by The current construction method still relies mainly on on-site pouring, and the technological content and production efficiency of the entire industry are very low, far inferior to manufacturing. Is it possible for the construction industry to achieve a leap from “manual” labor to advanced “assembly line” production in 100 years, and is it possible to achieve a leap from “whole” furniture to “assembled furniture” in 50 years? This is the dream of generations of builders, and after the concept of “prefabricated building” was proposed, this dream has shown us new hope in the traditional industry. So, what is prefabricated building? How are prefabricated buildings produced? How was the construction done on site? Today, the editor will take you all to learn more..
Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories, where building components and accessories are processed and manufactured, such as floor slabs, wall panels, stairs, balconies, etc. After the prefabrication of building components and accessories is completed, they are transported to the construction site for assembly. We can imagine pre made components such as beams, slabs, columns, and walls as blocks. At the construction site, we only need to assemble them together, just like building blocks. This kind of “industrialized” and “industrialized” architecture has been widely used in Europe, America, and Japan..
Prefabricated components are prefabricated in factories, which can maximize the improvement of common quality problems such as wall cracking and leakage, and enhance the overall safety level, fire resistance, and durability of residential buildings..
Efficiency is the reward, and prefabricated buildings progress about 30% faster than traditional methods..
Hyaluronic acid in the construction industry can make building products long-lasting and youthful. After the industrialization of indoor decoration, it is possible to receive express delivery at home, which can be dismantled and installed quickly and effectively..
Improve the speed of real estate listings, alleviate the current situation of insufficient market supply, and no longer have to queue up all night to buy a house. After the popularization of the industry, construction costs can be reduced and housing prices can be effectively suppressed..
Traditional job sites have a large number of workers, but now a large number of construction site operations are moved to factories, and only a small number of workers need to be left on site, greatly reducing the incidence of on-site safety accidents..
The original on-site pouring operation is extremely rare, and the health does not disturb the people, bidding farewell to the “gray and hazy”. In addition, the reuse rate of steel templates and other materials has been improved, and waste, loss, and energy savings can be reduced by more than half..
Next, we will introduce how assembly is produced. Taking prefabricated building panels as an example, the production process is: steel formwork production → steel reinforcement binding → concrete pouring → demolding..
Production line operation. After demolding, the finished prefabricated board and prefabricated components are completed and temporarily classified and stacked in the factory, ready to be transported to the construction site..
After demolding, the prefabricated components are completed, and the finished products are temporarily classified and stacked in the factory, waiting to be transported to the construction site..
At this stage, the prefabricated components are produced, and the next step is to transport these components to the site for hoisting construction. So what is the construction process of prefabricated hoisting? Let’s take a look together..
Taking prefabricated frame structures as an example. After the construction of the first floor is completed, the upper column is lifted first, followed by the main beam, secondary beam, and floor slab. After the hoisting of prefabricated components is completed, the steel bars at the connecting parts are tied, and finally the pouring of nodes and cast-in-place layers of beams and slabs is carried out. The following is a specific construction process diagram:.
