Description

Technical Field

[0001] This invention relates to the field of prefabricated building components, specifically a device for real-time monitoring and correction of axial deviation during the installation of prefabricated building components. Background Technology

[0002] In prefabricated buildings, the installation accuracy of precast wall panels, columns, beams, and other components directly affects the integrity and safety of the building structure. Controlling the axial position during component installation is crucial for ensuring the structural verticality and planar accuracy. However, due to factors such as swaying during hoisting, component deformation due to its own weight, and deviations in the position of foundation embedded parts, axial offsets often occur after components are in place. If these offsets are not detected and corrected in time, the accumulated deviations will prevent the proper installation of subsequent components and may even affect the structural load-bearing performance.

[0003] Currently, axis detection for precast component installation mainly relies on manual measurement using total stations, theodolites, or laser collimators. Operators take multiple measurements and make repeated adjustments during component hoisting, a time-consuming and labor-intensive process significantly affected by the surveyor's experience and environmental conditions, resulting in poor real-time accuracy. For components that have already shifted, correction operations often involve manual adjustments using tools such as crowbars and jacks, which is not only labor-intensive but also makes it difficult to guarantee fine-tuning precision, easily causing damage to component edges or bending of connecting reinforcing bars during the correction process. Furthermore, existing correction devices are mostly single-function, lacking automated equipment that integrates real-time axis monitoring, offset judgment, and precise correction.

[0004] Therefore, there is an urgent need for a device that can monitor the axial deviation of prefabricated components in real time and automatically and accurately correct it, so as to improve the efficiency, accuracy and quality of prefabricated building construction. Summary of the Invention

[0038] The workflow of this invention is as follows:

[0039] The workflow of the real-time monitoring and correction device for the axial offset of precast building components can be divided into five stages: device installation and leveling, component positioning and axial monitoring, deployment of correction components, clamping and correction, and temporary fixing and removal. The actions of the components involved in each stage are detailed below.

[0040] I. Installation and Leveling Stage

[0041] The support ring 1 is fitted around the precast component to be installed through its notch. The first handle 303 of each support positioning mechanism 3 is rotated to adjust the extension length of the support sleeve 302, changing the support height of the support ring 1. The second handle 305 is rotated to adjust the depth to which the positioning rod 304 is inserted into the ground or floor slab, firmly supporting the support ring 1 on the construction platform. Based on real-time feedback from the electronic level sensor 4, each support positioning mechanism 3 is fine-tuned until the support ring 1 reaches a horizontal state, establishing a precise axis detection benchmark.

[0042] II. Component Placement and Axis Monitoring Stage

[0043] The prefabricated component is hoisted to the central area of ​​the support ring 1 and initially positioned. The laser positioning sensors 5 arranged circumferentially on the inner side of the support ring 1 are activated to measure the radial distance between the outer surface of the component and the center of the support ring 1 in real time, calculate the offset direction and amount of the component axis from the design position, and transmit the monitoring data to the control system in real time.

[0044] III. Deployment Phase of Correction Components

[0045] According to the direction of axis offset, the first motor 702 of the rotating gear mechanism 7 is started, driving the gear 703 to roll along the arc rack 8, which in turn drives the moving arc ring mechanism 6 to move around along the sliding slot 2, moving each positioning and correction component installed on the moving arc plate 601 to the position where the correction force needs to be applied.

[0046] The second hydraulic telescopic rod 1102 of the deflection adjustment mechanism 11 is activated, pushing the first hydraulic telescopic rod 1002 to swing around the first deflection seat 1001, adjusting the overall pitch attitude of the positioning arc plate mechanism 10. The first hydraulic telescopic rod 1002 is activated to adjust the radial position of the positioning arc plate 1005, bringing it close to the outer surface of the component. The second motor 1006 is activated, driving the positioning arc plate 1005 to deflect around the second deflection seat 1004 at a small angle via the deflection shaft 1003, so that its inner arc surface is parallel and in contact with the outer surface of the component.

[0047] IV. Tightening and Correction Phase

[0048] The third hydraulic telescopic rod 1201 of the positioning mechanism 12 is activated, driving the displacement plate 1202 and the slide rod 1203 to move towards the component. The inner arc surface of the clamping plate 1204 is pressed against the outer surface of the component, clamping the component onto the positioning arc plate 1005.

[0049] Based on the axis offset data, each positioning and correction component operates in concert. The first hydraulic telescopic rod 1002 extends and retracts, applying radial thrust or tension to the component; the second motor 1006 drives the positioning arc plate 1005 to deflect, causing the component to rotate slightly. Multiple positioning and correction components apply precise correction forces synchronously from different directions, gradually returning the component's axis to its designed position. If multiple positioning arc plates 1005 need to work together, adjacent positioning arc plates 1005 can be connected and fixed by connecting rods passing through the connecting through holes 1007, achieving overall synchronous correction.

[0050] V. Temporary Fixing and Exit Phase

[0051] After the component axis returns to its designed position, the third hydraulic telescopic rod 1201 of each positioning mechanism 12 remains extended, and the clamping plate 1204 continues to clamp the component, temporarily fixing it. Construction personnel then complete the permanent connection of the component. After the permanent connection is completed, the third hydraulic telescopic rod 1201 retracts, and the clamping plate 1204 releases the component. Each hydraulic telescopic rod and motor resets, the positioning and correction assembly moves away with the moving arc ring mechanism 6, and the support ring 1 is removed from the component, completing the installation and correction process for one component.

[0052] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
