Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more particularly to a method and device for monitoring and lifting a large slipform construction platform. Background Technology

[0002] Large slipform construction platforms are widely used in continuous pouring projects such as shallow circular silos, high bridge piers, and concrete cable towers. They typically consist of a formwork system, an operating platform, and a lifting system. The slipform platform is gradually raised through the cyclical movement of pre-embedded support rods and jacks. Existing slipform lifting equipment mostly uses traditional hydraulic jacks. During the lifting process, there is a lack of real-time monitoring and effective control of the synchronization of lifting height and stress state at each lifting point. Furthermore, the attitude deviation of the constructed structure mainly relies on manual measurement, making it difficult to detect and correct deviations in a timely manner, resulting in insufficient safety and construction quality control. Summary of the Invention

[0003] The purpose of this invention is to provide a lifting monitoring method and lifting device for a large slipform construction platform that can achieve synchronous lifting and stress monitoring.

[0004] This invention is achieved through the following measures: A method for monitoring and lifting a large slipform construction platform, characterized by the following steps: S1. n sets of support rods are implanted in the constructed structure silo. n sets of gantry column structures are set up on the slipform construction platform, and electric servo jacks are installed on the gantry column structures, allowing the support rods to pass through the interior of each electric servo jack. A slipform lifting main controller and multiple distributed unit controllers are set up on the slipform construction platform, and tilt sensors and vertical height monitoring sensors are arranged. Concrete strength monitoring data is connected to the slipform lifting main controller. The concrete strength monitoring data is strength assessment data obtained based on concrete temperature and humidity monitoring data. The slipform construction platform is a sliding formwork construction platform system used for concrete pouring and shaping, and gradually lifted along the support rods as construction progresses. In a specific embodiment, the slipform construction platform specifically includes a slipform frame, a steel pipe platform frame, an inner operating platform, an outer operating platform, and a sliding formwork. S2. Before lifting, detect the fixed load of each electric servo jack and set the detected fixed load as the reference force of the corresponding electric servo jack. At the same time, obtain the initial displacement of each electric servo jack, the initial posture of the slipform construction platform and the initial lifting height. S3. Control the lower locking mechanism to lock the support rod, control the upper locking mechanism to press the release port to disengage the upper locking mechanism from the support rod, drive the electric servo jack to extend to the predetermined stroke position and then close the release port of the upper locking mechanism. S4. Control the upper locking mechanism to lock the support rod, control the lower locking mechanism to press the release port to make the lower locking mechanism disengage from the support rod, drive the electric servo jack to retract synchronously, and drive the sliding formwork construction platform to lift synchronously through the sensor seat of the fixed tension sensor. S5. During the synchronous retraction and lifting process, the lifting displacement and lifting force of each electric servo jack are collected in real time, and the collected data is transmitted to the sliding form lifting main controller via the distributed unit controller. The sliding form lifting main controller performs closed-loop synchronous control of displacement based on the lifting displacement of each electric servo jack, and adjusts the driving force of the corresponding electric servo jack according to the lifting force of each electric servo jack, so as to keep the force on each lifting point balanced and realize the closed-loop control of displacement and force during the lifting process. S6. Collect data from the tilt sensor and vertical height monitoring sensor in real time to monitor the lifting posture of the slipform construction platform, and perform synchronous correction control when the posture deviation exceeds the limit, while triggering a posture deviation warning. S7. After completing one lifting stroke, repeat steps S3 to S6; and determine whether the conditions for the next stage of lifting construction are met based on the accessed concrete strength monitoring data. If the conditions are met, proceed to the next lifting cycle; if the conditions are not met, issue an early warning or stop the lifting.

