How Ancient Roofs Were Built Without Nails (Animated Short)

AnimationVideos 3D

Ever wondered how ancient temples and palaces supported their massive, sweeping roofs without a single nail or screw? This stunning 3D animation delves into one of the most ingenious inventions in architectural history: the ancient Chinese dougong (斗拱) bracket system.  Join us as we explore the brilliant evolution of this design. You'll see how ancient engineers solved critical problems step-by-step, starting with a simple wooden post and beam. Watch how each innovation helped protect the structure from rain, support immense weight, and extend the eaves, creating the iconic and beautiful rooflines famous throughout East Asia.  This animated short is a perfect blend of history, engineering, and satisfying visuals. If you love learning about ancient technology and marveling at human ingenuity, this video is for you!  This isn’t just history—it’s a masterclass in sustainable, resilient design that modern architects still study today.  👇 Want more mind-blowing historical tech? ➡️ SMASH that LIKE button if you’re amazed by ancient ingenuity! ➡️ COMMENT below: What’s the most impressive ancient technology you’ve ever learned about? ➡️ SUBSCRIBE & hit the bell for weekly animated deep dives into science, history, and forgotten inventions!  🔔 Turn on notifications so you never miss a video!  #3danimation  #history  #architecturelovers  #engineeringfacts  #ancientchina  #Dougong #Woodworking #AnimatedShort #Educational #HowItsMade #AncientTechnology #ChineseHistory #StructuralEngineering #Joinery #TimberFrame #AncientInventions #HistoryExplained #SatisfyingAnimation #ArchitecturalHistory #MortiseAndTenon #Pagoda #ForbiddenCity #DidYouKnow #WorldHistory #3DVisualization #BlenderAnimation #AncientEngineering #IngeniousDesign #Woodcraft #HistoricalFacts #ViralVideo #LearnSomethingNew #FactShorts #HistoryBuff #Innovation #Construction #EastAsianArchitecture #traditionalarchitecture  #buildingtechniques  #arthistory

00:00If you cross the grass at the top of the pillar and embed two wooden beams that are close to each other,

00:05the beams and columns will lock each other, resulting in a stable frame structure,

00:09which can hold up the roof and get a house.

00:12But the rain will wet the pillar, causing the pillar to rot.

00:15Smart, you can insert a bridge beam and build a cool one on it,

00:18so that the eaves can be farther out to avoid the rain.

00:21But the beam is too glued and easily deformed and damaged,

00:24so the cow sets an inclined beam support under the beam to drag it.

00:28In order to get a tighter open shoulder, you increase the column firmly,

00:32but this will cause the beam to become longer and easily damaged.

00:35In the same way, you can also use the inclined beam support to drag it,

00:40but the inclined beam support makes the space that is not high very difficult to use.

00:45Clever, you can think of the doom to continue downward grooving,

00:49design the good name into a trapezoidal cross,

00:51and then set up beams on it, so that with greater support, you can achieve a longer span structure.

00:56But most of the wood is dug out at the top of the column, which is not strong enough.

01:01You can set the damage head on it,

01:02and the larger wood top is grooved and fixed on the column, so as to invent the bucket.

01:07The beam is designed into a bow shape to be embedded in the bucket.

01:10You invented the arch, and the bow arch is combined layer by layer,

01:14so that the measurement can be lifted up.

01:16Then congratulations, you invented the head arch.
