Prefabricated buildings have undergone rapid development in China and are now widely used in various regions..

Many regions have mandatory requirements. For example, in my province, it is currently mandatory for all projects to have an assembly rate greater than 50%..

Regarding assembly rate, the calculation rules for assembly rate need to be thoroughly studied. The assembly rate calculation rules vary in each region, so it is important to choose the most suitable assembly rate calculation rule for oneself. There are many doorways inside, and I’ll throw a brick:.

In some regions, the assembly rate is calculated based on area, while for horizontal components and stairs, the assembly rate is calculated based on the horizontal projected area. By increasing the assembly rate by 1%, the volume of prefabricated components for stairs is more than three times that of laminated panels, and the cost of prefabricated components is much higher than that of cast-in-place components..

The tower crane used in general projects does not support directly lifting the entire staircase at the farthest end. A staircase often needs to be installed in two pieces, but whether it is transverse or longitudinal, their joint positions cannot be handled. Yes, it cannot be processed. It can be clearly seen from the appearance: pay attention to the height of the ladder steps at the segmented position when cutting horizontally, and look at the splicing at the junction position when cutting vertically..

Even if the prefabricated design is done well, the probability of water leakage at the interface position is extremely high!.

I won’t go into much else, I have prepared a set of matching materials. If you are interested, you can download and learn on your own..

The construction industry continues to suffer from internal competition, and I will contribute a move to help you become the king of competition.
