【鉄筋NG施工】知らないと危険なミス総まとめ｜定着長さ・継手位置・D13/D16

🔻Do you truly understand "anchoring" and "jointing" in rebar construction? For site supervisors and engineers struggling with issues like "things not going according to the drawings" and "uncertainty about how to make decisions on-site," this video provides a thorough explanation of the technical intricacies of "rebar anchoring and jointing," which hold the key to structural integrity. From basic mistakes like confusing D13 and D16, to the truth about reduced bond strength due to bleeding, and even the consultation process with designers in situations requiring on-site judgment, this video delves deep from the perspective of a first-class construction management engineer. Gain the pride and skills of a professional who upholds structural safety through this video. ---------- 💡What you will learn from this video ・Why is it necessary to have a long anchorage for the top reinforcement (the mechanism of bleeding) ・The basis for the "special anchorage length" required by JASS 5 and standard specifications ・The secrets to "joint location" and "joint concentration ratio" that do not create structural weaknesses ・"Technical solutions" and "how to proceed with discussions" when things don't go according to the drawings on site ------------------------------- ✅ Recommended for: ・Site supervisors who don't want to be ordered to "redo" during reinforcement inspections ・Engineers who want to deeply understand the intent of structural design and reflect it on site ・Professionals who pursue the long-term safety and durability of buildings ・Those who want to strengthen their preparation for the written portion of the First-Class Construction Management Engineer Examination and their practical knowledge ---------- 🎥 About the video Drawings are merely the "designer's intent." The true value of us construction management engineers lies in realizing that intent on site and, at times, proposing the most optimal modifications. This video aims to improve your on-site skills by explaining the essence of rebar construction from both theoretical and practical perspectives. ---------- 📌 [Chapters (Table of Contents)] 00:00 Opening: That rebar is installed incorrectly 00:17 More than just the mistake of D13 and D16, the techniques beyond that 00:47 Chapter 1: Anchorage Length - The depths of the "Don't Pull Out" technique 01:00 Why is the anchorage of the top reinforcement long?
