Description

Technical Field

[0001] This invention relates to the field of structural engineering technology. More specifically, this invention relates to a modular, assembled mega-frame structure. Background Technology

[0002] With economic and social development, structural engineering is showing a trend towards larger scale, industrialization, and diversified application scenarios. Some special-function buildings require both high and large internal spaces, leading to the emergence of so-called megastructures. Like ordinary structural engineering, these tall, long-span megastructures also need to meet requirements such as high load-bearing capacity, high lateral stiffness, high construction efficiency, and low material consumption. For some special applications, they also require disassembly and reuse. Due to the special nature of these buildings, there are currently few application cases, and their structural forms and systems are still under development and improvement. Looking towards future application needs, there is an urgent need to provide more reasonable structural systems to adapt to the diverse needs and application scenarios of tall, long-span megastructures.

[0003] CN206916933U provides a truss-supported four-sided three-dimensional cable net curtain wall-mega-frame structure system, including a mega-frame structure and a planar prestressed cable net tensioned on the mega-frame structure. The mega-frame structure includes four three-dimensional lattice columns vertically fixed to a horizontal plane and four three-dimensional steel trusses horizontally overlapping the four three-dimensional lattice columns. The four three-dimensional lattice columns and the four three-dimensional steel trusses are welded together as a whole. This structural form suffers from weak stiffness, numerous converging members, and complex construction.

[0004] Existing detachable joint types for steel pipes include flanges and ear plates connected by high-strength bolts. These two joint types occupy a large space and are difficult to make equal to the strength of the rod under tension. Summary of the Invention

[0005] One objective of this invention is to provide a modular, assembled mega-frame structure in which the chords between modular units are assembled using threaded joints. Compared with conventional flange, ear plate, and bolt connections, this method occupies less space, has higher strength, and can achieve joint strength greater than that of the members, while also being more efficient in construction.

[0006] To achieve these objectives and other advantages of the present invention, a modular assembly mega-frame structure is provided, comprising: multiple mega-lattice columns and multiple mega-truss beams for sequentially connecting the tops of the multiple mega-lattice columns;

[0007] Both the giant lattice column and the giant truss beam are assembled from multiple modular units. Each modular unit includes four chords, planar straight web members for sequentially connecting the two ends of the four chords, and eight spatial web members. One end of each of the eight spatial web members is connected to a chord, and the other end is connected to a chord. In the modular unit of the giant lattice column, the chords are vertically arranged, and in the modular unit of the giant truss beam, the chords are horizontally arranged.

[0008] In each module unit, a first connecting pipe with internal threads is welded to one end of the chord, and a second connecting pipe with internal threads is welded to the other end. A threaded steel rod is screwed into the second connecting pipe. The threaded steel rod of one module unit in any two adjacent module units is screwed into the first connecting pipe of the other module unit to connect the two adjacent module units.

[0009] Preferably, in each module unit, a planar diagonal brace connects two adjacent chord members, and two diagonal braces connect any two adjacent rectangular lattice columns, with the two diagonal braces intersecting.

[0010] Preferably, it also includes multiple fixing seats, each corresponding to one of the multiple mega-lattice columns, to fix the mega-lattice columns. The fixing seats include:

[0011] A base for connecting to the ground or mounting foundation, the base having a receiving cavity for accommodating the bottom end of the giant lattice column;

[0012] Multiple sets of tilt sensors, with multiple tilt sensors in each set being equally spaced around the central axis of the giant lattice column, are used to output tilt vector data at the corresponding positions in real time.

[0013] The telescopic mechanism includes multiple drive components mounted on the base, and a common annular plate on the drive components. Multiple sets of first electric telescopic rods are provided within the annular plate. Each set of first electric telescopic rods is spaced apart along the length of the giant lattice column. Each set of first electric telescopic rods is connected to a first drive plate. The first drive plate can move up and down along the giant lattice column under the action of the drive components. When the lattice column needs adjustment, the electric telescopic rods drive the first drive plate to contact the giant lattice column.

