Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated sidewall jacking device. Background Technology

[0002] In prefabricated building construction, the precise installation of prefabricated components such as side walls, beams, and slabs directly affects the stability of the overall structure and construction efficiency. However, due to the large size and weight of the components, and the complex on-site construction environment, traditional assembly methods often rely on manual adjustment and hoisting equipment, resulting in low installation accuracy, low efficiency, and even potential impacts on construction quality due to improper adjustments. Taking side wall assembly as an example, the installation process requires ensuring the verticality, horizontal position, and docking accuracy of the components; otherwise, subsequent components may not be able to dock smoothly, potentially affecting the overall structural safety of the building. Therefore, how to improve the automation level of side wall assembly, reduce manual intervention, and improve installation accuracy has become a key technical issue in prefabricated building construction.

[0003] The existing precast component assembly mainly includes the following schemes: (1) Manual hoisting + manual adjustment: The side wall components are hoisted to the installation position by gantry crane or tower crane. The construction personnel manually adjust the posture of the components (such as using crowbars, jacks and other tools) to align them with the installation position. However, this method relies on manual experience, the adjustment accuracy is low, the efficiency is low, and there are safety hazards when working at height. (2) Hydraulic jacking assembly system: Hydraulic cylinders are installed in the gantry (such as the first gantry) of the assembly trolley. The construction personnel need to manually adjust the direction of the cylinders to make them perpendicular to the side wall, and then adjust the position of the side wall by hydraulic jacking. However, the cylinder angle needs to be manually adjusted before each installation, which is cumbersome and affects the construction efficiency. In addition, manual adjustment is prone to introducing errors, resulting in unstable side wall installation accuracy. (3) Mechanical arm assisted assembly: Some advanced construction equipment uses mechanical arms to hold components and automatically adjust them in combination with vision or laser positioning systems. However, this equipment is expensive, has poor adaptability to construction sites, is difficult to operate stably in complex environments, and has limited load capacity, making it unsuitable for large-sized, heavy sidewall components.

[0004] The purpose of this utility model is to provide a prefabricated sidewall jacking device to solve the technical problems of high cost and easy error in the installation of prefabricated sidewalls in the prior art. The specific technical solution is as follows:

[0005] This utility model provides a prefabricated sidewall jacking device, including a first gantry, a second gantry, and a jacking device. The first gantry is for attaching to the sidewall to be installed, the second gantry is used for positioning, the axial direction of the jacking device is horizontal, the jacking device is connected between the second gantry and the first gantry, and the jacking device is perpendicular to the second gantry and the first gantry.

[0006] A further improvement of the prefabricated sidewall jacking device of this utility model is that the first gantry includes a first lower crossbeam, the second gantry includes a second lower crossbeam, the first lower crossbeam and the second lower crossbeam are used to be attached to the installation floor slab, and the jacking device is connected between the first lower crossbeam and the second lower crossbeam.

[0007] A further improvement of this utility model's prefabricated sidewall jacking device is that the jacking device is a hydraulic cylinder, and a base for connecting the cylinder body is fixed on the second lower crossbeam.

[0008] A further improvement of this utility model of prefabricated sidewall jacking device is that the number of jacking devices is at least two, and the at least two jacking devices are arranged at intervals along the length direction of the first crossbeam.

[0009] A further improvement of the prefabricated sidewall jacking device of this utility model is that the first gantry includes a first rectangular frame, a first supporting horizontal beam and a supporting vertical beam. The first supporting horizontal beam is fixedly supported inside the first rectangular frame, and the supporting vertical beam is fixed between the first supporting horizontal beam and the first rectangular frame. The first rectangular frame is provided with the first lower horizontal beam.

[0010] A further improvement of the prefabricated sidewall jacking device of this utility model is that the second gantry includes a second rectangular frame, a second supporting beam and a diagonal brace. The second supporting beam is fixedly supported inside the second rectangular frame, and the diagonal brace is fixed between the second supporting beam and the second rectangular frame. The second rectangular frame is provided with the second lower beam.

[0011] The application of the technical solution of this utility model has the following beneficial effects:

[0012] This utility model relates to a prefabricated sidewall jacking device. First, a second gantry is used for positioning. The sidewall to be installed is then hoisted and attached to the side of the first gantry facing away from the second gantry. A jacking device, perpendicular to both the first and second gantry, pushes the first gantry horizontally, ensuring the thrust axis is naturally perpendicular to the mounting surface of the sidewall component. The jacking direction of the jacking device is completely aligned with the normal direction of the sidewall surface, allowing for direct forward jacking without manual angle adjustment. This achieves precise alignment and significantly improves the accuracy and efficiency of sidewall assembly, overcoming errors introduced by manual hoisting and hydraulic jacking systems. The reaction force during the jacking process is directly transmitted to the main structure of the gantry, effectively enhancing the overall stability of the system and preventing structural deformation or damage due to localized stress concentration, thus improving safety and equipment lifespan. Furthermore, this utility model features a simple structure, low cost, and high reliability, adapting to complex construction site environments and possessing stronger load-bearing capacity. It is suitable for assembling large-size, heavy-duty prefabricated sidewall components, reducing construction risks while increasing automation. This solves the technical problems of high equipment cost and easy error in the installation of prefabricated sidewalls in existing technologies.

[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] See Figures 1-4 As shown, a prefabricated sidewall jacking device includes a first gantry, a second gantry, and a jacking device 5. The first gantry is used for attaching the sidewall 11 to be installed, the second gantry is used for positioning, the axial direction of the jacking device 5 is horizontal, the jacking device 5 is connected between the second gantry and the first gantry, and the jacking device 5 is perpendicular to the second gantry and the first gantry.

