Compared with traditional decoration, it has the characteristics of “more, faster, better and less”, and its advantages are very obvious.

Second, there are many hidden dangers in the decoration process.

However, due to the combination of traditional decoration and main structure, it is inevitable to smash and chisel during the transformation, resulting in a large amount of construction waste and environmental pollution.

The serious dependence on manual operation has become an important factor for the low entry threshold and poor competition pattern of the traditional decoration industry.

Precast decoration is a new decoration method with industrialized thinking.

According to relevant research results, the number of deaths due to indoor pollution in China reaches 111000 every year, and 42.1% of the total number of newly added children with congenital disabilities is related to indoor air pollution.

Compared with the traditional decoration, the precast decoration design is more cost-effective than the separate design of each household.

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 interior decoration must face secondary transformation.

According to the experience data of Beijing affordable housing center, the construction period of a 50 square meter public rental house with precast decoration is only 6 days, while the traditional decoration period is 30 days, and the construction efficiency is significantly improved.

Before the construction stage, cross construction with the main structure.

That is, the equipment and pipelines are not embedded in the building structure, but filled in the gap between the six sides of the cast space and the supporting structure.

The parts are manufactured in the factory, and only installed and constructed on site.

There are many on-site links, many types of work, serious dependence on manual operations, long time-consuming, and difficult to ensure quality.

The decoration accuracy is greatly improved to millimeter level, the influence of human factors is greatly reduced, and the decoration quality is easier to be guaranteed, “good and economical”.

According to the research of “design and construction of precast decoration”, the annual loss caused by the secondary decoration is more than 30billion yuan.

Before the design stage, the requirements for the design ability of building structure and decoration integration will be significantly improved.

1、 Precast decoration: industry revolution, with obvious advantages.

Part customization emphasizes that although the precast decoration is industrialized, it still needs to meet personalized customization, so as to avoid secondary processing on site.

Building information model (BIM) is an important auxiliary tool for building integrated design.

Compared with traditional decoration: “heavy factory, light site, more, faster, better and less” ⚫ There are many disadvantages of traditional decoration, and the industry needs to be upgraded.

The so-called dry construction method is to avoid the wet operations such as gypsum putty leveling, mortar leveling, mortar bonding, etc.

Judging whether the decoration method is cast decoration should start from its technical characteristics and be summarized in the following three aspects: first, dry construction method assembly.

used in the traditional decoration method, but to use anchor bolts, supports, structural adhesives and other methods to realize the support and connection structure.

Because the traditional decoration will partially damage the protective layer of the main structure, and the behaviors such as wall chiseling are more likely to cause structural safety problems (such as the Quanzhou hotel incident), there are many on-site construction processes and complex processes, resulting in many hidden dangers in the process.

Fourth, material resources are seriously wasted.

From the perspective of project operation process, the scheme stage and construction stage of precast decoration are advanced, and the design and construction are synchronized with the architectural scheme.

The prevalence of “decoration guerrillas” in China has significantly restricted the development of the decoration industry.

All construction operations in the traditional decoration method are completed on site, while the assembly decoration divides the original construction operation into two parts: factory component production + on-site installation.

The common problems of moldy walls, wet and powdered walls and peeling of wall tops in traditional decorated houses are all caused by the difficulty in controlling the quality of traditional wet work; The problems of uneven ground and broken water and electricity pipes are all caused by poor construction accuracy.

The content of formaldehyde in traditional decoration materials is high, which is easy to cause indoor pollution.

1.

Component integration is to integrate multiple dispersed components and materials into an organism through specific manufacturing and supply, and realize dry construction method while improving performance, which is easy to deliver and assemble.

Compared with the traditional method, the assembly decoration “heavy factory, light site”.

2.

Specifically: first, there are many common problems in decoration quality.

From the point of view of the construction link, because the precast decoration is divided into two parts: factory part production + on-site installation, the factory part production does not affect the project progress, and the on-site installation requires all dry construction without secondary processing, so the construction cycle is significantly shortened compared with the traditional method.

The difficulty of on-site management has become the main obstacle for most decoration companies with limited management radius and difficult to break through the scale.

The design can be completed by a better team, and the cost can be shared by all users who choose the system.

From the perspective of products, the industrialized thinking design concept of precast decoration divides the eight decoration modules into a variety of parts, and the decoration company provides several options for each part, thus forming personalization in standardization and “more” product selectivity.

  ⚫ Precast decoration has obvious advantages of “more, faster, better and less”, which perfectly solves the disadvantages exposed by traditional decoration.

The second is the separation of pipeline and structure.

Precast decoration, also known as industrialized decoration, refers to the decoration method of using dry construction method to assemble and install the interior parts produced by the factory on site.

The traditional decoration method has been prevalent in China for a long time.

From the perspective of materials, the precast decoration adopts environmental protection materials such as calcium silicate composite board and rock wool, and the suppliers basically achieve zero formaldehyde, which is more environmentally friendly than traditional decoration; Although the price of environmental protection materials is relatively more expensive, the consumption of materials has decreased significantly..

Traditional decoration uses a large amount of materials during the first decoration, and the secondary renovation causes material waste.

Third, the decoration environment is heavily polluted.

Enterprises with technology accumulation in BIM will better reflect their competitive advantages in the competition of precast decoration industry.

Third, part integration and customization.

The precast decoration has the industrialized thinking of standardized design, industrialized production, precast construction and informatization coordination.