[0005] The invention also has the following specific features: The electric servo jack is equipped with a displacement detection unit, which is used to detect the extension and retraction displacement of the corresponding electric servo jack in real time and transmit the displacement data to the distributed unit controller; the sliding form lifting main controller performs closed-loop synchronous control of displacement based on the displacement data of each electric servo jack. The distributed unit controller is used to drive and control multiple electric servo jacks to lift synchronously, and to synchronously collect the lifting displacement and lifting force of the corresponding electric servo jacks; the sliding form lifting main controller is connected to each distributed unit controller through an industrial Ethernet bus.

[0006] The slipform lifting main controller is equipped with a data interface to receive concrete strength monitoring data, silo posture monitoring data, and lifting height monitoring data, and monitors them in the industrial control software as an early warning basis for the synchronous lifting process. The slipform lifting main controller is connected to the user's cloud-based smart construction platform via a wireless network to achieve remote monitoring of the overall lifting process of the slipform construction platform.

[0007] The synchronous correction control in step S6 is as follows: based on the tilt angle data collected by the tilt angle sensor and the lifting height data collected by the vertical height monitoring sensor, the attitude deviation of the slipform construction platform is determined, and the slipform construction platform is corrected in real time by adjusting the driving force or displacement of the corresponding electric servo jack.

[0008] The lifting device based on the monitoring method includes a support rod embedded in the concrete of the structure to be constructed, an electric servo jack around the support rod, a gantry column structure under the electric servo jack, and a sliding formwork on the slipform construction platform under the gantry column structure.

[0009] The electric servo jack includes a base, a jack cylinder is provided on the upper side of the base, a jack piston rod and a hollow ball screw pair are provided in the jack cylinder, the jack piston rod is a hollow structure and is sleeved on the periphery of the support rod, the hollow ball screw pair cooperates with the jack piston rod, an upper locking mechanism is screwed to the upper end of the jack piston rod, the upper locking mechanism and the jack piston rod perform lifting movements together, a lower locking mechanism is provided on the lower side of the base, and both the lower locking mechanism and the upper locking mechanism are sleeved on the periphery of the support rod; A drive mechanism is also provided on the upper side of the base. A corresponding motion conversion device is connected to the drive mechanism. The drive mechanism includes a servo motor and a reducer. The reducer is connected to the servo motor to increase the torque, thereby realizing the large tonnage lifting force of the electric servo jack. The motion conversion device includes a small synchronous pulley, a large synchronous pulley, and a synchronous belt. The small synchronous pulley and the large synchronous pulley are connected by the synchronous belt. The large synchronous pulley is connected to the hollow ball screw pair. The drive mechanism drives the small synchronous pulley, which in turn drives the large synchronous pulley to move through the transmission of the synchronous belt. The large synchronous pulley drives the hollow ball screw pair, which in turn drives the jack piston rod to perform up and down lifting motion.

[0010] Both the upper locking mechanism and the lower locking mechanism include an outer component and an inner component, with the inner component disposed inside the outer component; The outer components of the upper locking mechanism include an upper locking cylinder body and an upper locking flange sleeved around the support rod. The upper locking flange is bolted to the upper end of the upper locking cylinder body. The upper locking cylinder body is screwed to the upper end of the jack piston rod through an external thread on its outer side. That is, the inner wall surface of the jack piston rod near the upper end is provided with an internal thread that mates with the external thread. The outer components of the lower locking mechanism include a lower locking flange sleeved around the support rod. The lower locking flange is bolted to the base. A lower locking cylinder is bolted to the lower side of the lower locking flange. A tension sensor device sleeved around the support rod is bolted to the lower end of the lower locking cylinder. The tension sensor device includes a tension sensor and a sensor base. The lower end of the sensor base is bolted to the gantry column structure. Both the upper locking cylinder and the lower locking cylinder are provided with a locking port; The internal components of the upper locking mechanism include a conical base with a conical inner hole, which is disposed in the upper locking cylinder and sleeved around the support rod. A locking block with a conical structure that matches and is sleeved around the support rod is disposed in the conical base. Several internal teeth that cooperate with the support rod are provided on the inner wall of the locking block. A butterfly spring that is sleeved around the support rod is disposed between the locking block and the upper locking flange. The locking block is always pressed against the conical base by the force of the butterfly spring, so that the internal teeth of the locking block hold the support rod tightly. A release piston is disposed between the conical base and the upper locking cylinder. An upper sealing ring and a lower sealing ring are installed in the inner hole of the release piston. The internal components of the lower locking mechanism are the same as those of the upper locking mechanism; When it is necessary to loosen the upper or lower locking mechanism, air or oil pressure is injected into the loosening port to push out the loosening piston, which drives the locking block to overcome the disc spring and disengage from the conical base, causing the inner hole of the locking block to loosen, thereby allowing the support rod to disengage from the locking block. When there is no external pressure in the loosening port, the upper or lower locking mechanism automatically locks onto the support rod, thereby achieving continuous and synchronous lifting of the sliding template by controlling the upper and lower loosening ports and controlling the extension and retraction of the electric servo jack.

