Installation Methods for Prefabricated Houses

The installation methods for prefabricated houses vary depending on the type, including the installation of new prefabricated assembled houses, eco-friendly prefabricated container houses, single-story prefabricated modular houses, and the secure connection of floor slabs and beams in fully prefabricated structures, as detailed below:

1. Installation of New Prefabricated Assembled Houses
This type of house is based on standardized components prefabricated in factories. During installation, foundation construction (such as concrete strip foundations or independent foundations) must be completed first to ensure the foundation's flatness and elevation meet design requirements. Subsequently, prefabricated wall panels, floor slabs, stairs, and other components are installed sequentially using lifting equipment, with rigid connections between components achieved through high-strength bolts or welding. During installation, a laser level is used to calibrate verticality, with errors controlled within ±2mm. The roofing system typically employs prefabricated trusses or light steel joists, with waterproof membranes laid and insulation layers fixed after installation.

2. Installation of Eco-Friendly Prefabricated Container Houses
Container houses use modified standard containers as modules. Before installation, the site must be hardened and provided with drainage slopes. Individual containers are fixed to foundation embedments using corner fittings bolts, with adjacent containers connected using flange connections or welded seals to ensure airtightness and watertightness. During interior renovation, light steel joist partitions are installed on the container walls, with electrical conduit holes reserved. The roof can be equipped with photovoltaic panels or green vegetation, but additional structural load-bearing calculations are required.

3. Installation of Single-Story Prefabricated Modular Houses
Modular houses are installed in three-dimensional space modules. During installation, the first-floor module must be positioned and its levelness adjusted, then fixed to the foundation using anchor bolts. When lifting upper-floor modules, guiding devices are used for precise alignment, with high-strength grout filling the gaps between modules to form an integrated load-bearing structure. Window and door openings must be reserved during factory prefabrication, with finished window and door frames directly embedded during on-site installation and sealed with weather-resistant sealant.

4. Secure Connection of Prefabricated Floor Slabs and Beams
In fully prefabricated structures, the connection between floor slabs and beams is a critical node. During installation, shear key slots or embedded steel plates must be reserved on the beam tops, with corresponding recesses or connectors provided on the floor slab ends. By injecting high-strength non-shrink grout into the key slots, the floor slab and beam form an integrated load-bearing system. Additional reinforcement must be provided at the connection points, with double-sided welding or mechanical connections used to ensure reliable reinforcement force transmission.
