Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering machinery and equipment, and in particular to a method for adjusting the self-adaptive horizontal precision of a cylinder formwork system. Background Art

[0002] During the construction of cylindrical structures such as elevator shafts, the corner formwork components of existing cylindrical formwork systems are coordinated with the side formwork components via a sliding rail and slider structure, allowing for smoother relative motion between the two components. This structure addresses the difficulties of traditional formwork systems, including difficult operation, long construction periods, and high labor consumption. However, the connection method between the formwork components and the frame used in existing cylindrical formwork systems cannot adapt to frame installation errors. Deviations in the frame installation position can prevent the formwork components from fully closing, or even prevent the frame from climbing. Furthermore, when the frame installation error exceeds ±3mm, manual adjustment is required, which is both time-consuming and labor-intensive. Summary of the Invention

[0003] Aiming at the problem that the existing cylindrical mold frame system has poor adaptability to the frame installation position error, which leads to the difficulty of mold closing, the present invention aims to provide a method for adjusting the horizontal precision of the cylindrical mold frame system.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a method for adjusting the adaptive horizontal precision of a cylindrical mold frame system, the steps of which are as follows: S1: The integral jacking steel platform jacks up the cylindrical formwork system to the current floor where the cylindrical structure is to be cast. The cylindrical formwork system at least includes a support frame, a side formwork assembly, a corner formwork assembly, a cantilever device, a detection device, an adjustment mechanism and a control unit. At least one pair of adjustment mechanisms are arranged at intervals along the horizontal direction on the inner side of each side formwork assembly. The adjustment mechanism includes a latch 1 and an electric telescopic rod. The two ends of the latch 1 are snapped between two ribs arranged vertically at intervals in the side formwork assembly. One end of the electric telescopic rod is sleeved on the latch 1, and the other end thereof is connected to the support frame. The detection device and the control unit are arranged on the support frame. The adjustment mechanism and the detection device are connected to the control unit by signal. S2: The detection device detects the horizontality of the support frame, and the control unit calculates whether the direction and value of the horizontal installation error of the support frame are within the allowable range. If the horizontal installation error exceeds the allowable range, the control unit controls the corresponding adjustment mechanism to extend and retract to correct the error until the direction and value of the horizontal installation error of the support frame are within the allowable range. This process is repeated until the cylindrical structure is cast layer by layer.

[0005] The method for adjusting the horizontal precision of the cylinder formwork system of the present invention is as follows: after the cylinder formwork system is lifted by the integral jacking steel platform to the current floor where the cylinder structure is to be cast, the detection device detects the horizontality of the support frame, and the control unit calculates whether the direction and value of the horizontal installation error of the support frame are within the allowable range. If the horizontal installation error exceeds the allowable range, the control unit controls the electric telescopic rod of the corresponding adjustment mechanism to extend and retract for correction, and the electric telescopic rod can rotate or move along the pin to perform fine position adjustment until the direction and value of the horizontal installation error of the support frame are within the allowable range; when the horizontal installation position of the support frame of the cylinder formwork system is within the allowable range of ±15m m, the horizontal installation position of the support frame is automatically adjusted through the adjustment mechanism, so that the cylindrical formwork system has the ability to adapt to installation errors, improves the operability of the cylindrical formwork system, reduces the difficulty of on-site construction, and improves construction efficiency. The time taken to adjust the horizontality of the cylindrical formwork system using this horizontal precision adjustment method is shortened from more than 3 hours to about 10 minutes; moreover, the horizontal installation position of the support frame is fine-tuned by remotely controlling the adjustment mechanism through the control unit, without adjusting the installation position of the overall jacking steel platform, thereby improving construction safety and ensuring the concrete pouring quality of the cylindrical structure.

[0006] Furthermore, in step S1, the two ribs of the side mold assembly are provided with corresponding holes, and the two ends of the transversely arranged pin of the adjustment mechanism are respectively inserted into the holes of the ribs on both sides and fixed, and the electric telescopic rod includes a connecting rod, a motor and a screw rod which are arranged and connected in sequence along the axis, and the end of the connecting rod is provided with a mounting hole, the pin one passes through the mounting hole at the end of the connecting rod, and the other end of the screw rod is connected to the support frame.

[0007] Furthermore, in step S1, the cylindrical formwork system also includes a second latch, which is arranged between two ribs of the side formwork assembly corresponding to the cantilever beam position of the cantilever device, and the two ribs are provided with corresponding holes. The two ends of the second latch are respectively inserted into the holes of the ribs on both sides and fixed, and the second latch passes through the end of the cantilever beam.