[0011] The gantry column structure includes a horizontally arranged base plate, with an inner vertical plate and an outer vertical plate on both sides of the base plate. The base plate and the two vertical plates form a gantry structure. The sensor seat is fixed on the upper side of the base plate. Obviously, the base plate is sleeved around the support rod. Sliding templates are fixed on the inner and outer vertical plates respectively.

[0012] The base plate has four sets of through holes piercing through both ends of the base plate. Each inner and outer vertical plate has a pair of round rods that mate with the through holes 1. The four sets of round rods pass through the corresponding through holes 1 in an alternating manner. Each inner and outer vertical plate has a pair of through holes 2. The pair of through holes 2 on the inner vertical plate interlocks with the pair of round rods on the outer vertical plate, and vice versa. This allows for a wide range of adjustment of the distance between the inner and outer vertical plates, thereby adjusting the distance between the two sliding templates to meet the engineering needs of various concrete thicknesses.

[0013] On both sides of the base plate, there is a pair of limiting bolts provided by a threaded structure. The four sets of limiting bolts are respectively inserted into the two outermost through holes of the four sets of through holes. The round rods in the two outermost through holes are provided with several sets of insertion holes that cooperate with the limiting bolts. The inner end of the limiting bolt is set in the corresponding insertion hole. The purpose of providing two sets of limiting bolts on one side is to enhance the locking strength. The outer end of the limiting bolt is provided with a handle. After adjusting the distance between the two sliding templates, rotating the handle will insert the inner end of the limiting bolt into the corresponding insertion hole, thereby locking and fixing the round rod, and thus fixing the two sliding templates.

[0014] The lifting device operates as follows: the lower locking mechanism locks the support rod, the upper locking mechanism's release port is opened by hydraulic or pneumatic pressure, the electric servo jack extends to its full stroke limit, and the upper locking mechanism's release port is closed; then the upper locking mechanism locks the support rod, the lower locking mechanism's release buckle is released by pressure, and the electric servo jack retracts synchronously, thereby driving the sliding template or sliding formwork platform to lift synchronously via the sensor base. After lifting one stroke to the desired position, the lower locking mechanism locks the support rod, the upper locking mechanism's release port is released by pressure, the electric servo jack extends to its full stroke limit, and the upper locking mechanism's release port is closed; then the upper locking mechanism locks the support rod, the lower locking mechanism's release buckle is released by pressure, and the electric servo jack retracts synchronously, thereby driving the sliding formwork platform to lift synchronously in a cyclical manner via the sensor base.

