Description

Technical Field

[0001] This invention relates to the field of prefabricated building construction technology, specifically to a double-guide rail sliding positioning tool and construction method for prefabricated wall panels. Background Technology

[0002] With the industrialization and large-scale development of prefabricated building industry in my country, prefabricated wall panels, with their advantages of industrial prefabrication, on-site assembly, energy conservation and environmental protection, and short construction cycle, have become core components of building envelope and internal partition structures, and are widely used in various engineering scenarios such as residential, commercial, and public buildings. As the requirements for standardization and precision in building construction continue to increase, the industry has set higher standards for the installation accuracy, construction efficiency, operational safety, and tool versatility of prefabricated wall panels.

[0003] Currently, the on-site installation of prefabricated wall panels in China still relies mainly on traditional methods such as manual hoisting and temporary support positioning. The supporting construction tools are simple in structure and have limited functions. A standardized and integrated precision positioning construction system has not yet been formed, and there are many technical defects that urgently need to be addressed.

[0004] 1. Poor installation accuracy and difficulty in controlling construction quality: Traditional installation methods rely entirely on manual visual inspection and fine-tuning of positioning. During the hoisting and placement of wall panels, problems such as horizontal deviation, vertical deviation, and forward and backward tilting are prone to occur. At the same time, when splicing multiple wall panels, quality defects such as uneven joint width and misalignment of panel height are very likely to occur. This not only affects the appearance of the building facade and interior decoration, but in severe cases, it can lead to uneven stress on the wall panels, reduce the overall structural stability, and leave safety hazards.

[0005] 2. High labor costs and low construction efficiency: The installation of a single prefabricated wall panel requires 3-5 construction workers to work together to complete the entire process of hoisting, supporting, aligning, fine-tuning and fixing. Moreover, manual correction requires repeated adjustments, making the installation of a single wall panel time-consuming. When multiple wall panels are installed continuously, there is no standardized assembly line system, the process is complicated, the overall construction efficiency is extremely low, and it is difficult to adapt to the needs of large-scale prefabricated construction.

[0006] 3. The operation is high-risk and has prominent safety hazards. The wall panel hoisting and positioning process mainly relies on manual support and fixation. The wall panel has a large self-weight, and the stability of manual force is poor, which makes it very easy for the wall panel to tilt, shift, or collide during hoisting, which may cause safety accidents such as falling objects or falling from heights. At the same time, the close-range manual alignment and correction and the narrow working space further exacerbate the construction safety risks.

[0007] 4. Poor tool versatility and serious resource waste: Existing temporary supports and simple clamping tools are mostly fixed structures with fixed dimensions and clamping ranges, only suitable for single-specification wall panels. Different tools need to be customized for wall panels of different heights, widths, and thicknesses, resulting in low tool reuse rates. Furthermore, temporary supports have poor stability and insufficient rigidity, are prone to deformation, and have short service lives, leading to waste of construction materials and increased construction costs. Therefore, they do not meet the current needs. To address this, we propose a prefabricated wall panel double-guide rail sliding positioning tool and construction method. Summary of the Invention

[0008] The purpose of this invention is to provide a prefabricated wall panel double-guide rail sliding positioning tool and construction method. Through the parallel guidance of the double guide rails, combined with upper and lower trolleys and limiting supports, the sliding groove is precisely limited to prevent wall panel displacement and tilting. The clamping groove at the top of the equipment quickly clamps the wall panel, allowing a single person to complete the sliding positioning. Continuous construction is possible, saving manpower and resources. The mechanical tooling replaces the high-risk manual operation, avoiding the risk of tipping and falling. The bolts are adjustable to adapt to various wall panels, allowing for cross-scenario reuse and saving consumables and construction costs, thus solving the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated wall panel double-guide rail sliding positioning tool, comprising a mounting base and a guide rail base. The mounting base has a first fixing bolt hole and is fixed to the prefabricated wall panel working surface by a matching first mounting bolt. A base pad is mounted on the bottom of the mounting base. The guide rail base is fixed to the prefabricated wall panel working surface by a second mounting bolt and is arranged perpendicularly to the mounting base. The guide rail base plate has a second fixing bolt hole. A guide rail groove is opened on the inner side of the guide rail base. A top trolley is slidably mounted inside the guide rail groove. The top trolley and the bottom trolley are sliding components arranged vertically and correspondingly. A first pulley is mounted on the outer side of the top trolley, and a second pulley is mounted on the outer side of the bottom trolley. A top clamping groove is hinged to the end of the top trolley by a top hinge.

