Reinforcement Process for Prefabricated Cement Houses

The reinforcement process for prefabricated cement houses involves combining key components such as floor and roof systems, protruding parts, walls, and foundations, and implementing targeted measures to enhance structural safety. The specific processes are as follows:

Floor and Roof Reinforcement

For floor reinforcement, a reinforced concrete layer can be added above the existing prefabricated slabs, connecting the old and new structures through dowel bar technology to form an integrated load-bearing system. For example, laying a steel mesh and pouring fine aggregate concrete can increase floor stiffness and prevent cracking. Roof reinforcement requires adding reinforcement while installing thermal insulation and waterproofing layers to enhance overall integrity and deformation resistance.

Reinforcement of Protruding Parts and Treatment of Appendages

Balconies, canopies, and other protruding parts require thorough inspection of connection points. If the connection between the balcony and the main structure is insecure, chemical dowel bars or additional connectors can be used for reinforcement. Railings can be reinforced by attaching carbon fiber sheets or adding reinforced concrete coping. Canopies and other components require inspection of support structures, with reinforcement or replacement of problematic supports. Additionally, abandoned signs, external storage cabinets, and other appendages should be removed to reduce the building load and lower safety risks.

Wall Reinforcement

When the load-bearing capacity of brick masonry walls is insufficient, the steel mesh cement mortar overlay method can be used. This involves applying cement mortar and configuring a steel mesh on one or both sides of the wall to enhance load-bearing capacity and seismic performance. Crack treatment should be selected based on width: narrow cracks can be filled with pressure grouting, while wider cracks require the installation of reinforced concrete construction columns on both sides for enhanced restraint. If the connection between vertical and horizontal walls is insecure, additional tie bars or construction columns can be used to strengthen the connection and improve overall building integrity.

Foundation Reinforcement

Foundation reinforcement can involve methods such as increasing size, deepening the foundation, or adding steel mesh to enhance load-bearing capacity, while incorporating reinforcing agents or sealing materials to improve seismic performance. Other reinforcement measures include adding steel beams, columns, or plates to walls and stairs; installing metal frames on exterior walls; incorporating springs or rubber isolators in foundations or structures to reduce earthquake impact; adding reinforcement to key components; adding reinforced concrete adhesive layers to the surface or bottom of prefabricated floor slabs; and attaching carbon fiber sheets or steel plates to enhance floor load-bearing capacity.
