Proportion of Prefabricated Panels for Houses

The proportion of prefabricated panels for houses varies depending on factors such as material and specifications. The proportion of ordinary concrete prefabricated panels typically ranges from 2.4 to 2.5 tons per cubic meter. Here is a detailed explanation:

Ordinary Concrete Prefabricated Panels: Ordinary concrete prefabricated panels are a relatively common type, with their proportion usually falling within the range of 2.4 to 2.5 tons per cubic meter. This proportion data is derived from the material properties of ordinary concrete, which is mainly composed of cement, sand, and gravel mixed in certain proportions. There may be slight differences in the quality and proportioning of materials from different batches, but overall, the proportion remains relatively stable within this range.

Prefabricated Hollow Panels: The weight representation of common prefabricated hollow panels (such as the GB series) differs from that of ordinary concrete prefabricated panels. They are usually measured by weight per square meter, approximately ranging from 80 kg to 120 kg. To convert this to linear meter weight, taking a prefabricated panel with a standard width of 1.2 meters as an example, its weight per meter may be around 96 kg to 144 kg. Prefabricated hollow panels have a hollow structure inside, which reduces the panel's own weight while ensuring a certain level of strength, making their application in construction more flexible, especially suitable for building parts with weight requirements.

Prefabricated Concrete Floor Panels Commonly Used in Old Buildings: The prefabricated concrete floor panels commonly used in old buildings have specific specifications, with common dimensions being 4 meters in length, 0.6 meters in width, and 0.12 meters in thickness. According to the conversion relationship between volume and proportion, a single panel weighs approximately 600 - 700 kg. These floor panels were widely used in old buildings in the past, and their specifications and weights were determined based on the building requirements and construction conditions at that time, capable of meeting the load-bearing requirements of buildings during a certain period.

In actual building applications, when selecting prefabricated panels, it is necessary to comprehensively consider various factors such as the building's design requirements, load-bearing capacity, and construction conditions to determine the appropriate type and specification of prefabricated panels.
