Description

Technical Field

[0001] This invention relates to the field of prefabricated building construction technology, and in particular to a high-precision splicing and installation method for ALC wall panels. Background Technology

[0002] In the field of prefabricated building construction, autoclaved aerated concrete (ALC) wall panels are widely used due to their excellent properties such as lightweight, thermal insulation, and fire resistance. The installation of ALC wall panels typically involves multiple processes, including panel transportation, positioning, adjustment, fixing, and joint treatment.

[0003] Currently, traditional ALC wall panel installation mainly relies on manual operation or semi-mechanized assistance. The handling, flipping, and positioning of the wall panels are mostly completed manually with the aid of simple hoisting equipment, which presents the following problems during the construction process:

[0004] (1) Low efficiency of manual handling: ALC wall panels are large in size and heavy in weight, and manual handling is labor-intensive and can easily cause damage to the corners of the wall panels, affecting construction quality and material utilization.

[0005] (2) Difficulty in alignment adjustment: When installing wall panels, it is necessary to accurately align the axis, control line and the joints of adjacent wall panels. In traditional construction, manual visual inspection and pry bar adjustment are relied upon, which makes it difficult to guarantee the alignment accuracy. This can easily lead to problems such as uneven joints and poor wall flatness, affecting the overall construction quality.

[0006] (3) Danger of flipping operation: During the process of flipping the wall panels from the horizontal stacking state to the vertical installation state, the stability of manual operation is poor, which poses a safety hazard and is easy to damage the wall panels.

[0007] (4) Discontinuous process connection: There is a lack of integrated coordination between the processes of transporting, inspecting, flipping, positioning and adjusting the wall panels. There are many manual operation links and poor connection, which affects the construction efficiency and quality stability. Summary of the Invention

[0008] Based on the existing technical problems in the splicing and installation of ALC wall panels, which are mostly carried out manually, resulting in low efficiency of manual handling, difficulty in alignment and adjustment, danger of flipping operations, and discontinuous process connections, this invention proposes a high-precision splicing and installation method for ALC wall panels.

[0009] This invention proposes a high-precision splicing and installation method for ALC wall panels, comprising the following steps:

[0011] Step 2: Positioning and Laying Out: After cleaning the floor and wall surfaces, lay out the axis lines, wall panel positions, and vertical panel joint control lines according to the drawings, and mark the elevation control lines to ensure that the panel joint positions are consistent vertically.

[0012] Step 3: Wall panel transportation and positioning: The wall panel is picked up by the mobile device and flipped so that it is perpendicular to the ground; the mobile device moves the clamped wall panel to the installation position, adjusts the position of the wall panel to align with the installation line, and pushes the wall panel to the predetermined installation position, with the mobile device assisting in the sliding.

[0013] Step 4: Wall panel adjustment and fixing: Use a measuring ruler to measure the flatness and verticality of the wall panel, fine-tune it to meet the requirements with a mobile device, then weld and fix it, connect the wall panel embedded parts to the main structure, and apply anti-rust paint.

[0014] Step 5: Joint Treatment: After cleaning the joints, insert polystyrene strips, fill with expanded cement mortar, fill with PE rods or polyurethane foam, and finally apply building sealant.

[0015] Step 6: Treatment of bottom joint and gable wall joint: After pouring fine stone concrete, apply cement mortar. After the strength is reached, apply polyurethane waterproof coating or building sealant. Fill the reserved joint with PE rod and seal it.

[0016] Step 7: Filling gaps: Fill with steel wire mesh sandwich panels of the same material as the wall panels, apply cement mortar to both sides, and apply sealant to the joints;

This not only greatly reduces the labor intensity of manual handling and avoids damage to the corners of the wall panels, but also achieves efficient and safe connection from transportation to positioning.

