Prefabricated House Roof Renovation

Prefabricated house roof renovation can be approached from several aspects, including floor and roof reinforcement, reinforcement of protruding parts of the building, wall reinforcement, and waterproofing renovation.

Floor and Roof Reinforcement

If the prefabricated panels are pulled apart or damaged, they can be refilled with cement mortar and reinforced with thicker steel bars to enhance their structural strength. When the roof shifts, iron pipes can be used to support it or brick piers can be added to stabilize its position. For brick-wood structures, "clinch nails" can be used to strengthen the connection between the wooden roof trusses and purlins, and pads can be used to strengthen the connection between the gable walls and purlins. Additionally, diagonal braces can be added between wooden columns to improve overall stability. If the roof is tilted, it needs to be straightened; for decayed or split wooden roof trusses, additional auxiliary beams and columns should be added to ensure structural safety.

Reinforcement of Protruding Parts of the Building

Protruding parts of buildings, such as chimneys, parapet walls, high door faces, water tank rooms on the roof, and staircases, require appropriate reinforcement measures during renovation. For example, vertical tie bars can be installed to enhance the connection between these protruding parts and the main structure through tension, improving their wind and earthquake resistance. At the same time, unnecessary attachments should be promptly removed to avoid additional burdens and damage to the roof under external forces.

Wall Reinforcement

Common forms of wall damage include cracking and leaning. For wall cracking, the method of removing and re-laying bricks can be adopted to remove the cracked bricks and re-lay them to ensure the integrity of the wall. Steel bar reinforcement involves embedding steel bars in the wall to enhance its overall integrity and tensile strength. Methods such as setting up "wall cables," attaching walls for reinforcement, adding attached columns, and buttressing piers can be flexibly adopted based on the specific conditions of the wall. These methods can effectively improve the stability of the wall and prevent further damage.

Waterproofing Renovation

Prefabricated panel roofs are prone to issues such as deformation, cracking of panel seams, frequent hidden water leakage, and poor weather resistance of gutters. A comprehensive roof clearance can be carried out to remove debris and obstacles on the roof, providing a good foundation for subsequent construction. Fine repair of基层 (sub-base) diseases should be conducted to address issues such as cracks and hollowing in the sub-base. Rigid filling and reinforcement of panel seams can be adopted to enhance their sealing and strength. The use of national standard thickened waterproofing membranes for comprehensive protection can improve the waterproofing performance of the roof. For gutters, a specialized exposed waterproofing and systematic renovation plan should be adopted, abandoning traditional patchwork and surface glue application methods. Throughout the process, high-quality waterproofing materials from Oriental Yuhong that meet national standards should be used, with standardized and meticulous implementation of each step.