[0014] The control module is connected to multiple tilt sensors, multiple drive components, and multiple electric telescopic rods. The control module can receive tilt vector data from each set of sensors and calculate the coordinates of the tilt point using a triangulation algorithm. When a tilt signal is detected, the control module controls multiple drive components to move the annular plate to the target position based on the tilt point coordinates. The first drive plate is then driven to move toward the giant lattice column via the electric telescopic rods.

[0015] Preferably, there are eight first drive plates, each corresponding to one of the four sides and one of the four vertical edges of the giant lattice column.

[0016] Preferably, multiple tilt sensors are spaced apart along the extension direction of the giant lattice column, and the tilt sensors are located inside the giant lattice column so that the first drive plate can act on the giant lattice column.

[0017] Preferably, the annular plate has a hollow structure and an open top. Multiple telescopic motors are provided inside the annular plate, and the ends of the multiple telescopic motors are provided with an annular auxiliary plate. Multiple sets of second electric telescopic rods are provided on the upper part of the auxiliary plate, and the ends of each set of second electric telescopic rods are connected to a second drive plate. The multiple second drive plates are arranged in a one-to-one correspondence with multiple first drive plates.

[0018] Preferably, when the control module performs tilt correction, if multiple tilt sensors simultaneously detect a tilt signal, the following steps are performed:

[0019] Step 1: Identify tilt sensors that are spatially continuous and have the same tilt direction as belonging to the same associated region;

[0020] Step 2: For the associated area, synchronously drive all the first electric telescopic poles corresponding to that area to move in coordination;

[0021] For independent tilt points that are not associated, adjust them one by one from bottom to top: when adjusting the lower tilt point, collect sensor data of the already adjusted points above in real time, and dynamically correct the current adjustment amount through a pre-compensation algorithm;

[0022] Step 3: Repeat step 2 until the overall tilt of the giant lattice column returns to the preset vertical range.

[0023] Preferably, the control module further includes a sensor self-diagnosis unit and a redundancy compensation unit;

[0024] The sensor self-diagnostic unit is used to periodically perform self-test operations on each group of tilt sensors, including zero-point drift calibration and signal continuity detection;

[0025] When the redundancy compensation unit detects a fault in any tilt sensor, it automatically ignores the sensor data and generates compensation data based on the tilt vector data of adjacent sensors through an interpolation algorithm.

[0026] The control module prioritizes using compensation data to execute the triangulation algorithm and correction control until the faulty sensor is repaired or replaced.

[0027] Preferably, the first drive board integrates a pressure sensor array, and the control module further includes a force feedback controller;

[0028] The pressure sensor array monitors the pressure distribution data of the contact surface between the first drive plate and the giant lattice column in real time. The force feedback controller dynamically calculates the optimal force application curve based on the pressure distribution data and adjusts the stroke speed and output force of the electric telescopic rod in real time through the PID algorithm.

[0029] When the pressure data exceeds the preset safety threshold, the force feedback controller immediately suspends the calibration operation and triggers an alarm.

[0030] Preferably, it also includes an early warning module;

[0031] The control module is preset with a first tilt threshold θ1 and a second tilt threshold θ2. When any tilt sensor detects a real-time tilt angle θ of θ1≤θ≤θ2, the control module activates the early warning module, issues an audible and visual alarm and records the tilt position. When the real-time tilt angle θ>θ2, it triggers an emergency stop alarm and sends a structural safety alarm to the remote monitoring terminal.

[0032] The present invention has at least the following beneficial effects:

[0033] First, the modular assembly mega-frame structure system of this invention uses steel pipes as structural components. Beams and columns are assembled from modular units composed of steel pipe lattice structures. These modular units are welded together from steel pipes, manufactured in a factory, and transported to the construction site where they are connected at assembly nodes to form a mega-frame structure. Inter-column cable supports may or may not be installed depending on stiffness requirements. The overall structure, from components and modular units to beams, columns, and supports, is standardized and highly integrated. The modular units are disassembled and reused, conforming to the trends of industrialization and green development.

[0034] Secondly, the giant frame system of the present invention has a simple structure, high rigidity and efficiency, and a high degree of standardization and industrialization. The present invention uses the connection between modular units through the internal thread of the chord tube to achieve the connection, which occupies less space and has higher strength than the conventional flange and ear plate bolt connection. The node strength can be greater than that of the rod, and the construction efficiency is high. The present invention adopts a modular assembly process, which can realize the height and span of the giant frame is adjustable and can be productized.