[0015] The beneficial effects of the present invention are as follows: By setting up an electric servo jack, a slipform lifting main controller and a distributed unit controller on the slipform construction platform, and combining the monitoring of lifting displacement, lifting force, tilt angle and vertical height, the present invention realizes synchronous control, force balance monitoring, attitude monitoring and real-time correction and early warning of the lifting process of the slipform construction platform.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0030] Example 1 See Figure 1-5 A method for monitoring and lifting a large slipform construction platform includes the following steps: S1. Insert n sets of support rods 115 into the constructed structure silo, set n sets of gantry column structures on the slipform construction platform, and install electric servo jacks 100 on the gantry column structures so that the support rods 115 pass through the inside of each electric servo jack 100; set up a slipform lifting main controller and multiple distributed unit controllers on the slipform construction platform, and arrange tilt sensors and vertical height monitoring sensors, and connect the concrete strength monitoring data to the slipform lifting main controller. The concrete strength monitoring data is the strength assessment data obtained based on the concrete temperature and humidity monitoring data. In this embodiment, the structural silo is a shallow circular silo 121, and the slipform construction platform is a sliding formwork construction platform system used for concrete pouring and shaping and gradually raised along the support rods as the construction progresses. In this embodiment, the slipform construction platform specifically includes several sets of slipform frames 116, several sets of steel pipe platform frames 117, an inner operating platform 118, an outer operating platform 120, and two sets of sliding formwork 119. Specifically, the two sets of sliding formwork 119 are coaxially arranged ring structures and are fixedly connected to n sets of gantry column structures. Several sets of sliding formwork frames 116 are set on the outer side of the two sets of sliding formwork 119. Steel pipe platform frames 117 are set on the sliding formwork frames 116. The inner operating platform 118 and the outer operating platform 120 are respectively set on several steel pipe platform frames 117 on the inner and outer sides for workers to carry out construction operations, such as tying steel bars and pouring concrete. The sliding formwork frames 116 and the steel pipe platform frames 117 are both composed of several rods to form a triangular support reinforcement structure to support the inner operating platform 118 and the outer operating platform 120.

[0031] S2. Before lifting, detect the fixed load of each electric servo jack 100 and set the detected fixed load as the reference force of the corresponding electric servo jack 100. At the same time, obtain the initial displacement of each electric servo jack 100, the initial posture of the slipform construction platform and the initial lifting height. S3. Control the lower locking mechanism to lock the support rod 115, control the upper locking mechanism to press the release port to disengage the upper locking mechanism from the support rod 115, drive the electric servo jack 100 to extend to the predetermined stroke position and then close the release port of the upper locking mechanism. S4. Control the upper locking mechanism to lock the support rod 115, control the lower locking mechanism to press the release port to make the lower locking mechanism disengage from the support rod 115, drive the electric servo jack 100 to retract synchronously, and drive the sliding formwork construction platform to lift synchronously through the sensor seat of the fixed tension sensor. S5. During the synchronous retraction and lifting process, the lifting displacement and lifting force of each electric servo jack 100 are collected in real time, and the collected data is transmitted to the sliding form lifting main controller via the distributed unit controller. The sliding form lifting main controller performs closed-loop synchronous control of displacement based on the lifting displacement of each electric servo jack 100, and adjusts the driving force of the corresponding electric servo jack 100 according to the lifting force of each electric servo jack 100, so as to keep the force on each lifting point balanced and realize the closed-loop control of displacement and force during the lifting process. S6. Real-time acquisition of data from tilt sensors and vertical height monitoring sensors to monitor the lifting posture of the slipform construction platform, and synchronous correction control when the posture deviation exceeds the limit, while triggering a posture deviation warning. S7. After completing one lifting stroke, repeat steps S3 to S6; and determine whether the conditions for the next stage of lifting construction are met based on the accessed concrete strength monitoring data. If the conditions are met, proceed to the next lifting cycle; if the conditions are not met, issue an early warning or stop the lifting.