By setting up a mobile device with a clamping device and detection elements that have multi-dimensional adjustment functions, high-precision installation and adjustment of the wall panels are achieved, ensuring the overall construction quality. After the wall panels are in place, the clamping device of the mobile device, together with distance and tilt sensors, can accurately detect and fine-tune the flatness and verticality of the wall panels. This overcomes the defects of poor alignment accuracy and uneven panel joints caused by relying on manual visual inspection and pry bar adjustment in traditional construction. At the same time, combined with the subsequent standard panel joint and bottom joint treatment process, it ensures that the axis, panel joints and wall flatness of the wall panel installation meet the design requirements. This solves the technical problems of low efficiency of manual handling, difficulty in alignment and adjustment, danger of flipping operations and discontinuous process connection in the existing ALC wall panel splicing and installation process, which is mostly done manually.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Reference Figures 1-8 A high-precision splicing and installation method for ALC wall panels includes the following steps:

[0043] Step 1: Construction Preparation: Before installing ALC wall panels, comprehensive preparations are necessary. Prepare all required machinery and tools, including specialized mobile equipment, measuring rulers, welding equipment, etc., ensuring all tools are in good working order. Strictly inspect the incoming ALC wall panels, verifying that their specifications, dimensions, strength grade, and appearance quality meet design requirements. Also, verify product certificates, test reports, and other documentation. Accepted wall panels should be categorized and stacked on dedicated storage racks. These racks should be stable and reliable, and the stacking angle and position of the wall panels should meet requirements to prevent deformation or edge damage due to improper stacking.

[0044] Step Two: Positioning and Laying Out: First, clean the floor surface of loose dust and debris from the walls to ensure a clean and flat base. Then, according to the construction drawings, use surveying tools such as a theodolite and level to accurately lay out the wall axis, wall panel installation position lines, and vertical panel joint control lines on the floor. Simultaneously, mark elevation control lines on the wall columns as the basis for controlling the wall panel installation height. During the laying out process, ensure that each control line is accurately positioned, clearly marked, and that the vertical panel joint control lines are consistent vertically, providing a benchmark for the subsequent precise installation of the wall panels.

[0045] Step 3: Wall Panel Transportation and Positioning: The operator maneuvers the mobile equipment to the wall panel storage rack and uses the equipment's clamping device to pick up the wall panel. When clamping the wall panel, the clamping position should be adjusted according to the panel's size to ensure a secure and reliable grip. The wall panel is then smoothly flipped from a horizontal storage position to a vertical installation position. The speed should be controlled during the flipping process to avoid shaking or collisions. After the wall panel is flipped and erected, the mobile equipment carries it to the installation location. The position of the wall panel is adjusted using the equipment's lifting and translation functions, aligning the bottom of the wall panel with the installation line on the floor. The wall panel is then pushed to the designated installation position. During positioning, the mobile equipment can assist in sliding the wall panel to reduce frictional resistance.

[0046] Step 4: Wall Panel Adjustment and Fixing: Use a measuring ruler to measure the flatness and verticality of the wall panels, check whether the wall panels are flush with adjacent wall panels and whether the panel joints are uniform. If there are deviations, make fine adjustments using the multi-dimensional adjustment function of the mobile device until the flatness and verticality of the wall panels meet the specifications. After adjustment, immediately weld and fix the wall panel embedded parts to the embedded parts of the main structure. The weld should be full and continuous. After welding, clean the welding slag and apply anti-rust paint to the weld to prevent rusting.

[0047] Step 5: Joint Treatment: First, clean the dust and debris from the joints. Then, insert polystyrene strips into the joints as a backing material. Next, fill the joints with expanding cement mortar, compacting and smoothing it to ensure it is full and dense. After the mortar has initially set, fill the outside of the joints with PE rods or expanded polyurethane foam. Finally, apply building sealant to the surface, smoothing and compacting it to ensure a tight seal and a smooth surface.

[0048] Step Six: Special treatment is required for the bottom joints between the wall panels and the floor, as well as the joints in the gable walls. For the bottom joints, first pour fine aggregate concrete, then vibrate and compact it, and smooth it. After the concrete reaches a certain strength, apply a layer of cement mortar to level it. After the mortar dries, apply polyurethane waterproof coating or building sealant to the surface of the joint. For pre-reserved expansion joints, first fill them with PE rods, then seal them with sealant to ensure waterproofing.

