Ano ang mga karaniwang paraan ng reinforcement para sa mesh frame steel structures?
What are the common reinforcement methods for mesh frame steel structures?
Casing Reinforcement of Mesh Frame Steel structure building
The larger steel pipe is ferrule outside the bar, fixed by clips and bolts compression, and the load carrying capacity is increased by the synergistic force of the inner and outer members. The Metal Building casing can be connected by applying adhesive steel glue. For non-bonded fixed connection reinforcement, the calculation, strength calculation only consider the original member of the cross-section, stability calculation consider the role of the new casing, generally only used for compression rod stability insufficient reinforcement.
Steel structure building Advantages: High economy, convenient construction, factory prefabricated. It can inhibit the buckling of rods and improve stability.
Metal Building Disadvantages processing, construction precision requirements are slightly higher.
2. Metal Building Welding for section reinforcement
Welded angles, channels or reinforcing steel pipes are connected to the original bars.
Advantages
Mature process, reliable quality and low cost. Can quickly improve the strength and stability of the section. Disadvantages
Welding heat-affected zone can easily lead to material property degradation or cracks. Fire operation requires shutdown protection, high risk

3. Steel structure building Prestressing reinforcement method
Metal Building Method
Adding prestressing cables and gussets, applying reverse loads to adjust the internal forces.
Steel structure building Advantages
Significantly improves overall stiffness and reduces deformation. No change to the original bars, flexible construction.
Disadvantages: Complex node design, precise control of pre-tensioning required. Long-term monitoring of prestress relaxation.
4.Metal Building Rod Replacement Method
Method
Replacement of higher strength (e.g. Q345 for Q235) or larger cross-section bars.
Advantages
Directly enhance the bearing capacity, the effect is clear.
Metal Building Disadvantages
High construction risk due to the need to set up temporary support.