[0035] Third, this invention features a fixed base and an automatic adjustment system, which secures the giant lattice column through the base and receiving cavity. Multiple tilt sensors monitor the tilt status in real time, and the control module determines the tilt point using a triangulation algorithm. This determines the tilt point and directs the telescopic mechanism to move the annular plate, causing the first electric telescopic rod to drive the first drive plate for targeted correction. This closed-loop system automatically adjusts, reducing manual maintenance, ensuring the verticality of the lattice column, avoiding uneven load distribution, extending the frame's lifespan, and improving environmental adaptability and reliability.

[0036] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0043] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0044] According to one embodiment of the present invention, such as Figures 1-5 As shown, the present invention provides a modular assembled mega-frame structure, including: multiple mega-lattice columns and multiple mega-truss beams 1 for sequentially connecting the tops of the multiple mega-lattice columns 2;

[0045] Both the giant lattice column 2 and the giant truss beam 1 are assembled from multiple modular units. Each modular unit includes four chords 21, planar straight web members 23 for sequentially connecting the two ends of the four chords 21 (the four chords 21 and the eight planar straight web members 23 form a cube), and eight spatial web members 22. One end of each of the eight spatial web members 22 is connected to a chord 21, and the other end is connected to a chord 21. In the modular unit of the giant lattice column, the chords 21 are vertically arranged, and in the modular unit of the giant truss beam 1, the chords 21 are horizontally arranged.

[0046] In each module unit, one end of the chord member 21 is internally welded with a first connecting pipe 42 having internal threads, and the other end is internally welded with a second connecting pipe having internal threads. A threaded steel rod 41 is screwed into the second connecting pipe. The threaded steel rod 41 of one module unit is screwed into the first connecting pipe 42 of the other module unit to connect the two adjacent module units. One end of the eight spatial web members 22 is connected to the center of the module unit, and the other end is connected to the connection points of the four chord members 21 and the planar straight web members 23, forming a spatial support structure. When fabricating the modular unit, first, place the four chord members 21 in a rectangular distribution and fix their positions using welding fixtures. Then, weld the planar straight web members 23 to both ends of the four chord members 21 to form the upper and lower end faces of the rectangle. Next, weld one end of the eight spatial web members 22 together to form a node, and weld the other end to the corresponding positions of the four chord members 21 to complete the fabrication of a single modular unit. For the modular unit of the rectangular lattice column, the chord members 21 are arranged vertically and spliced. For the modular unit of the rectangular truss beam, the chord members 21 are arranged horizontally and spliced. The first connecting pipe 42 and the second connecting pipe can be made of seamless steel pipe, and their internal threads can be processed by a thread processing machine. The threaded steel bar 41 can be a high-strength bolt steel bar, and its surface threads can be processed by a thread rolling machine. A limiting ring is provided in the middle of the threaded steel plate, and the diameter of the limiting ring is equal to the diameter of the chord member. During the processing of the chord 21 of the modular unit, the first connecting pipe 42 and the second connecting pipe are welded to the inside of both ends of the chord 21 respectively to ensure a firm weld. Then, the threaded steel bar 41 is screwed into the second connecting pipe, leaving part of it exposed. When splicing two adjacent modular units, the exposed part of the threaded steel bar 41 of one modular unit is aligned with the first connecting pipe 42 of the other modular unit, and the modular unit is rotated to screw the threaded steel bar 41 into the first connecting pipe 42 until the end faces of the two modular units are tightly fitted, completing the connection. Using this technical solution, the present invention, through the structure and connection method of the chord 21 and the spatial web member 8, as well as the first connecting pipe 42, the second connecting pipe, and the threaded steel bar 41, can realize the rapid assembly and disassembly of the frame structure, facilitating transportation and on-site installation. At the same time, the structural design of each modular unit can ensure that the overall frame has good stability and load-bearing capacity, meeting the stress requirements during use.

