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

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

There are many problems, such as the use of cross-flavor in the kitchen or bathroom on each floor, unclear property rights and not conducive to standardized modular design and construction.

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

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

In line with the design concept of green building, the solar hot water system of precast residential buildings should adopt integrated components.

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

The construction unit and the construction unit should purchase the quality insurance of the residential project.

The new technology, new material, new process and new equipment used in the precast housing project shall pass the identification or evaluation organized by relevant departments.

At present, the country has not formulated special standards or specifications for the prevention and control technology of common problems in the quality of precast housing projects.

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

The steel structure processing volume and capacity ranks first in the country.

Recently, the reporter learned from the Anhui Provincial Department of Housing and Urban-Rural Development that the provincial local standard “Technical Regulations for the 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.

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

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

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

The residential toilet adopts the same floor drainage, which can avoid the impact on the lower floor residents caused by the failure of the upper floor toilet pipe, the leakage of the toilet floor and the leakage of the drainage equipment floor drain connection.

In the solicitation draft, the construction links such as kitchen, bathroom and electrical equipment that are prone to cause quality disputes are specifically clarified.

Establish a quality traceability mechanism for building materials from production to use, and publicize relevant information to the public.
