State Construction Training – Assembled+Decoration=”More, faster, better and cheaper”?
What is assembly decoration? Assembled decoration is a kind of decoration method that combines indoor decoration components and products into finished residential buildings mainly in the form of physical connection.
The amount of materials used in the first decoration of traditional decoration is relatively large, and the second reconstruction causes more material waste.
Specifically: First, there are many common problems in decoration quality.
The decoration quality is easier to be guaranteed, “good and economical”.
Assembled decoration is not completely equivalent to industrial decoration, it is just a technical means of interior decoration industrialization.
At the same time, because the life cycle of interior decoration is different from that of building structure, the former is 5-10 years, and the latter is 50 years, so the interior decoration must face secondary transformation.
Compared with the traditional method, the precast decoration is “heavy factory, light site”.
However, due to the combination of traditional decoration and the main structure, it is inevitable to smash and chisel during the transformation, resulting in a large amount of construction waste and environmental pollution.
The heavy reliance on manual work has become an important factor in the low entry threshold and poor industrial competition pattern of the traditional decoration industry.
According to the experience data of Beijing Guarantee Housing Center, the construction period for a 50 square meter public rental house to be decorated by assembly is only 6 days, while the traditional decoration period is 30 days, which significantly improves the construction efficiency..
Because traditional decoration will partially damage the protective layer of the main structure and chisel the wall, it is more likely to cause structural safety problems.
From the aspect of construction, as the precast decoration is divided into factory component production and on-site installation, the factory component production does not affect the project progress, while the on-site installation requires all dry construction without secondary processing, so the construction period is significantly shortened compared with the traditional way.
Enterprises with technology accumulation in BIM will be able to better reflect their competitive advantages in the competition of the assembled decoration industry.
Do you know the four disadvantages of traditional decoration? Traditional decoration has been popular in China for a long time.
The difficulty in on-site management has become a major obstacle for most decoration companies with limited management radius and difficult scale to break through.
Fourth, material resources are seriously wasted.
The decoration accuracy has been greatly improved to the millimeter level, and the impact of human factors has been greatly reduced.
Second, there are many hidden dangers in the decoration process.
There are many on-site links, many types of work, heavy reliance on manual work, long time consuming, difficult quality assurance and other problems.
According to the research in the Design and Construction of Assembled Decoration, the annual loss caused by the second decoration is more than 30 billion yuan.
According to relevant research results, the number of deaths caused by indoor pollution in China each year reaches 111000, and 42.1% of the total number of newly added children with congenital disabilities is related to indoor air pollution.
From the perspective of products, the industrial thinking design concept of assembly decoration divides eight major decoration modules into a variety of parts, and the decoration company provides several options for each part, thus forming the personalization in standardization and “multiple” product choices.
Building information model (BIM) is an important auxiliary tool for integrated architectural design.
The application scope of cast decoration is increasingly broad, and it is gradually developing from local application to whole system application.
Parts are manufactured in the factory and only installed on site.
All the construction work of traditional decoration is completed on site, while the precast decoration divides the original construction work into two parts: factory component production+on-site installation.
The common problems such as moldy walls, damp and powdery walls, peeling off of the top of walls in traditional houses are all caused by the difficulty in controlling the quality of traditional wet work; Uneven ground, water and electricity pipe rupture and other problems are caused by poor construction accuracy.
Advance in the design stage will significantly improve the design capability of building structure and decoration integration.
Whether new construction or reconstruction of existing buildings, residential buildings or public buildings, concrete buildings or steel structures, precast decoration is gradually accepted because of its incomparable advantages over traditional decoration.
The design can be completed by employing a better team, and the cost can be shared by all users who choose this system.
Compared with the traditional decoration design, the precast decoration design is more cost-effective.
Compared with traditional wet work, precast decoration has significant advantages in field work, mainly in the following aspects: fast installation.
Compared with traditional decoration, it has the characteristics of “more, faster, better and less”, and its advantages are very obvious.
Many on-site construction processes and complex processes lead to many process hazards.
From the perspective of the project operation process, the scheme stage and construction stage of the precast decoration are advanced, and the design and construction are synchronized with the architectural scheme.
What is the “more, faster, better and less” of assembly decoration? Assembled decoration perfectly solves the problems exposed in traditional decoration.
The prevalence of “decoration guerrillas” in China has obviously restricted the development of the decoration industry.
Third, the decoration environment is seriously polluted.
Therefore, from the State Council to the local governments, they are vigorously developing the precast decoration, constantly improving the building assembly rate, and are widely used in more and more fields.
The construction phase shall be advanced and cross construction shall be carried out with the main structure.
Formaldehyde content in traditional decoration materials is high, which is easy to cause indoor pollution.
Due to its physical connection mode, multiple parts and products can be installed in parallel, so as to achieve process overlap and improve the overall installation speed of the project; A lot of manpower can be saved on site; Easy to achieve high quality of finished products; Easy to repair and replace; Because of its integration characteristics, when all parts and products have completed the construction of the technical system and the coding of the product family library, the digital reconstruction of the whole industrial chain from design, production, installation to operation and maintenance can be achieved, so as to achieve the goal of improving quality, improving efficiency, saving materials and labor, and saving energy and carbon.