[0049] Step Seven: Gap Filling: When gaps arise during construction due to pre-reserved openings or construction errors, they must be filled. Use wire mesh sandwich panels of the same material as the wall panels as the filling material. Cut appropriately sized filling panels according to the gap dimensions and embed them into the gap. Apply cement mortar to both sides of the filling panels, ensuring the plaster layer is smooth and blends naturally with the surrounding wall panels. Apply sealant to the joints between the filling panels and the existing wall panels to ensure integrity and a tight seal.

[0050] Step Eight: Quality Inspection and Finished Product Protection: Finally, conduct a quality inspection and protect the finished product. Perform a comprehensive quality inspection of the installed wall panels, including verticality, flatness, joint width, sealing quality, and weld strength, ensuring compliance with design requirements and construction specifications. Simultaneously, implement protective measures around the wall panels, such as affixing corner protectors and setting up warning signs, to prevent damage from collisions during subsequent construction. Regularly inspect the installed wall panels and address any problems promptly.

[0051] like Figure 1 As shown, the mobile device in step one mainly consists of a mobile vehicle component 1, an auxiliary roller group 11, an adjustment device, and a clamping device.

[0052] The auxiliary roller assembly 11 is slidably inserted into the lower end of the lifting guide rail of the mobile vehicle component 1. After the auxiliary roller assembly 11 is pulled out, the rollers on the auxiliary roller assembly 11 can rotate, which facilitates the movement of the wall panel to complete the splicing.

[0053] The mobile vehicle component 1 is the foundation for the movement and support of the entire equipment. It is equipped with wheels at the bottom and can be driven by power to move the equipment flexibly on the construction site. The mobile vehicle component 1 is equipped with vertical lifting guide rails and lifting components, which are used to drive the adjustment device to rise and fall along the guide rails, thereby adjusting the height of the clamping device, similar to the lifting components of a forklift.

[0054] This component provides mobility and a lifting base for the entire equipment, allowing it to move freely between the wall panel stacking area and the installation work surface. This solves the problem of relying on manual handling or separate hoisting equipment for wall panel transportation in traditional construction. The result is rapid wall panel transfer, reduced process connection time, and prevention of edge and corner damage caused by multiple transfers.

[0055] like Figures 2-3 As shown, the adjustment device is the core transition mechanism connecting the mobile vehicle component 1 and the clamping device, and undertakes the key function of adjusting the posture of the wall panel. The adjustment device includes multiple components such as the slide 2, the drive rotating seat 21, the rotating ring 23, the tilting hydraulic cylinder 24, the rotating frame 22, the adjustment housing 25, and the tilting linkage 26, which together constitute a multi-degree-of-freedom adjustment system.

[0056] The slide 2 is the basic frame of the adjustment device. Its two ends slide in cooperation with the lifting guide rail of the moving vehicle component 1. Driven by the lifting component of the moving vehicle component 1, it can make a smooth vertical lifting and lowering movement along the guide rail. The function of the slide 2 is to realize the height adjustment of the clamping device, which facilitates the flipping and moving of the wall panel.

[0057] The drive rotating seat 21 is fixedly installed on the outer surface of the slide 2, and consists of a rotating seat and a rotary motor fixedly installed on the rotating seat; a rotating frame 22 is fixedly installed at one end of the output shaft of the rotary motor, and the rotating frame 22 can rotate around the horizontal axis under the drive of the rotary motor; the function of the drive rotating seat 21 is to provide a horizontal rotation function for the clamping device, so that the wall panel can be adjusted in the horizontal plane; it is convenient to flip the clamped wall panel so that it can be changed from a horizontal state to a vertical state.