[0010] Preferably, the top surface of the mounting base is integrally formed with a positioning support, a base inclined rail, a base groove, and a base sliding groove, and the bottom of the guide rail base is integrally formed with a guide rail inclined rail. The base inclined rail and the guide rail inclined rail are precisely connected to form an integrated sliding slope, enabling the prefabricated wall panel to slide smoothly into place.

[0011] Preferably, the mounting base and the guide rail base are made of steel, the first mounting bolt and the first mounting bolt are high-strength bolts, and the bottom of the base plate is provided with anti-slip texture.

[0012] Preferably, both the base inclined rail and the guide inclined rail are provided with smooth inclined surfaces, and the inner walls of the base groove and the guide groove are smooth, which can reduce the wear of the grooves and the sliding resistance between them.

[0013] Preferably, both the first pulley and the first roller are silent pulleys, respectively matched and embedded in the guide rail groove and the base groove. Both the first pulley and the first roller are provided with anti-detachment grooves. The inner side of the top trolley is equipped with a first double-ended bolt, and the inner side of the bottom trolley is equipped with a second double-ended bolt. The top trolley and the bottom trolley are finely adjusted by the first double-ended bolt and the second double-ended bolt, respectively. The first double-ended bolt and the second double-ended bolt are tightened or loosened synchronously by rotation.

[0014] Preferably, the positioning support is provided with a limiting block, the base groove and the base pad are on the same horizontal line, and polyurethane buffer limiting blocks are provided at both ends of the guide rail groove and the base groove.

[0015] Preferably, the top clamping groove includes a movable clamping plate, and an anti-slip silicone protective pad is attached to the inner side of the movable clamping plate.

[0016] Preferably, the top trolley and the bottom trolley are equipped with a synchronous linkage mechanism, the guide rail base is a modular splicing structure, and a horizontal indicator is provided on the mounting base.

[0017] A construction method applied to a prefabricated wall panel double-guide rail sliding positioning tool includes the following steps:

[0018] S1: Clean up debris and dust from the base layer of the construction site, and accurately mark the wall panel installation positioning line and the installation elevation line of the installation base according to the construction drawings to determine the installation position of the installation base and the guide rail base;

[0019] S2: After the mounting base and guide rail base are assembled, fix the mounting base and guide rail base to the wall surface with the first mounting bolt and the first mounting bolt to ensure that the tool is in close contact with the base layer and there is no looseness.

[0020] S3: Install the top trolley and bottom trolley into the guide rail groove and base groove respectively. According to the wall panel specifications, fine-tune the first and second double-headed bolts of the top trolley and bottom trolley, and install the top clamping groove of appropriate specifications.

[0021] S4: According to the height and thickness specifications of the prefabricated wall panel, rotate the first double-headed bolt and the second double-headed bolt to adjust the extension length of the top trolley and the bottom trolley to match the installation dimensions of the prefabricated wall panel. Debug the synchronous linkage mechanism to ensure the synchronous sliding of the top trolley and the bottom trolley. Open the top hinge to open the movable clamping plate and insert the top of the prefabricated wall panel into the top clamping groove. Fine-tune the verticality and horizontal position of the wall panel to make the bottom of the wall panel fit tightly against the base plate.

[0022] S5: Open the movable clamping plate through the top hinge, insert the top of the prefabricated wall panel into the top clamping groove, and let the bottom of the prefabricated wall panel fit against the base pad. Fine-tune the verticality and horizontal position of the prefabricated wall panel, close the movable clamping plate and lock it with one click. Use the inner anti-slip silicone pad to achieve a stable and damage-free clamping. After the position of the prefabricated wall panel is adjusted, close the movable clamping plate to complete the clamping and fixing, ensuring that the wall panel is vertical and that the tilt angle and position meet the design requirements.

[0023] S6: Horizontally push the prefabricated wall panel, open the movable clamp, and the top trolley and bottom trolley slide smoothly along the double guide rails of the guide rail groove and the base groove, respectively, driving the prefabricated wall panel to the designed installation position. After sliding into place, the prefabricated wall panel slides smoothly down the sliding slope formed by the base inclined rail and the guide rail inclined rail, and is automatically locked into the limit block of the positioning support.

