Abstract

This invention relates to the field of construction engineering technology, specifically to a prefabricated construction method for a tall, spacious interior aluminum panel ceiling in an antique-style building. A BIM model is established to modularize the framework and surface layer, ensuring quality while accelerating construction progress. During the framework hoisting process, a central hoisting seat, a left sheave, and a right sheave are installed on the roof. The central hoisting seat serves as the fixing point for the side traction ropes, which extend to both sides. The side traction ropes extend to the ground via the left and right sheaves and connect to side winches on the ground. The side winches retract the side traction ropes, fixing the central traction rope to the inside of the main structure. Simultaneously, the central and side winches are activated according to their corresponding power levels, slowly lifting the main structure to a higher position. After the side traction ropes are taut, an adjustment line is formed. The central traction rope is removed, and the position of the main structure is adjusted laterally along the adjustment line, aligning the installation nodes of the hoisting unit and the main structure with the main hoist, facilitating adjustments to the main structure's position at high altitudes.

Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, specifically to a prefabricated construction method for aluminum panel ceilings with a tall, open interior space design in antique-style buildings. Background Technology

[0002] As people's living standards continue to improve, their demand for spiritual and cultural enrichment is also increasing, leading to a booming tourism industry. Consequently, tourist attractions with Chinese ancient cultural themes are proliferating, and more and more antique-style buildings are springing up. The beams, brackets, interior ceilings, coffered ceilings, and column heads feature meticulously crafted designs that seamlessly integrate composition and component shapes, showcasing exquisite artistry and rich colors. To preserve historical and traditional culture and achieve an antique-style wooden ceiling structure, modern decoration often utilizes transfer-printed wood grain aluminum panels for interior ceiling construction.

[0003] In the construction of tall interior spaces for antique-style buildings, it is necessary to lift large skeletal structures to a high position. The existing hoisting method is a multi-section hoisting structure. This structure requires adjusting the posture after the skeletal structure is lifted to a high position. Due to the limitations of hoisting, the adjustment of the skeletal structure is relatively difficult. It often takes a lot of time to match the skeletal structure with the hanging rods. The construction is difficult and the structural stability is poor, which cannot meet people's needs. Therefore, it is necessary to study a prefabricated construction method for aluminum panel ceilings for tall interior spaces in antique-style buildings. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a prefabricated construction method for aluminum panel ceilings with tall interior spaces in antique-style buildings, which effectively solves the problems of difficult construction during the hoisting process of existing frames, especially the difficulty of adjusting the posture at high altitudes and the low construction efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this invention is: a prefabricated construction method for aluminum panel ceilings with antique-style interior high-ceiling designs, comprising the following steps:

[0006] Step 1, Measure and Lay Out

[0007] Starting from the original surveying and setting-out observation points of the civil engineering, the key parts of the decoration project are surveyed and set out.

[0008] Step 2, BIM Model Creation

[0009] A 3D scanner was used to measure the construction site, and the measurement data was collected and replicated in real time. High-precision reverse modeling was performed on the parts that needed to be constructed, and the data was archived.

[0010] Based on the comparison between the on-site measurement data collected in step one and the dimensions of the BIM model, and taking into account the installation dimensions and positions of the installed equipment, pipes, supports and terminals on site, the final dimensions of the BIM model are adjusted.

[0011] Step 3: Fabrication of the keel and surface aluminum panels

[0012] Based on the BIM-confirmed model drawings, export the optimized skeleton and surface material drawings, and calculate the skeleton dimensions separately for each unit ceiling. Mark the unit positions for units with the same dimensions.

[0013] Step 4: Creating the Transition Layer

[0014] Based on the ground control axis and the fixed points of the transition layer on the construction drawings, a laser vertical instrument is used to guide the fixed points on the roof. According to the construction drawings and the site conditions, the anchoring parts of the transition layer frame are optimized, and the hangers are fixed on the roof. The hangers include main hangers and auxiliary hangers. The main hangers are used to fix and hoist the frame, and the auxiliary hangers are used to fix the hoisting fixtures. The hoisting fixtures include a central hanger, a left hanger wheel, and a right hanger wheel. The central hanger, the left hanger wheel, and the right hanger wheel are at the same level, and a side winch is arranged on the ground at the same level. A side traction rope is fixed to the side of the central hanger. The side traction rope is connected to the side winch on the ground through the corresponding side hanger wheel. A central hanger wheel is set at the bottom of the central hanger. The central hanger wheel has a double wheel structure. A central winch corresponding to the central hanger wheel is set on the ground. The rope wheel of the central winch has a double wheel structure and can synchronously wind up the central traction ropes on both sides. The central traction rope passes around the central hanger wheel, and its two ends are connected to the hoisting frame and the central winch, respectively.

