The next five years will be a stage of rapid development of precast buildings.
Professional precast architectural designers should put the design in front and eliminate the “trilateral” project.
Article 4 of the second major point of the national policy “opinions of the Ministry of housing and urban rural development and other 15 departments on strengthening the green and low-carbon construction of the county” clearly states that “develop new construction methods such as precast steel structure”.
In 2021, under the “14th five year plan”, all localities successively released the next five-year plans for the construction industry, and issued many relevant policies conducive to the cast construction industry, with a total of 30 + local policies.
Vigorously develop precast buildings”.
04 precast architectural design is closely linked.
However, in the traditional construction drawing design, precast architectural design is only a branch of the structural specialty.
Increase the investment in vocational skills training, establish training bases, and strengthen post skills upgrading training…” – the guiding opinions of the general office of the State Council on vigorously developing precast buildings.
At present, precast architectural design As a specialty in traditional construction drawing design, it is also closely related to the reservation and embedding of building facade, function, strong and weak current, HVAC, fire protection and water supply and drainage.
Most of these components are manufactured in the processing yard.
Therefore, while learning assembly design, we need to master these professional basic knowledge in order to grasp the whole picture of assembly design.
these policies indicate that the dress matching architecture will enter a rapid take-off stage in 2022.02 the corresponding demand for talents related to precast architecture will increase significantly.
“Vigorously train professionals in the design, production, construction and management of precast buildings…
In addition, precast concrete design not only has high requirements for structural safety, but also involves all disciplines such as building function, facade, building materials, HVAC, strong and weak electricity, water supply and drainage and fire protection, and is also restricted by production and construction factors.
Beijing’s policy points out that “precast buildings will account for more than 40% of the new construction area in 2022, By 2025, the proportion of precast buildings in new buildings will reach 55% “.
If the project is designed, constructed and modified at the same time, it will cause a huge waste of materials, labor and machinery.
Source of positive design flow chart of precast concrete buildings: xuanrui “PC precast structure design treasure book” 05 precast building design talents need to be all professional talents.
“Opinions on promoting green development of urban and rural construction” also clearly states that “strengthen financial, financial, planning, construction and other policy support…
Due to the change of market demand caused by the change of policy, it has gradually become a relatively independent new major in recent years, which means that the relevant talent reserve is scarce.
Designers should understand the processing and production process, assist manufacturers and construction units in production and installation in the process of processing, production and installation, and ensure the rationality of precast component production and construction and installation.
These precast components will become a very important part of the main structure of the project.
In the design and production of concrete precast components, the components should be separated from the overall structure to form various precast components, such as precast columns, precast shear walls, precast exterior walls, laminated beams, laminated plates, precast stairs, precast balconies, etc.
It is necessary to point out lightning points and pits for students.
In the relevant policies of Hainan Province, it is clearly pointed out that “ensure the full deployment of precast buildings in the province after 2022” and “by the end of 2025, precast buildings will account for more than 80% of new buildings”.
The design of precast concrete building can be understood as that after the overall calculation of the traditional steel structure, the steel structure manufacturer will deepen the design.
Precast buildings are composed of many precast components, including precast columns, precast shear walls, precast exterior walls, laminated beams, laminated plates, precast stairs, precast balconies, etc.
In other words, precast architectural design is an “edge specialty”.
Therefore, in the training of talents, it is also necessary to point out the thunder points and pits in the design of precast buildings to learners.
Although precast architectural design is only one link of precast architecture, its role can not be ignored.
The cultivation of talents in the industry should be advocated in terms of the principle of precast design.
03 talent cultivation in the primary stage of the industry should be adapted to the trend.
However, the production and manufacturing of concrete precast components in China has just entered the primary stage, In more developed countries, the production accuracy is still insufficient, and some fine processes may take a long time to develop.
If the designers do not take these points into account, these errors will pay several times the cost of mistakes in the later implementation project.
The next five years will be a stage of rapid development of precast buildings.
Congratulations on the successful application of Henan sixth construction company for “Henan intelligent construction engineering technology research center”..
After vigorously developing precast buildings, talents with professional knowledge will become hot.
It even plays a key role, which is the link between production and construction.
The design of precast concrete building structure is based on the concept of “equivalent cast-in-place”.
The design process of precast concrete buildings is closely linked.
In order to ensure the construction of precast concrete buildings, it is necessary to comprehensively improve the environmental, social and economic benefits of precast concrete buildings in accordance with the requirements of applicability, economy, safety, green and beauty.