[0032] The electric servo jack 100 is equipped with a displacement detection unit, which is used to detect the extension and retraction displacement of the corresponding electric servo jack 100 in real time and transmit the displacement data to the distributed unit controller; the sliding form lifting main controller performs closed-loop synchronous control of displacement based on the displacement data of each electric servo jack. The distributed unit controller is used to drive and control multiple electric servo jacks 100 to lift synchronously, and to synchronously collect the lifting displacement and lifting force of the corresponding electric servo jacks 100; the sliding form lifting main controller communicates with each distributed unit controller through an industrial Ethernet bus.

[0033] The slipform lifting main controller is equipped with a data interface to receive concrete strength monitoring data, silo posture monitoring data, and lifting height monitoring data, and monitors them in the industrial control software as an early warning basis for the synchronous lifting process; The slipform lifting main controller connects to the user's cloud-based smart construction platform via a wireless network to enable remote monitoring of the entire lifting process of the slipform construction platform.

[0034] The synchronous correction control in step S6 is as follows: based on the tilt angle data collected by the tilt angle sensor and the lifting height data collected by the vertical height monitoring sensor, the attitude deviation of the slipform construction platform is determined, and the slipform construction platform is corrected in real time by adjusting the driving force or displacement of the corresponding electric servo jack 100.

[0035] Furthermore, such as Figure 4 and Figure 5 As shown, in the large slipform construction platform lifting and monitoring method of the present invention, the control system uses a PLC control module as the control core. The PLC control module includes an operational controller, an instruction signal generator, and a data acquisition interface. The operational controller corresponds to the operational control function of the aforementioned slipform lifting main controller, and the data acquisition interface is used to receive various monitoring feedback signals during the lifting process.

[0036] During operation, the command signal generator first issues a lifting control command. This command is compared with the feedback signal from the displacement sensor at the preceding comparison node to generate a displacement deviation signal. This displacement deviation signal then enters the position adjustment stage to adjust and control the lifting displacement of each electric servo jack. This process corresponds to the closed-loop synchronous control of displacement based on the lifting displacement of each electric servo jack in the aforementioned method.

[0037] The control signal after position adjustment is compared with the speed feedback signal and then enters the speed adjustment stage to adjust the dynamic response during the lifting process. Figure 5In this system, the speed feedback is generated by differential adjustment of the absolute position sliding screen feedback signal, and together with the displacement sensor feedback, it forms the motion state feedback path during the lifting process. Through position and speed adjustment, the synchronous lifting process of each electric servo jack can be continuously controlled, improving the smoothness and synchronization of the lifting process.

[0038] After speed adjustment, the control signal is further compared with the force feedback signal, which is provided by the force sensor feedback branch. Specifically, the force sensor installed on the electric servo jack collects the lifting force signal of the corresponding lifting point in real time. The lifting force signal is processed by the force sensor acquisition filter to form the force sensor feedback, which is then fed back to the control link. The arithmetic controller adjusts the driving force of the corresponding electric servo jack according to the lifting force of each electric servo jack to keep the force on each lifting point balanced, thereby realizing closed-loop force control during the lifting process. Thus, the control link together constitutes the displacement and force closed-loop control in the aforementioned method.

[0039] After the above comparison and adjustment, the control signal is input to the servo driver after passing through a gain circuit. The servo driver then drives the servo motor. The servo motor further drives the servo motor reducer, motion conversion device, hollow ball screw pair, and jack piston rod in the electric servo jack, enabling the electric servo jack to extend and retract. In conjunction with the upper and lower locking mechanisms, the support rod is alternately locked and unlocked, allowing the electric servo jack to lift upwards along the support rod, thereby synchronously lifting the slipform construction platform.

[0040] Meanwhile, concrete strength feedback, slipform posture feedback, and cumulative lifting height feedback are all connected to the data acquisition interface in the PLC control module. Specifically, the concrete strength feedback corresponds to the aforementioned concrete strength monitoring data, used to determine whether the conditions for the next stage of lifting construction are met; the slipform posture feedback corresponds to the aforementioned slipform posture monitoring data, and is linked with data collected by tilt sensors and vertical height monitoring sensors, used to monitor the lifting posture of the slipform construction platform, and to execute synchronous correction control when posture deviation exceeds limits, while triggering a posture deviation warning; the cumulative lifting height feedback corresponds to the aforementioned lifting height monitoring data, used to monitor and record the cumulative lifting process of the slipform construction platform.

