Prefabricated Balcony for Prefab Houses

The prefabricated balcony for prefab houses is constructed using factory-prefabricated and on-site assembly methods, featuring modularity, standardization, and high efficiency. It is suitable for high-rise buildings and projects with high quality requirements.

1. Construction Methods and Characteristics

The BIM-based construction method is the core technology for prefabricated balconies, with characteristics including:

1. Modular and Modular Design: Balcony components are produced in factories using standardized molds, ensuring precise dimensions for quick on-site assembly.
2. 3D Visualization and One-Time Forming: BIM models are used for construction simulation, ensuring that components and ancillary facilities (such as pipelines and railings) are processed in the factory in one go, reducing secondary on-site operations.
3. Adjustable Support Devices: An adjustable component stable support system is adopted to meet the installation needs of different building structures, ensuring construction safety.
4. Factory Production: Components are produced in enclosed workshops, minimizing environmental impact and ensuring high quality control.

2. Construction Process

The installation of prefabricated balconies must strictly follow the following steps:

1. Base Treatment: Clean debris from the installation surface to ensure a flat structural surface.
2. Line Marking and Positioning: Mark the installation control lines for the balcony slab and air conditioning slab according to the design drawings.
3. Support Installation and Tying: Install temporary support frames and reliably tie them to the inner side of the structure to prevent overturning.
4. Elevation Adjustment: Precisely control the bottom elevation of the balcony slab using adjustable devices.
5. Lifting and Verification: Use lifting equipment to lift components and verify whether the position and elevation errors comply with specifications.
6. Rebar Tying and Concrete Pouring: Tightly tie the balcony rebar to the main structure rebar and pour beam-slab concrete to form an integral connection.
7. Support Removal: Remove the temporary support system after the concrete reaches the design strength.

3. Component Customization and Advantages

Prefabricated balcony components can be customized according to project requirements. Taking the products of Shandong Mingjiu Prefabricated Construction Technology Co., Ltd. as an example:

• Materials and Performance: Made of reinforced concrete, they offer high waterproofing precision, superior seismic performance, and a long building lifespan.
• Production Efficiency: The factory produces and sells its own products, with installation completed in 1-2 hours and a delivery cycle of 4-5 days, supporting logistics distribution.
• Cost and Environmental Protection: Priced from 2400 yuan per cubic meter, they reduce on-site material waste, comply with green building standards, and are suitable for both home decoration and industrial decoration scenarios.

4. Building Type Adaptability

Prefabricated balconies are mainly used in prefabricated concrete buildings, especially partially prefabricated structures. These buildings combine prefabricated components with cast-in-place concrete, balancing construction speed with structural integrity, and are particularly suitable for winter construction or projects with tight schedules.