[0058] A rotating ring 23 is rotatably connected to the outer surface of the drive rotating base 21. A tilting hydraulic cylinder 24 is hinged to the outer surface of the rotating ring 23 via a pin. An adjusting housing 25 is hinged to the outer surface of the rotating frame 22 via a pin. A tilting connecting rod 26 is fixedly installed on the outer surface of the adjusting housing 25. One end of the tilting connecting rod 26 is hinged to one end of the piston rod of the tilting hydraulic cylinder 24 via a pin. This forms a four-bar linkage. When the tilting hydraulic cylinder 24 extends or retracts, it drives the adjusting housing 25 to swing around the rotating frame 22 via the tilting connecting rod 26. The function of this mechanism is to realize the tilting function of the clamping device, allowing the wall panel to be smoothly tilted from a horizontal storage state to a vertical installation posture. This completely solves the problems of poor stability and high safety hazards of traditional manual tilting operations. The tilting process is smooth and controllable, effectively protecting the wall panel from damage.

[0059] like Figures 3-8 As shown, the adjusting housing 25 is the part of the adjusting device that is directly connected to the clamping device; the clamping device includes a movable clamping housing 3, a lifting clamping housing 32, a pushing hydraulic cylinder 31, a lifting hydraulic cylinder 33, a rotating rod 34, a moving motor 35, a rotating shaft 36, a lifting motor 37, and a clamping mechanism.

[0060] One end of the adjusting housing 25 is slidably inserted into the movable clamping housing 3. A hydraulic cylinder 31 is fixedly installed on the outer surface of the adjusting housing 25, with one end of the piston rod of the hydraulic cylinder 31 fixedly connected to the outer surface of the movable clamping housing 3. By extending or retracting the hydraulic cylinder 31, the movable clamping housing 3 can be driven to move horizontally relative to the adjusting housing 25 to clamp the wall panel. The other end of the adjusting housing 25 is slidably inserted into one end of the lifting clamping housing 32. The upper surface of the adjusting housing 25 is fixedly installed with the lifting hydraulic cylinder 33, with one end of the piston rod of the lifting hydraulic cylinder 33 fixedly connected to the outer surface of the lifting clamping housing 32. By extending or retracting the lifting hydraulic cylinder 33, the lifting clamping housing 32 can be driven to move vertically up or down relative to the adjusting housing 25, facilitating the clamping mechanism on the lifting clamping housing 32 to leave the wall panel and facilitating splicing on one side of the wall panel.

[0061] The design functions of the movable clamping housing 3 and the lifting clamping housing 32 are to enable the wall panel to be clamped by moving the movable clamping housing 3, and to release the clamping on one side of the wall panel by moving the lifting clamping housing 32, so as to facilitate the splicing of the wall panel.

[0062] The movable clamping housing 3 is rotatably connected to both ends of the rotating rod 34 via bearings. Two rotating rods 34 are typically provided, arranged parallel to each other within the two movable clamping housings 3. The inner wall of the movable clamping housing 3 is fixedly mounted to the outer surface of the movable motor 35. One end of the output shaft of the movable motor 35 is fixedly connected to one end of one of the rotating rods 34. The other end of this rotating rod 34 and one end of the other rotating rod 34 are linked together via a synchronous pulley and a synchronous belt. When the movable motor 35 starts, it drives the two rotating rods 34 to rotate synchronously. The function of this structure is to provide a power source for the clamping mechanism inside the movable clamping housing 3 and to ensure that the two rotating rods 34 rotate at the same speed. The effect is to make the clamping action smooth and synchronous, avoiding uneven force on the wall panel due to asynchrony on both sides, which could lead to tilting or damage.

[0063] The internal structure of the lifting clamping housing 32 is similar to that of the movable clamping housing 3, with two rotating shafts 36 connected to it via bearings. The outer surface of the lifting clamping housing 32 is fixedly mounted to the outer surface of the lifting motor 37. One end of the output shaft of the lifting motor 37 is fixedly connected to one end of one of the rotating shafts 36, and drives the other rotating shaft 36 to rotate synchronously via a synchronous belt and a synchronous pulley. The function of the lifting motor 37 is to provide power to the clamping mechanism inside the lifting clamping housing 32, thereby achieving the vertical clamping or releasing of the wall panel.

[0064] The core of the clamping device is the clamping mechanism, which consists of two sets, each composed of two mechanisms, located inside the two movable clamping housings 3 and the two lifting clamping housings 32, respectively. Each clamping mechanism includes a transmission gear 4, a gear set 41, a transmission worm gear 42, a drive gear 43, and multiple movable clamping plates 44.

