The development of an attic steel structure construction plan is crucial. Establishing a plan prior to construction not only effectively enhances work efficiency but also allows for better handling of unforeseen situations that may arise, ensuring the quality of the construction.
1. For channel or I-beam construction, generally speaking, channels are sufficient. However, using I-beams offers higher bending strength, though at a higher cost. Moreover, I-beams occupy more space in terms of floor height. The advantage of channel construction is its speed; it's ready for use immediately without any waiting time.
The drawback is that the mezzanine constructed with channel steel produces a slight creaking sound when people walk on it, with the noise being louder as the channel steel size decreases. The use of channel steel is recommended for this construction method.
2. Cast-in-place reinforced concrete. The method of reinforced concrete is a civil engineering technique, but it comes with a condition: the original walls must have steel plate interfaces or other anchoring fixtures connected to the structural steel. Otherwise, the weight of the reinforced concrete cannot be held by ordinary supports or fasteners, and could pose a safety risk.
The advantages of reinforced concrete slabs are that they generally don't sway or make noise when people walk on them (unless the slab is very thin). The drawback is that concrete slabs typically take a long time to complete, with a mere maintenance period of over a month after pouring, not including the preceding construction time, which totals about two months.
If you meet the above construction requirements, experience advises that you have the original construction contractor carry out the work, not a renovation company for this project. Remember this!
3. The construction method for joist gable lofts is rarely used due to the infrequent use of concrete casting, so the focus is on explaining the joist assembly method. If concrete slabs are used, it is recommended to refer to relevant construction books.