[0008] Furthermore, in step S1, at least one pair of adjustment mechanisms are symmetrically provided along the axis on each side mold assembly.

[0009] Furthermore, in step S1, the detection device includes a laser rangefinder and an inclination sensor. The laser rangefinder is used to measure the offset value between the axis of the support frame and the symmetry center of the cast cylindrical structure. The inclination sensor is used to monitor the inclination angle of the support frame. After the cylindrical formwork system is installed, the laser rangefinder and the inclination sensor are used to detect the horizontal installation error of the support frame. The allowable range of the error direction and value is within ±2mm. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. For ease of description, the terms "upper" and "lower" will be used in the following text in the same direction as in the accompanying drawings, but this does not constitute a limitation of the present invention.

[0013] The cylindrical formwork system of this embodiment comprises at least a support frame 11, a side formwork assembly 12, a corner formwork assembly 14, a cantilever device, a demoulding device, a detection device, an adjustment mechanism and a control unit. An integral jacking steel platform (not shown in the figure) is supported on the cast cylindrical structure 1. The support frame 11 of the cylindrical formwork system is vertically arranged and connected to the top of the integral jacking steel platform. The side formwork assembly 12 and the corner formwork assembly 14 are arranged between the cylindrical structure to be cast and the support frame 11, and the corner formwork assembly 14 is arranged at the corner portion of the cylindrical structure to be cast; multiple The cantilever device is arranged along the circumference of the support frame 11, and two cantilever devices are symmetrically arranged horizontally along the axis on each side of the support frame 11. One end of the cantilever beam 17 of the cantilever device is connected to the support frame 11, and the other end thereof is connected to the side mold assembly 12; a plurality of demoulding devices are arranged vertically and at intervals at the bottom of each cantilever device, and one end of the demoulding device is connected to the support frame 11, and the other end thereof is connected to the side mold assembly 12, so that the four side mold assemblies 12 enclosed on the outside of the support frame 11 are detachably connected to the support frame 11 through the cantilever device and the demoulding device.

[0014] The following combination Figures 1 to 3 The method for adjusting the self-adaptive horizontal precision of the cylindrical mold frame system of the present invention is described in detail as follows: S1: The overall jacking steel platform jacks the cylindrical formwork system to the current floor where the cylindrical structure is to be cast. The cylindrical formwork system at least includes a support frame 11, a side form assembly 12, a corner form assembly 14, a cantilever device, a detection device, an adjustment mechanism and a control unit. At least one pair of adjustment mechanisms are arranged at intervals along the horizontal direction on the inner side of each side form assembly 12. The adjustment mechanism includes a latch 15 and an electric telescopic rod 16. Both ends of the latch 15 are snapped between two ribs 121 vertically spaced apart on the side form assembly 12. One end of the electric telescopic rod 16 is sleeved on the latch 15, and the other end thereof is connected to the support frame 11. The detection device and the control unit are arranged on the support frame 11. The adjustment mechanism and the detection device are signal-connected to the control unit. S2: The detection device detects the horizontality of the support frame 11, and the control unit calculates whether the direction and value of the horizontal installation error of the support frame 11 are within the allowable range. If the horizontal installation error exceeds the allowable range, the control unit controls the corresponding adjustment mechanism to extend and retract to correct the error. The detection device monitors and feeds back the adjustment results in real time until the direction and value of the horizontal installation error of the support frame 11 are within the allowable range. This is repeated until the cylindrical structure is cast layer by layer. Figure 1 As shown, the cylindrical formwork system as a whole is biased toward the B side. The control unit controls the electric telescopic rod 16 of the adjustment mechanism on the A side to retract, and the electric telescopic rod 16 of the adjustment mechanism on the B side to extend, pushing the support frame 11 to move toward the A side for fine adjustment, thereby ensuring that the axis of the support frame 11 is in the center of the cast cylindrical structure 1.