[0047] According to another embodiment of the present invention, in each modular unit, a planar diagonal brace 24 connects two adjacent chord members 21, and two diagonal braces 3 connect any two adjacent rectangular lattice columns, with the two diagonal braces 3 arranged crosswise. By adding the planar diagonal brace 24 and the cross diagonal braces 3, the deformation resistance of the modular unit and the lateral stiffness of the entire frame structure can be further improved, making the frame more stable when subjected to horizontal loads such as wind and seismic forces.

[0048] According to yet another embodiment of the present invention, such as Figure 6 As shown, it also includes multiple fixing seats, which are arranged one-to-one with multiple giant lattice columns 2 to fix the giant lattice columns 2. The fixing seats include:

[0049] The base 31 is used to connect to the ground or the mounting foundation. The base 31 is provided with a receiving cavity 32 for accommodating the bottom end of the giant lattice column 2 (the size of the base 31 is larger than the cross-sectional size of the rectangular lattice column).

[0050] Multiple sets of tilt sensors, with multiple tilt sensors in each set being equally spaced around the central axis of the giant lattice column 2, are used to output tilt vector data at the corresponding positions in real time.

[0051] The telescopic mechanism includes multiple drive components 33 (the drive direction of the drive components 33 is vertical) mounted on the base 31. A ring plate 34 is shared on each drive component 33. Multiple sets of first electric telescopic rods 35 are provided within the ring plate 34 (the telescopic direction of the first electric telescopic rods is horizontal and either facing or away from the giant lattice column 2). Each set of first electric telescopic rods 35 is spaced apart along the length of the giant lattice column 2 (i.e., multiple first electric telescopic rods 35 in each set are spaced vertically, and the multiple sets of first electric telescopic rods 35 are equally spaced circumferentially along the central axis of the ring plate 34). Each set of first electric telescopic rods 35 is connected to a first drive plate 36 (the first drive plate 36 is vertically positioned). The first drive plate 36 can move up and down along the giant lattice column 2 under the action of the drive components 33. When it is necessary to adjust the lattice column, the electric telescopic rods drive the first drive plate 36 to contact the giant lattice column 2 (the ring plate 34 moves up and down along the giant lattice column).

[0052] The control module is connected to multiple sets of tilt sensors, multiple drive components 33, and multiple electric telescopic rods. The control module receives tilt vector data from each set of sensors and calculates the coordinates of the tilt point using a triangulation algorithm. When a tilt signal is detected, the control module controls the multiple drive components 33 to move the annular plate 34 to the target position based on the tilt point coordinates. The electric telescopic rods then drive the first drive plate 36 towards the giant lattice column 2. Each set of tilt sensors can include four sensors, evenly spaced circumferentially along the central axis of the rectangular lattice column, with an angle of 90° between adjacent sensors. Alternatively, each set can have eight sensors, with an angle of 45° between adjacent sensors. The drive components 33 are used to drive the annular plate 34 up and down. The drive components 33 can be telescopic cylinders, and there can be four of them. The horizontal cross-section of the annular plate 34 is square. The giant lattice column 2 passes through the annular plate 34, and the size of the annular plate 34 is larger than the size of the giant lattice column 2 to allow the annular plate 34 to move up and down along the length of the giant lattice column 2. The base 31 can be made of reinforced concrete with an internal steel reinforcement frame for added strength. The first electric telescopic rod 35 can be a DC electric actuator. The control module can be a PLC controller with a data acquisition module and a motor drive module. The base 31 is embedded in the ground or in the installation foundation, with its top flush with the ground. The receiving cavity 32 is located at the center of the base 31, and its dimensions match the bottom of the rectangular lattice column. An annular plate 34 is installed at the output end of the drive assembly 33, and the first electric telescopic rod 35 is installed inside the annular plate 34. The first drive plate 36 is connected to the end of the first electric telescopic rod 35. The control module is installed in a control cabinet on one side of the base 31. When the rectangular lattice column is installed, its bottom end is inserted into the receiving cavity 32 of the base 31 for initial fixation. The tilt sensor detects the tilt state of the lattice column in real time, outputs tilt vector data, and transmits it to the control module. After receiving the data, the control module calculates the coordinates of the tilt point using a triangulation algorithm. When a tilted lattice column is detected, the control module controls the drive assembly 33 to move according to the coordinates of the tilt point, causing the annular plate 34 to move up and down along the lattice column to the target position. Then, the first electric telescopic rod 35 is extended, driving the first drive plate 36 to contact the surface of the lattice column, and the tilt of the lattice column is corrected by applying thrust. During the correction process, the control module receives sensor data in real time until the lattice column returns to a vertical state, then controls the electric telescopic rod to retract, and the drive assembly 33 drives the annular plate 34 to reset. To avoid cable tangling, the cable is wound up and down using a cable reel. Using this technical solution, the present invention sets up a fixed base and an automatic adjustment system, using the base 31 and the receiving cavity 32 to fix the giant lattice column. Multiple sets of tilt sensors monitor the tilt state in real time, and the control module determines the tilt point using a triangulation algorithm, directing the telescopic mechanism to move the annular plate 34, so that the first electric telescopic rod 35 drives the first drive plate 36 for targeted correction.This closed-loop system automatically adjusts, reduces manual maintenance, ensures the verticality of the lattice columns, avoids uneven load distribution, extends the lifespan of the frame, and improves environmental adaptability and reliability.

