If there is any mistake, I hope I will not hesitate to criticize and correct it.

At present, the cost side does not have an advantage, but with the gradual expansion of the production scale of each enterprise, The scale effect is expected to appear gradually.

According to the statistics of the Ministry of housing and urban rural development, precast buildings have achieved rapid development since 2012.

The skirting line is fixed under the cast wallboard through special clips, and finally the carpet is laid.

01 precast room construction technology exhibition room building area: 80 square meters, 6 construction workers, construction completed in 5 days.

At present, customers in the industry are mainly national security housing projects, long-term rental apartments and hotels..

02 construction technology exhibition of precast toilet the toilet shown below has a construction area of 6 square meters, and 2 operators are arranged to complete the construction in 2 days.

The decoration market of long-term rental apartments, hotels and hardbound houses is expanding, which will effectively promote the development of assembly.

Because all listed companies have just entered the production stage and the production capacity is small, the precast interior products produced per unit area are much more expensive than traditional products.

Assuming that the newly-built building area remains unchanged every year, calculated according to the proportion of precast buildings in Newly-built buildings in China reaching 15%, the newly-built precast building area will reach 940 million square meters in 2025, with an annualized compound growth rate of 14.4%.

Most importantly, this decoration method will make the living more comfortable, the decoration more healthy and environment-friendly, and the difficulty of repair and change after delivery will be reduced.

The wallboard shall be constructed vertically with special joint clamp keel.

04 at present, the development prospect of precast decoration is that the domestic decoration market is up to 4 trillion, while the market share of leading companies is less than 1%.

So far, the room decoration has been completed.

At present, the ideal markets include affordable housing, long-term rental apartments, hotels and hardbound rooms.

Measure and locate the floor drain and drainage hole, then open a hole in the PP waterproof chassis, weld the PP pipe △ install the PP waterproof chassis, the chassis is 10mm ~ 20mm away from the surrounding wall, seal the pipe interface, lay the ground marble on the waterproof site △ handle the marble ground joint, and construct the cast skirting line, Fix the cast skirting line on the edge of the waterproof chassis △ the bathroom adopts honeycomb aluminum plate composite ultra-thin marble, and the internal corner strip construction.

However, the characteristics of short construction period and easy disassembly of precast decoration are naturally suitable for expanding tob business.

Assembly creates efficiency for the industry and plays a significant role in the effective use of resources, reducing labor costs, obtaining the value of employees and improving the contradiction between supply and demand.

As the assembly type is still in the early stage of development, the assembly type decoration needs to be further improved in terms of parts library, production capacity, personalized design and consumer cognition, the consumption attribute needs to be improved, and the TOC end has not yet formed a scale.

Its rise provides new opportunities for the decoration industry and is likely to lead the future development of the industry.

③ Compared with the traditional decoration process, the construction period can be reduced by more than 60%, so as to realize “zero formaldehyde” and “use after installation”.

Assembly decoration is the product of refinement, systematization, specialization and innovation after the development of building decoration industry to a certain height.

The concentration of real estate enterprises continues to increase △ at present, the problem restricting the demand side of precast decoration is still the cost problem.

This paper is divided into two parts: Toilet decoration and assembly technology.

Traditional decoration enterprises encounter a series of problems such as management radius in the process of development, and the industry competition is very fierce.

On the last day, the construction of cast skirting line, ground construction and final cleaning shall be carried out.

On the fourth day, the construction of cast ceiling plate, air outlet and lamps will be carried out.

In 2019, the newly built precast building area reached 420 million square meters, with a year-on-year growth rate of 44.8%, accounting for 13.4% of the newly built building area.

In addition, the decoration results obtained by using the assembly method are more stable, industrialized production, and the product quality is no longer determined by the technology of each constructor.

Day 1: overall waterproof chassis construction, marble floor construction, cast skirting line construction and cast wallboard construction.

(it can not be completely achieved at present) ② the selection of surface materials is diverse and can be recycled.

Compared with the traditional decoration process, its outstanding characteristics are as follows: ① only water electricians and installers are needed, and traditional types of work such as bricklayer, carpenter and painter are cancelled.

Lifting Pin Anchor

The construction sequence of on-site installation is the ground, then the wall and finally the top.

The characteristics of standardized precast decoration and lack of personality make it not adaptable to home decoration.

▲ focus on “cutting-edge home” and get more high-quality information.

Use special external corner strips to install wall panels at external corners △ the next day, ceiling panels and lamps installation, air outlet installation, door and window sleeves and threshold stones construction, sanitary ware installation: Construction of keel clamps around the ceiling △ suspender construction, main keel construction, ceiling panel construction △ threshold stones construction, door and window sleeves installation, lamp strips Installation of air outlet and sanitary ware △ 03 compared with traditional decoration, what is the highlight of assembly decoration process? Covering the traditional decoration wall, top and ground, all decoration contents and all traditional decoration materials can be reflected in the assembly way.

In the early stage, the water and electricity pipelines are laid in the cast light partition board.

Fix the first honeycomb aluminum plate composite ultra-thin marble wallboard in the internal corner strip, and construct the keel of the special seam clamp of the wallboard, which shall be installed in turn.

The wall system construction shall be carried out in the first three days, and the room adopts socket assembly wall system.

As well as the analysis of the development prospect of precast decoration in the future, I have my humble opinion.

What kind of development direction to choose is the common confusion of many traditional decoration companies.

Due to the high cost, high difficulty and low flexibility of the development of precast buildings, the precast interior decoration fills the area where the precast buildings cannot be popularized quickly, which is conducive to the promotion of the process of housing industrialization.
