material density, etc. These parameters are strictly calibrated and verified in advance to ensure that the parameters are true and reliable and can meet actual construction needs.

[0033] The BIM automation plug-in module automatically determines the component support method and clarifies the impact of different support methods on the stress condition of the formwork component, so as to determine the actual stress level of the formwork component based on the calculated maximum bending moment, and automatically judge which support method can make the stress condition of the component more optimized and safer, and then guide the plug-in to automatically select and determine the optimal support scheme and cross-sectional size, ultimately ensuring that the design of the temporary support structure meets the requirements of the specification and effectively avoids subjective omissions and misjudgments in the human design process. At the same time, it avoids the occurrence of subjective omissions or misjudgments in the human design process. The specific steps are as follows:

[0034] In step S1, the plug-in automatically extracts the required formwork structural information through the Revit API interface, including formwork dimensions (span, thickness), material properties (such as elastic modulus, flexural strength, allowable stress value), and construction load information (concrete weight, construction live load, accidental load, etc.); based on the above information, the plug-in automatically predicts the initial support method according to the span of the formwork: when the formwork span is less than or equal to 3 meters, the plug-in gives priority to the simply supported support method, that is, a single-span arrangement; when the formwork span is greater than 3 meters, the plug-in automatically gives priority to the double-span continuous support method.

[0035] Step S2: After the initial support mode is determined, the plug-in calculates the maximum bending moment under different support modes. The maximum bending moment calculation formula for the simply supported beam mode is: Among them, M max is the maximum bending moment of the simply supported beam, q total is the total construction load, L is the formwork span; the maximum bending moment calculation formula for the double-span continuous support method is: Among them, M'max It is the maximum bending moment of the double-span continuous support method.

[0036] The plug-in has built-in safety redundancy check algorithm logic to ensure the safety and reliability of the temporary support equipment structure design. The specific steps are as follows:

[0037] In step Y1, the plug-in automatically calls the Revit API interface to obtain structural geometric parameters, material characteristic parameters and load conditions from the Revit building model, and performs initial load calculation and stress analysis according to the ACI specification requirements to calculate the component stress value under the preliminary design scheme. The initial maximum stress is σ max0 .

[0038] Step Y2: After completing the initial stress analysis, the plug-in automatically calls a preset safety redundancy coefficient algorithm and selects a safety redundancy coefficient according to the construction conditions. The value range of the safety redundancy coefficient is 1.2-1.5.

[0039] Step Y3: After determining the safety redundancy coefficient, the plug-in automatically multiplies the initially calculated component stress value by the redundancy coefficient to obtain the adjusted stress check value. The calculation formula is: σ check =σ max0 ×F s , where σ check is the actual check stress value after adjustment of the safety redundancy factor, F s is the safety redundancy factor.

[0040] Step Y4: The plug-in automatically calls the material allowable stress value Fb' through the Revit API and compares it with the adjusted calibration stress value: check ≤Fb', it means that the current design meets the safety requirements; if σ check>Fb', it indicates that the current design scheme has insufficient safety redundancy and there is a structural safety risk. The plug-in enters the automatic optimization design phase to adjust the spacing of the formwork supports and the cross-sectional size of the formwork to reduce structural stress and ultimately meet the safety standards required by the specifications. The step of adjusting the spacing of the formwork supports is as follows: based on the principle that the support spacing and the maximum bending moment of the component are in a square relationship in the bending theory of beam structures, the spacing between the formwork support rods is gradually reduced by 10% each time, and the maximum bending stress of the formwork component is recalculated in real time through the Revit API interface until the stress value meets the ACI specification requirements or reaches the preset minimum allowable spacing. The step of adjusting the cross-sectional size of the formwork is as follows: gradually increasing the cross-sectional height of the formwork component (i.e., the thickness of the formwork), utilizing the characteristic in structural mechanics that the moment of inertia increases with the cube of the cross-sectional height to reduce the bending stress, each time increasing by a fixed small step size of 5-10 mm, and recalculating the stress value through the Revit API, and repeating this process until the stress meets the specification requirements.