[0065] The transmission gear 4, located inside the movable clamping housing 3, has its inner wall slidably inserted into the outer surface of the rotating rod 34. It can both rotate with the rotating rod 34 and slide axially on the rotating rod 34 to adapt to changes in the clamping position. The transmission gear 4, located inside the lifting clamping housing 32, has its inner wall fixedly connected to the outer surface of the rotating shaft 36 and rotates synchronously with the rotating shaft 36.

[0066] Both the lifting clamping housing 32 and the moving clamping housing 3 have a gear set 41 rotatably connected to their inner walls via bearings. The gear set 41 consists of meshing gears and a worm gear. The gear portion of the gear set 41 meshes with the transmission gear 4, transmitting the rotational motion of the rotating rod 34 or the rotating shaft 36 to the gear set 41. The worm gear portion of the gear set 41 meshes with one end of the transmission worm 42, converting the rotational motion into the rotation of the transmission worm 42.

[0067] The other end of the transmission worm gear 42 is connected to the drive gear 43 via a synchronous belt and a synchronous pulley, driving the drive gear 43 to rotate. The drive gear 43 meshes with the toothed groove on the inner side of the movable clamping plate 44, and the outer surface of the movable clamping plate 44 slides against the inner wall of the outer shell. When the drive gear 43 rotates, the meshing action of the toothed groove pushes the movable clamping plate 44 to move inward along the guide groove, thereby clamping the wall panel.

[0068] The function of this gear transmission mechanism is to convert the rotational motion of the motor into the linear clamping motion of the moving clamping plate 44, thus providing the supporting force for the initial clamping of the wall panel and the clamping force after the wall panel is flipped. The result is a firm and reliable clamping, capable of stably gripping heavy ALC wall panels, while the clamping force is evenly distributed, avoiding excessive localized force that could damage the wall panel surface.

[0069] The inner walls of the movable clamping housing 3 and the lifting clamping housing 32 are rotatably connected to a lifting screw 5 via a bearing seat. One end of the transmission worm gear 42 drives the lifting screw 5 to rotate via a bevel gear set 41. The outer surface of the lifting screw 5 is threadedly connected to the inner wall of the lifting clamping plate 51. The inner wall of the lifting clamping plate 51 is slidably inserted into the inner wall of the housing. Rotating the lifting screw 5 can drive the lifting clamping plate 51 to move up and down in the vertical direction.

[0070] The lifting screw 5 and the lifting clamping plate 51 work together with the movable clamping plate 44 to clamp and limit the wall panel when it is clamped. After the wall panel is supported by the movable clamping plate 44, the lifting screw 5 can be adjusted to lower the lifting clamping plate 51, which then contacts the upper surface of the wall panel to clamp it. This increases the stability of the wall panel in the clamped state and prevents it from slipping or shaking due to a shift in the center of gravity during flipping or transportation.

[0071] A distance sensor 6 and a tilt sensor 61 are fixedly installed on the upper part of the adjusting housing 25 via a support frame. The distance sensor 6 is used to detect the distance between the wall panel and the adjusting housing 25, thereby determining the distance to the clamping point on the moving clamping housing 3 and the lifting clamping housing 32. The clamping point is based on the surface formed by the contact between the outer surfaces of the upper and lower ends of the lifting clamping housing 32 and the moving clamping housing 3 and the upper surface of the moving clamping plate 44. The clamping point contacts the lowest edge of the side of the wall panel. The tilt sensor 61 is used to monitor the verticality of the wall panel after clamping in real time. The function of these sensors is to provide operators with accurate position and posture data, changing the outdated method of simply relying on visual inspection and manual adjustment. The effect is to realize the digital and precise control of wall panel installation, greatly improve installation accuracy, ensure that the flatness and verticality of the wall panel meet the specifications at one time, and reduce the workload of repeated adjustments.

