Description

Technical Field

[0001] The invention relates to the technical field of ALC board construction, and more specifically to a construction method of an ALC board with special-shaped super-high exterior wall. Background Art

[0002] With the rapid development of the construction industry and technological advancement, ALC board (Autoclaved Lightweight Concrete) as a new type of building material has been widely used in complex building structures such as ultra-high exterior wall special-shaped shapes due to its light weight, high strength, thermal insulation, heat insulation, sound insulation and other excellent properties.

[0003] However, the traditional ALC board construction method has problems such as low construction efficiency and poor precision when constructing super-high exterior wall special-shaped shapes, which is difficult to meet the high requirements and fast pace of modern buildings. The main factor is that the ALC boards in different positions required for the super-high exterior wall special-shaped shapes are of different shapes. At the construction site, not every construction worker is prepared to understand the installation position of each ALC board, that is, when installing ALC boards of different shapes, special guidance is required, which reduces the construction efficiency. At the same time, since the exterior wall is a super-high structure, if the installation is tilted or the position deviates during the installation process, it cannot be discovered in time, which may lead to the need to dismantle and reinstall during the later inspection, which is a waste of time. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a construction method of an ultra-high exterior wall special-shaped ALC board.

[0005] To achieve the above purpose, the present invention provides the following technical solution: a construction method of an ultra-high exterior wall special-shaped ALC board, the specific construction steps are as follows: Step 1: Intelligent construction preparation: Use BIM technology to simulate the construction site, use VR technology to train construction personnel, determine the best construction sequence and path, and use drones for on-site surveys; Step 2: Modular design and prefabrication: According to the design drawings, the super-high exterior wall special-shaped modeling is modularized and split. Each module is composed of several ALC boards. The ALC boards are prefabricated using a 3D printer or CNC cutting machine. Step 3: Marking of prefabricated ALC panels: According to the preparation of the modeling simulation construction, the prefabricated ALC panels for the simulated construction are also modularized and divided, and a digital label is set on each prefabricated ALC panel in the simulation. Then, the prefabricated ALC panels in reality are labeled with the same digital labels as those on the simulated construction. Each marked ALC panel has the same shape as the ALC panel in the simulated construction. Step 4: Construction and transportation: transport the prefabricated ALC panels with digital logos to the construction site; Step 5: Support structure construction: Use a hydraulic support structure with adjustable height to flexibly adjust the support height and position according to construction requirements. Install smart sensors on the support structure to monitor the support status in real time to ensure safe and stable construction. Step 6. ALC board installation and adjustment: Use modular installation method to hoist the prefabricated ALC board modules one by one to the designated position, and use a manipulator or multiple people to make fine adjustments to ensure that the position and angle of each prefabricated ALC board module are accurate; Step 7. Joint treatment and fixation: Apply special adhesive to the joints of ALC board to ensure the sealing and durability of the joints, and use high-strength bolts or welding to fix the ALC board to the supporting structure to enhance the stability and safety of the structure.

[0006] Step 8. Post-inspection: After the construction is completed, conduct a comprehensive inspection to ensure the installation quality and safety of each module.

[0007] As a further improvement of the technical solution of the present invention, when using VR technology to conduct construction training for construction personnel in step one, it also includes simulating some emergency situations that occur during the construction process through VR for emergency drills and problem-solving training. At the same time, drones are used for on-site surveys, including collecting real-time data such as terrain and weather, to provide accurate basis for construction.

[0008] As a further improvement of the technical solution of the present invention, the modularly split ALC panels in the step 2 are modularly split according to the special-shaped design of the super-high exterior wall, and the shapes and sizes of the ALC panels at different positions are prefabricated in proportion to the shapes and sizes on the actual drawings, so that the size, shape and precision of each ALC panel meet the design requirements of the drawings.

[0009] As a further improvement of the technical solution of the present invention, the ALC board marked in step three is hoisted to the vicinity of the installation height position according to the simulated construction and installation position in accordance with the digital identification of the ALC board of the simulated construction.

[0010] As a further improvement of the technical solution of the present invention, in the process of transporting the prefabricated ALC boards with digital identification to the construction site in step 4, a wooden board with a thickness of not less than 5 mm is placed between each stacked ALC board.

[0011] As a further improvement of the technical solution of the present invention, the intelligent sensor installed in step five includes one or more of a pressure sensor, a displacement sensor, an acceleration sensor and a tilt sensor.

[0012] As a further improvement of the technical solution of the present invention, in step six, during the installation of the ALC board, a 3D scanner mounted on a drone is used to perform real-time monitoring and feedback on the installation accuracy of the ALC board, and the installation error is adjusted in time. During the installation process, it is ensured that no personnel stay or pass under the construction location.

[0013] As a further improvement of the technical solution of the present invention, in step eight, when conducting a comprehensive inspection, the installation of the ALC board is inspected by using a camera mounted on a drone to shoot a video at a high position or take photos at the splicing position.

[0014] Beneficial effects of the present invention: The present invention utilizes BIM technology and VR construction training to optimize the construction sequence and path, reduce duplication and waste in the construction process, and utilizes VR to simulate some emergency situations that occur during the construction process, so as to conduct emergency drills and problem-solving training, and can quickly respond and deal with problems that arise at the construction site. Modular design and prefabrication processing realize the rapid assembly and installation of ALC panels, shorten the construction period, and utilize drone on-site surveys and 3D scanners for real-time monitoring to provide accurate construction data, timely discover and correct installation errors, ensure construction accuracy, and reduce measurement and adjustment time. At the same time, digital identification and modular splitting technology ensure the precise docking of prefabricated ALC panels with the construction site, and use intelligent sensors on the supporting structure to monitor the supporting status in real time, thereby ensuring the stability of the construction process.

[0027] In summary, the present invention designs a construction method for ALC panels of super-high exterior walls with special shapes. First, the construction site is simulated using BIM technology, and construction personnel are trained using VR technology to determine the best construction sequence and path. UAVs are used for on-site surveys. When construction personnel are trained using VR technology, some emergency situations generated during the construction process are simulated by VR for emergency drills and problem-solving training.

The marked ALC panels are installed according to the simulated construction installation position, and are subsequently hoisted to the vicinity of the installation height position according to the digital labels of the ALC panels in the simulated construction. Then, the prefabricated ALC boards with digital labels are transported to the construction site. During the transportation to the construction site, a wooden board with a thickness of not less than 5 mm is placed between each stacked ALC board; Then, a hydraulic support structure with adjustable height is used at the construction site to flexibly adjust the support height and position according to construction requirements. Intelligent sensors, including one or more of pressure sensors, displacement sensors, acceleration sensors and tilt sensors, are installed on the support structure to monitor the support status in real time to ensure safe and stable construction.