[0041] In summary, this invention uses a PLC control module to uniformly collect, calculate, and control feedback from displacement sensors, tension sensors, concrete strength, silo posture, and cumulative lifting height, forming a closed-loop monitoring system for the synchronous lifting process of the electric servo jack. This enables the slipform construction platform to monitor lifting displacement, lifting force, posture, synchronous correction, and stage construction determination during the lifting process.

The hollow ball screw pair 1024 cooperates with the jack piston rod 106. An upper locking mechanism 105 is screwed to the upper end of the jack piston rod 106. The upper locking mechanism 105 and the jack piston rod 106 perform lifting movements together. A lower locking mechanism 103 is provided on the lower side of the base. Both the lower locking mechanism 103 and the upper locking mechanism 105 are sleeved on the outside of the support rod 115. A drive mechanism 101 is also provided on the side of the base. A corresponding motion conversion device 102 is connected to the drive mechanism 101. The drive mechanism 101 includes a servo motor and a reducer. The reducer is connected to the servo motor and increases the torque through the reducer, thereby realizing the large tonnage lifting force of the electric servo jack 100. The motion conversion device 102 includes a small synchronous pulley 1021, a large synchronous pulley 1023, and a synchronous belt 1022. The small synchronous pulley 1021 and the large synchronous pulley 1023 are connected by the synchronous belt 1022. The large synchronous pulley 1023 is connected to the hollow ball screw pair 1024. The drive mechanism 101 drives the small synchronous pulley 1021, and drives the large synchronous pulley 1023 through the transmission of the synchronous belt 1022. The large synchronous pulley 1023 drives the hollow ball screw pair 1024, and the hollow ball screw pair 1024 drives the jack piston rod 106 to perform up and down lifting movements.

[0044] Both the upper locking mechanism 105 and the lower locking mechanism 103 include an outer component and an inner component, with the inner component located inside the outer component; The outer components of the upper locking mechanism 105 include an upper locking cylinder 1059 and an upper locking flange 1051 sleeved around the support rod 115.

The upper locking cylinder 1059 is screwed to the upper end of the jack piston rod 106 by an external thread on its outer side. That is, the inner wall surface of the jack piston rod 106 near the upper end is provided with an internal thread that mates with the external thread. The outer components of the lower locking mechanism 103 include a lower locking flange 1031 sleeved around the support rod 115. The lower locking flange 1031 is bolted to the base. A lower locking cylinder 1032 is bolted to the lower side of the lower locking flange 1031.

The tension sensor device 104 includes a tension sensor and a sensor base 108. The lower end of the sensor base is bolted to a gantry column structure 122. Both the upper locking cylinder 1059 and the lower locking cylinder 1032 are provided with a locking port 1058; The internal components of the upper locking mechanism 105 include a conical base 1057 with a conical inner hole, which is disposed inside the upper locking cylinder 1059 and sleeved around the support rod 115.

Several internal teeth that cooperate with the support rod 115 are provided on the inner wall of the locking block 1054. A butterfly spring 1052 sleeved around the support rod 115 is disposed between the locking block 1054 and the upper locking flange 1051. The locking block 1054 is always pressed against the conical base 1057 by the force of the butterfly spring 1052, so that the internal teeth of the locking block hold the support rod 115 tightly. A release piston 1053 is disposed between the conical base 1057 and the upper locking cylinder 1059. An upper sealing ring 1055 and a lower sealing ring 1056 are installed in the inner hole of the release piston 1053. The internal components of the lower locking mechanism 103 are the same as those of the upper locking mechanism 105; When it is necessary to loosen the upper locking mechanism 105 or the lower locking mechanism 103, air or oil pressure is injected into the loosening port 1058, which pushes out the loosening piston 1053, driving the locking block 1054 to overcome the disc spring 1052 and disengage from the conical base 1057, causing the inner hole of the locking block 1054 to loosen, thereby allowing the support rod 115 to disengage from the locking block; when there is no external pressure in the loosening port 1058, the upper locking mechanism 105 or the lower locking mechanism 103 automatically locks onto the support rod 115, thereby achieving continuous synchronous lifting of the sliding template by controlling the upper and lower loosening ports 1058 and controlling the extension and retraction of the electric servo jack 100.

