Prefabricated Concrete Building

Prefabricated buildings have the advantages of high level of industrialization, ease of winter construction, reduction of wet work on the construction site, reduction of material consumption, and reduction of construction site dust and construction waste. It is conducive to achieving the purpose of improving building quality, improving production efficiency, reducing costs, achieving energy saving and emission reduction, and protecting the environment.

Prefabricated buildings have been widely used in many countries and regions, such as Europe, Singapore, and the United States, Japan, New Zealand and other countries in high-intensity earthquake zones. In recent years, due to the increasing requirements for energy conservation and emission reduction, as well as the substantial increase in labor prices and other factors, the application of precast concrete components has begun to break away from the trough, showing a rapid upward trend. Kingsun superplasticizer admixture for concrete is widely used in construction.

Design principles of prefabricated concrete buildings

The prefabricated concrete building refers to the concrete structure type house building which mainly adopts the concrete prefabricated components produced by the factory and is designed and constructed by on-site assembly. The assembly method of the components generally includes operations such as post-pouring superimposed layer concrete on site, and post-pouring concrete connection after steel anchoring.

Reinforcing bars can be connected by sleeve grouting, welding, mechanical connection and lap connection with reserved holes. The design of prefabricated concrete buildings should meet the requirements of building function and performance, and meet the design principles of sustainable development and environmental protection. Various reliable connection methods should be used to assemble precast concrete components, and the assembly and integration technology of main structure, decoration and equipment pipelines should be adopted to comprehensively coordinate water supply and drainage, gas, heating, ventilation and air conditioning facilities, lighting and power supply and other equipment. System space design, considering the requirements of safe operation and maintenance management.

Scope of application

In architectural design, there are building types with a high degree of standardization, such as residential buildings, school buildings, kindergartens, hospitals, office buildings, etc. There are also building types with a low degree of standardization, such as theaters, stadiums, and museums. Prefabricated concrete buildings have relatively high requirements for building standardization, so that prefabricated components of the same specifications can be maximized and bring better economic benefits. Therefore, it is advisable to choose a plane layout with a relatively regular body and a large space, and arrange the positions of the bearing walls and tube wells reasonably. In addition, the development of prefabricated building systems should adapt to the requirements of building functions and performance in various parts of our country, and follow standardized design, modular coordination, and factory-based processing of components.

Main points of prefabricated concrete building design

The layout of the main structure of the prefabricated building should be simple and regular, the convex and concave changes of the plane should not be too deep, and the large-space layout should be selected. In order to realize large-scale production in factories, industrial buildings should first ensure the standardization and modularization of product dimensions, so that products can be easily produced on assembly lines. In the pre-planning and conceptual design stage, the production and transportation conditions of the components, the space required for stacking and lifting equipment are directly combined, and on-site installation is considered.
