Chengdu releases the fire design guide of the existing architectural reconstruction project

On June 15, the reporter learned from the Chengdu Housing and Urban Construction Bureau that in order to regulate and clarify the existing construction of fire fighting design and review, to ensure existing construction fire safety, the Chengdu Housing and Urban Construction Bureau issued the "Chengdu existing construction reconstruction projects in Chengdu "Fire Fighting Design Guide (2022)" (hereinafter referred to as the "Guide"), guidance has been put forward on how to apply new and old fire standards in different forms of renovation of the existing buildings.

Which existing architectural renovation project applies this guide?

The "Guide" clearly states that the completion of the completion of the project and put into use or the use of public buildings in accordance with the law and obtaining the reconstruction of housing property rights and the design and use function transformation of the design and use of the design and use is a applicable scope of the factory and warehouse transformation of civil buildings.

The reconstruction of residential buildings, temporary buildings, villagers' self -built houses, and public buildings is not applicable to the transformation of factories and warehouses. Cultural relics protection units, historical architecture, historical and cultural block reconstruction projects organize expert arguments in accordance with the principle of "one matter" in accordance with the principle of "one thing and one discussion".

Is there a form of transformation of architecture?

The "Guide" clearly states that both architectural transformation is divided into internal decoration, building facade reconstruction, overall building reconstruction, and local renovation of the building.

Internal decoration refers to the function of not changing the building design and use function, does not change the main structure, load -bearing wall, and does not change the division of the fire prevention district, the form of evacuation stairs, the location and width of the evacuation aisle, etc. In order to meet the needs of the use, Protection and fixed facilities installation. The facade reconstruction refers to the decoration and renovation project of only the facade of the building. The overall transformation refers to the all -ground and underground transformation of monomer buildings, all the transformation above ground, and all transformation projects of single -building basement. Local transformation refers to the transformation projects other than internal decoration, facade reconstruction, and overall transformation.

Is the work that needs to be carried out before the reconstruction of the building?

The "Guide" states that before the renovation of architecture, it is transformed into special functional places (transformed into medical buildings, elderly care facilities, childcare children, kindergarten children's rooms, children's play halls and other children's activity venues and public gathering places. In the venue), the construction unit shall carry out the feasibility assessment of fire technology by themselves or the design unit and fire technology service agency, and the renovation into other types of places is encouraged and implemented.

Are the applicable principles of both new and old fire standards?

The existing construction transformation shall implement the current fire protection technical standards. When there is indeed difficulty due to conditions, it shall be implemented in accordance with the relevant technical requirements of this guide, and strive to improve and improve the level of construction fire safety.

Are there any specific fire technology requirements for architecture transformation?

The "Guide" clearly states that for the four different types of transformation, if the building design and use functions have not changed, 15 technical requirements have been proposed; if the building design and use functions have changed, 16 technical requirements are proposed, and the transformation is particularly emphasized to be transformed into special functional places for special use functional places. The existing architectural transformation must implement the current standard;

What are the compensation measures for existing architectural fire protection design?

In response to the restrictions of existing architectural transformations due to the conditions such as actual venues or architecture itself, the "Guide" in total plane layout, fire prevention partition and flat layout, safe evacuation and evacuation, fire supply facilities, smoke -proof facilities, fire electricity and matching In the aspects of electricity, fire automatic alarm system and fire -fighting control system, emergency lighting and evacuation instruction system, 27 fire performance compensation measures have been proposed to ensure existing construction fire safety.