[0053] According to another embodiment of the present invention, there are eight first drive plates 36, corresponding to the four sides and four vertical edges of the giant lattice column 2, respectively. The first drive plates 36 can be made of No. 45 steel plates, and rubber pads can be attached to their surfaces. The thickness of the rubber pads can be 5mm to 10mm to increase friction and prevent damage to the surface of the lattice column. Of the eight first drive plates 36, four drive plates corresponding to the sides are respectively installed inside the annular plate 34 at positions opposite to the four sides of the lattice column, and the other four drive plates corresponding to the vertical edges are respectively installed inside the annular plate 34 at positions opposite to the four edges of the lattice column. Each first drive plate 36 is connected to the end of a set of first electric telescopic rods 35. Using this technical solution, the present invention can effectively improve the accuracy and efficiency of correction, ensuring that the lattice column can quickly return to a vertical state.

[0054] According to another embodiment of the present invention, multiple sets of tilt sensors are spaced apart along the extension direction of the giant lattice column 2. The tilt sensors are located inside the giant lattice column 2 so that the first drive plate 36 can act on the giant lattice column 2. Multiple sensors in each set are located on the same horizontal plane, and the sensors can be fixed inside the giant lattice column 2 by brackets (bolted connections). Using this technical solution, the spaced arrangement of multiple sets of sensors can comprehensively monitor the tilt of the lattice column at different heights, enabling the control module to accurately determine the tilt position.

[0055] According to another embodiment of the present invention, the annular plate 34 is a hollow structure with an open top. Multiple telescopic motors 37 (the telescopic motors 37 extend vertically) are provided inside the annular plate 34. The ends of the multiple telescopic motors 37 are connected to an annular auxiliary plate 38. Multiple sets of second electric telescopic rods 39 are provided on the upper part of the auxiliary plate 38. Each set of second electric telescopic rods 39 is connected to a second drive plate 40 (the extension direction of the second electric telescopic rods 39 is horizontal, and the second drive plate 40 is vertically positioned). The multiple second drive plates 40 are arranged in a one-to-one correspondence with multiple first drive plates 36. When the telescopic motors 37 are retracted to their shortest length, the distance between the second drive plate 40 and its corresponding first drive plate 36 is 1-2 mm. Using this technical solution, the present invention expands the range of motion of the drive plate by moving the auxiliary plate 38 up and down through the telescopic motors 37, enabling the fixing seat to correct the tilt of the lattice column at different heights, thus improving the applicability and correction capability of the fixing seat.

