There are many steel structure roof renovation projects for steel structure buildings, such as changing the slope from flat to slope, adding billboards, erecting solar photovoltaics, adding water storage brackets, equipment platform steel frames, etc. If the steel structure roof renovation is unreasonable, it will cause safety hazards. The recent steel structure stadium roof collapse accident is a good example. So what should you pay attention to if you want to carry out roof renovation?
Safety assessment: Before carrying out renovation, a structural safety assessment must first be carried out. Ensure that the structure meets the renovation standards, including structural safety, stability, stiffness, load-bearing capacity, etc. Ensure that the strength of the steel frame, roof trusses, purlins, etc. meet the design requirements and that the roof slope meets the renovation standards. If the stiffness of the components is insufficient or the load-bearing capacity is insufficient, the modification may easily cause the components to deform or even collapse, causing safety accidents. So safety assessment is the most important step.
Select appropriate materials: Roofing renovation requires selecting appropriate materials that meet design specifications and building requirements. Like adding solar panels or other supports, you need to choose the appropriate connection method. For example, if the components meet the stiffness and design requirements, if the roof panel has a large stiffness, you can choose the photovoltaic bracket connector to connect to the roof panel and fix it as close to the purlin as possible. If the stiffness of the roof panel is small, consider using connectors and purlins to connect through the roof panel. Proper connections not only spread the load, but also increase safety and are more cost-effective.
Ensure legal compliance: Consult local policies and building regulations before roofing renovations. Make sure the modifications are permitted and comply with legal requirements. Avoid unnecessary losses caused by failure to meet regulations after modification. Before renovation, you must communicate with the original builder to ensure that the renovation design will not endanger the safety of the original building. Do not make renovations without permission.
Establish construction standards: ensure construction safety and take necessary safety measures to ensure the safety of construction personnel and the site. Try to choose environmentally friendly construction methods and environmentally friendly materials to reduce the impact of construction on the environment. Establish an effective and reasonable quality control system, with specialized quality inspection and supervision personnel to ensure that the quality of the renovation project meets the expected standards.
Find a professional team: Roofing renovation is also a technical job, and you cannot just find a few workers to complete the job. It is necessary to contact a professional construction team for evaluation and construction to ensure the safety of steel structure buildings. If it’s not just roof renovation, adding mezzanines, etc. requires a professional construction team. It is best to contact the original designer and architect for an assessment and ensure safety review before arranging construction.
Precautions for demolition and modification of the original building: Avoid dismantling diagonal supports. Diagonal supports can maintain the stability of the steel structure. The design of diagonal supports is to support and increase the stability of the building. If they are demolished, it will definitely have an impact on the building. Avoid cutting the steel structure or making holes in it. Cutting the steel structure or making holes can easily cause component deformation and undermine the safety of the overall building. Even if a hole is made, reasonable reinforcement should be carried out around the hole. Avoid welding other components on the existing steel structure and avoid rough construction. These behaviors will affect the stability of the building and are particularly likely to cause deformation of components and endanger the safety of the building.
Try to avoid large-scale demolition and modification: try not to move the original building as much as possible.
If the above aspects are taken into consideration before the steel structure roof is renovated, there will basically be no problems. Construction safety cannot be underestimated. Only by treating any construction project or renovation project correctly can we ensure the safety of the project and enjoy the convenience brought by the renovation.