[0024] S7: Check the verticality, joint width, and horizontal position of the prefabricated wall panels. After confirming that the installation accuracy meets the specifications, complete the base fixing of the prefabricated wall panels, open the top clamping clips, loosen the movable clamping structure, and remove the construction tools.

[0025] S8: Clean the tool surface of debris and dust, check the integrity of the first pulley, second pulley, first double-ended bolt, second double-ended bolt, and top clamping groove structure, and transfer it to the next work station for reuse. When constructing prefabricated wall panels of different specifications, only the spacing of the first double-ended bolt and the second double-ended bolt needs to be slightly adjusted to complete the adaptation.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention employs a dual-rail parallel guiding system consisting of an installation base and a guide rail base. Combined with the constraint and guiding effects of the top and bottom trolleys and the positioning support limiting structure, the prefabricated wall panel slides along a fixed track throughout its installation. Through the precise guidance and limiting of the base groove and guide rail groove, horizontal offset and vertical tilt of the wall panel are effectively constrained. The installation position, verticality, and joint width of the wall panel are precisely controlled, resulting in a flat surface without unevenness and uniform, regular joints. This significantly improves the aesthetic quality of the prefabricated wall panel installation. Simultaneously, it ensures uniform stress on the wall panel installation, enhancing the stability and reliability of the overall assembly structure. The smooth inner wall of the groove reduces sliding friction resistance, ensuring a smooth and stable sliding process. This avoids wall panel misalignment and damage caused by manual alignment, bumps, or forced corrections, effectively protecting the integrity of the finished wall panel.

[0028] 2. This invention enables the rapid fixing and clamping of prefabricated wall panels through the top clamping groove. The wall panels can be pushed into place smoothly by the top and bottom trolleys sliding along the track, eliminating the need for repeated manual fine-tuning and correction. The installation of a single prefabricated wall panel can be completed independently by one construction worker, significantly reducing on-site labor input. At the same time, the overall structure of the equipment is neat, easy to assemble and disassemble, and reliable in positioning. It can realize the continuous sequential placement of multiple wall panels and the assembly line construction operation, effectively shortening the construction period of the prefabricated wall panel sub-project and reducing on-site labor construction costs.

[0029] 3. This invention adopts a mechanical tooling-supported sliding positioning mode, replacing the traditional high-risk construction method of manual close-range hand-holding and alignment of wall panels. The prefabricated wall panels are held and fixed by the top clamping groove throughout the process and are supported and constrained by the upper and lower double-track sliding structure. The wall panels are under stable force and have a fixed movement trajectory, effectively eliminating the risks of tipping, shifting, shaking, and falling during the wall panel hoisting process. At the same time, the first and second pulleys are equipped with anti-detachment slot structures to ensure that the trolley does not derail or come off during the sliding process, and the equipment operates stably and reliably. Combined with the high-strength earthquake-resistant locking structure of the first and second mounting bolts, the impact of vibration during construction can be effectively offset, avoiding problems such as tooling loosening, instability, and falling off. This greatly improves the safety redundancy of high-altitude and indoor installation of prefabricated wall panels and achieves safe and standardized construction.

[0030] 4. This invention utilizes the telescopic adjustment structure of the first and second double-headed bolts configured on the top and bottom trolleys. This allows for flexible adjustment of the clamping and fitting spacing according to the different heights and thicknesses of the prefabricated wall panels. It is compatible with most prefabricated concrete wall panels, lightweight partition walls, decorative wall panels, and other component types available on the market. The main body of the tooling is made of high-strength steel, offering high overall rigidity, good bending resistance, and wear and damage resistance. It can withstand the long-term repeated construction loads of large self-weight wall panels without easily deforming or being damaged. The entire tool set is easy to assemble and disassemble, simple to maintain, and can be reused across different work conditions and buildings. It eliminates the need for repeatedly customizing temporary tooling for different wall panels, significantly reducing waste of construction materials and investment in temporary facilities, and substantially lowering the installation cost of prefabricated wall panels.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To address the problems of poor installation accuracy, difficulty in controlling construction quality, high labor costs, low construction efficiency, high operational risks, significant safety hazards, and poor tool versatility leading to serious resource waste associated with existing technologies, please refer to [link / reference needed]. Figures 1-4 This embodiment provides the following technical solution:

[0038] A prefabricated wall panel double-rail sliding positioning tool includes a mounting base 1, which is an integral load-bearing foundation. The mounting base 1 has a first fixing bolt hole 101, which is fixed to the working surface of the prefabricated wall panel 7 by a matching first mounting bolt 102. The bottom of the mounting base 1 has a detachable mounting base pad 5 to ensure overall horizontal stability. The top surface of the mounting base 1 is integrally formed with a positioning support 103, a base inclined rail 104, a base groove 105, and a base sliding groove 106. The base sliding groove 106 is a sliding guide channel for the bottom trolley 4. The base inclined rail 104 and the base groove 105 cooperate to realize the rapid positioning and sliding of the bottom of the prefabricated wall panel 7.

[0039] The guide rail base 2 is fixed to the working surface of the prefabricated wall panel 7 by the second mounting bolt 202 and is arranged perpendicularly to the mounting base 1. The guide rail base 2 has a second fixing bolt hole 201 on its surface. The guide rail base 2 has a guide rail groove 203 on its inner side. The top trolley 3 is slidably assembled inside the guide rail groove 203. The bottom of the guide rail base 2 has an integrally formed guide rail inclined rail 204. The base inclined rail 104 and the guide rail inclined rail 204 are precisely connected to form an integral sliding slope, so as to realize the smooth sliding of the prefabricated wall panel 7 into place.

[0040] The top trolley 3 and the bottom trolley 4 are sliding components arranged vertically and vertically. The outer side of the top trolley 3 is equipped with a first pulley 301, and the outer side of the bottom trolley 4 is equipped with a second pulley 401. Both the first pulley 301 and the second pulley 401 are silent and anti-detachment structures, respectively matched and embedded in the guide rail groove 203 and the base groove 106. The inner side of the top trolley 3 is equipped with a first double-ended bolt 302, and the inner side of the bottom trolley 4 is equipped with a second double-ended bolt 402. By rotating the first double-ended bolt 302 and the second double-ended bolt 402, the telescopic length can be adjusted synchronously to adapt to the prefabricated wall panels 7 of different heights and thicknesses.

[0041] The top clamping groove 6 is hinged to the end of the top trolley 3 via the top hinge 601. It is an openable clamping structure, including a movable clamping plate 602. The inner side of the movable clamping plate 602 is attached with an anti-slip silicone protective pad 603, which can clamp the assembled wall panel 7 without damage.

[0042] The mounting base 1 and guide rail base 2 are made of steel profiles, which have high overall rigidity and good bending resistance, and can withstand heavy prefabricated wall panels. The first mounting bolt 102 and the first mounting bolt 202 are high-strength bolts, with matching washers and nuts, which can prevent the wall panels from loosening due to vibration during sliding.

[0043] Both the base inclined rail 104 and the guide rail inclined rail 204 are provided with smooth inclined surfaces to facilitate the sliding and docking of the plates. The inner walls of the base slide groove 106 and the guide rail slide groove 203 are smooth, which can reduce mutual slide groove wear and sliding resistance.

[0044] Both the first pulley 301 and the first pulley 401 are silent pulleys, which can effectively protect the inner wall of the slide. Both the first pulley 301 and the first pulley 401 are equipped with anti-detachment grooves to prevent the trolley from detaching during the sliding process.

[0045] The first double-ended bolt 302 and the second double-ended bolt 402 are tightened or loosened synchronously by rotation, improving applicability. This allows the first double-ended bolt 302 and the second double-ended bolt 402 to adapt to prefabricated wall panels of different heights, providing a wide adjustment range and strong versatility. The bottom of the base plate 5 has anti-slip textures, which increases friction with the prefabricated wall panel 7 and prevents the prefabricated wall panel 7 from falling off during sliding. The mounting base 1 is equipped with a high-precision level indicator, which, together with the height fine-tuning structure of the base plate 5, enables rapid and accurate leveling on site, ensuring that the levelness and parallelism of the double guide rails meet the standards.

[0046] The positioning support 103 is equipped with a limit block to lock the prefabricated wall panel 7 after it is in place, preventing the wall panel from over-positioning. The base groove 105 and the base pad 5 are on the same horizontal line, which enables the bottom of the prefabricated wall panel 7 to be quickly positioned and slid.

