Jak powstają prefabrykaty budowlane? - Fabryki w Polsce

Precast concrete elements are components used for assembly on the construction site. It's hard to imagine any construction project without them. They are used in the construction of both large structures, such as sports stadiums, and smaller ones, such as single-family homes or small architectural elements. They are eagerly used by investors due to their undeniable advantages. To see how precast concrete elements are made, we visited Betard, a company that has specialized in their production for 25 years. Work on precast elements begins in the design department. This is a crucial stage of production. The final result of the entire construction depends largely on the designs created here. The designs are then passed on to subsequent departments within the company. In the reinforcement shop, the supporting framework of the precast element is created – the reinforcement, made of steel bars. This reinforcement strengthens the precast element and protects the concrete from tensile forces. Based on the design, the bars are cut to the appropriate length and then bent. Once they have the desired shape, they are bonded together, thus forming the frame. At the same time, the mold is being prepared in the carpentry shop, which will be poured with concrete during production. The mold is made of plywood. Sealants are installed at the joints to prevent the concrete from leaking out of the mold after pouring. Creating the mold requires extreme precision; all dimensions must be maintained so that the shape of the precast element matches the design. Once all the elements are ready, it's time to visit the precast production hall. First, the reinforcement is placed in the precast element mold. The mold has been previously greased to prevent the concrete from sticking to the walls when demolding. At the same time, the most important component of the entire production process is being prepared in the concrete batching plant. The finished concrete is placed in the mold. Simultaneously, it is subjected to vibration. This allows the mix to deaerate and thus compact. The concrete in the poured mold will now cure. This requires special conditions. As concrete cures, it develops its properties. We can see a filigree ceiling leaving the curing room. After demoulding, it will be ready for use on the construction site. The variety of products manufactured at the Betard plant is enormous. From paving stones to enormous, over 20-meter-tall columns used in the construction of production halls. Therefore, they have already been used in several thousand construction projects across Poland. -- Website: https://fabrykiwpolsce.pl Subscribe to the channel: http://bit.ly/2trnVPE Facebook: http://bit.ly/2ur7xLQ "Factories in Poland" is a journey through production plants located throughout Poland. It's safe to say, we're exploring the Polish industry. We were inspired by the popular program "How It's Made?", known from the Discovery Channel. Every week, we visit a production plant with our viewers to see how a selected production process is carried out. Each week, a documentary film appears on our channel, showing how products such as concrete are produced. Machines, cable slings, yachts, wires, windows, railway switches, radiators, Styrofoam, and more. You're probably also interested in how food is made? On our channel, we've shown things like sausages, Pepsi, Prince Polo, breadsticks, mustards, ketchup, mayonnaise, cheese, and much more. It's amazing how fascinating production can be. Science and technology offer so much interesting information. Every week, you'll discover the hidden secrets of factories with us. A factory holds no secrets for us. And if you'd like to learn how things work, how a particular machine works, how an amusement park operates, or how to brew beer with a popular brewery, follow Fabryki w Polsce Extra. Our new format, which we publish periodically on the channel. Discover new factories with us, abundant throughout Poland.