[0041] As a further aspect of the present invention, a real-time monitoring module is capable of monitoring the deformation and displacement of temporary support equipment during construction. Specifically, the module includes several wireless sensor nodes installed at key stress-bearing locations and deformation-sensitive areas of the temporary support equipment. These sensor nodes primarily include two types: ultrasonic sensor nodes and flexible strain sensor nodes. By transmitting and receiving ultrasonic signals, the ultrasonic sensor nodes can accurately measure the vertical displacement of the formwork support during construction, particularly during concrete pouring and vibration, with millimeter-level accuracy and high anti-interference performance. The flexible strain sensor nodes can be attached to the surface of the formwork or key support components. By measuring minute strain changes on the component surface, they can reflect the real-time bending deformation state of the support structure. Their measurement sensitivity reaches micrometers or even submicrometers, and they offer excellent flexibility and adhesion, making them suitable for diverse structural surfaces. Furthermore, to ensure the real-time and efficient delivery of monitoring data, the sensor nodes incorporate a built-in microcontroller and wireless communication module, forming a low-power, low-latency, and highly stable sensor data acquisition and transmission unit that collects sensor measurement data in real time and automatically packages and transmits it. The data collected by the wireless nodes are transmitted to the gateway node in real time via Wi-Fi wireless communication technology based on the IEEE 802.11 protocol. The gateway node then uploads the data directly to the cloud server via the 4G or 5G cellular network for centralized storage and analysis. The transmission delay is usually less than a few seconds, ensuring accurate reflection of the real-time status of the construction site.

[0042] As a further solution of the present invention, the cloud server processes and analyzes the received data in real time, including the following specific contents: the cloud server deploys a real-time data analysis unit, which has a built-in Kalman filter algorithm to effectively filter out on-site noise and interference. At the same time, the cloud server also has a built-in threshold analysis and early warning algorithm logic, which sets safety threshold parameters. For example, the maximum displacement allowed for the template equipment shall not exceed 10 mm, and the maximum deformation allowed shall not exceed 500 microstrain. Once the real-time analysis algorithm on the Internet of Things platform automatically detects that the data collected by a certain sensor node exceeds the preset threshold, the system will immediately automatically trigger the early warning mechanism and push the alarm information to the mobile terminal devices of on-site construction personnel and management personnel in real time through the Internet of Things communication protocol, including mobile phone apps, WeChat mini-programs or SMS notifications. The notification content includes the specific location of the abnormality, the current abnormal parameter value, the specific risk level and emergency measures, such as requiring on-site personnel to immediately stop pouring concrete, add temporary support or urgently adjust the construction plan.

[0043] The present invention automatically extracts building model parameters through the Revit API interface. The algorithm developed based on the C# language can intelligently select simple support or double-span continuous support methods, automatically check stress in combination with the safety redundancy factor, and dynamically adjust the support spacing or cross-sectional dimensions. Using millimeter-level precision ultrasonic sensors and micron-level flexible strain sensors, data is uploaded to the cloud server in real time through low-power wireless nodes. Combined with threshold analysis, it can achieve a second-level response to abnormal situations, improving the timeliness and accuracy of accident warnings. Compared with existing technologies, this system reduces the incidence of safety accidents in temporary support structures while improving construction efficiency through closed-loop management of "intelligent design + real-time monitoring + cloud-based warning."

[0044] Example 2

[0045] This embodiment provides a multi-dimensional comprehensive monitoring solution to effectively enhance the safety monitoring capability of the formwork structure during the construction phase. At the key nodes of the floor slab formwork and wall formwork at the actual construction site, the key nodes include the center position, edge position, and the connection nodes between the formwork and the supporting structure. A plurality of wireless vibration monitoring units consisting of three-axis acceleration sensor nodes are set to monitor the vibration response characteristics of the formwork structure during the pouring of concrete, the walking of construction workers, and the operation of mechanical equipment in real time and with high precision. The sensor node adopts a low-power MEMS (micro-electromechanical system) three-axis acceleration sensor widely used in actual engineering. Its measurement range is adjustable from ±2g to ±16g, and the resolution can be accurate to 0.001g, meeting the needs of high-precision and micro-vibration signal capture at the construction site. The hardware unit of the sensor node is further equipped with a low-power microcontroller module to realize real-time acquisition, filtering and data preprocessing of sensor data, and transmits the collected vibration data to the gateway node in real time and with low latency through the integrated ZigBee wireless communication module. In the cloud server, the present invention uses a fast Fourier transform (FFT) algorithm to perform spectral analysis on the vibration data received in real time to identify the vibration characteristics and frequency composition of the temporary support equipment under different load conditions. When the real-time analysis finds that the actual vibration data exceeds the set safety threshold range, the server will automatically trigger the early warning mechanism and push detailed alarm information to the smart terminal device (such as a mobile phone or tablet) of the on-site manager in real time. The alarm information includes the specific location of the abnormal template node, a detailed description of the abnormal state, and recommended on-site emergency response measures. This enables on-site personnel to respond quickly and implement effective intervention measures.