[0047] Polyurethane buffer limit blocks 8 are provided at both ends of the guide rail slide 203 and the base slide 106 to buffer the sliding impact of the first pulley 301 and the second pulley 401, and prevent the top trolley 3 and the bottom trolley 4 from derailing and the track and trolley structure from being damaged by collision.

[0048] The top trolley 3 and the bottom trolley 4 are equipped with a synchronous linkage mechanism to ensure that the upward and downward sliding speeds are consistent. The guide rail base 2 is a modular splicing structure, which can be freely spliced ​​to lengthen or cut to shorten according to the installation length of the prefabricated wall panel 7, adapting to the installation of wall panels with different spans. The installation base 1 is equipped with a level indicator to facilitate quick leveling on site during installation.

[0049] A construction method applied to a prefabricated wall panel double-guide rail sliding positioning tool includes the following steps:

[0050] S1: Clean up debris and dust from the construction site. Accurately mark the wall panel installation positioning line and the installation elevation line of the installation base 1 according to the construction drawings. Determine the installation positions of the installation base 1 and the guide rail base 2. Fix the installation base 1 and the guide rail base 2 to the wall surface using the first installation bolt 102 and the first installation bolt 202 to ensure that the tools are in close contact with the base and are not loose.

[0051] S2: Assemble the guide rail base 2 of the appropriate length according to the wall panel specifications. Fix the mounting base 1 to the working surface with the first mounting bolt 102 and the first mounting bolt 202. Complete the precise leveling by cooperating with the base pad 5 and the level indicator to ensure that the horizontal error of the mounting base 5 is ≤2mm. Fix the guide rail base 2 so that the base inclined rail and the guide rail inclined rail are precisely aligned. Make fine adjustments to the first double-headed bolt 302 and the second double-headed bolt 402 of the top trolley 3 and the bottom trolley 4 to match the wall panel installation size. Debug the synchronous linkage mechanism to ensure the synchronous sliding of the upper and lower trolleys. At the same time, install the top clamping groove 6 of appropriate specifications.

[0052] S3: Install the top trolley 3 and the bottom trolley 4 into the guide rail groove 203 and the base groove 106 respectively. According to the wall panel specifications, make minor adjustments to the first double-headed bolt 302 and the second double-headed bolt 402 of the top trolley 3 and the bottom trolley 4, and install the top clamping groove 6 of appropriate specifications.

[0053] S4: According to the height and thickness specifications of the prefabricated wall panel 7, rotate the first double-headed bolt 302 and the second double-headed bolt 402 to adjust the extension length of the top trolley 3 and the bottom trolley 4 to match the installation dimensions of the prefabricated wall panel 7. Debug the synchronous linkage mechanism to ensure the synchronous sliding of the top trolley 3 and the bottom trolley 4. Open the top hinge 601 to open the movable clamping plate 602, and insert the top of the prefabricated wall panel 7 into the top clamping groove 6. Fine-tune the verticality and horizontal position of the wall panel to make the bottom of the wall panel fit tightly against the base pad 5.

[0054] S5: Open the movable clamping plate 602 through the top hinge 601, insert the top of the prefabricated wall panel 7 into the top clamping groove 6, and let the bottom of the prefabricated wall panel 7 fit against the base pad 5. Fine-tune the verticality and horizontal position of the prefabricated wall panel 7, close the movable clamping plate 602 and lock it with one click. Use the inner anti-slip silicone pad to achieve a stable and damage-free clamping. After the position of the prefabricated wall panel 7 is adjusted, close the movable clamping plate 602 to complete the clamping and fixing, ensuring that the wall panel is vertical and that the tilt angle and position meet the design requirements.

[0055] S6: Push the prefabricated wall panel 7 horizontally, open the movable clamp 602, and the top trolley 3 and bottom trolley 4 slide smoothly along the double guide rails 203 and 106 respectively, driving the prefabricated wall panel 7 to the designed installation position. After sliding into place, the prefabricated wall panel 7 slides smoothly down the sliding slope formed by the base inclined rail 104 and the guide rail inclined rail 204, and automatically locks into the limiting block of the positioning support 103.

[0056] S7: Verify the verticality, joint width, and horizontal position of the prefabricated wall panel 7. After confirming that the installation accuracy meets the specifications, complete the base fixing of the prefabricated wall panel 7, open the top clamping groove 6 buckle, loosen the movable clamping plate 602 clamping structure, and remove the construction tools.

