House Prefabricated Beam Construction Video
Here is some information about videos related to the construction of house prefabricated beams:
Animation of a Certain Prefabricated Beam Construction: This video provides a detailed demonstration of the entire construction process of a prefabricated beam. First, a control line with a length of 10 millimeters for the placement of the prefabricated beam is marked on the prefabricated column to ensure construction accuracy. Then, the support frame is installed, with a 20-millimeter-thick wooden pad placed under the support. The bottom and top of the frame use adjustable bases. The frame is made of steel pipes with a diameter of 48 millimeters, connected with couplers. The main wales are also steel pipes with a diameter of 48 millimeters, and the secondary wales are square timbers measuring 50*100 millimeters, providing stable support for the prefabricated beam. Subsequently, the prefabricated beam is lifted using a lifting beam spreader, with the hooks attached to the lifting points of the prefabricated beam. After the prefabricated beam is placed steadily, the hooks are detached. Finally, the elevation of the prefabricated beam is re-measured, with the allowable elevation error controlled within 5 millimeters to ensure construction quality.
Video: 'Learn Engineering Through Animation 06: T-Beam Prefabrication Construction': The theme of this video is T-beam prefabrication construction, but the video content is not described in detail. However, from the title, it can be inferred that the video may vividly demonstrate various aspects of T-beam prefabrication construction through animation, including formwork installation, rebar tying, and concrete pouring, helping viewers quickly understand the basic process and key points of T-beam prefabrication construction.
Video: 'Full Process of Precast Box Girder Pouring, On-Site Construction Footage': This video mainly showcases the pouring process of a precast box girder. It is mentioned in the video that the concrete strength is C50, and one girder requires 42 cubic meters of concrete. During pouring, the bottom slab of the box girder is poured first, and the concrete for the bottom slab flows through the web. It is emphasized that the concrete should have good 'fluidity' and 'cohesiveness' to ensure that it can fully fill the formwork, avoiding quality issues such as voids and pitting, and ensuring the strength and durability of the precast box girder.
Video: 'Building a Villa Roof Backwards: Prefabricated Beams Plus Hollow Bricks, Fast Forming and Resistant to Cracking': The theme of this video is the construction method of using prefabricated beams plus hollow bricks for villa roofs. This construction method has advantages such as fast forming and resistance to cracking, improving construction efficiency and ensuring roof quality. The video may showcase the production and installation of prefabricated beams, as well as the laying of hollow bricks, providing a new idea and method for villa roof construction.