[0015] Step 5: Fabrication of the keel frame unit blocks

[0016] According to the skeleton drawings, the unit block panels are manufactured. Each unit block panel includes a main structure and a hoisting part. The main structure is provided with a hoisting part, which is provided with rope holes. The side traction rope can enter the rope holes and the main structure is lifted under the traction of the winch. The upper part of the hoisting part is provided with a fixing plate, and the bottom of the main hoisting rod is provided with a connecting plate that corresponds to the fixing plate. A connecting hole is provided between the fixing plate and the connecting plate. The fixing plate and the connecting plate are fixedly assembled together by adding bolts.

[0017] The surface layer is made according to the surface material drawings; after the components are made, they are transported to the corresponding ceiling positions and arranged and spot-welded according to the finished lines of the floor and ceiling. After the spot welding is completed, the deviation of the frame is checked in time. After there are no errors, the full welding stage is started.

[0018] Step 6: Hoist and secure the unit panels.

[0019] First, lower the side traction rope between the side sheave and the central hoisting seat, slip the side traction rope into the rope hole, and seal the rope hole with bolts. Then, fix the central traction rope to the inside of the main structure. At the same time, start the central winch and side winch according to the corresponding power to slowly lift the main structure to a high position. After the side traction rope is taut, an adjustment line is formed. Remove the central traction rope and adjust the position of the main structure laterally along the adjustment line so that the installation nodes of the hoisting part and the main structure correspond to the main hoisting rod. Fix the main structure to the hoisting rod. Finally, remove the side traction rope.

[0020] Step 7, Fix the surface layer

[0021] Based on the numbers on the aluminum plate numbering diagram, locate the corresponding aluminum plate numbers on site and use an electric lifting platform to install the surface layer sequentially from top to bottom.

[0022] Furthermore, the rope hole has an arc-shaped structure, with a guide inlet at its lower part, and a bolt is installed inside the guide inlet.

[0023] Furthermore, the main structure includes horizontal ribs, connecting ribs, reinforcing ribs, and mounting plates. The horizontal ribs are arranged at intervals and connected ribs are provided at their ends. The mounting plates are located between two adjacent horizontal ribs and are fixed to the connection between the horizontal ribs and the connecting ribs by the reinforcing ribs.

[0024] Furthermore, a hoisting section is provided in the middle of the main structure. The hoisting section includes a fixed base and a reinforcing plate. The fixed base is fixed in the middle of the main structure by the reinforcing plate. Fixed sections corresponding to the hoisting section are provided on both sides of the main structure. Fixed plates corresponding to the main lifting rods are provided on the fixed sections.

[0025] Furthermore, the fixing part and the hoisting part are arranged in a staggered and cross manner.

[0026] The beneficial effects of the above technical solution are as follows: In response to the existing problem of difficult frame hoisting construction, this invention uses a 3D scanner to accurately measure the site, accurately lay out the dimensions of the shaped aluminum panels on site, use BIM technology to build a model, standardize the dimensions of the keel frame and aluminum panels of the same size, place accurate orders in batches, and then process them in batches at the processing plant. The components of the keel frame are welded into individual unit panels according to the model dimensions, and then the keel frame unit panels are hoisted as a whole to the corresponding positions on the ceiling and fixed firmly. Finally, the pre-processed aluminum panels are installed.

[0027] During the hoisting of the frame, a central hoisting seat, a left sheave, and a right sheave were installed on the roof. The central hoisting seat served as the fixing point for the side traction ropes, which extended to both sides. The side traction ropes extended to the ground via the left and right sheaves and connected to the side winches on the ground. The side winches were used to wind up the side traction ropes. First, the side traction ropes between the side sheaves and the central hoisting seat were lowered, then the ropes were threaded into the rope holes and sealed with bolts. Next, the central traction rope was fixed to the inside of the main structure. Simultaneously, the central and side winches were started according to their corresponding power levels, allowing the main structure to slowly... Slowly lift to a high position; after the side traction rope is taut, an adjustment line is formed. Remove the middle traction rope and adjust the position of the main structure laterally along the adjustment line so that the installation nodes of the hoisting part and the main structure correspond to the main hoist. Fix the main structure to the hoist. Finally, remove the side traction rope and use the shortening of the side traction rope to lift the main structure upward. Use the middle traction rope to pull the main structure to one side laterally, so that the main structure can be pulled smoothly on the side traction rope. When the side traction rope is taut, it allows the main structure to move on the side traction rope and adjust its position, which is convenient for adjusting the position of the main structure at high altitude.

