1. The choice of punching holes on both sides of the beam is the safest because the stress on both sides is the smallest and does not have a load-bearing effect. If you choose to hit the middle of the beam, it will actually damage the load-bearing effect of the beam.
2. The traditional concept holds that load-bearing beams cannot be perforated, but in fact, they are not. The drilling of load-bearing beams only requires selecting the appropriate position, taking necessary safety measures, and selecting the appropriate position accurately. Generally, decoration masters will focus on the specific location and develop a reasonable drilling plan in the early stage.
3. Punching holes on the beam poses certain risks, so temporary reinforcement should be considered first, such as adding temporary support objects below the beam.
To ensure that the quality does not continue to develop and cause other losses, the original design unit or a design unit with corresponding qualifications are entrusted to carry out structural reinforcement design, and design documents with the signatures of structural engineers and design institutes are produced.
4. The drilling on the beam not only requires selecting the appropriate position, but also the appropriate size. If the drilling diameter is greater than 100, drilling is generally not allowed and has potential safety hazards. If drilling is necessary, the location of the drilling needs to be approved by the property design institute before execution.
