House Prefabricated Beam Installation Video

Here are some introductions to videos related to the installation of house prefabricated beams, which can help understand the installation process:

Animation of the Construction of a Certain Prefabricated Beam: This video, produced by Wang Zhenfei, provides a detailed demonstration of the construction process of a prefabricated beam. First, a 10-millimeter control line for the length of the prefabricated beam's placement is marked on the prefabricated column to provide precise positioning for subsequent installation. Next, the support frame for the composite floor slab is constructed. The supports are cushioned with 20-millimeter-thick wooden pads, and adjustable bases are used at the bottom and top. The frame is constructed using 48-millimeter-diameter steel pipes connected with couplings. The main beams also use 48-millimeter-diameter steel pipes, while the secondary beams use 50*100-millimeter square timbers to ensure the stability of the support system. During the lifting of the prefabricated beam, a lifting beam spreader is used to accurately hang the hooks onto the lifting points of the prefabricated beam. After the prefabricated beam is placed steadily, the hooks are detached. Subsequently, the elevation of the prefabricated beam is re-measured, with the allowable error strictly controlled within 5 millimeters to ensure installation accuracy. Finally, other prefabricated beams are installed in sequence, and their elevations are re-measured to complete the entire installation process.

Full Process of Installing a 35-Meter Prefabricated Beam, Revealing Details of Continuous Beam Construction: This video shows the completion status of the installation of a 35-meter-span prefabricated beam, focusing on the construction details of converting a simply supported beam to a continuous beam. The construction method of converting a simply supported beam to a continuous beam can fully leverage the load-bearing advantages of the continuous beam, improving the overall structural integrity and load-bearing capacity, and providing important reference value for the installation of large-span prefabricated beams.

Aerial Installation Process of Prefabricated Crossbeams: The video focuses on the aerial installation of prefabricated crossbeams. A crane precisely lifts a prefabricated beam using steel cables and suspends it in the middle position between two foundation piles. At this time, two construction workers climb onto platforms on both sides using ladders and manually guide the reserved holes at the bottom of the beam to ensure accurate positioning of the prefabricated beam. This process requires high operational precision and collaborative coordination from the construction workers and is a key step in the installation of prefabricated beams.