[0028] Therefore, the present invention has a novel structure, which facilitates the adjustment of the frame position at high altitudes, reducing construction difficulty. At the same time, the main structure of the present invention is equipped with distributed fixed hoisting points, which provides high hoisting strength, high structural stability, and high construction efficiency. By measuring and setting out lines and establishing a BIM model, the frame and surface layer are modularized, which accelerates the construction progress while ensuring quality. The standardized processing in the back-end ensures high precision and speed of component processing. The overall prefabricated installation results in fast construction speed, high precision, short construction period, and high economic benefits. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0037] Example 1: This example aims to provide a prefabricated construction method for aluminum panel ceilings with large interior spaces in antique-style buildings. It is mainly used for the prefabricated construction of aluminum panel ceilings with ultra-large interior spaces. Addressing the problems of existing construction structures, such as the difficulty in adjusting the frame posture during hoisting and low construction efficiency, this example provides a BIM-based prefabricated construction method for aluminum panel ceilings with large interior spaces in antique-style buildings. This example can be widely applied to aluminum panel ceilings and wall decoration projects with arrayed large interior spaces in various public buildings and stadiums. It also has reference value for curtain wall decoration projects with similar structures.

[0038] Specific details are as follows Figure 6 The construction process flowchart shown in the image illustrates a prefabricated construction method for aluminum panel ceilings in a tall, antique-style interior space, comprising the following steps:

[0039] Step 1, Measure and Lay Out

[0040] Starting from the original surveying and setting-out observation points of the civil engineering, the key parts of the decoration project are surveyed and set out. First, the necessary tools for construction are prepared, and the construction drawings, BIM model, relevant construction atlases, technical quality standards, and various internal documents are prepared.

[0041] The surveying and setting out process involves expanding upon the original surveying and setting out observation points provided by the civil engineering unit, such as the grid control lines and elevation benchmarks. Then, the key parts of the decoration project (the finished lines of the main decorative surfaces) are surveyed and set out.

[0042] Elevation control: The original building elevation benchmark is transferred to the column surfaces between floors, and then the floor elevation is transferred to the side of the beam using a level. The elevation points should be transferred from the original civil engineering benchmark point layer by layer to avoid the accumulation of errors.

[0043] Horizontal dimension control: Based on the original building coordinate benchmark, the benchmark is transferred to each floor using a total station, theodolite, and level, and the construction axis is marked. Then, the position of the decoration control line is simulated using CAD software to ensure that the control line is convenient for construction. Finally, the decoration construction ceiling line is laid out on the construction site.

[0044] On the floor where construction is required, based on the simulated control line position, a theodolite and ink cartridge are used to mark out a rectangular enclosure and ink lines in the south, north, east, and west directions to form a horizontal control baseline. Using the horizontal control line and axis, combined with the drawings, the ceiling finish line is marked out. Based on the equipment points marked on the CAD blueprint (such as sprinklers, smoke detectors, sound systems, etc.), the points are then positioned and sprayed one by one on site.

[0045] Step 2, BIM Model Creation

[0046] A 3D scanner was used to measure the construction site, and the measurement data was collected and replicated in real time. High-precision reverse modeling was performed on the parts that needed to be constructed, and the data was archived.

[0047] Based on the comparison between the on-site measurement data collected in step one and the dimensions of the BIM model, and taking into account the installation dimensions and positions of the installed equipment, pipes, supports, and terminals on site, the final dimensions of the BIM model are adjusted.

[0048] Using a 3D scanner, precise data on the current construction status of the civil engineering site was collected and replicated. High-precision reverse modeling was then performed on the parts requiring construction, providing the latest and most accurate data for the subsequent detailed design of the roof surface, and the data was archived. The collected on-site measurement data was then compared with the dimensions of the BIM model, and the final dimensions of the model were adjusted based on the installation dimensions and locations of the installation unit's equipment, pipes, supports, and terminals.

