New technologies, new materials, new processes and new equipment used in precast residential projects shall pass the identification or evaluation organized by relevant departments.

The draft proposed that factory supervision should be implemented to control the quality of precast components from the source.

Based on the design concept of green buildings, the solar hot water system for precast residential buildings should adopt integrated components.

The toilet of the residence adopts the same floor drainage, and this drainage pipe setting mode can avoid the impact on the lower floor residents caused by the failure maintenance of the toilet pipe of the upper floor residents, the leakage of the toilet floor and the leakage of the drainage equipment floor drain connection.

There are many problems, such as the use of smell in kitchens or toilets on each floor, unclear property rights and not conducive to standardized modular design and construction.

Recently, the reporter learned from the Housing and Urban Rural Development Department of Anhui Province that the provincial local standard “Technical Regulations on Prevention and Control of Common Problems in the Quality of Assembled Housing Projects” is open for comments, which is expected to fill the technical gap in domestic housing quality.

Among them, there are 63 enterprises producing precast concrete components, with an annual production capacity of about 7 million cubic meters, and 50 enterprises producing precast steel structure components, with an annual production capacity of more than 5 million tons.

The processing capacity and production capacity of steel structures rank first in China.

The lighting in public areas such as corridors, staircases and hallways shall be equipped with automatic control devices such as voice control, light control, timing and induction.

Establish a building material quality traceability mechanism from production to use, and publicize relevant information to the society.

● The construction of precast rural housing again received media attention, Hefei TV reported that the precast farmhouses in Liyuan Village, Wushan Town helped build beautiful villages ● “We used to live in the most dilapidated house in the village, but now we live in the best house in the village” ——Representatives of the National Green Building Materials Technology Exchange Conference for Rural Revitalization visited the precast rural housing demonstration project Sidelights: Hefei Guorui Integrated Building Technology Co., Ltd.

In addition, the electrical equipment shall be safe, reliable, efficient and energy-saving products.

The lighting system in public areas shall comply with the control principle of energy-saving design.

At present, the kitchen and bathroom exhaust system and design of ordinary residential buildings mostly adopt the way of sharing vertical pipe wells.

In the draft for comments, the construction links such as kitchen and bathroom electrical which are easy to cause quality disputes are specifically clarified.

However, the precast building market is still faced with insufficient design capacity, low degree of design standardization, and quality problems in construction and installation as well as components and materials, especially the quality control of key nodes such as component installation is not in place.

The construction unit and the construction unit should purchase the housing project quality insurance.

In the construction of precast residential buildings, the kitchen and bathroom should be equipped with a horizontal exhaust system, which is conducive to solving similar problems.

The development of precast buildings in Anhui started early, and now a relatively complete policy, standard system and strong industrial support have been formed.