[0022] Before installing the sidewall, the levelness of the floor slab to which the sidewall is installed should be ensured. This ensures that the first gantry, second gantry, and jacking device 5 are all naturally horizontal when placed on the floor slab. When the first gantry is against the sidewall surface, the thrust axis of the jacking device 5 is naturally perpendicular to the mounting surface of the sidewall component to be installed. The jacking direction of the jacking device 5 is completely consistent with the normal direction of the sidewall component surface, allowing for direct forward jacking. Due to the natural perpendicular relationship between the installation position of the jacking device 5 and the mounting surface of the component, the tedious operation of manually adjusting the cylinder angle is eliminated, improving the accuracy and efficiency of jacking positioning.

[0023] Preferably, the first gantry includes a first lower crossbeam 4, and the second gantry includes a second lower crossbeam 9. The first lower crossbeam 4 and the second lower crossbeam 9 are used to be attached to the installation floor slab, and the jacking device 5 is connected between the first lower crossbeam 4 and the second lower crossbeam 9.

[0024] Preferably, the pusher 5 is a hydraulic cylinder, and a base 10 for connecting the cylinder body is fixed on the second lower crossbeam 9. The base 10 can be fixed to the second lower crossbeam 9 by bolt connection, thereby firmly installing the base 10 on the second lower crossbeam 9. This layout design ensures that the reaction force generated by the hydraulic cylinder during the pushing process can be directly transmitted to the main structure of the gantry, effectively preventing problems such as stress deformation or unstable installation, and improving the overall stability and safety of the system. In this embodiment, the hydraulic cylinder is a single-cylinder direct-push structure, which is convenient for maintenance and replacement.

[0025] Preferably, the number of the pushers 5 is at least two, and the at least two pushers 5 are arranged at intervals along the length direction of the first crossbeam.

[0026] Preferably, the first gantry includes a first rectangular frame 1, a first supporting crossbeam 2 and a supporting vertical beam 3. The first supporting crossbeam 2 is fixedly supported inside the first rectangular frame 1, and the supporting vertical beam 3 is fixed between the first supporting crossbeam 2 and the first rectangular frame 1. The first rectangular frame 1 is provided with the first lower crossbeam 4.

[0027] Preferably, the second gantry includes a second rectangular frame 6, a second supporting beam 7, and a diagonal brace 8. The second supporting beam 7 is fixedly supported within the second rectangular frame 6, and the diagonal brace 8 is fixed between the second supporting beam 7 and the second rectangular frame 6. The second rectangular frame 6 is provided with a second lower beam 9. Further, the first and second gantry are movable structures, with retractable wheel sets equipped on the sides of the first rectangular frame 1 and the second rectangular frame 6 to facilitate the movement and positioning of the entire equipment. The retractable wheel set includes a fixed block, a telescopic cylinder, and wheels. The fixed block is fixed to the side of the vertical member of the first rectangular frame 1 or the second rectangular frame 6, and the telescopic cylinder is connected between the fixed block and the wheels. The extension and retraction of the telescopic cylinder allows the wheels to contact or leave the floor slab. When pushing is required, the telescopic cylinder retracts, allowing the first and second masts to be directly supported on the floor. When moving is required, the telescopic cylinder extends, allowing the traveling wheels to support the first and second masts, lifting them off the ground, thus enabling the overall movement of the equipment.

[0028] During use, the second gantry is positioned on the floor according to the installation position of the side wall 11 to be installed. After the side wall 11 to be installed is hoisted to an approximate position by the gantry crane, it is placed on the floor and attached to the side of the first gantry facing away from the second gantry. Alternatively, the first gantry can be directly pushed onto the side wall 11 to be installed by the pusher 5. The pusher 5 continues to push the first gantry and thus push the side wall 11 to be installed until it is in the precise installation position. By controlling the pusher 5, the positive force and alignment adjustment of the side wall 11 to be installed can be automatically completed, ensuring that the posture and position of the side wall 11 to be installed meet the design requirements during the assembly process. The assembly accuracy is high and the manual intervention is minimal.

[0029] This utility model deeply integrates the hydraulic cylinder with the first and second gantry frames, using the gantry structure as the installation support for the hydraulic cylinder. At the same time, it rationally arranges the hydraulic pipelines and control units to ensure that the overall equipment is compact, has high space utilization, adapts to the layout requirements of the construction site, and does not affect the hoisting and assembly operations of other components.

[0030] This utility model relates to a prefabricated sidewall jacking device. First, a second gantry is used for positioning. The sidewall 11 to be installed is then hoisted and attached to the side of the first gantry facing away from the second gantry. Then, a jacking device 5, perpendicular to both the first and second gantry, pushes the first gantry horizontally, ensuring the thrust axis is naturally perpendicular to the mounting surface of the sidewall component. The jacking direction of the jacking device 5 is completely consistent with the normal direction of the surface of the sidewall 11, allowing for direct forward jacking without manual angle adjustment. This achieves precise alignment and jacking, significantly improving the accuracy and efficiency of sidewall assembly. It overcomes the errors introduced by manual hoisting and hydraulic jacking systems due to human adjustment, and solves the technical problems of high cost and error-prone equipment in existing prefabricated sidewall installation technologies. The reaction force generated during the jacking process can be directly transferred to the main structure of the gantry, effectively enhancing the overall stability of the system, avoiding structural deformation or damage caused by local stress concentration, and improving safety and equipment lifespan. Moreover, the present invention has a simple structure, low cost, and high reliability, can adapt to complex construction site environments, and has a stronger load-bearing capacity. It is suitable for the assembly of large-size and heavy prefabricated sidewall components, reducing construction risks while improving the level of automation.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