[0049] By using software such as Revit and ArchiCAD to build BIM models, the design results can be dynamically visualized, and 3D models can be viewed online, allowing on-site workers to intuitively understand the design scheme. The models can guide on-site workers in batch processing of the skeleton and the subsequent aluminum plate processing, accurately providing simulation scenario data for steel skeleton connection points, batch order dimensions of skeleton components, skeleton unit welding, and installation methods.

[0050] Due to the complex design of the ceiling in antique-style buildings, the processing of the steel keel structure and the aluminum surface panels must be customized to ensure high-quality production and accurate delivery and installation. BIM's 3D construction model provides processing companies with precise production dimensions, providing accurate data for the fully digital prefabricated building materials production industry, ensuring quality, accurate delivery time, and on-site installation accuracy.

[0051] Step 3: Fabrication of the keel and surface aluminum panels

[0052] Based on the BIM-confirmed model drawings, export the optimized skeleton and surface material drawings, and calculate the skeleton dimensions separately for each unit ceiling. Mark the unit positions for units with the same dimensions.

[0053] Based on the BIM-confirmed model drawings, optimized CAD drawings of the framework and surface materials are exported. Using software, the framework dimensions are counted separately for each ceiling unit, and units with the same dimensions are marked to ensure accurate material cutting for the unit framework. The quantities of aluminum panels of the same specifications and sizes are counted, such as stepped aluminum panels and rafters for coffered ceilings of the same specifications, and corbels, pendants, and brackets in the same area. After the count is completed, a one-time order is placed to ensure both order accuracy and efficiency.

[0054] Step 4: Creating the Transition Layer

[0055] Based on the ground control axis and the fixed points of the transfer layer on the construction drawings, a laser vertical instrument is used to guide the fixed points on the roof. According to the construction drawings and the site conditions, the anchoring parts of the transfer layer frame are optimized, and the hangers are fixed on the roof 1. According to the construction drawings and the site conditions, the anchoring parts of the transfer layer frame are optimized, and L80×40×4@1000mm double-hole angle brackets and hot-dip galvanized angle steel are used to ensure the stability of the frame.

[0056] The hoisting system includes a main hoisting rod 2 and an auxiliary hoisting rod 3. The main hoisting rod 2 is used to fix and hoist the frame, and the auxiliary hoisting rod 3 is used to fix the hoisting fixture. The hoisting fixture includes a central hoisting seat 5, a left sheave 4, and a right sheave 6. The central hoisting seat 5, the left sheave 4, and the right sheave 6 are at the same level, and a side winch 8 is arranged on the ground at the same level. A side traction rope 7 is fixed to the side of the central hoisting seat 4. The side traction rope 7 is connected to the side winch 8 on the ground via the corresponding side sheave. A central hoisting wheel 10 is set at the bottom of the central hoisting seat 5. The central hoisting wheel 10 has a double wheel structure. The rope wheel of the central winch has a double wheel structure and can synchronously wind up the central traction ropes on both sides. A central winch 11 corresponding to the central hoisting wheel 10 is set on the ground. The central traction rope 9 passes around the central hoisting wheel 10, and its two ends are connected to the hoisting frame and the central winch, respectively. The central winch can synchronously wind up the central traction ropes 9 on both sides.

[0057] Step 5: Fabrication of the keel frame unit blocks

[0058] According to the skeleton drawings, the unit blocks are made. Based on the order drawings, the required components of the same specifications and dimensions for the aluminum caisson ceiling are determined and the quantities are counted. A sample component is made and each component is numbered. The same specifications of components are mass-produced. Mass production, processing and welding are carried out according to the component mold. After welding, the welded parts are rust-proofed and sprayed with anti-rust paint. According to the site requirements, they are stacked neatly and in place.

[0059] In this embodiment, the unit block includes a main structure 12 and a hoisting part 16. The main structure 12 is provided with the hoisting part 16, which has a rope hole. The side traction rope 7 can enter the rope hole. The rope hole has an arc-shaped structure and a guide inlet 18 is provided at its lower part. A bolt 17 is provided in the guide inlet 18. The bolt 17 prevents the side traction rope 7 from coming out and allows it to enter the rope hole from the side, making it easy to disassemble when necessary.