[0057] S8: Clean the surface of the tool to remove debris and dust, check the integrity of the structure of the first pulley 301, the second pulley 401, the first double-ended bolt 302, the second double-ended bolt 402 and the top clamping groove 6, and transfer it to the next work station for reuse. When constructing prefabricated wall panels 7 of different specifications, only the spacing between the first double-ended bolt 302 and the second double-ended bolt 402 needs to be adjusted to complete the adaptation.

[0058] When used for continuous installation of multiple wall panels, the tool parameters can be adjusted in advance to complete the fixing of multiple wall panels at one time, and they can be placed in sequence, reducing labor input while ensuring installation quality. When it is necessary to adapt to prefabricated wall panels of different specifications, the tool can be adapted by adjusting the clamping distance of the first double-headed bolt 302 and the second double-headed bolt 402 and replacing the appropriate protective pad, without having to replace the entire main structure of the tool.

A construction method applied to the prefabricated wall panel double-guide rail sliding positioning tool as described in claim 8, characterized in that, Includes the following steps: S1: Clean up debris and dust on the construction site, and accurately mark the wall panel installation positioning line and the installation elevation line of the installation base (1) according to the construction drawings to determine the installation position of the installation base (1) and the guide rail base (2); S2: After the mounting base (1) and guide rail base (2) are assembled, the mounting base (1) and guide rail base (2) are fixed to the wall surface by the first mounting bolt (102) and the first mounting bolt (202) so that the tool is in close contact with the base layer and there is no looseness; S3: Insert the top trolley (3) and bottom trolley (4) into the guide rail groove (203) and base groove (106) respectively. According to the wall panel specifications, make fine adjustments to the first double-headed bolt (302) and the second double-headed bolt (402) of the top trolley (3) and bottom trolley (4), and install the top clamping groove (6) of appropriate specifications. S4: According to the height and thickness specifications of the prefabricated wall panel (7), rotate the first double-headed bolt (302) and the second double-headed bolt (402) to adjust the extension length of the top carriage (3) and the bottom carriage (4) to match the installation dimensions of the prefabricated wall panel (7), debug the synchronous linkage mechanism to ensure the sliding synchronization of the top carriage (3) and the bottom carriage (4), open the top hinge (601) to open the movable clamping plate (602), insert the top of the prefabricated wall panel (7) into the top clamping groove (6), finely adjust the verticality and horizontal position of the wall panel to make the bottom of the wall panel fit tightly with the base pad (5); S5: Open the movable clamp (602) through the top hinge (601), insert the top of the prefabricated wall panel (7) into the top clamping groove (6), and attach the bottom of the prefabricated wall panel (7) to the base pad (5). Fine-tune the verticality and horizontal position of the prefabricated wall panel (7), close the movable clamp (602) and lock it with one key. Use the inner anti-slip silicone pad to achieve stable and damage-free clamping. After the position of the prefabricated wall panel (7) is adjusted, close the movable clamp (602) to complete the clamping and fixing, and ensure that the wall panel is vertical and the tilt angle and position meet the design requirements. S6: Push the prefabricated wall panel (7) horizontally, open the movable clamp (602), and the top trolley (3) and bottom trolley (4) slide smoothly along the double guide rails (203) and base trolley (106) respectively, driving the prefabricated wall panel (7) to the designed installation position. After sliding into place, the prefabricated wall panel (7) slides smoothly down the sliding slope formed by the base inclined rail (104) and the guide rail inclined rail (204), and automatically locks into the limiting block of the positioning support (103); S7: Check the verticality, joint width and horizontal position of the prefabricated wall panel (7). After confirming that the installation accuracy meets the specifications, fix the base layer of the prefabricated wall panel (7), open the top groove (6) buckle, loosen the movable clamp (602) clamping structure, and remove the construction tools. S8: Clean the surface of the tool to remove debris and dust, check the structural integrity of the first pulley (301), the second pulley (401), the first double-ended bolt (302), the second double-ended bolt (402), and the top groove (6), and transfer it to the next work station for reuse. When constructing prefabricated wall panels (7) of different specifications, only the spacing of the first double-ended bolt (302) and the second double-ended bolt (402) needs to be slightly adjusted to complete the adaptation.