An inner vertical plate 114 and an outer vertical plate 112 are respectively arranged on both sides of the base plate 109. The base plate 109 and the two inner and outer vertical plates form a gantry structure. The sensor seat 108 is fixed on the upper side of the base plate 109. Obviously, the base plate 109 is sleeved on the periphery of the support rod 115. Sliding templates 119 are fixed on the inner vertical plate 114 and the outer vertical plate 112 respectively.

[0046] The lifting device operates as follows: the lower locking mechanism 103 locks the support rod 115, the upper locking mechanism 105's release port 1058 is opened by hydraulic or pneumatic pressure, the electric servo jack 100 extends to its full stroke limit position, and the upper locking mechanism 105's release port 1058 is closed; then the upper locking mechanism 105 locks the support rod 115, the lower locking mechanism 103's release buckle 1058 is opened by pressure, the electric servo jack 100 is started to retract synchronously, thereby driving the sliding template or sliding formwork construction platform to lift synchronously through the sensor seat 108. After the lifting stroke is completed, the lower locking mechanism 103 is activated to lock the support rod 115, and the release port 1058 of the upper locking mechanism 105 is pressed open. The electric servo jack 100 extends to the full stroke limit position and closes the release port 1058 of the upper locking mechanism 105. Then, the upper locking mechanism 105 locks the support rod 115, the release buckle 1058 of the lower locking mechanism 103 is pressed open, and the electric servo jack 100 is activated to retract synchronously, thereby driving the slipform construction platform to synchronously and cyclically lift through the sensor seat 108.

[0047] Example 3 See Figure 6 The difference from Embodiment 2 is that four sets of through holes 1 through both ends of the bottom plate 109 of the gantry column structure 122 are arranged parallel to each other. A pair of round rods 110 that cooperate with the through holes 1 are provided on the inner side surfaces of the inner vertical plate 114 and the outer vertical plate 112. The four sets of round rods 110 pass through the corresponding through holes 1 in an alternating manner. A pair of through holes 2 111 are provided on both the inner vertical plate 114 and the outer vertical plate 112. The pair of through holes 2 111 on the inner vertical plate 114 interlocks with the pair of round rods 110 on the outer vertical plate 112. The pair of through holes 2 111 on the outer vertical plate 112 interlocks with the pair of round rods 110 on the inner vertical plate 114. This allows for a larger range of adjustment of the distance between the inner vertical plate 114 and the outer vertical plate 112, thereby allowing for adjustment of the distance between the two sliding templates 119 to meet the engineering needs of various concrete thicknesses.

[0048] On both sides of the base plate 109, there is a pair of limit bolts through a threaded structure. The four sets of limit bolts pass through the two outermost through holes of the four sets of through holes. The round rods 110 in the two outermost through holes are provided with several sets of insertion holes 113 that cooperate with the limit bolts. The inner end of the limit bolt is set in the corresponding insertion hole 113. The purpose of setting two sets of limit bolts on one side is to enhance the locking strength. The outer end of the limit bolt is provided with a handle. After adjusting the distance between the two sliding templates 119, the handle is turned so that the inner end of the limit bolt is inserted into the corresponding insertion hole 113, thereby locking and fixing the round rod 110, and thus fixing the two sliding templates 119.

Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