[0056] According to another embodiment of the present invention, when the control module performs tilt correction, if multiple tilt sensors simultaneously detect tilt signals, the following steps are performed:

[0057] Step 1: Identify tilt sensors that are spatially continuous and have the same tilt direction as belonging to the same associated region;

[0058] Step 2: For the associated area, synchronously drive all the first electric telescopic rods 35 corresponding to that area to move in coordination;

[0059] For independent tilt points that are not associated, adjust them one by one from bottom to top: when adjusting the lower tilt point, collect sensor data of the already adjusted points above in real time, and dynamically correct the current adjustment amount through a pre-compensation algorithm;

[0060] Step 3: Repeat Step 2 until the overall tilt of the giant lattice column 2 returns to the preset vertical range. When the vertical span of the associated area is greater than the coverage height of the single-layer annular plate 34, the control module executes: drive the auxiliary plate 38 to rise to the top of the associated area via the telescopic motor 37, so that the second drive plate 40 covers the upper half of the associated area, while the first drive plate 36 remains covering the lower half of the associated area; pre-compensation algorithm (problem: the lattice column is a whole, and when correcting the lower part, it may slightly affect the already adjusted part above; solution: the control module has a simple prediction model inside. When driving a correction point below, it will predict in advance the possible impact of this operation on the upper structure; execution: the system will offset (compensate) the effect of this prediction in advance. For example, when correcting the lower part, the upper force application mechanism will be finely adjusted simultaneously to ensure that the upper corrected part remains stable; this allows the system to intelligently correct point by point from bottom to top, without the repeated situation of "adjusting the top, then the bottom is crooked again", which greatly improves the correction efficiency and stability). By adopting this technical solution, this correction method can avoid mutual interference between different tilt points, improve the efficiency and accuracy of correction, and ensure that the lattice column can stably return to a vertical state.

[0061] According to another embodiment of the present invention, the control module further includes a sensor self-diagnosis unit and a redundancy compensation unit;

[0062] The sensor self-diagnostic unit is used to periodically perform self-test operations on each group of tilt sensors, including zero-point drift calibration and signal continuity detection;

[0063] When the redundancy compensation unit detects a fault in any tilt sensor, it automatically ignores the sensor data and generates compensation data based on the tilt vector data of adjacent sensors through an interpolation algorithm.

[0064] The control module prioritizes using compensated data to execute triangulation algorithms and correction control until the faulty sensor is repaired or replaced. The self-test cycle can be once every 24 hours; the allowable error for zero-point drift calibration is ±0.05°, and calibration is performed if this error is exceeded; in signal continuity detection, if no sensor signal is received for three consecutive times, it is considered a signal interruption. The interpolation algorithm can be a linear interpolation algorithm, calculated based on data from two adjacent sets of sensors above and below the faulty sensor. The sensor self-diagnosis unit and redundancy compensation unit can be implemented through software programs within the control module, working in conjunction with the main control program. Every 24 hours, the sensor self-diagnosis unit initiates a self-test program, sending a zero-point calibration command to each set of tilt sensors. The sensor returns its current zero-point offset value; if the offset exceeds ±0.05°, the self-diagnosis unit sends a calibration signal, causing the sensor to automatically correct its zero point. Simultaneously, the self-diagnosis unit detects signal transmission with the sensor; if no signal is received for three consecutive times, the sensor is deemed faulty, and the fault information is sent to the redundancy compensation unit. Upon receiving a fault message, the redundancy compensation unit immediately ignores the data from the faulty sensor and retrieves the tilt vector data from the two adjacent normal sensors. It then calculates the compensation data for the faulty sensor's position using a linear interpolation algorithm and transmits the compensation data to the main program of the control module. The control module uses the compensation data for triangulation and correction control, ensuring normal tilt detection and correction even when a sensor fails, until the faulty sensor is repaired or replaced. The triangulation algorithm (principle: each tilt sensor measures the tilt angle and direction at its location. The control module aggregates data from all sensors and calculates: the system compares and fuses sensor data from different heights and directions. Through geometric triangulation, the tilt angle is converted into a specific offset of the lattice column at a particular height (e.g., at a height of 10 meters, the column shifts 5 centimeters eastward), outputting the final calculated precise position (height) and direction for which a correction force needs to be applied). By employing this technical solution, the present invention improves the reliability and fault tolerance of the sensor system by setting up a sensor self-diagnosis unit and a redundancy compensation unit, ensuring the long-term stable operation of the mounting base.