[0072] Working principle: When the equipment is in standby mode, the mobile vehicle component 1 serves as the base to support the entire equipment. When the operator starts the power system, the walking wheels drive the equipment to the side of the wall panel storage rack. The lifting guide rail and lifting components on the mobile vehicle component 1 are at their initial height, ready to dock with the wall panel. The function of the mobile vehicle component 1 is to provide the mobility and support foundation for the entire system, enabling it to move freely between the stacking area and the working surface.

[0073] After the equipment arrives at the storage rack position, clamping preparation begins. At this time, the slide 2 in the adjustment device moves along the lifting guide rail under the drive of the lifting component, adjusting the overall height of the clamping device so that the clamping device is roughly aligned with the middle of the wall panel.

[0074] Subsequently, the hydraulic cylinder 31 is activated, its piston rod extends, driving the movable clamping housing 3 to move horizontally relative to the adjusting housing 25, bringing the movable clamping housing 3 closer to the side of the contact wall panel. The cooperation between the movable clamping housing 3 and the lifting clamping housing 32 clamps the wall panel. The moving carriage component 1 drives the slide 2 to rise, and after the clamped wall panel rises a certain distance, the lifting motor 37 and the moving motor 35 start. After the rotating shaft 36 and the rotating rod 34 rotate, they drive the transmission gear 4 to rotate. The transmission gear 4 meshes with the gear set 41, causing the gear set 41 to rotate and drive the transmission gear 4 to rotate. The worm gear 42 rotates, and one end of the worm gear 42 is connected to the drive gear 43 through a synchronous belt and a synchronous pulley, driving the drive gear 43 to rotate. The drive gear 43 meshes with the tooth groove on the inner side of the movable clamping plate 44, and the movable clamping plate 44 moves to the lower surface of the wall panel to support the wall panel. At the same time, the rotation of the worm gear 42 is transmitted, and the lifting screw 5 is driven to rotate through the transmission of the bevel gear set 41. The lifting screw 5 drives the lifting clamping plate 51, which is threaded to it, to descend and contact the upper surface of the wall panel. The cooperation of the lifting clamping plate 51 and the movable clamping plate 44 completes the clamping of the wall panel.

[0075] After the wall panel is securely clamped, a flipping operation is performed to change it from a horizontal state to a vertical installation position. The flipping hydraulic cylinder 24 starts to move, and its piston rod retracts. When the flipping hydraulic cylinder 24 moves, it drives the adjusting housing 25 to swing around the rotating frame 22 through the flipping connecting rod 26. As the adjusting housing 25 swings, the clamping device as a whole, together with the clamped wall panel, gradually flips from a horizontal state until it reaches a position perpendicular to the ground.

[0076] Start the rotary motor inside the drive rotary seat 21. The rotary motor drives the rotary frame 22 to rotate around the horizontal axis. Since the adjusting housing 25 is hinged to the rotary frame 22, the rotation of the rotary frame 22 will drive the entire clamping device and wall panel to rotate in the horizontal plane, thereby achieving orientation adjustment. The tilting hydraulic cylinder 24 rotates on the drive rotary seat 21 through the rotating ring 23 to ensure that the wall panel can be erected at the correct angle.

[0077] When the mobile carriage component 1 is activated, it moves the clamped wall panel to the required splicing position. The tilt sensor 61 determines the posture of the clamped wall panel and makes fine adjustments to ensure that the clamped wall panel is perpendicular to the ground. Then, the auxiliary roller group 11 is manually pulled out and positioned below the required splicing position. After the slide 2 descends, the lower surface of the wall panel contacts the rollers of the auxiliary roller group 11. The clamping mechanism inside the lifting clamping housing 32 is activated, causing the moving clamping plate 44 and the lifting clamping plate 51 to reset. After the piston rod of the lifting hydraulic cylinder 33 retracts, it drives the lifting clamping housing 32 to rise, causing the lifting clamping housing 32 to move away from one side of the wall panel, releasing the clamping on one side of the wall panel. The wall panel is kept stable by the clamping on the other side and the support of the auxiliary roller group 11 below. By pushing the hydraulic cylinder 31, the moving clamping housing 3 moves. After the wall panel moves on the auxiliary roller group 11, it moves closer to the splicing side, completing the splicing work.

[0078] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
