00:00 – The video begins with the execution of a Unilite beam roof. 05:30 – The presenter explains key points for purchasing beams. 06:07 – Cutting the beam supports is demonstrated. 06:27 – The first beam is positioned next to the concrete beam. 07:40 – Concrete is poured at the start and end of the beams. The tutorial then covers the components of a beam, including the upper compression reinforcement, shear reinforcement, and tension reinforcement, and discusses how beam supports can be manufactured in a workshop or factory, either as single or double supports. It explains reinforcement detailing, zigzag spacing, and the process of pouring concrete, including the size of the concrete footing, gradation, and height. The video also distinguishes between standard and pre‑tensioned beams, and shows how to use a clay mold for the footing. It then introduces the block beam roof, its thickness, and how to place beams on the roof and connect them to the concrete beam. The presenter discusses load capacity, common issues such as sagging, negative keystone, and jack spacing, and provides solutions. The tutorial covers the installation of ducts, secondary beams, and reinforcement detailing for the roof, including negative moment bars, outboard bars, and thermal bars, as well as the use of a horizontal clamp or joint for roof continuity. It also explains the use of double beams, the difference between double and single beams, and the use of fire‑resistant Unilite for filling. Finally, the video shows the concrete pouring of the beam roof.