[0065] According to another embodiment of the present invention, a pressure sensor array is integrated on the first drive board 36, and the control module further includes a force feedback controller;

[0066] The pressure sensor array monitors the pressure distribution data of the contact surface between the first drive plate 36 and the giant lattice column 2 in real time. The force feedback controller dynamically calculates the optimal force application curve based on the pressure distribution data and adjusts the stroke speed and output force of the electric telescopic rod in real time through the PID algorithm.

[0067] When the pressure data exceeds a preset safety threshold, the force feedback controller immediately pauses the calibration operation and triggers an alarm. The pressure sensor array can consist of 4 to 8 pressure sensors, evenly distributed on the contact surface of the first drive plate 36. The measurement range of the pressure sensors is selected based on the actual height of the giant lattice column 2. The preset safety threshold can be 30kN to 40kN (the specific safety threshold range is not limited to 30kN to 40kN, but is specifically set according to the column height of the giant lattice column 2). The proportional coefficient of the PID algorithm can be 0.5 to 1.5, the integral time can be 0.1 to 1 second, and the derivative time can be 0.01 to 0.1 seconds. The pressure sensors can be strain gauge type pressure sensors. The pressure sensor array is attached to the surface of the first drive plate 36 in contact with the lattice column. Using this technical solution, when the pressure value detected by a pressure sensor exceeds the preset safety threshold, the force feedback controller immediately sends a signal to the main controller to pause the operation of the electric telescopic rod and trigger the alarm indicator light and buzzer on the control cabinet to remind personnel to check. Pressure monitoring and force feedback control can prevent damage to the lattice columns due to excessive force during the calibration process, thus improving the safety of the calibration operation.

[0068] According to another embodiment of the present invention, it further includes an early warning module;

[0069] The control module is preset with a first tilt threshold θ1 and a second tilt threshold θ2. When any tilt sensor detects a real-time tilt angle θ of θ1≤θ≤θ2, the control module activates the early warning module, issues an audible and visual alarm, and records the tilt position. When the real-time tilt angle θ>θ2, an emergency stop alarm is triggered, and a structural safety alarm is sent to the remote monitoring terminal. Specifically, the first tilt threshold θ1 can be 0.5°, and the second tilt threshold θ2 can be 2° (the first and second tilt thresholds are not limited to 0.5° and 2°, but are set according to the specific application scenario of the modular splicing mega-frame column, the height of the mega-lattice column, and construction requirements). When the control module performs tilt monitoring, it applies a time window filter to the real-time tilt angle data. When any tilt sensor detects θ satisfying θ1≤θ≤θ2, the early warning module is triggered only after the duration exceeds T1 (T1 can be 10 minutes). When the real-time tilt angle θ>θ2 or three consecutive sensors in the associated area simultaneously exceed θ1, an emergency stop operation is performed only after the duration exceeds T2 (T2 can be 3 minutes). Using this technical solution, staff can promptly check the status of the lattice columns after receiving an early warning; upon receiving an emergency alarm, they can immediately take emergency measures to prevent safety accidents.

A modular, assembled mega-frame structure, characterized in that: include: Multiple giant lattice columns and multiple giant truss beams used to connect the tops of the multiple giant lattice columns in sequence; Both the giant lattice column and the giant truss beam are assembled from multiple modular units. Each modular unit includes four chords, planar straight web members for sequentially connecting the two ends of the four chords, and eight spatial web members. One end of each of the eight spatial web members is connected to a chord, and the other end is connected to a chord. In the modular unit of the giant lattice column, the chords are vertically arranged, and in the modular unit of the giant truss beam, the chords are horizontally arranged. In each module unit, one end of the chord is internally welded with a first connecting pipe with internal threads, and the other end is internally welded with a second connecting pipe with internal threads. A threaded steel rod is screwed into the second connecting pipe. The threaded steel rod of one module unit in any two adjacent module units is screwed into the first connecting pipe of the other module unit to connect the two adjacent module units. Each mega-lattice column is provided with a corresponding fixing base to secure the mega-lattice column. The fixing base includes: A base for connecting to the mounting foundation, the base having a receiving cavity for accommodating the bottom end of the giant lattice column; Multiple sets of tilt sensors, with multiple tilt sensors in each set spaced circumferentially along the giant lattice column; The telescopic mechanism includes multiple drive components mounted on the base, and a common annular plate on the multiple drive components. Multiple sets of first electric telescopic rods are provided inside the annular plate. Each set of first electric telescopic rods is connected to a first drive plate. The first drive plate can move up and down along the giant lattice column under the action of the drive components. When it is necessary to adjust the lattice column, the first electric telescopic rod drives the first drive plate to contact the giant lattice column. The control module is connected to multiple sets of tilt sensors, multiple drive components, and multiple first electric telescopic rods. The control module can receive tilt vector data from each set of tilt sensors and calculate the coordinates of the tilt point through a triangulation algorithm. When a tilt signal is detected, the control module controls multiple drive components to drive the annular plate to move to the target position according to the coordinates of the tilt point, and drives the first drive plate to move toward the giant lattice column through the first electric telescopic rod. In each module unit, a planar diagonal brace connects two adjacent chord members, and two diagonal braces connect any two adjacent giant lattice columns, with the two diagonal braces arranged in a cross configuration.

