For example, if the connectivity is not strong, the seismic resistance and stability of the building itself will be reduced.

At present, China’s precast buildings are not mature and less used in buildings; second, the labor cost is not low.

Therefore, it is necessary to prevent the corresponding problems to a certain extent before design and construction.

Now the development trend of the construction industry is more economical, more integrated and more assembled.

If the accuracy requirements of structural construction can not meet the corresponding standards, the construction of precast buildings will face great obstacles and bring some losses.

Generally speaking, it is the secondary design of the whole building.

In plane design, the assembly status of building components should be taken into account, the requirements of relevant size and suite modules should be analyzed, appropriate building internal structure should be selected, and the load-bearing wall and pipe well should be placed in a reasonable area to ensure the reasonable division of performance area of the internal structure of the building, Ensure the beauty of the building.

The joints are designed accordingly from the perspective of anti freezing and anti-seismic 2 – related problems in the design of cast structure ▌ 1 Problems existing in design and construction in the specific design and construction process, there will still be various practical problems, which will bring certain harm to the later construction quality, and sometimes even bring large economic losses.

After the corresponding construction drawings are designed, the next step is to design the parts of each part of the cast building.

▌2.

Design and construction drawings in the early stage of precast building construction, the most important work is to design the whole building.

With the vigorous development of the construction industry, people pay more attention to environmental protection and energy conservation.

In addition to the corresponding communication with the processing party, there are many factors to be considered by the design department and relevant designers.

The corresponding design scheme and drawings given by the design department are the most important basis for construction in the later stage.

With the rapid development of science and technology, the technologies used in the construction industry are constantly bringing forth the new.

The corresponding structure should be built in the design process and can match the later construction conditions.

But in fact, the importance of parts design is no less than that of the overall design of the building, because for precast buildings, parts are the foundation and soul of later construction.

If there is a problem with the quality of the connection part, the building itself will bring certain potential safety hazards to the owner in the later stage.

They should not only understand the standard construction and disassembly of facilities, but also understand the structure of specific nodes, which makes the labor cost of designers and construction personnel not low.

▌2.

When designing the node, we should not only consider the relevant physical factors, but also consider the climatic conditions, geological conditions and other factors of the construction site.

In order to reduce the adverse impact of construction on the environment, precast buildings do not have much construction waste, and can be freely matched and installed quickly 1 – Analysis on key points of precast building design ▌ 1 Key points of plane and facade design the design of precast buildings starts with plane and facade design.

After the completion of production, many parts are faced with a transportation guarantee problem in the process of transportation from the production partner to the construction site or to the warehouse.

In the process of construction, the stability of connecting structural joints is very high, because it directly affects the quality of the building itself.

The development speed of precast buildings is very fast, and the promotion scope is more and more broad.

Compared with ordinary building construction, the most important aspect of designing structural member node precast building is the connection between various structural members, which is the node of structural members.

For example, preliminary preparations, use of corresponding raw materials, use of funds, conditions of the construction site, equipment level, etc.

In addition, because the precast building is still one of the construction industry, the corresponding design drawings also include more parts, such as the overall fire protection design and sound insulation design of the building.

Compared with previous buildings, precast buildings are more important for design Teachers and construction personnel have high requirements.

At present, the scale of building construction is becoming larger and larger, and the requirements for accuracy are becoming higher and higher.

▌4.

Precast buildings just have these characteristics.

Nowadays, few architectural courses in Colleges and universities in China involve precast architecture.

Moreover, the connection between various parts of precast buildings is often more complex, and the requirements for design drawings are higher.

During the design, the corresponding design departments and relevant designers need to contact the processing partners, so as to ensure that the structure is built in the later production process, meet the corresponding standards, and lay a more solid foundation for the later construction.

Due to the previous model of the construction industry, there is a large talent gap in precast architecture, as follows.

Problems in the process of development (1) Higher economic cost today, China’s precast buildings are small in scale and have not formed industrialization, so compared with previous buildings, the cost is not low.

First, the cost of building raw materials is not low.

There is a large gap in design talents.

There are no problems in the production and later use of various parts, which makes the investment cost higher, but the quality of the final building is not high, which reduces the overall economic benefits of the building itself.

This makes the corresponding structure suffer certain damage during transportation and can not meet the requirements of later construction.

Even if some schools open precast architecture courses, they are only a brief description, and almost do not include the problems encountered in design and construction Course learning scope; There is a big talent gap in construction..

First of all, there are often some gaps or other quality problems in the connection between various parts of precast buildings, which has a great impact on the quality of the building itself.

(2) There is a shortage of professional and technical personnel.