[0060] The main structure 12 includes horizontal ribs 121, connecting ribs 122, reinforcing ribs 124, and mounting plates 123. The horizontal ribs 121 are arranged at intervals and connected ribs 122 are provided at their ends. The mounting plates 123 are located between two adjacent horizontal ribs 121 and are fixed at the connection between the horizontal ribs 121 and the connecting ribs 122 by the reinforcing ribs 124. A hoisting part 16 is provided in the middle of the main structure. Fixing parts 125 corresponding to the hoisting part 16 are provided on both sides of the main structure. Fixing plates corresponding to the main lifting rods are provided on the fixing parts 125. The fixing parts 125 and the hoisting parts 16 are arranged in a staggered and cross manner.

[0061] The main structure 12 is lifted under the traction of the side winch 8. The upper part of the hoisting part 16 is provided with a fixing plate 14, and the bottom of the main hoist 2 is provided with a connecting plate 13 corresponding to the fixing plate 14. A connecting hole is provided between the fixing plate 14 and the connecting plate 13. The fixing plate and the connecting plate are fixedly assembled together by adding connecting bolts 15.

[0062] The surface layer is fabricated according to the surface material drawings; the aluminum plate processing project is carried out in a standardized production according to the material list, and the quality of the finished product is strictly controlled. Irregular, extra-long and irregularly shaped aluminum plates are processed in sections and numbered one by one to ensure the on-site installation progress requirements and the traceability of the ceiling aluminum plates after installation. Each aluminum plate can be adjusted in time according to the number. After the components are fabricated, they are transported to the corresponding ceiling position and arranged and spot-welded according to the floor ceiling completion line. After the spot welding is completed, the frame deviation is checked in time. After there is no error, the full welding stage is entered.

[0063] Step 6: Hoist and secure the unit panels.

[0064] First, lower the side traction rope 7 between the side sheaves (left and right sheaves) and the central lifting base 5. Insert the side traction rope 7 into the rope hole and seal the rope hole with bolt 17. Then, fix the central traction rope 9 to the inside of the main structure 12. Simultaneously, start the central winch 11 and the side winch 8 according to the corresponding power to slowly lift the main structure 12 to a high position. After the side traction rope is taut, an adjustment line is formed. Remove the central traction rope and adjust the position of the main structure laterally along the adjustment line so that the installation nodes of the hoisting part and the main structure correspond to the main lifting rod. Fix the main structure to the lifting rod. Finally, remove the side traction rope.

[0065] Step 7, Fix the surface layer

[0066] Based on the numbers on the aluminum plate numbering diagram, locate the corresponding aluminum plate numbers on site and use an electric lifting platform to install the surface layer sequentially from top to bottom.

[0067] Therefore, this embodiment utilizes BIM technology to establish a model, standardizes the dimensions of the keel frame and aluminum panels of the same size, and places accurate orders in batches. Then, batch processing is carried out at the manufacturing plant, welding the keel frame components into individual unit panels according to the model dimensions. The keel frame unit panels are then hoisted and securely fixed to the corresponding positions on the ceiling. Next, the pre-processed aluminum panels are installed. During the frame hoisting process, a central hoisting seat, a left sheave, and a right sheave are set on the roof. The central hoisting seat serves as the fixing point for the side traction ropes, extending the side traction ropes to both sides. The side traction ropes extend to the ground through the left and right sheaves and connect to side winches on the ground. The side winches can reel in the side traction ropes. First, the side traction rope between the side sheave and the central hoisting seat is lowered, and the side... The traction rope is inserted into the rope hole and sealed with bolts. Then, the central traction rope is fixed to the inside of the main structure. Simultaneously, the central winch and side winch are started according to the corresponding power to slowly lift the main structure to a high position. After the side traction rope is taut, an adjustment line is formed. The central traction rope is removed, and the position of the main structure is adjusted laterally along the adjustment line so that the installation nodes of the hoisting part and the main structure correspond to the main boom. The main structure is then fixed to the boom. Finally, the side traction rope is removed, and the shortening of the side traction rope is used to lift the main structure upward. The central traction rope is used to pull the main structure to one side, allowing the main structure to move smoothly on the side traction rope. When the side traction rope is taut, it allows the main structure to move on the side traction rope and adjust its position, facilitating the adjustment of the main structure's position at high altitudes.