2. The modular assembly mega-frame structure as described in claim 1, characterized in that, There are eight first drive plates, which correspond to the four sides and four vertical edges of the giant lattice column, respectively.

3. The modular assembly mega-frame structure as described in claim 2, characterized in that, Multiple tilt sensors are spaced apart along the extension direction of the giant lattice column, and the tilt sensors are located inside the giant lattice column so that the first drive plate can act on the giant lattice column.

4. The modular assembly mega-frame structure as described in claim 3, characterized in that, The annular plate has a hollow structure and an open top. Multiple telescopic motors are installed inside the annular plate. The ends of the multiple telescopic motors are connected to an annular auxiliary plate.

The multiple second drive plates are arranged in a one-to-one correspondence with multiple first drive plates.

5. The modular assembly mega-frame structure as described in claim 4, characterized in that, When the control module performs tilt correction, if multiple tilt sensors detect tilt signals simultaneously, the following steps are executed: Step 1: Identify tilt sensors that are spatially continuous and have the same tilt direction as belonging to the same associated region; Step 2: For the associated area, synchronously drive all the first electric telescopic poles corresponding to the associated area to move in coordination; For independent tilt points that are not associated, adjust them one by one from bottom to top: when adjusting the lower tilt point, collect the tilt sensor data of the upper adjusted point in real time, and dynamically correct the current adjustment amount through the pre-compensation algorithm; Step 3: Repeat step 2 until the overall tilt of the giant lattice column returns to the preset vertical range.

6. The modular assembly mega-frame structure as described in claim 5, characterized in that, The control module also includes a sensor self-diagnosis unit and a redundancy compensation unit; The sensor self-diagnostic unit is used to periodically perform self-test operations on each group of tilt sensors, including zero-point drift calibration and signal continuity detection; When the redundancy compensation unit detects a fault in any tilt sensor, it automatically ignores the data of that tilt sensor and generates compensation data based on the tilt vector data of the adjacent tilt sensors through an interpolation algorithm. The control module prioritizes using the compensation data to execute the triangulation algorithm and correction control until the faulty tilt sensor is repaired or replaced.

7. The modular assembly mega-frame structure as described in claim 6, characterized in that, The first driver board integrates a pressure sensor array, and the control module also includes a force feedback controller; The pressure sensor array monitors the pressure distribution data of the contact surface between the first drive plate and the giant lattice column in real time. The force feedback controller dynamically calculates the optimal force application curve based on the pressure distribution data and adjusts the stroke speed and output force of the electric telescopic rod in real time through the PID algorithm. When the pressure data exceeds the preset safety threshold, the force feedback controller immediately suspends the calibration operation and triggers an alarm.

8. The modular assembly mega-frame structure as described in claim 6, characterized in that, It also includes an early warning module; The control module is preset with a first tilt threshold θ1 and a second tilt threshold θ2. When any tilt sensor detects a real-time tilt angle θ of θ1≤θ≤θ2, the control module activates the early warning module, issues an audible and visual alarm and records the tilt position. When the real-time tilt angle θ>θ2, it triggers an emergency stop alarm and sends a structural safety alarm to the remote monitoring terminal.