[0015] The method for adjusting the horizontal precision of the cylinder formwork system of the present invention is as follows: after the cylinder formwork system is lifted by the integral jacking steel platform to the current floor of the cylinder structure to be cast, the detection device detects the horizontality of the support frame 11, and the control unit calculates whether the direction and value of the horizontal installation error of the support frame 11 are within the allowable range. If the horizontal installation error exceeds the allowable range, the control unit controls the electric telescopic rod 16 of the corresponding adjustment mechanism to extend and retract for correction, and the electric telescopic rod 16 can rotate or move along the latch 15 to perform fine position adjustment until the direction and value of the horizontal installation error of the support frame 11 are within the allowable range; if there is a horizontal installation error in the support frame 11 of the cylinder formwork system, the control unit controls the electric telescopic rod 16 of the corresponding adjustment mechanism to extend and retract for correction. Moreover, the electric telescopic rod 16 can rotate or move along the latch 15 to perform fine position adjustment until the direction and value of the horizontal installation error of the support frame 11 are within the allowable range; if there is a horizontal installation error in the support frame 11 of the cylinder formwork system, the control unit controls the electric telescopic rod 16 of the corresponding adjustment mechanism to extend and retract for correction. When the deviation is within ±15mm, the horizontal installation position of the support frame 11 is automatically adjusted through the adjustment mechanism, so that the cylindrical formwork system has the ability to adapt to the installation error, improves the operability of the cylindrical formwork system, reduces the difficulty of on-site construction, and improves construction efficiency. The time taken to adjust the horizontality of the cylindrical formwork system using this horizontal precision adjustment method is shortened from more than 3 hours to about 10 minutes; moreover, the horizontal installation position of the support frame 11 is fine-tuned by remotely controlling the adjustment mechanism through the control unit, and there is no need to adjust the installation position of the overall jacking steel platform, which improves the safety of construction and ensures the concrete pouring quality of the cylindrical structure.

[0016] like Figure 3 As shown, in the step S1, the two ribs 121 of the side mold assembly 12 are provided with corresponding holes, and the two ends of the transversely arranged pin 15 of the adjusting mechanism are respectively inserted into the holes of the ribs 121 on both sides and fixed, and the electric telescopic rod 16 includes a connecting rod 161, a motor 162 and a screw 163 which are arranged and connected in sequence along the axis, and a mounting hole is provided at the end of the connecting rod 161, and the pin 15 passes through the mounting hole at the end of the connecting rod 161, and the other end of the screw 163 is connected to the support frame 11, and the motor 162 drives the screw 163 to extend and retract to fine-tune the horizontal position of the support frame 11, and the electric telescopic rod 16 can rotate or move along the pin 15, so as to flexibly adjust the installation position of the support frame 11 for correction.

[0017] like Figure 3 As shown, in the step S1, the cylindrical formwork system also includes a second latch 18, which is arranged between two ribs 121 of the side formwork assembly 12 corresponding to the position of the cantilever beam 17 of the cantilever device. The two ribs 121 are provided with corresponding holes. The two ends of the second latch 18 are respectively inserted into the holes of the ribs 121 on both sides and fixed. The second latch 18 passes through the end of the cantilever beam 17, and the end of the cantilever beam 17 is connected to the side formwork assembly 12 through the second latch 18. The cantilever beam 17 can rotate or move along the second latch 18, so that it can cooperate with the fine adjustment of the horizontal position of the support frame 11.

[0018] like Figure 3 As shown, the net length of the first latch 15 and the second latch 18 in this embodiment is 50 mm, so that the electric telescopic rod 16 and the cantilever beam 17 can rotate or slide synchronously along the pin shaft; when there is an installation position deviation within ±15 mm in the template system, the horizontal installation position of the support frame 11 is adjusted by the adjustment mechanism to meet the need for fine-tuning between it and the template system, thereby realizing automatic compensation within the range of ±15 mm for the horizontal installation error and having the ability to adapt to the installation error.

[0019] like Figure 1 As shown, in step S1, at least one pair of adjustment mechanisms are symmetrically arranged along the axis on each side mold assembly 12. In this embodiment, two pairs of adjustment mechanisms are symmetrically arranged on the upper and lower sides of each side mold assembly 12 along the axis, so that the support frame 11 is subjected to more balanced force.

[0020] In step S2, the detection device includes a laser rangefinder and an inclination sensor. The laser rangefinder is used to measure the offset value between the axis of the support frame 11 and the symmetry center of the cast cylindrical structure 1. The inclination sensor is used to monitor the inclination angle of the support frame 11. After the cylindrical formwork system is installed, the laser rangefinder and the inclination sensor are used to detect the horizontal installation error of the support frame 11, and the control unit calculates whether the error direction and value are within the allowable range of ±2mm.

[0021] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of the claims.
