This invention proposes a construction device and its method for protective opening of existing building walls. The construction device includes a guide rail module, a cutting module, a dust removal and cooling module, and a safety control module. The method of using the device involves positioning and laying out lines, installing the guide rail module, installing the cutting module, connecting the cutting module to the dust removal and cooling module, and installing the safety control module. After installation, the cutting module is adjusted to the top of the guide rail module. After inspection, the dust removal and cooling module and the cutting module are activated and positioned. Then, the cutting module is controlled by the handwheel on the cutting module to cut and move the wall. During the cutting process, the control force of the safety control module is adjusted simultaneously to ensure the safety of the cutting process. The construction device and its method of use, through reasonable mechanical design, enable the equipment to cut walls safely and quickly, while optimizing the wall-building steps and methods, improving efficiency and reducing costs.

This invention relates to the field of building construction technology, specifically to an integrated construction process for prefabricated buildings using aluminum formwork and climbing scaffolding based on BIM technology. The process includes the following steps: S1: Utilizing BIM technology to refine the building information model (BIM). This refinement includes the aluminum formwork, climbing scaffolding, prefabricated components, main structure, and electromechanical piping. Collision detection and design optimization are performed using the BIM model. The connection between the climbing scaffolding and the main structure is then reinforced with bolts. Further refinement is given to the aluminum formwork system for the exterior window sill grooves and bathroom curbs. S2: Pre-construction preparations are carried out, including prefabricated component production, customized aluminum formwork processing, and equipment debugging. Prefabricated component production: Based on BIM model data, prefabricated beams, slabs, and columns are produced in a standardized factory to ensure accuracy. This invention utilizes BIM technology to solve the mismatch between traditional climbing scaffolding and industrialized construction, and addresses the issues of low component assembly accuracy and complex construction organization in prefabricated buildings.
